In a vast digital realm, two cities stood side by side: the towering, flashing metropolis of Feedia, and the decentralized, quiet city of Nostra.

Feedia was loud—blinding, buzzing, and always on. Screens plastered every wall, whispering the latest trends into citizens’ ears. But in this city, what you saw wasn’t up to you. It was determined by a towering, unseen force known as The Algorithm. It didn’t care what was true, meaningful, or helpful—only what would keep your eyes glued and your attention sold.

In Feedia, discovery wasn’t earned. It was assigned.

And worse—there was a caste system. To have a voice, you needed a Blue Check—a glowing badge that marked you as “worthy.” To get one, you had to pay or play. Pay monthly dues to the high towers or entertain The Algorithm enough to be deemed “valuable.” If you refused or couldn’t afford it, your voice was cast into the noise—buried beneath outrage bait and celebrity screams.

The unmarked were like ghosts—speaking into the void while the checked dined in Algorithm-favored towers. It was a digital monarchy dressed up as a democracy.

Then, there was Nostra.

There were no glowing checkmarks in Nostra—just signal. Every citizen had a light they carried, one that grew brighter the more they contributed: thoughtful posts, reshared ideas, built tools, or boosted others. Discovery was based not on payment or privilege, but participation and value.

In Nostra, you didn’t rise because you paid the gatekeeper—you rose because others lifted you. You weren’t spoon-fed; you sought, you found, you earned attention. It was harder, yes. But it was real.

And slowly, some in Feedia began to awaken. They grew tired of being fed fast-food content and ignored despite their voices. They looked across the river to Nostra, where minds weren’t bought—they were built.

And one by one, they began to cross.

There 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. 🫡

One 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.

Dear friend,

it seems like you have decided to turn your back on those walled gardens and set sails to enter uncharted territory. A world without walls, an open world, a world of beautiful chaos. At least for today, I don't intend guiding you out of the safe harbour onto the open, endless sea. Today, my only intent is sharing a few thoughts, before you depart.

As a wise man on Madeira once said, it's not so much about having the right answers, it's about asking the right questions. While I'm not certain whether I have found the right questions myself by now, let me share the current set with you:

• What causes the discomfort that drives you out of the walled garden onto the open sea?

• Are you trying to transfer from one walled garden to the next one, where the difference being a slightly friendlier colour on the wall?

• What are you hoping to find on the open sea that walled gardens cannot provide?

• What are you willing to sacrifice for freedom (of speech)?

• What will you need to keep the ship afloat?

• How will you react when you find yourself in the middle of a storm?

I sincerely believe that it's worthwile taking a step back before departing to reflect on the big picture and the underlying paradigm shift between walled gardens and nostr. This is not about building competitors to broken systems, this is not about mimicking centralised services, this is not about repeating the same mistakes over and over.

This is about building a new world, an open world without walled gardens and data silos.

Onwards!

The evolution of development environments is incredibly rich and complex and reflects a continuous drive towards greater efficiency, consistency, isolation, and collaboration. It's a story of abstracting away complexity and standardizing workflows.

Phase 1: The Bare Metal & Manual Era (Early 1970s - Late 1990s)

1. Direct OS Interaction / Bare Metal Development:

   • Description: Developers worked directly on the operating system's command line or a basic text editor. Installation of compilers, interpreters, and libraries was a manual, often arcane process involving downloading archives, compiling from source, and setting environment variables. "Configuration drift" (differences between developer machines) was the norm.
   • Tools: Text editors (Vi, Emacs), command-line compilers (GCC), Makefiles.
   • Challenges: Extremely high setup time, dependency hell, "works on my machine" syndrome, difficult onboarding for new developers, lack of reproducibility. Version control was primitive (e.g., RCS, SCCS).

2. Integrated Development Environments (IDEs) - Initial Emergence:

   • Description: Early IDEs (like Turbo Pascal, Microsoft Visual Basic) began to integrate editors, compilers, debuggers, and sometimes GUI builders into a single application. This was a massive leap in developer convenience.
   • Tools: Turbo Pascal, Visual Basic, early Visual Studio versions.
   • Advancement: Improved developer productivity, streamlined common tasks. Still relied on local system dependencies.

Phase 2: Towards Dependency Management & Local Reproducibility (Late 1990s - Mid-2000s)

1. Basic Build Tools & Dependency Resolvers (Pre-Package Managers):

   • Description: As projects grew, manual dependency tracking became impossible. Tools like Ant (Java) and early versions of autoconf/make for C/C++ helped automate the compilation and linking process, managing some dependencies.
   • Tools: Apache Ant, GNU Autotools.
   • Advancement: Automated build processes, rudimentary dependency linking. Still not comprehensive environment management.

2. Language-Specific Package Managers:

   • Description: A significant leap was the emergence of language-specific package managers that could fetch, install, and manage libraries and frameworks declared in a project's manifest file. Examples include Maven (Java), npm (Node.js), pip (Python), RubyGems (Ruby), Composer (PHP).
   • Tools: Maven, npm, pip, RubyGems, Composer.
   • Advancement: Dramatically simplified dependency resolution, improved intra-project reproducibility.
   • Limitation: Managed language-level dependencies, but not system-level dependencies or the underlying OS environment. Conflicts between projects on the same machine (e.g., Project A needs Python 2.7, Project B needs Python 3.9) were common.

Phase 3: Environment Isolation & Portability (Mid-2000s - Early 2010s)

1. Virtual Machines (VMs) for Development:

   • Description: To address the "it works on my machine" problem stemming from OS-level and system-level differences, developers started using VMs. Tools like VMware Workstation, VirtualBox, and later Vagrant (which automated VM provisioning) allowed developers to encapsulate an entire OS and its dependencies for a project.
   • Tools: VMware, VirtualBox, Vagrant.
   • Advancement: Achieved strong isolation and environment reproducibility (a true "single environment" for a project).
   • Limitations: Resource-heavy (each VM consumed significant CPU, RAM, disk space), slow to provision and boot, difficult to share large VM images.

2. Early Automation & Provisioning Tools:

   • Description: Alongside VMs, configuration management tools started being used to automate environment setup within VMs or on servers. This helped define environments as code, making them more consistent.
   • Tools: Chef, Puppet, Ansible.
   • Advancement: Automated provisioning, leading to more consistent environments, often used in conjunction with VMs.

Phase 4: The Container Revolution & Orchestration (Early 2010s - Present)

1. Containerization (Docker):

   • Description: Docker popularized Linux Containers (LXC), offering a lightweight, portable, and efficient alternative to VMs. Containers package an application and all its dependencies into a self-contained unit that shares the host OS kernel. This drastically reduced resource overhead and startup times compared to VMs.
   • Tools: Docker.
   • Advancement: Unprecedented consistency from development to production (Dev/Prod Parity), rapid provisioning, highly efficient resource use. Became the de-facto standard for packaging applications.

2. Container Orchestration:

   • Description: As microservices and container adoption grew, managing hundreds or thousands of containers became a new challenge. Orchestration platforms automated the deployment, scaling, healing, and networking of containers across clusters of machines.
   • Tools: Kubernetes, Docker Swarm, Apache Mesos.
   • Advancement: Enabled scalable, resilient, and complex distributed systems development and deployment. The "environment" started encompassing the entire cluster.

Phase 5: Cloud-Native, Serverless & Intelligent Environments (Present - Future)

1. Cloud-Native Development:

   • Description: Leveraging cloud services (managed databases, message queues, serverless functions) directly within the development workflow. Developers focus on application logic, offloading infrastructure management to cloud providers. Containers become a key deployment unit in this paradigm.
   • Tools: AWS Lambda, Azure Functions, Google Cloud Run, cloud-managed databases.
   • Advancement: Reduced operational overhead, increased focus on business logic, highly scalable deployments.

2. Remote Development & Cloud-Based IDEs:

   • Description: The full development environment (editor, terminal, debugger, code) can now reside in the cloud, accessed via a thin client or web browser. This means developers can work from any device, anywhere, with powerful cloud resources backing their environment.
   • Tools: GitHub Codespaces, Gitpod, AWS Cloud9, VS Code Remote Development.
   • Advancement: Instant onboarding, consistent remote environments, access to high-spec machines regardless of local hardware, enhanced security.

3. Declarative & AI-Assisted Environments (The Near Future):

   • Description: Development environments will become even more declarative, where developers specify what they need, and AI/automation tools provision and maintain it. AI will proactively identify dependency issues, optimize resource usage, suggest code snippets, and perform automated testing within the environment.
   • Tools: Next-gen dev container specifications, AI agents integrated into IDEs and CI/CD pipelines.
   • Prediction: Near-zero environment setup time, self-healing environments, proactive problem identification, truly seamless collaboration.

เมื่อพูดถึง 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

The 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

It's wild. I just proved I can build #nostr 'wallet' where I can store the encrypted tokens in a Germany relay and make the lightning payment out of a Singapore mint. All using a #nsec that never leaves my machine. https://primal.net/e/note15l02rf4r474ck04mlrxxfagyl0z6t04ltsugf9dtph4xxhzfnd4sqpk74n

I’ve proven to myself that a #nostr wallet can exist across time and space, independently of any one app, server or custodian. The only thing which controls the ‘wallet’ is the generation and control of an #nsec which is free to exist within or flee any jurisdiction.

In my mind, this lays to rest the notion that a wallet needs to be an app, service, or anything that can be captured commercially or by the state. https://primal.net/e/note13nwsh852x9tfex2jade6vwymhhct8zussxr4zwy7uag24hjc9stq0xsxaf

https://image.nostr.build/07dd1b56d6bb60b13cfe6c19d9384bc3ef198d01af4be9a5c544f791b80b746a.png

I am thinking about coining the term “nsac” to refer to a wallet-like thing that can exist on #nostr holding your valuable things, such as ecash tokens. I have already implemented a prototype #cashu ecash wallet which looks to be promising.

So you would have:

npub - your identity

nsec - your private key

nsac - your valuables

Your #nsac could be the same as your #nsec but better case is to generate as many #nsacs as required.

Happy to hear feedback!

For reference, what a ‘sac’ is in the biological sense:

A sac is a biological term referring to a pouch or cavity in an organism that is typically enclosed and may contain fluid, air, or other substances. Sacs can serve various functions depending on their location and role in the body, such as protecting a developing embryo, facilitating the exchange of gases in the lungs, or reducing friction between moving parts in joints

Suppose you have a small mom-and-pop shop selling bananas, your bananas are of the highest quality, you plant the banana trees yourself, you water them daily, take great care of everything, and still select only the top 1% of bananas to sell.

Your customers love it, there's no place where they can get better bananas, but due to the fact that you spend so much time, your bananas have to be more expensive, so despite the higher quality, you don't make as much money as you think you should; surely you can get a little more of the market if you adopt some of the strategies that work for your competitors.

So you look across the street, and what do you know? Their bananas are of significantly worse quality than yours, but they're not just selling bananas, they're selling apples too, so you think to yourself, "what if I sold apples? Maybe my apples won't be the best in the market, but nobody can beat my bananas!"

You start planting apple trees, and after a while you're able go sell slightly better than average apples, but by doing so you neglect your bananas ever so slightly.

Most of your existing customers don't notice, you still have the best bananas in town, they don't notice the slight drop in quality. And now that you're selling apples too you're making more money, and more customers come to you.

But you notice that there's a new store now that's selling oranges, and people are buying them. So surely you need oranges too, so you can make some extra money.

You plant a few orange trees, but find yourself spending so much time tending to the oranges and apples that you can't devote the same time and love to your bananas.

You are making a bit of extra cash from the new customers, business is going well, but you don't have time for anything else anymore. You no free time anymore, you are overworked and your health is getting worse.

But you can't stop now that business is going well, you are making so much more, yeah maybe you don't have the same bananas anymore, but you do have slightly above average apples and oranges that have attracted so many customers.

You suddenly fall ill, you've overworked yourself and you are stuck at a hospital for a while.

When you come back to your store, a few of your customers are back, but not all of them, so you think of more ideas, mandarins, kiwi, watermelons, you can grow it all, but you're gonna hire a bunch of people to help you so you don't fall ill again.

One thing leads to another and you are making more money than ever, but strangely you don't hear your customers praising your bananas anymore.

So you take one of your bananas, peel it, and as you taste it, a wave of disappointment hits you.

Your bananas are now just as bad as everyone else's; you gave in to the tyranny of the marginal customer.

You make a lot of money now, but your flagship product is long gone, you are now just another Fruitseller.

Since it's Bitcoin Pizza Day, I made a Bitcoin pizza!

To give it a Japanese twist, I made it a mentaiko pizza (※ mentaiko = spicy cod roe, a popular Japanese ingredient often used in pasta or rice dishes). For the Bitcoin logo, I used a salmon terrine.

Salmon Terrine

I cut out the "B" logo using hanpen (※ hanpen = a soft, white Japanese fish cake made from fish paste and yam). Tip: You can also cut a colored plastic folder into the "B" shape and place it on top as a stencil — makes it easier!

I blended salmon, hanpen, milk, egg, and a bit of salt in a food processor, poured it into a container, and baked it in a water bath.

Pizza Dough

I mixed bread flour, dry yeast, salt, olive oil, and water, then kneaded it with determination! Let it rise for about an hour until fluffy.

Mentaiko Mayo Topping

I mixed mentaiko, mayonnaise, and soy sauce.

I spread out the dough, added the mentaiko mayo, cheese, and corn, then baked it. Halfway through, I added thin slices of mochi (rice cake). After baking, I topped it with seaweed and the salmon terrine to finish!

Lots to reflect on

About the Terrine

In the video, you’ll see I divided the terrine into two portions. I was worried that the salmon and hanpen parts might end up looking too similar in color, making the “B” logo hard to see.

So for one half, I added ketchup, thinking: “Maybe this will make the red more vibrant?” But even with the ketchup, it didn’t change much.

The Mochi

I accidentally bought thinly sliced mochi, but I realized it might burn too easily as a pizza topping. Regular mochi with standard thickness is probably better.

I added the mochi halfway through baking, opening the oven once, but now I’m thinking that might have lowered the oven temp too much.

Lessons Learned

This was my first and only attempt—no test run beforehand— so I ended up with a long list of lessons learned. In the future, I should definitely do a trial version first… But you know… salmon and mentaiko are expensive! (excuses, excuses)

Cheese

I wanted to do that Instagram-worthy cheese pull moment, but nope. No stretch. None at all. I think that kind of thing needs a totally different kind of cheese or prep. Will have to experiment more.

Taste Test

Actually really good. I usually don’t eat mentaiko mayo myself, and I’m a Margherita pizza fan at heart. But this was surprisingly nice. A little rich in flavor—made me crave a bowl of rice. Next time, I might skip the soy sauce to tone it down a bit.

ビットコインピザデーということで ビットコインピザを作りました せっかくなので日本っぽい明太ピザにして ビットコインロゴは鮭のテリーヌにしました

鮭のテリーヌ

はんぺんでBのマークを気合で切ります 色付きクリアファイルをBマークに切って乗せると楽です 鮭とはんぺんと牛乳と卵と塩をフードプロセッサーにかけます 容器に流して蒸し焼きします

生地作り

強力粉・ドライイースト・塩・オリーブオイル・水を混ぜます 気合でこねます 1時間くらい発酵させるとふっくらします

トッピングの明太マヨ

明太子とマヨネーズとしょうゆを混ぜます

のばした生地に 明太マヨ・チーズ・コーンを乗せて焼きます 途中で薄いおもちを乗せます 焼けたらのりとテリーヌを乗せてできあがり

反省点いろいろ

今回一番くやしいのは明太マヨに色がつきすぎたこと 明太ピザってピンク色の感じが独特な気がするし もしかしたら日本だけかもと思ったから作ったのに 焼けたらトマトソースみたいな色になっちゃった なんてことだ 生地に焼き色がつかないな～白いな～もうちょっと焼くか～とか思ってたら 明太さんが焦げてました むねん

ちなみに製作動画の中でテリーヌを２つに分けているのは 鮭とはんぺんの部分が同じ色っぽくなってBが目立たなかったらどうしようと思って 片方はケチャップを足して 赤色濃くなるかな～大失敗したらいやだな～とか思ってたんですけど ケチャップ入れても何も変わらなかった むねん

薄いおもち（しゃぶしゃぶもちというらしい）を買ってしまったんだけど これはピザのトッピングにするには焦げそうだから 普通の厚みのもちの方がよさそう 今回は途中で一度オーブン開けておもちを乗せたけど オーブンの温度が下がるのが微妙かも

あと今回は練習無しのぶっつけ本番で作ったので ちょっと自分の中で反省点が多かったな～と やっぱり一度試作した方がいいですね いや鮭とか明太子とか高くて（言い訳

あ～あとチーズ 溶け溶けチーズがのびーるインスタ映え的なやつをやりたかったんですけど 全然むりでした のびないのびない ああいうのは別で工夫が必要そうなので要検討

味はおいしかったです 明太マヨって自分ではあんまり食べないしピザはマルゲリータ派なんですけど結構いいですね ちょっと味が濃くてご飯食べたくなっちゃった 次作る時はしょうゆ入れないようにしよう

Turning 60

Ten years ago, I turned 50 with a vague sense that something was off.

I was building things, but they didn’t feel grounded.\ I was "in tech," but tech felt like a treadmill—just faster, sleeker tools chasing the same hollow outcomes.\ I knew about Bitcoin, but I dismissed it. I thought it was just “tech for tech’s sake.”

Less than a year later, I fell down the rabbit hole.

It didn’t happen all at once. At first it was curiosity. Then dissonance. Then conviction.

Somewhere in that process, I realized Bitcoin wasn’t just financial—it was philosophical. It was moral. It was real. And it held up a mirror to a life I had built on momentum more than mission.

So I started pruning.

I left Web3.\ I pulled back from projects that ran on hype instead of honesty.\ I repented—for chasing relevance instead of righteousness.\ And I began stacking—not just sats, but new habits. New thinking. New rhythms of faith, work, and rest.

Now at 60, I’m not where I thought I’d be.

But I’m more myself than I’ve ever been.\ More convicted.\ More rooted.\ More ready.

Not to start over—but to build again, from the foundation up.

---

If you're in that middle place—between chapters, between convictions, between certainty and surrender—you're not alone.

🟠 I’m still here. Still building. Still listening.

Zap if this resonates, or send your story. I’d love to hear it.

n an inflationary system, the goal is often just to keep up.

With prices always rising, most of us are stuck in a race:\ Earn more to afford more.\ Spend before your money loses value.\ Monetize everything just to stay ahead of the curve.

Work becomes reactive.\ You hustle to outrun rising costs.\ You take on projects you don’t believe in just to make next month’s bills.\ Money decays. So you move faster, invest riskier, and burn out quicker.

But what happens when the curve flips?

A deflationary economy—like the one Bitcoin makes possible—rewards stillness, reflection, and intentionality.

Time favors the saver, not the spender.\ Money gains purchasing power.\ You’re no longer punished for patience.

You don’t have to convert your energy into cash before it loses value.\ You don’t have to be always on.\ You can actually afford to wait for the right work.

And when you do work—it means more.

💡 The “bullshit jobs” David Graeber wrote about start to disappear.\ There’s no need to look busy just to justify your existence.\ There’s no reward for parasitic middle layers.\ Instead, value flows to real craft, real care, and real proof of work—philosophically and literally.

So what does a job look like in that world?

— A farmer building soil instead of chasing subsidies.\ — An engineer optimizing for simplicity instead of speed.\ — A craftsman making one perfect table instead of ten cheap ones.\ — A writer telling the truth without clickbait.\ — A builder who says no more than they say yes.

You choose work that endures—not because it pays instantly, but because it’s worth doing.

The deflationary future isn’t a fantasy.\ It’s a recalibration.

It’s not about working less.\ It’s about working better.

That’s what Bitcoin taught me.\ That’s what I’m trying to live now.

The 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.

When a man meets a woman, they produce another human being.

The biological purpose of life is to reproduce, that's why we have reproductive organs.

However, you can't reproduce if you are dying of starvation or something else.

So you must look for food, shelter and other basic needs.

Once those needs are satisfied, the situation as a whole is more stable and then it is easier to reproduce.

Once another human being is created, you still must support him.

In the animal kingdom, human babies are the ones who take longer to walk and be independent as a whole.

Therefore, in the first years of our lives, we are very dependent on our parents or whoever is taking care of us.

We also have a biological drive for living.

That's why when someone is drowning he will hold on into whatever they can grab with the highest strength possible.

Or when our hand is close to fire or something hot, we remove our hand immediately from the hot thing, without thinking about removing our hand, we just do it.

These are just 2 examples, there are many other examples that show this biological tendency/reflex to keep ourselves alive.

We also have our brain, which we can use to get information/knowledge/ideas/advice from the ether.

In this sense, our brain is just an antenna or radio, and the ether is the signal.

Of course, we are not the radio, we are the signal.

In other words, you are not your body, you are pure consciousness "locked" temporarily in a body.

Because we can act after receiving information from the ether, we can construct and invent new things to make our lives easier.

So far, using only biology as our rule, we can get to the following conclusion: The purpose of life is to live in a safe place, work to get food and reproduce.

Because humans have been evolving in the technological sense, we don't need to hunt for food, we can just go to the market and buy meat.

And for the shelter(house), we just buy it.

Even though you can buy a house, it's still not yours, since the government or any thug can take it from you, but this is a topic for another article.

So, adjusting what I said before in a modern sense, the purpose of life is: Work in a normal job from Monday to Friday, save money, buy a house, buy a car, get a wife and have kids. Keep working until you are old enough, then retire and do nothing for the rest of your life, just waiting for the moment you die.

Happy life, happy ending, right?

No.

There is something else to it, there is another side of the coin.

This is explored briefly by Steve Jobs in this video, but I pretend to go much further than him: https://youtu.be/uf6TzOHO_dk

Let's get to the point now.

First of all, you are alive. This is not normal.

Don't take life for granted.

There is no such a thing as a coincidence. Chance is but a name given for a law that has not been recognized yet.

You are here for a reason.

God is real. All creation starts in the mind.

The mind is the source of all creation.

When the mind of god starts thinking, it records its thoughts into matter through light.

But this is too abstract, let's get to something simple.

Governments exist, correct?

The force behind thinking is desire, without desire there is no creation.

If desired ceased to exist, everything would just vanish in the blink of an eye.

How governments are supported financially?

By taking your money.

Which means, you produce, and they take it.

And you can't go against it without suffering, therefore, you are a slave.

Are you realizing the gravity of the situation?

You are working to keep yourself alive as well as faceless useless men that you don't even know.

Your car must have an identification.

When you are born, you must have an identification.

In brazil, you can't home school your children.

When "your" "country" is in war, you must fight to defend it and give your life.

Countries are limited by imaginary lines.

How many lives have been destroyed in meaningless wars?

You must go to the front-line to defend your masters.

In most countries, you don't have freedom of speech, which means, you can't even express what you think.

When you create a company, you must have an identification and pass through a very bureaucratic process.

The money you use is just imaginary numbers in the screen of a computer or phone.

The money you use is created out of thin air.

By money here, I am referring to fiat money, not bitcoin.

Bitcoin is an alternative to achieve freedom, but this is topic for another article.

Depending on what you want to work on, you must go to college.

If you want to become a doctor, you must spend at least 5 years in an university decorating useless muscle names and bones.

Wisdom is way more important than knowledge.

That's why medical errors are the third leading cause of death in United States of America.

And I'm not even talking about Big Pharma and the "World Health Organization"

You can't even use or sell drugs, your masters don't allow it.

All the money you get, you must explain from where you got it.

Meanwhile, your masters have "black budget" and don't need to explain anything to you, even though everything they do is financed by your money.

In most countries you can't buy a gun, while your masters have a whole army fully armed to the teeth to defend them.

Your masters want to keep you sedated and asleep.

Look at all the "modern" art produced nowadays.

Look at the media, which of course was never created to "inform you".

Your masters even use your body to test their bio-technology, as happened with the covid 19 vaccines.

This is public human testing, there's of course secretive human testing, such as MKUltra and current experiments that happen nowadays that I don't even know.

I can give hundreds of millions of examples, quite literally, but let's just focus in one case, Jeffrey Epstein.

He was a guy who got rich "suddenly" and used his influence and spy skills to blackmail politicians and celebrities through recording them doing acts of pedophilia.

In United States of America, close to one million children a year go missing every year.

Some portion of these children are used in satanic rituals, and the participants of these rituals are individuals from the "high society".

Jeffrey Epstein was just an "employee", he was not the one at the top of the evil hierarchy.

He was serving someone or a group of people that I don't know who they are.

That's why they murdered him.

Why am I saying all of this?

The average person who sleep, work, eat and repeat has no idea all of this is going on.

They have no idea there is a very small group of powerful people who are responsible for many evil damage in the world.

They think the world is resumed in their little routine.

They think their routine is all there is to it.

They don't know how big the world truly is, in both a good and evil sense.

Given how much we produce and all the technology we have, people shouldn't even have to work, things would be almost nearly free.

Why aren't they?

Because of taxes.

This group of people even has access to a free energy device, which would disrupt the world in a magnitude greater than everything we have ever seen in the history of Earth.

That's why MANY people who tried to work in any manifestation of a free energy device have been murdered, or rather, "fell from a window".

How do I know a free energy device exist? This is topic for another article.

So my conclusion is:

We are in hell already. Know thyself. Use your mind for creation, any sort of creation. Do good for the people around you and the people you meet, always give more than you get, try to do your best in everything you set out to do, even if it's a boring or mundane work.

Life is short.

Our body can live no longer than 300 years.

Most people die before 90.

Know thyself, do good to the world while you can.

Wake up!!! Stop being sedated and asleep.

Be conscious.

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 .

如果比特币发明了真正的钱，那么 Crypto 是什么？

引言

比特币诞生之初就以“数字黄金”姿态示人，被支持者誉为人类历史上第一次发明了真正意义上的钱——一种不依赖国家信用、总量恒定且不可篡改的硬通货。然而十多年过去，比特币之后蓬勃而起的加密世界（Crypto）已经远超“货币”范畴：从智能合约平台到去中心组织，从去央行的稳定币到戏谑荒诞的迷因币，Crypto 演化出一个丰富而混沌的新生态。这不禁引发一个根本性的追问：如果说比特币解决了“真金白银”的问题，那么 Crypto 又完成了什么发明？

Crypto 与政治的碰撞：随着Crypto版图扩张，全球政治势力也被裹挟进这场金融变革洪流（示意图）。比特币的出现重塑了货币信用，但Crypto所引发的却是一场更深刻的政治与治理结构实验。从华尔街到华盛顿，从散户论坛到主权国家，越来越多人意识到：Crypto不只是技术或金融现象，而是一种全新的政治表达结构正在萌芽。正如有激进论者所断言的：“比特币发明了真正的钱，而Crypto则在发明新的政治。”价格K线与流动性曲线，或许正成为这个时代社群意志和社会价值观的新型投射。

冲突结构：当价格挑战选票

传统政治中，选票是人民意志的载体，一人一票勾勒出民主治理的正统路径。而在链上的加密世界里，骤升骤降的价格曲线和真金白银的买卖行为却扮演起了选票的角色：资金流向成了民意走向，市场多空成为立场表决。价格行为取代选票，这听来匪夷所思，却已在Crypto社群中成为日常现实。每一次代币的抛售与追高，都是社区对项目决策的即时“投票”；每一根K线的涨跌，都折射出社区意志的赞同或抗议。市场行为本身承担了决策权与象征权——价格即政治，正在链上蔓延。

这一新生政治形式与旧世界的民主机制形成了鲜明冲突。bitcoin.org中本聪在比特币白皮书中提出“一CPU一票”的工作量证明共识，用算力投票取代了人为决策bitcoin.org。而今，Crypto更进一步，用资本市场的涨跌来取代传统政治的选举。支持某项目？直接购入其代币推高市值；反对某提案？用脚投票抛售资产。相比漫长的选举周期和层层代议制，链上市场提供了近乎实时的“公投”机制。但这种机制也引发巨大争议：资本的投票天然偏向持币多者（富者）的意志，是否意味着加密政治更为金权而非民权？持币多寡成为影响力大小，仿佛选举演变成了“一币一票”，巨鲸富豪俨然掌握更多话语权。这种与民主平等原则的冲突，成为Crypto政治形式饱受质疑的核心张力之一。

尽管如此，我们已经目睹市场投票在Crypto世界塑造秩序的威力：2016年以太坊因DAO事件分叉时，社区以真金白银“投票”决定了哪条链获得未来。arkhamintelligence.com结果是新链以太坊（ETH）成为主流，其市值一度超过2,800亿美元，而坚持原则的以太经典（ETC）市值不足35亿美元，不及前者的八十分之一arkhamintelligence.com。市场选择清楚地昭示了社区的政治意志。同样地，在比特币扩容之争、各类硬分叉博弈中，无不是由投资者和矿工用资金与算力投票，胜者存续败者黯然。价格成为裁决纷争的最终选票，冲击着传统“选票决胜”的政治理念。Crypto的价格民主，与现代代议民主正面相撞，激起当代政治哲思中前所未有的冲突火花。

治理与分配

XRP对决SEC成为了加密世界“治理与分配”冲突的经典战例。2020年底，美国证券交易委员会（SEC）突然起诉Ripple公司，指控其发行的XRP代币属于未注册证券，消息一出直接引爆市场恐慌。XRP价格应声暴跌，一度跌去超过60%，最低触及0.21美元coindesk.com。曾经位居市值前三的XRP险些被打入谷底，监管的强硬姿态似乎要将这个项目彻底扼杀。

然而XRP社区没有选择沉默。 大批长期持有者组成了自称“XRP军团”（XRP Army）的草根力量，在社交媒体上高调声援Ripple，对抗监管威胁。面对SEC的指控，他们集体发声，质疑政府选择性执法，声称以太坊当年发行却“逍遥法外”，只有Ripple遭到不公对待coindesk.com。正如《福布斯》的评论所言：没人预料到愤怒的加密散户投资者会掀起法律、政治和社交媒体领域的‘海啸式’反击，痛斥监管机构背弃了保护投资者的承诺crypto-law.us。这种草根抵抗监管的话语体系迅速形成：XRP持有者不但在网上掀起舆论风暴，还采取实际行动向SEC施压。他们发起了请愿，抨击SEC背离保护投资者初衷、诉讼给个人投资者带来巨大伤害，号召停止对Ripple的上诉纠缠——号称这是在捍卫全球加密用户的共同利益bitget.com。一场由民间主导的反监管运动就此拉开帷幕。

Ripple公司则选择背水一战，拒绝和解，在法庭上与SEC针锋相对地鏖战了近三年之久。Ripple坚称XRP并非证券，不应受到SEC管辖，即使面临沉重法律费用和业务压力也不妥协。2023年，这场持久战迎来了标志性转折：美国法庭作出初步裁决，认定XRP在二级市场的流通不构成证券coindesk.com。这一胜利犹如给沉寂已久的XRP注入强心针——消息公布当天XRP价格飙涨近一倍，盘中一度逼近1美元大关coindesk.com。沉重监管阴影下苟延残喘的项目，凭借司法层面的突破瞬间重获生机。这不仅是Ripple的胜利，更被支持者视为整个加密行业对SEC强权的一次胜仗。

XRP的对抗路线与某些“主动合规”的项目形成了鲜明对比。 稳定币USDC的发行方Circle、美国最大合规交易所Coinbase等选择了一条迎合监管的道路：它们高调拥抱现行法规，希望以合作换取生存空间。然而现实却给了它们沉重一击。USDC稳定币在监管风波中一度失去美元锚定，哪怕Circle及时披露储备状况也无法阻止恐慌蔓延，大批用户迅速失去信心，短时间内出现数十亿美元的赎回潮blockworks.co。Coinbase则更为直接：即便它早已注册上市、反复向监管示好，2023年仍被SEC指控为未注册证券交易所reuters.com，卷入漫长诉讼漩涡。可见，在迎合监管的策略下，这些机构非但未能换来监管青睐，反而因官司缠身或用户流失而丧失市场信任。 相比之下，XRP以对抗求生存的路线反而赢得了投资者的眼光：价格的涨跌成为社区投票的方式，抗争的勇气反过来强化了市场对它的信心。

同样引人深思的是另一种迥异的治理路径：技术至上的链上治理。 以MakerDAO为代表的去中心化治理模式曾被寄予厚望——MKR持币者投票决策、算法维持稳定币Dai的价值，被视为“代码即法律”的典范。然而，这套纯技术治理在市场层面却未能形成广泛认同，亦无法激发群体性的情绪动员。复杂晦涩的机制使得普通投资者难以参与其中，MakerDAO的治理讨论更多停留在极客圈子内部，在社会大众的政治对话中几乎听不见它的声音。相比XRP对抗监管所激发的铺天盖地关注，MakerDAO的治理实验显得默默无闻、难以“出圈”。这也说明，如果一种治理实践无法连接更广泛的利益诉求和情感共鸣，它在社会政治层面就难以形成影响力。

XRP之争的政治象征意义由此凸显： 它展示了一条“以市场对抗国家”的斗争路线，即通过代币价格的集体行动来回应监管权力的施压。在这场轰动业界的对决中，价格即是抗议的旗帜，涨跌映射着政治立场。XRP对SEC的胜利被视作加密世界向旧有权力宣告的一次胜利：资本市场的投票器可以撼动监管者的强权。这种“价格即政治”的张力，正是Crypto世界前所未有的社会实验：去中心化社区以市场行为直接对抗国家权力，在无形的价格曲线中凝聚起政治抗争的力量，向世人昭示加密货币不仅有技术和资本属性，更蕴含着不可小觑的社会能量和政治意涵。

不可归零的政治资本

Meme 币的本质并非廉价或易造，而在于其构建了一种“无法归零”的社群生存结构。 对于传统观点而言，多数 meme 币只是短命的投机游戏：价格暴涨暴跌后一地鸡毛，创始人套现跑路，投资者血本无归，然后“大家转去炒下一个”theguardian.com。然而，meme 币社群的独特之处在于——失败并不意味着终结，而更像是运动的逗号而非句号。一次币值崩盘后，持币的草根们往往并未散去；相反，他们汲取教训，准备东山再起。这种近乎“不死鸟”的循环，使得 meme 币运动呈现出一种数字政治循环的特质：价格可以归零，但社群的政治热情和组织势能不归零。正如研究者所指出的，加密领域中的骗局、崩盘等冲击并不会摧毁生态，反而成为让系统更加强韧的“健康应激”，令整个行业在动荡中变得更加反脆弱cointelegraph.com。对应到 meme 币，每一次暴跌和重挫，都是社群自我进化、卷土重来的契机。这个去中心化群体打造出一种自组织的安全垫，失败者得以在瓦砾上重建家园。对于草根社群、少数派乃至体制的“失败者”而言，meme 币提供了一个永不落幕的抗争舞台，一种真正反脆弱的政治性。正因如此，我们看到诸多曾被嘲笑的迷因项目屡败屡战：例如 Dogecoin 自2013年问世后历经八年沉浮，早已超越玩笑属性，成为互联网史上最具韧性的迷因之一frontiersin.org；支撑 Dogecoin 的正是背后强大的迷因文化和社区意志，它如同美国霸权支撑美元一样，为狗狗币提供了“永不中断”的生命力frontiersin.org。

“复活权”的数字政治意涵

这种“失败-重生”的循环结构蕴含着深刻的政治意涵：在传统政治和商业领域，一个政党选举失利或一家公司破产往往意味着清零出局，资源散尽、组织瓦解。然而在 meme 币的世界，社群拥有了一种前所未有的“复活权”。当项目崩盘，社区并不必然随之消亡，而是可以凭借剩余的人心和热情卷土重来——哪怕换一个 token 名称，哪怕重启一条链，运动依然延续。正如 Cheems 项目的核心开发者所言，在几乎无人问津、技术受阻的困境下，大多数人可能早已卷款走人，但 “CHEEMS 社区没有放弃，背景、技术、风投都不重要，重要的是永不言弃的精神”cointelegraph.com。这种精神使得Cheems项目起死回生，社区成员齐声宣告“我们都是 CHEEMS”，共同书写历史cointelegraph.com。与传统依赖风投和公司输血的项目不同，Cheems 完全依靠社区的信念与韧性存续发展，体现了去中心化运动的真谛cointelegraph.com。这意味着政治参与的门槛被大大降低：哪怕没有金主和官方背书，草根也能凭借群体意志赋予某个代币新的生命。对于身处社会边缘的群体来说，meme 币俨然成为自组织的安全垫和重新集结的工具。难怪有学者指出，近期涌入meme币浪潮的主力，正是那些对现实失望但渴望改变命运的年轻人theguardian.com——“迷茫的年轻人，想要一夜暴富”theguardian.com。meme币的炒作表面上看是投机赌博，但背后蕴含的是草根对既有金融秩序的不满与反抗：没有监管和护栏又如何？一次失败算不得什么，社区自有后路和新方案。这种由底层群众不断试错、纠错并重启的过程，本身就是一种数字时代的新型反抗运动和群众动员机制。

举例而言，Terra Luna 的沉浮充分展现了这种“复活机制”的政治力量。作为一度由风投资本热捧的项目，Luna 币在2022年的崩溃本可被视作“归零”的失败典范——稳定币UST瞬间失锚，Luna币价归零，数十亿美元灰飞烟灭。然而“崩盘”并没有画下休止符。Luna的残余社区拒绝承认失败命运，通过链上治理投票毅然启动新链，“复活”了 Luna 代币，再次回到市场交易reuters.com。正如 Terra 官方在崩盘后发布的推文所宣称：“我们力量永在社区，今日的决定正彰显了我们的韧性”reuters.com。事实上，原链更名为 Luna Classic 后，大批所谓“LUNC 军团”的散户依然死守阵地，誓言不离不弃；他们自发烧毁巨量代币以缩减供应、推动技术升级，试图让这个一度归零的项目重新燃起生命之火binance.com。失败者并未散场，而是化作一股草根洪流，奋力托举起项目的残迹。经过迷因化的叙事重塑，这场从废墟中重建价值的壮举，成为加密世界中草根政治的经典一幕。类似的案例不胜枚举：曾经被视为笑话的 DOGE（狗狗币）正因多年社群的凝聚而跻身主流币种，总市值一度高达数百亿美元，充分证明了“民有民享”的迷因货币同样可以笑傲市场frontiersin.org。再看最新的美国政治舞台，连总统特朗普也推出了自己的 meme 币 $TRUMP，号召粉丝拿真金白银来表达支持。该币首日即从7美元暴涨至75美元，两天后虽回落到40美元左右，但几乎同时，第一夫人 Melania 又发布了自己的 $Melania 币，甚至连就职典礼的牧师都跟风发行了纪念币theguardian.com！显然，对于狂热的群众来说，一个币的沉浮并非终点，而更像是运动的换挡——资本市场成为政治参与的新前线，你方唱罢我登场，meme 币的群众动员热度丝毫不减。值得注意的是，2024年出现的 Pump.fun 等平台更是进一步降低了这一循环的技术门槛，任何人都可以一键生成自己的 meme 币theguardian.com。这意味着哪怕某个项目归零，剩余的社区完全可以借助此类工具迅速复制一个新币接力，延续集体行动的火种。可以说，在 meme 币的世界里，草根社群获得了前所未有的再生能力和主动权，这正是一种数字时代的群众政治奇观：失败可以被当作梗来玩，破产能够变成重生的序章。

价格即政治：群众投机的新抗争

meme 币现象的兴盛表明：在加密时代，价格本身已成为一种政治表达。这些看似荒诞的迷因代币，将金融市场变成了群众宣泄情绪和诉求的另一个舞台。有学者将此概括为“将公民参与直接转化为了投机资产”cdn-brighterworld.humanities.mcmaster.ca——也就是说，社会运动的热情被注入币价涨跌，政治支持被铸造成可以交易的代币。meme 币融合了金融、技术与政治，通过病毒般的迷因文化激发公众参与，形成对现实政治的某种映射cdn-brighterworld.humanities.mcmaster.caosl.com。当一群草根投入全部热忱去炒作一枚毫无基本面支撑的币时，这本身就是一种大众政治动员的体现：币价暴涨，意味着一群人以戏谑的方式在向既有权威叫板；币价崩盘，也并不意味着信念的消亡，反而可能孕育下一次更汹涌的造势。正如有分析指出，政治类 meme 币的出现前所未有地将群众文化与政治情绪融入市场行情，价格曲线俨然成为民意和趋势的风向标cdn-brighterworld.humanities.mcmaster.ca。在这种局面下，投机不再仅仅是逐利，还是一种宣示立场、凝聚共识的过程——一次次看似荒唐的炒作背后，是草根对传统体制的不服与嘲讽，是失败者拒绝认输的呐喊。归根结底，meme 币所累积的，正是一种不可被归零的政治资本。价格涨落之间，群众的愤怒、幽默与希望尽显其中；这股力量不因一次挫败而消散，反而在市场的循环中愈发壮大。也正因如此，我们才说“价格即政治”——在迷因币的世界里，价格不只是数字，更是人民政治能量的晴雨表，哪怕归零也终将卷土重来。cdn-brighterworld.humanities.mcmaster.caosl.com

全球新兴现象：伊斯兰金融的入场

当Crypto在西方世界掀起市场治政的狂潮时，另一股独特力量也悄然融入这一场域：伊斯兰金融携其独特的道德秩序，开始在链上寻找存在感。长期以来，伊斯兰金融遵循着一套区别于世俗资本主义的原则：禁止利息（Riba）、反对过度投机（Gharar/Maysir）、强调实际资产支撑和道德投资。当这些原则遇上去中心化的加密技术，会碰撞出怎样的火花？出人意料的是，这两者竟在“以市场行为表达价值”这个层面产生了惊人的共鸣。伊斯兰金融并不拒绝市场机制本身，只是为其附加了道德准则；Crypto则将市场机制推向了政治高位，用价格来表达社群意志。二者看似理念迥异，实则都承认市场行为可以也应当承载社会价值观。这使得越来越多金融与政治分析人士开始关注：当虔诚的宗教伦理遇上狂野的加密市场，会塑造出何种新范式？

事实上，穆斯林世界已经在探索“清真加密”的道路。一些区块链项目致力于确保协议符合伊斯兰教法（Sharia）的要求。例如Haqq区块链发行的伊斯兰币（ISLM），从规则层面内置了宗教慈善义务——每发行新币即自动将10%拨入慈善DAO，用于公益捐赠，以符合天课（Zakat）的教义nasdaq.comnasdaq.com。同时，该链拒绝利息和赌博类应用，2022年还获得了宗教权威的教令（Fatwa）认可其合规性nasdaq.com。再看理念层面，伊斯兰经济学强调货币必须有内在价值、收益应来自真实劳动而非纯利息剥削。这一点与比特币的“工作量证明”精神不谋而合——有人甚至断言法定货币无锚印钞并不清真，而比特币这类需耗费能源生产的资产反而更符合教法初衷cointelegraph.com。由此，越来越多穆斯林投资者开始以道德投资的名义进入Crypto领域，将资金投向符合清真原则的代币和协议。

这种现象带来了微妙的双重合法性：一方面，Crypto世界原本奉行“价格即真理”的世俗逻辑，而伊斯兰金融为其注入了一股道德合法性，使部分加密资产同时获得了宗教与市场的双重背书；另一方面，即便在遵循宗教伦理的项目中，最终决定成败的依然是市场对其价值的认可。道德共识与市场共识在链上交汇，共同塑造出一种混合的新秩序。这一全球新兴现象引发广泛议论：有人将其视为金融民主化的极致表现——不同文化价值都能在市场平台上表达并竞争；也有人警惕这可能掩盖新的风险，因为把宗教情感融入高风险资产，既可能凝聚强大的忠诚度，也可能在泡沫破裂时引发信仰与财富的双重危机。但无论如何，伊斯兰金融的入场使Crypto的政治版图更加丰盈多元。从华尔街交易员到中东教士，不同背景的人们正通过Crypto这个奇特的舞台，对人类价值的表达方式进行前所未有的实验。

升华结语：价格即政治的新直觉

回顾比特币问世以来的这段历程，我们可以清晰地看到一条演进的主线：先有货币革命，后有政治发明。比特币赋予了人类一种真正自主的数字货币，而Crypto在此基础上完成的，则是一项前所未有的政治革新——它让市场价格行为承担起了类似政治选票的功能，开创了一种“价格即政治”的新直觉。在这个直觉下，市场不再只是冷冰冰的交易场所；每一次资本流动、每一轮行情涨落，都被赋予了社会意义和政治涵义。买入即表态，卖出即抗议，流动性的涌入或枯竭胜过千言万语的陈情。Crypto世界中，K线图俨然成为民意曲线，行情图就是政治晴雨表。决策不再由少数权力精英关起门来制定，而是在全球无眠的交易中由无数普通人共同谱写。这样的政治形式也许狂野，也许充满泡沫和噪音，但它不可否认地调动起了广泛的社会参与，让原本疏离政治进程的个体通过持币、交易重新找回了影响力的幻觉或实感。

“价格即政治”并非一句简单的口号，而是Crypto给予世界的全新想象力。它质疑了传统政治的正统性：如果一串代码和一群匿名投资者就能高效决策资源分配，我们为何还需要繁冗的官僚体系？它也拷问着自身的内在隐忧：当财富与权力深度绑定，Crypto政治如何避免堕入金钱统治的老路？或许，正是在这样的矛盾和张力中，人类政治的未来才会不断演化。Crypto所开启的，不仅是技术乌托邦或金融狂欢，更可能是一次对民主形式的深刻拓展和挑战。这里有最狂热的逐利者，也有最理想主义的社群塑梦者；有一夜暴富的神话，也有瞬间破灭的惨痛。而这一切汇聚成的洪流，正冲撞着工业时代以来既定的权力谱系。

当我们再次追问：Crypto究竟是什么？ 或许可以这样回答——Crypto是比特币之后，人类完成的一次政治范式的试验性跃迁。在这里，价格行为化身为选票，资本市场演化为广场，代码与共识共同撰写“社会契约”。这是一场仍在进行的文明实验：它可能无声地融入既有秩序，也可能剧烈地重塑未来规则。但无论结局如何，如今我们已经见证：在比特币发明真正的货币之后，Crypto正在发明真正属于21世纪的政治。它以数字时代的语言宣告：在链上，价格即政治，市场即民意，代码即法律。这，或许就是Crypto带给我们的最直观而震撼的本质启示。

@ c066aac5:6a41a034

I’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.

Introduction

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.

• The tools for liberation already exist.

• The question is: will we use them?

Yeah, I’m sure everything in the file is legit. 👍 Let’s review the guard witness testimony…Oh wait, they weren’t at their posts despite 24/7 survellience instructions after another Epstein “suicide” attempt two weeks earlier. Well, at least the video of the suicide is in the file? Oh wait, a techical glitch. Damn those coincidences!

At this point, the Trump administration has zero credibility with me on anything related to the Epstein case and his clients. I still suspect the administration is using the Epstein files as leverage to keep a lot of RINOs in line, whereas they’d be sabotaging his agenda at every turn otherwise. However, I just don’t believe in ends-justify-the-means thinking. It’s led almost all of DC to toss out every bit of the values they might once have had.

BCL2 took place today. I drew the third pick.

Here are the results:

1.3 Ja’Marr Chase — I didn’t want Christian McCalfinjury, of whom I already have a share, so I was set on CeeDee Lamb or Tyreek Hill if they were there. But I had an inkling they might go 1-2 in which case Ja’Marr Chase was narrowly my fallback over Amon Ra St. Brown and Breece Hall. Chase has St. Brown’s target upside, but with a much bigger vertical game. The biggest negative for him is Burrow’s health, but Burrow’s fine now, and anyone can get hurt. I also thought maybe I’d draft Tee Higgins if he fell to me in Round 5 (which was unlikely) in which case I’d try to get Burrow too.

2.10 Jaylen Waddle — It was Waddle the solid, boring pick or Malik Nabers the fun, exciting one. Team 4 did me a favor and took De’Von Achane out of the equation — I have Achane in BCL1, and while I love his upside, he’s not the kind of player to which you tie all your teams. I narrowly went Waddle who actually has upside too if Tyreek Hill ever got hurt.

3.10 Malik Nabers — I couldn’t believe it, but Nabers made it all the way back despite third-round reversal. I love Nabers, but I think the market is over-drafting him slightly relative to his projected target share. I mean he might get 150, but I think 130-140 Daniel Jones targets is more likely, and that’s a third, not a second-round pick. ** 4.3 Stefon Diggs** — This was going perfectly. Had Nabers been taken, I would have gone Diggs in Round 3, but he was still there four picks later. I’ve mentioned before I have Diggs as a top-10-ish WR.

5.10 Anthony Richardson — I took Reachardson early because I didn’t need another receiver (would be my first bench spot), the running back I liked best was still likely to be back in Round 6 too, and I couldn’t bring myself to take Kyle Pitts who has burned me so many times. ** 6.3 Rhamondre Stevenson** — Backs were flying off the board in this draft which figures because I went so WR-heavy, but I think Stevenson is good, and there’s no way the Patriots offense won’t be better than last year’s just from pure regression to the mean.

7.10 Javonte Williams — Another good back on a bad team, Williams’ 2023 was not representative given he was only one year removed from an ACL tear. We should see the real version this year, and I expect him to be the main guy in Denver. ** 8.3 Ladd McConkey** — This was a luxury pick, but I liked the value too much, and I wasn’t in love with any of the RB or TE at cost. (I missed out on Jake Ferguson right after the Williams pick.) But the McConkey pick cost me Zack Moss, Devin Singletary, Nick Chubb, Brian Robinson, Chase Brown, Blake Corum and Tyjae Spears.

9.10 Brock Bowers — I missed out on David Njoku by one pick too, so it was time to get Bowers, the last of that tier of tight ends.

10.3 Jerome Ford — He’s Nick Chubb’s backup at worst, and that assumes Chubb will even be at full health any time soon.

11.10 Rashid Shaheed — Another luxury pick, but I couldn’t pass him up here. I’ve mentioned many times, I think he’s as good as Chris Olave, and there are only two of them now, so Shaheed should see his share of targets, either way. Shaheed cost me Zach Charbonnet and Cole Kmet though.

12.3 J.K. Dobbins — I’m not a big Gus Edwards believer — he’s 29 and with a limited skill set. Dobbins can never stay healthy, but worth a flyer here on what should be a run-heavy offense.

13.10 Kimani Vidal — Sounds like a high-end hair salon, but he’s actually the fallback if Dobbins and Edwards don’t pan out. I like his build (5-8, 215), speed and pass-catching skills.

14.3 Bucky Irving — I’m not sold on Rachaad White being anything special, and Irving is his backup. I needed a lot of lottery ticket backs with this build. ** 15.10 Khalil Herbert** — There are rumors he could be moved, but either way, I don’t trust D’Andre Soft, and Roschon Johnson is just a guy.

16.3 Jonnu Smith — This was a bit early per ADP, but I needed a second TE, and Smith has a lot of upside in an offense that’s so top heavy.

17.10 Justin Fields — In the likely event Russell Wilson is cooked, Fields is a top-10 fantasy quarterback already. I thought about Danny Dimes too. ** 18.3 Younghoe Koo** — I’m tired of drafting Justin Tucker every year, felt it was time for a Younghoe.

19.10 Giants Defense — They get the Sam Darnold Vikings in Week 1, the Football Team in Week 2. And they now have three elite pass rushers in Kayvon Thibodeaux, Dexter Lawrence and Brian Burns.

20.3 Roman Wilson — I wanted to take Danny Dimes, but Wilson could easily be the Steelers’ slot guy — Van Jefferson is bad, and even George Pickens is more of a highlight-reel guy who doesn’t command massive target share.

บางครั้งพลังยิ่งใหญ่ที่สุดก็ไม่ใช่สิ่งที่เห็นได้ด้วยตาเปล่า เหมือนแสงแดดที่คนส่วนใหญ่มักจะกลัวเพราะกลัวผิวเสีย กลัวฝ้า กลัวร้อน แต่แท้จริงแล้วในแสงแดดมีบางสิ่งที่น่าเคารพอยู่ลึกๆ มันคือแสงที่มองไม่เห็น มันไม่แสบตา ไม่แสบผิว แต่มันลึก ถึงเซลล์ มันคือ “แสงอินฟราเรด” ที่ซ่อนตัวอย่างสุภาพในแดดยามเช้า

เฮียมักชอบพูดว่า แดดที่ดีไม่จำเป็นต้องแสบหลัง อาบแสงที่ลอดผ่านใบไม้ยามเช้าแบบไม่ต้องฝืนตาก็พอ แสงอินฟราเรดนี่แหละคือพระเอกตัวจริงในความเงียบ มันไม่ดัง ไม่โชว์ ไม่โฆษณา แต่มันลงลึกไปถึงระดับที่ร่างกายเรากำลังหิวโดยไม่รู้ตัวในระดับเซลล์

ในเซลล์ของเรา มีหน่วยผลิตพลังงานที่เรียกว่าไมโทคอนเดรีย เจ้านี่แหละคือโรงไฟฟ้าจิ๋วประจำบ้าน ที่ต้องตื่นมาทำงานทุกวันโดยไม่ได้หยุดเสาร์อาทิตย์ ยิ่งถ้าไมโทคอนเดรียทำงานไม่ดี ร่างกายก็จะเหมือนไฟตกทั้งระบบ—ง่วงง่าย เพลียไว ปวดนู่นปวดนี่เหมือนไฟในบ้านกระพริบตลอดเวลา

แล้วแสงอินฟราเรดเกี่ยวอะไรกับมัน? เฮียขอเล่าง่ายๆ ว่า ไมโทคอนเดรียมีตัวรับแสงตัวหนึ่งชื่อว่า cytochrome c oxidase เจ้านี่ตอบสนองต่อแสงอินฟราเรดช่วงคลื่นเฉพาะ คือประมาณ 600–900 นาโนเมตร พอโดนเข้าไป มันเหมือนได้จุดประกายให้โรงงานพลังงานในร่างกายกลับมาคึกคักอีกครั้ง ผลิตพลังงานได้มากขึ้น ระบบไหลเวียนเลือดก็ดีขึ้น เหมือนท่อน้ำที่เคยอุดตันก็กลับมาใสแจ๋ว ความอักเสบเล็กๆ ในร่างกายก็ลดลง คล้ายบ้านที่เคยอับชื้นแล้วได้เปิดหน้าต่างให้แสงแดดส่องเข้าไป

และที่น่ารักกว่านั้นคือ เราไม่ต้องไปถึงชายหาด ไม่ต้องจองรีสอร์ตริมทะเล แค่แดดเช้าอ่อนๆ ข้างบ้านหรือตามขอบระเบียง ก็ให้แสงอินฟราเรดได้แล้ว ถ้าใครอยู่ในเมืองใหญ่ที่มีแต่ตึกบังแดด แล้วจะเลือกใช้หลอดไฟ Red Light Therapy ก็ไม่ผิด แต่ต้องเลือกแบบรู้เท่าทันรู้ ไม่ใช่เห็นใครรีวิวก็ซื้อมาเปิดใส่หน้า หวังจะหน้าใสข้ามคืน ต้องเข้าใจทั้งความยาวคลื่น เวลาใช้งาน และจุดประสงค์ ไม่ใช่ใช้เพราะแค่กลัวแก่อยากหน้าตึง แต่ใช้เพราะอยากให้ร่างกายกลับไปทำงานอย่างเป็นธรรมชาติอีกครั้ง และอยู่ในประเทศหรือสถานที่ที่โดนแดดได้น้อยอยากได้เสริมเฉยๆ

แล้วเราจะรู้ได้ยังไงว่าไมโทคอนเดรียเรากลับมาทำงานดีขึ้น? เฮียว่าไม่ต้องรอผลเลือดจากแล็บไหนก็รู้ได้ อย่าไปยึดติดกับตัวเลขมากครับ เอาตัวเองเป็นหลัก ตั้งคำถามกับตัวเองว่ารู้สึกยังไงบ้าง ถ้าเริ่มนอนหลับลึกขึ้น ตื่นมาแล้วหัวไม่มึน ไม่หงุดหงิดตั้งแต่ยังไม่ลืมตา ถ้าปวดหลังปวดข้อที่เคยมีเริ่มหายไปแบบไม่ได้กินยา หรือแม้แต่ผิวที่ดูสดใสขึ้นแบบไม่ต้องง้อสกินแคร์ นั่นแหละคือเสียงขอบคุณเบาๆ จากไมโทคอนเดรียที่ได้แสงแดดแล้วกลับมามีชีวิตอีกครั้ง ถ้ามันดีก็คือดี

บางที เราไม่ต้องกินวิตามินเม็ดไหนเพิ่ม แค่เดินออกไปรับแดดเบาๆ ในเวลาเช้าๆ แล้วให้ร่างกายได้พูดคุยกับธรรมชาติบ้าง เพราะในความอบอุ่นเงียบๆ ของแสงอินฟราเรดนั้น มีเสียงเบาๆ ที่กำลังปลุกพลังในตัวเราให้กลับมาอีกครั้ง

แดดไม่ใช่ศัตรู ถ้าเรารู้จักมันในมุมที่ถูกต้อง เฮียแค่อยากชวนให้ลองเปลี่ยนจากคำว่า “กลัวแดด” เป็น “ฟังแดด” เพราะบางครั้งธรรมชาติไม่ได้พูดด้วยคำ แต่สื่อสารด้วยแสงที่แทรกผ่านหัวใจเราโดยไม่ต้องผ่านล่าม

บางคนอาจคิดในใจ “แหมเฮีย ก็ดีหรอก ถ้าได้ตื่นเช้า” 555555

เฮียเข้าใจดีเลยว่าไม่ใช่ทุกคนจะตื่นมาทันแดดยามเช้าได้เสมอไป ชีวิตคนเรามันไม่ได้เริ่มต้นพร้อมไก่ขันทุกวัน บางคนเพิ่งเข้านอนตอนตีสาม ตื่นอีกทีแดดก็แตะบ่ายเข้าไปแล้ว ไม่ต้องกังวลไปจ้ะ เพราะความมหัศจรรย์ของแสงอินฟราเรดยังมีให้เราได้ใช้แม้ในแดดยามเย็น

แดดช่วงเย็น โดยเฉพาะหลังสี่โมงเย็นไปจนเกือบหกโมง (หรือเร็วช้าตามฤดู) ก็ยังอุดมไปด้วยแสงอินฟราเรดในช่วงคลื่นที่ไมโทคอนเดรียชอบ แถมยังไม่มีรังสี UV ที่แรงจัดมารบกวนเหมือนตอนเที่ยง เรียกว่าเป็นแดดแบบละมุนๆ สำหรับคนที่อยาก “บำบัดใจ” แบบไม่ต้องร้อนจนหัวเปียก

เฮียเคยลองตากแดดเย็นเดินไปในสวนสาธารณะ แล้วรู้สึกว่ามันเหมือนได้รีเซ็ตจิตใจหลังวันเหนื่อยๆ ไปในตัว ยิ่งพอรู้ว่าในช่วงเวลานี้แสงที่ได้กำลังช่วยปลุกพลังงานในร่างกายแบบเงียบๆ ด้วยแล้ว มันทำให้เฮียยิ่งเคารพธรรมชาติมากขึ้นไปอีก เคยเห็นคนที่วันๆมีแต่ความเครียด ความโกรธ ความอาฆาตต่อโลกไหมหละ บางคนแค่โดนแดด แต่ไม่ได้ตากแดด การตากแดดคือปล่อยใจไปกับธรรมชาติ พูดคุยกับร่างกาย บอกเขาว่าเราจะทำตัวให้เป็นประโยชน์กับโลกใบนี้ ให้สมกับที่ใช้พลังงานของโลก

จะเช้าหรือเย็น สำคัญไม่เท่ากับความตั้งใจ เฮียว่าไม่ว่าชีวิตจะตื่นตอนไหน ถ้าเราให้เวลาแค่ 10–15 นาทีในแต่ละวัน ออกไปยืนให้แดดแตะหน้า แตะแขน หรือแค่ให้แสงลอดผ่านตาเบาๆ โดยไม่ต้องจ้องจ้าๆ ก็พอ แค่นี้ก็เป็นการให้ไมโทคอนเดรียได้หายใจ ได้ออกกำลังกายแบบของมัน และได้ส่งพลังกลับมาหาเราทั้งร่างกายและจิตใจ

สุดท้ายแล้ว แดดไม่ได้แบ่งชนชั้น ไม่เลือกว่าจะรักเฉพาะคนตื่นเช้า หรือโกรธคนตื่นสาย ขอแค่เรารู้จักเวลาและวิธีอยู่กับมันอย่างถูกจังหวะ แดดก็พร้อมจะให้เสมอ

This piece is the first in a series that will focus on things I think are a priority if your focus is similar to mine: building a strong family and safeguarding their future.

---

Choosing the ideal place to raise a family is one of the most significant decisions you will ever make. For simplicity sake I will break down my thought process into key factors: strong property rights, the ability to grow your own food, access to fresh water, the freedom to own and train with guns, and a dependable community.

A Jurisdiction with Strong Property Rights

Strong property rights are essential and allow you to build on a solid foundation that is less likely to break underneath you. Regions with a history of limited government and clear legal protections for landowners are ideal. Personally I think the US is the single best option globally, but within the US there is a wide difference between which state you choose. Choose carefully and thoughtfully, think long term. Obviously if you are not American this is not a realistic option for you, there are other solid options available especially if your family has mobility. I understand many do not have this capability to easily move, consider that your first priority, making movement and jurisdiction choice possible in the first place.

Abundant Access to Fresh Water

Water is life. I cannot overstate the importance of living somewhere with reliable, clean, and abundant freshwater. Some regions face water scarcity or heavy regulations on usage, so prioritizing a place where water is plentiful and your rights to it are protected is critical. Ideally you should have well access so you are not tied to municipal water supplies. In times of crisis or chaos well water cannot be easily shutoff or disrupted. If you live in an area that is drought prone, you are one drought away from societal chaos. Not enough people appreciate this simple fact.

Grow Your Own Food

A location with fertile soil, a favorable climate, and enough space for a small homestead or at the very least a garden is key. In stable times, a small homestead provides good food and important education for your family. In times of chaos your family being able to grow and raise healthy food provides a level of self sufficiency that many others will lack. Look for areas with minimal restrictions, good weather, and a culture that supports local farming.

Guns

The ability to defend your family is fundamental. A location where you can legally and easily own guns is a must. Look for places with a strong gun culture and a political history of protecting those rights. Owning one or two guns is not enough and without proper training they will be a liability rather than a benefit. Get comfortable and proficient. Never stop improving your skills. If the time comes that you must use a gun to defend your family, the skills must be instinct. Practice. Practice. Practice.

A Strong Community You Can Depend On

No one thrives alone. A ride or die community that rallies together in tough times is invaluable. Seek out a place where people know their neighbors, share similar values, and are quick to lend a hand. Lead by example and become a good neighbor, people will naturally respond in kind. Small towns are ideal, if possible, but living outside of a major city can be a solid balance in terms of work opportunities and family security.

Let me know if you found this helpful. My plan is to break down how I think about these five key subjects in future posts.

'The Cantillon Effect: When new money is printed, those closest to the source (banks, elites) benefit first, buying assets before prices rise. Others lose purchasing power as inflation hits later. If people find out how this works, they will riot.' -Bitcoin for Freedom

Just think about it. Your employer gives you a 5% raise. The Fed (central banks in general) prints 7% more dollars/euros/Fiat. You just got a 2% pay cut. This isn't a conspiracy theory. This is how fiat money steals from the working class every single day. This is why I support Bitcoin.

Anilsaidso: 'Saving in fiat currency is no longer an option. A 2% inflation rate means you lose 1/3 of your purchasing power over 20yrs. At 5% inflation, you lose 60%. And at 10% you've burnt 85%. Reduce your uncertainty. Save in Bitcoin.' https://i.ibb.co/N661BdVp/Gr-Rwdg-OXc-AAWPVE.jpg

Coinbase estimates $180-$400 million in losses, remediation costs, and reimbursement following today’s cyber attack. https://i.ibb.co/jkysLtZ1/Gq-C7zl-W4-AAJ0-N6.jpg

Coinbase didn't get hacked. Coinbase employees sold customer data on the black market. Coinbase failed to protect customer data. This is why KYC is useless. The criminals have our driver's license scans. They have AI tools that can generate fake images and videos. KYC puts our identities at risk, makes onboarding more difficult, and rewards criminals. To make it even worse. Coinbase knew about the hack as early as January but only disclosed it publicly after being added to the S&P 500.

I will say it one more time! Don't buy your Bitcoin on KYC exchanges. KYC means handing over your identity to be leaked, sold, or extorted.

It was 2 days ago, see the bit on the 13th of May, that we saw a violent attack in Paris. Minimize the data you share with centralized tools. Store as much as you can locally. Always ask yourself what data am I giving and to whom? Remove the need for trust.

And for the love of God, Allah, or whatever god you are praying to...

DON'T LEAVE YOUR COINS ON A FREAKING EXCHANGE!!!!

💸Traditional Finance / Macro:

On the 12th of May:

👉🏽The S&P 500 has closed more than 20% above its April low, technically beginning a new bull market. We are now up +1,000 points in one month.

On the 13th of May:

👉🏽 Nvidia announces a partnership with Humain to build "AI factories of the future" in Saudi Arabia. Just one hour ago, Saudi Arabia signed an economic agreement with President Trump to invest $600 billion in the US.

🏦Banks:

👉🏽 No news

🌎Macro/Geopolitics:

On the 12th of May:

👉🏽Huge pressure is on the European Union to reach a trade deal. Equities and commodities bounce hard on news of China-US trade deal. "We have reached an agreement on a 90-day pause and substantially moved down the tariff levels — both sides, on the reciprocal tariffs, will move their tariffs down 115%." - Treasury Secretary Scott Bessent

Dollar and Yuan strong bounce. Gold corrects.

👉🏽After reaching a high of 71% this year, recession odds are now back down to 40%. The odds of the US entering a recession in 2025 fall to a new low of 40% following the US-China trade deal announcement.

👉🏽'Truly incredible:

1. Trump raises tariffs: Yields rise because inflation is back
2. Trump cuts tariffs: Yields rise because growth is back
3. Trump does nothing: Yields rise because the Fed won't cut rates Today, the bond market becomes Trump and Bessent's top priority.' - TKL

President Trump’s biggest problem persists even as trade deals are announced. Tariffs have been paused for 90 days, the US-China trade deal has been announced, and inflation data is down. Yet, the 10Y yield is nearing 4.50% again. Trump needs lower rates, but rates won’t fall.

👉🏽Last week a lot of talk on Japan’s Debt Death Spiral: Japan’s 40-year yield is detonating and the myth of consequence-free debt just died with it. One of the best explanations, you can read here:

👉🏽Michael A. Arouet: 'Eye-opening chart. Can a country with a services-based economy remain a superpower? Building back US manufacturing base makes a lot of strategic and geopolitical sense.' https://i.ibb.co/Q3zJY9Fc/Gqxc6-Pt-WQAI73c.jpg

On the 13th of May:

👉🏽There is a possibility of a “big, beautiful” economic rebalancing, Treasury Secretary Scott Bessent says at an investment forum in Saudi Arabia. The “dream scenario” would be if China and the US can work together on rebalancing, he adds

Luke Gromen: It does roll off the tongue a whole lot nicer than "We want to significantly devalue USD v. CNY, via a gold reference point."

Ergo: The price of gold specifically would rise in USD much more than it would in CNY, while prices for other goods and services would not, or would do so to a lesser degree.

👉🏽 Dutch inflation rises to 4.1 percent in April | CBS – final figure. Unchanged compared to the estimate.

👉🏽Philipp Heimberger: This interesting new paper argues that cuts to taxes on top incomes disproportionately benefit the financial sector. The finance industry gains more from top-income tax cuts than other industries. "Cuts in top income tax rates increase the (relative) size of the financial sector"

Source

Kinda obvious, innit?

👉🏽US CPI data released. Overall good results and cooler than expected month-over-month and year-over-year (outside of yearly core). U.S. inflation is down to 2.3%, lower than expected.

On the 14th of May:

👉🏽'The US government cannot afford a recession: In previous economic cycles, the US budget deficit widened by ~4% of GDP on average during recessions. This would imply a ~$1.3 trillion deterioration of US government finances if a recession hits in 2025. That said, if the US enters a recession, long-term interest rates will likely go down.

A 2-percentage-point decrease in interest rates would save ~$568 billion in annual interest payments. However, this means government finances would worsen by more than DOUBLE the amount saved in interest due to a recession. An economic downturn would be incredibly costly for the US government.' -TKL

On the 15th of May:

👉🏽'In the Eurozone and the UK, households hold more than 30% of their financial assets in fiat currencies and bank deposits. This means that they (unknowingly?) allow inflation to destroy their purchasing power. The risks of inflation eating up your wealth increase in a debt-driven economic system characterized by fiscal dominance, where interest rates are structurally low and inflation levels and risks are high. There is so much forced and often failed regulation to increase financial literacy, but this part is never explained. Why is that, you think?' - Jeroen Blokland https://i.ibb.co/zWRpNqhz/Gq-jn-Bn-X0-AAmplm.png

On the 16th of May:

👉🏽'For the first time in a year, Japan's economy shrank by -0.7% in Q1 2025. This is more than double the decline expected by economists. Furthermore, this data does NOT include the reciprocal tariffs imposed on April 2nd. Japan's economy is heading for a recession.' -TKL

👉🏽'246 US large companies have gone bankrupt year-to-date, the most in 15 years. This is up from 206 recorded last year and more than DOUBLE during the same period in 2022. In April alone, the US saw 59 bankruptcy filings as tariffs ramped up. So far this year, the industrials sector has seen 41 bankruptcies, followed by 31 in consumer discretionary, and 17 in healthcare. According to S&P Global, consumer discretionary companies have been hit the hardest due to market volatility, tariffs, and inflation uncertainty. We expect a surge in bankruptcies in 2025.' -TKL

👉🏽'Moody's just downgraded the United States' credit rating for the FIRST time in history. The reason: An unsustainable path for US federal debt and its resulting interest burden. Moody's notes that the US debt-to-GDP ratio is on track to hit 134% by 2035. Federal interest payments are set to equal ~30% of revenue by 2035, up from ~18% in 2024 and ~9% in 2021. Furthermore, deficit spending is now at World War 2 levels as a percentage of GDP. The US debt crisis is our biggest issue with the least attention.' - TKL

Still, this is a nothing burger. In August 2023, when Fitch downgraded the US to AA+, and S&P (2011) the US became a split-rated AA+ country. This downgrade had almost no effect on the bond market. The last of the rating agencies, Moodys, pushed the US down to AA+ today. So technically it didn’t even change the US’s overall credit rating because it was already split-rated AA+, now it’s unanimous AA+.

Ergo: Nothing changed. America now shares a credit rating with Austria and Finland. Hard assets don’t lie. Watch Gold and Bitcoin.

https://i.ibb.co/Q7DcWY2P/Gr-K66i-EXIAAKh-MR.jpg

RAY DALIO: Credit Agencies are UNDERSTATING sovereign credit risks because "they don't include the greater risk that the countries in debt will print money to pay their debts" with devalued currency.

👉🏽US consumer credit card serious delinquencies are rising at a CRISIS pace: The share of US credit card debt that is past due at least 90 days hit 12.3% in Q1 2025, the highest in 14 YEARS. The percentage has risen even faster than during the Great Financial Crisis.' - Global Markets Investor

https://i.ibb.co/nNH9CxVK/Gr-E838o-XYAIk-Fyn.png

On the 18th of May:

👉🏽Michael A. Arouet: 'Look at ten bottom of this list. Milei has not only proven that real free market reforms work, but he has also proven that they work fast. It’s bigger than Argentina now, no wonder that the left legacy media doesn’t like him so much.' https://i.ibb.co/MDnBCDSY/Gr-Npu-KKWMAAf-Pc.jpg

On the 19th of May: 👉🏽Japan's 40-year bond yield just hit its highest level in over 20 years. Japan’s Prime Minister Ishiba has called the situation “worse than Greece.” All as Japan’s GDP is contracting again. You and your mother should be scared out of your fucking minds. https://i.ibb.co/rGZ9cMtv/GTXx-S7-Cb-MAAOu-Vt.png

👉🏽 TKL: 'Investors are piling into gold funds like never before: Gold funds have posted a record $85 BILLION in net inflows year-to-date. This is more than DOUBLE the full-year record seen in 2020. At this pace, net inflows will surpass $180 billion by the end of 2025. Gold is now the best-performing major asset class, up 22% year-to-date. Since the low in October 2022, gold prices have gained 97%. Gold is the global hedge against uncertainty.'

We 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!

Here’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’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.

Hopefully people out there that are importers, exporters, agents, traders, wholesalers in various types of goods, will eventually post, or at the very least find some possible business leads, contacts and most importantly reviews on payments methods using Bitcoin around the World.

The Good News

1. Wholesale and Retail merchants have heard the Independent, Democratic and Republican parties are speaking in a positive tone about Bitcoin and the C word in general. Whether any of them actually will do anything in the future is another issue, note the fact that Bitcoin and the C word is being brought up in a positive way is a good.

2. Bitcoin Dev groups are opening up in more places around the World and obviously some general education, terminology and introduction to Lightning, Nostr, and hybrid point of sale systems are slowly be added to merchants retail and wholesale.

3. Shopify, As the majority of business are using Shopify, Open Node is easily added as a payment method to accept Bitcoin. (I'm using it) works fine, had to as ibexpay left supporting the USA.

4. "Just hodl" comes up more and more in conversations with my peers, asking with a confused look "When do we use it, circulate it in transacting buying or selling goods (wholesale), NOT just a cup of coffee, we are just suppose to hodl, and never use it ?

5. We have SN, we should be thankful it's a positive tool.

If anyone wants to communicate with other manufacturers, wholesalers, B2B merchants, importers, exporters, agents selling goods of any type consider reaching out as a post on SN, or contacting me directly, hopefully that you are considering using Bitcoin as the payment method.

由于gmail在中国被防火墙拦截了，无法打开，不想错过邮件通知。

通过自建ntfy接受gmail邮件通知。 怎么自建ntfy，后面再写。

---

2024年08月13日更新：

修改不通过添加邮件标签来标记已经发送的通知，通过Google Sheets来记录已经发送的通知。

为了不让Google Sheets文档的内容很多，导致文件变大，用脚本自动清理一个星期以前的数据。

---

准备工具

• Ntfy服务
• Google Script
• Google Sheets

操作步骤

1. 在Ntfy后台账号，设置访问令牌。
2. 添加订阅主题。
3. 进入Google Sheets创建一个表格.记住id，如下图：
4. 进入Google Script创建项目。填入以下代码（注意填入之前的ntfy地址和令牌）：

```javascript function checkEmail() { var sheetId = "你的Google Sheets id"; // 替换为你的 Google Sheets ID var sheet = SpreadsheetApp.openById(sheetId).getActiveSheet();

// 清理一星期以前的数据 cleanOldData(sheet, 7 * 24 * 60); // 保留7天（即一周）内的数据

var sentEmails = getSentEmails(sheet);

var threads = GmailApp.search('is:unread'); Logger.log("Found threads: " + threads.length);

if (threads.length === 0) return;

threads.forEach(function(thread) { var threadId = thread.getId();

if (!sentEmails.includes(threadId)) {
  thread.getMessages().forEach(sendNtfyNotification);
  recordSentEmail(sheet, threadId);
}

}); }

function sendNtfyNotification(email) { if (!email) { Logger.log("Email object is undefined or null."); return; }

var message = `发件人: ${email.getFrom() || "未知发件人"} 主题: ${email.getSubject() || "无主题"}

内容: ${email.getPlainBody() || "无内容"}`;

var url = "https://你的ntfy地址/Gmail"; var options = { method: "post", payload: message, headers: { Authorization: "Bearer Ntfy的令牌" }, muteHttpExceptions: true };

try { var response = UrlFetchApp.fetch(url, options); Logger.log("Response: " + response.getContentText()); } catch (e) { Logger.log("Error: " + e.message); } }

function getSentEmails(sheet) { var data = sheet.getDataRange().getValues(); return data.map(row => row[0]); // Assuming email IDs are stored in the first column }

function recordSentEmail(sheet, threadId) { sheet.appendRow([threadId, new Date()]); }

function cleanOldData(sheet, minutes) { var now = new Date(); var thresholdDate = new Date(now.getTime() - minutes * 60 * 1000); // 获取X分钟前的时间

var data = sheet.getDataRange().getValues(); var rowsToDelete = [];

data.forEach(function(row, index) { var date = new Date(row[1]); // 假设日期保存在第二列 if (date < thresholdDate) { rowsToDelete.push(index + 1); // 存储要删除的行号 } });

// 逆序删除（从最后一行开始删除，以避免行号改变） rowsToDelete.reverse().forEach(function(row) { sheet.deleteRow(row); }); }

```

4.Goole Script需要添加gmail服务，如图：

5.Google Script是有限制的不能频繁调用，可以设置五分钟调用一次。如图：

结尾

本人不会代码，以上代码都是通过chatgpt生成的。经过多次修改，刚开始会一直发送通知，后面修改后将已发送的通知放到一个“通知”的标签里。后续不会再次发送通知。

如需要发送通知后自动标记已读，可以把代码复制到chatgpt给你写。

“Any society that sets intellectual development as its goal will continually progress, without end—until life is liberated from problems and suffering. All problems can ultimately be solved through wisdom itself.

The signpost pointing toward ‘wisdom’ is the ability to think—or what is called in Dhamma terms, ‘yoniso-manasikāra,’ meaning wise or analytical reflection. Thinking is the bridge that connects information and knowledge with insight and understanding. Refined or skillful thinking enables one to seek knowledge and apply it effectively.

The key types of thinking are:

• Thinking to acquire knowledge
• Thinking to apply knowledge effectively In other words, thinking to gain knowledge and thinking to use that knowledge. A person with knowledge who doesn’t know how to think cannot make that knowledge useful. On the other hand, a person who thinks without having or seeking knowledge will end up with nothing but dreamy, deluded ideas. When such dreamy ideas are expressed as opinions, they become nonsensical and meaningless—mere expressions of personal likes or dislikes.

In this light, the ‘process of developing wisdom’ begins with the desire to seek knowledge, followed by the training of thinking skills, and concludes with the ability to express well-founded opinions. (In many important cases, practice, testing, or experimentation is needed to confirm understanding.)

Thus, the thirst for knowledge and the ability to seek knowledge are the forerunners of intellectual development. In any society where people lack a love for knowledge and are not inclined to search for it, true intellectual growth will be difficult. That society will be filled with fanciful, delusional thinking and opinions based merely on personal likes and dislikes. For the development of wisdom, there must be the guiding principle that: ‘Giving opinions must go hand-in-hand with seeking knowledge. And once knowledge is gained, thinking must be refined and skillful.’”

— Somdet Phra Buddhaghosacariya (P.A. Payutto) Source: Dhamma treatise “Organizing Society According to the Ideals of the Sangha”

Note: “Pariyosāna” means the complete conclusion or the final, all-encompassing end.

---

“We must emphasize the pursuit of knowledge more than merely giving opinions. Opinions must be based on the most solid foundation of knowledge.

Nowadays, we face so many problems because people love to express opinions without ever seeking knowledge.”

— Somdet Phra Buddhaghosacariya (P.A. Payutto)

Riscos

Os maiores riscos que vejo hoje, para uma empresa tão sólida como Wege são:

1. Instabilidade Econômica Global e Regional, qualquer flutuação em mercado chave atuante pode representar um risco.
2. Inflação e Custo de Insumos, principalmente aço e cobre que são matérias prima base.
3. Políticas Tarifárias e Protecionismo, se o homem laranja dos EUA impor tarifas. Pode afetar sim os negócios da empresa como um todo.

Markdown + X, Y, Z is a problem, but Markdown + N can fix that.
Where N = any type of Nostr event.

Whatever Markup language you choose, people will be referencing other Nostr events in it all the time. Since apps have to find ways to display those events (or the links to them) anyway, we mights as well use that as an opportunity.

Why can't Tables, for example, be embedded Nostr events?

Switching from Markdown to Asciidocs (because it has tables and some more technical stuff) still doesn’t make Tables a great experience. On mobile, Tables are notoriously hard to display in a useful way. It depends on the use case, size of the table, etc….

Creators need guarantees on these things being displayed the way they intended.
There’s a reason why most authors just embed pictures of tables instead. It has little to do with Markdown not really supporting tables and more with them ensuring readability and appropriate styling.

So what if you enhance Markdown not only with embedded Nostr Events but also with something like Hypernotes Widgets that serve as a preview/display for those Nostr Events?

That way: - you are still using the most simple and popular markup language - devs “only” have to implement one extra thing (Hypernotes) that handles all the complexity and extensibility from there - authors can create articles and wiki entries with interactive elements in them, can have the guarantee that they display properly, can use any styling that suits them, etc… - the worst case scenario of reading it in a random crappy app still displays the link to the event (including it's explanatory metadata)

Imagine custom interactive graphs, polls, media players, products, … embedded in articles BUT limited to the Nostr-verse for all interaction and data fetching.

(this article will be updated with UI prototypes and further thoughts)

@ 1c9dcd8f:1852f704

Many strange spells are effected by the means of a dead man’s hand—chiefly to produce butter in the churn. The milk is stirred round nine times with the dead hand, the operator crying aloud all the time, “Gather! gather! gather!” While a secret form of words is used which none but the initiated know.

Another use is to facilitate robberies. If a candle is placed in a dead hand, neither wind nor water can extinguish it. And if carried into a house the inmates will sleep the sleep of the dead as long as it remains under the roof, and no power on earth can wake them while the dead hand holds the candle.

---

For a mystic charm, one of the strongest known is the hand of an unbaptized infant fresh taken from the grave in the name of the Evil One.

---

A dead hand is esteemed also a certain cure for most diseases, and many a time sick people have been brought to a house where a corpse lay that the hand of the dead might be laid on them.

--

The souls of the dead who may happen to die abroad, greatly desire to rest in Ireland. And the relations deem it their duty to bring back the body to be laid in Irish earth. But even then the dead will not rest peaceably unless laid with their forefathers and their own people, and not amongst strangers.

---

A young girl happened to die of a fever while away on a visit to some friends, and her father thought it safer not to bring her home, but to have her buried in the nearest churchyard. However, a few nights after his return home, he was awakened by a mournful wail at the window, and a voice cried, “I am alone; I am alone; I am alone!” Then the poor father knew well what it meant, and he prayed in the name of God that the spirit of his dead child might rest in peace until the morning. And when the day broke he arose and set off to the strange burial ground, and there he drew the coffin from the earth, and had it carried all the way back from Cork to Mayo; and after he had laid the dead in the old graveyard beside his people and his kindred, the spirit of his child had rest, and the mournful cry was no more heard in the night.

---

The corner of a sheet that has wrapped a corpse is a cure for headache if tied round the head.

---

The ends of candles used at wakes are of great efficacy in curing burns.

---

A piece of linen wrap taken from a corpse will cure the swelling of a limb if tied round the part affected.

---

It is believed that the spirit of the dead last buried has to watch in the churchyard until another corpse is laid there; or has to perform menial offices in the spirit world, such as carrying wood and water until the next spirit comes from earth. They are also sent on messages to earth, chiefly to announce the coming death of some relative, and at this they are glad, for then their time of peace and rest will come at last.

---

If any one stumbles at a grave it is a bad omen; but if he falls and touches the clay, he will assuredly die before the year is out.

---

Any one meeting a funeral must turn back and walk at least four steps with the mourners.

---

If the nearest relative touches the hand of a corpse it will utter a wild cry if not quite dead.

---

On Twelfth Night the dead walk, and on every tile of the house a soul is sitting, waiting for your prayers to take it out of purgatory.

---

There are many strange superstitions in the western islands of Connemara. At night the dead can be heard laughing with the fairies and spinning the flax. One girl declared that she distinctly heard her dead mother’s voice singing a mournful Irish air away down in the heart of the hill. But after a year and a day the voices cease, and the dead are gone for ever.

---

It is a custom in the West, when a corpse is carried to the grave, for the bearers to stop half way, while the nearest relatives build up a small monument of loose stones, and no hand would ever dare to touch or disturb this monument while the world lasts.

---

When the grave is dug, a cross is made of two spades, and the coffin is carried round it three times before being placed in the clay. Then the prayers for the dead are said, all the people kneeling with uncovered head.

Ovaj post sam objavio 24.01.2024. godine na Redditu povodom tri decenije od uvođenja Novog dinara kao rešenja za hiperinflaciju u Saveznoj Republici Jugoslaviji na šta su pojedini besni nokoineri sa te društvene mreže osuli drvlje i kamenje na mene. Od starih budalaština da je Bitkoin bezvredan, da nije oblik novca već finansijsko ulaganje, preko pravdanja svrhe inflacije, sve do potpune nemoći da se argumentima opovrgne nepobitna istina i pozivanja moderatora da me banuju. 🙃

Cena Bitkoina tada je bila oko $40.000. :)

Osim glavnog posta, ovde ću navesti i moje odgovore na neutemeljene i neinformisane tvrdnje besnih nokoinera. :) Da se sačuva od zaborava!

Juče se navršilo 30 godina "Deda Avramove reforme".

Dan kada je rođen novi dinar, a Deda Avram sasekao hiperinflaciju

Kako nas je deda Avram spasio pre 30 godina: Neverovatno svedočenje tvorca „super dinara“ o jednoj od najgorih godina u istoriji Srbije

Dva jajeta – nedeljna profesorska plata: Kako se živelo u hiperinflaciji i šta je uradio Avramović

Vikipedija: Jugoslovenski dinar

„U julu '93. godine u Jugoslaviji nisi mogao skoro ništa da kupiš i niko za dinare nije hteo ništa da prodaje“, pisao je Avramović. Centralno-bankarska prevara se nastavlja jer je već do kraja 1995. dinar oslabio prema marki za 70% (1 dinar = 3.4 DM), a u decembru 2000. je taj kurs već bio 30.5 dinara za 1 DM (-96.7% od uvođenja novog dinara). To samo pokazuje da redenominacija valute tj. "brisanje nula" nije nikako čudo i viđano je puno puta kroz istoriju)

Ako je reformom iz januara '94 god. 1 novi dinar vredeo kao 1 nemačka marka, zatim od 2002. uveden evro čime je realna vrednost marke (samim tim i dinara) prepolovljena, a danas 1 EUR vredi oko 117 RSD, to znači da je "deda Avramov dinar" prema evru već obezvređen 59.91 puta za 30 godina. Dakle devalvacija dinara od 5991% od 1994. godine, a svakako još veća izražena kroz dobra i usluge jer su i nemačka marka do 2002. i evro od svog uvođenja iste godine prošli kroz sopstvenu inflaciju. Sam evro je izgubio oko 38% vrednosti od 2002. godine. Tako da se može reći da i "deda Avramov dinar" već uveliko prolazi kroz hiperinflaciju koja je samo razvučena na mnogo duži vremenski period (ne brinite - znam "zvaničnu" definiciju hiperinflacije - još jedan "gaslighting" centralno-bankarskog kartela da zabašuri šta se iza brda valja). Jer šta je inflacija od preko 5991% nego višedecenijska hiperinflacija?! Kako ne shvata gigantske razmere ove prevare?!

ISPRAVKA: Dinar nije nominalno izgubio 23400% (234x) vrednosti prema nemačkoj marki/evru od 1994. godine, već 59.91x odnosno 5991%. I danas na sajtu NBS postoji zvanični srednji kurs marke prema dinaru od 59,91:1. Realno, obezvređivanje dinara i evra prema robama i uslugama je puno veće, pošto su cene roba i usluga izražene u evrima ubrzo udvostručene u periodu nakon uvođenja evra. Hvala članu DejanJwtq na ispravci i izvinjenje svima od mene zbog greške.

Dafiment i Jugoskandik ("Dafina i Jezda") su bili samo državna konstrukcija da se izvuku devize iz ruku naivnih investitora da bi te devize nešto kasnije poslužile kao tobožnja rezerva za novi dinar. Ova gigantska prevara je unapred bila planirana, a Deda Avram iskorišćen kao marioneta tadašnjeg režima.

Inače lista država koje su izvršile redenominaciju valute kroz "brisanje nula" je poprilično dugačka i radi se o uobičajenoj pojavi kroz istoriju još od Haitija 1813. godine, a poslednji put su to uradile Sijera Leone i Kolumbija 2021. godine. Odavno je zaboravljeno da je (SR) Jugoslavija devedesetih to učinila još 1990. (10.000:1), 1992. (10:1), 1993. (1.000.000:1) i 1994. pre Avramovića (1.000.000.000∶1) ali je ovaj dinar trajao samo 23 dana. Tako da Deda Avram nije izmislio toplu vodu.

U SFRJ je izvršena jedna redenominacija 1966. godine u odnosu 10.000:1.

Wikipedia: Redenomination

Kome i dalje nije jasno zašto Bitkoin neka više puta pažljivo pročita ove tekstove iznad: oblik novca koji se ne može redenominirati, veoma lako konfiskovati i izdavati bez ikakve kontrole i pokrića. Potpuno nezavistan od kaprica korumpiranih i od realnosti otuđenih političara i centralnih bankara. Veoma je bitno da postoji ovakav oblik novca koji nije podložan ovakvim manipulacijama od strane ljudskog faktora i da postoji slobodan izbor da se taj oblik novca odabere za štednju i transakcije: barem od strane onih koji ga razumeju, ovi koji ne žele da razumeju neka i dalje pristaju da budu pljačkani - njima ionako nema pomoći.

Komentari

brainzorz: Da, ali ako cemo realno bitkoin ne sluzi kao oblik novca, vec kao finansijsko ulaganje.

Bar je tako za nas i vecinu ljudi po svetu u praktičnom smislu. Jer 99.99% ljudi ili koliko vec prime platu u svojoj lokalnoj valuti, trose istu na redovan zivot, a ostatak (ako ga ima) investiraju. Slazem se da lokalne valute imaju svoj neki rizik, koji je veci u banana drzavi i da cuvanje svog kapitala u turbulentnom periodu u istoj je jako losa ideja.

Kada tako posmatras onda se mogu vuci pararele izmedju ostalih aseta, poput ETFova na primer i onda dolazimo do gomile problema sa bitkoinom.

@BTCSRB: Bitkoin se ne može porediti sa ETF-ovima pošto ETF-ove i ostale investicione instrumente ne možeš koristiti kao novac jer oni nisu "bearer assets" kao što jeste BTC. BTC eliminiše potpuno inflaciju (jer džabe ti keš u slamarici kao "bearer asset" kada je podložan inflaciji) i potrebu za posrednikom kod elektronskih plaćanja.

brainzorz: Ali on to eleminise samo u teoriji, sad da odem u pekaru, moram platiti u lokalnoj valuti, sad da li cu prodati bitkoin ili etf, prilicno je slicno.

Jedino sto mogu bitkoin zamenuti uzivo (ilegalno) sa nekim, pa tu jeste zamenjen posrednik. Ali provizije povlacenja su uglavnom zanemarljive, naspram ostalih parametara investicionog sredstva.

Neke stvari se mogu direktno platiti za bitkoin, ali to je ekstremno retko u stvarnom zivotu vecine ljudi.

@BTCSRB: Slažem se ali u uslovima hiperinflacije i visoke inflacije kakvu danas imamo u Argentini, Venecueli, Zimbabveu, Libanu, Turskoj itd. sve više ljudi direktno vrši transakcije u kriptovalutama, naročito "stablecoinima" poput USDT Tethera. Priznajem da u tim transakcijama BTC zaostaje upravo zbog volatilnosti ali je vršenje brzih i jeftinih transakcija svakako moguće putem Lightning mreže. Sve te lokalne valute su izgubile značajnu vrednost i prema USDT i prema BTC-u, odnosno BTC konstantno probija rekordnu vrednost kada se denominuje u tim valutama. I u tim državama je adopcija kriptovaluta najraširenija.

HunterVD: Kako valuta u koju se upumpavaju nepostojeci dolari i evri moze biti realna i dobra. A USDT tek da ne spominjem. Mozes uvek revi jer joj ljudi veruju, al ta vera u nesto ide samo do odredjenog nivoa.

@BTCSRB: Godinama kupujem BTC od svake plate, praktično štedim u njemu i kupovna moć mi vremenom raste denominirana u evrima i dinarima. To isto rade na desetine hiljada ljudi širom sveta. Kako su ti realni dinari i evri koje ubacujem svakog meseca koje sam zaradio od svog realnog rada - "nepostojeći"?

Kako dolari i evri koji se štampaju ni iz čega mogu biti realni i dobri kao valuta?

HunterVD: Pa eto bas to. Ulaze se nepostojeci novac u BTC i onda se prica o nekoj novoj valuti. Nije sija nego vrat, BTC ima jedino vrednost dok se upumpava taj lazni novac u njega. FIAT novac kolko tolko nastaje radom i proizvodnjom dobara, ne sav FIAT novac al neki deo, dok se BTC zasniva skroz na upumpavanje tog istog FIAT novca i dobroj volji i zeljama da magicne brojke idu navise.

@BTCSRB: Itekako je moguće izraziti cenu svih ostalih dobara i usluga kroz BTC i postojanje i vrednost BTC-a uopšte ne zavisi od fiat novca. Štaviše, gotova sva dobra i usluge dugoročno postaju jeftiniji kada se mere kroz BTC. Sutra kada bi fiat novac nestao BTC bi i dalje imao vrednost, čak i veću nego danas.

https://www.pricedinbitcoin21.com/

HunterVD: Naravno da je moguce izraziti cene svakodnevnih proizvoda u BTCu. Cene svakodnevnih proizvoda je moguce izraziti u cemu god pozelis, evo npr broj radnih sati koji je potreban da se proizvede taj proizvod i onda se uporedi sa cenom radnih sati i cene na polici, mozes ga uracunavati i u dobrima , jedan iphone kosta tolko i tolko KG juneceg mesa..... nista cudno. Takodje cene proizvoda pokazuju pad u odnosu sa BTCom jer je BTC masivno porastao u poslednjih 5-6 godina. Sta ce biti kad BTC stagnira ili pada kako se u tom periodu odnose cene, a da BTC je store of value i namenjen je samo da se cuva izvinte molim vas moja greska. Ni druge kripto valute nisu nista bolje. Ljudi koji su zaradili na BTCu svaka cast eto imali su pameti i srece , al sad kako je cena sve veca, inflacija sve losija i kamatne stope sve vise postace sve teze i teze dolaziti do novca a kamo li intvestirati ga u nesto rizicno ko kripto valute tako da ce i BTC sve manje rasti sto zbog velicine market cap-a sto zbog toga sto ljudi i firme imaju sve manje novca za ulagati. Dal ce btc moci da se uzbori sa inflacijom i losim uslovima to tek treba da se vidi. Tako da videcemo u narednom periodu koliko ce se ta priva o BTC kao store of value i nacinu odbrane od inflacije obistiniti. Licno ne verujem da ce BTC ikad biti zvanicno sredstvo placanja.

@BTCSRB: Cena svega se može izraziti kroz sve ostalo ali šta od svega toga najbolje vrši funkciju novca? BTC bolje vrši funkciju novca u većini okolnosti od gotovo svih stvari.

Šta će biti sa BTC videće se i oni koji veruju u njega će biti najzaslužniji za njegov uspeh jer su obezbeđivali potražnju kada su kola išla nizbrdo i za to biti asimetrično nagrađeni, ali će i puno izgubiti ako se pokaže da nisu u pravu. Pukovnici ili pokojnici. Po meni je to cilj zbog koga vredi rizikovati, pa i bankrotirati a cilj je da se centralno-bankarski kartel učini manje relevantnim.

Znaš i sam da fiat sistem ne može da preživi i izbegne imploziju bez konstantnog uvećanja mase novca u opticaju i zato se uopšte ne plašim za BTC i spavam mirno. BTC sigurno neće rasti istom brzinom kao prvih 15 godina ali moje očekivanje je svakako ubedljivo nadmašivanje svetske inflacije i obezvređivanja. Ne vidim kako sistem može da opstane bez novog QE kada god se on desi, u suprotnom imamo deflatornu spiralu.

Ne mora da bude zvanično sredstvo plaćanja, dovoljno da meni kao pojedincu služi za to dok god ima ljudi koji ga prihvataju, a ima ih puno. I da niko u tome ne može da nas spreči.

loldurrr: Ali i BTC je postao, u neku ruku, berzanska roba. Imaš market cap izražen u dolarima, koji je danas, npr. 2 triliona $, za mjesec dana 500 milijardi. Isto kao i dolar, samo volatilnije. Zato i kažem, da je to sve rezultat ponude i tražnje. Hipotetički, ja da imam milion BTC i odlučim to danas prodati, enormno ću oboriti cenu BTC. Ako je to valuta nezavisna od vanjskih uticaja - zašto će pasti toliko, kada imamo ograničenu količinu BTC-a. Svima je i dalje u podsvesti vrednost BTC izražena u USD, tako da je to isto kao i dinar, franak, akcija CocaCola i sl. Bar za sada...

A mogućnosti za korištenje BTC za robna plaćanja su mizerna. Ima li na vidiku mogućnosti da se vrednost nafte počne izražavati u BTC?

@BTCSRB: Meriti Bitkoin direktno prema robama i uslugama je itekako moguće i kada ga tako meriš, a ne prema fiat novcu, dugoročno cene gotovo svih roba i usluga padaju prema Bitkoinu. Cene svega izražene kroz BTC neće nestati ni u slučaju nestanka fiat novca, dolar sutra da prestane da postoji nikoga ne sprečava da izražava cene svega kroz BTC. Dolar i ostale valute nisu potrebni Bitkoinu.

Unlikely-Put-5524: Imam samo jedno pitanje za one "koji vide iza svega" i pronikli su bankarsku prevare da porobi čovečanstvo... Kako ne postoji mogućnost da je BTC i kripto nastao iz iste kuhinje i predstavlja ultimativni način za porobljavanje?

2% novčanika poseduje 95% svog BTC-a koji nije izgubljen. Znači da centralizacija može biti maksimalna...

@BTCSRB: Količina BTC-a u posedu ne daje kontrolu nad pravilima protokola i većinski vlasnici ne mogu da štampaju nove novčiće i tako uvećaju konačnu količinu u opticaju. Mogu samo da kratkoročno obore cenu i tako samo ostanu sa manje BTC-a koji imaju pošto će tržište vremenom apsorbovati te dampovane koine.

Unlikely-Put-5524: A mogu i dugoročno da obore cenu. Hajde da kažemo da imaš sada 10 BTC-a gde svaki vredi 40k

Veliki dumpu-ju ceo svoj bag u kontinutitetu kao što sad radi GS i posle godinu dana tvoj BTC sad vredi 4k, zašto misliš da bi ljudi nastavili da ga drže? Posebno ako znamo da ga 97% kupuje da bi zaradili, a ne zato što žele da ga koriste kao sredstvo plaćanja.

Ja bih ore BTC gledao kao commodity, jer sa svojim deflatornim svojstvima ne može biti valuta za plaćanje.

Takođe postoji i doomsday scenario gde jednostavno mogu svi da se dogovore da je ilegalan i to je onda to. Ovo mi deluje kao gotovo neverovatno, ali po meni je bilo koji maksimalizam potpuno detinjasto razmišljanje.

@BTCSRB: Pa padao je toliko puta za preko 70% i uvek se vraćao jer si uvek imao ljude koji su bili spremni da ga kupuju po bilo kojoj ceni, uključujući i mene. Pošto se ne može štampati, na kraju će ovi prodavci ostati bez BTC-a za prodaju i tržište apsorbovati čak i njihov "sell pressure". A ovi veliki koji drže tolike količine itekako dobro znaju vrednost toga što poseduju i nema smisla da svu količinu koju drže prodaju za inflatorni novac - prodavaće da bi finansirali svoj životni stil ili investiraju u biznise ili će ga koristiti kao kolateral za fiat pozajmice - ako raspolažu tolikim količinama i mogu da kontrolišu tržište nemaju strah da će im kolateral biti likvidiran.

Većina ljudi su fiat maksimalisti samim tim što su 100% u fiat novcu pa ne razmišljaju u pravcu doomsday scenarija kakav je upravo bila hiperinflacija devedesetih.

Romeo_y_Cohiba: Niko ti ne brani da ulažeš u bitcoin pod uslovom da znaš da je rizičniji od gotovog novca, štednje po viđenju, oročene štednje, obveznica, nekretnina, akcija, raznoraznih etfova, private equitya i derivata.

Drugim rečima ako ti je ok da danas uložiš 1000e, da za nedelju dana to vredi 500e, za mesec 1500 a za pola godina 300e ili 0 samo napred. Većini ljudi to nije ok.

Razlog zašto pamtimo Avrama je jer njegov dinar i dan danas koristimo. Prethodne uzastopne reforme nisu uspele kao što si i sam primetio.

Takođe, nije u pitanju "centralno-bankarska" prevara jer se ništa od toga ne bi desilo da ovom "odozgo" nisu zatrebale pare za finansiranje izvesnih stvari.

I dan danas, izvesni političar(i) izađu na TV i kažu da su "našli" novac za neki svoj genijalni plan i ljudi to puše. To u prevodu najčešće znači da će da nagna centralnu banku da mu doštampa novca i to nema veze sa bankama nego politikom..

@BTCSRB: Za investicione instrumente koje si naveo treba videti koliko su uspešno nadvladavali inflaciju prethodnih decenija i da li su očuvali kupovnu moć. Za štednju u banci i obveznice se i iz daleka vidi da nisu. US obveznice su u septembru imale drawdown od 48% od ATH iz 2020, a kao važe sa sigurnu investiciju. Čak i u momentu dospeća posle 10-30 godina jako teško čuvaju vrednost od inflacije.

A sada se zapitaj: da li zaista misliš da političari kontrolišu banke i bankare ili je možda obrnuto? Nisu političari ti koji su vlasnici krupnog kapitala.

Romeo_y_Cohiba: Ne investiraju svi na 10-30 godina za potrebe penzije. To je samo jedan od mnogo vidova i razloga investiranja. Nadvladavanje inflacije je isto tako samo jedan od kriterijuma. Samo pogledaš u šta jedan penzioni fond u SAD-u investira(hint: nije btc i nisu samo akcije). Npr. neki penzioni fondovi su od skoro počeli da investiraju u private equity ali isključivo do 15% veličine portfolija. Počeće i sa kriptom u nekom trenutku ali mogu da potpišem da će biti u još manjem procentu nego PE. Niko nije blesav da grune teško stečeni novac u nešto tako rizično osim u jako malim iznosima.

Ne znam ko koga kontroliše ali Avram je bio daleko manji baja od Slobe 90ih i pitao se za stvari samo u meri koliko mu je bio dozvoljeno da se pita. Ratovanje košta i finansira se štampanjem novca, nisu to neke neshvatljive stvari. Da ne pričam da smo bili pod apsolutnim sankcijama celog sveta.

Virtual_Plenty_6047: Npr jedan od velikih uspeha Japana od pre par decenija je zahvaljujući devalvaciji njihove valute, pa samim tim izvoz im je bio relativno jeftin. Naš dinar je jak, i to odgovara uvozničkom lobiju.

Nažalost mi ionako ništa ne proizvodimo tako da ne verujem da bi nešto pomoglo ako bi devalvirali dinar. Al svakako ovo je jedna viša ekonomija za koju naši političari nisu dorasli.

@BTCSRB: Gde je običan čovek u tom velikom japanskom uspehu? Postali su zemlja starih i nesrećnih mladih ljudi koji ne mogu da pobegnu iz "hamster wheel-a". Imaju "debt to GDP" od preko 260%. Taj dug nikada neće vratiti, a uz to će povući u ambis pola sveta jer najveći držaoci američkog duga - 14.5%. Spolja gladac, iznutra jadac. Iako je malo degutantno da mi iz Srbije komentarišemo Japance, opet pitam: gde je prosečan Japanac u celoj ovoj igri?

Why Japan Is Facing a Financial Disaster

Preporučujem da pogledate dokumentarac "Princes of the Yen | The Hidden Power of Central Banks" snimljenom po istoimenoj knjizi profesora Riharda Vernera koji je otac kvantitativnog popuštanja (quantitative easing) i ekspert za japansku ekonomiju i bankarski sistem.

Virtual_Plenty_6047: Zato sam rekao od pre nekoliko decenija. Jer su do pre nekih 30 godina bili 50 godina ispred celog sveta, sad su 20 godina iza naprednog sveta. Japanci su svako specifični. Poenta mog komentara da postoji razlog za neke zemlje da oslabe svoju valutu, i može itekako dobro da radi ako se radi u sinergiji sa nekim drugim ekonomskim merama. Tako da odgovor na to opet pitam, ne znam gde je prosečni Japanac, uskoro tamo trebam da idem pa ću ti reći. :'D

Odgledao sam ja ovaj dokumentarac odavno, super je. Pročitao mnoge knjige, a ponajviše od Austrijske ekonomske škole gde su pojedinci (Hayek) bili prvi koji su zagovarali novu decentralizovanu valutu, bili su u toj školi mnogi koji su prvi pričali o problemu inflacije i šta je tačno inflacija, ali su bili i za kapitalizam. Ali ovo je zaista jedna visoka ekonomija, videćeš da nije baš sve tako jednostavno kao što misliš.

Malo si previše u kriptovalutama pa gledaš na sve drugo u ekonomiji sa prekorom, pogotovu na kapitalizam. Evo i ja sam sam dobro investiran u kripto (uglavnom u BTC) pa sam itekako svestan da sve to može na kraju da bude potpuna pizdarija.

p.s. Knjiga za preporuku: 23 stvari koje vam ne kazu o kapitalizmu

@BTCSRB: Nisam u kriptovalutama nego isključivo u BTC.

Nisam ja protiv kapitalizma samo što nije pravi kapitalizam kada ne postoji slobodno tržište novca, pa samim tim ne postoji uopšte slobodno tržište koliko god se činilo tako. Kada su ekonomski subjekti prisiljeni da koriste određeni oblik novca, a monetarna politika se centralno planira - po meni tu nema slobodnog tržišta niti kapitalizma. Npr. formiranje cene Bitkoina i transakcionih naknada je čisto slobodno tržište jer tu nema "bailout-a", a BTC mining industrija je pravi primer slobodnog tržišta u kapitalizmu. Čista ponuda i potražnja bez intervencionizma. Ako si neprofitabilan nema ti spasa i bankrotiraćeš i nema nikoga ko će ti priteći u pomoć. Niko nije "too big to fail".

Znam da sam se ovde usredsredio usko na jednu industriju ali se može primeniti na celokupnu ekonomiju. Države i centralne banke su suvišne i apsolutno pokvare sve čega se dotaknu pa će u slučaju potpune pizdarije odgovornost biti na njima, a ne na Bitkoinu i njegovim držaocima.

kutija_keksa: Evo zašto btc nije pogodan kao valuta:

-Volatilna vrednost. Vrednost btc se menja i do 200% godišnje, dok dolar ne trpi inflaciju vecu od 10% godišnje (mada je u redovnim uslovima tipa 3%). Čak i dinar, ako gledaš realnu kupovnu moć u prodavnici nema volatilnost preko 30% na godišnjem nivou (jedno 7 puta nižu od BTC) Ako danas kupim BTC u vrednosti od 15 USD ne znam da li ću sutra moći da kupim 10 ili 20 USD za isti taj BTC.

-„Gas fees” koji se plaćaju na svaku transakciju, u poređenjusa kešom koji nema takvih problema.

-Spor transfer novca. Arhitektura blockchaina ne dozvoljava mreži da procesuira više od 10 transakcija po sekundi, što značida na transakciju možete čekati i po nekoloo sati, u poređenju sa kešom (bez odugovlačenja) ili debitnim karticama (10 sekundi do 10 minuta). Visa i MasterCard procesuiraju hiljadu puta više transakcija po sekundi.

-Retko ko eksplicitno prima BTC, tako da ćete plaćati menjačnici na kursu u oba smera, i pritom čekati menjačnicu.

-Podložan je manipulacijama velikih igrača poput Ilona Maska i velikih banki koje su u zadnjih pet godina debelo uložile u kripto. Fiat je na milosti države i njenih građana, dok je BTC na milost privatnih investitora. Kome verujete više?

-SVE BTC transakcije su jsvne, ako neko zna koji novčanik je vaš lako zna i koliko para ste kada slali kome, dok fizičke novčanice nemaju taj problem.

-Vrednost i upotreljivost BTC ne garantuje niko, dok vrednost i upotrebljivost fiat valute barem donekle garantuje država. Na primer, Srbija garantuje da je dinar upotrebljiv jer zahteva da vodu, struju, poreze, namete i takse plaćaš u dinarima, a i javni sektor (10% čitavog stanovništva) isplaćuje isključivo u dinarima.

OP očigledno ima jako ostrašćenu ideološku perspektivu... Ja nisam stručnjak, ali je moj otac pisao naučne radove o blockchainu dok je bio na doktorskim studijama, još kad je pomisao o BTC vrednijem od sto dolada bila smešna, tako da znam nešto malo kroz priče sa njim. Uostalom, sve o čemu pričam lako je proveriti pomoću javnih podataka. Ono što OP piše je jednim delom tačno, ali su iznete samo one informacije koje idu u prilog BTC.

Kripto kao pobuna protiv fiata, centralnih banaka i vlada je imao ideološke korene kod anarhista na internetu devedestih, međutim od njihovih belih papira i špekulacija dobili smo nešto što je kao valuta beskorisno. BTC može biti investicija, ako su ljudi iskreni sa sobom, ali ideja o valuti je prevaziđena. Ako i neka kripto valuta drži do toga onda je to Monero koji bar ima anonimnost.

@BTCSRB: Ne ulazeći u sve iznete navode taksativno, ipak moram da prokomentarišem neke od nepreciznih ili netačnih navoda.

Transakcione naknade kod Bitkoina se ne zovu "gas fees" već "transaction fees". Kod keša nema takvih problema ali ga ne možete poslati putem komunikacionog kanala bez posrednika. To mora da ima svoju cenu pošto BTC majneri moraju da imaju neki podsticaj da uključe nečiju transakciju u blok koji je ograničene veličine. BTC "fee market" je najslobodnije tržište na svetu. Fiat novac nemate mogućnost da pošaljete na daljinu bez posrednika koji takođe naplaćuje nekada dosta skupe naknade.

Besmisleno je porediti blokčejn kao "settlement layer" sa Visom i Mastercardom koje ne služe za finalno poravnanje. Glavni Bitkoin blokčejn se može pre uporediti s SWIFT-om ili FedWire-om kod kojih je jednom poravnata transakcija nepovratna, a Mastercard/Visa sa BTC "Lightning Network-om" koji služi za brza i jeftina plaćanja. Otac je trebalo da Vas nauči o Lightning mreži, kako funkcioniše i da je sposobna da procesuira više miliona transakcija u sekundi. Lightning mreža takođe nudi veći nivo privatnosti od glavnog blokčejna ali puno manju sigurnost.

Ne bih se složio da je fiat na milosti isključivo države i građana, samo ću spomenuti Crnu sredu iz septembra 1992. godine i spekulativni napad na britansku funtu.

BTC transakcije su javne ali su pseudonimne što znači da je jako teško utvrditi identitet ukoliko adresa nije povezana sa identitetom korisnika. Generisanje BTC adrese ne zahteva nikakvu identifikaciju ("krvnu sliku") za razliku od otvaranja bankovnog računa. Može se generisati neograničen broj adresa i na razne načine prekinuti i zamaskirati veza transakcija između njih radi očuvanja privatnosti. Ponovo, fizičke novčanice ne možemo slati putem komunikacionog kanala bez posrednika, podložne su konfiskaciji, uništenju i obezvređivanju.

Upotrebljivost Bitkoina garantuje "open source" kod, energija, matematika i kriptografija. To su mnogo jače garancije nego obećanja bilo koje države koja su toliko puta u istoriji izigrale poverenje sopstvenog stanovništva - poput Jugoslavije devedesetih.

Ja sam BTC spomenuo kao potencijalno rešenje za (hiper)inflaciju tek u kraćem delu na kraju teksta, a od Vas i od ostalih komentatora sam dobio nesrazmeran odgovor usmeren na Bitkoin, a puno manje usmeren na navode iz najvećeg dela posta.

Tako ste i vi izneli isključivo informacije koje ne idu u prilog BTC-a, a potpuno ignorisali sve očigledne nedostatke fiat novca (kako u fizičkom, tako i u digitalnom obliku) koji su se i ispoljili tokom hiperinflacije devedesetih, a ispoljavaju se i dan-danas.

Svako dobro!

kutija_keksa: Zato su i „Gas fees” pod navodnicima.

Ne vidim zašto bi bilo dobro imati „slobodno tržište” kada se radi o kopačima.

Ali, čak i da je dobro imati slobodno tržište, morate primetiti da BTC kopanje nije tako slobodno. Postojanje ASIC mašina znači da se kopanje prevashodno isplati velikim igračima (ne mislim na likove sa 3 riser kartice u PC, nego na kineze sa skladištima teških preko milion u opremi). Takođe, te velike operacije organi vlasti mogu zaustaviti kad im se prohte (Kina).

Jako je teško izvući BTC anonimno bez gubitka kod menjača -- pojedinca ili non KYC institucije.

Što se upotrebljivosti BTC tiče, šta meni garantuje da ću imati na šta da potrošim BTC? To je ključno pitanje. A kasa Jugoslovenski fiat nije bio upotebljiv, vidim da Nemački jeste. Isto tako, mislim da će USD biti upotrebljiv dugo, a kada USD bude neupotrebljiv društvo će ionako biti u apokalipsi gde papir nije važan koliko i hrana, utočište, voda, radio, municija, lekovi i vatreno oružje.

Naravno da iznosim samo informacije koje proizilaze iz nedostataka, to je balans postu i komentarima. Da su ljudi samo blatili kripto moj komentar bi mnogo više ličio na originalni post nego na moj prošli komentar. Ja se sa mnogim tvrdnjama u postu slažem delimično ili potpuno, samo želim da pružim kontekst za tumačenje toga.

Ideološki su mi Cryptopunks potpuno zanimljivi, ali cinizam je opravdan kada se u obzir uzme priča. Ljudi su želeli da se odupru bankama, vladama, kontroli i prismotri. Izmislili su tehnologiju. Počeli su da koriste i popularizuju tu tehnologiju. U prostor su ušle banke i vlade, kupovanjem, prodajom i praćenjem samog tržišta (danas sve velike menjačnice imaju KYC procedure). Kao u matriksu, kontrolisana opozicija. Ok, ovo je lična teorija zavere u koju ni ja ne verujem u potpunosti.

Ako govorimo o crypto kao valuti mislim da je XMR mnogo bolja VALUTA od BTC, dok je mnogo gora investicija. Jednostavno se slažem sa političkim i ideološkim ciljevima pionira kripto valuta, ali smatram da su oni ogromnim delom iznevereni zbog ulaska banaka i država u celu priču, te njihova stara rešenja više ne rešavaju originalne probleme.

@BTCSRB: BTC kao neutralni novac je za svakoga, pa i za bankare i države. Ne možemo ih sprečiti da ga kupe na tržištu i stave ga u kakav god instrument, pa i ETF. Ne možemo ih sprečiti da ga konfiskuju od onih koji nisu dobro obezbedili svoje ključeve. Države su regulisale ono što su mogle, poput menjačnica, kroz AML/KYC procedure ali kakve to veze ima sa BTC-om? Na protokol kao protokol nisu mogle da utiču.

Ko želi i dalje može koristiti BTC kako je i prvobitno predviđeno - za p2p transakcije i skladištenje vrednosti u "self custody-u". Bitkoin je i dalje "bearer asset" otporan na cenzuru i konfiskaciju. Ne vidim da je taj pravac promenjen samo zato što su ušle banke i države. Možda nije u duhu Bitkoina da ga kupuju fondovi pa ga prodaju upakovanog u ETF. Najmanje je u duhu bitkoina da se nekome zabrani da ga kupuje.

Kako to mislite "ne vidite zašto bi bilo dobro imati „slobodno tržište” kada se radi o kopačima? Na decentralizaciji mininga se radi (StratumV2 protkol, Ocean pool...), a kineski primer je samo pokazatelj koliko je otporno: nakon zabrane raširilo se dodatno po svetu, a u Kini se i dalje nalazi 21% hešrejta. Majneri imaju veoma male margine profita zbog same prirode rudarenja i halvinga pa će bilo kakav "fck around" poput cenzure transakcija verovatno značiti bankrot.

Možemo do sutra pričati o XMR vs BTC i navešću puno razloga zašto XMR ne može i neće zaživeti kao novac, a pre svega je manjak decentralizacije (neograničena veličina blokčejna) i otpornost na državni napad - sve što Bitkoin ima. Kada je novac u pitanju pobednik nosi sve i tu je Monero već izgubio, dok će BTC poboljšanu privatnost obezbediti na ostalim nivoima, sidechainovima itd (Lightning, Liquid, Cashu, Fedimint, Ark i ko zna šta sve što još i ne postoji - nivo developmenta u Bitkoin prostoru je ogroman).

Dolar će uvek u nekom obliku biti upotrebljiv ali ne znači da će zauvek ostati svetska rezervna valuta, kao što i danas postoji funta ali odavno nije više ono što je bila na vrhuncu Britanske imperije.

kutija_keksa: Pa ti protokoli sprečavaju pljude da anonimno kupe BTC.

Mislim, BTC realno ima neku primenu, ali ja ga danas npr. imam čisto kao neku malu investicijicu, i to još od doba kad je kopanje sa 2 grafičke u kućnom PC bilo isplativo po skupoj struji. Ali BTC prosto nije dobra alternativa fizičkom novcu na nivou države zbog volatilnosti i manjka kontrole. Jedna ogromna poluga države je puštanje u promet novog novca, i tako se kontroliše inflacija, pored menjanja kamatnih stopa. Bez mogućnosti štampe gubi se i taj faktor kontrole. A inflacija od 2-3% godišnje je zdrava, dok je za ekonomiju deflacija (kojoj je BTC bar delimično sklon) haos, jer smanjuje ekonomsku aktivnost i investicije...

Što se tiče državnog napada na XMR, misliš na to kako jedna država može da realistično sprovede 51% napad?

XMR nije vrhovna valuta ali meni se sviđa kako za njega nema ASIC mašina, kako je anoniman u smislu da ne možeš lako da provališ ko kome koliko i kada šalje šta... Mislim da će XMR sigurno u toj privacy niši zameniti neka druga valuta kroz 10-15 godina koja ima bolji algoritam i tehnologiju...

Dobra dosetka za veličinu blockchaina, ali ona je trenutno 160GB cela / 50 GB pruned, tako nešto. Sve dok nije preko 10TB (100x) veća može je pohraniti najveći hard disk namenjen „običnim ljudima”, a kad se dođe do tad verovatno će i cene tih diskova biti pristupačnije nego danas. Sa druge strane, agresivan pruning je takođe opcija. A da ne govorimo o sidechainovima koji takođe postoje za XMR.

Da, to za dolar je i moja poenta, nekako će biti upotrebljiv uvek, dok je kripto neupotrebljiv bez neta, a i nema mnogo šta da se kupi kriptom u poređenju sa fiatom. I

@BTCSRB: Ima bezbroj načina da se nabavi non-KYC Bitkoin: coinjoin, coinmixing, rudarenje u non-KYC pulu, nabavka nekog drugog kripta putem KYC menjačnice pa "trustless atomic swap" za BTC, nabavka KYC BTC-a putem Lightning-a pa "submarine swap" on-chain, zatim nabavka bilo kog KYC kripta ili Lightning ili on-chain BTC-a pa swap na sidechain Liquid BTC gde su transakcije tajne slično XMR-u i nazad swap na on-chain. Naravno i stara narodska razmena na ulici. XMR se isto može koristiti za svrhu nabavke non-KYC Bitkoina. U svim ovim slučajevima se adrese koje su krajnje destinacije tih sredstava ne mogu ili jako teško povezati sa KYC identitetom korisnika. Više na: kycnot.me

Diskusija o tome da li je zdrava i potrebna inflacija i da li je uopšte potreban državni intervencionizam u ekonomiji je stara diskusija između Kejnzijanske i Austrijske ekonomske škole. Po meni svaka inflacija je pljačka. Da ne govorimo da centralni bankari ne snose nikakvu odgovornost za gubitak kontrole nad inflacijom koji se meri u stotinama procenata "omaška" jer kada je ciljana inflacija 2%, a imamo inflaciju od 10% to je onda promašaj od 500%. A svi vodeći centralni bankari su i dalje na svojim funkcijama od početka inflacije negde 2020. godine iako su izneverili sva očekivanja. Nisu izabrani od strane naroda i nemoguće ih je smeniti od strane naroda, a utiču na živote svih!

Usled tehnološkog napretka i rasta produktivnosti, prirodno stanje slobodnog tržišta je pad cena, a ne njihov konstantan rast kroz inflaciju. Ne postoji nikakva "poželjna" ili "neophodna" inflacija, svaka "ciljana" inflacija je pljačka koji onemogućava populaciju da uživa u plodovima sopstvene produktivnosti u obliku nižih cena svih roba i usluga. Bitkoin zbog svoje fiksne ponude novca u opticaju (21 milion novčića = apsolutna digitalna oskudnost) nameće ovu disciplinu slobodnog tržišta i tehnološkog napretka. Dok je postojeći dužnički fiat sistem dizajniran da krade plodove produktivnosti, Bitkoin omogućava populaciji da ih zadrži u obliku nižih cena.

Kada nema rasta cena, inflacija je 0% i cene su stabilne. Krađa i tada postoji, jer cene prirodno padaju zbog povećanja efikasnosti proizvodnje/usluga, gde bi se tada veca količina robe/usluga, takmičila za istu (fiksnu) količinu novča od 21M BTC-a.

Kakav je ishod ove diskusije nije bitno, bitno je da sada svako ima slobodu izbora kakav novac želi da koristi a ne da bude prisiljen da koristi isključivo inflatorni novac. Ako se neko ne slaže sa modernom monetarnom teorijom, sada ima alternativu koju nekada nije imao (zlato je odavno izgubilo bitku sa MMT) pre postojanja Bitkoina.

kutija_keksa: Neki od ovih non kyc nacina su mi vec bili poznati, neki nisu, ovo je bas informativan komentar.

A što je inflacija pljačka? Bez obzira na inflaciju, broj novčanica u novčaniku ostaje isti, to što se one sada mogu zameniti za manje robe je druga priča. Da li je onda i zlato pljačka, jer neko kupi, na primer, 100g zlata danas, a sutra na tržištu cena zlata padne? Da li je onda pljačka i BTC, jer i danas i kad je BTC bio na vrhuncu cene imam isti broj satoshija, samo je danas njihova vrednost manja?

Ne vidim zašto bi centralni bankari snosili odgovornost zbog inflacije. Oni ugrobo imaju dve poluge za kontrolu inflacije: kamatne stope i štampanje novca. U realnosti na inflaciju utiče mnogo faktora na koje centralna banka nema uticaj, niti koje može da predvidi: pandemije, ratovi, državni budžeti i zaduživanja, trgovina u datoj valuti (i izvoz i uvoz), porast i pad produktivnosti... Oni imaju donekle uticaj, ali nisu svemoćni.

Što se tiče izbora, ovo već zalazi u politiku a ne u finansije, ali ni direktor pošte, ni direktor EPS, ni direktor vodovoda nisu birani na izborima na kojima glasaju svi, a utiču na živote svih!

Ne verujem u kripto kao spasioce kapitalizma ili pojedinca. Ovo je sada više politički, ali zaista mislim da u kapitalizmu prosečna osoba nema slobode, a da je kripto u najbolju ruku jedna mala stavka koja omogućava skladištenje stečenog kapitala (ovo se dobija ako prihvatimo sve kripto pozitivne teze), ali ne rešava problem radnika koji čine 95% društva i doprinose 99% vrednosti a kapitala kontrolišu višestruko manje.

Otkud znam, ono, da rezimiram: kripto je koristan alat koji još nije dostigao svoj vrhunac, ali neće nešto mnogo promeniti svet. To je neko moje viđenje.

@BTCSRB: Kako nije pljačka? Broj novčanica u novčaniku ostaje isti ali ukupan broj novca u opticaju se uvećava i tako obezvređuje tvoje novčanice. Inače, znaš vrlo dobro da fizički keš čini manje od 10% ukupnog novca u opticaju, a ostalo je digitalno. Dakle "money supply" se uvećava pritiskom na dugme tastature računara u FED/ECB/NBS... Neko stvara novac ni iz čega za koji svi moramo da radimo trošeći svoje dragoceno i ograničeno vreme na ovom svetu. Tako nam efektivno krade vreme pošto tvoj radni sat iz prošlosti konstantno može da kupi manje roba i usluga u budućnosti, a zbog tehnološkog napretka i rasta produktivnosti bi realno cene trebaju da budu niže vremenom

Kako možeš da porediš fiat, zlato i BTC u tom smislu? Vrednost fiata prevashodno smanjuje ljudska manipulacija sa strane ponude koja se uvek uvećava, dok je potražnja permanentno rastuća zbog zakona o "legal tenderu" i rasta privrede i broja stanovnika. Ovo sa BTC je strana potražnje koju reguliše slobodno tržište dok ukupna ponuda nije podložna ljudskoj manipulaciji. Dugoročno, vrednost zlata i BTC raste sa rastućom potražnjom jer nema manipulacije ponude.

Centralni bankari će optužiti sve druge faktore da bi skrenuli pažnju sa svoje odgovornosti za inflaciju, a za ratove se može reći da su čak i saučesnici pošto tokovi novca mogu utvrditi veoma zanimljivu vezu između njih i vojno-industrijskog kompleksa. Na stranu to, dolarska monetarna masa je samo između februara i aprila 2020. uvećana za 1.39 biliona/triliona što je više nego ukupna monetarna masa iz 2008-09 krize. U krizi 2008-09 su od septembra 2008. do januara 2009. naštampali 803 milijarde i tako uvećali monetarnu masu za 88% sa 909 milijardi na 1712 milijardi - to znači da su 4 meseca naštampali skoro isto novca kao tokom celih 95 prethodnig godina sopstvenog postojanja Federalnih rezervi. Te 2020. su i potpuno ukinuli obavezne rezerve u komercijalnim bankama.

ECB je naštampala 1T evra "zbog kovida". A kao naštampali su jer je bila zatvorena celokupna privreda, pa što ste tako agresivno zatvarali privredu - trebalo je da pustite ljude da rade a ne da se igrate Mao Ce Tunga. I uprkos nezapamćenom štampanju ti isti centralni bankari su nazivali inflaciju "prolaznom" - dakle ni zrnce odgovornosti.

Ako u kapitalizmu prosečna osoba nema slobode, šta reći za komunizam gde ne da nema slobode nego nema ni života pošto su komunistički režimi pobili na desetine miliona ljudi?

Na hipotetičkom BTC standardu zbog fiksne količine novca u opticaju bi se popravio položaj radnika jer kapitalisti ne mogu da beskonačno uvećavaju svoj BTC kapital i kupovna moć i radnika i kapitalista bi procentualno podjednako rasla i običan radnik bi imao mnogo bolje šanse da i sam postane kapitalista nego danas. Imao bi mogućnost da štedi od svoje plate jer mu novac ne bi gubio vrednost i u nekom trenutku bi iz svoje štednje finansirao neki biznis, a ne zaduživanjem. Tako bi se ravnomernije rasporedilo društveno bogatstvo ali ne centralnim planiranjem nego kroz slobodno tržište.

O que é Cwtch? Cwtch (/kʊtʃ/ - uma palavra galesa que pode ser traduzida aproximadamente como “um abraço que cria um lugar seguro”) é um protocolo de mensagens multipartidário descentralizado, que preserva a privacidade, que pode ser usado para construir aplicativos resistentes a metadados.

Como posso pronunciar Cwtch? Como "kutch", para rimar com "butch".

Descentralizado e Aberto : Não existe “serviço Cwtch” ou “rede Cwtch”. Os participantes do Cwtch podem hospedar seus próprios espaços seguros ou emprestar sua infraestrutura para outras pessoas que buscam um espaço seguro. O protocolo Cwtch é aberto e qualquer pessoa é livre para criar bots, serviços e interfaces de usuário e integrar e interagir com o Cwtch.

Preservação de privacidade : toda a comunicação no Cwtch é criptografada de ponta a ponta e ocorre nos serviços cebola Tor v3.

Resistente a metadados : O Cwtch foi projetado de forma que nenhuma informação seja trocada ou disponibilizada a ninguém sem seu consentimento explícito, incluindo mensagens durante a transmissão e metadados de protocolo

Uma breve história do bate-papo resistente a metadados Nos últimos anos, a conscientização pública sobre a necessidade e os benefícios das soluções criptografadas de ponta a ponta aumentou com aplicativos como Signal , Whatsapp e Wire. que agora fornecem aos usuários comunicações seguras.

No entanto, essas ferramentas exigem vários níveis de exposição de metadados para funcionar, e muitos desses metadados podem ser usados ​​para obter detalhes sobre como e por que uma pessoa está usando uma ferramenta para se comunicar.

Uma ferramenta que buscou reduzir metadados é o Ricochet lançado pela primeira vez em 2014. Ricochet usou os serviços cebola Tor v2 para fornecer comunicação criptografada segura de ponta a ponta e para proteger os metadados das comunicações.

Não havia servidores centralizados que auxiliassem no roteamento das conversas do Ricochet. Ninguém além das partes envolvidas em uma conversa poderia saber que tal conversa está ocorrendo.

Ricochet tinha limitações; não havia suporte para vários dispositivos, nem existe um mecanismo para suportar a comunicação em grupo ou para um usuário enviar mensagens enquanto um contato está offline.

Isto tornou a adoção do Ricochet uma proposta difícil; mesmo aqueles em ambientes que seriam melhor atendidos pela resistência aos metadados, sem saber que ela existe.

Além disso, qualquer solução para comunicação descentralizada e resistente a metadados enfrenta problemas fundamentais quando se trata de eficiência, privacidade e segurança de grupo conforme definido pelo consenso e consistência da transcrição.

Alternativas modernas ao Ricochet incluem Briar , Zbay e Ricochet Refresh - cada ferramenta procura otimizar para um conjunto diferente de compensações, por exemplo, Briar procura permitir que as pessoas se comuniquem mesmo quando a infraestrutura de rede subjacente está inoperante, ao mesmo tempo que fornece resistência à vigilância de metadados.

O projeto Cwtch começou em 2017 como um protocolo de extensão para Ricochet, fornecendo conversas em grupo por meio de servidores não confiáveis, com o objetivo de permitir aplicativos descentralizados e resistentes a metadados como listas compartilhadas e quadros de avisos.

Uma versão alfa do Cwtch foi lançada em fevereiro de 2019 e, desde então, a equipe do Cwtch dirigida pela OPEN PRIVACY RESEARCH SOCIETY conduziu pesquisa e desenvolvimento em cwtch e nos protocolos, bibliotecas e espaços de problemas subjacentes.

Modelo de Risco.

Sabe-se que os metadados de comunicações são explorados por vários adversários para minar a segurança dos sistemas, para rastrear vítimas e para realizar análises de redes sociais em grande escala para alimentar a vigilância em massa. As ferramentas resistentes a metadados estão em sua infância e faltam pesquisas sobre a construção e a experiência do usuário de tais ferramentas.

https://nostrcheck.me/media/public/nostrcheck.me_9475702740746681051707662826.webp

O Cwtch foi originalmente concebido como uma extensão do protocolo Ricochet resistente a metadados para suportar comunicações assíncronas de grupos multiponto por meio do uso de infraestrutura anônima, descartável e não confiável.

Desde então, o Cwtch evoluiu para um protocolo próprio. Esta seção descreverá os vários riscos conhecidos que o Cwtch tenta mitigar e será fortemente referenciado no restante do documento ao discutir os vários subcomponentes da Arquitetura Cwtch.

Modelo de ameaça.

É importante identificar e compreender que os metadados são omnipresentes nos protocolos de comunicação; é de facto necessário que tais protocolos funcionem de forma eficiente e em escala. No entanto, as informações que são úteis para facilitar peers e servidores também são altamente relevantes para adversários que desejam explorar tais informações.

Para a definição do nosso problema, assumiremos que o conteúdo de uma comunicação é criptografado de tal forma que um adversário é praticamente incapaz de quebrá-lo veja tapir e cwtch para detalhes sobre a criptografia que usamos, e como tal nos concentraremos em o contexto para os metadados de comunicação.

Procuramos proteger os seguintes contextos de comunicação:

• Quem está envolvido em uma comunicação? Pode ser possível identificar pessoas ou simplesmente identificadores de dispositivos ou redes. Por exemplo, “esta comunicação envolve Alice, uma jornalista, e Bob, um funcionário público”.

• Onde estão os participantes da conversa? Por exemplo, “durante esta comunicação, Alice estava na França e Bob estava no Canadá”.

• Quando ocorreu uma conversa? O momento e a duração da comunicação podem revelar muito sobre a natureza de uma chamada, por exemplo, “Bob, um funcionário público, conversou com Alice ao telefone por uma hora ontem à noite. Esta é a primeira vez que eles se comunicam.” *Como a conversa foi mediada? O fato de uma conversa ter ocorrido por meio de um e-mail criptografado ou não criptografado pode fornecer informações úteis. Por exemplo, “Alice enviou um e-mail criptografado para Bob ontem, enquanto eles normalmente enviam apenas e-mails de texto simples um para o outro”.

• Sobre o que é a conversa? Mesmo que o conteúdo da comunicação seja criptografado, às vezes é possível derivar um contexto provável de uma conversa sem saber exatamente o que é dito, por exemplo, “uma pessoa ligou para uma pizzaria na hora do jantar” ou “alguém ligou para um número conhecido de linha direta de suicídio na hora do jantar”. 3 horas da manhã."

Além das conversas individuais, também procuramos defender-nos contra ataques de correlação de contexto, através dos quais múltiplas conversas são analisadas para obter informações de nível superior:

• Relacionamentos: Descobrir relações sociais entre um par de entidades analisando a frequência e a duração de suas comunicações durante um período de tempo. Por exemplo, Carol e Eve ligam uma para a outra todos os dias durante várias horas seguidas.

• Cliques: Descobrir relações sociais entre um grupo de entidades que interagem entre si. Por exemplo, Alice, Bob e Eva se comunicam entre si.

• Grupos vagamente conectados e indivíduos-ponte: descobrir grupos que se comunicam entre si através de intermediários, analisando cadeias de comunicação (por exemplo, toda vez que Alice fala com Bob, ela fala com Carol quase imediatamente depois; Bob e Carol nunca se comunicam).

• Padrão de Vida: Descobrir quais comunicações são cíclicas e previsíveis. Por exemplo, Alice liga para Eve toda segunda-feira à noite por cerca de uma hora. Ataques Ativos

Ataques de deturpação.

O Cwtch não fornece registro global de nomes de exibição e, como tal, as pessoas que usam o Cwtch são mais vulneráveis ​​a ataques baseados em declarações falsas, ou seja, pessoas que fingem ser outras pessoas:

O fluxo básico de um desses ataques é o seguinte, embora também existam outros fluxos:

•Alice tem um amigo chamado Bob e outro chamado Eve

• Eve descobre que Alice tem um amigo chamado Bob

• Eve cria milhares de novas contas para encontrar uma que tenha uma imagem/chave pública semelhante à de Bob (não será idêntica, mas pode enganar alguém por alguns minutos)

• Eve chama essa nova conta de "Eve New Account" e adiciona Alice como amiga.

• Eve então muda seu nome em "Eve New Account" para "Bob"

• Alice envia mensagens destinadas a "Bob" para a conta falsa de Bob de Eve Como os ataques de declarações falsas são inerentemente uma questão de confiança e verificação, a única maneira absoluta de evitá-los é os usuários validarem absolutamente a chave pública. Obviamente, isso não é o ideal e, em muitos casos, simplesmente não acontecerá .

Como tal, pretendemos fornecer algumas dicas de experiência do usuário na interface do usuário para orientar as pessoas na tomada de decisões sobre confiar em contas e/ou distinguir contas que possam estar tentando se representar como outros usuários.

Uma nota sobre ataques físicos A Cwtch não considera ataques que exijam acesso físico (ou equivalente) à máquina do usuário como praticamente defensáveis. No entanto, no interesse de uma boa engenharia de segurança, ao longo deste documento ainda nos referiremos a ataques ou condições que exigem tal privilégio e indicaremos onde quaisquer mitigações que implementámos falharão.

Um perfil Cwtch.

Os usuários podem criar um ou mais perfis Cwtch. Cada perfil gera um par de chaves ed25519 aleatório compatível com Tor.

Além do material criptográfico, um perfil também contém uma lista de Contatos (outras chaves públicas do perfil Cwtch + dados associados sobre esse perfil, como apelido e (opcionalmente) mensagens históricas), uma lista de Grupos (contendo o material criptográfico do grupo, além de outros dados associados, como apelido do grupo e mensagens históricas).

Conversões entre duas partes: ponto a ponto

https://nostrcheck.me/media/public/nostrcheck.me_2186338207587396891707662879.webp

Para que duas partes participem de uma conversa ponto a ponto, ambas devem estar on-line, mas apenas uma precisa estar acessível por meio do serviço Onion. Por uma questão de clareza, muitas vezes rotulamos uma parte como “ponto de entrada” (aquele que hospeda o serviço cebola) e a outra parte como “ponto de saída” (aquele que se conecta ao serviço cebola).

Após a conexão, ambas as partes adotam um protocolo de autenticação que:

• Afirma que cada parte tem acesso à chave privada associada à sua identidade pública.

• Gera uma chave de sessão efêmera usada para criptografar todas as comunicações futuras durante a sessão.

Esta troca (documentada com mais detalhes no protocolo de autenticação ) é negável offline , ou seja, é possível para qualquer parte falsificar transcrições desta troca de protocolo após o fato e, como tal - após o fato - é impossível provar definitivamente que a troca aconteceu de forma alguma.

Após o protocolo de autenticação, as duas partes podem trocar mensagens livremente.

Conversas em Grupo e Comunicação Ponto a Servidor

Ao iniciar uma conversa em grupo, é gerada uma chave aleatória para o grupo, conhecida como Group Key. Todas as comunicações do grupo são criptografadas usando esta chave. Além disso, o criador do grupo escolhe um servidor Cwtch para hospedar o grupo. Um convite é gerado, incluindo o Group Key, o servidor do grupo e a chave do grupo, para ser enviado aos potenciais membros.

Para enviar uma mensagem ao grupo, um perfil se conecta ao servidor do grupo e criptografa a mensagem usando a Group Key, gerando também uma assinatura sobre o Group ID, o servidor do grupo e a mensagem. Para receber mensagens do grupo, um perfil se conecta ao servidor e baixa as mensagens, tentando descriptografá-las usando a Group Key e verificando a assinatura.

Detalhamento do Ecossistema de Componentes

O Cwtch é composto por várias bibliotecas de componentes menores, cada uma desempenhando um papel específico. Algumas dessas bibliotecas incluem:

• abertoprivacidade/conectividade: Abstração de rede ACN, atualmente suportando apenas Tor.
• cwtch.im/tapir: Biblioteca para construção de aplicativos p2p em sistemas de comunicação anônimos.
• cwtch.im/cwtch: Biblioteca principal para implementação do protocolo/sistema Cwtch.
• cwtch.im/libcwtch-go: Fornece ligações C para Cwtch para uso em implementações de UI.

TAPIR: Uma Visão Detalhada

Projetado para substituir os antigos canais de ricochete baseados em protobuf, o Tapir fornece uma estrutura para a construção de aplicativos anônimos.

Está dividido em várias camadas:

• Identidade - Um par de chaves ed25519, necessário para estabelecer um serviço cebola Tor v3 e usado para manter uma identidade criptográfica consistente para um par.

• Conexões – O protocolo de rede bruto que conecta dois pares. Até agora, as conexões são definidas apenas através do Tor v3 Onion Services.

• Aplicativos - As diversas lógicas que permitem um determinado fluxo de informações em uma conexão. Os exemplos incluem transcrições criptográficas compartilhadas, autenticação, proteção contra spam e serviços baseados em tokens. Os aplicativos fornecem recursos que podem ser referenciados por outros aplicativos para determinar se um determinado peer tem a capacidade de usar um determinado aplicativo hospedado.

• Pilhas de aplicativos - Um mecanismo para conectar mais de um aplicativo, por exemplo, a autenticação depende de uma transcrição criptográfica compartilhada e o aplicativo peer cwtch principal é baseado no aplicativo de autenticação.

Identidade.

Um par de chaves ed25519, necessário para estabelecer um serviço cebola Tor v3 e usado para manter uma identidade criptográfica consistente para um peer.

InitializeIdentity - de um par de chaves conhecido e persistente:i,I

InitializeEphemeralIdentity - de um par de chaves aleatório: ie,Ie

Aplicativos de transcrição.

Inicializa uma transcrição criptográfica baseada em Merlin que pode ser usada como base de protocolos baseados em compromisso de nível superior

O aplicativo de transcrição entrará em pânico se um aplicativo tentar substituir uma transcrição existente por uma nova (aplicando a regra de que uma sessão é baseada em uma e apenas uma transcrição).

Merlin é uma construção de transcrição baseada em STROBE para provas de conhecimento zero. Ele automatiza a transformação Fiat-Shamir, para que, usando Merlin, protocolos não interativos possam ser implementados como se fossem interativos.

Isto é significativamente mais fácil e menos sujeito a erros do que realizar a transformação manualmente e, além disso, também fornece suporte natural para:

• protocolos multi-round com fases alternadas de commit e desafio;

• separação natural de domínios, garantindo que os desafios estejam vinculados às afirmações a serem provadas;

• enquadramento automático de mensagens, evitando codificação ambígua de dados de compromisso;

• e composição do protocolo, usando uma transcrição comum para vários protocolos.

Finalmente, o Merlin também fornece um gerador de números aleatórios baseado em transcrição como defesa profunda contra ataques de entropia ruim (como reutilização de nonce ou preconceito em muitas provas). Este RNG fornece aleatoriedade sintética derivada de toda a transcrição pública, bem como dos dados da testemunha do provador e uma entrada auxiliar de um RNG externo.

Conectividade Cwtch faz uso do Tor Onion Services (v3) para todas as comunicações entre nós.

Fornecemos o pacote openprivacy/connectivity para gerenciar o daemon Tor e configurar e desmontar serviços cebola através do Tor.

Criptografia e armazenamento de perfil.

Os perfis são armazenados localmente no disco e criptografados usando uma chave derivada de uma senha conhecida pelo usuário (via pbkdf2).

Observe que, uma vez criptografado e armazenado em disco, a única maneira de recuperar um perfil é recuperando a senha - como tal, não é possível fornecer uma lista completa de perfis aos quais um usuário pode ter acesso até inserir uma senha.

Perfis não criptografados e a senha padrão Para lidar com perfis "não criptografados" (ou seja, que não exigem senha para serem abertos), atualmente criamos um perfil com uma senha codificada de fato .

Isso não é o ideal, preferiríamos confiar no material de chave fornecido pelo sistema operacional, de modo que o perfil fosse vinculado a um dispositivo específico, mas esses recursos são atualmente uma colcha de retalhos - também notamos, ao criar um perfil não criptografado, pessoas que usam Cwtch estão explicitamente optando pelo risco de que alguém com acesso ao sistema de arquivos possa descriptografar seu perfil.

Vulnerabilidades Relacionadas a Imagens e Entrada de Dados

Imagens Maliciosas

O Cwtch enfrenta desafios na renderização de imagens, com o Flutter utilizando Skia, embora o código subjacente não seja totalmente seguro para a memória.

Realizamos testes de fuzzing nos componentes Cwtch e encontramos um bug de travamento causado por um arquivo GIF malformado, levando a falhas no kernel. Para mitigar isso, adotamos a política de sempre habilitar cacheWidth e/ou cacheHeight máximo para widgets de imagem.

Identificamos o risco de imagens maliciosas serem renderizadas de forma diferente em diferentes plataformas, como evidenciado por um bug no analisador PNG da Apple.

Riscos de Entrada de Dados

Um risco significativo é a interceptação de conteúdo ou metadados por meio de um Input Method Editor (IME) em dispositivos móveis. Mesmo aplicativos IME padrão podem expor dados por meio de sincronização na nuvem, tradução online ou dicionários pessoais.

Implementamos medidas de mitigação, como enableIMEPersonalizedLearning: false no Cwtch 1.2, mas a solução completa requer ações em nível de sistema operacional e é um desafio contínuo para a segurança móvel.

Servidor Cwtch.

O objetivo do protocolo Cwtch é permitir a comunicação em grupo através de infraestrutura não confiável .

Ao contrário dos esquemas baseados em retransmissão, onde os grupos atribuem um líder, um conjunto de líderes ou um servidor confiável de terceiros para garantir que cada membro do grupo possa enviar e receber mensagens em tempo hábil (mesmo que os membros estejam offline) - infraestrutura não confiável tem o objetivo de realizar essas propriedades sem a suposição de confiança.

O artigo original do Cwtch definia um conjunto de propriedades que se esperava que os servidores Cwtch fornecessem:

• O Cwtch Server pode ser usado por vários grupos ou apenas um.

• Um servidor Cwtch, sem a colaboração de um membro do grupo, nunca deve aprender a identidade dos participantes de um grupo.

• Um servidor Cwtch nunca deve aprender o conteúdo de qualquer comunicação.

• Um servidor Cwtch nunca deve ser capaz de distinguir mensagens como pertencentes a um grupo específico. Observamos aqui que essas propriedades são um superconjunto dos objetivos de design das estruturas de Recuperação de Informações Privadas.

Melhorias na Eficiência e Segurança

Eficiência do Protocolo

Atualmente, apenas um protocolo conhecido, o PIR ingênuo, atende às propriedades desejadas para garantir a privacidade na comunicação do grupo Cwtch. Este método tem um impacto direto na eficiência da largura de banda, especialmente para usuários em dispositivos móveis. Em resposta a isso, estamos ativamente desenvolvendo novos protocolos que permitem negociar garantias de privacidade e eficiência de maneiras diversas.

Os servidores, no momento desta escrita, permitem o download completo de todas as mensagens armazenadas, bem como uma solicitação para baixar mensagens específicas a partir de uma determinada mensagem. Quando os pares ingressam em um grupo em um novo servidor, eles baixam todas as mensagens do servidor inicialmente e, posteriormente, apenas as mensagens novas.

Mitigação de Análise de Metadados

Essa abordagem permite uma análise moderada de metadados, pois o servidor pode enviar novas mensagens para cada perfil suspeito exclusivo e usar essas assinaturas de mensagens exclusivas para rastrear sessões ao longo do tempo. Essa preocupação é mitigada por dois fatores:

1. Os perfis podem atualizar suas conexões a qualquer momento, resultando em uma nova sessão do servidor.
2. Os perfis podem ser "ressincronizados" de um servidor a qualquer momento, resultando em uma nova chamada para baixar todas as mensagens. Isso é comumente usado para buscar mensagens antigas de um grupo.

Embora essas medidas imponham limites ao que o servidor pode inferir, ainda não podemos garantir resistência total aos metadados. Para soluções futuras para esse problema, consulte Niwl.

Proteção contra Pares Maliciosos

Os servidores enfrentam o risco de spam gerado por pares, representando uma ameaça significativa à eficácia do sistema Cwtch. Embora tenhamos implementado um mecanismo de proteção contra spam no protótipo do Cwtch, exigindo que os pares realizem alguma prova de trabalho especificada pelo servidor, reconhecemos que essa não é uma solução robusta na presença de um adversário determinado com recursos significativos.

Pacotes de Chaves

Os servidores Cwtch se identificam por meio de pacotes de chaves assinados, contendo uma lista de chaves necessárias para garantir a segurança e resistência aos metadados na comunicação do grupo Cwtch. Esses pacotes de chaves geralmente incluem três chaves: uma chave pública do serviço Tor v3 Onion para o Token Board, uma chave pública do Tor v3 Onion Service para o Token Service e uma chave pública do Privacy Pass.

Para verificar os pacotes de chaves, os perfis que os importam do servidor utilizam o algoritmo trust-on-first-use (TOFU), verificando a assinatura anexada e a existência de todos os tipos de chave. Se o perfil já tiver importado o pacote de chaves do servidor anteriormente, todas as chaves são consideradas iguais.

Configuração prévia do aplicativo para ativar o Relé do Cwtch.

No Android, a hospedagem de servidor não está habilitada, pois essa opção não está disponível devido às limitações dos dispositivos Android. Essa funcionalidade está reservada apenas para servidores hospedados em desktops.

No Android, a única forma direta de importar uma chave de servidor é através do grupo de teste Cwtch, garantindo assim acesso ao servidor Cwtch.

Primeiro passo é Habilitar a opção de grupo no Cwtch que está em fase de testes. Clique na opção no canto superior direito da tela de configuração e pressione o botão para acessar as configurações do Cwtch.

Você pode alterar o idioma para Português do Brasil.Depois, role para baixo e selecione a opção para ativar os experimentos. Em seguida, ative a opção para habilitar o chat em grupo e a pré-visualização de imagens e fotos de perfil, permitindo que você troque sua foto de perfil.

https://pomf2.lain.la/f/eprhj0u3.mp4

Próximo passo é Criar um perfil.

Pressione o + botão de ação no canto inferior direito e selecione "Novo perfil" ou aberta no botão + adicionar novo perfil.

• Selecione um nome de exibição

• Selecione se deseja proteger

este perfil e salvo localmente com criptografia forte: Senha: sua conta está protegida de outras pessoas que possam usar este dispositivo

Sem senha: qualquer pessoa que tenha acesso a este dispositivo poderá acessar este perfil.

Preencha sua senha e digite-a novamente

Os perfis são armazenados localmente no disco e criptografados usando uma chave derivada de uma senha conhecida pelo usuário (via pbkdf2).

Observe que, uma vez criptografado e armazenado em disco, a única maneira de recuperar um perfil é recuperando a chave da senha - como tal, não é possível fornecer uma lista completa de perfis aos quais um usuário pode ter acesso até inserir um senha.

O próximo passo é adicionar o FuzzBot, que é um bot de testes e de desenvolvimento.

Contato do FuzzBot: 4y2hxlxqzautabituedksnh2ulcgm2coqbure6wvfpg4gi2ci25ta5ad.

Ao enviar o comando "testgroup-invite" para o FuzzBot, você receberá um convite para entrar no Grupo Cwtch Test. Ao ingressar no grupo, você será automaticamente conectado ao servidor Cwtch. Você pode optar por sair do grupo a qualquer momento ou ficar para conversar e tirar dúvidas sobre o aplicativo e outros assuntos. Depois, você pode configurar seu próprio servidor Cwtch, o que é altamente recomendável. https://pomf2.lain.la/f/x4pm8hm8.mp4

Agora você pode utilizar o aplicativo normalmente. Algumas observações que notei: se houver demora na conexão com outra pessoa, ambas devem estar online. Se ainda assim a conexão não for estabelecida, basta clicar no ícone de reset do Tor para restabelecer a conexão com a outra pessoa.

Uma introdução aos perfis Cwtch.

Com Cwtch você pode criar um ou mais perfis . Cada perfil gera um par de chaves ed25519 aleatório compatível com a Rede Tor.

Este é o identificador que você pode fornecer às pessoas e que elas podem usar para entrar em contato com você via Cwtch.

Cwtch permite criar e gerenciar vários perfis separados. Cada perfil está associado a um par de chaves diferente que inicia um serviço cebola diferente.

Gerenciar Na inicialização, o Cwtch abrirá a tela Gerenciar Perfis. Nessa tela você pode:

• Crie um novo perfil.
• Desbloquear perfis.
• Criptografados existentes.
• Gerenciar perfis carregados.
• Alterando o nome de exibição de um perfil.
• Alterando a senha de um perfil Excluindo um perfil.
• Alterando uma imagem de perfil.

Backup ou exportação de um perfil.

Na tela de gerenciamento de perfil:

1. Selecione o lápis ao lado do perfil que você deseja editar

2. Role para baixo até a parte inferior da tela.

3. Selecione "Exportar perfil"

4. Escolha um local e um nome de arquivo.

5.confirme.

Uma vez confirmado, o Cwtch colocará uma cópia do perfil no local indicado. Este arquivo é criptografado no mesmo nível do perfil.

Este arquivo pode ser importado para outra instância do Cwtch em qualquer dispositivo.

Importando um perfil.

1. Pressione o +botão de ação no canto inferior direito e selecione "Importar perfil"

2. Selecione um arquivo de perfil Cwtch exportado para importar

3. Digite a senha associada ao perfil e confirme.

Uma vez confirmado, o Cwtch tentará descriptografar o arquivo fornecido usando uma chave derivada da senha fornecida. Se for bem-sucedido, o perfil aparecerá na tela Gerenciamento de perfil e estará pronto para uso.

OBSERVAÇÃO Embora um perfil possa ser importado para vários dispositivos, atualmente apenas uma versão de um perfil pode ser usada em todos os dispositivos ao mesmo tempo. As tentativas de usar o mesmo perfil em vários dispositivos podem resultar em problemas de disponibilidade e falhas de mensagens.

Qual é a diferença entre uma conexão ponto a ponto e um grupo cwtch?

As conexões ponto a ponto Cwtch permitem que 2 pessoas troquem mensagens diretamente. As conexões ponto a ponto nos bastidores usam serviços cebola Tor v3 para fornecer uma conexão criptografada e resistente a metadados. Devido a esta conexão direta, ambas as partes precisam estar online ao mesmo tempo para trocar mensagens.

Os Grupos Cwtch permitem que várias partes participem de uma única conversa usando um servidor não confiável (que pode ser fornecido por terceiros ou auto-hospedado). Os operadores de servidores não conseguem saber quantas pessoas estão em um grupo ou o que está sendo discutido. Se vários grupos estiverem hospedados em um único servidor, o servidor não conseguirá saber quais mensagens pertencem a qual grupo sem a conivência de um membro do grupo. Ao contrário das conversas entre pares, as conversas em grupo podem ser conduzidas de forma assíncrona, para que todos num grupo não precisem estar online ao mesmo tempo.

Por que os grupos cwtch são experimentais? Mensagens em grupo resistentes a metadados ainda são um problema em aberto . Embora a versão que fornecemos no Cwtch Beta seja projetada para ser segura e com metadados privados, ela é bastante ineficiente e pode ser mal utilizada. Como tal, aconselhamos cautela ao usá-lo e apenas o fornecemos como um recurso opcional.

Como posso executar meu próprio servidor Cwtch? A implementação de referência para um servidor Cwtch é de código aberto . Qualquer pessoa pode executar um servidor Cwtch, e qualquer pessoa com uma cópia do pacote de chaves públicas do servidor pode hospedar grupos nesse servidor sem que o operador tenha acesso aos metadados relacionados ao grupo .

https://docs.openprivacy.ca/cwtch-security-handbook/server.html

Como posso desligar o Cwtch? O painel frontal do aplicativo possui um ícone do botão "Shutdown Cwtch" (com um 'X'). Pressionar este botão irá acionar uma caixa de diálogo e, na confirmação, o Cwtch será desligado e todos os perfis serão descarregados.

I’ve written about this before. The point of this league isn’t the meager $50 entry fee and the modest prize for winning it. It’s avoiding the downside of losing the steakhouse side bet wherein you foot the bill (one year I paid $520) for a bunch of greedy gluttonous douches who stuff their faces on your dime.*

It’s a 14-team, half-PPR auction, with IDPs instead of team defenses. Here are the results:

*It’s well known I’m the greediest most gluttonous douche when I win the bet, and that is often.

My strategy was to buy three elite receivers and skimp everywhere else. It was going well until I price-enforced on Chris Olave (who I hate at his second-round ADP) and got stuck for $31. I would much rather have gone the extra mile for a $47 Amon-Ra St. Brown or spent it instead on a running back.

I thought I’d be able to get RBs cheap late too, but that wasn’t the case. After bowing out on an $18 Rhamondre Stevenson, I found myself bidding up Brian Robinson (who I like) to $16. And I wanted to pair Jerome Ford ($11) with Nick Chubb ($14), but he too got out of reach late.

Everything else went fine. I spent $4 combined on Tua Tagovailoa and Danny Dimes who in this running-QB-friendly format has more value. I also got Rashid Shaheed late because I think he’s a better player in real life than Olave and felt like I needed the insurance after that mistake.

All things considered, the draft was fine — CeeDee Lamb and Ja’Marr Chase are two top-seven overall picks, Olave is a second rounder and Stefon Diggs goes late third-early fourth, and that’s in the NFFC’s 12-team format, though unlike this, it’s full PPR.

Most nematodes are beneficial and "graze" on black vine weevil, currant borer moth, fungus gnats, other weevils, scarabs, cutworms, webworms, billbugs, mole crickets, termites, peach tree borer and carpenter worm moths.

They also predate bacteria, recycling nutrients back into the soil and by doing so stimulates bacterial activity. They act as microbial taxis by transporting microbes to new locations of soil as they move through it while providing aeration.

タイトルは釣りです。そんなこと微塵も思っていません。 本稿はアウトボックスモデルの実装に関してうだうだ考えるコーナーです。 ダムスに関して何か言いたいわけではないので先にタイトル回収しておきます。

• NIP-65を守る気なんかさらさら無いのにNIP-65に書いてあるkind:10002のReadリレーの意味を知っていながら全然違う使い方をしているのは一部の和製クライアントの方だよね
• NIP-65を守る気が無いならkind:10002を使うべきではなく、独自仕様でリレーを保存するべきだよね
• アウトボックスモデルを採用しているクライアントからすれば仕様と異なる実装をしてしまっているクライアントが迷惑だと思われても仕方ないよね
• と考えればダムスの方が潔いよね
• とはいえkind:3のcontentは空にしろって言われてんだからやっぱダムスはゴミだわ
• やるとしたらRabbitみたいにローカルに保存するか、別デバイス間で同期したいならkind:30078を使うべきだよね

アウトボックスモデルはなぜ人気がないのか

言ってることはとてもいいと思うんですよ。 欠点があるとすれば、

• 末端のユーザーからすればreadリレーとwriteリレーと書かれると直感的にイメージされるものとかけ離れている
• 正しく設定してもらうには相当の説明が必要
• フォローTLを表示しようとすれば非常にたくさんのリレーと接続することになり現実的ではない
• なるほど完璧な作戦っスねーっ 不可能だという点に目をつぶればよぉ～

余談ですが昔irisでログインした時に localhost のリレーに繋ごうとしてiris壊れたって思ったけど今思えばアウトボックスモデルを忠実に実装してたんじゃないかな…。

現実的に実装する方法は無いのか

これでReadすべきリレーをシミュレーションできる。 https://nikolat.github.io/nostr-relay-trend/ フォローイーのWriteリレーを全部購読しようとすると100個近いリレー数になるので現実的ではありません。 しかしフォローイーのWriteリレーのうち1個だけでよい、とする条件を仮に追加すると一気にハードルが下がります。私の場合はReadリレー含めて7個のリレーに収まりました。 Nos Haikuはとりあえずこの方針でいくことにしました。

今後どうしていきたいのか

エンドユーザーとしての自分の志向としては、自分が指定したリレーだけを購読してほしい、勝手に余計なリレーを読みに行かないでほしい、という気持ちがあり、現状の和製クライアントの仕様を気に入っています。 仮にNos Haikuでアウトボックスモデルを採用しつつ自分の決めたリレーに接続するハイブリッド実装を考えるとすれば、
あなたの購読するリレーはこれですよー - Read(inbox) Relays (あなたへのメンションが届くリレー) - wss://relay1.example.com/ - wss://relay2.example.com/ - wss://relay3.example.com/ - Followee's Write Relays (フォローイーが書き込んでいるリレー) - wss://relay4.example.com/ - wss://relay5.example.com/ - wss://relay6.example.com/

って出して、チェックボックス付けてON/OFFできるようにして最終的に購読するリレーをユーザーに決めてもらう感じかな……って漠然と考えています。よほど時間を持て余したときがあればやってみるかも。

あとリレーを数は仕方ないとしてリレーごとにフォローイーの投稿だけを取得するようにした方が理にかなってるよね。全部のリレーから全部のフォローイーの投稿を取得しようとしたら(実装はシンプルで楽だけど)通信量が大変だよね。 rx-nostr の Forward Strategy ってリレーごとにREQかえて一度に購読できるっけ？

常にひとつ以下の REQ サブスクリプションを保持します。

って書いてあるから無理なのかな？ あとReadリレーは純粋に自分へのメンション(pタグ付き)イベントのみを購読するようにした方がいい気がする。スパム対策としてかなり有効だと思うので。スパムはNIP-65に準拠したりはしていないでしょうし。 まぁ、NIP-65に準拠していないクライアントからのメンションは届かなくなってしまうわけですが。

Ich liebe Pareto. Für das was es ist, viel mehr aber für das was es derzeit wird - der Marktplatz der Ideen. Er entsteht durch gemeinsames Engagement von Entwicklern, Autoren und aktiven Lesern. Es ist ein lebendiges Medium, das jeden Tag wächst, quantitativ wie qualitativ, durch offene Interaktion, was es in dieser Form einzigartig macht.\ \ Mein Text ist inspiriert durch den Artikel von Alexa Rodrian vom 22. Mai über den Auftritt von Wolf Biermann bei der Verleihung des Deutschen Filmpreises.  Alexa ist keine Publizistin, genau wie zahlreiche unserer Autoren, aber sie hat einen bemerkenswerten Beitrag verfasst. Ich habe ihn spontan geliked, kommentiert und mit einer Spende honoriert. In den vergangenen Tagen habe ich viel darüber reflektiert, und Pareto ermöglicht es mir, und jedem anderen, diese Überlegungen zur “Causa Biermann” hier darzulegen.

MSN kommentierte die anstößige Rede wie folgt: mit einem verfälschten Golda-Meir-Zitat lenkte Biermann das Thema auf das Sterben in Gaza, für das er die Palästinenser selbst verantwortlich machte. „Dass ihr unsere Söhne ermordet habt, werden wir Euch eines Tages verzeihen“, habe Meir zu den Palästinensern gesagt, „aber wir werden euch niemals verzeihen können, dass ihr unsere Söhne gezwungen habt, selber Mörder zu werden.“ Alexa Rodrian, in einer Mischung aus Enttäuschung und Empörung, eröffnete ihren Artikel wie folgt:

„Triff niemals deine Idole“ heißt ein gängiger Ratschlag. In gewendeten Zeiten stehen zu dem die Werte auf dem Kopf – und manche Künstler mit ihnen. Die Worte, die aus manch ihrer Mündern kommen, wirken, als hätte eine fremde Hand sie auf deren Zunge gelegt. Die fremde Hand ist bei Biermann eher unwahrscheinlich, denn sein Hang zu Provokationen und Verletzungen haben Tradition, man erinnere sich an den legendären Auftritt bei einer Feierstunde im Bundestag 2014 in der er die Mitglieder der Linksfraktion als “elenden Rest“ und ”Drachenbrut” bezeichnete. Oder seine Beschimpfungen der (ostdeutschen) Wähler von AfD und BSW im August 2024 in einem Zeit-Interview:  „Die, die zu feige waren in der Diktatur, rebellieren jetzt ohne Risiko gegen die Demokratie.  Den Bequemlichkeiten der Diktatur jammern sie nach, und die Mühen der Demokratie sind ihnen fremd.“

Im Februar 2025 wurde Wolf Biermann für sein Lebenswerk mit einem Musikpreis der GEMA ausgezeichnet. Was aber ist sein Lebenswerk, sein mutiges Engagement in der Opposition der DDR bis 1976 oder seine verfehlten Rüpeleien in der Gegenwart? Ein solcher Preis ist fragwürdig, denn kein Lebenswerk ist konsistent, und die Bewertung abhängig von subjektiven Maßstäben. Meist wählen wir unsere Idole nach unseren Idealen, aber die können sich verändern, ebenso wie das Idol. Beethoven widmete seine 3. Sinfonie (Eroica) Napoleon, zog die Widmung aber zurück als dieser sich 1804 zum Kaiser krönen ließ. “Ist der auch nichts anderes, wie ein gewöhnlicher Mensch?” soll er wütend ausgerufen haben. Richtig! Was hatte Beethoven erwartet, einen Gott? “Hosianna” und “kreuzigt ihn” sind Affekte die durch unsere Projektionen verursacht und den Realitäten nie gerecht werden. 

Den Preis für sein Lebenswerk kann Wolf Biermann behalten. Er hat Millionen von Menschen in der DDR Mut gemacht. Er hat zahlreiche großartige Gedichte und Lieder verfasst, das behalte ich gerne in Erinnerung. Nun hat er sich selbst vom Sockel gestürzt und durch seinen Empathiemangel das Image beschädigt. Das hätte er vermeiden können, wenn er sich an die Worte seines Lehrmeisters Brecht erinnert hätte.

...\ Dabei wissen wir doch:\ Auch der Hass gegen die Niedrigkeit\ verzerrt die Züge.\ Auch der Zorn über das Unrecht\ Macht die Stimme heiser. Ach, wir\ Die wir den Boden bereiten wollten für die Freundlichkeit\ Konnten selber nicht freundlich sein.\ ...

An die Nachgeborenen

Er hätte auch von der Medizin nehmen können, die er selbst für andere entwickelt hat \ (1966 für seinen Freund Peter Huchel).

…\ Du, laß dich nicht verhärten\ in dieser harten Zeit.\ Die allzu hart sind, brechen,\ die allzu spitz sind, stechen\ und brechen ab sogleich.\ …

Die Ermutigung

PS: Fortsetzung folgt in der Reihe \ “Was wir von großen Persönlichkeiten lernen können, wenn wir ihnen zuhören würden."

From the ages of 8-11, I spent my summers in Saltaire, Fire Island, a tiny town across the bay from Bayshore Long Island, accessible only by ferry. I vaguely recall the first summer our parents enrolled my younger brother Damon and me in day camp where they made us swim in the cold, jelly-fish-ridden bay water early in the morning. We quit the camp within the week and were largely left to our own devices after that.

The island didn’t have cars, so you got around by bike. That meant it was safe for kids, and late-70s/early-80s parents could check out entirely. By the time I was 10 or 11, I would wake up whenever it suited me, scarf down a bowl of cereal, grab my bike and return for dinner. No one knew where we were — though the baseball field was a good bet — and no one cared.

I remember one time we brought a two-man inflatable raft to the ocean on a choppy day and had the bright idea to ride the waves in it. We got so destroyed by one wave, Damon wound up face-down in the sand underneath the raft. He was crying, but no real harm done.

. . .

To this day, I often find myself projecting into the future. “In 12 hours, I’ll be back in Lisbon, in 48 hours, I’ll be done with my running for the week, in 72 hours, etc.” And when the time comes, and I’m done with whatever travel or unpleasant task, I’ll start all over again.

If you tell this to someone, they’ll often say, “You need to be in the present.” Yeah no shit. That’s like telling someone you’re an alcoholic and them saying, “You should stop drinking.” It’s a bad habit, I’m aware. But where did this habit come from, and why is it so entrenched?

. . .

My summers were a stark contrast to the school year where like everyone else I was up at 7:00 am, exhausted and forced to sit through class after class all day, the teachers droning on about something in which I had no interest. I remember watching the clock, as though trying to make the hands move faster with my mind. Only 20 minutes left, only 10 minutes, only five. Thank God it’s Friday.

. . .

I’ve never had a real job. I worked on the Truckee River one summer blowing up rafts, stacking them on trucks and putting people in the water. I cleaned houses one summer, I worked for free during law school for the NY Attorney General’s office, I ghost wrote car blurbs for Motor Trend and Car And Driver and then I worked for RotoWire (in fantasy sports) for 22 years before we sold it. The idea of grinding away at a law firm or some other joyless menial mental labor filled me with dread. Even tedious tasks like editing our annual NFL magazine, going over the copy word by word four or five times was torture. And I had a dream job and owned part of the company.

. . .

I partied a lot in my 20s and 30s, and it was not without consequence. I have a beautiful 12-YO daughter now, but we started too late to have more than one kid. Had I known then what I know now, I would have started a big family much earlier. I would have been more serious and made it a priority. But even though I wasn’t exactly an alcoholic, I had a strong urge to use the weekend as an escape. It was my time, and I wanted to use it to chase the pleasures that were denied to me during the slog of the work week.

. . .

For parents, school is kid storage, but for kids like me it was prison. My biggest takeaway was there are dreadful, pointless things society wants from you, and you should get those done with the least possible effort so you could do whatever you wanted later. That life is divided into appeasing the machine and having fun, and the problem to solve was how to get rich despite having a very low tolerance for appeasement. The point of getting rich was to do whatever you wanted whenever you wanted and to dispense with the dreadful, pointless things forever.

. . .

Now that I have no job, and the dreadful, pointless things are kept to a minimum, I mostly do whatever I want. But the younger version of me would be surprised to know that includes running at the track three times a week, doing pull-ups at the local park, writing and editing my own essays, learning and using to the extent I’m capable the challenging new freedom tech protocols (bitcoin and nostr.) I’ve largely stopped drinking, almost never smoke weed, fast once a week, am gluten-free, rarely eat junk food, don’t drive a fancy car. I save rather than spend most of my money.

There is nothing from which to escape and nowhere to go anymore. And yet my mind still projects into the future, perpetuating the dichotomy between obligations and leisure, indentured servitude and escapism. It’s as if I’m back in Saltaire, the whole day every day in front of me, but it’s only June, and I haven’t yet adjusted fully to the reality that school’s out, and it’s really, actually summer.

Just as soon as I post this essay, walk the dog, do my pull-ups at the park, I’ll start to relax and enjoy myself.

Bitcoin je peer to peer elektronski keš, novi oblik digitalnog novca koji se može prenositi između ljudi ili računara, bez potrebe za učestvovanjem pouzdanog posrednika (kao što je banka) i čije izdavanje nije pod kontrolom nijedne stranke.

Zamislite papirni dolar ili metalni novčić. Kad taj novac date drugoj osobi, ona ne mora da zna ko ste vi.

On samo treba da veruju da novac koji dobiju od vas nije falsifikat. Obično, proveravanje falsifikata „fizičkog“ novca, ljudi rade koristeći samo oči i prste ili koristeći specijalnu opremu za testiranje ukoliko se radi o značajnijoj sumi novca.

Većina plaćanja u našem digitalnom društvu vrši se putem Interneta korišćenjem neke posredničke usluge: kompanije za izdavanje kreditnih kartica poput Visa, snabdevača digitalnih plaćanja kao što je PayPal ili Apple Pay ili mrežne platforme poput WeChat u Kini.

Kretanje ka digitalnom plaćanju sa sobom donosi oslanjanje na nekog centralnog aktera koji mora odobriti i verifikovati svaku uplatu.

Priroda novca se promenila od fizičkog predmeta koji možete da nosite, prenesete i autentifikujete do digitalnih bitova koje mora da čuva i verifikuje treća strana koja kontroliše njihov prenos.

Odricanjem od gotovine u korist „udobnih“ digitalnih plaćanja, mi takođe stvaramo sistem u kome dajemo ogromna ovlašćenja onima koji bi poželeli da nas tlače.

Platforme za digitalno plaćanje postale su osnova distopijskih autoritarnih metoda kontrole, poput onih koje kineska vlada koristi za nadgledanje disidenata i sprečava građane, čije ponašanje im se ne svidja, da kupuju robu i plaćaju usluge.

Bitcoin nudi alternativu centralno kontrolisanom digitalnom novcu sa sistemom koji nam vraća prirodu korišćenja keša – čovek čoveku, ali u digitalnom obliku.

Bitcoin je digitalno sredstvo koje se izdaje i prenosi preko mreže međusobno povezanih računara, od koji svaki od njih samostalno potvrđuje da svi ostali igraju po pravilima.

Bitcoin Mreža

Odakle Potiče Bitcoin?

Bitcoin je izumela osoba ili grupa poznata pod pseudonimom Satoshi Nakamoto, oko 2008. godine.

Niko ne zna Satoshijev identitet, a koliko znamo, oni su nestali i o njima se godinama ništa nije čulo.

11.februara 2009. godine, Satoshi je pisao o ranoj verziji Bitcoin-a na mrežnom forumu za cypher­punkere, ljude koji rade na tehnologiji kriptografije i koji su zabrinuti za privatnost i slobodu pojedinca.

Iako ovo nije prvo zvanično objavljivanje Bitcoin-a, sadrži dobar rezime Satoshi-jevih motiva.

Razvio sam novi P2P sistem e-keša otvorenog koda pod nazivom Bitcoin. Potpuno je decentralizovan, bez centralnog servera ili pouzdanih stranki, jer se sve zasniva na kripto dokazima umesto na poverenju. […]

Osnovni problem konvencionalne valute je potpuno poverenje koje je potrebno za njeno funkcionisanje. Centralnoj banci se mora verovati da neće devalvirati valutu, ali istorija tradicionalnih valuta je puna primera kršenja tog poverenja. Bankama se mora verovati da drže naš novac i prenose ga elektronskim putem, ali one ga daju u talasima kreditnih balona sa delićem rezerve. Moramo im verovati sa našom privatnošću, verovati im da neće dozvoliti da kradljivci identiteta pokradu naše račune. Njihovi ogromni režijski troškovi onemogućavaju mikro plaćanja.

Generaciju ranije, višekorisnički time-sharing računarski sistemi imali su sličan problem. Pre pojave jake enkripcije, korisnici su morali da imaju pouzdanje u zaštitu lozinkom kako bi zaštitili svoje fajlove […]

Tada je jaka enkripcija postala dostupna širokim masama i više nije bilo potrebno poverenje. Podaci bi se mogli osigurati na način koji je fizički bio nemoguć za pristup drugima, bez obzira iz kog razloga, bez obzira koliko je dobar izgovor, bez obzira na sve.

Vreme je da imamo istu stvar za novac. Uz e-valutu zasnovanu na kriptografskom dokazu, bez potrebe da verujete posredniku treće strane, novac može biti siguran i transakcije mogu biti izvršene bez napora. […]

Rešenje Bitcoin-a je korišćenje peer-to-peer mreže za proveru dvostruke potrošnje. Ukratko, mreža radi poput distribuiranog servera vremenskih žigova, obeležavajući prvu transakciju koja je potrošila novčić. Potrebna je prednost prirode informacije koju je lako širiti, ali je teško ugušiti. Za detalje o tome kako to funkcioniše, pogledajte članak o dizajnu na bitcoin.org

Satoshi Nakamoto

Koje Probleme Rešava Bitcoin?

Razdvojimo neke od Satoshi-jevih postova kako bismo uvideli razloge njegove motivacije.

„Razvio sam novi P2P sistem e-keša otvorenog koda.“

P2P je skraćenica za peer to peer i ukazuje na sistem u kojem jedna osoba može da komunicira sa drugom bez ikoga u sredini, kao medjusobno jednaki.

Možete se setiti P2P tehnologija za razmenu datoteka poput Napster-a, Kazaa-e i BitTorrrent-a, koje su prve omogućile ljudima da dele muziku i filmove bez posrednika.

Satoshi je dizajnirao Bitcoin kako bi omogućio ljudima da razmenjuju e-keš, elektronski keš, bez prolaska preko posrednika na približno isti način.

Softver je otvorenog koda, što znači da svako može videti kako funkcioniše i doprineti tome.

Ne treba da verujemo ni u šta što je Satoshi napisao u svom postu o tome kako softver radi.

Možemo pogledati kod i sami proveriti kako to funkcioniše. Štaviše, možemo promeniti funkcionalnost sistema promenom koda.

„Potpuno je decentralizovan, bez centralnog servera ili pouzdanih stranki …“

Satoshi napominje da je sistem decentralizovan kako bi se razlikovao od sistema koji imaju centralnu kontrolu.

Prethodne pokušaje stvaranja digitalne gotovine poput DigiCash-a od strane Davida Chaum-a podržavao je centralni server, računar ili skup računara koji je bio odgovoran za izdavanje i verifikaciju plaćanja pod kontrolom jedne korporacije.

Takve, centralno kontrolisane privatne šeme novca, bile su osuđene na propast; ljudi se ne mogu osloniti na novac koji može nestati kada kompanija prestane sa poslovanjem, bude hakovana, pretrpi pad servera ili je zatvori vlada.

Bitcoin održava mreža pojedinaca i kompanija širom sveta.

Da bi se Bitcoin isključio, bilo bi potrebno isključiti desetine do stotine hiljada računara širom sveta u isto vreme, zauvek, od kojih su mnogi na nepoznatim lokacijama.

Bila bi to beznadežna igra, jer bi svaki napad ove prirode jednostavno podstakao stvaranje novih Bitcoin čvorova ili računara na mreži.

„… sve se zasniva na kripto dokazima umesto na poverenju“

Internet, a u stvari i većina savremenih računarskih sistema, izgrađeni su na kriptografiji, metodi prikrivanja informacija, tako da je može dekodirati samo primalac informacije.

Kako se Bitcoin oslobađa potrebe za poverenjem? Umesto da verujemo nekome ko kaže „Ja sam Alisa“ ili „Imam 10 $ na računu“, možemo koristiti kriptografsku matematiku da bismo izneli iste činjenice na način koji je vrlo lako verifikovati od strane primaoca dokaza ali ga je nemoguće falsifikovati.

Bitcoin u svom dizajnu koristi kriptografsku matematiku kako bi učesnicima omogućio da provere ponašanje svih ostalih učesnika, bez poverenja u bilo koju centralnu stranku.

„Moramo im verovati [bankama] sa našom privatnošću, verovati im da neće dozvoliti da kradljivci identiteta pokradu naše račune“

Za razliku od korišćenja vašeg bankovnog računa, sistema digitalnog plaćanja ili kreditne kartice, Bitcoin omogućava dvema stranama da obavljaju transakcije bez davanje bilo kakvih ličnih podataka.

Centralizovana skladišta potrošačkih podataka koji se čuvaju u bankama, kompanijama sa kreditnim karticama, procesorima plaćanja i vladama, predstavljaju pravu poslasticu za hakere.

Kao dokaz Satoshi-jeve poente služi primer iz 2017. godine kada je Equifax masovono kompromitovan, kada su hakeri ukrali identifikacione i finansijske podatke za više od 140 miliona ljudi.

Bitcoin odvaja finansijske transakcije od stvarnih identiteta.

Na kraju krajeva, kada nekome damo fizički novac, on nema potrebu da zna ko smo, niti treba da brinemo da će nakon naše razmene moći da iskoristi neke informacije koje smo mu dali da ukrade još našeg novca.

Zašto ne bismo očekivali isto, ili čak i bolje, od digitalnog novca?

„Centralnoj banci se mora verovati da neće devalvirati valutu, ali istorija tradicionalnih valuta je puna primera kršenja tog poverenja.“

Pojam tradicionalna valuta, odnosi se na valutu izdatu od strane vlade i centralne banke, koju vlada proglašava zakonskim sredstvom plaćanja.

Istorijski, novac je nastao od stvari koje je bilo teško proizvesti, koje su bile lake za proveravanje i transport, poput školjki, staklenih perli, srebra i zlata.

Kad god bi se nešto koristilo kao novac, postojalo je iskušenje da se stvori više toga.

Ako bi neko pronašao vrhunsku tehnologiju za brzo stvaranje velike količine nečega, ta stvar bi izgubila vrednost.

Evropski naseljenici uspeli su da liše afrički kontinent bogatstva trgujući staklenim perlicama koje su se lako proizvodile za ljudske robove.

Isto se dogodilo sa američkim indijancima, kada su kolonisti otkrili način brze proizvodnje vampum školjki, koje su starosedeoci smatrali retkim.

Vremenom, širom sveta ljudi su shvatili da je samo zlato dovoljno retko da deluje kao novac, bez straha da bi neko drugi mogao da ga stvori u velikim količinama.

Polako smo prešli sa svetske ekonomije koja je koristila zlato kao novac na onu gde su banke izdavale papirne sertifikate kao dokaz posedovanja tog zlata.

Nixon je okončao međunarodnu konvertibilnost američkog dolara u zlato 1971. godine, privremenim rešenjem, koje je ubrzo postalo trajno.

Kraj zlatnog standarda omogućio je vladama i centralnim bankama da imaju punu dozvolu da povećavaju novčanu masu po svojoj volji, razredjujući vrednost svake novčanice u opticaju, poznatije kao umanjenje vrednosti.

Iako je izdata od strane vlade, suštinska tradicionalna valuta je novac koji svi znamo i svakodnevno koristimo, ipak je relativno novo iskustvo u opsegu svetske istorije.

Moramo verovati našim vladama da ne zloupotrebljavaju njegovo štamparije, i ne treba nam puno muke da nadjemo primere kršenja tog poverenja.

U autokratskim i centralno planiranim režimima gde vlada ima prst direktno na mašini za novac, kao što je Venecuela, valuta je postala gotovo bezvredna.

Venecuelanski Bolivar prešao je sa 2 bolivara za 1 američki dolar, koliko je vredeo 2009. godine, na 250.000 bolivara za 1 američki dolar 2019. godine.

Pogledajte koliko novčanica je bilo potrebno za kupovinu piletine u Venecueli posle hiperinflacije.

Satoshi je želeo da ponudi alternativu tradicionalnoj valuti čija se ponuda uvek nepredvidivo širi.

Da bi sprečilo umanjenje vrednosti, Satoshi je dizajnirao novčani sistem gde je zaliha bila fiksna i izdavana po predvidljivoj i nepromenjivoj stopi.

Postojaće samo 21 milion Bitcoin-a.

Međutim, svaki Bitcoin se može podeliti na 100 miliona jedinica koje se sada nazivaju satoshis (sats-ovi), što će činiti ukupno 2,1 kvadriliona satoshi-a u opticaju oko 2140. godine.

Pre Bitcoin-a nije bilo moguće sprečiti beskrajnu reprodukciju digitalnih sredstava.

Kopirati digitalnu knjigu, audio datoteku ili video zapis i poslati ga prijatelju, je jeftino i lako.

Jedini izuzeci od toga su digitalna sredstva koja kontrolišu posrednici.

Na primer, kada iznajmite film sa iTunes-a, možete ga gledati na vašem uređaju samo zato što iTunes kontroliše distribuciju tog filma i može ga zaustaviti nakon perioda njegovog iznajmljivanja.

Slično tome, vaša banka kontroliše vaš digitalni novac. Zadatak banke je da vodi evidenciju koliko novca imate.

Ako ga prenesete nekom drugom, oni će odobriti ili odbiti takav prenos.

Bitcoin je prvi digitalni sistem koji sprovodi oskudicu bez posrednika i prvo je sredstvo poznato čovečanstvu čija je nepromenljiva ponuda i raspored izdavanja poznat unapred.

Ni plemeniti metali poput zlata nemaju ovo svojstvo, jer uvek možemo iskopati sve više i više zlata ukoliko je to isplativo.

Zamislite da otkrijemo asteroid koji sadrži deset puta više zlata nego što ga imamo na zemlji.

Šta bi se dogodilo sa cenom zlata uzimajući u obzir tako obilnu ponudu? Bitcoin je imun na takva otkrića i manipulisanje nabavkom.

Jednostavno je nemoguće proizvesti više od toga (21 miliona).

„Podaci bi se mogli osigurati na način koji je fizički bio nemoguć za pristup drugima, bez obzira iz kog razloga, bez obzira koliko je dobar izgovor, bez obzira na sve. […] Vreme je da imamo istu stvar za novac “

Naše trenutne metode obezbeđivanja novca, poput stavljanja u banku, oslanjaju se na poverenje nekome drugom da će obaviti taj posao.

Poverenje u takvog posrednika ne zahteva samo sigurnost da on neće učiniti nešto zlonamerno ili glupo, već i da vlada neće zapleniti ili zamrznuti vaša sredstva vršeći pritisak na ovog posrednika.

Međutim, videli smo bezbroj puta da vlade mogu, i zaista uskraćuju pristup novcu kada se osećaju ugroženo.

Nekom ko živi u Sjedinjenim Državama ili nekoj drugoj visoko regulisanoj ekonomiji možda zvuči glupo da razmišlja da se probudi sa oduzetim novcem, ali to se događa stalno.

PayPal mi je zamrzao sredstva jednostavno zato par meseci nisam koristio svoj račun.

Trebalo mi je više od nedelju dana da vratim pristup „svom“ novcu.

Srećan sam što živim u Europi, gde bih se bar mogao nadati da ću potražiti neko pravno rešenje ako mi PayPal zamrzne sredstva i gde imam osnovno poverenje da moja vlada i banka neće ukrasti moj novac.

Mnogo gore stvari su se dogodile, i trenutno se dešavaju, u zemljama sa manje slobode.

Banke su se zatvorile tokom kolapsa valuta u Grčkoj.

Banke na Kipru su koristile kaucije da konfiskuju sredstva od svojih klijenata.

Indijska vlada je proglasila određene novčanice bezvrednim.

Bivši SSSR, u kojem sam odrastao, imao je ekonomiju pod kontrolom vlade što je dovelo do ogromnih nestašica robe.

Bilo je nezakonito posedovati strane valute kao što je američki dolar.

Kada smo poželeli da odemo, mojoj porodici je bilo dozvoljeno da zameni samo ograničenu količinu novca po osobi za američke dolare po zvaničnom kursu koji je bio u velikoj meri različit od pravog kursa slobodnog tržišta.

U stvari, vlada nam je oduzela ono malo bogatstva koje smo imali koristeći gvozdeni stisak na ekonomiji i kretanju kapitala.

Autokratske zemlje imaju tendenciju da sprovode strogu ekonomsku kontrolu, sprečavajući ljude da na slobodnom tržištu povuku svoj novac iz banaka, iznesu ga iz zemlje ili da ga razmene u ne još uvek bezvredne valute poput američkog dolara.

To omogućava vladinoj slobodnoj vladavini da primeni sulude ekonomske eksperimente poput socijalističkog sistema SSSR-a.

Bitcoin se ne oslanja na poverenje u treću stranu da bi osigurao vaš novac.

Umesto toga, Bitcoin onemogućava drugima pristup vašim novčićima bez jedinstvenog ključa koji imate samo vi, bez obzira iz kog razloga, bez obzira koliko je dobar izgovor, bez obzira na sve.

Držeći Bitcoin, držite ključeve sopstvene finansijske slobode. Bitcoin razdvaja novac i državu

„Rešenje Bitcoin-a je korišćenje peer-to-peer mreže za proveru dvostruke potrošnje […] poput distribuiranog servera vremenskih žigova, obeležavajući prvu transakciju koja je potrošila novčić“

Mreža se odnosi na ideju da je gomila računara povezana i da mogu međusobno slati poruke.

Reč distribuirano znači da ne postoji centralna stranka koja kontroliše, već da svi učesnici koordiniraju medjusobno kako bi mreža bila uspešna.

U sistemu bez centralne kontrole, bitno je znati da niko ne vara. Ideja dvostruke potrošnje odnosi se na mogućnost trošenja istog novca dva puta.

Fizički novac odlazi iz vaše ruke kad ga potrošite. Međutim, digitalne transakcije se mogu kopirati baš kao muzika ili filmovi.

Kada novac šaljete preko banke, oni se pobrinu da isti novac ne možete da prebacujete dva puta.

U sistemu bez centralne kontrole potreban nam je način da sprečimo ovu vrstu dvostruke potrošnje, koja je u suštini ista kao i falsifikovanje novca.

Satoshi opisuje da učesnici u Bitcoin mreži rade zajedno kako bi vremenski označili (doveli u red) transakcije kako bismo znali šta je bilo prvo.

Zbog toga možemo odbiti sve buduće pokušaje trošenja istog novca.

Satoshi se uhvatio u koštac sa nekoliko zanimljivih tehničkih problema kako bi rešio probleme privatnosti, uništavanja vrednosti i centralne kontrole u ​​trenutnim monetarnim sistemima.

Na kraju je stvorio peer to peer mrežu kojoj se svako mogao pridružiti bez otkrivanja svog identiteta ili potrebe da veruje bilo kom drugom učesniku.

Kako se Bitcoin razvijao u poslednjoj deceniji?

Doprinosi izvornom kodu Bitcoina

Kada je Bitcoin pokrenut, samo nekolicina ljudi ga je koristila i pokrenula Bitcoin softver na svojim računarima za napajanje Bitcoin mreže.

Većina ljudi u to vreme mislila je da je to šala ili da će se otkriti ozbiljni nedostaci u dizajnu sistema koji će ga učiniti neizvodljivim.

Vremenom se mreži pridružilo sve više ljudi koji su pomoću svojih računara dodali sigurnost mreži.

Ljudi su počeli da menjaju Bitcoin-e za robu i usluge, dajući mu stvarnu vrednost. Pojavile su se menjačnice valuta koje su menjale Bitcoin-e za gotovo sve tradicionalne valute na svetu.

Deset godina nakon izuma, Bitcoin koriste milioni ljudi sa desetinama do stotinama hiljada čvorova koji pokreću besplatni Bitcoin softver, koji se razvija od strane stotina dobrovoljaca i kompanija širom sveta.

Bitcoin mreža je porasla kako bi obezbedila vrednost veću od stotine biliona dolara.

Računari koji učestvuju u zaštiti Bitcoin mreže poznati su kao rudari/majneri.

Oni rade u industrijskim operacijama širom sveta, ulažući milione dolara u specijalni rudarski hardver koji radi samo jedno: pobrinuti se da je Bitcoin najsigurnija mreža na planeti.

Rudari troše električnu energiju kako bi transakcije Bitcoin-a učinile sigurnim od modifikacija. Budući da se rudari međusobno takmiče za oskudan broj Bitcoin-a proizvedenih dnevno, oni uvek moraju da pronalaze najjeftinije izvore energije na planeti da bi ostali profitabilni.

Rudari rade na različitim mestima, od hidroelektrana u dalekim krajevima Kine do vetroparkova u Teksasu, do kanadskih naftnih polja koja proizvode gas koji bi u suprotnom bio odzračen ili spaljen u atmosferi.

Iako je Bitcoin popularna tema i o njemu se često raspravlja u medijima, procenjujemo da je samo nekoliko miliona ljudi na svetu počelo da redovno štedi Bitcoin.

Za mnoge ljude, posebno za one koji nikada nisu živeli pod represivnim režimima, ovaj izum novog oblika digitalnog novca izvan kontrole vlade može biti veoma izazovan za razumevanje i prihvatanje.

Zato sam ja ovde. Želim da vam pomognem da razumete Bitcoin i budete gospodar svoje budućnosti!

It is especially dangerous to be out late on the last night of November, for it is the closing scene of the revels—the last night when the dead have leave to dance on the hill with the fairies, and after that they must all go back to their graves and lie in the chill, cold earth, without music or wine till the next November comes round, when they all spring up again in their shrouds and rush out into the moonlight with mad laughter.

One November night, a woman of Shark Island, coming home late at the hour of the dead, grew tired and sat down to rest, when presently a young man came up and talked to her.

“Wait a bit,” he said, “and you will see the most beautiful dancing you ever looked on there by the side of the hill.”

And she looked at him steadily. He was very pale, and seemed sad.

“Why are you so sad?” she asked, “and as pale as if you were dead?”

“Look well at me,” he answered. “Do you not know me?”

“Yes, I know you now,” she said. “You are young Brien that was drowned last year when out fishing. What are you here for?”

“Look,” he said, “at the side of the hill and you will see why I am here.”

And she looked, and saw a great company dancing to sweet music; and amongst them were all the dead who had died as long as she could remember—men, women, and children, all in white, and their faces were pale as the moonlight.

“Now,” said the young man, “run for your life; for if once the fairies bring you into the dance you will never be able to leave them any more.”

But while they were talking, the fairies came up and danced round her in a circle, joining their hands. And she fell to the ground in a faint, and knew no more till she woke up in the morning in her own bed at home. And they all saw that her face was pale as the dead, and they knew that she had got the fairy-stroke. So the herb doctor was sent for, and every measure tried to save her, but without avail, for just as the moon rose that night, soft, low music was heard round the house, and when they looked at the woman she was dead.

It is a custom amongst the people, when throwing away water at night, to cry out in a loud voice, “Take care of the water;” or, literally from the Irish, “Away with yourself from the water”—for they say the spirits of the dead last buried are then wandering about, and it would be dangerous if the water fell on them.

One dark winter’s night a woman suddenly threw out a pail of boiling water without thinking of the warning words. Instantly a cry was heard as of a person in pain, but no one was seen. However, the next night a black lamb entered the house, having the back all fresh scalded, and it lay down moaning by the hearth and died. Then they all knew this was the spirit that had been scalded by the woman. And they carried the dead lamb out reverently and buried it deep in the earth. Yet every night at the same hour it walked again into the house and lay down and moaned and died. And after this had happened many times, the priest was sent for, and finally, by the strength of his exorcism, the spirit of the dead was laid to rest, and the black lamb appeared no more. Neither was the body of the dead lamb found in the grave when they searched for it, though it had been laid by their own hands deep in the earth and covered with the clay.

Before an accident happens to a boat, or a death by drowning, low music is often heard, as if under the water, along with harmonious lamentations, and then every one in the boat knows that some young man or beautiful young girl is wanted by the fairies, and is doomed to die. The best safeguard is to have music and singing in the boat, for the fairies are so enamoured of the mortal voices and music that they forget to weave the spell till the fatal moment has passed, and then all in the boat are safe from harm.

In March 2020, Lucas was afraid.

The economy was grinding to a halt. Markets were in freefall. In a sweeping response, the Federal Reserve launched an unprecedented intervention—buying everything from Treasury bonds and mortgages to corporate debt, expanding the money supply by $4 trillion. At the same time, the U.S. government issued over $800 billion in stimulus checks to households across the country.

These extraordinary measures may have averted a wave of business failures and bank runs—but they came at a cost: currency debasement and rising inflation. Alarmed by the scale of central bank intervention and its consequences for savers, Lucas decided to act.

In a state of mild panic, he withdrew $15,000 from his bank account and bought ten gold coins. Then he took another $10,000 and bought two bitcoins. If the dollar system failed, Lucas wanted something with intrinsic value he could use.

He mentioned his plan to his friend Daniel, who laughed.

“Why don’t you stock up on guns and cigarettes while you’re at it?” Daniel quipped. “The Fed is doing what it has to—stabilizing the economy in a crisis. Sure, $4 trillion is a lot of money, but it's backed by the most productive economy on Earth. Don’t panic. The world’s not ending.”

To prove his point, Daniel put $25,000 into the S&P 500—right at the pandemic bottom.

And he was right. Literally.

By Spring 2025, the stock market was near all-time highs. The world hadn’t ended. The U.S. economy kept moving, more or less as usual. Daniel’s investment had nearly tripled—his $25,000 had grown to $65,000.

But oddly enough, Lucas’ seemingly panicked reaction had been both prudent and profitable.

His gold coins had climbed from $1,500 to $3,300 apiece—a 120% gain. Bitcoin had soared from $5,000 to $90,000, making his two coins worth $180,000. Altogether, Lucas’s $25,000 allocation had grown to $213,000—a nearly 10x return. And his goal wasn’t even profit. It was safety.

With that kind of fortune, you’d expect Lucas to feel confident, even serene. He had more than enough to preserve his purchasing power, even in the face of years of inflation.

But in the spring of 2025, Lucas felt anything but calm.

He was uneasy—gripped by a sense that the 2020 crisis hadn’t been a conclusion, but a prelude.

In his mind, 2020 was just the latest chapter in a troubling sequence: the Asian financial crisis in 1998, the global financial crisis in 2008, the pandemic shock of 2020. Each crisis had been more sudden, more sweeping, and more dependent on emergency measures than the last.

And Lucas couldn’t shake the feeling that the next act—whenever it came—would be more disruptive, more severe, and far more damaging.

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":

1. ถ้า P1 และ P2 เป็นจุดเดียวกัน เส้น "ระหว่าง" P1 และ P2 ควรขยายเป็นเส้นสัมผัสกับเส้นโค้ง ณ จุด P1 นี้ เส้นสัมผัสนี้จะตัดกับเส้นโค้งที่จุดใหม่อีกหนึ่งจุดพอดี คุณสามารถใช้เทคนิคจากแคลคูลัสเพื่อหาความชันของเส้นสัมผัส เทคนิคเหล่านี้ใช้ได้อย่างน่าแปลกใจ แม้ว่าเราจะจำกัดความสนใจไว้ที่จุดบนเส้นโค้งที่มีพิกัดเป็นจำนวนเต็มเท่านั้น!
2. ในบางกรณี (เช่น ถ้า P1 และ P2 มีค่า x เดียวกันแต่ค่า y ต่างกัน) เส้นสัมผัสจะตั้งฉากพอดี ซึ่งในกรณีนี้ P3 = "จุดที่อนันต์"
3. 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 ครั้งติดต่อกัน

ในเส้นโค้งวงรี 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 เราสามารถมั่นใจได้ว่ามันเป็นกุญแจเดียวกันที่ใช้สร้างการยืนยันก่อนหน้านี้

ฟังก์ชันแฮช 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 ไบต์ที่เพิ่มเข้าไปที่ท้ายของข้อมูลที่กำลังถูกเข้ารหัส

รหัสตรวจสอบนี้ได้มาจากการแฮชข้อมูลที่ถูกเข้ารหัส และจึงสามารถใช้เพื่อตรวจจับข้อผิดพลาดจากการคัดลอกและการพิมพ์ได้ เมื่อโปรแกรมได้รับรหัส base58check ซอฟต์แวร์ถอดรหัสจะคำนวณรหัสตรวจสอบของข้อมูลและเปรียบเทียบกับรหัสตรวจสอบที่รวมอยู่ในรหัสนั้น

หากทั้งสองไม่ตรงกัน แสดงว่ามีข้อผิดพลาดเกิดขึ้น และข้อมูล base58check นั้นไม่ถูกต้อง กระบวนการนี้ช่วยป้องกันไม่ให้ address บิทคอยน์ที่พิมพ์ผิดถูกยอมรับโดยซอฟต์แวร์กระเป๋าเงินว่าเป็น address ที่ถูกต้อง ซึ่งเป็นข้อผิดพลาดที่อาจส่งผลให้สูญเสียเงินได้

การแปลงข้อมูล (ตัวเลข) เป็นรูปแบบ base58check มีขั้นตอนดังนี้:

1. เราเริ่มโดยการเพิ่ม prefix เข้าไปในข้อมูล เรียกว่า "version byte" ซึ่งช่วยให้ระบุประเภทของข้อมูลที่ถูกเข้ารหัสได้ง่าย ตัวอย่างเช่น: prefix ศูนย์ (0x00 ในระบบเลขฐานสิบหก) แสดงว่าข้อมูลควรถูกใช้เป็นการยืนยัน (hash) ในสคริปต์เอาต์พุต legacy P2PKH
2. จากนั้น เราคำนวณ "double-SHA" checksum ซึ่งหมายถึงการใช้อัลกอริทึมแฮช SHA256 สองครั้งกับผลลัพธ์ก่อนหน้า (prefix ต่อกับข้อมูล): checksum = SHA256(SHA256(prefix||data))
3. จากแฮช 32 ไบต์ที่ได้ (การแฮชซ้อนแฮช) เราเลือกเฉพาะ 4 ไบต์แรก ไบต์ทั้งสี่นี้ทำหน้าที่เป็นรหัสตรวจสอบข้อผิดพลาดหรือ checksum
4. 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 ที่แตกต่างกัน

compressed 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 ธุรกรรมก็จะถือว่าใช้ได้

address 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 ตามลำดับ

เมื่อทำการเขียนโค้ดเพื่อเข้ารหัสหรือถอดรหัส bech32m เราขอแนะนำอย่างยิ่งให้คุณใช้เวกเตอร์ทดสอบ (test vectors) ที่มีให้ใน BIP350 เราขอให้คุณตรวจสอบให้แน่ใจว่าโค้ดของคุณผ่านเวกเตอร์ทดสอบที่เกี่ยวข้องกับการจ่ายเงินให้กับเวอร์ชัน segwit ในอนาคตที่ยังไม่ได้รับการกำหนด สิ่งนี้จะช่วยให้ซอฟต์แวร์ของคุณสามารถใช้งานได้อีกหลายปีข้างหน้า แม้ว่าคุณอาจจะไม่สามารถเพิ่มการรองรับคุณสมบัติใหม่ ๆ ของบิตคอยน์ได้ทันทีที่คุณสมบัตินั้น ๆ เริ่มใช้งานได้

Private Key Formats

private key สามารถถูกแสดงได้ในหลาย ๆ รูปแบบที่ต่างกันซึ่งสามารถแปลงเป็นตัวเลขขนาด 256 bit ชุดเดียวกันได้ ดังที่เราจะแสดงให้ดูในตารางข้างล่างนี้ รูปแบบที่แตกต่างกันถูกใช้ในสถานการณ์ที่ต่างกัน รูปแบบเลขฐานสิบหก (Hexadecimal) และรูปแบบไบนารี (raw binary) ถูกใช้ภายในซอฟต์แวร์และแทบจะไม่แสดงให้ผู้ใช้เห็น WIF ถูกใช้สำหรับการนำเข้า/ส่งออกกุญแจระหว่างกระเป๋าเงินและมักใช้ในการแสดงกุญแจส่วนตัวแบบ QR code

รูปแบบของ private key ในปัจจุบัน

ซอฟต์แวร์กระเป๋าเงินบิตคอยน์ในยุคแรกได้สร้าง private key อิสระอย่างน้อยหนึ่งดอกเมื่อกระเป๋าเงินของผู้ใช้ใหม่ถูกเริ่มต้น เมื่อชุดกุญแจเริ่มต้นถูกใช้ทั้งหมดแล้ว กระเป๋าเงินอาจสร้าง private key เพิ่มเติม private key แต่ละดอกสามารถส่งออกหรือนำเข้าได้ ทุกครั้งที่มีการสร้างหรือนำเข้า private key ใหม่ จะต้องมีการสร้างการสำรองข้อมูลกระเป๋าเงินใหม่ด้วย

กระเป๋าเงินบิตคอยน์ในยุคหลังเริ่มใช้กระเป๋าเงินแบบกำหนดได้ (deterministic wallets) ซึ่ง private key ทั้งหมดถูกสร้างจาก seed เพียงค่าเดียว กระเป๋าเงินเหล่านี้จำเป็นต้องสำรองข้อมูลเพียงครั้งเดียวเท่านั้นสำหรับการใช้งานบนเชนทั่วไป แต่อย่างไรก็ตาม หากผู้ใช้ส่งออก private key เพียงดอกเดียวจากกระเป๋าเงินเหล่านี้ และผู้โจมตีได้รับกุญแจนั้นรวมถึงข้อมูลที่ไม่ใช่ข้อมูลส่วนตัวบางอย่างเกี่ยวกับกระเป๋าเงิน พวกเขาอาจสามารถสร้างกุญแจส่วนตัวใด ๆ ในกระเป๋าเงินได้—ทำให้ผู้โจมตีสามารถขโมยเงินทั้งหมดในกระเป๋าเงินได้ นอกจากนี้ ยังไม่สามารถนำเข้ากุญแจสู่กระเป๋าเงินแบบกำหนดได้ นี่หมายความว่าแทบไม่มีกระเป๋าเงินสมัยใหม่ที่รองรับความสามารถในการส่งออกหรือนำเข้ากุญแจเฉพาะดอก ข้อมูลในส่วนนี้มีความสำคัญหลัก ๆ สำหรับผู้ที่ต้องการความเข้ากันได้กับกระเป๋าเงินบิตคอยน์ในยุคแรก ๆ

รูปแบบของ private key (รูปแบบการเข้ารหัส) private key เดียวกันในแต่ละ format รูปแบบการแสดงผลทั้งหมดเหล่านี้เป็นวิธีต่างๆ ในการแสดงเลขจำนวนเดียวกัน private key เดียวกัน พวกมันดูแตกต่างกัน แต่รูปแบบใดรูปแบบหนึ่งสามารถแปลงไปเป็นรูปแบบอื่นได้อย่างง่ายดาย

Compressed Private Keys

คำว่า compressed private key ที่ใช้กันทั่วไปนั้นเป็นคำที่เรียกผิด เพราะเมื่อ private key ถูกส่งออกไปในรูปแบบ WIF-compressed มันจะมีความยาวมากกว่า private key แบบ uncompressed 1 Byte (เลข 01 ในช่อง Hex-compressed ในตารางด้านล่างนี้) ซึ่งบ่งบอกว่า private key ตัวนี้ มาจากกระเป๋าเงินรุ่นใหม่และควรใช้เพื่อสร้าง compressed public key เท่านั้น

private key เองไม่ได้ถูกบีบอัดและไม่สามารถบีบอัดได้ คำว่า compressed private key จริงๆ แล้วหมายถึง " private key ซึ่งควรใช้สร้าง compressed public key เท่านั้น" ในขณะที่ uncompressed private key จริงๆ แล้วหมายถึง “private key ซึ่งควรใช้สร้าง uncompressed public key เท่านั้น” คุณควรใช้เพื่ออ้างถึงรูปแบบการส่งออกเป็น "WIF-compressed" หรือ "WIF" เท่านั้น และไม่ควรอ้างถึง private key ว่า "บีบอัด" เพื่อหลีกเลี่ยงความสับสนต่อไป

ตารางนี้แสดงกุญแจเดียวกันที่ถูกเข้ารหัสในรูปแบบ WIF และ WIF-compressed

ตัวอย่าง: กุญแจเดียวกัน แต่รูปแบบต่างกัน

สังเกตว่ารูปแบบ Hex-compressed มีไบต์เพิ่มเติมหนึ่งไบต์ที่ท้าย (01 ในเลขฐานสิบหก) ในขณะที่คำนำหน้าเวอร์ชันการเข้ารหัสแบบ base58 เป็นค่าเดียวกัน (0x80) สำหรับทั้งรูปแบบ WIF และ WIF-compressed การเพิ่มหนึ่งไบต์ที่ท้ายของตัวเลขทำให้อักขระตัวแรกของการเข้ารหัสแบบ base58 เปลี่ยนจาก 5 เป็น K หรือ L

คุณสามารถคิดถึงสิ่งนี้เหมือนกับความแตกต่างของการเข้ารหัสเลขฐานสิบระหว่างตัวเลข 100 และตัวเลข 99 ในขณะที่ 100 มีความยาวมากกว่า 99 หนึ่งหลัก มันยังมีคำนำหน้าเป็น 1 แทนที่จะเป็นคำนำหน้า 9 เมื่อความยาวเปลี่ยนไป มันส่งผลต่อคำนำหน้า ในระบบ base58 คำนำหน้า 5 เปลี่ยนเป็น K หรือ L เมื่อความยาวของตัวเลขเพิ่มขึ้นหนึ่งไบต์

TIPจากหลาม: ผมว่าเขาเขียนย่อหน้านี้ไม่ค่อยรู้เรื่อง แต่ความหมายมันจะประมาณว่า เหมือนถ้าเราต้องการเขียนเลข 100 ในฐาน 10 เราต้องใช้สามตำแหน่ง 100 แต่ถ้าใช้ฐาน 16 เราจะใช้แค่ 2 ตำแหน่งคือ 64 ซึ่งมีค่าเท่ากัน

ถ้ากระเป๋าเงินบิตคอยน์สามารถใช้ compressed public key ได้ มันจะใช้ในทุกธุรกรรม private key ในกระเป๋าเงินจะถูกใช้เพื่อสร้างจุด public key บนเส้นโค้ง ซึ่งจะถูกบีบอัด compressed public key จะถูกใช้เพื่อสร้าง address และ address เหล่านี้จะถูกใช้ในธุรกรรม เมื่อส่งออก private key จากกระเป๋าเงินใหม่ที่ใช้ compressed public key WIF จะถูกปรับเปลี่ยน โดยเพิ่มต่อท้ายขนาด 1 ไบต์ 01 ให้กับ private key ที่ถูกเข้ารหัสแบบ base58check ที่ได้จะเรียกว่า "WIF-compressed" และจะขึ้นต้นด้วยอักษร K หรือ L แทนที่จะขึ้นต้นด้วย "5" เหมือนกับกรณีของคีย์ที่เข้ารหัสแบบ WIF (ไม่บีบอัด) จากกระเป๋าเงินรุ่นเก่า

Advanced Keys and Addresses

ในส่วนต่อไปนี้ เราจะดูรูปแบบของคีย์และ address เช่น vanity addresses และ paper wallets

vanity addresses

vanity addresses หรือ addresses แบบกำหนดเอง คือ address ที่มีข้อความที่มนุษย์อ่านได้และสามารถใช้งานได้จริง ตัวอย่างเช่น 1LoveBPzzD72PUXLzCkYAtGFYmK5vYNR33 อย่างที่เห็นว่ามันเป็น address ที่ถูกต้องซึ่งมีตัวอักษรเป็นคำว่า Love เป็นตัวอักษร base58 สี่ตัวแรก addresses แบบกำหนดเองต้องอาศัยการสร้างและทดสอบ private key หลายพันล้านตัวจนกว่าจะพบ address ที่มีรูปแบบตามที่ต้องการ แม้ว่าจะมีการปรับปรุงบางอย่างในอัลกอริทึมการสร้าง addresses แบบกำหนดเอง แต่กระบวนการนี้ต้องใช้การสุ่มเลือก private key มาสร้าง public key และนำไปสร้าง address และตรวจสอบว่าตรงกับรูปแบบที่ต้องการหรือไม่ โดยทำซ้ำหลายพันล้านครั้งจนกว่าจะพบที่ตรงกัน

เมื่อพบ address ที่ตรงกับรูปแบบที่ต้องการแล้ว private key ที่ใช้สร้าง address นั้นสามารถใช้โดยเจ้าของเพื่อใช้จ่ายบิตคอยน์ได้เหมือนกับ address อื่น ๆ ทุกประการ address ที่กำหนดเองไม่ได้มีความปลอดภัยน้อยกว่าหรือมากกว่าที่ address ๆ พวกมันขึ้นอยู่กับการเข้ารหัสเส้นโค้งรูปวงรี (ECC) และอัลกอริทึมแฮชที่ปลอดภัย (SHA) เหมือนกับ address อื่น ๆ คุณไม่สามารถค้นหา private key ของ address ที่ขึ้นต้นด้วยรูปแบบที่กำหนดเองได้ง่ายกว่า address อื่น ๆ

ตัวอย่างเช่น ยูจีเนียเป็นผู้อำนวยการการกุศลเพื่อเด็กที่ทำงานในฟิลิปปินส์ สมมติว่ายูจีเนียกำลังจัดการระดมทุนและต้องการใช้ address ที่กำหนดเองเพื่อประชาสัมพันธ์การระดมทุน ยูจีเนียจะสร้าง address ที่กำหนดเองที่ขึ้นต้นด้วย "1Kids" เพื่อส่งเสริมการระดมทุนเพื่อการกุศลสำหรับเด็ก มาดูกันว่า address ที่กำหนดเองนี้จะถูกสร้างขึ้นอย่างไรและมีความหมายอย่างไรต่อความปลอดภัยของการกุศลของยูจีเนีย

การสร้าง address ที่กำหนดเอง

ควรเข้าใจว่า address ของบิตคอยน์เป็นเพียงตัวเลขที่แสดงด้วยสัญลักษณ์ในรูปแบบตัวอักษร base58 เท่านั้น เพราะฉะนั้นแล้ว การค้นหารูปแบบเช่น "1Kids" สามารถมองได้ว่าเป็นการค้นหาที่อยู่ในช่วงตั้งแต่ 1Kids11111111111111111111111111111 ถึง 1Kidszzzzzzzzzzzzzzzzzzzzzzzzzzzzz มีประมาณ 5829 (ประมาณ 1.4 × 1051) address ในช่วงนั้น ทั้งหมดขึ้นต้นด้วย "1Kids" ตารางด้านล่างนี้แสดงช่วงของ address ที่มีคำนำหน้า 1Kids ลองดูรูปแบบ "1Kids" ในรูปของตัวเลขและดูว่าเราอาจพบรูปแบบนี้ใน bitcoin address บ่อยแค่ไหน โดยตารางข้างล่างนี้แสดงให้เห็นถีงคอมพิวเตอร์เดสก์ท็อปทั่วไปที่ไม่มีฮาร์ดแวร์พิเศษสามารถค้นหาคีย์ได้ประมาณ 100,000 คีย์ต่อวินาที

ความถี่ของ address ที่กำหนดเอง (1KidsCharity) และเวลาค้นหาเฉลี่ยบนคอมพิวเตอร์เดสก์ท็อป

ดังที่เห็นได้ ยูจีเนียคงไม่สามารถสร้าง address แบบกำหนดเอง "1KidsCharity" ได้ในเร็ว ๆ นี้ แม้ว่าเธอจะมีคอมพิวเตอร์หลายพันเครื่องก็ตาม ทุกตัวอักษรที่เพิ่มขึ้นจะเพิ่มความยากขึ้น 58 เท่า รูปแบบที่มีมากกว่า 7 ตัวอักษรมักจะถูกค้นพบโดยฮาร์ดแวร์พิเศษ เช่น คอมพิวเตอร์เดสก์ท็อปที่สร้างขึ้นเป็นพิเศษที่มีหน่วยประมวลผลกราฟิก (GPUs) หลายตัว การค้นหา address แบบกำหนดเองบนระบบ GPU เร็วกว่าบน CPU ทั่วไปหลายเท่า

อีกวิธีหนึ่งในการหา address แบบกำหนดเองคือการจ้างงานไปยังกลุ่มคนขุด vanity addresses กลุ่มคนขุดvanity addresses เป็นบริการที่ให้ผู้ที่มีฮาร์ดแวร์ที่เร็วได้รับบิตคอยน์จากการค้นหา vanity addresses ให้กับผู้อื่น ยูจีเนียสามารถจ่ายค่าธรรมเนียมเพื่อจ้างงานการค้นหา vanity addresses ที่มีรูปแบบ 7 ตัวอักษรและได้ผลลัพธ์ในเวลาเพียงไม่กี่ชั่วโมงแทนที่จะต้องใช้ CPU ค้นหาเป็นเดือน ๆ

การสร้างที่ address แบบกำหนดเองเป็นการใช้วิธีการแบบ brute-force (ลองทุกความเป็นไปได้): ลองใช้คีย์สุ่ม ตรวจสอบ address ที่ได้ว่าตรงกับรูปแบบที่ต้องการหรือไม่ และทำซ้ำจนกว่าจะสำเร็จ

ความปลอดภัยและความเป็นส่วนตัวของ address แบบกำหนดเอง

address แบบกำหนดเองเคยเป็นที่นิยมในช่วงแรก ๆ ของบิตคอยน์ แต่แทบจะหายไปจากการใช้งานทั้งหมดในปี 2023 มีสาเหตุที่น่าจะเป็นไปได้สองประการสำหรับแนวโน้มนี้: - Deterministic wallets: ดังที่เราเห็นในพาร์ทของการกู้คืน การที่จะสำรองคีย์ทุกตัวในกระเป๋าเงินสมัยใหม่ส่วนใหญ่นั้น ทำเพียงแค่จดคำหรือตัวอักษรไม่กี่ตัว ซึ่งนี่เป็นผลจากการสร้างคีย์ทุกตัวในกระเป๋าเงินจากคำหรือตัวอักษรเหล่านั้นโดยใช้อัลกอริทึมแบบกำหนดได้ จึงไม่สามารถใช้ address แบบกำหนดเองกับ Deterministic wallets ได้ เว้นแต่ผู้ใช้จะสำรองข้อมูลเพิ่มเติมสำหรับ address แบบกำหนดเองทุก address ที่พวกเขาสร้าง ในทางปฏิบัติแล้วกระเป๋าเงินส่วนใหญ่ที่ใช้การสร้างคีย์แบบกำหนดได้ โดยไม่อนุญาตให้นำเข้าคีย์ส่วนตัวหรือการปรับแต่งคีย์จากโปรแกรมสร้าง address ที่กำหนดเอง

• การหลีกเลี่ยงการใช้ address ซ้ำซ้อน: การใช้ address แบบกำหนดเองเพื่อรับการชำระเงินหลายครั้งไปยัง address เดียวกันจะสร้างความเชื่อมโยงระหว่างการชำระเงินทั้งหมดเหล่านั้น นี่อาจเป็นที่ยอมรับได้สำหรับยูจีเนียหากองค์กรไม่แสวงหาผลกำไรของเธอจำเป็นต้องรายงานรายได้และค่าใช้จ่ายต่อหน่วยงานภาษีอยู่แล้ว แต่อย่างไรก็ตาม มันยังลดความเป็นส่วนตัวของคนที่จ่ายเงินให้ยูจีเนียหรือรับเงินจากเธอด้วย ตัวอย่างเช่น อลิซอาจต้องการบริจาคโดยไม่เปิดเผยตัวตน และบ็อบอาจไม่ต้องการให้ลูกค้ารายอื่นของเขารู้ว่าเขาให้ราคาส่วนลดแก่ยูจีเนีย

เราไม่คาดว่าจะเห็น address แบบกำหนดเองมากนักในอนาคต เว้นแต่ปัญหาที่กล่าวมาก่อนหน้านี้จะได้รับการแก้ไข

Paper Wallets

paper wallet หรือก็คือ private key ที่พิมพ์ลงในกระดาษ และโดยทั่วไปแล้วมักจะมีข้อมูลของ public key หรือ address บนกระดาษนั้นด้วยแม้ว่าจริง ๆ แล้วมันจะสามารถคำนวณได้ด้วย private key ก็ตาม

คำเตือน: paper wallet เป็นเทคโนโลยีที่ล้าสมัยแล้วและอันตรายสำหรับผู้ใช้ส่วนใหญ่ เพราะเป็นเรื่องยากที่จะสร้างมันอย่างปลอดภัย โดยเฉพาะอย่างยิ่งความเป็นไปได้ที่โค้ดที่ใช้สร้างอาจถูกแทรกแซงด้วยผู้ไม่ประสงค์ดี และอาจจะทำให้ผู้ใช้โดนขโมยบิตคอยน์ทั้งหมดไปได้ paper wallet ถูกแสดงที่นี่เพื่อวัตถุประสงค์ในการให้ข้อมูลเท่านั้นและไม่ควรใช้สำหรับเก็บบิตคอยน์

paper wallet ได้ถูกออกแบบมาเพื่อเป็นของขวัญและมีธีมตามฤดูกาล เช่น คริสต์มาสและปีใหม่ ส่วนเหตุผลอื่น ๆ ถูกออกแบบเพื่อการเก็บรักษาในตู้นิรภัยของธนาคารหรือตู้เซฟโดยมี private key ถูกซ่อนไว้ในบางวิธี ไม่ว่าจะด้วยสติกเกอร์แบบขูดที่ทึบแสงหรือพับและปิดผนึกด้วยแผ่นฟอยล์กันการงัดแงะ ส่วนการออกแบบอื่น ๆ มีสำเนาเพิ่มเติมของคีย์และ address ในรูปแบบของตอนฉีกที่แยกออกได้คล้ายกับตั๋ว ช่วยให้คุณสามารถเก็บสำเนาหลายชุดเพื่อป้องกันจากไฟไหม้ น้ำท่วม หรือภัยพิบัติทางธรรมชาติอื่น ๆ

จากการออกแบบเดิมของบิตคอยน์ที่เน้น public key ไปจนถึง address และสคริปต์สมัยใหม่อย่าง bech32m และ pay to taproot—และแม้แต่การอัพเกรดบิตคอยน์ในอนาคต—คุณได้เรียนรู้วิธีที่โปรโตคอลบิตคอยน์อนุญาตให้ผู้จ่ายเงินระบุกระเป๋าเงินที่ควรได้รับการชำระเงินของพวกเขา แต่เมื่อเป็นกระเป๋าเงินของคุณเองที่รับการชำระเงิน คุณจะต้องการความมั่นใจว่าคุณจะยังคงเข้าถึงเงินนั้นได้แม้ว่าจะเกิดอะไรขึ้นกับข้อมูลกระเป๋าเงินของคุณ ในบทต่อไป เราจะดูว่ากระเป๋าเงินบิตคอยน์ถูกออกแบบอย่างไรเพื่อปกป้องเงินทุนจากภัยคุกคามหลากหลายรูปแบบ

Vi 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.

According to the ECB Executive Board member, the launch of the digital euro depends on the timing of the EU regulation.

The European Central Bank (ECB) is making progress in preparing for the digital euro. According to Piero Cipollone, ECB Executive Board member and coordinator of the project, the technical phase “is proceeding quickly and on schedule,” but moving to operational implementation still requires political approval of the regulation at the European level.

Speaking at the ‘Voices on the Future’ event organized by Ansa and Asvis, Cipollone outlined a possible timeline:

“If the regulation is approved at the start of 2026 — in the best-case scenario for the European legislative process — we could see the first transactions with the digital euro by mid-2028.”

Cipollone also highlighted Europe’s current dependence on electronic payment systems managed by non-European companies:

“Today in Europe, whenever we don’t use cash, any transaction online or at the supermarket has to go through credit cards, with their fees. The payment system relies on companies that aren’t based in Europe. You can see why it would make sense to have a system fully under our control.”

For the ECB board member, the digital euro would act as a direct alternative to cash in the digital world, working like “a banknote you can spend anywhere in Europe for any purpose.”

The digital euro project is part of the ECB’s broader strategy to strengthen the independence of Europe’s financial system. According to Cipollone and the Central Bank, Europe’s digital currency would be a key step toward greater autonomy in electronic payments, reducing reliance on infrastructure and services outside the European Union.

The post ECB: digital euro by mid-2028, says Cipollone appeared first on Atlas21.

The 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.”

Google izveštava o stalnom povećanju interesa u svetu za pitanje „Šta je novac?“ koji se postavlja iz godine u godinu, od 2004. do 2021., a sa naglim porastom nakon finansijske krize 2008. godine.

I izgleda se da niko nema dobar odgovor za to.

Godišnji proseci mesečnih interesa za pretragu. 100 predstavlja najveći interes za pretragu tokom čitavog perioda, koji se dogodio u decembru 2019. Podaci sa Google Trends-a.

Međutim, odgovaranje na ovo naizgled jednostavno pitanje pomoći će vam da razjasnite ulogu novca u vašem životu. Jednom kada shvatite kako novac funkcioniše, tačno ćete videti i zašto svet danas ludi – i šta učiniti povodom toga. Zato hajde da se udubimo u to.

Na pitanje šta je novac, većina ljudi otvori svoje novčanike i pokaže nekoliko novčanica – “evo, ovo je novac!”

Ali po čemu se ove novčanice razlikuju od stranica vaše omiljene knjige? Pa, naravno, zavod za izradu novčanica te zemlje je odštampao te novčanice iz vašeg novčanika kako bi se oduprla falsifikovanju, i svi ih koriste da bi kupili odredjene stvari.

Međutim, Nemačka Marka imala je sva ova svojstva u prošlosti – ali preduzeća danas ne prihvataju te novčanice. Zapravo, građani Nemačke su početkom dvadesetih godina prošlog veka spaljivali papirne Marke kako bi grejali svoje domove. Marka je imala veću vrednost kao papir za potpalu nego kao novac!

1923. nemačka valuta poznata kao Marka bila je jeftinija od uglja i drveta!

Pa šta to čini novac, novcem?

Ispostavilo se da ovo nije pitanje na koje je lako dati odgovor.

Definisanje novca

Novac nije fizička stvar poput novčanice dolara. Novac je društveni sistem koji koristimo da bismo olakšali trgovinu robom i uslugama. Međutim, tokom istorije fizička monetarna dobra igrala su ključnu ulogu u društvenom sistemu novca, često kao znakovi koji predstavljaju vrednost u monetarnom sistemu. Ovaj sistem ima tri funkcije: 1) Sredstvo Razmene, 2) Obračunsku Jedinicu i 3) Zalihu Vrednosti.

Odakle dolaze ove funkcije, i zašto su one vredne?

Šta je sredstvo razmene?

Sredstvo razmene je neko dobro koje se obično razmenjuje za drugo dobro. Najčešće objašnjenje za to kako su se pojavila sredstva razmene glasi otprilike ovako: Boris ima ječam i želeo bi da kupi ovcu od Marka. Marko ima ovce, ali želi samo piliće. Ana ima piliće, ali ona ne želi ječam ili ovce.

To se naziva problem sticaja potreba: dve strane moraju da žele ono što druga ima da bi mogle da trguju. Ako se želje dve osobe ne podudaraju, oni moraju da pronađu druge ljude sa kojima će trgovati dok svi ne pronađu dobro koje žele.

Ljudi koji trguju robom i uslugama moraju da imaju potrebe koje se podudaraju.

Vremenom, veoma je verovatno da će se određena vrsta robe, poput pšenice, pojaviti kao sredstvo razmene jer su je mnogi ljudi želeli. Uzimajući pšenicu kao primer: pšenica je rešila “sticaje potreba” u mnogim zanatima, jer čak i ako onaj koji prima pšenicu a nije želeo da je koristi za sebe, znao je da će je neko drugi želeti.

Ovo nazivamo prodajnost imovine.

Pšenica je dobar primer dobra za prodaju jer svi moraju da jedu, a od pšenice se pravi hleb. Pšenica ima vrednost kao sastojak hleba i kao dobro koje olakšava trgovinu rešavanjem problema „sticaja potreba“.

Razmislite o svojoj želji da dobijete više novčanica u eurima ili drugoj valuti. Ne možete da jedete novčanice da biste preživeli, a i ne bi vam bile od velike koristi ako poželite da ih koristite kao građevinski materijal za vašu kuću. Međutim, znate da sa tim novčanicama možete da kupite hranu i kuću.

Stvarne fizičke novčanice su beskorisne za vas. Novčanice su vam dragocene samo zato što će ih drugi prihvatiti za stvari koje su vama korisne.

Tokom dugog perioda istorije, novac je evoluirao do te mere da monetarno dobro može imati vrednost, a da to dobro ne služi za bilo koju drugu ‘suštinsku’ upotrebu, poput hrane ili energije. Umesto toga, njegova upotreba je zaliha vrednosti i jednostavna zamena za drugu robu u bilo kom trenutku koji poželite.

Šta jedno dobro čini poželjnijim i prodajnijim od drugog dobra?

Deljivost

Definicija: Sposobnost podele dobra na manje količine.

Loš Primer: Dijamante je teško podeliti na manje komade. Za zajednicu od hiljada ljudi koji dnevno izvrše milione transakcija, dijamanti čine loše sredstvo razmene. Previše su retki i nedeljivi da bi se koristili za mnoge transakcije.

Ujednačenost

Definicija: Sličnost pojedinačnih jedinica odredjenog dobra.

Loš Primer: Krave nisu ujednačene – neke su veće, neke manje, neke bolesne, neke zdrave. Sa druge strane, unca čistog zlata je jednolična – jedna unca je potpuno ista kao sledeća. Ovo svojstvo se takođe često naziva zamenljivost.

Prenosivost

Definicija: Lakoća transporta dobra.

Loš Primer: Krava nije baš prenosiva. Zlatnici su prilično prenosivi. Papirne novčanice su još prenošljivije. Knjiga u kojoj se jednostavno beleži vlasništvo nad tim vrednostima (poput Rai kamenog sistema ili digitalnog bankovnog računa) je neverovatno prenosiva, jer nema fizičkog dobra koje treba nositi sa sobom za kupovinu. Postoji samo sistem za evidentiranje vlasništva nad tim vrednostima u nematerijalnom obliku.

Kako dobro postaje sredstvo razmene?

Dobra postaju, i ostaju sredstva razmene zbog svoje univerzalne potražnje, takođe poznate kao njihova prodajnost, čemu pomažu svojstva koja su gore nabrojana.

Mnogo različitih dobara mogu u različitoj meri delovati kao sredstva razmene u ekonomiji. Danas, naša globalna ekonomija koristi valute koje izdaju države, zlato, pa čak i robu poput nafte kao sredstvo razmene.

---

Šta je obračunska jedinica?

Stvari se komplikuju kada u ekonomiji postoji mnogo robe koja se prodaje. Čak i sa samo 5 dobara, postoji 10 “kurseva razmene” između svake robe kojih svi u ekonomiji moraju da se sete: 1 svinja se menja za 15 pilića, 1 pile se menja za 15 litara mleka, desetak jaja se menja za 15 litara mleka, i tako dalje. Ako ekonomija ima 50 dobara, među njima postoji 1.225 “kurseva razmene”!

Sredstvo za merenje vrednosti

Zamislite obračunsku jedinicu kao sredstvo za merenje vrednosti. Umesto da se sećamo vrednosti svakog dobra u poredjenju sa drugim dobrima, mi samo treba da se setimo vrednosti svakog dobra u poredjenju sa jednim dobrom – obračunskom jedinicom.

Umesto da se setimo 1.225 kurseva razmene kada imamo 50 proizvoda na tržištu, mi treba da zapamtimo samo 50 cena.

Na primer, ne treba da se sećamo da litar mleka vredi 1/15 piletine ili desetak jaja, možemo da se samo setimo da litar mleka košta 1USD.

Poređenje dobara je lakše sa obračunskom jedinicom

Obračunska jedinica takođe olakšava upoređivanje vrednosti i donošenje odluka. Zamislite da pokušavate da kupite par Nike Air Jordan patika kada ih jedan prodavac prodaje za jedno pile, a drugi za 50 klipova kukuruza.

Šta je zaliha vrednosti?

Do sada smo gledali samo primere transakcija koje se odvijaju u određenom trenutku u vremenu.

Međutim, ljudi vrše transakcije tokom vremena – oni štede novac i troše ga kasnije. Da bi odredjeno dobro moglo da funkcioniše pravilno kao monetarno dobro, ono treba da održi vrednost tokom vremena.

Novac koji vremenom dobro drži vrednost daje njegovom imaocu više izbora kada će taj novac da potroši.

To znači da prodajnost dobra uključuje njegovu sposobnost da održi vrednost tokom vremena.

Šta jedno dobro čini boljom zalihom vrednosti od drugog dobra?

Trajnost

Definicija: Sposobnost dobra da vremenom zadrži svoj oblik.

Loš Primer: Jagode čine lošu zalihu vrednosti jer se lako oštete i brzo trunu.

Odluka je daleko lakša ako jedan prodavac naplaćuje 150 USD, a drugi 200 USD – odmah je očigledno koja je bolja ponuda jer su vrednosti izražene u istoj jedinici.

Teške za Proizvodnju

Definicija: Teškoće koje ljudi imaju u proizvodnji veće količine dobra.

Loš Primer: Papirne novčanice predstavljaju lošu zalihu vrednosti jer banke i vlade mogu jeftino da ih naprave.

Sa zlatom je suprotno – u ponudi se nalazi ograničena količina uprkos velikoj potražnji za njim, jednostavno zato što ga je vrlo teško iskopati iz zemlje. Ova ograničena ponuda osigurava da svaka jedinica zlata održi vrednost tokom vremena.

Kako dobra postaju zalihe vrednosti?

Dobro postaje zaliha vrednosti ako se vremenom pokaže trajnim i teškim za proizvodnju.

Samo će vreme pokazati da li je neko dobro zaista trajno i da li ga je teško proizvesti. Zbog toga neki oblici novca su postojali vekovima pre nego što je neko otkrio način da ih proizvede više, i na kraju se to dobro više nije koristilo kao novac.

Ovo je priča o školjkama, Rai kamenju i mnogim drugim oblicima novca tokom istorije.

Zlato je primer dobra koje je hiljadama godina služilo kao dobra zaliha vrednosti. Zlato se ne razgrađuje tokom vremena i još uvek ga je teško proizvesti. Hiljadama godina alhemičari su bezuspešno pokušavali da sintetišu zlato iz jeftinih materijala.

Čak i sa današnjim naprednim rudarskim tehnikama, svake godine svi svetski rudnici zlata zajedno mogu da proizvedu samo 2% od ukupne ponude zlata u prometu.

Teškoće u proizvodnji zlata daju izuzetno visok odnos “zaliha i protoka”: zaliha je broj postojećih jedinica, a protok su nove jedinice stvorene tokom određenog vremenskog perioda. Svake godine se stvori vrlo malo novih jedinica zlata, iako je potražnja za zlatom obično vrlo velika.

Kombinujući ovo sa deljivošću, ujednačenošću i prenosivošću zlata, nije ni čudo što je zlato čovečanstvu služilo kao monetarno dobro tokom poslednjih 5.000 godina. Pošto je zlato teško proizvesti, možemo ga nazvati teškim novcem (hard money).

Kao rezultat toga, svoju vrednost je u velikoj meri zadržao kroz milenijume. Cena većine dobara i usluga u pogledu zlata zapravo se vremenom smanjivala kao rezultat tehnoloških inovacija, koje sve proizvode čine jeftinijim.

Uzmimo na primer cene hrane prema praćenju Kancelarije za hranu i poljoprivredu UN-a: sa obzirom na skokove u poljoprivrednoj tehnologiji tokom poslednjih 60 godina, cene hrane drastično su pale kada se procenjuju u zlatu. To čak i važi uprkos činjenici da obični ljudi retko koriste zlato za kupovinu stvari.

Cene hrane su padale u pogledu zlata tokom proteklih 60 godina, i mnogo pre toga (FAO Indeks Cena Hrane u Zlatu)

Zaliha vrednosti omogućava ljudima da uštede novac kako bi mogli da ga ulažu u pokretanje preduzeća i obrazovanje, povećavajući produktivnost društva.

Monetarna dobra koja dobro čuvaju vrednost takođe podstiču dugoročniji pogled na život, ili kratke vremenske preference. Pojedinac može da radi 10 godina, uštedi odredjeno monetarno dobro koje je dobra zaliha vrednosti, i nema potrebe da se plaši da će njegova ušteđevina biti izbrisana krahom tržišta ili povećanjem ponude tog dobra.

Zašto su važne funkcije novca?

Kada neki oblik novca izgubi bilo koju od svojih važnih funkcija kao što su sredstvo razmene, obračunska jedinica i zaliha vrednosti, celokupna ekonomija i društvo mogu da se rastrgnu.

Tokom istorije često vidimo grupe ljudi koje eksploatišu druge iskorišćavajući nesporazume o novcu i važnosti njegovih funkcija.

Sledeće, proći ću kroz istoriju novca, prvo hipotetički da bih ilustrovao poentu, a zatim ću preći na stvarne istorijske primere. Kroz ove primere videćemo štetne efekte na društva u slučajevima kada se izgubi samo jedna od tih ključnih funkcija novca.

Novac Gubi Funkciju: Alhemičar iz Njutonije

Kroz istoriju, mnoga dobra su dolazila i odlazila kao oblici novca. Na žalost, kada se neki oblik novca ukine, ponekad postoji grupa ljudi koja eksploatiše drugi oblik manipulišući tim novcem.

Hajde da pogledamo hipotetičko selo zvano Njutonija da bismo razumeli kako dolazi do ove eksploatacije.

Zelene perle postaju Novac

Tokom stotina godina ribolova u obližnjoj reci, stanovnici Njutonije sakupljali su zelene perle iz vode. Zrnca su mala, lagana, izdržljiva, jednolična i retko se pojavljuju u reci. Ljudi prvo priželjkuju perle zbog svoje lepote. Na kraju, seljani shvataju da svi drugi žele perle – one se vrlo lako mogu prodati. Zrnca uskoro postaju sredstvo razmene i obračunska jedinica u selu: pile je 5 zrna, vreća jabuka 2 zrna, krava 80 zrna.

Ukupna ponuda perli je prilično konstantna i cene se vremenom ne menjaju mnogo. Seoski starešina je uveren da može da se opustiti u poslednjim danima živeći od svoje velike zalihe perli.

Alhemičar stvara više perli

Seoski alhemičar je poželeo da bude bogat čovek, ali nije voleo da vredno radi na tome. Umesto da traži perle u reci ili da prodaje vrednu robu drugim seljanima, on sedeo je u svojoj laboratoriji. Na kraju je otkrio kako da lako stvori stotine perli sa malo peska i vatre.

Seljani koji su tragali za perlama u reci bili su srećni ako bi svaki dan pronašli po 1 zrno. Alhemičar je mogao da proizvede stotine uz malo napora.

Alhemičar troši svoje perle

Budući da je bio prilično zao, alhemičar nije svoj metod pravljenja zrna delio ni sa kim drugim. Stvorio je sebi još više perli i počeo da ih troši za dobra na tržištu u Njutoniji. Tokom sledećih meseci, alhemičar je kupio farmu pilića, nekoliko krava, finu svilu, posteljine i ogromno imanje. On je imao priliku da kupi ova dobra po normalnim cenama na tržištu.

Alhemičarevo trošenje ostavljalo je seljanima mnogo perli, ali malo njihove vredne robe.

Svi seljani su se osećali bogatima – imali su tone perli! Međutim, polako su primetili da i svi ostali takodje imaju tone.

Cene počinju da rastu

Uzgajivač pilića primetio je da sva roba koju je trebalo da kupi na pijaci poskupela. Džak jabuka sada se prodaje za 100 perli – 50 puta više od njihove cene pre nekoliko meseci!

Iako je sada imao hiljade perli, uskoro bi mogao da ostane bez njih zbog ovih cena. Pitao se – da li zaista može sebi da priušti da prodaje svoje piliće za samo 5 perli po komadu? Morao je i on da podigne svoje cene.

Jednostavno rečeno, kao rezultat alhemičarevog trošenja njegovih novostvorenih perli, bilo je previše perli koje su jurile premalo dobara – pa su cene porasle.

Kupci robe bili su spremni da potroše više perli da bi kupili potrebna dobra. Prodavci robe su trebali da naplate više da bi bili sigurni da su zaradili dovoljno da kupe potrebna dobra za sebe.

Budući da su cene svih dobara porasle, možemo reći da se vrednost svake perle smanjila.

Nejednakost bogatstva raste

Seoski starešina, koji je vredno radio da sačuva hiljade perli, sada se našao osiromašenim i gladnim. U međuvremenu, alhemičar je udobno sedeo na svom velikom imanju sa kravama, pilićima i slugama koji su se brinuli za svaki njegov hir.

Alhemičar je efikasno ukrao bogatstvo celog sela, tako što je jeftino proizvodio perle i koristio ih za kupovinu vredne robe.

Ono što je najvažnije, kupio je robu pre nego što je tržište shvatilo da je više perli u opticaju i da ima manje robe, što je dovelo do rasta cena. Ova dodatna proizvodnja perli nije dodala korisnu robu ili usluge selu.

Eksploatacija pomoću Novca: Agri Perle

Nažalost, priča o alhemičaru iz Njutonije nije u potpunosti hipotetička. Ovaj prenos bogatstva kroz stvaranje novca ima istorijske i moderne presedane.

Na primer, afrička plemena su nekada koristila staklene perle, poznate kao “agri perle”, kao sredstvo razmene. U to vreme plemenskim ljudima je bilo veoma teško da prave staklene perle, i one su predstavljale težak novac unutar njihovog plemenskog društva.

Niko nije mogao jeftino da proizvede perle i koristiti ih za kupovinu skupe, vredne robe poput kuća, hrane i odeće.

Sve se promenilo kada su stigli Evropljani, i primetili upotrebu staklenih perli kao novca.

U to vreme, Evropljani su mogli jeftino da stvaraju staklo u velikim količinama. Kao rezultat toga, Evropljani su počeli tajno da uvoze perle i koriste ih za kupovinu dobara, usluga i robova od Afrikanaca.

Vremenom se iz Afrike izvlačila vredna roba i ljudi, dok je plemenima ostajalo mnogo perli i malo robe.

Perle su izgubile veći deo vrednosti zbog inflacije uzrokovane snabdevanjem od strane Evropljana.

Rezultat je bio osiromašenje afričkih plemena i bogaćenje Evropljana, kako to ovde objašnjava monetarni istoričar Bezant Denier.

Dragocena roba je kupljena jeftino proizvedenim monetarnim dobrom.

Profitiranje na proizvodnji novca: Emisiona dobit

Ova priča ilustruje kako se bogatstvo prenosi kada jedna grupa može jeftino da proizvodi monetarno dobro.

Razlika između troškova proizvodnje monetarnog dobra i vrednosti tog monetarnog dobra poznata je kao emisiona dobit, eng. seignorage.

Kada je monetarno dobro mnogo vrednije od troškova proizvodnje, ljudi će proizvesti više od monetarnog dobra da bi uhvatili profit od emisione dobiti.

Na kraju će ova povećana ponuda dovesti do pada vrednosti monetarnog dobra. To je zbog zakona ponude i potražnje: kada se ponuda povećava, cena (poznata i kao vrednost) dobra opada.

Novac Gubi Funkciju 2. Deo: Kejnslandski Bankar

U priči o Njutoniji, alhemičar je otkrio način da se od malo peska jeftino stvori više zelenih perli. To se u stvarnosti odigralo kroz trgovinu između Evropljana i Afrikanaca, pričom o agri perlama. Međutim, ove priče su pomalo zastarele – mi više ne trgujemo robom za perle.

Da bismo nas doveli do modernog doba, hajde da promenimo neka imena u našoj priči:

1. Selo Njutonija postaje država koja se zove Kejnsland
2. Alhemičar postaje bankar
3. Seoski starešina postaje penzioner
4. Zelene perle postaju zlato, koje niko ne može jeftinije da stvori – čak ni bankar.

Bankar Menja Papirne Novčanice za Zlato

Kao i u stvarnosti, bankar u ovoj priči nema formulu ili trik da stvori više zlata. Međutim, bankar bezbedno čuva zlato u vlasništvu svakog građanina Kejnslanda. Bankar daje svakom građaninu po jednu potvrdu za svaku uncu zlata koje ima u svom trezoru.

Te potvrde se mogu iskoristiti u bilo koje vreme za stvarno zlato. Papirne potvrde ili novčanice su mnogo pogodnije za plaćanje nego nošenje zlata kroz supermarket.

Građani su srećni – oni imaju prikladno sredstvo plaćanja u vidu bankarevih novčanica, i znaju da niko ne može da ukrade njihovo bogatstvo falsifikujući više zlata.

Građani na kraju počinju da plaćaju u potpunosti papirnim novčanicama, ne trudeći se nikad da zamene svoje novčanice za zlato. Na kraju, novčanice postaju “dobre kao i zlato” – svaka predstavlja fiksnu količinu zlata u bankarevom trezoru.

Ukupno kruži 1.000.000 novčanica, od kojih je svaka otkupljiva za jednu uncu zlata. 1.000.000 unci zlata sedi u bankarevom trezoru. Svaka novčanica je u potpunosti podržana u zlatu.

Starešina koji je sačuvao sve svoje perle u priči o Njutoniji sada je penzioner u Kejnslandu, koji svoje zlato drži u banci i planira da ugodno živi od novčanica koje je dobio zauzvrat.

Hajde da u ovu priču dodamo i novi lik: premijera Kejnslanda. Premijer naplaćuje porez od građana i koristi ga za plaćanje javnih usluga poput policije i vojske. Premijer takođe drži vladino zlato kod bankara.

Bankar Menja Papirne Novčanice za Dug

Premijer želi da osigura da nacionalno zlato ostane na sigurnom, pa banku štiti policijom. Bankar i premijer se zbog toga zbližavaju, pa premijer traži uslugu. Traži od bankara da kreira 200.000 novčanica za premijera, uz obećanje da će mu premijer vratiti za pet godina. Premijeru su novčanice potrebne za finansiranje rata. Građani Kejnslanda borili su se protiv većih poreza zbog finansiranja rata, pa je morao da se obrati bankaru.

Bankar se slaže da izradi novčanice, ali pod jednim uslovom: bankar uzima deo od 10.000 novčanica za sebe. Premijer prihvata posao kojim bankar ’kupuje državni dug’. Sada je u opticaju 1.200.000 novčanica, potpomognutih kombinacijom 1.000.000 unci zlata i ugovorom o dugu sa vladom za 200.000 novčanica.

Premijer troši svoje nove novčanice na bombe kupujući ih od dobavljača iz domaće vojne industrije, a bankar sebi kupuje veliki luksuzni stan.

Dobavljač iz vojne industrije koristi sve nove novčanice koje je dobio od premijera da kupi amonijum nitrat (đubrivo koje se koristi u bombama) za proizvodnju bombi. Sve njegove kupovine povećavaju cenu đubriva za uzgajivače pšenice u Kejnslandu, pa oni podižu cenu pšenice.

Kao uzrok toga, pekar koji kupuje pšenicu treba da podigne cenu svog hleba da bi ostao u poslu. Na taj način cene u Kejnslandu počinju da rastu, baš kao što su to činile u Njutoniji kada su nove perle ušle u opticaj.

Papirne Novčanice Više Ne Predstavljaju Zlato

Penzioner nailazi na finansijski časopis u kojem se pominje premijerov dogovor da se zaduži za finansiranje rata. Obzirom da je mudar, on zna da bombe loše vraćaju ulaganje i sumnja da će premijer ikada da vrati svoj dug.

Ako on ‘podmiri’ svoj dug, to bi ostavilo 1.200.000 novčanica u opticaju sa samo 1.000.000 unci zlata da bi ih podržalo, obezvređujući njegovu ušteđevinu. Već oseća stisak u džepu zbog porasta cena, i on odlučuje da se uputi u lokalnu banku i preda svoje novčanice i zameni ih za zlato, koje niko ne može da napravi u većoj količini.

Kada penzioner stigne u banku, on zatiče i mnoge druge okupljene oko banke. Svi oni se nadaju da će uzeti zlato koje predstavljaju njihove novčanice. Građani Kejnslanda sa pravom se plaše da njihove novčanice gube na vrednosti – oni to već osećaju zbog porasta cena.

Vrata su zaključana, sa obaveštenjem bankara na njima:

Po nalogu premijera, onom koji se plaši za stabilnost ove bankarske institucije, ova banka više neće podržavati konvertibilnost papirnih novčanica u zlato. Hvala vam!

Gomila se razilazi, ostavljena sa jednim izborom: da zadrže svoje novčanice, koje sada vrede manje od 1 unce zlata. Građani sa dovoljno finansijske stabilnosti odlučuju da ulože svoje novčanice u kupovinu akcija banke i kompanija vojne industrije, koje dobro posluju jer mogu da kupuju stvari pre nego što se povećaju tržišne cene.

Mnogi ljudi nisu u mogućnosti da investiraju – oni moraju da gledaju kako njihove zarade stagniraju i kako njihova ušteđevina polako ali sigurno gubi vrednost.

Penzioner, koji se nadao da će živeti od novčanica koje je zaradio tokom svojih 40 radnih godina, sada 40 sati nedeljno provodi iza kase u lokalnoj prodavnici, pitajući se gde je sve pošlo po zlu.

Dug Nikada Nije Otplaćen

Prošlo je nekoliko godina, a premijerov dug prema banci dolazi na naplatu. Budući da je potrošio svih 200.000 novčanica na bombe, koje nemaju baš dobar povraćaj ulaganja, on nema novčanice koje može da vrati banci. Plus, premijer želi da kupi još bombi za svoj rat.

Bankar uverava premijera da je sve u redu. Bankar će napraviti novi ugovor o dugu za 600.000 novčanica, koji bi trebao da stigne na naplatu u narednih 5 godina. Premijer može da iskoristi 200.000 od tih novih 600.000 novčanica da vrati svoj prvobitni dug prema banci, zadrži još 300.000 da kupi još bombi i da 100.000 bankaru da bi mu platio njegove usluge.

To nastavlja da se dešava – svaki put kada dug dospeva na naplatu, bankar stvara više novčanica za vraćanje starijih dugova i daje premijeru još više novca za trošenje. Ovaj ciklus se nastavlja.

Šta se dešava u Kejnslandu?

• Oni koji prvi dobiju nove novčanice, gledaju kako se njihovo bogatstvo povećava
• To uključuje bankara, premijera, vladu i sve one koji mogu da pristupe mogućnostima za investiranje u preduzeća koja prva dobiju nove novčanice (finansijske, vojne itd.).
• Cene roba rastu
• Cene se ne povećavaju ravnomerno – one se povećavaju gde god nove novčanice prvo uđu u ekonomiju i od tog trenutka imaju efekat talasa na tržišta. U našem primeru prvo raste cena amonijum nitrata, zatim cena pšenice, pa cena hleba. A tek na kraju zarade običnih ljudi.
• Štednja i životni standard opšte populacije se smanjuju
• Najviše pate oni koji žive od plate do plate i ne mogu da ulažu. Čak i oni koji su u mogućnosti da investiraju podložni su hirovima tržišta. Mnogi su prisiljeni da prodaju svoje investicije po niskim cenama tokom pada tržišta samo da bi platili svoje dnevne potrebe.
• Razlika u prihodima i bogatstvu između bogatih i siromašnih se povećava
• Bogatstvo opšte populacije se smanjuje, dok se bogatstvo onih koji su blizu mesta gde se troše nove novčanice povećava. Rezultat je disparitet koji se vremenom samo proširuje.

Da li nas novac danas eksploatiše?

Priča o Njutoniji i stvarna priča o agri perlama u Africi deluju pomalo zastarelo. Priča o Kejnslandu, međutim, deluje neobično poznato. U našem svetu cene robe uvek rastu, i vidimo rekordne nivoe nejednakosti u bogatstvu.

U poslednjem odeljku ovog našeg članka Šta je novac, proći ću kroz nastanak bankarstva i korake koji su bili potrebni da se dođe do današnjeg sistema, gde banke i vlade sarađuju u kontroli ekonomije i samog novca.

Šta su banke, i odakle su one došle?

Pojava bankarstva verovatno se dogodila da bi olakšala poljoprivrednu trgovinu i da bi povećala pogodnosti. Iako su se mnoga društva na kraju konvergirala ka upotrebi zlata i srebra kao novca, ovi metali su bili teški i opasni za nošenje kao tovar. Međutim, u mnogim slučajevima ih nije ni trebalo prevoziti. Uzmite ovaj primer:

Grad treba da plati poljoprivrednicima na selu za žito, a poljoprivrednici gradskoj vojsci za zaštitu od varvara. U ovom dogovoru zlato se kreće u oba smera: prema poljoprivrednicima u selu kako bi im se platilo žito, i nazad u grad da bi se platila vojska. Da bi olakšali ove transakcije, preduzetnici su stvorili koncept banke. Banka je zlato čuvala u sigurnom trezoru i izdavala novčanice od papira. Svaka priznanica je predstavljala potvrdu da njen imaoc poseduje određenu količinu zlata u banci. Imaoc novčanice je u svako doba mogao da uzme svoje zlato nazad vraćanjem te novčanice banci.

Korisnici banke mogli su lakše da trguju sa novčanicama od papira, i onaj koji poseduje novčanice mogao je da preuzme njihovo fizičko zlato u bilo kom trenutku. To je te novčanice učinilo “dobrim kao i zlato”.

Banke su izdržavale svoje poslovanje naplaćujući od kupaca naknadu za skladištenje zlata ili pozajmljivanjem dela zlata i zaračunavanjem kamata na njega. Trgovina na ovaj način je mogla da se odvija sa laganim novčanicama od papira umesto sa teškim vrećama zlatnika.

Ovakva praksa sa transakcijama, korišćenjem papirne valute potpomognute monetarnim dobrima, verovatno je započela u Kini u 7. veku.

Na kraju se proširila Evropom 1600-ih, a svoj zalet dobila je u Holandiji sa bankama poput Amsterdamske Wisselbanke. Novčanice Wisselbank-e često su vredele više od zlata koje ih je podržavalo, zbog dodane vrednosti njihovih pogodnosti.

Uspon nacionalnih ‘centralnih banaka’

Tokom vekova, zlato je počelo da se sakuplja u trezorima banaka, jer su ljudi više voleli pogodnosti transakcija sa novčanicama.

Na kraju, nacionalne banke u vlasništvu vlada preuzele su ulogu čuvanja zlata od privatnih banaka koje su započeli preduzetnici.

Nacionalne papirne valute potpomognute zlatnim rezervama u nacionalnim bankama zamenile su novčanice iz privatnih banaka. Sve nacionalne valute bile su jednostavno potvrde za zlato koje se nalazilo u trezoru nacionalne banke.

Ovaj sistem je poznat kao zlatni standard – sve valute su jednostavno predstavljale različite težine zlata.

U gornjem levom uglu novčanice možete videti da piše da je novčanica “zamenljiva za zlato”. Savremeni dolari nemaju ovaj natpis, ali inače izgledaju vrlo slično. Izvor

Zlatni sistem je postojao veći deo vremena, sve do Prvog svetskog rata. Vladama je bilo teško da prikupe novac za ovaj rat putem poreza, pa su morale da budu kreativne.

Kada vlade troše više nego što zarađuju na porezima, to se naziva deficitna potrošnja.

Kako vlade mogu ovo da urade? Vlade to rade tako što pozajmljuju novac prodavajući svoj dug.

Tokom Prvog svetskog rata, vlade su građanima i preduzećima prodavale vrstu duga koja se naziva ratna obveznica. Kada građanin kupi ratnu obveznicu, on preda svoj novac vladi i dobije papir u kojem je stajalo vladino obećanje da će vlasniku obveznice vratiti novac, plus kamate, za nekoliko godina.

Plakat koji obaveštava građane, tražeći od njih da kupe ratne obveznice – što predstavlja zajam vladi. Izvor

Centralne banke ‘monetizuju’ državni dug

Međutim, građani i preduzeća nisu bili voljni da kupe dovoljno ratnih obveznica za finansiranje Prvog svetskog rata.

Vlade se nisu predale – pa su zatražile od svojih nacionalnih ‘centralnih banaka’ da one kupe ove obveznice. Centralne banke su otkupile obveznice, ali ih nisu platile valutom potpomognutom postojećim zlatnim rezervama, kao što su to činili građani i banke prilikom kupovine obveznica.

Centralne banke su umesto toga davale vladi novu, sveže štampanu papirnu valutu potpomognutu samo obveznicom. Ovu valutu podržalo je samo obećanje da će im vlada vratiti dugove. Ovo je poznato kao monetizacija duga.

Budući da su ratne obveznice i valuta samo komadi papira, one su lake i jeftine za proizvodnju i mogu se napraviti u ogromnim količinama. Ono što ograničava proizvodnju i jednog i drugog je poverenje.

Ima smisla da se neko rastane od svog teško stečenog novca da kupi državnu obveznicu, samo ako veruje da će vlada da vrati svoj dug, plus kamate. Centralna banka je “krajnji kupac”, što znači da će ona da kupi državne obveznice kada to niko drugi neće da uradi.

Zapamtite, centralnu banku gotovo da ništa ne košta da kupi državne obveznice, jer oni sami štampaju valutu da bi ih kupili.

Zamislite da pridjete najskupljem automobilu u autosalonu – koji košta 100.000 USD. Mislite da je automobil lep, ali taj novac biste radije potrošili na lepši stan – tako da ste spremni da platite samo 40.000 USD za taj auto.

Sada, hajde da zamislimo da imate štampač za novac i da vas košta samo 50 USD za mastilo i papir da bi ištampali 1.000.000 USD. Vi biste odmah kupili auto, čak i ako biste morali da se cenkate sa drugim čovekom, i da ga na kraju platite 150.000 USD!

Ista stvar se dešava kada centralna banka kupuje obveznice (dugove) od vlade. Centralna banka može da stvori valutu toliko jeftino, da su spremni da plate i više nego što bi drugi platili ove obveznice i nastaviće da ih kupuju čak i kada niko drugi ne bude želeo.

Monetizacija duga uzrokuje inflaciju

Kada centralne banke monetizuju državni dug, funkcija novca kao zalihe vrednosti počinje da se nagriza. Vlada troši novi novac koji je dobila od svoje centralne banke na ratnu robu, obroke i još mnogo toga.

Cene roba rastu od ove novoštampane valute koja kruži kroz ekonomiju. Kada se cene povećavaju, to znači da se vrednost svake jedinice valute smanjuje. Svi koji drže valutu sada imaju manje vrednosti. Danas to nazivamo sporim gubitkom funkcije zalihe vrednosti u novčanoj inflaciji.

Za Nemačku nakon Prvog svetskog rata monetizacija duga izazvala je totalni slom Nemačke ekonomije i stvorila uslove za rast fašizma.

Kao deo sporazuma o prekidu vatre koji je okončao Prvi svetski rat, Nemačka je pobednicima morala da plati ogroman novac. Nemačkoj vladi je bio preko potreban novac, pa su prodale obveznice (dug) Rajhsbanci, nemačkoj centralnoj banci.

Ovaj postupak doveo je do toga da je vlada štampala toliko maraka (tadašnja nemačka valuta) da je tempo inflacije u Nemačkoj ubrzan u hiperinflaciju početkom 1920-ih. Cena vekne hleba za samo 4 godine popela se sa 1,2 marke na 428 biliona maraka.

Tokom i posle Prvog svetskog rata, SAD, Britanija, Francuska i mnoge druge vlade pratile su Nemačku u štampanju valute potpomognute državnim dugom.

To je dovelo do toga da su građani želeli da svoju papirnu valutu zamene za zlato, baš kao i penzioner iz priče o Kejnslandu.

Međutim, mnoge vlade su suspendovale konvertibilnost svojih valuta u zlato. Ovim potezom vlade su primorale svoje građane da drže nacionalnu papirnu valutu i gledaju kako se njihova ušteda smanjuje u vrednosti.

Da bi mogle da nastave da štampaju novac i da bi ga trošile na nepopularne programe za koje nisu mogle da skupljaju poreze za finansiranje – poput ratova.

Bretton Woods: Novi monetarni sistem

Nakon razaranja koja su donela dva svetska rata, vlade su uspostavile novi globalni monetarni sistem prema Bretton Woods-ovom sporazumu iz 1944. godine.

Prema ovom sporazumu, valuta svake države konvertovala se po fiksnom kursu sa američkim dolarom. Američki dolar je zauzvrat predstavljao zlato po stopi od 35 USD za jednu trojsku uncu zlata*.

Sve globalne valute su stoga još uvek bile jednostavna reprezentacija zlata, putem američkih dolara kao posrednika. Redovni građani više nisu mogli da otkupljuju svoje valute za zlato iz Sjedinjenih Država. Međutim, strane centralne banke mogle bi da dođu u Sjedinjene Države da bi zamenile dolare za zlato po stopi od 35 USD za jednu uncu zlata.

Međutim, vlada Sjedinjenih Država nije uvek držala dovoljno zlata da podrži sve dolare u opticaju. Američka vlada nastavila je da finansira proširene socijalne i vojne programe prodajom državnog duga svojoj centralnoj banci, Federalnim rezervama, koja je povećala ponudu dolara bez povećanja ponude zlata koja podupire te dolare.

*Trojna unca je standardna mera čistog zlata i ima malo veću težinu od normalne unce.

Propast Bretton Woods-a

Tokom 1970-ih, sve veći troškovi rata u Vijetnamu i stranih vlada koje su otkupljivale svoje dolare za zlato, stvorili su pritisak na Trezor Sjedinjenih Država.

Ponuda dolara je porasla, dok je zlato u posedu Sjedinjenih Država opalo. Od 1950. pa do početka 1970-ih, rezerve zlata koje je držala vlada Sjedinjenih Država smanjile su se za više od 50%, sa 20 metričkih tona na samo 8 metričkih tona.

Godine 1970. država je imala zlata u vrednosti od samo 12 biliona dolara po zvaničnom kursu od 35 dolara za trojsku uncu zlata. Tokom ovog istog vremenskog perioda, ukupna ponuda američkih dolara otišla je sa oko 32 biliona USD na skoro 70 biliona USD.

Zvanične rezerve zlata u SAD-u su naglo padale od 1950. do 1970. godine, dok su se dolari u opticaju povećavali. Izvor: Wikipedia, DollarDaze.org

Američka vlada nije bila u stanju da potkrepi dolare zlatom od 35 dolara po trojnoj unci, što dovelo do rizika za čitav globalni monetarni sistem.

Početkom sedamdesetih godina, trojna unca zlata trebala je da vredi 200 USD da bi u potpunosti podržala sve američke dolare u opticaju. Rečeno na drugi način, Sjedinjene Države su pokušavale da kažu svetu da jedan dolar vredi 1/35 trojne unce zlata, ali u stvarnosti dolar je vredeo samo 1/200 trojne unce.

Kad su strane vlade trebale da pribave dolare za međunarodnu trgovinu i rezerve, bile su opelješene. Francuska vlada je to shvatila šezdesetih godina prošlog veka i počela je da prodaje svoje američke dolare za zlato po zvaničnom kursu od 35 dolara za trojsku uncu zlata.

Zemlje su počinjale da se bude iz šeme američke vlade. SAD su krale bogatstvo putem emisione dobiti, prodajući dolare za 1/35 trojne unce zlata, kada su vredeli samo 1/200 trojske unce.

Nixonov Šok ulazi u ’tradicionalni’ novac

Da bi kuća od karata mogla da ostane na mestu, predsednik Nixon je 1971. najavio da će američka vlada privremeno da obustavi konvertibilnost dolara u zlato.

Strane vlade više nisu mogle da polažu pravo na zlato svojim papirnim dolarima, a dolar više nije bio “poduprt” zlatom. Nixon je tvrdio da će ovo stabilizovati dolar.

50 godina kasnije, kristalno je jasno da je ovo samo pomoglo dolaru da izgubi vrednost i da ovaj “privremeni” program još uvek traje.

Pre 1971. godine, sve globalne valute bile su vezane za američki dolar putem Bretton Woods-ovog sporazuma. Kada je Nixon promenio američki dolar iz dolara podržanog u zlatu u dolar podržan dugom, ovim je promenio i svaku drugu valutu na Zemlji.

Sam je učinio da se celokupna svetska ekonomija zasniva na dugovima. Valute više nisu predstavljale zlato, već su predstavljale vrednost državnog duga.

Zlatni Standard se nikada nije vratio

Konvertibilnost američkih dolara u zlato – zlatni standard – nikada se nije vratio.

Od 1971. godine, čitav globalni monetarni sistem pokreće se tradicionalnim “fiat” valutama: poverenjem u vladine institucije da održavaju valutni sistem.

Većina valuta podržana je kombinacijom duga njihove vlade i drugih tradicionalnih valuta poput dolara i evra. Papirne valute više nisu podržane zlatom, imovinom koja je više od 5000 godina služila kao težak novac.

Danas vas vlade prisiljavaju da plaćate porez u njihovoj valuti i manipulišu saznanjima oko novca kako bi osigurale da potražnja za njihovom valutom ostane velika.

To im omogućava da neprestano štampaju više valuta, da bi je potrošili na vladine projekte, uzrokujući inflaciju cena koja jede i smanjuje bogatstvo i plate.

Američka vlada sada prodaje državne obveznice (dugove), poznate kao obveznice Trezora SAD, eng. US Treasuries, komercijalnim bankama u zamenu za američke dolare.

Vlada koristi te dolare za finansiranje svog budžetskog deficita. Komercijalne banke prodaju mnoge obveznice Trezora SAD, koje su kupile, američkoj centralnoj banci, Federalnim Rezervama.

Federalne rezerve plaćaju komercijalnim bankama sveže štampanim novcem “pomoću računara i upisivanjem količine na račun”, kako je rekao bivši predsednik Fed-a Ben Bernanke.

Ove komercijalne banke često zarađuju samo kupujući obveznice Trezora SAD od države i prodajući ih centralnoj banci. Kupujte nisko, prodajte visoko.

Centralne banke ovaj proces kupovine državnog duga – odnosno pozajmljivanja novca državi – nazivaju operacijama otvorenog tržišta.

Kada centralna banka odjednom kupi velike iznose duga, oni to nazivaju kvantitativnim ublažavanjem. Centralne banke javno najavljuju kupovinu državnog duga, ali vrlo malo ljudi razume šta to zapravo znači.

Euro, jen i svaka druga valuta koja se danas koristi funkcionišu slično kao američki dolar.

Da li će SAD ikada vratiti svoj nacionalni dug? Neobična stvar u vezi sa državnim dugom SAD-a je ta što vlada poseduje štampariju potrebnu za njegovu otplatu.

Kao rezultat toga, kada vlada duguje novac, oni samo pozajme još više novca da bi otplatile taj dug, povećavajući nacionalni dug.

Ako vam ovo zvuči kao Ponzijeva piramidalna šema, to je zato što ona to i jeste – najveća Ponzijeva šema u istoriji. Kao i svaka Ponzijeva šema, nastaviće se sve dok su ljudi koji kupuju Ponzijevu šemu budu uvereni da će im biti plaćeno nazad.

Ako ljudi i nacije prestanu da se zadužuju i koriste američke dolare jer nemaju poverenja u američku vladu ili vide da cena robe raste (tj. dolar postaje sve manje vredan), potražnja za dolarom će opadati, što će izazvati začaranu spiralu.

Ova spirala često završi u hiperinflaciji, kao što smo videli u novijoj istoriji sa Jugoslavijom, Venecuelom, Argentinom, Zimbabveom i mnogim drugim državama.

Ovo je način kako funkcioniše novac na vašem bankovnom računu. Novac svake nacije na svetu pati od istih problema kao i perle i novčanice u pričama o Njutoniji i Kejnslandu.

Kako banke i vlade kradu tvoj novac?

Tokom vekova, stigli smo do monetarnog sistema u kojem banke i vlade mogu da štampaju novu valutu za finansiranje svojih operacija i svojih prijatelja u zločinu, dok kradu bogatstvo svojih građana.

Šta će se desiti sa svetom kada novac bude mogao da štampa svaki narod na planeti?

• Bogatstvo onih koji su blizu pravljenja nove valute se povećava
• Vlada i politički povlašćena klasa ljudi, imaju pristup novoštampanom novcu pre svih ostalih, pa mogu da ga potroše pre nego što cene porastu. Na ovaj efekat pokazao je ekonomista Richard Cantillon sredinom 1700-ih i poznat je kao Cantillonov Efekat.
• Cena robe raste (poznato kao inflacija
• Ne raste sve roba istovremeno u ceni. Roba blizu mesta gde se proizvodi nova valuta – finansijski sektor i vlada – prva raste, i odatle uzrokuje efekt talasa na cene.
• Inflacija se često predstavlja kao promena cene potrošačke korpe, poznata kao Indeks Potrošačkih Cena, eng. Consumer Price Index (CPI). Vlada ima alate za manipulisanje ovim brojem kako bi osigurala da se ona čini niskom i stabilnom, kao što je objašnjeno u našem članku o inflaciji.
• Finansijska imovina često primećuje ogromnu inflaciju, ali bankari to ne nazivaju inflacijom – oni kažu da naša ekonomija cveta! Nakon što su američke Federalne rezerve učetvorostručile ponudu američkih dolara u šest godina nakon finansijske krize 2008. godine, banke koje su dobile te nove dolare, kupile su akcije i obveznice, stvarajući ogroman balon u cenama ove imovine.
• Štednja i životni standard stanovništva se smanjuju
• Plate su jedna od poslednjih “cena” u ekonomiji koja se prilagođava, jer se često povećavaju samo jednom godišnje. U međuvremenu, cene dnevnih potrepština te osobe koja zaradjuje platu neprestano rastu kako novi novac kruži ekonomijom.
• Najviše su pogođeni oni koji žive od plate do plate – a to je 70% Amerikanaca.
• Razlike u prihodima između bogatih i siromašnih se povećavaju, kao što se vidi na grafikonu ispod.

*Koncentracija dohotka na vrhu naglo je porasla od 1970-ih

Zašto i dalje imamo isti monetarni sistem?

Ako ovaj sistem bogate još više obogaćuje, a siromašne još više osiromašuje, dovodeći do političke nestabilnosti, zašto ga onda ne bismo promenili?

Najveći razlog zašto se ništa ne menja je verovatno to što puno toga ne znamo o samom sistemu. Svi svakodnevno koristimo valute svojih vlada, ali većina nas ne razume kako sistem funkcioniše i šta on čini našim društvima.

Obrazovni sistem, mediji i finansijski stručnjaci neprestano nam govore da je monetarni sistem previše komplikovan da bi ga normalni ljudi razumeli. Mnogi od nas se zato i ne trude da pokušaju.

Još nekoliko razloga zašto ovaj sistem nastavlja da opstaje:

• Mnogo je ljudi koji imaju direktnu korist od štampanja novog novca.
• Ti ljudi ne žele nikakve promene i bore se da zadrže tu moć.
• Nacionalne valute su često pogodne
• Kreditne kartice, online bankarstvo i još mnogo toga čine upravljanje nacionalnim valutama i njihovo trošenje lakim i jednostavnim.
• Građani moraju da plaćaju porez u svojoj nacionalnoj valuti
• To stvara potražnju za tom valutom od svih građana, povećavajući njenu vrednost.
• Glavna međunarodna tržišta, poput nafte, denominirana su u dolarima.
• Nafta je potrebna svakoj zemlji na planeti, ali pošto mnogi ne mogu da je proizvode, moraju da je kupuju na međunarodnim berzama. Od 1970-ih na ovim berzama gotovo sva nafta se prodaje za dolare, što stvara potražnju za dolarima. Da bi se odmaknule od ovog sistema, zemlje bi trebale da pronađu novu valutu ili robu za trgovinu naftom, što zahteva vreme i rizike.
• Nije postojala dobra alternativa
• Uz globalnu ekonomiju u realnom vremenu, naš sistem digitalnog bankarstva koji koristi nacionalne valute je pogodan. Transakcija u tvrdom novcu poput zlata bila bi previše nezgrapna za današnji svet. Digitalna valuta pod nazivom Bitcoin, predstavljena 2009. godine, je rastuća alternativa koja nudi čvrst novac koji se kreće brzinom interneta.

Šta je novac, i zašto trebate da brinete?

Novac je alat koji olakšava razmenu dobara. Kao i svako drugo dobro, novac se pridržava zakona ponude i potražnje – povećanje potražnje povećaće njegovu vrednost, a povećanje ponude smanjiće njegovu vrednost.

Na ovaj način novac se ne razlikuje od kuće ili piletine. Međutim, velika prodajnost novca znači da je potražnja za njim uvek velika. Kao rezultat, novac mora biti težak za proizvodnju (a samim tim i ograničen u ponudi) ili će ga onaj ko ga može napraviti, stvoriti toliko, da vremenom više neće služiti kao zaliha vrednosti. Uskoro će izgubiti svoje funkcije kao sredstvo razmene i obračunske jedinice.

Najbolji novac u datoj ekonomiji je onaj koji se najslobodnije kreće – svi ga žele, lako je obaviti transakcije sa njim i koji sa vremenom dobro drži svoju vrednost. Nijedan novac nije savršen u svemu ovome, a neki ističu jednu funkciju novca na štetu drugih.

Iako se istorija ne ponavlja, ona se rimuje, a usponi i padovi monetarnih sistema imaju jasne ritmove. Uspon i pad monetarnog sistema često sledi opšti obrazac koji smo videli u pričama o agri perlama i Kejnslandu: pojavljuje se odredjenji oblik novca koji pomaže ljudima da efikasnije trguju i štede, ali na kraju gubi na vrednosti kada neko shvati kako da ga jeftino stvori u velikoj količini. Međutim, tokom dugog perioda vremena, monetarni sistemi su se poboljšali u sve tri funkcije novca.

Na primer, zlato je tokom vremena dobro služilo kao zaliha vrednosti. Međutim, naša međusobno povezana ekonomija ne bi mogla efikasno da funkcioniše ako bi trebalo da fizičko zlato zamenimo robom i uslugama. Mnogo je lakše kretati se na papirnom i digitalnom novcu, ali istorija nam govori da su vlade i bankari iskoristili ove oblike novca za krađu bogatstva putem inflacije.

Današnji globalni monetarni sistem je vrlo zgodan, a digitalna plaćanja i kreditne kartice olakšavaju trošenje novca. Ovo skriva stalnu inflaciju koja nagriza vrednost svake jedinice novca i dovodi do sve većeg jaza u bogatstvu.

Nadam se da je ovaj članak proširio vaše razumevanje novca i njegove uloge u društvu. Ovo je samo početak svega što treba istražiti o novcu: za kasnije su sačuvane teme o inflaciji, kamatnim stopama, pozajmljivanju, poslovnim ciklusima i još mnogo toga.

Efikasnija Ušteda Novca

Možda se pitate kako zaštititi svoju štednju kada svaki oblik često korišćenog novca i investicija pati od inflacije ponude – koja umanjuje vrednost i prenosi bogatstvo onima koji mogu da stvore novac ili investiciju. Možda se čini da se ništa na planeti danas ne može kvalifikovati kao ‘težak’ novac, ali dve stvari ipak ostaju: zlato i njegov noviji rođak Bitcoin. Obe ove stvari je neverovatno teško proizvesti, a jedna od njih se kreće brzinom interneta i može se čuvati u vašem mozgu.

Warning: 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.

I want to see Nostr succeed. If you can think of a way I can help make that happen, I’m open to it. I’d like your suggestions.

My schedule’s shifting soon, and I could volunteer a few hours a week to a Nostr project. I won’t have more total time, but how I use it will change.

Why help? I care about freedom. Nostr’s one of the most powerful freedom tools I’ve seen in my lifetime. If I believe that, I should act on it.

I don’t care about money or sats. I’m not rich, I don’t have extra cash. That doesn’t drive me—freedom does. I’m volunteering, not asking for pay.

I’m not here for clout. I’ve had enough spotlight in my life; it doesn’t move me. If I wanted clout, I’d be on Twitter dropping basic takes. Clout’s easy. Freedom’s hard. I’d rather help anonymously. No speaking at events—small meetups are cool for the vibe, but big conferences? Not my thing. I’ll never hit a huge Bitcoin conference. It’s just not my scene.

That said, I could be convinced to step up if it’d really boost Nostr—as long as it’s legal and gets results.

In this space, I’d watch for social engineering. I watch out for it. I’m not here to make friends, just to help. No shade—you all seem great—but I’ve got a full life and awesome friends irl. I don’t need your crew or to be online cool. Connect anonymously if you want; I’d encourage it.

I’m sick of watching other social media alternatives grow while Nostr kinda stalls. I could trash-talk, but I’d rather do something useful.

Skills? I’m good at spotting social media problems and finding possible solutions. I won’t overhype myself—that’s weird—but if you’re responding, you probably see something in me. Perhaps you see something that I don’t see in myself.

If you need help now or later with Nostr projects, reach out. Nostr only—nothing else. Anonymous contact’s fine. Even just a suggestion on how I can pitch in, no project attached, works too. 💜

Creeps or harassment will get blocked or I’ll nuke my simplex code if it becomes a problem.

背景：WhatsApp的号码验证与运营商合作关系

作为一款基于手机号码注册的即时通信应用，WhatsApp的账号验证严重依赖全球电信运营商提供的短信或电话服务。这意味着，当用户注册或在新设备登录WhatsApp时，WhatsApp通常会向用户的手机号码发送SMS短信验证码或发起语音电话验证。这一流程利用了传统电信网络的基础设施，例如通过SS7（信令系统7）协议在全球范围内路由短信和电话securityaffairs.com。换句话说，WhatsApp把初始账户验证的安全性建立在电信运营商网络之上。然而，这种依赖关系也带来了隐患：攻击者可以利用电信网络的漏洞来拦截验证码。例如，研究人员早在2016年就演示过利用SS7协议漏洞拦截WhatsApp和Telegram的验证短信，从而劫持用户账户的攻击方法securityaffairs.com。由于SS7协议在全球范围内连接各国运营商，一个运营商的安全缺陷或恶意行为都可能被不法分子利用来获取他网用户的短信验证码securityaffairs.com。正因如此，有安全专家指出，仅依赖短信验证不足以保障账户安全，WhatsApp等服务提供商需要考虑引入额外机制来核实用户身份securityaffairs.com。

除了技术漏洞，基于电信运营商的验证还受到各地政策和网络环境影响。WhatsApp必须与全球各地运营商“合作”，才能将验证码送达到用户手机。然而这种“合作”在某些国家可能并不顺畅，典型例子就是中国。在中国大陆，国际短信和跨境电话常受到严格管控，WhatsApp在发送验证码时可能遭遇拦截或延迟sohu.com。因此，理解WhatsApp在中国的特殊联网和验证要求，需要将其全球验证机制与中国的电信政策和网络审查环境联系起来。下文将深入探讨为什么在中国使用WhatsApp进行号码验证时，必须开启蜂窝移动数据，并分析其中的技术逻辑和政策因素。

中国环境下的特殊问题：为何必须开启蜂窝数据？

中国的网络审查与封锁： WhatsApp自2017年起就在中国大陆遭遇严格封锁。起初，WhatsApp在华的服务受到**“GFW”（防火长城）**的部分干扰——例如曾一度只能发送文本消息，语音、视频和图片消息被封锁theguardian.com。到2017年下半年，封锁升级，很多用户报告在中国完全无法使用WhatsApp收发任何消息theguardian.com。中国官方将WhatsApp与Facebook、Telegram等西方通信平台一同屏蔽，视作对国家网络主权的挑战theguardian.com。鉴于此，在中国境内直接访问WhatsApp的服务器（无论通过Wi-Fi还是本地互联网）都会被防火长城所阻断。即使用户收到了短信验证码，WhatsApp客户端也无法在没有特殊连接手段的情况下与服务器完成验证通信。因此，单纯依赖Wi-Fi等本地网络环境往往无法完成WhatsApp的注册或登陆。很多用户经验表明，在中国使用WhatsApp时需要借助VPN等工具绕过审查，同时尽可能避免走被审查的网络路径sohu.com。

强制Wi-Fi热点与连接策略： 除了国家级的封锁，用户所连接的局域网络也可能影响WhatsApp验证。许多公共Wi-Fi（如机场、商场）采取强制门户认证（captive portal），用户需登录认证后才能上网。对此，WhatsApp在客户端内置了检测机制，当发现设备连入这类强制Wi-Fi热点而无法访问互联网时，会提示用户忽略该Wi-Fi并改用移动数据faq.whatsapp.com。WhatsApp要求对此授予读取Wi-Fi状态的权限，以便在检测到被拦截时自动切换网络faq.whatsapp.com。对于中国用户来说，即便所连Wi-Fi本身联网正常，由于GFW的存在WhatsApp依然可能视之为“不通畅”的网络环境。这也是WhatsApp官方指南中强调：如果Wi-Fi网络无法连接WhatsApp服务，应直接切换到手机的移动数据网络faq.whatsapp.com。在中国，由于本地宽带网络对WhatsApp的封锁，蜂窝数据反而成为相对可靠的通道——尤其在搭配VPN时，可以避开本地ISP的审查策略，实现与WhatsApp服务器的通信sohu.com。

国际短信的运营商限制： 使用移动数据还有助于解决短信验证码接收难题。中国的手机运营商出于防垃圾短信和安全考虑，默认对国际短信和境外来电进行一定限制。许多中国用户发现，注册WhatsApp时迟迟收不到验证码短信，原因可能在于运营商将来自国外服务号码的短信拦截或过滤sohu.com。例如，中国移动默认关闭国际短信接收，需要用户主动发送短信指令申请开通sohu.com。具体而言，中国移动用户需发送文本“11111”到10086（或10085）来开通国际短信收发权限；中国联通和电信用户也被建议联系运营商确认未屏蔽国际短信sohu.com。若未进行这些设置，WhatsApp发送的验证码短信可能根本无法抵达用户手机。在这种情况下，WhatsApp提供的备用方案是语音电话验证，即通过国际电话拨打用户号码并播报验证码。然而境外来电在中国也可能遭到运营商的安全拦截，特别是当号码被认为可疑时zhuanlan.zhihu.com。因此，中国用户经常被建议开启手机的蜂窝数据和漫游功能，以提高验证码接收的成功率sohu.com。一方面，开启数据漫游意味着用户准备接受来自境外的通信（通常也包含短信/电话）；另一方面，在数据联网的状态下，WhatsApp可以尝试通过网络直接完成验证通信，从而减少对SMS的依赖。

移动数据的网络路径优势： 在实际案例中，一些中国WhatsApp用户报告仅在开启蜂窝数据的情况下才能完成验证。这可能归因于蜂窝网络和宽带网络在国际出口上的差异。中国移动、联通等运营商的移动数据可能走与宽带不同的网关路由，有时对跨境小流量的拦截相对宽松。此外，WhatsApp在移动数据环境中可以利用一些底层网络特性。例如，WhatsApp可能通过移动网络发起某些专用请求或利用运营商提供的号码归属地信息进行辅助验证（虽然具体实现未公开，但这是业界讨论的可能性）。总之，在中国特殊的网络环境下，开启蜂窝数据是确保WhatsApp验证流程顺利的重要一步。这一步不仅是为了基本的互联网连接，也是为了绕开种种对国际短信和应用数据的拦截限制，从而与WhatsApp的全球基础设施建立必要的通讯。

PDP Context与IMSI：移动网络验证的技术细节

要理解为什么移动数据对WhatsApp验证如此关键，有必要了解移动通信网络中的一些技术细节，包括PDP Context和IMSI的概念。

PDP Context（分组数据协议上下文）： 当手机通过蜂窝网络使用数据（如4G/5G上网）时，必须先在运营商核心网中建立一个PDP上下文。这实际上就是申请开启一个数据会话，运营商将为设备分配一个IP地址，并允许其通过移动核心网访问互联网datascientest.com。PDP上下文包含了一系列参数（例如APN接入点名称、QoS等级等），描述该数据会话的属性datascientest.comdatascientest.com。简单来说，激活蜂窝数据就意味着创建了PDP上下文，设备获得了移动网络网关分配的IP地址，可以收发数据包。对于WhatsApp验证而言，只有在建立数据连接后，手机才能直接与WhatsApp的服务器交换数据，例如提交验证码、完成加密密钥协商等。如果仅有Wi-Fi而蜂窝数据关闭，且Wi-Fi环境无法连通WhatsApp服务器，那么验证过程将陷入停滞。因此，在中国场景下，开启蜂窝数据（即建立PDP数据通路）是WhatsApp客户端尝试绕过Wi-Fi限制、直接通过移动网络进行验证通信的前提faq.whatsapp.comsohu.com。值得一提的是，PDP Context的建立也表明手机在运营商网络上处于活跃状态，这对于某些验证机制（比如后述的闪信/闪呼）来说至关重要。

IMSI与MSISDN： IMSI（国际移动用户标识）和MSISDN（移动用户号码，即手机号码）是运营商网络中两个密切相关但不同的标识。IMSI是存储在SIM卡上的一串唯一数字，用于在移动网络中标识用户身份netmanias.com。当手机接入网络时，它向运营商提供IMSI以进行鉴权，运营商据此知道“是哪张SIM”的请求netmanias.com。而MSISDN则是我们平常说的手机号，用于在语音通话和短信路由中定位用户，也存储在运营商的HLR/HSS数据库中netmanias.com。运营商通过IMSI<->MSISDN的对应关系，将来自全球的短信/电话正确路由到用户手机上。WhatsApp的验证短信或电话本质上就是通过目标号码(MSISDN)寻找所属运营商网络，由该网络根据IMSI定位用户终端。一般情况下，WhatsApp应用并不直接接触IMSI这种信息，因为IMSI属于运营商网络的内部标识。然而，IMSI的存在仍然对安全产生影响。例如，**SIM卡交换（SIM Swap）**欺诈发生时，攻击者获得了受害者号码的新SIM卡，新SIM卡会有不同的IMSI，但MSISDN保持原号码不变。运营商会将原号码映射到新的IMSI，这样验证码短信就发送到了攻击者手中的SIM上。对WhatsApp而言，除非有机制检测IMSI变动，否则无法察觉用户号码背后的SIM已被盗换。部分应用在检测到SIM变化时会提示用户重新验证，这需要读取设备的IMSI信息进行比对。然而，在现代智能手机中，获取IMSI通常需要特殊权限，WhatsApp并未明确说明它有此类检测。因此，从WhatsApp角度，IMSI更多是网络侧的概念，但它提醒我们：电信级身份验证依赖于SIM的有效性。只有当正确的IMSI在网络注册、并建立了PDP数据上下文时，WhatsApp的后台服务才能确认该SIM对应的号码目前“在线”，进而可靠地发送验证信号（短信或电话）到该设备。

移动网络的信号辅助验证： 有观点认为，一些OTT应用可能利用移动网络提供的附加服务来辅助号码验证。例如，某些运营商提供号码快速验证API，当应用检测到设备在移动数据网络中时，可以向特定地址发起请求，由运营商返回当前设备的号码信息（通常通过已经建立的PDP通道）。Google等公司在部分国家与运营商合作过类似服务，实现用户免输入验证码自动完成验证。但就WhatsApp而言，没有公开证据表明其使用了运营商提供的自动号码识别API。即便如此，WhatsApp鼓励用户保持移动网络在线的做法，隐含的意义之一可能是：当手机处于蜂窝网络且数据畅通时，验证码通过率和验证成功率都会显著提升。这既包括了物理层面短信、电话能否送达，也涵盖了数据层面应用和服务器能否互通。

Flash Call机制：WhatsApp验证的新方案

针对传统SMS验证码容易被拦截、延迟以及用户体验不佳的问题，WhatsApp近年来引入了一种Flash Call（闪呼）验证机制fossbytes.com。所谓闪呼，即应用在用户验证阶段向用户的手机号发起一个非常短暂的来电：用户无需真正接听，WhatsApp会自动结束这通电话，并根据通话记录来确认是否拨通fossbytes.com。

原理与流程： 当用户选择使用闪呼验证（目前主要在Android设备上可用），WhatsApp会请求权限访问用户的通话记录fossbytes.com。随后应用拨打用户的号码，一般是一个预先设定的特定号码或号码段。由于WhatsApp后台知道它拨出的号码及通话ID，只要该未接来电出现在用户手机的通话日志中，应用即可读取并匹配最后一通来电的号码是否符合验证要求，从而确认用户持有这个号码fossbytes.com。整个过程用户无需手动输入验证码，验证通话在数秒内完成。相比6位数字短信验证码需要用户在短信和应用间切换输入，闪呼方式更加快捷无缝fossbytes.com。

优缺点分析： 闪呼验证的优势在于速度快且避免了SMS可能的延迟或拦截。一些分析指出闪呼将成为取代SMS OTP（一次性密码）的新趋势，Juniper Research预测2022年用于验证的闪呼次数将从2021年的六千万猛增到五十亿次subex.comglobaltelcoconsult.com。对于WhatsApp这样全球用户庞大的应用，闪呼可以节约大量SMS网关费用，并绕开部分运营商对国际SMS的限制。然而，闪呼也有局限：fossbytes.com首先，iOS设备由于系统安全限制，应用无法访问通话记录，因此iPhone上无法使用闪呼验证fossbytes.com。这意味着苹果用户仍需使用传统短信验证码。其次，为实现自动匹配来电号码，用户必须授予读取通话记录的权限，这在隐私上引发一些担忧fossbytes.comfossbytes.com。WhatsApp声称不会将通话记录用于验证以外的用途，号码匹配也在本地完成fossbytes.com，但考虑到母公司Meta的隐私争议，部分用户依然顾虑。第三，闪呼验证依赖语音通话路线，同样受制于电信网络质量。如果用户所处网络无法接通国际来电（比如被运营商拦截境外短振铃电话），闪呼也无法成功。此外，从运营商角度看，闪呼绕过了A2P短信计费，可能侵蚀短信营收，一些运营商开始研究识别闪呼流量的策略wholesale.orange.com。总体而言，闪呼机制体现了WhatsApp希望减轻对短信依赖的努力，它在许多国家提升了验证体验，但在中国等特殊环境，其效果仍取决于本地语音网络的开放程度。值得注意的是，中国运营商对于境外电话，尤其是这种**“零响铃”未接来电**也有防范措施，中国电信和联通用户就被建议如需接收海外来电验证，应联系客服确保未拦截海外来电hqsmartcloud.com。因此，即便WhatsApp支持闪呼，中国用户若未开启移动语音漫游或运营商许可，仍然难以通过此途径完成验证。

与SIM Swap安全性的关系： 从安全角度看，闪呼并未实质提升抵御SIM交换攻击的能力。如果攻击者成功将受害者的号码转移至自己的SIM卡上（获取新IMSI），那么无论验证码以短信还是闪呼方式发送，都会到达攻击者设备。闪呼机制能防御的是部分恶意拦截短信的行为（如恶意网关或木马读取短信），但对社工换卡没有太大帮助。WhatsApp早已提供两步验证（即设置6位PIN码）供用户自行启用，以防号码被他人重新注册时需要额外密码。然而大量用户未开启该功能。因此，闪呼更多是从用户体验和成本出发的改良，而非针对高级别攻击的防护机制。正如前文所述，真正要防御SIM Swap和SS7漏洞等系统性风险，依赖运营商的号码验证本身就是薄弱环节，需要引入更高级的身份认证手段。

SIM卡交换攻击的风险与运营商信任问题

WhatsApp和Telegram一类基于手机号认证的应用普遍面临一个安全挑战：手机号码本身并非绝对安全的身份凭证。攻击者可以通过一系列手段取得用户的号码控制权，其中SIM交换（SIM Swap）是近年高发的欺诈手法。SIM Swap通常由不法分子冒充用户，诱骗或贿赂运营商客服将目标号码的服务转移到攻击者的新SIM卡上keepnetlabs.com。一旦成功，所有发往该号码的短信和电话都转由攻击者接收，原机主的SIM卡失效。对于依赖短信/电话验证的应用来说，这意味着攻击者可以轻易获取验证码，从而重置账户并登录。近年来全球SIM Swap案件呈上升趋势，许多在线服务的账号被此攻破rte.ie。

WhatsApp并非未知晓此风险。事实上，WhatsApp在其帮助中心和安全博客中多次提醒用户开启两步验证PIN，并强调绝不向他人透露短信验证码。然而，从系统设计上讲，WhatsApp仍将信任根基放在运营商发送到用户手机的那串数字验证码上。一旦运营商端的安全被绕过（无论是内部员工作恶、社工欺诈，还是SS7网络被黑客利用securityaffairs.com），WhatsApp本身无法辨别验证码接收者是否是真正的用户。正如安全研究所Positive Technologies指出的那样，目前主要的即时通讯服务（包括WhatsApp和Telegram）依赖SMS作为主要验证机制，这使得黑客能够通过攻击电信信令网络来接管用户账户securityaffairs.com。换言之，WhatsApp被迫信任每一个参与短信/电话路由的运营商，但这个信任链条上任何薄弱环节都可能遭到利用securityaffairs.com。例如，在SIM Swap攻击中，运营商本身成为被欺骗的对象；而在SS7定位拦截攻击中，全球互联的电信网成为攻击面。在中国的场景下，虽然主要威胁来自审查而非黑客，但本质上仍是WhatsApp无法完全掌控电信网络这一事实所导致的问题。

应对这些风险，WhatsApp和Telegram等采用了一些弥补措施。除了提供用户自行设定的二次密码，两者也开始探索设备多因子的概念（如后文Telegram部分所述，利用已有登录设备确认新登录）。然而，对绝大多数首次注册或更换设备的用户来说，传统的短信/电话验证仍是唯一途径。这就是为什么在高安全需求的行业中，SMS OTP正逐渐被视为不充分securityaffairs.com。监管机构和安全专家建议对涉敏感操作采用更强验证，如专用身份应用、硬件令牌或生物识别等。WhatsApp作为大众通信工具，目前平衡了易用性与安全性，但其依赖电信运营商的验证模式在像中国这样特殊的环境下，既遇到政策阻碍，也隐藏安全短板。这一点对于决策制定者评估国外通信应用在华风险时，是一个重要考量：任何全球运营商合作机制，在中国境内都可能因为**“最后一公里”由中国运营商执行**而受到影响。无论是被拦截信息还是可能的监控窃听，这些风险都源自于底层通信网的控制权不在应用服务商手中。

Telegram登录机制的比较

作为对比，Telegram的账号登录机制与WhatsApp类似，也以手机号码为主要身份标识，但在具体实现上有一些不同之处。

多设备登录与云端代码： Telegram从设计上支持多设备同时在线（手机、平板、PC等），并将聊天内容储存在云端。这带来的一个直接好处是：当用户在新设备上登录时，Telegram会优先通过已登录的其他设备发送登录验证码。例如，用户尝试在电脑上登录Telegram，Telegram会在用户手机上的Telegram应用里推送一条消息包含登录码，而不是立即发短信accountboy.comaccountboy.com。用户只需在新设备输入从老设备上收到的代码即可完成登录。这种机制确保了只要用户至少有一个设备在线，就几乎不需要依赖运营商短信。当然，如果用户当前只有一部新设备（例如换了手机且旧设备不上线），Telegram才会退而求其次，通过SMS发送验证码到手机号。同时，Telegram也允许用户选择语音电话获取验证码，类似于WhatsApp的语音验证。当用户完全无法收到SMS时（比如在中国这种场景），语音呼叫常常比短信更可靠seatuo.com。

两步验证密码： 与WhatsApp一样，Telegram提供可选的两步验证密码。当启用此功能后，即使拿到短信验证码，仍需输入用户设置的密码才能登录账户quora.com。这对抗SIM Swap等攻击提供了另一层防线。不过需要指出，如果用户忘记了设置的Telegram密码且没有设置信任邮箱，可能会永久失去账号访问，因此开启该功能在中国用户中接受度一般。

登录体验与安全性的取舍： Telegram的登录流程在用户体验上更加灵活。多设备下无需每次都收验证码，提高了便利性。但从安全角度看，这种“信任已有设备”的做法也有隐患：如果用户的某个设备落入他人之手并未及时登出，那么该人有可能利用该设备获取新的登录验证码。因此Telegram会在应用中提供管理活动会话的功能，用户可随时查看和撤销其它设备的登录状态telegram.org。总体而言，Telegram和WhatsApp在初始注册环节同样依赖短信/电话，在这一点上，中国的网络环境对两者影响相似：Telegram在中国同样被全面封锁，需要VPN才能使用，其短信验证码发送也会受到运营商限制。另外，Telegram曾在2015年因恐怖分子利用该平台传递信息而被中国当局重点关注并屏蔽，因此其国内可达性甚至比WhatsApp更低。许多中国用户实际使用Telegram时，通常绑定国外号码或通过海外SIM卡来收取验证码，以绕开国内运营商的限制。

差异总结： 简而言之，Telegram在登录验证机制上的主要优势在于已有会话协助和云端同步。这使得老用户换设备时不依赖国内短信通道即可登录（前提是原设备已登录并可访问）。WhatsApp直到最近才推出多设备功能，但其多设备模式采用的是端到端加密设备链路，需要主手机扫码授权，而非像Telegram那样用账号密码登录其它设备。因此WhatsApp仍然强绑定SIM卡设备，首次注册和更换手机号时逃不开运营商环节。安全方面，两者的SMS验证所面临的系统性风险（如SS7攻击、SIM Swap）并无本质区别，都必须仰仗运营商加强对核心网络的保护，以及用户自身启用附加验证措施securityaffairs.comkeepnetlabs.com。

结论

对于希望在中国使用WhatsApp的用户来说，“开启蜂窝数据”这一要求背后体现的是技术与政策交织的复杂现实。一方面，蜂窝数据承载着WhatsApp与其全球服务器通信的关键信道，在中国的受限网络中提供了相对可靠的出路faq.whatsapp.comsohu.com。另一方面，WhatsApp的号码验证机制深深植根于传统电信体系，必须经由全球运营商的“协作”才能完成用户身份确认securityaffairs.com。而在中国，这种协作受到防火长城和运营商政策的双重阻碍：国际短信被拦截、国际数据被阻断。为克服这些障碍，WhatsApp既采取了工程上的应对（如检测强制Wi-Fi并提示使用移动网络faq.whatsapp.com），也引入了诸如闪呼验证等新方案以减少对短信的依赖fossbytes.com。但从根本上说，只要注册流程离不开手机号码，这种与电信运营商的捆绑关系就无法割舍。由此带来的安全问题（如SIM Swap和信令网络漏洞）在全球范围内敲响警钟securityaffairs.comkeepnetlabs.com。

对于从事安全研究和政策评估的人士，这篇分析揭示了WhatsApp在中国遇到的典型困境：技术系统的全球化与监管环境的本地化冲突。WhatsApp全球统一的验证框架在中国水土不服，不得不通过额外的设置和手段来“曲线救国”。这既包括让用户切换网络、配置VPN等绕过审查，也包括思考未来是否有必要采用更安全独立的验证方式。相比之下，Telegram的机制给出了一种启示：灵活运用多设备和云服务，至少在一定程度上降低对单一短信渠道的依赖。然而，Telegram自身在中国的处境表明，再优雅的技术方案也难以直接对抗高强度的网络封锁。最终，无论是WhatsApp还是Telegram，要想在受限环境下可靠运作，都需要技术与政策的双管齐下：一方面提高验证与登录的安全性和多样性，另一方面寻求运营商和监管层面的理解与配合。

综上所述，WhatsApp要求中国用户开启蜂窝数据并非偶然的臆想，而是其全球运营商合作验证机制在中国受阻后的务实选择。这一要求折射出移动通信应用在跨境运营中面临的挑战，也提醒我们在设计安全策略时必须考虑底层依赖的信任假设。对于个人用户，最实际的建议是在使用此类应用时提前了解并遵循这些特殊设置（如开通国际短信、启用数据漫游），并善用应用自身的安全功能（如两步验证）来保护账户免遭社工和网络攻击keepnetlabs.com。对于监管和运营商，则有必要权衡安全审查与用户便利之间的平衡，在可控范围内为可信的全球服务留出技术通道。在全球通信愈加融合的时代，WhatsApp的中国验证问题或许只是一个缩影，背后涉及的既有网络安全考量，也有数字主权与国际合作的议题，值得持续深入研究和关注。

Vivek Ramaswamy’s company bets on distressed bitcoin claims as its Bitcoin treasury strategy moves forward.

Strive Enterprises, an asset management firm co-founded by Vivek Ramaswamy, is exploring the acquisition of distressed bitcoin claims, with particular interest in around 75,000 BTC tied to the Mt. Gox bankruptcy estate. This move is part of the company’s broader strategy to build a Bitcoin treasury ahead of its planned merger with Asset Entities.

According to a document filed on May 20 with the Securities and Exchange Commission, Strive has partnered with 117 Castell Advisory Group to “identify and evaluate” distressed Bitcoin claims with confirmed legal judgments. Among these are approximately 75,000 BTC connected to Mt. Gox, with an estimated market value of $8 billion at current prices.

Essentially, Strive aims to acquire rights to bitcoins currently tied up in legal disputes, which can be purchased at a discount by those willing to take on the risk and wait for eventual recovery.

In a post on X, Strive’s CFO, Ben Pham, stated:

“Strive intends to use all available mechanisms, including novel financial strategies not used by other Bitcoin treasury companies, to maximize its exposure to the asset.”

The company also plans to buy cash at a discount by merging with publicly traded companies holding more cash than their stock value, using the excess funds to purchase additional Bitcoin.

Mt. Gox, the exchange that collapsed in 2014, is currently in the process of repaying creditors, with a deadline set for October 31, 2025.

In its SEC filing, Strive declared:

“This strategy is intended to allow Strive the opportunity to purchase Bitcoin exposure at a discount to market price, enhancing Bitcoin per share and supporting its goal of outperforming Bitcoin over the long run.”

At the beginning of May, Strive announced its merger plan with Asset Entities, a deal that would create the first publicly listed asset management firm focused on Bitcoin. The resulting company aims to join the growing number of firms adopting a Bitcoin treasury strategy.

The corporate treasury trend

Strive’s initiative to accumulate bitcoin mirrors that of other companies like Strategy and Japan’s Metaplanet. On May 19, Strategy, led by Michael Saylor, announced the purchase of an additional 7,390 BTC for $764.9 million, raising its total holdings to 576,230 BTC. On the same day, Metaplanet revealed it had acquired another 1,004 BTC, increasing its total to 7,800 BTC.

The post Bitcoin in Strive’s sights: 75,000 BTC from Mt. Gox among its targets appeared first on Atlas21.

Explanation:

Error Handling for contentIds:
    Added checks to ensure contentIds is defined before using it.
    If contentIds is still loading or an error occurred while fetching contentIds, handle these cases appropriately by returning empty arrays or logging the error.

Loading State Check:
    If contentIds is still loading, the fetchResourcesFromNDK function will return an empty array or indicate a loading state.

Error Check:
    If there's an error in fetching contentIds, log the error and return an empty array to avoid breaking the application flow.

Apply the Same Handling to useCoursesQuery

Similarly, you can apply the same error handling and checks in the useCoursesQuery function:

```js import { useState, useEffect } from 'react'; import { useQuery } from '@tanstack/react-query'; import { useNDKContext } from '@/context/NDKContext'; import { useContentIdsQuery } from '@/hooks/apiQueries/useContentIdsQuery';

const AUTHOR_PUBKEY = process.env.NEXT_PUBLIC_AUTHOR_PUBKEY;

export function useCoursesQuery() { const [isClient, setIsClient] = useState(false);

const { contentIds, contentIdsLoading, contentIdsError, refetchContentIds } = useContentIdsQuery();
const ndk = useNDKContext();

useEffect(() => {
    setIsClient(true);
}, []);

useEffect(() => {
    refetchContentIds();
}, [refetchContentIds]);

const hasRequiredProperties = (event) => {
    if (!contentIds) {
        return false;
    }
    const hasCourseTag = event.tags.some(([tag, value]) => tag === "t" && value === "course");
    const hasId = contentIds.includes(event.id);
    return hasCourseTag && hasId;
};

const fetchCoursesFromNDK = async () => {
    try {
        if (contentIdsLoading) {
            return []; // or a loading state indication
        }
        if (contentIdsError) {
            console.error('Error fetching content IDs:', contentIdsError);
            return [];
        }
        if (!contentIds) {
            return [];
        }

        console.log('Fetching courses from NDK');
        await ndk.connect();

        const filter = { kinds: [30004], authors: [AUTHOR_PUBKEY] };
        const events = await ndk.fetchEvents(filter);

        if (events && events.size > 0) {
            const eventsArray = Array.from(events);
            console.log('eventsArray', eventsArray);
            const courses = eventsArray.filter(event => hasRequiredProperties(event));
            return courses;
        }
        return [];
    } catch (error) {
        console.error('Error fetching courses from NDK:', error);
        return [];
    }
};

const { data: courses, isLoading: coursesLoading, error: coursesError, refetch: refetchCourses } = useQuery({
    queryKey: ['courses', isClient],
    queryFn: fetchCoursesFromNDK,
    staleTime: 1000 * 60 * 30, // 30 minutes
    refetchInterval: 1000 * 60 * 30, // 30 minutes
    enabled: isClient,
});

return { courses, coursesLoading, coursesError, refetchCourses };

} ``` By incorporating these changes, you should be able to prevent errors related to contentIds being undefined and ensure a smoother data-fetching process.

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.

Bitcoin 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.

To prevent the contentIds from being undefined and causing an error, you can add handling to check if contentIds is defined before using it. Additionally, ensure contentIds has been fetched and is not in the loading state before proceeding with the fetchResourcesFromNDK function. Here is the updated useResourcesQuery with the necessary error handling

```js import { useState, useEffect } from 'react'; import { useQuery } from '@tanstack/react-query'; import { useNDKContext } from '@/context/NDKContext'; import { useContentIdsQuery } from '@/hooks/apiQueries/useContentIdsQuery';

export function useResourcesQuery() { const [isClient, setIsClient] = useState(false);

const { contentIds, contentIdsLoading, contentIdsError, refetchContentIds } = useContentIdsQuery();
const ndk = useNDKContext();

useEffect(() => {
    setIsClient(true);
}, []);

useEffect(() => {
    refetchContentIds();
}, [refetchContentIds]);

const hasRequiredProperties = (event) => {
    if (!contentIds) {
        return false;
    }
    const hasPlebDevs = event.tags.some(([tag, value]) => tag === "t" && value === "plebdevs");
    const hasWorkshop = event.tags.some(([tag, value]) => tag === "t" && value === "resource");
    const hasId = contentIds.includes(event.id);
    return hasPlebDevs && hasWorkshop && hasId;
};

const fetchResourcesFromNDK = async () => {
    try {
        if (contentIdsLoading) {
            return []; // or a loading state indication
        }
        if (contentIdsError) {
            console.error('Error fetching content IDs:', contentIdsError);
            return [];
        }
        if (!contentIds) {
            return [];
        }

        console.log('Fetching workshops from NDK');
        await ndk.connect();

        const filter = { kinds: [30023, 30402], authors: [AUTHOR_PUBKEY] };
        const events = await ndk.fetchEvents(filter);

        if (events && events.size > 0) {
            const eventsArray = Array.from(events);
            console.log('eventsArray', eventsArray);
            const resources = eventsArray.filter(event => hasRequiredProperties(event));

It wasn’t so long ago that the mainstream conversation around population was exclusively focused on the dangers of overpopulation. The fatal flaws in the Malthusian theory had yet to be disproven clearly and obviously by observable demographic trends. That’s been gradually changing, and while it’s hardly a mainstream consensus, concerns about falling birthrates and the risk of population collapse have taken over the population conversion on the political right, and sometimes beyond.

There’s no questioning the data at this point. Fertility rates over most of the world have been in precipitous decline, and if the current trajectory continues, global population will peak very soon and fall rather dramatically. And even the falling population itself is much less of a threat than the aging population that will inevitably precede it. Having a large cohort of older and retired people and a small cohort of young workers is an existential threat to the modern welfare state, and to the entire credit-based fiat monetary system that supports it. But that’s a subject for another day.

There are a multitude of different theories that attempt to explain why this is happening. I’ll name some of the most common ones:

• Increased education and employment opportunities for women

• Urbanization

• Economic factors

• Access to contraception

• Changing social and cultural norms

• Delayed marriage

• Improvements in infant mortality rates

• Government policies

• Environmental concerns

• Pornography

• Feminism

• Endocrine disrupting chemicals

• Dating apps

Most rational thinkers agree there must be multiple factors playing a role. But the fact that the problem is so wide-spread, and populations that seem to be resisting the trend are so rare, shows that the strongest underlying factors are cross-culturally powerful and not easily resisted or reversed with marginal cultural differences and standard public policy efforts.

While populations that resist the trend are rare, they are not quite non-existent. A few groups stand out for their persistently high fertility rates. On a geographic basis, sub-Saharan Africa is the only major region still maintaining above-replacement fertility rates. For various reasons, I don’t think Africa is the most useful place to look for answers on what’s causing the decline elsewhere or how it could be reversed. One reason is that Africa seems to be following the global pattern, just with a lag. In another few decades the data may look very different, just like it does for South America today compared to 20 years ago.

In my opinion, a more useful place to look for data is in smaller population sub-groups within a geographic area that have fertility rates significantly higher than the general population levels. Rural populations in general have higher fertility rates than urban populations, but the difference isn’t really enough to consider it significant. The groups that fit this category well seem to be exclusively religious. These include certain Christian denominations in the traditional Anabaptist category including the Amish, Mennonites, and Hutterites, Muslims in some areas, and Jews, particularly the most orthodox sects. Mormons recently fell out of the high-fertility religious group category, which would also make for some interesting research.

It would be fascinating to compare these groups and see what they have in common outside just being religious in nature. I don’t have the knowledge to make that comparison. Instead, I’m going to focus on the group that’s often referenced and analyzed by people without much personal knowledge, the Amish.

I have read numerous articles and comments that reference the Amish to support this or that theory on the cause of falling fertility. One thing I notice is an obvious lack of understanding of the Amish culture, which leads to faulty arguments that don’t reflect reality. This isn’t surprising, given the insular and poorly-understood nature of the culture, the plethora of ridiculously incorrect “Amish” reality TV shows and pop culture myths, and the fact that the number of people with firsthand knowledge of Amish culture from an insider perspective who also write about demographic trends on any public platform is probably zero.

Well, was zero. I’m about to make that one.

My Qualifications

Since I’m claiming to have this knowledge, it’s only fair to give a little background as to how I got it. I choose to stay anonymous on the internet, and given that this is personal information that could make it significantly easier to dox me, I’ll be deliberately vague.

My parents were both born in Amish families. They didn’t stay, opting to leave the Amish church and culture before getting married and starting their family. My grandparents were all Amish, and all my cousins and most of my extended family remain Amish to this day. My parents didn’t move out of the Amish community, staying in the area and joining a conservative Mennonite church that was about the closest thing to being Amish without actually being Amish. The Mennonite community has a generally good relationship with and a lot of respect for the Amish community, given their deep similarities and shared history and cultural background.

I grew up interacting regularly with Amish relatives, neighbors and community members, speaking the Pennsylvania Dutch my parents taught us and used exclusively at home. I’m very certain that a real deep understanding of Amish culture is almost impossible without speaking their language, just like many other cultures around the world. The Amish speak English as their second language, but there are aspects of their culture that aren’t spoken about in English.

This lifelong proximity to and interaction with the Amish community has, I believe, given me some unique insights into the factors supporting their high fertility rates that no amount of academic research will ever uncover.

Who are the Amish?

First, some basics.

The Amish are a traditionalist Christian denomination. The way to understand the Amish is as a religious denomination first, and a culture second. Getting the two mixed up makes it impossible to understand why the Amish live the way they do.

Sure, their unique lifestyles makes them noteworthy as a group. But that lifestyle is based on and maintained by their religious beliefs and convictions.

Fundamentally, the Amish attempt to live out the Gospel as Jesus taught in the Sermon on the Mount. They believe their church has done so historically, and that the best way to make sure they keep doing so in the future is to view any changes to their traditional lifestyle with extreme skepticism and resistance.

The two primary doctrines that separate them from the mainstream Protestant Reformation, which is their group’s origin, are the doctrines of nonconformity and nonresistance. They apply the doctrine of nonconformity, the command to “be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God” in both a spiritual and a practical sense. They believe that Christians are to be radically different from non-Christians, both in their beliefs and attitudes, and in their lifestyle and appearance. And they apply the command to “resist not evil”, nonresistance, to mean that it’s a sin to use physical force or violence against another person for any reason whatsoever. They don’t make any exception for military service of any type, which they object to as a matter of conscience, or for self-defense, which they refuse to engage in even if it means death for themselves or their family.

The Amish do not practice infant baptism. Their young people must choose to be baptized and formally become members of the church, usually in their late teens or early twenties. As part of the baptism ceremony, they make a vow to remain faithful to God and the church until death. The Amish, as a church, interpret this vow to mean that the new church member will remain a member of the Amish church for life. Leaving the Amish church after making this vow and being baptized is viewed as breaking the vow, and is the justification for their practice of shunning, or the ban. Those who do so are cut off from contact with the community in various ways. Typically they won’t eat a meal with a shunned person, ride in a car a shunned person is driving, or do business with a shunned person. That includes immediate family. Failure to enforce this shunning against someone, even your own child, can result in running afoul of the church leadership and also being excommunicated and shunned.

This punishment, however, only applies to people who leave the church after baptism. Those young people who choose not to be baptized and leave the church instead are free to be treated just like any other non-Amish person, although their family essentially disown them and treat them like a shunned person anyway, if they’re especially strict and upset about the betrayal of Amish values.

Most Amish people don’t believe that the Amish are the only true church, or that only Amish people are true Christians. Most are accepting of other conservative Anabaptist denominations, and respect their values and practices as a different but valid way to be Christian. Church teaching strongly suggests that those who fall under the ban are living in sin and won’t make it to heaven. Most individuals, though, probably wouldn’t agree with that in every case if they were free to give their true opinion on the issue.

The Amish maintain a fertility rate of around 6 to 7 children per woman. Some recent research suggests this may be starting to fall somewhat, but the data isn’t extensive enough to make a solid judgement yet.

There are a wide variety of different “flavors” of Amish in different areas of the US, a fact they’re very aware of. The data strongly indicates that the most conservative and technologically primitive communities have slightly higher fertility rates and significantly higher retention rates of young people.

Why do the Amish Maintain High Fertility Rates?

Okay, enough background. Time to dive into the reasons I believe the Amish maintain their historically high fertility rate despite living in a developed, modern economy surrounded by people with dramatically sub-replacement fertility rates.

I thought long and hard about the best way to approach this. Going through a list of factors topically seemed like the obvious one. But the more I thought it through, the less I liked it. For one, how do you arrange the factors? Order of importance? How do you decide that? Also, the factors are so inter-related that they’ll be very tough to separate and understand individually. Finally, it seems dry and boring. Nobody needs that.

So I’m going to try something different. I’m going to approach it from a narrative angle. I’ll try to describe the life of a typical Amish person, from birth to death, in a chronological way. That’s the best approach to present it in a way that makes the culture relatable, while also tying the different factors together logically.

I’ll describe the experience for both men and women as best I can, and try to present the various factors encouraging high fertility as I see them at the appropriate part of the story.

This will likely be an article that gets revised later to address any questions that come up, so don’t consider it the final word on the subject.

Alright, time to get started.

Subscribed

First off, this might seem obvious, but the typical Amish baby is born into a large family. On average, they’ll have 5 or 6 siblings, and more is not at all uncommon. Families of 10 won’t raise an eyebrow, and 12-16 children aren’t unheard of, especially in the past when mortality was higher and second marriages were more common among younger widowers who went on to have children with their second wife. Humans are social creatures, and the environment and people we grow up surrounded by have a strong influence on our frame of reference. Studies have shown that women are very unlikely to have more children than their mother had. The number of siblings in your family, and in families you observe and interact with, doesn’t determine the number of children you will have, but it does strongly influence the number of children you feel is a “normal” amount. That makes it a kind of ratchet effect, where it’s very unlikely that a generation raised in homes with one or two children will go on to have larger families of their own collectively.

This cultural norm of large families establishes a kind of inertia that normalizes high fertility right from birth. Amish children grow up surrounded by siblings, observing, and as they get older, helping with the care and maintenance of a large family. All their relatives, cousins and extended family are also likely to belong to large families. The average Amish child grows up with dozens of first cousins, and sometimes hundreds of more distant cousins, many of whom they likely know well and socialize with regularly. This experience establishes a mental framework where a large family is assumed to be the default. And there is no stronger human tendency than the urge to fit in with the people around you.

Amish children grow up with strong gender norms taught from a very young age. The Amish culture follows strict and conservative gender roles. Boys and men do male things, girls and women do female things, and there is little effort or desire to create any overlapping space.

Boys grow up doing traditionally masculine things. They play outside, do chores on the farm, help their dad with his work, probably get a BB gun before age 10, go hunting and fishing, play sports, and generally prepare for a lifetime of physical labor and providing for a wife and family.

Girls grow up doing traditionally feminine things. They help care for younger siblings, help with housework, play with dolls, learn to cook and preserve food, learn to sew, and generally prepare for a lifetime of caring for and raising children and maintaining a large household.

It’s a common misconception that the Amish are mostly farmers who live off the land, subsistence style. That’s not at all accurate. While there are still Amish who make their living farming, at least in some areas, that has become the exception. The large scale of modern agriculture means it takes a lot of acres and a lot of machinery to run a profitable commercial farming operation. The Amish reject the use of most modern agricultural machinery, which makes them uncompetitive in commercial agriculture outside more niche markets like dairy, produce, or greenhouses. And the fact that they live in small geographic communities with large families means they quickly buy up all available farmland in an area until they price themselves out of the market. Prime farmland in heavy Amish farming communities like Lancaster, Pennsylvania routinely sells for over $25,000 per acre, which is more than a commercial crop farming operation might bring in over a lifetime.

So the Amish have moved away from a primarily agriculture based economy to various other occupations. In some areas they work in RV factories. Most work in trades, primarily construction. Many are masons, carpenters, cabinet builders, mechanics, welders, etc.

But they reject the ownership of cars, so they still use their characteristic horses and buggies for transportation. In reality, they use cars for most of their transportation needs. But they don’t own cars or have driver’s licenses, so they rely on “Amish taxi drivers” to chauffer them around. The men hire a driver to take them to and from work, if they work in construction or some other job outside the home. The women hire a driver take them to town for their shopping or for other errands. The exception is church. They’re still required to drive to church in a horse and buggy, so every family must keep a horse for that reason, as a bare minimum. In many cases that’s the only time they ever use a horse and buggy, and if it weren’t for that requirement they wouldn’t own one at all.

But that requirement means every Amish family must own enough land to keep a horse, which takes a few acres and a small barn at minimum. This forces them to live in rural areas and raise their families in a somewhat agricultural environment, even if their occupation wouldn’t require that at all. So there are always chores for the children, animals to care for, and space to play outside with their siblings.

Amish children grow up with very limited exposure to mainstream cultural pressures. Their mothers inevitably raise them at home until they start school. They don’t have TV or cell phones, so they aren’t exposed to any mainstream culture on a daily basis.

The Amish have their own schools, typically small one room schools within walking distance of all the families who attend. The teachers are often young single people, always Amish. They primarily teach basic academics: reading, writing, arithmetic, geography, history, etc. While the Amish speak both English and Pennsylvania Dutch, many Amish children are first exposed to English on a daily basis when they start school. School is taught in English, although there is limited teaching of the High German the Amish use in their church services.

Amish children attend school until 8th grade. The schools run the minimum number of days required by the state, usually 160. There is no higher education beyond grade 8. No Amish attend college.

Amish children are taught from little up that they are not like other people. The differences between their culture and mainstream culture are emphasized, and Amish culture is praised as the ideal, at a religious level. They're taught that the way to do what’s right is to do what the church asks, and those who don’t do what the church asks are in the wrong.

The Amish rate and describe everyone on a scale from “high” to “low”. A person who isn’t Amish, who isn’t a Christian, is a “high” person, or an “English” person. To go from being Amish to being “English” is the worst, most damning, failure imaginable. The Amish are “low” people. The more strict and traditional an Amish sect, the “lower” they are. Being “low” is seen as a virtue. Other conservative Christian denominations, particularly other Anabaptist groups, are also considered “low” people and generally viewed favorably, but they aren’t as “low” as the Amish.

Amish boys grow up expecting to start work full time at age 14, and to work at some type of trade or physical labor. There are no white-collar career tracks, essentially. Entrepreneurship is encouraged, and many young Amish men start their own construction crew or home business in their 20s or 30s after a few years of experience working for someone else. Often Amish boys start off working for and with their dad, in whatever trade or business he operates. But if they’re not interested in that particular occupation, they’re free to find another. Amish businesses and tradesmen are always willing to hire young Amish boys and train them in a craft. A good work ethic is considered a virtue, and Amish are known for their skilled craftsmanship and willingness to work harder than the competition. These traits are taught and encouraged from little on up.

Amish men as a whole do very well financially. For one, they start working and developing skills and work ethic a decade earlier than the typical college graduate. The trades pay well, and of course anyone could take advantage of that, but the mainstream narrative discourages men from pursuing a trade career by labeling it low status and keeping them in education until their prime years to gain a work ethic are past. It’s not uncommon for young Amish men just out of 8th grade to land a job on a carpentry crew for $25-30 an hour. With bonuses, some of them are bringing in $90k/year before age 20. Another advantage young Amish men have is lower expenses. They can certainly find places to spend their money, typically hobbies like hunting and fishing, but things like expensive designer clothes and accessories or overpriced car payments aren’t really an option. They also benefit from the Amish exemption to Social Security taxes. The Amish don’t pay into or collect Social Security. More on that later, but it helps immensely to keep more of your paycheck in your early prime working years.

Amish girls grow up expecting to get married at a young age and raise a large family as a traditional housewife. Amish girls aren’t encouraged to have a “career”, and the idea would be silly to them. They are expected to work, but the work is either helping their mom with the household, working on the family farm or business, or doing something like teaching school or working at an Amish farmer’s market to pass the time between leaving school and marriage. It’s never viewed as a permanent occupation, because marriage and motherhood is the default aspirational lifestyle. A common job for young Amish girls is working as a “maid” to help a new mother with housework at the end of pregnancy and for the first few months after childbirth. All new mothers can get this type of help if they want, and it will usually be a younger sister, cousin, or niece of appropriate age. Otherwise the community will find a suitable girl who’s available for the job. A “maid” will sometimes travel to a different Amish community for this reason, given how large extended families are and how frequently Amish families move across the country to a different community. This is often an opportunity for them to attract the attention of a young man outside their local community, and is one of the only ways for a long-distance relationship and marriage to begin.

Amish young people are expected to live with their parents until marriage, with very few exceptions. They’re also typically expected to work for their dad in the family business for no pay, and to give any earnings they make at a day job outside the home to their parents. This is typically expected until age 21, or until they get married, whichever comes first. More recently, with the rising cost of land and housing, it’s becoming more common to make age 18 the cutoff. And when a young couple is engaged, the parents typically allow them to start saving their income for their future household. This practice helps parents offset some of the expenses of raising such large families, along with the fact that no money is spent on higher education. It also provides one strong incentive to marry as early as possible.

Amish culture revolves around family and the community. Extended families are large, and people are expected to know and interact with their family. Conversation with a stranger at a social event invariably starts by asking their name, then asking who their parents, grandparents, and other relatives are until some distant family connection or a mutual acquaintance is found. Since the Amish community has a small pool of family names, and tends to heavily favor certain Biblical first names, enough people end up with the same name to make things really confusing. People are often identified by two or three generations of their family, for example “Sam Yoder’s John’s Amos” for an Amos Yoder who’s father was John Yoder and grandfather Sam Yoder.

Social activities are either family events or church events, or both. Weddings and funerals are the main social functions other than church services, and people are expected to attend as many as possible among their family and extended family, regardless of the distance. Given the large family sizes, most Amish have dozens of first cousins and many more distant cousins. Weddings and funerals can be almost weekly events. These are church events as well, so much of the local Amish community will usually attend. It will be an all day event, with the women and girls preparing a lunch and dinner for everyone. After the meal, the women and girls will wash the dishes and clean up, while the men sit around and talk. No cell phones, remember. Talking is the main form of social interaction. Topics typically include work, family news, hunting and fishing stories (Amish men hunt and fish with the same enthusiasm typical American men watch sports), horses, and interesting or funny stories about family and friends. Those with a knack for entertaining oratory are well respected and appreciated in the Amish community.

Of course the women do their fair share of talking as well, in the kitchen while cleaning up after the meal, and later in the living room where they join the men after the domestic work is done. The main topics of conversation always revolve around family, immediate and extended. News travels through the Amish community faster than any social media platform, because nothing builds Amish female status more than being the first to call with the news that great uncle so-and-so was injured in a farming accident or nephew so-and-so has a new baby, along with all the pertinent details about the name, size, and health of the baby and how the mother is doing and how many grandchildren that makes in total for the lucky grandparents.

While the adults are talking, the children are free to play either inside or preferably outside. Trampolines, climbing trees, playing in the hayloft, tag, volleyball, and softball are favorite activities at various ages. The younger boys and girls typically play together, but as they get older the girls spend more time visiting while the boys prefer more structured sports. Softball is a game for boys, but volleyball is popular with mixed teams of boys and girls at any age.

Visiting relatives or other community families is also a popular social activity, especially on “in-between Sunday”. The Amish have church every other week, and the week without church is often an opportunity to visit another family. Invitations are not expected or required, and anyone stopping by will be expected to stay for dinner and into the evening. At these type of events, the older children are often expected to sit and visit with the adults. Sitting still and being quiet are mandatory skills, since church services are 2 hours or longer and held in barns or sheds without air conditioning filled with backless wooden benches. Self-discipline is not an optional virtue, because the alternative is physical discipline.

As Amish young people enter their mid teen years, they go from childhood to youth. At a certain age, usually around 15 or 16, they officially become youth and enter the stage everyone is familiar with, “rumspringa”. That’s a Pennsylvania Dutch word that translates to “running around”. The Amish use it more as a verb, but pop culture has adopted it as a noun based on some wildly inaccurate reality TV shows and depictions.

The reality is, rumspringa varies widely from community to community, mostly based on what the parents and church leaders tolerate. Remember that Amish church membership is a fully voluntary decision, and Amish young people are free to join or not, as they decide. Late teens is the typical age for that decision. In the meantime, they are free to make their own decisions, subject to their parents’ rules. Breaking the rules can mean that at some point, they won’t be welcome to live in their parents’ household any more. That’s a fairly strong deterrent to the most extreme infractions.

At this stage, young Amish men will be buying their own horse and buggy, and both boys and girls will be permitted to attend the Sunday night “singing”. This is a social activity held at someone's house on Sunday evening, involving all the youth in the community coming together for dinner, playing volleyball, and singing German hymns together. The purpose is to provide a somewhat controlled social environment for young men and women to interact and hopefully meet their future spouse. Dating couples can attend together, and dates are permitted after the formal activities, with the young men often driving their date home late at night before finally heading home themselves.

Depending on the tolerance of the community, the informal activities can be a bit more permissive than singing hymns and playing volleyball. Often the buggies will become a typical teenage party scene, with alcohol, smoking, a radio, illicit smartphones and DVD players, and some less-than-reserved interaction between boys and girls. The punishment for getting caught can be severe, but in many cases the adults tend to turn a blind eye to what’s happening, and let the young people do as they please.

A lot more could be said about the dynamics of this cultural practice, but specifics vary so much between communities that I don’t think there’s much value in doing so. The point I think is relevant to this discussion is the question of sex.

There’s no reason to go off into the weeds on how much, if any, sex occurs. Premarital sex is absolutely forbidden. Does it happen anyway? Humans being human, certainly. How much? Probably very little in most cases. Getting pregnant, or getting someone pregnant, is the one transgression with inevitable life-changing consequences. The “shotgun wedding” is alive and well among the Amish, and getting a girl pregnant means marrying her or being expelled from the Amish community permanently, no exceptions. Besides that, getting pregnant outside of marriage is the most disgraceful and shameful thing a girl could do. It happens very very rarely, put it that way.

So casual sex within the community is basically off the table. What about casual sex with “English” people? This is where the Amish cultural practices play a big role. The Amish dress very distinctly. They can’t go anywhere in their traditional clothes without being instantly recognized. They also don’t drive cars, so going somewhere means getting a ride with someone. And their parents will usually keep an eye on their plans and whereabouts. So let’s imagine how an Amish teenager might go about finding a casual sexual encounter.

First off, getting ahold of a cell phone would be essential. They need some way to communicate with the outside world, and coordinate with their “partner in crime.” A lot of Amish teenagers do this, often with the help of slightly older people who have left the Amish, but keep ties with the community, maybe an older sibling or cousin. These are often the same people who buy alcohol for Amish teens.

Then, they need to get some non-Amish clothes. Remember, every trip away from home will take a willing driver, a plausible excuse in a community where everyone knows everyone, and the guarantee of being immediately recognized if seen in public. And the Amish parents know who the “bad kids” are, the ones who left but are willing to help their younger relatives and friends break the rules. Getting caught hanging around with them will probably mean a lot less trust and a lot less freedom in the future.

For the girls, a change of “English” clothes and a new hairstyle will let them blend in quite well. Of course, they can’t be caught leaving or coming home in those clothes, or have the clothes found at home. Lots of logistical hurdles everywhere. For the boys, they have a very distinctive haircut. A new change of clothes won’t fix that. There’s really no way for them to hide the fact that they’re Amish, even if the accent and the lack of a driver’s license don’t give them away.

Assuming they manage all that, and sneak away from home undetected, how will they find someone to hook up with? They’re very insulated from popular culture, and probably not at all comfortable in typical social situations. For the girls, there’s the added risk that an accidental pregnancy, or even just getting caught, would ruin their reputation and any chance of marriage and a family in the Amish community. So they’re unlikely to even try, unless they’re already fully intending to leave the Amish for good. That only really happens if they have a guy ready to marry them outside the Amish community, for reasons I’ll get into more later. Briefly, the Amish culture and schooling leaves women poorly prepared to support themselves outside that culture.

For the boys, there’s the typical difficulty men face in finding casual sexual partners. Multiply that by the difficulty of not having a car or driver’s license, not being experienced in mainstream social norms, plus that obvious and undisguisable Amish haircut. And all that ignores the lifelong teaching that casual sex is sinful and wrong, and those who engage in it are going against the teachings of God and the church. The entire culture is specifically designed to discourage casual sex as strongly as possible, and it does an excellent job at that.

Why does that matter? Well, humans are all very much the same, with the same desires and instincts. And sex is one of the strongest of those desires. The Amish are certainly no different.

So the Amish religious practice and culture offers a very simple choice. You can choose sex outside of marriage, which will be difficult or impossible, occasional at best, and if you get caught will mean expulsion from the community your life is rooted in, and even if you don’t get caught will mean you’re committing a mortal sin that will keep you out of heaven if you don’t repent and change. Or, you can get married and have all the sex you want, and be respected and rewarded for it.

That’s really all it takes to sell the idea of marriage to most men.

When a couple does decide to get engaged, of course with permission from the girl’s father, the wedding happens within a reasonably short time, in acknowledgement of the temptation young people face in that situation.

So let’s take a little closer look at the gender differences between the choice to stay single or to marry. It’s helpful to lay out the different life paths available, and how they play out over time.

There are very few Amish who remain single throughout their life, and almost all of them are women. So let’s look at it through a man’s perspective first. What kind of life can a single Amish man expect?

First off, a lifetime of celibacy. There’s hardly any need to go further, that’s a deal breaker for most men. If they choose to stay single for some reason, most will leave the Amish completely rather than accept those terms.

So maybe it’s more useful to look at incentives for early marriage, which is the norm. I’m a strong believer that incentives create outcomes, so I’ll be taking a hard look at incentives throughout this article.

Young people are expected to live with their parents until marriage, in most cases. Remember, no going off to college either. So from age 14 on, they’re stuck living with Mom and Dad, working full time, and not even keeping their own income. That gets old fast. Getting married, moving out, and starting a family looks better every day. Besides that, Amish women do a lot to improve the lives of their men. The Amish are well known for their delicious food. Well, that’s because the Amish women cook and bake. As a single guy, moving out of Mom’s house means not getting delicious home-cooked food every day. And they don’t have an iPhone to order DoorDash either, so it’s pizza delivery, hiring a driver to go to a restaurant, or whatever you can cook yourself. And Amish boys don’t grow up learning how to cook, that’s women’s work. Same with making clothes. Amish mothers and wives sew clothes for their families, since they’re forbidden to wear commercially available clothes in general. So a single guy is dependent on his mom for new clothes as well. Same with washing clothes. Most Amish have fairly modern clothes washing machines, although they don’t use dryers. But washing and folding clothes isn’t a job most boys grow up doing, so they’re pretty lost if they have to try it.

All in all, there aren’t a lot of upsides to staying single longer than absolutely necessary. There are plenty of benefits to marriage, though. For one, marriage is seen as a necessary step to full maturity as a man. It’s even expressed as a visible marker. Single young men typically stay clean-shaven. Once they get married, shaving is completely forbidden, and they are required to grow out a full beard. So the difference between married and single men is obvious at first glance, and is acknowledged as a marker of full maturity.

Then of course there’s the sexual access. No explanation needed.

Then there are all the benefits of an improved lifestyle a stay-at-home wife provides. That includes cooking, cleaning, washing clothes, caring for a garden, preserving food, helping with farm work or chores, and helping with his business. Many Amish wives are very involved in their husband’s career or business, whether that’s managing the bookkeeping, working in the greenhouses, or helping with daily chores on the farm. While most Amish communities use quite modern household appliances, powered with batteries, kerosene, or air pressure, the work of maintaining a household is still much more involved than for the typical American household. Especially when it comes to sewing, which very few American women do at all, but which took a large percentage of women’s time only a few generations ago. Among the Amish it still does.

I’m only focusing on the incentives for marriage right now, because that’s the first step. Of course, most married couples today don’t have 5-8 children, so there’s more to the story. But universal marriage, particularly early marriage, is an essential part of the puzzle.

Shifting focus to the women, here the picture is even more clear. Almost all lifelong single Amish people are women, and that’s not by choice. The Amish still maintain the “old maid” category that used to be part of mainstream culture. Single Amish women are almost invariably single because no man offered to marry them. Here’s why.

If single life is unappealing for Amish men, it’s positively bleak for women. Marriage and family life is the aspirational goal they’re taught from little up. And for good reason.

With their eighth-grade education, and without a driver’s license and car, their income earning potential is very limited. Most young women who aren’t busy on the farm or with the family business work as schoolteachers, housecleaners, babysitters, or cooks and servers at Amish restaurants or farmers’ markets. None of these jobs pay well. Enough to buy a few personal items, but not enough to buy a house or support even one person. And while it might be acceptable for a single Amish man to eventually buy a house and move out, at some point in his late 20s or early 30s, it’s really not acceptable at any age for an Amish old maid. Those old maids typically end up living with their parents, caring for them in old age, working the same type of jobs young girls do, and probably hoping that at some point an older widower with a family will show up and propose.

Marriage has massive lifestyle benefits for women, even more so than for men. Amish men typically do well financially, and often work in construction as well, or have friends and relatives who do. Amish houses are very nice and well constructed to say the least, and the wife gets the house she wants, the way she wants it. Being stingy with a house for your wife isn’t part of an Amish man’s mentality. Amish women are well rewarded for all their hard work keeping house, with a house they’ll be happy keeping. And of course a nice farm or at least some acreage, with space for a big garden, a barn for any animals, and space for greenhouses or whatever she needs for any home business ambitions she might have.

Along with that, Amish women have a lot of flexibility when it comes to spending money. Many Amish women handle most of the family finances. And the money her husband earns is family money, not his money. While the husband has final say in financial decisions, most Amish men don’t say no to their wives’ purchase requests often. Married Amish women have access to all the creature comforts the church allows to make their lives as pleasant as possible.

When it comes to status, the benefits are just as clear. Amish life revolves around family, and nothing is higher status than a thriving family of your own. The Amish version of posting exotic vacation pictures on Instagram is showing up to a social function with your new baby. It’s the automatic center of attention for weeks, until a newer baby show up in the community. And the default topic of conversation is always a woman’s children and their growth and development. Young girls grow up dreaming of the day they can join those conversations, and old maids are always outsiders in a certain sense, pitied by everyone else for their misfortune.

Being an old maid means being poor, low status, pitied by other women, and destined to live with your parents until they pass, with your only bitter-sweet consolation being the role of aunt to your dozens of nieces and nephews and maid to your sisters and sisters-in-law through their many pregnancies. Getting married means access to a man’s income, a nice new house just the way you want it, a farm, and an automatic status boost as a mother and eventually grandmother who always has lots to contribute to the conversation at social events.

As you can imagine, the incentives strongly favor marriage from both directions. Men benefit through improved lifestyle, status, and access to sex. Women benefit through improved lifestyle, economic opportunity, and status in the social hierarchy.

Given that the selection pool for potential partners is limited, mostly to the local Amish community, or occasionally another Amish community if there’s some interaction through family ties or social events, assortative mating is the norm. Young people can be choosy, sure. But they already know most of the people in their potential mating pool, and have probably known those people for most of their lives. They have a pretty good idea how desirable they are to potential partners, and the girls especially have to think long and hard about turning down a suitor. Men are always the initiators of a relationship, and the risk of turning down an eligible man and then never getting another offer, ending up as a dreaded old maid, is always lurking in the back of their minds.

Besides that, both men and women have multiple ways to improve their spouse’s life. Women are much more than just sexual objects. Their domestic role actually raises their husband’s standard of living significantly, in a way he can’t access as a single man. And men are all valuable to women, both for resources and for status as a wife and mother. Even a very average husband or wife is a massive lifestyle boost over remaining single.

By now it should be pretty clear why marriage is almost universal among the Amish, and marriage at what most would consider a young age (19-23) is more common than not. And I haven’t even mentioned any religious teaching, because frankly I don’t think that’s a major force on an individual level. The religious beliefs shape the social and material landscape, and that landscape provides the practical incentives that cause people to make the choices they do. The fact that an Amish interpretation of the Bible encourages marriage and children is one layer removed from the reasons individual 20-year-old Amish men and women choose to get married.

I pointed out earlier that getting married and having a high birthrate, or even getting married young and having a high birthrate, are not exactly the same thing. Plenty of married couples today have one, two, or even no children, even if they got married young enough to have ten if they chose to do so. So why are the Amish different?

There’s the too-obvious answer: they don’t allow the use of contraceptives. Occam’s razor and all, but it deserves a bit more explanation. After all, the Catholic Church doesn’t allow the use of contraceptives either, and look how well that’s working out for them. Of course the enforcement mechanism doesn’t have the teeth among Catholics that it has among the Amish, but that’s not the whole story. If they were motivated enough, there’d be a way to space the children out more, maybe end up without quite so many, without anyone knowing. That doesn’t happen, because the contraceptive ban is a dead letter when couples want to have as many children as possible, which the Amish typically do.

Again, I’ll go back to incentives. What are the incentives to have children specifically, as many as possible, and not just get married and “plan for a family one day”?

For one, status. For both men and women, a large family is a marker of high status. Parents are respected and honored for doing a good job of raising well-adjusted children.

Children are also less of a financial burden for the Amish. Their children are raised well, but not in a financially intensive way that’s become expected today. They don’t have to buy a new car or SUV to fit the family, they don’t buy every child a boatload of expensive electronic gadgets every birthday and Christmas, they don’t have to pay for frequent vacations or college tuition, and they don’t have to eat out or pay for takeout or pay for childcare or a house cleaner since the wife is handling all those domestic roles herself. And the Amish don’t practice helicopter parenting, so children are much more free to play and amuse themselves without constant supervision from their parents. They don’t have to be driven to 17 different weekly structured activities. They have a farm to play on and shelves full of books to read and some toys to play with if the weather is bad, and that’s about it. And of course as the family grows, the older siblings do a large percentage of the housework and help with the younger children.

The older teenagers that are working outside the home typically give their earnings to their parents, but this basically offsets the cost of raising them, so it isn’t really an incentive to have larger families, just the removal of a disincentive.

The strongest real incentive, other than increased status and cultural inertia, that I observe for large families is that the children are the parents’ retirement plan. The Amish don’t work at jobs that offer pensions or benefits. They are exempt from paying into, but also ineligible to receive, Social Security benefits. The Social Security exemption was granted on the basis that the Amish don’t need government payments to support them in old age, because the family and community will do that. And they do.

How does this work out in practice? First, the Amish don’t practice “retirement” the way most people think of it. They teach that work is honorable and every able-bodied man should work to support his family and to help those in need. So as long as a man is physically able to work, he’ll be employed and supporting himself and his wife. And Amish women move directly from the role of mother to the role of grandmother. It’s not at all uncommon, in fact, for a woman’s first grandchild to be born before her last child is born. So plenty of Amish children are an aunt or uncle at birth, and have a niece or nephew older than they are. Grandmothers are extremely involved in helping their daughters and daughters-in-law with childcare, so they don’t often have a big stretch of free time after their children grow up and move out. And besides that, there are still the significant household responsibilities to attend to.

As a couple gets older and perhaps less able to handle everything on their own, they often move to the home of one of their grown children. Typically not into the home directly, but into what’s called a “dody haus” (grandpa house) which might be a small detached house on the same property, or a separate wing of the larger house, like an in-law suite. Here they’re able to live independently, help care for the grandchildren next door, and still be nearby so their children and grandchildren can give any care they may need in old age. If the couple has an unmarried “old maid” daughter, she’ll typically still be living with them and will be the primary caregiver.

If someone doesn’t have children to care for them, the Amish community will find a way to care for them. Some more distant relative or maybe surviving siblings will step in to help. But the expectation and the rule is that your children and grandchildren will care for you after you’re no longer able to care for yourself. Finding yourself growing old without family is an unfortunate and unpleasant situation, regardless how much the community may try to fill that role. Just as throughout earlier stages of life, social functions and social status revolve around children and family, and anyone without them will be incomplete as a person, something of an inevitable outsider to the joys of life. The best insurance against a lonely and uncomfortable old age is a large family, among which there are certain to be sufficient resources to care for you. Many elderly Amish people die with well over a hundred grandchildren and great-grandchildren, and spend their later years constantly surrounded by children and young people who deeply appreciate and respect them. Being taught and shown that respect toward their own grandparents from a young age is a strong incentive to aspire to the same status one day.

I’m not sure exactly where this fits, but I should point out somewhere that the Amish have an absolutely zero tolerance policy toward divorce. There are no legitimate grounds for divorce whatsoever, and anyone who initiates a divorce will be excommunicated from the church and shunned. If an Amish person’s spouse initiates divorce proceedings, they won’t cooperate with those proceedings in any way. If the divorce happens through the legal system without their consent anyway, they can remain a church member in good standing only by staying celibate as long as their spouse remains alive. The only acceptable second marriage is in the case of the death of a spouse. In those cases, a quick remarriage is the rule among widows and widowers with young children, since raising a family is seen as a job for a married couple, not a single person.

It’s hard to say exactly how this stance against divorce influences marriage and fertility. But it certainly limits exposure to the idea of divorce as a “solution” to marriage difficulties, and incentivizes couples to work things out for their own life satisfaction. And it dramatically reduces the financial risks men face in the modern marriage system, where the potential to lose not only their family, but also a significant portion of their material wealth, raises strong disincentives to marriage. The physical realities of married life versus single life in a more low-tech environment probably discourage divorce, but the added threat of complete social and familial ostracization eliminate it almost entirely.

Conclusion

This article is my attempt to provide some insight into the Amish culture that might help us understand the factors causing their unusually high fertility rate. I’ve titled it as part one, because I plan to follow up with some of my personal opinions on how these insights relate to the broader society. I think a lot of the proposed causes of and solutions to the global demographic collapse are completely incorrect, and my opinion is based heavily on my observation of Amish culture. That will be the focus of part two of this article.

Feel free to comment and post questions. My biggest challenge in writing this article is the fact that I take my familiarity with Amish culture for granted to some degree, so I struggled to choose which points are relevant to understanding the culture for an outsider. I’m sure I skipped over plenty of important details that may leave readers feeling confused, so I’ll do my best to answer any questions you post, and update the article with pertinent information I missed.

According to the ECB Executive Board member, the launch of the digital euro depends on the timing of the EU regulation.

The European Central Bank (ECB) is making progress in preparing for the digital euro. According to Piero Cipollone, ECB Executive Board member and coordinator of the project, the technical phase “is proceeding quickly and on schedule,” but moving to operational implementation still requires political approval of the regulation at the European level.

Speaking at the ‘Voices on the Future’ event organized by Ansa and Asvis, Cipollone outlined a possible timeline:

“If the regulation is approved at the start of 2026 — in the best-case scenario for the European legislative process — we could see the first transactions with the digital euro by mid-2028.”

Cipollone also highlighted Europe’s current dependence on electronic payment systems managed by non-European companies:

“Today in Europe, whenever we don’t use cash, any transaction online or at the supermarket has to go through credit cards, with their fees. The payment system relies on companies that aren’t based in Europe. You can see why it would make sense to have a system fully under our control.”

For the ECB board member, the digital euro would act as a direct alternative to cash in the digital world, working like “a banknote you can spend anywhere in Europe for any purpose.”

The digital euro project is part of the ECB’s broader strategy to strengthen the independence of Europe’s financial system. According to Cipollone and the Central Bank, Europe’s digital currency would be a key step toward greater autonomy in electronic payments, reducing reliance on infrastructure and services outside the European Union.

The post ECB: digital euro by mid-2028, says Cipollone appeared first on Atlas21.

A young girl from Innis-Sark had a lover, a fine young fellow, who met his death by an accident, to her great grief and sorrow.

One evening at sunset, as she sat by the roadside crying her eyes out, a beautiful lady came by all in white, and tapped her on the cheek.

“Don’t cry, Kathleen,” she said, “your lover is safe. Just take this ring of herbs and look through it and you will see him. He is with a grand company, and wears a golden circlet on his head and a scarlet sash round his waist.”

So Kathleen took the ring of herbs and looked through it, and there indeed was her lover in the midst of a great company dancing on the hill; and he was very pale, but handsomer than ever, with the gold circlet round his head, as if they had made him a prince.

“Now,” said the lady, “here is a larger ring of herbs. Take it, and whenever you want to see your lover, pluck a leaf from it and burn it; and a great smoke will arise, and you will fall into a trance; and in the trance your lover will carry you away to the fairy rath, and there you may dance all night with him on the greensward. But say no prayer, and make no sign of the cross while the smoke is rising, or your lover will disappear for ever.”

From that time a great change came over Kathleen. She said no prayer, and cared for no priest, and never made the sign of the cross, but every night shut herself up in her room, and burned a leaf of the ring of herbs as she had been told; and when the smoke arose she fell into a deep sleep and knew no more. But in the morning she told her people that, though she seemed to be lying in her bed, she was far away with the fairies on the hill dancing with her lover. And she was very happy in her new life, and wanted no priest nor prayer nor mass any more, and all the dead were there dancing with the rest, all the people she had known; and they welcomed her and gave her wine to drink in little crystal cups, and told her she must soon come and stay with them and with her lover for evermore.

Now Kathleen’s mother was a good, honest, religious woman, and she fretted much over her daughter’s strange state, for she knew the girl had been fairy-struck. So she determined to watch; and one night when Kathleen went to her bed as usual all alone by herself in the room, for she would allow no one to be with her, the mother crept up and looked through a chink in the door, and then she saw Kathleen take the round ring of herbs from a secret place in the press and pluck a leaf from it and burn it, on which a great smoke arose and the girl fell on her bed in a deep trance.

Now the mother could no longer keep silence, for she saw there was devil’s work in it; and she fell on her knees and prayed aloud—

“O Maia, mother, send the evil spirit away from the child!”

And she rushed into the room and made the sign of the cross over the sleeping girl, when immediately Kathleen started up and screamed—

“Mother! mother! the dead are coming for me. They are here! they are here!”

And her features looked like one in a fit. Then the poor mother sent for the priest, who came at once, and threw holy water on the girl, and said prayers over her; and he took the ring of herbs that lay beside her and cursed it for evermore, and instantly it fell to powder and lay like grey ashes on the floor. After this Kathleen grew calmer, and the evil spirit seemed to have left her, but she was too weak to move or to speak, or to utter a prayer, and before the clock struck twelve that night she lay dead.

Recently 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.

Streams are the key to nostr

Loading events from a nostr relay is probably the most inconsistent way of loading data I've had to work with, and that's only loading from a single relay. the problem gets exponentially more complicated once you try to load events from multiple relays

Unlike HTTP nostr does not have a simple flow with timeouts built in. events are sent back one at a time and can fail at any point or have massive (10s) gaps between them

The key is to use streams. something that starts, emits any number of results, then maybe errors or completes. luckily it just so happens that JavaScript / TypeScript has a great observable stream library called RxJS

What is an observable

An Observable in RxJS is stream a of data that are initialized lazily, which means the stream is inactive and not running until something subscribes to it

```ts let stream = new Observable((observer) => { observer.next(1) observer.next(2) observer.next(3) observer.complete() })

// The stream method isn't run until its subscribed to stream.subscribe(v => console.log(v)) ```

This is super powerful and perfect for nostr because it means we don't need to manage the life-cycle of the stream. it will run when something subscribes to it and stop when unsubscribed.

Its helpful to think of this as "pulling" data. once we have created an observable we can request the data from it at any point in the future.

Pulling data from relays

We can use the lazy nature of observables to only start fetching events from a nostr relay when we need them

For example we can create an observable that will load kind 1 events from the damus relay and stream them back as they are returned from the relay

```typescript let req = new Observable((observer) => { // Create a new websocket connection when the observable is start let ws = new WebSocket('wss://relay.damus.io')

ws.onopen = () => { // Start a REQ ws.send(JSON.stringify(['REQ', 'test', {kinds: [1], limit: 20}])) }

ws.onmessage = (event) => { let message = JSON.parse(event.data) // Get the event from the message and pass it along to the subscribers if(message[0] === 'EVENT') observer.next(message[1]) }

// Cleanup subscription return () => { ws.send(JSON.stringify(['CLOSE', 'test'])) ws.close() } }) ```

But creating the observable wont do anything. we need to subscribe to it to get any events.

ts let sub = req.subscribe(event => { console.log('we got an event' event) })

Cool now we are pulling events from a relay. once we are done we can stop listening to it by unsubscribing from it

ts sub.unsubscribe()

This will call the cleanup method on the observable, which in turn closes the connection to the relay.

Hopefully you can see how this work, we don't have any open, connect, or disconnect methods. we simply subscribe to a stream of events and it handles all the messy logic of connecting to a relay

Composing and chaining observables

I've shown you how we can create a simple stream of events from a relay, but what if we want to pull from two relays?

Easy, lets make the previous example into a function that takes a relay URL

```ts function getNoteFromRelay(relay: string){ return new Observable((observer) => { let ws = new WebSocket(relay)

// ...rest of the observable...

}) } ```

Then we can "merge" two of these observables into a single observable using the merge method from RxJS

The merge method will create a single observable that subscribes to both upstream observables and sends all the events back. Think of it as pulling events from both relays at once

```ts import { merge } from 'rxjs'

const notes = merge( getNoteFromRelay('wss://relay.damus.io'), getNoteFromRelay('wss://nos.lol') )

// Subscribe to the observable to start getting data from it const sub = notes.subscribe(event => { console.log(event) })

// later unsubscribe setTimeout(() => { sub.unsubscribe() }, 10_000) ```

But now we have a problem, because we are pulling events from two relays we are getting duplicate events. to solve this we can use the .pipe method and the distinct operator from RxJS to modify our single observable to only return one version of each event

The .pipe method will create a chain of observables that will each subscribe to the previous one and modify the returned values in some way

The distinct operator takes a method that returns a unique identifier and filters out any duplicate values

```ts import { merge, distinct } from 'rxjs'

const notes = merge( getNoteFromRelay('wss://relay.damus.io'), getNoteFromRelay('wss://nos.lol') ).pipe( // filter out events we have seen before based on the event id distinct(event => event.id) ) ```

Now we have an observable that when subscribed to will connect to two relays and return a stream of events without duplicates...

As you can see things can start getting complicated fast. but its also very powerful because we aren't managing any life-cycle code, we just subscribe and unsubscribe from an observable

Taking it to an extreme

Hopefully at this point you can see how powerful this is, we can think of almost any data loading pattern as a series of observables that pull data from upstream observables and stream it back to the original subscriber.

Here is a quick sketch of what it could look like to load user profiles. each node is an observable that "pulls" data from its child node ending with the "connect websocket" or "load from database" nodes which do the work of making a relay connection

Conclusion

All this might seem pretty simple and straight forward, but its been a long six month of learning for me. I've had to completely rethink how data and nostr events should be handled in a client and how to avoid screwing up and shooting myself in the foot with these powerful tools.

If you want to give RxJS a try I would encourage you to checkout the nostr sdk I've been building called applesauce

Its uses RxJS for pretty much everything and has the simplest and most flexible relay connection API I've seen so far (mainly no life-cycle management)

Decentralization refers to control/power, and relates to censorship resistance. That is it, it is not more complicated then that. Resilience is a function of redundancy; a centralized censored system can have a redundant set-up and therefor be resilient.

Take Bitcoin; the blockchain is a central database, it is resilient because it has many redundant copies among a lot of different nodes. The message (txs and blocks) propagation is decentralized due to existence of a p2p network among these nodes, making the data distribution censorship resistant (hello op_return debate). But onchain transactions themselves are NOT p2p, they require a middlemen (a miner) because it is a central database, as opposed to something like lightning which is p2p. Peer to Peer says something about relative architectural hierarchical position/relation. P2P provides censorship resistance because it entails equal power relations, provided becoming a peer is permissionless. What makes onchain transactions censorship resistant is that mining is permissionless, and involves this open power struggle/game where competition results in a power distribution among players, meaning (hopefully) decentralization. The fact users rely on these middlemen is mitigated by this decentralization on the one hand, and temper-proofing via cryptographic signatures on the other, resulting in what we call trustlessness (or trust minimization for the autists in the room); we only rely on a miner to perform a job (including your tx into a block), but we don’t trust the miner to perform the job correctly, this we can verify ourselves.

This leads us to Nostr, because that last part is exactly what Nostr does as well. It uses cryptography to get tamper-proof messaging, which then allows you to use middle-men in a trust minimized way. The result is decentralization because in general terms, any middle man is as good as any other (same as with miners), and becoming such a middleman is permissionless(somewhat, mostly); which in turn leads to censorship resistance. It also allows for resilience because you are free to make things as redundant as you'd like.

Ergo, the crux is putting the cryptography central, making it the starting point of the system; decentralization then becomes an option due to trust minimization. The difference between Bitcoin an Nostr, is that Bitcoin maintains a global state/central ledger and needs this PoW/Nakamoto consensus fanfare; Nostr rests itself with local perspectives on 'the network'.

The problem with the Fediverse, is that it does not provide trust minimization in relation to the middlemen. Sure, there are a lot different servers, but you rely on a particular one (and the idea you could switch never really seemed to have materialized in a meaningful way). It also fails in permisionlessness because you rely on the association between servers, i.e. federation, to have meaningful access to the rest of the network. In other words, it is more a requirement of association than freedom of association; you have the freedom to be excommunicated.

The problem with ATproto is that is basically does not solve this dynamic; it only complicates it by pulling apart the components; identity and data, distribution and perspective are now separated, and supposedly you don’t rely on any particular one of these sub-component providers in the stack; but you do rely on all these different sub-component providers in the stack to play nice with each other. And this ‘playing nice’ is just the same old ‘requirement of association’ and ‘freedom of excommunication’ that looms at the horizon.

Yes, splitting up the responsibilities of identity, hosting and indexing is what is required to safe us from the platform hellscape which at this stage takes care of all three. But as it turns out, it was not a matter cutting those up into various (on paper) interchangeable middlemen. All that is required is putting cryptographic keys in the hands of the user; the tamperproofing takes care of the rest, simply by trust minimizing the middlemen we use. All the sudden it does not matter which middlemen we use, and no one is required to play nice; we lost the requirement of association, and gained freedom of association, which was the purpose of censorship resistance and therefor decentralization, to begin with.
