Da nema besplatnog ručka sigurno ste čuli svaki put kad bi neko poželio da naglasi da se sve na neki način plaća, iako možda tu cijenu ne primjećujemo odmah. Međutim, kada govorimo o događaju od kojeg je prošlo tačno 15 godina onda o „ručku“ ne govorimo u prenešenom smislu, već o porudžbini pice čija tržišna vrijednost iz godine u godinu dostiže iznos koji je čini najskupljom hranom koja je ikad poručena.
Tog 22. maja 2010. godine čovjek sa Floride pod imenom Laslo Hanjec potrošio je 10.000 bitcoina na dvije velike pice. U to vrijeme, ta količina bitcoina imala je tržišnu vrijednost od oko 41 dolar. Ako uzmemo u obzir da je vrijednost jedne jedinice ove digitalne valute danas nešto više od 111.000 dolara, tih 10.000 bitcoina danas bi značilo vrijednost od 1,11 milijardi dolara.
Nesvakidašnji događaj u digitalnoj i ugostiteljskoj istoriji, nastao zbog znatiželje poručioca koji je želio da se uvjeri da koristeći bitcoin može da plati nešto u stvarnom svijetu, pretvorio se u Bitcoin Pizza Day, kao podsjetnik na trenutak koji je označio prelaz bitcoina iz apstraktnog kriptografskog eksperimenta u nešto što ima stvarnu vrijednost.
Hanjec je bio znatiželjan i pitao se da li se prva, a u to vrijeme i jedina kriptovaluta može iskoristiti za kupovinu nečeg opipljivog. Objavio je ponudu na jednom forumu koja je glasila: 10.000 BTC za dvije pice. Jedan entuzijasta se javio, naručio pice iz restorana Papa John’s i ispisao zanimljivu stranicu istorije digitalne imovine.
Taj inicijalni zabilježeni finansijski dogovor dao je bitcoinu prvu široko prihvaćenu tržišnu vrijednost: 10.000 BTC za 41 dolar, čime je bitcoin napravio svoj prvi korak ka onome što danas mnogi zovu digitalnim zlatom.
Šta je zapravo bitcoin?
Bitcoin je oblik digitalnog novca koji je osmišljen da bude decentralizovan, transparentan i otporan na uticaj centralnih banaka. Kreirao ga je 2009. godine anonimni autor poznat kao Satoši Nakamoto, neposredno nakon globalne finansijske krize 2008. godine. U svojoj suštini, bitcoin je protokol, skup pravila koja sprovodi kompjuterski kod, koji omogućava korisnicima da bez posrednika sigurno razmjenjuju vrijednost putem interneta.
Osnova cijelog sistema je blockchain, distribuisana digitalna knjiga koju održavaju hiljade nezavisnih računara (tzv. čvorova) širom svijeta. Svaka transakcija se bilježi u novi „blok“, koji se potom dodaje u lanac (otud naziv „lanac blokova“, odnosno blockchain). Informacija koja se jednom upiše u blok ne može da se izbriše, niti promijeni, što omogućava više transparentnosti i više povjerenja.
Da bi blockchain mreža u kojoj se sve to odvija zadržala to svojstvo, bitcoin koristi mehanizam konsenzusa nazvan dokaz rada (proof-of-work), što znači da specijalizovani računari koji „rudare“ bitcoin rješavaju kompleksne matematičke probleme kako bi omogućili obavljanje transakcija i pouzdanost mreže.
Deflatorna priroda bitcoina
Najjednostavniji način da se razumije deflatorna priroda bitcoina je da pogledamo cijene izražene u valuti kojoj plaćamo. Sigurno ste u posljednje vrijeme uhvatili sebe da komentarišete da ono što je prije nekoliko godina koštalo 10 eura danas košta 15 ili više. Budući da to ne zapažate kada je u pitanju cijena samo određenog proizvoda ili usluge, već kao sveprisutan trend, shvatate da se radi o tome da je novac izgubio vrijednost. Na primjer, kada je riječ o euru, otkako je Evropska centralna banka počela intenzivno da doštampava novac svake godine, pa je od 2009. kada je program tzv. „kvantitativnog popuštanja“ započet euro zabilježio kumulativnu inflaciju od 42,09% zbog povećane količine sredstava u opticaju.
Međutim, kada je riječ o bitcoinu, njega nikada neće biti više od 21 milion koliko je izdato prvog dana, a to nepromjenjivo pravilo zapisano je i u njegovom kodu. Ova ograničena ponuda oštro se suprotstavlja principima koji važe kod monetarnih institucija, poput centralnih banaka, koje doštampavaju novac, često da bi povećale količinu u opticaju i tako podstakle finansijske tokove, iako novac zbog toga gubi vrijednost. Nasuprot tome, bitcoin se zadržava na iznosu od 21 milion, pa je upravo ta konačnost osnova za njegovu deflatornu prirodu i mogućnost da vremenom dobija na vrijednosti.
Naravno, ovo ne znači da je cijena bitcoina predodređena da samo raste. Ona je zapravo prilično volatilna i oscilacije su česte, posebno ukoliko, na primjer, posmatramo odnos cijena unutar jedne godine ili nekoliko mjeseci, međutim, gledano sa vremenske distance od četiri do pet godina bilo koji uporedni period od nastanka bitcoina do danas upućuje na to da je cijena u međuvremenu porasla. Taj trend će se nastaviti, tako da, kao ni kada je riječ o drugim sredstvima, poput zlata ili nafte, nema mjesta konstatacijama da je „vrijeme niskih cijena prošlo“.
Šta zapravo znači ovaj dan?
Bitcoin Pizza Day je za mnoge prilika da saznaju ponešto novo o bitcoinu, jer tada imaju priliku da o njemu čuju detalje sa raznih strana, jer kako se ovaj događaj popularizuje stvaraju se i nove prilike za učenje. Takođe, ovaj dan od 2021. obilježavaju picerije širom svijeta, u više od 400 gradova iz najmanje 75 zemalja, jer je za mnoge ovo prilika da korisnike bitcoina navedu da potroše djelić svoje imovine na nešto iz njihove ponude. Naravno, taj iznos je danasd zanemarljivo mali, a cijena jedne pice danas je otprilike 0,00021 bitcoina.
No, dok picerije širom svijeta danas na zabavan način pokušavaju da dođu do novih gostiju, ovaj dan je za mnoge vlasnike bitcoina nešto poput opomene da svoje digitalne novčiće ipak ne treba trošiti na nešto potrošno, jer je budućnost nepredvidiva. Bitcoin Pizza Day je dan kada se ideja pretvorila u valutu, kada su linije koda postale sredstvo razmjene.
Prvi let avionom trajao je svega 12 sekundi, a u poređenju sa današnjim transkontinentalnim linijama to djeluje gotovo neuporedivo i čudno, međutim, od nečega je moralo početi. Porudžbina pice plaćene bitcoinom označile su početak razmjene ove vrste, dok se, na primjer, tokom jučerašnjeg dana obim plaćanja bitcoinom premašio 23 milijarde dolara. Nauka i tehnologija nas podsjećaju na to da sve počinje malim, zanemarivim koracima.

2025-05-23 22:01:31Ukraine is reportedly about to make history by becoming the first country in Europe to have a national bitcoin reserve, a move aimed at strengthening its economy during the war with Russia.
The plan is still in its early stages and Binance, the world’s largest digital asset exchange, is involved.
According to Incrypted, a Ukrainian digital asset news outlet, Ukrainian MP Yaroslav Zheleznyak, First Deputy Chairman of the Finance, Tax and Customs Policy Committee, confirmed that the draft law is almost ready and will be submitted to the parliament soon.
“We will soon submit a draft law from the industry allowing the creation of crypto reserves,” Zheleznyak told Incrypted.
Earlier discussions mentioned a broader “crypto reserve” but the current plan is focused on bitcoin as a strategic reserve asset. If approved, the law will allow the National Bank of Ukraine to hold bitcoin as part of the country’s official reserves.
Since the war with Russia started, Ukraine has become one of the most bitcoin-friendly countries in the world.
In 2022 and 2023 Ukraine raised over $100 million in digital asset donations for defense and humanitarian purposes. A report from Chainalysis ranked the country among the top 10 countries for bitcoin adoption globally.
A rather vague and unconfirmed report by BitcoinTreasuries.net states that “holdings of public officials” currently stand at 46,351 BTC.
Ukraine bitcoin holdings as reported by BitcoinTreasuries
Supporters of the bitcoin reserve say it will help Ukraine protect its economy from war-related instability, inflation and currency depreciation.
By going digital, the government is looking for modern tools to strengthen its financial system in uncertain times. This is not just about storing bitcoin, it’s about establishing clear laws for digital assets ownership, management and use.
Binance is playing an advisory role in the project. The company has worked with Ukraine on digital asset education and regulations in the past and is now helping to shape the legal framework for the bitcoin reserve.
Kirill Khomyakov, Binance’s regional head for Central and Eastern Europe, Central Asia and Africa, confirmed the company’s support, but warned it won’t be fast or easy.
“The creation of such a reserve will require significant changes in legislation,” Khomyakov said. “Another positive aspect is that this initiative will likely lead to greater clarity in the regulation of crypto assets in Ukraine.”
Despite the support from some officials, there are legal hurdles. Ukrainian laws don’t allow bitcoin to be in the official reserves. So the government needs to pass new laws for it to happen.
Efforts to legalize bitcoin in general have been going on for years. In 2021, a draft law on virtual assets was approved by Finance Committee but was withdrawn after the President’s Office and financial regulators objected.
Up to now, over 80 amendments have been proposed, showing how complicated the process is.
The Ministry of Digital Transformation is leading a larger reform that could introduce rules for digital asset exchanges, tax laws and anti-money laundering standards in the country.
Ukraine isn’t alone in considering bitcoin as a national reserve asset. In March 2025, the U.S. announced its own Strategic Bitcoin Reserve using BTC seized in criminal cases.

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. 🫡

2025-05-23 22:01:11I often hear "bitcoin doesn't interest me, I'm not a finance person."
Ironically, the beauty of sound money is you don't have to be. In the current system you're expected to manage a diversified investment portfolio or pay someone to do it. Bitcoin will make that optional.
— ODELL (@ODELL) September 16, 2018
At first glance bitcoin often appears overwhelming to newcomers. It is incredibly easy to get bogged down in the details of how it works or different ways to use it. Enthusiasts, such as myself, often enjoy going down the deep rabbit hole of the potential of bitcoin, possible pitfalls and theoretical scenarios, power user techniques, and the developer ecosystem. If your first touch point with bitcoin is that type of content then it is only natural to be overwhelmed. While it is important that we have a thriving community of bitcoiners dedicated to these complicated tasks - the true beauty of bitcoin lies in its simplicity. Bitcoin is simply better money. It is the best money we have ever had.
Life is complicated. Life is hard. Life is full of responsibility and surprises. Bitcoin allows us to focus on our lives while relying on a money that is simple. A money that is not controlled by any individual, company, or government. A money that cannot be easily seized or blocked. A money that cannot be devalued at will by a handful of corrupt bureaucrat who live hundreds of miles from us. A money that can be easily saved and should increase in purchasing power over time without having to learn how to "build a diversified stock portfolio" or hire someone to do it for us.
Bitcoin enables all of us to focus on our lives - our friends and family - doing what we love with the short time we have on this earth. Time is scarce. Life is complicated. Bitcoin is the most simple aspect of our complicated lives. If we spend our scarce time working then we should be able to easily save that accrued value for future generations without watching the news or understanding complicated financial markets. Bitcoin makes this possible for anyone.
Yesterday was Mother's Day. Raising a human is complicated. It is hard, it requires immense personal responsibility, it requires critical thinking, but mothers figure it out, because it is worth it. Using and saving bitcoin is simple - simply install an app on your phone. Every mother can do it. Every person can do it.
Life is complicated. Life is beautiful. Bitcoin is simple.
If you found this post helpful support my work with bitcoin.

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

2025-05-22 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.

2025-05-09 13:56:57Someone asked for my thoughts, so I’ll share them thoughtfully. I’m not here to dictate how to promote Nostr—I’m still learning about it myself. While I’m not new to Nostr, freedom tech is a newer space for me. I’m skilled at advocating for topics I deeply understand, but freedom tech isn’t my expertise, so take my words with a grain of salt. Nothing I say is set in stone.
Those who need Nostr the most are the ones most vulnerable to censorship on other platforms right now. Reaching them requires real-time awareness of global issues and the dynamic relationships between governments and tech providers, which can shift suddenly. Effective Nostr promoters must grasp this and adapt quickly.
The best messengers are people from or closely tied to these at-risk regions—those who truly understand the local political and cultural dynamics. They can connect with those in need when tensions rise. Ideal promoters are rational, trustworthy, passionate about Nostr, but above all, dedicated to amplifying people’s voices when it matters most.
Forget influencers, corporate-backed figures, or traditional online PR—it comes off as inauthentic, corny, desperate and forced. Nostr’s promotion should be grassroots and organic, driven by a few passionate individuals who believe in Nostr and the communities they serve.
The idea that “people won’t join Nostr due to lack of reach” is nonsense. Everyone knows X’s “reach” is mostly with bots. If humans want real conversations, Nostr is the place. X is great for propaganda, but Nostr is for the authentic voices of the people.
Those spreading Nostr must be so passionate they’re willing to onboard others, which is time-consuming but rewarding for the right person. They’ll need to make Nostr and onboarding a core part of who they are. I see no issue with that level of dedication. I’ve been known to get that way myself at times. It’s fun for some folks.
With love, I suggest not adding Bitcoin promotion with Nostr outreach. Zaps already integrate that element naturally. (Still promote within the Bitcoin ecosystem, but this is about reaching vulnerable voices who needed Nostr yesterday.)
To promote Nostr, forget conventional strategies. “Influencers” aren’t the answer. “Influencers” are not the future. A trusted local community member has real influence—reach them. Connect with people seeking Nostr’s benefits but lacking the technical language to express it. This means some in the Nostr community might need to step outside of the Bitcoin bubble, which is uncomfortable but necessary. Thank you in advance to those who are willing to do that.
I don’t know who is paid to promote Nostr, if anyone. This piece isn’t shade. But it’s exhausting to see innocent voices globally silenced on corporate platforms like X while Nostr exists. Last night, I wondered: how many more voices must be censored before the Nostr community gets uncomfortable and thinks creatively to reach the vulnerable?
A warning: the global need for censorship-resistant social media is undeniable. If Nostr doesn’t make itself known, something else will fill that void. Let’s start this conversation.

2025-05-23 22:01:07A 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.

2025-04-22 12:44:42Die Debatte um Migration, Grenzsicherung und Abschiebungen wird in Deutschland meist emotional geführt. Wer fordert, dass illegale Einwanderer abgeschoben werden, sieht sich nicht selten dem Vorwurf des Rassismus ausgesetzt. Doch dieser Vorwurf ist nicht nur sachlich unbegründet, sondern verkehrt die Realität ins Gegenteil: Tatsächlich sind es gerade diejenigen, die hinter jeder Forderung nach Rechtssicherheit eine rassistische Motivation vermuten, die selbst in erster Linie nach Hautfarbe, Herkunft oder Nationalität urteilen.
Das Recht steht über Emotionen
Deutschland ist ein Rechtsstaat. Das bedeutet, dass Regeln nicht nach Bauchgefühl oder politischer Stimmungslage ausgelegt werden können, sondern auf klaren gesetzlichen Grundlagen beruhen müssen. Einer dieser Grundsätze ist in Artikel 16a des Grundgesetzes verankert. Dort heißt es:
„Auf Absatz 1 [Asylrecht] kann sich nicht berufen, wer aus einem Mitgliedstaat der Europäischen Gemeinschaften oder aus einem anderen Drittstaat einreist, in dem die Anwendung des Abkommens über die Rechtsstellung der Flüchtlinge und der Europäischen Menschenrechtskonvention sichergestellt ist.“
Das bedeutet, dass jeder, der über sichere Drittstaaten nach Deutschland einreist, keinen Anspruch auf Asyl hat. Wer dennoch bleibt, hält sich illegal im Land auf und unterliegt den geltenden Regelungen zur Rückführung. Die Forderung nach Abschiebungen ist daher nichts anderes als die Forderung nach der Einhaltung von Recht und Gesetz.
Die Umkehrung des Rassismusbegriffs
Wer einerseits behauptet, dass das deutsche Asyl- und Aufenthaltsrecht strikt durchgesetzt werden soll, und andererseits nicht nach Herkunft oder Hautfarbe unterscheidet, handelt wertneutral. Diejenigen jedoch, die in einer solchen Forderung nach Rechtsstaatlichkeit einen rassistischen Unterton sehen, projizieren ihre eigenen Denkmuster auf andere: Sie unterstellen, dass die Debatte ausschließlich entlang ethnischer, rassistischer oder nationaler Kriterien geführt wird – und genau das ist eine rassistische Denkweise.
Jemand, der illegale Einwanderung kritisiert, tut dies nicht, weil ihn die Herkunft der Menschen interessiert, sondern weil er den Rechtsstaat respektiert. Hingegen erkennt jemand, der hinter dieser Kritik Rassismus wittert, offenbar in erster Linie die „Rasse“ oder Herkunft der betreffenden Personen und reduziert sie darauf.
Finanzielle Belastung statt ideologischer Debatte
Neben der rechtlichen gibt es auch eine ökonomische Komponente. Der deutsche Wohlfahrtsstaat basiert auf einem Solidarprinzip: Die Bürger zahlen in das System ein, um sich gegenseitig in schwierigen Zeiten zu unterstützen. Dieser Wohlstand wurde über Generationen hinweg von denjenigen erarbeitet, die hier seit langem leben. Die Priorität liegt daher darauf, die vorhandenen Mittel zuerst unter denjenigen zu verteilen, die durch Steuern, Sozialabgaben und Arbeit zum Erhalt dieses Systems beitragen – nicht unter denen, die sich durch illegale Einreise und fehlende wirtschaftliche Eigenleistung in das System begeben.
Das ist keine ideologische Frage, sondern eine rein wirtschaftliche Abwägung. Ein Sozialsystem kann nur dann nachhaltig funktionieren, wenn es nicht unbegrenzt belastet wird. Würde Deutschland keine klaren Regeln zur Einwanderung und Abschiebung haben, würde dies unweigerlich zur Überlastung des Sozialstaates führen – mit negativen Konsequenzen für alle.
Sozialpatriotismus
Ein weiterer wichtiger Aspekt ist der Schutz der Arbeitsleistung jener Generationen, die Deutschland nach dem Zweiten Weltkrieg mühsam wieder aufgebaut haben. Während oft betont wird, dass die Deutschen moralisch kein Erbe aus der Zeit vor 1945 beanspruchen dürfen – außer der Verantwortung für den Holocaust –, ist es umso bedeutsamer, das neue Erbe nach 1945 zu respektieren, das auf Fleiß, Disziplin und harter Arbeit beruht. Der Wiederaufbau war eine kollektive Leistung deutscher Menschen, deren Früchte nicht bedenkenlos verteilt werden dürfen, sondern vorrangig denjenigen zugutekommen sollten, die dieses Fundament mitgeschaffen oder es über Generationen mitgetragen haben.
Rechtstaatlichkeit ist nicht verhandelbar
Wer sich für eine konsequente Abschiebepraxis ausspricht, tut dies nicht aus rassistischen Motiven, sondern aus Respekt vor der Rechtsstaatlichkeit und den wirtschaftlichen Grundlagen des Landes. Der Vorwurf des Rassismus in diesem Kontext ist daher nicht nur falsch, sondern entlarvt eine selektive Wahrnehmung nach rassistischen Merkmalen bei denjenigen, die ihn erheben.

2025-05-23 22:01:06The 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.”

2025-05-20 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.

I found this recipe a couple years ago and have been addicted to it since. Its incredibly easy, and cheap to prep. Freeze the sausage in flat, single serving portions. That way it can be cooked from frozen for a fast, flavorful, and healthy lunch or dinner. I took inspiration from the video that contained this recipe, and almost always pan fry the frozen sausage with some baby broccoli. The steam cooks the broccoli and the fats from the sausage help it to sear, while infusing the vibrant flavors. Serve with some rice, if desired. I often use serrano peppers, due to limited produce availability. They work well for a little heat and nice flavor that is not overpowering.
Details
- ⏲️ Prep time: 25 min
- 🍳 Cook time: 15 min (only needed if cooking at time of prep)
- 🍽️ Servings: 10
Ingredients
- 4 lbs ground pork
- 12-15 cloves garlic, minced
- 6 Thai or Serrano peppers, rough chopped
- 1/4 c. lime juice

- Šta uzrokuje Inflaciju?
- Da li nam je infacija potrebna?
- Kako se meri inflacija?
- Da li inflacija pokreće ekonomski rast?
- Da li inflacija pokreće ili umanjuje nejednakost bogatstva?
- Gde se danas javlja inflacija?
- Šta je deflacija?
- Kakav uticaj inflacija ima na društvo?
Inflacija može da bude uznemirujuća tema, jer uključuje amorfni koncept novca. Međutim, inflacija je zapravo jednostavna tema koja je napravljena da bude složena razdvajanjem novca i drugih dobara. U ovom članku razlažemo inflaciju i njene uzroke.
Najjednostavnija definicija inflacije je rast cena dobara i usluga. Kada cene rastu, to takođe znači da vrednost jedinice novca – poput dolara – opada. Uzmimo primer McDonald’s hamburgera: 1955. ovaj skromni hamburger se prodavao za samo 15 centi. U 2018. godini se prodavao za 1,09 USD. U 2021. godini prodaje se za 2,49 USD – ogroman rast cene od 1650%.
To znači da je dolar izgubio dosta svoje vrednosti. 1955. godine mogli ste da kupite gotovo 7 hamburgera za novčanicu od jednog dolara. 2021. godine taj dolar vam ne bi kupio ni jedan hamburger. Zašto se čini da cene uvek rastu tokom vremena? I šta možete da učinite povodom toga? Ovaj članak ima za cilj da odgovori na ta pitanja.
Ekonomisti pokušavaju da sumiraju rast cena mnogih dobara i usluga kao jedan prosečan broj. Ovaj broj predstavlja promenu ukupnih troškova u godišnjim troškovima prosečnog potrošača, kao što su stanarina, hrana i gorivo.
U Sjedinjenim Državama ovaj broj je poznat kao Indeks Potrošačkih Cena, eng. Consumer Price Index (CPI). Kada se CPI poveća tokom određenog vremenskog perioda, ekonomisti kažu da imamo inflaciju. Kada se smanji, to se naziva deflacija.
Šta uzrokuje Inflaciju?
Mnogi izvori kažu da je stalna inflacija koju danas doživljavamo ili uzrokovana povećanjem potražnje (eng. demand-pull) ili smanjenjem ponude usled povećanih proizvodnih troškova (eng. cost-push).
Ovi razlozi nisu tačni – hajde da pogledamo zašto.
Da bismo razumeli pravi razlog inflacije, moramo da sagledamo dve vrste inflacije:
- Inflacija Cena: Cene vremenom rastu.
- Monetarna Inflacija: Količina valute u opticaju raste sa vremenom.
Prva, inflacija cena, retko se javlja tokom dužih perioda (decenije, vekovi) zbog povećane potražnje ili povećanih troškova. Zašto? Tržišta teže da se uravnoteže. Tokom istorije smo više puta videli da povećana potražnja za dobrom povećava njegovu cenu, što podstiče proizvođače da proizvode više tog dobra. Kada se ponuda poveća, cene se smanjuju.
Ovaj ciklus može da potraje nekoliko godina, i javlja se kod gotovo svake robe i „konačnog dobra“ (automobili, televizori, hrana itd.) na Zemlji. Izuzetak su retki metali poput zlata i srebra. Dokazi o tome su prikazani u nastavku.
Kada se poveća trošak za proizvodnju dobra, cena tog dobra često raste da bi pokrila te troškove. Ovaj rast cene dovodi do toga da potrošači tog dobra traže alternativu ili smanjuju potrošnju tog dobra, što dovodi do pada cena na prethodni nivo.
Tržište se prirodno uravnotežava, a cene se smanjuju ili povećanjem ponude ili smanjenjem potražnje.
Da li imamo dokaze da tržišta vremenom uravnotežuju ponudu i potražnju?
Podaci o cenama robe tokom vremena mogu nam dati bolje razumevanje da li tržišta zaista efikasno uravnotežuju ponudu i potražnju. Međutim, cene ne možemo da posmatramo u smislu nacionalnih valuta, jer naše vlade uvek štampaju više svojih nacionalnih valuta.
Oni sprovode monetarnu inflaciju, koja može da izazove inflaciju cena. Posmatranje tržišnih cena u smislu nacionalnih valuta, poput američkog dolara, je poput merenja visine lenjirom koji se neprestano smanjuje. Vaša visina u broju biće sve veća i veća, ali stvarna visina se ne menja.
Mi možemo da znamo da li tržišta uravnotežuju ponudu i potražnju gledajući cene dobara u smislu monetarnog dobra koje ima vrlo konzistentnu ponudu tokom vremena.
Vremenom se pokazalo da zlato ima najmanju monetarnu inflaciju od svih postojećih valuta i dobara. To čini zlato odličnim ‘lenjirom’ za merenje da li tržišta vremenom uravnotežuju ponudu i potražnju. Da bismo bolje razumeli inflaciju cena tokom vremena, pitaćemo koliko unci zlata nešto košta tokom vremena.
Cene u zlatu pokazuju nam da se tržišta vremenom uravnotežuju
Ako cene dobara posmatramo u obliku zlata, vidimo da cene robe prate srednje tačke tokom dužih vremenskih perioda.
Nafta, na primer, je vrlo nestabilna, ali ima tendenciju da se kreće oko 2,5 grama zlata po barelu.
WTI Sirova Nafta u gramima Zlata po Barelu
Cena nafte je promenljiva, ali tokom decenija ima tendenciju da se kreće po strani.
Cene kuća tokom proteklih 10 godina takođe su prilično stabilne, iako imamo fiksnu količinu zemlje na planeti. Vidimo da cene kuća u pogledu zlata imaju tendenciju da variraju oko indeksne cene od oko 80, prikazane na grafikonu.
Shiller-ov US indeks cena kuća u USD i zlatu
Ovaj grafikon je na logaritamskoj skali, što nam omogućava da vizualizujemo zapanjujuća povećanja u zelenoj liniji, koja predstavlja domove u dolarima.
Grafički izražene u američkim dolarima, cene ovih dobara uvek rastu – baš kao i McDonald’s hamburger. Da su povećana potražnja ili povećani troškovi odgovorni za konstantnu inflaciju cena, takođe bismo videli kako se cena ove robe povećava u smislu zlata. Podaci iznad pokazuju da su cene konstantne.
Moraju da postoje i drugi razlozi za upornu inflaciju cena koju smo videli u dolarskim iznosima tokom proteklog veka.
Evo šta znamo o tome šta dugoročno utiče na cene, kao u periodu od 1955. do 2018. godine:
- Rast produktivnosti uzrokovan inovacijama, što dovodi do pada cena tokom vremena
- Monetarna inflacija – štampanje velikih količina valute – koja uzrokuje porast cena denominovanih u toj valuti tokom vremena
Znamo da cene izražene u dolarima, eurima i ostalim valutama neprestano rastu. Ako ne mislimo da naša produktivnost kao društva ide unazad, postoji samo jedan jednostavan razlog za inflaciju cena: štampanje većih količina valute, iliti monetarna inflacija.
Naše vlade i banke su zapravo prilično iskrene u pogledu zapanjujućih količina valute koje štampaju. Oni nam svakodnevno govore da oni uzrokuju monetarnu inflaciju.
Da li nam je infacija potrebna?
Bez uporne monetarne inflacije (koja uzrokuje inflaciju cena), naša celokupna savremena ekonomija bi se srušila.
Dozvolite da vam objasnim. Sledeći odeljak može da bude šokantan, i ohrabrujem vas da i sami istražite ukoliko mislite da nisam u pravu.
Kada centralne banke i komercijalne banke daju zajmove, one stvaraju novu valutu.
Kada centralne banke daju zajmove vladama “kupujući državni dug”, one stvaraju novu valutu kada to urade. To omogućava vladama da vode budžetski deficit trošeći više nego što uzimaju od poreza. U tom procesu državni dug se nagomilava.
Komercijalne banke stvaraju novu valutu kada daju zajmove fizičkim licima i preduzećima. Jedino ograničenje koliko novog novca mogu da stvore je zakonski zahtev da banka ima na raspolaganju određeni procenat od ukupnog iznosa novca koji su ljudi deponovali. Zbog toga je naš bankarski sistem poznat kao delimična rezerva – banke pri ruci moraju da imaju samo deo vašeg novca.
Stvaranje valute je neophodno da bi održalo sistem u životu
Budući da se svi zajmovi uglavnom sastoje od novostvorene valute, mora se stvoriti još više valute da bi se taj dug otplatio. A evo i zašto:
Recimo da su prošle godine sve svetske kreditne aktivnosti dovele do stvaranja 100 milijardi dolara. Svih tih 100 milijardi dolara je novostvoreno, i one se duguju bankama sa nekom dodatnom vrednošću za kamate. Odakle dolazi ova dodatna valuta za plaćanje kamata? Budući da ovde govorimo o celokupnoj svetskoj ekonomiji, to plaćanje kamata mora da dodje iz nove količine novostvorene valute.
Sve jedinice današnjih valuta nastale su pozajmljivanjem, a isplata kamate na te zajmove znači da moramo stalno da stvaramo još više nove valute. To dovodi do beskrajne monetarne inflacije. Kada nova valuta cirkuliše kroz ekonomiju, to dovodi do porasta cena: inflacije cena.
Previše monetarne inflacije može dovesti do hiperinflacije cena. U Venecueli je krajem 2018. godine piletina koštala preko 14 miliona Bolivara. Izvor: NBC News
Monetarni sistem se raspada ako se ova monetarna inflacija zaustavi, jer bi to značilo da veliki broj onih koji su uzeli zajam širom sveta ne bi mogao da vrati novac koji su pozajmili – oni ne bi izmirili svoje dugove.
Banke ili zajmodavci koji drže dug tada bi imali bezvrednu imovinu. Budući da vrednost duga podupire vrednost valute, vrednost valute bi strmoglavo padala zajedno sa dugom.
Kada ljudi izgube poverenje u ’tradicionalnu’ valutu, ona brzo postane bezvredna. To se dogodilo u Nemačkoj nakon Prvog svetskog rata, u Peruu devedesetih, Jugoslaviji 1994. ,Zimbabveu, Venecueli i sa još bezbroj drugih tradicionalnih valuta. Da bi odložile ovaj neizbežni ishod dokle god mogu, centralne banke jačaju poverenje u sistem nastavljajući da štampaju valutu stabilnim kursom.
Ovo osigurava da većina ljudi koju su uzeli zajam ima valutu za otplatu svojih kredita. Upravo to se dešava kada vlada izvrši „spas“ kao 2008. ili 2020. – oni osiguravaju da svi imaju dovoljno novca za plaćanje dugova, tako da laž može da se nastavi.
Inflacija ne dolazi iz povećanja potražnje
Sa više valute u opticaju, monetarna inflacija može da izgleda kao povećanje potražnje. Međutim, ekonomisti koji kažu da povećana potražnja pokreće stabilnu inflaciju tokom decenija propuštaju suptilnu poentu: iako monetarna inflacija može da prouzrokuje veću potrošnju, to nije zato što su ljudi zaista bogatiji, već zato što veruju da su bogatiji.
Kada se puno novca ubrizga u ekonomiju, cene jednostavno rastu jer više valute pokriva istu količinu robe. Rast cena znači pad vrednosti valute, tako da nema realnog povećanja stvarnog bogatstva, iako ljudi možda “troše više” u nominalnom iznosu valute.
Uzmimo ovaj primer: vi mesečno zarađujete 1.500 EUR, i prema svom trenutnom načinu života vi mesečno trošite oko 1.500 EUR. Dolazi vlada i počinje da vam daje dodatnih 500 EUR svakog meseca – vi se osećate poprilično dobro, zar ne? Sada možete da izlazite češće u restoran.
Međutim, vlada daje svima po 500 EUR mesečno, i svi ostali takođe troše taj novac. Ekonomista u vladinoj kancelariji, vidi da sada svi troše tih dodatnih 500 EUR mesečno i zaključuje da je vlada ‘stimulisala ekonomiju’.
Ipak, kako sav taj dodatni novac kruži ekonomijom, cene prirodno rastu. Sada vam je potrebno 2.000 EUR da biste održali svoj trenutni način života.
Da li si nešto bogatiji?
Vi možda imate više eura na vašem bankovnom računu, ali svaki od njih vam kupuje manje. Sada trošite 2.000 EUR mesečno da biste živeli životnim stilom koji vas je nekada koštao samo 1.500 EUR mesečno.
Ovo je ono što monetarna inflacija radi, i zašto je toliko pametnih ekonomista zavarano da misle da povećana potražnja, radije nego štampanje novca, pokreće trajnu inflaciju cena.
Da li smo uvek imali inflaciju?
Stalna inflacija cena relativno je nedavna pojava u modernim ekonomijama i započela je u vreme kada su Sjedinjene Države počele da konstantno štampaju valutu. Ako bi promene ponude i potražnje zaista dugoročno uzrokovale inflaciju cena, videli bismo inflaciju cena tokom istorije. Podaci govore drugačiju priču.
Indeks potrošačkih cena, koji se povećava kada imamo inflaciju cena, bio je prilično konstantan pre početka našeg trenutnog tradicionalnog ’fiat’ monetarnog sistema.
Taj sistem je započeo Bretton Woods-ovim sporazumom iz 1945. godine, a ubrzao se kada je Nixon 1971. okončao svetski zlatni standard.
Indeks potrošačkih cena, Sjedinjene Države, 1790-2015
Kako se meri inflacija?
Inflacija cena se često prikazuje kao promena indeksa potrošačkih cena (CPI). CPI je prosek cena raznih dobara koje ljudi kupuju u svakodnevnom životu: hrane, goriva, stanovanja itd. U Sjedinjenim Državama, vladin odsek pod nazivom Biro za statistiku rada (BLS) meri promene cena. To rade tako što posećuju maloprodajne radnje, beleže cene, računaju prosek i izveštavaju godišnju inflaciju kao promenu u odnosu na prošlu godinu.
Stopa inflacije koja se izveštava, je važna svima jer se koristi za određivanje povećanja troškova života i socijalnih davanja, poput plaćanja socijalnog osiguranja. Kada se CPI prilagodi naniže, isplate zarada i naknada su manje nego što bi trebalo da budu.
Efekti su se vremenom sjedinili: osoba koja u svojoj prvoj godini rada zaradi 40.000 USD zarađivaće samo 52.000 USD u svojoj desetoj godini staža, sa povećanim troškovima života od 3% da bi se plata podudarala sa inflacijom. Ako bi vlada umesto toga prijavila inflaciju od 6%, ta osoba bi u svojoj desetoj godini zarađivala 67.500 USD – tj. oko 30% više. Način na koji izračunavamo i prijavljujemo inflaciju ima ogroman uticaj na zaradu većine zaposlenih i građana.
Ovo je inflacija (procentualna promena u CPI) izmerena u poslednjih 20 godina u Sjedinjenim Državama:
Prvobitno je BLS jednostavno beležio cenu korpe robe široke potrošnje svake godine. Međutim, istraživanje Boskinove Komisije 1996. godine dovelo je do novih alata koji Birou za statistiku rada omogućavaju prilagođavanje cena u CPI. Dva najvažnija alata su geometrijsko ponderisanje i hedonika.
Geometrijsko Ponderisanje
Geometrijsko ponderisanje znači da kupovne navike sada mogu da utiču na to koliko promena cene pojedinog dobra utiče na CPI. Ako potrošači kupe manje robe, ona ima manju težinu kada se ubaci u presek indeksa potrošačkih cena. Boskinova Komisija je tvrdila da bi ova promena pomogla da se promene sklonosti potrošača. Međutim, ne postoji način da se utvrdi da li ljudi menjaju svoje kupovne navike jer zapravo žele da kupuju različite stvari. Vrlo je moguće da ljudi kupuju manje određenog dobra jer ono raste u ceni. Stoga geometrijsko ponderisanje uzrokuje da roba sa velikim rastom cena ima manje uticaja na CPI, što dovodi do niže prijavljene inflacije.
Hedonika
Hedonika omogućava Birou za statistiku rada da menja cenu dobra na osnovu njegovog opaženog povećanja ‘korisnosti’ tokom vremena. Evo primera: recimo da se televizor sa rezolucijom od 720p 2009. godine prodavao za 200 USD. U 2010. godini isti model televizora sada ima rezoluciju od 1080p i prodaje se po istoj ceni: 200 USD. Međutim, pošto se tehnologija u televizoru poboljšala, zaposleni u Birou za statistiku rada mogu da izmisle ‘korisni’ broj i pomoću njega oduzmu deo vrednosti od cene televizora. Kao rezultat, BLS može da kaže da TV košta 180 USD u 2010. godini – iako je njegova cena 200 USD. Ovo dovodi do pada prijavljene inflacije.
Oba ova prilagođavanja smanjuju prijavljenu stopu inflacije, što smanjuje povećanje troškova života i isplate naknada za socijalno osiguranje. Koliko ta prilagođavanja inflacije pogađaju radničku klasu i penzionere? Neke procene, poput procena ekonomiste John Williams-a, sa koledža u Darmouthu, stavljaju stvarnu inflaciju u SAD na u proseku 3% – 6% više nego što je izveštavano od strane Bira za statistiku rada. To bi inflaciju u 2020 dovelo do 5% – 8%, umesto na prijavljenih 2%.
U 2021. godini prijavljena inflacija je 5.4%, u prvom kvartalu.
Da li inflacija pokreće ekonomski rast?
Mnogi ljudi veruju da stabilna inflacija pokreće ekonomski rast podstičući investicije i potrošnju umesto štednje. Međutim, osnovni ekonomski podaci pobijaju ovu uobičajenu tvrdnju.
Ako za primer uzmemo Sjedinjene Države, nacija je imala samo kratke periode inflacije od 1775. do oko 1950. godine, kao što pokazuje indeks potrošačkih cena koji je ostao nepromenjen. Inflacija dobija zamah tek nakon 1971. godine, pa bi bilo za očekivati da će i stopa rasta bruto domaćeg proizvoda (BDP) Sjedinjenih Država porasti nakon 1971. godine.
Indeks potrošačkih cena, Sjedinjene Države, 1790-2015
Međutim, vidimo da se bruto domaći proizvod (BDP) po stanovniku u Sjedinjenim Državama, uobičajena mera ekonomske snage, neprekidno povećavao od 1820. godine do danas po stopi od oko 1,85% godišnje. Ne postoji porast oko 1971. godine, uprkos rastućoj inflaciji koja je započela u to vreme.
Ovo je logaritamski grafikon, koji nam omogućava da bolje vizualizujemo rast tokom vremena: što više logaritamski grafikon podseća na pravu liniju, to je stopa promene konzistentnija. Za više detalja, ovde pogledajte naslov: Rast na tehnološkoj granici i rast dostizanja.
To pokazuje da inflacija ne pokreće ekonomski rast.
Nažalost, imamo dokaze da inflacija ima i druge neželjene posledice, poput nejednakosti bogatstva. Koncentracija bogatstva u top 1%, počela je da raste krajem 1970-ih, nekoliko godina nakon što su Sjedinjene Države skinule svet sa zlatnog standarda i pretvorile se u monetarni sistem zasnovan na dugovima koji zahteva monetarnu inflaciju, a time i inflaciju cena, da bi preživeo.
Za potpunu istoriju tranzicije novca sa robnog sistema na dužni sistem, pročitajte naš članak o novcu.
Da li inflacija pokreće ili umanjuje nejednakost bogatstva?
Veza između inflacije i nejednakosti bogatstva postaje jasna kada pogledamo kako novostvorena valuta ulazi u ekonomiju. Vlade, komercijalne banke, velike korporacije i bogati često koriste kredite da bi iskoristili prednosti svojih moći. Kada podignu kredite, oni novonastalu valutu dobijaju ranije od svih ostalih. Oni imaju koristi od inflacije trošenjem nove valute pre nego što cene počnu da rastu kao rezultat te nove valute koja kruži u ekonomiji. Veliki i bogati subjekti često mogu da dobiju kredite po nižim troškovima od prosečnog građanina ili malog preduzeća. To znači da mogu da povećaju svoje poslovanje i bogatstvo brže od manjih firmi.
Bogati mogu da dobiju jeftine zajmove, zahvaljujući Federalnim Rezervama koje zadržavaju niske kamatne stope. To im omogućava da koriste ovo prednost za ostvarivanje ogromne dobiti.
Inflacija pogadja one koji rade za platu i ne mogu da ulože veći deo svog prihoda. Zarade se polako menjaju, ponekad se uskladjuju samo jednom godišnje. Kao rezultat, cene osnovnih dobara i usluga često rastu mnogo pre nego što zarade porastu. Cena potrošačke korpe takođe se smanjuje sa manipulacijama indeksom potrošačkih cena (CPI) koji skriva rast inflacije.
Gde se danas javlja inflacija?
Rekordno visoka inflacija javlja se u zemljama kao što su Venecuela, Zimbabve, Turska, Iran, Kuba, Južna Afrika i Argentina. To dovodi do sloma trgovine i političke nestabilnosti.
U razvijenom svetu vlade izveštavaju o niskoj inflaciji cena. Međutim, globalni bankarski sistem stvara nove valute u tonama – u toku je velika monetarna inflacija. Centralne banke dovode do sve većeg stvaranja valuta snižavanjem kamatnih stopa. To dovodi do toga da korporacije i pojedinci mogu da uzimaju jeftinije kredite, a svaki kredit znači stvaranje nove valute. Od 2008. godine, gotovo sve glavne centralne banke postavile su kamatne stope blizu nule.
Mnoge centralne banke takođe su pozajmljivale ogromne iznose vladama i bankama koje su propale nakon finansijske krize 2008. godine. Za samo nekoliko meseci, ovo je udvostručilo (ponekad utrostručilo ili učetvorostručilo) novčanu masu mnogih nacija. Oni su ovo nazvali „kvantitativno ublažavanje“.
Ako banke koriste toliku monetarnu inflaciju, zašto onda mi ne vidimo inflaciju cena?
Jednostavno rečeno, većina nove valute nije dospela u ruke običnih ljudi. Kada obični ljudi budu mogli da potroše novoštampanu valutu na svoje svakodnevne potrebe, tada ćemo videti rast CPI i inflacije.
Danas većina valuta ulazi u svet putem bankarskih zajmova, pa banke igraju veliku ulogu u tome gde se dešava inflacija. Banke prvenstveno pozajmljuju vrlo ‘sigurnim’ klijentima poput bogatih pojedinaca, vlada i velikih korporacija. Ovi subjekti kupuju luksuznu robu, umetnička dela, finansijsku imovinu i državne obveznice.
Cene ovih vrsta imovine nisu uključene u CPI, tako da je prijavljena inflacija niska. Kao rezultat, povećanje plata i isplate socijalnog osiguranja su takođe na niskom nivou.
Bogati su uživali u periodu od 2008. do 2021. godine, kada je njihova imovina upumpavana sa velikom količinom novog novca proizvedenog od bankarskih kredita!
Šta se dešava kada nova valuta dodje u ruke običnih ljudi?
Nažalost, jednog dana će sva ova nova valuta da uđe u normalnu ekonomiju i time će se povećati cene svakodnevne robe. To je poćelo da se dešava 2021. godine kao rezultat stimulativnih programa COVID-19 u Sjedinjenim Državama, koji su ljudima distribuirali trilione dolara. Iako je ovo zasigurno poželjnije od spašavanja korporacija, svaka vrsta spašavanja koja uključuje štampanje novca ima gadne dugoročne efekte.
Ovo što sada doživljavamo dogodilo se u Nemačkoj tokom i posle Prvog svetskog rata. Cene u Nemačkoj su zapravo pale tokom Prvog svetskog rata uprkos velikom stvaranju valute od strane Nemačke centralne banke. Nisko poverenje u ekonomiju sprečavalo je nemački narod da troši novac. Međutim, kad se rat završio i kada su ljudi ponovo počeli da ga troše, cene su vrlo naglo skočile i valuta je postala bezvredna. To bi moglo da se dogodi 2020-ih u Sjedinjenim Državama, sa obzirom na predložene programe podsticaja.
Politike poput Univerzalnog Osnovnog Dohotka, eng. Universal Basic Income (UBI), koje izgledaju pogodne za njihova obećanja da će “spasiti ljude”, takođe mogu da pokrenu hiperinflaciju. Obični ljudi bi se osećali imućnije, trošili bi svoju novoštampanu valutu i doveli do brzog rasta cena. Ovo bi u suštini poništilo pozitivan uticaj građana koji dobijaju “besplatan novac” svakog meseca.
Pa kako onda vi možete da zaštitite svoju ušteđevinu od inflacije? Kupujte imovinu koja je retka, potcenjena i koju vlade teško mogu da prigrabe. Ova imovina su plemeniti metali poput zlata, i Bitcoin.
Šta je deflacija?
Deflacija znači pad cena tokom vremena. Mnogi ekonomisti kažu da će ovo dovesti do toga da ljudi gomilaju valutu i da će dovesti do ekonomskog kolapsa, jer ljudi prestaju da kupuju robu i ulažu u preduzeća. To jednostavno nije tačno, jer ljudi uvek imaju potrebe i želje zbog kojih kupuju odredjenu robu. Stalni pad cena tokom vremena jednostavno bi promenio psihologiju potrošačke kulture u kojoj živimo.
Potrošačka kultura potiče od inflacije
Kako je to istina? Pogledajmo na sledećem primeru. Recimo da želite novi auto i da imate dovoljno novca da ga kupite. Poznato je da u našem svetu zbog stalne inflacije vaš novac vremenom postaje sve manje i manje vredan. U paralelnom svemiru u kojem se javlja stalna deflacija, vaš novac vremenom postaje sve vredniji.
- Uz konstantnu inflaciju, auto će koštati nešto više sledeće godine, i nešto više naredne godine. Niste sigurni gde da uložite novac da biste sa vremenom sigurno očuvali njegovu kupovnu moć. Ako niste sigurni da li ćete da kupite auto, ima više finansijskog smisla da ga kupite odmah, da biste dobili najbolju ponudu.
- Uz konstantnu deflaciju, auto će koštati nešto manje sledeće, i još manje naredne godine. Ako samo čuvate vaš novac, sledeće godine ćete dobiti bolju ponudu za auto. Ako niste sigurni da li ćete da kupite auto, ima više finansijskog smisla da sačekate malo duže da biste dobili bolju ponudu.
Sada razmislite o ta dva scenarija, pomnožena bilionima ljudi i proizvoda. Uz konstantnu inflaciju, svako ima malo više razloga da kupuje stvari upravo sada. Uz konstantnu deflaciju, svi sada imaju malo manje razloga da kupuju. Upravo na taj način inflacija je u osnovi naše materijalističke, potrošačke kulture. Deflacija bi mogla da bude lek.
Inflacija uzrokuje loše investicije
Vaš novac godišnje gubi “2%” svoje vrednosti zbog inflacije. Sada, recimo da vas Stefan pita da investirate u njegov Fast food. Nakon uvida u brojeve, verujete da ćete ovom investicijom izgubiti 1% od vrednosti svog novca. Gubitak od 1% u Stefanovom poslu bolji je od gubitka od 2% zbog inflacije, pa se vi odlučujete da uložite. Ovo je loša investicija, eng. malinvestment – investirajući vi ćete da izgubite deo vrednosti. Međutim, čuvanje valute je još gore, zato ulažete.
Mnogi investitori, poput penzijskih fondova, danas su prisiljeni da investiraju u neprofitabilne biznise zbog investicionih mandata i same veličine njihove ‘imovine pod upravljanjem’.
Pristalice konstantno niske inflacije veruju da bi deflacija smanjila investicije. Međutim, to bi samo smanjilo ulaganje u preduzeća sa negativnim očekivanim prinosom poput Stefanovog Fast food-a. Na primer, recimo da je deflacija u proseku oko 2% godišnje. Na ovom tržištu investitori bi jednostavno prestali da ulažu u projekte za koje misle da će im zaraditi manje od 2% godišnjeg povrata ulaganja.
Neznatno deflaciona valuta obeshrabriće ulaganja u lažna i loša preduzeća i podstaći ulaganje u solidna preduzeća koja svetu dodaju vrednost.
Kakav uticaj inflacija ima na društvo?
Inflacija pokreće povećanu potrošnju, smanjenu štednju i povećani dug. Sve ove stvari dovode do toga da većina ljudi mora da radi više sati i duže u starosti. Iako inflacija kažnjava one koji rade za platu, ona obogaćuje vlasnike bilo koje imovine koja dobija na ceni kada nova valuta uđe u sistem. Ova imovina uključuje akcije, umetnička dela, nekretnine i drugu imovinu koju bogataši koriste za čuvanje svog bogatstva.
Vremenom ljudi i firme izmišljaju nove načine za jeftinije stvaranje dobara i usluga višeg kvaliteta. Ovo je poznato kao ‘rast produktivnosti’ i trebalo bi da uzrokuje da cene tokom vremena konstantno padaju, a ne da rastu. Samo konstantno stvaranje valute koje je neophodno zbog monetarnog sistema zasnovanog na dugu naše vlade uzrokuje stalnu inflaciju i njene loše efekte.
Ako vam se sviđa moj rad, molim vas da ga podelite sa svojim prijateljima i porodicom. Cilj mi je da svima pružim pogled u ekonomiju i na to kako ona utiče na njihov život.

2025-05-23 20:31:44It's time to secure user data in your identity system This post was also published with the Industry Association of Privacy Professionals.
It seems like every day there is a new report of a major personal data breach. In just the past few months, Neiman Marcus, Ticketmaster, Evolve Bank, TeamViewer, Hubspot, and even the IRS have been affected.
The core issue is that user data is commonly spread across multiple systems that are increasingly difficult to fully secure, including database user tables, data warehouses and unstructured documents.
Most enterprises are already running an incredibly secure and hardened identity system to manage customer login and authorization, commonly referred to as a customer identity access management system. Since identity systems manage customer sign-up and sign-in, they typically contain customer names, email addresses, and phone numbers for multifactor authentication. Commercial CIAMs provide extensive logging, threat detection, availability and patch management.
Identity systems are highly secure and already store customers' personally identifiable information, so it stands to reason enterprises should consider identity systems to manage additional PII fields.
Identity systems are designed to store numerous PII fields and mask the fields for other systems. The Liberty Project developed the protocols that became Security Assertion Markup Language 2.0, the architecture at the core of CIAM systems, 20 years ago, when I was its chief technology officer. SAML 2.0 was built so identity data would be fully secure, and opaque tokens would be shared with other systems. Using tokens instead of actual user data is a core feature of identity software that can be used to fully secure user data across applications.
Most modern identity systems support adding additional customer fields, so it is easy to add new fields like Social Security numbers and physical addresses. Almost like a database, some identity systems even support additional tables and images.
A great feature of identity systems is that they often provide a full suite of user interface components for users to register, login and manage their profile fields. Moving fields like Social Security numbers from your database to your identity system means the identity system can fully manage the process of users entering, viewing and editing the field, and your existing application and database become descoped from managing sensitive data.
With sensitive fields fully isolated in an identity system and its user interface components, the identity system can provide for cumbersome and expensive compliance with standards such as the Health Insurance Portability and Accountability Act for medical data and the Payment Card Industry Data Security Standard for payment data, saving the time and effort to achieve similar compliance in your application.
There are, of course, applications that require sensitive data, such as customer service systems and data warehouses. Identity systems use a data distribution standard called System for Cross-domain Identity Management 2.0 to copy user data to other systems. The SCIM is a great standard to help manage compliance such as "right to be forgotten," because it can automatically delete customer data from other systems when a customer record is deleted from the identity system.
When copying customer data from an identity system to another application, consider anonymizing or masking fields. For example, anonymizing a birthdate into an age range when copying a customer record into a data warehouse can descope the data warehouse from containing personal information.
Most enterprises already run an Application Programming Interface Gateway to manage web services between systems. By combining an API Gateway with the identity system's APIs, it becomes very easy to automatically anonymize and mask customer data fields before they are copied into other systems.
A new set of companies including Baffle, Skyflow, and Piiano have introduced services that combine the governance and field management features of an identity system with extensive field masking. Since these systems do not offer the authentication and authorization features of an identity system, it's important to balance the additional features as they introduce an additional threat surface with PII storage and permissions.
PII sprawl is an increasing liability for companies. The most secure, compliant and flexible central data store to manage PII is the existing CIAM and API Gateway infrastructure that enterprises have already deployed.
Move that customer data into your identity system and lock it down. https://peter.layer3.press/articles/3c6912eb-404a-4630-9fe9-fd1bd23cfa64

2025-03-18 17:16:50Nun da das deutsche Bundesregime den Ruin Deutschlands beschlossen hat, der sehr wahrscheinlich mit dem Werkzeug des Geld druckens "finanziert" wird, kamen mir so viele Gedanken zur Geldmengenausweitung, dass ich diese für einmal niedergeschrieben habe.
Die Ausweitung der Geldmenge führt aus klassischer wirtschaftlicher Sicht immer zu Preissteigerungen, weil mehr Geld im Umlauf auf eine begrenzte Menge an Gütern trifft. Dies lässt sich in mehreren Schritten analysieren:
1. Quantitätstheorie des Geldes
Die klassische Gleichung der Quantitätstheorie des Geldes lautet:
M • V = P • Y
wobei:
- M die Geldmenge ist,
- V die Umlaufgeschwindigkeit des Geldes,
- P das Preisniveau,
- Y die reale Wirtschaftsleistung (BIP).Wenn M steigt und V sowie Y konstant bleiben, muss P steigen – also Inflation entstehen.
2. Gütermenge bleibt begrenzt
Die Menge an real produzierten Gütern und Dienstleistungen wächst meist nur langsam im Vergleich zur Ausweitung der Geldmenge. Wenn die Geldmenge schneller steigt als die Produktionsgütermenge, führt dies dazu, dass mehr Geld für die gleiche Menge an Waren zur Verfügung steht – die Preise steigen.
3. Erwartungseffekte und Spekulation
Wenn Unternehmen und Haushalte erwarten, dass mehr Geld im Umlauf ist, da eine zentrale Planung es so wollte, können sie steigende Preise antizipieren. Unternehmen erhöhen ihre Preise vorab, und Arbeitnehmer fordern höhere Löhne. Dies kann eine sich selbst verstärkende Spirale auslösen.
4. Internationale Perspektive
Eine erhöhte Geldmenge kann die Währung abwerten, wenn andere Länder ihre Geldpolitik stabil halten. Eine schwächere Währung macht Importe teurer, was wiederum Preissteigerungen antreibt.
5. Kritik an der reinen Geldmengen-Theorie
Der Vollständigkeit halber muss erwähnt werden, dass die meisten modernen Ökonomen im Staatsauftrag argumentieren, dass Inflation nicht nur von der Geldmenge abhängt, sondern auch von der Nachfrage nach Geld (z. B. in einer Wirtschaftskrise). Dennoch zeigt die historische Erfahrung, dass eine unkontrollierte Geldmengenausweitung langfristig immer zu Preissteigerungen führt, wie etwa in der Hyperinflation der Weimarer Republik oder in Simbabwe.

@ dfa02707:41ca50e3
2025-05-23 22:00:51Good morning (good night?)! The No Bullshit Bitcoin news feed is now available on Moody's Dashboard! A huge shoutout to sir Clark Moody for integrating our feed.
Headlines
- Spiral welcomes Ben Carman. The developer will work on the LDK server and a new SDK designed to simplify the onboarding process for new self-custodial Bitcoin users.
- The Bitcoin Dev Kit Foundation announced new corporate members for 2025, including AnchorWatch, CleanSpark, and Proton Foundation. The annual dues from these corporate members fund the small team of open-source developers responsible for maintaining the core BDK libraries and related free and open-source software (FOSS) projects.
- Strategy increases Bitcoin holdings to 538,200 BTC. In the latest purchase, the company has spent more than $555M to buy 6,556 coins through proceeds of two at-the-market stock offering programs.
- Spar supermarket experiments with Bitcoin payments in Zug, Switzerland. The store has introduced a new payment method powered by the Lightning Network. The implementation was facilitated by DFX Swiss, a service that supports seamless conversions between bitcoin and legacy currencies.
- The Bank for International Settlements (BIS) wants to contain 'crypto' risks. A report titled "Cryptocurrencies and Decentralised Finance: Functions and Financial Stability Implications" calls for expanding research into "how new forms of central bank money, capital controls, and taxation policies can counter the risks of widespread crypto adoption while still fostering technological innovation."
- "Global Implications of Scam Centres, Underground Banking, and Illicit Online Marketplaces in Southeast Asia." According to the United Nations Office on Drugs and Crime (UNODC) report, criminal organizations from East and Southeast Asia are swiftly extending their global reach. These groups are moving beyond traditional scams and trafficking, creating sophisticated online networks that include unlicensed cryptocurrency exchanges, encrypted communication platforms, and stablecoins, fueling a massive fraud economy on an industrial scale.
- Slovenia is considering a 25% capital gains tax on Bitcoin profits for individuals. The Ministry of Finance has proposed legislation to impose this tax on gains from cryptocurrency transactions, though exchanging one cryptocurrency for another would remain exempt. At present, individual 'crypto' traders in Slovenia are not taxed.
- Circle, BitGo, Coinbase, and Paxos plan to apply for U.S. bank charters or licenses. According to a report in The Wall Street Journal, major crypto companies are planning to apply for U.S. bank charters or licenses. These firms are pursuing limited licenses that would permit them to issue stablecoins, as the U.S. Congress deliberates on legislation mandating licensing for stablecoin issuers.
"Established banks, like Bank of America, are hoping to amend the current drafts of [stablecoin] legislation in such a way that nonbanks are more heavily restricted from issuing stablecoins," people familiar with the matter told The Block.
- Charles Schwab to launch spot Bitcoin trading by 2026. The financial investment firm, managing over $10 trillion in assets, has revealed plans to introduce spot Bitcoin trading for its clients within the next year.
Use the tools
- Bitcoin Safe v1.2.3 expands QR SignMessage compatibility for all QR-UR-compatible hardware signers (SpecterDIY, KeyStone, Passport, Jade; already supported COLDCARD Q).

- Šta je novac, i zašto trebate da brinete?
- Efikasnija Ušteda Novca
- Zasluge
- Molim vas da šerujete!
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.
Potrebno je puno obuke da bi izrezali dijamant.
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.
Svaka je jedinstvena na svoj način.
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.
Novac star 5000 godina VS novac star 13 godina
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.
Mnogo opcija, sve u istoj obračunskoj jedinici.
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.
Nije sjajna forma novca.
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.
Traženje zlata je spora i teška aktivnost. Obično se ne pronađe puno!
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.
Perle proizvedene u Gani
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.
Peć za izradu stakla u Muranu, Italija. Ovo ostrvo izvan Venecije proizvodi staklo od 15. veka.
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 (Udeo u ukupnom prihodu pre oporezivanja u domaćinstvima sa najvišim dohotkom (uključujući kapitalne dobitke), 1913-2018)
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.

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.

2025-05-21 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!

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.

2025-05-23 22:00:30The 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

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

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 .

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.

2025-05-15 15:31:45Capitalism is the most effective system for scaling innovation. The pursuit of profit is an incredibly powerful human incentive. Most major improvements to human society and quality of life have resulted from this base incentive. Market competition often results in the best outcomes for all.
That said, some projects can never be monetized. They are open in nature and a business model would centralize control. Open protocols like bitcoin and nostr are not owned by anyone and if they were it would destroy the key value propositions they provide. No single entity can or should control their use. Anyone can build on them without permission.
As a result, open protocols must depend on donation based grant funding from the people and organizations that rely on them. This model works but it is slow and uncertain, a grind where sustainability is never fully reached but rather constantly sought. As someone who has been incredibly active in the open source grant funding space, I do not think people truly appreciate how difficult it is to raise charitable money and deploy it efficiently.
Projects that can be monetized should be. Profitability is a super power. When a business can generate revenue, it taps into a self sustaining cycle. Profit fuels growth and development while providing projects independence and agency. This flywheel effect is why companies like Google, Amazon, and Apple have scaled to global dominance. The profit incentive aligns human effort with efficiency. Businesses must innovate, cut waste, and deliver value to survive.
Contrast this with non monetized projects. Without profit, they lean on external support, which can dry up or shift with donor priorities. A profit driven model, on the other hand, is inherently leaner and more adaptable. It is not charity but survival. When survival is tied to delivering what people want, scale follows naturally.
The real magic happens when profitable, sustainable businesses are built on top of open protocols and software. Consider the many startups building on open source software stacks, such as Start9, Mempool, and Primal, offering premium services on top of the open source software they build out and maintain. Think of companies like Block or Strike, which leverage bitcoin’s open protocol to offer their services on top. These businesses amplify the open software and protocols they build on, driving adoption and improvement at a pace donations alone could never match.
When you combine open software and protocols with profit driven business the result are lean, sustainable companies that grow faster and serve more people than either could alone. Bitcoin’s network, for instance, benefits from businesses that profit off its existence, while nostr will expand as developers monetize apps built on the protocol.
Capitalism scales best because competition results in efficiency. Donation funded protocols and software lay the groundwork, while market driven businesses build on top. The profit incentive acts as a filter, ensuring resources flow to what works, while open systems keep the playing field accessible, empowering users and builders. Together, they create a flywheel of innovation, growth, and global benefit.

2025-05-23 22:00:29Flash, an all-in-one Bitcoin payment platform, has announced the launch of Flash 2.0, the most intuitive and powerful Bitcoin payment solution to date.
With a completely redesigned interface, expanded e-commerce integrations, and a frictionless onboarding process, Flash 2.0 makes accepting Bitcoin easier than ever for businesses worldwide.
We did the unthinkable!
Website monetization used to be super complicated.
"Buy me a coffee" — But only if we both have a bank account.
WHAT IF WE DON'T?
Thanks to @paywflash and bitcoin, it's just 5 CLICKS – and no banks!
Start accepting donations on your website… pic.twitter.com/uwZUrvmEZ1
— Flash • The Bitcoin Payment Gateway (@paywflash) May 13, 2025
Accept Bitcoin in Three Minutes
Setting up Bitcoin payments has long been a challenge for merchants, requiring technical expertise, third-party processors, and lengthy verification procedures. Flash 2.0 eliminates these barriers, allowing any business to start accepting Bitcoin in just three minutes, with no technical set-up and full control over their funds.
The Bitcoin Payment Revolution
The world is witnessing a seismic shift in finance. Governments are backing Bitcoin funds, major companies are adding Bitcoin to their balance sheets, and political figures are embracing it as the future of money. Just as Stripe revolutionized internet payments, Flash is now doing the same for Bitcoin. Businesses that adapt today will gain a competitive edge in a rapidly evolving financial landscape.
With Bitcoin adoption accelerating, consumers are looking for places to spend it. Flash 2.0 ensures businesses of all sizes can seamlessly accept Bitcoin and position themselves at the forefront of this financial revolution.
All-in-One Monetization Platform
More than just a payment gateway, Flash 2.0 is a complete Bitcoin monetization suite, providing multiple ways for businesses to integrate Bitcoin into their operations. Merchants can accept payments online and in-store, content creators can monetize with donations and paywalls, and freelancers can send instant invoices via payment links.
For example, a jewelry designer selling products on WooCommerce can now integrate Flash for online payments, use Flash’s Point-of-Sale system at trade shows, enable Bitcoin donations for her digital artwork, and lock premium content behind Flash Paywalls. The possibilities are endless.
E-Commerce for Everyone
With built-in integrations for Shopify, WooCommerce, and soon Wix and OpenCart, Flash 2.0 enables Bitcoin payments on 95% of e-commerce stores worldwide. Businesses can now add Bitcoin as a payment option in just a few clicks—without needing developers or external payment processors.
And for those looking to start selling, Flash’s built-in e-commerce features allow users to create online stores, showcase products, and manage payments seamlessly.
No Middlemen, No Chargebacks, No Limits
Unlike traditional payment platforms, Flash does not hold or process funds. Businesses receive Bitcoin directly, instantly, and securely. There are no chargebacks, giving merchants full control over refunds and eliminating fraud. Flash also remains KYC-free, ensuring a seamless experience for businesses and customers alike.
A Completely Redesigned Experience
“The world is waking up to Bitcoin. Just like the internet revolutionized commerce, Bitcoin is reshaping finance. Businesses need solutions that are simple, efficient, and truly decentralized. Flash 2.0 is more than just a payment processor—it’s a gateway to the future of digital transactions, putting financial power back into the hands of businesses.”
— Pierre Corbin, CEO at Flash.
Flash 2.0 introduces a brand-new user interface, making it easier than ever to navigate, set up payments, and manage transactions. With an intuitive dashboard, streamlined checkout, and enhanced mobile compatibility, the platform is built for both new and experienced Bitcoin users.

2025-05-23 22:00:28Bitcoin 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.

2025-05-21 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.

2025-04-04 06:58:30Introduction
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.
1. Financial Protection: Reclaiming Sovereignty Through Bitcoin
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!

2025-05-23 22:00:26Starting 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.

Nemojte kupovati Bitkoin!
Ni danas, ni kasnije, nikada!
Posvećeno skepticima, neznalicama, arogantnima i nezainteresovanima.
NE TREBA vam Bitkoin.
Molim vas. Nemojte ga kupovati.
Lično me ne zanima "masovna adopcija".
Draža mi je selektivna adopcija.
Svinja ne zaslužuje bisere.
Na vama je da platite cenu neznanja.
Kao i cenu glupavosti.
Kada dođe vreme, sa zadovoljstvom ću vam platiti hiljadu satošija mesečno za vaše vreme i smejati se usput.
Najbitnija odluka koju ćete ikada doneti
NEMA važnije odluke za vašu finansijsku, ekonomsku i suverenu budućnost koju danas možete doneti nego da kupite Bitkoin.
A ako ne želite da izdvojite malo vremena da ga dalje proučite, JEDINA osoba koju treba da krivite kasnije ste vi sami.
Danas, Bitkoin se nalazi u svojoj ranoj, početnoj fazi. O ovome možete više pročitati ovde (hvala ObiWan Kenobit):
Hiperbitkoinizacija: pobednik uzima sve
Ovo JE prilika ne samo vašeg života, već verovatno i najveći mogući transfer bogatstva u istoriji, a najluđa stvar je što će se najveći deo toga odigrati u narednih nekoliko decenija.
Nalazimo se tek u prvih 12 godina ove promene, a već smo videlo kako je Bitkoin eksplodirao sa $0.008c (kada su za 10.000 BTC kupljene dve pice) na trenutnu cenu od oko $11.500.
Ovo je tek početak. Tek 0.001% svetskog bogatstva je denominirano u Bitkoinu.
Ako sada izdvojite samo trenutak da razumete novac, njegovu ulogu u društvu i kako će ekonomski darvinizam voditi ceo svet prema najrobusnijem, najčvršćem i najsigurnijem obliku očuvanja bogatstva, možete odlučiti da kupite neki deo pre nego što se ostatak sveta priključi.
Čitajući ovo, vi ste poput drevnog pojedinca koji je pronašao zlato, dok svi ostali koriste školjke. Razlika je u tome što živite u digitalnom dobu tokom kojeg će se ovaj novac pojaviti i sazreti za vreme vašeg života. Taj drevni pojedinac bi bio u pravu ali mrtav zato što je zlatu bilo potrebno nekoliko hiljada godina da uradi ono za šta će Bitkoinu biti potrebne decenije.
Zamislite. Se. Nad. Tim.
I naučite dalje o nastanku Bitkoina ovde:
I za ime ljubavi prema sopstvenoj budućnosti, preuzmite ovu kratku elektronsku knjigu i jebeno se edukujte!!
Preuzmite "Investiranje u Bitkoin"
I eto, dajem vam izvore.. jbt.. Svejedno...
Danas, imate izbor da kupite Bitkoin; najoskudniji novac u univerzumu, za siću!! Bukvalno možete kupiti hiljade satošija (najmanju jedinicu Bitkoina gde je 100.000.000 satošija = 1 BTC) za $1!!!
Danas ne postoji veća prilika, kao što sutradan neće postojati veće žaljenje kada više ne budete imali "izbor" da ga kupite.
Kada taj dan bude došao i kada budete to morali da prihvatite, setićete se ovih reči, ali avaj, biće prekasno, a vreme ne možete vratiti.
Više nije 2012
Tada ste imali izgovor. Sada je 2020...
Apsolutno NEMA razloga zašto neko sa malo radoznalosti i relativno funkcionalnim mozgom ne može da prouči šta je Bitkoin, zašto postoji, zašto je važan i zašto bi trebalo da u njega prebaci malo ličnog bogatstva.
Naročito ako ima prijatelja poput mene ili mnoštvo Bitkoinera negde tamo.
Ja više neću smarati ljude sa porukama "zašto treba kupiti Bitkoin".
Više nije 2012. godina.
Danas imamo toliko puno informacija od toliko mnogo dobrih ljudi na svim mogućim medijima, tako da NEMATE IZGOVORA da ga ignorišete ili kažete: "ali niko mi nije rekao".
Ukoliko nemate da izdvojite bar malo vremena od vašeg Netflix rasporeda da biste istražili šta je ova stvar i zašto je bitna za vašu ličnu ekonomsku budućnost, onda zaslužujete to što imate.
Deluje okrutno ali dobrodošao u život, mladi žutokljunče.
Sada... Ako ste izdvojili malo vremena ali ste i dalje nezainteresovani ili dovoljno glupi da ga odbacite, onda zaista zaslužujete to što dolazi i ostatak ovog članka je definitivno za vas.
Ne želim da uopšte kupite Bitkoin!
Ok Aleks, ali šta ćemo sa "masovnom adopcijom"???
Pažljivo me slušajte:
Zabole me kurac da li će masovna adopcija doći za 10, 20, 50 ili 100 godina!
Ja sam skroz za selektivnu adopciju i potpuno za dugačku igru. Tako da sam spreman da čekam.
Kao u SVIM prirodnim, evolutivno funkcionalnim sistemima, oni koji seju i pomažu u izgradnji temelja bi trebalo da budu i nesrazmerno nagrađeni.
Ovo je 100% fer i predivno nejednako (neki od vas koji me znate ste upoznati sa mojim stavom o nejednakosti kao najprezrenijem od svih ljudskih ideala. Radi se o odvratnom idealu koji nagrađuje najgore među nama).
Tako da za skeptike i "neverne Tome" imam jednostavnu poruku:
Nadam se da nećete uopšte kupiti Bitkoin. Ni danas ni bilo kada. Nadam se da će jedini put kada budete stupili u dodir sa Bitkoinom to biti jedini način da za nešto budete isplaćeni; npr. kada budete morali da ga zaradite.
Jedva čekam dan kada će mojih nekoliko hiljada satošija moći da kupi tri, četiri ili pet meseci vašeg vremena.
A u međuvremenu...
Molim vas, držite se vašeg fiat novca. Molim vas, držite se vaših šitkoina.
Ne želim nikoga od vas "blokčejnera", šitkoinera, fiat nokoinera i vas svih ostalih klovnova koji mislite da znate bolje.
Ovaj rolerkoster je specijalan, tako da zašto bih želeo da ga delim sa vama glupanderima? Zašto bih bacao bisere pred svinje?
Ja verujem u principe isključivosti.
Ovo nije "kumbaya" ili "svi smo jedno". Jebite se.
Sa razlogom smo drugačiji.
Napraviću sam svoj krevet i ležati u njemu. Vi napravite svoje.
Kada bude došlo vreme, ja ću vam za vaše vreme plaćati satošijima zato što onda nećete imati izbora.
Tada ja pobeđujem, a vi gubite.
Kako sejete, tako žanjete
Razlika između mene i vas je ta što ja kupujem Bitkoin sada zato što tako želim. Vi ćete morati da radite za Bitkoin sutra zato što tako morate.
To je cena neznanja. To je cena arogancije.
To je cena gluposti koju ćete platiti i, koliko god ovo zvuči okrutno, istina je da zaslužujete svaki delić toga.
Svi ležimo u krevetu koji sami pravimo, a vi svoj krevet pravite sada.
Neće vam samouvereni Bitkoiner reći: "lepo sam vam rekao". Nova ekonomska realnost će vam to reći umesto njega.
"Lepo sam vam rekao" će vas udariti poput tone cigle kada shvatite razliku između vas i onih koji su bili razboriti, koji su marljivo štedeli, koji su uložili vreme i trud da otkriju šta je zapravo Bitkoin dok su ih svi nazivali ludacima.
Neće biti sažaljenja.
Nema više bacanja bisera pred svinje
Oni koji imaju priliku da kupe nešto Bitkoina sada, a odluče da to ne urade zahvaljujući neznanju, aroganciji ili gluposti, zaslužuju da plate sa kamatom.
Zaslužuju da trguju svoje sutrašnje dragoceno vreme i energiju za ono što su mogli da nabave danas i to bukvalno "za kikiriki".
Ovde nema greške: nismo jednaki. Mi smo veoma, veoma različiti ljudi.
Ja sam uložio vreme, trud i energiju sada, ne samo zbog sebe samog, već i da bih posadio seme i pomogao mreži.
Uradio sam svoj deo.
Vi ćete doći kasnije i pomoći mi da žanjem nagrade svog truda. Postojaćete da biste mi pomogli da uživam u plodovima.
To će biti vaša uloga.
Izabrao sam da rizikujem i steknem deo onoga zbog čega su me svi nazivali ludim zato što sam učio, verovao i shvatio danas, sa nadom da se izgradi bolja, poštenija i pravičnija budućnost za sve.
Radeći to, neki od nas će postati džinovi i nesrazmerno bogati. I vi imate tu šansu ali je mnogi od vas neće iskoristiti.
I ja sam skroz ok sa tim. Više neću bacati bisere pred svinje.
Ovaj članak može zvučati neprijatno ali više me zabole kurac. Sada je na vama da sami istražujete.
Ovo se događa bez obzira sviđalo vam se to ili ne. Ja i hiljade drugih Bitkoinera smo pisali eseje i eseje o ovome.
Neka imena sa kvalitetnim materijalom kojih se mogu setiti iz glave su:
- Naravno ja
- Gigi
- Robert Breedlove
- Saifedean Ammous
Ako ste radoznali možete ih pratiti. A ovo je sjajno mesto gde možete preuzeti nekoliko odličnih radova:
I za kraj, ako si Bitkoiner koji ovo čita, nikada nećeš znati da li sam zloban ili samo igram 4D šah.
Iskreno, nije ni bitno.
Ovo se dešava. Bitkoin osvaja svet. Ekonomski darvinizam je činjenica.
Sakupljajte vaše satošije, ponudite maslinovu grančicu, obratite pažnju na njihovu radoznalost ili iskru u njihovom oku kao znak da nastavite. Ukoliko toga nema ili naiđete na odbijanje, ostavite ih da se igraju kao svinje u govnima sa njihovim fiatom, deonicama ili šitkoinima.
Biće nam potrebni čistači za naše citadele.

2025-05-23 22:00:25This 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

2025-05-23 18:23:28I've sporadically been trying to spend some time familiarizing myself with Nostr marketplace listings and the clients that support them. I have been pleased with what I have encountered. The clients are simple to use, and people have been receptive to transacting with me. I've sold items to both people whom I consider to be close contacts, as well as to people that I barely know.
My first attempt was close to 2 years ago, when I listed one pound bags of coffee for sale. If I remember correctly, there was only one marketplace client then, and it only had support for extension signing. At the time, my old laptop had just died so I couldn't really interact with my listings through that client. (I have never had much luck with extensions on mobile browsers, so I have never attempted to use one for Nostr.) Instead, I used Amethyst to list my product and exchange messages with potential buyers. The Amethyst approach to handling different Nostr events is brilliant to me. You can do some part of each thing but not all. I view it as great introduction to what Nostr is capable of doing and a gateway to discovering other clients. Marketplace listings on Amethyst are handled in that fashion. You can list products for sale. You can browse and inquire about products listed by your contacts or by a more "global" view, which in the case of Nostr, would be products listed by anyone who publishes their listings to any of the relays that I connect with to read. There is no delete option, should a product sell out, and there is no direct purchase option. All sales need to be negotiated through direct messages. Though it has limited functionality, the system works great for items that will be listed for repeated sale, such as my coffee. If one were to list a one-off item and sell it, the flow to delete the listing would be easy enough. Copy the event ID, visit delete.nostr.com , and remove the product. Should there be a price change, it would be necessary to visit a full marketplace client to edit the listing, though one could easily delete and start over as well. Anyway, much to my surprise I sold more coffee than I had anticipated through that listing. People were eager to try out the feature and support a small business. This was an awesome experience and I see no reason to avoid buying or selling products on Nostr, even if the only client available to you is Amethyst. (Which I think might be the only mobile app with marketplace support.) It is completely manageable.
Later, I tried to list a pair of nearly new shoes. Those did not sell. I have a sneaking suspicion that there were very few people that wore size USw6 shoes using Nostr at the time. Even though no one wanted my shoes, I still ended up having some interesting conversations about different styles of running shoes, boots, and other footwear talk. I can't call the listing a total bust, even though I ended up deleting the listing and donating those shoes to the YWCA. After some number of months watching and reading about development in the Nostr marketplace space, I decided to try again.
This second approach, I started with niche rubber duckies that, for reasons unbeknownst to most, I just happen to have an abundance of. It occurred to me that day that I would most likely be creating most of my listings via mobile app since that is also my main method of taking pictures these days. I could sync or send them, but realistically it's just adding extra steps for me. I listed my ducks with Amethyst (all of which are currently still available, surprise, surprise.). I immediately went to check how the listing renders in the marketplace clients. There are 2 where I can view it, and the listing looks nice, clean, organized in both places. That alone is reason enough to get excited about selling on Nostr. Gone are the days of "this item is cross-posted to blah, blah, blah" lest risk being kicked out of the seller groups on silo'd platforms.
Knowing I can't take it personally that literally no one else on Nostr has an affinity for obscure rubber ducks (that they are willing to admit), I leave my duckies listed and move on. My next listing is for artisan bracelets. Ones that I love to make. I made my mobile listing, checked it across clients and this time I noticed that shopstr.store is collecting my listings into a personal seller profile, like a little shop. I spent some time setting up the description and banner, and now it looks really nice. This is great, since the current site acts as an open and categorized market for all sellers. Maybe someone will see the bracelets while browsing the clothing category and stumble upon the rubber ducky of their dreams in the process. That hasn't happened yet, but I was pretty jazzed to sell a few bracelets right away. Most of the sale and exchange happened via DM, for which I switched to Flotilla because it just handles messaging solidly for me. I made some bracelets, waited a few weeks, then visited Shopstr again to adjust the price. That worked out super well. I noticed that a seller can also list in their preferred currency, which is very cool. Meanwhile, back to my social feed, I can see my listing posted again since there was an edit. While not always the best thing to happen with edits, it is great that it happens with marketplace listings. It removes all the steps of announcing a price reduction, which would be handy for any serious seller. I am very happy with the bracelet experience, and I will keep that listing active and reasonably up to date for as long as any interest arises. Since this has all gone so well, I've opted to continue listing saleable items to Nostr first for a few days to a few weeks prior to marketing them anywhere else.
Looking at my listings on cypher.space, I can see that this client is tailored more towards people who are very passionate about a particular set of things. I might not fall into this category but my listings still look very nice displayed with my writing, transposed poetry, and recipes. I could see this being a great space for truly devotional hobbyists or sellers who are both deeply knowledgeable about their craft and also actively selling. My experience with all 3 of these marketplace-integrated clients had been positive and I would say that if you are considering selling on Nostr, it is worth the effort.
As some sidenotes:
-
I am aware that Shopstr has been built to be self-hosted and anyone interested in selling for the long term should at least consider doing so. This will help reduce the chances of Nostr marketplaces centralizing into just another seller-silo.
-
Plebeian Market is out there, too. From the best I could tell, even though this is a Nostr client, those listings are a different kind than listings made from the other clients referenced here. I like the layout and responsiveness of the site but I opted not to try it out for now. Cross-posting has been the bane of online selling for me for quite some time. If they should migrate to an interoperable listing type (which I think I read may happen in the future), I will happily take that for a spin, too.
-
My only purchase over Nostr marketplaces so far was some vinyls, right around the time I had listed my coffee. It went well, the seller was great to work with, everything arrived in good shape. I have made some other purchases through Nostr contacts, but those were conversations that lead to non-Nostr seller sites. I check the marketplace often, though, for things I may want/need. The listings are changing and expanding rapidly, and I foresee more purchases becoming a part of my regular Nostr experience soon enough.
-
I thought about including screenshots for this, but I would much rather you go check these clients out for yourself.

1. Wallet of Satoshi (WoS)
Custodial — you don’t touch Lightning directly
Sending sats:
- You open WoS, paste a Lightning invoice, hit send.
- WoS handles the payment entirely within their system.
- If recipient uses WoS: internal balance update.
- If external: routed via their node.
- You never open channels, construct routes, or sign anything.
Withdrawing to L1:
- You paste a Bitcoin address.
- WoS sends a regular on-chain transaction from their custodial wallet.
- You pay a fee. It’s like a bank withdrawal.
You don’t interact with Lightning directly. Think of it as a trusted 3rd party Lightning “bank”.
2. Phoenix Wallet
Non-custodial — you own keys, Phoenix handles channels
Sending sats:
- You scan a Lightning invoice and hit send.
- Phoenix uses its backend node (ACINQ) to route the payment.
- If needed, it opens a real 2-of-2 multisig channel on-chain automatically.
- You own your keys (12-word seed), Phoenix abstracts the technical parts.
Withdrawing to L1:
- You enter your Bitcoin address.
- Phoenix closes your Lightning channel (cooperatively, if possible).
- Your sats are sent as a real Bitcoin transaction to your address.
You’re using Lightning “for real,” with real Bitcoin channels — but Phoenix smooths out the UX.
3. Your Own Lightning Node
Self-hosted — you control everything
Sending sats:
- You manage your channels manually (or via automation).
- Your node:
- Reads the invoice
- Builds a route using HTLCs
- Sends the payment using conditional logic (preimages, time locks).
- If routing fails: retry or adjust liquidity.
Withdrawing to L1:
- You select and close a channel.
- A channel closing transaction is broadcast:
- Cooperative = fast and cheap
- Force-close = slower, more expensive, and time-locked
- Funds land in your on-chain wallet.
You have full sovereignty — but also full responsibility (liquidity, fees, backups, monitoring).
Core Tech Behind It: HTLCs, Multisig — and No Sidechain
- Lightning channels = 2-of-2 multisig Bitcoin addresses
- Payments = routed via HTLCs (Hashed Time-Locked Contracts)
- HTLCs are off-chain, but enforceable on-chain if needed
- Important:
- The Lightning Network is not a sidechain.
- It doesn't use its own token, consensus, or separate blockchain.
- Every Lightning channel is secured by real Bitcoin on L1.
Lightning = fast, private, off-chain Bitcoin — secured by Bitcoin itself.
Summary Table
| Wallet | Custody | Channel Handling | L1 Withdrawal | HTLC Visibility | User Effort | |--------------------|--------------|------------------------|---------------------|------------------|--------------| | Wallet of Satoshi | Custodial | None | Internal to external| Hidden | Easiest | | Phoenix Wallet | Non-custodial| Auto-managed real LN | Channel close | Abstracted | Low effort | | Own Node | You | Manual | Manual channel close| Full control | High effort |
Bonus: Withdrawing from LN to On-Chain
- WoS: sends sats from their wallet — like PayPal.
- Phoenix: closes a real channel and sends your UTXO on-chain.
- Own node: closes your multisig contract and broadcasts your pre-signed tx.
Bitcoin + Lightning = Sovereign money + Instant payments.
Choose the setup that fits your needs — and remember, you can always level up later.P.S. What happens in Lightning... usually stays in Lightning.

2025-05-23 17:01:37The recent anomalies in the financial market and the frequent occurrence of world trade wars and hot wars have caused the world's political and economic landscape to fluctuate violently. It always feels like the financial crisis is getting closer and closer.
This is a systematic analysis of the possibility of the current global financial crisis by Manus based on Ray Dalio's latest views, US and Japanese economic and financial data, Buffett's investment behavior, and historical financial crises.
Research shows that the current financial system has many preconditions for a crisis, especially debt levels, market valuations, and investor behavior, which show obvious crisis signals. The probability of a financial crisis in the short term (within 6-12 months) is 30%-40%,
in the medium term (within 1-2 years) is 50%-60%,
in the long term (within 2-3 years) is 60%-70%.
Japan's role as the world's largest holder of overseas assets and the largest creditor of the United States is particularly critical. The sharp appreciation of the yen may be a signal of the return of global safe-haven funds, which will become an important precursor to the outbreak of a financial crisis.
Potential conditions for triggering a financial crisis Conditions that have been met 1. High debt levels: The debt-to-GDP ratio of the United States and Japan has reached a record high. 2. Market overvaluation: The ratio of stock market to GDP hits a record high 3. Abnormal investor behavior: Buffett's cash holdings hit a record high, with net selling for 10 consecutive quarters 4. Monetary policy shift: Japan ends negative interest rates, and the Fed ends the rate hike cycle 5. Market concentration is too high: a few technology stocks dominate market performance
Potential trigger points 1. The Bank of Japan further tightens monetary policy, leading to a sharp appreciation of the yen and the return of overseas funds 2. The US debt crisis worsens, and the proportion of interest expenses continues to rise to unsustainable levels 3. The bursting of the technology bubble leads to a collapse in market confidence 4. The trade war further escalates, disrupting global supply chains and economic growth 5. Japan, as the largest creditor of the United States, reduces its holdings of US debt, causing US debt yields to soar
Analysis of the similarities and differences between the current economic environment and the historical financial crisis Debt level comparison Current debt situation • US government debt to GDP ratio: 124.0% (December 2024) • Japanese government debt to GDP ratio: 216.2% (December 2024), historical high 225.8% (March 2021) • US total debt: 36.21 trillion US dollars (May 2025) • Japanese debt/GDP ratio: more than 250%-263% (Japanese Prime Minister’s statement)
Before the 2008 financial crisis • US government debt to GDP ratio: about 64% (2007) • Japanese government debt to GDP ratio: about 175% (2007)
Before the Internet bubble in 2000 • US government debt to GDP ratio: about 55% (1999) • Japanese government debt to GDP ratio: about 130% (1999)
Key differences • The current US debt-to-GDP ratio is nearly twice that before the 2008 crisis • The current Japanese debt-to-GDP ratio is more than 1.2 times that before the 2008 crisis • Global debt levels are generally higher than historical pre-crisis levels • US interest payments are expected to devour 30% of fiscal revenue (Moody's warning)
Monetary policy and interest rate environment
Current situation • US 10-year Treasury yield: about 4.6% (May 2025) • Bank of Japan policy: end negative interest rates and start a rate hike cycle • Bank of Japan's holdings of government bonds: 52%, plans to reduce purchases to 3 trillion yen per month by January-March 2026 • Fed policy: end the rate hike cycle and prepare to cut interest rates
Before the 2008 financial crisis • US 10-year Treasury yield: about 4.5%-5% (2007) • Fed policy: continuous rate hikes from 2004 to 2006, and rate cuts began in 2007 • Bank of Japan policy: maintain ultra-low interest rates
Key differences • Current US interest rates are similar to those before the 2008 crisis, but debt levels are much higher than then • Japan is in the early stages of ending its loose monetary policy, unlike before historical crises • The size of global central bank balance sheets is far greater than at any time in history
Market valuations and investor behavior Current situation • The ratio of stock market value to the size of the US economy: a record high • Buffett's cash holdings: $347 billion (28% of assets), a record high • Market concentration: US stock growth mainly relies on a few technology giants • Investor sentiment: Technology stocks are enthusiastic, but institutional investors are beginning to be cautious
Before the 2008 financial crisis • Buffett's cash holdings: 25% of assets (2005) • Market concentration: Financial and real estate-related stocks performed strongly • Investor sentiment: The real estate market was overheated and subprime products were widely popular
Before the 2000 Internet bubble • Buffett's cash holdings: increased from 1% to 13% (1998) • Market concentration: Internet stocks were extremely highly valued • Investor sentiment: Tech stocks are in a frenzy
Key differences • Buffett's current cash holdings exceed any pre-crisis level in history • Market valuation indicators have reached a record high, exceeding the levels before the 2000 bubble and the 2008 crisis • The current market concentration is higher than any period in history, and a few technology stocks dominate market performance
Safe-haven fund flows and international relations Current situation • The status of the yen: As a safe-haven currency, the appreciation of the yen may indicate a rise in global risk aversion • Trade relations: The United States has imposed tariffs on Japan, which is expected to reduce Japan's GDP growth by 0.3 percentage points in fiscal 2025 • International debt: Japan is one of the largest creditors of the United States
Before historical crises • Before the 2008 crisis: International capital flows to US real estate and financial products • Before the 2000 bubble: International capital flows to US technology stocks
Key differences • Current trade frictions have intensified and the trend of globalization has weakened • Japan's role as the world's largest holder of overseas assets has become more prominent • International debt dependence is higher than any period in history

2025-05-11 17:28:34This article explores potential vulnerabilities in bitcoin that quantum computers might exploit in the future.
But to be clear: today’s quantum computers are still in early stages, many questions are unresolved, and they are not expected to pose a serious threat any time soon.
1. Why Quantum Computing Threatens Bitcoin
Bitcoin’s current cryptographic security relies on ECDSA (Elliptic Curve Digital Signature Algorithm). While this is secure against classical computers, a sufficiently powerful quantum computer could break it using Shor’s algorithm, which would allow attackers to derive private keys from exposed public keys. This poses a serious threat to user funds and the overall trust in the Bitcoin network.
Even though SHA-256, the hash function used for mining and address creation, is more quantum-resistant, it too would be weakened (though not broken) by quantum algorithms.
2. The Core Problem
Bitcoin’s vulnerability to quantum computing stems from how it handles public keys and signatures.
🔓 Public Key Exposure
Most Bitcoin addresses today (e.g., P2PKH or P2WPKH) are based on a hash of the public key, which keeps the actual public key hidden — until the user spends from that address.
Once a transaction is made, the public key is published on the blockchain, making it permanently visible and linked to the address.
🧠 Why This Matters
If a sufficiently powerful quantum computer becomes available in the future, it could apply Shor’s algorithm to derive the private key from a public key.
This creates a long-term risk:
- Any Bitcoin tied to an address with an exposed public key — even from years ago — could be stolen.
- The threat persists after a transaction, not just while it’s being confirmed.
- The longer those funds sit untouched, the more exposed they become to future quantum threats.
⚠️ Systemic Implication
This isn’t just a theoretical risk — it’s a potential threat to long-term trust in Bitcoin’s security model.
If quantum computers reach the necessary scale, they could: - Undermine confidence in the finality of old transactions - Force large-scale migrations of funds - Trigger panic or loss of trust in the ecosystem
Bitcoin’s current design protects against today’s threats — but revealed public keys create a quantum attack surface that grows with time.
3. Why It’s Hard to Fix
Transitioning Bitcoin to post-quantum cryptography is a complex challenge:
- Consensus required: Changes to signature schemes or address formats require wide agreement across the Bitcoin ecosystem.
- Signature size: Post-quantum signature algorithms could be significantly larger, which affects blockchain size, fees, and performance.
- Wallet migration: Updating wallets and moving funds to new address types must be done securely and at massive scale.
- User experience: Any major cryptographic upgrade must remain simple enough for users to avoid security risks.
4. The Path Forward
The cryptographers worldwide are already working on solutions:
- Post-Quantum Cryptographic Algorithms are being standardized by NIST, including CRYSTALS-Dilithium, Kyber, FALCON, and SPHINCS+.
- Prototypes and experiments are ongoing research networks.
- Hybrid signature schemes are being explored to allow backward compatibility.
Governments and institutions like NIST, ENISA, and ISO are laying the foundation for cryptographic migration across industries — and Bitcoin will benefit from this ecosystem.

blossom的网址 变成了sha256 的id值,理论上 更换服务器或者重传以后 替换图片地址方便。
不过这部分我并没有做兼容接口。如果做成兼容的,应该用 相对地址,然后 后台用proxyimg.xxx.com去做选择。
访问方便些
新的服务器是:https://nosto.re/ 希望他能稳定的被访问不会嘎。
代码其实更简单了,https://github.com/nostrbook/nostrbook/blob/main/src/lib/blossomUpload.ts nosto.re 没有checkupload功能。所以我这里代码也没有加这部分,如果换别的服务器可能需要加检查功能。是不是为了防止图片重复上传?
最后 加一张好看的图片吧。证明此功能好用:

2025-05-23 15:36:32Use this guide if you want to keep your NixOS on the stable branch, but enable unstable application packages. It took me a while to figure out how to do this, so I wanted to share because it ended up being far easier than most of the vague explanations online made it seem.
I put a sample configuration.nix file at the very bottom to help it make more sense for new users. Remember to keep a backup of your config file, just in case!
If there are any errors please let me know. I am currently running NixOS 24.11.
Steps listed in this guide: 1. Add the unstable channel to NixOS as a secondary channel. 2. Edit the configuration.nix to enable unstable applications. 3. Add "unstable." in front of the application names in the config file (example: unstable.program). This enables the install of unstable versions during the build. 4. Rebuild.
Step 1:
- Open the console. (If you want to see which channels you currently have, type: sudo nix-channel --list)
- Add the unstable channel, type: sudo nix-channel --add https://channels.nixos.org/nixpkgs-unstable unstable
- To update the channels (bring in the possible apps), type: sudo nix-channel --update
More info here: https://nixos.wiki/wiki/Nix_channels
Step 2:
Edit your configuration.nix and add the following around your current config:
``` { config, pkgs, lib, ... }:
let unstable = import
{ config = { allowUnfree = true; }; }; in { #insert normal configuration text here } #remember to close the bracket!
```
At this point it would be good to save your config and try a rebuild to make sure there are no errors. If you have errors, make sure your brackets are in the right places and/or not missing. This step will make for less troubleshooting later on if something happens to be in the wrong spot!
Step 3:
Add "unstable." to the start of each application you want to use the unstable version. (Example: unstable.brave)
Step 4:
Rebuild your config, type: sudo nixos-rebuild switch
Example configuration.nix file:
```
Config file for NixOS
{ config, pkgs, lib, ... }:
Enable unstable apps from Nix repository.
let unstable = import
{ config = { allowUnfree = true; }; }; in { #Put your normal config entries here in between the tags. Below is what your applications list needs to look like.
environment.systemPackages = with pkgs; [ appimage-run blender unstable.brave #Just add unstable. before the application name to enable the unstable version. chirp discord ];
} # Don't forget to close bracket at the end of the config file!
``` That should be all. Hope it helps.

2025-05-23 15:26:17While I’m going to stand by what I said in my previous piece, minimise capital gains payments, don’t fund the government, get a loan against your bitcoin, but the wheels in my left curve brain have continued to turn, well that, and a few more of my 40PW insights. I mentioned about paying attention to the risks involved in terms of borrowing against your bitcoin, and hopefully ending up paying less in bitcoin at the end of the loan, even if you ultimately sold bitcoin to pay off the loan. However, the idea of losing control of the bitcoin I have spent a good deal of time and effort accumulating being out of my control has led me to reconsider. I also realised I didn’t fully flesh out some other topics that I think are relevant, not least time preference, specifically in relation to what you’re buying. The idea of realising a lump some of capital to live your dreams, buy a house or a cool car may be important, but it may be worth taking a step back and looking at what you’re purchasing. Are you only purchasing those things because you had been able to get this new money “tax free”? If that is the case, and the fiat is burning a hold in your pocket, maybe you’ve just found yourself with the same fiat brained mentality you have been working so hard to escape from while you have sacrificed and saved to stack sats.
While it may no longer be necessary to ask yourself whether a particular product or service is worth selling your bitcoin for because you’ve taken out a loan, it may still be worth asking yourself whether a particular loan fuelled purchase is worth forfeiting control of your keys for? Unlike the foolish 18 year-old, released into a world with their newly preapproved credit card, you need to take a moment and ask yourself:
Is the risk worth it?
Is the purchase worth it?
But also take a moment to consider a number of other things, are there fiat options?
Where in the cycle might you be?
Or if I’m thinking carefully about this, will whatever I’m buying hold its value (experiences may be more difficult to run the numbers on)?
The reason for asking these things, is that if you still have a foot in the fiat world, dealing with a fiat bank account, fiat institutions may still be very willing to provide you with a loan at a lower rate than a bitcoin backed loan. Particularly if you’re planning on using that money to buy a house; if you can qualify for a mortgage, get a mortgage, but if you need cash for a deposit, maybe that is where the bitcoin backed loan may come in. Then, it may be worth thinking about where are you in the bitcoin cycle? No one can answer this, but with the historic data we have, it appears logical that after some type of run up, prices may retrace (Dan Held’s supercycle withstanding).
Matteo Pellegrini with Daniel Prince provided a new perspective on this for me. Rather the riding the bull market gains all the way through to the bear market bottom, what happens if I chose to buy an asset that didn’t lose quite as much fiat value as bitcoin, for example, a Swiss Watch, or a tasteful, more mature sports car? If that was the purchase of choice, they suggested that you could enjoy the car, “the experience” for a year or two, then realise the four door estate was likely always the better option, sell it and be able to buy back as many, if not slightly more bitcoin that you originally sold (not financial, classic car or price prediction advice, I’m not accredited to advise pretty much anything). Having said that, it is a scenario I think worth thinking about when the bitcoin denominated dream car begins to make financial sense.
Then, as we begin to look forward to the near inevitable bear market (they are good for both stacking and grinding), if we’ve decided to take out a loan rather than sell, we then may ultimately need to increase our collateral to maintain loan to value requirements, as well as sell more bitcoin to cover repayments (if that’s the route we’re taking). This then moves us back into the domain of saying, well in actual fact we should just sell our bitcoin when we can get most dollar for it (or the coolest car), with a little extra to cover future taxes, it is probably better to sell near a top than a bottom. The balance between these two rather extreme positions could be to take out a fiat loan to buy the item and maybe sell sufficient bitcoin so you’re able to cover the loan for a period of time (less taxable events to keep track of and also deals with future uncertainty of bitcoin price). In this case, if the loan timeframe is longer than the amount of loan your sale can cover, by the time you need to sell anymore, the price should have recovered from a cycle bottom.
In this scenario, apart from the smaller portion of bitcoin you have had to sell, the majority of your stack can remain in cold storage, the loan you took out will be unsecured (particularly against your bitcoin), but even if it isn’t, the value of what you purchase maintains its value, you can in theory exit the loan at any point by selling the luxury item. Then within this scenario, if you had sold near a top, realised the car gave you a bad back or made you realise you staying humble is more important, sold it, paid off the loan, there may even be a chance you could buy back more bitcoin with the money you had left over from selling your bitcoin to fund the loan.
I have no idea of this could actually work, but to be honest, I’m looking forward to trying it out in the next 6-12 months, although I may keep my daily driver outside of my bitcoin strategy (kids still need a taxi service). Having said that, I think there are some important points to consider in addition to not paying capital gains tax (legally), as well as the opportunities of bitcoin loans. They are still very young products and to quote every trad-fi news outlet, “bitcoin is still a volatile asset”, these thought experiments are still worth working through. To push back on the Uber fiat journalist, Katie Martin, “Bitcoin has no obvious use case”, it does, it can be a store of value to hold or sell, it can be liquid and flexible collateral, but also an asset that moves independently of other assets to balance against fiat liabilities. The idea of being able to release some capital, enjoy the benefits of the capital for a period, before returning that capital to store value feels like a compelling one.
The important thing to remember is that there are a variety of options, whether selling for cash, taking out a bitcoin backed loan, taking out a fiat loan or some combination of each. Saying that, what I would think remains an important question to ask irrespective of the option you go for:
Is what I’m planning on buying, worth selling bitcoin for?
If it cannot pass this first question, maybe it isn’t worth purchasing to start with.

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.

2025-05-08 15:05:45Good morning, readers!
This week, we bring reports from Bangladesh, where the interim government instructed the central bank to halt the printing of old banknotes featuring Sheikh Mujibur Rahman, the founding president of Bangladesh. This has induced a currency shortage, as new notes have yet to be issued to replace the discontinued ones. As a result, Bangladeshis find themselves holding worthless currency, facing increased costs, and feeling frustrated over such poor currency management. Meanwhile, in Indonesia, citizens are fleeing to gold as the local rupiah currency crashes to record lows amid increasing financial controls from the government.
In open-source news, LNbits, a Bitcoin and Lightning wallet management software, emerged from beta with its v1.0.0 release. LNbits works like a control panel on top of a Bitcoin wallet, letting users divide funds into separate accounts and use different features and functionalities. It is a handy tool for educators, civil society organizations, and communities who want to use Bitcoin for real-world transactions without needing advanced technical skills. We also spotlight a new tool called following .space that allows users to curate and share premade follow packs for nostr. The result is a more straightforward onboarding process for new users interested in censorship-resistant social media and the ability to curate feeds to better suit their interests.
We end with an interview with HRF Chief Strategy Officer Alex Gladstein, who explores his thinking behind the relationship between Bitcoin and human rights as we enter an age of increased corporate and nation-state adoption. He highlights the paradox where Bitcoin, a tool for individual financial freedom, is being adopted by institutions around the world, many of which regularly seek greater control over financial activity. We also include a new report from Bitcoin developer and past HRF grantee, b10c, who documents the current state of Bitcoin mining centralization and the threat it poses to decentralization and censorship resistance.
Now, let’s jump right in!

GLOBAL NEWS
Bangladesh | Currency Shortage as Central Bank Halts Printing of Banknotes
A state-induced cash crunch is paralyzing Bangladesh after the interim government, led by Muhammad Yunus, ordered the central bank to discontinue old banknotes featuring Sheikh Mujibur Rahman, the founding president of Bangladesh. New cash is expected to be printed in phases beginning in May. But Bangladeshis report they are currently stuck with old and unusable currency, as the national mint has yet to issue replacement currency and lacks the capacity to print more than three notes at a time. Meanwhile, public ATMs continue to dispense old and worn-out banknotes, with merchants reluctantly accepting them and banks refusing to exchange them. Through all this, the central bank of Bangladesh sits on nearly 15,000 crore taka ($1.28 billion) worth of old notes in vaults, but the interim government has refused to release them, deepening public frustration.
Nigeria | Regulates Bitcoin as a Security
Nigerian lawmakers are moving to regulate digital assets as securities by passing the Investment and Securities Act (ISA) 2025. Rather than embrace it as a tool for financial freedom, the law places Bitcoin under the purview of the Nigerian Securities and Exchange Commission (SEC). Companies must now register with the Nigerian SEC, implement more strict data-collection processes (to harvest personal information), and navigate a legal framework not designed for a borderless and permissionless technology like Bitcoin. The law further grants the SEC access to data from telecom and Internet providers to investigate “illegal market activity” — a provision that could easily be abused to surveil or intimidate Bitcoin users and developers. Nigeria routinely uses regulations to stifle the presence of open-source money, raising compliance hurdles, imposing taxes, and punishing digital asset companies. It’s not unreasonable to suspect this new classification could provide the state with a means to suppress the free adoption and innovation of Bitcoin.
Indonesia | Gold Rush Amid Economic Uncertainty
As the rupiah currency falls to record lows, Indonesians are flocking to gold in a rush to protect their savings. But gold isn’t the only safe haven. With 74% of Indonesia’s population unbanked or underbanked, digital tools like Bitcoin offer a more accessible alternative, especially when nearly 70% of Indonesians have Internet access. The Indonesian government is also tightening capital controls. A new policy forces exporters to keep all foreign currency earnings inside the country for a full year to trap dollars in the financial system. HRF grantee Bitcoin Indonesia is responding by helping people in the region (especially in nearby states like Burma) build financial resilience through meetups, workshops, and training focused on Bitcoin custody, privacy, and adoption. In an area where financial services remain out of reach for millions, learning how to save and transact permissionlessly is paramount.
Kenya | Introduces Legal Framework for Virtual Asset Service Providers (VASPs)
Kenya’s government introduced a comprehensive legal framework to regulate Virtual Asset Service Providers (VASPs) through its newly proposed 2025 VASP Bill. The legislation outlines strict licensing requirements for digital asset exchanges, wallet providers, brokers, and other digital asset firms. It functionally bars individuals from operating independently (think: open-source freedom tech builders) by mandating local incorporation, compliance with cybersecurity standards, and approval from financial regulators. This appears to be an attempt to formalize and better control the rapidly growing digital asset space. It could stifle grassroots innovation and limit access to financial tools that have become vital for activists and citizens seeking privacy and autonomy as economic policies and high inflation drive unrest.
El Salvador | Attorney General’s Office Preparing Arrest Warrants for Independent Journalists
El Faro, one of El Salvador’s most prominent investigative news outlets, shared reliable information that the Salvadoran Attorney General’s Office is preparing arrest warrants against three of its journalists. The warning came from El Faro director Carlos Dada, who suggests that the charges may include “apology for crimes” and “illicit association.” The alleged charges allegedly stem from El Faro’s latest reporting: a three-part video interview with former leaders of the 18th Street Revolucionarios gang that sheds light on Bukele’s “years-long relationship” with Salvadoran gangs. El Faro editor-in-chief Óscar Martínez said that any arrests or home raids following this news would be “for having done journalism.” With El Salvador’s shrinking civic space, this potential action against independent media would further restrict Salvadorans’ ability to access independent information and hold officials accountable.
BITCOIN AND FREEDOM TECH NEWS
LNbits | Emerges from Beta with v1.0.0 Release
LNbits, an open-source software tool that lets people create and manage Bitcoin Lightning wallets securely for themselves and for others, officially launched version 1.0.0, marking its transition out of beta and into a more stable release for public use. It works like a control panel sitting on top of a Bitcoin wallet, letting users divide funds into separate accounts and use different features and functionalities. LNbits is especially useful for educators, small businesses, and community organizers who want to use and manage Bitcoin for payments and savings. HRF is pleased to see this Bitcoin Development Fund (BDF) grantee strengthen the tools available to activists to achieve financial freedom in the face of censorship, surveillance, or inflation.
SeedSigner | Self-Custody Tool for Chinese Bitcoiners Facing Local Corruption
Chinese Bitcoin users are turning to SeedSigner, an open-source and fully customizable Bitcoin hardware wallet, as a more private way to protect their savings from law enforcement corruption. While many assume the primary threat to Bitcoin in China comes from top-down management and enforcement from the Chinese Communist Party (CCP), new reports suggest greater concern over the police, who regularly monitor mail, detect hardware wallet purchases, and fabricate charges to extort Chinese users’ Bitcoin. SeedSigner solves this by allowing users to assemble a secure signing device from generic, inexpensive parts, avoiding the risk of shipping a branded wallet that might flag them as a target. When privacy violations begin at the local level, SeedSigner can help citizens safeguard their financial freedom by making secure self-custody discreet, accessible, and affordable.
Following .space | Create and Share Follow Packs on Nostr
Following.space is a new tool for nostr that solves one of the protocol’s biggest pain points: finding people worth following in the absence of an algorithm. Created by developer and HRF grantee Calle, the tool lets anyone build and share curated “follow packs” — pre-made lists of nostr users that can be easily distributed across the web. The lists are customizable and can be made based on shared interests, communities, organizations, regions, and more. This makes onboarding new users easier and allows users to curate their feeds to suit their interests. The result is a simple but powerful tool that helps nostr scale more organically by encouraging natural discovery. Enabling free expression and connections without reliance on centralized platforms strengthens human rights and financial freedom in repressive environments. Try it here.
256 Foundation | Releases Ember One Source Code
The 256 Foundation, an open-source Bitcoin mining initiative, released the source code of its new Ember One Bitcoin mining hashboard to the public. A Bitcoin hashboard is a device with multiple chips for performing Bitcoin mining computations. The open-source Ember One only consumes 100 Watts of total power and is modular by design, allowing user customization and the ability to mine discreetly even under autocratic regimes. This is important because it gives individuals a way to access and earn Bitcoin without drawing the attention of officials. For dissidents, mining at home means gaining more control over how they earn, spend, and store their money, all without relying on centralized systems at the whims of dictators.
Btrust and Africa Free Routing | Announce Partnership to Advance African Bitcoin Development
Btrust, a nonprofit advancing Bitcoin development in Africa, awarded a grant to Africa Free Routing, a program within African Bitcoiners, to support five Bitcoin Lightning-focused developer boot camps across the continent in 2025. These bootcamps aim to onboard non-Bitcoin developers into the Bitcoin ecosystem, offering hands-on training, mentorship, and opportunities to contribute to open-source projects. This work strengthens the foundations of freedom tech in Africa, providing tools that allow people to resist financial repression under tyranny. Learn more about the partnership here.
Presidio Bitcoin | Hosting First Hackathon
Presidio Bitcoin, the Bay Area’s first dedicated freedom tech co-working and events space, just announced its first-ever hackathon, which will take place from May 16-17, 2025. This 24-hour hackathon in San Francisco brings together developers and technologists to build and collaborate at the frontier of Bitcoin, AI, and open-source technology. In addition to the hackathon, Presidio is launching a new program offering free three-month access to its workspace for Bitcoin open-source contributors. This is a valuable opportunity to connect with fellow developers, startup founders, and freedom tech advocates in the area. HRF is proud to sponsor this hackathon and is looking forward to how the outcomes might help create better freedom tools for dissidents worldwide. Learn more about the event here.

Bitcoin Nation State Adoption Paradox - Interview with Alex Gladstein
In a recent episode of the Bitcoin Fundamentals podcast, hosted by Preston Pysh, Alex Gladstein, HRF’s chief strategy officer, discusses the complexities of Bitcoin’s new era of adoption. He highlights the paradox where Bitcoin, a tool for individual financial freedom, is being adopted by governments, which some believe to be potentially compromising to its core principles. He emphasizes that while governments may adopt it for strategic or economic reasons, in doing so, they expose their populations to a technology that will ultimately weaken state control over money and advance individual liberty and human rights. Watch the full interview here.
Bitcoin Mining Centralization by b10c
In this report, Bitcoin developer and past HRF grantee b10c documents the growing trend of centralization in Bitcoin mining pools. It shows that over 95% of blocks are now mined by just six Bitcoin mining pools, with Foundry and AntPool controlling roughly 60–70% of the hashrate (the computing power dedicated to the Bitcoin network). This marks a rise in mining pool centralization in recent years. While this hasn’t harmed Bitcoin’s censorship resistance yet, it reduces the number of block template producers. This concentration of template producers poses a potential risk to Bitcoin’s neutrality, which is essential for ensuring access to uncensorable money and protecting human rights in autocratic regimes. HRF has happily supported both Hashpool and Public Pool with recent grants to support smaller, independent pools that help preserve Bitcoin's decentralization. Read the full report here.

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?

2025-05-21 20:00:21I enjoy Jonathan Pageau's perspectives from time to time. He is big on myth and symbolic signs in culture and history. I find this stuff fascinating as well. I watched this video last week, and based on the title, I was thinking... hmm, I wonder if it is a review of Return of the Strong Gods. It wasn't, but it really flows with the thesis of that book. You should read it if you haven't, and before you do, go check out @SimpleStacker's review of it.
Pageau starts the video by talking about the concept of "watching the clown." He uses Ye as the clown. Ye has been a leading indicator in the past when he publicly claimed he was a Christian and began making music and holding church services. Now he's going "off the rails" seemingly with his Hitler songs and art. Clearly, the stigma of Hitler will not last forever. It's hard for us to realize this. At least for someone of my age, but Pageau points out that eventually, the villains of history become less of a stand-in for Satan and more of a purely historical figure. He mentions Alexander the Great as a man who did incredibly evil things, but today we just read about him in school and don't really think about it too much. One day, that will be the way Hitler is viewed. Sure, evil, but the power of using him as the mythical Satan will wane.
The most interesting point I took away from this video, though, was that the post-war consensus was built on a dark secret. Now, it's not a secret to me, but at some point, it was. And this secret is a deep flaw in the current state of the West that keeps affecting us in negative ways. The secret is that in order to defeat Hitler and the Nazis, the West allied itself with the Soviets. Stalin. An incredibly evil man and an ideology that has led to the death and suffering of more humans than the Nazis. This is just a fact, but it's so dark that we don't talk about it.
For many years as I began to study Communism and the Soviet Union I began to question why on earth did the allies align themselves with Stalin. Obviously it was for stratigic reasons. I get it. But the fact that this topic is not really discussed in our culture has had a dark effect. Now, I'm not interested in figuring out if Stalin was more evil than Hitler or if Fascism is worse that Communism. I think this misses the point. The point is that today if soneone has Nazi symbols it is very likely not gonna go well for them but Communist symbols are usually just fine. We see the ideas of Socialism discussed openly without concern. Its popular even. Fascism on the other hand is always (until recently) masked at best.
Today we are seeing more and more people openly talk about this reality, and it is a signal that the WW2 consensus is breaking. As people age out and our collective memory fades, this lie will become more visible because the mythical view of Hitler will fade. This will allow people to be more objective about viewing the decisions of the past. I don't recall the book discussing this directly, but it is an interesting connection for sure.
I recommend watching The World War II Consensus is Breaking Down by Jonathan Pageau.

2025-05-06 08:09:37Macaron returns, fluffs his white linen napkin, and takes his seat at their table, “Thank you, John, for extending my French people such great mercy as to be allowed to transact freely on the Bitcoin blockchain.” He extends his arm out towards a waiter, “Monsieur? Champagne for the three of us please!”
Vrrrm! “I can’t believe we were able to find an American Mustang in this French countryside. I am ripping down these narrow roads!” John celebrates.
“Bloody hell, slow down!” Lily begs as her oversized diamond dangle earrings sway side to side. “You’ve got nothing to prove, John. Big man in your yankee ten-gallon hat. Let’s just get there safely.”
John slows to give her a smoldering look, “Aww, my sweet British compatriot, you care about me!”
“Bollocks! I care about not dying!” Lily retorts. “Now focus on the mission. We need to save a boatload of English border collies — literally. Frenchman Macaron wants to groom them into French poodles!”
John wags a finger off the wheel to reply in his Southern drawl, “However, my sweet Lily flower, my US Hash Force intends to project power to coerce the French for the dogs’ release!”
Lily bats his finger away, “Yes, but may I remind you, my arrogant wanker, geographically challenged friend, MI6’s intel says to steadily power on any miners as His Majesty’s Hash Force may do. The border collies’ barge will take about an hour to flee France, cross the English channel, and safely reach our shores so we don’t want to burst their souffle too quickly. Oh, and the barge is armed with explosives controlled by a remote detonator. When Macaron asks for his bitcoin ransom payment in exchange for the dogs’ release, how do you cowboys plan to help from across the pond?”
John takes both hands off the wheel to flex his biceps, “Shock and awe, Lily. Full Throttle! We’re not giving the French a single sat. Instead, we’re diverting maximum energy to the U.S. Hash Force, of course!”
Lily guffaws, “And where is this sudden surge of readily available power supposed to come from undetected?”
“No need to worry my English crumpet! Our back of the envelope calculations suggest that, with a little help from the Texas of the North, there’s enough flared natural gas in the U.S. to run the entire Bitcoin network!” John proudly replies.
Lily’s jaw drops, “So miners have already stealthily built out the infrastructure to capture wasted natural gas flares for the benefit of the U.S. government, but are waiting to turn them on until commanded to by the U.S. Hash Force?!”
“Yup! As soon as Macaron sees our hash power come online, we’re going to try to start mining blocks on the Bitcoin network to Denial of Service (DOS) attack any UTXOs with a known history of French transactions.”
“A DOS attack, for peace?” Lily asks skeptically.
“Peace through strength, baby! If you don’t comply with America’s dog rights standards, you get censored. America saves British dogs again, and without a single shot fired!”
“Not fair! It’s only because our MI6 chainanalysis intel knows which Bitcoin addresses to censor on the blockchain we suspect belong to Macaron and his government that this plan even has a shot at succeeding. You’re lucky Macaron is even more self-assured than you Americans. That’s the only reason France doesn’t have a Hash Force of its own to project power back!”
John pulls the Mustang up to the front of the fancy French restaurant, Chandelier. Lily grabs her green purse that matches her elegant emerald ball gown, and they head inside to meet Macaron.
John and Lily spot Macaron sitting alone at the white linen table closest to the dance floor. He’s tapping his Louis Vuitton snake leather shoes, checking his Chanel watch, and fluffing his floofy black French Hermès beret. The red French ascot spilling out of his black and white blouse looks ridiculous.
John lets out a big sigh, and Macaron stands with open arms, “Lily, John, welcome to France!” Before John can flinch away, Macaron kisses him on both cheeks. He lifts up Lily’s hand for a kiss, “Mademoiselle.”
John raises his hand, “Waiter! I’ll take a bourbon, neat. And make it a double!” John calls out.
Slap!
“Hey, what was that for, Frenchie?” John asks as he rubs his face.
“Rude American, where are your manners?” Macaron asks as he pulls out a hidden red detonator clipped in the folds of his ascot. “Don’t drive me to prematurely push this button and blow up the boat carrying your English doggies! First, send me my bitcoin ransom payment. Then we can celebrate with drinks!” Macaron demands.
“In your dreams, Frenchie!” John presses his finger to his ear, “Uniform, Sierra, Alpha!”
Macaron turns to Lily and scoffs, “What is this rude American man doing, Lily?”
Annoyed, Lily answers, “Check your bitcoin UTXOs. Notice anything?”
Macaron frantically queries his Bitcoin node remotely from his cellphone and breathes a sigh of relief, “Phew. No, I don’t notice anything at all. All of my unspent bitcoin is still under the control of my government’s private key.”
“And it’ll stay that way, too!” John beats his chest. “You mess with the US, and you get the Hash Force! We just secretly doubled the difficulty to mine a block by turning on all of our miners — as many miners as the entire existing Bitcoin network! Now you’ll have to wait twice as long for your French bitcoin transactions to confirm! That is, unless you release the barge of dogs right now!”
Lily drops down to the table and buries her face in her palms to hide her embarrassment.
Flustered, Macaron furiously types out a long text message with the order to release the barge of English Border Collies to cross the English channel. “There, I’ve let the dogs out! Will you two please excuse me for a moment? I have to place a call with my government to confirm we haven’t lost our property rights to spend our bitcoin.
Beaming with pride, John falls back into his chair at the table. “We did it, Lily! Quick, give the command for His Majesty’s Hash Force to power on so we can 51% attack this guy!”
Lily finally stops rubbing her eyes, “John, that isn’t how any of this works!”
“What do you mean?” he asks.
“Within a 2,016 block difficulty adjustment period, doubling the hash power means the global Bitcoin network will mine new blocks twice as fast, not slower! At least, until the 2,016 block period ends and the difficulty adjusts so miners resume taking on average 10 minutes to generate a valid block. And sure, maybe the US has a political incentive to not collect the fees of any transactions of UTXOs with a known French association, but the rest of the network’s miners will happily profit from the sats you leave in the mempool! But most of all, the Bitcoin network is now just twice as secure from attack!”
John’s double bourbon finally arrives at the table. Selfishly focused on his own glass, he doesn’t bother to stop the waiter in case Lily wants to order a drink of her own. He drinks a big gulp, “But if you give the order for His Majesty’s Hash Force to power on, won’t we have over 51% of the hash power of the Bitcoin network? We can write Macaron’s bitcoin out of existence!”
Lily crosses her arms, “Not exactly. It’s not enough to just surpass half the hashrate. We also need to maintain a higher hashrate than the legacy chain to generate more chain weight to then reorg the other chain when we join the legacy network. We would have to be mining this heavier chain in secret, but in one bombastic order you just completely blew apart our whole plan! Now we’d need some sort of massive collusion somehow between existing miners, and some secret stealth miners, to have any power projection.”
John mutters under his breath, “Frenchie’s been gone a long time. Wonder what he’s up to….”
Macaron returns, fluffs his white linen napkin, and takes his seat at their table, “Thank you, John, for extending my French people such great mercy as to be allowed to transact freely on the Bitcoin blockchain.” He extends his arm out towards a waiter, “Monsieur? Champagne for the three of us please!” Macaron turns to John and Lily, “After my phone call, I am in much better spirits. Though I’m bitter you denied paying our bitcoin ransom, I’m grateful you’re furthering the security of the Bitcoin network.”
In his excitement, Macaron leans forward and claps his hands together, “You two are so lucky to be dining with me tonight. You won’t have to drink that sparkling-wine-swill you have in your home countries. Tonight, you’ll get to have proper champagne, from the Champagne region of France — my treat!”
John grunts in disgust, “Macaron, you can order champagne, but I’ve got my bourbon.”
Lily steps on John’s foot, “Ow! What was that for?” John shrieks.
“Aren’t you going to ask me if I want anything?” Lily asks.
“Huh?” John replies confusedly.
Macaron takes Lily’s hand, “Mademoiselle, in addition to champagne, can I get you anything else?”
Lily recoils her hand back, “Gin martini. Shaken, not stirred.”
“Lily, may I ask you another question?” Macaron asks sweetly.
“Bloody hell, what is it, Macaron?” she responds while rolling her eyes.
“Why do I get the feeling that forgetting to ask you what you’d like to drink isn’t the first time John has neglected to ask you what you wanted?”
Lily’s eyes light up as she leans in closer to Macaron, “Why, yes. This isn’t the first time John’s ever disregarded my needs. You know, he’s always only thinking about himself, his own ego, and he never misses a chance to interrupt me—”
“—That’s not true!” John interrupts.
Lily kicks him under the table, “See what I mean?”
Macaron whisks Lily’s hair behind her ear, “You have such beautiful earrings, Lily. Did John buy those for you?”
“No, John never buys me anything.”
“What do you mean?” John protests.
Lily shrugs him off and Macaron leans in closer to Lily to whisper just loud enough for John to hear, “You know, in my country, men like me know how to show a lady respect.”
John stands up and extends out his hand, “C’mon, Lily. I think it’s time I take you out onto the floor for a dance.”
She shakes her head, so he stomps on her feet under the table.
“Ow!” Lily shrieks.
“I insist,” John presses. “They’re playing my song, Don’t Stop Believin’. C’mon!”
On the dance floor, John pulls Lily close to whisper in her ear, “What are you doing? We’ve finished our mission. Let’s ensure the dogs safely cross the English channel and get out of here! The way you’re flirting with him we’ll never leave!”
Lily blushes, “John, are you that blind? If Macaron is suddenly being sweet to us, then he must be scheming something.”
“What’s that supposed to mean?” John shakes his head. “Look, there’s no time to argue. We can’t risk him blowing up the barge as long as he’s got that remote detonator clipped to his ascot! He’s in a jubilant mood for now, but those French can be so melodramatic. We’ve got to get the detonator to ensure the safety of the dogs until they reach safe harbor at your shores.”
John’s box step dancing pace quickens as he looks over to check on Macaron. He spots him placing an order with the waiter and grits his teeth, “He’s pure evil. He was willing to kill the English border collies if he didn’t get ransom payment for not grooming them into French poodles. Only the threat of our Hash Force forced him to comply with our demand for their release!”
Lily breaks away from John to do a twirl on the dance floor; her elegant flowy green dress tries to keep up. She flips her hair and winks at Macaron, “Maybe I should flirt with him some more? After all, he’s so handsome — and he listens to me!”
John stops dancing and stomps his feet.
“Aww, are you jealous, John?” Lily asks.
“Jealous?!”
Lily floats back to John, digs her nails into the back of his neck, and nibbles on his ear as she whispers, “John, you better dip me on this dance floor! Otherwise, I’m going to ask him to draw me like one of his French girls. C’mon John, Don’t stop believin’!”
Ahem Macaron clears his throat, adjusts his detonator-pinned ascot, and taps Lily on the shoulder.
“Mademoiselle, may I have this dance?”
“Oh, certainly,” she replies. “Better than this brute with two left feet!”
John grunts in dissatisfaction and bolts back to the table.
With Macaron distracted dancing with Lily for what feels like an eternity, John defiantly presses his finger to his ear. “MI6 — status report. What’s taking so long?” he mutters under his breath. “I hate seeing this Frenchie dance with an English lass who deserves so much better. It’s driving me crazy!”
“You just gotta distract him from detonation for ten more minutes,” a British accent replies. “Intel shows the puppy barge armed with explosives has almost reached us across the channel, and then we can safely disarm it.”
“USHF, come in,” John queries.
“We’ve got trouble! The global energy grid has spiked along the Asian seaboard, and among the French alps. Looks like a secret French Hash Force we’ve never detected is colluding with the existing Chinese, Japanese, and Tibetan miners!
They’ve stopped including American-linked bitcoin address transactions in their blocks! Can you politely get him to back down? We’ve already played our power-projection show-of-force card!”
“Ok, I’ll do my best to play nice with Frenchie, but no promises!” John cautions. As he watches Lily and Macaron dance with disdain, a waiter approaches him at the table.
“Here you are, monsieur. Your appetizer.”
“Appetizer? I didn’t order an appetizer! All I ordered was this bourbon.”
“I’m sorry monsieur, but the other gentleman of your party insists. He said he offers this delicacy as a gift. A token of appreciation for the mercy demonstrated today by you, the quote Big American Man enquote.”
John looks on the dance floor and sees Macaron give him a nod with a big wiley grin. Lily gives him the “go-ahead” signal, so John pops one of the hot slimy appetizer balls into his mouth.
“Mhmm! These are tastier than Ma’s Frito Pie!” he shouts as Macaron and Lily walk over to join him back at the table. John continues, “These remind me of the Rocky Mountain oysters we have back at home! Of course, I’m grateful they aren’t, if you know what I mean. What are they, anyways?”
“Escargot,” the Frenchman replies, “a local specialty.”
“Escar-what-now?” John asks.
“Snails!” Lily clarifies.
John gags and spits his half-eaten snail onto the floor. He stands up and slams his ten-gallon cowboy hat on the table. “Ok, that’s it! I’ve had enough! Macaron, stop playing nice. We know you’ve activated some secret alliance with the miners on the other side of the globe! What’re you up to?”
“John, don’t upset him! Think about the puppies!” Lily pleads.
“To heck with the puppies! I’m not letting this man stand up a Hash Force to DOS attack us! You hear that, Macaron? You mess with the best, and we’ll use kinetic force against your miners stashed in the caves of the French alps!” Tsk! Tsk! Tsk! Macaron wags his finger, and pulls out the detonator switch clipped to his ascot.
“Silly pompous American, did you forget I still have the detonator? Did you really think I was going to let you get away with rescuing your hideous English border collies? Life is one giant power projection game, and the way nation states survive is by mutually assured preservation. In exchange for taming the unwieldy fur of Tibetan Mastiffs, Chinese Chow Chows, and Japanese Shih-Tzu and Shiba Inus, these countries pledged their miners to our stealthy French Hash Force when we’re in need. Well, thanks to your little stunt, not only did I find the perfect opportunity to project power back at you arrogant Americans, but also dump these hideous dogs given to me onto your barge, so they’re the British Isles’ problem now!”
“But we’ll be overrun by doges!” Lily gasps in horror.
“Yes, Lily! That’s what you get for partnering with John! What do Americans say?” Macaron asks rhetorically. “That’s right, ‘No dogs left behind!’ But most of all, John, I just wanted one last dance with your girlfriend, and to watch you eat snails!” French nasally honking laughing sounds
Lily shouts back, “I’m not his girlfriend!” She pulls a whistle out of her purse and blows it as hard as she can, but it doesn’t make a sound. John looks at her confused, and Macaron honks even harder. The whole restaurant starts to rumble, and the chandeliers sway from the ceiling.
“What’s this!?” Macaron shouts.
Gradually, then suddenly a stampede of bulldogs comes barreling into the dining room, knocking over all the tables, and tackling Macaron! As he falls, the detonator gets knocked into the air, and Lily catches it just before it hits the floor.
John looks at her, bewildered, and stammers, “You…. you let the Bitcoin dogs out??”
“You think you wankers got all the tricks? The English have a few surprises too! Now c’mon, let’s flee out the back in my British Mini Cooper. And this time, I’m driving!”

I know I will get it and it will become internalized but I just wonder what the designer was thinking when making the flags/commands.

2025-05-21 17:27:46I completely missed this until yesterday. I was listening to our local news talk station and it came up. They had some people that were pretty knowledgeable about prostate cancer on. They talked about other presidents being tested while in office for it. They came to conclusion that it is possible that Biden wasn't having his PSA checked. This is pretty normal for a old dude his age. But it is not normal for a President his age.
My thought is much simpler.
We know his doctors, the media, and his admin were lying about his health when he was in office. Hello! Anyone paying attention and not invested in his regime knew he was declining mentally in front of our very eyes. They covered for him over and over again. Only those that don't pay attention or discounted his critics completely was surprised by his debate performance.
To be clear though, Biden is far from the first president to do this. Wilson, FDR, Kennedy, and Reagan all had issues and they were kept from the public. If we learned these things in school we might actually have a public that thinks critically once and a while.
So, with that in mind do you really think the regime would not withhold medical info about this cancer? Come on. Don't be naive. He clearly was not in charge 100% of the time while in office and the regime wanted to maintain power. Sharing that he had prostate cancer would not be on the menu.
Politics is like a drug that numbs the brain. Because people don't like one party or person they retard their thinking. Its the same thing as happens in sports. Fans of one team see the same play completely differently from the other team's fans. Politics and the investment into parties kills most people's objectivity.
I don't trust liars. It honestly blows my mind how trusting people can be of professional liars. Both parties are full of liars. Trump is a liar and those opposing him are liars. We are drowning in lies. You can vote for a lessor of two evils but never forget what they are.

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.

@ 6830c409:ff17c655
2025-05-04 20:23:30Disclaimer: No artificial intelligence tool has been used to write this article except Grammarly.
There are some things that no one* wants to talk about in a public forum. One of those things is how we clean ourselves after using the toilet. Being a South Asian, I find the bathroom etiquette a bit different from where I am now- in the US. I don't think it is something we have to keep mum about.
[*Mostly]
Earlier, I had read a "Quora WAR" where there was a fierce fight between fellow Western country people vs Indians. Indians advocated using water and the West despised that and advocated using dry wipes/toilet paper. Recently (Yesterday), I remembered this Quora debate and I was curious, when was the commercial production of toilet tissues started? And what were the hygiene methods followed before that.
Obviously, My reading started with Wikipedia. And from there, it was a rabbit-hole. I don't know how, I kept on reading for almost 2 hours. And this piece is out of my understanding of things I read during that mere 2 hours.
We take it for granted today, but toilet paper has a fascinating story spanning thousands of years. From creative ancient solutions to the modern perforated roll, humanity's quest for comfort and cleanliness reveals surprising ingenuity.
Time Before Toilet Paper
Historically, people used whatever they had in their habitat, to clean themselves. This varied from grass, leaves, tree barks, etc. And yes, many civilizations insisted and used water as the main cleaning method. But this was mainly based on the availability of clean water.
Wherever the availability of water was in question, people got creative! Ancient Romans used "tersorium"- basically it is a sea sponge on a stick. They sock it in vinegar or salt water between uses. These were communal.
Greeks preferred smooth pottery fragments with rounded edges. Of course, no one wanted the other end of the digestive tract injured! :D
Early Chinese civilizations wrapped cloth around wooden sticks shaped like spatulas.
Medieval Europeans show their class divisions even in the bathroom! The wealthy used wool, hemp, or even lace. While commoners made do with whatever cloth they had- sometimes, their own sleeves (- today, YUCK!). In the 1700s rural Americas, people turned to nature, using corncobs and seashells.
No matter what we think about these methods, every civilization and every class of people in those valued one thing - Cleanliness.
True Toilet Paper Pioneers
We all know China invented paper somewhere near 100 AD. By the 6th century, Emporer Yandgi's court records show that he used 15,000 sheets of paper annually, just for his personal hygiene!
Early Chinese toilet papers were made from rice straw, hemp, and bamboo. They boiled the material, churned it into a pulp, flattened and dry it, and then cut into shape before using it. By 14th century, the imperial court enjoyed "Perfumed paper sheets". Records show that the royal family alone used almost 0.75 million sheets yearly!!
However, not everyone was happy with this invention. Traveling Muslim merchants described the Chinese practice as "Haraam" (foul), they always preferred using water.
The West Catches Up
Western toilet paper development took longer. Sir John Harrington invented the flushing toilet in 1596, though it would not become common for centuries. By the 1700s, newspapers became a popular bathroom staple.
The commercial breakthrough came only in 1857 when American entrepreneur Joseph Gayetty found a way for the commercial production of toilet papers. But at that time it was sold in another name - "Medicated Paper for Water-Closet". He sold it 500 sheets for 50 cents. Only then the use of "Toilet papers" really arrived in the West.
Rolling into Modern Era
Later in the 19th century, manufacturers found the best and most economical way to produce and store toilet paper - as "Rolls" like we see today. Seth Wheeler of Albany patented perforated wrapping paper in 1871. and the first modern perforated toilet paper roll came out in 1891, making the "tearing" much easier - literally and figuratively! :D
That was the same time home plumbing was improving a lot which resulted in having the toilets inside the home itself. With that, the consumption of toilet paper rose - first as a vanity symbol and later as a common addition to the shopping list.
Big Business in Bathrooms
Brothers - Clarence and Edward Irvin Scott founded Scott Paper Company in Philadelphia in 1879, initially cutting and packaging toilet paper for retailers to sell under their brands. The company grew after 1896 when Arthur Hoyt Scott joined. They started mass-producing their brand of toilet paper. By 1910, they had built the largest paper mill in Chester, marking the industrialization of toilet paper production.
Meanwhile, that old paper made of concoction in China became popular there by the 16th century.
From Luxury to Necessity
We humans always run behind an unknown "comfort". The story of toilet paper is also not so different from that. Imagine using the pottery fragments in place of that "plush quilted ultra-soft scented bathroom tissues". This everyday item we rarely think about represents centuries of innovation and cultural evolution.
Next time you pull a pack of tissue papers from the back aisle of Costco, spare a "thanks" for your ancestors and their corncobs, sea sponges, and pottery fragments.
And maybe soon, you might be "Zapping" to buy tissue papers.
Final Thoughts
The COVID-19 pandemic time gave us some lessons as well as some "FailArmy" videos. One of those videos was people fighting over the last available toilet paper pack in some shop. After the pandemic, there has been a surge in American homes installing Bidet faucets in their bathrooms. A bit late, but the West is now catching up again with the East! :D

2025-05-21 15:52:46In our culture today, people like to have “my truth” as opposed to “your truth.” They want to have teachers who tell them what they want to hear and worship in the way they desire. The Bible predicted these times.
For the time will come when people will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear. (2 Timothy 4:3)
My question is, “do we get to choose what we want to believe about God and how we want to worship Him, or does God tell us what we are to believe and how we are to worship Him?”
The Bible makes it clear that He is who He says He is and He expects obedience and worship according to His commands. We do not get to decide for ourselves.
The woman said to Him, “Sir, I perceive that You are a prophet. Our fathers worshiped in this mountain, and you people say that in Jerusalem is the place where men ought to worship.” Jesus said to her, “Woman, believe Me, an hour is coming when neither in this mountain nor in Jerusalem will you worship the Father. You worship what you do not know; we worship what we know, for salvation is from the Jews. But an hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth; for such people the Father seeks to be His worshipers. God is spirit, and those who worship Him must worship in spirit and truth.” (John 4:19-24) {emphasis mine}
In this passage, Jesus gently corrects the woman for worshipping what she does not know. He also says, “God is spirit, and those who worship Him must worship in spirit and truth.” He states what God is (spirit) and how He must be worshipped “in spirit and truth.” We don’t get to define God however we wish, and we don’t get to worship Him any way we wish. God is who He has revealed Himself to be and we must obey Him and worship Him the way He has commanded.
In this next passage, God makes clear that He is holy and we do not get to worship Him any way we wish. We are to interact with Him in the prescribed manner.
Now Nadab and Abihu, the sons of Aaron, took their respective firepans, and after putting fire in them, placed incense on it and offered strange fire before the Lord, which He had not commanded them. And fire came out from the presence of the Lord and consumed them, and they died before the Lord. Then Moses said to Aaron, “It is what the Lord spoke, saying,
‘By those who come near Me I will be treated as holy,\ And before all the people I will be honored.’ ”
So Aaron, therefore, kept silent. (Leviticus 10:1-3) {emphasis mine}
God had prescribed a particular way to approach Him and only those whom He had chosen (priests of the lineage of Aaron). Nadab and Abihu chose to “do it their way” and paid the price for ignoring God’s command. God set an example with them.
God has been gracious enough to reveal Himself, His character, His power, and His commands to us. If we have truly submitted ourselves to His rule, we should hunger for God’s words so we can know Him better and honor Him in obedience.
But now I come to You; and these things I speak in the world so that they may have My joy made full in themselves. I have given them Your word; and the world has hated them, because they are not of the world, even as I am not of the world. I do not ask You to take them out of the world, but to keep them from the evil one. They are not of the world, even as I am not of the world. Sanctify them in the truth; Your word is truth. (John 17:13-17) {emphasis mine}
In today’s culture, everybody likes to claim their own personal truth, but that isn’t how truth works. The truth is not determined by an individual for themselves. It isn’t even determined by a consensus or majority vote. The truth is the truth even if not one person on earth believes it. God speaks truth and God is truth. Our belief or lack thereof doesn’t change the truth, but our lack of belief in the truth, especially the truth as revealed by God in His word, can negatively affect our relationship with God.
God expects us to study His word so we can obey His commands.
For I did not speak to your fathers, or command them in the day that I brought them out of the land of Egypt, concerning burnt offerings and sacrifices. But this is what I commanded them, saying, ‘Obey My voice, and I will be your God, and you will be My people; and you will walk in all the way which I command you, that it may be well with you.’ Yet they did not obey or incline their ear, but walked in their own counsels and in the stubbornness of their evil heart, and went backward and not forward. Since the day that your fathers came out of the land of Egypt until this day, I have sent you all My servants the prophets, daily rising early and sending them. Yet they did not listen to Me or incline their ear, but stiffened their neck; they did more evil than their fathers. (Jeremiah 7:22-26) {emphasis mine}
Today you rarely see someone bowing down to a golden idol, but that doesn’t mean that we are any better at obeying God’s commands or submitting to His will. We still try to make God in our own image so He is a convenience to us and how we want to live our lives. We still put other things ahead of God — family, work, entertainment, fame, etc. Most of us aren’t any more faithful to God than the Israelites were. Just like the Israelites, we put on the trappings of faith but don’t live according to faith and faithfulness.
And He said to them, “Rightly did Isaiah prophesy of you hypocrites, as it is written:
‘This people honors Me with their lips,\ But their heart is far away from Me.\ **But in vain do they worship Me,\ Teaching as doctrines the precepts of men.’\ Neglecting the commandment of God, you hold to the tradition of men.”
He was also saying to them, “You are experts at setting aside the commandment of God in order to keep your tradition. (Mark 7:6-9) {emphasis mine}
How many “churches” and “Christian” leaders teach people according to the culture instead of according to the Word of God? How many tell people what they want to hear and what makes them feel good instead of what they need to hear — the truth as spoken through the Bible? How many church attenders follow a “Christian” leader more than they follow their Creator, Savior, and God? How many church attenders can recite the words of their leaders better than the Holy Scriptures?
I solemnly charge you in the presence of God and of Christ Jesus, who is to judge the living and the dead, and by His appearing and His kingdom: preach the word; be ready in season and out of season; reprove, rebuke, exhort, with great patience and instruction. For the time will come when they will not endure sound doctrine; but wanting to have their ears tickled, they will accumulate for themselves teachers in accordance to their own desires, and will turn away their ears from the truth and will turn aside to myths. But you, be sober in all things, endure hardship, do the work of an evangelist, fulfill your ministry. (2 Timothy 4:1-5) {emphasis mine}
How can we know if a church leader is rightly preaching God’s word? We can only know if we have read the Bible and studied it. We should be like the Bereans:
Now these were more noble-minded than those in Thessalonica, for they received the word with great eagerness, examining the Scriptures daily to see whether these things were so. (Acts 17:11)
Honestly, I don’t trust any spiritual leader who doesn’t encourage me to search the Scriptures to see whether their words are true. Any leader who puts their own word above the Scriptures is a false teacher. Sadly there are many, maybe more than faithful teachers. Some false teachers are intentionally so, but many have been misled by other false teachers. Their guilt is less, but they don’t do any less harm than those who intentionally mislead.
We need to seek trustworthy teachers who speak according to the Word of God, who quote the Bible to support their opinions, and who seek the good of their followers rather than the submission of their followers.
Do not harden your hearts, as at Meribah,\ As in the day of Massah in the wilderness,
“When your fathers tested Me,\ They tried Me, though they had seen My work.\ For forty years I loathed that generation,\ And said they are a people who err in their heart,\ And they do not know My ways.\ Therefore I swore in My anger,\ Truly they shall not enter into My rest.” (Psalm 95:8-11) {emphasis mine} *Teach me good discernment and knowledge,\ For I believe in Your commandments*.\ Before I was afflicted I went astray,\ But now I keep Your word.\ You are good and do good;\ Teach me Your statutes.\ The arrogant have forged a lie against me;\ *With all my heart I will observe Your precepts*.\ Their heart is covered with fat,\ But I delight in Your law.\ It is good for me that I was afflicted,\ That I may learn Your statutes.\ The law of Your mouth is better to me\ Than thousands of gold and silver pieces. (Psalm 119:66-72) {emphasis mine}
May our Creator God teach us the truth. May He fill our hearts with the desire to be in His word daily and to seek His will. May He do what is necessary to get our attention and turn our hearts and minds fully to Him, so we can learn His statutes and serve Him faithfully, so one day we are blessed to hear, “Well done! Good and faithful servant.”
Trust Jesus.
FYI, I see lack of knowledge of truth and God’s word as one of the biggest problems in the church today; however, it is possible to know the Bible in depth, but not know God. As important as knowledge of Scriptures is, this knowledge (without faith, submission, obedience, and love) is meaningless. Knowledge doesn’t get us to heaven. Even obedience doesn’t get us to heaven. Only faith and submission to our creator God leads to salvation and heaven. That being said, we can’t faithfully serve our God without knowledge of Him and His commands. Out of gratefulness for who He is and what He has done for us, we should seek to know and please Him.

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

ตัวอย่างที่ 3 Bech32 address ที่มีข้อผิดพลาด Address: bc1p9nh05ha8wrljf7ru236awn4t2x0d5ctkkywmv9sclnm4t0av2vgs4k3au7 ข้อผิดพลาดที่ตรวจพบแสดงเป็นตัวหนาและขีดเส้นใต้ สร้างโดยใช้โปรแกรมสาธิตการถอดรหัส bech32 address
-
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 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.

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:

@ ecda4328:1278f072
2025-05-21 11:44:17An honest response to objections — and an answer to the most important question: why does any of this matter?
Last updated: May 21, 2025\ \ 📄 Document version:\ EN: https://drive.proton.me/urls/A4A8Y8A0RR#Sj2OBsBYJFr1\ RU: https://drive.proton.me/urls/GS9AS1NB30#ZdKKb5ackB5e
\ Statement: Deflation is not the enemy, but a natural state in an age of technological progress.\ Criticism: in real macroeconomics, long-term deflation is linked to depressions.\ Deflation discourages borrowers and investors, and makes debt heavier.\ Natural ≠ Safe.
1. “Deflation → Depression, Debt → Heavier”
This is true in a debt-based system. Yes, in a fiat economy, debt balloons to the sky, and without inflation it collapses.
But Bitcoin offers not “deflation for its own sake,” but an environment where you don’t need to be in debt to survive. Where savings don’t melt away.\ Jeff Booth said it clearly:
“Technology is inherently deflationary. Fighting deflation with the printing press is fighting progress.”
You don’t have to take on credit to live in this system. Which means — deflation is not an enemy, but an ally.
💡 People often confuse two concepts:
-
That deflation doesn’t work in an economy built on credit and leverage — that’s true.
-
That deflation itself is bad — that’s a myth.
📉 In reality, deflation is the natural state of a free market when technology makes everything cheaper.
Historical example:\ In the U.S., from the Civil War to the early 1900s, the economy experienced gentle deflation — alongside economic growth, employment expansion, and industrial boom.\ Prices fell: for example, a sack of flour cost \~$1.00 in 1865 and \~$0.50 in 1895 — and there was no crisis, because wages held and productivity increased.
Modern example:\ Consumer electronics over the past 20–30 years are a vivid example of technological deflation:\ – What cost $5,000 in 2000 (e.g., a 720p plasma TV) now costs $300 and delivers 10× better quality.\ – Phones, computers, cameras — all became far more powerful and cheaper at the same time.\ That’s how tech-driven deflation works: you get more for less.
📌 Bitcoin doesn’t make the world deflationary. It just doesn’t fight against deflation, unlike the fiat model that fights to preserve its debt pyramid.\ It stops punishing savers and rewards long-term thinkers.
Even economists often confuse organic tech deflation with crisis-driven (debt) deflation.
\ \ Statement: We’ve never lived in a truly free market — central banks and issuance always existed.\ Criticism: ideological statement.\ A truly “free” market is utopian.\ Banks and monetary issuance emerged in response to crises.\ A market without arbiters is not always fair, especially under imperfect competition.
2. “The Free Market Is a Utopia”
Yes, “pure markets” are rare. But what we have today isn’t regulation — it’s centralized power in the hands of central banks and cartels.
Bitcoin offers rules without rulers. 21 million. No one can change the issuance. It’s not ideology — it’s code instead of trust. And it has worked for 15 years.
💬 People often say that banks and centralized issuance emerged as a response to crises — as if the market couldn’t manage on its own.\ But if a system needs to be “rescued” again and again through money printing… maybe the problem isn’t freedom, but the system itself?
📌 Crises don’t disprove the value of free markets. They only reveal how fragile a system becomes when the price of money is set not by the market, but by a boardroom vote.\ Bitcoin doesn’t magically eliminate crises — it removes the root cause: the ability to manipulate money in someone’s interest.
\ \ Statement: Inflation is an invisible tax, especially on the poor and working class.\ Criticism: partly true: inflation can reduce debt burden, boost employment.\ The state indexes social benefits. Under stable inflation, compensators can work. Under deflation, things might be worse (mass layoffs, defaults).
3. “Inflation Can Help”
Theoretically — yes. Textbooks say moderate inflation can reduce debt burdens and stimulate consumption and jobs.\ But in practice — it works as a stealth tax, especially on those without assets. The wealthy escape — into real estate, stocks, funds.\ But the poor and working class lose purchasing power because their money is held in cash — and cash devalues.
💬 As Lyn Alden says:
“When your money can’t hold value, you’re forced to become an investor — even if you just want to save and live.”
The state may index pensions or benefits — but always with a lag, and always less than actual price increases.\ If bread rises 15% and your payment increase is 5%, you got poorer, even if the number on paper went up.
💥 We live in an inflationary system of everything:\ – Inflationary money\ – Inflationary products\ – Inflationary content\ – And now even inflationary minds
🧠 This is more than just rising prices — it’s a degradation of reality perception. You’re always rushing, everything loses meaning.\ But when did the system start working against you?
📉 What went wrong after 1971?
This chart shows that from 1948 to the early 1970s, productivity and wages grew together.\ But after the end of the gold standard in 1971 — the connection broke. Productivity kept rising, but real wages stalled.
👉 This means: you work more, better, faster — but buy less.
🔗 Source: wtfhappenedin1971.com
When you must spend today because tomorrow it’ll be worth less — that’s rewarding impulse and punishing long-term thinking.
Bitcoin offers a different environment:\ – Savings work\ – Long-term thinking is rewarded\ – The price of the future is calculated, not forced by a printing press
📌 Inflation can be a tool. But in government hands, it became a weapon — a slow, inevitable upward redistribution of wealth.
\ \ Statement: War is not growth, but a reallocation of resources into destruction.
Criticism: war can spur technological leaps (Internet, GPS, nuclear energy — all from military programs). "Military Keynesianism" was a real model.
4. “War Drives R&D”
Yes, wars sometimes give rise to tech spin-offs: Internet, GPS, nuclear power — all originated from military programs.
But that doesn’t make war a source of progress — it makes tech a byproduct of catastrophe.
“War reallocates resources toward destruction — not growth.”
Progress doesn’t happen because of war — it happens despite it.
If scientific breakthroughs require a million dead and burnt cities — maybe you’ve built your economy wrong.
💬 Even Michael Saylor said:
“If you need war to develop technology — you’ve built civilization wrong.”
No innovation justifies diverting human labor, minds, and resources toward destruction.\ War is always the opposite of efficiency — more is wasted than created.
🧠 Bitcoin, on the other hand, is an example of how real R&D happens without violence.\ No taxes. No army. Just math, voluntary participation, and open-source code.
📌 Military Keynesianism is not a model of progress — it’s a symptom of a sick monetary system that needs destruction to reboot.
Bitcoin shows that coordination without violence is possible.\ This is R&D of a new kind: based not on destruction, but digital creation.
Statement: Bitcoin isn’t “Gold 1.0,” but an improved version: divisible, verifiable, unseizable.
Criticism: Bitcoin has no physical value; "unseizability" is a theory;\ Gold is material and autonomous.
5. “Bitcoin Has No Physical Value”
And gold does? Just because it shines?
Physical form is no guarantee of value.\ Real value lies in: scarcity, reliable transfer, verifiability, and non-confiscatability.
Gold is:\ – Hard to divide\ – Hard to verify\ – Expensive to store\ – Easy to seize
💡 Bitcoin is the first store of value in history that is fully free from physical limitations, and yet:\ – Absolutely scarce (21M, forever)\ – Instantly transferable over the Internet\ – Cryptographically verifiable\ – Controlled by no government
🔑 Bitcoin’s value lies in its liberation from the physical.\ It doesn’t need to be “backed” by gold or oil. It’s backed by energy, mathematics, and ongoing verification.
“Price is what you pay, value is what you get.” — Warren Buffett
When you buy bitcoin, you’re not paying for a “token” — you’re gaining access to a network of distributed financial energy.
⚡️ What are you really getting when you own bitcoin?\ – A key to a digital asset that can’t be faked\ – The ability to send “crystallized energy” anywhere on Earth (it takes 10 minutes on the base L1 layer, or instantly via the Lightning Network)\ – A role in a new accounting system that runs 24/7/365\ – Freedom: from banks, borders, inflation, and force
📉 Bitcoin doesn’t require physical value — because it creates value:\ Through trust, scarcity, and energy invested in mining.\ And unlike gold, it was never associated with slavery.
Statement: There’s no “income without risk” in Bitcoin: just hold — you preserve; want more — invest, risk, build.
Criticism: contradicts HODL logic; speculation remains dominant behavior.
6. “Speculation Dominates”
For now — yes. That’s normal for the early phase of a new technology. Awareness doesn’t come instantly.
What matters is not the motive of today’s buyer — but what they’re buying.
📉 A speculator may come and go — but the asset remains.\ And this asset is the only one in history that will never exist again. 21 million. Forever.
📌 Look deeper. Bitcoin has:\ – No CEO\ – No central issuer\ – No inflation\ – No “off switch”\ 💡 It was fairly distributed — through mining, long before ASICs existed. In the early years, bitcoin was spent and exchanged — not hoarded. Only those who truly believed in it are still holding it today.
💡 It’s not a stock. Not a startup. Not someone’s project.\ It’s a new foundation for trust.\ It’s opting out of a system where freedom is a privilege you’re granted under conditions.
🧠 People say: “Bitcoin can be copied.”\ Theoretically — yes.\ Practically — never.
Here’s what you’d need to recreate Bitcoin:\ – No pre-mine\ – A founder who disappears and never sells\ – No foundation or corporation\ – Tens of thousands of nodes worldwide\ – 701 million terahashes of hash power\ – Thousands of devs writing open protocols\ – Hundreds of global conferences\ – Millions of people defending digital sovereignty\ – All that without a single marketing budget
That’s all.
🔁 Everything else is an imitation, not a creation.\ Just like you can’t “reinvent fire” — Bitcoin can only exist once.
Statements:\ **The Russia's '90s weren’t a free market — just anarchic chaos without rights protection.\ **Unlike fiat or even dollars, Bitcoin is the first asset with real defense — from governments, inflation, even thugs.\ *And yes, even if your barber asks about Bitcoin — maybe it's not a bubble, but a sign that inflation has already hit everyone.
Criticism: Bitcoin’s protection isn’t universal — it works only with proper handling and isn’t available to all.\ Some just want to “get rich.”\ None of this matters because:
-
Bitcoin’s volatility (-30% in a week, +50% in a month) makes it unusable for price planning or contracts.
-
It can’t handle mass-scale usage.
-
To become currency, geopolitical will is needed — and without the first two, don’t even talk about the third.\ Also: “Bitcoin is too complicated for the average person.”
7. “It’s Too Complex for the Masses”
It’s complex — if you’re using L1 (Layer 1). But even grandmas use Telegram. In El Salvador, schoolkids buy lunch with Lightning. My barber installed Wallet of Satoshi in minutes right in front of me — and I now pay for my haircut via Lightning.
UX is just a matter of time. And it’s improving. Emerging tools:\ Cashu, Fedimint, Fedi, Wallet of Satoshi, Phoenix, Proton Wallet, Swiss Bitcoin Pay, Bolt Card / CoinCorner (NFC cards for Lightning payments).
This is like the internet in 1995:\ It started with modems — now it’s 4K streaming.
💸 Now try sending a regular bank transfer abroad:\ – you need to type a long IBAN\ – add SWIFT/BIC codes\ – include the recipient’s full physical address (!), compromising their privacy\ – sometimes add extra codes or “purpose of payment”\ – you might get a call from your bank “just to confirm”\ – no way to check the status — the money floats somewhere between correspondent/intermediary banks\ – weekends or holidays? Banks are closed\ – and don’t forget the limits, restrictions, and potential freezes
📌 With Bitcoin, you just scan a QR code and send.\ 10 minutes on-chain = final settlement.\ Via Lightning = instant and nearly free.\ No bureaucracy. No permission. No borders.
8. “Can’t Handle the Load”
A common myth.\ Yes, Bitcoin L1 processes about 7 transactions per second — intentionally. It’s not built to be Visa. It’s a financial protocol, just like TCP/IP is a network protocol. TCP/IP isn’t “fast” or “slow” — the experience depends on the infrastructure built on top: servers, routers, hardware. In the ’90s, it delivered text. Today, it streams Netflix. The protocol didn’t change — the stack did.
Same with Bitcoin: L1 defines rules, security, finality.\ Scaling and speed? That’s the second layer’s job.
To understand scale:
| Network | TPS (Transactions/sec) | | --- | --- | | Visa | up to 24,000 | | Mastercard | \~5,000 | | PayPal | \~193 | | Litecoin | \~56 | | Ethereum | \~20 | | Bitcoin | \~7 |
\ ⚡️ Enter Lightning Network — Bitcoin’s “fast lane.”\ It allows millions of transactions per second, instantly and nearly free.
And it’s not a sidechain.
❗️ Lightning is not a separate network.\ It uses real Bitcoin transactions (2-of-2 multisig). You can close the channel to L1 at any time. It’s not an alternative — it’s a native extension built into Bitcoin.\ Also evolving: Ark, Fedimint, eCash — new ways to scale and add privacy.
📉 So criticizing Bitcoin for “slowness” is like blaming TCP/IP because your old modem won’t stream YouTube.\ The protocol isn’t the problem — it’s the infrastructure.
🛡️ And by the way: Visa crashes more often than Bitcoin.
9. “We Need Geopolitical Will”
Not necessarily. All it takes is the will of the people — and leaders willing to act. El Salvador didn’t wait for G20 approval or IMF blessings. Since 2001, the country had used the US dollar as its official currency, abandoning its own colón. But that didn’t save it from inflation or dependency on foreign monetary policy. In 2021, El Salvador became the first country to recognize Bitcoin as legal tender. Since March 13, 2024, they’ve been purchasing 1 BTC daily, tracked through their public address:
🔗 Address\ 📅 First transaction
This policy became the foundation of their Strategic Bitcoin Reserve (SBR) — a state-led effort to accumulate Bitcoin as a national reserve asset for long-term stability and sovereignty.
Their example inspired others.
In March 2025, U.S. President Donald Trump signed an executive order creating the Strategic Bitcoin Reserve of the USA, to be funded through confiscated Bitcoin and digital assets.\ The idea: accumulate, don’t sell, and strategically expand the reserve — without extra burden on taxpayers.
Additionally, Senator Cynthia Lummis (Wyoming) proposed the BITCOIN Act, targeting the purchase of 1 million BTC over five years (\~5% of the total supply).\ The plan: fund it via revaluation of gold certificates and other budget-neutral strategies.
📚 More: Strategic Bitcoin Reserve — Wikipedia
👉 So no global consensus is required. No IMF greenlight.\ All it takes is conviction — and an understanding that the future of finance lies in decentralized, scarce assets like Bitcoin.
10. “-30% in a week, +50% in a month = not money”
True — Bitcoin is volatile. But that’s normal for new technologies and emerging money. It’s not a bug — it’s a price discovery phase. The world is still learning what this asset is.
📉 Volatility is the price of entry.\ 📈 But the reward is buying the future at a discount.
As Michael Saylor put it:
“A tourist sees Niagara Falls as chaos — roaring, foaming, spraying water.\ An engineer sees immense energy.\ It all depends on your mental model.”
Same with Bitcoin. Speculators see chaos. Investors see structural scarcity. Builders see a new financial foundation.
💡 Now consider gold:
👉 After the gold standard was abandoned in 1971, the price of gold skyrocketed from around \~$300 to over $2,700 (adjusted to 2023 dollars) by 1980. Along the way, it experienced extreme volatility — with crashes of 40–60% even amid the broader uptrend.\ 💡 (\~$300 is the inflation-adjusted equivalent of about $38 in 1971 dollars)\ 📈 Source: Gold Price Chart — Macrotrends\ \ Nobody said, “This can’t be money.” \ Because money is defined not by volatility, but by scarcity, adoption, and trust — which build over time.
📊 The more people save in Bitcoin, the more its volatility fades.
This is a journey — not a fixed state.
We don’t judge the internet by how it worked in 1994.\ So why expect Bitcoin to be the “perfect currency” in 2025?
It grows bottom-up — without regulators’ permission.\ And the longer it survives, the stronger it becomes.
Remember how many times it’s been declared dead.\ And how many times it came back — stronger.
📊 Gold vs. Bitcoin: Supply Comparison
This chart shows the key difference between the two hard assets:
🔹 Gold — supply keeps growing.\ Mining may be limited, but it’s still inflationary.\ Each year, there’s more — with no known cap: new mines, asteroid mining, recycling.
🔸 Bitcoin — capped at 21 million.\ The emission schedule is public, mathematically predictable, and ends completely around 2140.
🧠 Bottom line:\ Gold is good.\ Bitcoin is better — for predictability and scarcity.
💡 As Saifedean Ammous said:
“Gold was the best monetary good… until Bitcoin.”
### While we argue — fiat erodes every day.
No matter your view on Bitcoin, just show me one other asset that is simultaneously:
– immune to devaluation by decree\ – impossible to print more of\ – impossible to confiscate by a centralized order\ – impossible to counterfeit\ – and, most importantly — transferable across borders without asking permission from a bank, a state, or a passport
💸 Try sending $10,000 through PayPal from Iran to Paraguay, or Bangladesh to Saint Lucia.\ Good luck. PayPal doesn't even work there.
Now open a laptop, type 12 words — and you have access to your savings anywhere on Earth.
🌍 Bitcoin doesn't ask for permission.\ It works for everyone, everywhere, all the time.
📌 There has never been anything like this before.
Bitcoin is the first asset in history that combines:
– digital nature\ – predictable scarcity\ – absolute portability\ – and immunity from tyranny
💡 As Michael Saylor said:
“Bitcoin is the first money in human history not created by bankers or politicians — but by engineers.”
You can own it with no bank.\ No intermediary.\ No passport.\ No approval.
That’s why Bitcoin isn’t just “internet money” or “crypto” or “digital gold.”\ It may not be perfect — but it’s incorruptible.\ And it’s not going away.\ It’s already here.\ It is the foundation of a new financial reality.
🔒 This is not speculation. This is a peaceful financial revolution.\ 🪙 This is not a stock. It’s money — like the world has never seen.\ ⛓️ This is not a fad. It’s a freedom protocol.
And when even the barber starts asking about Bitcoin — it’s not a bubble.\ It’s a sign that the system is breaking.\ And people are looking for an exit.
For the first time — they have one.
💼 This is not about investing. It’s about the dignity of work.
Imagine a man who cleans toilets at an airport every day.
Not a “prestigious” job.\ But a crucial one.\ Without him — filth, bacteria, disease.
He shows up on time. He works with his hands.
And his money? It devalues. Every day.
He doesn’t work less — often he works more than those in suits.\ But he can afford less and less — because in this system, honest labor loses value each year.
Now imagine he’s paid in Bitcoin.
Not in some “volatile coin,” but in hard money — with a limited supply.\ Money that can’t be printed, reversed, or devalued by central banks.
💡 Then he could:
– Stop rushing to spend, knowing his labor won’t be worth less tomorrow\ – Save for a dream — without fear of inflation eating it away\ – Feel that his time and effort are respected — because they retain value
Bitcoin gives anyone — engineer or janitor — a way out of the game rigged against them.\ A chance to finally build a future where savings are real.
This is economic justice.\ This is digital dignity.
📉 In fiat, you have to spend — or your money melts.\ 📈 In Bitcoin, you choose when to spend — because it’s up to you.
🧠 In a deflationary economy, both saving and spending are healthy:
You don’t scramble to survive — you choose to create.
🎯 That’s true freedom.
When even someone cleaning floors can live without fear —\ and know that their time doesn’t vanish... it turns into value.
🧱 The Bigger Picture
Bitcoin is not just a technology — it’s rooted in economic philosophy.\ The Austrian School of Economics has long argued that sound money, voluntary exchange, and decentralized decision-making are prerequisites for real prosperity.\ Bitcoin doesn’t reinvent these ideas — it makes them executable.
📉 Inflation doesn’t just erode savings.\ It quietly destroys quality of life.\ You work more — and everything becomes worse:\ – food is cheaper but less nutritious\ – homes are newer but uglier and less durable\ – clothes cost more but fall apart in months\ – streaming is faster, but your attention span collapses\ This isn’t just consumerism — it’s the economics of planned obsolescence.
🧨 Meanwhile, the U.S. debt has exceeded 3x its GDP.\ And nobody wants to buy U.S. bonds anymore — so the U.S. has to buy its own debt.\ Yes: printing money to buy the IOUs you just printed.\ This is the endgame of fiat.
🎭 Bonds are often sold as “safe.”\ But in practice, they are a weapon — especially abroad.\ The U.S. and IMF give loans to developing countries.\ But when those countries can’t repay (due to rigged terms or global economic headwinds), they’re forced to sell land, resources, or strategic assets.\ Both sides lose: the debtor collapses under the weight of debt, while the creditor earns resentment and instability.\ This isn’t cooperation — it’s soft colonialism enabled by inflation.
📌 Bitcoin offers a peaceful exit.\ A financial system where money can’t be created out of thin air.\ Where savings work.\ Where dignity is restored — even for those who clean toilets.

2025-05-04 06:56:33Building A Second Brain (BASB) ist eine Methode, mit der man Ideen, Einsichten und Vernetzungen, die man durch seine Erfahrungen gewonnen hat, systematisch speichert und die jeder Zeit abrufbar sind. Kurz, BASB erweitert das Gedächtnis mit Hilfe moderner digitaler Werkzeuge und Netzwerke. Die Kernidee ist, dass man durch diese Verlagerung sein biologisches Gehirn befreit, um frei denken zu können, seiner Kreativität freien Lauf zu geben oder einfach im Moment sein kann.
Die Methode besteht aus drei Grundschritten: dem Sammeln von Ideen und Erkenntnissen, dem Vernetzen dieser Ideen und Erkenntnisse und dem Erschaffen konkreter Ergebnisse.
Sammeln: Der erste Schritt beim Aufbau eines Second Brains ist das «Sammeln» der Ideen und Erkenntnisse, die genug wichtig oder interessant sind, um sie festzuhalten. Dafür wird als Organisationsstruktur P.A.R.A empfohlen.
Vernetzen: Sobald man angefangen hat, sein persönliches Wissen strukturiert zu sammeln, wird man anfangen, Muster und Verbindungen zwischen den Ideen und Erkenntnissen zu erkennen. Ab dieser Stelle verwende ich parallel die Zettelkastenmethode (ZKM)
Erschaffen: All das Erfassen, Zusammenfassen, Verbinden und Strukturieren haben letztlich das Ziel: Konkrete Ergebnisse in der realen Welt zu erschaffen.
PARA ist die Organisationsstruktur, die auf verschiedenen Endgeräten einsetzt werden kann, um digitale Informationen immer nach dem gleichen Schema abzulegen. Seien es Informationen, Notizen, Grafiken, Videos oder Dateien, alles hat seinen festen Platz und kann anhand von vier Kategorien bzw. „Buckets“ kategorisiert werden.
PARA steht dabei für: * Projekte * Areas * Ressourcen * Archiv
Projekte (engl. Projects) sind kurzfristige Bemühungen in Arbeit und Privatleben. Sie sind das, woran Du aktuell arbeitest. Sie haben einige für die Arbeit förderliche Eigenschaften: * Sie haben einen Anfang und ein Ende (im Gegensatz zu einem Hobby oder einem Verantwortungsbereich). * Sie haben ein konkretes Ergebnis, dass erreicht werden soll und bestehen aus konkreten Schritten, die nötig und zusammen hinreichend sind, um dieses Ziel zu erreichen, entspricht GTD von David Allen
Verantwortungsbereiche (engl. Areas) betreffen alles, was man langfristig im Blick behalten will. Sie unterscheidet von Projekten, dass man bei ihnen kein Ziel verfolgt, sondern einem Standard halten will. Sie sind dementsprechend nicht befristet. Man könnte sagen, dass sie einen Anspruch an uns selbst und unsere Lebenswelt darstellen.
Ressourcen (engl. Resources) sind Themen, die allenfalls langfristig relevant oder nützlich werden könnten. Sie sind eine Sammelkategorie für alles, was weder Projekt noch Verantwortungsbereich ist. Es sind: * Themen, die interessant sind. (English: Topic) * Untersuchungsgegenständige, die man erforschen will. (Englisch: Subject) * Nützliche Informationen für den späteren Gebrauch.
Das Archiv ist für alles Inaktive aus den obigen drei Kategorien. Es ist ein Lager für Beendetes und Aufgeschobenes.
Das System PARA ist eine nach zeitlicher Handlungsrelevanz angeordnete Ablage. Projekte kommen vor den Verantwortungsbereichen, weil sie einen kurz- bis mittelfristigen Zeithorizont haben, Verantwortungsbereiche dagegen einen unbegrenzten Zeithorizont. Ressourcen und Archiv bilden die Schlusslichter, weil sie gewöhnlich weder Priorität haben, noch dringend sind.

Come now, take a walk with me…
The Traveller 02: Jerusalem Old City
The bus slowly lurches up the winding and steep embankment. We can finally start to see the craggy tops of buildings peaking out over the ridge in the foreground distance. We have almost reached it. Jerusalem, the City on the Hill.
https://i.nostr.build/e2LpUKEgGBwfveGi.jpg
Our Israeli tour guide speaks over the mic to draw our attention to the valley below us instead - “This is the the Valley of Gehenna, the Valley of the Moloch,” he says. “In ancient times, the pagans who worshiped Moloch used this place for child sacrifice by fire. Now, imagine yourself, an early Hebrew, sitting atop the hill, looking down in horror. This is the literal Valley of The Shadow of Death, the origin of the Abrahamic concept of Hell.” Strong open - this is going to be fun.
https://i.nostr.build/5F29eBKZYs4bEMHk.jpg
Inside the Old City, our guide - a chubby, cherub-faced intelligence type on some sort of punishment duty, deputized to babysit foreigners specifically because he reads as so dopey and disarming - points out various Judeo-Christian sites on a map, his tone subtly suggesting which places are most suggested, or perhaps, permitted…
https://i.nostr.build/J44fhGWc9AZ5qpK4.jpg
https://i.nostr.build/3c0jh09nx6d5cEdt.jpg
Walking, we reach Judaism’s Kotel, the West Wall - massive, grand, and ancient, whispering of the Eternal. Amongst the worshipers, we touch the warm, dry limestone and, if we like, place written prayers into the wall's smaller cracks. A solemn and yearning ghost fills the place - but whose it is, I'm not sure.  https://i.nostr.build/AjDwA0rFiFPlrw1o.jpg
Just above the Kotel, Islam’s Dome of the Rock can be seen, its golden cap blazing in the sun. I ask our guide about visiting the dome. He cuts a heavy eyeroll in my direction - it seems I’ve outed myself as my group’s “that guy.” His face says more than words ever could, “Oy vey, there’s one in every group…”
“Why would anyone want to go there? It is a bit intense, no?” Still, I press. “Well, it is only open to tourists on Tuesday and Thursdays…” It is Tuesday. “And even then, visiting only opens from 11:30…” It is 11:20. As it becomes clear to him that I don't intend to drop this...“Fine!” he relents, with a dramatic flaring of the hands and an uniquely Israeli sigh, “Go there if you must. But remember, the bus leaves at 1PM. Good luck...” Great! Totally not ominous at all.
https://i.nostr.build/6aBhT61C28QO9J69.jpg
The checkpoint for the sole non-Muslim entrance leading up to the Dome is administered by several gorgeous and statuesque, assault rifle clad, Ethiop-Israeli female soldiers. In this period of relative peace and calm, they feel lax enough to make a coy but salacious game of their “screening” the men in line. As I observe, it seems none doth protest...
https://i.nostr.build/jm8F3pUp9EXqPRkN.jpg
Past the gun-totting Sirens, a long wooden rampart leads up to the Temple Mount, The Mount of the House of the Holy, al-Ḥaram al-Sharīf, The Noble Sanctuary, The Furthest Mosque, the site of the Dome of the Rock and the al-Masjid al-Asqa.
https://i.nostr.build/DoS0KIkrVN0yiVJ0.jpg
On the Mount, the Dome dominates all views. To those interested in pure expressions of beauty, the Dome is, undeniably, a thing of absolute glory. I pace the grounds, snapping what pictures I can. I pause to breathe and to let the electric energy of the setting wash over me.
https://i.nostr.build/0BQYLwpU291q2fBt.jpg
https://i.nostr.build/yCxfB1V8eAcfob93.jpg
It’s 12:15 now, I decide to head back. Now, here is what they don’t tell you. The non-Muslin entrance from the West Wall side is a one-way deal. Leaving the Dome plaza dumps you out into the back alley bazaar of Old City’s Muslim district. And so it is. I am lost.
https://i.nostr.build/XnQ5eZgjeS1UTEBt.jpg
https://i.nostr.build/EFGD5vgmFx5YYuH4.jpg
I run through the Muslim quarter, blindly turning down alleyways that seem to be taking me in the general direction of where I need to be - glimpses afforded by the city’s uneven elevation and cracks in ancient stone walls guiding my way.
https://i.nostr.build/mWIEAXlJfdqt3nuh.jpg
In a final act of desperation and likely a significant breach of Israeli security protocol, I scale a low wall and flop down back on the side of things where I'm “supposed” to be. But either no one sees me or no one cares. Good luck, indeed.
I make it back to my group - they are not hard to find, a bunch of MBAs in “business casual” travel attire and a tour guide wearing a loudly colored hat and jacket - with just enough time to still visit the Church of the Holy Sepulcher.
https://i.nostr.build/3nFvsXdhd0LQaZd7.jpg
https://i.nostr.build/sKnwqC0HoaZ8winW.jpg
Inside, a chaotic and dizzying array of chapels, grand domed ceilings, and Christian relics - most notably the Stone of Anointing, commemorating where Christ’s body was prepared for burial and Tomb of Christ, where Christ is said to have laid for 3 days before Resurrection.
https://i.nostr.build/Lb4CTj1dOY1pwoN6.jpg
https://i.nostr.build/LaZkYmUaY8JBRvwn.jpg
In less than an hour, one can traverse from the literal Hell, to King David’s Wall, The Tomb of Christ, and the site of Muhammad’s Ascension. The question that stays with me - What is it about this place that has caused so many to turn their heads to the heavens and cry out for God? Does he hear? And if he answers, do we listen?

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.

2025-05-16 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.

2025-05-03 21:54:45Introduction
Me and Fishcake have been working on infrastructure for Noswhere and Nostr.build. Part of this involves processing a large amount of Nostr events for features such as search, analytics, and feeds.
I have been recently developing
nosdex
v3, a newer version of the Noswhere scraper that is designed for maximum performance and fault tolerance using FoundationDB (FDB).Fishcake has been working on a processing system for Nostr events to use with NB, based off of Cloudflare (CF) Pipelines, which is a relatively new beta product. This evening, we put it all to the test.
First preparations
We set up a new CF Pipelines endpoint, and I implemented a basic importer that took data from the
nosdex
database. This was quite slow, as it did HTTP requests synchronously, but worked as a good smoke test.Asynchronous indexing
I implemented a high-contention queue system designed for highly parallel indexing operations, built using FDB, that supports: - Fully customizable batch sizes - Per-index queues - Hundreds of parallel consumers - Automatic retry logic using lease expiration
When the scraper first gets an event, it will process it and eventually write it to the blob store and FDB. Each new event is appended to the event log.
On the indexing side, a
Queuer
will read the event log, and batch events (usually 2K-5K events) into one work job. This work job contains: - A range in the log to index - Which target this job is intended for - The size of the job and some other metadataEach job has an associated leasing state, which is used to handle retries and prioritization, and ensure no duplication of work.
Several
Worker
s monitor the index queue (up to 128) and wait for new jobs that are available to lease.Once a suitable job is found, the worker acquires a lease on the job and reads the relevant events from FDB and the blob store.
Depending on the indexing type, the job will be processed in one of a number of ways, and then marked as completed or returned for retries.
In this case, the event is also forwarded to CF Pipelines.
Trying it out
The first attempt did not go well. I found a bug in the high-contention indexer that led to frequent transaction conflicts. This was easily solved by correcting an incorrectly set parameter.
We also found there were other issues in the indexer, such as an insufficient amount of threads, and a suspicious decrease in the speed of the
Queuer
during processing of queued jobs.Along with fixing these issues, I also implemented other optimizations, such as deprioritizing
Worker
DB accesses, and increasing the batch size.To fix the degraded
Queuer
performance, I ran the backfill job by itself, and then started indexing after it had completed.Bottlenecks, bottlenecks everywhere
After implementing these fixes, there was an interesting problem: The DB couldn't go over 80K reads per second. I had encountered this limit during load testing for the scraper and other FDB benchmarks.
As I suspected, this was a client thread limitation, as one thread seemed to be using high amounts of CPU. To overcome this, I created a new client instance for each
Worker
.After investigating, I discovered that the Go FoundationDB client cached the database connection. This meant all attempts to create separate DB connections ended up being useless.
Using
OpenWithConnectionString
partially resolved this issue. (This also had benefits for service-discovery based connection configuration.)To be able to fully support multi-threading, I needed to enabled the FDB multi-client feature. Enabling it also allowed easier upgrades across DB versions, as FDB clients are incompatible across versions:
FDB_NETWORK_OPTION_EXTERNAL_CLIENT_LIBRARY="/lib/libfdb_c.so"
FDB_NETWORK_OPTION_CLIENT_THREADS_PER_VERSION="16"
Breaking the 100K/s reads barrier
After implementing support for the multi-threaded client, we were able to get over 100K reads per second.
You may notice after the restart (gap) the performance dropped. This was caused by several bugs: 1. When creating the CF Pipelines endpoint, we did not specify a region. The automatically selected region was far away from the server. 2. The amount of shards were not sufficient, so we increased them. 3. The client overloaded a few HTTP/2 connections with too many requests.
I implemented a feature to assign each
Worker
its own HTTP client, fixing the 3rd issue. We also moved the entire storage region to West Europe to be closer to the servers.After these changes, we were able to easily push over 200K reads/s, mostly limited by missing optimizations:
It's shards all the way down
While testing, we also noticed another issue: At certain times, a pipeline would get overloaded, stalling requests for seconds at a time. This prevented all forward progress on the
Worker
s.We solved this by having multiple pipelines: A primary pipeline meant to be for standard load, with moderate batching duration and less shards, and high-throughput pipelines with more shards.
Each
Worker
is assigned a pipeline on startup, and if one pipeline stalls, other workers can continue making progress and saturate the DB.The stress test
After making sure everything was ready for the import, we cleared all data, and started the import.
The entire import lasted 20 minutes between 01:44 UTC and 02:04 UTC, reaching a peak of: - 0.25M requests per second - 0.6M keys read per second - 140MB/s reads from DB - 2Gbps of network throughput
FoundationDB ran smoothly during this test, with: - Read times under 2ms - Zero conflicting transactions - No overloaded servers
CF Pipelines held up well, delivering batches to R2 without any issues, while reaching its maximum possible throughput.
Finishing notes
Me and Fishcake have been building infrastructure around scaling Nostr, from media, to relays, to content indexing. We consistently work on improving scalability, resiliency and stability, even outside these posts.
Many things, including what you see here, are already a part of Nostr.build, Noswhere and NFDB, and many other changes are being implemented every day.
If you like what you are seeing, and want to integrate it, get in touch. :)
If you want to support our work, you can zap this post, or register for nostr.land and nostr.build today.

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.

2025-05-02 22:24:59Its been six long months of refactoring code and building out to the applesauce packages but the app is stable enough for another release.
This update is pretty much a full rewrite of the non-visible parts of the app. all the background services were either moved out to the applesauce packages or rewritten, the result is that noStrudel is a little faster and much more consistent with connections and publishing.
New layout
The app has a new layout now, it takes advantage of the full desktop screen and looks a little better than it did before.
Removed NIP-72 communities
The NIP-72 communities are no longer part of the app, if you want to continue using them there are still a few apps that support them ( like satellite.earth ) but noStrudel won't support them going forward.
The communities where interesting but ultimately proved too have some fundamental flaws, most notably that all posts had to be approved by a moderator. There were some good ideas on how to improve it but they would have only been patches and wouldn't have fixed the underlying issues.
I wont promise to build it into noStrudel, but NIP-29 (relay based groups) look a lot more promising and already have better moderation abilities then NIP-72 communities could ever have.
Settings view
There is now a dedicated settings view, so no more hunting around for where the relays are set or trying to find how to add another account. its all in one place now
Cleaned up lists
The list views are a little cleaner now, and they have a simple edit modal
New emoji picker
Just another small improvement that makes the app feel more complete.
Experimental Wallet
There is a new "wallet" view in the app that lets you manage your NIP-60 cashu wallet. its very experimental and probably won't work for you, but its there and I hope to finish it up so the app can support NIP-61 nutzaps.
WARNING: Don't feed the wallet your hard earned sats, it will eat them!
Smaller improvements
- Added NSFW flag for replies
- Updated NIP-48 bunker login to work with new spec
- Linkfy BIPs
- Added 404 page
- Add NIP-22 comments under badges, files, and articles
- Add max height to timeline notes
- Fix articles view freezing on load
- Add option to mirror blobs when sharing notes
- Remove "open in drawer" for notes

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.
