2025-05-20 15:50:22There is something quietly rebellious about stacking sats. In a world obsessed with instant gratification, choosing to patiently accumulate Bitcoin, one sat at a time, feels like a middle finger to the hype machine. But to do it right, you have got to stay humble. Stack too hard with your head in the clouds, and you will trip over your own ego before the next halving even hits.
Small Wins
Stacking sats is not glamorous. Discipline. Stacking every day, week, or month, no matter the price, and letting time do the heavy lifting. Humility lives in that consistency. You are not trying to outsmart the market or prove you are the next "crypto" prophet. Just a regular person, betting on a system you believe in, one humble stack at a time. Folks get rekt chasing the highs. They ape into some shitcoin pump, shout about it online, then go silent when they inevitably get rekt. The ones who last? They stack. Just keep showing up. Consistency. Humility in action. Know the game is long, and you are not bigger than it.
Ego is Volatile
Bitcoin’s swings can mess with your head. One day you are up 20%, feeling like a genius and the next down 30%, questioning everything. Ego will have you panic selling at the bottom or over leveraging the top. Staying humble means patience, a true bitcoin zen. Do not try to "beat” Bitcoin. Ride it. Stack what you can afford, live your life, and let compounding work its magic.
Simplicity
There is a beauty in how stacking sats forces you to rethink value. A sat is worth less than a penny today, but every time you grab a few thousand, you plant a seed. It is not about flaunting wealth but rather building it, quietly, without fanfare. That mindset spills over. Cut out the noise: the overpriced coffee, fancy watches, the status games that drain your wallet. Humility is good for your soul and your stack. I have a buddy who has been stacking since 2015. Never talks about it unless you ask. Lives in a decent place, drives an old truck, and just keeps stacking. He is not chasing clout, he is chasing freedom. That is the vibe: less ego, more sats, all grounded in life.
The Big Picture
Stack those sats. Do it quietly, do it consistently, and do not let the green days puff you up or the red days break you down. Humility is the secret sauce, it keeps you grounded while the world spins wild. In a decade, when you look back and smile, it will not be because you shouted the loudest. It will be because you stayed the course, one sat at a time. \ \ Stay Humble and Stack Sats. 🫡

2025-05-16 17:12:05One of the most common criticisms leveled against nostr is the perceived lack of assurance when it comes to data storage. Critics argue that without a centralized authority guaranteeing that all data is preserved, important information will be lost. They also claim that running a relay will become prohibitively expensive. While there is truth to these concerns, they miss the mark. The genius of nostr lies in its flexibility, resilience, and the way it harnesses human incentives to ensure data availability in practice.
A nostr relay is simply a server that holds cryptographically verifiable signed data and makes it available to others. Relays are simple, flexible, open, and require no permission to run. Critics are right that operating a relay attempting to store all nostr data will be costly. What they miss is that most will not run all encompassing archive relays. Nostr does not rely on massive archive relays. Instead, anyone can run a relay and choose to store whatever subset of data they want. This keeps costs low and operations flexible, making relay operation accessible to all sorts of individuals and entities with varying use cases.
Critics are correct that there is no ironclad guarantee that every piece of data will always be available. Unlike bitcoin where data permanence is baked into the system at a steep cost, nostr does not promise that every random note or meme will be preserved forever. That said, in practice, any data perceived as valuable by someone will likely be stored and distributed by multiple entities. If something matters to someone, they will keep a signed copy.
Nostr is the Streisand Effect in protocol form. The Streisand effect is when an attempt to suppress information backfires, causing it to spread even further. With nostr, anyone can broadcast signed data, anyone can store it, and anyone can distribute it. Try to censor something important? Good luck. The moment it catches attention, it will be stored on relays across the globe, copied, and shared by those who find it worth keeping. Data deemed important will be replicated across servers by individuals acting in their own interest.
Nostr’s distributed nature ensures that the system does not rely on a single point of failure or a corporate overlord. Instead, it leans on the collective will of its users. The result is a network where costs stay manageable, participation is open to all, and valuable verifiable data is stored and distributed forever.

2025-05-15 01:22:34เมื่อพูดถึง Bitcoin Standard หลายคนมักนึกถึงภาพโลกอนาคตที่ทุกคนใช้บิตคอยน์ซื้อกาแฟหรือของใช้ในชีวิตประจำวัน ภาพแบบนั้นดูเหมือนไกลตัวและเป็นไปไม่ได้ในความเป็นจริง หลายคนถึงกับพูดว่า “คงไม่ทันเห็นในช่วงชีวิตนี้หรอก” แต่ในมุมมองของผม Bitcoin Standard อาจไม่ได้เริ่มต้นจากการที่เราจ่ายบิตคอยน์โดยตรงในร้านค้า แต่อาจเริ่มจากบางสิ่งที่เงียบกว่า ลึกกว่า และเกิดขึ้นแล้วในขณะนี้ นั่นคือ การล่มสลายทีละน้อยของระบบเฟียตที่เราใช้กันอยู่
ระบบเงินที่อิงกับอำนาจรัฐกำลังเข้าสู่ช่วงขาลง รัฐบาลทั่วโลกกำลังจมอยู่ในภาระหนี้ระดับประวัติการณ์ แม้แต่ประเทศมหาอำนาจก็เริ่มแสดงสัญญาณของภาวะเสี่ยงผิดนัดชำระหนี้ อัตราเงินเฟ้อกลายเป็นปัญหาเรื้อรังที่ไม่มีท่าทีจะหายไป ธนาคารที่เคยโอนฟรีเริ่มกลับมาคิดค่าธรรมเนียม และประชาชนก็เริ่มรู้สึกถึงการเสื่อมศรัทธาในระบบการเงินดั้งเดิม แม้จะยังพูดกันไม่เต็มเสียงก็ตาม
ในขณะเดียวกัน บิตคอยน์เองก็กำลังพัฒนาแบบเงียบ ๆ เงียบ... แต่ไม่เคยหยุด โดยเฉพาะในระดับ Layer 2 ที่เริ่มแสดงศักยภาพอย่างจริงจัง Lightning Network เป็น Layer 2 ที่เปิดใช้งานมาได้ระยะเวลสหนึ่ง และยังคงมีบทบาทสำคัญที่สุดในระบบนิเวศของบิตคอยน์ มันทำให้การชำระเงินเร็วขึ้น มีต้นทุนต่ำ และไม่ต้องบันทึกทุกธุรกรรมลงบล็อกเชน เครือข่ายนี้กำลังขยายตัวทั้งในแง่ของโหนดและการใช้งานจริงทั่วโลก
ขณะเดียวกัน Layer 2 ทางเลือกอื่นอย่าง Ark Protocol ก็กำลังพัฒนาเพื่อตอบโจทย์ด้านความเป็นส่วนตัวและประสบการณ์ใช้งานที่ง่าย BitVM เปิดแนวทางใหม่ให้บิตคอยน์รองรับ smart contract ได้ในระดับ Turing-complete ซึ่งทำให้เกิดความเป็นไปได้ในกรณีใช้งานอีกมากมาย และเทคโนโลยีที่น่าสนใจอย่าง Taproot Assets, Cashu และ Fedimint ก็ทำให้การออกโทเคนหรือสกุลเงินที่อิงกับบิตคอยน์เป็นจริงได้บนโครงสร้างของบิตคอยน์เอง
เทคโนโลยีเหล่านี้ไม่ใช่การเติบโตแบบปาฏิหาริย์ แต่มันคืบหน้าอย่างต่อเนื่องและมั่นคง และนั่นคือเหตุผลที่มันจะ “อยู่รอด” ได้ในระยะยาว เมื่อฐานของความน่าเชื่อถือไม่ใช่บริษัท รัฐบาล หรือทุน แต่คือสิ่งที่ตรวจสอบได้และเปลี่ยนกฎไม่ได้
แน่นอนว่าบิตคอยน์ต้องแข่งขันกับ stable coin, เงินดิจิทัลของรัฐ และ cryptocurrency อื่น ๆ แต่สิ่งที่ทำให้มันเหนือกว่านั้นไม่ใช่ฟีเจอร์ หากแต่เป็นความทนทาน และความมั่นคงของกฎที่ไม่มีใครเปลี่ยนได้ ไม่มีทีมพัฒนา ไม่มีบริษัท ไม่มีประตูปิด หรือการยึดบัญชี มันยืนอยู่บนคณิตศาสตร์ พลังงาน และเวลา
หลายกรณีใช้งานที่เคยถูกทดลองในโลกคริปโตจะค่อย ๆ เคลื่อนเข้ามาสู่บิตคอยน์ เพราะโครงสร้างของมันแข็งแกร่งกว่า ไม่ต้องการทีมพัฒนาแกนกลาง ไม่ต้องพึ่งกลไกเสี่ยงต่อการผูกขาด และไม่ต้องการ “ความเชื่อใจ” จากใครเลย
Bitcoin Standard ที่ผมพูดถึงจึงไม่ใช่การเปลี่ยนแปลงแบบพลิกหน้ามือเป็นหลังมือ แต่คือการ “เปลี่ยนฐานของระบบ” ทีละชั้น ระบบการเงินใหม่ที่อิงอยู่กับบิตคอยน์กำลังเกิดขึ้นแล้ว มันไม่ใช่โลกที่ทุกคนถือเหรียญบิตคอยน์ แต่มันคือโลกที่คนใช้อาจไม่รู้ตัวด้วยซ้ำว่า “สิ่งที่เขาใช้นั้นอิงอยู่กับบิตคอยน์”
ผู้คนอาจใช้เงินดิจิทัลที่สร้างบน Layer 3 หรือ Layer 4 ผ่านแอป ผ่านแพลตฟอร์ม หรือผ่านสกุลเงินใหม่ที่ดูไม่ต่างจากเดิม แต่เบื้องหลังของระบบจะผูกไว้กับบิตคอยน์
และถ้ามองในเชิงพัฒนาการ บิตคอยน์ก็เหมือนกับอินเทอร์เน็ต ครั้งหนึ่งอินเทอร์เน็ตก็ถูกมองว่าเข้าใจยาก ต้องพิมพ์ http ต้องรู้จัก TCP/IP ต้องตั้ง proxy เอง แต่ปัจจุบันผู้คนใช้งานอินเทอร์เน็ตโดยไม่รู้ว่าเบื้องหลังมีอะไรเลย บิตคอยน์กำลังเดินตามเส้นทางเดียวกัน โปรโตคอลกำลังถอยออกจากสายตา และวันหนึ่งเราจะ “ใช้มัน” โดยไม่ต้องรู้ว่ามันคืออะไร
หากนับจากช่วงเริ่มต้นของอินเทอร์เน็ตในยุค 1990 จนกลายเป็นโครงสร้างหลักของโลกในสองทศวรรษ เส้นเวลาของบิตคอยน์ก็กำลังเดินตามรอยเท้าของอินเทอร์เน็ต และถ้าเราเชื่อว่าวัฏจักรของเทคโนโลยีมีจังหวะของมันเอง เราก็จะรู้ว่า Bitcoin Standard นั้นไม่ใช่เรื่องของอนาคตไกลโพ้น แต่มันเกิดขึ้นแล้ว

2025-05-24 18:01:14Vivek Ramaswamy’s company bets on distressed bitcoin claims as its Bitcoin treasury strategy moves forward.
Strive Enterprises, an asset management firm co-founded by Vivek Ramaswamy, is exploring the acquisition of distressed bitcoin claims, with particular interest in around 75,000 BTC tied to the Mt. Gox bankruptcy estate. This move is part of the company’s broader strategy to build a Bitcoin treasury ahead of its planned merger with Asset Entities.
According to a document filed on May 20 with the Securities and Exchange Commission, Strive has partnered with 117 Castell Advisory Group to “identify and evaluate” distressed Bitcoin claims with confirmed legal judgments. Among these are approximately 75,000 BTC connected to Mt. Gox, with an estimated market value of $8 billion at current prices.
Essentially, Strive aims to acquire rights to bitcoins currently tied up in legal disputes, which can be purchased at a discount by those willing to take on the risk and wait for eventual recovery.
In a post on X, Strive’s CFO, Ben Pham, stated:
“Strive intends to use all available mechanisms, including novel financial strategies not used by other Bitcoin treasury companies, to maximize its exposure to the asset.”
The company also plans to buy cash at a discount by merging with publicly traded companies holding more cash than their stock value, using the excess funds to purchase additional Bitcoin.
Mt. Gox, the exchange that collapsed in 2014, is currently in the process of repaying creditors, with a deadline set for October 31, 2025.
In its SEC filing, Strive declared:
“This strategy is intended to allow Strive the opportunity to purchase Bitcoin exposure at a discount to market price, enhancing Bitcoin per share and supporting its goal of outperforming Bitcoin over the long run.”
At the beginning of May, Strive announced its merger plan with Asset Entities, a deal that would create the first publicly listed asset management firm focused on Bitcoin. The resulting company aims to join the growing number of firms adopting a Bitcoin treasury strategy.
The corporate treasury trend
Strive’s initiative to accumulate bitcoin mirrors that of other companies like Strategy and Japan’s Metaplanet. On May 19, Strategy, led by Michael Saylor, announced the purchase of an additional 7,390 BTC for $764.9 million, raising its total holdings to 576,230 BTC. On the same day, Metaplanet revealed it had acquired another 1,004 BTC, increasing its total to 7,800 BTC.

2025-05-24 18:01:13According to the ECB Executive Board member, the launch of the digital euro depends on the timing of the EU regulation.
The European Central Bank (ECB) is making progress in preparing for the digital euro. According to Piero Cipollone, ECB Executive Board member and coordinator of the project, the technical phase “is proceeding quickly and on schedule,” but moving to operational implementation still requires political approval of the regulation at the European level.
Speaking at the ‘Voices on the Future’ event organized by Ansa and Asvis, Cipollone outlined a possible timeline:
“If the regulation is approved at the start of 2026 — in the best-case scenario for the European legislative process — we could see the first transactions with the digital euro by mid-2028.”
Cipollone also highlighted Europe’s current dependence on electronic payment systems managed by non-European companies:
“Today in Europe, whenever we don’t use cash, any transaction online or at the supermarket has to go through credit cards, with their fees. The payment system relies on companies that aren’t based in Europe. You can see why it would make sense to have a system fully under our control.”
For the ECB board member, the digital euro would act as a direct alternative to cash in the digital world, working like “a banknote you can spend anywhere in Europe for any purpose.”
The digital euro project is part of the ECB’s broader strategy to strengthen the independence of Europe’s financial system. According to Cipollone and the Central Bank, Europe’s digital currency would be a key step toward greater autonomy in electronic payments, reducing reliance on infrastructure and services outside the European Union.

2025-05-24 18:01:12A new study reveals: 4 out of 5 Americans would like the US to convert some of its gold into Bitcoin.
A recent survey conducted by the Nakamoto Project revealed that a majority of Americans support converting a portion of the United States’ gold reserves into Bitcoin. The survey, carried out online by Qualtrics between February and March 2025, involved 3,345 participants with demographic characteristics representative of US census standards. Most respondents expressed a desire to convert between 1% and 30% of the gold reserves into BTC.
Troy Cross, co-founder of the Nakamoto Project, stated:
“When given a slider and asked to advise the US government on the right proportion of Bitcoin and gold, subjects were very reluctant to put that slider on 0% Bitcoin and 100% gold. Instead, they settled around 10% Bitcoin.”
One significant finding from the research is the correlation between age and openness to Bitcoin: younger respondents showed a greater inclination toward the cryptocurrency compared to older generations.
A potential US strategy
Bo Hines, a White House advisor, is promoting an initiative for the Treasury Department to acquire Bitcoin by selling off a portion of its gold. Under the proposed plan, the government could acquire up to 1 million BTC over the next five years.
To finance these purchases, the government plans to sell Federal Reserve gold certificates. The proposal aligns with Senator Cynthia Lummis’ 2025 Bitcoin Act, which aims to declare Bitcoin a critical national strategic asset.
Currently, the United States holds 8,133 metric tons of gold, valued at over $830 billion, and about 200,000 BTC, valued at $21 billion.

2025-05-22 14:01:52Gen Z (those born between 1997 and 2012) are not rushing to stack sats, and Oliver Porter, Founder & CEO of Jippi, understands the challenge better than most. His strategy revolves around adapting Bitcoin education to fit seamlessly into the digital lives of young adults.
“We need to meet them where they are,” Oliver explains. “90% of Gen Z plays games. 70% expect to earn rewards.”
So, what will effectively introduce them to Bitcoin? In Oliver’s mind, the answer is simple: games that don’t feel preachy but still plant the orange pill.
Learn more at Jippi.app
That’s exactly what Jippi is. Based in Austin, Texas, the team has created a mobile augmented reality (AR) game that rewards players in bitcoin and sneakily teaches them why sound money matters.
“It’s Pokémon GO… but for sats,” Oliver puts it succinctly.
Jippi is like Pokemon Go, but for sats
Oliver’s Bitcoin journey, like many in the space, began long before he was ready. A former colleague had tried planting the seed years earlier, handing him a copy of The Bitcoin Standard. But the moment passed.
It wasn’t until the chaos of 2020 when lockdowns hit, printing presses roared, and civil liberties shrank that the message finally landed for him.
“The government got so good at doing reverse Robin Hood,” Oliver explains. “They steal from the working population and reward the rich.”
By 2020, though, the absurdity of the covid hysteria had caused his eyes to be opened and the orange light seemed the best path back to freedom.
He left the UK for Austin “one of the best places for Bitcoiners,” he says, and dove headfirst into the industry, working at Swan for a year before founding Jippi on PlebLab’s accelerator program.
Jippi’s flagship game lets players roam their cities hunting digital creatures, Bitcoin Beasts, tied to real-world locations. Catching them requires answering Bitcoin trivia, and the reward is sats.
No jargon. No hour-long lectures. Just gameplay with sound money principles woven right in.
The model is working. At a recent hackathon in Austin, Jippi beat out 14 other teams to win first place and $15,000 in prize money.
Oliver of Jippi won Top Builder Season 2 — PlebLab on X
“We’re backdooring Bitcoin education,” Oliver admits. “And while we’re at it, encouraging people to get outside and touch grass.”
Not everyone’s been thrilled. When Jippi team members visited one of the more liberal-leaning places in Texas, UT Austin, to test interest in Bitcoin, they found some seriously committed no-coiners on the campus.
“One young woman told me, ‘I would rather die than talk about Bitcoin,'” Oliver recalls, highlighting the cultural resistance that’s built up among younger demographics.
This resistance is backed by hard data. According to Oliver, some of the Bitcoin podcasters they met with in the space to do market research reported that less than 1% of their listeners are from Gen Z and that number is dropping.
“Unless we find a way to capture their interest in a meaningful way, there’s going to be a big problem around trying to sway Gen Z away from the siren call of s***coins and crypto casinos and towards Bitcoin,” Oliver warns.
Jippi’s next big move is Las Vegas, where they’ll launch the Beast Catch experience at the Venetian during a major Bitcoin event. To mark the occasion, they’re opening up six limited sponsorship spots for Bitcoin companies, each one tied to a custom in-game beast.
Jippi looks to launch a special event at Bitcoin 2025
“It’s real estate inside the game,” Oliver explains. “Brands become allies, not intrusions. You get a logo, company name, and call to action, so we can push people to your site or app.”
Bitcoin Well—an automatic self-custody Bitcoin platform—has claimed Beast #1. Only five exclusive spots remain for Bitcoin companies to “beastify their brand” through Jippi’s immersive AR game.
“I love the Jippi mission. I think gamified learning is how we will onboard the next generation and it’s exciting to see what the Jippi team is doing! I love working with bitcoiners towards our common mission – bullish!” said Adam O’Brien, Bitcoin Well CEO.
Jippi’s sponsorship model is simple: align incentives, respect users, and support builders. Instead of throwing ad money at tech giants, Bitcoin companies can connect with new users naturally while they’re having fun and earning sats in the process.
For Bitcoin companies looking to reach a younger demographic, this represents a unique opportunity to showcase their brand to up to 30,000 potential customers at the Vegas event.
Jippi Bitcoin Beast partnership
While Jippi’s current focus is simple, get the game into more cities, Oliver sees a future where AR glasses and AI help personalize Bitcoin education even further.
“The magic is going to really happen when Apple releases the glasses form factor,” he says, describing how augmented reality could enhance real-world connections rather than isolate users.
In the longer term, Jippi aims to evolve from a free-to-play model toward a pay-to-play version with higher stakes. Users would form “tribes” with friends to compete for substantial bitcoin prizes, creating social connections along with financial education.
Unlike VC-backed startups, Jippi is raising funds pleb style via Timestamp, an open investment platform for Bitcoin companies.
“You don’t have to be an accredited investor,” Oliver explains. “You’re directly supporting the parallel Bitcoin economy by investing in Bitcoin companies for equity.”
Anyone can invest as little as $100. Perks include early access, exclusive game content, and even creating your own beast design with your name/pseudonym and unique game lore. Each investment comes with direct ownership of an early-stage Bitcoin company like Jippi.
For Oliver, this is more than just a business. It’s about future-proofing Bitcoin adoption and ensuring Satoshi’s vision lives on, especially as many people are lured by altcoins, NFTs, and social media dopamine.
“We’re on the right side of history,” he says firmly. “I want my grandkids to know that early on in the Bitcoin revolution, games like Jippi helped make it stick.”
In a world increasingly absorbed by screens and short attention spans, Jippi’s combination of outdoor play, sats rewards, and Bitcoin education might be exactly the bridge Gen Z needs.

2025-05-24 18:01:11The exchange reveals the extent of the breach that occurred last December as federal authorities investigate the recent data leak.
Coinbase has disclosed that the personal data of 69,461 users was compromised during the breach in December 2024, according to documentation filed with the Maine Attorney General’s Office.
The disclosure comes after Coinbase announced last week that a group of hackers had demanded a $20 million ransom, threatening to publish the stolen data on the dark web. The attackers allegedly bribed overseas customer service agents to extract information from the company’s systems.
Coinbase had previously stated that the breach affected less than 1% of its user base, compromising KYC (Know Your Customer) data such as names, addresses, and email addresses. In a filing with the U.S. Securities and Exchange Commission (SEC), the company clarified that passwords, private keys, and user funds were not affected.
Following the reports, the SEC has reportedly opened an official investigation to verify whether Coinbase may have inflated user metrics ahead of its 2021 IPO. Separately, the Department of Justice is investigating the breach at Coinbase’s request, according to CEO Brian Armstrong.
Meanwhile, Coinbase has faced criticism for its delayed response to the data breach. Michael Arrington, founder of TechCrunch, stated that the stolen data could cause irreparable harm. In a post on X, Arrington wrote:
“The human cost, denominated in misery, is much larger than the $400m or so they think it will actually cost the company to reimburse people. The consequences to companies who do not adequately protect their customer information should include, without limitation, prison time for executives.”
Coinbase estimates the incident could cost between $180 million and $400 million in remediation expenses and customer reimbursements.
Arrington also condemned KYC laws as ineffective and dangerous, calling on both regulators and companies to better protect user data:
“Combining these KYC laws with corporate profit maximization and lax laws on penalties for hacks like these means these issues will continue to happen. Both governments and corporations need to step up to stop this. As I said, the cost can only be measured in human suffering.”

2025-05-24 18:01:10Bitcoin adoption will come through businesses: neither governments nor banks will lead the revolution.
In recent years, it’s undeniable that Bitcoin has ceased to be just a radical idea born from the minds of cypherpunks. It is now recognized across the board as a global asset, discussed in the upper echelons of finance, accepted even on Wall Street, purchased by banking groups and included as a “strategic reserve” by some nations.
However, the general perception that hovers today regarding Bitcoin’s diffusion is still that of minimal adoption, almost insignificant. Bitcoin exists, certainly, but in fact it is not being used. It is rarely possible to pay in satoshis in commercial establishments. Demand is still extremely low.
Furthermore, the debate on Bitcoin is still practically absent: excluding some local events, some niche media outlets or some timid discussion, today Bitcoin is in fact excluded from general interest. The level of understanding and knowledge of the phenomenon is certainly still very low.
Yet, Bitcoin represents an unprecedented technological improvement, capable of solving many problems inherent in the fiat system in which we live. What could facilitate its diffusion?
Bitcoin becomes familiar when businesses adopt it
When talking about Bitcoin adoption, many look to States. They imagine governments that legislate or accumulate Bitcoin as a “strategic reserve,” or banks perceived as forward-thinking that would lead technological change, opening up to innovation. But the reality is different: bureaucracy, political constraints, and fear of losing control inherently prevent States and central banks from being pioneers.
What really drives Bitcoin adoption are not States, but businesses. It is the forward-looking entrepreneurs, innovative startups and – eventually – even large multinational companies that decide to integrate Bitcoin into their operating systems that drive adoption. Indeed, the business world has always played a key role in the adoption of new technologies. This was the case, for example, with the internet, e-commerce, mobile telephony, and the cloud. It will also be the case with Bitcoin.
Unlike a State, when a company adopts Bitcoin, it does so for concrete reasons: efficiency, savings, protection, access to new markets, independence from traditional banking circuits, or bureaucratic streamlining. It is a rational choice, not an ideological one, dictated by the intent to improve one’s competitiveness against the competition to survive in the market.
What is currently missing to facilitate adoption is, in all likelihood, a significant number of businesses that have decided to integrate Bitcoin into their company systems.
Bitcoin becomes “normal” when it is integrated into the operational flow of businesses. Holding and framing bitcoin on the balance sheet, paying an invoice, paying salaries to employees in satoshis, making value transfers globally thanks to the blockchain, allowing customers to pay via Lightning Network… when all this becomes possible with the same simplicity with which we use the euro or the dollar, Bitcoin stops being alternative and becomes the standard.
Businesses are not just users. They are adoption multipliers. When a company chooses Bitcoin, it is automatically proposing it to customers, employees, suppliers, and institutional stakeholders. Each business adoption equals tens, hundreds, or thousands of new eyes on Bitcoin.
People, after all, trust what they see every day: if your trusted restaurant accepts bitcoin, or if your favorite e-commerce platform uses it to receive international payments, or if your colleague receives it as a salary, then Bitcoin no longer appears to be a mysterious object. It finally begins to be perceived as a real, useful, and functioning tool.
The integration of a technology in companies helps make it understandable, accessible, and legitimate in the eyes of the public. This is how distrust is overcome: by making Bitcoin visible in daily life.
Bitcoin and businesses today
A River Financial report estimates that as of May 2025, only 5% of bitcoin is currently owned by private businesses. A still very small number.
According to research by River, in May 2025 businesses hold just over a million btc (about 5% of available monetary units). More than two-thirds of bitcoin (68.2%) are in the hands of private individuals.
To promote Bitcoin adoption, it is necessary today to support businesses in integrating this standard, leveraging all its enormous opportunities. Among others, this technology allows for fast, economical, and global payments. It eliminates intermediaries, increases transparency and security in value transfers. It removes bureaucratic frictions and allows opening up to a new global market.
Every sector can benefit from Bitcoin: e-commerce, tourism, industry, restaurants, professional services, or any other business. Bitcoin revolutionizes the concept of money, and money is a transversal working tool.
We are still at the beginning, but several signals are encouraging. According to a study by Bitwise and reported by Atlas21, in the first quarter of 2025, a growing number of US companies (+16.11% compared to the previous one) are including Bitcoin in their balance sheets, not just as a financial bet, but as a long-term strategy to protect their assets and access a decentralized monetary system to transfer value worldwide without resorting to financial intermediaries.
Who is driving the change?
Echoing the words of Roy Sheinfeld, CEO of Breez, the true potential of Bitcoin will be unleashed first and foremost from the work of developers, the true architects in designing and refining tools that are increasingly simple and intuitive to use for anyone, regardless of level of expertise. It is the developers – Roy rightly argued – who will enable us to “conquer the world.”
But probably that’s not enough: the next step is to make Bitcoin a globally accepted technological standard, changing its perception towards the general public. And this is where businesses come into play.
Guided by the market, technological innovation, and the desire to meet user demands, entrepreneurs today represent the fulcrum to accelerate the monetary transition from the current fiat system towards the Bitcoin standard. It is entrepreneurs who transform innovations from opportunities for a few to a reality shared by many.
The adoption of Bitcoin will therefore not arise from a sudden event, nor from the exclusive fruit of enthusiasts’ enthusiasm or from arbitrary political choices decreed by States or regulators.
The future of Bitcoin is built in the places where value is created every day: in companies, in their systems, and in their strategic decisions.
“If we conquer developers, we conquer the world. If we conquer businesses, we conquer adoption.”

2025-05-22 06:21:22You’ve probably seen it before.
You open an agency’s website or a freelancer’s portfolio. At the very top of the homepage, it says:
We design for startups.
You wait 3 seconds. The last word fades out and a new one fades in:
We design for agencies.
Wait 3 more seconds:
We design for founders.
I call this design pattern The Wheel of Nothing: a rotating list of audience segments meant to impress through inclusion and draw attention through motion… for absolutely no reason.
Revered brand studio Pentagram recently launched a new website. To my surprise, the homepage features the Wheel of Nothing front and center, boldly claiming:
We design Everything for Everyone…before cycling through more specific combinations every few seconds.

2025-05-24 18:01:09Governor Abbott will have to decide whether to sign the bill establishing a bitcoin reserve for the state.
Texas could become the third U.S. state to set up a strategic bitcoin reserve, following the approval of Senate Bill 21 by the state House, with 101 votes in favor and 42 against.
Lee Bratcher, founder and president of the Texas Blockchain Council, expressed confidence that Governor Greg Abbott will sign the legislative measure. In an interview with The Block, Bratcher said:
“I’ve talked to the governor about this personally, and I think he wants to see Texas lead in this way.”
The bill is expected to reach the governor’s desk within a week or two, according to Bratcher’s projections. If signed, Texas would follow in the footsteps of New Hampshire and Arizona in creating a state-held bitcoin reserve.
Despite Texas ranking as the world’s eighth-largest economy — ahead of many nations — the initial approach to the reserve will be cautious. Bratcher estimates the starting investment will be in the “tens of millions of dollars,” an amount he describes as “modest” for an economy the size of Texas. The responsibility for operational decisions would fall to the state comptroller, who acts as an executive accountant in charge of managing and investing public funds.
“My sense is that it will be in the tens of millions of dollars, which, while it sounds significant, is a very modest amount, for a state the size of Texas.” explained the president of the Texas Blockchain Council.
The road to approval
According to Bratcher, the idea of creating a state bitcoin reserve dates back to 2022 and represents the culmination of years of work by the Texas Blockchain Council. The organization has worked closely with lawmakers who shared the vision of seeing the state accumulate the world’s leading cryptocurrency. Additionally, Texas has long been home to numerous bitcoin mining companies.

2025-05-21 16:58:36The other day, I had the privilege of sitting down with one of my favorite living artists. Our conversation was so captivating that I felt compelled to share it. I’m leaving his name out for privacy.
Since our last meeting, I’d watched a documentary about his life, one he’d helped create. I told him how much I admired his openness in it. There’s something strange about knowing intimate details of someone’s life when they know so little about yours—it’s almost like I knew him too well for the kind of relationship we have.
He paused, then said quietly, with a shy grin, that watching the documentary made him realize how “odd and eccentric” he is. I laughed and told him he’s probably the sanest person I know. Because he’s lived fully, chasing love, passion, and purpose with hardly any regrets. He’s truly lived.
Today, I turn 44, and I’ll admit I’m a bit eccentric myself. I think I came into the world this way. I’ve made mistakes along the way, but I carry few regrets. Every misstep taught me something. And as I age, I’m not interested in blending in with the world—I’ll probably just lean further into my own brand of “weird.” I want to live life to the brim. The older I get, the more I see that the “normal” folks often seem less grounded than the eccentric artists who dare to live boldly. Life’s too short to just exist, actually live.
I’m not saying to be strange just for the sake of it. But I’ve seen what the crowd celebrates, and I’m not impressed. Forge your own path, even if it feels lonely or unpopular at times.
It’s easy to scroll through the news and feel discouraged. But actually, this is one of the most incredible times to be alive! I wake up every day grateful to be here, now. The future is bursting with possibility—I can feel it.
So, to my fellow weirdos on nostr: stay bold. Keep dreaming, keep pushing, no matter what’s trending. Stay wild enough to believe in a free internet for all. Freedom is radical—hold it tight. Live with the soul of an artist and the grit of a fighter. Thanks for inspiring me and so many others to keep hoping. Thank you all for making the last year of my life so special.

2025-05-21 13:07:14Earlier this year I launched the asknostr.site project which has been a great journey and learning experience. I had wanted to write down my goals and ideas with the project but didn't get to it yet. Primal launching the article editor was a trigger for me to go for it.
Ever since I joined Nostr i was looking for ways to apply my skillset solve a problem and help with adoption. Around Christmas I figured that a Quora/Stackoverflow alternative is something that needs to exist on Nostr.
Before I knew it I had a pretty decent prototype. And because the network already had so much awesome content, contributors and authors I was never discouraged by the challenge that kills so many good ideas -> "Where do I get the first users?".
Since the initial announcement I have received so much encouragement through zaps, likes, DM's, and maybe most of all seeing the increase in usage of the site and #asknostr content kept me going.
Current State
The current version of the site is stable and most bugs are hashed out. After logging in (remote signer, extension or nsec) you can engage with content through votes, comments and replies. Or simply ask a new question.
All content is stored in the site's own private relay and preprocessed/computed into a single data store (postgres) so the site is fast, accessible and crawl-able.
The site supports browsing hashtags, voting/commenting on answers, asking new questions and every contributor get their own profile (example). At the time of writing the site has 41k questions, almost 200k replies/comments and upwards of 5 million sats purely for #asknostr content.
What to expect/On my list
There are plenty of things and UI bugs that need love and between writing the draft of this post and hitting publish I shipped 3 minor bug fixes. Little by little, bit by bit...
In addition to all those small details here is an overview of the things on my own wish list:
-
Inline Zaps: Ability to zap from the asknostr.site interface. Click the zap button, specify or pick the number of sats zap away.
-
Contributor Rank: A leaderboard to add some gamification. More recognition to those nostriches that spend their time helping other people out
-
Search by Keyword: Search all content by keywords. Experiment with the index to show related questions or answers
-
Better User Profiles: Improve the user profile so it shows all the profile questions and answers. Quick buttons to follow or zap that person. Better insights in the topics (hashtags) the profile contributes to
-
Bookmarks: Ability to bookmark questions and answers. Increase bookmark weight as a signal to rank answers.
-
Smarter Scoring: Tune how answers are scored (winning answer formula). Perhaps give more weight to the question author or use WoT. Not sure yet.
All of this is happening at some point so follow me if you want to stay up to date.
Goals
To manage expectations and keep me focussed I write down the mid and long term goals of the project.
Long term
Call me cheesy but I believe that humanity will flourish through an open web and sound money. My own journey started from with bitcoin but if you asked me today if it's BTC or nostr that is going to have the most impact I wouldn't know what to answer. Chicken or egg?
The goal of the project is to offer an open platform that empowers individuals to ask questions, share expertise and access high-quality information across different topics. The project empowers anyone to monetize their experience creating a sustainable ecosystem that values and rewards knowledge sharing. This will ultimately democratize access to knowledge for all.
Mid term
The project can help a lot with onboarding new users onto the network. Once we start to rank on certain topics we can get a piece of the search traffic pie (StackOverflows 12 million, and Quora 150 million visitors per month) which is a great way to expose people to the power of the network.
First time visitors do not need to know about nostr or zaps to receive value. They can browse around, discover interesting content and perhaps even create a profile without even knowing they are on Nostr now.
Gradually those users will understand the value of the network through better rankings (zaps beats likes), a cross-client experience and a profile that can be used on any nostr site or app.
In order for the site to do that we need to make sure content is browsable by language, (sub)topics and and we double down on 'the human touch' with real contributors and not LLMs.
Short Term Goal
The first goal is to make the site really good and an important resource for existing Nostr users. Enable visitors to search and discover what they are interested in. Integrate within the existing nostr eco system with 'open in' functionality and quick links to interesting projects (followerpacks?)
One of things i want to get right is to improve user retention by making the whole Q\&A experience more sticky. I want to run some experiments (bots, award, summaries) to get more people to use asknostr.site more often and come back.
What about the name?
Finally the big question: What about the asknostr.site name? I don't like the name that much but it's what people know. I think there is a high chance that people will discover Nostr apps like Olas, Primal or Damus without needing to know what NOSTR is or means.
Therefore I think there is a good chance that the project won't be called asknostr.site forever. I guess it all depends on where we all take this.
Onwards!

2025-05-21 05:47:41As a product builder over too many years to mention, I’ve lost count of the number of times I’ve seen promising ideas go from zero to hero in a few weeks, only to fizzle out within months.
The problem with most finance apps, however, is that they often become a reflection of the internal politics of the business rather than an experience solely designed around the customer. This means that the focus is on delivering as many features and functionalities as possible to satisfy the needs and desires of competing internal departments, rather than providing a clear value proposition that is focused on what the people out there in the real world want. As a result, these products can very easily bloat to become a mixed bag of confusing, unrelated and ultimately unlovable customer experiences—a feature salad, you might say.
Financial products, which is the field I work in, are no exception. With people’s real hard-earned money on the line, user expectations running high, and a crowded market, it’s tempting to throw as many features at the wall as possible and hope something sticks. But this approach is a recipe for disaster.
Here’s why: https://alistapart.com/article/from-beta-to-bedrock-build-products-that-stick/

2025-05-24 18:01:08Bitcoin surpasses gold in the United States: 50 million holders and a dominant role in the global market.
According to a new report by River, for the first time in history, the number of Americans owning bitcoin has surpassed that of gold holders. The analysis reveals that approximately 50 million U.S. citizens currently own the cryptocurrency, while gold owners number 37 million. In fact, 14.3% of Americans own bitcoin, the highest percentage of holders worldwide.
Source: River
The report highlights that 40% of all Bitcoin-focused companies are based in the United States, consolidating America’s dominant position in the sector. Additionally, 40.5% of Bitcoin holders are men aged 31 to 35, followed by 35.9% of men aged 41 to 45. In contrast, only 13.4% of holders are women.
Source: River
Notably, U.S. companies hold 94.8% of all bitcoins owned by publicly traded companies worldwide. According to the report, recent regulatory changes in the U.S. have made the asset more accessible through financial products such as spot ETFs.
The document also shows that American investors increasingly view the cryptocurrency as protection against fiscal instability and inflation, appreciating its limited supply and decentralized governance model.
For River, Bitcoin offers significant practical advantages over gold in the modern digital era. Its ease of custody, cross-border transfer, and liquidity make the cryptocurrency an attractive option for both individual and institutional investors, the report suggests.

@ 04c915da:3dfbecc9
2025-05-20 15:47:16Here’s a revised timeline of macro-level events from The Mandibles: A Family, 2029–2047 by Lionel Shriver, reimagined in a world where Bitcoin is adopted as a widely accepted form of money, altering the original narrative’s assumptions about currency collapse and economic control. In Shriver’s original story, the failure of Bitcoin is assumed amid the dominance of the bancor and the dollar’s collapse. Here, Bitcoin’s success reshapes the economic and societal trajectory, decentralizing power and challenging state-driven outcomes.
Part One: 2029–2032
-
2029 (Early Year)\ The United States faces economic strain as the dollar weakens against global shifts. However, Bitcoin, having gained traction emerges as a viable alternative. Unlike the original timeline, the bancor—a supranational currency backed by a coalition of nations—struggles to gain footing as Bitcoin’s decentralized adoption grows among individuals and businesses worldwide, undermining both the dollar and the bancor.
-
2029 (Mid-Year: The Great Renunciation)\ Treasury bonds lose value, and the government bans Bitcoin, labeling it a threat to sovereignty (mirroring the original bancor ban). However, a Bitcoin ban proves unenforceable—its decentralized nature thwarts confiscation efforts, unlike gold in the original story. Hyperinflation hits the dollar as the U.S. prints money, but Bitcoin’s fixed supply shields adopters from currency devaluation, creating a dual-economy split: dollar users suffer, while Bitcoin users thrive.
-
2029 (Late Year)\ Dollar-based inflation soars, emptying stores of goods priced in fiat currency. Meanwhile, Bitcoin transactions flourish in underground and online markets, stabilizing trade for those plugged into the bitcoin ecosystem. Traditional supply chains falter, but peer-to-peer Bitcoin networks enable local and international exchange, reducing scarcity for early adopters. The government’s gold confiscation fails to bolster the dollar, as Bitcoin’s rise renders gold less relevant.
-
2030–2031\ Crime spikes in dollar-dependent urban areas, but Bitcoin-friendly regions see less chaos, as digital wallets and smart contracts facilitate secure trade. The U.S. government doubles down on surveillance to crack down on bitcoin use. A cultural divide deepens: centralized authority weakens in Bitcoin-adopting communities, while dollar zones descend into lawlessness.
-
2032\ By this point, Bitcoin is de facto legal tender in parts of the U.S. and globally, especially in tech-savvy or libertarian-leaning regions. The federal government’s grip slips as tax collection in dollars plummets—Bitcoin’s traceability is low, and citizens evade fiat-based levies. Rural and urban Bitcoin hubs emerge, while the dollar economy remains fractured.
Time Jump: 2032–2047
- Over 15 years, Bitcoin solidifies as a global reserve currency, eroding centralized control. The U.S. government adapts, grudgingly integrating bitcoin into policy, though regional autonomy grows as Bitcoin empowers local economies.
Part Two: 2047
-
2047 (Early Year)\ The U.S. is a hybrid state: Bitcoin is legal tender alongside a diminished dollar. Taxes are lower, collected in BTC, reducing federal overreach. Bitcoin’s adoption has decentralized power nationwide. The bancor has faded, unable to compete with Bitcoin’s grassroots momentum.
-
2047 (Mid-Year)\ Travel and trade flow freely in Bitcoin zones, with no restrictive checkpoints. The dollar economy lingers in poorer areas, marked by decay, but Bitcoin’s dominance lifts overall prosperity, as its deflationary nature incentivizes saving and investment over consumption. Global supply chains rebound, powered by bitcoin enabled efficiency.
-
2047 (Late Year)\ The U.S. is a patchwork of semi-autonomous zones, united by Bitcoin’s universal acceptance rather than federal control. Resource scarcity persists due to past disruptions, but economic stability is higher than in Shriver’s original dystopia—Bitcoin’s success prevents the authoritarian slide, fostering a freer, if imperfect, society.
Key Differences
- Currency Dynamics: Bitcoin’s triumph prevents the bancor’s dominance and mitigates hyperinflation’s worst effects, offering a lifeline outside state control.
- Government Power: Centralized authority weakens as Bitcoin evades bans and taxation, shifting power to individuals and communities.
- Societal Outcome: Instead of a surveillance state, 2047 sees a decentralized, bitcoin driven world—less oppressive, though still stratified between Bitcoin haves and have-nots.
This reimagining assumes Bitcoin overcomes Shriver’s implied skepticism to become a robust, adopted currency by 2029, fundamentally altering the novel’s bleak trajectory.

Exibe uso dos discos do subvolume:
bash btrfs filesystem df /mnt
Balancea os dados entre os discos sobre raid1:
bash btrfs filesystem balance start -dconvert=raid1 -mconvert=raid1 /mnt
Scrub é uma passagem por todos os dados e metadados do sistema de arquivos e verifica as somas de verificação. Se uma cópia válida estiver disponível (perfis de grupo de blocos replicados), a danificada será reparada. Todas as cópias dos perfis replicados são validadas.
iniciar o processo de depuração :
bash btrfs scrub start /mnt
ver o status do processo de depuração Btrfs em execução:
bash btrfs scrub status /mnt
ver o status do scrub Btrfs para cada um dos dispositivos
bash btrfs scrub status -d / data btrfs scrub cancel / data
Para retomar o processo de depuração do Btrfs que você cancelou ou pausou:
btrfs scrub resume / data
Listando os subvolumes:
bash btrfs subvolume list /Reports
Criando um instantâneo dos subvolumes:
Aqui, estamos criando um instantâneo de leitura e gravação chamado snap de marketing do subvolume de marketing.
bash btrfs subvolume snapshot /Reports/marketing /Reports/marketing-snap
Além disso, você pode criar um instantâneo somente leitura usando o sinalizador -r conforme mostrado. O marketing-rosnap é um instantâneo somente leitura do subvolume de marketing
bash btrfs subvolume snapshot -r /Reports/marketing /Reports/marketing-rosnap
Forçar a sincronização do sistema de arquivos usando o utilitário 'sync'
Para forçar a sincronização do sistema de arquivos, invoque a opção de sincronização conforme mostrado. Observe que o sistema de arquivos já deve estar montado para que o processo de sincronização continue com sucesso.
bash btrfs filsystem sync /Reports
Para excluir o dispositivo do sistema de arquivos, use o comando device delete conforme mostrado.
bash btrfs device delete /dev/sdc /Reports
Para sondar o status de um scrub, use o comando scrub status com a opção -dR .
bash btrfs scrub status -dR / Relatórios
Para cancelar a execução do scrub, use o comando scrub cancel .
bash $ sudo btrfs scrub cancel / Reports
Para retomar ou continuar com uma depuração interrompida anteriormente, execute o comando de cancelamento de depuração
bash sudo btrfs scrub resume /Reports
mostra o uso do dispositivo de armazenamento:
btrfs filesystem usage /data
Para distribuir os dados, metadados e dados do sistema em todos os dispositivos de armazenamento do RAID (incluindo o dispositivo de armazenamento recém-adicionado) montados no diretório /data , execute o seguinte comando:
sudo btrfs balance start --full-balance /data
Pode demorar um pouco para espalhar os dados, metadados e dados do sistema em todos os dispositivos de armazenamento do RAID se ele contiver muitos dados.
Opções importantes de montagem Btrfs
Nesta seção, vou explicar algumas das importantes opções de montagem do Btrfs. Então vamos começar.
As opções de montagem Btrfs mais importantes são:
**1. acl e noacl
**ACL gerencia permissões de usuários e grupos para os arquivos/diretórios do sistema de arquivos Btrfs.
A opção de montagem acl Btrfs habilita ACL. Para desabilitar a ACL, você pode usar a opção de montagem noacl .
Por padrão, a ACL está habilitada. Portanto, o sistema de arquivos Btrfs usa a opção de montagem acl por padrão.
**2. autodefrag e noautodefrag
**Desfragmentar um sistema de arquivos Btrfs melhorará o desempenho do sistema de arquivos reduzindo a fragmentação de dados.
A opção de montagem autodefrag permite a desfragmentação automática do sistema de arquivos Btrfs.
A opção de montagem noautodefrag desativa a desfragmentação automática do sistema de arquivos Btrfs.
Por padrão, a desfragmentação automática está desabilitada. Portanto, o sistema de arquivos Btrfs usa a opção de montagem noautodefrag por padrão.
**3. compactar e compactar-forçar
**Controla a compactação de dados no nível do sistema de arquivos do sistema de arquivos Btrfs.
A opção compactar compacta apenas os arquivos que valem a pena compactar (se compactar o arquivo economizar espaço em disco).
A opção compress-force compacta todos os arquivos do sistema de arquivos Btrfs, mesmo que a compactação do arquivo aumente seu tamanho.
O sistema de arquivos Btrfs suporta muitos algoritmos de compactação e cada um dos algoritmos de compactação possui diferentes níveis de compactação.
Os algoritmos de compactação suportados pelo Btrfs são: lzo , zlib (nível 1 a 9) e zstd (nível 1 a 15).
Você pode especificar qual algoritmo de compactação usar para o sistema de arquivos Btrfs com uma das seguintes opções de montagem:
- compress=algoritmo:nível
- compress-force=algoritmo:nível
Para obter mais informações, consulte meu artigo Como habilitar a compactação do sistema de arquivos Btrfs .
**4. subvol e subvolid
**Estas opções de montagem são usadas para montar separadamente um subvolume específico de um sistema de arquivos Btrfs.
A opção de montagem subvol é usada para montar o subvolume de um sistema de arquivos Btrfs usando seu caminho relativo.
A opção de montagem subvolid é usada para montar o subvolume de um sistema de arquivos Btrfs usando o ID do subvolume.
Para obter mais informações, consulte meu artigo Como criar e montar subvolumes Btrfs .
**5. dispositivo
A opção de montagem de dispositivo** é usada no sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs.
Em alguns casos, o sistema operacional pode falhar ao detectar os dispositivos de armazenamento usados em um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs. Nesses casos, você pode usar a opção de montagem do dispositivo para especificar os dispositivos que deseja usar para o sistema de arquivos de vários dispositivos Btrfs ou RAID.
Você pode usar a opção de montagem de dispositivo várias vezes para carregar diferentes dispositivos de armazenamento para o sistema de arquivos de vários dispositivos Btrfs ou RAID.
Você pode usar o nome do dispositivo (ou seja, sdb , sdc ) ou UUID , UUID_SUB ou PARTUUID do dispositivo de armazenamento com a opção de montagem do dispositivo para identificar o dispositivo de armazenamento.
Por exemplo,
- dispositivo=/dev/sdb
- dispositivo=/dev/sdb,dispositivo=/dev/sdc
- dispositivo=UUID_SUB=490a263d-eb9a-4558-931e-998d4d080c5d
- device=UUID_SUB=490a263d-eb9a-4558-931e-998d4d080c5d,device=UUID_SUB=f7ce4875-0874-436a-b47d-3edef66d3424
**6. degraded
A opção de montagem degradada** permite que um RAID Btrfs seja montado com menos dispositivos de armazenamento do que o perfil RAID requer.
Por exemplo, o perfil raid1 requer a presença de 2 dispositivos de armazenamento. Se um dos dispositivos de armazenamento não estiver disponível em qualquer caso, você usa a opção de montagem degradada para montar o RAID mesmo que 1 de 2 dispositivos de armazenamento esteja disponível.
**7. commit
A opção commit** mount é usada para definir o intervalo (em segundos) dentro do qual os dados serão gravados no dispositivo de armazenamento.
O padrão é definido como 30 segundos.
Para definir o intervalo de confirmação para 15 segundos, você pode usar a opção de montagem commit=15 (digamos).
**8. ssd e nossd
A opção de montagem ssd** informa ao sistema de arquivos Btrfs que o sistema de arquivos está usando um dispositivo de armazenamento SSD, e o sistema de arquivos Btrfs faz a otimização SSD necessária.
A opção de montagem nossd desativa a otimização do SSD.
O sistema de arquivos Btrfs detecta automaticamente se um SSD é usado para o sistema de arquivos Btrfs. Se um SSD for usado, a opção de montagem de SSD será habilitada. Caso contrário, a opção de montagem nossd é habilitada.
**9. ssd_spread e nossd_spread
A opção de montagem ssd_spread** tenta alocar grandes blocos contínuos de espaço não utilizado do SSD. Esse recurso melhora o desempenho de SSDs de baixo custo (baratos).
A opção de montagem nossd_spread desativa o recurso ssd_spread .
O sistema de arquivos Btrfs detecta automaticamente se um SSD é usado para o sistema de arquivos Btrfs. Se um SSD for usado, a opção de montagem ssd_spread será habilitada. Caso contrário, a opção de montagem nossd_spread é habilitada.
**10. descarte e nodiscard
Se você estiver usando um SSD que suporte TRIM enfileirado assíncrono (SATA rev3.1), a opção de montagem de descarte** permitirá o descarte de blocos de arquivos liberados. Isso melhorará o desempenho do SSD.
Se o SSD não suportar TRIM enfileirado assíncrono, a opção de montagem de descarte prejudicará o desempenho do SSD. Nesse caso, a opção de montagem nodiscard deve ser usada.
Por padrão, a opção de montagem nodiscard é usada.
**11. norecovery
Se a opção de montagem norecovery** for usada, o sistema de arquivos Btrfs não tentará executar a operação de recuperação de dados no momento da montagem.
**12. usebackuproot e nousebackuproot
Se a opção de montagem usebackuproot for usada, o sistema de arquivos Btrfs tentará recuperar qualquer raiz de árvore ruim/corrompida no momento da montagem. O sistema de arquivos Btrfs pode armazenar várias raízes de árvore no sistema de arquivos. A opção de montagem usebackuproot** procurará uma boa raiz de árvore e usará a primeira boa que encontrar.
A opção de montagem nousebackuproot não verificará ou recuperará raízes de árvore inválidas/corrompidas no momento da montagem. Este é o comportamento padrão do sistema de arquivos Btrfs.
**13. space_cache, space_cache=version, nospace_cache e clear_cache
A opção de montagem space_cache** é usada para controlar o cache de espaço livre. O cache de espaço livre é usado para melhorar o desempenho da leitura do espaço livre do grupo de blocos do sistema de arquivos Btrfs na memória (RAM).
O sistema de arquivos Btrfs suporta 2 versões do cache de espaço livre: v1 (padrão) e v2
O mecanismo de cache de espaço livre v2 melhora o desempenho de sistemas de arquivos grandes (tamanho de vários terabytes).
Você pode usar a opção de montagem space_cache=v1 para definir a v1 do cache de espaço livre e a opção de montagem space_cache=v2 para definir a v2 do cache de espaço livre.
A opção de montagem clear_cache é usada para limpar o cache de espaço livre.
Quando o cache de espaço livre v2 é criado, o cache deve ser limpo para criar um cache de espaço livre v1 .
Portanto, para usar o cache de espaço livre v1 após a criação do cache de espaço livre v2 , as opções de montagem clear_cache e space_cache=v1 devem ser combinadas: clear_cache,space_cache=v1
A opção de montagem nospace_cache é usada para desabilitar o cache de espaço livre.
Para desabilitar o cache de espaço livre após a criação do cache v1 ou v2 , as opções de montagem nospace_cache e clear_cache devem ser combinadas: clear_cache,nosapce_cache
**14. skip_balance
Por padrão, a operação de balanceamento interrompida/pausada de um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs será retomada automaticamente assim que o sistema de arquivos Btrfs for montado. Para desabilitar a retomada automática da operação de equilíbrio interrompido/pausado em um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs, você pode usar a opção de montagem skip_balance .**
**15. datacow e nodatacow
A opção datacow** mount habilita o recurso Copy-on-Write (CoW) do sistema de arquivos Btrfs. É o comportamento padrão.
Se você deseja desabilitar o recurso Copy-on-Write (CoW) do sistema de arquivos Btrfs para os arquivos recém-criados, monte o sistema de arquivos Btrfs com a opção de montagem nodatacow .
**16. datasum e nodatasum
A opção datasum** mount habilita a soma de verificação de dados para arquivos recém-criados do sistema de arquivos Btrfs. Este é o comportamento padrão.
Se você não quiser que o sistema de arquivos Btrfs faça a soma de verificação dos dados dos arquivos recém-criados, monte o sistema de arquivos Btrfs com a opção de montagem nodatasum .
Perfis Btrfs
Um perfil Btrfs é usado para informar ao sistema de arquivos Btrfs quantas cópias dos dados/metadados devem ser mantidas e quais níveis de RAID devem ser usados para os dados/metadados. O sistema de arquivos Btrfs contém muitos perfis. Entendê-los o ajudará a configurar um RAID Btrfs da maneira que você deseja.
Os perfis Btrfs disponíveis são os seguintes:
single : Se o perfil único for usado para os dados/metadados, apenas uma cópia dos dados/metadados será armazenada no sistema de arquivos, mesmo se você adicionar vários dispositivos de armazenamento ao sistema de arquivos. Assim, 100% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser utilizado.
dup : Se o perfil dup for usado para os dados/metadados, cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos manterá duas cópias dos dados/metadados. Assim, 50% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser utilizado.
raid0 : No perfil raid0 , os dados/metadados serão divididos igualmente em todos os dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, não haverá dados/metadados redundantes (duplicados). Assim, 100% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser usado. Se, em qualquer caso, um dos dispositivos de armazenamento falhar, todo o sistema de arquivos será corrompido. Você precisará de pelo menos dois dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid0 .
raid1 : No perfil raid1 , duas cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a uma falha de unidade. Mas você pode usar apenas 50% do espaço total em disco. Você precisará de pelo menos dois dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1 .
raid1c3 : No perfil raid1c3 , três cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a duas falhas de unidade, mas você pode usar apenas 33% do espaço total em disco. Você precisará de pelo menos três dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1c3 .
raid1c4 : No perfil raid1c4 , quatro cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a três falhas de unidade, mas você pode usar apenas 25% do espaço total em disco. Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1c4 .
raid10 : No perfil raid10 , duas cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos, como no perfil raid1 . Além disso, os dados/metadados serão divididos entre os dispositivos de armazenamento, como no perfil raid0 .
O perfil raid10 é um híbrido dos perfis raid1 e raid0 . Alguns dos dispositivos de armazenamento formam arrays raid1 e alguns desses arrays raid1 são usados para formar um array raid0 . Em uma configuração raid10 , o sistema de arquivos pode sobreviver a uma única falha de unidade em cada uma das matrizes raid1 .
Você pode usar 50% do espaço total em disco na configuração raid10 . Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid10 .
raid5 : No perfil raid5 , uma cópia dos dados/metadados será dividida entre os dispositivos de armazenamento. Uma única paridade será calculada e distribuída entre os dispositivos de armazenamento do array RAID.
Em uma configuração raid5 , o sistema de arquivos pode sobreviver a uma única falha de unidade. Se uma unidade falhar, você pode adicionar uma nova unidade ao sistema de arquivos e os dados perdidos serão calculados a partir da paridade distribuída das unidades em execução.
Você pode usar 1 00x(N-1)/N % do total de espaços em disco na configuração raid5 . Aqui, N é o número de dispositivos de armazenamento adicionados ao sistema de arquivos. Você precisará de pelo menos três dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid5 .
raid6 : No perfil raid6 , uma cópia dos dados/metadados será dividida entre os dispositivos de armazenamento. Duas paridades serão calculadas e distribuídas entre os dispositivos de armazenamento do array RAID.
Em uma configuração raid6 , o sistema de arquivos pode sobreviver a duas falhas de unidade ao mesmo tempo. Se uma unidade falhar, você poderá adicionar uma nova unidade ao sistema de arquivos e os dados perdidos serão calculados a partir das duas paridades distribuídas das unidades em execução.
Você pode usar 100x(N-2)/N % do espaço total em disco na configuração raid6 . Aqui, N é o número de dispositivos de armazenamento adicionados ao sistema de arquivos. Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid6 .

Bitcoin je peer to peer elektronski keš, novi oblik digitalnog novca koji se može prenositi između ljudi ili računara, bez potrebe za učestvovanjem pouzdanog posrednika (kao što je banka) i čije izdavanje nije pod kontrolom nijedne stranke.
Zamislite papirni dolar ili metalni novčić. Kad taj novac date drugoj osobi, ona ne mora da zna ko ste vi.
On samo treba da veruju da novac koji dobiju od vas nije falsifikat. Obično, proveravanje falsifikata „fizičkog“ novca, ljudi rade koristeći samo oči i prste ili koristeći specijalnu opremu za testiranje ukoliko se radi o značajnijoj sumi novca.
Većina plaćanja u našem digitalnom društvu vrši se putem Interneta korišćenjem neke posredničke usluge: kompanije za izdavanje kreditnih kartica poput Visa, snabdevača digitalnih plaćanja kao što je PayPal ili Apple Pay ili mrežne platforme poput WeChat u Kini.
Kretanje ka digitalnom plaćanju sa sobom donosi oslanjanje na nekog centralnog aktera koji mora odobriti i verifikovati svaku uplatu.
Priroda novca se promenila od fizičkog predmeta koji možete da nosite, prenesete i autentifikujete do digitalnih bitova koje mora da čuva i verifikuje treća strana koja kontroliše njihov prenos.
Odricanjem od gotovine u korist „udobnih“ digitalnih plaćanja, mi takođe stvaramo sistem u kome dajemo ogromna ovlašćenja onima koji bi poželeli da nas tlače.
Platforme za digitalno plaćanje postale su osnova distopijskih autoritarnih metoda kontrole, poput onih koje kineska vlada koristi za nadgledanje disidenata i sprečava građane, čije ponašanje im se ne svidja, da kupuju robu i plaćaju usluge.
Bitcoin nudi alternativu centralno kontrolisanom digitalnom novcu sa sistemom koji nam vraća prirodu korišćenja keša – čovek čoveku, ali u digitalnom obliku.
Bitcoin je digitalno sredstvo koje se izdaje i prenosi preko mreže međusobno povezanih računara, od koji svaki od njih samostalno potvrđuje da svi ostali igraju po pravilima.
Bitcoin Mreža
Odakle Potiče Bitcoin?
Bitcoin je izumela osoba ili grupa poznata pod pseudonimom Satoshi Nakamoto, oko 2008. godine.
Niko ne zna Satoshijev identitet, a koliko znamo, oni su nestali i o njima se godinama ništa nije čulo.
11.februara 2009. godine, Satoshi je pisao o ranoj verziji Bitcoin-a na mrežnom forumu za cypherpunkere, ljude koji rade na tehnologiji kriptografije i koji su zabrinuti za privatnost i slobodu pojedinca.
Iako ovo nije prvo zvanično objavljivanje Bitcoin-a, sadrži dobar rezime Satoshi-jevih motiva.
Razvio sam novi P2P sistem e-keša otvorenog koda pod nazivom Bitcoin. Potpuno je decentralizovan, bez centralnog servera ili pouzdanih stranki, jer se sve zasniva na kripto dokazima umesto na poverenju. […]
Osnovni problem konvencionalne valute je potpuno poverenje koje je potrebno za njeno funkcionisanje. Centralnoj banci se mora verovati da neće devalvirati valutu, ali istorija tradicionalnih valuta je puna primera kršenja tog poverenja. Bankama se mora verovati da drže naš novac i prenose ga elektronskim putem, ali one ga daju u talasima kreditnih balona sa delićem rezerve. Moramo im verovati sa našom privatnošću, verovati im da neće dozvoliti da kradljivci identiteta pokradu naše račune. Njihovi ogromni režijski troškovi onemogućavaju mikro plaćanja.
Generaciju ranije, višekorisnički time-sharing računarski sistemi imali su sličan problem. Pre pojave jake enkripcije, korisnici su morali da imaju pouzdanje u zaštitu lozinkom kako bi zaštitili svoje fajlove […]
Tada je jaka enkripcija postala dostupna širokim masama i više nije bilo potrebno poverenje. Podaci bi se mogli osigurati na način koji je fizički bio nemoguć za pristup drugima, bez obzira iz kog razloga, bez obzira koliko je dobar izgovor, bez obzira na sve.
Vreme je da imamo istu stvar za novac. Uz e-valutu zasnovanu na kriptografskom dokazu, bez potrebe da verujete posredniku treće strane, novac može biti siguran i transakcije mogu biti izvršene bez napora. […]
Rešenje Bitcoin-a je korišćenje peer-to-peer mreže za proveru dvostruke potrošnje. Ukratko, mreža radi poput distribuiranog servera vremenskih žigova, obeležavajući prvu transakciju koja je potrošila novčić. Potrebna je prednost prirode informacije koju je lako širiti, ali je teško ugušiti. Za detalje o tome kako to funkcioniše, pogledajte članak o dizajnu na bitcoin.org
Satoshi Nakamoto
Koje Probleme Rešava Bitcoin?
Razdvojimo neke od Satoshi-jevih postova kako bismo uvideli razloge njegove motivacije.
„Razvio sam novi P2P sistem e-keša otvorenog koda.“
P2P je skraćenica za peer to peer i ukazuje na sistem u kojem jedna osoba može da komunicira sa drugom bez ikoga u sredini, kao medjusobno jednaki.
Možete se setiti P2P tehnologija za razmenu datoteka poput Napster-a, Kazaa-e i BitTorrrent-a, koje su prve omogućile ljudima da dele muziku i filmove bez posrednika.
Satoshi je dizajnirao Bitcoin kako bi omogućio ljudima da razmenjuju e-keš, elektronski keš, bez prolaska preko posrednika na približno isti način.
Softver je otvorenog koda, što znači da svako može videti kako funkcioniše i doprineti tome.
Ne treba da verujemo ni u šta što je Satoshi napisao u svom postu o tome kako softver radi.
Možemo pogledati kod i sami proveriti kako to funkcioniše. Štaviše, možemo promeniti funkcionalnost sistema promenom koda.
„Potpuno je decentralizovan, bez centralnog servera ili pouzdanih stranki …“
Satoshi napominje da je sistem decentralizovan kako bi se razlikovao od sistema koji imaju centralnu kontrolu.
Prethodne pokušaje stvaranja digitalne gotovine poput DigiCash-a od strane Davida Chaum-a podržavao je centralni server, računar ili skup računara koji je bio odgovoran za izdavanje i verifikaciju plaćanja pod kontrolom jedne korporacije.
Takve, centralno kontrolisane privatne šeme novca, bile su osuđene na propast; ljudi se ne mogu osloniti na novac koji može nestati kada kompanija prestane sa poslovanjem, bude hakovana, pretrpi pad servera ili je zatvori vlada.
Bitcoin održava mreža pojedinaca i kompanija širom sveta.
Da bi se Bitcoin isključio, bilo bi potrebno isključiti desetine do stotine hiljada računara širom sveta u isto vreme, zauvek, od kojih su mnogi na nepoznatim lokacijama.
Bila bi to beznadežna igra, jer bi svaki napad ove prirode jednostavno podstakao stvaranje novih Bitcoin čvorova ili računara na mreži.
„… sve se zasniva na kripto dokazima umesto na poverenju“
Internet, a u stvari i većina savremenih računarskih sistema, izgrađeni su na kriptografiji, metodi prikrivanja informacija, tako da je može dekodirati samo primalac informacije.
Kako se Bitcoin oslobađa potrebe za poverenjem? Umesto da verujemo nekome ko kaže „Ja sam Alisa“ ili „Imam 10 $ na računu“, možemo koristiti kriptografsku matematiku da bismo izneli iste činjenice na način koji je vrlo lako verifikovati od strane primaoca dokaza ali ga je nemoguće falsifikovati.
Bitcoin u svom dizajnu koristi kriptografsku matematiku kako bi učesnicima omogućio da provere ponašanje svih ostalih učesnika, bez poverenja u bilo koju centralnu stranku.
„Moramo im verovati [bankama] sa našom privatnošću, verovati im da neće dozvoliti da kradljivci identiteta pokradu naše račune“
Za razliku od korišćenja vašeg bankovnog računa, sistema digitalnog plaćanja ili kreditne kartice, Bitcoin omogućava dvema stranama da obavljaju transakcije bez davanje bilo kakvih ličnih podataka.
Centralizovana skladišta potrošačkih podataka koji se čuvaju u bankama, kompanijama sa kreditnim karticama, procesorima plaćanja i vladama, predstavljaju pravu poslasticu za hakere.
Kao dokaz Satoshi-jeve poente služi primer iz 2017. godine kada je Equifax masovono kompromitovan, kada su hakeri ukrali identifikacione i finansijske podatke za više od 140 miliona ljudi.
Bitcoin odvaja finansijske transakcije od stvarnih identiteta.
Na kraju krajeva, kada nekome damo fizički novac, on nema potrebu da zna ko smo, niti treba da brinemo da će nakon naše razmene moći da iskoristi neke informacije koje smo mu dali da ukrade još našeg novca.
Zašto ne bismo očekivali isto, ili čak i bolje, od digitalnog novca?
„Centralnoj banci se mora verovati da neće devalvirati valutu, ali istorija tradicionalnih valuta je puna primera kršenja tog poverenja.“
Pojam tradicionalna valuta, odnosi se na valutu izdatu od strane vlade i centralne banke, koju vlada proglašava zakonskim sredstvom plaćanja.
Istorijski, novac je nastao od stvari koje je bilo teško proizvesti, koje su bile lake za proveravanje i transport, poput školjki, staklenih perli, srebra i zlata.
Kad god bi se nešto koristilo kao novac, postojalo je iskušenje da se stvori više toga.
Ako bi neko pronašao vrhunsku tehnologiju za brzo stvaranje velike količine nečega, ta stvar bi izgubila vrednost.
Evropski naseljenici uspeli su da liše afrički kontinent bogatstva trgujući staklenim perlicama koje su se lako proizvodile za ljudske robove.
Isto se dogodilo sa američkim indijancima, kada su kolonisti otkrili način brze proizvodnje vampum školjki, koje su starosedeoci smatrali retkim.
Vremenom, širom sveta ljudi su shvatili da je samo zlato dovoljno retko da deluje kao novac, bez straha da bi neko drugi mogao da ga stvori u velikim količinama.
Polako smo prešli sa svetske ekonomije koja je koristila zlato kao novac na onu gde su banke izdavale papirne sertifikate kao dokaz posedovanja tog zlata.
Nixon je okončao međunarodnu konvertibilnost američkog dolara u zlato 1971. godine, privremenim rešenjem, koje je ubrzo postalo trajno.
Kraj zlatnog standarda omogućio je vladama i centralnim bankama da imaju punu dozvolu da povećavaju novčanu masu po svojoj volji, razredjujući vrednost svake novčanice u opticaju, poznatije kao umanjenje vrednosti.
Iako je izdata od strane vlade, suštinska tradicionalna valuta je novac koji svi znamo i svakodnevno koristimo, ipak je relativno novo iskustvo u opsegu svetske istorije.
Moramo verovati našim vladama da ne zloupotrebljavaju njegovo štamparije, i ne treba nam puno muke da nadjemo primere kršenja tog poverenja.
U autokratskim i centralno planiranim režimima gde vlada ima prst direktno na mašini za novac, kao što je Venecuela, valuta je postala gotovo bezvredna.
Venecuelanski Bolivar prešao je sa 2 bolivara za 1 američki dolar, koliko je vredeo 2009. godine, na 250.000 bolivara za 1 američki dolar 2019. godine.
Pogledajte koliko novčanica je bilo potrebno za kupovinu piletine u Venecueli posle hiperinflacije.
Satoshi je želeo da ponudi alternativu tradicionalnoj valuti čija se ponuda uvek nepredvidivo širi.
Da bi sprečilo umanjenje vrednosti, Satoshi je dizajnirao novčani sistem gde je zaliha bila fiksna i izdavana po predvidljivoj i nepromenjivoj stopi.
Postojaće samo 21 milion Bitcoin-a.
Međutim, svaki Bitcoin se može podeliti na 100 miliona jedinica koje se sada nazivaju satoshis (sats-ovi), što će činiti ukupno 2,1 kvadriliona satoshi-a u opticaju oko 2140. godine.
Pre Bitcoin-a nije bilo moguće sprečiti beskrajnu reprodukciju digitalnih sredstava.
Kopirati digitalnu knjigu, audio datoteku ili video zapis i poslati ga prijatelju, je jeftino i lako.
Jedini izuzeci od toga su digitalna sredstva koja kontrolišu posrednici.
Na primer, kada iznajmite film sa iTunes-a, možete ga gledati na vašem uređaju samo zato što iTunes kontroliše distribuciju tog filma i može ga zaustaviti nakon perioda njegovog iznajmljivanja.
Slično tome, vaša banka kontroliše vaš digitalni novac. Zadatak banke je da vodi evidenciju koliko novca imate.
Ako ga prenesete nekom drugom, oni će odobriti ili odbiti takav prenos.
Bitcoin je prvi digitalni sistem koji sprovodi oskudicu bez posrednika i prvo je sredstvo poznato čovečanstvu čija je nepromenljiva ponuda i raspored izdavanja poznat unapred.
Ni plemeniti metali poput zlata nemaju ovo svojstvo, jer uvek možemo iskopati sve više i više zlata ukoliko je to isplativo.
Zamislite da otkrijemo asteroid koji sadrži deset puta više zlata nego što ga imamo na zemlji.
Šta bi se dogodilo sa cenom zlata uzimajući u obzir tako obilnu ponudu? Bitcoin je imun na takva otkrića i manipulisanje nabavkom.
Jednostavno je nemoguće proizvesti više od toga (21 miliona).
„Podaci bi se mogli osigurati na način koji je fizički bio nemoguć za pristup drugima, bez obzira iz kog razloga, bez obzira koliko je dobar izgovor, bez obzira na sve. […] Vreme je da imamo istu stvar za novac “
Naše trenutne metode obezbeđivanja novca, poput stavljanja u banku, oslanjaju se na poverenje nekome drugom da će obaviti taj posao.
Poverenje u takvog posrednika ne zahteva samo sigurnost da on neće učiniti nešto zlonamerno ili glupo, već i da vlada neće zapleniti ili zamrznuti vaša sredstva vršeći pritisak na ovog posrednika.
Međutim, videli smo bezbroj puta da vlade mogu, i zaista uskraćuju pristup novcu kada se osećaju ugroženo.
Nekom ko živi u Sjedinjenim Državama ili nekoj drugoj visoko regulisanoj ekonomiji možda zvuči glupo da razmišlja da se probudi sa oduzetim novcem, ali to se događa stalno.
PayPal mi je zamrzao sredstva jednostavno zato par meseci nisam koristio svoj račun.
Trebalo mi je više od nedelju dana da vratim pristup „svom“ novcu.
Srećan sam što živim u Europi, gde bih se bar mogao nadati da ću potražiti neko pravno rešenje ako mi PayPal zamrzne sredstva i gde imam osnovno poverenje da moja vlada i banka neće ukrasti moj novac.
Mnogo gore stvari su se dogodile, i trenutno se dešavaju, u zemljama sa manje slobode.
Banke su se zatvorile tokom kolapsa valuta u Grčkoj.
Banke na Kipru su koristile kaucije da konfiskuju sredstva od svojih klijenata.
Indijska vlada je proglasila određene novčanice bezvrednim.
Bivši SSSR, u kojem sam odrastao, imao je ekonomiju pod kontrolom vlade što je dovelo do ogromnih nestašica robe.
Bilo je nezakonito posedovati strane valute kao što je američki dolar.
Kada smo poželeli da odemo, mojoj porodici je bilo dozvoljeno da zameni samo ograničenu količinu novca po osobi za američke dolare po zvaničnom kursu koji je bio u velikoj meri različit od pravog kursa slobodnog tržišta.
U stvari, vlada nam je oduzela ono malo bogatstva koje smo imali koristeći gvozdeni stisak na ekonomiji i kretanju kapitala.
Autokratske zemlje imaju tendenciju da sprovode strogu ekonomsku kontrolu, sprečavajući ljude da na slobodnom tržištu povuku svoj novac iz banaka, iznesu ga iz zemlje ili da ga razmene u ne još uvek bezvredne valute poput američkog dolara.
To omogućava vladinoj slobodnoj vladavini da primeni sulude ekonomske eksperimente poput socijalističkog sistema SSSR-a.
Bitcoin se ne oslanja na poverenje u treću stranu da bi osigurao vaš novac.
Umesto toga, Bitcoin onemogućava drugima pristup vašim novčićima bez jedinstvenog ključa koji imate samo vi, bez obzira iz kog razloga, bez obzira koliko je dobar izgovor, bez obzira na sve.
Držeći Bitcoin, držite ključeve sopstvene finansijske slobode. Bitcoin razdvaja novac i državu
„Rešenje Bitcoin-a je korišćenje peer-to-peer mreže za proveru dvostruke potrošnje […] poput distribuiranog servera vremenskih žigova, obeležavajući prvu transakciju koja je potrošila novčić“
Mreža se odnosi na ideju da je gomila računara povezana i da mogu međusobno slati poruke.
Reč distribuirano znači da ne postoji centralna stranka koja kontroliše, već da svi učesnici koordiniraju medjusobno kako bi mreža bila uspešna.
U sistemu bez centralne kontrole, bitno je znati da niko ne vara. Ideja dvostruke potrošnje odnosi se na mogućnost trošenja istog novca dva puta.
Fizički novac odlazi iz vaše ruke kad ga potrošite. Međutim, digitalne transakcije se mogu kopirati baš kao muzika ili filmovi.
Kada novac šaljete preko banke, oni se pobrinu da isti novac ne možete da prebacujete dva puta.
U sistemu bez centralne kontrole potreban nam je način da sprečimo ovu vrstu dvostruke potrošnje, koja je u suštini ista kao i falsifikovanje novca.
Satoshi opisuje da učesnici u Bitcoin mreži rade zajedno kako bi vremenski označili (doveli u red) transakcije kako bismo znali šta je bilo prvo.
Zbog toga možemo odbiti sve buduće pokušaje trošenja istog novca.
Satoshi se uhvatio u koštac sa nekoliko zanimljivih tehničkih problema kako bi rešio probleme privatnosti, uništavanja vrednosti i centralne kontrole u trenutnim monetarnim sistemima.
Na kraju je stvorio peer to peer mrežu kojoj se svako mogao pridružiti bez otkrivanja svog identiteta ili potrebe da veruje bilo kom drugom učesniku.
Kako se Bitcoin razvijao u poslednjoj deceniji?
Doprinosi izvornom kodu Bitcoina
Kada je Bitcoin pokrenut, samo nekolicina ljudi ga je koristila i pokrenula Bitcoin softver na svojim računarima za napajanje Bitcoin mreže.
Većina ljudi u to vreme mislila je da je to šala ili da će se otkriti ozbiljni nedostaci u dizajnu sistema koji će ga učiniti neizvodljivim.
Vremenom se mreži pridružilo sve više ljudi koji su pomoću svojih računara dodali sigurnost mreži.
Ljudi su počeli da menjaju Bitcoin-e za robu i usluge, dajući mu stvarnu vrednost. Pojavile su se menjačnice valuta koje su menjale Bitcoin-e za gotovo sve tradicionalne valute na svetu.
Deset godina nakon izuma, Bitcoin koriste milioni ljudi sa desetinama do stotinama hiljada čvorova koji pokreću besplatni Bitcoin softver, koji se razvija od strane stotina dobrovoljaca i kompanija širom sveta.
Bitcoin mreža je porasla kako bi obezbedila vrednost veću od stotine biliona dolara.
Računari koji učestvuju u zaštiti Bitcoin mreže poznati su kao rudari/majneri.
Oni rade u industrijskim operacijama širom sveta, ulažući milione dolara u specijalni rudarski hardver koji radi samo jedno: pobrinuti se da je Bitcoin najsigurnija mreža na planeti.
Rudari troše električnu energiju kako bi transakcije Bitcoin-a učinile sigurnim od modifikacija. Budući da se rudari međusobno takmiče za oskudan broj Bitcoin-a proizvedenih dnevno, oni uvek moraju da pronalaze najjeftinije izvore energije na planeti da bi ostali profitabilni.
Rudari rade na različitim mestima, od hidroelektrana u dalekim krajevima Kine do vetroparkova u Teksasu, do kanadskih naftnih polja koja proizvode gas koji bi u suprotnom bio odzračen ili spaljen u atmosferi.
Iako je Bitcoin popularna tema i o njemu se često raspravlja u medijima, procenjujemo da je samo nekoliko miliona ljudi na svetu počelo da redovno štedi Bitcoin.
Za mnoge ljude, posebno za one koji nikada nisu živeli pod represivnim režimima, ovaj izum novog oblika digitalnog novca izvan kontrole vlade može biti veoma izazovan za razumevanje i prihvatanje.
Zato sam ja ovde. Želim da vam pomognem da razumete Bitcoin i budete gospodar svoje budućnosti!

Bitcoin čini da štednja novca bude kul – i praktična – ponovo. Ovaj članak objašnjava kako i zašto.
Šta je Bitcoin?
Bitcoin se naziva digitalno zlato, mašina za istinu, blockchain, peer to peer mreža čvorova, energetski ponor i još mnogo toga. Bitcoin je, u stvari, sve ovo. Međutim, ova objašnjenja su često toliko tehnička i suvoparna, da bi većina ljudi radije gledala kako trava raste. Što je najvažnije, ova objašnjenja ne pokazuju kako Bitcoin ima bilo kakve koristi za vas.
iPod nije postao kulturološka senzacija jer ga je Apple nazvao „prenosnim digitalnim medijskim uređajem“. Postao je senzacija jer su ga zvali “1,000 pesama u vašem džepu.”
Ne zanima vas šta je Bitcoin. Vas zanima šta on može da učini za vas.
Baš kao i Internet, vaš auto, vaš telefon, kao i mnogi drugi uređaji i sistemi koje svakodnevno koristite, vi ne treba da znate šta je Bitcoin ili kako to funkcioniše da biste razumeli šta on može da učini za vas.
Šta Bitcoin može da učini za vas?
Bitcoin može da sačuva vaš teško zarađeni novac.
Bitcoin je stekao veliku pažnju u 2017. i 2018. godini zbog svoje spekulativne upotrebe. Mnogi ljudi su ga kupili nadajući se da će se obogatiti. Cena je naglo porasla, a zatim se srušila. Ovo nije bio prvi put da je Bitcoin uradio to. Međutim, niko nikada nije izgubio novac držeći bitcoin duže od 3,5 godine – ćak i ako je kupio na apsolutnim vrhovima.
Zašto Bitcoin konstantno raste? Ljudi počinju da shvataju koliko je Bitcoin moćan, kao način uštede novca u svetu u kojem je ’novac’ poput dolara, eura i drugih nacionalnih valuta dizajniran da gubi vrednost.
Ovo čini Bitcoin odličnom opcijom za štednju novca na nekoliko godina ili više. Bitcoin je bolji od štednje novca u dolarima, akcijama, nekretninama, pa čak i u zlatu.
Zato pokušajte da zaboravite na trenutak na razumevanje blockchaina, digitalne valute, kriptografije, seed fraza, novčanika, rudarstva i svih ostalih nerazumljivih termina. Za sada, razgovarajmo o tome zašto ljudi kupuju Bitcoin: razlog je prostiji nego što vi mislite.
Zašto ljudi kupuju Bitcoin?
Naravno, svako ima svoj razlog za kupovinu Bitcoin-a. Jedan od razloga, koji verovatno često čujete, je taj što mu vrednost raste. Ljudi žele da se obogate. Uskoče kao spekulanti, krenu u vožnju i najverovatnije ih prodaju ubrzo nakon kupovine.
Međutim, čak i kada cena krene naglo prema gore i strmoglavo padne nazad, mnogi ljudi ostanu i nakon tog pada. Otkud mi to znamo? Broj aktivnih novčanika dnevno, koji je otprilike sličan broju korisnika Bitcoin-a, nastavlja da raste. Takođe, nakon svakog balona u istoriji Bitcoin-a, cena se nikada ne vraća na svoju cenu pre balona. Uvek ostane malo višlja. Bitcoin se penje, a svaka masovna spekulativna serija dovodi sve više i više ljudi.
Broj aktivnih Bitcoin novčanika neprekidno raste
„Aktivna adresa“ znači da je neko tog dana poslao Bitcoin transakciju. Donji grafikon je na logaritamskoj skali.

Cena Bitcoina se neprestano penje
Kroz istoriju Bitcoin-a možemo videti divlje kolebanje cena, ali nakon svakog balona, cena se ostaje višlja nego pre. Ovo je cena Bitcoin-a na logaritamskoj skali.
Izvor: Glassnode
To pokazuje da se ljudi zadržavaju: potražnja za Bitcoin-om se povećava. Da je svaki masovni rast cena bio samo balon koji su iscenirali prevaranti koji žele brzo da se obogate, cena bi se vratila na nivo pre balona. To se dogodilo sa lalama, ali ne i sa Bitcoin-om.
I zašto se onda cena Bitcoin-a stalno povećava? Sve veći broj ljudi čuva Bitcoin dugoročno – oni razumeju šta Bitcoin može učiniti za njihovu štednju.
Zašto ljudi štede svoj novac u Bitcoin-u umesto na štednim računima, kućama, deonicama ili zlatu? Hajde da pogledajmo sve te metode štednje, i zatim da ih uporedimo sa Bitcoin-om.
Da li je vaš novac siguran u dolarima, kućama, akcijama ili zlatu?
Tokom mnogo godina, to su bile pristojne opcije za štednju. Međutim, sistem koji podržava vrednost svega ovoga je u krizi.
Dolari, Euri, Dinari
Dolari i sve ostale „tradicionalne“ valute koje proizvode vlade, stvorene su da izgube vrednost kroz inflaciju. Banke i tradicionalni monetarni sistem uzrokuju inflaciju stalnim stvaranjem i distribucijom novog novca. Kada Američke Federalne Rezerve objave ciljanu stopu od 2% inflacije, to znači da žele da vaš novac svake godine izgubi 2% od svoje vrednosti. Čak i sa inflacijom od samo 2%, vaša štednja u dolarima izgubiće polovinu vrednosti tokom 40-godišnjeg radnog veka.
Izveštena inflacija se danas opasno povečava, uprkos rastućem „buretu sa barutom“ koji bi mogao da explodira i dovede do masivne hiperinflacije. Što je više valute u opticaju, to je više baruta u buretu.
Naše vlade su ekonomiju napunile valutama da bankarski sistem ne bi propao nakon finansijske krize koja se dogodila 2008. godine. Od tada je većina glavnih centralnih banaka postavila vrlo niske kamatne stope, što pojedincima i korporacijama omogućava dobijanje jeftinijih kredita. To znači da mnogi pojedinci i korporacije podižu ogromne kredite i koriste ih za kupovinu druge imovine poput deonica, umetničkih dela i nekretnina. Sve ovo pozajmljivanje znači da stvaramo tone novog novca i stavljamo ga u opticaj.
Računi za podsticaje (stimulus bills) COVID-19 za 2020. godinu unose trilione u sistem. Ovoliko stvaranje valuta na kraju dovodi do inflacije – velikog gubitka u vrednosti valute.
Količina američkog dolara u opticaju gotovo se udvostručila od marta 2020. godine. Izvor
Računi za podsticaje su bez presedana, toliko da je neko izmislio meme da opiše ovu situaciju.
Resurs koji vlade mogu da naprave u većem broju da bi platile svoje račune? Ne zvuči kao dobro mesto za štednju novca.
Kuće
Kuće su tokom prošlog veka bile pristojan način štednje novca. Međutim, pad cena nekretnina 2007. godine doveo je do toga da su mnogi vlasnici kuća izgubili svu ušteđevinu.
Danas su kuće gotovo nepristupačne za prosečnog čoveka. Jedan od načina da se ovo izmeri je koliko godišnjih zarada treba prosečnom čoveku da zaradi ekvivalent vrednosti prosečne kuće. Prema CityLab-u, publikaciji Bloomberg-a koja pokriva gradove, porodica može da priuštiti određenu kuću ako košta manje od 2,6 godišnjih prihoda domaćinstva te porodice.
Međutim, prema RZS (Republički zavod za statistiku) prosečan prihod porodičnog domaćinstva u Srbiji iznosi oko 570 EUR mesečno ili otprilike 7.000 EUR godišnje. Nažalost, samo najjeftinija područja van gradova imaju srednje cene kuća od oko 2,6 prosečnih godišnjih prihoda domaćinstva. U većim gradovima poput Beograda i Novog Sada srednja cena kuće je veća od 10 prosečnih godišnjih prihoda jednog domaćinstva.
Ako nekako možete sebi da priuštite kuću, ona bi mogla biti pristojna zaliha vrednosti. Dokle god ne doživimo još jedan krah i izvršitelji zaplene ovu imovinu mnogim vlasnicima kuća.
Akcije
Berza je u prošlosti takođe dobro poslovala. Međutim, sporo i stabilno povećanje tržišta događa se u dosadnom, predvidljivom svetu. Svakog dana vidimo sve manje toga. Nakon ubrzanja korona virusa, videli smo smo najbrži pad američke berze u istoriji od 25% – brži od Velike depresije.
Neki se odlučuju za ulaganje u obveznice i drugu finansijsku imovinu, ali ’prinosi’ za tu imovinu – procenat kamate zarađene na imovinu iz godine u godinu – stalno opada. Sve veći broj odredjenih imovina ima čak i negativne prinose, što znači da posedovanje te imovine košta! Ovo je veliki problem za sve koji se oslanjaju na penziju. Plus, s obzirom na to da su akcije denominovane u tradicionalnim valutama poput dolara i evra, inflacija pojede prinos koji investitor dobije.
Najgore od svega je to što ti isti ekonomski krahovi koji uzrokuju masovna otpuštanja i teško tržište rada takođe znače i nagli pad cena akcija. Čuvanje ušteđevine u akcijama može značiti i gubitak štednje i gubitak posla zbog recesije. Teška vremena mogu da vas prisile da svoje akcije prodate po vrlo malim cenama samo da biste platili svoje račune.
A to nije baš siguran način štednje novca.
Zlato
Vrednost zlata neprekidno se povećavala tokom 5000 godina, obično padajući onda kada berza obećava jače prinose.
Evidencija vrednosti zlata je solidna. Međutim, zlato nosi i druge rizike. Većina ljudi poseduje zlato na papiru. Oni fizički ne poseduju zlato, već ga njihova banka čuva za njih. Zbog toga je zlato veoma podložno konfiskaciji od strane vlade.
Zašto bi vlada konfiskovala nečije zlato, a kamoli u demokratskoj zemlji u „slobodnom svetu“? Ali to se dešavalo i ranije. 1933. godine Izvršnom Naredbom 6102, predsednik Roosevelt naredio je svim Amerikancima da prodaju svoje zlato vladi u zamenu za papirne dolare. Vlada je iskoristila pretnju zatvorom za prikupljanje zlata u fizičkom obliku. Znali su da se zlato više poštuje kao zaliha vrednosti širom sveta od papirnih dolara.
Ako posedujete svoje zlato na nekoj od aplikacija za trgovanje akcijama, možete se kladiti da će vam ga država oduzeti ako joj zatreba. Čak i ako posedujete fizičko zlato, onda ga izlažete mogućnosti krađe – od strane kriminalca ili vaše vlade.
Vaša uštedjevina nije bezbedna.
Rast cena svih gore navedenih sredstava zavisi od našeg trenutnog političkog i ekonomskog sistema koji se nastavlja kao i tokom proteklih 100 godina. Međutim, danas vidimo ogromne pukotine u ovom sistemu.
Sistem ne funkcioniše dobro za većinu ljudi.
Od 1971. plate većine američkih radnika nisu rasle. S druge strane, bogatstvo koje imaju najbogatiji u društvu nalazi se na nivoima koji nisu viđeni više od 80 godina. U međuvremenu, ljudi sve manje i manje veruju institucijama poput banaka i vlada.
CBPP Nejednakost Bogatstva Tokom Vremena
Širom sveta možemo videti dokaze o slamanju sistema kroz politički ekstremizam: izbor Trampa i drugih ekstremističkih desničarskih kandidata, Bregzit, pokret Occupy, popularizacija koncepta univerzalnog osnovnog dohotka, povratak pojma „socijalizam“ nazad u modu. Ljudi na svim delovima političkog i društvenog spektra osećaju problematična vremena i posežu za sve radikalnijim rešenjima.
Šta je bolje za štednju od dolara, kuća i akcija?
Pa kako ljudi mogu da štede novac u ovim teškim vremenima? Ili ne koriste tradicionalne valute, ili kupuju sredstva koja će zadržati vrednost u teškim vremenima.
Bitcoin ima najviše potencijala da zadrži vrednost kroz politička i ekonomska previranja od bilo koje druge imovine. Na tom putu će biti rupa na kojima će se rušiti ili pumpati, međutim, njegova svojstva čine ga takvim da će verovatno preživeti previranja kada druga imovina ne bude to mogla.
Šta Bitcoin čini drugačijim?
Bitcoini su retki.
Proces ‘rudarenja’ bitcoin-a, proizvodnju bitcoin-a čini veoma skupom, a Bitcoin protokol ograničava ukupan broj bitcoin-a na 21 milion novčića. To čini Bitcoin imunim na nagle poraste ponude. Ovo se veoma razlikuje od tradicionalnih valuta, koje vlade mogu da štampaju sve više kad god one to požele. Zapamtite, povećanje ponude vrši veliki pritisak na vrednost valute.
Bitcoini nemaju drugu ugovornu stranu.
Bitcoin se takođe razlikuje od imovine kao što su obveznice, akcije i kuće, jer mu nedostaje druga ugovorna strana. Druge ugovorne strane su drugi subjekti uključeni u vrednost sredstva, koji to sredstvo mogu obezvrediti ili vam ga uzeti. Ako imate hipoteku na svojoj kući, banka je druga ugovorna strana. Kada sledeći put dođe do velikog finansijskog kraha, banka vam može oduzeti kuću. Kompanije su kvazi-ugovorne strane akcijama i obveznicama, jer mogu da počnu da donose loše odluke koje utiču na njihovu cenu akcija ili na „neizvršenje“ duga (da ga ne vraćaju vama ili drugim poveriocima). Bitcoin nema ovih problema.
Bitcoin je pristupačan.
Svako sa 5 eura i mobilnim telefonom može da kupi i poseduje mali deo bitcoin-a. Važno je da znate da ne morate da kupite ceo bitcoin. Bitcoin-i su deljivi do 100-milionite jedinice, tako da možete da kupite Bitcoin u vrednosti od samo nekoliko eura. Neuporedivo lakše nego kupovina kuće, zlata ili akcija!
Bitcoin se ne može konfiskovati.
Banke drže većinu vaših eura, zlata i akcija za vas. Većina ljudi u razvijenom svetu veruje bankama, jer većina ljudi koji žive u današnje vreme nikada nije doživela konfiskaciju imovine ili ’šišanje’ od strane banaka ili vlada. Nažalost, postoji presedan za konfiskaciju imovine čak i u demokratskim zemljama sa snažnom vladavinom prava.
Kada vlada konfiskuje imovinu, ona obično ubedi javnost da će je menjati za imovinu jednake vrednosti. U SAD-u 1930-ih, vlada je davala dolare vlasnicima zlata. Vlada je znala da uvek može da odštampa još više dolara, ali da ne može da napravi više zlata. Na Kipru 2012. godine, jedna propala banka je svojim klijentima dala deonice banke da pokrije dolare klijenata koje je banka trebala da ima. I dolari i deonice su strmoglavo opali u odnosu na imovinu koja je uzeta od ovih ljudi.
Doći do bitcoin-a koji ljudi poseduju, biće mnogo teže jer se bitcoin-i mogu čuvati u novčaniku koji ne poseduje neka treća strana, a vi možete čak i da zapamtite privatne ključeve do vašeg bitcoin-a u glavi.
Bitcoin je za štednju.
Bitcoin se polako pokazuje kao najbolja opcija za dugoročnu štednju novca, posebno s obzirom na današnju ekonomsku klimu. Posedovanje čak i malog dela, je polisa osiguranja koja se isplati ako svet i dalje nastavi da ludi. Cena Bitcoin-a u dolarima može divlje da varira u roku od godinu ili dve, ali tokom 3+ godine skoro svi vide slične ili više cene od trenutka kada su ga kupili. U stvari, doslovno niko nije izgubio novac čuvajući Bitcoin duže od 3,5 godine – čak i ako je kupio BTC na apsolutnim vrhovima tržišta.
Imajte na umu da nakon ove tačke ti ljudi više nikada nisu videli rizik od gubitka. Cena se nikada nije smanjila niže od najviše cene u prethodnom ciklusu.
Po čemu se Bitcoin razlikuje od ostalih valuta?
Bitcoin funkcioniše tako dobro kao način štednje zbog svog neobičnog dizajna, koji ga čini drugačijim od bilo kog drugog oblika novca koji je postojao pre njega. Bitcoin je digitalna valuta, prvi i verovatno jedini primer valute koja ima ograničenu ponudu dok radi na otvorenom, decentralizovanom sistemu. Vlade strogo kontrolišu valute koje danas koristimo, poput dolara i eura, i proizvode ih za finansiranje ratova i dugova. Korisnici Bitcoin-a – poput vas – kontrolišu Bitcoin protokol.
Evo šta Bitcoin razlikuje od dolara, eura i drugih valuta:
Bitcoin je otvoren sistem.
Svako može da odluči da se pridruži Bitcoin mreži i primeni pravila softverskog protokola, što je dovelo do vrlo decentralizovanog sistema u kojem nijedan pojedinac ili entitet ne može da blokira transakciju, zamrzne sredstva ili da ukrade od druge osobe.Današnji savremeni bankarski sistem se uveliko razlikuje. Nekoliko banaka je dobilo poverenje da gotovo sve valute, akcije i druge vredne predmete čuvaju na “sigurnom” za svoje klijente. Da biste postali banka, potrebni su vam milioni dolara i neverovatne količine političkog uticaja. Da biste pokrenuli Bitcoin čvor i postali „svoja banka“, potrebno vam je nekoliko stotina dolara i jedno slobodno popodne.
Tako izgleda Bitcoin čvor – Node MyNode čvor vam omogućava da postanete svoja banka za samo nekoliko minuta.
Bitcoin ima ograničenu ponudu.
Softverski protokol otvorenog koda koji upravlja Bitcoin sistemom ograničava broj novih bitcoin-a koji se mogu stvoriti tokom vremena, sa ograničenjem od ukupno 21.000.000 bitcoin-a. S druge strane, valute koje danas koristimo imaju neograničenu ponudu. Istorija i sadašnje odluke centralnih banaka govore nam da će vlade uvek štampati sve više i više valuta, sve dok valuta ne bude bezvredna. Sve ovo štampanje uzrokuje inflaciju, što pravi štetu običnim radnim ljudima i štedišama.
Tradicionalne valute su dizajnirane tako da opadaju vremenom. Svaki put kada centralna banka kaže da cilja određenu stopu inflacije, oni ustvari kažu da žele da vaš novac svake godine izgubi određeni procenat svoje vrednosti.
Bitcoin-ova ograničena ponuda znači da je on tako dizajniran da raste vremenom kako se potražnja za njim povećava.
Bitcoin putuje oko sveta za nekoliko minuta.
Svako može da pošalje bitcoin-e za nekoliko minuta širom sveta, bez obzira na granice, banke i vlade. Potrebno je manje od minuta da se transakcija pojavi na novčaniku primaoca i oko 60 minuta da se transakcija u potpunosti „obračuna“, tako da primaoc može da bude siguran da su primljeni bitcoin-i sada njegovi (6 konfirmacija bloka). Slanje drugih valuta širom sveta traje danima ili čak mesecima ako se šalju milionski iznosi, a podrazumeva i visoke naknade.
Neke vlade i novinari tvrde da ova sloboda putovanja koju pruža Bitcoin pomaže kriminalcima i teroristima. Međutim, transakciju Bitcoin-a je lakše pratiti nego većinu transakcija u dolarima ili eurima.
Bitcoin se može čuvati na “USB-u”.
Dizajn Bitcoin-a je takav da vam treba samo da čuvate privatni ključ do svojih ‘bitcoin’ adresa (poput lozinke do bankovnih računa) da biste pristupili svojim bitcoin-ima odakle god poželite. Ovaj privatni ključ možete da sačuvate na disku ili na papiru u obliku 12 ili 24 reči na engleskom jeziku. Kao rezultat toga, možete da držite Bitcoin-e vredne milione dolara u svojoj šaci.
Sve ostale valute danas možete ili da strpate u svoj dušek ili da ih poverite banci na čuvanje. Za većinu ljudi koji žive u razvijenom svetu, i koji ne osporavaju autoritet i poverenje u banku, ovo deluje sasvim dobro. Međutim, oni kojima je potrebno da pobegnu od ugnjetavačke vlade ili koji naljute pogrešne ljude, ne mogu verovati bankama. Za njih je sposobnost da nose svoju ušteđevinu bez potrebe za ogromnim koferom neprocenjiva. Čak i ako ne živite na mestu poput ovog, cena Bitcoin-a se i dalje povećava kada ih neko kome oni trebaju kupi.
Kako Bitcoin spašava svet?
Bitcoin, kao ultimativni način štednje, je cakum pakum, ali da li on pomaže u poboljšanju sveta u celini?
Kao što ćete početi da shvatate, ulazeći sve dublje i u druge sadržaje na ovoj stranici, mnogi temeljni delovi našeg današnjeg monetarnog sistema i ekonomije su duboko slomljeni. Međutim, oni koji upravljaju imaju korist od ovakvih sistema, pa se on verovatno neće promeniti bez revolucije ili mirnog svrgavanja od strane naroda. Bitcoin predstavlja novi sistem, sa nekoliko glavnih prednosti:
- Bitcoin popravlja novac, koji je milenijumima služio kao važan alat za rast i poboljšanje društva.
- Bitcoin vraća zdrav razum pozajmljivanju, uklanjanjem apsurdnih situacija poput negativnih kamatnih stopa (gde zajmitelj plaća da bi se zadužio).
- Bitcoin pokreće ulaganja u obnovljive izvore energije i poboljšava energetsku efikasnost u mreži, služeći kao „krajnji kupac“ za sve vrste energije.

@ 6ad3e2a3:c90b7740
2025-05-20 13:49:50I’ve written about MSTR twice already, https://www.chrisliss.com/p/mstr and https://www.chrisliss.com/p/mstr-part-2, but I want to focus on legendary short seller James Chanos’ current trade wherein he buys bitcoin (via ETF) and shorts MSTR, in essence to “be like Mike” Saylor who sells MSTR shares at the market and uses them to add bitcoin to the company’s balance sheet. After all, if it’s good enough for Saylor, why shouldn’t everyone be doing it — shorting a company whose stock price is more than 2x its bitcoin holdings and using the proceeds to buy the bitcoin itself?
Saylor himself has said selling shares at 2x NAV (net asset value) to buy bitcoin is like selling dollars for two dollars each, and Chanos has apparently decided to get in while the getting (market cap more than 2x net asset value) is good. If the price of bitcoin moons, sending MSTR’s shares up, you are more than hedged in that event, too. At least that’s the theory.
The problem with this bet against MSTR’s mNAV, i.e., you are betting MSTR’s market cap will converge 1:1 toward its NAV in the short and medium term is this trade does not exist in a vacuum. Saylor has described how his ATM’s (at the market) sales of shares are accretive in BTC per share because of this very premium they carry. Yes, we’ll dilute your shares of the company, but because we’re getting you 2x the bitcoin per share, you are getting an ever smaller slice of an ever bigger overall pie, and the pie is growing 2x faster than your slice is reducing. (I https://www.chrisliss.com/p/mstr how this works in my first post.)
But for this accretion to continue, there must be a constant supply of “greater fools” to pony up for the infinitely printable shares which contain only half their value in underlying bitcoin. Yes, those shares will continue to accrete more BTC per share, but only if there are more fools willing to make this trade in the future. So will there be a constant supply of such “fools” to keep fueling MSTR’s mNAV multiple indefinitely?
Yes, there will be in my opinion because you have to look at the trade from the prospective fools’ perspective. Those “fools” are not trading bitcoin for MSTR, they are trading their dollars, selling other equities to raise them maybe, but in the end it’s a dollars for shares trade. They are not selling bitcoin for them.
You might object that those same dollars could buy bitcoin instead, so they are surely trading the opportunity cost of buying bitcoin for them, but if only 5-10 percent of the market (or less) is buying bitcoin itself, the bucket in which which those “fools” reside is the entire non-bitcoin-buying equity market. (And this is not considering the even larger debt market which Saylor has yet to tap in earnest.)
So for those 90-95 percent who do not and are not presently planning to own bitcoin itself, is buying MSTR a fool’s errand, so to speak? Not remotely. If MSTR shares are infinitely printable ATM, they are still less so than the dollar and other fiat currencies. And MSTR shares are backed 2:1 by bitcoin itself, while the fiat currencies are backed by absolutely nothing. So if you hold dollars or euros, trading them for MSTR shares is an errand more sage than foolish.
That’s why this trade (buying BTC and shorting MSTR) is so dangerous. Not only are there many people who won’t buy BTC buying MSTR, there are many funds and other investment entities who are only able to buy MSTR.
Do you want to get BTC at 1:1 with the 5-10 percent or MSTR backed 2:1 with the 90-95 percent. This is a bit like medical tests that have a 95 percent accuracy rate for an asymptomatic disease that only one percent of the population has. If someone tests positive, it’s more likely to be a false one than an indication he has the disease*. The accuracy rate, even at 19:1, is subservient to the size of the respective populations.
At some point this will no longer be the case, but so long as the understanding of bitcoin is not widespread, so long as the dollar is still the unit of account, the “greater fools” buying MSTR are still miles ahead of the greatest fools buying neither, and the stock price and mNAV should only increase.
. . .
One other thought: it’s more work to play defense than offense because the person on offense knows where he’s going, and the defender can only react to him once he moves. Similarly, Saylor by virtue of being the issuer of the shares knows when more will come online while Chanos and other short sellers are borrowing them to sell in reaction to Saylor’s strategy. At any given moment, Saylor can pause anytime, choosing to issue convertible debt or preferred shares with which to buy more bitcoin, and the shorts will not be given advance notice.
If the price runs, and there is no ATM that week because Saylor has stopped on a dime, so to speak, the shorts will be left having to scramble to change directions and buy the shares back to cover. Their momentum might be in the wrong direction, though, and like Allen Iverson breaking ankles with a crossover, Saylor might trigger a massive short squeeze, rocketing the share price ever higher. That’s why he actually welcomes Chanos et al trying this copycat strategy — it becomes the fuel for outsized gains.
For that reason, news that Chanos is shorting MSTR has not shaken my conviction, though there are other more pertinent https://www.chrisliss.com/p/mstr-part-2 with MSTR, of which one should be aware. And as always, do your own due diligence before investing in anything.
* To understand this, consider a population of 100,000, with one percent having a disease. That means 1,000 have it, 99,000 do not. If the test is 95 percent accurate, and everyone is tested, 950 of the 1,000 will test positive (true positives), 50 who have it will test negative (false negatives.) Of the positives, 95 percent of 99,000 (94,050) will test negative (true negatives) and five percent (4,950) will test positive (false positives). That means 4,950 out of 5,900 positives (84%) will be false.

2025-05-20 06:15:51Deliberate (?) trade-offs we make for the sake of output speed.
... By sacrificing depth in my learning, I can produce substantially more work. I’m unsure if I’m at the correct balance between output quantity and depth of learning. This uncertainty is mainly fueled by a sense of urgency due to rapidly improving AI models. I don’t have time to learn everything deeply. I love learning, but given current trends, I want to maximize immediate output. I’m sacrificing some learning in classes for more time doing outside work. From a teacher’s perspective, this is obviously bad, but from my subjective standpoint, it’s unclear.
Finding the balance between learning and productivity. By trade, one cannot be productive in specific areas without first acquire the knowledge to define the processes needed to deliver. Designing the process often come on a try and fail dynamic that force us to learn from previous mistakes.
I found this little journal story fun but also little sad. Vincent's realization, one of us trading his learnings to be more productive, asking what is productivity without quality assurance?
Inevitably, parts of my brain will degenerate and fade away, so I need to consciously decide what I want to preserve or my entire brain will be gone. What skills am I NOT okay with offloading? What do I want to do myself?

@ c066aac5:6a41a034
2025-04-05 16:58:58I’m drawn to extremities in art. The louder, the bolder, the more outrageous, the better. Bold art takes me out of the mundane into a whole new world where anything and everything is possible. Having grown up in the safety of the suburban midwest, I was a bit of a rebellious soul in search of the satiation that only came from the consumption of the outrageous. My inclination to find bold art draws me to NOSTR, because I believe NOSTR can be the place where the next generation of artistic pioneers go to express themselves. I also believe that as much as we are able, were should invite them to come create here.
My Background: A Small Side Story
My father was a professional gamer in the 80s, back when there was no money or glory in the avocation. He did get a bit of spotlight though after the fact: in the mid 2000’s there were a few parties making documentaries about that era of gaming as well as current arcade events (namely 2007’sChasing GhostsandThe King of Kong: A Fistful of Quarters). As a result of these documentaries, there was a revival in the arcade gaming scene. My family attended events related to the documentaries or arcade gaming and I became exposed to a lot of things I wouldn’t have been able to find. The producer ofThe King of Kong: A Fistful of Quarters had previously made a documentary calledNew York Dollwhich was centered around the life of bassist Arthur Kane. My 12 year old mind was blown: The New York Dolls were a glam-punk sensation dressed in drag. The music was from another planet. Johnny Thunders’ guitar playing was like Chuck Berry with more distortion and less filter. Later on I got to meet the Galaga record holder at the time, Phil Day, in Ottumwa Iowa. Phil is an Australian man of high intellect and good taste. He exposed me to great creators such as Nick Cave & The Bad Seeds, Shakespeare, Lou Reed, artists who created things that I had previously found inconceivable.
I believe this time period informed my current tastes and interests, but regrettably I think it also put coals on the fire of rebellion within. I stopped taking my parents and siblings seriously, the Christian faith of my family (which I now hold dearly to) seemed like a mundane sham, and I felt I couldn’t fit in with most people because of my avant-garde tastes. So I write this with the caveat that there should be a way to encourage these tastes in children without letting them walk down the wrong path. There is nothing inherently wrong with bold art, but I’d advise parents to carefully find ways to cultivate their children’s tastes without completely shutting them down and pushing them away as a result. My parents were very loving and patient during this time; I thank God for that.
With that out of the way, lets dive in to some bold artists:
Nicolas Cage: Actor
There is an excellent video by Wisecrack on Nicolas Cage that explains him better than I will, which I will linkhere. Nicolas Cage rejects the idea that good acting is tied to mere realism; all of his larger than life acting decisions are deliberate choices. When that clicked for me, I immediately realized the man is a genius. He borrows from Kabuki and German Expressionism, art forms that rely on exaggeration to get the message across. He has even created his own acting style, which he calls Nouveau Shamanic. He augments his imagination to go from acting to being. Rather than using the old hat of method acting, he transports himself to a new world mentally. The projects he chooses to partake in are based on his own interests or what he considers would be a challenge (making a bad script good for example). Thus it doesn’t matter how the end result comes out; he has already achieved his goal as an artist. Because of this and because certain directors don’t know how to use his talents, he has a noticeable amount of duds in his filmography. Dig around the duds, you’ll find some pure gold. I’d personally recommend the filmsPig, Joe, Renfield, and his Christmas film The Family Man.
Nick Cave: Songwriter
What a wild career this man has had! From the apocalyptic mayhem of his band The Birthday Party to the pensive atmosphere of his albumGhosteen, it seems like Nick Cave has tried everything. I think his secret sauce is that he’s always working. He maintains an excellent newsletter calledThe Red Hand Files, he has written screenplays such asLawless, he has written books, he has made great film scores such asThe Assassination of Jesse James by the Coward Robert Ford, the man is religiously prolific. I believe that one of the reasons he is prolific is that he’s not afraid to experiment. If he has an idea, he follows it through to completion. From the albumMurder Ballads(which is comprised of what the title suggests) to his rejected sequel toGladiator(Gladiator: Christ Killer), he doesn’t seem to be afraid to take anything on. This has led to some over the top works as well as some deeply personal works. Albums likeSkeleton TreeandGhosteenwere journeys through the grief of his son’s death. The Boatman’s Callis arguably a better break-up album than anything Taylor Swift has put out. He’s not afraid to be outrageous, he’s not afraid to offend, but most importantly he’s not afraid to be himself. Works I’d recommend include The Birthday Party’sLive 1981-82, Nick Cave & The Bad Seeds’The Boatman’s Call, and the filmLawless.
Jim Jarmusch: Director
I consider Jim’s films to be bold almost in an ironic sense: his works are bold in that they are, for the most part, anti-sensational. He has a rule that if his screenplays are criticized for a lack of action, he makes them even less eventful. Even with sensational settings his films feel very close to reality, and they demonstrate the beauty of everyday life. That's what is bold about his art to me: making the sensational grounded in reality while making everyday reality all the more special. Ghost Dog: The Way of the Samurai is about a modern-day African-American hitman who strictly follows the rules of the ancient Samurai, yet one can resonate with the humanity of a seemingly absurd character. Only Lovers Left Aliveis a vampire love story, but in the middle of a vampire romance one can see their their own relationships in a new deeply human light. Jim’s work reminds me that art reflects life, and that there is sacred beauty in seemingly mundane everyday life. I personally recommend his filmsPaterson,Down by Law, andCoffee and Cigarettes.
NOSTR: We Need Bold Art
NOSTR is in my opinion a path to a better future. In a world creeping slowly towards everything apps, I hope that the protocol where the individual owns their data wins over everything else. I love freedom and sovereignty. If NOSTR is going to win the race of everything apps, we need more than Bitcoin content. We need more than shirtless bros paying for bananas in foreign countries and exercising with girls who have seductive accents. Common people cannot see themselves in such a world. NOSTR needs to catch the attention of everyday people. I don’t believe that this can be accomplished merely by introducing more broadly relevant content; people are searching for content that speaks to them. I believe that NOSTR can and should attract artists of all kinds because NOSTR is one of the few places on the internet where artists can express themselves fearlessly. Getting zaps from NOSTR’s value-for-value ecosystem has far less friction than crowdfunding a creative project or pitching investors that will irreversibly modify an artist’s vision. Having a place where one can post their works without fear of censorship should be extremely enticing. Having a place where one can connect with fellow humans directly as opposed to a sea of bots should seem like the obvious solution. If NOSTR can become a safe haven for artists to express themselves and spread their work, I believe that everyday people will follow. The banker whose stressful job weighs on them will suddenly find joy with an original meme made by a great visual comedian. The programmer for a healthcare company who is drowning in hopeless mundanity could suddenly find a new lust for life by hearing the song of a musician who isn’t afraid to crowdfund their their next project by putting their lighting address on the streets of the internet. The excel guru who loves independent film may find that NOSTR is the best way to support non corporate movies. My closing statement: continue to encourage the artists in your life as I’m sure you have been, but while you’re at it give them the purple pill. You may very well be a part of building a better future.

Google izveštava o stalnom povećanju interesa u svetu za pitanje „Šta je novac?“ koji se postavlja iz godine u godinu, od 2004. do 2021., a sa naglim porastom nakon finansijske krize 2008. godine.
I izgleda se da niko nema dobar odgovor za to.
Godišnji proseci mesečnih interesa za pretragu. 100 predstavlja najveći interes za pretragu tokom čitavog perioda, koji se dogodio u decembru 2019. Podaci sa Google Trends-a.
Međutim, odgovaranje na ovo naizgled jednostavno pitanje pomoći će vam da razjasnite ulogu novca u vašem životu. Jednom kada shvatite kako novac funkcioniše, tačno ćete videti i zašto svet danas ludi – i šta učiniti povodom toga. Zato hajde da se udubimo u to.
Na pitanje šta je novac, većina ljudi otvori svoje novčanike i pokaže nekoliko novčanica – “evo, ovo je novac!”
Ali po čemu se ove novčanice razlikuju od stranica vaše omiljene knjige? Pa, naravno, zavod za izradu novčanica te zemlje je odštampao te novčanice iz vašeg novčanika kako bi se oduprla falsifikovanju, i svi ih koriste da bi kupili odredjene stvari.
Međutim, Nemačka Marka imala je sva ova svojstva u prošlosti – ali preduzeća danas ne prihvataju te novčanice. Zapravo, građani Nemačke su početkom dvadesetih godina prošlog veka spaljivali papirne Marke kako bi grejali svoje domove. Marka je imala veću vrednost kao papir za potpalu nego kao novac!
1923. nemačka valuta poznata kao Marka bila je jeftinija od uglja i drveta!
Pa šta to čini novac, novcem?
Ispostavilo se da ovo nije pitanje na koje je lako dati odgovor.
Definisanje novca
Novac nije fizička stvar poput novčanice dolara. Novac je društveni sistem koji koristimo da bismo olakšali trgovinu robom i uslugama. Međutim, tokom istorije fizička monetarna dobra igrala su ključnu ulogu u društvenom sistemu novca, često kao znakovi koji predstavljaju vrednost u monetarnom sistemu. Ovaj sistem ima tri funkcije: 1) Sredstvo Razmene, 2) Obračunsku Jedinicu i 3) Zalihu Vrednosti.
Odakle dolaze ove funkcije, i zašto su one vredne?
Šta je sredstvo razmene?
Sredstvo razmene je neko dobro koje se obično razmenjuje za drugo dobro. Najčešće objašnjenje za to kako su se pojavila sredstva razmene glasi otprilike ovako: Boris ima ječam i želeo bi da kupi ovcu od Marka. Marko ima ovce, ali želi samo piliće. Ana ima piliće, ali ona ne želi ječam ili ovce.
To se naziva problem sticaja potreba: dve strane moraju da žele ono što druga ima da bi mogle da trguju. Ako se želje dve osobe ne podudaraju, oni moraju da pronađu druge ljude sa kojima će trgovati dok svi ne pronađu dobro koje žele.
Ljudi koji trguju robom i uslugama moraju da imaju potrebe koje se podudaraju.
Vremenom, veoma je verovatno da će se određena vrsta robe, poput pšenice, pojaviti kao sredstvo razmene jer su je mnogi ljudi želeli. Uzimajući pšenicu kao primer: pšenica je rešila “sticaje potreba” u mnogim zanatima, jer čak i ako onaj koji prima pšenicu a nije želeo da je koristi za sebe, znao je da će je neko drugi želeti.
Ovo nazivamo prodajnost imovine.
Pšenica je dobar primer dobra za prodaju jer svi moraju da jedu, a od pšenice se pravi hleb. Pšenica ima vrednost kao sastojak hleba i kao dobro koje olakšava trgovinu rešavanjem problema „sticaja potreba“.
Razmislite o svojoj želji da dobijete više novčanica u eurima ili drugoj valuti. Ne možete da jedete novčanice da biste preživeli, a i ne bi vam bile od velike koristi ako poželite da ih koristite kao građevinski materijal za vašu kuću. Međutim, znate da sa tim novčanicama možete da kupite hranu i kuću.
Stvarne fizičke novčanice su beskorisne za vas. Novčanice su vam dragocene samo zato što će ih drugi prihvatiti za stvari koje su vama korisne.
Tokom dugog perioda istorije, novac je evoluirao do te mere da monetarno dobro može imati vrednost, a da to dobro ne služi za bilo koju drugu ‘suštinsku’ upotrebu, poput hrane ili energije. Umesto toga, njegova upotreba je zaliha vrednosti i jednostavna zamena za drugu robu u bilo kom trenutku koji poželite.
Šta jedno dobro čini poželjnijim i prodajnijim od drugog dobra?
Deljivost
Definicija: Sposobnost podele dobra na manje količine.
Loš Primer: Dijamante je teško podeliti na manje komade. Za zajednicu od hiljada ljudi koji dnevno izvrše milione transakcija, dijamanti čine loše sredstvo razmene. Previše su retki i nedeljivi da bi se koristili za mnoge transakcije.
Ujednačenost
Definicija: Sličnost pojedinačnih jedinica odredjenog dobra.
Loš Primer: Krave nisu ujednačene – neke su veće, neke manje, neke bolesne, neke zdrave. Sa druge strane, unca čistog zlata je jednolična – jedna unca je potpuno ista kao sledeća. Ovo svojstvo se takođe često naziva zamenljivost.
Prenosivost
Definicija: Lakoća transporta dobra.
Loš Primer: Krava nije baš prenosiva. Zlatnici su prilično prenosivi. Papirne novčanice su još prenošljivije. Knjiga u kojoj se jednostavno beleži vlasništvo nad tim vrednostima (poput Rai kamenog sistema ili digitalnog bankovnog računa) je neverovatno prenosiva, jer nema fizičkog dobra koje treba nositi sa sobom za kupovinu. Postoji samo sistem za evidentiranje vlasništva nad tim vrednostima u nematerijalnom obliku.
Kako dobro postaje sredstvo razmene?
Dobra postaju, i ostaju sredstva razmene zbog svoje univerzalne potražnje, takođe poznate kao njihova prodajnost, čemu pomažu svojstva koja su gore nabrojana.
Mnogo različitih dobara mogu u različitoj meri delovati kao sredstva razmene u ekonomiji. Danas, naša globalna ekonomija koristi valute koje izdaju države, zlato, pa čak i robu poput nafte kao sredstvo razmene.
Šta je obračunska jedinica?
Stvari se komplikuju kada u ekonomiji postoji mnogo robe koja se prodaje. Čak i sa samo 5 dobara, postoji 10 “kurseva razmene” između svake robe kojih svi u ekonomiji moraju da se sete: 1 svinja se menja za 15 pilića, 1 pile se menja za 15 litara mleka, desetak jaja se menja za 15 litara mleka, i tako dalje. Ako ekonomija ima 50 dobara, među njima postoji 1.225 “kurseva razmene”!
Sredstvo za merenje vrednosti
Zamislite obračunsku jedinicu kao sredstvo za merenje vrednosti. Umesto da se sećamo vrednosti svakog dobra u poredjenju sa drugim dobrima, mi samo treba da se setimo vrednosti svakog dobra u poredjenju sa jednim dobrom – obračunskom jedinicom.
Umesto da se setimo 1.225 kurseva razmene kada imamo 50 proizvoda na tržištu, mi treba da zapamtimo samo 50 cena.
Na primer, ne treba da se sećamo da litar mleka vredi 1/15 piletine ili desetak jaja, možemo da se samo setimo da litar mleka košta 1USD.
Poređenje dobara je lakše sa obračunskom jedinicom
Obračunska jedinica takođe olakšava upoređivanje vrednosti i donošenje odluka. Zamislite da pokušavate da kupite par Nike Air Jordan patika kada ih jedan prodavac prodaje za jedno pile, a drugi za 50 klipova kukuruza.
Šta je zaliha vrednosti?
Do sada smo gledali samo primere transakcija koje se odvijaju u određenom trenutku u vremenu.
Međutim, ljudi vrše transakcije tokom vremena – oni štede novac i troše ga kasnije. Da bi odredjeno dobro moglo da funkcioniše pravilno kao monetarno dobro, ono treba da održi vrednost tokom vremena.
Novac koji vremenom dobro drži vrednost daje njegovom imaocu više izbora kada će taj novac da potroši.
To znači da prodajnost dobra uključuje njegovu sposobnost da održi vrednost tokom vremena.
Šta jedno dobro čini boljom zalihom vrednosti od drugog dobra?
Trajnost
Definicija: Sposobnost dobra da vremenom zadrži svoj oblik.
Loš Primer: Jagode čine lošu zalihu vrednosti jer se lako oštete i brzo trunu.
Odluka je daleko lakša ako jedan prodavac naplaćuje 150 USD, a drugi 200 USD – odmah je očigledno koja je bolja ponuda jer su vrednosti izražene u istoj jedinici.
Teške za Proizvodnju
Definicija: Teškoće koje ljudi imaju u proizvodnji veće količine dobra.
Loš Primer: Papirne novčanice predstavljaju lošu zalihu vrednosti jer banke i vlade mogu jeftino da ih naprave.
Sa zlatom je suprotno – u ponudi se nalazi ograničena količina uprkos velikoj potražnji za njim, jednostavno zato što ga je vrlo teško iskopati iz zemlje. Ova ograničena ponuda osigurava da svaka jedinica zlata održi vrednost tokom vremena.
Kako dobra postaju zalihe vrednosti?
Dobro postaje zaliha vrednosti ako se vremenom pokaže trajnim i teškim za proizvodnju.
Samo će vreme pokazati da li je neko dobro zaista trajno i da li ga je teško proizvesti. Zbog toga neki oblici novca su postojali vekovima pre nego što je neko otkrio način da ih proizvede više, i na kraju se to dobro više nije koristilo kao novac.
Ovo je priča o školjkama, Rai kamenju i mnogim drugim oblicima novca tokom istorije.
Zlato je primer dobra koje je hiljadama godina služilo kao dobra zaliha vrednosti. Zlato se ne razgrađuje tokom vremena i još uvek ga je teško proizvesti. Hiljadama godina alhemičari su bezuspešno pokušavali da sintetišu zlato iz jeftinih materijala.
Čak i sa današnjim naprednim rudarskim tehnikama, svake godine svi svetski rudnici zlata zajedno mogu da proizvedu samo 2% od ukupne ponude zlata u prometu.
Teškoće u proizvodnji zlata daju izuzetno visok odnos “zaliha i protoka”: zaliha je broj postojećih jedinica, a protok su nove jedinice stvorene tokom određenog vremenskog perioda. Svake godine se stvori vrlo malo novih jedinica zlata, iako je potražnja za zlatom obično vrlo velika.
Kombinujući ovo sa deljivošću, ujednačenošću i prenosivošću zlata, nije ni čudo što je zlato čovečanstvu služilo kao monetarno dobro tokom poslednjih 5.000 godina. Pošto je zlato teško proizvesti, možemo ga nazvati teškim novcem (hard money).
Kao rezultat toga, svoju vrednost je u velikoj meri zadržao kroz milenijume. Cena većine dobara i usluga u pogledu zlata zapravo se vremenom smanjivala kao rezultat tehnoloških inovacija, koje sve proizvode čine jeftinijim.
Uzmimo na primer cene hrane prema praćenju Kancelarije za hranu i poljoprivredu UN-a: sa obzirom na skokove u poljoprivrednoj tehnologiji tokom poslednjih 60 godina, cene hrane drastično su pale kada se procenjuju u zlatu. To čak i važi uprkos činjenici da obični ljudi retko koriste zlato za kupovinu stvari.
Cene hrane su padale u pogledu zlata tokom proteklih 60 godina, i mnogo pre toga (FAO Indeks Cena Hrane u Zlatu)
Zaliha vrednosti omogućava ljudima da uštede novac kako bi mogli da ga ulažu u pokretanje preduzeća i obrazovanje, povećavajući produktivnost društva.
Monetarna dobra koja dobro čuvaju vrednost takođe podstiču dugoročniji pogled na život, ili kratke vremenske preference. Pojedinac može da radi 10 godina, uštedi odredjeno monetarno dobro koje je dobra zaliha vrednosti, i nema potrebe da se plaši da će njegova ušteđevina biti izbrisana krahom tržišta ili povećanjem ponude tog dobra.
Zašto su važne funkcije novca?
Kada neki oblik novca izgubi bilo koju od svojih važnih funkcija kao što su sredstvo razmene, obračunska jedinica i zaliha vrednosti, celokupna ekonomija i društvo mogu da se rastrgnu.
Tokom istorije često vidimo grupe ljudi koje eksploatišu druge iskorišćavajući nesporazume o novcu i važnosti njegovih funkcija.
Sledeće, proći ću kroz istoriju novca, prvo hipotetički da bih ilustrovao poentu, a zatim ću preći na stvarne istorijske primere. Kroz ove primere videćemo štetne efekte na društva u slučajevima kada se izgubi samo jedna od tih ključnih funkcija novca.
Novac Gubi Funkciju: Alhemičar iz Njutonije
Kroz istoriju, mnoga dobra su dolazila i odlazila kao oblici novca. Na žalost, kada se neki oblik novca ukine, ponekad postoji grupa ljudi koja eksploatiše drugi oblik manipulišući tim novcem.
Hajde da pogledamo hipotetičko selo zvano Njutonija da bismo razumeli kako dolazi do ove eksploatacije.
Zelene perle postaju Novac
Tokom stotina godina ribolova u obližnjoj reci, stanovnici Njutonije sakupljali su zelene perle iz vode. Zrnca su mala, lagana, izdržljiva, jednolična i retko se pojavljuju u reci. Ljudi prvo priželjkuju perle zbog svoje lepote. Na kraju, seljani shvataju da svi drugi žele perle – one se vrlo lako mogu prodati. Zrnca uskoro postaju sredstvo razmene i obračunska jedinica u selu: pile je 5 zrna, vreća jabuka 2 zrna, krava 80 zrna.
Ukupna ponuda perli je prilično konstantna i cene se vremenom ne menjaju mnogo. Seoski starešina je uveren da može da se opustiti u poslednjim danima živeći od svoje velike zalihe perli.
Alhemičar stvara više perli
Seoski alhemičar je poželeo da bude bogat čovek, ali nije voleo da vredno radi na tome. Umesto da traži perle u reci ili da prodaje vrednu robu drugim seljanima, on sedeo je u svojoj laboratoriji. Na kraju je otkrio kako da lako stvori stotine perli sa malo peska i vatre.
Seljani koji su tragali za perlama u reci bili su srećni ako bi svaki dan pronašli po 1 zrno. Alhemičar je mogao da proizvede stotine uz malo napora.
Alhemičar troši svoje perle
Budući da je bio prilično zao, alhemičar nije svoj metod pravljenja zrna delio ni sa kim drugim. Stvorio je sebi još više perli i počeo da ih troši za dobra na tržištu u Njutoniji. Tokom sledećih meseci, alhemičar je kupio farmu pilića, nekoliko krava, finu svilu, posteljine i ogromno imanje. On je imao priliku da kupi ova dobra po normalnim cenama na tržištu.
Alhemičarevo trošenje ostavljalo je seljanima mnogo perli, ali malo njihove vredne robe.
Svi seljani su se osećali bogatima – imali su tone perli! Međutim, polako su primetili da i svi ostali takodje imaju tone.
Cene počinju da rastu
Uzgajivač pilića primetio je da sva roba koju je trebalo da kupi na pijaci poskupela. Džak jabuka sada se prodaje za 100 perli – 50 puta više od njihove cene pre nekoliko meseci!
Iako je sada imao hiljade perli, uskoro bi mogao da ostane bez njih zbog ovih cena. Pitao se – da li zaista može sebi da priušti da prodaje svoje piliće za samo 5 perli po komadu? Morao je i on da podigne svoje cene.
Jednostavno rečeno, kao rezultat alhemičarevog trošenja njegovih novostvorenih perli, bilo je previše perli koje su jurile premalo dobara – pa su cene porasle.
Kupci robe bili su spremni da potroše više perli da bi kupili potrebna dobra. Prodavci robe su trebali da naplate više da bi bili sigurni da su zaradili dovoljno da kupe potrebna dobra za sebe.
Budući da su cene svih dobara porasle, možemo reći da se vrednost svake perle smanjila.
Nejednakost bogatstva raste
Seoski starešina, koji je vredno radio da sačuva hiljade perli, sada se našao osiromašenim i gladnim. U međuvremenu, alhemičar je udobno sedeo na svom velikom imanju sa kravama, pilićima i slugama koji su se brinuli za svaki njegov hir.
Alhemičar je efikasno ukrao bogatstvo celog sela, tako što je jeftino proizvodio perle i koristio ih za kupovinu vredne robe.
Ono što je najvažnije, kupio je robu pre nego što je tržište shvatilo da je više perli u opticaju i da ima manje robe, što je dovelo do rasta cena. Ova dodatna proizvodnja perli nije dodala korisnu robu ili usluge selu.
Eksploatacija pomoću Novca: Agri Perle
Nažalost, priča o alhemičaru iz Njutonije nije u potpunosti hipotetička. Ovaj prenos bogatstva kroz stvaranje novca ima istorijske i moderne presedane.
Na primer, afrička plemena su nekada koristila staklene perle, poznate kao “agri perle”, kao sredstvo razmene. U to vreme plemenskim ljudima je bilo veoma teško da prave staklene perle, i one su predstavljale težak novac unutar njihovog plemenskog društva.
Niko nije mogao jeftino da proizvede perle i koristiti ih za kupovinu skupe, vredne robe poput kuća, hrane i odeće.
Sve se promenilo kada su stigli Evropljani, i primetili upotrebu staklenih perli kao novca.
U to vreme, Evropljani su mogli jeftino da stvaraju staklo u velikim količinama. Kao rezultat toga, Evropljani su počeli tajno da uvoze perle i koriste ih za kupovinu dobara, usluga i robova od Afrikanaca.
Vremenom se iz Afrike izvlačila vredna roba i ljudi, dok je plemenima ostajalo mnogo perli i malo robe.
Perle su izgubile veći deo vrednosti zbog inflacije uzrokovane snabdevanjem od strane Evropljana.
Rezultat je bio osiromašenje afričkih plemena i bogaćenje Evropljana, kako to ovde objašnjava monetarni istoričar Bezant Denier.
Dragocena roba je kupljena jeftino proizvedenim monetarnim dobrom.
Profitiranje na proizvodnji novca: Emisiona dobit
Ova priča ilustruje kako se bogatstvo prenosi kada jedna grupa može jeftino da proizvodi monetarno dobro.
Razlika između troškova proizvodnje monetarnog dobra i vrednosti tog monetarnog dobra poznata je kao emisiona dobit, eng. seignorage.
Kada je monetarno dobro mnogo vrednije od troškova proizvodnje, ljudi će proizvesti više od monetarnog dobra da bi uhvatili profit od emisione dobiti.
Na kraju će ova povećana ponuda dovesti do pada vrednosti monetarnog dobra. To je zbog zakona ponude i potražnje: kada se ponuda povećava, cena (poznata i kao vrednost) dobra opada.
Novac Gubi Funkciju 2. Deo: Kejnslandski Bankar
U priči o Njutoniji, alhemičar je otkrio način da se od malo peska jeftino stvori više zelenih perli. To se u stvarnosti odigralo kroz trgovinu između Evropljana i Afrikanaca, pričom o agri perlama. Međutim, ove priče su pomalo zastarele – mi više ne trgujemo robom za perle.
Da bismo nas doveli do modernog doba, hajde da promenimo neka imena u našoj priči:
- Selo Njutonija postaje država koja se zove Kejnsland
- Alhemičar postaje bankar
- Seoski starešina postaje penzioner
- Zelene perle postaju zlato, koje niko ne može jeftinije da stvori – čak ni bankar.
Bankar Menja Papirne Novčanice za Zlato
Kao i u stvarnosti, bankar u ovoj priči nema formulu ili trik da stvori više zlata. Međutim, bankar bezbedno čuva zlato u vlasništvu svakog građanina Kejnslanda. Bankar daje svakom građaninu po jednu potvrdu za svaku uncu zlata koje ima u svom trezoru.
Te potvrde se mogu iskoristiti u bilo koje vreme za stvarno zlato. Papirne potvrde ili novčanice su mnogo pogodnije za plaćanje nego nošenje zlata kroz supermarket.
Građani su srećni – oni imaju prikladno sredstvo plaćanja u vidu bankarevih novčanica, i znaju da niko ne može da ukrade njihovo bogatstvo falsifikujući više zlata.
Građani na kraju počinju da plaćaju u potpunosti papirnim novčanicama, ne trudeći se nikad da zamene svoje novčanice za zlato. Na kraju, novčanice postaju “dobre kao i zlato” – svaka predstavlja fiksnu količinu zlata u bankarevom trezoru.
Ukupno kruži 1.000.000 novčanica, od kojih je svaka otkupljiva za jednu uncu zlata. 1.000.000 unci zlata sedi u bankarevom trezoru. Svaka novčanica je u potpunosti podržana u zlatu.
Starešina koji je sačuvao sve svoje perle u priči o Njutoniji sada je penzioner u Kejnslandu, koji svoje zlato drži u banci i planira da ugodno živi od novčanica koje je dobio zauzvrat.
Hajde da u ovu priču dodamo i novi lik: premijera Kejnslanda. Premijer naplaćuje porez od građana i koristi ga za plaćanje javnih usluga poput policije i vojske. Premijer takođe drži vladino zlato kod bankara.
Bankar Menja Papirne Novčanice za Dug
Premijer želi da osigura da nacionalno zlato ostane na sigurnom, pa banku štiti policijom. Bankar i premijer se zbog toga zbližavaju, pa premijer traži uslugu. Traži od bankara da kreira 200.000 novčanica za premijera, uz obećanje da će mu premijer vratiti za pet godina. Premijeru su novčanice potrebne za finansiranje rata. Građani Kejnslanda borili su se protiv većih poreza zbog finansiranja rata, pa je morao da se obrati bankaru.
Bankar se slaže da izradi novčanice, ali pod jednim uslovom: bankar uzima deo od 10.000 novčanica za sebe. Premijer prihvata posao kojim bankar ’kupuje državni dug’. Sada je u opticaju 1.200.000 novčanica, potpomognutih kombinacijom 1.000.000 unci zlata i ugovorom o dugu sa vladom za 200.000 novčanica.
Premijer troši svoje nove novčanice na bombe kupujući ih od dobavljača iz domaće vojne industrije, a bankar sebi kupuje veliki luksuzni stan.
Dobavljač iz vojne industrije koristi sve nove novčanice koje je dobio od premijera da kupi amonijum nitrat (đubrivo koje se koristi u bombama) za proizvodnju bombi. Sve njegove kupovine povećavaju cenu đubriva za uzgajivače pšenice u Kejnslandu, pa oni podižu cenu pšenice.
Kao uzrok toga, pekar koji kupuje pšenicu treba da podigne cenu svog hleba da bi ostao u poslu. Na taj način cene u Kejnslandu počinju da rastu, baš kao što su to činile u Njutoniji kada su nove perle ušle u opticaj.
Papirne Novčanice Više Ne Predstavljaju Zlato
Penzioner nailazi na finansijski časopis u kojem se pominje premijerov dogovor da se zaduži za finansiranje rata. Obzirom da je mudar, on zna da bombe loše vraćaju ulaganje i sumnja da će premijer ikada da vrati svoj dug.
Ako on ‘podmiri’ svoj dug, to bi ostavilo 1.200.000 novčanica u opticaju sa samo 1.000.000 unci zlata da bi ih podržalo, obezvređujući njegovu ušteđevinu. Već oseća stisak u džepu zbog porasta cena, i on odlučuje da se uputi u lokalnu banku i preda svoje novčanice i zameni ih za zlato, koje niko ne može da napravi u većoj količini.
Kada penzioner stigne u banku, on zatiče i mnoge druge okupljene oko banke. Svi oni se nadaju da će uzeti zlato koje predstavljaju njihove novčanice. Građani Kejnslanda sa pravom se plaše da njihove novčanice gube na vrednosti – oni to već osećaju zbog porasta cena.
Vrata su zaključana, sa obaveštenjem bankara na njima:
Po nalogu premijera, onom koji se plaši za stabilnost ove bankarske institucije, ova banka više neće podržavati konvertibilnost papirnih novčanica u zlato. Hvala vam!
Gomila se razilazi, ostavljena sa jednim izborom: da zadrže svoje novčanice, koje sada vrede manje od 1 unce zlata. Građani sa dovoljno finansijske stabilnosti odlučuju da ulože svoje novčanice u kupovinu akcija banke i kompanija vojne industrije, koje dobro posluju jer mogu da kupuju stvari pre nego što se povećaju tržišne cene.
Mnogi ljudi nisu u mogućnosti da investiraju – oni moraju da gledaju kako njihove zarade stagniraju i kako njihova ušteđevina polako ali sigurno gubi vrednost.
Penzioner, koji se nadao da će živeti od novčanica koje je zaradio tokom svojih 40 radnih godina, sada 40 sati nedeljno provodi iza kase u lokalnoj prodavnici, pitajući se gde je sve pošlo po zlu.
Dug Nikada Nije Otplaćen
Prošlo je nekoliko godina, a premijerov dug prema banci dolazi na naplatu. Budući da je potrošio svih 200.000 novčanica na bombe, koje nemaju baš dobar povraćaj ulaganja, on nema novčanice koje može da vrati banci. Plus, premijer želi da kupi još bombi za svoj rat.
Bankar uverava premijera da je sve u redu. Bankar će napraviti novi ugovor o dugu za 600.000 novčanica, koji bi trebao da stigne na naplatu u narednih 5 godina. Premijer može da iskoristi 200.000 od tih novih 600.000 novčanica da vrati svoj prvobitni dug prema banci, zadrži još 300.000 da kupi još bombi i da 100.000 bankaru da bi mu platio njegove usluge.
To nastavlja da se dešava – svaki put kada dug dospeva na naplatu, bankar stvara više novčanica za vraćanje starijih dugova i daje premijeru još više novca za trošenje. Ovaj ciklus se nastavlja.
Šta se dešava u Kejnslandu?
- Oni koji prvi dobiju nove novčanice, gledaju kako se njihovo bogatstvo povećava
- To uključuje bankara, premijera, vladu i sve one koji mogu da pristupe mogućnostima za investiranje u preduzeća koja prva dobiju nove novčanice (finansijske, vojne itd.).
- Cene roba rastu
- Cene se ne povećavaju ravnomerno – one se povećavaju gde god nove novčanice prvo uđu u ekonomiju i od tog trenutka imaju efekat talasa na tržišta. U našem primeru prvo raste cena amonijum nitrata, zatim cena pšenice, pa cena hleba. A tek na kraju zarade običnih ljudi.
- Štednja i životni standard opšte populacije se smanjuju
- Najviše pate oni koji žive od plate do plate i ne mogu da ulažu. Čak i oni koji su u mogućnosti da investiraju podložni su hirovima tržišta. Mnogi su prisiljeni da prodaju svoje investicije po niskim cenama tokom pada tržišta samo da bi platili svoje dnevne potrebe.
- Razlika u prihodima i bogatstvu između bogatih i siromašnih se povećava
- Bogatstvo opšte populacije se smanjuje, dok se bogatstvo onih koji su blizu mesta gde se troše nove novčanice povećava. Rezultat je disparitet koji se vremenom samo proširuje.
Da li nas novac danas eksploatiše?
Priča o Njutoniji i stvarna priča o agri perlama u Africi deluju pomalo zastarelo. Priča o Kejnslandu, međutim, deluje neobično poznato. U našem svetu cene robe uvek rastu, i vidimo rekordne nivoe nejednakosti u bogatstvu.
U poslednjem odeljku ovog našeg članka Šta je novac, proći ću kroz nastanak bankarstva i korake koji su bili potrebni da se dođe do današnjeg sistema, gde banke i vlade sarađuju u kontroli ekonomije i samog novca.
Šta su banke, i odakle su one došle?
Pojava bankarstva verovatno se dogodila da bi olakšala poljoprivrednu trgovinu i da bi povećala pogodnosti. Iako su se mnoga društva na kraju konvergirala ka upotrebi zlata i srebra kao novca, ovi metali su bili teški i opasni za nošenje kao tovar. Međutim, u mnogim slučajevima ih nije ni trebalo prevoziti. Uzmite ovaj primer:
Grad treba da plati poljoprivrednicima na selu za žito, a poljoprivrednici gradskoj vojsci za zaštitu od varvara. U ovom dogovoru zlato se kreće u oba smera: prema poljoprivrednicima u selu kako bi im se platilo žito, i nazad u grad da bi se platila vojska. Da bi olakšali ove transakcije, preduzetnici su stvorili koncept banke. Banka je zlato čuvala u sigurnom trezoru i izdavala novčanice od papira. Svaka priznanica je predstavljala potvrdu da njen imaoc poseduje određenu količinu zlata u banci. Imaoc novčanice je u svako doba mogao da uzme svoje zlato nazad vraćanjem te novčanice banci.
Korisnici banke mogli su lakše da trguju sa novčanicama od papira, i onaj koji poseduje novčanice mogao je da preuzme njihovo fizičko zlato u bilo kom trenutku. To je te novčanice učinilo “dobrim kao i zlato”.
Banke su izdržavale svoje poslovanje naplaćujući od kupaca naknadu za skladištenje zlata ili pozajmljivanjem dela zlata i zaračunavanjem kamata na njega. Trgovina na ovaj način je mogla da se odvija sa laganim novčanicama od papira umesto sa teškim vrećama zlatnika.
Ovakva praksa sa transakcijama, korišćenjem papirne valute potpomognute monetarnim dobrima, verovatno je započela u Kini u 7. veku.
Na kraju se proširila Evropom 1600-ih, a svoj zalet dobila je u Holandiji sa bankama poput Amsterdamske Wisselbanke. Novčanice Wisselbank-e često su vredele više od zlata koje ih je podržavalo, zbog dodane vrednosti njihovih pogodnosti.
Uspon nacionalnih ‘centralnih banaka’
Tokom vekova, zlato je počelo da se sakuplja u trezorima banaka, jer su ljudi više voleli pogodnosti transakcija sa novčanicama.
Na kraju, nacionalne banke u vlasništvu vlada preuzele su ulogu čuvanja zlata od privatnih banaka koje su započeli preduzetnici.
Nacionalne papirne valute potpomognute zlatnim rezervama u nacionalnim bankama zamenile su novčanice iz privatnih banaka. Sve nacionalne valute bile su jednostavno potvrde za zlato koje se nalazilo u trezoru nacionalne banke.
Ovaj sistem je poznat kao zlatni standard – sve valute su jednostavno predstavljale različite težine zlata.
U gornjem levom uglu novčanice možete videti da piše da je novčanica “zamenljiva za zlato”. Savremeni dolari nemaju ovaj natpis, ali inače izgledaju vrlo slično. Izvor
Zlatni sistem je postojao veći deo vremena, sve do Prvog svetskog rata. Vladama je bilo teško da prikupe novac za ovaj rat putem poreza, pa su morale da budu kreativne.
Kada vlade troše više nego što zarađuju na porezima, to se naziva deficitna potrošnja.
Kako vlade mogu ovo da urade? Vlade to rade tako što pozajmljuju novac prodavajući svoj dug.
Tokom Prvog svetskog rata, vlade su građanima i preduzećima prodavale vrstu duga koja se naziva ratna obveznica. Kada građanin kupi ratnu obveznicu, on preda svoj novac vladi i dobije papir u kojem je stajalo vladino obećanje da će vlasniku obveznice vratiti novac, plus kamate, za nekoliko godina.
Plakat koji obaveštava građane, tražeći od njih da kupe ratne obveznice – što predstavlja zajam vladi. Izvor
Centralne banke ‘monetizuju’ državni dug
Međutim, građani i preduzeća nisu bili voljni da kupe dovoljno ratnih obveznica za finansiranje Prvog svetskog rata.
Vlade se nisu predale – pa su zatražile od svojih nacionalnih ‘centralnih banaka’ da one kupe ove obveznice. Centralne banke su otkupile obveznice, ali ih nisu platile valutom potpomognutom postojećim zlatnim rezervama, kao što su to činili građani i banke prilikom kupovine obveznica.
Centralne banke su umesto toga davale vladi novu, sveže štampanu papirnu valutu potpomognutu samo obveznicom. Ovu valutu podržalo je samo obećanje da će im vlada vratiti dugove. Ovo je poznato kao monetizacija duga.
Budući da su ratne obveznice i valuta samo komadi papira, one su lake i jeftine za proizvodnju i mogu se napraviti u ogromnim količinama. Ono što ograničava proizvodnju i jednog i drugog je poverenje.
Ima smisla da se neko rastane od svog teško stečenog novca da kupi državnu obveznicu, samo ako veruje da će vlada da vrati svoj dug, plus kamate. Centralna banka je “krajnji kupac”, što znači da će ona da kupi državne obveznice kada to niko drugi neće da uradi.
Zapamtite, centralnu banku gotovo da ništa ne košta da kupi državne obveznice, jer oni sami štampaju valutu da bi ih kupili.
Zamislite da pridjete najskupljem automobilu u autosalonu – koji košta 100.000 USD. Mislite da je automobil lep, ali taj novac biste radije potrošili na lepši stan – tako da ste spremni da platite samo 40.000 USD za taj auto.
Sada, hajde da zamislimo da imate štampač za novac i da vas košta samo 50 USD za mastilo i papir da bi ištampali 1.000.000 USD. Vi biste odmah kupili auto, čak i ako biste morali da se cenkate sa drugim čovekom, i da ga na kraju platite 150.000 USD!
Ista stvar se dešava kada centralna banka kupuje obveznice (dugove) od vlade. Centralna banka može da stvori valutu toliko jeftino, da su spremni da plate i više nego što bi drugi platili ove obveznice i nastaviće da ih kupuju čak i kada niko drugi ne bude želeo.
Monetizacija duga uzrokuje inflaciju
Kada centralne banke monetizuju državni dug, funkcija novca kao zalihe vrednosti počinje da se nagriza. Vlada troši novi novac koji je dobila od svoje centralne banke na ratnu robu, obroke i još mnogo toga.
Cene roba rastu od ove novoštampane valute koja kruži kroz ekonomiju. Kada se cene povećavaju, to znači da se vrednost svake jedinice valute smanjuje. Svi koji drže valutu sada imaju manje vrednosti. Danas to nazivamo sporim gubitkom funkcije zalihe vrednosti u novčanoj inflaciji.
Za Nemačku nakon Prvog svetskog rata monetizacija duga izazvala je totalni slom Nemačke ekonomije i stvorila uslove za rast fašizma.
Kao deo sporazuma o prekidu vatre koji je okončao Prvi svetski rat, Nemačka je pobednicima morala da plati ogroman novac. Nemačkoj vladi je bio preko potreban novac, pa su prodale obveznice (dug) Rajhsbanci, nemačkoj centralnoj banci.
Ovaj postupak doveo je do toga da je vlada štampala toliko maraka (tadašnja nemačka valuta) da je tempo inflacije u Nemačkoj ubrzan u hiperinflaciju početkom 1920-ih. Cena vekne hleba za samo 4 godine popela se sa 1,2 marke na 428 biliona maraka.
Tokom i posle Prvog svetskog rata, SAD, Britanija, Francuska i mnoge druge vlade pratile su Nemačku u štampanju valute potpomognute državnim dugom.
To je dovelo do toga da su građani želeli da svoju papirnu valutu zamene za zlato, baš kao i penzioner iz priče o Kejnslandu.
Međutim, mnoge vlade su suspendovale konvertibilnost svojih valuta u zlato. Ovim potezom vlade su primorale svoje građane da drže nacionalnu papirnu valutu i gledaju kako se njihova ušteda smanjuje u vrednosti.
Da bi mogle da nastave da štampaju novac i da bi ga trošile na nepopularne programe za koje nisu mogle da skupljaju poreze za finansiranje – poput ratova.
Bretton Woods: Novi monetarni sistem
Nakon razaranja koja su donela dva svetska rata, vlade su uspostavile novi globalni monetarni sistem prema Bretton Woods-ovom sporazumu iz 1944. godine.
Prema ovom sporazumu, valuta svake države konvertovala se po fiksnom kursu sa američkim dolarom. Američki dolar je zauzvrat predstavljao zlato po stopi od 35 USD za jednu trojsku uncu zlata*.
Sve globalne valute su stoga još uvek bile jednostavna reprezentacija zlata, putem američkih dolara kao posrednika. Redovni građani više nisu mogli da otkupljuju svoje valute za zlato iz Sjedinjenih Država. Međutim, strane centralne banke mogle bi da dođu u Sjedinjene Države da bi zamenile dolare za zlato po stopi od 35 USD za jednu uncu zlata.
Međutim, vlada Sjedinjenih Država nije uvek držala dovoljno zlata da podrži sve dolare u opticaju. Američka vlada nastavila je da finansira proširene socijalne i vojne programe prodajom državnog duga svojoj centralnoj banci, Federalnim rezervama, koja je povećala ponudu dolara bez povećanja ponude zlata koja podupire te dolare.
*Trojna unca je standardna mera čistog zlata i ima malo veću težinu od normalne unce.
Propast Bretton Woods-a
Tokom 1970-ih, sve veći troškovi rata u Vijetnamu i stranih vlada koje su otkupljivale svoje dolare za zlato, stvorili su pritisak na Trezor Sjedinjenih Država.
Ponuda dolara je porasla, dok je zlato u posedu Sjedinjenih Država opalo. Od 1950. pa do početka 1970-ih, rezerve zlata koje je držala vlada Sjedinjenih Država smanjile su se za više od 50%, sa 20 metričkih tona na samo 8 metričkih tona.
Godine 1970. država je imala zlata u vrednosti od samo 12 biliona dolara po zvaničnom kursu od 35 dolara za trojsku uncu zlata. Tokom ovog istog vremenskog perioda, ukupna ponuda američkih dolara otišla je sa oko 32 biliona USD na skoro 70 biliona USD.
Zvanične rezerve zlata u SAD-u su naglo padale od 1950. do 1970. godine, dok su se dolari u opticaju povećavali. Izvor: Wikipedia, DollarDaze.org
Američka vlada nije bila u stanju da potkrepi dolare zlatom od 35 dolara po trojnoj unci, što dovelo do rizika za čitav globalni monetarni sistem.
Početkom sedamdesetih godina, trojna unca zlata trebala je da vredi 200 USD da bi u potpunosti podržala sve američke dolare u opticaju. Rečeno na drugi način, Sjedinjene Države su pokušavale da kažu svetu da jedan dolar vredi 1/35 trojne unce zlata, ali u stvarnosti dolar je vredeo samo 1/200 trojne unce.
Kad su strane vlade trebale da pribave dolare za međunarodnu trgovinu i rezerve, bile su opelješene. Francuska vlada je to shvatila šezdesetih godina prošlog veka i počela je da prodaje svoje američke dolare za zlato po zvaničnom kursu od 35 dolara za trojsku uncu zlata.
Zemlje su počinjale da se bude iz šeme američke vlade. SAD su krale bogatstvo putem emisione dobiti, prodajući dolare za 1/35 trojne unce zlata, kada su vredeli samo 1/200 trojske unce.
Nixonov Šok ulazi u ’tradicionalni’ novac
Da bi kuća od karata mogla da ostane na mestu, predsednik Nixon je 1971. najavio da će američka vlada privremeno da obustavi konvertibilnost dolara u zlato.
Strane vlade više nisu mogle da polažu pravo na zlato svojim papirnim dolarima, a dolar više nije bio “poduprt” zlatom. Nixon je tvrdio da će ovo stabilizovati dolar.
50 godina kasnije, kristalno je jasno da je ovo samo pomoglo dolaru da izgubi vrednost i da ovaj “privremeni” program još uvek traje.
Pre 1971. godine, sve globalne valute bile su vezane za američki dolar putem Bretton Woods-ovog sporazuma. Kada je Nixon promenio američki dolar iz dolara podržanog u zlatu u dolar podržan dugom, ovim je promenio i svaku drugu valutu na Zemlji.
Sam je učinio da se celokupna svetska ekonomija zasniva na dugovima. Valute više nisu predstavljale zlato, već su predstavljale vrednost državnog duga.
Zlatni Standard se nikada nije vratio
Konvertibilnost američkih dolara u zlato – zlatni standard – nikada se nije vratio.
Od 1971. godine, čitav globalni monetarni sistem pokreće se tradicionalnim “fiat” valutama: poverenjem u vladine institucije da održavaju valutni sistem.
Većina valuta podržana je kombinacijom duga njihove vlade i drugih tradicionalnih valuta poput dolara i evra. Papirne valute više nisu podržane zlatom, imovinom koja je više od 5000 godina služila kao težak novac.
Danas vas vlade prisiljavaju da plaćate porez u njihovoj valuti i manipulišu saznanjima oko novca kako bi osigurale da potražnja za njihovom valutom ostane velika.
To im omogućava da neprestano štampaju više valuta, da bi je potrošili na vladine projekte, uzrokujući inflaciju cena koja jede i smanjuje bogatstvo i plate.
Američka vlada sada prodaje državne obveznice (dugove), poznate kao obveznice Trezora SAD, eng. US Treasuries, komercijalnim bankama u zamenu za američke dolare.
Vlada koristi te dolare za finansiranje svog budžetskog deficita. Komercijalne banke prodaju mnoge obveznice Trezora SAD, koje su kupile, američkoj centralnoj banci, Federalnim Rezervama.
Federalne rezerve plaćaju komercijalnim bankama sveže štampanim novcem “pomoću računara i upisivanjem količine na račun”, kako je rekao bivši predsednik Fed-a Ben Bernanke.
Ove komercijalne banke često zarađuju samo kupujući obveznice Trezora SAD od države i prodajući ih centralnoj banci. Kupujte nisko, prodajte visoko.
Centralne banke ovaj proces kupovine državnog duga – odnosno pozajmljivanja novca državi – nazivaju operacijama otvorenog tržišta.
Kada centralna banka odjednom kupi velike iznose duga, oni to nazivaju kvantitativnim ublažavanjem. Centralne banke javno najavljuju kupovinu državnog duga, ali vrlo malo ljudi razume šta to zapravo znači.
Euro, jen i svaka druga valuta koja se danas koristi funkcionišu slično kao američki dolar.
Da li će SAD ikada vratiti svoj nacionalni dug? Neobična stvar u vezi sa državnim dugom SAD-a je ta što vlada poseduje štampariju potrebnu za njegovu otplatu.
Kao rezultat toga, kada vlada duguje novac, oni samo pozajme još više novca da bi otplatile taj dug, povećavajući nacionalni dug.
Ako vam ovo zvuči kao Ponzijeva piramidalna šema, to je zato što ona to i jeste – najveća Ponzijeva šema u istoriji. Kao i svaka Ponzijeva šema, nastaviće se sve dok su ljudi koji kupuju Ponzijevu šemu budu uvereni da će im biti plaćeno nazad.
Ako ljudi i nacije prestanu da se zadužuju i koriste američke dolare jer nemaju poverenja u američku vladu ili vide da cena robe raste (tj. dolar postaje sve manje vredan), potražnja za dolarom će opadati, što će izazvati začaranu spiralu.
Ova spirala često završi u hiperinflaciji, kao što smo videli u novijoj istoriji sa Jugoslavijom, Venecuelom, Argentinom, Zimbabveom i mnogim drugim državama.
Ovo je način kako funkcioniše novac na vašem bankovnom računu. Novac svake nacije na svetu pati od istih problema kao i perle i novčanice u pričama o Njutoniji i Kejnslandu.
Kako banke i vlade kradu tvoj novac?
Tokom vekova, stigli smo do monetarnog sistema u kojem banke i vlade mogu da štampaju novu valutu za finansiranje svojih operacija i svojih prijatelja u zločinu, dok kradu bogatstvo svojih građana.
Šta će se desiti sa svetom kada novac bude mogao da štampa svaki narod na planeti?
- Bogatstvo onih koji su blizu pravljenja nove valute se povećava
- Vlada i politički povlašćena klasa ljudi, imaju pristup novoštampanom novcu pre svih ostalih, pa mogu da ga potroše pre nego što cene porastu. Na ovaj efekat pokazao je ekonomista Richard Cantillon sredinom 1700-ih i poznat je kao Cantillonov Efekat.
- Cena robe raste (poznato kao inflacija
- Ne raste sve roba istovremeno u ceni. Roba blizu mesta gde se proizvodi nova valuta – finansijski sektor i vlada – prva raste, i odatle uzrokuje efekt talasa na cene.
- Inflacija se često predstavlja kao promena cene potrošačke korpe, poznata kao Indeks Potrošačkih Cena, eng. Consumer Price Index (CPI). Vlada ima alate za manipulisanje ovim brojem kako bi osigurala da se ona čini niskom i stabilnom, kao što je objašnjeno u našem članku o inflaciji.
- Finansijska imovina često primećuje ogromnu inflaciju, ali bankari to ne nazivaju inflacijom – oni kažu da naša ekonomija cveta! Nakon što su američke Federalne rezerve učetvorostručile ponudu američkih dolara u šest godina nakon finansijske krize 2008. godine, banke koje su dobile te nove dolare, kupile su akcije i obveznice, stvarajući ogroman balon u cenama ove imovine.
- Štednja i životni standard stanovništva se smanjuju
- Plate su jedna od poslednjih “cena” u ekonomiji koja se prilagođava, jer se često povećavaju samo jednom godišnje. U međuvremenu, cene dnevnih potrepština te osobe koja zaradjuje platu neprestano rastu kako novi novac kruži ekonomijom.
- Najviše su pogođeni oni koji žive od plate do plate – a to je 70% Amerikanaca.
- Razlike u prihodima između bogatih i siromašnih se povećavaju, kao što se vidi na grafikonu ispod.
*Koncentracija dohotka na vrhu naglo je porasla od 1970-ih
Zašto i dalje imamo isti monetarni sistem?
Ako ovaj sistem bogate još više obogaćuje, a siromašne još više osiromašuje, dovodeći do političke nestabilnosti, zašto ga onda ne bismo promenili?
Najveći razlog zašto se ništa ne menja je verovatno to što puno toga ne znamo o samom sistemu. Svi svakodnevno koristimo valute svojih vlada, ali većina nas ne razume kako sistem funkcioniše i šta on čini našim društvima.
Obrazovni sistem, mediji i finansijski stručnjaci neprestano nam govore da je monetarni sistem previše komplikovan da bi ga normalni ljudi razumeli. Mnogi od nas se zato i ne trude da pokušaju.
Još nekoliko razloga zašto ovaj sistem nastavlja da opstaje:
- Mnogo je ljudi koji imaju direktnu korist od štampanja novog novca.
- Ti ljudi ne žele nikakve promene i bore se da zadrže tu moć.
- Nacionalne valute su često pogodne
- Kreditne kartice, online bankarstvo i još mnogo toga čine upravljanje nacionalnim valutama i njihovo trošenje lakim i jednostavnim.
- Građani moraju da plaćaju porez u svojoj nacionalnoj valuti
- To stvara potražnju za tom valutom od svih građana, povećavajući njenu vrednost.
- Glavna međunarodna tržišta, poput nafte, denominirana su u dolarima.
- Nafta je potrebna svakoj zemlji na planeti, ali pošto mnogi ne mogu da je proizvode, moraju da je kupuju na međunarodnim berzama. Od 1970-ih na ovim berzama gotovo sva nafta se prodaje za dolare, što stvara potražnju za dolarima. Da bi se odmaknule od ovog sistema, zemlje bi trebale da pronađu novu valutu ili robu za trgovinu naftom, što zahteva vreme i rizike.
- Nije postojala dobra alternativa
- Uz globalnu ekonomiju u realnom vremenu, naš sistem digitalnog bankarstva koji koristi nacionalne valute je pogodan. Transakcija u tvrdom novcu poput zlata bila bi previše nezgrapna za današnji svet. Digitalna valuta pod nazivom Bitcoin, predstavljena 2009. godine, je rastuća alternativa koja nudi čvrst novac koji se kreće brzinom interneta.
Šta je novac, i zašto trebate da brinete?
Novac je alat koji olakšava razmenu dobara. Kao i svako drugo dobro, novac se pridržava zakona ponude i potražnje – povećanje potražnje povećaće njegovu vrednost, a povećanje ponude smanjiće njegovu vrednost.
Na ovaj način novac se ne razlikuje od kuće ili piletine. Međutim, velika prodajnost novca znači da je potražnja za njim uvek velika. Kao rezultat, novac mora biti težak za proizvodnju (a samim tim i ograničen u ponudi) ili će ga onaj ko ga može napraviti, stvoriti toliko, da vremenom više neće služiti kao zaliha vrednosti. Uskoro će izgubiti svoje funkcije kao sredstvo razmene i obračunske jedinice.
Najbolji novac u datoj ekonomiji je onaj koji se najslobodnije kreće – svi ga žele, lako je obaviti transakcije sa njim i koji sa vremenom dobro drži svoju vrednost. Nijedan novac nije savršen u svemu ovome, a neki ističu jednu funkciju novca na štetu drugih.
Iako se istorija ne ponavlja, ona se rimuje, a usponi i padovi monetarnih sistema imaju jasne ritmove. Uspon i pad monetarnog sistema često sledi opšti obrazac koji smo videli u pričama o agri perlama i Kejnslandu: pojavljuje se odredjenji oblik novca koji pomaže ljudima da efikasnije trguju i štede, ali na kraju gubi na vrednosti kada neko shvati kako da ga jeftino stvori u velikoj količini. Međutim, tokom dugog perioda vremena, monetarni sistemi su se poboljšali u sve tri funkcije novca.
Na primer, zlato je tokom vremena dobro služilo kao zaliha vrednosti. Međutim, naša međusobno povezana ekonomija ne bi mogla efikasno da funkcioniše ako bi trebalo da fizičko zlato zamenimo robom i uslugama. Mnogo je lakše kretati se na papirnom i digitalnom novcu, ali istorija nam govori da su vlade i bankari iskoristili ove oblike novca za krađu bogatstva putem inflacije.
Današnji globalni monetarni sistem je vrlo zgodan, a digitalna plaćanja i kreditne kartice olakšavaju trošenje novca. Ovo skriva stalnu inflaciju koja nagriza vrednost svake jedinice novca i dovodi do sve većeg jaza u bogatstvu.
Nadam se da je ovaj članak proširio vaše razumevanje novca i njegove uloge u društvu. Ovo je samo početak svega što treba istražiti o novcu: za kasnije su sačuvane teme o inflaciji, kamatnim stopama, pozajmljivanju, poslovnim ciklusima i još mnogo toga.
Efikasnija Ušteda Novca
Možda se pitate kako zaštititi svoju štednju kada svaki oblik često korišćenog novca i investicija pati od inflacije ponude – koja umanjuje vrednost i prenosi bogatstvo onima koji mogu da stvore novac ili investiciju. Možda se čini da se ništa na planeti danas ne može kvalifikovati kao ‘težak’ novac, ali dve stvari ipak ostaju: zlato i njegov noviji rođak Bitcoin. Obe ove stvari je neverovatno teško proizvesti, a jedna od njih se kreće brzinom interneta i može se čuvati u vašem mozgu.

If you have a functioning brain, it’s impossible to fully stand for any politician or align completely with any political party. The solutions we need are not found in the broken systems of power but in individual actions and local initiatives. Voting for someone may be your choice, but relying solely on elections every few years as a form of political activism is a losing strategy. People around the world have fallen into the trap of thinking that casting a ballot once every four years is enough, only to return to complacency as conditions worsen. Voting for the "lesser of two evils" has been the norm for decades, yet expecting different results from the same flawed system is naive at best.
The truth is, governments are too corrupt to save us. In times of crisis, they won’t come to your aid—instead, they will tighten their grip, imposing more surveillance, control, and wealth extraction to benefit the oligarch class. To break free from this cycle, we must first protect ourselves individually—financially, geographically, and digitally—alongside our families.
Then, we must organize and build resilient local communities. These are the only ways forward. History has shown us time and again that the masses are easily deceived by the political circus, falling for the illusion of a "savior" who will fix everything. But whether right, center, or left, the story remains the same: corruption, lies, and broken promises. If you possess a critical and investigative mind, you know better than to place your trust in politicians, parties, or self-proclaimed heroes. The real solution lies in free and sovereign individuals who reject the herd mentality and take responsibility for their own lives.
From the beginning of time, true progress has come from individuals who think for themselves and act independently. The nauseating web of politicians, billionaires, and oligarchs fighting for power and resources has never been—and will never be—the answer to our problems. In a world increasingly dominated by corrupted governments, NGOs, and elites, ordinary people must take proactive steps to protect themselves and their families.

Governments and central banks have long manipulated fiat currencies, eroding wealth through inflation and bailouts that transfer resources to the oligarch class. Bitcoin, as a decentralized, censorship-resistant, and finite currency, offers a way out. Here’s what individuals can do:
-
Adopt Bitcoin as a Savings Tool: Shift a portion of your savings into Bitcoin to protect against inflation and currency devaluation. Bitcoin’s fixed supply (21 million coins) ensures it cannot be debased like fiat money.
-
Learn Self-Custody: Store your Bitcoin in a hardware wallet or use open-source software wallets. Avoid centralized exchanges, which are vulnerable to government seizure or collapse.
-
Diversify Geographically: Hold assets in multiple jurisdictions to reduce the risk of confiscation or capital controls. Consider offshore accounts or trusts if feasible.
-
Barter and Local Economies: In times of crisis, local barter systems and community currencies can bypass failing national systems. Bitcoin can serve as a global medium of exchange in such scenarios.
2. Geographical Flexibility: Reducing Dependence on Oppressive Systems
Authoritarian regimes thrive on controlling populations within fixed borders. By increasing geographical flexibility, individuals can reduce their vulnerability:
-
Obtain Second Passports or Residencies: Invest in citizenship-by-investment programs or residency permits in countries with greater freedoms and lower surveillance.
-
Relocate to Freer Jurisdictions: Research and consider moving to regions with stronger property rights, lower taxes, and less government overreach.
-
Decentralize Your Life: Avoid keeping all your assets, family, or business operations in one location. Spread them across multiple regions to mitigate risks.
3. Digital Privacy: Fighting Surveillance with Advanced Tools
The rise of mass surveillance and data harvesting by governments and corporations threatens individual freedom. Here’s how to protect yourself:
-
Use Encryption: Encrypt all communications using tools like Signal or ProtonMail. Ensure your devices are secured with strong passwords and biometric locks.
-
Adopt Privacy-Focused Technologies: Use Tor for anonymous browsing, VPNs to mask your IP address, and open-source operating systems like Linux to avoid backdoors.
-
Reject Surveillance Tech: Avoid smart devices that spy on you (e.g., Alexa, Google Home). Opt for decentralized alternatives like Mastodon instead of Twitter, or PeerTube instead of YouTube.
-
Educate Yourself on Digital Privacy: Learn about tools and practices that enhance your online privacy and security.
4. Building Resilient Local Communities: The Foundation of a Free Future
While individual actions are crucial, collective resilience is equally important. Governments are too corrupt to save populations in times of crisis—history shows they will instead impose more control and transfer wealth to the elite.
To counter this, communities must organize locally:
-
Form Mutual Aid Networks: Create local groups that share resources, skills, and knowledge. These networks can provide food, medical supplies, and security during crises.
-
Promote Local Economies: Support local businesses, farmers, and artisans. Use local currencies or barter systems to reduce dependence on centralized financial systems.
-
Develop Off-Grid Infrastructure: Invest in renewable energy, water filtration, and food production to ensure self-sufficiency. Community gardens, solar panels, and rainwater harvesting are excellent starting points.
-
Educate and Empower: Host workshops on financial literacy, digital privacy, and sustainable living. Knowledge is the most powerful tool against authoritarianism.
5. The Bigger Picture: Rejecting the Illusion of Saviors
The deep corruption within governments, NGOs, and the billionaire class is evident. These entities will never act in the interest of ordinary people. Instead, they will exploit crises to expand surveillance, control, and wealth extraction. The idea of a political “savior” is a dangerous illusion. True freedom comes from individuals taking responsibility for their own lives and working together to build decentralized, resilient systems.
Conclusion: A Call to Action
The path to a genuinely free humanity begins with individual action. By adopting Bitcoin, securing digital privacy, increasing geographical flexibility, and building resilient local communities, ordinary people can protect themselves against authoritarianism. Governments will not save us—they are the problem. It is up to us to create a better future, free from the control of corrupt elites.

2025-04-02 12:02:45We value sovereignty, privacy and security when accessing online content, using several tools to achieve this, like open protocols, open OSes, open software products, Tor and VPNs. ## The problem Talking about our social presence, we can manually build up our follower list (social graph), pick a Nostr client that is respectful of our preferences on what to show and how, but with the standard following mechanism, our main feed is public, **so everyone can actually snoop** what we are interested in, and what is supposable that we read daily. ## The solution Nostr has a simple solution for this necessity: encrypted lists. Lists are what they appear, a collection of people or interests (but they can also group much other stuff, see [NIP-51](https://github.com/nostr-protocol/nips/blob/master/51.md)). So we can create lists with contacts that we don't have in our main social graph; these lists can be used primarily to create **dedicated feeds**, but they could have other uses, for example, related to monitoring. The interesting thing about lists is that they can also be **encrypted**, so unlike the basic following list, which is always public, we can hide the lists' content from others. The implications are obvious: we can not only have a more organized way to browse content, but it is also **really private one**. One might wonder what use can really be made of private lists; here are some examples: - Browse “can't miss” content from users I consider a priority; - Supervise competitors or adversarial parts; - Monitor sensible topics (tags); - Following someone without being publicly associated with them, as this may be undesirable; The benefits in terms of privacy as usual are not only related to the casual, or programmatic, observer, but are also evident when we think of **how many bots scan our actions to profile us**. ## The current state Unfortunately, lists are not widely supported by Nostr clients, and encrypted support is a rarity. Often the excuse to not implement them is that they are harder to develop, since they require managing the encryption stuff ([NIP-44](https://github.com/nostr-protocol/nips/blob/master/51.md)). Nevertheless, developers have an easier option to start offering private lists: give the user the possibility to simply **mark them as local-only**, and never push them to the relays. Even if the user misses the sync feature, this is sufficient to create a private environment. To date, as far as I know, the best client with list management is Gossip, which permits to manage **both encrypted and local-only lists**. Beg your Nostr client to implement private lists!

2025-05-16 20:57:43Google says that Android 16 is slated to feature an optional high security mode. Cool.
Advanced Protection has a bunch of requested features that address the kinds of threats we worry about.
It's the kind of 'turn this one thing on if you face elevated risk' that we've been asking for from Google.
And likely reflects some learning after Google watched Apple 's Lockdown Mode play out. I see a lot of value in this..
Here are some features I'm excited to see play out:
The Intrusion Logging feature is interesting & is going to impose substantial cost on attackers trying to hide evidence of exploitation. Logs get e2ee encrypted into the cloud. This one is spicy.
The Offline Lock, Inactivity Reboot & USB protection will frustrate non-consensual attempts to physically grab device data.
Memory Tagging Extension is going to make a lot of attack & exploitation categories harder.
2G Network Protection & disabling Auto-connect to insecure networks are going to address categories of threat from things like IMSI catchers & hostile WiFi.
I'm curious about some other features such as:
Spam & Scam detection: Google messages feature that suggests message content awareness and some kind of scanning.
Scam detection for Phone by Google is interesting & coming later. The way it is described suggests phone conversation awareness. This also addresses a different category of threat than the stuff above. I can see it addressing a whole category of bad things that regular users (& high risk ones too!) face. Will be curious how privacy is addressed or if this done purely locally. Getting messy: Friction points? I see Google thinking these through, but I'm going to add a potential concern: what will users do when they encounter friction? Will they turn this off & forget to re-enable? We've seen users turn off iOS Lockdown Mode when they run into friction for specific websites or, say, legacy WiFi. They then forget to turn it back on. And stay vulnerable.
Bottom line: users disabling Apple's Lockdown Mode for a temporary thing & leaving it off because they forget to turn it on happens a lot. This is a serious % of users in my experience...
And should be factored into design decisions for similar modes. I feel like a good balance is a 'snooze button' or equivalent so that users can disable all/some features for a brief few minute period to do something they need to do, and then auto re-enable.
Winding up:
I'm excited to see how Android Advanced Protection plays with high risk users' experiences. I'm also super curious whether the spam/scam detection features may also be helpful to more vulnerable users (think: aging seniors)...
Niche but important:
Some users, esp. those that migrated to security & privacy-focused Android distros because of because of the absence of such a feature are clear candidates for it... But they may also voice privacy concerns around some of the screening features. Clear communication from the Google Security / Android team will be key here.

2025-05-16 19:26:56This article was originally part of the sermon of Plebchain Radio Episode 111 (May 2, 2025) that nostr:nprofile1qyxhwumn8ghj7mn0wvhxcmmvqyg8wumn8ghj7mn0wd68ytnvv9hxgqpqtvqc82mv8cezhax5r34n4muc2c4pgjz8kaye2smj032nngg52clq7fgefr and I did with nostr:nprofile1qythwumn8ghj7ct5d3shxtnwdaehgu3wd3skuep0qyt8wumn8ghj7ct4w35zumn0wd68yvfwvdhk6tcqyzx4h2fv3n9r6hrnjtcrjw43t0g0cmmrgvjmg525rc8hexkxc0kd2rhtk62 and nostr:nprofile1qyxhwumn8ghj7mn0wvhxcmmvqyg8wumn8ghj7mn0wd68ytnvv9hxgqpq4wxtsrj7g2jugh70pfkzjln43vgn4p7655pgky9j9w9d75u465pqahkzd0 of the nostr:nprofile1qythwumn8ghj7ct5d3shxtnwdaehgu3wd3skuep0qyt8wumn8ghj7etyv4hzumn0wd68ytnvv9hxgtcqyqwfvwrccp4j2xsuuvkwg0y6a20637t6f4cc5zzjkx030dkztt7t5hydajn
Listen to the full episode here:
<<https://fountain.fm/episode/Ln9Ej0zCZ5dEwfo8w2Ho>>
Bitcoin has always been a narrative revolution disguised as code. White paper, cypherpunk lore, pizza‑day legends - every block is a paragraph in the world’s most relentless epic. But code alone rarely converts the skeptic; it’s the camp‑fire myth that slips past the prefrontal cortex and shakes hands with the limbic system. People don’t adopt protocols first - they fall in love with protagonists.
Early adopters heard the white‑paper hymn, but most folks need characters first: a pizza‑day dreamer; a mother in a small country, crushed by the cost of remittance; a Warsaw street vendor swapping złoty for sats. When their arcs land, the brain releases a neurochemical OP_RETURN which says, “I belong in this plot.” That’s the sly roundabout orange pill: conviction smuggled inside catharsis.
That’s why, from 22–25 May in Warsaw’s Kinoteka, the Bitcoin Film Fest is loading its reels with rebellion. Each documentary, drama, and animated rabbit‑hole is a stealth wallet, zipping conviction straight into the feels of anyone still clasped within the cold claw of fiat. You come for the plot, you leave checking block heights.
Here's the clip of the sermon from the episode:

2025-05-24 15:55:20It wasn’t so long ago that the mainstream conversation around population was exclusively focused on the dangers of overpopulation. The fatal flaws in the Malthusian theory had yet to be disproven clearly and obviously by observable demographic trends. That’s been gradually changing, and while it’s hardly a mainstream consensus, concerns about falling birthrates and the risk of population collapse have taken over the population conversion on the political right, and sometimes beyond.
There’s no questioning the data at this point. Fertility rates over most of the world have been in precipitous decline, and if the current trajectory continues, global population will peak very soon and fall rather dramatically. And even the falling population itself is much less of a threat than the aging population that will inevitably precede it. Having a large cohort of older and retired people and a small cohort of young workers is an existential threat to the modern welfare state, and to the entire credit-based fiat monetary system that supports it. But that’s a subject for another day.
There are a multitude of different theories that attempt to explain why this is happening. I’ll name some of the most common ones:
-
Increased education and employment opportunities for women
-
Urbanization
-
Economic factors
-
Access to contraception
-
Changing social and cultural norms
-
Delayed marriage
-
Improvements in infant mortality rates
-
Government policies
-
Environmental concerns
-
Pornography
-
Feminism
-
Endocrine disrupting chemicals
-
Dating apps
Most rational thinkers agree there must be multiple factors playing a role. But the fact that the problem is so wide-spread, and populations that seem to be resisting the trend are so rare, shows that the strongest underlying factors are cross-culturally powerful and not easily resisted or reversed with marginal cultural differences and standard public policy efforts.
While populations that resist the trend are rare, they are not quite non-existent. A few groups stand out for their persistently high fertility rates. On a geographic basis, sub-Saharan Africa is the only major region still maintaining above-replacement fertility rates. For various reasons, I don’t think Africa is the most useful place to look for answers on what’s causing the decline elsewhere or how it could be reversed. One reason is that Africa seems to be following the global pattern, just with a lag. In another few decades the data may look very different, just like it does for South America today compared to 20 years ago.
In my opinion, a more useful place to look for data is in smaller population sub-groups within a geographic area that have fertility rates significantly higher than the general population levels. Rural populations in general have higher fertility rates than urban populations, but the difference isn’t really enough to consider it significant. The groups that fit this category well seem to be exclusively religious. These include certain Christian denominations in the traditional Anabaptist category including the Amish, Mennonites, and Hutterites, Muslims in some areas, and Jews, particularly the most orthodox sects. Mormons recently fell out of the high-fertility religious group category, which would also make for some interesting research.
It would be fascinating to compare these groups and see what they have in common outside just being religious in nature. I don’t have the knowledge to make that comparison. Instead, I’m going to focus on the group that’s often referenced and analyzed by people without much personal knowledge, the Amish.
I have read numerous articles and comments that reference the Amish to support this or that theory on the cause of falling fertility. One thing I notice is an obvious lack of understanding of the Amish culture, which leads to faulty arguments that don’t reflect reality. This isn’t surprising, given the insular and poorly-understood nature of the culture, the plethora of ridiculously incorrect “Amish” reality TV shows and pop culture myths, and the fact that the number of people with firsthand knowledge of Amish culture from an insider perspective who also write about demographic trends on any public platform is probably zero.
Well, was zero. I’m about to make that one.
My Qualifications
Since I’m claiming to have this knowledge, it’s only fair to give a little background as to how I got it. I choose to stay anonymous on the internet, and given that this is personal information that could make it significantly easier to dox me, I’ll be deliberately vague.
My parents were both born in Amish families. They didn’t stay, opting to leave the Amish church and culture before getting married and starting their family. My grandparents were all Amish, and all my cousins and most of my extended family remain Amish to this day. My parents didn’t move out of the Amish community, staying in the area and joining a conservative Mennonite church that was about the closest thing to being Amish without actually being Amish. The Mennonite community has a generally good relationship with and a lot of respect for the Amish community, given their deep similarities and shared history and cultural background.
I grew up interacting regularly with Amish relatives, neighbors and community members, speaking the Pennsylvania Dutch my parents taught us and used exclusively at home. I’m very certain that a real deep understanding of Amish culture is almost impossible without speaking their language, just like many other cultures around the world. The Amish speak English as their second language, but there are aspects of their culture that aren’t spoken about in English.
This lifelong proximity to and interaction with the Amish community has, I believe, given me some unique insights into the factors supporting their high fertility rates that no amount of academic research will ever uncover.
Who are the Amish?
First, some basics.
The Amish are a traditionalist Christian denomination. The way to understand the Amish is as a religious denomination first, and a culture second. Getting the two mixed up makes it impossible to understand why the Amish live the way they do.
Sure, their unique lifestyles makes them noteworthy as a group. But that lifestyle is based on and maintained by their religious beliefs and convictions.
Fundamentally, the Amish attempt to live out the Gospel as Jesus taught in the Sermon on the Mount. They believe their church has done so historically, and that the best way to make sure they keep doing so in the future is to view any changes to their traditional lifestyle with extreme skepticism and resistance.
The two primary doctrines that separate them from the mainstream Protestant Reformation, which is their group’s origin, are the doctrines of nonconformity and nonresistance. They apply the doctrine of nonconformity, the command to “be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God” in both a spiritual and a practical sense. They believe that Christians are to be radically different from non-Christians, both in their beliefs and attitudes, and in their lifestyle and appearance. And they apply the command to “resist not evil”, nonresistance, to mean that it’s a sin to use physical force or violence against another person for any reason whatsoever. They don’t make any exception for military service of any type, which they object to as a matter of conscience, or for self-defense, which they refuse to engage in even if it means death for themselves or their family.
The Amish do not practice infant baptism. Their young people must choose to be baptized and formally become members of the church, usually in their late teens or early twenties. As part of the baptism ceremony, they make a vow to remain faithful to God and the church until death. The Amish, as a church, interpret this vow to mean that the new church member will remain a member of the Amish church for life. Leaving the Amish church after making this vow and being baptized is viewed as breaking the vow, and is the justification for their practice of shunning, or the ban. Those who do so are cut off from contact with the community in various ways. Typically they won’t eat a meal with a shunned person, ride in a car a shunned person is driving, or do business with a shunned person. That includes immediate family. Failure to enforce this shunning against someone, even your own child, can result in running afoul of the church leadership and also being excommunicated and shunned.
This punishment, however, only applies to people who leave the church after baptism. Those young people who choose not to be baptized and leave the church instead are free to be treated just like any other non-Amish person, although their family essentially disown them and treat them like a shunned person anyway, if they’re especially strict and upset about the betrayal of Amish values.
Most Amish people don’t believe that the Amish are the only true church, or that only Amish people are true Christians. Most are accepting of other conservative Anabaptist denominations, and respect their values and practices as a different but valid way to be Christian. Church teaching strongly suggests that those who fall under the ban are living in sin and won’t make it to heaven. Most individuals, though, probably wouldn’t agree with that in every case if they were free to give their true opinion on the issue.
The Amish maintain a fertility rate of around 6 to 7 children per woman. Some recent research suggests this may be starting to fall somewhat, but the data isn’t extensive enough to make a solid judgement yet.
There are a wide variety of different “flavors” of Amish in different areas of the US, a fact they’re very aware of. The data strongly indicates that the most conservative and technologically primitive communities have slightly higher fertility rates and significantly higher retention rates of young people.
Why do the Amish Maintain High Fertility Rates?
Okay, enough background. Time to dive into the reasons I believe the Amish maintain their historically high fertility rate despite living in a developed, modern economy surrounded by people with dramatically sub-replacement fertility rates.
I thought long and hard about the best way to approach this. Going through a list of factors topically seemed like the obvious one. But the more I thought it through, the less I liked it. For one, how do you arrange the factors? Order of importance? How do you decide that? Also, the factors are so inter-related that they’ll be very tough to separate and understand individually. Finally, it seems dry and boring. Nobody needs that.
So I’m going to try something different. I’m going to approach it from a narrative angle. I’ll try to describe the life of a typical Amish person, from birth to death, in a chronological way. That’s the best approach to present it in a way that makes the culture relatable, while also tying the different factors together logically.
I’ll describe the experience for both men and women as best I can, and try to present the various factors encouraging high fertility as I see them at the appropriate part of the story.
This will likely be an article that gets revised later to address any questions that come up, so don’t consider it the final word on the subject.
Alright, time to get started.

First off, this might seem obvious, but the typical Amish baby is born into a large family. On average, they’ll have 5 or 6 siblings, and more is not at all uncommon. Families of 10 won’t raise an eyebrow, and 12-16 children aren’t unheard of, especially in the past when mortality was higher and second marriages were more common among younger widowers who went on to have children with their second wife. Humans are social creatures, and the environment and people we grow up surrounded by have a strong influence on our frame of reference. Studies have shown that women are very unlikely to have more children than their mother had. The number of siblings in your family, and in families you observe and interact with, doesn’t determine the number of children you will have, but it does strongly influence the number of children you feel is a “normal” amount. That makes it a kind of ratchet effect, where it’s very unlikely that a generation raised in homes with one or two children will go on to have larger families of their own collectively.
This cultural norm of large families establishes a kind of inertia that normalizes high fertility right from birth. Amish children grow up surrounded by siblings, observing, and as they get older, helping with the care and maintenance of a large family. All their relatives, cousins and extended family are also likely to belong to large families. The average Amish child grows up with dozens of first cousins, and sometimes hundreds of more distant cousins, many of whom they likely know well and socialize with regularly. This experience establishes a mental framework where a large family is assumed to be the default. And there is no stronger human tendency than the urge to fit in with the people around you.
Amish children grow up with strong gender norms taught from a very young age. The Amish culture follows strict and conservative gender roles. Boys and men do male things, girls and women do female things, and there is little effort or desire to create any overlapping space.
Boys grow up doing traditionally masculine things. They play outside, do chores on the farm, help their dad with his work, probably get a BB gun before age 10, go hunting and fishing, play sports, and generally prepare for a lifetime of physical labor and providing for a wife and family.
Girls grow up doing traditionally feminine things. They help care for younger siblings, help with housework, play with dolls, learn to cook and preserve food, learn to sew, and generally prepare for a lifetime of caring for and raising children and maintaining a large household.
It’s a common misconception that the Amish are mostly farmers who live off the land, subsistence style. That’s not at all accurate. While there are still Amish who make their living farming, at least in some areas, that has become the exception. The large scale of modern agriculture means it takes a lot of acres and a lot of machinery to run a profitable commercial farming operation. The Amish reject the use of most modern agricultural machinery, which makes them uncompetitive in commercial agriculture outside more niche markets like dairy, produce, or greenhouses. And the fact that they live in small geographic communities with large families means they quickly buy up all available farmland in an area until they price themselves out of the market. Prime farmland in heavy Amish farming communities like Lancaster, Pennsylvania routinely sells for over $25,000 per acre, which is more than a commercial crop farming operation might bring in over a lifetime.
So the Amish have moved away from a primarily agriculture based economy to various other occupations. In some areas they work in RV factories. Most work in trades, primarily construction. Many are masons, carpenters, cabinet builders, mechanics, welders, etc.
But they reject the ownership of cars, so they still use their characteristic horses and buggies for transportation. In reality, they use cars for most of their transportation needs. But they don’t own cars or have driver’s licenses, so they rely on “Amish taxi drivers” to chauffer them around. The men hire a driver to take them to and from work, if they work in construction or some other job outside the home. The women hire a driver take them to town for their shopping or for other errands. The exception is church. They’re still required to drive to church in a horse and buggy, so every family must keep a horse for that reason, as a bare minimum. In many cases that’s the only time they ever use a horse and buggy, and if it weren’t for that requirement they wouldn’t own one at all.
But that requirement means every Amish family must own enough land to keep a horse, which takes a few acres and a small barn at minimum. This forces them to live in rural areas and raise their families in a somewhat agricultural environment, even if their occupation wouldn’t require that at all. So there are always chores for the children, animals to care for, and space to play outside with their siblings.
Amish children grow up with very limited exposure to mainstream cultural pressures. Their mothers inevitably raise them at home until they start school. They don’t have TV or cell phones, so they aren’t exposed to any mainstream culture on a daily basis.
The Amish have their own schools, typically small one room schools within walking distance of all the families who attend. The teachers are often young single people, always Amish. They primarily teach basic academics: reading, writing, arithmetic, geography, history, etc. While the Amish speak both English and Pennsylvania Dutch, many Amish children are first exposed to English on a daily basis when they start school. School is taught in English, although there is limited teaching of the High German the Amish use in their church services.
Amish children attend school until 8th grade. The schools run the minimum number of days required by the state, usually 160. There is no higher education beyond grade 8. No Amish attend college.
Amish children are taught from little up that they are not like other people. The differences between their culture and mainstream culture are emphasized, and Amish culture is praised as the ideal, at a religious level. They're taught that the way to do what’s right is to do what the church asks, and those who don’t do what the church asks are in the wrong.
The Amish rate and describe everyone on a scale from “high” to “low”. A person who isn’t Amish, who isn’t a Christian, is a “high” person, or an “English” person. To go from being Amish to being “English” is the worst, most damning, failure imaginable. The Amish are “low” people. The more strict and traditional an Amish sect, the “lower” they are. Being “low” is seen as a virtue. Other conservative Christian denominations, particularly other Anabaptist groups, are also considered “low” people and generally viewed favorably, but they aren’t as “low” as the Amish.
Amish boys grow up expecting to start work full time at age 14, and to work at some type of trade or physical labor. There are no white-collar career tracks, essentially. Entrepreneurship is encouraged, and many young Amish men start their own construction crew or home business in their 20s or 30s after a few years of experience working for someone else. Often Amish boys start off working for and with their dad, in whatever trade or business he operates. But if they’re not interested in that particular occupation, they’re free to find another. Amish businesses and tradesmen are always willing to hire young Amish boys and train them in a craft. A good work ethic is considered a virtue, and Amish are known for their skilled craftsmanship and willingness to work harder than the competition. These traits are taught and encouraged from little on up.
Amish men as a whole do very well financially. For one, they start working and developing skills and work ethic a decade earlier than the typical college graduate. The trades pay well, and of course anyone could take advantage of that, but the mainstream narrative discourages men from pursuing a trade career by labeling it low status and keeping them in education until their prime years to gain a work ethic are past. It’s not uncommon for young Amish men just out of 8th grade to land a job on a carpentry crew for $25-30 an hour. With bonuses, some of them are bringing in $90k/year before age 20. Another advantage young Amish men have is lower expenses. They can certainly find places to spend their money, typically hobbies like hunting and fishing, but things like expensive designer clothes and accessories or overpriced car payments aren’t really an option. They also benefit from the Amish exemption to Social Security taxes. The Amish don’t pay into or collect Social Security. More on that later, but it helps immensely to keep more of your paycheck in your early prime working years.
Amish girls grow up expecting to get married at a young age and raise a large family as a traditional housewife. Amish girls aren’t encouraged to have a “career”, and the idea would be silly to them. They are expected to work, but the work is either helping their mom with the household, working on the family farm or business, or doing something like teaching school or working at an Amish farmer’s market to pass the time between leaving school and marriage. It’s never viewed as a permanent occupation, because marriage and motherhood is the default aspirational lifestyle. A common job for young Amish girls is working as a “maid” to help a new mother with housework at the end of pregnancy and for the first few months after childbirth. All new mothers can get this type of help if they want, and it will usually be a younger sister, cousin, or niece of appropriate age. Otherwise the community will find a suitable girl who’s available for the job. A “maid” will sometimes travel to a different Amish community for this reason, given how large extended families are and how frequently Amish families move across the country to a different community. This is often an opportunity for them to attract the attention of a young man outside their local community, and is one of the only ways for a long-distance relationship and marriage to begin.
Amish young people are expected to live with their parents until marriage, with very few exceptions. They’re also typically expected to work for their dad in the family business for no pay, and to give any earnings they make at a day job outside the home to their parents. This is typically expected until age 21, or until they get married, whichever comes first. More recently, with the rising cost of land and housing, it’s becoming more common to make age 18 the cutoff. And when a young couple is engaged, the parents typically allow them to start saving their income for their future household. This practice helps parents offset some of the expenses of raising such large families, along with the fact that no money is spent on higher education. It also provides one strong incentive to marry as early as possible.
Amish culture revolves around family and the community. Extended families are large, and people are expected to know and interact with their family. Conversation with a stranger at a social event invariably starts by asking their name, then asking who their parents, grandparents, and other relatives are until some distant family connection or a mutual acquaintance is found. Since the Amish community has a small pool of family names, and tends to heavily favor certain Biblical first names, enough people end up with the same name to make things really confusing. People are often identified by two or three generations of their family, for example “Sam Yoder’s John’s Amos” for an Amos Yoder who’s father was John Yoder and grandfather Sam Yoder.
Social activities are either family events or church events, or both. Weddings and funerals are the main social functions other than church services, and people are expected to attend as many as possible among their family and extended family, regardless of the distance. Given the large family sizes, most Amish have dozens of first cousins and many more distant cousins. Weddings and funerals can be almost weekly events. These are church events as well, so much of the local Amish community will usually attend. It will be an all day event, with the women and girls preparing a lunch and dinner for everyone. After the meal, the women and girls will wash the dishes and clean up, while the men sit around and talk. No cell phones, remember. Talking is the main form of social interaction. Topics typically include work, family news, hunting and fishing stories (Amish men hunt and fish with the same enthusiasm typical American men watch sports), horses, and interesting or funny stories about family and friends. Those with a knack for entertaining oratory are well respected and appreciated in the Amish community.
Of course the women do their fair share of talking as well, in the kitchen while cleaning up after the meal, and later in the living room where they join the men after the domestic work is done. The main topics of conversation always revolve around family, immediate and extended. News travels through the Amish community faster than any social media platform, because nothing builds Amish female status more than being the first to call with the news that great uncle so-and-so was injured in a farming accident or nephew so-and-so has a new baby, along with all the pertinent details about the name, size, and health of the baby and how the mother is doing and how many grandchildren that makes in total for the lucky grandparents.
While the adults are talking, the children are free to play either inside or preferably outside. Trampolines, climbing trees, playing in the hayloft, tag, volleyball, and softball are favorite activities at various ages. The younger boys and girls typically play together, but as they get older the girls spend more time visiting while the boys prefer more structured sports. Softball is a game for boys, but volleyball is popular with mixed teams of boys and girls at any age.
Visiting relatives or other community families is also a popular social activity, especially on “in-between Sunday”. The Amish have church every other week, and the week without church is often an opportunity to visit another family. Invitations are not expected or required, and anyone stopping by will be expected to stay for dinner and into the evening. At these type of events, the older children are often expected to sit and visit with the adults. Sitting still and being quiet are mandatory skills, since church services are 2 hours or longer and held in barns or sheds without air conditioning filled with backless wooden benches. Self-discipline is not an optional virtue, because the alternative is physical discipline.
As Amish young people enter their mid teen years, they go from childhood to youth. At a certain age, usually around 15 or 16, they officially become youth and enter the stage everyone is familiar with, “rumspringa”. That’s a Pennsylvania Dutch word that translates to “running around”. The Amish use it more as a verb, but pop culture has adopted it as a noun based on some wildly inaccurate reality TV shows and depictions.
The reality is, rumspringa varies widely from community to community, mostly based on what the parents and church leaders tolerate. Remember that Amish church membership is a fully voluntary decision, and Amish young people are free to join or not, as they decide. Late teens is the typical age for that decision. In the meantime, they are free to make their own decisions, subject to their parents’ rules. Breaking the rules can mean that at some point, they won’t be welcome to live in their parents’ household any more. That’s a fairly strong deterrent to the most extreme infractions.
At this stage, young Amish men will be buying their own horse and buggy, and both boys and girls will be permitted to attend the Sunday night “singing”. This is a social activity held at someone's house on Sunday evening, involving all the youth in the community coming together for dinner, playing volleyball, and singing German hymns together. The purpose is to provide a somewhat controlled social environment for young men and women to interact and hopefully meet their future spouse. Dating couples can attend together, and dates are permitted after the formal activities, with the young men often driving their date home late at night before finally heading home themselves.
Depending on the tolerance of the community, the informal activities can be a bit more permissive than singing hymns and playing volleyball. Often the buggies will become a typical teenage party scene, with alcohol, smoking, a radio, illicit smartphones and DVD players, and some less-than-reserved interaction between boys and girls. The punishment for getting caught can be severe, but in many cases the adults tend to turn a blind eye to what’s happening, and let the young people do as they please.
A lot more could be said about the dynamics of this cultural practice, but specifics vary so much between communities that I don’t think there’s much value in doing so. The point I think is relevant to this discussion is the question of sex.
There’s no reason to go off into the weeds on how much, if any, sex occurs. Premarital sex is absolutely forbidden. Does it happen anyway? Humans being human, certainly. How much? Probably very little in most cases. Getting pregnant, or getting someone pregnant, is the one transgression with inevitable life-changing consequences. The “shotgun wedding” is alive and well among the Amish, and getting a girl pregnant means marrying her or being expelled from the Amish community permanently, no exceptions. Besides that, getting pregnant outside of marriage is the most disgraceful and shameful thing a girl could do. It happens very very rarely, put it that way.
So casual sex within the community is basically off the table. What about casual sex with “English” people? This is where the Amish cultural practices play a big role. The Amish dress very distinctly. They can’t go anywhere in their traditional clothes without being instantly recognized. They also don’t drive cars, so going somewhere means getting a ride with someone. And their parents will usually keep an eye on their plans and whereabouts. So let’s imagine how an Amish teenager might go about finding a casual sexual encounter.
First off, getting ahold of a cell phone would be essential. They need some way to communicate with the outside world, and coordinate with their “partner in crime.” A lot of Amish teenagers do this, often with the help of slightly older people who have left the Amish, but keep ties with the community, maybe an older sibling or cousin. These are often the same people who buy alcohol for Amish teens.
Then, they need to get some non-Amish clothes. Remember, every trip away from home will take a willing driver, a plausible excuse in a community where everyone knows everyone, and the guarantee of being immediately recognized if seen in public. And the Amish parents know who the “bad kids” are, the ones who left but are willing to help their younger relatives and friends break the rules. Getting caught hanging around with them will probably mean a lot less trust and a lot less freedom in the future.
For the girls, a change of “English” clothes and a new hairstyle will let them blend in quite well. Of course, they can’t be caught leaving or coming home in those clothes, or have the clothes found at home. Lots of logistical hurdles everywhere. For the boys, they have a very distinctive haircut. A new change of clothes won’t fix that. There’s really no way for them to hide the fact that they’re Amish, even if the accent and the lack of a driver’s license don’t give them away.
Assuming they manage all that, and sneak away from home undetected, how will they find someone to hook up with? They’re very insulated from popular culture, and probably not at all comfortable in typical social situations. For the girls, there’s the added risk that an accidental pregnancy, or even just getting caught, would ruin their reputation and any chance of marriage and a family in the Amish community. So they’re unlikely to even try, unless they’re already fully intending to leave the Amish for good. That only really happens if they have a guy ready to marry them outside the Amish community, for reasons I’ll get into more later. Briefly, the Amish culture and schooling leaves women poorly prepared to support themselves outside that culture.
For the boys, there’s the typical difficulty men face in finding casual sexual partners. Multiply that by the difficulty of not having a car or driver’s license, not being experienced in mainstream social norms, plus that obvious and undisguisable Amish haircut. And all that ignores the lifelong teaching that casual sex is sinful and wrong, and those who engage in it are going against the teachings of God and the church. The entire culture is specifically designed to discourage casual sex as strongly as possible, and it does an excellent job at that.
Why does that matter? Well, humans are all very much the same, with the same desires and instincts. And sex is one of the strongest of those desires. The Amish are certainly no different.
So the Amish religious practice and culture offers a very simple choice. You can choose sex outside of marriage, which will be difficult or impossible, occasional at best, and if you get caught will mean expulsion from the community your life is rooted in, and even if you don’t get caught will mean you’re committing a mortal sin that will keep you out of heaven if you don’t repent and change. Or, you can get married and have all the sex you want, and be respected and rewarded for it.
That’s really all it takes to sell the idea of marriage to most men.
When a couple does decide to get engaged, of course with permission from the girl’s father, the wedding happens within a reasonably short time, in acknowledgement of the temptation young people face in that situation.
So let’s take a little closer look at the gender differences between the choice to stay single or to marry. It’s helpful to lay out the different life paths available, and how they play out over time.
There are very few Amish who remain single throughout their life, and almost all of them are women. So let’s look at it through a man’s perspective first. What kind of life can a single Amish man expect?
First off, a lifetime of celibacy. There’s hardly any need to go further, that’s a deal breaker for most men. If they choose to stay single for some reason, most will leave the Amish completely rather than accept those terms.
So maybe it’s more useful to look at incentives for early marriage, which is the norm. I’m a strong believer that incentives create outcomes, so I’ll be taking a hard look at incentives throughout this article.
Young people are expected to live with their parents until marriage, in most cases. Remember, no going off to college either. So from age 14 on, they’re stuck living with Mom and Dad, working full time, and not even keeping their own income. That gets old fast. Getting married, moving out, and starting a family looks better every day. Besides that, Amish women do a lot to improve the lives of their men. The Amish are well known for their delicious food. Well, that’s because the Amish women cook and bake. As a single guy, moving out of Mom’s house means not getting delicious home-cooked food every day. And they don’t have an iPhone to order DoorDash either, so it’s pizza delivery, hiring a driver to go to a restaurant, or whatever you can cook yourself. And Amish boys don’t grow up learning how to cook, that’s women’s work. Same with making clothes. Amish mothers and wives sew clothes for their families, since they’re forbidden to wear commercially available clothes in general. So a single guy is dependent on his mom for new clothes as well. Same with washing clothes. Most Amish have fairly modern clothes washing machines, although they don’t use dryers. But washing and folding clothes isn’t a job most boys grow up doing, so they’re pretty lost if they have to try it.
All in all, there aren’t a lot of upsides to staying single longer than absolutely necessary. There are plenty of benefits to marriage, though. For one, marriage is seen as a necessary step to full maturity as a man. It’s even expressed as a visible marker. Single young men typically stay clean-shaven. Once they get married, shaving is completely forbidden, and they are required to grow out a full beard. So the difference between married and single men is obvious at first glance, and is acknowledged as a marker of full maturity.
Then of course there’s the sexual access. No explanation needed.
Then there are all the benefits of an improved lifestyle a stay-at-home wife provides. That includes cooking, cleaning, washing clothes, caring for a garden, preserving food, helping with farm work or chores, and helping with his business. Many Amish wives are very involved in their husband’s career or business, whether that’s managing the bookkeeping, working in the greenhouses, or helping with daily chores on the farm. While most Amish communities use quite modern household appliances, powered with batteries, kerosene, or air pressure, the work of maintaining a household is still much more involved than for the typical American household. Especially when it comes to sewing, which very few American women do at all, but which took a large percentage of women’s time only a few generations ago. Among the Amish it still does.
I’m only focusing on the incentives for marriage right now, because that’s the first step. Of course, most married couples today don’t have 5-8 children, so there’s more to the story. But universal marriage, particularly early marriage, is an essential part of the puzzle.
Shifting focus to the women, here the picture is even more clear. Almost all lifelong single Amish people are women, and that’s not by choice. The Amish still maintain the “old maid” category that used to be part of mainstream culture. Single Amish women are almost invariably single because no man offered to marry them. Here’s why.
If single life is unappealing for Amish men, it’s positively bleak for women. Marriage and family life is the aspirational goal they’re taught from little up. And for good reason.
With their eighth-grade education, and without a driver’s license and car, their income earning potential is very limited. Most young women who aren’t busy on the farm or with the family business work as schoolteachers, housecleaners, babysitters, or cooks and servers at Amish restaurants or farmers’ markets. None of these jobs pay well. Enough to buy a few personal items, but not enough to buy a house or support even one person. And while it might be acceptable for a single Amish man to eventually buy a house and move out, at some point in his late 20s or early 30s, it’s really not acceptable at any age for an Amish old maid. Those old maids typically end up living with their parents, caring for them in old age, working the same type of jobs young girls do, and probably hoping that at some point an older widower with a family will show up and propose.
Marriage has massive lifestyle benefits for women, even more so than for men. Amish men typically do well financially, and often work in construction as well, or have friends and relatives who do. Amish houses are very nice and well constructed to say the least, and the wife gets the house she wants, the way she wants it. Being stingy with a house for your wife isn’t part of an Amish man’s mentality. Amish women are well rewarded for all their hard work keeping house, with a house they’ll be happy keeping. And of course a nice farm or at least some acreage, with space for a big garden, a barn for any animals, and space for greenhouses or whatever she needs for any home business ambitions she might have.
Along with that, Amish women have a lot of flexibility when it comes to spending money. Many Amish women handle most of the family finances. And the money her husband earns is family money, not his money. While the husband has final say in financial decisions, most Amish men don’t say no to their wives’ purchase requests often. Married Amish women have access to all the creature comforts the church allows to make their lives as pleasant as possible.
When it comes to status, the benefits are just as clear. Amish life revolves around family, and nothing is higher status than a thriving family of your own. The Amish version of posting exotic vacation pictures on Instagram is showing up to a social function with your new baby. It’s the automatic center of attention for weeks, until a newer baby show up in the community. And the default topic of conversation is always a woman’s children and their growth and development. Young girls grow up dreaming of the day they can join those conversations, and old maids are always outsiders in a certain sense, pitied by everyone else for their misfortune.
Being an old maid means being poor, low status, pitied by other women, and destined to live with your parents until they pass, with your only bitter-sweet consolation being the role of aunt to your dozens of nieces and nephews and maid to your sisters and sisters-in-law through their many pregnancies. Getting married means access to a man’s income, a nice new house just the way you want it, a farm, and an automatic status boost as a mother and eventually grandmother who always has lots to contribute to the conversation at social events.
As you can imagine, the incentives strongly favor marriage from both directions. Men benefit through improved lifestyle, status, and access to sex. Women benefit through improved lifestyle, economic opportunity, and status in the social hierarchy.
Given that the selection pool for potential partners is limited, mostly to the local Amish community, or occasionally another Amish community if there’s some interaction through family ties or social events, assortative mating is the norm. Young people can be choosy, sure. But they already know most of the people in their potential mating pool, and have probably known those people for most of their lives. They have a pretty good idea how desirable they are to potential partners, and the girls especially have to think long and hard about turning down a suitor. Men are always the initiators of a relationship, and the risk of turning down an eligible man and then never getting another offer, ending up as a dreaded old maid, is always lurking in the back of their minds.
Besides that, both men and women have multiple ways to improve their spouse’s life. Women are much more than just sexual objects. Their domestic role actually raises their husband’s standard of living significantly, in a way he can’t access as a single man. And men are all valuable to women, both for resources and for status as a wife and mother. Even a very average husband or wife is a massive lifestyle boost over remaining single.
By now it should be pretty clear why marriage is almost universal among the Amish, and marriage at what most would consider a young age (19-23) is more common than not. And I haven’t even mentioned any religious teaching, because frankly I don’t think that’s a major force on an individual level. The religious beliefs shape the social and material landscape, and that landscape provides the practical incentives that cause people to make the choices they do. The fact that an Amish interpretation of the Bible encourages marriage and children is one layer removed from the reasons individual 20-year-old Amish men and women choose to get married.
I pointed out earlier that getting married and having a high birthrate, or even getting married young and having a high birthrate, are not exactly the same thing. Plenty of married couples today have one, two, or even no children, even if they got married young enough to have ten if they chose to do so. So why are the Amish different?
There’s the too-obvious answer: they don’t allow the use of contraceptives. Occam’s razor and all, but it deserves a bit more explanation. After all, the Catholic Church doesn’t allow the use of contraceptives either, and look how well that’s working out for them. Of course the enforcement mechanism doesn’t have the teeth among Catholics that it has among the Amish, but that’s not the whole story. If they were motivated enough, there’d be a way to space the children out more, maybe end up without quite so many, without anyone knowing. That doesn’t happen, because the contraceptive ban is a dead letter when couples want to have as many children as possible, which the Amish typically do.
Again, I’ll go back to incentives. What are the incentives to have children specifically, as many as possible, and not just get married and “plan for a family one day”?
For one, status. For both men and women, a large family is a marker of high status. Parents are respected and honored for doing a good job of raising well-adjusted children.
Children are also less of a financial burden for the Amish. Their children are raised well, but not in a financially intensive way that’s become expected today. They don’t have to buy a new car or SUV to fit the family, they don’t buy every child a boatload of expensive electronic gadgets every birthday and Christmas, they don’t have to pay for frequent vacations or college tuition, and they don’t have to eat out or pay for takeout or pay for childcare or a house cleaner since the wife is handling all those domestic roles herself. And the Amish don’t practice helicopter parenting, so children are much more free to play and amuse themselves without constant supervision from their parents. They don’t have to be driven to 17 different weekly structured activities. They have a farm to play on and shelves full of books to read and some toys to play with if the weather is bad, and that’s about it. And of course as the family grows, the older siblings do a large percentage of the housework and help with the younger children.
The older teenagers that are working outside the home typically give their earnings to their parents, but this basically offsets the cost of raising them, so it isn’t really an incentive to have larger families, just the removal of a disincentive.
The strongest real incentive, other than increased status and cultural inertia, that I observe for large families is that the children are the parents’ retirement plan. The Amish don’t work at jobs that offer pensions or benefits. They are exempt from paying into, but also ineligible to receive, Social Security benefits. The Social Security exemption was granted on the basis that the Amish don’t need government payments to support them in old age, because the family and community will do that. And they do.
How does this work out in practice? First, the Amish don’t practice “retirement” the way most people think of it. They teach that work is honorable and every able-bodied man should work to support his family and to help those in need. So as long as a man is physically able to work, he’ll be employed and supporting himself and his wife. And Amish women move directly from the role of mother to the role of grandmother. It’s not at all uncommon, in fact, for a woman’s first grandchild to be born before her last child is born. So plenty of Amish children are an aunt or uncle at birth, and have a niece or nephew older than they are. Grandmothers are extremely involved in helping their daughters and daughters-in-law with childcare, so they don’t often have a big stretch of free time after their children grow up and move out. And besides that, there are still the significant household responsibilities to attend to.
As a couple gets older and perhaps less able to handle everything on their own, they often move to the home of one of their grown children. Typically not into the home directly, but into what’s called a “dody haus” (grandpa house) which might be a small detached house on the same property, or a separate wing of the larger house, like an in-law suite. Here they’re able to live independently, help care for the grandchildren next door, and still be nearby so their children and grandchildren can give any care they may need in old age. If the couple has an unmarried “old maid” daughter, she’ll typically still be living with them and will be the primary caregiver.
If someone doesn’t have children to care for them, the Amish community will find a way to care for them. Some more distant relative or maybe surviving siblings will step in to help. But the expectation and the rule is that your children and grandchildren will care for you after you’re no longer able to care for yourself. Finding yourself growing old without family is an unfortunate and unpleasant situation, regardless how much the community may try to fill that role. Just as throughout earlier stages of life, social functions and social status revolve around children and family, and anyone without them will be incomplete as a person, something of an inevitable outsider to the joys of life. The best insurance against a lonely and uncomfortable old age is a large family, among which there are certain to be sufficient resources to care for you. Many elderly Amish people die with well over a hundred grandchildren and great-grandchildren, and spend their later years constantly surrounded by children and young people who deeply appreciate and respect them. Being taught and shown that respect toward their own grandparents from a young age is a strong incentive to aspire to the same status one day.
I’m not sure exactly where this fits, but I should point out somewhere that the Amish have an absolutely zero tolerance policy toward divorce. There are no legitimate grounds for divorce whatsoever, and anyone who initiates a divorce will be excommunicated from the church and shunned. If an Amish person’s spouse initiates divorce proceedings, they won’t cooperate with those proceedings in any way. If the divorce happens through the legal system without their consent anyway, they can remain a church member in good standing only by staying celibate as long as their spouse remains alive. The only acceptable second marriage is in the case of the death of a spouse. In those cases, a quick remarriage is the rule among widows and widowers with young children, since raising a family is seen as a job for a married couple, not a single person.
It’s hard to say exactly how this stance against divorce influences marriage and fertility. But it certainly limits exposure to the idea of divorce as a “solution” to marriage difficulties, and incentivizes couples to work things out for their own life satisfaction. And it dramatically reduces the financial risks men face in the modern marriage system, where the potential to lose not only their family, but also a significant portion of their material wealth, raises strong disincentives to marriage. The physical realities of married life versus single life in a more low-tech environment probably discourage divorce, but the added threat of complete social and familial ostracization eliminate it almost entirely.
Conclusion
This article is my attempt to provide some insight into the Amish culture that might help us understand the factors causing their unusually high fertility rate. I’ve titled it as part one, because I plan to follow up with some of my personal opinions on how these insights relate to the broader society. I think a lot of the proposed causes of and solutions to the global demographic collapse are completely incorrect, and my opinion is based heavily on my observation of Amish culture. That will be the focus of part two of this article.
Feel free to comment and post questions. My biggest challenge in writing this article is the fact that I take my familiarity with Amish culture for granted to some degree, so I struggled to choose which points are relevant to understanding the culture for an outsider. I’m sure I skipped over plenty of important details that may leave readers feeling confused, so I’ll do my best to answer any questions you post, and update the article with pertinent information I missed.

2025-05-16 18:40:18Die zwei mächtigsten Krieger sind Geduld und Zeit. \ Leo Tolstoi
Zum Wohle unserer Gesundheit, unserer Leistungsfähigkeit und letztlich unseres Glücks ist es wichtig, die eigene Energie bewusst zu pflegen. Das gilt umso mehr für an gesellschaftlichen Themen interessierte, selbstbewusste und kritisch denkende Menschen. Denn für deren Wahrnehmung und Wohlbefinden waren und sind die rasanten, krisen- und propagandagefüllten letzten Jahre in Absurdistan eine harte Probe.
Nur wer regelmäßig Kraft tankt und Wege findet, mit den Herausforderungen umzugehen, kann eine solche Tortur überstehen, emotionale Erschöpfung vermeiden und trotz allem zufrieden sein. Dazu müssen wir erkunden, was uns Energie gibt und was sie uns raubt. Durch Selbstreflexion und Achtsamkeit finden wir sicher Dinge, die uns erfreuen und inspirieren, und andere, die uns eher stressen und belasten.
Die eigene Energie ist eng mit unserer körperlichen und mentalen Gesundheit verbunden. Methoden zur Förderung der körperlichen Gesundheit sind gut bekannt: eine ausgewogene Ernährung, regelmäßige Bewegung sowie ausreichend Schlaf und Erholung. Bei der nicht minder wichtigen emotionalen Balance wird es schon etwas komplizierter. Stress abzubauen, die eigenen Grenzen zu kennen oder solche zum Schutz zu setzen sowie die Konzentration auf Positives und Sinnvolles wären Ansätze.
Der emotionale ist auch der Bereich, über den «Energie-Räuber» bevorzugt attackieren. Das sind zum Beispiel Dinge wie Überforderung, Perfektionismus oder mangelhafte Kommunikation. Social Media gehören ganz sicher auch dazu. Sie stehlen uns nicht nur Zeit, sondern sind höchst manipulativ und erhöhen laut einer aktuellen Studie das Risiko für psychische Probleme wie Angstzustände und Depressionen.
Geben wir negativen oder gar bösen Menschen keine Macht über uns. Das Dauerfeuer der letzten Jahre mit Krisen, Konflikten und Gefahren sollte man zwar kennen, darf sich aber davon nicht runterziehen lassen. Das Ziel derartiger konzertierter Aktionen ist vor allem, unsere innere Stabilität zu zerstören, denn dann sind wir leichter zu steuern. Aber Geduld: Selbst vermeintliche «Sonnenköniginnen» wie EU-Kommissionspräsidentin von der Leyen fallen, wenn die Zeit reif ist.
Es ist wichtig, dass wir unsere ganz eigenen Bedürfnisse und Werte erkennen. Unsere Energiequellen müssen wir identifizieren und aktiv nutzen. Dazu gehören soziale Kontakte genauso wie zum Beispiel Hobbys und Leidenschaften. Umgeben wir uns mit Sinnhaftigkeit und lassen wir uns nicht die Energie rauben!
Mein Wahlspruch ist schon lange: «Was die Menschen wirklich bewegt, ist die Kultur.» Jetzt im Frühjahr beginnt hier in Andalusien die Zeit der «Ferias», jener traditionellen Volksfeste, die vor Lebensfreude sprudeln. Konzentrieren wir uns auf die schönen Dinge und auf unsere eigenen Talente – soziale Verbundenheit wird helfen, unsere innere Kraft zu stärken und zu bewahren.

2025-05-24 12:11:01Since its creation, Bitcoin has marked a turning point in the digital money revolution—but its evolution didn’t stop at the original concept of decentralized transactions. Over the years, new technological solutions have been developed to expand its capabilities, making it more efficient and versatile. Among these innovations, smart contracts and the Lightning Network stand out, enabling increased functionality and scalability of the network, and ensuring a faster, cheaper, and more accessible system.
Smart contracts on Bitcoin
Smart contracts are programs that automatically execute certain actions when predefined conditions are met. Although the concept is more commonly associated with other networks, Bitcoin also supports smart contracts, especially through upgrades like Taproot.
- Smart contracts on Bitcoin enable functionalities such as:
01 - Conditional payments: Transactions that are only completed if certain rules are met, such as multi-signatures or specific time conditions.
02 - Advanced fund management: Use of multi-signature wallets, where different parties must approve a transaction before it is processed.
03 - Enhanced privacy: With the Taproot upgrade, smart contracts can be more efficient and indistinguishable from regular transactions, improving privacy across the network.
Although smart contracts on Bitcoin are simpler than those on other platforms, this simplicity is a strength—it preserves the network's security and robustness by avoiding complex vulnerabilities.
Lightning Network: scalability and instant transactions
One of the biggest challenges Bitcoin faces is scalability. Since the original network was designed to prioritize security and decentralization, transaction speed can be limited during periods of high demand. To address this issue, the Lightning Network was created—a second-layer solution that enables near-instant transactions with extremely low fees.
The Lightning Network works by creating payment channels between users, allowing them to conduct multiple transactions off-chain and recording only the final balance on the main Bitcoin blockchain or timechain. Key advantages include:
01 - Speed: Transactions are completed in milliseconds, making Bitcoin more suitable for daily payments.
02 - Low fees: Since transactions occur off-chain, fees are minimal, allowing for viable microtransactions.
03 - Network decongestion: By moving many transactions to the Lightning Network, Bitcoin’s main chain becomes more efficient and less congested.
In summary, Bitcoin continues to evolve technologically to meet the demands of a global financial system. Smart contracts increase its functionality, offering greater flexibility and security in transactions. The Lightning Network improves scalability, making Bitcoin faster and more practical for everyday use. With these innovations, Bitcoin remains at the forefront of the financial revolution, proving that despite its initial limitations, it continues to adapt and grow as a truly decentralized and global monetary system.

อลิซต้องการจ่ายเงินให้กับบ๊อบแต่โหนดของบิตคอยน์ในระบบหลายพันโหนดจะตรวจสอบธุรกรรมของเธอ โดยไม่รู้ว่าอลิซหรือบ๊อบเป็นใคร ละเราต้องการรักษาความเป็นส่วนตัวของพวกเขาไว้เช่นนี้ อลิซจำเป็นต้องสื่อสารว่าบ๊อบควรได้รับบิตคอยน์บางส่วนของเธอโดยไม่เชื่อมโยงแง่มุมใด ๆ ของธุรกรรมนั้นกับตัวตนในโลกจริงของบ๊อบ หรือกับการชำระเงินด้วยบิตคอยน์ครั้งอื่น ๆ ที่บ๊อบได้รับ อลิซใช้ต้องทำให้มั่นใจว่ามีเพียแค่บ๊อบเท่านั้นที่สามารถใช้จ่ายบิตคอยน์ที่เขาได้รับต่อไปได้
ในบิตคอยน์ไวท์เปเปอร์ได้อธิบายถึงแผนการที่เรียบง่ายมากสำหรับการบรรลุเป้าหมายเหล่านั้น ดังที่แสดงในรูปด้านล่างนี้
ตัวของผู้รับอย่างบ๊อบเองจะได้รับบิตคอยน์ไปยัง public key ของเขาที่ถูกลงนามโดยผู้จ่ายอย่างอลิซ โดยบิตคอยน์ที่อลิซนำมาจ่ายนั้นก็ได้รับมาจากที่ใครสักคนส่งมาที่ public key ของเธอ และเธอก็ใช้ private key ของเธอในการลงนามเพื่อสร้างลายเซ็นของเธอและโหนดต่าง ๆ ของบิตคอยน์จะทำการตรวจสอบว่าลายเซ็นของอลิซผูกมัดกับเอาต์พุตของฟังก์ชันแฮชซึ่งตัวมันเองผูกมัดกับ public key ของบ๊อบและรายละเอียดธุรกรรมอื่นๆ
ในบทนี้เราจะพิจารณาpublic key private key Digital signatrue และ hash function จากนั้นใช้ทั้งหมดนี้ร่วมกันเพื่ออธิบาย address ที่ใช้โดยซอฟต์แวร์บิตคอยน์สมัยใหม่
Public Key Cryptography (การเข้ารหัสของ public key)
ระบบเข้ารหัสของ public key ถูกคิดค้นขึ้นในทศวรรษ 1970 มาจากรากฐานทางคณิตศาสตร์สำหรับความปลอดภัยของคอมพิวเตอร์และข้อมูลสมัยใหม่
นับตั้งแต่การคิดค้นระบบเข้ารหัส public key ได้มีการค้นพบฟังก์ชันทางคณิตศาสตร์ที่เหมาะสมหลายอย่าง เช่น การยกกำลังของจำนวนเฉพาะและการคูณของเส้นโค้งวงรี โดยฟังก์ชันทางคณิตศาสตร์เหล่านี้สามารถคำนวณได้ง่ายในทิศทางหนึ่ง แต่เป็นไปไม่ได้ที่จะคำนวณในทิศทางตรงกันข้ามโดยใช้คอมพิวเตอร์และอัลกอริทึมที่มีอยู่ในปัจจุบัน จากฟังก์ชันทางคณิตศาสตร์เหล่านี้ การเข้ารหัสลับช่วยให้สามารถสร้างลายเซ็นดิจิทัลที่ไม่สามารถปลอมแปลงได้และบิตคอยน์ได้ใช้การบวกและการคูณของเส้นโค้งวงรีเป็นพื้นฐานสำหรับการเข้ารหัสลับของมัน
ในบิตคอยน์ เราสามารถใช้ระบบเข้ารหัส public key เพื่อสร้างคู่กุญแจที่ควบคุมการเข้าถึงบิตคอยน์ คู่กุญแจประกอบด้วย private key และ public key ที่ได้มาจาก private key public keyใช้สำหรับรับเงิน และ private key ใช้สำหรับลงนามในธุรกรรมเพื่อใช้จ่ายเงิน
ความสัมพันธ์ทางคณิตศาสตร์ระหว่าง public key และ private key ที่ช่วยให้ private key สามารถใช้สร้างลายเซ็นบนข้อความได้ ลายเซ็นเหล่านี้สามารถตรวจสอบความถูกต้องกับ public key ได้โดยไม่เปิดเผย private key
TIP: ในการใช้งานซอฟแวร์กระเป๋าเงินบิตคอยน์บสงอัน จะทำการเก็บ private key และ public key ถูกเก็บไว้ด้วยกันในรูปแบบคู่กุญแจเพื่อความสะดวก แต่อย่างไรก็ตาม public key สามารถคำนวณได้จาก private key ดังนั้นการเก็บเพียง private key เท่านั้นก็เป็นไปได้เช่นกัน
bitcoin wallet มักจะทำการรวบรวมคู่กุญแต่ละคู่ ซึ่งจะประกอบไปด้วย private key และ public key โดย private key จะเป็นตัวเลขที่ถูกสุ่มเลือกขึ้นมา และเราขะใช้เส้นโค้งวงรี ซึ่งเป็นฟังก์ชันการเข้ารหัสทางเดียว เพื่อสร้าง public key ขึ้นมา
ทำไมจึงใช้การเข้ารหัสแบบอสมมาตร
ทำไมการเข้ารหัสแบบอสมมาตรจึงถูกใช้บิตคอยน์? มันไม่ได้ถูกใช้เพื่อ "เข้ารหัส" (ทำให้เป็นความลับ) ธุรกรรม แต่คุณสมบัติที่มีประโยชน์ของการเข้ารหัสแบบอสมมาตรคือความสามารถในการสร้าง ลายเซ็นดิจิทัล private key สามารถนำไปใช้กับธุรกรรมเพื่อสร้างลายเซ็นเชิงตัวเลข ลายเซ็นนี้สามารถสร้างได้เฉพาะโดยผู้ที่มีความเกี่ยวข้องกับ private key เท่านั้น แต่อย่างไรก็ตาม ทุกคนที่สามารถเข้าถึง public key และธุรกรรมสามารถใช้สิ่งเหล่านี้เพื่อ ตรวจสอบ ลายเซ็นได้ คุณสมบัติที่มีประโยชน์นี้ของการเข้ารหัสแบบอสมมาตรทำให้ทุกคนสามารถตรวจสอบลายเซ็นทุกรายการในทุกธุรกรรมได้ ในขณะที่มั่นใจว่าเฉพาะเจ้าของ private key เท่านั้นที่สามารถสร้างลายเซ็นที่ถูกต้องได้
Private keys
private key เป็นเพียงตัวเลขที่ถูกสุ่มขึ้น และการควบคุม private key ก็เป็นรากฐานสำคัญที่ทำให้เจ้าชองกุญแจดอกนี้สามารถควบคุมบิตคอยน์ทั้งหมดที่มีความเกี่ยวข้องกับ public key ที่คู่กัน private key นั้นใช้ในการสร้างลายเซ็นดิจิทัลที่ใช้ในการเคลื่อนย้ายบิตคอยน์ เราจำเป็นต้องเก็บ private key ให้เป็นความลับตลอดเวลา เพราะการเปิดเผยมันให้กับบุคคลอื่นนั้นก็เปรียบเสมือนกับการนำอำนาจในการควบคุมบิตคอยน์ไปให้แก่เขา นอกจากนี้ private key ยังจำเป็นต้องได้รับการสำรองข้อมูลและป้องกันจากการสูญหายโดยไม่ตั้งใจ เพราะหากเราได้ทำมันสูญหายไป จะไม่สามารถกู้คืนได้ และบิตคอยน์เหล่านั้นจะถูกปกป้องโดยกุญแจที่หายไปนั้นตลอดกาลเช่นกัน
TIP: private key ของบิตคอยน์นั้นเป็นเพียงแค่ตัวเลข คุณสามารถสร้างมันได้โดยใช้เพียงเหรียญ ดินสอ และกระดาษ โดยการโยนเหรียญเพียง 256 ครั้งจะทำให้คุณได้เลขฐานสองที่สามารถใช้เป็น private key ของบิตคอยน์ จากนั้นคุณสามารถใช้มันในการคำนวณหา public key แต่อย่างไรก็ตาม โปรดระมัดระวังเกี่ยวกับการเลือใช้วิธีการสุ่มที่ไม่สมบูรณ์ เพราะนั่นอาจลดความปลอดภัยของ private key และบิตคอยน์ที่มัมปกป้องอยู่อย่างมีนัยสำคัญ
ขั้นตอนแรกและสำคัญที่สุดในการสร้างกุญแจคือการหาแหล่งที่มาของความสุ่มที่ปลอดภัย (ซึ่งเรียกว่า เอนโทรปี) การสร้างกุญแจของบิตคอยน์นั้นเกือบเหมือนกับ "เลือกตัวเลขระหว่าง 1 และ 2^256" ซึ่งวิธีที่แน่นอนที่คุณใช้ในการเลือกตัวเลขนั้นไม่สำคัญตราบใดที่มันไม่สามารถคาดเดาหรือทำซ้ำได้ โดยปกติแล้วซอฟต์แวร์ของบิตคอยน์มักจะใช้ตัวสร้างตัวเลขสุ่มที่มีความปลอดภัยทางการเข้ารหัสเพื่อสร้างเอนโทรปี 256 บิต
สิ่งที่สำคัญในเรื่องนี้คือ private key สามารถเป็นตัวเลขใดๆ ระหว่าง 0 และ n - 1 (รวมทั้งสองค่า) โดยที่ n เป็นค่าคงที่ (n = 1.1578 × 10^77 ซึ่งน้อยกว่า 2^256 เล็กน้อย) ซึ่งกำหนดอยู่ใน elliptic curve ที่ใช้ใน Bitcoin ในการสร้างกุญแจดังกล่าว เราสุ่มเลือกเลขขนาด 256 บิตและตรวจสอบว่ามันน้อยกว่า n ในแง่ของการเขียนโปรแกรม โดยปกติแล้วสิ่งนี้ทำได้โดยการป้อนสตริงของบิตสุ่มที่ใหญ่กว่า ซึ่งรวบรวมจากแหล่งที่มาของความสุ่มที่มีความปลอดภัยทางการเข้ารหัส เข้าไปในอัลกอริทึมแฮช SHA256 ซึ่งจะสร้างค่าขนาด 256 บิตที่สามารถตีความเป็นตัวเลขได้อย่างสะดวก หากผลลัพธ์น้อยกว่า n เราจะได้กุญแจส่วนตัวที่เหมาะสม มิฉะนั้น เราก็เพียงแค่ลองอีกครั้งด้วยตัวเลขสุ่มอื่น
คำเตือน: อย่าเขียนโค้ดของคุณเองเพื่อสร้างตัวเลขสุ่ม หรือใช้ตัวสร้างตัวเลขสุ่ม "แบบง่าย" ที่มีให้ในภาษาโปรแกรมของคุณ ใช้ตัวสร้างตัวเลขสุ่มเทียมที่มีความปลอดภัยทางการเข้ารหัส (CSPRNG) จากแหล่งที่มีเอนโทรปีเพียงพอ ศึกษาเอกสารของไลบรารีตัวสร้างตัวเลขสุ่มที่คุณเลือกเพื่อให้มั่นใจว่ามีความปลอดภัยทางการเข้ารหัส การใช้งาน CSPRNG ที่ถูกต้องมีความสำคัญอย่างยิ่งต่อความปลอดภัยของกุญแจ
ต่อไปนี้คือกุญแจส่วนตัว (k) ที่สร้างขึ้นแบบสุ่มซึ่งแสดงในรูปแบบเลขฐานสิบหก (256 บิตแสดงเป็น 64 หลักเลขฐานสิบหก โดยแต่ละหลักคือ 4 บิต):
1E99423A4ED27608A15A2616A2B0E9E52CED330AC530EDCC32C8FFC6A526AEDD
TIP: จำนวนที่เป็นไปได้ของ private key ทั้งหมดนั้นมีอยู่ 2^256 เป็นตัวเลขที่ใหญ่มากจนยากจะจินตนาการได้ มันมีค่าประมาณ 10^77 (เลข 1 ตามด้วยเลข 0 อีก 77 ตัว) ในระบบเลขฐานสิบ เพื่อให้เข้าใจง่ายขึ้น ลองเปรียบเทียบกับจักรวาลที่เรามองเห็นได้ซึ่งนักวิทยาศาสตร์ประมาณการว่ามีอะตอมทั้งหมดประมาณ 10^80 อะตอม นั่นหมายความว่าช่วงค่าของกุญแจส่วนตัว Bitcoin มีขนาดใกล้เคียงกับจำนวนอะตอมทั้งหมดในจักรวาลที่เรามองเห็นได้
การอธิบายเกี่ยวกับวิทยาการเข้ารหัสแบบเส้นโค้งวงรี (Elliptic Curve Cryptography)
วิทยาการเข้ารหัสแบบเส้นโค้งวงรี (ECC) เป็นประเภทหนึ่งของการเข้ารหัสแบบอสมมาตรหรือ public key ซึ่งอาศัยหลักการของปัญหาลอการิทึมแบบไม่ต่อเนื่อง โดยแสดงออกผ่านการบวกและการคูณบนจุดต่างๆ ของเส้นโค้งวงรี
บิตคอยน์ใช้เส้นโค้งวงรีเฉพาะและชุดค่าคงที่ทางคณิตศาสตร์ ตามที่กำหนดไว้ในมาตรฐานที่เรียกว่า secp256k1 ซึ่งกำหนดโดยสถาบันมาตรฐานและเทคโนโลยีแห่งชาติ (NIST) เส้นโค้ง secp256k1 ถูกกำหนดโดยฟังก์ชันต่อไปนี้ ซึ่งสร้างเส้นโค้งวงรี: y² = (x³ + 7) บนฟิลด์จำกัด (F_p) หรือ y² mod p = (x³ + 7) mod p
โดยที่ mod p (มอดูโลจำนวนเฉพาะ p) แสดงว่าเส้นโค้งนี้อยู่บนฟิลด์จำกัดของอันดับจำนวนเฉพาะ p ซึ่งเขียนได้เป็น F_p โดย p = 2^256 – 2^32 – 2^9 – 2^8 – 2^7 – 2^6 – 2^4 – 1 ซึ่งเป็นจำนวนเฉพาะที่มีค่ามหาศาล
บิตคอยน์ใช้เส้นโค้งวงรีที่ถูกนิยามบนฟิลด์จำกัดของอันดับจำนวนเฉพาะแทนที่จะอยู่บนจำนวนจริง ทำให้มันมีลักษณะเหมือนรูปแบบของจุดที่กระจัดกระจายในสองมิติ ซึ่งทำให้ยากต่อการจินตนาการภาพ อย่างไรก็ตาม คณิตศาสตร์ที่ใช้นั้นเหมือนกับเส้นโค้งวงรีบนจำนวนจริง
ตัวอย่างเช่น การเข้ารหัสลับด้วยเส้นโค้งวงรี: การแสดงภาพเส้นโค้งวงรีบน F(p) โดยที่ p=17 แสดงเส้นโค้งวงรีเดียวกันบนฟิลด์จำกัดของอันดับจำนวนเฉพาะ 17 ที่มีขนาดเล็กกว่ามาก ซึ่งแสดงรูปแบบของจุดบนตาราง
เส้นโค้งวงรี secp256k1 ที่ใช้ในบิตคอยน์สามารถนึกถึงได้ว่าเป็นรูปแบบของจุดที่ซับซ้อนมากกว่าบนตารางที่มีขนาดใหญ่มหาศาลจนยากจะเข้าใจได้
ตัวอย่างเช่น จุด P ที่มีพิกัด (x, y) ต่อไปนี้เป็นจุดที่อยู่บนเส้นโค้ง secp256k1:
P = (55066263022277343669578718895168534326250603453777594175500187360389116729240, 32670510020758816978083085130507043184471273380659243275938904335757337482424)
เราสามารถใช้ Python เพื่อยืนยันว่าจุดนี้อยู่บนเส้นโค้งวงรีได้ตามตัวอย่างนี้: ตัวอย่างที่ 1: การใช้ Python เพื่อยืนยันว่าจุดนี้อยู่บนเส้นโค้งวงรี ``` Python 3.10.6 (main, Nov 14 2022, 16:10:14) [GCC 11.3.0] on linux Type "help", "copyright", "credits" or "license" for more information.p = 115792089237316195423570985008687907853269984665640564039457584007908834671663 x = 55066263022277343669578718895168534326250603453777594175500187360389116729240 y = 32670510020758816978083085130507043184471273380659243275938904335757337482424 (x ** 3 + 7 - y**2) % p 0 ``` ผลลัพธ์เป็น 0 ซึ่งแสดงว่าจุดนี้อยู่บนเส้นโค้งวงรีจริง เพราะเมื่อแทนค่า x และ y ลงในสมการ y² = (x³ + 7) mod p แล้ว ทั้งสองด้านของสมการมีค่าเท่ากัน
ในคณิตศาสตร์ของเส้นโค้งวงรี มีจุดที่เรียกว่า "จุดที่อนันต์" (point at infinity) ซึ่งมีบทบาทคล้ายกับศูนย์ในการบวก บนคอมพิวเตอร์ บางครั้งจุดนี้แทนด้วย x = y = 0 (ซึ่งไม่เป็นไปตามสมการเส้นโค้งวงรี แต่เป็นกรณีพิเศษที่สามารถตรวจสอบได้ง่าย)
มีตัวดำเนินการ + ที่เรียกว่า "การบวก" ซึ่งมีคุณสมบัติคล้ายกับการบวกแบบดั้งเดิมของจำนวนจริงที่เด็กๆ เรียนในโรงเรียน เมื่อมีจุดสองจุด P1 และ P2 บนเส้นโค้งวงรี จะมีจุดที่สาม P3 = P1 + P2 ซึ่งอยู่บนเส้นโค้งวงรีเช่นกัน
ในเชิงเรขาคณิต จุดที่สาม P3 นี้คำนวณได้โดยการลากเส้นระหว่าง P1 และ P2 เส้นนี้จะตัดกับเส้นโค้งวงรีที่จุดเพิ่มเติมอีกหนึ่งจุดพอดี เรียกจุดนี้ว่า P3' = (x, y) จากนั้นให้สะท้อนกับแกน x เพื่อได้ P3 = (x, -y)
มีกรณีพิเศษบางกรณีที่อธิบายความจำเป็นของ "จุดที่อนันต์":
- ถ้า P1 และ P2 เป็นจุดเดียวกัน เส้น "ระหว่าง" P1 และ P2 ควรขยายเป็นเส้นสัมผัสกับเส้นโค้ง ณ จุด P1 นี้ เส้นสัมผัสนี้จะตัดกับเส้นโค้งที่จุดใหม่อีกหนึ่งจุดพอดี คุณสามารถใช้เทคนิคจากแคลคูลัสเพื่อหาความชันของเส้นสัมผัส เทคนิคเหล่านี้ใช้ได้อย่างน่าแปลกใจ แม้ว่าเราจะจำกัดความสนใจไว้ที่จุดบนเส้นโค้งที่มีพิกัดเป็นจำนวนเต็มเท่านั้น!
- ในบางกรณี (เช่น ถ้า P1 และ P2 มีค่า x เดียวกันแต่ค่า y ต่างกัน) เส้นสัมผัสจะตั้งฉากพอดี ซึ่งในกรณีนี้ P3 = "จุดที่อนันต์"
- ถ้า P1 เป็น "จุดที่อนันต์" แล้ว P1 + P2 = P2 ในทำนองเดียวกัน ถ้า P2 เป็นจุดที่อนันต์ แล้ว P1 + P2 = P1 นี่แสดงให้เห็นว่าจุดที่อนันต์มีบทบาทเป็นศูนย์
การบวกนี้มีคุณสมบัติเชิงสมาคม (associative) ซึ่งหมายความว่า (A + B) + C = A + (B + C) นั่นหมายความว่าเราสามารถเขียน A + B + C โดยไม่ต้องมีวงเล็บและไม่มีความกำกวม
เมื่อเรานิยามการบวกแล้ว เราสามารถนิยามการคูณในแบบมาตรฐานที่ต่อยอดจากการบวก สำหรับจุด P บนเส้นโค้งวงรี ถ้า k เป็นจำนวนเต็มบวก แล้ว kP = P + P + P + … + P (k ครั้ง) โปรดทราบว่า k บางครั้งถูกเรียกว่า "เลขชี้กำลัง"
Public Keys
ในระบบคริปโตกราฟีแบบเส้นโค้งวงรี (Elliptic Curve Cryptography) public key ถูกคำนวณจาก private key โดยใช้การคูณเส้นโค้งวงรี ซึ่งเป็นกระบวนการที่ไม่สามารถย้อนกลับได้:
K = k × G
โดยที่:
- k คือ private key
- G คือจุดคงที่ที่เรียกว่า จุดกำเนิด (generator point)
- K คือ public key
การดำเนินการย้อนกลับ ที่เรียกว่า "การหาลอการิทึมแบบไม่ต่อเนื่อง" (finding the discrete logarithm) - คือการคำนวณหา k เมื่อรู้ค่า K - เป็นสิ่งที่ยากมากเทียบเท่ากับการลองค่า k ทุกค่าที่เป็นไปได้ (วิธีการแบบ brute-force)
ความยากของการย้อนกลับนี้คือหลักการความปลอดภัยหลักของระบบ ECC ที่ใช้ในบิตคอยน์ ซึ่งทำให้สามารถเผยแพร่ public key ได้อย่างปลอดภัย โดยที่ไม่ต้องกังวลว่าจะมีใครสามารถคำนวณย้อนกลับเพื่อหา private key ได้
TIP:การคูณเส้นโค้งวงรีเป็นฟังก์ชันประเภทที่นักเข้ารหัสลับเรียกว่า “ trap door function ”:
- เป็นสิ่งที่ทำได้ง่ายในทิศทางหนึ่ง
- แต่เป็นไปไม่ได้ที่จะทำในทิศทางตรงกันข้าม
คนที่มี private key สามารถสร้าง public key ได้อย่างง่ายดาย และสามารถแบ่งปันกับโลกได้โดยรู้ว่าไม่มีใครสามารถย้อนกลับฟังก์ชันและคำนวณ private key จาก public key ได้ กลวิธีทางคณิตศาสตร์นี้กลายเป็นพื้นฐานสำหรับลายเซ็นดิจิทัลที่ปลอมแปลงไม่ได้และมีความปลอดภัย ซึ่งใช้พิสูจน์การควบคุมเงินบิตคอยน์
เริ่มต้นด้วยการใช้ private key ในรูปแบบของตัวเลขสุ่ม เราคูณมันด้วยจุดที่กำหนดไว้ล่วงหน้าบนเส้นโค้งที่เรียกว่า จุดกำเนิด (generator point) เพื่อสร้างจุดอื่นที่อยู่บนเส้นโค้งเดียวกัน ซึ่งคำตอบจะเป็น public key ที่สอดคล้องกัน จุดกำเนิดถูกกำหนดไว้เป็นส่วนหนึ่งของมาตรฐาน secp256k1 และเป็นค่าเดียวกันสำหรับกุญแจทั้งหมดในระบบบิตคอยน์
เนื่องจากจุดกำเนิด G เป็นค่าเดียวกันสำหรับผู้ใช้บิตคอยน์ทุกคน private key (k) ที่คูณกับ G จะได้ public key (K) เดียวกันเสมอ ความสัมพันธ์ระหว่าง k และ K เป็นแบบตายตัวแต่สามารถคำนวณได้ในทิศทางเดียวเท่านั้น คือจาก k ไปยัง K นี่คือเหตุผลที่ public key ของบิตคอยน์ (K) สามารถแบ่งปันกับทุกคนได้โดยไม่เปิดเผย private key (k) ของผู้ใช้
TIP: private key สามารถแปลงเป็น public key ได้ แต่ public key ไม่สามารถแปลงกลับเป็น private key ได้ เพราะคณิตศาสตร์ที่ใช้ทำงานได้เพียงทิศทางเดียวเท่านั้น
เมื่อนำการคูณเส้นโค้งวงรีมาใช้งาน เราจะนำ private key (k) ที่สร้างขึ้นก่อนหน้านี้มาคูณกับจุดกำเนิด G เพื่อหา public key (K):
K = 1E99423A4ED27608A15A2616A2B0E9E52CED330AC530EDCC32C8FFC6A526AEDD × G
public key (K) จะถูกกำหนดเป็นจุด K = (x, y) โดยที่:x = F028892BAD7ED57D2FB57BF33081D5CFCF6F9ED3D3D7F159C2E2FFF579DC341A y = 07CF33DA18BD734C600B96A72BBC4749D5141C90EC8AC328AE52DDFE2E505BDB
เพื่อจะให้เห็นภาพของการคูณจุดด้วยจำนวนเต็มมากขึ้น เราจะใช้เส้นโค้งวงรีที่ง่ายกว่าบนจำนวนจริง (โดยหลักการทางคณิตศาสตร์ยังคงเหมือนกัน) เป้าหมายของเราคือการหาผลคูณ kG ของจุดกำเนิด G ซึ่งเทียบเท่ากับการบวก G เข้ากับตัวเอง k ครั้งติดต่อกันในเส้นโค้งวงรี การบวกจุดเข้ากับตัวเองเทียบเท่ากับการลากเส้นสัมผัสที่จุดนั้นและหาว่าเส้นนั้นตัดกับเส้นโค้งอีกครั้งที่จุดใด จากนั้นจึงสะท้อนจุดนั้นบนแกน x
การเข้ารหัสลับด้วยเส้นโค้งวงรี: การแสดงภาพการคูณจุด G ด้วยจำนวนเต็ม k บนเส้นโค้งวงรี แสดงกระบวนการในการหา G, 2G, 4G เป็นการดำเนินการทางเรขาคณิตบนเส้นโค้งได้ดังนี้
TIP: ในซอฟแวร์ของบิตคอยน์ส่วนใหญ่ใช้ไลบรารีเข้ารหัสลับ libsecp256k1 เพื่อทำการคำนวณทางคณิตศาสตร์เส้นโค้งวงรี
Output and Input Scripts
แม้ว่าภาพประกอบจาก Bitcoin whitepaper ที่แสดงเรื่อง "Transaction chain" จะแสดงให้เห็นว่ามีการใช้ public key และ digital signature โดยตรง แต่ในความเป็นจริงบิตคอยน์เวอร์ชันแรกนั้นมีการส่งการชำระเงินไปยังฟิลด์ที่เรียกว่า output script และมีการใช้จ่ายบิตคอยน์เหล่านั้นโดยได้รับอนุญาตจากฟิลด์ที่เรียกว่า input script ฟิลด์เหล่านี้อนุญาตให้มีการดำเนินการเพิ่มเติมนอกเหนือจาก (หรือแทนที่) การตรวจสอบว่าลายเซ็นสอดคล้องกับ public key หรือไม่ ตัวอย่างเช่น output script สามารถมี public key สองดอกและต้องการลายเซ็นสองลายเซ็นที่สอดคล้องกันในฟิลด์ input script ที่ใช้จ่าย
ในภายหลัง ในหัวข้อ [tx_script] เราจะได้เรียนรู้เกี่ยวกับสคริปต์อย่างละเอียด สำหรับตอนนี้ สิ่งที่เราต้องเข้าใจคือ บิตคอยน์จะถูกรับเข้า output script ที่ทำหน้าที่เหมือน public key และการใช้จ่ายบิตคอยน์จะได้รับอนุญาตโดย input script ที่ทำหน้าที่เหมือนลายเซ็น
IP Addresses: The Original Address for Bitcoin (P2PK)
เราได้เห็นแล้วว่าอลิซสามารถจ่ายเงินให้บ็อบโดยการมอบบิตคอยน์บางส่วนของเธอให้กับกุญแจสาธารณะของบ็อบ แต่อลิซจะได้กุญแจสาธารณะของบ็อบมาได้อย่างไร? บ็อบอาจจะให้สำเนากุญแจแก่เธอ แต่ลองดูกุญแจสาธารณะที่เราใช้งานในตัวอย่างที่ผ่านมาอีกครั้ง:
x = F028892BAD7ED57D2FB57BF33081D5CFCF6F9ED3D3D7F159C2E2FFF579DC341A y = 07CF33DA18BD734C600B96A72BBC4749D5141C90EC8AC328AE52DDFE2E505BDB
TIP จากหลาม: :สังเกตได้ว่า public key มีความยาวมาก ลองจินตนาการว่าบ็อบพยายามอ่านกุญแจนี้ให้อลิซฟังทางโทรศัพท์ คงจะยากมากที่จะอ่านและบันทึกโดยไม่มีข้อผิดพลาด
แทนที่จะป้อนกุญแจสาธารณะโดยตรง เวอร์ชันแรกของซอฟต์แวร์บิตคอยน์อนุญาตให้ผู้จ่ายเงินป้อนที่อยู่ IP ของผู้รับได้ ตามที่แสดงในหน้าจอการส่งเงินรุ่นแรกของบิตคอยน์ผ่าน The Internet Archive
คุณสมบัตินี้ถูกลบออกในภายหลัง เนื่องจากมีปัญหามากมายในการใช้ที่อยู่ IP แต่คำอธิบายสั้นๆ จะช่วยให้เราเข้าใจได้ดีขึ้นว่าทำไมคุณสมบัติบางอย่างอาจถูกเพิ่มเข้าไปในโปรโตคอลบิตคอยน์
เมื่ออลิซป้อนที่อยู่ IP ของบ็อบในบิตคอยน์เวอร์ชัน 0.1 Full node ของเธอจะทำการเชื่อมต่อกับ full node ของเขาและได้รับ public key ใหม่จากกระเป๋าสตางค์ของบ็อบที่โหนดของเขาไม่เคยให้กับใครมาก่อน การที่เป็น public key ใหม่นี้มีความสำคัญเพื่อให้แน่ใจว่าธุรกรรมต่าง ๆ ที่จ่ายให้บ็อบจะไม่สามารถถูกเชื่อมโยงเข้าด้วยกันโดยคนที่กำลังดูบล็อกเชนและสังเกตเห็นว่าธุรกรรมทั้งหมดจ่ายไปยัง public key เดียวกัน
เมื่อใช้ public key จากโหนดของอลิซซึ่งได้รับมาจากโหนดของบ็อบ กระเป๋าสตางค์ของอลิซจะสร้างเอาต์พุตธุรกรรมที่จ่ายให้กับสคริปต์เอาต์พุตดังนี้
<Bob's public key> OP_CHECKSIG
ต่อมาบ็อบจะสามารถใช้จ่ายเอาต์พุตนั้นด้วยสคริปต์อินพุตที่ประกอบด้วยลายเซ็นของเขาเท่านั้น:<Bob's signature>
เพื่อให้เข้าใจว่าสคริปต์อินพุตและเอาต์พุตกำลังทำอะไร คุณสามารถรวมพวกมันเข้าด้วยกัน (สคริปต์อินพุตก่อน) แล้วสังเกตว่าข้อมูลแต่ละชิ้น (แสดงในเครื่องหมาย < >) จะถูกวางไว้ที่ด้านบนสุดของรายการที่เรียกว่าสแตก (stack) เมื่อพบรหัสคำสั่ง (opcode) มันจะใช้รายการจากสแตก โดยเริ่มจากรายการบนสุด มาดูว่ามันทำงานอย่างไรโดยเริ่มจากสคริปต์ที่รวมกัน:<Bob's signature> <Bob's public key> OP_CHECKSIG
สำหรับสคริปต์นี้ ลายเซ็นของบ็อบจะถูกนำไปไว้บนสแตก จากนั้น public key ของบ็อบจะถูกวางไว้ด้านบนของลายเซ็น และบนสุดจะเป็นคำสั่ง OP_CHECKSIG ที่จะใช้องค์ประกอบสองอย่าง เริ่มจาก public key ตามด้วยลายเซ็น โดยลบพวกมันออกจากสแตก มันจะตรวจสอบว่าลายเซ็นตรงกับ public key และยืนยันฟิลด์ต่าง ๆ ในธุรกรรม ถ้าลายเซ็นถูกต้อง OP_CHECKSIG จะแทนที่ตัวเองบนสแตกด้วยค่า 1 ถ้าลายเซ็นไม่ถูกต้อง มันจะแทนที่ตัวเองด้วย 0 ถ้ามีรายการที่ไม่ใช่ศูนย์อยู่บนสุดของสแตกเมื่อสิ้นสุดการประเมิน สคริปต์ก็จะผ่าน ถ้าสคริปต์ทั้งหมดในธุรกรรมผ่าน และรายละเอียดอื่น ๆ ทั้งหมดเกี่ยวกับธุรกรรมนั้นต้องถูกต้องจึงจะถือว่าธุรกรรมนั้นถูกต้อง
โดยสรุป สคริปต์ข้างต้นใช้ public key และลายเซ็นเดียวกันกับที่อธิบายใน whitepaper แต่เพิ่มความซับซ้อนของฟิลด์สคริปต์สองฟิลด์และรหัสคำสั่งหนึ่งตัว ซึ่งเราจะเริ่มเห็นประโยชน์เมื่อเรามองที่ส่วนต่อไป
TIP:จากหลาม agian: เอาต์พุตประเภทนี้เป็นที่รู้จักในปัจจุบันว่า P2PK ซึ่งมันไม่เคยถูกใช้อย่างแพร่หลายสำหรับการชำระเงิน และไม่มีโปรแกรมที่ใช้กันอย่างแพร่หลายที่รองรับการชำระเงินผ่านที่อยู่ IP เป็นเวลาเกือบทศวรรษแล้ว
Legacy addresses for P2PKH
แน่นอนว่าการป้อนที่อยู่ IP ของคนที่คุณต้องการจ่ายเงินให้นั้นมีข้อดีหลายประการ แต่ก็มีข้อเสียหลายประการเช่นกัน หนึ่งในข้อเสียที่สำคัญคือผู้รับจำเป็นต้องให้กระเป๋าสตางค์ของพวกเขาออนไลน์ที่ที่อยู่ IP ของพวกเขา และต้องสามารถเข้าถึงได้จากโลกภายนอก
ซึ่งสำหรับคนจำนวนมากนั่นไม่ใช่ตัวเลือกที่เป็นไปได้เพราะหากพวกเขา:
- ปิดคอมพิวเตอร์ในเวลากลางคืน
- แล็ปท็อปของพวกเขาเข้าสู่โหมดสลีป
- อยู่หลังไฟร์วอลล์
- หรือกำลังใช้การแปลงที่อยู่เครือข่าย (NAT)
ปัญหานี้นำเรากลับมาสู่ความท้าทายเดิมที่ผู้รับเงินอย่างบ็อบต้องให้ public key ที่มีความยาวมากแก่ผู้จ่ายเงินอย่างอลิซ public key ของบิตคอยน์ที่สั้นที่สุดที่นักพัฒนาบิตคอยน์รุ่นแรกรู้จักมีขนาด 65 ไบต์ เทียบเท่ากับ 130 ตัวอักษรเมื่อเขียนในรูปแบบเลขฐานสิบหก (เฮกซาเดซิมอล) แต่อย่างไรก็ตาม บิตคอยน์มีโครงสร้างข้อมูลหลายอย่างที่มีขนาดใหญ่กว่า 65 ไบต์มาก ซึ่งจำเป็นต้องถูกอ้างอิงอย่างปลอดภัยในส่วนอื่น ๆ ของบิตคอยน์โดยใช้ข้อมูลขนาดเล็กที่สุดเท่าที่จะปลอดภัยได้
โดยบิตคอยน์แก้ปัญหานี้ด้วย ฟังก์ชันแฮช (hash function) ซึ่งเป็นฟังก์ชันที่รับข้อมูลที่อาจมีขนาดใหญ่ นำมาแฮช และให้ผลลัพธ์เป็นข้อมูลขนาดคงที่ ฟังก์ชันแฮชจะผลิตผลลัพธ์เดียวกันเสมอเมื่อได้รับข้อมูลนำเข้าแบบเดียวกัน และฟังก์ชันที่ปลอดภัยจะทำให้เป็นไปไม่ได้ในทางปฏิบัติสำหรับผู้ที่ต้องการเลือกข้อมูลนำเข้าอื่นที่ให้ผลลัพธ์เหมือนกันได้ นั่นทำให้ผลลัพธ์เป็น คำมั่นสัญญา (commitment) ต่อข้อมูลนำเข้า เป็นสัญญาว่าในทางปฏิบัติ มีเพียงข้อมูลนำเข้า x เท่านั้นที่จะให้ผลลัพธ์ X
สมมติว่าผมต้องการถามคำถามคุณและให้คำตอบของผมในรูปแบบที่คุณไม่สามารถอ่านได้ทันที สมมติว่าคำถามคือ "ในปีไหนที่ซาโตชิ นาคาโมโตะเริ่มทำงานบนบิทคอยน์?" ผมจะให้การยืนยันคำตอบของผมในรูปแบบของผลลัพธ์จากฟังก์ชันแฮช SHA256 ซึ่งเป็นฟังก์ชันที่ใช้บ่อยที่สุดในบิทคอยน์:
94d7a772612c8f2f2ec609d41f5bd3d04a5aa1dfe3582f04af517d396a302e4e
ต่อมา หลังจากคุณบอกคำตอบที่คุณเดาสำหรับคำถามนั้น ผมสามารถเปิดเผยคำตอบของผมและพิสูจน์ให้คุณเห็นว่าคำตอบของผม เมื่อใช้เป็นข้อมูลสำหรับฟังก์ชันแฮช จะให้ผลลัพธ์เดียวกันกับที่ผมให้คุณก่อนหน้านี้$ echo "2007. He said about a year and a half before Oct 2008" | sha256sum 94d7a772612c8f2f2ec609d41f5bd3d04a5aa1dfe3582f04af517d396a302e4e
ทีนี้ให้สมมติว่าเราถามบ็อบว่า " public key ของคุณคืออะไร?" บ็อบสามารถใช้ฟังก์ชันแฮชเพื่อให้การยืนยันที่ปลอดภัยทางการเข้ารหัสต่อ public key ของเขา หากเขาเปิดเผยกุญแจในภายหลัง และเราตรวจสอบว่ามันให้ผลการยืนยันเดียวกันกับที่เขาให้เราก่อนหน้านี้ เราสามารถมั่นใจได้ว่ามันเป็นกุญแจเดียวกันที่ใช้สร้างการยืนยันก่อนหน้านี้ฟังก์ชันแฮช SHA256 ถือว่าปลอดภัยมากและให้ผลลัพธ์ 256 บิต (32 ไบต์) น้อยกว่าครึ่งหนึ่งของขนาด public key ของบิทคอยน์ดั้งเดิม แต่อย่างไรก็ตาม มีฟังก์ชันแฮชอื่นๆ ที่ปลอดภัยน้อยกว่าเล็กน้อยที่ให้ผลลัพธ์ขนาดเล็กกว่า เช่น ฟังก์ชันแฮช RIPEMD-160 ซึ่งให้ผลลัพธ์ 160 บิต (20 ไบต์) ด้วยเหตุผลที่ซาโตชิ นาคาโมโตะไม่เคยระบุ เวอร์ชันดั้งเดิมของบิทคอยน์สร้างการยืนยันต่อ public key โดยการแฮชกุญแจด้วย SHA256 ก่อน แล้วแฮชผลลัพธ์นั้นด้วย RIPEMD-160 ซึ่งให้การยืนยันขนาด 20 ไบต์ต่อ public key
เราสามารถดูสิ่งนี้ตามอัลกอริทึม เริ่มจากกุญแจสาธารณะ K เราคำนวณแฮช SHA256 และคำนวณแฮช RIPEMD-160 ของผลลัพธ์ ซึ่งให้ตัวเลข 160 บิต (20 ไบต์): A = RIPEMD160(SHA256(K))
ทีนี้เราคงเข้าใจวิธีสร้างการยืนยันต่อ public key แล้ว ต่อไปเราจะมาดูวิธีการใช้งานโดยพิจารณาสคริปต์เอาต์พุตต่อไปนี้:
OP_DUP OP_HASH160 <Bob's commitment> OP_EQUAL OP_CHECKSIG
และสคริปต์อินพุตต่อไปนี้:<Bob's signature> <Bob's public key>
และเมื่อเรารวมมันเข้าด้วยกันเราจะได้ผลลัพธ์ดังนี้:<Bob's signature> <Bob's public key> OP_DUP OP_HASH160 <Bob's commitment> OP_EQUAL OP_CHECKSIG
เหมือนที่เราทำใน IP Addresses: The Original Address for Bitcoin (P2PK) เราเริ่มวางรายการลงในสแต็ก ลายเซ็นของบ็อบถูกวางก่อน จากนั้น public key ของเขาถูกวางไว้ด้านบน จากนั้นดำเนินการ OP_DUP เพื่อทำสำเนารายการบนสุด ดังนั้นรายการบนสุดและรายการที่สองจากบนในสแต็กตอนนี้เป็น public key ของบ็อบทั้งคู่ การดำเนินการ OP_HASH160 ใช้ (ลบ) public key บนสุดและแทนที่ด้วยผลลัพธ์ของการแฮชด้วย RIPEMD160(SHA256(K)) ดังนั้นตอนนี้บนสุดของสแต็กคือแฮชของ public key ของบ็อบ ต่อไป commitment ถูกเพิ่มไว้บนสุดของสแต็ก การดำเนินการ OP_EQUALVERIFY ใช้รายการสองรายการบนสุดและตรวจสอบว่าพวกมันเท่ากัน ซึ่งควรเป็นเช่นนั้นหาก public key ที่บ็อบให้ในสคริปต์อินพุตเป็น public key เดียวกันกับที่ใช้สร้างการยืนยันในสคริปต์เอาต์พุตที่อลิซจ่าย หาก OP_EQUALVERIFY ล้มเหลว ทั้งสคริปต์จะล้มเหลว สุดท้าย เราเหลือสแต็กที่มีเพียงลายเซ็นของบ็อบและ public key ของเขา รหัสปฏิบัติการ OP_CHECKSIG ตรวจสอบว่าพวกมันสอดคล้องกัน
TIP: จากหลาม ถ้าอ่านตรงนี้และงง ๆ ผมไปทำรูปมาให้ดูง่ายขึ้นครับ
แม้กระบวนการของการ pay-to-publickey-hash(P2PKH) อาจดูซับซ้อน แต่มันทำให้การที่อลิซจ่ายเงินให้บ็อบมีเพียงการยืนยันเพียง 20 ไบต์ต่อ public key ของเขาแทนที่จะเป็นตัวกุญแจเอง ซึ่งจะมีขนาด 65 ไบต์ในเวอร์ชันดั้งเดิมของบิทคอยน์ นั่นเป็นข้อมูลที่น้อยกว่ามากที่บ็อบต้องสื่อสารกับอลิซ
แต่อย่างไรก็ตาม เรายังไม่ได้พูดถึงวิธีที่บ็อบรับ 20 ไบต์เหล่านั้นจากกระเป๋าเงินบิทคอยน์ของเขาไปยังกระเป๋าเงินของอลิซ มีการเข้ารหัสค่าไบต์ที่ใช้กันอย่างแพร่หลาย เช่น เลขฐานสิบหก แต่ข้อผิดพลาดใด ๆ ในการคัดลอกการยืนยันจะทำให้บิทคอยน์ถูกส่งไปยังเอาต์พุตที่ไม่สามารถใช้จ่ายได้ ทำให้พวกมันสูญหายไปตลอดกาล โดยในส่วนถัดไป เราจะดูที่การเข้ารหัสแบบกะทัดรัดและการตรวจสอบความถูกต้อง
Base58check Encoding
ระบบคอมพิวเตอร์มีวิธีเขียนตัวเลขยาวๆ ให้สั้นลงโดยใช้ทั้งตัวเลขและตัวอักษรผสมกัน เพื่อใช้พื้นที่น้อยลงอย่างเช่น
- ระบบเลขฐานสิบ (ปกติที่เราใช้) - ใช้เลข 0-9 เท่านั้น
- ระบบเลขฐานสิบหก - ใช้เลข 0-9 และตัวอักษร A-F ตัวอย่าง: เลข 255 ในระบบปกติ เขียนเป็น FF ในระบบเลขฐานสิบหก (สั้นกว่า)
- ระบบเลขฐานหกสิบสี่ (Base64) - ใช้สัญลักษณ์ถึง 64 ตัว: ตัวอักษรเล็ก (a-z) 26 ตัว, ตัวอักษรใหญ่ (A-Z) 26 ตัว, ตัวเลข (0-9) 10 ตัว, สัญลักษณ์พิเศษอีก 2 ตัว ("+" และ "/")
โดยระบบ Base64 นี้ช่วยให้เราส่งไฟล์คอมพิวเตอร์ผ่านข้อความธรรมดาได้ เช่น การส่งรูปภาพผ่านอีเมล โดยใช้พื้นที่น้อยกว่าการเขียนเป็นเลขฐานสิบแบบปกติมาก
การเข้ารหัสแบบ Base58 คล้ายกับ Base64 โดยใช้ตัวอักษรพิมพ์ใหญ่ พิมพ์เล็ก และตัวเลข แต่ได้ตัดตัวอักษรบางตัวที่มักถูกเข้าใจผิดว่าเป็นตัวอื่นและอาจดูเหมือนกันเมื่อแสดงในฟอนต์บางประเภทออกไป
Base58 คือ Base64 ที่ตัดตัวอักษรต่อไปนี้ออก:
- เลข 0 (ศูนย์)
- ตัวอักษร O (ตัว O พิมพ์ใหญ่)
- ตัวอักษร l (ตัว L พิมพ์เล็ก)
- ตัวอักษร I (ตัว I พิมพ์ใหญ่)
- และสัญลักษณ์ "+" และ "/"
หรือพูดให้ง่ายขึ้น Base58 คือกลุ่มตัวอักษรพิมพ์เล็ก พิมพ์ใหญ่ และตัวเลข แต่ไม่มีตัวอักษรทั้งสี่ตัว (0, O, l, I) ที่กล่าวถึงข้างต้น ตัวอักษรทั้งหมดที่ใช้ใน Base58 จะแสดงให้เห็นในตัวอักษร Base58 ของบิทคอยน์
Example 2. Bitcoin’s base58 alphabet
123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz
การเพิ่มความปลอดภัยพิเศษเพื่อป้องกันการพิมพ์ผิดหรือข้อผิดพลาดในการคัดลอก base58check ได้รวม รหัสตรวจสอบ (checksum) ที่เข้ารหัสในตัวอักษร base58 เข้าไปด้วย รหัสตรวจสอบนี้คือข้อมูลเพิ่มเติมอีก 4 ไบต์ที่เพิ่มเข้าไปที่ท้ายของข้อมูลที่กำลังถูกเข้ารหัสรหัสตรวจสอบนี้ได้มาจากการแฮชข้อมูลที่ถูกเข้ารหัส และจึงสามารถใช้เพื่อตรวจจับข้อผิดพลาดจากการคัดลอกและการพิมพ์ได้ เมื่อโปรแกรมได้รับรหัส base58check ซอฟต์แวร์ถอดรหัสจะคำนวณรหัสตรวจสอบของข้อมูลและเปรียบเทียบกับรหัสตรวจสอบที่รวมอยู่ในรหัสนั้น
หากทั้งสองไม่ตรงกัน แสดงว่ามีข้อผิดพลาดเกิดขึ้น และข้อมูล base58check นั้นไม่ถูกต้อง กระบวนการนี้ช่วยป้องกันไม่ให้ address บิทคอยน์ที่พิมพ์ผิดถูกยอมรับโดยซอฟต์แวร์กระเป๋าเงินว่าเป็น address ที่ถูกต้อง ซึ่งเป็นข้อผิดพลาดที่อาจส่งผลให้สูญเสียเงินได้
การแปลงข้อมูล (ตัวเลข) เป็นรูปแบบ base58check มีขั้นตอนดังนี้:
- เราเริ่มโดยการเพิ่ม prefix เข้าไปในข้อมูล เรียกว่า "version byte" ซึ่งช่วยให้ระบุประเภทของข้อมูลที่ถูกเข้ารหัสได้ง่าย ตัวอย่างเช่น: prefix ศูนย์ (0x00 ในระบบเลขฐานสิบหก) แสดงว่าข้อมูลควรถูกใช้เป็นการยืนยัน (hash) ในสคริปต์เอาต์พุต legacy P2PKH
- จากนั้น เราคำนวณ "double-SHA" checksum ซึ่งหมายถึงการใช้อัลกอริทึมแฮช SHA256 สองครั้งกับผลลัพธ์ก่อนหน้า (prefix ต่อกับข้อมูล):
checksum = SHA256(SHA256(prefix||data))
- จากแฮช 32 ไบต์ที่ได้ (การแฮชซ้อนแฮช) เราเลือกเฉพาะ 4 ไบต์แรก ไบต์ทั้งสี่นี้ทำหน้าที่เป็นรหัสตรวจสอบข้อผิดพลาดหรือ checksum
- นำ checksum นี้ไปต่อที่ท้ายข้อมูล
การเข้ารหัสแบบ base58check คือรูปแบบการเข้ารหัสที่ใช้ base58 พร้อมกับการระบุเวอร์ชันและการตรวจสอบความถูกต้อง เพื่อการเข้ารหัสข้อมูลบิทคอยน์ โดยคุณสามารถดูภาพประกอบด้านล่างเพื่อความเข้าใจเพิ่มเติม
ในบิตคอยน์นั้น นอกจากจะใช้ base58check ในการยืนยัน public key แล้ว ก็ยังมีการใช้ในข้อมูลอื่น ๆ ด้วย เพื่อทำให้ข้อมูลนั้นกะทัดรัด อ่านง่าย และตรวจจับข้อผิดพลาดได้ง่ายด้วยรหัสนำหน้า (version prefix) ในการเข้ารหัสแบบ base58check ถูกใช้เพื่อสร้างรูปแบบที่แยกแยะได้ง่าย ซึ่งเมื่อเข้ารหัสด้วย base58 โดยจะมีตัวอักษรเฉพาะที่จุดเริ่มต้นของข้อมูลที่เข้ารหัส base58check ตัวอักษรเหล่านี้ช่วยให้เราระบุประเภทของข้อมูลที่ถูกเข้ารหัสและวิธีการใช้งานได้ง่าย นี่คือสิ่งที่แยกความแตกต่าง ตัวอย่างเช่น ระหว่าง address บิทคอยน์ที่เข้ารหัส base58check ซึ่งขึ้นต้นด้วยเลข 1 กับรูปแบบการนำเข้า private key (WIF - Wallet Import Format) ที่เข้ารหัส base58check ซึ่งขึ้นต้นด้วยเลข 5 ตัวอย่างของ version prefix สามารถดูได้ตามตารางด้านล่างนี้
ภาพต่อไปนี้จะทำให้คุณเห็นภาพของกระบวนการแปลง public key ให้เป็น bitcoin address
Compressed Public Keys
ในยุคแรก ๆ ของบิตคอยน์นั้น มีเพียงการสร้าง public key แบบ 65 Bytes เท่านั้น แต่ในเวลาต่อมา เหล่านักพัฒนาในยุคหลังได้พบวิธีการสร้าง public key แบบใหม่ที่มีเพียง 33 Bytes และสามารถทำงานร่วมกันกับโหนดทั้งหมดในขณะนั้นได้ จีงไม่จะเป็นต้องเปลี่ยนแปลงกฎหรือโครงสร้างภายในโปรโตคอลของบิตคอยน์ โดย poublic key แบบใหม่ที่มีขนาด 33 Bytes นี้เรียกว่า compressed public key (public key ที่ถูกบีบอัด) และมีการเรียก public key ที่มีขนาด 65 Bytes ว่า uncompressed public key (public key ที่ไม่ถูกบีบอัด) ซึ่งประโยชน์ของ public key ที่เล็กลงนั้น นอกจากจะช่วยให้การส่ง public key ให้ผู้อื่นทำได้ง่ายขึ้นแล้ว ยังช่วยให้ธุรกรรมมีขนาดเล็กลง และช่วยให้สามารถทำการชำระเงินได้มากขึ้นในบล็อกเดียวกัน
อย่างที่เราได้เรียนรู้จากเนื้อหาในส่วนของ public key เราได้ทราบว่า public key คือจุด (x, y) บนเส้นโค้งวงรี เนื่องจากเส้นโค้งแสดงฟังก์ชันทางคณิตศาสตร์ จุดบนเส้นโค้งจึงเป็นคำตอบของสมการ ดังนั้นหากเรารู้พิกัด x เราก็สามารถคำนวณพิกัด y ได้โดยแก้สมการ y² mod p = (x³ + 7) mod p นั่นหมายความว่าเราสามารถเก็บเพียงพิกัด x ของ public key โดยละพิกัด y ไว้ ซึ่งช่วยลดขนาดของกุญแจและพื้นที่ที่ต้องใช้เก็บข้อมูลลง 256 บิต การลดขนาดลงเกือบ 50% ในทุกธุรกรรมรวมกันแล้วช่วยประหยัดข้อมูลได้มากมายในระยะยาว!
นี่คือ public key ที่ได้ยกเป็นตัวอย่างไว้ก่อนหน้า
x = F028892BAD7ED57D2FB57BF33081D5CFCF6F9ED3D3D7F159C2E2FFF579DC341A y = 07CF33DA18BD734C600B96A72BBC4749D5141C90EC8AC328AE52DDFE2E505BDB
และนี่คือ public key ที่มีตัวนำหน้า 04 ตามด้วยพิกัด x และ y ในรูปแบบ 04 x y:
K = 04F028892BAD7ED57D2FB57BF33081D5CFCF6F9ED3D3D7F159C2E2FFF579DC341A07CF33DA18BD734C600B96A72BBC4749D5141C90EC8AC328AE52DDFE2E505BDB
uncompressed public key นั้นจะมีตัวนำหน้าเป็น 04 แต่ compressed public key จะมีตัวนำหน้าเป็น 02 หรือ 03 โดยเหตุผลนั้นมาจากสมการ y² mod p = (x³ + 7) mod p เนื่องจากด้านซ้ายของสมการคือ y² คำตอบสำหรับ y จึงเป็นรากที่สอง ซึ่งอาจมีค่าเป็นบวกหรือลบก็ได้ หากมองเชิงภาพ นี่หมายความว่าพิกัด y ที่ได้อาจอยู่เหนือหรือใต้แกน x เราต้องไม่ลืมว่าเส้นโค้งมีความสมมาตร ซึ่งหมายความว่ามันจะสะท้อนเหมือนกระจกโดยแกน x ดังนั้น แม้เราจะละพิกัด y ได้ แต่เราต้องเก็บ เครื่องหมาย ของ y (บวกหรือลบ) หรืออีกนัยหนึ่งคือเราต้องจำว่ามันอยู่เหนือหรือใต้แกน x เพราะแต่ละตำแหน่งแทนจุดที่แตกต่างกันและเป็น public key ที่แตกต่างกัน
เมื่อคำนวณเส้นโค้งวงรีในระบบเลขฐานสองบนสนามจำกัดของเลขจำนวนเฉพาะ p พิกัด y จะเป็นเลขคู่หรือเลขคี่ ซึ่งสอดคล้องกับเครื่องหมายบวก/ลบตามที่อธิบายก่อนหน้านี้ ดังนั้น เพื่อแยกความแตกต่างระหว่างค่าที่เป็นไปได้สองค่าของ y เราจึงเก็บ compressed public key ด้วยตัวนำหน้า 02 ถ้า y เป็นเลขคู่ และ 03 ถ้า y เป็นเลขคี่ ซึ่งช่วยให้ซอฟต์แวร์สามารถอนุมานพิกัด y จากพิกัด x และคลายการบีบอัดของ public key ไปยังพิกัดเต็มของจุดได้อย่างถูกต้อง ดังภาพประกอบต่อไปนี้
นี่คือ public key เดียวกันกับที่ยกตัวอย่างไว้ข้างต้นซึ่งแสดงให้เห็นในรูป compressed public key ที่เก็บใน 264 บิต (66 ตัวอักษรเลขฐานสิบหก) โดยมีตัวนำหน้า 03 ซึ่งบ่งชี้ว่าพิกัด y เป็นเลขคี่:
K = 03F028892BAD7ED57D2FB57BF33081D5CFCF6F9ED3D3D7F159C2E2FFF579DC341A
compressed public key สอดคล้องกับ private key เดียวกันกับ uncompressed public key หมายความว่ามันถูกสร้างจาก private key เดียวกัน แต่อย่างไรก็ตาม มันก็มีส่วนที่แตกต่างจาก uncompressed public key นั้นคือ หากเราแปลง compressed public key เป็น commitment โดยใช้ฟังก์ชัน HASH160 (RIPEMD160(SHA256(K))) มันจะสร้าง commitment ที่แตกต่างจาก uncompressed public key และจะนำไปสู่ bitcoin address ที่แตกต่างกันในที่สุด สิ่งนี้อาจทำให้สับสนเพราะหมายความว่า private key เดียวสามารถสร้าง public key ในสองรูปแบบที่แตกต่างกัน (แบบบีบอัดและแบบไม่บีบอัด) ซึ่งสร้าง bitcoin address ที่แตกต่างกันcompressed public key เป็นค่าเริ่มต้นในซอฟต์แวร์บิตคอยน์เกือบทั้งหมดในปัจจุบัน และถูกกำหนดให้ใช้กับคุณสมบัติใหม่บางอย่างที่เพิ่มในการอัปเกรดโปรโตคอลในภายหลัง
อย่างไรก็ตาม ซอฟต์แวร์บางตัวยังคงต้องรองรับ uncompressed public key เช่น แอปพลิเคชันกระเป๋าเงินที่นำเข้า private key จากกระเป๋าเงินเก่า เมื่อกระเป๋าเงินใหม่สแกนบล็อกเชนสำหรับผลลัพธ์และอินพุต P2PKH เก่า มันจำเป็นต้องรู้ว่าควรสแกนกุญแจขนาด 65 ไบต์ (และ commitment ของกุญแจเหล่านั้น) หรือกุญแจขนาด 33 ไบต์ (และ commitment ของกุญแจเหล่านั้น) หากไม่สแกนหาประเภทที่ถูกต้อง อาจทำให้ผู้ใช้ไม่สามารถใช้ยอดคงเหลือทั้งหมดได้ เพื่อแก้ไขปัญหานี้ เมื่อส่งออก private key จากกระเป๋าเงิน WIF ที่ใช้แสดง private key ในกระเป๋าเงินบิตคอยน์รุ่นใหม่จะถูกนำไปใช้แตกต่างกันเล็กน้อยเพื่อบ่งชี้ว่า private key เหล่านี้ถูกใช้ในการสร้าง compressed public key
Legacy: Pay to Script Hash (P2SH)
ตามที่เราได้เห็นในส่วนก่อนหน้านี้ ผู้รับบิตคอยน์ สามารถกำหนดให้การชำระเงินที่ส่งมาให้เขานั้นมีเงื่อนไขบางอย่างในสคริปต์เอาต์พุตได้โดยจะต้องปฏิบัติตามเงื่อนไขเหล่านั้นโดยใช้สคริปต์อินพุตเมื่อเขาใช้จ่ายบิตคอยน์เหล่านั้น ในส่วน IP Addresses: The Original Address for Bitcoin (P2PK) เงื่อนไขก็คือสคริปต์อินพุตต้องให้ลายเซ็นที่เหมาะสม ในส่วน Legacy Addresses for P2PKH นั้นจำเป็นต้องมี public key ที่เหมาะสมด้วย
ส่วนสำหรับผู้ส่งก็จะวางเงื่อนไขที่ผู้รับต้องการในสคริปต์เอาต์พุตที่ใช้จ่ายให้กับผู้รับ โดยผู้รับจะต้องสื่อสารเงื่อนไขเหล่านั้นให้ผู้ส่งทราบ ซึ่งคล้ายกับปัญหาที่บ๊อบต้องสื่อสาร public key ของเขาให้อลิซทราบ และเช่นเดียวกับปัญหานั้นที่ public key อาจมีขนาดค่อนข้างใหญ่ เงื่อนไขที่บ๊อบใช้ก็อาจมีขนาดใหญ่มากเช่นกัน—อาจมีขนาดหลายพันไบต์ นั่นไม่เพียงแต่เป็นข้อมูลหลายพันไบต์ที่ต้องสื่อสารให้อลิซทราบ แต่ยังเป็นข้อมูลหลายพันไบต์ที่เธอต้องจ่ายค่าธรรมเนียมธุรกรรมทุกครั้งที่ต้องการใช้จ่ายเงินให้บ๊อบ อย่างไรก็ตาม การใช้ฟังก์ชันแฮชเพื่อสร้าง commitment ขนาดเล็กสำหรับข้อมูลขนาดใหญ่ก็สามารถนำมาใช้ได้ในกรณีนี้เช่นกัน
ในเวลาต่อมานั้น การอัปเกรด BIP16 สำหรับโปรโตคอลบิตคอยน์ในปี 2012 ได้อนุญาตให้สคริปต์เอาต์พุตสร้าง commitment กับ redemption script (redeem script) ได้ แปลว่าเมื่อบ๊อบใช้จ่ายบิตคอยน์ของเขา ภายในสคริปต์อินพุตของเขานั้นจะต้องให้ redeem script ที่ตรงกับ commitment และข้อมูลที่จำเป็นเพื่อให้เป็นไปตาม redeem script (เช่น ลายเซ็น) เริ่มต้นด้วยการจินตนาการว่าบ๊อบต้องการให้มีลายเซ็นสองอันเพื่อใช้จ่ายบิตคอยน์ของเขา หนึ่งลายเซ็นจากกระเป๋าเงินบนเดสก์ท็อปและอีกหนึ่งจากอุปกรณ์เซ็นแบบฮาร์ดแวร์ เขาใส่เงื่อนไขเหล่านั้นลงใน redeem script:
<public key 1> OP_CHECKSIGVERIFY <public key 2> OP_CHECKSIG
จากนั้นเขาสร้าง commitment กับ redeem script โดยใช้กลไก HASH160 เดียวกับที่ใช้สำหรับ commitment แบบ P2PKH, RIPEMD160(SHA256(script)) commitment นั้นถูกวางไว้ในสคริปต์เอาต์พุตโดยใช้เทมเพลตพิเศษ:OP_HASH160 <commitment> OP_EQUAL
คำเตือน: เมื่อใช้ pay to script hash (P2SH) คุณต้องใช้เทมเพลต P2SH โดยเฉพาะ ซึ่งจะไม่มีข้อมูลหรือเงื่อนไขเพิ่มเติมในสคริปต์เอาต์พุต หากสคริปต์เอาต์พุตไม่ได้เป็น OP_HASH160 <20 ไบต์> OP_EQUAL แน่นอนว่า redeem script จะไม่ถูกใช้และบิตคอยน์ใด ๆ อาจไม่สามารถใช้จ่ายได้หรืออาจถูกใช้จ่ายได้โดยทุกคน (หมายความว่าใครก็สามารถนำไปใช้ได้)
เมื่อบ๊อบต้องการจ่ายเงินที่เขาได้รับผ่าน commitment สำหรับสคริปต์ของเขา เขาจะใช้สคริปต์อินพุตที่รวมถึง redeem script ซึ่งถูกแปลงให้เป็นข้อมูลอีลิเมนต์เดียว นอกจากนี้เขายังให้ลายเซ็นที่จำเป็นเพื่อให้เป็นไปตาม redeem script โดยเรียงลำดับตามที่จะถูกใช้โดย opcodes:
<signature2> <signature1> <redeem script>
เมื่อโหนดของบิตคอยน์ได้รับการใช้จ่ายของบ๊อบพวกมันจะตรวจสอบว่า redeem script ที่ถูกแปลงเป็นค่าแฮชแล้วมีค่าเดียวกันกับ commitment มั้ย หลังจากนั้นพวกมันจะแทนที่มันบนสแต็คด้วยค่าที่ถอดรหัสแล้ว:<signature2> <signature1> <pubkey1> OP_CHECKSIGVERIFY <pubkey2> OP_CHECKSIG
สคริปต์จะถูกประมวลผล และหากผ่านการตรวจสอบและรายละเอียดธุรกรรมอื่น ๆ ทั้งหมดถูกต้อง ธุรกรรมก็จะถือว่าใช้ได้address สำหรับ P2SH ก็ถูกสร้างด้วย base58check เช่นกัน คำนำหน้าเวอร์ชันถูกตั้งเป็น 5 ซึ่งทำให้ที่อยู่ที่เข้ารหัสแล้วขึ้นต้นด้วยเลข 3 ตัวอย่างของที่อยู่ P2SH คือ 3F6i6kwkevjR7AsAd4te2YB2zZyASEm1HM
TIP: P2SH ไม่จำเป็นต้องเหมือนกับธุรกรรมแบบหลายลายเซ็น (multisignature) เสมอไป ถึง address P2SH ส่วนใหญ่ แทนสคริปต์แบบหลายลายเซ็นก็ตาม แต่อาจแทนสคริปต์ที่เข้ารหัสธุรกรรมประเภทอื่น ๆ ได้ด้วย
P2PKH และ P2SH เป็นสองเทมเพลตสคริปต์เท่านั้นที่ใช้กับการเข้ารหัสแบบ base58check พวกมันเป็นที่รู้จักในปัจจุบันว่าเป็น address แบบ legacy และกลายเป็นรูปแบบที่พบน้อยลงเรื่อยๆ address แบบ legacy ถูกแทนที่ด้วยaddress ตระกูล bech32
การโจมตี P2SH แบบ Collision
address ทั้งหมดที่อิงกับฟังก์ชันแฮชมีความเสี่ยงในทางทฤษฎีต่อผู้โจมตีที่อาจค้นพบอินพุตเดียวกันที่สร้างเอาต์พุตฟังก์ชันแฮช (commitment) โดยอิสระ ในกรณีของบิตคอยน์ หากพวกเขาค้นพบอินพุตในวิธีเดียวกับที่ผู้ใช้ดั้งเดิมทำ พวกเขาจะรู้ private key ของผู้ใช้และสามารถใช้จ่ายบิตคอยน์ของผู้ใช้นั้นได้ โอกาสที่ผู้โจมตีจะสร้างอินพุตสำหรับ commitment ที่มีอยู่แล้วโดยอิสระนั้นขึ้นอยู่กับความแข็งแกร่งของอัลกอริทึมแฮช สำหรับอัลกอริทึมที่ปลอดภัย 160 บิตอย่าง HASH160 ความน่าจะเป็นอยู่ที่ 1 ใน 2^160 นี่เรียกว่าการโจมตีแบบ preimage attack
ผู้โจมตีสามารถพยายามสร้างข้อมูลนำเข้าสองชุดที่แตกต่างกัน (เช่น redeem scripts) ที่สร้างการเข้ารหัสแบบเดียวกันได้ สำหรับ address ที่สร้างโดยฝ่ายเดียวทั้งหมด โอกาสที่ผู้โจมตีจะสร้างข้อมูลนำเข้าที่แตกต่างสำหรับการเข้ารหัสที่มีอยู่แล้วมีประมาณ 1 ใน 2^160 สำหรับอัลกอริทึม HASH160 นี่คือการโจมตีแบบ second preimage attack
อย่างไรก็ตาม สถานการณ์จะเปลี่ยนไปเมื่อผู้โจมตีสามารถมีอิทธิพลต่อค่าข้อมูลนำเข้าดั้งเดิมได้ ตัวอย่างเช่น ผู้โจมตีมีส่วนร่วมในการสร้างสคริปต์แบบหลายลายเซ็น (multisignature script) ซึ่งพวกเขาไม่จำเป็นต้องส่ง public key ของตนจนกว่าจะทราบ public key ของฝ่ายอื่นทั้งหมด ในกรณีนั้น ความแข็งแกร่งของอัลกอริทึมการแฮชจะลดลงเหลือรากที่สองของมัน สำหรับ HASH160 ความน่าจะเป็นจะกลายเป็น 1 ใน 2^80 นี่คือการโจมตีแบบ collision attack
เพื่อให้เข้าใจตัวเลขเหล่านี้ในบริบทที่ชัดเจน ข้อมูล ณ ต้นปี 2023 นักขุดบิตคอยน์ทั้งหมดรวมกันสามารถประมวลผลฟังก์ชันแฮชประมาณ 2^80 ทุกชั่วโมง พวกเขาใช้ฟังก์ชันแฮชที่แตกต่างจาก HASH160 ดังนั้นฮาร์ดแวร์ที่มีอยู่จึงไม่สามารถสร้างการโจมตีแบบ collision attack สำหรับมันได้ แต่การมีอยู่ของเครือข่ายบิตคอยน์พิสูจน์ว่าการโจมตีแบบชนกันต่อฟังก์ชัน 160 บิตอย่าง HASH160 สามารถทำได้จริงในทางปฏิบัติ นักขุดบิตคอยน์ได้ลงทุนเทียบเท่ากับหลายพันล้านดอลลาร์สหรัฐในฮาร์ดแวร์พิเศษ ดังนั้นการสร้างการโจมตีแบบ collision attack จึงไม่ใช่เรื่องถูก แต่มีองค์กรที่คาดหวังว่าจะได้รับบิตคอยน์มูลค่าหลายพันล้านดอลลาร์ไปยัง address ที่สร้างโดยกระบวนการที่เกี่ยวข้องกับหลายฝ่าย ซึ่งอาจทำให้การโจมตีนี้มีกำไร
มีโปรโตคอลการเข้ารหัสที่เป็นที่ยอมรับอย่างดีในการป้องกันการโจมตีแบบ collision attack แต่วิธีแก้ปัญหาที่ง่ายโดยไม่ต้องใช้ความรู้พิเศษจากผู้พัฒนากระเป๋าเงินคือการใช้ฟังก์ชันแฮชที่แข็งแกร่งกว่า การอัปเกรดบิตคอยน์ในภายหลังทำให้เป็นไปได้ และ address บิตคอยน์ใหม่ให้ความต้านทานการชนกันอย่างน้อย 128 บิต การดำเนินการแฮช 2^128 ครั้งจะใช้เวลานักขุดบิตคอยน์ปัจจุบันทั้งหมดประมาณ 32 พันล้านปี
แม้ว่าเราไม่เชื่อว่ามีภัยคุกคามเร่งด่วนต่อผู้ที่สร้าง address P2SH ใหม่ แต่เราแนะนำให้กระเป๋าเงินใหม่ทั้งหมดใช้ที่อยู่ประเภทใหม่เพื่อขจัดความกังวลเกี่ยวกับการโจมตีแบบ collision attack ของ P2SH address
Bech32 Addresses
ในปี 2017 โปรโตคอลบิตคอยน์ได้รับการอัปเกรด เพื่อป้องกันไม่ให้ตัวระบุธุรกรรม (txids) ไม่สามารถเปลี่ยนแปลงได้ โดยไม่ได้รับความยินยอมจากผู้ใช้ที่ทำการใช้จ่าย (หรือองค์ประชุมของผู้ลงนามเมื่อต้องมีลายเซ็นหลายรายการ) การอัปเกรดนี้เรียกว่า segregated witness (หรือเรียกสั้นๆ ว่า segwit) ซึ่งยังให้ความสามารถเพิ่มเติมสำหรับข้อมูลธุรกรรมในบล็อกและประโยชน์อื่น ๆ อีกหลายประการ แต่อย่างไรก็ตาม หากมีผู้ใช้เก่าที่ต้องการเข้าถึงประโยชน์ของ segwit โดยตรงต้องยอมรับการชำระเงินไปยังสคริปต์เอาต์พุตใหม่
ตามที่ได้กล่าวไว้ใน p2sh หนึ่งในข้อดีของเอาต์พุตประเภท P2SH คือผู้จ่ายไม่จำเป็นต้องรู้รายละเอียดของสคริปต์ที่ผู้รับใช้ การอัปเกรด segwit ถูกออกแบบมาให้ใช้กลไกนี้ได้ดังเดิม จึง ทำให้ผู้จ่ายสามารถเริ่มเข้าถึงประโยชน์ใหม่ ๆ หลายอย่างได้ทันทีโดยใช้ที่อยู่ P2SH แต่เพื่อให้ผู้รับสามารถเข้าถึงประโยชน์เหล่านั้นได้ พวกเขาจำเป็นจะต้องให้กระเป๋าเงินของผู้จ่ายจ่ายเงินให้เขาโดยใช้สคริปต์ประเภทอื่นแทน ซึ่งจะต้องอาศัยการอัปเกรดกระเป๋าเงินของผู้จ่ายเพื่อรองรับสคริปต์ใหม่เหล่านี้
ในช่วงแรก เหล่านักพัฒนาบิตคอยน์ได้นำเสนอ BIP142 ซึ่งจะยังคงใช้ base58check ร่วมกับไบต์เวอร์ชันใหม่ คล้ายกับการอัปเกรด P2SH แต่การให้กระเป๋าเงินทั้งหมดอัปเกรดไปใช้สคริปต์ใหม่ที่มีเวอร์ชัน base58check ใหม่นั้น คาดว่าจะต้องใช้ความพยายามเกือบเท่ากับการให้พวกเขาอัปเกรดไปใช้รูปแบบ address ที่เป็นแบบใหม่ทั้งหมด ด้วยเหตุนี้้เอง ผู้สนับสนุนบิตคอยน์หลายคนจึงเริ่มออกแบบรูปแบบ address ที่ดีที่สุดเท่าที่เป็นไปได้ พวกเขาระบุปัญหาหลายอย่างกับ base58check ไว้ดังนี้:
- การที่ base58check ใช้อักษรที่มีทั้งตัวพิมพ์ใหญ่และตัวพิมพ์เล็กทำให้ไม่สะดวกในการอ่านออกเสียงหรือคัดลอก ลองอ่าน address แบบเก่าในบทนี้ให้เพื่อนฟังและให้พวกเขาคัดลอก คุณจะสังเกตว่าคุณต้องระบุคำนำหน้าทุกตัวอักษรด้วยคำว่า "ตัวพิมพ์ใหญ่" และ "ตัวพิมพ์เล็ก" และเมื่อคุณตรวจสอบสิ่งที่พวกเขาเขียน คุณจะพบว่าตัวพิมพ์ใหญ่และตัวพิมพ์เล็กของตัวอักษรบางตัวอาจดูคล้ายกันในลายมือของคนส่วนใหญ่
- รูปแบบนี้สามารถตรวจจับข้อผิดพลาดได้ แต่ไม่สามารถช่วยผู้ใช้แก้ไขข้อผิดพลาดเหล่านั้น ตัวอย่างเช่น หากคุณสลับตำแหน่งตัวอักษรสองตัวโดยไม่ตั้งใจเมื่อป้อน address ด้วยตนเอง กระเป๋าเงินของคุณจะเตือนว่ามีข้อผิดพลาดเกิดขึ้นแน่นอน แต่จะไม่ช่วยให้คุณค้นพบว่าข้อผิดพลาดอยู่ที่ไหน คุณอาจต้องใช้เวลาหลายนาทีที่น่าหงุดหงิดเพื่อค้นหาข้อผิดพลาดในที่สุด
- การใช้ตัวอักษรที่มีทั้งตัวพิมพ์ใหญ่และตัวพิมพ์เล็กยังต้องใช้พื้นที่เพิ่มเติมในการเข้ารหัสใน QR code ซึ่งนิยมใช้ในการแชร์ address และ invoice ระหว่างกระเป๋าเงิน พื้นที่เพิ่มเติมนี้หมายความว่า QR code จำเป็นต้องมีขนาดใหญ่ขึ้นที่ความละเอียดเดียวกัน หรือไม่เช่นนั้นก็จะยากต่อการสแกนอย่างรวดเร็ว
- การที่ต้องการให้กระเป๋าเงินผู้จ่ายทุกใบอัปเกรดเพื่อรองรับคุณสมบัติโปรโตคอลใหม่ เช่น P2SH และ segwit แม้ว่าการอัปเกรดเองอาจไม่ต้องใช้โค้ดมากนัก แต่ประสบการณ์แสดงให้เห็นว่าผู้พัฒนากระเป๋าเงินหลายรายมักยุ่งกับงานอื่น ๆ และบางครั้งอาจล่าช้าในการอัปเกรดเป็นเวลาหลายปี สิ่งนี้ส่งผลเสียต่อทุกคนที่ต้องการใช้คุณสมบัติใหม่ ๆ เหล่านี้
นักพัฒนาที่ทำงานเกี่ยวกับรูปแบบ address สำหรับ segwit ได้พบวิธีแก้ปัญหาเหล่านี้ทั้งหมดในรูปแบบ address แบบใหม่ที่เรียกว่า bech32 (ออกเสียงด้วย "ch" อ่อน เช่นใน "เบช สามสิบสอง") คำว่า "bech" มาจาก BCH ซึ่งเป็นอักษรย่อของบุคคลสามคนที่ค้นพบรหัสวนนี้ในปี 1959 และ 1960 ซึ่งเป็นพื้นฐานของ bech32 ส่วน "32" หมายถึงจำนวนตัวอักษรในชุดตัวอักษร bech32 (คล้ายกับ 58 ใน base58check):
-
Bech32 ใช้เฉพาะตัวเลขและตัวอักษรรูปแบบเดียว (โดยปกติจะแสดงเป็นตัวพิมพ์เล็ก) แม้ว่าชุดตัวอักษรของมันจะมีขนาดเกือบครึ่งหนึ่งของชุดตัวอักษรใน base58check ก็ตามแต่ address bech32 สำหรับสคริปต์ pay to witness public key hash (P2WPKH) ก็ยังยาวกว่า legacy address และมีขนาดเท่ากันกับสคริปต์ P2PKH
-
Bech32 สามารถทั้งตรวจจับและช่วยแก้ไขข้อผิดพลาดได้ ใน address ที่มีความยาวตามที่คาดหวังได้ และสามารถรับประกันทางคณิตศาสตร์ได้ว่าจะตรวจพบข้อผิดพลาดใด ๆ ที่ส่งผลกระทบต่อตัวอักษร 4 ตัวหรือน้อยกว่า ซึ่งเชื่อถือได้มากกว่า base58check ส่วนสำหรับข้อผิดพลาดที่ยาวกว่านั้น จะไม่สามารถตรวจพบได้ (โอกาสเกิดน้อยกว่าหนึ่งครั้งในหนึ่งพันล้าน) ซึ่งมีความเชื่อถือได้ประมาณเท่ากับ base58check ยิ่งไปกว่านั้น สำหรับ adddress ที่พิมพ์โดยมีข้อผิดพลาดเพียงเล็กน้อย มันสามารถบอกผู้ใช้ได้ว่าข้อผิดพลาดเหล่านั้นเกิดขึ้นที่ไหน ช่วยให้พวกเขาสามารถแก้ไขข้อผิดพลาดจากการคัดลอกเล็ก ๆ น้อย ๆ ได้อย่างรวดเร็ว

bech32 address นิยมเขียนด้วยตัวอักษรพิมพ์เล็กเท่านั้น แต่ตัวอักษรพิมพ์เล็กเหล่านี้สามารถแทนที่ด้วยตัวอักษรพิมพ์ใหญ่ก่อนการเข้ารหัส address ในรหัส QR ได้ วิธีนี้ช่วยให้สามารถใช้โหมดการเข้ารหัส QR แบบพิเศษที่ใช้พื้นที่น้อยกว่า คุณจะสังเกตเห็นความแตกต่างในขนาดและความซับซ้อนของรหัส QR ทั้งสองสำหรับที่อยู่เดียวกันในรูปภาพข้างล่างนี้
- Bech32 ใช้ประโยชน์จากกลไกการอัปเกรดที่ออกแบบมาเป็นส่วนหนึ่งของ segwit เพื่อทำให้กระเป๋าเงินผู้จ่ายสามารถจ่ายเงินไปยังประเภทเอาต์พุตที่ยังไม่ได้ใช้งานได้ โดยมีเป้าหมายคือการอนุญาตให้นักพัฒนาสร้างกระเป๋าเงินในวันนี้ที่สามารถใช้จ่ายไปยัง bech32 address และทำให้กระเป๋าเงินนั้นยังคงสามารถใช้จ่ายไปยัง bech32address ได้สำหรับผู้ใช้คุณสมบัติใหม่ที่เพิ่มในการอัปเกรดโปรโตคอลในอนาคต โดยที่มีความหวังว่าเราอาจไม่จำเป็นต้องผ่านรอบการอัปเกรดทั้งระบบอีกต่อไป ซึ่งจำเป็นสำหรับการให้ผู้คนใช้งาน P2SH และ segwit ได้อย่างเต็มรูปแบบ

Problems with Bech32 Addresses
address แบบ bech32 ประสบความสำเร็จในทุกด้านยกเว้นปัญหาหนึ่ง คือการรับประกันทางคณิตศาสตร์เกี่ยวกับความสามารถในการตรวจจับข้อผิดพลาดจะใช้ได้เฉพาะเมื่อความยาวของ address ที่คุณป้อนเข้าไปในกระเป๋าเงินมีความยาวเท่ากับ address ดั้งเดิมเท่านั้น หากคุณเพิ่มหรือลบตัวอักษรใด ๆ ระหว่างการคัดลอกจะทำให้ไม่สามารถตรวจจับได้ การรับประกันนี้จะไม่มีผล และกระเป๋าเงินของคุณอาจใช้จ่ายเงินไปยัง address ที่ไม่ถูกต้อง แต่อย่างไรก็ตาม แม้จะไม่มีคุณสมบัตินี้ มีความเชื่อว่าเป็นไปได้ยากมากที่ผู้ใช้ที่เพิ่มหรือลบตัวอักษรจะสร้างสตริงที่มีผลรวมตรวจสอบที่ถูกต้อง ซึ่งช่วยให้มั่นใจได้ว่าเงินของผู้ใช้จะปลอดภัย
น่าเสียดายที่การเลือกใช้ค่าคงที่ตัวหนึ่งในอัลกอริทึม bech32 บังเอิญทำให้การเพิ่มหรือลบตัวอักษร "q" ในตำแหน่งที่สองจากท้ายของ address ที่ลงท้ายด้วยตัวอักษร "p" เป็นเรื่องง่ายมาก ในกรณีเหล่านั้น คุณยังสามารถเพิ่มหรือลบตัวอักษร "q" หลายครั้งได้ด้วย ข้อผิดพลาดนี้จะถูกตรวจจับโดยผลรวมตรวจสอบ (checksum) ในบางครั้ง แต่จะถูกมองข้ามบ่อยกว่าความคาดหวังหนึ่งในพันล้านสำหรับข้อผิดพลาดจากการแทนที่ของ bech32 อย่างมาก สำหรับตัวอย่างสามารถดูได้ในรูปภาพข้างล่างนี้
ตัวอย่างที่ 4. การขยายความยาวของ bech32 address โดยไม่ทำให้ผลรวมตรวจสอบเป็นโมฆะ ``` bech32 address ที่ถูกต้อง: bc1pqqqsq9txsqp
address ที่ไม่ถูกต้องแต่มีผลรวมตรวจสอบที่ถูกต้อง: bc1pqqqsq9txsqqqqp bc1pqqqsq9txsqqqqqqp bc1pqqqsq9txsqqqqqqqqp bc1pqqqsq9txsqqqqqqqqqp bc1pqqqsq9txsqqqqqqqqqqqp ```
จากตัวอย่างนี้ คุณจะเห็นว่าแม้มีการเพิ่มตัวอักษร "q" เข้าไปหลายตัวก่อนตัวอักษร "p" ตัวสุดท้าย ระบบตรวจสอบก็ยังคงยอมรับว่า address เหล่านี้ถูกต้อง นี่เป็นข้อบกพร่องสำคัญของ bech32 เพราะอาจทำให้เงินถูกส่งไปยัง address ที่ไม่มีใครเป็นเจ้าของจริง ๆ หรือ address ที่ไม่ได้ตั้งใจจะส่งไป
สำหรับเวอร์ชันเริ่มต้นของ segwit (เวอร์ชัน 0) ปัญหานี้ไม่ใช่ความกังวลในทางปฏิบัติ เพราะมีความยาวที่ถูกต้องมีเพียงสองแบบที่กำหนดไว้สำหรับเอาต์พุต นั้นคือ 22 Byte และ 34 Byte ซึ่งสอดคล้องกับ bech32 address ที่มีความยาวยาวที่ 42 หรือ 62 ตัวอักษร ดังนั้นคนจะต้องเพิ่มหรือลบตัวอักษร "q" จากตำแหน่งที่สองจากท้ายของ bech32 address ถึง 20 ครั้งเพื่อส่งเงินไปยัง address ที่ไม่ถูกต้องโดยที่กระเป๋าเงินไม่สามารถตรวจจับได้ อย่างไรก็ตาม มันอาจกลายเป็นปัญหาสำหรับผู้ใช้ในอนาคตหากมีการนำการอัปเกรดบนพื้นฐานของ segwit มาใช้
Bech32m
แม้ว่า bech32 จะทำงานได้ดีสำหรับ segwit v0 แต่นักพัฒนาไม่ต้องการจำกัดขนาดเอาต์พุตโดยไม่จำเป็นในเวอร์ชันหลังๆ ของ segwit หากไม่มีข้อจำกัด การเพิ่มหรือลบตัวอักษร "q" เพียงตัวเดียวใน bech32 address อาจทำให้ผู้ใช้ส่งเงินโดยไม่ตั้งใจไปยังเอาต์พุตที่ไม่สามารถใช้จ่ายได้หรือสามารถใช้จ่ายได้โดยทุกคน (ทำให้บิตคอยน์เหล่านั้นถูกนำไปโดยทุกคนได้) นักพัฒนาได้วิเคราะห์ปัญหา bech32 อย่างละเอียดและพบว่าการเปลี่ยนค่าคงที่เพียงตัวเดียวในอัลกอริทึมของพวกเขาจะขจัดปัญหานี้ได้ ทำให้มั่นใจว่าการแทรกหรือลบตัวอักษรสูงสุดห้าตัวจะไม่ถูกตรวจจับน้อยกว่าหนึ่งครั้งในหนึ่งพันล้านเท่านั้น
เวอร์ชันของ bech32 ที่มีค่าคงที่เพียงหนึ่งตัวที่แตกต่างกันเรียกว่า bech32 แบบปรับแต่ง (bech32m) ตัวอักษรทั้งหมดใน address แบบ bech32 และ bech32m สำหรับข้อมูลพื้นฐานเดียวกันจะเหมือนกันทั้งหมด ยกเว้นหกตัวสุดท้าย (ซึ่งเป็นส่วนของ checksum) นั่นหมายความว่ากระเป๋าเงินจำเป็นต้องรู้ว่ากำลังใช้เวอร์ชันใดเพื่อตรวจสอบความถูกต้องของ checksum แต่ address ทั้งสองประเภทมีไบต์เวอร์ชันภายในที่ทำให้การระบุเวอร์ชันที่ใช้อยู่เป็นเรื่องที่ง่าย ในการทำงานกับทั้ง bech32 และ bech32m เราจะพิจารณากฎการเข้ารหัสและการแยกวิเคราะห์สำหรับ address บิตคอยน์แบบ bech32m เนื่องจากพวกมันครอบคลุมความสามารถในการแยกวิเคราะห์บน address แบบ bech32 และเป็นรูปแบบ address ที่แนะนำในปัจจุบันสำหรับกระเป๋าเงินบิตคอยน์
ข้อความจากหลาม: คือผมว่าตรงนี้เขาเขียนไม่รู้เรื่อง แต่เดาว่าเขาน่าจะสื่อว่า เราควรเรียนรู้วิธีการทำงานกับ bech32m เพราะมันเป็นรูปแบบที่แนะนำให้ใช้ในปัจจุบัน และมันมีข้อดีเพราะbech32m สามารถรองรับการอ่าน address แบบ bech32 แบบเก่าได้ด้วย ง่ายๆ คือ ถ้าคุณเรียนรู้วิธีทำงานกับ bech32m คุณจะสามารถทำงานกับทั้ง bech32m และ bech32 ได้ทั้งสองแบบ
bech32m address ริ่มต้นด้วยส่วนที่มนุษย์อ่านได้ (Human Readable Part: HRP) BIP173 มีกฎสำหรับการสร้าง HRP ของคุณเอง แต่สำหรับบิตคอยน์ คุณเพียงแค่จำเป็นต้องรู้จัก HRP ที่ถูกเลือกไว้แล้วตามที่แสดงในตารางข้างล่างนี้
ส่วน HRP ตามด้วยตัวคั่น ซึ่งก็คือเลข "1" ในข้อเสนอก่อนหน้านี้สำหรับตัวคั่นโปรโตคอลได้ใช้เครื่องหมายทวิภาค (colon) แต่ระบบปฏิบัติการและแอปพลิเคชันบางตัวที่อนุญาตให้ผู้ใช้ดับเบิลคลิกคำเพื่อไฮไลต์สำหรับการคัดลอกและวางนั้นจะไม่ขยายการไฮไลต์ไปถึงและผ่านเครื่องหมายทวิภาค
การใช้ตัวเลขช่วยให้มั่นใจได้ว่าการไฮไลต์ด้วยดับเบิลคลิกจะทำงานได้กับโปรแกรมใดๆ ที่รองรับสตริง bech32m โดยทั่วไป (ซึ่งรวมถึงตัวเลขอื่นๆ ด้วย) เลข "1" ถูกเลือกเพราะสตริง bech32 ไม่ได้ใช้เลข 1 ในกรณีอื่น เพื่อป้องกันการแปลงโดยไม่ตั้งใจระหว่างเลข "1" กับตัวอักษรพิมพ์เล็ก "l"
และส่วนอื่นของ bech32m address เรียกว่า "ส่วนข้อมูล" (data part) ซึ่งประกอบด้วยสามองค์ประกอบ:
- Witness version: ไบต์ถัดไปหลังจากตัวคั่นตัวอักษรนี้แทนเวอร์ชันของ segwit ตัวอักษร "q" คือการเข้ารหัสของ "0" สำหรับ segwit v0 ซึ่งเป็นเวอร์ชันแรกของ segwit ที่มีการแนะนำที่อยู่ bech32 ตัวอักษร "p" คือการเข้ารหัสของ "1" สำหรับ segwit v1 (หรือเรียกว่า taproot) ซึ่งเริ่มมีการใช้งาน bech32m มีเวอร์ชันที่เป็นไปได้ทั้งหมด 17 เวอร์ชันของ segwit และสำหรับ Bitcoin จำเป็นต้องให้ไบต์แรกของส่วนข้อมูล bech32m ถอดรหัสเป็นตัวเลข 0 ถึง 16 (รวมทั้งสองค่า)
- Witness program: คือตำแหน่งหลังจาก witnessversion ตั้งแต่ตำแหน่ง 2 ถึง 40 Byte สำหรับ segwit v0 นี้ต้องมีความยาว 20 หรือ 32 Byte ไม่สามารถ ffมีขนาดอื่นได้ สำหรับ segwit v1 ความยาวเดียวที่ถูกกำหนดไว้ ณ เวลาที่เขียนนี้คือ 32 ไบต์ แต่อาจมีการกำหนดความยาวอื่น ๆ ได้ในภายหลัง
- Checksum: มีความยาว 6 ตัวอักษร โดยส่วนนี้ถูกสร้างขึ้นโดยใช้รหัส BCH ซึ่งเป็นประเภทของรหัสแก้ไขข้อผิดพลาด (error corection code) (แต่อย่างไรก็ตาม สำหรับ address บิตคอยน์ เราจะเห็นในภายหลังว่าเป็นสิ่งสำคัญที่จะใช้ checksum เพื่อการตรวจจับข้อผิดพลาดเท่านั้น—ไม่ใช่การแก้ไข
ในส่วนต่อไปหลังจากนี้เราจะลองสร้าง address แบบ bech32 และ bech32m สำหรับตัวอย่างทั้งหมดต่อไปนี้ เราจะใช้โค้ดอ้างอิง bech32m สำหรับ Python
เราจะเริ่มด้วยการสร้างสคริปต์เอาต์พุตสี่ตัว หนึ่งตัวสำหรับแต่ละเอาต์พุต segwit ที่แตกต่างกันที่ใช้ในช่วงเวลาของการเผยแพร่ บวกกับอีกหนึ่งตัวสำหรับเวอร์ชัน segwit ในอนาคตที่ยังไม่มีความหมายที่กำหนดไว้ สคริปต์เหล่านี้แสดงอยู่ในตารางข้างล่างนี้
สำหรับเอาต์พุต P2WPKH witness program มีการผูก commitment ที่สร้างขึ้นในลักษณะเดียวกันกับ P2PKH ที่เห็นใน Legacy Addresses for P2PKH โดย public key ถูกส่งเข้าไปในฟังก์ชันแฮช SHA256 ไดเจสต์ขนาด 32 ไบต์ที่ได้จะถูกส่งเข้าไปในฟังก์ชันแฮช RIPEMD-160 ไดเจสต์ของฟังก์ชันนั้น จะถูกวางไว้ใน witness program
สำหรับเอาต์พุตแบบ pay to witness script hash (P2WSH) เราไม่ได้ใช้อัลกอริทึม P2SH แต่เราจะนำสคริปต์ ส่งเข้าไปในฟังก์ชันแฮช SHA256 และใช้ไดเจสต์ขนาด 32 ไบต์ของฟังก์ชันนั้นใน witness program สำหรับ P2SH ไดเจสต์ SHA256 จะถูกแฮชอีกครั้งด้วย RIPEMD-160 ซึ่งแน่นอนว่าอาจจะไม่ปลอดภัย ในบางกรณี สำหรับรายละเอียด ดูที่ P2SH Collision Attacks ผลลัพธ์ของการใช้ SHA256 โดยไม่มี RIPEMD-160 คือ การผูกพันแบบ P2WSH มีขนาด 32 ไบต์ (256 บิต) แทนที่จะเป็น 20 ไบต์ (160 บิต)
สำหรับเอาต์พุตแบบ pay-to-taproot (P2TR) witness program คือจุดบนเส้นโค้ง secp256k1 มันอาจเป็น public key แบบธรรมดา แต่ในกรณีส่วนใหญ่มันควรเป็น public key ที่ผูกพันกับข้อมูลเพิ่มเติมบางอย่าง เราจะเรียนรู้เพิ่มเติมเกี่ยวกับการผูกพันนั้นในหัวข้อของ taproot
สำหรับตัวอย่างของเวอร์ชัน segwit ในอนาคต เราเพียงแค่ใช้หมายเลขเวอร์ชัน segwit ที่สูงที่สุดที่เป็นไปได้ (16) และ witness program ที่มีขนาดเล็กที่สุดที่อนุญาต (2 ไบต์) โดยมีค่าเป็นศูนย์ (null value)
เมื่อเรารู้หมายเลขเวอร์ชันและ witness program แล้ว เราสามารถแปลงแต่ละอย่างให้เป็น bech32 address ได้ โดยการใช้ไลบรารีอ้างอิง bech32m สำหรับ Python เพื่อสร้าง address เหล่านั้นอย่างรวดเร็ว และจากนั้นมาดูอย่างละเอียดว่าเกิดอะไรขึ้น:
``` $ github=" https://raw.githubusercontent.com" $ wget $github/sipa/bech32/master/ref/python/segwit_addr.py $ python
from segwit_addr import * from binascii import unhexlify help(encode) encode(hrp, witver, witprog) Encode a segwit address. encode('bc', 0, unhexlify('2b626ed108ad00a944bb2922a309844611d25468')) 'bc1q9d3xa5gg45q2j39m9y32xzvygcgay4rgc6aaee' encode('bc', 0, unhexlify('648a32e50b6fb7c5233b228f60a6a2ca4158400268844c4bc295ed5e8c3d626f')) 'bc1qvj9r9egtd7mu2gemy28kpf4zefq4ssqzdzzycj7zjhk4arpavfhsct5a3p' encode('bc', 1, unhexlify('2ceefa5fa770ff24f87c5475d76eab519eda6176b11dbe1618fcf755bfac5311')) 'bc1p9nh05ha8wrljf7ru236awm4t2x0d5ctkkywmu9sclnm4t0av2vgs4k3au7' encode('bc', 16, unhexlify('0000')) 'bc1sqqqqkfw08p'
หากเราเปิดไฟล์ segwit_addr.py และดูว่าโค้ดกำลังทำอะไร สิ่งแรกที่เราจะสังเกตเห็นคือความแตกต่างเพียงอย่างเดียวระหว่าง bech32 (ที่ใช้สำหรับ segwit v0) และ bech32m (ที่ใช้สำหรับเวอร์ชัน segwit รุ่นหลัง) คือค่าคงที่:
BECH32_CONSTANT = 1 BECH32M_CONSTANT = 0x2bc830a3 ```และในส่วนต่อไป เราจะเห็นโค้ดที่สร้าง checksum ในขั้นตอนสุดท้ายของการสร้าง checksum ค่าคงที่ที่เหมาะสมถูกรวมเข้ากับข้อมูลอื่น ๆ โดยใช้การดำเนินการ xor ค่าเดียวนั้นคือความแตกต่างเพียงอย่างเดียวระหว่าง bech32 และ bech32m
เมื่อสร้าง checksum แล้ว อักขระ 5 บิตแต่ละตัวในส่วนข้อมูล (รวมถึง witness version, witness program และ checksum) จะถูกแปลงเป็นตัวอักษรและตัวเลข
สำหรับการถอดรหัสกลับเป็นสคริปต์เอาต์พุต เราทำงานย้อนกลับ ลองใช้ไลบรารีอ้างอิงเพื่อถอดรหัส address สอง address ของเรา: ```
help(decode) decode(hrp, addr) Decode a segwit address. _ = decode("bc", "bc1q9d3xa5gg45q2j39m9y32xzvygcgay4rgc6aaee") [0], bytes([1]).hex() (0, '2b626ed108ad00a944bb2922a309844611d25468') _ = decode("bc", "bc1p9nh05ha8wrljf7ru236awm4t2x0d5ctkkywmu9sclnm4t0av2vgs4k3au7") [0], bytes([1]).hex() (1, '2ceefa5fa770ff24f87c5475d76eab519eda6176b11dbe1618fcf755bfac5311')
เราได้รับทั้ง witness version และ witness program กลับมา สิ่งเหล่านี้สามารถแทรกลงในเทมเพลตสำหรับสคริปต์เอาต์พุตของเรา:
ตัวอย่างเช่น:
OP_0 2b626ed108ad00a944bb2922a309844611d25468 OP_1 2ceefa5fa770ff24f87c5475d76eab519eda6176b11dbe1618fcf755bfac5311 ``` คำเตือน: ข้อผิดพลาดที่อาจเกิดขึ้นที่ควรระวังคือ witness version ที่มีค่า 0 ใช้สำหรับ OP_0 ซึ่งใช้ไบต์ 0x00—แต่เวอร์ชัน witness ที่มีค่า 1 ใช้ OP_1 ซึ่งเป็นไบต์ 0x51 เวอร์ชัน witness 2 ถึง 16 ใช้ไบต์ 0x52 ถึง 0x60 ตามลำดับเมื่อทำการเขียนโค้ดเพื่อเข้ารหัสหรือถอดรหัส bech32m เราขอแนะนำอย่างยิ่งให้คุณใช้เวกเตอร์ทดสอบ (test vectors) ที่มีให้ใน BIP350 เราขอให้คุณตรวจสอบให้แน่ใจว่าโค้ดของคุณผ่านเวกเตอร์ทดสอบที่เกี่ยวข้องกับการจ่ายเงินให้กับเวอร์ชัน segwit ในอนาคตที่ยังไม่ได้รับการกำหนด สิ่งนี้จะช่วยให้ซอฟต์แวร์ของคุณสามารถใช้งานได้อีกหลายปีข้างหน้า แม้ว่าคุณอาจจะไม่สามารถเพิ่มการรองรับคุณสมบัติใหม่ ๆ ของบิตคอยน์ได้ทันทีที่คุณสมบัตินั้น ๆ เริ่มใช้งานได้
Private Key Formats
private key สามารถถูกแสดงได้ในหลาย ๆ รูปแบบที่ต่างกันซึ่งสามารถแปลงเป็นตัวเลขขนาด 256 bit ชุดเดียวกันได้ ดังที่เราจะแสดงให้ดูในตารางข้างล่างนี้ รูปแบบที่แตกต่างกันถูกใช้ในสถานการณ์ที่ต่างกัน รูปแบบเลขฐานสิบหก (Hexadecimal) และรูปแบบไบนารี (raw binary) ถูกใช้ภายในซอฟต์แวร์และแทบจะไม่แสดงให้ผู้ใช้เห็น WIF ถูกใช้สำหรับการนำเข้า/ส่งออกกุญแจระหว่างกระเป๋าเงินและมักใช้ในการแสดงกุญแจส่วนตัวแบบ QR code
รูปแบบของ private key ในปัจจุบัน
ซอฟต์แวร์กระเป๋าเงินบิตคอยน์ในยุคแรกได้สร้าง private key อิสระอย่างน้อยหนึ่งดอกเมื่อกระเป๋าเงินของผู้ใช้ใหม่ถูกเริ่มต้น เมื่อชุดกุญแจเริ่มต้นถูกใช้ทั้งหมดแล้ว กระเป๋าเงินอาจสร้าง private key เพิ่มเติม private key แต่ละดอกสามารถส่งออกหรือนำเข้าได้ ทุกครั้งที่มีการสร้างหรือนำเข้า private key ใหม่ จะต้องมีการสร้างการสำรองข้อมูลกระเป๋าเงินใหม่ด้วย
กระเป๋าเงินบิตคอยน์ในยุคหลังเริ่มใช้กระเป๋าเงินแบบกำหนดได้ (deterministic wallets) ซึ่ง private key ทั้งหมดถูกสร้างจาก seed เพียงค่าเดียว กระเป๋าเงินเหล่านี้จำเป็นต้องสำรองข้อมูลเพียงครั้งเดียวเท่านั้นสำหรับการใช้งานบนเชนทั่วไป แต่อย่างไรก็ตาม หากผู้ใช้ส่งออก private key เพียงดอกเดียวจากกระเป๋าเงินเหล่านี้ และผู้โจมตีได้รับกุญแจนั้นรวมถึงข้อมูลที่ไม่ใช่ข้อมูลส่วนตัวบางอย่างเกี่ยวกับกระเป๋าเงิน พวกเขาอาจสามารถสร้างกุญแจส่วนตัวใด ๆ ในกระเป๋าเงินได้—ทำให้ผู้โจมตีสามารถขโมยเงินทั้งหมดในกระเป๋าเงินได้ นอกจากนี้ ยังไม่สามารถนำเข้ากุญแจสู่กระเป๋าเงินแบบกำหนดได้ นี่หมายความว่าแทบไม่มีกระเป๋าเงินสมัยใหม่ที่รองรับความสามารถในการส่งออกหรือนำเข้ากุญแจเฉพาะดอก ข้อมูลในส่วนนี้มีความสำคัญหลัก ๆ สำหรับผู้ที่ต้องการความเข้ากันได้กับกระเป๋าเงินบิตคอยน์ในยุคแรก ๆ
รูปแบบของ private key (รูปแบบการเข้ารหัส)
private key เดียวกันในแต่ละ format
รูปแบบการแสดงผลทั้งหมดเหล่านี้เป็นวิธีต่างๆ ในการแสดงเลขจำนวนเดียวกัน private key เดียวกัน พวกมันดูแตกต่างกัน แต่รูปแบบใดรูปแบบหนึ่งสามารถแปลงไปเป็นรูปแบบอื่นได้อย่างง่ายดาย
Compressed Private Keys
คำว่า compressed private key ที่ใช้กันทั่วไปนั้นเป็นคำที่เรียกผิด เพราะเมื่อ private key ถูกส่งออกไปในรูปแบบ WIF-compressed มันจะมีความยาวมากกว่า private key แบบ uncompressed 1 Byte (เลข 01 ในช่อง Hex-compressed ในตารางด้านล่างนี้) ซึ่งบ่งบอกว่า private key ตัวนี้ มาจากกระเป๋าเงินรุ่นใหม่และควรใช้เพื่อสร้าง compressed public key เท่านั้น
private key เองไม่ได้ถูกบีบอัดและไม่สามารถบีบอัดได้ คำว่า compressed private key จริงๆ แล้วหมายถึง " private key ซึ่งควรใช้สร้าง compressed public key เท่านั้น" ในขณะที่ uncompressed private key จริงๆ แล้วหมายถึง “private key ซึ่งควรใช้สร้าง uncompressed public key เท่านั้น” คุณควรใช้เพื่ออ้างถึงรูปแบบการส่งออกเป็น "WIF-compressed" หรือ "WIF" เท่านั้น และไม่ควรอ้างถึง private key ว่า "บีบอัด" เพื่อหลีกเลี่ยงความสับสนต่อไป
ตารางนี้แสดงกุญแจเดียวกันที่ถูกเข้ารหัสในรูปแบบ WIF และ WIF-compressed
ตัวอย่าง: กุญแจเดียวกัน แต่รูปแบบต่างกัน
สังเกตว่ารูปแบบ Hex-compressed มีไบต์เพิ่มเติมหนึ่งไบต์ที่ท้าย (01 ในเลขฐานสิบหก) ในขณะที่คำนำหน้าเวอร์ชันการเข้ารหัสแบบ base58 เป็นค่าเดียวกัน (0x80) สำหรับทั้งรูปแบบ WIF และ WIF-compressed การเพิ่มหนึ่งไบต์ที่ท้ายของตัวเลขทำให้อักขระตัวแรกของการเข้ารหัสแบบ base58 เปลี่ยนจาก 5 เป็น K หรือ L
คุณสามารถคิดถึงสิ่งนี้เหมือนกับความแตกต่างของการเข้ารหัสเลขฐานสิบระหว่างตัวเลข 100 และตัวเลข 99 ในขณะที่ 100 มีความยาวมากกว่า 99 หนึ่งหลัก มันยังมีคำนำหน้าเป็น 1 แทนที่จะเป็นคำนำหน้า 9 เมื่อความยาวเปลี่ยนไป มันส่งผลต่อคำนำหน้า ในระบบ base58 คำนำหน้า 5 เปลี่ยนเป็น K หรือ L เมื่อความยาวของตัวเลขเพิ่มขึ้นหนึ่งไบต์
TIPจากหลาม: ผมว่าเขาเขียนย่อหน้านี้ไม่ค่อยรู้เรื่อง แต่ความหมายมันจะประมาณว่า เหมือนถ้าเราต้องการเขียนเลข 100 ในฐาน 10 เราต้องใช้สามตำแหน่ง 100 แต่ถ้าใช้ฐาน 16 เราจะใช้แค่ 2 ตำแหน่งคือ 64 ซึ่งมีค่าเท่ากัน
ถ้ากระเป๋าเงินบิตคอยน์สามารถใช้ compressed public key ได้ มันจะใช้ในทุกธุรกรรม private key ในกระเป๋าเงินจะถูกใช้เพื่อสร้างจุด public key บนเส้นโค้ง ซึ่งจะถูกบีบอัด compressed public key จะถูกใช้เพื่อสร้าง address และ address เหล่านี้จะถูกใช้ในธุรกรรม เมื่อส่งออก private key จากกระเป๋าเงินใหม่ที่ใช้ compressed public key WIF จะถูกปรับเปลี่ยน โดยเพิ่มต่อท้ายขนาด 1 ไบต์ 01 ให้กับ private key ที่ถูกเข้ารหัสแบบ base58check ที่ได้จะเรียกว่า "WIF-compressed" และจะขึ้นต้นด้วยอักษร K หรือ L แทนที่จะขึ้นต้นด้วย "5" เหมือนกับกรณีของคีย์ที่เข้ารหัสแบบ WIF (ไม่บีบอัด) จากกระเป๋าเงินรุ่นเก่า
Advanced Keys and Addresses
ในส่วนต่อไปนี้ เราจะดูรูปแบบของคีย์และ address เช่น vanity addresses และ paper wallets
vanity addresses
vanity addresses หรือ addresses แบบกำหนดเอง คือ address ที่มีข้อความที่มนุษย์อ่านได้และสามารถใช้งานได้จริง ตัวอย่างเช่น 1LoveBPzzD72PUXLzCkYAtGFYmK5vYNR33 อย่างที่เห็นว่ามันเป็น address ที่ถูกต้องซึ่งมีตัวอักษรเป็นคำว่า Love เป็นตัวอักษร base58 สี่ตัวแรก addresses แบบกำหนดเองต้องอาศัยการสร้างและทดสอบ private key หลายพันล้านตัวจนกว่าจะพบ address ที่มีรูปแบบตามที่ต้องการ แม้ว่าจะมีการปรับปรุงบางอย่างในอัลกอริทึมการสร้าง addresses แบบกำหนดเอง แต่กระบวนการนี้ต้องใช้การสุ่มเลือก private key มาสร้าง public key และนำไปสร้าง address และตรวจสอบว่าตรงกับรูปแบบที่ต้องการหรือไม่ โดยทำซ้ำหลายพันล้านครั้งจนกว่าจะพบที่ตรงกัน
เมื่อพบ address ที่ตรงกับรูปแบบที่ต้องการแล้ว private key ที่ใช้สร้าง address นั้นสามารถใช้โดยเจ้าของเพื่อใช้จ่ายบิตคอยน์ได้เหมือนกับ address อื่น ๆ ทุกประการ address ที่กำหนดเองไม่ได้มีความปลอดภัยน้อยกว่าหรือมากกว่าที่ address ๆ พวกมันขึ้นอยู่กับการเข้ารหัสเส้นโค้งรูปวงรี (ECC) และอัลกอริทึมแฮชที่ปลอดภัย (SHA) เหมือนกับ address อื่น ๆ คุณไม่สามารถค้นหา private key ของ address ที่ขึ้นต้นด้วยรูปแบบที่กำหนดเองได้ง่ายกว่า address อื่น ๆ
ตัวอย่างเช่น ยูจีเนียเป็นผู้อำนวยการการกุศลเพื่อเด็กที่ทำงานในฟิลิปปินส์ สมมติว่ายูจีเนียกำลังจัดการระดมทุนและต้องการใช้ address ที่กำหนดเองเพื่อประชาสัมพันธ์การระดมทุน ยูจีเนียจะสร้าง address ที่กำหนดเองที่ขึ้นต้นด้วย "1Kids" เพื่อส่งเสริมการระดมทุนเพื่อการกุศลสำหรับเด็ก มาดูกันว่า address ที่กำหนดเองนี้จะถูกสร้างขึ้นอย่างไรและมีความหมายอย่างไรต่อความปลอดภัยของการกุศลของยูจีเนีย
การสร้าง address ที่กำหนดเอง
ควรเข้าใจว่า address ของบิตคอยน์เป็นเพียงตัวเลขที่แสดงด้วยสัญลักษณ์ในรูปแบบตัวอักษร base58 เท่านั้น เพราะฉะนั้นแล้ว การค้นหารูปแบบเช่น "1Kids" สามารถมองได้ว่าเป็นการค้นหาที่อยู่ในช่วงตั้งแต่ 1Kids11111111111111111111111111111 ถึง 1Kidszzzzzzzzzzzzzzzzzzzzzzzzzzzzz มีประมาณ 5829 (ประมาณ 1.4 × 1051) address ในช่วงนั้น ทั้งหมดขึ้นต้นด้วย "1Kids" ตารางด้านล่างนี้แสดงช่วงของ address ที่มีคำนำหน้า 1Kids
ลองดูรูปแบบ "1Kids" ในรูปของตัวเลขและดูว่าเราอาจพบรูปแบบนี้ใน bitcoin address บ่อยแค่ไหน โดยตารางข้างล่างนี้แสดงให้เห็นถีงคอมพิวเตอร์เดสก์ท็อปทั่วไปที่ไม่มีฮาร์ดแวร์พิเศษสามารถค้นหาคีย์ได้ประมาณ 100,000 คีย์ต่อวินาที
ความถี่ของ address ที่กำหนดเอง (1KidsCharity) และเวลาค้นหาเฉลี่ยบนคอมพิวเตอร์เดสก์ท็อป
ดังที่เห็นได้ ยูจีเนียคงไม่สามารถสร้าง address แบบกำหนดเอง "1KidsCharity" ได้ในเร็ว ๆ นี้ แม้ว่าเธอจะมีคอมพิวเตอร์หลายพันเครื่องก็ตาม ทุกตัวอักษรที่เพิ่มขึ้นจะเพิ่มความยากขึ้น 58 เท่า รูปแบบที่มีมากกว่า 7 ตัวอักษรมักจะถูกค้นพบโดยฮาร์ดแวร์พิเศษ เช่น คอมพิวเตอร์เดสก์ท็อปที่สร้างขึ้นเป็นพิเศษที่มีหน่วยประมวลผลกราฟิก (GPUs) หลายตัว การค้นหา address แบบกำหนดเองบนระบบ GPU เร็วกว่าบน CPU ทั่วไปหลายเท่า
อีกวิธีหนึ่งในการหา address แบบกำหนดเองคือการจ้างงานไปยังกลุ่มคนขุด vanity addresses กลุ่มคนขุดvanity addresses เป็นบริการที่ให้ผู้ที่มีฮาร์ดแวร์ที่เร็วได้รับบิตคอยน์จากการค้นหา vanity addresses ให้กับผู้อื่น ยูจีเนียสามารถจ่ายค่าธรรมเนียมเพื่อจ้างงานการค้นหา vanity addresses ที่มีรูปแบบ 7 ตัวอักษรและได้ผลลัพธ์ในเวลาเพียงไม่กี่ชั่วโมงแทนที่จะต้องใช้ CPU ค้นหาเป็นเดือน ๆ
การสร้างที่ address แบบกำหนดเองเป็นการใช้วิธีการแบบ brute-force (ลองทุกความเป็นไปได้): ลองใช้คีย์สุ่ม ตรวจสอบ address ที่ได้ว่าตรงกับรูปแบบที่ต้องการหรือไม่ และทำซ้ำจนกว่าจะสำเร็จ
ความปลอดภัยและความเป็นส่วนตัวของ address แบบกำหนดเอง
address แบบกำหนดเองเคยเป็นที่นิยมในช่วงแรก ๆ ของบิตคอยน์ แต่แทบจะหายไปจากการใช้งานทั้งหมดในปี 2023 มีสาเหตุที่น่าจะเป็นไปได้สองประการสำหรับแนวโน้มนี้: - Deterministic wallets: ดังที่เราเห็นในพาร์ทของการกู้คืน การที่จะสำรองคีย์ทุกตัวในกระเป๋าเงินสมัยใหม่ส่วนใหญ่นั้น ทำเพียงแค่จดคำหรือตัวอักษรไม่กี่ตัว ซึ่งนี่เป็นผลจากการสร้างคีย์ทุกตัวในกระเป๋าเงินจากคำหรือตัวอักษรเหล่านั้นโดยใช้อัลกอริทึมแบบกำหนดได้ จึงไม่สามารถใช้ address แบบกำหนดเองกับ Deterministic wallets ได้ เว้นแต่ผู้ใช้จะสำรองข้อมูลเพิ่มเติมสำหรับ address แบบกำหนดเองทุก address ที่พวกเขาสร้าง ในทางปฏิบัติแล้วกระเป๋าเงินส่วนใหญ่ที่ใช้การสร้างคีย์แบบกำหนดได้ โดยไม่อนุญาตให้นำเข้าคีย์ส่วนตัวหรือการปรับแต่งคีย์จากโปรแกรมสร้าง address ที่กำหนดเอง
- การหลีกเลี่ยงการใช้ address ซ้ำซ้อน: การใช้ address แบบกำหนดเองเพื่อรับการชำระเงินหลายครั้งไปยัง address เดียวกันจะสร้างความเชื่อมโยงระหว่างการชำระเงินทั้งหมดเหล่านั้น นี่อาจเป็นที่ยอมรับได้สำหรับยูจีเนียหากองค์กรไม่แสวงหาผลกำไรของเธอจำเป็นต้องรายงานรายได้และค่าใช้จ่ายต่อหน่วยงานภาษีอยู่แล้ว แต่อย่างไรก็ตาม มันยังลดความเป็นส่วนตัวของคนที่จ่ายเงินให้ยูจีเนียหรือรับเงินจากเธอด้วย ตัวอย่างเช่น อลิซอาจต้องการบริจาคโดยไม่เปิดเผยตัวตน และบ็อบอาจไม่ต้องการให้ลูกค้ารายอื่นของเขารู้ว่าเขาให้ราคาส่วนลดแก่ยูจีเนีย
เราไม่คาดว่าจะเห็น address แบบกำหนดเองมากนักในอนาคต เว้นแต่ปัญหาที่กล่าวมาก่อนหน้านี้จะได้รับการแก้ไข
Paper Wallets
paper wallet หรือก็คือ private key ที่พิมพ์ลงในกระดาษ และโดยทั่วไปแล้วมักจะมีข้อมูลของ public key หรือ address บนกระดาษนั้นด้วยแม้ว่าจริง ๆ แล้วมันจะสามารถคำนวณได้ด้วย private key ก็ตาม
คำเตือน: paper wallet เป็นเทคโนโลยีที่ล้าสมัยแล้วและอันตรายสำหรับผู้ใช้ส่วนใหญ่ เพราะเป็นเรื่องยากที่จะสร้างมันอย่างปลอดภัย โดยเฉพาะอย่างยิ่งความเป็นไปได้ที่โค้ดที่ใช้สร้างอาจถูกแทรกแซงด้วยผู้ไม่ประสงค์ดี และอาจจะทำให้ผู้ใช้โดนขโมยบิตคอยน์ทั้งหมดไปได้ paper wallet ถูกแสดงที่นี่เพื่อวัตถุประสงค์ในการให้ข้อมูลเท่านั้นและไม่ควรใช้สำหรับเก็บบิตคอยน์
paper wallet ได้ถูกออกแบบมาเพื่อเป็นของขวัญและมีธีมตามฤดูกาล เช่น คริสต์มาสและปีใหม่ ส่วนเหตุผลอื่น ๆ ถูกออกแบบเพื่อการเก็บรักษาในตู้นิรภัยของธนาคารหรือตู้เซฟโดยมี private key ถูกซ่อนไว้ในบางวิธี ไม่ว่าจะด้วยสติกเกอร์แบบขูดที่ทึบแสงหรือพับและปิดผนึกด้วยแผ่นฟอยล์กันการงัดแงะ ส่วนการออกแบบอื่น ๆ มีสำเนาเพิ่มเติมของคีย์และ address ในรูปแบบของตอนฉีกที่แยกออกได้คล้ายกับตั๋ว ช่วยให้คุณสามารถเก็บสำเนาหลายชุดเพื่อป้องกันจากไฟไหม้ น้ำท่วม หรือภัยพิบัติทางธรรมชาติอื่น ๆ
จากการออกแบบเดิมของบิตคอยน์ที่เน้น public key ไปจนถึง address และสคริปต์สมัยใหม่อย่าง bech32m และ pay to taproot—และแม้แต่การอัพเกรดบิตคอยน์ในอนาคต—คุณได้เรียนรู้วิธีที่โปรโตคอลบิตคอยน์อนุญาตให้ผู้จ่ายเงินระบุกระเป๋าเงินที่ควรได้รับการชำระเงินของพวกเขา แต่เมื่อเป็นกระเป๋าเงินของคุณเองที่รับการชำระเงิน คุณจะต้องการความมั่นใจว่าคุณจะยังคงเข้าถึงเงินนั้นได้แม้ว่าจะเกิดอะไรขึ้นกับข้อมูลกระเป๋าเงินของคุณ ในบทต่อไป เราจะดูว่ากระเป๋าเงินบิตคอยน์ถูกออกแบบอย่างไรเพื่อปกป้องเงินทุนจากภัยคุกคามหลากหลายรูปแบบ

2025-03-22 00:22:40Vi recentemente um post onde a pessoa diz que aquele final do filme O Doutrinador (2019) não faz sentido porque mesmo o protagonista explodindo o Palácio dos Três Poderes, não acaba com a corrupção no Brasil.
Progressistas não sabem ler e não conseguem interpretar textos corretamente. O final de Doutrinador não tem a ver com isso, tem a ver com a relação entre o Herói e a sua Cidade.
Nas histórias em quadrinhos há uma ligação entre a cidade e o Super-Herói. Gotham City por exemplo, cria o Batman. Isso é mostrado em The Batman (2022) e em Batman: Cavaleiro das Trevas, quando aquele garoto no final, diz para o Batman não fugir, porque ele queria ver o Batman de novo. E o Comissário Gordon diz que o "Batman é o que a cidade de Gotham precisa."
Batman: Cavaleiro das Trevas Ressurge mostra a cidade de Gotham sendo tomada pela corrupção e pela ideologia do Bane. A Cidade vai definhando em imoralidade e o Bruce, ao olhar da prisão a cidade sendo destruída, decide que o Batman precisa voltar porque se Gotham for destruída, o Batman é destruído junto. E isso o da forças para consegue fugir daquele poço e voltar para salvar Gotham.
Isso também é mostrado em Demolidor. Na série Demolidor o Matt Murdock sempre fala que precisa defender a cidade Cozinha do Inferno; que o Fisk não vai dominar a cidade e fazer o que ele quiser nela. Inclusive na terceira temporada isso fica mais evidente na luta final na mansão do Fisk, onde Matt grita que agora a cidade toda vai saber o que ele fez; a cidade vai ver o mal que ele é para Hell's Kitchen, porque a gente sabe que o Fisk fez de tudo para a imagem do Demolidor entrar e descrédito perante os cidadãos, então o que acontece no final do filme O Doutrinador não significa que ele está acabando com a corrupção quando explode o Congresso, ele está praticamente interrompendo o ciclo do sistema, colocando uma falha em sua engrenagem.
Quando você ouve falar de Brasília, você pensa na corrupção dos políticos, onde a farra acontece,, onde corruptos desviam dinheiro arrecadado dos impostos, impostos estes que são centralizados na União. Então quando você ouve falarem de Brasília, sempre pensa que o pessoal que mora lá, mora junto com tudo de podre que acontece no Brasil.
Logo quando o Doutrinador explode tudo ali, ele está basicamente destruindo o mecanismo que suja Brasília. Ele está fazendo isso naquela cidade. Porque o símbolo da cidade é justamente esse, a farsa de que naquele lugar o povo será ouvido e a justiça será feita. Ele está destruindo a ideologia de que o Estado nos protege, nos dá segurança, saúde e educação. Porque na verdade o Estado só existe para privilegiar os políticos, funcionários públicos de auto escalão, suas famílias e amigos. Enquanto que o povo sofre para sustentar a elite política. O protagonista Miguel entendeu isso quando a filha dele morreu na fila do SUS.

2025-05-16 18:06:46Bitcoin has always been rooted in freedom and resistance to authority. I get that many of you are conflicted about the US Government stacking but by design we cannot stop anyone from using bitcoin. Many have asked me for my thoughts on the matter, so let’s rip it.
Concern
One of the most glaring issues with the strategic bitcoin reserve is its foundation, built on stolen bitcoin. For those of us who value private property this is an obvious betrayal of our core principles. Rather than proof of work, the bitcoin that seeds this reserve has been taken by force. The US Government should return the bitcoin stolen from Bitfinex and the Silk Road.
Using stolen bitcoin for the reserve creates a perverse incentive. If governments see bitcoin as a valuable asset, they will ramp up efforts to confiscate more bitcoin. The precedent is a major concern, and I stand strongly against it, but it should be also noted that governments were already seizing coin before the reserve so this is not really a change in policy.
Ideally all seized bitcoin should be burned, by law. This would align incentives properly and make it less likely for the government to actively increase coin seizures. Due to the truly scarce properties of bitcoin, all burned bitcoin helps existing holders through increased purchasing power regardless. This change would be unlikely but those of us in policy circles should push for it regardless. It would be best case scenario for American bitcoiners and would create a strong foundation for the next century of American leadership.
Optimism
The entire point of bitcoin is that we can spend or save it without permission. That said, it is a massive benefit to not have one of the strongest governments in human history actively trying to ruin our lives.
Since the beginning, bitcoiners have faced horrible regulatory trends. KYC, surveillance, and legal cases have made using bitcoin and building bitcoin businesses incredibly difficult. It is incredibly important to note that over the past year that trend has reversed for the first time in a decade. A strategic bitcoin reserve is a key driver of this shift. By holding bitcoin, the strongest government in the world has signaled that it is not just a fringe technology but rather truly valuable, legitimate, and worth stacking.
This alignment of incentives changes everything. The US Government stacking proves bitcoin’s worth. The resulting purchasing power appreciation helps all of us who are holding coin and as bitcoin succeeds our government receives direct benefit. A beautiful positive feedback loop.
Realism
We are trending in the right direction. A strategic bitcoin reserve is a sign that the state sees bitcoin as an asset worth embracing rather than destroying. That said, there is a lot of work left to be done. We cannot be lulled into complacency, the time to push forward is now, and we cannot take our foot off the gas. We have a seat at the table for the first time ever. Let's make it worth it.
We must protect the right to free usage of bitcoin and other digital technologies. Freedom in the digital age must be taken and defended, through both technical and political avenues. Multiple privacy focused developers are facing long jail sentences for building tools that protect our freedom. These cases are not just legal battles. They are attacks on the soul of bitcoin. We need to rally behind them, fight for their freedom, and ensure the ethos of bitcoin survives this new era of government interest. The strategic reserve is a step in the right direction, but it is up to us to hold the line and shape the future.

2025-05-16 17:59:23Recently we have seen a wave of high profile X accounts hacked. These attacks have exposed the fragility of the status quo security model used by modern social media platforms like X. Many users have asked if nostr fixes this, so lets dive in. How do these types of attacks translate into the world of nostr apps? For clarity, I will use X’s security model as representative of most big tech social platforms and compare it to nostr.
The Status Quo
On X, you never have full control of your account. Ultimately to use it requires permission from the company. They can suspend your account or limit your distribution. Theoretically they can even post from your account at will. An X account is tied to an email and password. Users can also opt into two factor authentication, which adds an extra layer of protection, a login code generated by an app. In theory, this setup works well, but it places a heavy burden on users. You need to create a strong, unique password and safeguard it. You also need to ensure your email account and phone number remain secure, as attackers can exploit these to reset your credentials and take over your account. Even if you do everything responsibly, there is another weak link in X infrastructure itself. The platform’s infrastructure allows accounts to be reset through its backend. This could happen maliciously by an employee or through an external attacker who compromises X’s backend. When an account is compromised, the legitimate user often gets locked out, unable to post or regain control without contacting X’s support team. That process can be slow, frustrating, and sometimes fruitless if support denies the request or cannot verify your identity. Often times support will require users to provide identification info in order to regain access, which represents a privacy risk. The centralized nature of X means you are ultimately at the mercy of the company’s systems and staff.
Nostr Requires Responsibility
Nostr flips this model radically. Users do not need permission from a company to access their account, they can generate as many accounts as they want, and cannot be easily censored. The key tradeoff here is that users have to take complete responsibility for their security. Instead of relying on a username, password, and corporate servers, nostr uses a private key as the sole credential for your account. Users generate this key and it is their responsibility to keep it safe. As long as you have your key, you can post. If someone else gets it, they can post too. It is that simple. This design has strong implications. Unlike X, there is no backend reset option. If your key is compromised or lost, there is no customer support to call. In a compromise scenario, both you and the attacker can post from the account simultaneously. Neither can lock the other out, since nostr relays simply accept whatever is signed with a valid key.
The benefit? No reliance on proprietary corporate infrastructure.. The negative? Security rests entirely on how well you protect your key.
Future Nostr Security Improvements
For many users, nostr’s standard security model, storing a private key on a phone with an encrypted cloud backup, will likely be sufficient. It is simple and reasonably secure. That said, nostr’s strength lies in its flexibility as an open protocol. Users will be able to choose between a range of security models, balancing convenience and protection based on need.
One promising option is a web of trust model for key rotation. Imagine pre-selecting a group of trusted friends. If your account is compromised, these people could collectively sign an event announcing the compromise to the network and designate a new key as your legitimate one. Apps could handle this process seamlessly in the background, notifying followers of the switch without much user interaction. This could become a popular choice for average users, but it is not without tradeoffs. It requires trust in your chosen web of trust, which might not suit power users or large organizations. It also has the issue that some apps may not recognize the key rotation properly and followers might get confused about which account is “real.”
For those needing higher security, there is the option of multisig using FROST (Flexible Round-Optimized Schnorr Threshold). In this setup, multiple keys must sign off on every action, including posting and updating a profile. A hacker with just one key could not do anything. This is likely overkill for most users due to complexity and inconvenience, but it could be a game changer for large organizations, companies, and governments. Imagine the White House nostr account requiring signatures from multiple people before a post goes live, that would be much more secure than the status quo big tech model.
Another option are hardware signers, similar to bitcoin hardware wallets. Private keys are kept on secure, offline devices, separate from the internet connected phone or computer you use to broadcast events. This drastically reduces the risk of remote hacks, as private keys never touches the internet. It can be used in combination with multisig setups for extra protection. This setup is much less convenient and probably overkill for most but could be ideal for governments, companies, or other high profile accounts.
Nostr’s security model is not perfect but is robust and versatile. Ultimately users are in control and security is their responsibility. Apps will give users multiple options to choose from and users will choose what best fits their need.

2025-03-18 14:43:08Warning: This piece contains a conversation about difficult topics. Please proceed with caution.
TL;DR please educate your children about online safety.
Julian Assange wrote in his 2012 book Cypherpunks, “This book is not a manifesto. There isn’t time for that. This book is a warning.” I read it a few times over the past summer. Those opening lines definitely stood out to me. I wish we had listened back then. He saw something about the internet that few had the ability to see. There are some individuals who are so close to a topic that when they speak, it’s difficult for others who aren’t steeped in it to visualize what they’re talking about. I didn’t read the book until more recently. If I had read it when it came out, it probably would have sounded like an unknown foreign language to me. Today it makes more sense.
This isn’t a manifesto. This isn’t a book. There is no time for that. It’s a warning and a possible solution from a desperate and determined survivor advocate who has been pulling and unraveling a thread for a few years. At times, I feel too close to this topic to make any sense trying to convey my pathway to my conclusions or thoughts to the general public. My hope is that if nothing else, I can convey my sense of urgency while writing this. This piece is a watchman’s warning.
When a child steps online, they are walking into a new world. A new reality. When you hand a child the internet, you are handing them possibilities—good, bad, and ugly. This is a conversation about lowering the potential of negative outcomes of stepping into that new world and how I came to these conclusions. I constantly compare the internet to the road. You wouldn’t let a young child run out into the road with no guidance or safety precautions. When you hand a child the internet without any type of guidance or safety measures, you are allowing them to play in rush hour, oncoming traffic. “Look left, look right for cars before crossing.” We almost all have been taught that as children. What are we taught as humans about safety before stepping into a completely different reality like the internet? Very little.
I could never really figure out why many folks in tech, privacy rights activists, and hackers seemed so cold to me while talking about online child sexual exploitation. I always figured that as a survivor advocate for those affected by these crimes, that specific, skilled group of individuals would be very welcoming and easy to talk to about such serious topics. I actually had one hacker laugh in my face when I brought it up while I was looking for answers. I thought maybe this individual thought I was accusing them of something I wasn’t, so I felt bad for asking. I was constantly extremely disappointed and would ask myself, “Why don’t they care? What could I say to make them care more? What could I say to make them understand the crisis and the level of suffering that happens as a result of the problem?”
I have been serving minor survivors of online child sexual exploitation for years. My first case serving a survivor of this specific crime was in 2018—a 13-year-old girl sexually exploited by a serial predator on Snapchat. That was my first glimpse into this side of the internet. I won a national award for serving the minor survivors of Twitter in 2023, but I had been working on that specific project for a few years. I was nominated by a lawyer representing two survivors in a legal battle against the platform. I’ve never really spoken about this before, but at the time it was a choice for me between fighting Snapchat or Twitter. I chose Twitter—or rather, Twitter chose me. I heard about the story of John Doe #1 and John Doe #2, and I was so unbelievably broken over it that I went to war for multiple years. I was and still am royally pissed about that case. As far as I was concerned, the John Doe #1 case proved that whatever was going on with corporate tech social media was so out of control that I didn’t have time to wait, so I got to work. It was reading the messages that John Doe #1 sent to Twitter begging them to remove his sexual exploitation that broke me. He was a child begging adults to do something. A passion for justice and protecting kids makes you do wild things. I was desperate to find answers about what happened and searched for solutions. In the end, the platform Twitter was purchased. During the acquisition, I just asked Mr. Musk nicely to prioritize the issue of detection and removal of child sexual exploitation without violating digital privacy rights or eroding end-to-end encryption. Elon thanked me multiple times during the acquisition, made some changes, and I was thanked by others on the survivors’ side as well.
I still feel that even with the progress made, I really just scratched the surface with Twitter, now X. I left that passion project when I did for a few reasons. I wanted to give new leadership time to tackle the issue. Elon Musk made big promises that I knew would take a while to fulfill, but mostly I had been watching global legislation transpire around the issue, and frankly, the governments are willing to go much further with X and the rest of corporate tech than I ever would. My work begging Twitter to make changes with easier reporting of content, detection, and removal of child sexual exploitation material—without violating privacy rights or eroding end-to-end encryption—and advocating for the minor survivors of the platform went as far as my principles would have allowed. I’m grateful for that experience. I was still left with a nagging question: “How did things get so bad with Twitter where the John Doe #1 and John Doe #2 case was able to happen in the first place?” I decided to keep looking for answers. I decided to keep pulling the thread.
I never worked for Twitter. This is often confusing for folks. I will say that despite being disappointed in the platform’s leadership at times, I loved Twitter. I saw and still see its value. I definitely love the survivors of the platform, but I also loved the platform. I was a champion of the platform’s ability to give folks from virtually around the globe an opportunity to speak and be heard.
I want to be clear that John Doe #1 really is my why. He is the inspiration. I am writing this because of him. He represents so many globally, and I’m still inspired by his bravery. One child’s voice begging adults to do something—I’m an adult, I heard him. I’d go to war a thousand more lifetimes for that young man, and I don’t even know his name. Fighting has been personally dark at times; I’m not even going to try to sugarcoat it, but it has been worth it.
The data surrounding the very real crime of online child sexual exploitation is available to the public online at any time for anyone to see. I’d encourage you to go look at the data for yourself. I believe in encouraging folks to check multiple sources so that you understand the full picture. If you are uncomfortable just searching around the internet for information about this topic, use the terms “CSAM,” “CSEM,” “SG-CSEM,” or “AI Generated CSAM.” The numbers don’t lie—it’s a nightmare that’s out of control. It’s a big business. The demand is high, and unfortunately, business is booming. Organizations collect the data, tech companies often post their data, governments report frequently, and the corporate press has covered a decent portion of the conversation, so I’m sure you can find a source that you trust.
Technology is changing rapidly, which is great for innovation as a whole but horrible for the crime of online child sexual exploitation. Those wishing to exploit the vulnerable seem to be adapting to each technological change with ease. The governments are so far behind with tackling these issues that as I’m typing this, it’s borderline irrelevant to even include them while speaking about the crime or potential solutions. Technology is changing too rapidly, and their old, broken systems can’t even dare to keep up. Think of it like the governments’ “War on Drugs.” Drugs won. In this case as well, the governments are not winning. The governments are talking about maybe having a meeting on potentially maybe having legislation around the crimes. The time to have that meeting would have been many years ago. I’m not advocating for governments to legislate our way out of this. I’m on the side of educating and innovating our way out of this.
I have been clear while advocating for the minor survivors of corporate tech platforms that I would not advocate for any solution to the crime that would violate digital privacy rights or erode end-to-end encryption. That has been a personal moral position that I was unwilling to budge on. This is an extremely unpopular and borderline nonexistent position in the anti-human trafficking movement and online child protection space. I’m often fearful that I’m wrong about this. I have always thought that a better pathway forward would have been to incentivize innovation for detection and removal of content. I had no previous exposure to privacy rights activists or Cypherpunks—actually, I came to that conclusion by listening to the voices of MENA region political dissidents and human rights activists. After developing relationships with human rights activists from around the globe, I realized how important privacy rights and encryption are for those who need it most globally. I was simply unwilling to give more power, control, and opportunities for mass surveillance to big abusers like governments wishing to enslave entire nations and untrustworthy corporate tech companies to potentially end some portion of abuses online. On top of all of it, it has been clear to me for years that all potential solutions outside of violating digital privacy rights to detect and remove child sexual exploitation online have not yet been explored aggressively. I’ve been disappointed that there hasn’t been more of a conversation around preventing the crime from happening in the first place.
What has been tried is mass surveillance. In China, they are currently under mass surveillance both online and offline, and their behaviors are attached to a social credit score. Unfortunately, even on state-run and controlled social media platforms, they still have child sexual exploitation and abuse imagery pop up along with other crimes and human rights violations. They also have a thriving black market online due to the oppression from the state. In other words, even an entire loss of freedom and privacy cannot end the sexual exploitation of children online. It’s been tried. There is no reason to repeat this method.
It took me an embarrassingly long time to figure out why I always felt a slight coldness from those in tech and privacy-minded individuals about the topic of child sexual exploitation online. I didn’t have any clue about the “Four Horsemen of the Infocalypse.” This is a term coined by Timothy C. May in 1988. I would have been a child myself when he first said it. I actually laughed at myself when I heard the phrase for the first time. I finally got it. The Cypherpunks weren’t wrong about that topic. They were so spot on that it is borderline uncomfortable. I was mad at first that they knew that early during the birth of the internet that this issue would arise and didn’t address it. Then I got over it because I realized that it wasn’t their job. Their job was—is—to write code. Their job wasn’t to be involved and loving parents or survivor advocates. Their job wasn’t to educate children on internet safety or raise awareness; their job was to write code.
They knew that child sexual abuse material would be shared on the internet. They said what would happen—not in a gleeful way, but a prediction. Then it happened.
I equate it now to a concrete company laying down a road. As you’re pouring the concrete, you can say to yourself, “A terrorist might travel down this road to go kill many, and on the flip side, a beautiful child can be born in an ambulance on this road.” Who or what travels down the road is not their responsibility—they are just supposed to lay the concrete. I’d never go to a concrete pourer and ask them to solve terrorism that travels down roads. Under the current system, law enforcement should stop terrorists before they even make it to the road. The solution to this specific problem is not to treat everyone on the road like a terrorist or to not build the road.
So I understand the perceived coldness from those in tech. Not only was it not their job, but bringing up the topic was seen as the equivalent of asking a free person if they wanted to discuss one of the four topics—child abusers, terrorists, drug dealers, intellectual property pirates, etc.—that would usher in digital authoritarianism for all who are online globally.
Privacy rights advocates and groups have put up a good fight. They stood by their principles. Unfortunately, when it comes to corporate tech, I believe that the issue of privacy is almost a complete lost cause at this point. It’s still worth pushing back, but ultimately, it is a losing battle—a ticking time bomb.
I do think that corporate tech providers could have slowed down the inevitable loss of privacy at the hands of the state by prioritizing the detection and removal of CSAM when they all started online. I believe it would have bought some time, fewer would have been traumatized by that specific crime, and I do believe that it could have slowed down the demand for content. If I think too much about that, I’ll go insane, so I try to push the “if maybes” aside, but never knowing if it could have been handled differently will forever haunt me. At night when it’s quiet, I wonder what I would have done differently if given the opportunity. I’ll probably never know how much corporate tech knew and ignored in the hopes that it would go away while the problem continued to get worse. They had different priorities. The most voiceless and vulnerable exploited on corporate tech never had much of a voice, so corporate tech providers didn’t receive very much pushback.
Now I’m about to say something really wild, and you can call me whatever you want to call me, but I’m going to say what I believe to be true. I believe that the governments are either so incompetent that they allowed the proliferation of CSAM online, or they knowingly allowed the problem to fester long enough to have an excuse to violate privacy rights and erode end-to-end encryption. The US government could have seized the corporate tech providers over CSAM, but I believe that they were so useful as a propaganda arm for the regimes that they allowed them to continue virtually unscathed.
That season is done now, and the governments are making the issue a priority. It will come at a high cost. Privacy on corporate tech providers is virtually done as I’m typing this. It feels like a death rattle. I’m not particularly sure that we had much digital privacy to begin with, but the illusion of a veil of privacy feels gone.
To make matters slightly more complex, it would be hard to convince me that once AI really gets going, digital privacy will exist at all.
I believe that there should be a conversation shift to preserving freedoms and human rights in a post-privacy society.
I don’t want to get locked up because AI predicted a nasty post online from me about the government. I’m not a doomer about AI—I’m just going to roll with it personally. I’m looking forward to the positive changes that will be brought forth by AI. I see it as inevitable. A bit of privacy was helpful while it lasted. Please keep fighting to preserve what is left of privacy either way because I could be wrong about all of this.
On the topic of AI, the addition of AI to the horrific crime of child sexual abuse material and child sexual exploitation in multiple ways so far has been devastating. It’s currently out of control. The genie is out of the bottle. I am hopeful that innovation will get us humans out of this, but I’m not sure how or how long it will take. We must be extremely cautious around AI legislation. It should not be illegal to innovate even if some bad comes with the good. I don’t trust that the governments are equipped to decide the best pathway forward for AI. Source: the entire history of the government.
I have been personally negatively impacted by AI-generated content. Every few days, I get another alert that I’m featured again in what’s called “deep fake pornography” without my consent. I’m not happy about it, but what pains me the most is the thought that for a period of time down the road, many globally will experience what myself and others are experiencing now by being digitally sexually abused in this way. If you have ever had your picture taken and posted online, you are also at risk of being exploited in this way. Your child’s image can be used as well, unfortunately, and this is just the beginning of this particular nightmare. It will move to more realistic interpretations of sexual behaviors as technology improves. I have no brave words of wisdom about how to deal with that emotionally. I do have hope that innovation will save the day around this specific issue. I’m nervous that everyone online will have to ID verify due to this issue. I see that as one possible outcome that could help to prevent one problem but inadvertently cause more problems, especially for those living under authoritarian regimes or anyone who needs to remain anonymous online. A zero-knowledge proof (ZKP) would probably be the best solution to these issues. There are some survivors of violence and/or sexual trauma who need to remain anonymous online for various reasons. There are survivor stories available online of those who have been abused in this way. I’d encourage you seek out and listen to their stories.
There have been periods of time recently where I hesitate to say anything at all because more than likely AI will cover most of my concerns about education, awareness, prevention, detection, and removal of child sexual exploitation online, etc.
Unfortunately, some of the most pressing issues we’ve seen online over the last few years come in the form of “sextortion.” Self-generated child sexual exploitation (SG-CSEM) numbers are continuing to be terrifying. I’d strongly encourage that you look into sextortion data. AI + sextortion is also a huge concern. The perpetrators are using the non-sexually explicit images of children and putting their likeness on AI-generated child sexual exploitation content and extorting money, more imagery, or both from minors online. It’s like a million nightmares wrapped into one. The wild part is that these issues will only get more pervasive because technology is harnessed to perpetuate horror at a scale unimaginable to a human mind.
Even if you banned phones and the internet or tried to prevent children from accessing the internet, it wouldn’t solve it. Child sexual exploitation will still be with us until as a society we start to prevent the crime before it happens. That is the only human way out right now.
There is no reset button on the internet, but if I could go back, I’d tell survivor advocates to heed the warnings of the early internet builders and to start education and awareness campaigns designed to prevent as much online child sexual exploitation as possible. The internet and technology moved quickly, and I don’t believe that society ever really caught up. We live in a world where a child can be groomed by a predator in their own home while sitting on a couch next to their parents watching TV. We weren’t ready as a species to tackle the fast-paced algorithms and dangers online. It happened too quickly for parents to catch up. How can you parent for the ever-changing digital world unless you are constantly aware of the dangers?
I don’t think that the internet is inherently bad. I believe that it can be a powerful tool for freedom and resistance. I’ve spoken a lot about the bad online, but there is beauty as well. We often discuss how victims and survivors are abused online; we rarely discuss the fact that countless survivors around the globe have been able to share their experiences, strength, hope, as well as provide resources to the vulnerable. I do question if giving any government or tech company access to censorship, surveillance, etc., online in the name of serving survivors might not actually impact a portion of survivors negatively. There are a fair amount of survivors with powerful abusers protected by governments and the corporate press. If a survivor cannot speak to the press about their abuse, the only place they can go is online, directly or indirectly through an independent journalist who also risks being censored. This scenario isn’t hard to imagine—it already happened in China. During #MeToo, a survivor in China wanted to post their story. The government censored the post, so the survivor put their story on the blockchain. I’m excited that the survivor was creative and brave, but it’s terrifying to think that we live in a world where that situation is a necessity.
I believe that the future for many survivors sharing their stories globally will be on completely censorship-resistant and decentralized protocols. This thought in particular gives me hope. When we listen to the experiences of a diverse group of survivors, we can start to understand potential solutions to preventing the crimes from happening in the first place.
My heart is broken over the gut-wrenching stories of survivors sexually exploited online. Every time I hear the story of a survivor, I do think to myself quietly, “What could have prevented this from happening in the first place?” My heart is with survivors.
My head, on the other hand, is full of the understanding that the internet should remain free. The free flow of information should not be stopped. My mind is with the innocent citizens around the globe that deserve freedom both online and offline.
The problem is that governments don’t only want to censor illegal content that violates human rights—they create legislation that is so broad that it can impact speech and privacy of all. “Don’t you care about the kids?” Yes, I do. I do so much that I’m invested in finding solutions. I also care about all citizens around the globe that deserve an opportunity to live free from a mass surveillance society. If terrorism happens online, I should not be punished by losing my freedom. If drugs are sold online, I should not be punished. I’m not an abuser, I’m not a terrorist, and I don’t engage in illegal behaviors. I refuse to lose freedom because of others’ bad behaviors online.
I want to be clear that on a long enough timeline, the governments will decide that they can be better parents/caregivers than you can if something isn’t done to stop minors from being sexually exploited online. The price will be a complete loss of anonymity, privacy, free speech, and freedom of religion online. I find it rather insulting that governments think they’re better equipped to raise children than parents and caretakers.
So we can’t go backwards—all that we can do is go forward. Those who want to have freedom will find technology to facilitate their liberation. This will lead many over time to decentralized and open protocols. So as far as I’m concerned, this does solve a few of my worries—those who need, want, and deserve to speak freely online will have the opportunity in most countries—but what about online child sexual exploitation?
When I popped up around the decentralized space, I was met with the fear of censorship. I’m not here to censor you. I don’t write code. I couldn’t censor anyone or any piece of content even if I wanted to across the internet, no matter how depraved. I don’t have the skills to do that.
I’m here to start a conversation. Freedom comes at a cost. You must always fight for and protect your freedom. I can’t speak about protecting yourself from all of the Four Horsemen because I simply don’t know the topics well enough, but I can speak about this one topic.
If there was a shortcut to ending online child sexual exploitation, I would have found it by now. There isn’t one right now. I believe that education is the only pathway forward to preventing the crime of online child sexual exploitation for future generations.
I propose a yearly education course for every child of all school ages, taught as a standard part of the curriculum. Ideally, parents/caregivers would be involved in the education/learning process.
Course: - The creation of the internet and computers - The fight for cryptography - The tech supply chain from the ground up (example: human rights violations in the supply chain) - Corporate tech - Freedom tech - Data privacy - Digital privacy rights - AI (history-current) - Online safety (predators, scams, catfishing, extortion) - Bitcoin - Laws - How to deal with online hate and harassment - Information on who to contact if you are being abused online or offline - Algorithms - How to seek out the truth about news, etc., online
The parents/caregivers, homeschoolers, unschoolers, and those working to create decentralized parallel societies have been an inspiration while writing this, but my hope is that all children would learn this course, even in government ran schools. Ideally, parents would teach this to their own children.
The decentralized space doesn’t want child sexual exploitation to thrive. Here’s the deal: there has to be a strong prevention effort in order to protect the next generation. The internet isn’t going anywhere, predators aren’t going anywhere, and I’m not down to let anyone have the opportunity to prove that there is a need for more government. I don’t believe that the government should act as parents. The governments have had a chance to attempt to stop online child sexual exploitation, and they didn’t do it. Can we try a different pathway forward?
I’d like to put myself out of a job. I don’t want to ever hear another story like John Doe #1 ever again. This will require work. I’ve often called online child sexual exploitation the lynchpin for the internet. It’s time to arm generations of children with knowledge and tools. I can’t do this alone.
Individuals have fought so that I could have freedom online. I want to fight to protect it. I don’t want child predators to give the government any opportunity to take away freedom. Decentralized spaces are as close to a reset as we’ll get with the opportunity to do it right from the start. Start the youth off correctly by preventing potential hazards to the best of your ability.
The good news is anyone can work on this! I’d encourage you to take it and run with it. I added the additional education about the history of the internet to make the course more educational and fun. Instead of cleaning up generations of destroyed lives due to online sexual exploitation, perhaps this could inspire generations of those who will build our futures. Perhaps if the youth is armed with knowledge, they can create more tools to prevent the crime.
This one solution that I’m suggesting can be done on an individual level or on a larger scale. It should be adjusted depending on age, learning style, etc. It should be fun and playful.
This solution does not address abuse in the home or some of the root causes of offline child sexual exploitation. My hope is that it could lead to some survivors experiencing abuse in the home an opportunity to disclose with a trusted adult. The purpose for this solution is to prevent the crime of online child sexual exploitation before it occurs and to arm the youth with the tools to contact safe adults if and when it happens.
In closing, I went to hell a few times so that you didn’t have to. I spoke to the mothers of survivors of minors sexually exploited online—their tears could fill rivers. I’ve spoken with political dissidents who yearned to be free from authoritarian surveillance states. The only balance that I’ve found is freedom online for citizens around the globe and prevention from the dangers of that for the youth. Don’t slow down innovation and freedom. Educate, prepare, adapt, and look for solutions.
I’m not perfect and I’m sure that there are errors in this piece. I hope that you find them and it starts a conversation.

2025-05-24 12:06:36Throughout history, money has always been under the control of central authorities, such as governments and banks. These intermediaries have set the rules of the financial system, controlled the issuance of currency, and overseen transactions. However, with the emergence of Bitcoin, a new paradigm began to take shape: decentralized money. This transformation represents a profound shift in how people store and transfer value, challenging the traditional financial model.
- The traditional model: centralized money
01 - Dependence on intermediaries: To carry out transactions, people rely on banks, governments, and other regulatory entities.
02 - Inflation and devaluation: Central banks can print money endlessly, often leading to a loss in purchasing power.
03 - Censorship and restrictions: Access to money can be denied for political, bureaucratic, or institutional reasons, limiting individuals’ financial freedom.
Despite being the dominant model for centuries, the centralized system has shown its vulnerabilities through numerous economic and political crises. It was in this context that Bitcoin emerged as an innovative alternative.
- The revolution of decentralized money
01 - Elimination of intermediaries: Transactions can be made directly between users, without the need for banks or financial companies.
02 - Limited and predictable supply: Bitcoin has a fixed cap of 21 million units, preventing the inflation caused by excessive money printing.
03 - Censorship resistance: No entity can block or prevent transactions, ensuring full financial freedom.
04 - Self-custody: Each user can hold their own funds without relying on a bank or any other institution.
This paradigm shift has a significant impact not only on the financial system but also on how people interact with money and protect their wealth.
Challenges and opposition to financial decentralization
The transition to a decentralized financial system faces several challenges, the main one being resistance from traditional institutions. Banks and governments see Bitcoin as a threat to their control over money and seek to regulate or limit its adoption.
There are also technical and educational barriers. Many people still do not fully understand how Bitcoin works, which can hinder its adoption. However, as more people become aware of the benefits of decentralized money, its use is likely to grow.
In summary, the shift from a centralized financial system to a decentralized one represents one of the most significant transformations of the digital era. Bitcoin leads this movement by offering a censorship-resistant, transparent, and accessible alternative. Despite opposition from the traditional system, the decentralization of money continues to gain momentum, providing greater autonomy and financial freedom to people around the world. This revolution is not just technological, but also social and economic—redefining the way the world understands and uses money.
Thank you very much for reading this far. I hope everything is well with you, and sending a big hug from your favorite Bitcoiner maximalist from Madeira. Long live freedom!

2025-05-16 17:51:54In much of the world, it is incredibly difficult to access U.S. dollars. Local currencies are often poorly managed and riddled with corruption. Billions of people demand a more reliable alternative. While the dollar has its own issues of corruption and mismanagement, it is widely regarded as superior to the fiat currencies it competes with globally. As a result, Tether has found massive success providing low cost, low friction access to dollars. Tether claims 400 million total users, is on track to add 200 million more this year, processes 8.1 million transactions daily, and facilitates $29 billion in daily transfers. Furthermore, their estimates suggest nearly 40% of users rely on it as a savings tool rather than just a transactional currency.
Tether’s rise has made the company a financial juggernaut. Last year alone, Tether raked in over $13 billion in profit, with a lean team of less than 100 employees. Their business model is elegantly simple: hold U.S. Treasuries and collect the interest. With over $113 billion in Treasuries, Tether has turned a straightforward concept into a profit machine.
Tether’s success has resulted in many competitors eager to claim a piece of the pie. This has triggered a massive venture capital grift cycle in USD tokens, with countless projects vying to dethrone Tether. Due to Tether’s entrenched network effect, these challengers face an uphill battle with little realistic chance of success. Most educated participants in the space likely recognize this reality but seem content to perpetuate the grift, hoping to cash out by dumping their equity positions on unsuspecting buyers before they realize the reality of the situation.
Historically, Tether’s greatest vulnerability has been U.S. government intervention. For over a decade, the company operated offshore with few allies in the U.S. establishment, making it a major target for regulatory action. That dynamic has shifted recently and Tether has seized the opportunity. By actively courting U.S. government support, Tether has fortified their position. This strategic move will likely cement their status as the dominant USD token for years to come.
While undeniably a great tool for the millions of users that rely on it, Tether is not without flaws. As a centralized, trusted third party, it holds the power to freeze or seize funds at its discretion. Corporate mismanagement or deliberate malpractice could also lead to massive losses at scale. In their goal of mitigating regulatory risk, Tether has deepened ties with law enforcement, mirroring some of the concerns of potential central bank digital currencies. In practice, Tether operates as a corporate CBDC alternative, collaborating with authorities to surveil and seize funds. The company proudly touts partnerships with leading surveillance firms and its own data reveals cooperation in over 1,000 law enforcement cases, with more than $2.5 billion in funds frozen.
The global demand for Tether is undeniable and the company’s profitability reflects its unrivaled success. Tether is owned and operated by bitcoiners and will likely continue to push forward strategic goals that help the movement as a whole. Recent efforts to mitigate the threat of U.S. government enforcement will likely solidify their network effect and stifle meaningful adoption of rival USD tokens or CBDCs. Yet, for all their achievements, Tether is simply a worse form of money than bitcoin. Tether requires trust in a centralized entity, while bitcoin can be saved or spent without permission. Furthermore, Tether is tied to the value of the US Dollar which is designed to lose purchasing power over time, while bitcoin, as a truly scarce asset, is designed to increase in purchasing power with adoption. As people awaken to the risks of Tether’s control, and the benefits bitcoin provides, bitcoin adoption will likely surpass it.

2025-03-15 23:00:40I want to see Nostr succeed. If you can think of a way I can help make that happen, I’m open to it. I’d like your suggestions.
My schedule’s shifting soon, and I could volunteer a few hours a week to a Nostr project. I won’t have more total time, but how I use it will change.
Why help? I care about freedom. Nostr’s one of the most powerful freedom tools I’ve seen in my lifetime. If I believe that, I should act on it.
I don’t care about money or sats. I’m not rich, I don’t have extra cash. That doesn’t drive me—freedom does. I’m volunteering, not asking for pay.
I’m not here for clout. I’ve had enough spotlight in my life; it doesn’t move me. If I wanted clout, I’d be on Twitter dropping basic takes. Clout’s easy. Freedom’s hard. I’d rather help anonymously. No speaking at events—small meetups are cool for the vibe, but big conferences? Not my thing. I’ll never hit a huge Bitcoin conference. It’s just not my scene.
That said, I could be convinced to step up if it’d really boost Nostr—as long as it’s legal and gets results.
In this space, I’d watch for social engineering. I watch out for it. I’m not here to make friends, just to help. No shade—you all seem great—but I’ve got a full life and awesome friends irl. I don’t need your crew or to be online cool. Connect anonymously if you want; I’d encourage it.
I’m sick of watching other social media alternatives grow while Nostr kinda stalls. I could trash-talk, but I’d rather do something useful.
Skills? I’m good at spotting social media problems and finding possible solutions. I won’t overhype myself—that’s weird—but if you’re responding, you probably see something in me. Perhaps you see something that I don’t see in myself.
If you need help now or later with Nostr projects, reach out. Nostr only—nothing else. Anonymous contact’s fine. Even just a suggestion on how I can pitch in, no project attached, works too. 💜
Creeps or harassment will get blocked or I’ll nuke my simplex code if it becomes a problem.

2025-05-24 11:00:40The upcoming Bitcoin 2025 conference, scheduled from May 27–29 at the Venetian Conference Center in Las Vegas, is set to make history with an official attempt to break the GUINNESS WORLD RECORDS® title for the most Bitcoin point-of-sale transactions in an eight-hour period.
Organized by BTC Inc, the event will showcase Bitcoin’s evolution from a digital capital asset to a practical medium of exchange, leveraging the latest advancements in payment technology.
Tap-to-Pay with Lightning-Ready Bolt Cards
To facilitate this record-setting attempt, 4,000 Lightning-ready Bolt Cards will be distributed to conference attendees.
— Uncle Rockstar Developer (@r0ckstardev) May 15, 2025
These NFC-enabled cards allow users to make instant, contactless Bitcoin payments at vendor booths throughout the expo-no apps or QR codes required, just a simple tap.
The cards are available in four collectible designs, each featuring a prominent figure in Bitcoin’s history: Senator Cynthia Lummis, Michael Saylor, Satoshi Nakamoto, and Jack Dorsey.
Each attendee will receive a randomly assigned card, making them both functional and collectible souvenirs.
Senator Lummis: A Playful Provocation
Notably, one of the card designs features Senator Cynthia Lummis with laser eyes-a playful nod to her reputation as a leading Bitcoin advocate in US politics.
While Lummis is known for her legislative efforts to promote Bitcoin integration, she has publicly stated she prefers to “spend dollars and save Bitcoin,” viewing BTC as a long-term store of value rather than a daily currency.
The choice to feature her on the Bolt Card, could be suggested by Rockstar Dev of the BTC Pay Server Foundation, perhaps a lighthearted way to highlight the ongoing debate about Bitcoin’s role in everyday payments.
Nothing cracks me up quite like a senator that wants the US to buy millions of Bitcoin use dollars to buy a beer at a Bitcoin bar.
This is how unserious some of you are. pic.twitter.com/jftIEggmip
— Magoo PhD (@HodlMagoo) April 4, 2025
How Bolt Cards and the Lightning Network Work
Bolt Cards are physical cards equipped with NFC (Near Field Communication) technology, similar to contactless credit or debit cards. When linked to a compatible Lightning wallet, they enable users to make Bitcoin payments over the Lightning Network by simply tapping the card at a point-of-sale terminal.
The Lightning Network is a second-layer protocol built on top of Bitcoin, designed to facilitate instant, low-cost transactions ideal for everyday purchases.
This integration aims to make Bitcoin as easy to use as traditional payment methods, eliminating the need for QR code scanning or mobile apps.
A Showcase for Bitcoin’s Real-World Usability
With over 30,000 attendees, 300 exhibitors, and 500 speakers expected, the Bitcoin 2025 conference is poised to be the largest Bitcoin event of the year-and potentially the most transactional.
The event will feature on-site activations such as the Official Bitcoin Magazine Store, where all merchandise will be available at a 21% discount for those paying with Bitcoin via the Lightning Network-a nod to Bitcoin’s 21 million coin supply limit.
By deeply integrating Lightning payments into the conference experience, organizers hope to demonstrate Bitcoin’s readiness for mainstream commerce and set a new benchmark for its practical use as a currency.
Conclusion
The Guinness World Record attempt at Bitcoin 2025 is more than a publicity stunt-it’s a bold demonstration of Bitcoin’s technological maturity and its potential to function as a modern, everyday payment method.
Whether or not the record is set, the event will serve as a milestone in the ongoing journey to make Bitcoin a truly global, user-friendly currency

@ 57d1a264:69f1fee1
2025-05-16 07:51:08Payjoin allows the sender and receiver of an on-chain payment to collaborate and create a transaction that breaks on-chain heuristics, allowing a more private transaction with ambiguous payment amount and UTXO ownership. Additionally, it can also be used for UTXO consolidation (receiver saves future fees) and batching payments (receiver can make payment(s) of their own in the process of receiving one), also known as transaction cut-through. Other than improved privacy, the rest of the benefits are typically applicable to the receiver, not the sender.
BIP-78 was the original payjoin protocol that required the receiver to run a endpoint/server (always online) in order to mediate the payjoin process. Payjoin adoption has remained pretty low, something attributed to the server & perpetual online-ness requirement. This is the motivation for payjoin v2.
The purpose of the one-pager is to analyse the protocol, and highlight the UX issues or tradeoffs it entails, so that the payjoin user flows can be appropriately designed and the tradeoffs likewise communicated. A further document on UX solutions might be needed to identify solutions and opportunities
The following observations are generally limited to individual users transacting through their mobile devices:
While users naturally want better privacy and fee-savings, they also want to minimise friction and minimise (optimise) payment time. These are universal and more immediate needs since they deal with the user experience.
Added manual steps
TL;DR v2 payjoin eliminates server & simultaneous user-liveness requirements (increasing TAM, and opportunities to payjoin, as a result) by adding manual steps.
Usually, the extent of the receiver's involvement in the transaction process is limited to sharing their address with the sender. Once they share the address/URI, they can basically forget about it. In the target scenario for v2 payjoin, the receiver must come online again (except they have no way of knowing "when") to contribute input(s) and sign the PSBT. This can be unexpected, unintuitive and a bit of a hassle.
Usually (and even with payjoin v1), the sender crafts and broadcasts the transaction in one go; meaning the user's job is done within a few seconds/minutes. With payjoin v2, they must share the original-PSBT with the receiver, and then wait for them to do their part. Once the the receiver has done that, the sender must come online to review the transaction, sign it & broadcast.
In summary,
In payjoin v1, step 3 is automated and instant, so delay 2, 3 =~ 0. As the user experiences it, the process is completed in a single session, akin to a non-payjoin transaction.
With payjoin v2, Steps 2 & 3 in the above diagram are widely spread and noticeable. These manual steps are separated by uncertain delays (more on that below) when compared to a non-payjoin transaction.
Delays
We've established that both senders and receivers must take extra manual steps to execute a payoin transaction. With payjoin v2, this process gets split into multiple sessions, since the sender and receiver are not like to be online simultaneously.
Delay 2 & 3 (see diagram above) are uncertain in nature. Most users do not open their bitcoin wallets for days or weeks! The receiver must come online before the timeout hits in order for the payjoin process to work, otherwise time is just wasted with no benefit. UX or technical solutions are needed to minimise these delays.
Delays might be exacerbated if the setup is based on hardware wallet and/or uses multisig.
Notifications or background processes
There is one major problem when we say "the user must come online to..." but in reality the user has no way of knowing there is a payjoin PSBT waiting for them. After a PSBT is sent to the relay, the opposite user would only find out about it whenever they happen to come online. Notifications and background sync processes might be necessary to minimise delays. This is absolutely essential to avert timeouts in addition to saving valuable time. Another risk is phantom payjoin stuff after the timeout is expired if receiver-side does not know it has.
Fee Savings
The following observations might be generally applicable for both original and this v2 payjoin version. Fee-savings with payjoin is a tricky topic. Of course, overall a payjoin transaction is always cheaper than 2 separate transactions, since they get to share the overhead.
Additionally, without the receiver contributing to fees, the chosen fee rate of the PSBT (at the beginning) drops, and can lead to slower confirmation. From another perspective, a sender paying with payjoin pays higher fees for similar confirmation target. This has been observed in a production wallet years back. Given that total transaction time can extend to days, the fee environment itself might change, and all this must be considered when designing the UX.
Of course, there is nothing stopping the receiver from contributing to fees, but this idea is likely entirely novel to the bitcoin ecosystem (perhaps payments ecosystem in general) and the user base. Additionally, nominally it involves the user paying fees and tolerating delays just to receive bitcoin. Without explicit incentives/features that encourage receivers to participate, payjoining might seem like an unncessary hassle.
Overall, it seems that payjoin makes UX significant tradeoffs for important privacy (and potential fee-saving) benefits. This means that the UX might have to do significant heavy-lifting, to ensure that users are not surprised, confused or frustrated when they try to transact on-chain in a privacy-friendly feature. Good, timely communication, new features for consolidation & txn-cutthrough and guided user flows seem crucial to ensure payjoin adoption and for help make on-chain privacy a reality for users.

Lego is something most of us knows. This is a opportuity to ask where is our creativity going? From the art of crafting figures to building blocks following our need and desires to have a machine thinking and building following step-by-step instructions to achieve an isolated goal.
Is the creative act then in the question itself, not anymore in the crafting? Are we just delegating the solution of problems, the thinking of how to respond to questions, to machines? Would it be different if delegated to other people?

2025-05-24 11:00:37Bitcoin FilmFest (BFF25) returns to Warsaw for its third edition, blending independent cinema—from feature films and commercials to AI-driven experimental visuals—with education and entertainment.
Hundreds of attendees from around the world will gather for three days of screenings, discussions, workshops, and networking at the iconic Kinoteka Cinema (PKiN), the same venue that hosted the festival’s first two editions in March 2023 and April 2024.
This year’s festival, themed “Beyond the Frame,” introduces new dimensions to its program, including an extra day on May 22 to celebrate Bitcoin Pizza Day, the first real-world bitcoin transaction, with what promises to be one of Europe’s largest commemorations of this milestone.
BFF25 bridges independent film, culture, and technology, with a bold focus on decentralized storytelling and creative expression. As a community-driven cultural experience with a slightly rebellious spirit, Bitcoin FilmFest goes beyond movies, yet cinema remains at its heart.
Here’s a sneak peek at the lineup, specially curated for movie buffs:
Generative Cinema – A special slot with exclusive shorts and a thematic debate on the intersection of AI and filmmaking. Featured titles include, for example: BREAK FREE, SATOSHI: THE CREATION OF BITCOIN, STRANGE CURRENCIES, and BITCOIN IS THE MYCELIUM OF MONEY, exploring financial independence, traps of the fiat system, and a better future built on sound money.
Upcoming Productions Preview – A bit over an hour-long block of unreleased pilots and works-in-progress. Attendees will get exclusive first looks at projects like FINDING HOME (a travel-meets-personal-journey series), PARALLEL SPACES (a story about alternative communities), and THE LEGEND OF LANDI (a mysterious narrative).
Freedom-Focused Ads & Campaigns – Unique screenings of video commercials, animations, and visual projects, culminating in “The PoWies” (Proof of Work-ies)—the first ever awards show honoring the best Bitcoin-only awareness campaigns.
To get an idea of what might come up at the event, here, you can preview 6 selected ads combined into two 2 videos:
Open Pitch Competition – A chance for filmmakers to present fresh ideas and unfinished projects to an audience of a dedicated jury, movie fans and potential collaborators. This competitive block isn’t just entertaining—it’s a real opportunity for creators to secure funding and partnerships.
Golden Rabbit Awards: A lively gala honoring films from the festival’s Official Selection, with awards in categories like Best Feature, Best Story, Best Short, and Audience Choice.
BFF25 Main Screenings
Sample titles from BFF25’s Official Selection:
REVOLUCIÓN BITCOIN – A documentary by Juan Pablo, making its first screening outside the Spanish-speaking world in Warsaw this May. Three years of important work, 80 powerful minutes to experience. The film explores Bitcoin’s impact across Argentina, Colombia, Mexico, El Salvador, and Spain through around 40 diverse perspectives. Screening in Spanish with English subtitles, followed by a Q&A with the director.
UNBANKABLE – Luke Willms’ directorial debut, drawing from his multicultural roots and his father’s pioneering HIV/AIDS research. An investigative documentary based on Luke’s journeys through seven African countries, diving into financial experiments and innovations—from mobile money and digital lending to Bitcoin—raising smart questions and offering potential lessons for the West. Its May appearance at BFF25 marks its largest European event to date, following festival screenings and nominations across multiple continents over the past year.
HOTEL BITCOIN – A Spanish comedy directed by Manuel Sanabria and Carlos “Pocho” Villaverde. Four friends, 4,000 bitcoins , and one laptop spark a chaotic adventure of parties, love, crime, and a dash of madness. Exploring sound money, value, and relationships through a twisting plot. The film premiered at the Tarazona and Moncayo Comedy Film Festival in August 2024. Its Warsaw screening at BFF25 (in Spanish with English subtitles) marks its first public showing outside the Spanish-speaking world.

2025-05-14 06:48:45Has the architect Greg Chasen considered it when rebuilding the house just one year before the catastrophe? Apparently not! Another of his projects was featured on the Value of Architecture as properties with design integrity.
This is a super interesting subject. The historic character, livability, and modern disaster-resistance is a triangle where you often have to pick just one or two, which leads to some tough decisions that have major impacts on families and communities. Like one of the things he mentions is that the architect completely eliminated plants from the property. That's great for fire resistance, but not so great for other things if the entire town decides to go the same route (which he does bring up later in the video). I don't think there's any objectively right answer, but definitely lots of good (and important) discussion points to be had.

2025-05-24 11:00:35Starting January 1, 2026, the United Kingdom will impose some of the world’s most stringent reporting requirements on cryptocurrency firms.
All platforms operating in or serving UK customers-domestic and foreign alike-must collect and disclose extensive personal and transactional data for every user, including individuals, companies, trusts, and charities.
This regulatory drive marks the UK’s formal adoption of the OECD’s Crypto-Asset Reporting Framework (CARF), a global initiative designed to bring crypto oversight in line with traditional banking and to curb tax evasion in the rapidly expanding digital asset sector.
What Will Be Reported?
Crypto firms must gather and submit the following for each transaction:
- User’s full legal name, home address, and taxpayer identification number
- Detailed data on every trade or transfer: type of cryptocurrency, amount, and nature of the transaction
- Identifying information for corporate, trust, and charitable clients
The obligation extends to all digital asset activities, including crypto-to-crypto and crypto-to-fiat trades, and applies to both UK residents and non-residents using UK-based platforms. The first annual reports covering 2026 activity are due by May 31, 2027.
Enforcement and Penalties
Non-compliance will carry stiff financial penalties, with fines of up to £300 per user account for inaccurate or missing data-a potentially enormous liability for large exchanges. The UK government has urged crypto firms to begin collecting this information immediately to ensure operational readiness.
Regulatory Context and Market Impact
This move is part of a broader UK strategy to position itself as a global fintech hub while clamping down on fraud and illicit finance. UK Chancellor Rachel Reeves has championed these measures, stating, “Britain is open for business – but closed to fraud, abuse, and instability”. The regulatory expansion comes amid a surge in crypto adoption: the UK’s Financial Conduct Authority reported that 12% of UK adults owned crypto in 2024, up from just 4% in 2021.
Enormous Risks for Consumers: Lessons from the Coinbase Data Breach
While the new framework aims to enhance transparency and protect consumers, it also dramatically increases the volume of sensitive personal data held by crypto firms-raising the stakes for cybersecurity.
The risks are underscored by the recent high-profile breach at Coinbase, one of the world’s largest exchanges.
In May 2025, Coinbase disclosed that cybercriminals, aided by bribed offshore contractors, accessed and exfiltrated customer data including names, addresses, government IDs, and partial bank details.
The attackers then used this information for sophisticated phishing campaigns, successfully deceiving some customers into surrendering account credentials and funds.
“While private encryption keys remained secure, sufficient customer information was exposed to enable sophisticated phishing attacks by criminals posing as Coinbase personnel.”
Coinbase now faces up to $400 million in compensation costs and has pledged to reimburse affected users, but the incident highlights the systemic vulnerability created when large troves of personal data are centralized-even if passwords and private keys are not directly compromised. The breach also triggered a notable drop in Coinbase’s share price and prompted a $20 million bounty for information leading to the attackers’ capture.
The Bottom Line
The UK’s forthcoming crypto reporting regime represents a landmark in financial regulation, promising greater transparency and tax compliance. However, as the Coinbase episode demonstrates, the aggregation of sensitive user data at scale poses a significant cybersecurity risk.
As regulators push for more oversight, the challenge will be ensuring that consumer protection does not become a double-edged sword-exposing users to new threats even as it seeks to shield them from old ones.

2025-05-24 11:00:34This article was originally published on aier.org
Even after eleven years experience, and a per Bitcoin price of nearly $20,000, the incredulous are still with us. I understand why. Bitcoin is not like other traditional financial assets.
Even describing it as an asset is misleading. It is not the same as a stock, as a payment system, or a money. It has features of all these but it is not identical to them.
What Bitcoin is depends on its use as a means of storing and porting value, which in turn rests of secure titles to ownership of a scarce good. Those without experience in the sector look at all of this and get frustrated that understanding why it is valuable is not so easy to grasp.
In this article, I’m updating an analysis I wrote six years ago. It still holds up. For those who don’t want to slog through the entire article, my thesis is that Bitcoin’s value obtains from its underlying technology, which is an open-source ledger that keeps track of ownership rights and permits the transfer of these rights. Bitcoin managed to bundle its unit of account with a payment system that lives on the ledger. That’s its innovation and why it obtained a value and that value continues to rise.
Consider the criticism offered by traditional gold advocates, who have, for decades, pushed the idea that sound money must be backed by something real, hard, and independently valuable. Bitcoin doesn’t qualify, right? Maybe it does.
Bitcoin first emerged as a possible competitor to national, government-managed money in 2009. Satoshi Nakamoto’s white paper was released October 31, 2008. The structure and language of this paper sent the message: This currency is for computer technicians, not economists nor political pundits. The paper’s circulation was limited; novices who read it were mystified.
But the lack of interest didn’t stop history from moving forward. Two months later, those who were paying attention saw the emergence of the “Genesis Block,” the first group of bitcoins generated through Nakamoto’s concept of a distributed ledger that lived on any computer node in the world that wanted to host it.
Here we are all these years later and a single bitcoin trades at $18,500. The currency is held and accepted by many thousands of institutions, both online and offline. Its payment system is very popular in poor countries without vast banking infrastructures but also in developed countries. And major institutions—including the Federal Reserve, the OECD, the World Bank, and major investment houses—are paying respectful attention and weaving blockchain technology into their operations.
Enthusiasts, who are found in every country, say that its exchange value will soar even more in the future because its supply is strictly limited and it provides a system vastly superior to government money. Bitcoin is transferred between individuals without a third party. It is relatively low-cost to exchange. It has a predictable supply. It is durable, fungible, and divisible: all crucial features of money. It creates a monetary system that doesn’t depend on trust and identity, much less on central banks and government. It is a new system for the digital age.
Hard lessons for hard money
To those educated in the “hard money” tradition, the whole idea has been a serious challenge. Speaking for myself, I had been reading about bitcoin for two years before I came anywhere close to understanding it. There was just something about the whole idea that bugged me. You can’t make money out of nothing, much less out of computer code. Why does it have value then? There must be something amiss. This is not how we expected money to be reformed.
There’s the problem: our expectations. We should have been paying closer attention to Ludwig von Mises’ theory of money’s origins—not to what we think he wrote, but to what he actually did write.
In 1912, Mises released The Theory of Money and Credit. It was a huge hit in Europe when it came out in German, and it was translated into English. While covering every aspect of money, his core contribution was in tracing the value and price of money—and not just money itself—to its origins. That is, he explained how money gets its price in terms of the goods and services it obtains. He later called this process the “regression theorem,” and as it turns out, bitcoin satisfies the conditions of the theorem.
Mises’ teacher, Carl Menger, demonstrated that money itself originates from the market—not from the State and not from social contract. It emerges gradually as monetary entrepreneurs seek out an ideal form of commodity for indirect exchange. Instead of merely bartering with each other, people acquire a good not to consume, but to trade. That good becomes money, the most marketable commodity.
But Mises added that the value of money traces backward in time to its value as a bartered commodity. Mises said that this is the only way money can have value.
The theory of the value of money as such can trace back the objective exchange value of money only to that point where it ceases to be the value of money and becomes merely the value of a commodity…. If in this way we continually go farther and farther back we must eventually arrive at a point where we no longer find any component in the objective exchange value of money that arises from valuations based on the function of money as a common medium of exchange; where the value of money is nothing other than the value of an object that is useful in some other way than as money…. Before it was usual to acquire goods in the market, not for personal consumption, but simply in order to exchange them again for the goods that were really wanted, each individual commodity was only accredited with that value given by the subjective valuations based on its direct utility.
Mises’ explanation solved a major problem that had long mystified economists. It is a narrative of conjectural history, and yet it makes perfect sense. Would salt have become money had it otherwise been completely useless? Would beaver pelts have obtained monetary value had they not been useful for clothing? Would silver or gold have had money value if they had no value as commodities first? The answer in all cases of monetary history is clearly no. The initial value of money, before it becomes widely traded as money, originates in its direct utility. It’s an explanation that is demonstrated through historical reconstruction. That’s Mises’ regression theorem.
Bitcoin’s Use Value
At first glance, bitcoin would seem to be an exception. You can’t use a bitcoin for anything other than money. It can’t be worn as jewelry. You can’t make a machine out of it. You can’t eat it or even decorate with it. Its value is only realized as a unit that facilitates indirect exchange. And yet, bitcoin already is money. It’s used every day. You can see the exchanges in real time. It’s not a myth. It’s the real deal.
It might seem like we have to choose. Is Mises wrong? Maybe we have to toss out his whole theory. Or maybe his point was purely historical and doesn’t apply in the future of a digital age. Or maybe his regression theorem is proof that bitcoin is just an empty mania with no staying power, because it can’t be reduced to its value as a useful commodity.
And yet, you don’t have to resort to complicated monetary theory in order to understand the sense of alarm surrounding bitcoin. Many people, as I did, just have a feeling of uneasiness about a money that has no basis in anything physical. Sure, you can print out a bitcoin on a piece of paper, but having a paper with a QR code or a public key is not enough to relieve that sense of unease.
How can we resolve this problem? In my own mind, I toyed with the issue for more than a year. It puzzled me. I wondered if Mises’ insight applied only in a pre-digital age. I followed the speculations online that the value of bitcoin would be zero but for the national currencies into which it is converted. Perhaps the demand for bitcoin overcame the demands of Mises’ scenario because of a desperate need for something other than the dollar.
As time passed—and I read the work of Konrad Graf, Peter Surda, and Daniel Krawisz—finally the resolution came. Bitcoin is both a payment system and a money. The payment system is the source of value, while the accounting unit merely expresses that value in terms of price. The unity of money and payment is its most unusual feature, and the one that most commentators have had trouble wrapping their heads around.
We are all used to thinking of currency as separate from payment systems. This thinking is a reflection of the technological limitations of history. There is the dollar and there are credit cards. There is the euro and there is PayPal. There is the yen and there are wire services. In each case, money transfer relies on third-party service providers. In order to use them, you need to establish what is called a “trust relationship” with them, which is to say that the institution arranging the deal has to believe that you are going to pay.
This wedge between money and payment has always been with us, except for the case of physical proximity.
If I give you a dollar for your pizza slice, there is no third party. But payment systems, third parties, and trust relationships become necessary once you leave geographic proximity. That’s when companies like Visa and institutions like banks become indispensable. They are the application that makes the monetary software do what you want it to do.
The hitch is that

2025-05-14 06:12:19We asked members of the design community to choose an artifact that embodies craft—something that speaks to their understanding of what it means to make with intention. Here’s what they shared.
A vintage puzzle box, a perfectly tuned guitar, an AI-powered poetry camera. A daiquiri mixed with precision. A spreadsheet that still haunts muscle memory. Each artifact tells a story: not just about the thing itself, but about the choices of the creator behind it. What to refine, what to leave raw. When to push forward, when to let go. Whether built to last for generations or designed to delight in a fleeting moment, the common thread is that great craft doesn’t happen by accident. It’s made.
On the application of craft
Even the most experienced makers can benefit from building structure and intention into their practice. From sharpening your storytelling to designing quality products, these pieces offer practical ways to uplevel your craft.

2025-05-14 05:56:15Shanghai: Bus Stops Here
A new crowd-sourced transit platform allows riders to propose, vote on, and activate new bus lines in as little as three days.
From early-morning school drop-offs to seniors booking rides to the hospital, from suburban commuters seeking a faster link to the metro to families visiting ancestral graves, Shanghai is rolling out a new kind of public bus — one that’s designed by commuters, and launched only when enough riders request it.
Branded “DZ” for dingzhi, or “customized,” the system invites residents to submit proposed routes through a city-run platform. Others with similar travel needs can opt in or vote, and if demand meets the threshold — typically 15 to 20 passengers per trip — the route goes live.
More than 220 DZ routes have already launched across all 16 city districts. Through an online platform opened May 8, users enter start and end points, preferred times, and trip frequency. If approved, routes can begin running in as little as three days.

Bitcoin ຖືກສ້າງຂຶ້ນບົນພື້ນຖານອິນເຕີເນັດ ເຮັດໃຫ້ການສື່ສານຄວາມຄິດເຫັນຂອງຜູ້ຄົນສາມາດເຮັດໄດ້ຢ່າງໄວວາ. ຍິ່ງໄປກວ່ານັ້ນ Bitcoin ມີລັກສະນະກະຈາຍສູນ (decentralized) ແລະບໍ່ມີຜູ້ຄວບຄຸມສູນກາງ ຈຶ່ງເຮັດໃຫ້ຄົນສາມາດຕັດສິນໃຈຊື້ຂາຍໄດ້ຢ່າງໄວວາ.
ສິ່ງນີ້ເຮັດໃຫ້ລາຄາຂອງ Bitcoin ສາມາດສະທ້ອນຄວາມຄິດເຫັນຂອງຄົນໄດ້ແບບເວລາຈິງ (real-time). ແລະເນື່ອງຈາກມະນຸດເຮົາມີຄວາມຄິດທີ່ບໍ່ແນ່ນອນ ມີການປ່ຽນແປງ ລາຄາຂອງ Bitcoin ຈຶ່ງປ່ຽນແປງໄປຕາມຄວາມຄິດເຫັນລວມຂອງຜູ້ຄົນແບບທັນທີ.
ປັດໄຈທີ່ເພີ່ມຄວາມຜັນຜວນ:
ຂະໜາດຕະຫຼາດທີ່ຍັງນ້ອຍ: ເມື່ອປຽບທຽບກັບຕະຫຼາດການເງິນແບບດັ້ງເດີມ ຕະຫຼາດ Bitcoin ຍັງມີຂະໜາດນ້ອຍ ເຮັດໃຫ້ການຊື້ຂາຍຈຳນວນໃຫຍ່ສາມາດສົ່ງຜົນກະທົບຕໍ່ລາຄາໄດ້ຫຼາຍ.
ການຄ້າຂາຍຕະຫຼອດ 24/7: ບໍ່ເຫມືອນກັບຕະຫຼາດຫຼັກຊັບທີ່ມີເວລາເປີດປິດ Bitcoin ສາມາດຊື້ຂາຍໄດ້ຕະຫຼອດເວລາ ເຮັດໃຫ້ການປ່ຽນແປງລາຄາສາມາດເກີດຂຶ້ນໄດ້ທຸກເວລາ.
ການປຽບທຽບກັບສິນຊັບອື່ນ
ເມື່ອປຽບທຽບກັບສິນຊັບອື່ນທີ່ມີການຄວບຄຸມ ເຊັ່ນ ສະກຸນເງິນທ້ອງຖິ່ນຫຼືທອງຄຳ ທີ່ເບິ່ງຄືວ່າມີຄວາມຜັນຜວນໜ້ອຍກວ່າ Bitcoin ນັ້ນ ບໍ່ແມ່ນຫມາຍຄວາມວ່າພວກມັນບໍ່ມີຄວາມຜັນຜວນ. ແຕ່ເປັນເພາະມີການຄວບຄຸມຈາກອົງການສູນກາງ ເຮັດໃຫ້ການສື່ສານຄວາມຄິດເຫັນຂອງຄົນໄປຮອດຕະຫຼາດບໍ່ແບບເວລາຈິງ.
ດັ່ງນັ້ນ ສິ່ງທີ່ເຮົາເຫັນແມ່ນການຊັກຊ້າ (delay) ໃນການສະແດງຄວາມຄິດເຫັນທີ່ແທ້ຈິງອອກມາເທົ່ານັ້ນ ບໍ່ແມ່ນຄວາມໝັ້ນຄົງຂອງມູນຄ່າ.
ກົນໄກການຄວບຄຸມແລະຜົນກະທົບ:
ສະກຸນເງິນ: ທະນາຄານກາງສາມາດພິມເງິນ ປັບອັດຕາດອກເບີ້ຍ ແລະແຊກແຊງຕະຫຼາດ ເຮັດໃຫ້ລາຄາບໍ່ສະທ້ອນມູນຄ່າທີ່ແທ້ຈິງໃນທັນທີ.
ຫຼັກຊັບ: ມີລະບຽບການຫຼາຍຢ່າງ ເຊັ່ນ ການຢຸດການຊື້ຂາຍເມື່ອລາຄາປ່ຽນແປງຫຼາຍເກີນໄປ (circuit breakers) ທີ່ຂັດຂວາງການສະແດງຄວາມຄິດເຫັນທີ່ແທ້ຈິງ.
ທອງຄຳ: ຖຶງແມ່ນຈະເປັນສິນຊັບທີ່ບໍ່ມີການຄວບຄຸມ ແຕ່ຕະຫຼາດທອງຄຳມີຂະໜາດໃຫຍ່ກວ່າ Bitcoin ຫຼາຍ ແລະມີການຄ້າແບບດັ້ງເດີມທີ່ຊ້າກວ່າ.
ບົດສະຫຼຸບ
ການປຽບທຽບຄວາມຜັນຜວນລະຫວ່າງ Bitcoin ແລະສິນຊັບອື່ນໆ ໂດຍໃຊ້ໄລຍະເວລາສັ້ນນັ້ນ ບໍ່ມີຄວາມສົມເຫດສົມຜົນປານໃດ ເພາະວ່າປັດໄຈເລື້ອງການຊັກຊ້າໃນການສະແດງຄວາມຄິດເຫັນນີ້ແມ່ນສິ່ງສຳຄັນທີ່ສົ່ງຜົນຕໍ່ລາຄາທີ່ແທ້ຈິງ.

2025-03-08 07:08:11Bitcoin Core: The Reference Implementation
ผู้คนจะยอมรับเงินใด ๆ เพื่อแลกเปลี่ยนกับสินค้าและบริการก็ต่อเมื่อคนนั้น ๆ เชื่อว่าเงินนี้จะมีมูลค่าในอนาคต เงินปลอมหรือเงินที่เสื่อมค่าโดยไม่คาดคิดนั้นอาจไม่สามารถใช้ได้ในอนาคต ดังนั้นทุกคนที่รับบิตคอยน์จึงมีแรงจูงใจที่แข็งแกร่งในการตรวจสอบความถูกต้องของบิตคอยน์ที่พวกเขาได้รับ ระบบของบิตคอยน์นั้นถูกออกแบบมาให้เข้าถึง, ป้องกันการปลอมแปลง, การเสื่อมค่า และปัญหาสำคัญอื่น ๆ ได้อย่างสมบูรณ์ได้ด้วยคอมพิวเตอร์ทั่วไป โดยซอฟต์แวร์ที่ให้ฟังก์ชันนี้เรียกว่า Full node ซึ่งทำหน้าที่ตรวจสอบธุรกรรมบิตคอยน์ทุกครั้งที่ได้รับการยืนยันตามกฎของระบบ นอกจากนี้ Full node ยังสามารถให้เครื่องมือและข้อมูลเพื่อทำความเข้าใจการทำงานของบิตคอยน์และสภาพปัจจุบันของเครือข่าย
ในบทนี้เอง เราจะทำการติดตั้ง Bitcoin Core ซึ่งเป็นซอฟต์แวร์ที่ผู้ใช้งาน Full node ส่วนใหญ่เลือกใช้เพื่อเป็นประตูบานแรกในการเข้าถึงระบบนิเวศของบิตคอยน์ เราจะตรวจสอบบล็อก ธุรกรรม และข้อมูลอื่น ๆ จากโหนดของคุณ ซึ่งเป็นข้อมูลที่เชื่อถือได้ (ไม่ใช่เพราะหน่วยงานทรงอำนาจกำหนดให้เป็นเช่นนั้น) แต่เป็นเพราะโหนดของคุณได้ตรวจสอบข้อมูลนั้นอย่างอิสระ ตลอดเนื้อหาที่เหลือในหนังสือเล่มนี้ เราจะใช้ Bitcoin Core เพื่อสร้างและตรวจสอบข้อมูลที่เกี่ยวข้องกับบล็อกเชนและเครือข่าย
จาก Bitcoin สู่ Bitcoin Core
บิตคอยน์เป็นโครงการโอเพ่นซอร์ส โดยซอร์สโค้ดทั้งหมดก็สามารถดาวน์โหลดและใช้งานได้ฟรีภายใต้ใบอณุญาตแบบเปิด (MIT License) นอกจากจะเป็นโอเพ่นซอร์สแล้วบิตคอยน์ยังได้รับการพัฒนาโดยชุมชนอาสาสมัครแบบเปิดกว้าง แน่นอนว่าในช่วงแรกนั้นชุมชนนี้ประกอบด้วย Satoshi Nakamoto เพียงคนเดียว แต่ภายในปี 2023 ซอร์สโค้ดของบิตคอยน์มีผู้ร่วมพัฒนามากกว่า 1,000 คน
เมื่อ Satoshi Nakamoto ได้สร้างซอฟแวร์บิตคอยน์ตัวนี้และพัฒนามันจนเกือบสมบูรณ์ก่อนแล้วจึงเผยแพร่เอกสารไวท์เปเปอร์ เขาน่าจะต้องการให้มั่นใจว่าการใช้งานจริงสามารถทำงานได้ก่อนเผยแพร่เอกสาร โดยซอฟต์แวร์เวอร์ชันแรกที่รู้จักในชื่อ "Bitcoin" นั้นได้รับการปรับปรุงและพัฒนามาอย่างมาก จนได้กลายเป็นสิ่งที่เรารู้จักกันในชื่อ Bitcoin Core และเพื่อแยกความแตกต่างจากการใช้งานอื่น ๆ Bitcoin Core เป็นซอฟต์แวร์ต้นแบบอ้างอิง (reference implementation) ของระบบบิตคอยน์ซึ่งแสดงวิธีการทำงานของแต่ละส่วนในเชิงเทคโนโลยี นอกจากนี้ Bitcoin Core รวมถึงการใช้งานฟังก์ชันทั้งหมดของบิตคอยน์ เช่น กระเป๋าเงิน เครื่องมือตรวจสอบธุรกรรมและบล็อก เครื่องมือสำหรับการสร้างบล็อก และส่วนต่าง ๆ ของการสื่อสารแบบ peer-to-peer ของบิตคอยน์
Bitcoin Development Environment
สำหรับนักพัฒนาที่ต้องการเขียนแอปพลิเคชันเกี่ยวกับบิตคอยน์ ทั้งการตั้งค่าสภาพแวดล้อมสำหรับการพัฒนาพร้อมเครื่องมือ ไลบรารี และซอฟต์แวร์สนับสนุนเป็นสิ่งสำคัญ ซึ่งเนื้อหาในบทนี้นั้นจะเป็นเรื่องทางเทคนิคอลค่อนข้างเยอะ ในบทนี้เราจะอธิบายขั้นตอนการตั้งค่าอย่างละเอียด หากคุณพบว่าเนื้อหานี้ซับซ้อนเกินไป (และไม่ได้ต้องการตั้งค่าสภาพแวดล้อมสำหรับการพัฒนาจริง ๆ) คุณสามารถข้ามไปยังบทถัดไปที่มีเนื้อหาน้อยทางเทคนิคกว่าได้
มาคอมไพล์ Bitcoin core จากซอร์สโค้ดกันเถอะ !!
ซอร์สโค้ดทั้งหมดของ BItcoin Core นั้นสามารถดาวน์โหลดได้ในรูปแบบไฟล์อาร์ไคฟ์หรือโดยการโคลนที่เก็บซอร์สโค้ดจาก GitHub โดยตรง บนหน้าดาวน์โหลดของ Bitcoin Core ให้เลือกเวอร์ชันล่าสุดและดาวน์โหลดไฟล์อัดบีบของซอร์สโค้ด หรือใช้คำสั่ง Git เพื่อสร้างสำเนาซอร์สโค้ดบนเครื่องของคุณจากหน้า GitHub ของ Bitcoin
TIP: ในตัวอย่างหลาย ๆ ส่วนของบทนี้ เราจะใช้ อินเทอร์เฟซบรรทัดคำสั่ง (Command-Line Interface - CLI) ของระบบปฏิบัติการ หรือที่เรียกว่า "shell" ซึ่งสามารถเข้าถึงได้ผ่านแอปพลิเคชัน terminal โดย shell จะแสดง พรอมต์ (prompt) เพื่อรอรับคำสั่งที่คุณพิมพ์ จากนั้นจะแสดงผลลัพธ์ออกมาแล้วรอรับคำสั่งถัดไป
TIP จากหลาม: แบบง่าย ๆ ก็คือไม่ต้องพิมพ์ $ และถ้าพิมพ์จบหนึ่งคำสั่งก็กด enter ซ่ะด้วย
ขั้นตอนในการลง bitcoin core มีดังนี้:
- สั่ง git clone เพื่อทำการสร้างสำเนาของซอร์สโค้ดลงในเครื่องของเรา ``` $ git clone https://github.com/bitcoin/bitcoin.git Cloning into 'bitcoin'... remote: Enumerating objects: 245912, done. remote: Counting objects: 100% (3/3), done. remote: Compressing objects: 100% (2/2), done. remote: Total 245912 (delta 1), reused 2 (delta 1), pack-reused 245909 Receiving objects: 100% (245912/245912), 217.74 MiB | 13.05 MiB/s, done. Resolving deltas: 100% (175649/175649), done.
```
TIP: Git เป็นระบบควบคุมเวอร์ชันแบบกระจายที่ใช้กันอย่างแพร่หลายและเป็นส่วนสำคัญในเครื่องมือของนักพัฒนาซอฟต์แวร์ คุณอาจจำเป็นต้องติดตั้งคำสั่ง git หรือส่วนต่อประสานกราฟิก (GUI) สำหรับ Git บนระบบปฏิบัติการของคุณ หากยังไม่มี
- เมื่อการโคลน Git เสร็จสมบูรณ์แล้ว คุณจะมีสำเนาท้องถิ่นครบถ้วนของที่เก็บซอร์สโค้ดในไดเรกทอรี bitcoin ให้เปลี่ยนไปยังไดเรกทอรีนี้โดยใช้คำสั่ง cd:
``` $ cd bitcoin
3. เลือก version ของ bitcoin core: โดยค่าเริ่มต้น สำเนาจองเราจะซิงโครไนซ์กับโค้ดล่าสุด ซึ่งอาจเป็นเวอร์ชันที่ไม่เสถียรหรือเบต้าของ Bitcoin ก่อนที่จะคอมไพล์โค้ด ให้เลือกเวอร์ชันเฉพาะโดยการตรวจสอบ (checkout) แท็กของการปล่อย (release tag) ซึ่งจะซิงโครไนซ์สำเนาท้องถิ่นกับสแนปช็อตของที่เก็บซอร์สโค้ดที่ระบุด้วยแท็ก แท็กเหล่านี้ถูกใช้งานโดยนักพัฒนาเพื่อระบุเวอร์ชันของโค้ดตามหมายเลขเวอร์ชัน ซึ่งทำได้โดยใช้คำสั่ง git tag
$ git tag v0.1.5 v0.1.6test1 v0.10.0 ... v0.11.2 v0.11.2rc1 v0.12.0rc1 v0.12.0rc2 ...รายการแท็กจะแสดงทุกเวอร์ชันที่ปล่อยออกมา โดยทั่วไป release candidates (เวอร์ชันทดสอบ) จะมีต่อท้ายว่า "rc" ส่วนเวอร์ชันเสถียรที่ใช้งานในระบบ production จะไม่มีต่อท้ายอะไรเลย จากรายการด้านบน ให้เลือกเวอร์ชันที่สูงสุด ซึ่งในขณะที่เขียนบทความนี้คือ v24.0.1 เพื่อซิงโครไนซ์โค้ดท้องถิ่นกับเวอร์ชันนี้ ให้ใช้คำสั่ง:
$ git checkout v24.0.1 Note: switching to 'v24.0.1'.```
จากนั้นสั่ง git status เพื่อเช็คเวอร์ชัน
Configuring the Bitcoin Core Build
ในโค้ดของบิตคอยน์ที่เราได้ดาวน์โหลดมาในหัวข้อก่อนหน้านั้น มีเอกสารประกอบอยู่หลายไฟล์ โดยคุณสามารถดูเอกสารหลักได้จากไฟล์ README.md ในไดเรกทอรี bitcoin ในบทนี้ เราจะสร้าง daemon (เซิร์ฟเวอร์) ของ Bitcoin Core ซึ่งรู้จักกันในชื่อ bitcoind บน Linux (หรือระบบที่คล้ายกับ Unix) โดยให้ตรวจสอบคำแนะนำสำหรับการคอมไพล์ bitcoind แบบบรรทัดคำสั่งบนแพลตฟอร์มของคุณโดยอ่านไฟล์ doc/build-unix.md นอกจากนี้ ยังมีคำแนะนำสำหรับระบบอื่น ๆ ในไดเรกทอรี doc เช่น build-windows.md สำหรับ Windows จนถึงขณะนี้ คำแนะนำมีให้สำหรับ Android, FreeBSD, NetBSD, OpenBSD, macOS (OSX), Unix
หลังจากนั้นคุณควรตรวจสอบความต้องการเบื้องต้นในการสร้าง (build pre-requisites) ซึ่งระบุไว้ในส่วนแรกของเอกสารการสร้าง สิ่งเหล่านี้คือไลบรารีที่ต้องมีอยู่ในระบบของคุณก่อนที่คุณจะเริ่มคอมไพล์ Bitcoin หากมีไลบรารีที่จำเป็นหายไป กระบวนการสร้างจะล้มเหลวและแสดงข้อผิดพลาด หากเกิดปัญหานี้เพราะคุณพลาด pre-requisite คุณสามารถติดตั้งไลบรารีที่ขาดหายไปแล้วดำเนินการสร้างต่อจากจุดที่ค้างไว้
สมมุติว่า pre-requisite ถูกติดตั้งแล้ว ให้เริ่มกระบวนการสร้างโดยการสร้างชุดสคริปต์สำหรับการสร้างด้วยการรันสคริปต์ autogen.sh:
``` $ ./autogen.sh libtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, 'build-aux'. libtoolize: copying file 'build-aux/ltmain.sh' libtoolize: putting macros in AC_CONFIG_MACRO_DIRS, 'build-aux/m4'. ... configure.ac:58: installing 'build-aux/missing' src/Makefile.am: installing 'build-aux/depcomp' parallel-tests: installing 'build-aux/test-driver'
``` สคริปต์ autogen.sh นี้จะสร้างชุดสคริปต์ที่กำหนดค่าอัตโนมัติที่จะตรวจสอบระบบของคุณเพื่อค้นหาการตั้งค่าที่ถูกต้องและตรวจสอบให้แน่ใจว่ามีไลบรารีที่จำเป็นสำหรับการคอมไพล์โค้ด โดยสคริปต์ที่สำคัญที่สุดในสคริปต์เหล่านี้คือสคริปต์ configure ซึ่งมีตัวเลือกต่าง ๆ สำหรับการปรับแต่งกระบวนการสร้าง
ใช้ flag --help เพื่อดูตัวเลือกทั้งหมด:
`` $ ./configure --help
configure' configures Bitcoin Core 24.0.1 to adapt to many kinds of systems. Usage: ./configure [OPTION]... [VAR=VALUE]... ... Optional Features: --disable-option-checking ignore unrecognized --enable/--with options --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no) --enable-FEATURE[=ARG] include FEATURE [ARG=yes] --enable-silent-rules less verbose build output (undo: "make V=1") --disable-silent-rules verbose build output (undo: "make V=0") ...```
สคริปต์ configure ช่วยให้คุณสามารถเปิดหรือปิดคุณสมบัติบางอย่างของ bitcoind ผ่านการใช้ flag --enable-FEATURE และ --disable-FEATURE โดยที่ FEATURE แทนชื่อคุณสมบัติที่ระบุในข้อความช่วยเหลือ ในบทนี้ เราจะสร้าง bitcoind ด้วยคุณสมบัติตั้งต้นทั้งหมด โดยไม่ใช้ flag การกำหนดค่าเพิ่มเติม แต่คุณควรตรวจสอบตัวเลือกเหล่านี้เพื่อเข้าใจว่ามีคุณสมบัติเพิ่มเติมอะไรบ้าง หากคุณอยู่ในสภาพแวดล้อมทางการศึกษา ห้องปฏิบัติการคอมพิวเตอร์ หรือมีข้อจำกัดในการติดตั้งโปรแกรม คุณอาจต้องติดตั้งแอปพลิเคชันไว้ในไดเรกทอรี home (เช่นโดยใช้ flag --prefix=$HOME)
ตัวเลือกที่มีประโยชน์สำหรับการกำหนดค่า
- --prefix=$HOME: เปลี่ยนตำแหน่งการติดตั้งเริ่มต้น (ซึ่งโดยปกติคือ /usr/local/) ให้เป็นไดเรกทอรี home ของคุณ หรือเส้นทางที่คุณต้องการ
- --disable-wallet: ใช้เพื่อปิดการใช้งานฟังก์ชัน wallet แบบอ้างอิง
- --with-incompatible-bdb: หากคุณกำลังสร้าง wallet ให้ยอมรับการใช้ไลบรารี Berkeley DB เวอร์ชันที่ไม่เข้ากันได้
- --with-gui=no: ไม่สร้างส่วนติดต่อผู้ใช้แบบกราฟิก (GUI) ซึ่งต้องใช้ไลบรารี Qt โดยตัวเลือกนี้จะสร้างเฉพาะเซิร์ฟเวอร์และ Bitcoin Core แบบ commandline เท่านั้น
```
ต่อไป ให้รันสคริปต์ configure เพื่อให้ระบบตรวจสอบไลบรารีที่จำเป็นทั้งหมดและสร้างสคริปต์สำหรับการสร้างที่ปรับแต่งให้ตรงกับระบบของคุณ:
$ ./configure checking for pkg-config... /usr/bin/pkg-config checking pkg-config is at least version 0.9.0... yes checking build system type... x86_64-pc-linux-gnu checking host system type... x86_64-pc-linux-gnu checking for a BSD-compatible install... /usr/bin/install -c ... [many pages of configuration tests follow] ... ```หากทุกอย่างดำเนินไปด้วยดี คำสั่ง configure จะสิ้นสุดด้วยการสร้างสคริปต์การสร้างที่ปรับแต่งให้กับระบบของคุณ แต่หากมีไลบรารีที่หายไปหรือเกิดข้อผิดพลาด คำสั่ง configure จะหยุดและแสดงข้อผิดพลาดแทนที่จะสร้างสคริปต์ในกรณีที่เกิดข้อผิดพลาดขึ้น สาเหตุที่พบบ่อยคือการขาดหายหรือความไม่เข้ากันของไลบรารี ให้ตรวจสอบเอกสารการสร้างอีกครั้งและติดตั้ง pre-requisite ที่ขาดไป จากนั้นรัน configure อีกครั้งเพื่อดูว่าปัญหานั้นได้รับการแก้ไขแล้วหรือไม่
การสร้าง Executable ของ Bitcoin Core
ต่อไป คุณจะทำการคอมไพล์ซอร์สโค้ด กระบวนการนี้อาจใช้เวลาถึงหนึ่งชั่วโมง ขึ้นอยู่กับความเร็วของ CPU และหน่วยความจำที่มีอยู่ หากเกิดข้อผิดพลาด หรือการคอมไพล์ถูกขัดจังหวะ คุณสามารถดำเนินการต่อได้โดยการพิมพ์คำสั่ง make อีกครั้ง
พิมพ์ make เพื่อเริ่มคอมไพล์แอปพลิเคชันที่สามารถรันได้: ``` $ make Making all in src CXX bitcoind-bitcoind.o CXX libbitcoin_node_a-addrdb.o CXX libbitcoin_node_a-addrman.o CXX libbitcoin_node_a-banman.o CXX libbitcoin_node_a-blockencodings.o CXX libbitcoin_node_a-blockfilter.o [... many more compilation messages follow ...]
```
บนระบบที่มีความเร็วและมี CPU หลายคอร์ คุณอาจต้องการตั้งค่าจำนวนงานคอมไพล์แบบขนาน (parallel compile jobs) เช่น การใช้คำสั่ง make -j 2 จะใช้สองคอร์หากมีอยู่ หากทุกอย่างดำเนินไปด้วยดี Bitcoin Core จะถูกคอมไพล์เรียบร้อยแล้ว คุณควรรันชุดการทดสอบหน่วย (unit test suite) ด้วยคำสั่ง make check เพื่อให้แน่ใจว่าไลบรารีที่ลิงค์เข้าด้วยกันไม่มีข้อผิดพลาดอย่าง ขั้นตอนสุดท้ายคือการติดตั้ง executable ต่าง ๆ ลงในระบบของคุณโดยใช้คำสั่ง make install ซึ่งอาจมีการร้องขอรหัสผ่านของผู้ใช้เนื่องจากขั้นตอนนี้ต้องการสิทธิ์ผู้ดูแลระบบ: ``` $ make check && sudo make install Password: Making install in src ../build-aux/install-sh -c -d '/usr/local/lib' libtool: install: /usr/bin/install -c bitcoind /usr/local/bin/bitcoind libtool: install: /usr/bin/install -c bitcoin-cli /usr/local/bin/bitcoin-cli libtool: install: /usr/bin/install -c bitcoin-tx /usr/local/bin/bitcoin-tx ...
```
การติดตั้งเริ่มต้นของ bitcoind จะอยู่ในไดเรกทอรี /usr/local/bin โดยคุณสามารถตรวจสอบว่า Bitcoin Core ถูกติดตั้งเรียบร้อยแล้วโดยใช้คำสั่งเพื่อตรวจสอบตำแหน่งของ executable ดังนี้:
$ which bitcoind /usr/local/bin/bitcoind $ which bitcoin-cli /usr/local/bin/bitcoin-cli
มาลองรัน Bitcoin node กันเถอะ
อย่างที่ได้กล่าวในบทก่อนหน้า เครือข่ายแบบเพียร์ทูเพียร์ของบิตคอยน์ประกอบด้วยเครือข่าย "โหนด" ซึ่งส่วนใหญ่รันโดยบุคคลและธุรกิจบางแห่งที่ให้บริการ ผู้ที่รันโหนดบิตคอยน์จะมีมุมมองที่ตรงและน่าเชื่อถือเกี่ยวกับบล๊อกเชนของบิตคอยน์พร้อมสำเนาข้อมูลบิตคอยน์ที่ใช้จ่ายได้ทั้งหมดซึ่งได้รับการตรวจสอบอย่างอิสระโดยระบบของตนเอง การรันโหนดทำให้คุณไม่ต้องพึ่งบุคคลที่สามในการตรวจสอบธุรกรรม นอกจากนี้การใช้โหนดบิตคอยน์เพื่อตรวจสอบธุรกรรมที่ได้รับในกระเป๋าเงินของคุณ ยังช่วยให้คุณมีส่วนร่วมในเครือข่ายบิตคอยน์และช่วยทำให้เครือข่ายมีความแข็งแกร่งมากขึ้นอีกด้วย
การรันโหนดต้องดาวน์โหลดและประมวลผลข้อมูลมากกว่า 500 GB ในช่วงเริ่มแรก และประมาณ 400 MB ของธุรกรรม Bitcoin ต่อวัน ตัวเลขเหล่านี้เป็นของปี 2023 และอาจเพิ่มขึ้นในอนาคต หากคุณปิดโหนดหรือหลุดจากอินเทอร์เน็ตเป็นเวลาหลายวัน โหนดของคุณจะต้องดาวน์โหลดข้อมูลที่พลาดไป ตัวอย่างเช่น หากคุณปิด Bitcoin Core เป็นเวลา 10 วัน คุณจะต้องดาวน์โหลดประมาณ 4 GB ในครั้งถัดไปที่คุณเริ่มใช้งาน
ขึ้นอยู่กับการเลือกของคุณว่าจะทำดัชนีธุรกรรมทั้งหมดและเก็บสำเนาบล๊อกเชนแบบเต็ม คุณอาจต้องใช้พื้นที่ดิสก์มาก - อย่างน้อย 1 TB หากคุณวางแผนจะรัน Bitcoin Core เป็นเวลาหลายปี โดยค่าเริ่มต้นโหนดบิตคอยน์ยังส่งธุรกรรมและบล็อกไปยังโหนดอื่น ๆ (เรียกว่า "เพียร์") ซึ่งจะใช้แบนด์วิดท์อัปโหลดอินเทอร์เน็ต หากการเชื่อมต่ออินเทอร์เน็ตของคุณมีขีดจำกัด มีขีดจำกัดการใช้ข้อมูลต่ำ หรือคิดค่าบริการตามข้อมูล (เมตเตอร์) คุณไม่ควรรันโหนดบิตคอยน์บนระบบนั้น หรือรันโดยจำกัดแบนด์วิดท์ (ดู การกำหนดค่าโหนด Bitcoin Core) คุณอาจเชื่อมต่อโหนดของคุณแทนไปยังเครือข่ายทางเลือก เช่น ผู้ให้บริการข้อมูลดาวเทียมฟรีอย่าง Blockstream Satellite
Tip: Bitcoin Core เก็บสำเนาบล๊อกเชนแบบเต็ม (ตามค่าเริ่มต้น ) พร้อมธุรกรรมเกือบทั้งหมดที่เคยได้รับการยืนยันบนเครือข่าย Bitcoin ตั้งแต่เริ่มต้นในปี 2009 ชุดข้อมูลนี้มีขนาดหลายร้อย GB และจะถูกดาวน์โหลดเพิ่มขึ้นทีละน้อยในช่วงหลายชั่วโมงหรือหลายวัน ขึ้นอยู่กับความเร็ว CPU และการเชื่อมต่ออินเทอร์เน็ตของคุณ Bitcoin Core จะไม่สามารถประมวลผลธุรกรรมหรืออัปเดตยอดคงเหลือของบัญชีจนกว่าชุดข้อมูล blockchain จะดาวน์โหลดเสร็จสมบูรณ์ ตรวจสอบให้แน่ใจว่าคุณมีพื้นที่ดิสก์ แบนด์วิดท์ และเวลาเพียงพอในการซิงโครไนซ์เริ่มแรก คุณสามารถกำหนดค่า Bitcoin Core เพื่อลดขนาด blockchain โดยการทิ้งบล็อกเก่า แต่โปรแกรมยังคงดาวน์โหลดชุดข้อมูลทั้งหมด
TIPจากหลาม agian: ซื้อ NVMe SSD 2TB เป็นอย่างต่ำซ่ะ m.2 ได้ยิ่งดีเลยจ้า
แม้ว่าจะมีข้อกำหนดด้านทรัพยากรเหล่านี้ แต่มีผู้คนหลายพันรายที่รันโหนด Bitcoin บางคนรันบนระบบง่าย ๆ อย่าง Raspberry Pi (คอมพิวเตอร์ราคา 35 เหรียญสหรัฐที่มีขนาดเท่ากับกล่องบุหรี่)
ทำไมคุณถึงอยากรันโหนด? นี่คือเหตุผลที่พบบ่อยที่สุด:
- คุณไม่ต้องการพึ่งบุคคลที่สามในการตรวจสอบธุรกรรมที่คุณได้รับ
- คุณไม่ต้องการเปิดเผยให้บุคคลที่สามรู้ว่าธุรกรรมใดเป็นของกระเป๋าเงินคุณ
- คุณกำลังพัฒนาซอฟต์แวร์ Bitcoin และต้องการพึ่งโหนด Bitcoin เพื่อเข้าถึงเครือข่ายและ blockchain ผ่าน API
- คุณกำลังสร้างแอปพลิเคชันที่ต้องตรวจสอบธุรกรรมตามกฎฉันทามติของ Bitcoin โดยทั่วไป บริษัทซอฟต์แวร์ Bitcoin มักจะรันโหนดหลายโหนด
- คุณต้องการสนับสนุน Bitcoin การรันโหนดที่คุณใช้ตรวจสอบธุรกรรมที่ได้รับในกระเป๋าเงินจะช่วยทำให้เครือข่ายมีความแข็งแกร่งมากขึ้น
หากคุณกำลังอ่านหนังสือเล่มนี้และสนใจความปลอดภัยที่เข้มงวด ความเป็นส่วนตัวที่เหนือกว่า หรือการพัฒนาซอฟต์แวร์ Bitcoin คุณควรรันโหนดของตัวเอง
การกำหนดค่าโหนด Bitcoin Core
Bitcoin Core จะค้นหาไฟล์การกำหนดค่าในไดเรกทอรีข้อมูลทุกครั้งที่เริ่มทำงาน ในส่วนนี้เราจะตรวจสอบตัวเลือกการกำหนดค่าต่าง ๆ และตั้งค่าไฟล์การกำหนดค่า
เพื่อค้นหาไฟล์การกำหนดค่า ให้รัน bitcoind -printtoconsole ในเทอร์มินัลของคุณ และดูบรรทัดแรก ๆ:
$ bitcoind -printtoconsole 2023-01-28T03:21:42Z Bitcoin Core version v24.0.1 2023-01-28T03:21:42Z Using the 'x86_shani(1way,2way)' SHA256 implementation 2023-01-28T03:21:42Z Using RdSeed as an additional entropy source 2023-01-28T03:21:42Z Using RdRand as an additional entropy source 2023-01-28T03:21:42Z Default data directory /home/harding/.bitcoin 2023-01-28T03:21:42Z Using data directory /home/harding/.bitcoin 2023-01-28T03:21:42Z Config file: /home/harding/.bitcoin/bitcoin.conf ... [a lot more debug output] ...
tatatipจากหลามอีกครั้ง: สังเกตเห็นหรือไม่ว่าในตัวอย่างนี้ Bitcoin Core กำลังชี้ไปที่ไฟล์การกำหนดค่าที่ไดเรกทอรี /home/harding/.bitcoin/bitcoin.conf ซึ่งจะแตกต่างกันไปขึ้นอยู่กับผู้ใช้และระบบปฏิบัติการ
คุณสามารถกด Ctrl-C เพื่อปิดโหนดหลังจากที่ระบุตำแหน่งไฟล์การกำหนดค่า โดยปกติไฟล์การกำหนดค่าจะอยู่ในไดเรกทอรี .bitcoin ภายใต้โฮมไดเรกทอรีของผู้ใช้ เปิดไฟล์ configuration ด้วยโปรแกรมแก้ไขได้ตามที่คุณชอบ
Bitcoin Core มีตัวเลือกการกำหนดค่ามากกว่า 100 ตัวเลือกที่สามารถปรับเปลี่ยนพฤติกรรมของโหนดเครือข่าย การจัดเก็บบล๊อกเชน และแง่มุมอื่น ๆ ของการทำงาน เพื่อดูรายการตัวเลือก ให้รัน bitcoind --help:
$ bitcoind --help Bitcoin Core version v24.0.1 Usage: bitcoind [options] Start Bitcoin Core Options: -? Print this help message and exit -alertnotify=<cmd> Execute command when an alert is raised (%s in cmd is replaced by message) ... [many more options]
นี่คือตัวเลือกที่บางประการที่คุณสามารถตั้งในไฟล์ configuration หรือเป็นพารามิเตอร์บรรทัดคำสั่งสำหรับ bitcoind:
- alertnotify: เรียกใช้คำสั่งหรือสคริปต์เพื่อส่งการแจ้งเตือนฉุกเฉินไปยังเจ้าของโหนดนี้
- conf: ตำแหน่งทางเลือกสำหรับไฟล์ configuration เมื่อใช้เป็นพารามิเตอร์ cli สำหรับ bitcoind เท่านั้น เนื่องจากไม่สามารถอยู่ในไฟล์ configuration ที่มันอ้างถึงได้
- datadir: เลือกไดเรกทอรีและระบบไฟล์สำหรับจัดเก็บข้อมูลบล๊อกเชนตามค่าเริ่มต้นนี้คือไดเรกทอรีย่อย .bitcoin ในไดเรกทอรีโฮมของคุณ ขึ้นอยู่กับการกำหนดค่า สามารถใช้พื้นที่ตั้งแต่ประมาณ 10 GB ถึงเกือบ 1 TB ณ ขณะนี้ คาดว่าขนาดสูงสุดจะเพิ่มขึ้นหลายร้อย GB ต่อปี
- prune: ลดความต้องการพื้นที่ดิสก์บล๊อกเชนลงเหลือกี่เมกะไบต์โดยการลบบล็อกเก่า ใช้สำหรับโหนดที่มีทรัพยากรจำกัดซึ่งไม่สามารถบรรจุบล๊อกเชนแบบเต็มได้ ส่วนอื่น ๆ ของระบบจะใช้พื้นที่ดิสก์อื่นที่ไม่สามารถตัดทอนได้ ดังนั้นคุณยังคงต้องมีพื้นที่อย่างน้อยตามที่ระบุในตัวเลือก datadir

ดัชนีฐานข้อมูลธุรกรรมและตัวเลือก txindex
ตามค่าเริ่มต้น Bitcoin Core จะสร้างฐานข้อมูลที่มีเพียงธุรกรรมที่เกี่ยวข้องกับกระเป๋าเงินของผู้ใช้เท่านั้น หากคุณต้องการสามารถเข้าถึงธุรกรรมใด ๆ ด้วยคำสั่งเช่น getrawtransaction คุณจะต้องกำหนดค่า Bitcoin Core ให้สร้างดัชนีธุรกรรมแบบสมบูรณ์ ซึ่งสามารถทำได้ด้วยตัวเลือก txindex โดยตั้ง txindex=1 ในไฟล์การกำหนดค่า Bitcoin Core หากคุณไม่ได้ตั้งตัวเลือกนี้ตั้งแต่แรกและต่อมาตั้งเป็นการทำดัชนีแบบเต็ม คุณจะต้องรอให้มันสร้างดัชนีใหม่
ตัวอย่างการกำหนดค่าโหนดดัชนีแบบเต็มแสดงวิธีที่คุณอาจรวมตัวเลือกก่อนหน้านี้กับโหนดที่มีดัชนีแบบเต็ม โดยทำงานเป็นแบ็กเอนด์ API สำหรับแอปพลิเคชัน bitcoin
ตัวอย่างที่ 1. การกำหนดค่าโหนดดัชนีแบบเต็ม
alertnotify=myemailscript.sh "Alert: %s" datadir=/lotsofspace/bitcoin txindex=1
ตัวอย่างที่ 2. การกำหนดค่าระบบที่มีทรัพยากรจำกัด
alertnotify=myemailscript.sh "Alert: %s" blocksonly=1 prune=5000 dbcache=150 maxmempool=150
หลังจากที่คุณแก้ไขไฟล์การกำหนดค่าและตั้งตัวเลือกที่ดีที่สุดตามความต้องการของคุณ คุณสามารถทดสอบ bitcoind ด้วยการกำหนดค่านี้ รัน Bitcoin Core ด้วยตัวเลือก printtoconsole เพื่อรันที่ foreground พร้อมแสดงผลลัพธ์ที่คอนโซล:

คุณสามารถกด Ctrl-C เพื่อหยุดกระบวนการเมื่อคุณพอใจว่ากำลังโหลดการตั้งค่าที่ถูกต้องและทำงานตามที่คาดหวัง
เพื่อรัน Bitcoin Core ที่พื้นหลังเป็นโพรเซส ให้เริ่มด้วยตัวเลือก daemon เช่น bitcoind -daemon
เพื่อตรวจสอบความคืบหน้าและสถานะการทำงานของโหนด Bitcoin ให้เริ่มในโหมด daemon แล้วใช้คำสั่ง bitcoin-cli getblockchaininfo:
``` $ bitcoin-cli getblockchaininfo
{ "chain": "main", "blocks": 0, "headers": 83999, "bestblockhash": "[...]19d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f", "difficulty": 1, "time": 1673379796, "mediantime": 1231006505, "verificationprogress": 3.783041623201835e-09, "initialblockdownload": true, "chainwork": "[...]000000000000000000000000000000000000000000000100010001", "size_on_disk": 89087, "pruned": false, "warnings": "" }
```
นี่แสดงโหนดที่มีความสูงของ blockchain เป็น 0 บล็อก และ 83,999 เฮดเดอร์ โหนดจะดึงเฮดเดอร์ของบล็อกจากเพียร์ของตนก่อนเพื่อค้นหา blockchain ที่มีหลักฐานการทำงานมากที่สุด จากนั้นจึงดำเนินการดาวน์โหลดบล็อกเต็มโดยตรวจสอบความถูกต้องไปพร้อมกัน
เมื่อคุณพอใจกับตัวเลือกการกำหนดค่าที่เลือก คุณควรเพิ่ม Bitcoin Core ลงในสคริปต์เริ่มต้นของระบบปฏิบัติการ เพื่อให้มันทำงานอย่างต่อเนื่องและรีสตาร์ทเมื่อระบบปฏิบัติการรีสตาร์ท คุณจะพบสคริปต์เริ่มต้นตัวอย่างสำหรับระบบปฏิบัติการต่าง ๆ ในไดเรกทอรีซอร์สของ Bitcoin Core ภายใต้ contrib/init และไฟล์ README.md ที่แสดงว่าระบบใดใช้สคริปต์ใด
Bitcoin Core API
Bitcoin Core ใช้อินเทอร์เฟซ JSON-RPC ซึ่งสามารถเข้าถึงได้โดยใช้เครื่องมืออย่าง bitcoin-cli ซึ่งช่วยให้เราสามารถทดลองใช้งานความสามารถต่างๆ แบบโต้ตอบได้ ซึ่งความสามารถเหล่านี้ยังสามารถใช้งานได้ผ่านทาง API ในรูปแบบโปรแกรม เพื่อเริ่มต้น ให้เรียกใช้คำสั่ง help เพื่อดูรายการคำสั่ง Bitcoin Core RPC ที่มีอยู่:
$ bitcoin-cli help +== Blockchain == getbestblockhash getblock "blockhash" ( verbosity ) getblockchaininfo ... walletpassphrase "passphrase" timeout walletpassphrasechange "oldpassphrase" "newpassphrase" walletprocesspsbt "psbt" ( sign "sighashtype" bip32derivs finalize )
คำสั่งแต่ละรายการอาจต้องการพารามิเตอร์หลายตัว เพื่อรับความช่วยเหลือเพิ่มเติม คำอธิบายโดยละเอียด และข้อมูลเกี่ยวกับพารามิเตอร์ต่างๆ ให้เพิ่มชื่อคำสั่งหลังคำว่า help ตัวอย่างเช่น เพื่อดูความช่วยเหลือเกี่ยวกับคำสั่ง RPC getblockhash: ``` $ bitcoin-cli help getblockhash getblockhash height Returns hash of block in best-block-chain at height provided. Arguments: 1. height (numeric, required) The height index Result: "hex" (string) The block hash Examples:
bitcoin-cli getblockhash 1000 curl --user myusername --data-binary '{"jsonrpc": "1.0", "id": "curltest", "method": "getblockhash", "params": [1000]}' -H 'content-type: text/plain;' http://127.0.0.1:8332/ ``` ในส่วนท้ายของข้อมูลคำสั่ง help คุณจะเห็นตัวอย่างสองตัวอย่างของคำสั่ง RPC ซึ่งใช้ตัวช่วย bitcoin-cli หรือ HTTP client curl ตัวอย่างเหล่านี้แสดงให้เห็นว่าคุณอาจเรียกใช้คำสั่งได้อย่างไร ลองคัดลอกตัวอย่างแรกและดูผลลัพธ์:
$ bitcoin-cli getblockhash 1000 00000000c937983704a73af28acdec37b049d214adbda81d7e2a3dd146f6ed09
ผลลัพธ์คือแฮชของบล็อก ซึ่งจะอธิบายในรายละเอียดเพิ่มเติมในบทต่อไป แต่ในตอนนี้ คำสั่งนี้ควรให้ผลลัพธ์เหมือนกันบนระบบของคุณ ซึ่งแสดงให้เห็นว่าโหนด Bitcoin Core ของคุณกำลังทำงาน กำลังรับคำสั่ง และมีข้อมูลเกี่ยวกับบล็อก 1,000 ที่จะส่งกลับมาให้คุณ
การรับข้อมูลสถานะของ Bitcoin Core
Bitcoin Core ให้รายงานสถานะเกี่ยวกับโมดูลต่างๆ ผ่านอินเตอร์เฟส JSON-RPC คำสั่งที่สำคัญที่สุดรวมถึง getblockchaininfo, getmempoolinfo, getnetworkinfo และ getwalletinfo
คำสั่ง RPC getblockchaininfo ของ Bitcoin ได้ถูกแนะนำไปก่อนหน้านี้แล้ว คำสั่ง getnetworkinfo แสดงข้อมูลพื้นฐานเกี่ยวกับสถานะของโหนดเครือข่าย Bitcoin ใช้ bitcoin-cli เพื่อรันคำสั่งนี้:
$ bitcoin-cli getnetworkinfo { "version": 240001, "subversion": "/Satoshi:24.0.1/", "protocolversion": 70016, "localservices": "0000000000000409", "localservicesnames": [ "NETWORK", "WITNESS", "NETWORK_LIMITED" ], "localrelay": true, "timeoffset": -1, "networkactive": true, "connections": 10, "connections_in": 0, "connections_out": 10, "networks": [ "...detailed information about all networks..." ], "relayfee": 0.00001000, "incrementalfee": 0.00001000, "localaddresses": [ ], "warnings": "" }
ซึ่งข้อมูลต่าง ๆ จะถูกส่งคืนในรูปแบบ JavaScript Object Notation (JSON) ซึ่งเป็นรูปแบบที่สามารถ "อ่าน" ได้อย่างง่ายดายโดยทุกภาษาโปรแกรมมิ่ง และยังเป็นรูปแบบที่มนุษย์อ่านได้ง่ายอีกด้วย ในข้อมูลนี้เราเห็นหมายเลขเวอร์ชันสำหรับซอฟต์แวร์ Bitcoin Core และโปรโตคอลบิตคอยน์เราเห็นจำนวนการเชื่อมต่อในปัจจุบันและข้อมูลต่างๆ เกี่ยวกับเครือข่ายบิตคอยน์และการตั้งค่าที่เกี่ยวข้องกับโหนดนี้
TIP: จะใช้เวลาสักระยะ อาจมากกว่าหนึ่งวัน สำหรับ bitcoind ในการอัพเดทให้ทันกับบล็อกล่าสุดของบล็อกเชนปัจจุบัน ในขณะที่มันดาวน์โหลดบล็อกจากโหนดอื่นๆ และตรวจสอบความถูกต้องของทุกธุรกรรมในบล็อกเหล่านั้น—ซึ่งมีเกือบหนึ่งพันล้านธุรกรรม ณ เวลาที่เขียนนี้ คุณสามารถตรวจสอบความคืบหน้าโดยใช้ getblockchaininfo เพื่อดูจำนวนบล็อกที่ทราบ ตัวอย่างในส่วนที่เหลือของบทนี้สมมติว่าคุณอยู่อย่างน้อยที่บล็อก 775,072 เนื่องจากความปลอดภัยของธุรกรรมขึ้นอยู่กับจำ
มาสำรวจและถอดรหัสธุรกรรมของบิตคอยน์กันเถอะ!!
อย่างในบทที่สอง อลิซได้ซื้อสินค้าจากร้านของบ็อบและธุรกรรมของเธอถูกบันทึกลงในบล็อกเชนของบิตคอยน์ โดยเราสามารถใช้ API เพื่อดึงและตรวจสอบธุรกรรมนั้นได้โดยการใช้ txid เป็นพารามิเตอร์:
$ bitcoin-cli getrawtransaction 466200308696215bbc949d5141a49a4138ecdfdfaa2a8029c1f9bcecd1f96177 --ผลลัพธ์ของคำสั่ง 01000000000101eb3ae38f27191aa5f3850dc9cad00492b88b72404f9da13569 8679268041c54a0100000000ffffffff02204e0000000000002251203b41daba 4c9ace578369740f15e5ec880c28279ee7f51b07dca69c7061e07068f8240100 000000001600147752c165ea7be772b2c0acb7f4d6047ae6f4768e0141cf5efe 2d8ef13ed0af21d4f4cb82422d6252d70324f6f4576b727b7d918e521c00b51b e739df2f899c49dc267c0ad280aca6dab0d2fa2b42a45182fc83e81713010000 0000
TIP: txid ไม่ใช่สิ่งที่สามารถเชื่อถือได้ขนาดนั้น เพราะการไม่มี txid ในบล๊อกเชนของบิตคอยน์นั้นไม่ได้หมายความว่าธุรกรรมไม่ได้ถูกประมวลผล โดยสิ่งนี้เรียกว่า "transaction malleability" (ความสามารถในการเปลี่ยนแปลงธุรกรรม) เพราะธุรกรรมสามารถถูกแก้ไขก่อนการยืนยันในบล็อก ซึ่งเปลี่ยน txid ของพวกมัน หลังจากธุรกรรมถูกรวมอยู่ในบล็อกแล้ว txid ของมันไม่สามารถเปลี่ยนแปลงได้อีก เว้นแต่จะมีการจัดระเบียบบล็อกเชนใหม่และบล็อกนั้นถูกลบออกจากบล็อกเชนที่ดีที่สุด โดยการจัดระเบียบใหม่เกิดขึ้นได้ยากหลังจากธุรกรรมได้รับการยืนยันหลายครั้งแล้ว
คำสั่ง getrawtransaction จะส่งคืนธุรกรรมที่เข้ารหัสในรูปแบบเลขฐานสิบหกและเพื่อถอดรหัสนั้น เราใช้คำสั่ง decoderawtransaction โดยส่งข้อมูลเลขฐานสิบหกเป็นพารามิเตอร์ คุณสามารถคัดลอกเลขฐานสิบหกที่ส่งคืนโดย getrawtransaction และวางเป็นพารามิเตอร์ให้กับ decoderawtransaction ได้:
$ bitcoin-cli decoderawtransaction 01000000000101eb3ae38f27191aa5f3850dc9cad00492b88b72404f9da135698679268041c54a0100000000ffffffff02204e0000000000002251203b41daba4c9ace578369740f15e5ec880c28279ee7f51b07dca69c7061e07068f8240100000000001600147752c165ea7be772b2c0acb7f4d6047ae6f4768e0141cf5efe2d8ef13ed0af21d4f4cb82422d6252d70324f6f4576b727b7d918e521c00b51be739df2f899c49dc267c0ad280aca6dab0d2fa2b42a45182fc83e817130100000000 --ผลลัพธ์ของคำสั่ง { "txid": "466200308696215bbc949d5141a49a4138ecdfdfaa2a8029c1f9bcecd1f96177", "hash": "f7cdbc7cf8b910d35cc69962e791138624e4eae7901010a6da4c02e7d238cdac", "version": 1, "size": 194, "vsize": 143, "weight": 569, "locktime": 0, "vin": [ { "txid": "4ac541802679866935a19d4f40728bb89204d0cac90d85f3a51a19...aeb", "vout": 1, "scriptSig": { "asm": "", "hex": "" }, "txinwitness": [ "cf5efe2d8ef13ed0af21d4f4cb82422d6252d70324f6f4576b727b7d918e5...301" ], "sequence": 4294967295 } ], "vout": [ { "value": 0.00020000, "n": 0, "scriptPubKey": { "asm": "1 3b41daba4c9ace578369740f15e5ec880c28279ee7f51b07dca...068", "desc": "rawtr(3b41daba4c9ace578369740f15e5ec880c28279ee7f51b...6ev", "hex": "51203b41daba4c9ace578369740f15e5ec880c28279ee7f51b07d...068", "address": "bc1p8dqa4wjvnt890qmfws83te0v3qxzsfu7ul63kp7u56w8q...5qn", "type": "witness_v1_taproot" } }, { "value": 0.00075000, "n": 1, "scriptPubKey": { "asm": "0 7752c165ea7be772b2c0acb7f4d6047ae6f4768e", "desc": "addr(bc1qwafvze0200nh9vkq4jmlf4sy0tn0ga5w0zpkpg)#qq404gts", "hex": "00147752c165ea7be772b2c0acb7f4d6047ae6f4768e", "address": "bc1qwafvze0200nh9vkq4jmlf4sy0tn0ga5w0zpkpg", "type": "witness_v0_keyhash" } } ] }
การถอดรหัสธุรกรรมแสดงส่วนประกอบทั้งหมดของธุรกรรมนี้ รวมถึงอินพุตและเอาต์พุตของธุรกรรม ในกรณีนี้เราเห็นว่าธุรกรรมใช้อินพุตหนึ่งรายการและสร้างเอาต์พุตสองรายการ อินพุตของธุรกรรมนี้คือเอาต์พุตจากธุรกรรมที่ได้รับการยืนยันก่อนหน้านี้ (แสดงเป็น txid ของอินพุต) เอาต์พุตทั้งสองรายการสอดคล้องกับการชำระเงินให้บ็อบและเงินทอนกลับให้อลิซ
มาสำรวจบล็อกของบิตคอยน์กัน!!
การสำรวจบล็อกนั้นคล้ายกับการสำรวจธุรกรรม แต่อย่างไรก็ตามบล็อกสามารถอ้างอิงได้ทั้งโดยลำดับของบล็อกหรือโดยแฮชของบล็อก เราใช้คำสั่ง getblockhash ซึ่งรับลำดับของบล็อกเป็นพารามิเตอร์และส่งคืน แฮชของบล็อกนั้น:
$ bitcoin-cli getblockhash 123456 --ผลลัพธ์ของคำสั่ง 0000000000002917ed80650c6174aac8dfc46f5fe36480aaef682ff6cd83c3ca
ตอนนี้เรารู้แฮชสำหรับบล็อกที่เราเลือกแล้ว เราสามารถดูบล็อกนั้นได้ เราใช้คำสั่ง getblock โดยมีแฮชของบล็อกเป็นพารามิเตอร์:$ bitcoin-cli getblockhash 0000000000002917ed80650c6174aac8dfc46f5fe36480aaef682ff6cd83c3ca --ผลลัพธ์ของคำสั่ง { "hash": "0000000000002917ed80650c6174aac8dfc46f5fe36480aaef682ff6cd83c3ca", "confirmations": 651742, "height": 123456, "version": 1, "versionHex": "00000001", "merkleroot": "0e60651a9934e8f0decd1c[...]48fca0cd1c84a21ddfde95033762d86c", "time": 1305200806, "mediantime": 1305197900, "nonce": 2436437219, "bits": "1a6a93b3", "difficulty": 157416.4018436489, "chainwork": "[...]00000000000000000000000000000000000000541788211ac227bc", "nTx": 13, "previousblockhash": "[...]60bc96a44724fd72daf9b92cf8ad00510b5224c6253ac40095", "nextblockhash": "[...]00129f5f02be247070bf7334d3753e4ddee502780c2acaecec6d66", "strippedsize": 4179, "size": 4179, "weight": 16716, "tx": [ "5b75086dafeede555fc8f9a810d8b10df57c46f9f176ccc3dd8d2fa20edd685b", "e3d0425ab346dd5b76f44c222a4bb5d16640a4247050ef82462ab17e229c83b4", "137d247eca8b99dee58e1e9232014183a5c5a9e338001a0109df32794cdcc92e", "5fd167f7b8c417e59106ef5acfe181b09d71b8353a61a55a2f01aa266af5412d", "60925f1948b71f429d514ead7ae7391e0edf965bf5a60331398dae24c6964774", "d4d5fc1529487527e9873256934dfb1e4cdcb39f4c0509577ca19bfad6c5d28f", "7b29d65e5018c56a33652085dbb13f2df39a1a9942bfe1f7e78e97919a6bdea2", "0b89e120efd0a4674c127a76ff5f7590ca304e6a064fbc51adffbd7ce3a3deef", "603f2044da9656084174cfb5812feaf510f862d3addcf70cacce3dc55dab446e", "9a4ed892b43a4df916a7a1213b78e83cd83f5695f635d535c94b2b65ffb144d3", "dda726e3dad9504dce5098dfab5064ecd4a7650bfe854bb2606da3152b60e427", "e46ea8b4d68719b65ead930f07f1f3804cb3701014f8e6d76c4bdbc390893b94", "864a102aeedf53dd9b2baab4eeb898c5083fde6141113e0606b664c41fe15e1f" ] }
รายการ confirmations บอกเราถึง ความลึก ของบล็อกนี้—มีกี่บล็อกที่ถูกสร้างทับบนบล็อกนี้ ซึ่งบ่งบอกถึงความยากในการเปลี่ยนแปลงธุรกรรมใดๆ ในบล็อกนี้ ลำดับบอกเราว่ามีกี่บล็อกที่มาก่อนหน้าบล็อกนี้ เราเห็นเวอร์ชันของบล็อก เวลาที่มันถูกสร้าง (ตามข้อมูลของนักขุด) เวลาเฉลี่ยของ 11 บล็อกที่มาก่อนหน้าบล็อกนี้ (การวัดเวลาที่นักขุดปลอมแปลงได้ยากกว่า) และขนาดของบล็อกในการวัดสามแบบต่างกัน (ขนาดดั้งเดิมที่ถูกลบข้อมูลบางส่วนออก, ขนาดเต็ม, และขนาดในหน่วยน้ำหนัก) เรายังเห็นฟิลด์บางอย่างที่ใช้สำหรับความปลอดภัยและหลักฐานการทำงาน (merkle root, nonce, bits, difficulty, และ chainwork) เราจะตรวจสอบสิ่งเหล่านี้โดยละเอียดในส่วนของการขุดในบทที่ 12การใช้อินเตอร์เฟสโปรแกรมของ Bitcoin Core
bitcoin-cli มีประโยชน์มากสำหรับการใช้งาน API ของ Bitcoin Core และการทดสอบฟังก์ชันต่าง ๆ แต่จุดประสงค์หลักของ API คือการเข้าถึงฟังก์ชันด้วยโปรแกรม ในส่วนนี้เราจะสาธิตการเข้าถึง Bitcoin Core จากโปรแกรมอื่น
API ของ Bitcoin Core เป็นอินเตอร์เฟส JSON-RPC โดย JSON เป็นวิธีที่สะดวกมากในการนำเสนอข้อมูลที่ทั้งมนุษย์และโปรแกรมสามารถอ่านได้ง่าย RPC ย่อมาจาก remote procedure call ซึ่งหมายความว่าเรากำลังเรียกใช้กระบวนการ (ฟังก์ชัน) ที่อยู่ห่างไกล (บนโหนด Bitcoin Core) ผ่านโปรโตคอลเครือข่าย ในกรณีนี้ โปรโตคอลเครือข่ายคือ HTTP
เมื่อเราใช้คำสั่ง bitcoin-cli เพื่อขอความช่วยเหลือเกี่ยวกับคำสั่ง มันแสดงตัวอย่างการใช้ curl ซึ่งเป็นไคลเอนต์ HTTP ทางคอมมานด์ไลน์ที่ยืดหยุ่น เพื่อสร้างคำเรียก JSON-RPC เหล่านี้:
$ curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getblockchaininfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/
คำสั่งนี้แสดงว่า curl ส่งคำขอ HTTP ไปยัง localhost (127.0.0.1) เชื่อมต่อกับพอร์ต RPC เริ่มต้นของ Bitcoin (8332) และส่งคำขอ jsonrpc โดยใช้เมธอดเป็น getblockchaininfo โดยใช้การเข้ารหัสแบบ text/plain
คุณอาจสังเกตว่า curl จะขอให้ส่งข้อมูลประจำตัวไปพร้อมกับคำขอ Bitcoin Core จะสร้างรหัสผ่านแบบสุ่มในแต่ละครั้งที่เริ่มต้นและวางไว้ในไดเรกทอรีข้อมูลภายใต้ชื่อ .cookie โดย bitcoin-cli สามารถอ่านไฟล์รหัสผ่านนี้โดยให้ไดเรกทอรีข้อมูล ในทำนองเดียวกัน คุณสามารถคัดลอกรหัสผ่านและส่งไปยัง curl (หรือตัวครอบ Bitcoin Core RPC ระดับสูงอื่น ๆ ) ตามที่เห็นในการใช้การตรวจสอบสิทธิ์แบบใช้คุกกี้กับ Bitcoin Core
ตัวอย่างที่ 3. การใช้การตรวจสอบสิทธิ์แบบใช้คุกกี้กับ Bitcoin Core
$ cat .bitcoin/.cookie __cookie__:17c9b71cef21b893e1a019f4bc071950c7942f49796ed061b274031b17b19cd0 $ curl --user __cookie__:17c9b71cef21b893e1a019f4bc071950c7942f49796ed061b274031b17b19cd0 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getblockchaininfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/ {"result":{"chain":"main","blocks":799278,"headers":799278, "bestblockhash":"000000000000000000018387c50988ec705a95d6f765b206b6629971e6978879", "difficulty":53911173001054.59,"time":1689703111,"mediantime":1689701260, "verificationprogress":0.9999979206082515,"initialblockdownload":false, "chainwork":"00000000000000000000000000000000000000004f3e111bf32bcb47f9dfad5b", "size_on_disk":563894577967,"pruned":false,"warnings":""},"error":null, "id":"curltest"}
นอกจากนี้คุณยังสามารถตั้งรหัสผ่านด้วยตัวเองใน ./share/rpcauth/rpcauth.py ภายในไดเรกทอรีของ Bitcoin Core
หากคุณกำลังใช้การเรียก JSON-RPC ในโปรแกรมของคุณเอง คุณสามารถใช้ไลบรารี HTTP ทั่วไปเพื่อสร้างการเรียกได้ คล้ายกับที่แสดงในตัวอย่าง curl ก่อนหน้านี้
อย่างไรก็ตาม มีไลบรารีในภาษาโปรแกรมยอดนิยมส่วนใหญ่ที่ "wrap" API ของ Bitcoin Core ในลักษณะที่ทำให้การใช้งานง่ายขึ้นมาก เราจะใช้ไลบรารี python-bitcoinlib เพื่อทำให้การเข้าถึง API นั้นง่ายขึ้น โดยไลบรารีนี้ไม่ได้เป็นส่วนหนึ่งของโครงการ Bitcoin Core และจำเป็นต้องติดตั้งด้วยวิธีปกติที่คุณติดตั้งไลบรารี Python โปรดจำไว้ว่า การใช้งานนี้ต้องมีอินสแตนซ์ Bitcoin Core ที่กำลังทำงานอยู่ ซึ่งจะถูกใช้เพื่อทำการเรียก JSON-RPC
ตัวอย่างสคริปต์ Python ใน " การทำงาน getblockchaininfo ผ่าน API JSON-RPC ของ Bitcoin Core" ซึ่งทำการเรียก getblockchaininfo อย่างง่ายและพิมพ์พารามิเตอร์ block จากข้อมูลที่ส่งคืนโดย Bitcoin Core
ตัวอย่างที่ 4. การทำงาน getblockchaininfo ผ่าน API JSON-RPC ของ Bitcoin Core ``` from bitcoin.rpc import RawProxy
Create a connection to local Bitcoin Core node
p = RawProxy()
Run the getblockchaininfo command, store the resulting data in info
info = p.getblockchaininfo()
Retrieve the 'blocks' element from the info
print(info['blocks']) --ผลลัพธ์ของคำสั่ง $ python rpc_example.py 773973 ``` มันบอกเราว่าโหนด Bitcoin Core ในเครื่องของเรามีกี่บล็อกในบล็อกเชนของมัน ซึ่งไม่ใช่ผลลัพธ์ที่น่าทึ่ง แต่มันแสดงการใช้งานพื้นฐานของไลบรารีในฐานะอินเตอร์เฟสที่ถูกทำให้ง่ายขึ้นสำหรับ API JSON-RPC ของ Bitcoin Core
ต่อไป เราจะใช้คำสั่ง getrawtransaction และ decodetransaction เพื่อดึงข้อมูลรายละเอียดของการชำระเงินจาก Alice ไปยัง Bob ในส่วนของการดึงข้อมูลธุรกรรมและการวนลูปเอาต์พุตของธุรกรรม เราจะดึงธุรกรรมของ Alice และแสดงรายการเอาต์พุตของธุรกรรม สำหรับแต่ละเอาต์พุต เราจะแสดงที่อยู่ผู้รับและมูลค่า โดยธุรกรรมของ Alice มีเอาต์พุตหนึ่งรายการที่จ่ายให้ Bob และอีกหนึ่งรายการเป็นเงินทอนกลับไปยัง Alice
ตัวอย่างที่ 5 การดึงข้อมูลธุรกรรมและการวนลูปเอาต์พุตของธุรกรรม ``` from bitcoin.rpc import RawProxy p = RawProxy()
Alice's transaction ID
txid = "466200308696215bbc949d5141a49a4138ecdfdfaa2a8029c1f9bcecd1f96177"
First, retrieve the raw transaction in hex
raw_tx = p.getrawtransaction(txid)
Decode the transaction hex into a JSON object
decoded_tx = p.decoderawtransaction(raw_tx)
Retrieve each of the outputs from the transaction
for output in decoded_tx['vout']: print(output['scriptPubKey']['address'], output['value']) --ผลลัพธ์ของคำสั่ง $ python rpc_transaction.py bc1p8dqa4wjvnt890qmfws83te0v3qxzsfu7ul63kp7u56w8qc0qwp5qv995qn 0.00020000 bc1qwafvze0200nh9vkq4jmlf4sy0tn0ga5w0zpkpg 0.00075000 ``` ตัวอย่างทั้งสองข้างต้นค่อนข้างง่าย คุณไม่จำเป็นต้องใช้โปรแกรมในการรันพวกมัน คุณสามารถใช้ตัวช่วย bitcoin-cli ได้ง่าย ๆ แต่อย่างไรก็ตาม ตัวอย่างถัดไปต้องใช้การเรียก RPC หลายร้อยครั้งและแสดงให้เห็นถึงการใช้อินเทอร์เฟซเชิงโปรแกรมได้ชัดเจนยิ่งขึ้น
ในส่วนของการดึงข้อมูลบล็อกและการรวมเอาต์พุตของทุกธุรกรรม เราจะเริ่มต้นด้วยการดึงข้อมูลบล็อก จากนั้นดึงข้อมูลธุรกรรมแต่ละรายการภายในบล็อกโดยอ้างอิงถึง ID ของแต่ละธุรกรรม ต่อมา เราจะวนลูปผ่านเอาต์พุตของแต่ละธุรกรรมและรวมมูลค่าทั้งหมด
ตัวอย่างที่ 6 การดึงข้อมูลบล็อกและการรวมเอาต์พุตของทุกธุรกรรม ``` from bitcoin.rpc import RawProxy p = RawProxy()
The block height where Alice's transaction was recorded
blockheight = 775072
Get the block hash of the block at the given height
blockhash = p.getblockhash(blockheight)
Retrieve the block by its hash
block = p.getblock(blockhash)
Element tx contains the list of all transaction IDs in the block
transactions = block['tx'] block_value = 0
Iterate through each transaction ID in the block
for txid in transactions: tx_value = 0 # Retrieve the raw transaction by ID raw_tx = p.getrawtransaction(txid) # Decode the transaction decoded_tx = p.decoderawtransaction(raw_tx) # Iterate through each output in the transaction for output in decoded_tx['vout']: # Add up the value of each output tx_value = tx_value + output['value'] # Add the value of this transaction to the total block_value = block_value + tx_value print("Total value in block: ", block_value) --ผลลัพธ์ของคำสั่ง $ python rpc_block.py Total value in block: 10322.07722534 ```
โค้ดตัวอย่างของเราคำนวณว่ามูลค่ารวมที่ถูกทำธุรกรรมในบล็อกนี้คือ 10,322.07722534 BTC (รวมถึงรางวัล 25 BTC และค่าธรรมเนียม 0.0909 BTC) ลองเปรียบเทียบกับจำนวนที่รายงานโดยเว็บไซต์สำรวจบล็อก (block explorer) โดยการค้นหาแฮชของบล็อกหรือเลขลำดับของบล็อก เครื่องมือสำรวจบล็อกบางตัวรายงานมูลค่ารวมโดยไม่รวมรางวัลและไม่รวมค่าธรรมเนียม ลองดูว่าคุณสามารถสังเกตเห็นความแตกต่างได้หรือไม่

2025-05-24 10:00:42Asia has emerged as a powerhouse for bitcoin adoption, with diverse countries across the region embracing the world’s leading digital currency in unique ways.
From institutional investors in Singapore to grassroots movements in Indonesia, the Asian bitcoin ecosystem presents a fascinating tapestry of innovation, regulation, and community-driven initiatives.
We dive deep into the current state of bitcoin adoption across key Asian markets, providing investors with actionable insights into this dynamic region.
The Numbers: Asia’s Bitcoin Dominance
As of early 2025, over 500 million people worldwide hold some form of digital currency, with bitcoin remaining the most widely adopted digital asset. Asia stands at the forefront of this adoption wave, with the Central & Southern Asia and Oceania (CSAO) region leading the world in digital currency adoption according to Chainalysis’s 2024 Global Crypto Adoption Index.
The statistics paint a compelling picture:
- Seven of the top 20 countries in global crypto adoption are located in the CSAO region.
- India and China together comprise almost half of the world’s digital currency user base.
- Japan’s digital currency market is expected to reach 19.43 million users by the end of 2025, with a penetration rate of 15.93%.
Behind these impressive numbers lies a complex ecosystem shaped by diverse factors including regulatory environments, technological infrastructure, economic necessities, and vibrant community initiatives.

Country-by-Country Analysis
India: The Grassroots Powerhouse
India ranks first in Chainalysis’s Global Crypto Adoption Index, with bitcoin adoption thriving particularly in tier-2 and tier-3 cities. This grassroots movement is driven primarily by:
- Financial inclusion: Bitcoin offers banking-like services to India’s large unbanked population.
- Remittance solutions: Lower fees for the significant Indian diaspora sending money home.
- Mobile wallet proliferation: India’s high smartphone penetration enables easy access to bitcoin services.
Japan: The Regulatory Pioneer
Japan has long played a significant role in bitcoin’s evolution, from hosting some of the earliest exchanges to pioneering regulatory clarity. In 2025, Japan finds itself at a fascinating crossroads:
- The Japan Financial Services Agency is considering reclassifying digital currency assets as financial products akin to stocks, potentially enhancing user protection.
- Major corporations like Metaplanet Inc. are expanding their bitcoin holdings, with plans to increase holdings by 470% to reach 10,000 BTC in 2025.
- The country boasts a thriving grassroots bitcoin community and a strong developer ecosystem.
Bitcoin adoption in Japan is uniquely balanced between institutional involvement and community enthusiasm, with initiatives like Blockstream’s Tokyo office working to promote layer-2 solutions, self-custody, and developer education.
Vietnam: The P2P Leader
Vietnam consistently ranks among the top countries for bitcoin adoption per capita. The country’s relationship with bitcoin is characterized by:
- Strong peer-to-peer (P2P) platform usage for daily transactions and remittances.
- High mobile wallet adoption driving grassroots usage.
- Bitcoin serving as a hedge against local currency fluctuations.
- Relatively favorable regulatory attitude compared to some neighboring countries.
Singapore: The Institutional Hub
Singapore has established itself as Asia’s premier institutional bitcoin destination through:
- Clear and forward-thinking regulatory frameworks, particularly the Payment Services Act.
- Growing presence of global digital currency firms including Gemini, OKX, and HashKey, which have received regulatory approvals.
- A robust financial infrastructure catering to high-net-worth individuals and institutional investors.
While Singapore’s consumer protection-focused framework restricts promotional activities and public advertising by digital currency service providers, the city-state remains a beacon for institutional bitcoin adoption in Asia.
South Korea: Retail Dominance Transitioning to Institutional
South Korea presents a fascinating case study of a market in transition:
- Retail investors currently dominate digital currency trading volume, while institutional participation significantly lags behind.
- Experts expect institutional involvement to increase, though a significant shift may not occur until around 2027.
- The local finance watchdog recently launched a crypto committee to assess permissions for corporate digital currency investors and ETFs.
- Users must access fiat-to-digital currency services through local exchanges with official banking partnerships, linking digital currency activities to legal identities.
Bitcoin Communities: The Grassroots Movements
What truly sets Asia apart in the global bitcoin landscape is the vibrant tapestry of community-driven initiatives across the region. These grassroots movements are instrumental in driving adoption from the ground up.
Bitcoin House Bali: A Community Hub
In Indonesia, the Bitcoin House Bali project exemplifies grassroots innovation. This initiative has transformed an old mining container into a vibrant hub for bitcoin education and community engagement.
Key features include:
- Free workshops (including “Bitcoin for Beginners” and “Bitcoin for Kids”).
- Developer programs including online classes, BitDevs Workshops, and Hackathons.
- A closed-loop economic system that turns bitcoin into community points.
- Merchant onboarding—from restaurants and drivers to scooter rentals and street vendors.
Bitcoin Seoul 2025: Bringing the Community Together
The upcoming Bitcoin Seoul 2025 conference (June 4-6, 2025) represents Asia’s largest bitcoin-focused gathering, bringing together global leaders, executives, and community members.
The event will feature:
- The Bitcoin Policy Summit: Seoul Edition, providing insights into regulatory trends.
- The Bitcoin Finance Forum, addressing institutional investment and treasury management.
- A Global Bitcoin Community Assembly for bitcoin grassroots and community leaders.
- Live Lightning Network payments demonstrations at the on-site Lightning Market.
This event underscores South Korea’s emerging role in the global Bitcoin ecosystem and highlights the growing institutional interest in the region.
Regulatory Landscapes: A Mixed Picture
The regulatory environment for bitcoin across Asia presents a complex and evolving picture that significantly impacts adoption patterns.
Japan’s Regulatory Evolution
Japan is considering tightening regulations on digital asset transactions by reclassifying them as financial products similar to stocks. If implemented, these changes would:
- Require issuers to disclose more detailed information on their corporate status.
- Potentially enhance user protection.
- Come into effect after June 2025, following policy direction outlines by the administration.
Current regulations in Japan are relatively digital currency-friendly, with bitcoin recognized as a legal form of payment under the Payment Services Act since 2016.
Singapore’s Balanced Approach
Singapore maintains a regulatory framework that emphasizes market stability and consumer protection, including:
- Restrictions on promoting digital services in public areas.
- The Payment Services Act that regulates digital currency exchanges.
- A general approach that supports institutional adoption while carefully managing retail exposure.
This balanced approach has helped establish Singapore as a trusted hub for bitcoin businesses and institutional investors.
South Korea’s Transitional Framework
South Korea’s regulatory landscape is in flux, with several developments impacting the bitcoin ecosystem:
- Corporate access to digital currenc

2025-03-08 02:28:40Libertarians believe in open borders in theory. In practice, open borders don’t work, because, among other things, the combination with a welfare state creates a moral hazard, and the least productive of society end up within the borders of welfare states and drain resources. The social services are paid by the productive people of the country or, in the case of most fiat systems, by currency holders through inflation. Welfare states are much more likely under fiat money and the redistribution goes from native taxpayers to illegal immigrants. Thus, under fiat money, open borders end up being an open wound by which the productive lifeblood of the country bleeds out, despite the theoretical trade-efficiency benefits. As libertarians like to say, open borders and the welfare state don’t mix. In this article, we’ll examine the other sacred cow of libertarian thought: free trade.
Free Trade without Libertarian Ideals
Free trade is very similar to free movement of labor in that it works great in theory, but not in practice, especially under fiat money. In a libertarian free-market world, free trade works. But that assumes a whole host of libertarian ideals like sound money, non-interfering governments, and minimal aggression. Once those ideals are violated, such as with government intervention in the market, similar moral hazards and long-term costs come with them, making free trade about as libertarian as a fractional reserve bank.
An example will illustrate what I’m talking about. Let’s say Portugal subsidizes their wine for export to other countries. The obvious first-order effect is that it makes Portuguese wine cheaper in France, perhaps undercutting the price of French wine. Libertarians would say, that’s great! French customers get cheaper goods, so what’s the problem?
As with any government intervention, there are significant second- and third-order effects in play. Subsidization puts unsubsidized companies at risk, perhaps driving them to bankruptcy. In this case, this might be a French wine maker. Subsidized companies may become zombies instead of dying out. In this case, this might be a Portuguese wine maker that was failing domestically but survives by selling to customers abroad with government subsidies. While French customers benefit in the short run with cheaper prices for wine, they are ultimately hurt because the goods that would have existed without government intervention never come to market. Perhaps French wine makers that went bankrupt were innovating. Perhaps the resources of the zombie Portuguese wine maker would have created something better.
Further, the dependency of French people on Portuguese wine means that something going wrong in Portugal, like a war or subsidy cuts, disrupts the supply and price of wine for France. Now France must meddle in Portugal internationally if it doesn’t want the wine supply to get disrupted. The two countries get entangled in such a way as to become more interventionist internationally. A war involving Portugal now suddenly becomes France’s business and incentivizes military aid or even violence. As usual, the unseen effects of government policy are the most pernicious.
Not Really Free
In other words, what we call free trade isn’t really free trade. A country exporting to the US may subsidize their products through government intervention, making the product cheaper in the US. This hurts US companies, and they’re forced into choices they never would have had to face without the foreign government intervention. But because the good is crossing borders under the rubric of “free trade,” it’s somehow seen as fair. Of course it’s not, as government intervention distorts the market whether it’s done by our own government or a foreign government.
So why would a foreign government do this? It gets several benefits through targeted market manipulation. First, it makes its own companies’ products more popular abroad and conversely, makes US companies’ products less popular. This has the dual benefit of growing the foreign government’s firms and shrinking, perhaps bankrupting, the US ones.
Targeted subsidization like this can lead to domination under free trade. It’s not unlike the Amazon strategy of undercutting everyone first and using the monopoly pricing power at scale once everyone else has bankrupted. The global monopoly is tremendously beneficial to the country that has it. Not only is there significant tax revenue over the long term, but also a head start on innovations within that industry and an advantage in production in the adjacent industries around the product.
Second, the manufacturing centralization gives that country leverage geo-politically. A critical product that no one else manufactures means natural alliances with the countries that depend on the product, which is especially useful for smaller countries like Taiwan. Their chip manufacturing industry, holding 60% of global supply (2024), has meant that they’re a critical link for most other countries, and hence, they can use this fact to deter Chinese invasion.
Third, because of the centralization of expertise, more innovations, products, and manufacturing will tend to come within the country. This increased production has cascading benefits, including new industries and national security. China leads the world in drone technology, which undoubtedly has given it an innovation advantage for its military, should it go to war.
Fourth, the capital that flows into the country for investing in the monopolized industry will tend to stay, giving the country more wealth in the form of factories, equipment, and skills. While that capital may nominally be in the hands of foreigners, over time, the ownership of that industry will inevitably transition toward native locals, as the knowledge about how to run such industries gets dissipated within the country.
Currency Devaluation: The Universal Trade Weapon
It would be one thing if only a specific industry were singled out for government subsidies and then the products dumped into the US as a way to hurt US companies, as that would limit the scope of the damage. But with currency devaluation, a government can subsidize all of its exports at the same time. Indeed, this is something that many countries do. While short-term, this helps US consumers, it hurts US companies and forces them into decisions that aren’t good for the US.
To compete, they have to lower costs by using the same devalued currency to pay their labor as their foreign competition. That is, by relocating their capital, their manufacturing, and even their personnel to the country that’s devaluing the currency. Not only does relocating reduce labor cost, but it also often gets them benefits like tax breaks. This makes US companies de facto multinationals and not only makes them subject to other jurisdictions, but ultimately divides their loyalties. To take advantage of the reduced labor, capital must move to another country and, along with it, future innovation.
Such relocations ultimately leave the company stripped of their manufacturing capability in the US, as local competition will generally fare better over the long run. Much of the value of the industry then is captured by other governments in taxes, development, and even state-owned companies. Free trade, in other words, creates a vulnerability for domestic companies as they can be put at a significant disadvantage compared to foreign counterparts.
Hidden Effects of Foreign Intervention
Unlike the multinationals, small companies have no chance as they’re not big enough to exploit the labor arbitrage. And as is usual in a fiat system, they suffer the most while the giant corporations get the benefits of the supposed “free trade”. Most small companies can’t compete, so we get mostly the bigger companies that survive.
The transition away from domestic manufacturing necessarily means significant disruption. Domestic workers are displaced and have to find new work. Factories and equipment either have to be repurposed or rot. Entire communities that depended on the manufacturing facility now have to figure out new ways to support themselves. It’s no good telling them that they can just do something else. In a currency devaluation scenario, most of the manufacturing leaves and the jobs left are service-oriented or otherwise location-based, like real estate development. There’s a natural limit to location-based industries because the market only grows with the location that you’re servicing. Put another way, you can only have so many people give haircuts or deliver packages in a geographic area. There has to be some manufacturing of goods that can be sold outside the community, or the community will face scarce labor opportunities relative to the population.
You also can’t say the displaced workers can start some other manufacturing business. Such businesses will get out-competed on labor by the currency-devaluing country, so there won’t be much investment available for such a business, and even if there were, such a business would be competing with its hands tied behind its back. So in this scenario, what you end up with are a large pool of unemployed people whom the state subsidizes with welfare.
So when a US company leaves or goes bankrupt due to a foreign government’s subsidies, the disruption alone imposes a significant short-term cost with displaced labor, unused capital goods, and devastated communities.
Mitigations
So how do countries fight back against such a devastating economic weapon? There are a few ways countries have found around this problem of currency devaluation under free trade. First, a country can prevent capital from leaving. This is called capital controls, and many countries, particularly those that manufacture a lot, have them. Try to get money, factories, or equipment out of Malaysia, for example, and you’ll find that they make it quite difficult. Getting the same capital into the country, on the other hand, faces few restrictions. Unfortunately, the US can’t put in capital controls because dollars are its main export. It is, after all, the reserve currency of the world.
Second, you can compete by devaluing your own currency. But that’s very difficult because it requires printing a lot of dollars, and that causes inflation. There’s also no guarantee that a competing country doesn’t devalue its currency again. The US is also in a precarious position as the world’s reserve currency, so devaluing the currency more than it already does will make other holders of the dollar less likely to want to hold it, threatening the reserve currency status.
So the main two mitigations against currency devaluation in a free trade scenario are not available to the US. So what else is there? The remaining option is to drop free trade. The solution, in other words, is to add tariffs. This is how you can nullify the effects of foreign government intervention, by leveling the playing field for US manufacturers.
Tariffs
One major industry that’s managed to continue being manufactured in the US despite significant foreign competition is cars. Notably, cars have a tariff, which incentivizes their manufacture in the US, even for foreign car makers. The tariff has acted as a way to offset foreign government subsidies and currency debasement.
The scope of this one industry for the US is huge. There are around 300,000 direct jobs in auto assembly within the US (USTR) and there are an additional 3 million jobs supplying these manufacturers within the US. But the benefits don’t end there. The US is also creating a lot of innovation around cars, such as self-driving and plug-in electric cars. There are many countries that would love to have this industry for themselves, but because of tariffs, auto manufacturing continues in the US.
And though tariffs are seen as a tax on consumers, US car prices are cheap relative to the rest of the world. What surprises a lot of people when they move from the US to other countries is finding out that the same car often costs more abroad (e.g. 25% tariffs keep U.S. prices 20% below Europe’s $40K average, 2024). The downside of tariffs pales next to the downsides of “free trade.”
Free Trade Doesn’t Work with Fiat Money
The sad reality is that while we would love for free trade to work in the ideal libertarian paradise, it won’t in our current fiat-based system. The subsidization by foreign governments to bankrupt US companies or to make them multinational, combined with the unfortunate reality of the US dollar being the world reserve currency, means that free trade guts the US of manufacturing. Tariffs are a reasonable way to protect US manufacturers, particularly smaller ones that can’t go multinational.
What’s more, tariffs make the US less fragile and less dependent on international supply chains. Many of the wars in the past 60 years have been waged because of the entanglements the US has with other countries due to the reliance on international supply chains. Lessening this dependency, if only to prevent a war, has clear value.
Lastly, labor has been devalued significantly by fiat monetary expansion, but at least some of that can be recovered if tariffs create more manufacturing, which in turn adds to the demand for labor. This should reduce the welfare state as more opportunities are made available and fewer unemployed people will be on the rolls.
Conclusion
Fiat money produces a welfare state, which makes open borders unworkable. Fiat money also gives foreign governments a potent economic weapon to use against US companies, and by extension the labor force that powers them. Though currency debasement and capital controls are available to other countries as a defense, for the US, neither of these tools is available due to the fact that the dollar is the world reserve currency. As such, tariffs are a reasonable defense against the fiat subsidization of foreign governments.

2025-05-13 16:47:48(Textículo em prosa erudita sobre a Ideologia Anarco-Capitalista-Cristã)
https://davipinheiro.com/01-escravos-da-cara-inchada/
A cultura #Woke apropriou-se da imagem sobre a #escravidão. Quando uma pessoa aculturada imagina um #escravo, vem em sua mente a imagem de um ser humano negro, magro e flagelado. Para quem enxerga além das cortinas da mentira, vem em sua mente a imagem de um ser humano de qualquer etnia, gordo e doente.
Democracia, péssimo regime de governo assim classificado pelo seu próprio idealizador: Platão em A República, é o grito da hienas de dentes arreganhados para ampliação do regime escravocrata fomentado pelos #GlobalistasSatanistas.
Um escravo da cara inchada é todo aquele ser humano ignorante inconsciente que alimenta esse sistema em troca de intoxicantes como flúor¹, cloro, glutamato monosódico, gordura trans, corantes, conservantes, refrigerantes, bebidas alcoólicas, psicotrópicos e remédios sintomáticos, tudo embrulhado com mentiras reiteradas.
Como consequência, após os 18 anos de idade o corpo do #EscravoDaCaraInchada sucumbe à tamanha intoxicação e passa a inchar, sendo fisicamente perceptível sua condição de escravo da cara inchada tanto à olho nú quando por reconhecimento facial de qualquer pseudo inteligência artificial.
O círculo vicioso da #EscravidaoDemocratica é tão simples e tosco como o “pão e circo romano”, Mesmo assim é muito difícil para o escravo da cara inchada perceber a própria condição tamanha é sua intoxicação física e mental.
Se um Anarco-Capitalista-Cristão (#Ancapcristão) chega para um escravo da cara inchada e explica sobre esses intoxicantes como instrumento de escravização, dificilmente o escravo da cara inchada irá acreditar pois diferentemente do antigo e aposentado chicote, o novo instrumento da escravidão não dói de imediato e os próprios efeitos da intoxicação impedem-no de raciocinar com clareza.
Portanto, para que os #GlobalistasSatanistas obtivessem sucesso na democratização da escravidão, tiveram que criar um chicote químico e uma ideologia favorável. Quanto às etapas utilizadas para formação dessa ideologia no inconsciente coletivo passo a elencar as 6 grandes mentiras em ordem cronológica:
(1ª etapa) Iluminismo: distanciamento de #Deus e seus ensinamentos, criação de sociedades secretas, exacerbação do ser humano perante o criador na tentativa de projetar o ser humano como seu próprio deus, tornando-o responsável sobre os rumos naturais do planeta. Assim formou-se a base ideológica para o materialismo, ambientalismo, feminismo, controle populacional e ideologia de gêneros;
(2ª etapa) Materialismo: perda do propósito espiritual e do sentido da vida², o que passa a importar são apenas as coisas materiais, acima inclusive do próprio ser humano. A perpetuação da espécie também fica em segundo plano. Assim formou-se a base ideológica para o ambientalismo, feminismo, controle populacional e ideologia de gêneros;
(3ª etapa) Ambientalismo: redução do ser humano à mero câncer do planeta superlotado, atribuído-lhe a responsabilidade por qualquer desastre natural. Assim formou-se a base ideológica para o controle populacional e ideologia de gêneros;
(4ª etapa) Feminismo: enfraquecimento do ser humano por meio da sua divisão em duas categorias: macho e fêmea, os quais são inimigos e não cooperadores. A ideia de igualdade de gêneros é tão antagônica que beira ao conflito cognitivo³: Eles querem separar para dizer que são iguais... Ora, como não pode haver diferenças entre os gêneros se eles são fisicamente e mentalmente diferentes? Nesse diapasão, mesmo não sendo os estados nacionais os arquitetos da escravidão democrática e sim meros fantoches dos globalistas satanistas, o voto feminino foi fundamental para aprovação de leis misândricas com o fito de acelerar a destruição da base familiar do escravo da cara inchada. Importante mencionar que a base familiar dos globalistas satanistas continua sendo patriarcal. Assim formou-se a base ideológica para o controle populacional e ideologia de gêneros;
(5ª etapa) Controle Populacional: “Crescei e multiplicai-vos” é o caralho, Deus não sabe de nada (Iluminismo), o que importa é o dinheiro e filho é caro (Materialismo), para que colocar mais um ser humano nesse planeta doente e superlotado (Ambientalismo), além disso o sexo oposto é meu inimigo (Feminismo). Essa é base ideológica que antecede a ideologia de Controle Populacional, ainda reforçada pela apologia à castração, já que em todas as mídias produzidas com patrocínio oculto de capital globalista satanista tentam normalizar a castração do homem (perda da capacidade de reprodução) desde em desenhos infantis até grandes produções cinematográficas, ora em tom de humor ora em tom de tortura. Assim os escravos da cara inchada do sexo masculino perderam sua identidade, essência e desejo de ser o que são, formando-se a base ideológica para o homossexualismo, ou seja, para a ideologia de gêneros.
(6ª etapa) Ideologia de Gêneros: É a cereja do bolo para os planos do Diabo (Anjo invejoso de Deus que quer destruir a maior criação: nós). Enquanto os globalistas satanistas, dentro de sua sábia ignorância, acreditam estarem chefiando a democratização da escravidão, na verdade também não passam de meros fantoches do Anjo Caído. Com a sexta e última etapa de mentiras para extinção da humanidade (#apocalipse) posta em prática através da Ideologia de Gêneros, fecha-se o ciclo vicioso de mentiras que se auto justificam: Se #Deus não presta, o que vale são os bens materiais, o ser humano é um câncer no planeta, o sexo oposto é inimigo e ter filhos é uma péssima ideia e ser homem másculo é crime, então ser #homossexual é a melhor opção, inclusive vamos castrar os meninos antes da puberdade sem o consentimento dos pais ou mães solo. Aqui também há uma grande bifurcação do círculo vicioso de mentiras, qual seja o gritante conflito cognitivo³: Se todos os homens deixarem de ser másculos, quem vai comer os #gays afeminados? Ou se todas as mulheres deixarem de ser femininas, quem as #sapatonas irão comer? E o pior, se todos passem a ser homossexuais quem vai perpetuar a espécie? Seremos extintos no lapso temporal de apenas uma geração, pois a fraudulenta medicina moderna jamais terá a capacidade de gerar bebês de chocadeira à tempo.
É interessante enxergar que mesmo os Globalistas Satanistas, dentro de sua sábia ignorância, acreditando estarem democratizando a escravidão em benefício próprio, na verdade apenas estão fomentando o apocalipse, ou seja sua própria extinção. Também não terão qualquer lugar especial no inferno, sinônimo de mal é mentira. Portanto os #GlobalistaSatanistas são meros fantoches do #Diabo enganador, tão submissos quanto o Escravo da Cara Inchada…
Interessante também enxergar que o livre arbítrio é uma condição obrigatória para independência da criação (anjo e ser humano). Todos somos livres para escolher entre o bem e o mal, se iremos ser escravos de #Deus ou escravos do Diabo. Se assim não fosse, inexistiria criação pois seríamos mera extensão da consciência do #Criador, em outras palavras: para que exista uma criação, essa deve ter a capacidade de decisão de forma independente, o chamado livre arbítrio.
Com base nisso, temos que não cabe à nos fazer qualquer revolução, tudo está normal, a luta entre o bem e o mal sempre irá existir pois um não existe sem o outro. Nos cabe apenas escolher o lado. Nesse contexto, tenho a seguinte mensagem destinada à você para encerrar o presente Textículo Anarco-Capitalista-Cristão:
------ > Se você for um ANARCO-CAPITALISTA-CRISTÃO passe esta palavra à diante para que a verdade atinja o maior número de ignorantes inconscientes possível;
------ > Se você for um GLOBALISTA SATANISTA, vai viver sua vida, desfrutar da própria fortuna e pare de ser fantoche o Diabo, mentiram para você: não terá qualquer lugar especial quando morrer;
------ > Se você for um ESCRAVO DA CARA INCHADA e não entendeu o que eu disse, por favor me pergunte ou debata comigo, terei o prazer em lhe ajudar a enxergar a verdade. Pare de trabalhar por dinheiro fiduciário, passe a aceitar #Monero e #Bitcoin em troca do seu trabalho, pois isso é o único jeito de sermos financeiramente livres, se tiver alguma dúvida sobre #criptomoedas me pergunte e terei o prazer e ensinar. Se ainda assim você se recusa a enxergar a verdade exposta aqui, por favor aceite #Monero e #Bitcoin quando for dar o seu cú. Ou melhor, cometa suicídio, já que você é um câncer no planeta, salve a natureza.

2025-05-13 06:32:15You don’t have to be a type designer to appreciate what goes into the design of a letterform. In fact, even if you’re just a humble graphic designer, you should have a basic knowledge of what constructs the type you employ.
Typography, for all its concepts, expectations, implications, connotations and artistry, is, ultimately, a system. Just like a body has bones and muscles, every letterform has parts that give it shape, rhythm, and character.
If you're a creative working with type, learning the names of these parts helps you communicate clearly, better analyze your work and others, and design with precision. Everything comes down to a foundational understanding of the anatomy of the letterform and its essential component. So let’s help you with that.
Pangram Pangram Foundry is where the art of typography meets unparalleled craftsmanship. Established in 2018 by designer Mat Desjardins, Pangram Pangram has swiftly risen to become a globally recognized independent type foundry, admired and trusted by industry peers and the design community alike.

2025-05-13 06:21:36Steve Jobs sent me an email saying “Great idea, thank you."
Wait, what? What was the great idea?
new guy at NeXT In October of 1991, I was a new Systems Engineer at NeXT. NeXT, of course, was the company Steve Jobs had founded after leaving Apple in 1985, and which eventually merged back into Apple in 1996. I was one of three employees in Canada, and I think NeXT had about 400 people total.
NeXTMail Mail on the NeXT Computer was pretty amazing in 1991. Multimedia! Fonts! Attachments! Sounds! It’s hard to overstate how cool that was compared to the command line email everybody was used to. Every NeXT user got this email from Steve when they started up their computer.
That message included an attachment of what NeXT called Lip Service, the crazy idea that you could embed an audio file inside an email message. Crazy.
i have an idea
NeXT automatically set everybody up with a first-initial last-name address in the usual way, so I was shayman@next.com, and the big guy was sjobs@next.com.
A few colleagues had somehow acquired cooler email aliases - single letter things, or their first name, or a nickname or an easier to spell version, or whatever. Turns out NeXT had set up some sort of form where you could request an email alias that would redirect to whatever your real email address was.
I also noticed that even though there were seven or eight people at NeXT named Steve, nobody was using the email alias steve@next.com.
So late one Friday night, two weeks into the job, I figured, naively, what the heck, nobody else seems to want it, so I filled in the form asking for steve@next.com to be forwarded to me, shayman@next.com.
In the back of my mind was a vague idea that maybe somebody would have to approve this. But no, it all got set up automatically, and …

2025-02-25 15:20:39If you don't know where your posts are, you might as well just stay in the centralized Twitter. You either take control of your relay lists, or they will control you. Amethyst offers several lists of relays for our users. We are going to go one by one to help clarify what they are and which options are best for each one.
Public Home/Outbox Relays
Home relays store all YOUR content: all your posts, likes, replies, lists, etc. It's your home. Amethyst will send your posts here first. Your followers will use these relays to get new posts from you. So, if you don't have anything there, they will not receive your updates.
Home relays must allow queries from anyone, ideally without the need to authenticate. They can limit writes to paid users without affecting anyone's experience.
This list should have a maximum of 3 relays. More than that will only make your followers waste their mobile data getting your posts. Keep it simple. Out of the 3 relays, I recommend: - 1 large public, international relay: nos.lol, nostr.mom, relay.damus.io, etc. - 1 personal relay to store a copy of all your content in a place no one can delete. Go to relay.tools and never be censored again. - 1 really fast relay located in your country: paid options like http://nostr.wine are great
Do not include relays that block users from seeing posts in this list. If you do, no one will see your posts.
Public Inbox Relays
This relay type receives all replies, comments, likes, and zaps to your posts. If you are not getting notifications or you don't see replies from your friends, it is likely because you don't have the right setup here. If you are getting too much spam in your replies, it's probably because your inbox relays are not protecting you enough. Paid relays can filter inbox spam out.
Inbox relays must allow anyone to write into them. It's the opposite of the outbox relay. They can limit who can download the posts to their paid subscribers without affecting anyone's experience.
This list should have a maximum of 3 relays as well. Again, keep it small. More than that will just make you spend more of your data plan downloading the same notifications from all these different servers. Out of the 3 relays, I recommend: - 1 large public, international relay: nos.lol, nostr.mom, relay.damus.io, etc. - 1 personal relay to store a copy of your notifications, invites, cashu tokens and zaps. - 1 really fast relay located in your country: go to nostr.watch and find relays in your country
Terrible options include: - nostr.wine should not be here. - filter.nostr.wine should not be here. - inbox.nostr.wine should not be here.
DM Inbox Relays
These are the relays used to receive DMs and private content. Others will use these relays to send DMs to you. If you don't have it setup, you will miss DMs. DM Inbox relays should accept any message from anyone, but only allow you to download them.
Generally speaking, you only need 3 for reliability. One of them should be a personal relay to make sure you have a copy of all your messages. The others can be open if you want push notifications or closed if you want full privacy.
Good options are: - inbox.nostr.wine and auth.nostr1.com: anyone can send messages and only you can download. Not even our push notification server has access to them to notify you. - a personal relay to make sure no one can censor you. Advanced settings on personal relays can also store your DMs privately. Talk to your relay operator for more details. - a public relay if you want DM notifications from our servers.
Make sure to add at least one public relay if you want to see DM notifications.
Private Home Relays
Private Relays are for things no one should see, like your drafts, lists, app settings, bookmarks etc. Ideally, these relays are either local or require authentication before posting AND downloading each user\'s content. There are no dedicated relays for this category yet, so I would use a local relay like Citrine on Android and a personal relay on relay.tools.
Keep in mind that if you choose a local relay only, a client on the desktop might not be able to see the drafts from clients on mobile and vice versa.
Search relays:
This is the list of relays to use on Amethyst's search and user tagging with @. Tagging and searching will not work if there is nothing here.. This option requires NIP-50 compliance from each relay. Hit the Default button to use all available options on existence today: - nostr.wine - relay.nostr.band - relay.noswhere.com
Local Relays:
This is your local storage. Everything will load faster if it comes from this relay. You should install Citrine on Android and write ws://localhost:4869 in this option.
General Relays:
This section contains the default relays used to download content from your follows. Notice how you can activate and deactivate the Home, Messages (old-style DMs), Chat (public chats), and Global options in each.
Keep 5-6 large relays on this list and activate them for as many categories (Home, Messages (old-style DMs), Chat, and Global) as possible.
Amethyst will provide additional recommendations to this list from your follows with information on which of your follows might need the additional relay in your list. Add them if you feel like you are missing their posts or if it is just taking too long to load them.
My setup
Here's what I use: 1. Go to relay.tools and create a relay for yourself. 2. Go to nostr.wine and pay for their subscription. 3. Go to inbox.nostr.wine and pay for their subscription. 4. Go to nostr.watch and find a good relay in your country. 5. Download Citrine to your phone.
Then, on your relay lists, put:
Public Home/Outbox Relays: - nostr.wine - nos.lol or an in-country relay. -
.nostr1.com Public Inbox Relays - nos.lol or an in-country relay -
.nostr1.com DM Inbox Relays - inbox.nostr.wine -
.nostr1.com Private Home Relays - ws://localhost:4869 (Citrine) -
.nostr1.com (if you want) Search Relays - nostr.wine - relay.nostr.band - relay.noswhere.com
Local Relays - ws://localhost:4869 (Citrine)
General Relays - nos.lol - relay.damus.io - relay.primal.net - nostr.mom
And a few of the recommended relays from Amethyst.
Final Considerations
Remember, relays can see what your Nostr client is requesting and downloading at all times. They can track what you see and see what you like. They can sell that information to the highest bidder, they can delete your content or content that a sponsor asked them to delete (like a negative review for instance) and they can censor you in any way they see fit. Before using any random free relay out there, make sure you trust its operator and you know its terms of service and privacy policies.

2025-05-24 10:00:40Global fintech leader Revolut has announced a landmark partnership with Lightspark, a pioneer in blockchain infrastructure solutions, to integrate bitcoin’s Lightning Network into its platform.
This collaboration, now live for Revolut users in the UK and select European Economic Area (EEA) countries, marks a transformative leap toward frictionless, real-time transactions—eliminating delays and exorbitant fees traditionally associated with digital asset transfers.
Major update: @RevolutApp is now partnering with @lightspark pic.twitter.com/OUblgrj6Xr
— Lightspark (@lightspark) May 7, 2025
Breaking Barriers in Digital Currency Usability
By adopting Lightspark’s cutting-edge technology, Revolut empowers its 40+ million customers to execute bitcoin transactions instantly at a fraction of current costs.
This integration addresses longstanding pain points in digital currency adoption, positioning bitcoin as a practical tool for everyday payments. Users can now seamlessly send, receive, and store bitcoin with the same ease as traditional fiat currencies, backed by Revolut’s secure platform.
The partnership also advances Revolut’s integration into the open Money Grid, a decentralized network enabling universal interoperability between financial platforms.
This move aligns Revolut with forward-thinking fintechs adopting next-gen solutions like Lightning transactions and Universal Money Addresses (UMA), which simplify cross-border payments by replacing complex wallet codes with human-readable addresses (e.g., $john.smith).
Why This Matters
The collaboration challenges conventional payment rails, which often incur delays of days and high fees for cross-border transfers. By contrast, Lightning Network transactions settle in seconds for minimal cost, revolutionizing peer-to-peer payments, remittances, and merchant settlements. For Revolut users, this means:
- Instant transactions: Send bitcoin globally in under three seconds.
- Near-zero fees: Dramatically reduce costs compared to traditional crypto transfers.
- Enhanced utility: Use bitcoin for daily spending, not just as a speculative asset.
The Road Ahead
Revolut plans to expand Lightning Network access to additional markets in 2025, with ambitions to integrate UMA support for seamless fiat and digital currency interactions. Lightspark will continue optimizing its infrastructure to support Revolut’s scaling efforts, further bridging the gap between blockchain innovation and mainstream finance.
About Revolut
Revolut is a global financial app serving over 40 million customers worldwide. Offering services ranging from currency exchange and stock trading to digital assets and insurance, Revolut is committed to building a borderless financial ecosystem.About Lightspark
Founded by former PayPal and Meta executives, Lightspark develops enterprise-grade solutions for the Lightning Network. Its technology stack empowers institutions to harness bitcoin’s speed and efficiency while maintaining regulatory compliance. -

2025-05-24 10:00:39In the heart of East Africa, where M-Pesa reigns supreme and innovation pulses through bustling markets, a quiet revolution is brewing—one that could redefine how millions interact with money.
Enter Bitika, the Kenyan startup turning bitcoin’s complexity into a three-step dance, merging the lightning speed of sats with the trusted rhythm of mobile money.
At the helm is a founder whose “aha” moment came not in a boardroom, but at his kitchen table, watching his father grapple with the gap between understanding bitcoin and actually using it.
Bitika was born from that friction—a bridge between M-Pesa’s ubiquity and bitcoin’s borderless promise, wrapped in a name as playful as the Swahili slang that inspired it.
But this isn’t just a story about simplifying transactions. It’s about liquidity battles, regulatory tightropes, and a vision to turn Bitika into the invisible rails powering Africa’s Bitcoin future.
Building on Bitcoin
- Tell us a bit about yourself and how you got into bitcoin/fintech, and what keeps you passionate about this space?
I first came across bitcoin in 2020, but like many at that time, I didn’t fully grasp what it really was. It sounded too complicated, probably with the heavy terminologies. Over time, I kept digging deeper and became more curious.
I started digging into finance and how money works and realised this was what I needed to understand bitcoin’s objectives. I realized that bitcoin wasn’t just a new type of money—it was a breakthrough in how we think about freedom, ownership, and global finance.
What keeps me passionate is how bitcoin can empower people—especially in Africa—to take control of their wealth, without relying on unstable systems or middlemen.
- What pivotal moment or experience inspired you to create Bitika? Was there a specific gap in Kenya’s financial ecosystem that sparked the idea?
Yes, this idea was actually born right in my own home. I’ve always been an advocate for bitcoin, sharing it with friends, family, and even strangers. My dad and I had countless conversations about it. Eventually, he understood the concept. But when he asked, “How do I even buy bitcoin?” or “Can you just buy it for me?” and after taking him through binance—that hit me.
If someone I’d educated still found the buying process difficult, how many others were feeling the same way? That was the lightbulb moment. I saw a clear gap: the process of buying bitcoin was too technical for the average Kenyan. That’s the problem Bitika set out to solve.
- How did you identify the synergy between bitcoin and M-Pesa as a solution for accessibility?
M-Pesa is at the center of daily life in Kenya. Everyone uses it—from buying groceries to paying rent. Instead of forcing people to learn new tools, I decided to meet them where they already are. That synergy between M-Pesa and bitcoin felt natural. It’s about bridging what people already trust with something powerful and new.
- Share the story behind the name “Bitika” – does it hold a cultural or symbolic meaning?
Funny enough, Bitika isn’t a deeply planned name. It came while I was thinking about bitcoin and the type of transformation it brings to individuals. In Swahili, we often add “-ka” to words for flair—like “bambika” from “bamba.”
So, I just coined Bitika as a playful and catchy way to reflect something bitcoin-related, but also uniquely local. I stuck with it because thinking of an ideal brand name is the toughest challenge for me.
- Walk us through the user journey – how does buying bitcoin via M-Pesa in “3 simple steps” work under the hood?
It’s beautifully simple.
1. The user enters the amount they want to spend in KES—starting from as little as 50 KES (about $0.30).
2. They input their Lightning wallet address.
3. They enter their M-Pesa number, which triggers an STK push (payment prompt) on their phone. Once confirmed—pap!—they receive bitcoin almost instantly.
Under the hood, we fetch the live BTC price, validate wallet addresses, check available liquidity, process the mobile payment, and send sats via the Lightning Network—all streamlined into a smooth experience for the user.
- Who’s Bitika’s primary audience? Are you focusing on unbanked populations, tech enthusiasts, or both?
Both. Bitika is designed for everyday people—especially the unbanked and underbanked who are excluded from traditional finance. But we also attract bitcoiners who just want a faster, easier way to buy sats. What unites them is the desire for a seamless and low-barrier bitcoin experience.
Community and Overcoming Challenges
- What challenges has Bitika faced navigating Kenya’s bitcoin regulations, and how do you build trust with regulators?
Regulation is still evolving here. Parliament has drafted bills, but none have been passed into law yet. We’re currently in a revision phase where policymakers are trying to strike a balance between encouraging innovation and protecting the public.
We focus on transparency and open dialogue—we believe that building trust with regulators starts with showing how bitcoin can serve the public good.
- What was the toughest obstacle in building Bitika, and how did you overcome it?
Liquidity. Since we don’t have deep capital reserves, we often run into situations where we have to pause operations often to manually restock our bitcoin supply. It’s frustrating—for us and for users. We’re working on automating this process and securing funding to maintain consistent liquidity so users can access bitcoin at any time, without disruption.
This remains our most critical issue—and the primary reason we’re seeking support.
- Are you eyeing new African markets? What’s next for Bitika’s product?
Absolutely. The long-term vision is to expand Bitika into other African countries facing similar financial challenges. But first, we want to turn Bitika into a developer-first tool—infrastructure that others can build on. Imagine local apps, savings products, or financial tools built using Bitika’s simple bitcoin rails. That’s where we’re heading.
- What would you tell other African entrepreneurs aiming to disrupt traditional finance?
Disrupting finance sounds exciting—but the reality is messy. People fear what they don’t understand. That’s why simplicity is everything. Build tools that hide the complexity, and focus on making the user’s life easier. Most importantly, stay rooted in local context—solve problems people actually face.
What’s Next?
- What’s your message to Kenyans hesitant to try bitcoin, and to enthusiasts watching Bitika?
To my fellow Kenyans: bitcoin isn’t just an investment—it’s a sovereign tool. It’s money you truly own. Start small, learn, and ask questions.
To the bitcoin community: Bitika is proof that bitcoin is working in Africa. Let’s keep pushing. Let’s build tools that matter.
- How can the bitcoin community, both locally and globally, support Bitika’s mission?
We’re currently fundraising on Geyser. Support—whether it’s financial, technical, or simply sharing our story—goes a long way. Every sat you contribute helps us stay live, grow our liquidity, and continue building a tool that brings bitcoin closer to the everyday person in Africa.

2025-05-24 10:00:37Custodial Lightning wallets allow users to transact without managing private keys or channel liquidity. The provider handles technical complexities, but this convenience comes with critical trade-offs:
- You don’t control your keys: The custodian holds your bitcoin.
- Centralized points of failure: Servers can be hacked or shut down.
- Surveillance risks: Providers track transaction metadata.
Key Risks of Custodial Lightning Wallets
*1. Hacks and Exit Scams*
Custodians centralize large amounts of bitcoin, attracting hackers:
- Nearly $2.2 billion worth of funds were stolen from hacks in 2024.
- Lightning custodians suffered breaches, losing user funds.
Unlike non-custodial wallets, victims have no recourse since they don’t hold keys.
*2. Censorship and Account Freezes*
Custodians comply with regulators, risking fund seizures:
- Strike (a custodial Lightning app) froze accounts of users in sanctioned regions.
- A U.K. court in 2020 ordered Bitfinex to freeze bitcoin worth $860,000 after the exchange and blockchain sleuthing firm Chainalysis traced the funds to a ransomware payment.
*3. Privacy Erosion*
Custodians log user activity, exposing sensitive data:
- Transaction amounts, receiver addresses, and IPs are recorded.
*4. Service Downtime*
Centralized infrastructure risks outages.
*5. Inflation of Lightning Network Centralization*
Custodians dominate liquidity, weakening network resilience:
- At the moment, 10% of the nodes on Lightning control 80% of the liquidity.
- This centralization contradicts bitcoin’s decentralized ethos.
How to Switch to Self-Custodial Lightning Wallets
Migrating from custodial services is straightforward:
*1. Choose a Non-Custodial Wallet*
Opt for wallets that let you control keys and channels:
- Flash: The self-custodial tool that lets you own your keys, control your coins, and transact instantly.
- Breez Wallet : Non-custodial, POS integrations.
- Core Lightning : Advanced, for self-hosted node operators.
*2. Transfer Funds Securely*
- Withdraw funds from your custodial wallet to a bitcoin on-chain address.
- Send bitcoin to your non-custodial Lightning wallet.
*3. Set Up Channel Backups*
Use tools like Static Channel Backups (SCB) to recover channels if needed.
*4. Best Practices*
- Enable Tor: Mask your IP (e.g., Breez’s built-in Tor support).
- Verify Receiving Addresses: Avoid phishing scams.
- Regularly Rebalance Channels: Use tools like Lightning Pool for liquidity.
Why Self-Custodial Lightning Matters
- Self-custody: Control your keys and funds.
- Censorship resistance: No third party can block transactions.
- Network health: Decentralized liquidity strengthens Lightning.
Self-custodial wallets now rival custodial ease.
Custodial Lightning wallets sacrifice security for convenience, putting users at risk of hacks, surveillance, and frozen funds. As bitcoin adoption grows, so does the urgency to embrace self-custodial solutions.
Take action today:
- Withdraw custodial funds to a hardware wallet.
- Migrate to a self-custodial Lightning wallet.
- Educate others on the risks of custodial control.
The Lightning Network’s potential hinges on decentralization—don’t let custodians become its Achilles’ heel.

2025-05-11 06:23:03Past week summary
From a Self Custody for Organizations perspective, after analyzing the existing protocols (Cerberus, 10xSecurityBTCguide and Glacier) and reading a bunch of relates articles and guides, have wrapped to the conclusion that this format it is good to have as reference. However, something else is needed. For example, a summary or a map of the whole process to provide an overview, plus a way to deliver all the information and the multy-process in a more enjoyable way. Not a job for this hackathon, but with the right collaborations I assume it's possible to: - build something that might introduce a bit more quests and gamification - provide a learning environment (with testnet funds) could also be crucial on educating those unfamiliar with bitcoin onchain dynamics.
Have been learning more and playing around practicing best accessibility practices and how it could be applied to a desktop software like Bitcoin Safe. Thanks to @johnjherzog for providing a screen recording of his first experience and @jasonb for suggesting the tools to be used. (in this case tested/testing on Windows with the Accessibility Insights app). Some insight shared have been also applied to the website, running a full accessibility check (under WCAG 2.2 ADA, and Section 508 standards) with 4 different plugins and two online tools. I recognize that not all of them works and analyze the same parameters, indeed they complement each other providing a more accurate review.
For Bitcoin Safe interface improvements, many suggestions have been shared with @andreasgriffin , including: - a new iconset, including a micro-set to display the number of confirmed blocs for each transaction - a redesigned History/Dashboard - small refinements like adding missing columns on the tables - allow the user to select which columns to be displayed - sorting of unconfirmed transactions - Defining a new style for design elements like mempool blocks and quick receive boxes You can find below some screenshots with my proposals that hopefully will be included in the next release.
Last achievement this week was to prepare the website https://Safe.BTC.pub, the container where all the outcomes f this experiment will be published. You can have a look, just consider it still WIP. Branding for the project has also been finalized and available in this penpot file https://design.penpot.app/#/workspace?team-id=cec80257-5021-8137-8005-eab60c043dd6&project-id=cec80257-5021-8137-8005-eab60c043dd8&file-id=95aea877-d515-80ac-8006-23a251886db3&page-id=132f519a-39f4-80db-8006-2a41c364a545
What's for next week
After spending most of the time learning and reading material, this coming week will be focused on deliverables. The goal as planned will be to provide: - Finalized Safe₿its brand and improve overall desktop app experience, including categorization of transactions and addresses - An accessibility report or guide for Bitcoin Safe and support to implement best practices - A first draft of the Self-Custody for Organizations guide/framework/protocol, ideally delivered through the website http://Safe.BTC.pub in written format, but also as FlowChart to help have an overview of the whole resources needed and the process itself. This will clearly define preparations and tools/hardwares needed to successfully complete the process.

2025-02-21 18:15:52"Malcolm Forbes recounts that a lady, wearing a faded cotton dress, and her husband, dressed in an old handmade suit, stepped off a train in Boston, USA, and timidly made their way to the office of the president of Harvard University. They had come from Palo Alto, California, and had not scheduled an appointment. The secretary, at a glance, thought that those two, looking like country bumpkins, had no business at Harvard.
— We want to speak with the president — the man said in a low voice.
— He will be busy all day — the secretary replied curtly.
— We will wait.
The secretary ignored them for hours, hoping the couple would finally give up and leave. But they stayed there, and the secretary, somewhat frustrated, decided to bother the president, although she hated doing that.
— If you speak with them for just a few minutes, maybe they will decide to go away — she said.
The president sighed in irritation but agreed. Someone of his importance did not have time to meet people like that, but he hated faded dresses and tattered suits in his office. With a stern face, he went to the couple.
— We had a son who studied at Harvard for a year — the woman said. — He loved Harvard and was very happy here, but a year ago he died in an accident, and we would like to erect a monument in his honor somewhere on campus.— My lady — said the president rudely —, we cannot erect a statue for every person who studied at Harvard and died; if we did, this place would look like a cemetery.
— Oh, no — the lady quickly replied. — We do not want to erect a statue. We would like to donate a building to Harvard.
The president looked at the woman's faded dress and her husband's old suit and exclaimed:
— A building! Do you have even the faintest idea of how much a building costs? We have more than seven and a half million dollars' worth of buildings here at Harvard.
The lady was silent for a moment, then said to her husband:
— If that’s all it costs to found a university, why don’t we have our own?
The husband agreed.
The couple, Leland Stanford, stood up and left, leaving the president confused. Traveling back to Palo Alto, California, they established there Stanford University, the second-largest in the world, in honor of their son, a former Harvard student."

2025-02-09 16:50:04There has been a good bit of discussion on Nostr over the past few days about the merits of zaps as a method of engaging with notes, so after writing a rather lengthy article on the pros of a strategic Bitcoin reserve, I wanted to take some time to chime in on the much more fun topic of digital engagement.
Let's begin by defining a couple of things:
Nostr is a decentralized, censorship-resistance protocol whose current biggest use case is social media (think Twitter/X). Instead of relying on company servers, it relies on relays that anyone can spin up and own their own content. Its use cases are much bigger, though, and this article is hosted on my own relay, using my own Nostr relay as an example.
Zap is a tip or donation denominated in sats (small units of Bitcoin) sent from one user to another. This is generally done directly over the Lightning Network but is increasingly using Cashu tokens. For the sake of this discussion, how you transmit/receive zaps will be irrelevant, so don't worry if you don't know what Lightning or Cashu are.
If we look at how users engage with posts and follows/followers on platforms like Twitter, Facebook, etc., it becomes evident that traditional social media thrives on engagement farming. The more outrageous a post, the more likely it will get a reaction. We see a version of this on more visual social platforms like YouTube and TikTok that use carefully crafted thumbnail images to grab the user's attention to click the video. If you'd like to dive deep into the psychology and science behind social media engagement, let me know, and I'd be happy to follow up with another article.
In this user engagement model, a user is given the option to comment or like the original post, or share it among their followers to increase its signal. They receive no value from engaging with the content aside from the dopamine hit of the original experience or having their comment liked back by whatever influencer they provide value to. Ad revenue flows to the content creator. Clout flows to the content creator. Sales revenue from merch and content placement flows to the content creator. We call this a linear economy -- the idea that resources get created, used up, then thrown away. Users create content and farm as much engagement as possible, then the content is forgotten within a few hours as they move on to the next piece of content to be farmed.
What if there were a simple way to give value back to those who engage with your content? By implementing some value-for-value model -- a circular economy. Enter zaps.
Unlike traditional social media platforms, Nostr does not actively use algorithms to determine what content is popular, nor does it push content created for active user engagement to the top of a user's timeline. Yes, there are "trending" and "most zapped" timelines that users can choose to use as their default, but these use relatively straightforward engagement metrics to rank posts for these timelines.
That is not to say that we may not see clients actively seeking to refine timeline algorithms for specific metrics. Still, the beauty of having an open protocol with media that is controlled solely by its users is that users who begin to see their timeline gamed towards specific algorithms can choose to move to another client, and for those who are more tech-savvy, they can opt to run their own relays or create their own clients with personalized algorithms and web of trust scoring systems.
Zaps enable the means to create a new type of social media economy in which creators can earn for creating content and users can earn by actively engaging with it. Like and reposting content is relatively frictionless and costs nothing but a simple button tap. Zaps provide active engagement because they signal to your followers and those of the content creator that this post has genuine value, quite literally in the form of money—sats.
I have seen some comments on Nostr claiming that removing likes and reactions is for wealthy people who can afford to send zaps and that the majority of people in the US and around the world do not have the time or money to zap because they have better things to spend their money like feeding their families and paying their bills. While at face value, these may seem like valid arguments, they, unfortunately, represent the brainwashed, defeatist attitude that our current economic (and, by extension, social media) systems aim to instill in all of us to continue extracting value from our lives.
Imagine now, if those people dedicating their own time (time = money) to mine pity points on social media would instead spend that time with genuine value creation by posting content that is meaningful to cultural discussions. Imagine if, instead of complaining that their posts get no zaps and going on a tirade about how much of a victim they are, they would empower themselves to take control of their content and give value back to the world; where would that leave us? How much value could be created on a nascent platform such as Nostr, and how quickly could it overtake other platforms?
Other users argue about user experience and that additional friction (i.e., zaps) leads to lower engagement, as proven by decades of studies on user interaction. While the added friction may turn some users away, does that necessarily provide less value? I argue quite the opposite. You haven't made a few sats from zaps with your content? Can't afford to send some sats to a wallet for zapping? How about using the most excellent available resource and spending 10 seconds of your time to leave a comment? Likes and reactions are valueless transactions. Social media's real value derives from providing monetary compensation and actively engaging in a conversation with posts you find interesting or thought-provoking. Remember when humans thrived on conversation and discussion for entertainment instead of simply being an onlooker of someone else's life?
If you've made it this far, my only request is this: try only zapping and commenting as a method of engagement for two weeks. Sure, you may end up liking a post here and there, but be more mindful of how you interact with the world and break yourself from blind instinct. You'll thank me later.

2025-05-24 09:57:37Decentralization refers to control/power, and relates to censorship resistance. That is it, it is not more complicated then that. Resilience is a function of redundancy; a centralized censored system can have a redundant set-up and therefor be resilient.
Take Bitcoin; the blockchain is a central database, it is resilient because it has many redundant copies among a lot of different nodes. The message (txs and blocks) propagation is decentralized due to existence of a p2p network among these nodes, making the data distribution censorship resistant (hello op_return debate). But onchain transactions themselves are NOT p2p, they require a middlemen (a miner) because it is a central database, as opposed to something like lightning which is p2p. Peer to Peer says something about relative architectural hierarchical position/relation. P2P provides censorship resistance because it entails equal power relations, provided becoming a peer is permissionless. What makes onchain transactions censorship resistant is that mining is permissionless, and involves this open power struggle/game where competition results in a power distribution among players, meaning (hopefully) decentralization. The fact users rely on these middlemen is mitigated by this decentralization on the one hand, and temper-proofing via cryptographic signatures on the other, resulting in what we call trustlessness (or trust minimization for the autists in the room); we only rely on a miner to perform a job (including your tx into a block), but we don’t trust the miner to perform the job correctly, this we can verify ourselves.
This leads us to Nostr, because that last part is exactly what Nostr does as well. It uses cryptography to get tamper-proof messaging, which then allows you to use middle-men in a trust minimized way. The result is decentralization because in general terms, any middle man is as good as any other (same as with miners), and becoming such a middleman is permissionless(somewhat, mostly); which in turn leads to censorship resistance. It also allows for resilience because you are free to make things as redundant as you'd like.
Ergo, the crux is putting the cryptography central, making it the starting point of the system; decentralization then becomes an option due to trust minimization. The difference between Bitcoin an Nostr, is that Bitcoin maintains a global state/central ledger and needs this PoW/Nakamoto consensus fanfare; Nostr rests itself with local perspectives on 'the network'.
The problem with the Fediverse, is that it does not provide trust minimization in relation to the middlemen. Sure, there are a lot different servers, but you rely on a particular one (and the idea you could switch never really seemed to have materialized in a meaningful way). It also fails in permisionlessness because you rely on the association between servers, i.e. federation, to have meaningful access to the rest of the network. In other words, it is more a requirement of association than freedom of association; you have the freedom to be excommunicated.
The problem with ATproto is that is basically does not solve this dynamic; it only complicates it by pulling apart the components; identity and data, distribution and perspective are now separated, and supposedly you don’t rely on any particular one of these sub-component providers in the stack; but you do rely on all these different sub-component providers in the stack to play nice with each other. And this ‘playing nice’ is just the same old ‘requirement of association’ and ‘freedom of excommunication’ that looms at the horizon.
Yes, splitting up the responsibilities of identity, hosting and indexing is what is required to safe us from the platform hellscape which at this stage takes care of all three. But as it turns out, it was not a matter cutting those up into various (on paper) interchangeable middlemen. All that is required is putting cryptographic keys in the hands of the user; the tamperproofing takes care of the rest, simply by trust minimizing the middlemen we use. All the sudden it does not matter which middlemen we use, and no one is required to play nice; we lost the requirement of association, and gained freedom of association, which was the purpose of censorship resistance and therefor decentralization, to begin with.

Output
And now, we have a demonstration of the final result of this tool, with some quick cleaning up. The video we will be using this tool on is titled Nostr Apps 101 by nostr:npub1nxy4qpqnld6kmpphjykvx2lqwvxmuxluddwjamm4nc29ds3elyzsm5avr7 during Nostrasia. The following thread is an analog to the modular articles we are constructing for Alexandria, and I hope it conveys the functionality we want to create in the knowledge space. Note, this tool is the first step! You could use a different prompt that is most appropriate for the specific context of the transcript you are working with, but you can also manually clean up any discrepancies that don't portray the video accurately. You can now view the article on #Alexandria https://next-alexandria.gitcitadel.eu/publication?d=nostr-apps-101

2025-02-07 14:33:31After many months of ideation, research, and heads-down building, @nostr:npub1wf4pufsucer5va8g9p0rj5dnhvfeh6d8w0g6eayaep5dhps6rsgs43dgh9 and myself are excited to announce our new project called Vertex.
Vertex’s mission is to provide developers and builders with the most up-to-date and easy-to-use social graph tools.
Our services will enable our future customers to improve the experience they provide by offering:
- Protection against impersonation and DoS attacks
- Personalized discovery and recommendations.
All in an open, transparent and interoperable way.
Open and Interoperable
We have structured our services as NIP-90 Data Vending Machines. We are currently using these DVMs and we are eager to hear what the community thinks and if anyone has suggestions for improvements.
Regardless of their specific structures, using DVMs means one very important thing: no vendor lock-in.
Anyone can start processing the same requests and compete with us to offer the most accurate results at the best price. This is very important for us because we are well aware that services like ours can potentially become a central point of failure. The ease with which we can be replaced by a competitor will keep us on our toes and will continue to motivate us to build better and better experiences for our customers, all while operating in an ethical and open manner.
Speaking of openness, we have released all of our code under the MIT license, which means that anyone can review our algorithms, and any company or power user can run their own copies of Vertex if they so wish.
We are confident in this decision because the value of Vertex is not in the software. It is in the team who designed and implemented it – and now continually improves, manages and runs it to provide the most accurate results with the lowest latency and highest uptime.
What we offer
We currently support three DVMs, but we plan to increase our offering substantially this year.
VerifyReputation
: give your users useful and personalized information to asses the reputation of an npub, minimizing the risk of impersonations.RecommendFollows
: give your users personalized recommendations about interesting npubs they might want who to follow.SortAuthors
: give your users the ability to sort replies, comments, zaps, search results or just about anything using authors’ reputations.

2025-05-24 09:35:09„Aaaach, was für ein herrlicher Tag!“
In Berlin geht man hochmotiviert an die Arbeit, in der tiefen Überzeugung stets die richtigen Entscheidungen zu treffen, die Steuern der Einzahler ausschließlich für wohlüberlegte, notwendige Investitionen auszugeben und Entscheidungen zu treffen, die im dem Umfeld, in dem man sich bewegt, als höchst sinnvoll erachtet werden. Zustimmung von allen Seiten, dann muss es ja richtig sein.
Man fährt im Dienstwagen ins Regierungsviertel, sieht die vielen geschäftigen Menschen, wie sie ebenfalls zur Arbeit eilen. Man freut sich darüber, dass alles so gut läuft, dank der überragenden Kompetenz, die man einbringen darf und die das alles ermöglicht.
In Gedanken klopft man sich auf die Schulter und sagt sich im Stillen: „Bist schon ein geiler Typ, der richtig was bewegen kann, bewegen kann.“
Man hat auch schon erkannt, dass die zunehmende Kriminalität, vorzugsweise mit einem unsachgemäß gebrauchten Messer, durch den schlechten Einfluss der sozialen Medien entstanden ist und schon entsprechende Maßnahmen auf den Weg gebracht, um das durch geleitete Meinungsäußerungen, selbstverständlich zum Wohle aller, zu unterbinden. Man ist ja nicht umsonst in diese verantwortungsvolle Position gelangt. „Endlich am Ziel!“
„Messerattacken sind unschön, unschön, aber man muss auch berücksichtigen, dass viele der Attentäter und Attentäterinnen in ihren Herkunftsländern Schlimmes erlebt haben und dadurch traumatisiert wurden. Den betroffenen Traumaopfern kann ja nichts Besseres passieren, als in eine deutsche Psychiatrie zu kommen, wo sie die allerbeste Therapie erfahren, um wieder glückliche Menschen der Gesellschaft zu werden.
** **
Und jeder, der nicht die große soziale Aufgabe erkennt, die wir uns gestellt haben und auch effizient umsetzen, muss es eben noch besser erklärt bekommen, erklärt bekommen. Daran müssen wir noch arbeiten. (Muss ich mir notieren, damit ich meinem Sekretär die Anweisung erteile, das in die Wege zu leiten). Und jeder, der sich dagegen sträubt, zeigt damit eindeutig, dass er zum rechten Rand gehört. Was denen nur einfällt? Da müssen klare Zeichen gesetzt werden, und das muss unter allen Umständen unterbunden werden, unterbunden werden.
** **
Sowas schadet der Demokratie, es delegitimiert sie“.
Zum Schutz der braven Bürger arbeitet man auch fleißig daran, Deutschland, in neuem Selbstbewusstsein, zur stärksten Kraft in Europa zu machen. Mit der Stationierung von deutschen Soldaten an der Ostfront, pardon, an der Ostflanke, zeigt man dem bösen, aggressiven Russen schon mal, was eine Harke ist. „Und das ist ja erst der Anfang, der Anfang. Warte nur ab!“
„Was noch? Ach ja, die Wirtschaft. Solange die nicht auf die Barrikaden geht, das sehe ich derzeit nicht, scheint es ja noch keinen akuten Handlungsbedarf zu geben. Darum kümmern wir uns später. Immerhin halten sich die Wirtschaftsprognosen in einem akzeptablen Rahmen und die Priorität (die kann auch nicht jeder richtig setzen) der Investitionen muss derzeit auf dem wichtigsten Bereich, der Aufrüstung liegen, Aufrüstung liegen. Schließlich werden wir bald angegriffen.
** **
Ich darf nicht vergessen, meinen Sekretär zu beauftragen, meine Bestellung im Feinkostladen abholen zu lassen, sonst gibt’s Zuhause Ärger. Ach ja, und die Anzüge und die Wäsche muss auch noch aus der Reinigung abgeholt werden. Darf ich nicht vergessen, nicht vergessen.
** **
Wie viele Reinigungen gäbe es nicht, wenn wir Politiker nicht wären, nicht wären. Viele sichere Arbeitsplätze, gut so!
** **
Was, schon da? Das ging aber heute schnell. Kein Stau. Ja, der Chauffeur ist schon ein Guter, der weiß, wo man lang muss, um Baustellen zu umfahren. Allerdings muss ich ihm bei nächster Gelegenheit noch einmal deutlich sagen, dass er bitte die Sitzheizung früher anzuschalten hat, anzuschalten hat! Dass der sich das immer noch nicht gemerkt hat, unmöglich!“
Wen wundert es, wenn in dieser Wonnewelt der Selbstüberschätzung von Unsererdemokratie gesprochen wird, so entrückt vom Alltag, in einem Raumschiff, dass völlig losgelöst von der Realität über allem schwebt.
„Ich müsste ja verrückt sein, wenn ich an diesen Zuständen etwas ändern wollte. Warum auch, es läuft doch und mir geht es doch gut. Ich habe ein gutes Einkommen, kann mir allerhand leisten, Haus ist bezahlt, Frau ist gut untergebracht, Kinder sind versorgt, wie die Zeit vergeht. Und wenn ich mal ausscheide, erhalte ich weiter meine Bezüge und muss nicht an mein Vermögen ran, man will ja auch den Kindern was hinterlassen. Schadet ja nicht, wenn ich mich etwas einschränke, und der eine oder andere Job wird schon an mich herangetragen werden, schließlich habe ich ja erstklassige Kontakte, die dem einen oder anderen sicher etwas wert sein werden.
** **
Na, dann woll’n wir mal wieder, woll’n wir mal wieder!“

2025-05-10 09:50:45Information ohne Reflexion ist geistiger Flugsand. \ Ernst Reinhardt
Der lateinische Ausdruck «Quo vadis» als Frage nach einer Entwicklung oder Ausrichtung hat biblische Wurzeln. Er wird aber auch in unserer Alltagssprache verwendet, laut Duden meist als Ausdruck von Besorgnis oder Skepsis im Sinne von: «Wohin wird das führen?»
Der Sinn und Zweck von so mancher politischen Entscheidung erschließt sich heutzutage nicht mehr so leicht, und viele Trends können uns Sorge bereiten. Das sind einerseits sehr konkrete Themen wie die zunehmende Militarisierung und die geschichtsvergessene Kriegstreiberei in Europa, deren Feindbildpflege aktuell beim Gedenken an das Ende des Zweiten Weltkriegs beschämende Formen annimmt.
Auch das hohe Gut der Schweizer Neutralität scheint immer mehr in Gefahr. Die schleichende Bewegung der Eidgenossenschaft in Richtung NATO und damit weg von einer Vermittlerposition erhält auch durch den neuen Verteidigungsminister Anschub. Martin Pfister möchte eine stärkere Einbindung in die europäische Verteidigungsarchitektur, verwechselt bei der Argumentation jedoch Ursache und Wirkung.
Das Thema Gesundheit ist als Zugpferd für Geschäfte und Kontrolle offenbar schon zuverlässig etabliert. Die hauptsächlich privat finanzierte Weltgesundheitsorganisation (WHO) ist dabei durch ein Netzwerk von sogenannten «Collaborating Centres» sogar so weit in nationale Einrichtungen eingedrungen, dass man sich fragen kann, ob diese nicht von Genf aus gesteuert werden.
Das Schweizer Bundesamt für Gesundheit (BAG) übernimmt in dieser Funktion ebenso von der WHO definierte Aufgaben und Pflichten wie das deutsche Robert Koch-Institut (RKI). Gegen die Covid-«Impfung» für Schwangere, die das BAG empfiehlt, obwohl es fehlende wissenschaftliche Belege für deren Schutzwirkung einräumt, formiert sich im Tessin gerade Widerstand.
Unter dem Stichwort «Gesundheitssicherheit» werden uns die Bestrebungen verkauft, essenzielle Dienste mit einer biometrischen digitalen ID zu verknüpfen. Das dient dem Profit mit unseren Daten und führt im Ergebnis zum Verlust unserer demokratischen Freiheiten. Die deutsche elektronische Patientenakte (ePA) ist ein Element mit solchem Potenzial. Die Schweizer Bürger haben gerade ein Referendum gegen das revidierte E-ID-Gesetz erzwungen. In Thailand ist seit Anfang Mai für die Einreise eine «Digital Arrival Card» notwendig, die mit ihrer Gesundheitserklärung einen Impfpass «durch die Hintertür» befürchten lässt.
Der massive Blackout auf der iberischen Halbinsel hat vermehrt Fragen dazu aufgeworfen, wohin uns Klimawandel-Hysterie und «grüne» Energiepolitik führen werden. Meine Kollegin Wiltrud Schwetje ist dem nachgegangen und hat in mehreren Beiträgen darüber berichtet. Wenig überraschend führen interessante Spuren mal wieder zu internationalen Großbanken, Globalisten und zur EU-Kommission.
Zunehmend bedenklich ist aber ganz allgemein auch die manifestierte Spaltung unserer Gesellschaften. Angesichts der tiefen und sorgsam gepflegten Gräben fällt es inzwischen schwer, eine zukunftsfähige Perspektive zu erkennen. Umso begrüßenswerter sind Initiativen wie die Kölner Veranstaltungsreihe «Neue Visionen für die Zukunft». Diese möchte die Diskussionskultur reanimieren und dazu beitragen, dass Menschen wieder ohne Angst und ergebnisoffen über kontroverse Themen der Zeit sprechen.
Quo vadis – Wohin gehen wir also? Die Suche nach Orientierung in diesem vermeintlichen Chaos führt auch zur Reflexion über den eigenen Lebensweg. Das ist positiv insofern, als wir daraus Kraft schöpfen können. Ob derweil der neue Papst, dessen «Vorgänger» Petrus unsere Ausgangsfrage durch die christliche Legende zugeschrieben wird, dabei eine Rolle spielt, muss jede/r selbst wissen. Mir persönlich ist allein schon ein Führungsanspruch wie der des Petrusprimats der römisch-katholischen Kirche eher suspekt.

2025-05-24 08:19:41Music in media is like audio umami, the perfect seasoning in a recipe. It has the ability to enhance flavor and provide depth. Daniel Siegel Alonso examines how music is indispensable in enchanting consumers, from the memorable jingles of television commercials to the emotionally charged earworms in viral videos. Its influence is ubiquitous, transforming ordinary content into unforgettable experiences, evoking emotions, and molding cultural trends.
Television Commercials: The Jingle Jungle
Siegel Alonso begins by considering the television commercial. Music is the secret weapon in advertising and marketing, where attention spans can be shorter than the length of a cat video on TikTok. With its catchy melody and simple lyrics, the classic jingle is a masterclass in auditory branding. Do you remember 1971's "I'd Like to Buy the World a Coke"? That was more than just a tune; it was a cultural touchstone.
Today, in modern advertising, music's role transcends nostalgic jingles. Brands now curate full-fledged soundtracks to build an emotional narrative. Take Apple's commercials, for example. They often spotlight indie artists whose songs capture the essence of innovation and simplicity. These choices aren't random; they align with the brand's identity and leave a lasting impression.
Music Videos: The Visual Symphony
Music videos are the perfect union of audio and visual storytelling and have revolutionized how people consume music. These clips are not merely promotional tools but are art forms. At its peak, music videos were cultural events. Nobody took advantage of the medium better than Madonna. Think of her "Justify My Love" video—a short film that was so subversive that MTV banned it. (Ever the businesswoman, The Material Girl decided to make the controversial video available commercially as a video single, marking the first time a musician released a single in this format in the United States.)
Daniel Siegel Alonso fast forwards to the current age of social media, with channels like YouTube and TikTok breathing new life into the music video. Artists can now connect directly with their audience, bypassing cautious publicists and conservative record company executives. This democratization has led to a surge in creativity. Think about Childish Gambino's cinematic "This is America." The music video sparked widespread discussion and analysis with its in-your-face imagery and complex themes. It wasn't just a song but a statement.
Social Media: The Viral Soundtrack
Music is the magical ingredient in social media that can instantly catapult content into viral fame. Platforms like TikTok have turned short, catchy music clips into a global phenomenon. A 15-second snippet can lead to myriad dance challenges, lip-sync clips, and memes, propelling relatively obscure singers to stardom overnight.
Daniel Siegel Alonso uses Lil Nas X's "Old Town Road" as a key example. With its genre-blending sound, the song became a sensation largely thanks to TikTok. Users created countless videos featuring the song, and the track's infectious energy spread like wildfire. The result was a record-breaking run on the Billboard Hot 100—and a Grammy win!
Even Instagram's Stories and Reels leverage songs to enrich their user experience. Whether it's a tearjerker ballad emphasizing heartfelt memories or an aggressive track fueling a workout video, music layers in emotional content that words and images can't achieve.
The Emotional Manipulator
Music's influence in media lies in its power to manipulate emotions—the invisible puppeteer tugs at the heartstrings, stirring nostalgia, joy, sadness, or excitement. Filmmakers and content creators understand this well. Imagine watching a horror flick without a creepy soundtrack.
In television shows, music often acts as an additional character on screen. Netflix's "Stranger Things" and HBO's "Game of Thrones" have iconic soundtracks that are instantly recognizable and have even revitalized musicians' careers (think Kate Bush and her iconic song "Running Up That Hill"). These scores aren't just background fodder; they are crucial to storytelling by creating tension and enhancing dramatic moments.
Cultural Shaper
Beyond its emotional impact, music in media also serves as a cultural shaper. It impacts everything from fashion to language and even social movements. Consider MTV's influence and reach at its height in the 1980s and 1990s. The cable channel didn't just air music videos; it created superstars and defined an era, influencing everything from hairdos to political views.
While MTV may not be the behemoth it once was, social media platforms continue the tradition today. Viral music trends can spark global discussions. For instance, the Black Lives Matter movement saw numerous musicians penning powerful anthems that became rallying cries, shared widely on social media. In this context, music transcends entertainment; it's a vehicle for evolution.
Conclusion
In the grand tapestry of media, Daniel Siegel Alonso asserts that music is the thread that weaves everything together. It turns commercials into cultural icons, music videos into visual feasts, and social media content into viral sensations. Its power to elicit emotion, contribute to culture, and tell unique stories makes it an invaluable tool for creators.
If there are stories to tell and products to sell, music will remain at the heart of media, striking the right chords and leaving an unforgettable mark on our collective psyche. Ultimately, it's not just about the notes and melodies; it's about the feelings and memories they arouse, making music the unsung hero in the ever-changing media landscape.

For generations before generative text, writers have used the em dash to hop between thoughts, emotions, and ideas. Dickens shaped his morality tales with it, Woolf’s stream-of-consciousness flowed through it, Kerouac let it drive his jazz-like prose. Today, Sally Rooney threads it through her quiet truths of the heart.
But this beloved punctuation mark has become a casualty of the algorithmic age. The em dash has been so widely adopted by AI-generated text that even when used by human hands, it begs the question: was this actually written or apathetically prompted?
The battle for the soul of writing is in full swing. And the human fightback starts here. With a new punctuation mark that serves as a symbol of real pondering, genuine daydreaming, and true editorial wordsmithery. Inspired by Descartes’ belief that thinking makes us human, the am dash is a small but powerful testament that the words you’ve painstakingly and poetically pulled together are unequivocally, certifiably, and delightfully your own.
Let's reclain writig from AI—oneam dash at time.

2025-05-10 05:11:27Consider the following two charts from A History of Clojure which detail the introduction and retention of new code by release for both Clojure and for Scala.
While this doesn't necessarily translate to library stability, it's reasonable to assume that the attitude of the Clojure maintainers will seep into the community. And that assumption is true.
Consider a typical Javascript program. What is it comprised of? Objects, objects, and more objects. Members of those objects must be either introspected or divined. Worse, it's normal to monkeypatch those objects, so the object members may (or may not) change over time.
Now, consider a typical Clojure program. What is it comprised of? Namespaces. Those namespaces contain functions and data. Functions may be dynamically generated (via macros), but it is extremely rare to "monkeypatch" a namespace. If you want to know what functions are available in a namespace, you can simply read the source file.

2025-01-25 22:16:54President Trump plans to withdraw 20,000 U.S. troops from Europe and expects European allies to contribute financially to the remaining military presence. Reported by ANSA, Trump aims to deliver this message to European leaders since taking office. A European diplomat noted, “the costs cannot be borne solely by American taxpayers.”
The Pentagon hasn't commented yet. Trump has previously sought lower troop levels in Europe and had ordered cuts during his first term. The U.S. currently maintains around 65,000 troops in Europe, with total forces reaching 100,000 since the Ukraine invasion. Trump's new approach may shift military focus to the Pacific amid growing concerns about China.

2025-05-08 05:25:48Safe Bits & Self Custody Tips
The journey of onboarding a user and create a bitcoin multiSig setup begins far before opening a desktop like Bitcoin Safe (BS) or any other similar application. Bitcoin Safe seems designed for families and people that want to start exploring and learning about multiSig setup. The need for such application and use of it could go much further, defining best practices for private organizations that aim to custody bitcoin in a private and anonymous way, following and enjoy the values and standards bitcoin has been built for.
Intro
Organizations and small private groups like families, family offices and solopreneurs operating on a bitcoin standard will have the need to keep track of transactions and categorize them to keep the books in order. A part of our efforts will be spent ensuring accessibility standards are in place for everyone to use Bitcoin Safe with comfort and safety.
We aim with this project to bring together the three Designathon ideas below: - Bitcoin Safe: improve its overall design and usability. - No User Left Behind: improve Bitcoin Safe accessibility. - Self-custody guidelines for organizations: How Bitcoin Safe can be used by private organization following best self-custody practices.
We are already halfway of the first week, and here below the progress made so far.
Designing an icon Set for Bitcoin Safe
One of the noticeable things when using BS is the inconsistency of the icons, not just in colors and shapes, but also the way are used. The desktop app try to have a clean design that incorporate with all OS (Win, macOS, Linux) and for this reason it's hard to define when a system default icon need to be used or if a custom one can be applied instead. The use of QT Ui framework for python apps help to respond to these questions. It also incorporates and brig up dome default settings that aren't easily overwritten.
Here below you can see the current version of BS:
Defining a more strict color palette for Bitcoin Safe was the first thing!
How much the icons affect accessibility? How they can help users to reach the right functionality? I took the challenge and, with PenPot.app, redesigned the icons based on the grid defined in the https://bitcoinicons.com/ and proposing the implementation of it to have a cleaner and more consistent look'n feel, at least for the icons now.
What's next
I personally look forward to seeing these icons implemented soon in Bitcoin Safe interface. In the meantime, we'll focus on delivering an accessibility audit and evaluate options to see how BS could be used by private organizations aiming to become financially sovereign with self-custody or more complex bitcoin multiSig setups.
One of the greatest innovations BS is bringing to us is the ability to sync the multiSig wallets, including PBST, Categories and labels, through the nostr decentralized protocol, making current key custodial services somehow obsolete. Second-coolest feature that this nostr implementation brings is the ability to have a build-in private chat that connect and enable the various signers of a multiSig to communicate and sign transactions remotely. Where have you seen something like this before?
Categories UX and redesign is also considered in this project. We'll try to understand how to better serve this functionality to you, the user, really soon.
Stay tuned!
