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.

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.

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.

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.

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. 🫡

In much of the world, it is incredibly difficult to access U.S. dollars. Local currencies are often poorly managed and riddled with corruption. Billions of people demand a more reliable alternative. While the dollar has its own issues of corruption and mismanagement, it is widely regarded as superior to the fiat currencies it competes with globally. As a result, Tether has found massive success providing low cost, low friction access to dollars. Tether claims 400 million total users, is on track to add 200 million more this year, processes 8.1 million transactions daily, and facilitates $29 billion in daily transfers. Furthermore, their estimates suggest nearly 40% of users rely on it as a savings tool rather than just a transactional currency.

Tether’s rise has made the company a financial juggernaut. Last year alone, Tether raked in over $13 billion in profit, with a lean team of less than 100 employees. Their business model is elegantly simple: hold U.S. Treasuries and collect the interest. With over $113 billion in Treasuries, Tether has turned a straightforward concept into a profit machine.

Tether’s success has resulted in many competitors eager to claim a piece of the pie. This has triggered a massive venture capital grift cycle in USD tokens, with countless projects vying to dethrone Tether. Due to Tether’s entrenched network effect, these challengers face an uphill battle with little realistic chance of success. Most educated participants in the space likely recognize this reality but seem content to perpetuate the grift, hoping to cash out by dumping their equity positions on unsuspecting buyers before they realize the reality of the situation.

Historically, Tether’s greatest vulnerability has been U.S. government intervention. For over a decade, the company operated offshore with few allies in the U.S. establishment, making it a major target for regulatory action. That dynamic has shifted recently and Tether has seized the opportunity. By actively courting U.S. government support, Tether has fortified their position. This strategic move will likely cement their status as the dominant USD token for years to come.

While undeniably a great tool for the millions of users that rely on it, Tether is not without flaws. As a centralized, trusted third party, it holds the power to freeze or seize funds at its discretion. Corporate mismanagement or deliberate malpractice could also lead to massive losses at scale. In their goal of mitigating regulatory risk, Tether has deepened ties with law enforcement, mirroring some of the concerns of potential central bank digital currencies. In practice, Tether operates as a corporate CBDC alternative, collaborating with authorities to surveil and seize funds. The company proudly touts partnerships with leading surveillance firms and its own data reveals cooperation in over 1,000 law enforcement cases, with more than $2.5 billion in funds frozen.

---

The global demand for Tether is undeniable and the company’s profitability reflects its unrivaled success. Tether is owned and operated by bitcoiners and will likely continue to push forward strategic goals that help the movement as a whole. Recent efforts to mitigate the threat of U.S. government enforcement will likely solidify their network effect and stifle meaningful adoption of rival USD tokens or CBDCs. Yet, for all their achievements, Tether is simply a worse form of money than bitcoin. Tether requires trust in a centralized entity, while bitcoin can be saved or spent without permission. Furthermore, Tether is tied to the value of the US Dollar which is designed to lose purchasing power over time, while bitcoin, as a truly scarce asset, is designed to increase in purchasing power with adoption. As people awaken to the risks of Tether’s control, and the benefits bitcoin provides, bitcoin adoption will likely surpass it.

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.

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.

NIPs

Allow multi-user AUTH #1881 vitorpamplona is proposing a PR that reuses one connection for everyone by accepting multi-user logins on the relay side. Additionally, this PR standardizes how relays should handle multiple AUTH messages from the client, instead of leaving it as undefined behavior. Currently, most relays override the previous AUTH, which means developers can rotate the authenticated user within the same connection. Some relays only accept the first AUTH and ignore the rest. A few newer relays already support multi-user logins as described in this PR, which he believes is the correct way to implement NIP-42 AUTH. The purpose of this PR is to formalize that behavior.

Adds optional nip60.signSecret() and kind 10019 filter tag #1890 robwoodgate is proposing a PR that clarifies and improves Nostr <---> Cashu interoperability as follows:Adds an optional signer signature for NUT-10 well-known secrets to NIP-60, NIP-07 and NIP-46；Clarifies use of Nostr <---> Cashu public keys in NIP-61；Adds an optional reverse lookup filter tag to NIP-61 kind 10019 events.

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

Gen Z (those born between 1997 and 2012) are not rushing to stack sats, and Oliver Porter, Founder & CEO of Jippi, understands the challenge better than most. His strategy revolves around adapting Bitcoin education to fit seamlessly into the digital lives of young adults.

“We need to meet them where they are,” Oliver explains. “90% of Gen Z plays games. 70% expect to earn rewards.”

So, what will effectively introduce them to Bitcoin? In Oliver’s mind, the answer is simple: games that don’t feel preachy but still plant the orange pill.

Learn more at Jippi.app

That’s exactly what Jippi is. Based in Austin, Texas, the team has created a mobile augmented reality (AR) game that rewards players in bitcoin and sneakily teaches them why sound money matters.

“It’s Pokémon GO… but for sats,” Oliver puts it succinctly.

Jippi is like Pokemon Go, but for sats

Oliver’s Bitcoin journey, like many in the space, began long before he was ready. A former colleague had tried planting the seed years earlier, handing him a copy of The Bitcoin Standard. But the moment passed.

It wasn’t until the chaos of 2020 when lockdowns hit, printing presses roared, and civil liberties shrank that the message finally landed for him.

“The government got so good at doing reverse Robin Hood,” Oliver explains. “They steal from the working population and reward the rich.”

By 2020, though, the absurdity of the covid hysteria had caused his eyes to be opened and the orange light seemed the best path back to freedom.

He left the UK for Austin “one of the best places for Bitcoiners,” he says, and dove headfirst into the industry, working at Swan for a year before founding Jippi on PlebLab’s accelerator program.

Jippi’s flagship game lets players roam their cities hunting digital creatures, Bitcoin Beasts, tied to real-world locations. Catching them requires answering Bitcoin trivia, and the reward is sats.

No jargon. No hour-long lectures. Just gameplay with sound money principles woven right in.

The model is working. At a recent hackathon in Austin, Jippi beat out 14 other teams to win first place and $15,000 in prize money.

Oliver of Jippi won Top Builder Season 2 — PlebLab on X

“We’re backdooring Bitcoin education,” Oliver admits. “And while we’re at it, encouraging people to get outside and touch grass.”

Not everyone’s been thrilled. When Jippi team members visited one of the more liberal-leaning places in Texas, UT Austin, to test interest in Bitcoin, they found some seriously committed no-coiners on the campus.

“One young woman told me, ‘I would rather die than talk about Bitcoin,'” Oliver recalls, highlighting the cultural resistance that’s built up among younger demographics.

This resistance is backed by hard data. According to Oliver, some of the Bitcoin podcasters they met with in the space to do market research reported that less than 1% of their listeners are from Gen Z and that number is dropping.

“Unless we find a way to capture their interest in a meaningful way, there’s going to be a big problem around trying to sway Gen Z away from the siren call of s***coins and crypto casinos and towards Bitcoin,” Oliver warns.

Jippi’s next big move is Las Vegas, where they’ll launch the Beast Catch experience at the Venetian during a major Bitcoin event. To mark the occasion, they’re opening up six limited sponsorship spots for Bitcoin companies, each one tied to a custom in-game beast.

Jippi looks to launch a special event at Bitcoin 2025

“It’s real estate inside the game,” Oliver explains. “Brands become allies, not intrusions. You get a logo, company name, and call to action, so we can push people to your site or app.”

Bitcoin Well—an automatic self-custody Bitcoin platform—has claimed Beast #1. Only five exclusive spots remain for Bitcoin companies to “beastify their brand” through Jippi’s immersive AR game.

“I love the Jippi mission. I think gamified learning is how we will onboard the next generation and it’s exciting to see what the Jippi team is doing! I love working with bitcoiners towards our common mission – bullish!” said Adam O’Brien, Bitcoin Well CEO.

Jippi’s sponsorship model is simple: align incentives, respect users, and support builders. Instead of throwing ad money at tech giants, Bitcoin companies can connect with new users naturally while they’re having fun and earning sats in the process.

For Bitcoin companies looking to reach a younger demographic, this represents a unique opportunity to showcase their brand to up to 30,000 potential customers at the Vegas event.

Jippi Bitcoin Beast partnership

While Jippi’s current focus is simple, get the game into more cities, Oliver sees a future where AR glasses and AI help personalize Bitcoin education even further.

“The magic is going to really happen when Apple releases the glasses form factor,” he says, describing how augmented reality could enhance real-world connections rather than isolate users.

In the longer term, Jippi aims to evolve from a free-to-play model toward a pay-to-play version with higher stakes. Users would form “tribes” with friends to compete for substantial bitcoin prizes, creating social connections along with financial education.

Unlike VC-backed startups, Jippi is raising funds pleb style via Timestamp, an open investment platform for Bitcoin companies.

“You don’t have to be an accredited investor,” Oliver explains. “You’re directly supporting the parallel Bitcoin economy by investing in Bitcoin companies for equity.”

Anyone can invest as little as $100. Perks include early access, exclusive game content, and even creating your own beast design with your name/pseudonym and unique game lore. Each investment comes with direct ownership of an early-stage Bitcoin company like Jippi.

For Oliver, this is more than just a business. It’s about future-proofing Bitcoin adoption and ensuring Satoshi’s vision lives on, especially as many people are lured by altcoins, NFTs, and social media dopamine.

“We’re on the right side of history,” he says firmly. “I want my grandkids to know that early on in the Bitcoin revolution, games like Jippi helped make it stick.”

In a world increasingly absorbed by screens and short attention spans, Jippi’s combination of outdoor play, sats rewards, and Bitcoin education might be exactly the bridge Gen Z needs.

Chef's notes

I found this recipe a couple years ago and have been addicted to it since. Its incredibly easy, and cheap to prep. Freeze the sausage in flat, single serving portions. That way it can be cooked from frozen for a fast, flavorful, and healthy lunch or dinner. I took inspiration from the video that contained this recipe, and almost always pan fry the frozen sausage with some baby broccoli. The steam cooks the broccoli and the fats from the sausage help it to sear, while infusing the vibrant flavors. Serve with some rice, if desired. I often use serrano peppers, due to limited produce availability. They work well for a little heat and nice flavor that is not overpowering.

Details

• ⏲️ Prep time: 25 min
• 🍳 Cook time: 15 min (only needed if cooking at time of prep)
• 🍽️ Servings: 10

Ingredients

• 4 lbs ground pork
• 12-15 cloves garlic, minced
• 6 Thai or Serrano peppers, rough chopped
• 1/4 c. lime juice
• 4 Tbsp fish sauce
• 1 Tbsp brown sugar
• 1/2 c. chopped cilantro

Directions

1. Mix all ingredients in a large bowl.
2. Portion and freeze, as desired.
3. Sautè frozen portions in hot frying pan, with broccoli or other fresh veggies.
4. Serve with rice or alone.

At the recent Launch Music Festival and Conference in Lancaster, PA, featuring over 120 musicians across three days, I volunteered my time with Tunestr and Phantom Power Music's initiative to introduce artists to Bitcoin, Nostr, and the value-for-value model. Tunestr sponsored a stage, live-streaming 21 bands to platforms like Tunestr.io, Fountain.fm and other Nostr/Podcasting 2.0 apps and on-boarding as many others as possible at our conference booth. You may have seen me spamming about this over the last few days.

V4V Earnings

Day 1: 180,000 sats

Day 2: 300,000 sats

Day 3: Over 500,000 sats

Many more musicians were on-boarded to Fountain, however, we were unable to obtain all of their npubs.

THANK YOU TO ALL ZAPPERS AND BOOSTERS!

Musicians “Get It”

My key takeaway was the musicians' absolute understanding that the current digital landscape along with legacy social media is failing them. Every artist I spoke with recognized how algorithms hinder fan connection and how gatekeepers prevent fair compensation for their work. They all use Spotify, but they only do so out of necessity. They felt the music industry is primed for both a social and monetary revolution. Some of them were even speaking my language…

Because of this, concepts like decentralization, censorship resistance, owning your content, and controlling your social graph weren't just understood by them, they were instantly embraced. The excitement was real; they immediately saw the potential and agreed with me. Bitcoin and Nostr felt genuinely punk rock and that helped a lot of them identify with what we were offering them.

The Tools and the Issues

While the Nostr ecosystem offers a wide variety of tools, we focused on introducing three key applications at this event to keep things clear for newcomers:

1. Fountain, with a music focus, was the primary tool for onboarding attendees onto Nostr. Fountain was also chosen thanks to Fountain’s built-in Lightning wallet.
2. Primal, as a social alternative, was demonstrated to show how users can take their Nostr identity and content seamlessly between different applications.
3. Tunestr.io, lastly was showcased for its live video streaming capabilities.

Although we highlighted these three, we did inform attendees about the broader range of available apps and pointed them to nostrapps.com if they wanted to explore further, aiming to educate without overwhelming them.

This review highlights several UX issues with the Fountain app, particularly concerning profile updates, wallet functionality, and user discovery. While Fountain does work well, these minor hiccups make it extremely hard for on-boarding and education.

• Profile Issues:
• When a user edits their profile (e.g., Username/Nostr address, Lightning address) either during or after creation, the changes don't appear to consistently update across the app or sync correctly with Nostr relays.
• Specifically, the main profile display continues to show the old default Username/Nostr address and Lightning address inside Fountain and on other Nostr clients.
• However, the updated Username/Nostr address does appear on https://fountain.fm (chosen-username@fountain.fm) and is visible within the "Edit Profile" screen itself in the app.
• This inconsistency is confusing for users, as they see their updated information in some places but not on their main public-facing profile within the app. I confirmed this by observing a new user sign up and edit their username – the edit screen showed the new name, but the profile display in Fountain did not update and we did not see it inside Primal, Damus, Amethyst, etc.
• Wallet Limitations:
• The app's built-in wallet cannot scan Lightning address QR codes to initiate payments.
• This caused problems during the event where users imported Bitcoin from Azte.co vouchers into their Fountain wallets. When they tried to Zap a band by scanning a QR code on the live tally board, Fountain displayed an error message stating the invoice or QR code was invalid.
• While suggesting musicians install Primal as a second Nostr app was a potential fix for the QR code issue, (and I mentioned it to some), the burden of onboarding users onto two separate applications, potentially managing two different wallets, and explaining which one works for specific tasks creates a confusing and frustrating user experience.
• Search Difficulties:
• Finding other users within the Fountain app is challenging. I was unable to find profiles from brand new users by entering their chosen Fountain username.
• To find a new user, I had to resort to visiting their profile on the web (fountain.fm/username) to retrieve their npub. Then, open Primal and follow them. Finally, when searching for their username, since I was now following them, I was able to find their profile.
• This search issue is compounded by the profile syncing problem mentioned earlier, as even if found via other clients, their displayed information is outdated.
• Searching for the event to Boost/Zap inside Fountain was harder than it should have been the first two days as the live stream did not appear at the top of the screen inside the tap. This was resolved on the third day of the event.

Improving the Onboarding Experience

To better support user growth, educators and on-boarders need more feature complete and user-friendly applications. I love our developers and I will always sing their praises from the highest mountain tops, however I also recognize that the current tools present challenges that hinder a smooth onboarding experience.

One potential approach explored was guiding users to use Primal (including its built-in wallet) in conjunction with Wavlake via Nostr Wallet Connect (NWC). While this could facilitate certain functions like music streaming, zaps, and QR code scanning (which require both Primal and Wavlake apps), Wavlake itself has usability issues. These include inconsistent or separate profiles between web and mobile apps, persistent "Login" buttons even when logged in on the mobile app with a Nostr identity, and the minor inconvenience of needing two separate applications. Although NWC setup is relatively easy and helps streamline the process, the need to switch between apps adds complexity, especially when time is limited and we’re aiming to showcase the benefits of this new system.

Ultimately, we need applications that are more feature-complete and intuitive for mainstream users to improve the onboarding experience significantly.

Looking forward to the future

I anticipate that most of these issues will be resolved when these applications address them in the near future. Specifically, this would involve Fountain fixing its profile issues and integrating Nostr Wallet Connect (NWC) to allow users to utilize their Primal wallet, or by enabling the scanning of QR codes that pay out to Lightning addresses. Alternatively, if Wavlake resolves the consistency problems mentioned earlier, this would also significantly improve the situation giving us two viable solutions for musicians.

My ideal onboarding event experience would involve having all the previously mentioned issues resolved. Additionally, I would love to see every attendee receive a $5 or $10 voucher to help them start engaging with value-for-value, rather than just the limited number we distributed recently. The goal is to have everyone actively zapping and sending Bitcoin throughout the event. Maybe we can find a large sponsor to facilitate this in the future?

What's particularly exciting is the Launch conference's strong interest in integrating value-for-value across their entire program for all musicians and speakers at their next event in Dallas, Texas, coming later this fall. This presents a significant opportunity to onboard over 100+ musicians to Bitcoin and Nostr, which in turn will help onboard their fans and supporters.

We need significantly more zaps and more zappers! It's unreasonable to expect the same dedicated individuals to continuously support new users; they are being bled dry. A shift is needed towards more people using bitcoin for everyday transactions, treating it as money. This brings me back to my ideal onboarding experience: securing a sponsor to essentially give participants bitcoin funds specifically for zapping and tipping artists. This method serves as a practical lesson in using bitcoin as money and showcases the value-for-value principle from the outset.

“Our world of widows needs to be saved / it’s now or never — victim or victory, rebel or regret / who you are and who you claim to be / no more heroes.” -Converge, “No Heroes”

Usually, bad takes from big figures in the Bitcoin space roll off my back. I often don’t feel a need to counter them because 1.) Everyone is entitled to their opinion and 2.) I don’t enjoy spending my time arguing with people on the Internet.

But when a take is really bad — downright evil — I feel compelled to respond.

And respond I did to a bad take this week (link in just a second, first some context).

Lately in the media, MicroStrategy Chair Michael Saylor has been laying out his vision for a digital asset framework.

This framework includes conceptualizing Bitcoin as a commodity — nothing more than capital — and stablecoins like Tether (USDT) and USD Coin (USDC) as “digital currencies” (his words).

As if someone who considers themselves a “triple bitcoin maxi” (maybe one of the lamest terms ever) denying that bitcoin is a currency weren’t nauseating enough, his “evil genius plan” (his words) to get the world hooked on USD stablecoins as money while the US hoards bitcoin should have you upchuck everything in your guts if you truly believe in Bitcoin’s value proposition.

Below (a few lines down) is the piece I wrote countering Saylor’s perspective.

If there are two things I hope you take away from it, the first is to KILL YOUR IDOLS (not literally, of course) and the second is that WE ARE BITCOIN, and if we believe in the technology — all dimensions of it — we have to defend it.

Enjoy.

Bitcoin’s Second Book-Length Academic Text — The Satoshi Papers — Coming Soon

This week, I published my interview with Natalie Smolenski, a PhD-holding theoretical anthropologist who often makes very valuable thought contributions to the Bitcoin space.

The Satoshi Papers Explores The Role Of The State In A Post-Bitcoin World: An Interview With Natalie Smolenski

What I loved most about this interview (and I loved a lot about it) is Smolenski’s lack of reverence.

Two of my favorite quotes from the interview:

“There was kind of a triumph of a certain very statist approach to socialism and even communism in the American academy, in the Anglophone academy, that has persisted to this day, where there's, like I was saying earlier, a suspicion of anything smacking of individualism as bourgeois conceit or reinscribing social hierarchies, racial hierarchies, gender hierarchies, blah, blah, blah.”

The “blah, blah, blah” hit hard. It reminded me of how I used to tune out when speaking with a good portion of my co-workers during the years I taught at the college level.

The other one:

“What do you hope people will take away from The Satoshi Papers?

*> If there's only one idea that people take away from it, it's that your emancipation does not require the state. You do not need to wait for the government.

*> My God, take control of your life. You can, it is within your power to do so, and here are some examples of ways that people throughout human history have chosen to do so."

The “My God” was so properly placed. Chef’s kiss.

Check out to entire piece to absorb more of Smolenski’s wisdom.

Thank you all for reading, and here’s to a great week ahead!

Best,

Frank

And what does it mean to withdraw back to Bitcoin Layer 1?

Disclaimer: This post was written with help from ChatGPT-4o. If you spot any mistakes or have suggestions — feel free to reply or zap in feedback!

Let’s break it down — using three popular setups:

---

1. Wallet of Satoshi (WoS)

Custodial — you don’t touch Lightning directly

Sending sats:

• You open WoS, paste a Lightning invoice, hit send.
• WoS handles the payment entirely within their system.
• If recipient uses WoS: internal balance update.
• If external: routed via their node.
• You never open channels, construct routes, or sign anything.

Withdrawing to L1:

• You paste a Bitcoin address.
• WoS sends a regular on-chain transaction from their custodial wallet.
• You pay a fee. It’s like a bank withdrawal.

You don’t interact with Lightning directly. Think of it as a trusted 3rd party Lightning “bank”.

---

2. Phoenix Wallet

Non-custodial — you own keys, Phoenix handles channels

Sending sats:

• You scan a Lightning invoice and hit send.
• Phoenix uses its backend node (ACINQ) to route the payment.
• If needed, it opens a real 2-of-2 multisig channel on-chain automatically.
• You own your keys (12-word seed), Phoenix abstracts the technical parts.

Withdrawing to L1:

• You enter your Bitcoin address.
• Phoenix closes your Lightning channel (cooperatively, if possible).
• Your sats are sent as a real Bitcoin transaction to your address.

You’re using Lightning “for real,” with real Bitcoin channels — but Phoenix smooths out the UX.

---

3. Your Own Lightning Node

Self-hosted — you control everything

Sending sats:

• You manage your channels manually (or via automation).
• Your node:
• Reads the invoice
• Builds a route using HTLCs
• Sends the payment using conditional logic (preimages, time locks).
• If routing fails: retry or adjust liquidity.

Withdrawing to L1:

• You select and close a channel.
• A channel closing transaction is broadcast:
• Cooperative = fast and cheap
• Force-close = slower, more expensive, and time-locked
• Funds land in your on-chain wallet.

You have full sovereignty — but also full responsibility (liquidity, fees, backups, monitoring).

---

Core Tech Behind It: HTLCs, Multisig — and No Sidechain

• Lightning channels = 2-of-2 multisig Bitcoin addresses
• Payments = routed via HTLCs (Hashed Time-Locked Contracts)
• HTLCs are off-chain, but enforceable on-chain if needed
• Important:
• The Lightning Network is not a sidechain.
• It doesn't use its own token, consensus, or separate blockchain.
• Every Lightning channel is secured by real Bitcoin on L1.

Lightning = fast, private, off-chain Bitcoin — secured by Bitcoin itself.

---

Summary Table

| Wallet | Custody | Channel Handling | L1 Withdrawal | HTLC Visibility | User Effort | |--------------------|--------------|------------------------|---------------------|------------------|--------------| | Wallet of Satoshi | Custodial | None | Internal to external| Hidden | Easiest | | Phoenix Wallet | Non-custodial| Auto-managed real LN | Channel close | Abstracted | Low effort | | Own Node | You | Manual | Manual channel close| Full control | High effort |

---

Bonus: Withdrawing from LN to On-Chain

• WoS: sends sats from their wallet — like PayPal.
• Phoenix: closes a real channel and sends your UTXO on-chain.
• Own node: closes your multisig contract and broadcasts your pre-signed tx.

---

Bitcoin + Lightning = Sovereign money + Instant payments.
Choose the setup that fits your needs — and remember, you can always level up later.

P.S. What happens in Lightning... usually stays in Lightning.

Use this guide if you want to keep your NixOS on the stable branch, but enable unstable application packages. It took me a while to figure out how to do this, so I wanted to share because it ended up being far easier than most of the vague explanations online made it seem.

I put a sample configuration.nix file at the very bottom to help it make more sense for new users. Remember to keep a backup of your config file, just in case!

If there are any errors please let me know. I am currently running NixOS 24.11.

Steps listed in this guide: 1. Add the unstable channel to NixOS as a secondary channel. 2. Edit the configuration.nix to enable unstable applications. 3. Add "unstable." in front of the application names in the config file (example: unstable.program). This enables the install of unstable versions during the build. 4. Rebuild.

Step 1:

• Open the console. (If you want to see which channels you currently have, type: sudo nix-channel --list)
• Add the unstable channel, type: sudo nix-channel --add https://channels.nixos.org/nixpkgs-unstable unstable
• To update the channels (bring in the possible apps), type: sudo nix-channel --update

More info here: https://nixos.wiki/wiki/Nix_channels

Step 2:

Edit your configuration.nix and add the following around your current config:

``` { config, pkgs, lib, ... }:

let unstable = import { config = { allowUnfree = true; }; }; in {

    #insert normal configuration text here

  } #remember to close the bracket!

```

At this point it would be good to save your config and try a rebuild to make sure there are no errors. If you have errors, make sure your brackets are in the right places and/or not missing. This step will make for less troubleshooting later on if something happens to be in the wrong spot!

Step 3:

Add "unstable." to the start of each application you want to use the unstable version. (Example: unstable.brave)

Step 4:

Rebuild your config, type: sudo nixos-rebuild switch

---

Example configuration.nix file:

```

Config file for NixOS

{ config, pkgs, lib, ... }:

Enable unstable apps from Nix repository.

let unstable = import { config = { allowUnfree = true; }; }; in {

#Put your normal config entries here in between the tags. Below is what your applications list needs to look like.

environment.systemPackages = with pkgs; [ appimage-run blender unstable.brave #Just add unstable. before the application name to enable the unstable version. chirp discord ];

} # Don't forget to close bracket at the end of the config file!

``` That should be all. Hope it helps.

While I’m going to stand by what I said in my previous piece, minimise capital gains payments, don’t fund the government, get a loan against your bitcoin, but the wheels in my left curve brain have continued to turn, well that, and a few more of my 40PW insights. I mentioned about paying attention to the risks involved in terms of borrowing against your bitcoin, and hopefully ending up paying less in bitcoin at the end of the loan, even if you ultimately sold bitcoin to pay off the loan. However, the idea of losing control of the bitcoin I have spent a good deal of time and effort accumulating being out of my control has led me to reconsider. I also realised I didn’t fully flesh out some other topics that I think are relevant, not least time preference, specifically in relation to what you’re buying. The idea of realising a lump some of capital to live your dreams, buy a house or a cool car may be important, but it may be worth taking a step back and looking at what you’re purchasing. Are you only purchasing those things because you had been able to get this new money “tax free”? If that is the case, and the fiat is burning a hold in your pocket, maybe you’ve just found yourself with the same fiat brained mentality you have been working so hard to escape from while you have sacrificed and saved to stack sats.

While it may no longer be necessary to ask yourself whether a particular product or service is worth selling your bitcoin for because you’ve taken out a loan, it may still be worth asking yourself whether a particular loan fuelled purchase is worth forfeiting control of your keys for? Unlike the foolish 18 year-old, released into a world with their newly preapproved credit card, you need to take a moment and ask yourself:

Is the risk worth it?

Is the purchase worth it?

But also take a moment to consider a number of other things, are there fiat options?

Where in the cycle might you be?

Or if I’m thinking carefully about this, will whatever I’m buying hold its value (experiences may be more difficult to run the numbers on)?

The reason for asking these things, is that if you still have a foot in the fiat world, dealing with a fiat bank account, fiat institutions may still be very willing to provide you with a loan at a lower rate than a bitcoin backed loan. Particularly if you’re planning on using that money to buy a house; if you can qualify for a mortgage, get a mortgage, but if you need cash for a deposit, maybe that is where the bitcoin backed loan may come in. Then, it may be worth thinking about where are you in the bitcoin cycle? No one can answer this, but with the historic data we have, it appears logical that after some type of run up, prices may retrace (Dan Held’s supercycle withstanding).

Matteo Pellegrini with Daniel Prince provided a new perspective on this for me. Rather the riding the bull market gains all the way through to the bear market bottom, what happens if I chose to buy an asset that didn’t lose quite as much fiat value as bitcoin, for example, a Swiss Watch, or a tasteful, more mature sports car? If that was the purchase of choice, they suggested that you could enjoy the car, “the experience” for a year or two, then realise the four door estate was likely always the better option, sell it and be able to buy back as many, if not slightly more bitcoin that you originally sold (not financial, classic car or price prediction advice, I’m not accredited to advise pretty much anything). Having said that, it is a scenario I think worth thinking about when the bitcoin denominated dream car begins to make financial sense.

Then, as we begin to look forward to the near inevitable bear market (they are good for both stacking and grinding), if we’ve decided to take out a loan rather than sell, we then may ultimately need to increase our collateral to maintain loan to value requirements, as well as sell more bitcoin to cover repayments (if that’s the route we’re taking). This then moves us back into the domain of saying, well in actual fact we should just sell our bitcoin when we can get most dollar for it (or the coolest car), with a little extra to cover future taxes, it is probably better to sell near a top than a bottom. The balance between these two rather extreme positions could be to take out a fiat loan to buy the item and maybe sell sufficient bitcoin so you’re able to cover the loan for a period of time (less taxable events to keep track of and also deals with future uncertainty of bitcoin price). In this case, if the loan timeframe is longer than the amount of loan your sale can cover, by the time you need to sell anymore, the price should have recovered from a cycle bottom.

In this scenario, apart from the smaller portion of bitcoin you have had to sell, the majority of your stack can remain in cold storage, the loan you took out will be unsecured (particularly against your bitcoin), but even if it isn’t, the value of what you purchase maintains its value, you can in theory exit the loan at any point by selling the luxury item. Then within this scenario, if you had sold near a top, realised the car gave you a bad back or made you realise you staying humble is more important, sold it, paid off the loan, there may even be a chance you could buy back more bitcoin with the money you had left over from selling your bitcoin to fund the loan.

I have no idea of this could actually work, but to be honest, I’m looking forward to trying it out in the next 6-12 months, although I may keep my daily driver outside of my bitcoin strategy (kids still need a taxi service). Having said that, I think there are some important points to consider in addition to not paying capital gains tax (legally), as well as the opportunities of bitcoin loans. They are still very young products and to quote every trad-fi news outlet, “bitcoin is still a volatile asset”, these thought experiments are still worth working through. To push back on the Uber fiat journalist, Katie Martin, “Bitcoin has no obvious use case”, it does, it can be a store of value to hold or sell, it can be liquid and flexible collateral, but also an asset that moves independently of other assets to balance against fiat liabilities. The idea of being able to release some capital, enjoy the benefits of the capital for a period, before returning that capital to store value feels like a compelling one.

The important thing to remember is that there are a variety of options, whether selling for cash, taking out a bitcoin backed loan, taking out a fiat loan or some combination of each. Saying that, what I would think remains an important question to ask irrespective of the option you go for:

Is what I’m planning on buying, worth selling bitcoin for?

If it cannot pass this first question, maybe it isn’t worth purchasing to start with.

Para distribuir os dados, metadados e dados do sistema em todos os dispositivos de armazenamento do RAID (incluindo o dispositivo de armazenamento recém-adicionado) montados no diretório /data , execute o seguinte comando:

sudo btrfs balance start --full-balance /data

Pode demorar um pouco para espalhar os dados, metadados e dados do sistema em todos os dispositivos de armazenamento do RAID se ele contiver muitos dados.

Opções importantes de montagem Btrfs

Nesta seção, vou explicar algumas das importantes opções de montagem do Btrfs. Então vamos começar.

As opções de montagem Btrfs mais importantes são:

**1. acl e noacl

**ACL gerencia permissões de usuários e grupos para os arquivos/diretórios do sistema de arquivos Btrfs.

A opção de montagem acl Btrfs habilita ACL. Para desabilitar a ACL, você pode usar a opção de montagem noacl .

Por padrão, a ACL está habilitada. Portanto, o sistema de arquivos Btrfs usa a opção de montagem acl por padrão.

**2. autodefrag e noautodefrag

**Desfragmentar um sistema de arquivos Btrfs melhorará o desempenho do sistema de arquivos reduzindo a fragmentação de dados.

A opção de montagem autodefrag permite a desfragmentação automática do sistema de arquivos Btrfs.

A opção de montagem noautodefrag desativa a desfragmentação automática do sistema de arquivos Btrfs.

Por padrão, a desfragmentação automática está desabilitada. Portanto, o sistema de arquivos Btrfs usa a opção de montagem noautodefrag por padrão.

**3. compactar e compactar-forçar

**Controla a compactação de dados no nível do sistema de arquivos do sistema de arquivos Btrfs.

A opção compactar compacta apenas os arquivos que valem a pena compactar (se compactar o arquivo economizar espaço em disco).

A opção compress-force compacta todos os arquivos do sistema de arquivos Btrfs, mesmo que a compactação do arquivo aumente seu tamanho.

O sistema de arquivos Btrfs suporta muitos algoritmos de compactação e cada um dos algoritmos de compactação possui diferentes níveis de compactação.

Os algoritmos de compactação suportados pelo Btrfs são: lzo , zlib (nível 1 a 9) e zstd (nível 1 a 15).

Você pode especificar qual algoritmo de compactação usar para o sistema de arquivos Btrfs com uma das seguintes opções de montagem:

• compress=algoritmo:nível
• compress-force=algoritmo:nível

Para obter mais informações, consulte meu artigo Como habilitar a compactação do sistema de arquivos Btrfs .

**4. subvol e subvolid

**Estas opções de montagem são usadas para montar separadamente um subvolume específico de um sistema de arquivos Btrfs.

A opção de montagem subvol é usada para montar o subvolume de um sistema de arquivos Btrfs usando seu caminho relativo.

A opção de montagem subvolid é usada para montar o subvolume de um sistema de arquivos Btrfs usando o ID do subvolume.

Para obter mais informações, consulte meu artigo Como criar e montar subvolumes Btrfs .

**5. dispositivo

A opção de montagem de dispositivo** é usada no sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs.

Em alguns casos, o sistema operacional pode falhar ao detectar os dispositivos de armazenamento usados em um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs. Nesses casos, você pode usar a opção de montagem do dispositivo para especificar os dispositivos que deseja usar para o sistema de arquivos de vários dispositivos Btrfs ou RAID.

Você pode usar a opção de montagem de dispositivo várias vezes para carregar diferentes dispositivos de armazenamento para o sistema de arquivos de vários dispositivos Btrfs ou RAID.

Você pode usar o nome do dispositivo (ou seja, sdb , sdc ) ou UUID , UUID_SUB ou PARTUUID do dispositivo de armazenamento com a opção de montagem do dispositivo para identificar o dispositivo de armazenamento.

Por exemplo,

• dispositivo=/dev/sdb
• dispositivo=/dev/sdb,dispositivo=/dev/sdc
• dispositivo=UUID_SUB=490a263d-eb9a-4558-931e-998d4d080c5d
• device=UUID_SUB=490a263d-eb9a-4558-931e-998d4d080c5d,device=UUID_SUB=f7ce4875-0874-436a-b47d-3edef66d3424

**6. degraded

A opção de montagem degradada** permite que um RAID Btrfs seja montado com menos dispositivos de armazenamento do que o perfil RAID requer.

Por exemplo, o perfil raid1 requer a presença de 2 dispositivos de armazenamento. Se um dos dispositivos de armazenamento não estiver disponível em qualquer caso, você usa a opção de montagem degradada para montar o RAID mesmo que 1 de 2 dispositivos de armazenamento esteja disponível.

**7. commit

A opção commit** mount é usada para definir o intervalo (em segundos) dentro do qual os dados serão gravados no dispositivo de armazenamento.

O padrão é definido como 30 segundos.

Para definir o intervalo de confirmação para 15 segundos, você pode usar a opção de montagem commit=15 (digamos).

**8. ssd e nossd

A opção de montagem ssd** informa ao sistema de arquivos Btrfs que o sistema de arquivos está usando um dispositivo de armazenamento SSD, e o sistema de arquivos Btrfs faz a otimização SSD necessária.

A opção de montagem nossd desativa a otimização do SSD.

O sistema de arquivos Btrfs detecta automaticamente se um SSD é usado para o sistema de arquivos Btrfs. Se um SSD for usado, a opção de montagem de SSD será habilitada. Caso contrário, a opção de montagem nossd é habilitada.

**9. ssd_spread e nossd_spread

A opção de montagem ssd_spread** tenta alocar grandes blocos contínuos de espaço não utilizado do SSD. Esse recurso melhora o desempenho de SSDs de baixo custo (baratos).

A opção de montagem nossd_spread desativa o recurso ssd_spread .

O sistema de arquivos Btrfs detecta automaticamente se um SSD é usado para o sistema de arquivos Btrfs. Se um SSD for usado, a opção de montagem ssd_spread será habilitada. Caso contrário, a opção de montagem nossd_spread é habilitada.

**10. descarte e nodiscard

Se você estiver usando um SSD que suporte TRIM enfileirado assíncrono (SATA rev3.1), a opção de montagem de descarte** permitirá o descarte de blocos de arquivos liberados. Isso melhorará o desempenho do SSD.

Se o SSD não suportar TRIM enfileirado assíncrono, a opção de montagem de descarte prejudicará o desempenho do SSD. Nesse caso, a opção de montagem nodiscard deve ser usada.

Por padrão, a opção de montagem nodiscard é usada.

**11. norecovery

Se a opção de montagem norecovery** for usada, o sistema de arquivos Btrfs não tentará executar a operação de recuperação de dados no momento da montagem.

**12. usebackuproot e nousebackuproot

Se a opção de montagem usebackuproot for usada, o sistema de arquivos Btrfs tentará recuperar qualquer raiz de árvore ruim/corrompida no momento da montagem. O sistema de arquivos Btrfs pode armazenar várias raízes de árvore no sistema de arquivos. A opção de montagem usebackuproot** procurará uma boa raiz de árvore e usará a primeira boa que encontrar.

A opção de montagem nousebackuproot não verificará ou recuperará raízes de árvore inválidas/corrompidas no momento da montagem. Este é o comportamento padrão do sistema de arquivos Btrfs.

**13. space_cache, space_cache=version, nospace_cache e clear_cache

A opção de montagem space_cache** é usada para controlar o cache de espaço livre. O cache de espaço livre é usado para melhorar o desempenho da leitura do espaço livre do grupo de blocos do sistema de arquivos Btrfs na memória (RAM).

O sistema de arquivos Btrfs suporta 2 versões do cache de espaço livre: v1 (padrão) e v2

O mecanismo de cache de espaço livre v2 melhora o desempenho de sistemas de arquivos grandes (tamanho de vários terabytes).

Você pode usar a opção de montagem space_cache=v1 para definir a v1 do cache de espaço livre e a opção de montagem space_cache=v2 para definir a v2 do cache de espaço livre.

A opção de montagem clear_cache é usada para limpar o cache de espaço livre.

Quando o cache de espaço livre v2 é criado, o cache deve ser limpo para criar um cache de espaço livre v1 .

Portanto, para usar o cache de espaço livre v1 após a criação do cache de espaço livre v2 , as opções de montagem clear_cache e space_cache=v1 devem ser combinadas: clear_cache,space_cache=v1

A opção de montagem nospace_cache é usada para desabilitar o cache de espaço livre.

Para desabilitar o cache de espaço livre após a criação do cache v1 ou v2 , as opções de montagem nospace_cache e clear_cache devem ser combinadas: clear_cache,nosapce_cache

**14. skip_balance

Por padrão, a operação de balanceamento interrompida/pausada de um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs será retomada automaticamente assim que o sistema de arquivos Btrfs for montado. Para desabilitar a retomada automática da operação de equilíbrio interrompido/pausado em um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs, você pode usar a opção de montagem skip_balance .**

**15. datacow e nodatacow

A opção datacow** mount habilita o recurso Copy-on-Write (CoW) do sistema de arquivos Btrfs. É o comportamento padrão.

Se você deseja desabilitar o recurso Copy-on-Write (CoW) do sistema de arquivos Btrfs para os arquivos recém-criados, monte o sistema de arquivos Btrfs com a opção de montagem nodatacow .

**16. datasum e nodatasum

A opção datasum** mount habilita a soma de verificação de dados para arquivos recém-criados do sistema de arquivos Btrfs. Este é o comportamento padrão.

Se você não quiser que o sistema de arquivos Btrfs faça a soma de verificação dos dados dos arquivos recém-criados, monte o sistema de arquivos Btrfs com a opção de montagem nodatasum .

Perfis Btrfs

Um perfil Btrfs é usado para informar ao sistema de arquivos Btrfs quantas cópias dos dados/metadados devem ser mantidas e quais níveis de RAID devem ser usados para os dados/metadados. O sistema de arquivos Btrfs contém muitos perfis. Entendê-los o ajudará a configurar um RAID Btrfs da maneira que você deseja.

Os perfis Btrfs disponíveis são os seguintes:

single : Se o perfil único for usado para os dados/metadados, apenas uma cópia dos dados/metadados será armazenada no sistema de arquivos, mesmo se você adicionar vários dispositivos de armazenamento ao sistema de arquivos. Assim, 100% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser utilizado.

dup : Se o perfil dup for usado para os dados/metadados, cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos manterá duas cópias dos dados/metadados. Assim, 50% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser utilizado.

raid0 : No perfil raid0 , os dados/metadados serão divididos igualmente em todos os dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, não haverá dados/metadados redundantes (duplicados). Assim, 100% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser usado. Se, em qualquer caso, um dos dispositivos de armazenamento falhar, todo o sistema de arquivos será corrompido. Você precisará de pelo menos dois dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid0 .

raid1 : No perfil raid1 , duas cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a uma falha de unidade. Mas você pode usar apenas 50% do espaço total em disco. Você precisará de pelo menos dois dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1 .

raid1c3 : No perfil raid1c3 , três cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a duas falhas de unidade, mas você pode usar apenas 33% do espaço total em disco. Você precisará de pelo menos três dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1c3 .

raid1c4 : No perfil raid1c4 , quatro cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a três falhas de unidade, mas você pode usar apenas 25% do espaço total em disco. Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1c4 .

raid10 : No perfil raid10 , duas cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos, como no perfil raid1 . Além disso, os dados/metadados serão divididos entre os dispositivos de armazenamento, como no perfil raid0 .

O perfil raid10 é um híbrido dos perfis raid1 e raid0 . Alguns dos dispositivos de armazenamento formam arrays raid1 e alguns desses arrays raid1 são usados para formar um array raid0 . Em uma configuração raid10 , o sistema de arquivos pode sobreviver a uma única falha de unidade em cada uma das matrizes raid1 .

Você pode usar 50% do espaço total em disco na configuração raid10 . Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid10 .

raid5 : No perfil raid5 , uma cópia dos dados/metadados será dividida entre os dispositivos de armazenamento. Uma única paridade será calculada e distribuída entre os dispositivos de armazenamento do array RAID.

Em uma configuração raid5 , o sistema de arquivos pode sobreviver a uma única falha de unidade. Se uma unidade falhar, você pode adicionar uma nova unidade ao sistema de arquivos e os dados perdidos serão calculados a partir da paridade distribuída das unidades em execução.

Você pode usar 1 00x(N-1)/N % do total de espaços em disco na configuração raid5 . Aqui, N é o número de dispositivos de armazenamento adicionados ao sistema de arquivos. Você precisará de pelo menos três dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid5 .

raid6 : No perfil raid6 , uma cópia dos dados/metadados será dividida entre os dispositivos de armazenamento. Duas paridades serão calculadas e distribuídas entre os dispositivos de armazenamento do array RAID.

Em uma configuração raid6 , o sistema de arquivos pode sobreviver a duas falhas de unidade ao mesmo tempo. Se uma unidade falhar, você poderá adicionar uma nova unidade ao sistema de arquivos e os dados perdidos serão calculados a partir das duas paridades distribuídas das unidades em execução.

Você pode usar 100x(N-2)/N % do espaço total em disco na configuração raid6 . Aqui, N é o número de dispositivos de armazenamento adicionados ao sistema de arquivos. Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid6 .

สวัสดีค่ะเพื่อนๆ นักเทรดที่น่ารักทุกคน! 💕 Lina Engword กลับมาพร้อมกับการวิเคราะห์ BTCUSDT.P แบบเจาะลึกเพื่อเตรียมพร้อมสำหรับเทรดวันนี้ค่ะ! 🚀

วันนี้ 12 พฤษภาคม 2568 เวลา 08.15น. ราคา BTCUSDT.P อยู่ที่ 104,642.8 USDT ค่ะ โดยมี Previous Weekly High (PWH) อยู่ที่ 104,967.8 Previous Weekly Low (PWL) ที่ 93,338 ค่ะ

✨ ภาพรวมตลาดวันนี้ ✨

จากการวิเคราะห์ด้วยเครื่องมือคู่ใจของเรา ทั้ง SMC/ICT (Demand/Supply Zone, Order Block, Liquidity), EMA 50/200, Trend Strength, Money Flow, Chart/Price Pattern, Premium/Discount Zone, Trend line, Fibonacci, Elliott Wave และ Dow Theory ใน Timeframe ตั้งแต่ 15m ไปจนถึง Week! 📊 เราพบว่าภาพใหญ่ของ BTCUSDT.P ยังคงอยู่ในแนวโน้มขาขึ้นที่แข็งแกร่งมากๆ ค่ะ 👍 โดยเฉพาะใน Timeframe Day และ Week ที่สัญญาณทุกอย่างสนับสนุนทิศทางขาขึ้นอย่างชัดเจน Money Flow ยังไหลเข้าอย่างต่อเนื่อง และเราเห็นโครงสร้างตลาดแบบ Dow Theory ที่ยก High ยก Low ขึ้นไปเรื่อยๆ ค่ะ

อย่างไรก็ตาม... ใน Timeframe สั้นๆ อย่าง 15m และ 1H เริ่มเห็นสัญญาณของการชะลอตัวและการพักฐานบ้างแล้วค่ะ 📉 อาจมีการสร้าง Buyside และ Sellside Liquidity รอให้ราคาไปกวาดก่อนที่จะเลือกทางใดทางหนึ่ง ซึ่งเป็นเรื่องปกติของการเดินทางของ Smart Money ค่ะ

⚡ เปรียบเทียบแนวโน้มแต่ละ Timeframe ⚡

🪙 แนวโน้มตรงกัน Timeframe 4H, Day, Week ส่วนใหญ่ชี้ไปทาง "ขาขึ้น" ค่ะ ทุกเครื่องมือสนับสนุนแนวโน้มนี้อย่างแข็งแกร่ง 💪 เป้าหมายต่อไปคือการไปทดสอบ PWH และ High เดิม เพื่อสร้าง All-Time High ใหม่ค่ะ! 🪙 แนวโน้มต่างกัน Timeframe 15m, 1H ยังค่อนข้าง "Sideways" หรือ "Sideways Down เล็กน้อย" ค่ะ มีการบีบตัวของราคาและอาจมีการพักฐานสั้นๆ ซึ่งเป็นโอกาสในการหาจังหวะเข้า Long ที่ราคาดีขึ้นค่ะ

💡 วิธีคิดแบบ Market Slayer 💡

เมื่อแนวโน้มใหญ่เป็นขาขึ้นที่แข็งแกร่ง เราจะเน้นหาจังหวะเข้า Long เป็นหลักค่ะ การย่อตัวลงมาในระยะสั้นคือโอกาสของเราในการเก็บของ! 🛍️ เราจะใช้หลักการ SMC/ICT หาโซน Demand หรือ Order Block ที่ Smart Money อาจจะเข้ามาดันราคาขึ้น และรอสัญญาณ Price Action ยืนยันการกลับตัวค่ะ

สรุปแนวโน้มวันนี้:

🪙 ระยะสั้น: Sideways to Sideways Down (โอกาส 55%) ↔️↘️ 🪙 ระยะกลาง: ขาขึ้น (โอกาส 70%) ↗️ 🪙 ระยะยาว: ขาขึ้น (โอกาส 85%) 🚀 🪙 วันนี้: มีโอกาสย่อตัวเล็กน้อยก่อนจะมีแรงซื้อกลับเข้ามาเพื่อไปทดสอบ PWH (โอกาส Sideways Down เล็กน้อย สลับกับ Sideways Up: 60%) 🎢

I have been really busy this week with work - albeit back in Madeira - so I had little time to read or do much other than work. In the coming weeks I should have more time - I am taking a few weeks off work and have quite a list of things to do.

First thing is to relax a bit and enjoy the pleasant weather here in Funchal for a few days. With 1st May tomorrow it does seem that there will be quite a bit to do..

Some food for thought for you. Who takes and makes your decisions? Do you make them yourself based on information that you have and know to be true or do you allow other people to take and make decisions for you? For example - do you allow governments or unaccountable beaureaucrats and others to decide for you and even to compell you?

In theory Governments should respect Consent of the Governed and the 1948 Universal Declaration of Human Rights states that "The will of the people shall be the basis of the authority of government". For you to decide if and to what extent governments today are acting in line with these principles. If not, what can you do about it? I dive into this below and do refer back to letter 9 - section: So What can you do about it.

First, a few things to read, watch and listen to

• I Finance the Current Thing by Allen Farrington - when money is political, everything is political...

• Prediction for 2030 (the Great Reset). Sorelle explains things pretty clearly if you care to watch and listen...

• The Global Pandemic Treaty: What You Need to Know . James Corbett is pretty clear too... is this being done with your support? Did you miss something?

• Why the Past 10 Years of American Life Have Been Uniquely Stupid - fascinating thinking on how quite a few recent things came about...

And a few classics - you ought to know these already and the important messages in them should be much more obvious now...

• 1984 by George Orwell - look for the perpetual war & conflict, ubiquitous surveillance and censorship not to mention Room 101

• Animal farm - also by George Orwell - note how the pigs end up living in the farmhouse exceeding all the worst behaviour of the farmer and how the constitution on the wall changes. Things did not end well for loyal Boxer.

• Brave New World by Aldous Huxley- A World State, inhabited by genetically modified citizens and an intelligence-based social hierarchy - the novel anticipates large scale psychological manipulation and classical conditioning that are combined to make a dystopian society which is challenged by only a single individual who does not take the Soma.

The 7 Habits of Highly Effective People

One of the most transformative books that I ever read was 7 Habits of Highly Effective People by Steven Covey. Over many years and from researching hstorical literature he found seven traits that successful people typically display. By default everyone does the opposite of each of these! Check how you do - be honest...

• Habits 1-3 are habits of Self - they determine how you behave and feel

• Habits 4-6 are habits of interpersonal behaviour - they determine how you deal with and interact with others

• Habit 7 is about regeneration and self care - foundation for happy and healthy life and success

One: Be proactive

Choose your responses to all situations and provocations - your reaction to a situation determines how you feel about it.

By default people will be reactive and this controls their emotions

Two: Begin with the end in mind

When you start to work on something, have a clear view of the goal to be achieved; it should be something substantial that you need and will value.

By default people will begin with what is in front of them or work on details that they can do or progress without having a clear view on the end result to be achieved

Three: Put First things First

Be clear on, and begin with, the Big Rocks- the most important things. If you do not put the Big Rocks into your planning daily activities, your days will be full of sand and gravel! All things can be categorised as Urgent or Not-Urgent and Important or Not-Important.

By Default people will focus on Urgent regardless of importance - all of the results come from focusing on Important Non-Urgent things. All of the 7 Habits are in this category!

Four: Seek Win-Win in all dealings with people and in all negotiations

This is the only sustainable outcome; if you cannot achieve Win-Win then no-deal is the sustainable alternative.

By default people will seek Win-Loose - this leads to failed relationships

Five: Seek first to understand - only then to be understood.

Once you visibly understand the needs and expectations of your counterpart they will be open to listening to your point of view and suggestions/requests - not before!

By default people will expound their point of view or desired result causing their counterpart to want to do the same - this ends in "the dialogue of the deaf"

Six: Synergise - Seek the 3rd alternative in all problems and challenges

Work together to find a proposal that is better than what each of you had in mind

By default people will focus on their own desired results and items, regardless of what the other party could bring to help/facilitate or make available

Seven: Sharpen the saw

Take time to re-invigorate and to be healthy - do nothing to excess. Do not be the forrester who persists in cutting the tree with a blunt saw bcause sharpening it is inconvenient or would "take too much time"!

By default people tend to persist on activities and avoid taking time to reflect, prepare and recover

I. Historical Foundations of U.S. Monetary Architecture

The early monetary system of the United States was built atop inherited commodity money conventions from Europe’s maritime economies. Silver and gold coins—primarily Spanish pieces of eight, Dutch guilders, and other foreign specie—formed the basis of colonial commerce. These units were already integrated into international trade and piracy networks and functioned with natural compatibility across England, France, Spain, and Denmark. Lacking a centralized mint or formal currency, the U.S. adopted these forms de facto.

As security risks and the practical constraints of physical coinage mounted, banks emerged to warehouse specie and issue redeemable certificates. These certificates evolved into fiduciary media—claims on specie not actually in hand. Banks observed over time that substantial portions of reserves remained unclaimed for years. This enabled fractional reserve banking: issuing more claims than reserves held, so long as redemption demand stayed low. The practice was inherently unstable, prone to panics and bank runs, prompting eventual centralization through the formation of the Federal Reserve in 1913.

Following the Civil War and unstable reinstatements of gold convertibility, the U.S. sought global monetary stability. After World War II, the Bretton Woods system formalized the U.S. dollar as the global reserve currency. The dollar was nominally backed by gold, but most international dollars were held offshore and recycled into U.S. Treasuries. The Nixon Shock of 1971 eliminated the gold peg, converting the dollar into pure fiat. Yet offshore dollar demand remained, sustained by oil trade mandates and the unique role of Treasuries as global reserve assets.

II. The Structure of Fiduciary Media and Treasury Demand

Under this system, foreign trade surpluses with the U.S. generate excess dollars. These surplus dollars are parked in U.S. Treasuries, thereby recycling trade imbalances into U.S. fiscal liquidity. While technically loans to the U.S. government, these purchases act like interest-only transfers—governments receive yield, and the U.S. receives spendable liquidity without principal repayment due in the short term. Debt is perpetually rolled over, rarely extinguished.

This creates an illusion of global subsidy: U.S. deficits are financed via foreign capital inflows that, in practice, function more like financial tribute systems than conventional debt markets. The underlying asset—U.S. Treasury debt—functions as the base reserve asset of the dollar system, replacing gold in post-Bretton Woods monetary logic.

III. Emergence of Tether and the Parastatal Dollar

Tether (USDT), as a private issuer of dollar-denominated tokens, mimics key central bank behaviors while operating outside the regulatory perimeter. It mints tokens allegedly backed 1:1 by U.S. dollars or dollar-denominated securities (mostly Treasuries). These tokens circulate globally, often in jurisdictions with limited banking access, and increasingly serve as synthetic dollar substitutes.

If USDT gains dominance as the preferred medium of exchange—due to technological advantages, speed, programmability, or access—it displaces Federal Reserve Notes (FRNs) not through devaluation, but through functional obsolescence. Gresham’s Law inverts: good money (more liquid, programmable, globally transferable USDT) displaces bad (FRNs) even if both maintain a nominal 1:1 parity.

Over time, this preference translates to a systemic demand shift. Actors increasingly use Tether instead of FRNs, especially in global commerce, digital marketplaces, or decentralized finance. Tether tokens effectively become shadow base money.

IV. Interaction with Commercial Banking and Redemption Mechanics

Under traditional fractional reserve systems, commercial banks issue loans denominated in U.S. dollars, expanding the money supply. When borrowers repay loans, this destroys the created dollars and contracts monetary elasticity. If borrowers repay in USDT instead of FRNs:

• Banks receive a non-Fed liability (USDT).
• USDT is not recognized as reserve-eligible within the Federal Reserve System.
• Banks must either redeem USDT for FRNs, or demand par-value conversion from Tether to settle reserve requirements and balance their books.

This places redemption pressure on Tether and threatens its 1:1 peg under stress. If redemption latency, friction, or cost arises, USDT’s equivalence to FRNs is compromised. Conversely, if banks are permitted or compelled to hold USDT as reserve or regulatory capital, Tether becomes a de facto reserve issuer.

In this scenario, banks may begin demanding loans in USDT, mirroring borrower behavior. For this to occur sustainably, banks must secure Tether liquidity. This creates two options: - Purchase USDT from Tether or on the secondary market, collateralized by existing fiat. - Borrow USDT directly from Tether, using bank-issued debt as collateral.

The latter mirrors Federal Reserve discount window operations. Tether becomes a lender of first resort, providing monetary elasticity to the banking system by creating new tokens against promissory assets—exactly how central banks function.

V. Structural Consequences: Parallel Central Banking

If Tether begins lending to commercial banks, issuing tokens backed by bank notes or collateralized debt obligations: - Tether controls the expansion of broad money through credit issuance. - Its balance sheet mimics a central bank, with Treasuries and bank debt as assets and tokens as liabilities. - It intermediates between sovereign debt and global liquidity demand, replacing the Federal Reserve’s open market operations with its own issuance-redemption cycles.

Simultaneously, if Tether purchases U.S. Treasuries with FRNs received through token issuance, it: - Supplies the Treasury with new liquidity (via bond purchases). - Collects yield on government debt. - Issues a parallel form of U.S. dollars that never require redemption—an interest-only loan to the U.S. government from a non-sovereign entity.

In this context, Tether performs monetary functions of both a central bank and a sovereign wealth fund, without political accountability or regulatory transparency.

VI. Endgame: Institutional Inversion and Fed Redundancy

This paradigm represents an institutional inversion:

• The Federal Reserve becomes a legacy issuer.
• Tether becomes the operational base money provider in both retail and interbank contexts.
• Treasuries remain the foundational reserve asset, but access to them is mediated by a private intermediary.
• The dollar persists, but its issuer changes. The State becomes a fiscal agent of a decentralized financial ecosystem, not its monetary sovereign.

Unless the Federal Reserve reasserts control—either by absorbing Tether, outlawing its instruments, or integrating its tokens into the reserve framework—it risks becoming irrelevant in the daily function of money.

Tether, in this configuration, is no longer a derivative of the dollar—it is the dollar, just one level removed from sovereign control. The future of monetary sovereignty under such a regime is post-national and platform-mediated.

\> “Huge swathes of people…spend their entire working lives performing tasks they secretly believe do not really need to be performed.”\ \> — David Graeber, Bullshit Jobs

\> “We are in a system that must grow — forever — or it collapses. But technology, by its very nature, is deflationary.”\ \> — Jeff Booth, The Price of Tomorrow

We live in a strange paradox: Technological progress is supposed to make life easier, yet many people feel more overworked and less fulfilled than ever. While artificial intelligence and automation promise unprecedented productivity, it’s not yet clear whether that will mean fewer bullshit jobs — or simply new kinds of them.

What Is a Bullshit Job?

In his landmark book Bullshit Jobs, the late anthropologist David Graeber exposed a haunting truth: millions of jobs exist not because they are needed, but because of economic, political, or psychological inertia. These are roles that even the workers themselves suspect are meaningless — created to serve appearances, maintain hierarchies, or justify budgets.

Think:

• Middle managers approving other middle managers' reports

• Employees running meetings to prepare for other meetings

• Corporate roles invented to interface with poorly implemented AI tools

Bullshit work isn’t the absence of technology. It’s often the outcome of resisting what technology could actually do — in order to preserve jobs, status, or growth targets.

Booth’s Warning: The System is Rigged Against Deflation

In The Price of Tomorrow, entrepreneur Jeff Booth argues that the natural state of a tech-driven economy is deflation — things getting better, cheaper, and faster.

But our global financial system is built on perpetual inflation and debt expansion. Booth writes:

\> “We are using inflationary monetary policy to fight deflationary technological forces.”

Even as AI and automation could eliminate unnecessary jobs and increase abundance, our system requires jobs — or the illusion of them — to keep the economy expanding. So bullshit jobs persist, and even evolve.

AI as a Deflationary Force

AI is rapidly accelerating the deflation Booth described:

• Tasks that used to take hours now take seconds

• Whole creative and administrative processes are being streamlined

• Labor can scale digitally — one tool used globally at near-zero marginal cost

Embraced honestly, this could mean fewer hours, lower costs, and more prosperity. But again, we are not optimized for truth — we are optimized for GDP growth.

So we invent new layers of AI-enhanced bullshit:

• Prompt engineers writing prompts for other prompt engineers

• "Human-in-the-loop" validators reviewing AI output they don’t understand

• Consultants building dashboards that nobody reads

Toward a Post-Bullshit Future

Here’s the real opportunity: If we embrace deflation as a blessing — not a threat — and redesign our systems around truth, efficiency, and abundance, we could:

• Eliminate meaningless labor

• Reduce the cost of living dramatically

• Liberate people to create, heal, build, and rest

This means more than economic reform — it’s a philosophical shift. We must stop equating “employment” with value. That’s where Bitcoin and open-source tools point: toward a world where permissionless value creation is possible without the bloat of gatekeeping institutions.

Final Thought: Tech Won’t Save Us, But Truth Might

Technology, left to its own logic, tends toward freedom, efficiency, and abundance. But our current systems suppress that logic in favor of growth at all costs — even if it means assigning millions of people to do work that doesn’t need doing.

So will AI eliminate bullshit jobs?

It can. But only if we stop pretending we need them.

And for those of us who step outside the wage-work loop, something remarkable happens. We begin using these tools to create actual value — not to impress a boss, but to solve real problems and serve real people.

Recently, I built a tool using AI and automation that helps me cross-post content from Nostr to LinkedIn, Facebook, and X. It wasn’t for a paycheck. It was about leverage — freeing time, expanding reach, and creating a public record of ideas.\ You can check it out here:\ 👉 <https://tinyurl.com/ywxuowl5>

Will it help others? I don’t know yet.\ But it helped me — and that’s the point.

Real value creation doesn’t always begin with a business plan. Sometimes it starts with curiosity, conviction, and the courage to build without permission.

Maybe the future of work isn’t about scaling jobs at all.\ Maybe it’s about reclaiming time — and using these tools to build lives of meaning.

---

If this resonates — or if you’ve found your own way to reclaim time and create value outside the wage loop — zap me and share your story. Let’s build the post-bullshit economy together. ⚡

Prelude

I wrote this post differently than any of my others. It started with a discussion with AI on an OPSec-inspired review of separation of powers, and evolved into quite an exciting debate! I asked Grok to write up a summary in my overall writing style, which it got pretty well. I've decided to post it exactly as-is. Ultimately, I think there are two solid ideas driving my stance here:

1. Perfect is the enemy of the good
2. Failure is the crucible of success

Beyond that, just some hard-core belief in freedom, separation of powers, and operating from self-interest.

Intro

Alright, buckle up. I’ve been chewing on this idea for a while, and it’s time to spit it out. Let’s look at the U.S. government like I’d look at a codebase under a cybersecurity audit—OPSEC style, no fluff. Forget the endless debates about what politicians should do. That’s noise. I want to talk about what they can do, the raw powers baked into the system, and why we should stop pretending those powers are sacred. If there’s a hole, either patch it or exploit it. No half-measures. And yeah, I’m okay if the whole thing crashes a bit—failure’s a feature, not a bug.

The Filibuster: A Security Rule with No Teeth

You ever see a firewall rule that’s more theater than protection? That’s the Senate filibuster. Everyone acts like it’s this untouchable guardian of democracy, but here’s the deal: a simple majority can torch it any day. It’s not a law; it’s a Senate preference, like choosing tabs over spaces. When people call killing it the “nuclear option,” I roll my eyes. Nuclear? It’s a button labeled “press me.” If a party wants it gone, they’ll do it. So why the dance?

I say stop playing games. Get rid of the filibuster. If you’re one of those folks who thinks it’s the only thing saving us from tyranny, fine—push for a constitutional amendment to lock it in. That’s a real patch, not a Post-it note. Until then, it’s just a vulnerability begging to be exploited. Every time a party threatens to nuke it, they’re admitting it’s not essential. So let’s stop pretending and move on.

Supreme Court Packing: Because Nine’s Just a Number

Here’s another fun one: the Supreme Court. Nine justices, right? Sounds official. Except it’s not. The Constitution doesn’t say nine—it’s silent on the number. Congress could pass a law tomorrow to make it 15, 20, or 42 (hitchhiker’s reference, anyone?). Packing the court is always on the table, and both sides know it. It’s like a root exploit just sitting there, waiting for someone to log in.

So why not call the bluff? If you’re in power—say, Trump’s back in the game—say, “I’m packing the court unless we amend the Constitution to fix it at nine.” Force the issue. No more shadowboxing. And honestly? The court’s got way too much power anyway. It’s not supposed to be a super-legislature, but here we are, with justices’ ideologies driving the bus. That’s a bug, not a feature. If the court weren’t such a kingmaker, packing it wouldn’t even matter. Maybe we should be talking about clipping its wings instead of just its size.

The Executive Should Go Full Klingon

Let’s talk presidents. I’m not saying they should wear Klingon armor and start shouting “Qapla’!”—though, let’s be real, that’d be awesome. I’m saying the executive should use every scrap of power the Constitution hands them. Enforce the laws you agree with, sideline the ones you don’t. If Congress doesn’t like it, they’ve got tools: pass new laws, override vetoes, or—here’s the big one—cut the budget. That’s not chaos; that’s the system working as designed.

Right now, the real problem isn’t the president overreaching; it’s the bureaucracy. It’s like a daemon running in the background, eating CPU and ignoring the user. The president’s supposed to be the one steering, but the administrative state’s got its own agenda. Let the executive flex, push the limits, and force Congress to check it. Norms? Pfft. The Constitution’s the spec sheet—stick to it.

Let the System Crash

Here’s where I get a little spicy: I’m totally fine if the government grinds to a halt. Deadlock isn’t a disaster; it’s a feature. If the branches can’t agree, let the president veto, let Congress starve the budget, let enforcement stall. Don’t tell me about “essential services.” Nothing’s so critical it can’t take a breather. Shutdowns force everyone to the table—debate, compromise, or expose who’s dropping the ball. If the public loses trust? Good. They’ll vote out the clowns or live with the circus they elected.

Think of it like a server crash. Sometimes you need a hard reboot to clear the cruft. If voters keep picking the same bad admins, well, the country gets what it deserves. Failure’s the best teacher—way better than limping along on autopilot.

States Are the Real MVPs

If the feds fumble, states step up. Right now, states act like junior devs waiting for the lead engineer to sign off. Why? Federal money. It’s a leash, and it’s tight. Cut that cash, and states will remember they’re autonomous. Some will shine, others will tank—looking at you, California. And I’m okay with that. Let people flee to better-run states. No bailouts, no excuses. States are like competing startups: the good ones thrive, the bad ones pivot or die.

Could it get uneven? Sure. Some states might turn into sci-fi utopias while others look like a post-apocalyptic vidya game. That’s the point—competition sorts it out. Citizens can move, markets adjust, and failure’s a signal to fix your act.

Chaos Isn’t the Enemy

Yeah, this sounds messy. States ignoring federal law, external threats poking at our seams, maybe even a constitutional crisis. I’m not scared. The Supreme Court’s there to referee interstate fights, and Congress sets the rules for state-to-state play. But if it all falls apart? Still cool. States can sort it without a babysitter—it’ll be ugly, but freedom’s worth it. External enemies? They’ll either unify us or break us. If we can’t rally, we don’t deserve the win.

Centralizing power to avoid this is like rewriting your app in a single thread to prevent race conditions—sure, it’s simpler, but you’re begging for a deadlock. Decentralized chaos lets states experiment, lets people escape, lets markets breathe. States competing to cut regulations to attract businesses? That’s a race to the bottom for red tape, but a race to the top for innovation—workers might gripe, but they’ll push back, and the tension’s healthy. Bring it—let the cage match play out. The Constitution’s checks are enough if we stop coddling the system.

Why This Matters

I’m not pitching a utopia. I’m pitching a stress test. The U.S. isn’t a fragile porcelain doll; it’s a rugged piece of hardware built to take some hits. Let it fail a little—filibuster, court, feds, whatever. Patch the holes with amendments if you want, or lean into the grind. Either way, stop fearing the crash. It’s how we debug the republic.

So, what’s your take? Ready to let the system rumble, or got a better way to secure the code? Hit me up—I’m all ears.

@ 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?

The promise of AI is intoxicating: slash operational costs by 50-80%, achieve software-style margins on service businesses and and watch enterprise value multiply overnight.

But this initial value creation contains a hidden trap that could leave businesses worth less than when they started. Understanding the "Value Trap" is key to navigating a transition to an AI economy.

What is the Value Trap?

Whilst the value trap is forward looking and somewhat theoretical at this point, there are strong financial incentives to drive investments (many $bns of are looking at the transformation opportunity) that mean this should be taken very seriously.

The Value Trap unfolds in distinct phases:

Phase 1: Status Quo A typical service business operates with 100 units of revenue and 90 units of cost, generating 10 units of profit, representing a standard 10% margin. A bog standard business we can all relate to, long term customers locked in, market fit a distant memory, but growth is hard at this point.

Phase 2: Cost Reduction Early AI adopters slash operational expenses from 90 to 20 units while maintaining 100 units of revenue. This is the very real promise when moving to a "Human at the Edge" model that we'll unpack in a future article. Suddenly, they're generating 80 units of profit at an 8x increase that can easily add multiple to the enterprise value! A venture style return on a business previously struggling for growth.

Phase 3: Growth Phase With massive profit margins comes pricing power. These businesses can undercut competitors while maintaining healthy margins, driving rapid revenue growth. Having removed the human constraint on scaling and the additional overheads and complexity this introduces we see seemingly unlimited expansion. The brakes are truly off at this point for early adopters to expand total market share.

Phase 4: Competition Emerges The extraordinary returns attract competitors. It's important to note there is no technical moat here, other businesses implement similar AI strategies, often from your own staff who may have been let go, new entrants launch AI-native operations, and pricing power erodes.

Phase 5: Mean Reversion After 3-7 years (our best guess given current investment interest in transformation led PE), competitive pressure drives revenue down from 100 to 25 units while costs remain at 20. The business ends up with similar margins to where it started but at much lower absolute revenue, potentially destroying enterprise value.

What you've done is just massively reduced costs in this industry by displacing jobs and those individuals can turn around and compete. You incentivise the competition which erodes your pricing power

Why This Pattern is Inevitable

The Value Trap isn't pure speculation, but based on market dynamics playing out given a set of financial incentives. We believe there are several key forces that make this cycle almost guaranteed:

The Arbitrage is Too Attractive When businesses can achieve "venture returns with no product-market fit risk," capital will flood in. Private equity and Venture Capital firms are already raising funds specifically to acquire traditional service businesses and apply AI transformation strategies .

Low Technical Barriers Unlike previous technological advantages, AI implementation doesn't require significant technical moats. Much of the technology is open source, and the real barrier is process redesign thinking rather than proprietary technology.

The "One Player" Principle In any market, it only takes one competitor to implement AI-native processes to force everyone else to adapt. You either "play the game or you get left behind".

Capital Abundance With global money supply expanding and traditional investment opportunities yielding lower returns, the combination of proven product-market fit and dramatic cost reduction potential represents an irresistible opportunity for investors.

Strategic Response for SMEs: The Netflix Model

Small and medium enterprises actually have a significant advantage in navigating the Value Trap, but they need to act strategically and start moving now.

Embrace the Incubation Approach Rather than gutting your existing business, adopt Netflix's strategy: build an AI-native version of your business alongside your current operations. This approach manages risk while positioning for the future.

The answer here is why not both. you don't necessarily have to gut your current business, but you should be thinking about what does my business look like in five years and how do I transition into that.

Leverage Your Natural Advantages Small businesses can adapt faster than large enterprises. While a 20,000-person company faces "political shockwaves" when reducing workforce, a 10-person business can double revenue without anyone noticing. You can focus on growth rather than painful cost-cutting.

Remove Growth Constraints Early AI removes the traditional constraint where "adding the next person" represents a significant capital investment. Small businesses can scale efficiently once they've redesigned their processes around AI-native workflows, avoid further capital outlay and scaling without increasing complexity in operations.

Focus on Local Networks For various reasons associated with the commoditisation of intelligence, we believe the future favours "hyper-localised" businesses serving customers who "know, like, and trust" them. As intelligence becomes commoditised, human relationships become more valuable, not less.

Strategic Response for Capital Allocators

For private equity and venture capital firms, the Value Trap presents both enormous opportunity and significant risk.

Target the Right Businesses Look for businesses with strong persistent moats that will slow mean reversion:

• Strong brand and customer relationships

• High customer acquisition costs in the industry

• Regulatory barriers to entry

• Capital-intensive startup requirements

• Long-term contracts and switching costs

Master the Timing The key is capturing value during the expansion phase and exiting before mean reversion accelerates, or finding an appropriate time arbitrage solution to retain value (see below). The optimal point if you're a capital allocator is almost when you've extracted the most cost out of the business.

Consider Hybrid Strategies Rather than just gutting existing businesses, consider acquiring for distribution and customer base while building AI-native operations alongside traditional ones. This provides multiple exit strategies and reduces execution risk.

Bitcoin: The Time Arbitrage Solution

Whenever I've talked to anybody about AI, my first point of advice is just buy bitcoin.

This isn't just evangelism, so much as a recognition of where you would want to hold value as the Value Trap plays out. In essence the value trap generates an arbitrage opportunity, hige profits are pulled forwards short-term balooning the balance sheet, but the second order consequences of this change risk destroying the value you just created!

We believe alongside rapid competition leading to price for services collapsing, the mass job displacement leads to political pressure for intervention.

This could take several forms, but UBI, mortgage bailouts, unemployment extensions, seizure of existing property.

"All roads lead to money printing," as Pete notes in Good Stuff 02 .

During Weimar Republic hyperinflation, "the cost of a newspaper in year five was the same nominal figure as all of the money that existed in year four." While extreme, this illustrates how quickly monetary systems can shift as inflation and money supply inflation begins to run.

To resolve these issues, Bitcoin allows you to conduct arbitrage across time in an asset that is inflation resistant (fixed supply), hard to seize, has no counter party risk (if someone holds your gold, stocks, cash they can take it without asking) and transportable. Capturing value today and preserving it through monetary system changes protecting against the second and third-order effects of massive economic disruption, that AI represents.

Opportunity, Not Fear: The Renaissance Ahead

The Value Trap isn't a reason to avoid AI, it's a roadmap for navigating inevitable change strategically.

The Entrepreneurial Renaissance This could be a Renaissance for entrepreneurs, if you're entrepreneurial minded, this is an amazing time to be alive because there's opportunity that exists in all fields and the barriers to entry have never been lower.

Liberation from Busy Work The displacement of administrative and routine cognitive work frees humans for higher-value creation.

Democratisation of Intelligence When you can "purchase intelligence in buckets of $0.02 API calls," the barriers to starting and scaling businesses collapse. Individual entrepreneurs can build businesses that previously required large teams, with much lower complexity and risk.

Cost Reduction Benefits Everyone The ultimate outcome of the Value Trap cycle benefits consumers through dramatically lower prices for goods and services.

"Who doesn't want cheaper stuff? Why don't we just reduce the cost of everything massively?"

Conclusion: Embrace the High Agency Era

The Value Trap represents a fundamental shift from employment-based to entrepreneurship-based wealth creation. Rather than fearing job displacement, we should prepare for "the age of the entrepreneur" a high agency era.

The businesses and individuals who thrive will be those who:

• Understand the cycle and position accordingly

• Focus on unique value creation rather than routine processing or middleman models

• Build local networks and relationships

• Preserve wealth through the monetary transition

• Embrace building and creating unique value

If you are high agency, you can make anything happen.

The Value Trap isn't just about AI transforming business, it won't do this on its own, its a description of how humans will use this technology to generate and capture value.

The future belongs to builders, creators, and entrepreneurs who can navigate transition periods and emerge stronger. The Value Trap is the map, use it wisely.

This article draws heavily on discussion between myself and business partner Andy in Episode 02 of The Good Stuff, if you prefer listening try that :)

Earlier this year I launched the asknostr.site project which has been a great journey and learning experience. I had wanted to write down my goals and ideas with the project but didn't get to it yet. Primal launching the article editor was a trigger for me to go for it.

Ever since I joined Nostr i was looking for ways to apply my skillset solve a problem and help with adoption. Around Christmas I figured that a Quora/Stackoverflow alternative is something that needs to exist on Nostr.

Before I knew it I had a pretty decent prototype. And because the network already had so much awesome content, contributors and authors I was never discouraged by the challenge that kills so many good ideas -> "Where do I get the first users?".

Since the initial announcement I have received so much encouragement through zaps, likes, DM's, and maybe most of all seeing the increase in usage of the site and #asknostr content kept me going.

Current State

The current version of the site is stable and most bugs are hashed out. After logging in (remote signer, extension or nsec) you can engage with content through votes, comments and replies. Or simply ask a new question.

All content is stored in the site's own private relay and preprocessed/computed into a single data store (postgres) so the site is fast, accessible and crawl-able.

The site supports browsing hashtags, voting/commenting on answers, asking new questions and every contributor get their own profile (example). At the time of writing the site has 41k questions, almost 200k replies/comments and upwards of 5 million sats purely for #asknostr content.

What to expect/On my list

There are plenty of things and UI bugs that need love and between writing the draft of this post and hitting publish I shipped 3 minor bug fixes. Little by little, bit by bit...

In addition to all those small details here is an overview of the things on my own wish list:

• Inline Zaps: Ability to zap from the asknostr.site interface. Click the zap button, specify or pick the number of sats zap away.

• Contributor Rank: A leaderboard to add some gamification. More recognition to those nostriches that spend their time helping other people out

• Search by Keyword: Search all content by keywords. Experiment with the index to show related questions or answers

• Better User Profiles: Improve the user profile so it shows all the profile questions and answers. Quick buttons to follow or zap that person. Better insights in the topics (hashtags) the profile contributes to

• Bookmarks: Ability to bookmark questions and answers. Increase bookmark weight as a signal to rank answers.

• Smarter Scoring: Tune how answers are scored (winning answer formula). Perhaps give more weight to the question author or use WoT. Not sure yet.

All of this is happening at some point so follow me if you want to stay up to date.

Goals

To manage expectations and keep me focussed I write down the mid and long term goals of the project.

Long term

Call me cheesy but I believe that humanity will flourish through an open web and sound money. My own journey started from with bitcoin but if you asked me today if it's BTC or nostr that is going to have the most impact I wouldn't know what to answer. Chicken or egg?

The goal of the project is to offer an open platform that empowers individuals to ask questions, share expertise and access high-quality information across different topics. The project empowers anyone to monetize their experience creating a sustainable ecosystem that values and rewards knowledge sharing. This will ultimately democratize access to knowledge for all.

Mid term

The project can help a lot with onboarding new users onto the network. Once we start to rank on certain topics we can get a piece of the search traffic pie (StackOverflows 12 million, and Quora 150 million visitors per month) which is a great way to expose people to the power of the network.

First time visitors do not need to know about nostr or zaps to receive value. They can browse around, discover interesting content and perhaps even create a profile without even knowing they are on Nostr now.

Gradually those users will understand the value of the network through better rankings (zaps beats likes), a cross-client experience and a profile that can be used on any nostr site or app.

In order for the site to do that we need to make sure content is browsable by language, (sub)topics and and we double down on 'the human touch' with real contributors and not LLMs.

Short Term Goal

The first goal is to make the site really good and an important resource for existing Nostr users. Enable visitors to search and discover what they are interested in. Integrate within the existing nostr eco system with 'open in' functionality and quick links to interesting projects (followerpacks?)

One of things i want to get right is to improve user retention by making the whole Q\&A experience more sticky. I want to run some experiments (bots, award, summaries) to get more people to use asknostr.site more often and come back.

What about the name?

Finally the big question: What about the asknostr.site name? I don't like the name that much but it's what people know. I think there is a high chance that people will discover Nostr apps like Olas, Primal or Damus without needing to know what NOSTR is or means.

Therefore I think there is a good chance that the project won't be called asknostr.site forever. I guess it all depends on where we all take this.

Onwards!

This looks like a handy app for writing long form posts on Nostr. Giving it a test but wasn’t able to enable file saving, which might be because I’m using Chrome on the iPhone? Perhaps it needs to be done on my laptop instead?

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!

As a product builder over too many years to mention, I’ve lost count of the number of times I’ve seen promising ideas go from zero to hero in a few weeks, only to fizzle out within months.

The problem with most finance apps, however, is that they often become a reflection of the internal politics of the business rather than an experience solely designed around the customer. This means that the focus is on delivering as many features and functionalities as possible to satisfy the needs and desires of competing internal departments, rather than providing a clear value proposition that is focused on what the people out there in the real world want. As a result, these products can very easily bloat to become a mixed bag of confusing, unrelated and ultimately unlovable customer experiences—a feature salad, you might say.

Financial products, which is the field I work in, are no exception. With people’s real hard-earned money on the line, user expectations running high, and a crowded market, it’s tempting to throw as many features at the wall as possible and hope something sticks. But this approach is a recipe for disaster.

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.

Governments and the press often publish data on the population’s knowledge of Catalan. However, this data only represents one stage in the linguistic process and does not accurately reflect the state of the language, since a language only has a future if it is used. Knowledge is a necessary step toward using a language, but it is not the final stage — that stage is actual use.

So what is the state of Catalan usage? If we look at data on regular use, we see that the Catalan language has remained stagnant over the past hundred years, with nearly the same number of regular speakers. In 1930, there were around 2.5 million speakers, and in 2018, there were 2.7 million.

Regular use of Catalan in Catalonia, in millions of speakers. The dotted segments are an estimate of the trend, based on the statements of Joan Coromines and adjusted according to Catalonia’s population growth.

These figures wouldn’t necessarily be negative if the language’s integrity were strong, that is, if its existence weren’t threatened by other languages. But the population of Catalonia has grown from 2.7 million in 1930 to 7.5 million in 2018. This means that today, regular Catalan speakers make up only 36% of Catalonia’s population, whereas in 1930, they represented 90%.

Regular use of Catalan in Catalonia, as a percentage of speakers. The dotted segments are an estimate of the trend, based on the statements of Joan Coromines and adjusted according to Catalonia’s population growth.

The language that has gained the most ground is mainly Spanish, which went from 200,000 speakers in 1930 to 3.8 million in 2018. Moreover, speakers of other foreign languages (500,000 speakers) have also grown more than Catalan speakers over the past hundred years.

Notes, Sources, and Methodology

The data from 2003 onward is taken from Idescat (source). Before 2003, there are no official statistics, but we can make interpretations based on historical evidence. The data prior to 2003 is calculated based on two key pieces of evidence:

• 1st Interpretation: In 1930, 90% of the population of Catalonia spoke Catalan regularly. Source and evidence: The Romance linguist Joan Coromines i Vigneaux, a renowned 20th-century linguist, stated in his 1950 work "El que s'ha de saber de la llengua catalana" that "In this territory [Greater Catalonia], almost the entire population speaks Catalan as their usual language" (1, 2).\ While "almost the entire population" is not a precise number, we can interpret it quantitatively as somewhere between 80% and 100%. For the sake of a moderate estimate, we assume 90% of the population were regular Catalan speakers, with the remaining 10% being immigrants and officials of the Spanish state.

• 2nd Interpretation: Regarding population growth between 1930 and 1998, on average, 60% is due to immigration (mostly adopting or already using Spanish language), while 40% is natural growth (likely to acquire Catalan language from childhood). Source and evidence: Between 1999 and 2019, when more detailed data is available, immigration accounted for 68% of population growth. From 1930 to 1998, there was a comparable wave of migration, especially between 1953 and 1973, largely of Spanish-speaking origin (3, 4, 5, 6). To maintain a moderate estimate, we assume 60% of population growth during that period was due to immigration, with the ratio varying depending on whether the period experienced more or less total growth.

Per les xarxes socials es parla amb efusivitat de que Bitcoin arribarà a valer milions de dòlars. El mateix Hal Finney allà pel 2009, va estimar el potencial, en un cas extrem, de 10 milions $:

\> As an amusing thought experiment, imagine that Bitcoin is successful and becomes the dominant payment system in use throughout the world. Then the total value of the currency should be equal to the total value of all the wealth in the world. Current estimates of total worldwide household wealth that I have found range from $100 trillion to $300 trillion. Withn 20 million coins, that gives each coin a value of about $10 million. <https://satoshi.nakamotoinstitute.org/emails/bitcoin-list/threads/4/>

No estic d'acord amb els càlculs del bo d'en Hal, ja que no consider que la valoració d'una moneda funcioni així. En qualsevol cas, el 2009 la capitalització de la riquesa mundial era de 300 bilions $, avui és de 660 bilions $, és a dir ha anat pujant un 5,3% de manera anual, $$(660/300)^{1/15} = 1.053$$

La primera apreciació amb aquest augment anual del 5% és que si algú llegeix aquest article i té diners que no necessita aturats al banc (estalvis), ara és bon moment per començar a moure'ls, encara sigui amb moviments defensius (títols de deute governamental o la propietat del primer habitatge). La desagregació per actius dels 660 bilions és:

1. Immobiliari residencial = 260 bilions $

2. Títols de deute = 125 bilions $

3. Accions = 110 bilions

4. Diners fiat = 78 bilions $

5. Terres agrícoles = 35 bilions $

6. Immobiliari comercial = 32 bilions $

7. Or = 18 bilions $

8. Bitcoin = 2 bilions $

La riquesa mundial és major que 660 bilions, però aquests 8 actius crec que són els principals, ja que s'aprecien a dia d'avui. El PIB global anual és de 84 bilions $, que no són bromes, però aquest actius creats (cotxes, ordinadors, roba, aliments...), perden valor una vegada produïts, aproximant-se a 0 passades unes dècades.

Partint d'aquest nombres com a vàlids, la meva posició base respecte de Bitcoin, ja des de fa un parell d'anys, és que te capacitat per posar-se al nivell de capitalització de l'or, perquè conceptualment s'emulen bé, i perquè tot i que Bitcoin no té un valor tangible industrial com pot tenir l'or, sí que te un valor intangible tecnològic, que és pales en tot l'ecosistema que s'ha creat al seu voltant:

• Creació de tecnologies de pagament instantani: la Lightning Network, Cashu i la Liquid Network.

• Producció d'aplicacions amb l'íntegrament de pagaments instantanis. Especialment destacar el protocol de Nostr (Primal, Amethyst, Damus, Yakihonne, 0xChat...)

• Industria energètica: permet estabilitzar xarxes elèctriques i emprar energia malbaratada (flaring gas), amb la generació de demanda de hardware i software dedicat.

• Educació financera i defensa de drets humans. És una eina de defensa contra governs i estats repressius. La Human Rights Foundation fa una feina bastant destacada d'educació.

Ara posem el potencial en nombres:

• Si iguala l'empresa amb major capitalització, que és Apple, arribaria a uns 160 mil dòlars per bitcoin.

• Si iguala el nivell de l'or, arribaria a uns 800 mil dòlars per bitcoin.

• Si iguala el nivell del diner fiat líquid, arribaria a un 3.7 milions de dòlars per bitcoin.

Crec que igualar la capitalització d'Apple és probable en els pròxims 5 - 10 anys. També igualar el nivell de l'or en els pròxims 20 anys em sembla una fita possible. Ara bé, qualsevol fita per sota d'aquesta capitalització ha d'implicar tota una serie de successos al món que no sóc capaç d'imaginar. Que no vol dir que no pugui passar.

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.

https://simplex.chat/contact#/?v=2-4&smp=smp%3A%2F%2FSkIkI6EPd2D63F4xFKfHk7I1UGZVNn6k1QWZ5rcyr6w%3D%40smp9.simplex.im%2FbI99B3KuYduH8jDr9ZwyhcSxm2UuR7j0%23%2F%3Fv%3D1-2%26dh%3DMCowBQYDK2VuAyEAS9C-zPzqW41PKySfPCEizcXb1QCus6AyDkTTjfyMIRM%253D%26srv%3Djssqzccmrcws6bhmn77vgmhfjmhwlyr3u7puw4erkyoosywgl67slqqd.onion

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.

Before I saw those X right-wing political “influencers” parading their Epstein binders in that PR stunt, I’d already posted this on Nostr, an open protocol. 

“Today, the world’s attention will likely fixate on Epstein, governmental failures in addressing horrific abuse cases, and the influential figures who perpetrate such acts—yet few will center the victims and survivors in the conversation. The survivors of Epstein went to law enforcement and very little happened. The survivors tried to speak to the corporate press and the corporate press knowingly covered for him. In situations like these social media can serve as one of the only ways for a survivor’s voice to be heard. 

It’s becoming increasingly evident that the line between centralized corporate social media and the state is razor-thin, if it exists at all. Time and again, the state shields powerful abusers when it’s politically expedient to do so. In this climate, a survivor attempting to expose someone like Epstein on a corporate tech platform faces an uphill battle—there’s no assurance their voice would even break through. Their story wouldn’t truly belong to them; it’d be at the mercy of the platform, subject to deletion at a whim. Nostr, though, offers a lifeline—a censorship-resistant space where survivors can share their truths, no matter how untouchable the abuser might seem. A survivor could remain anonymous here if they took enough steps. 

Nostr holds real promise for amplifying survivor voices. And if you’re here daily, tossing out memes, take heart: you’re helping build a foundation for those who desperately need to be heard.“

That post is untouchable—no CEO, company, employee, or government can delete it. Even if I wanted to, I couldn’t take it down myself. The post will outlive me on the protocol. 

The cozy alliance between the state and corporate social media hit me hard during that right-wing X “influencer” PR stunt. Elon owns X. Elon’s a special government employee. X pays those influencers to post. We don’t know who else pays them to post. Those influencers are spurred on by both the government and X to manage the Epstein case narrative. It wasn’t survivors standing there, grinning for photos—it was paid influencers, gatekeepers orchestrating yet another chance to re-exploit the already exploited.

The bond between the state and corporate social media is tight. If the other Epsteins out there are ever to be unmasked, I wouldn’t bet on a survivor’s story staying safe with a corporate tech platform, the government, any social media influencer, or mainstream journalist. Right now, only a protocol can hand survivors the power to truly own their narrative.

I don’t have anything against Elon—I’ve actually been a big supporter. I’m just stating it as I see it. X isn’t censorship resistant and they have an algorithm that they choose not the user. Corporate tech platforms like X can be a better fit for some survivors. X has safety tools and content moderation, making it a solid option for certain individuals. Grok can be a big help for survivors looking for resources or support! As a survivor, you know what works best for you, and safety should always come first—keep that front and center.

That said, a protocol is a game-changer for cases where the powerful are likely to censor. During China's # MeToo movement, survivors faced heavy censorship on social media platforms like Weibo and WeChat, where posts about sexual harassment were quickly removed, and hashtags like # MeToo or "woyeshi" were blocked by government and platform filters. To bypass this, activists turned to blockchain technology encoding their stories—like Yue Xin’s open letter about a Peking University case—into transaction metadata. This made the information tamper-proof and publicly accessible, resisting censorship since blockchain data can’t be easily altered or deleted.

I posted this on X 2/28/25. I wanted to try my first long post on a nostr client. The Epstein cover up is ongoing so it’s still relevant, unfortunately.

Over the last decade, birth rates in Spain have dropped by 30%, from 486,000 births in 2010 to 339,000 in 2020, a decline only comparable to that seen in Japan and the Four Asian Tigers.

The main cause seems to stem from two major factors: (1) the widespread use of contraceptive methods, which allow for pregnancy control without reducing sexual activity, and (2) women's entry into the labor market, leading to a significant shift away from traditional maternal roles.

In this regard, there is a phenomenon of demographic inertia that I believe could become significant. When a society ages and the population pyramid inverts, the burden this places on the non-dependent population could further contribute to a deeper decline in birth rates.

The more resources (time and money) non-dependent individuals have to dedicate to the elderly (dependents), the less they can allocate to producing new births (also dependents):

• An only child who has to care for both parents will bear a burden of 2 (2 ÷ 1).
• Three siblings who share the responsibility of caring for their parents will bear a burden of 0.6 (2 ÷ 3).

This burden on only children could, in many cases, be significant enough to prevent them from having children of their own.

In Spain, the generation of only children reached reproductive age in 2019(*), this means that right now the majority of people in reproductive age in Spain are only child (or getting very close to it).

If this assumption is correct, and aging feeds on itself, then, given that Spain has one of the worst demographic imbalances in the world, this phenomenon is likely to manifest through worsening birth rates. Spain’s current birth rate of 1.1 may not yet have reached its lowest point.

(*)Birth rate table and the year in which each generation reaches 32 years of age, Spain.

| Year of birth | Birth rate | Year in which the generation turns 32 | | ------------------ | -------------- | ----------------------------------------- | | 1971 | 2.88 | 2003 | | 1972 | 2.85 | 2004 | | 1973 | 2.82 | 2005 | | 1974 | 2.81 | 2006 | | 1975 | 2.77 | 2007 | | 1976 | 2.77 | 2008 | | 1977 | 2.65 | 2009 | | 1978 | 2.54 | 2010 | | 1979 | 2.37 | 2011 | | 1980 | 2.21 | 2012 | | 1981 | 2.04 | 2013 | | 1982 | 1.94 | 2014 | | 1983 | 1.80 | 2015 | | 1984 | 1.72 | 2016 | | 1985 | 1.64 | 2017 | | 1986 | 1.55 | 2018 | | 1987 | 1.49 | 2019 | | 1988 | 1.45 | 2020 | | 1989 | 1.40 | 2021 | | 1990 | 1.36 | 2022 | | 1991 | 1.33 | 2023 | | 1992 | 1.31 | 2024 | | 1993 | 1.26 | 2025 | | 1994 | 1.19 | 2026 | | 1995 | 1.16 | 2027 | | 1996 | 1.14 | 2028 | | 1997 | 1.15 | 2029 | | 1998 | 1.13 | 2030 | | 1999 | 1.16 | 2031 | | 2000 | 1.21 | 2032 | | 2001 | 1.24 | 2033 | | 2002 | 1.25 | 2034 | | 2003 | 1.30 | 2035 | | 2004 | 1.32 | 2036 | | 2005 | 1.33 | 2037 | | 2006 | 1.36 | 2038 | | 2007 | 1.38 | 2039 | | 2008 | 1.44 | 2040 | | 2009 | 1.38 | 2041 | | 2010 | 1.37 | 2042 | | 2011 | 1.34 | 2043 | | 2012 | 1.32 | 2044 | | 2013 | 1.27 | 2045 | | 2014 | 1.32 | 2046 | | 2015 | 1.33 | 2047 | | 2016 | 1.34 | 2048 | | 2017 | 1.31 | 2049 | | 2018 | 1.26 | 2050 | | 2019 | 1.24 | 2051 | | 2020 | 1.19 | 2052 |

This past week I have been very busy in Holywood - just outside Belfast, Northern Ireland with a lot to do on top of my day-job! It was an unplanned trip but mission accomplished and we are off on the road again. I am writing this on my 3h30 Ryanair flight - so even in weeks like this you can find time to reflect quietly and think clearly if you look for it and seize the opportunity.

You might have noticed that I have "rebranded" the website and newsletter as "Letter From ...around the world". This reflects the reality that Hong Kong is not currently the "Asia World City" and I am not there. Whether it will ever reclaim that title again and when, or even if I can return remains to be seen. I am deeply saddened that after living 10 fabulous years in HK we had to abandon everything that Saturday night at the end of February.

This is the third time in my life that I have chosen Exit from "Loyalty, Voice or Exit" - (recall issue 09 - On Location).... Expect both Voice and Exit to become increasingly difficult or even unavailable in many jurisdictions. It is time to wake up. Talk to me if you are awake or curious!

One thing I learned back in 2004 on my first businss trip to New York is that "The way you react to a situation determines how you feel about it". This is one of so many insights that I learned from "The 7 Habits of Highly Effective People" by Steven Covey. I found the book at 4pm in the afternoon walking around outside my hotel trying to stay up to overcome jet-lag. I got back to the hotel and proceeded to devour the entire book overnight. I had never done that with any book before and I do not think I have done it since. Look out for a full review in an upcoming newsletter.

Thanks to Ali Abdaal for his passionate and insightful review of "Show Your Work" by Austin Kleon - clearly this is something that he has internalised and he does practice what he preaches. Indeed this is a short and easy read with many pictures and simple suggestions - recommended! I did read it on my Kindle and I am enjoying how the highlights automagically sync into Obsidian (see last week's find).

I was also inspired by Ali's How to Start a Youtube Channel explainer. I have been following Ali for about 5 years since he was a student doing these videos in his student room on his iPhone while studying Medicine in Cambridge. His passion for sharing his insights on how to study effectively as well as facilitating the learning that medical students needed to do enabled him to set up his own businesss. This set him on the road to his current 3 million subscribers and a business employing over a dozen people inspiring and helping others to acquire skills that are increasingly valuable in the the world today and going forward.

Over the coming months I will be experimenting with different channels and different media not only to discover new insights for myself but also to share things that I distill and find interesting. Also somewhat loosely inspired by "How to Get What you want and Want What You Have" by Jon Gray, I do recognize that I am now in the latter of the "Ten Time Periods" - if I had to pick one, I would say number 8 - at least that is how I feel!

So do subscribe to the newsletter and do follow along on Youtube. I'm obviously still in stage 1 of Ali's 3-stage process - so be patient and do give feedback, questions and suggestions!

Another day - another Airport...

That's it!

Deliberate (?) trade-offs we make for the sake of output speed.

... By sacrificing depth in my learning, I can produce substantially more work. I’m unsure if I’m at the correct balance between output quantity and depth of learning. This uncertainty is mainly fueled by a sense of urgency due to rapidly improving AI models. I don’t have time to learn everything deeply. I love learning, but given current trends, I want to maximize immediate output. I’m sacrificing some learning in classes for more time doing outside work. From a teacher’s perspective, this is obviously bad, but from my subjective standpoint, it’s unclear.

Finding the balance between learning and productivity. By trade, one cannot be productive in specific areas without first acquire the knowledge to define the processes needed to deliver. Designing the process often come on a try and fail dynamic that force us to learn from previous mistakes.

I found this little journal story fun but also little sad. Vincent's realization, one of us trading his learnings to be more productive, asking what is productivity without quality assurance?

Inevitably, parts of my brain will degenerate and fade away, so I need to consciously decide what I want to preserve or my entire brain will be gone. What skills am I NOT okay with offloading? What do I want to do myself?

At this point, we should be arresting, not firing, any FBI employee who delays, destroys, or withholds information on the Epstein case. There is ZERO explanation I will accept for redacting anything for “national security” reasons. A lot of Trump supporters are losing patience with Pam Bondi. I will give her the benefit of the doubt for now since the corruption within the whole security/intelligence apparatus of our country runs deep. However, let’s not forget that probably Trump’s biggest mistakes in his first term involved picking weak and easily corruptible (or blackmailable) officials. It seemed every month a formerly-loyal person did a complete 180 degree turn and did everything they could to screw him over, regardless of the betrayal’s effect on the country or whatever principles that person claimed to have. I think he’s fixed his screening process, but since we’re talking about the FBI, we know they have the power to dig up any dirt or blackmail material available, or just make it up. In the Epstein case, it’s probably better to go after Bondi than give up a treasure trove of blackmail material against the long list of members on his client list.

I recently released my first open-source tool:\ 👉 nostr-signal-filter

It fetches and formats your latest top-level Nostr note or long-form article, cleans up any embedded links using TinyURL, and outputs a clean version ready for reposting to:

• LinkedIn

• Facebook

• X / Twitter

---

⚙️ Built for Simplicity

The stack is intentionally minimal:

• Python + WebSockets + Bech32

• TinyURL API for link shortening

• Dockerized CLI usage:

bash

CopyEdit

docker run --rm -e PUBKEY=npub1yourpubkeyhere nostr-fetcher > latest.md

From idea to working repo took under 3 hours — including debugging, Docker tweaks, README cleanup, and tagging a clean release.\ \ This most certainly would have taken much longer if I had done this all without ChatGPTs' help.\ \ 🖼️ Example Output (latest.md)

Google says that Android 16 is slated to feature an optional high security mode. Cool.

Advanced Protection has a bunch of requested features that address the kinds of threats we worry about.

It's the kind of 'turn this one thing on if you face elevated risk' that we've been asking for from Google.

And likely reflects some learning after Google watched Apple 's Lockdown Mode play out. I see a lot of value in this..

Here are some features I'm excited to see play out:

The Intrusion Logging feature is interesting & is going to impose substantial cost on attackers trying to hide evidence of exploitation. Logs get e2ee encrypted into the cloud. This one is spicy.

The Offline Lock, Inactivity Reboot & USB protection will frustrate non-consensual attempts to physically grab device data.

Memory Tagging Extension is going to make a lot of attack & exploitation categories harder.

2G Network Protection & disabling Auto-connect to insecure networks are going to address categories of threat from things like IMSI catchers & hostile WiFi.

I'm curious about some other features such as:

Spam & Scam detection: Google messages feature that suggests message content awareness and some kind of scanning.

Scam detection for Phone by Google is interesting & coming later. The way it is described suggests phone conversation awareness. This also addresses a different category of threat than the stuff above. I can see it addressing a whole category of bad things that regular users (& high risk ones too!) face. Will be curious how privacy is addressed or if this done purely locally. Getting messy: Friction points? I see Google thinking these through, but I'm going to add a potential concern: what will users do when they encounter friction? Will they turn this off & forget to re-enable? We've seen users turn off iOS Lockdown Mode when they run into friction for specific websites or, say, legacy WiFi. They then forget to turn it back on. And stay vulnerable.

Bottom line: users disabling Apple's Lockdown Mode for a temporary thing & leaving it off because they forget to turn it on happens a lot. This is a serious % of users in my experience...

And should be factored into design decisions for similar modes. I feel like a good balance is a 'snooze button' or equivalent so that users can disable all/some features for a brief few minute period to do something they need to do, and then auto re-enable.

Winding up:

I'm excited to see how Android Advanced Protection plays with high risk users' experiences. I'm also super curious whether the spam/scam detection features may also be helpful to more vulnerable users (think: aging seniors)...

Niche but important:

Some users, esp. those that migrated to security & privacy-focused Android distros because of because of the absence of such a feature are clear candidates for it... But they may also voice privacy concerns around some of the screening features. Clear communication from the Google Security / Android team will be key here.

1. O que é um Aromaterapeuta?

O aromaterapeuta é um profissional especializado na prática da Aromaterapia, responsável pelo uso adequado de óleos essenciais, ervas aromáticas, águas florais e destilados herbais para fins terapêuticos.

A atuação desse profissional envolve diferentes métodos de aplicação, como inalação, uso tópico, sempre considerando a segurança e a necessidade individual do cliente. A Aromaterapia pode auxiliar na redução do estresse, alívio de dores crônicas, relaxamento muscular e melhora da respiração, entre outros benefícios.

Além disso, os aromaterapeutas podem trabalhar em conjunto com outros profissionais da saúde para oferecer um tratamento complementar em diversas condições. Como já mencionado no artigo sobre "Como evitar processos alérgicos na prática da Aromaterapia", é essencial ter acompanhamento profissional, pois os óleos essenciais são altamente concentrados e podem causar reações adversas se utilizados de forma inadequada.

---

2. Como um Aromaterapeuta Pode Ajudar?

Você pode procurar um aromaterapeuta para diferentes necessidades, como:

✔ Questões Emocionais e Psicológicas

Auxílio em momentos de luto, divórcio, demissão ou outras situações desafiadoras.

Apoio na redução do estresse, ansiedade e insônia.

Vale lembrar que, em casos de transtornos psiquiátricos, a Aromaterapia deve ser usada como terapia complementar, associada ao tratamento médico.

✔ Questões Físicas

Dores musculares e articulares.

Problemas respiratórios como rinite, sinusite e tosse.

Distúrbios digestivos leves.

Dores de cabeça e enxaquecas. Nesses casos, a Aromaterapia pode ser um suporte, mas não substitui a medicina tradicional para identificar a origem dos sintomas.

✔ Saúde da Pele e Cabelos

Tratamento para acne, dermatites e psoríase.

Cuidados com o envelhecimento precoce da pele.

Redução da queda de cabelo e controle da oleosidade do couro cabeludo.

✔ Bem-estar e Qualidade de Vida

Melhora da concentração e foco, aumentando a produtividade.

Estímulo da disposição e energia.

Auxílio no equilíbrio hormonal (TPM, menopausa, desequilíbrios hormonais).

Com base nessas necessidades, o aromaterapeuta irá indicar o melhor tratamento, calculando doses, sinergias (combinação de óleos essenciais), diluições e técnicas de aplicação, como inalação, uso tópico ou difusão.

---

3. Como Funciona uma Consulta com um Aromaterapeuta?

Uma consulta com um aromaterapeuta é um atendimento personalizado, onde são avaliadas as necessidades do cliente para a criação de um protocolo adequado. O processo geralmente segue estas etapas:

✔ Anamnese (Entrevista Inicial)

Perguntas sobre saúde física, emocional e estilo de vida.

Levantamento de sintomas, histórico médico e possíveis alergias.

Definição dos objetivos da terapia (alívio do estresse, melhora do sono, dores musculares etc.).

✔ Escolha dos Óleos Essenciais

Seleção dos óleos mais indicados para o caso.

Consideração das propriedades terapêuticas, contraindicações e combinações seguras.

✔ Definição do Método de Uso

O profissional indicará a melhor forma de aplicação, que pode ser:

Inalação: difusores, colares aromáticos, vaporização.

Uso tópico: massagens, óleos corporais, compressas.

Banhos aromáticos e escalda-pés. Todas as diluições serão ajustadas de acordo com a segurança e a necessidade individual do cliente.

✔ Plano de Acompanhamento

Instruções detalhadas sobre o uso correto dos óleos essenciais.

Orientação sobre frequência e duração do tratamento.

Possibilidade de retorno para ajustes no protocolo.

A consulta pode ser realizada presencialmente ou online, dependendo do profissional.

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. 🫡

GA, plebs. The latest episode of Bitcoin And is out, and, as always, the chicanery is running rampant. Let’s break down the biggest topics I covered, and if you want the full, unfiltered rant, make sure to listen to the episode linked below.

House Democrats’ MEME Act: A Bad Joke?

House Democrats are proposing a bill to ban presidential meme coins, clearly aimed at Trump’s and Melania’s ill-advised token launches. While grifters launching meme coins is bad, this bill is just as ridiculous. If this legislation moves forward, expect a retaliatory strike exposing how politicians like Pelosi and Warren mysteriously amassed their fortunes. Will it pass? Doubtful. But it’s another sign of the government’s obsession with regulating everything except itself.

Senate Banking’s First Digital Asset Hearing: The Real Target Is You

Cynthia Lummis chaired the first digital asset hearing, and—surprise!—it was all about control. The discussion centered on stablecoins, AML, and KYC regulations, with witnesses suggesting Orwellian measures like freezing stablecoin transactions unless pre-approved by authorities. What was barely mentioned? Bitcoin. They want full oversight of stablecoins, which is really about controlling financial freedom. Expect more nonsense targeting self-custody wallets under the guise of stopping “bad actors.”

Bank of America and PayPal Want In on Stablecoins

Bank of America’s CEO openly stated they’ll launch a stablecoin as soon as regulation allows. Meanwhile, PayPal’s CEO paid for a hat using Bitcoin—not their own stablecoin, Pi USD. Why wouldn’t he use his own product? Maybe he knows stablecoins aren’t what they’re hyped up to be. Either way, the legacy financial system is gearing up to flood the market with stablecoins, not because they love crypto, but because it’s a tool to extend U.S. dollar dominance.

MetaPlanet Buys the Dip

Japan’s MetaPlanet issued $13.4M in bonds to buy more Bitcoin, proving once again that institutions see the writing on the wall. Unlike U.S. regulators who obsess over stablecoins, some companies are actually stacking sats.

UK Expands Crypto Seizure Powers

Across the pond, the UK government is pushing legislation to make it easier to seize and destroy crypto linked to criminal activity. While they frame it as going after the bad guys, it’s another move toward centralized control and financial surveillance.

Bitcoin Tools & Tech: Arc, SatoChip, and Nunchuk

Some bullish Bitcoin developments: ARC v0.5 is making Bitcoin’s second layer more efficient, SatoChip now supports Taproot and Nostr, and Nunchuk launched a group wallet with chat, making multisig collaboration easier.

The Bottom Line

The state is coming for financial privacy and control, and stablecoins are their weapon of choice. Bitcoiners need to stay focused, keep their coins in self-custody, and build out parallel systems. Expect more regulatory attacks, but don’t let them distract you—just keep stacking and transacting in ways they can’t control.

Bitcoin has always been a narrative revolution disguised as code. White paper, cypherpunk lore, pizza‑day legends - every block is a paragraph in the world’s most relentless epic. But code alone rarely converts the skeptic; it’s the camp‑fire myth that slips past the prefrontal cortex and shakes hands with the limbic system. People don’t adopt protocols first - they fall in love with protagonists.

Early adopters heard the white‑paper hymn, but most folks need characters first: a pizza‑day dreamer; a mother in a small country, crushed by the cost of remittance; a Warsaw street vendor swapping złoty for sats. When their arcs land, the brain releases a neurochemical OP_RETURN which says, “I belong in this plot.” That’s the sly roundabout orange pill: conviction smuggled inside catharsis.

That’s why, from 22–25 May in Warsaw’s Kinoteka, the Bitcoin Film Fest is loading its reels with rebellion. Each documentary, drama, and animated rabbit‑hole is a stealth wallet, zipping conviction straight into the feels of anyone still clasped within the cold claw of fiat. You come for the plot, you leave checking block heights.

Here's the clip of the sermon from the episode:

If you don't know where your posts are, you might as well just stay in the centralized Twitter. You either take control of your relay lists, or they will control you. Amethyst offers several lists of relays for our users. We are going to go one by one to help clarify what they are and which options are best for each one.

Public Home/Outbox Relays

Home relays store all YOUR content: all your posts, likes, replies, lists, etc. It's your home. Amethyst will send your posts here first. Your followers will use these relays to get new posts from you. So, if you don't have anything there, they will not receive your updates.

Home relays must allow queries from anyone, ideally without the need to authenticate. They can limit writes to paid users without affecting anyone's experience.

This list should have a maximum of 3 relays. More than that will only make your followers waste their mobile data getting your posts. Keep it simple. Out of the 3 relays, I recommend: - 1 large public, international relay: nos.lol, nostr.mom, relay.damus.io, etc. - 1 personal relay to store a copy of all your content in a place no one can delete. Go to relay.tools and never be censored again. - 1 really fast relay located in your country: paid options like http://nostr.wine are great

Do not include relays that block users from seeing posts in this list. If you do, no one will see your posts.

Public Inbox Relays

This relay type receives all replies, comments, likes, and zaps to your posts. If you are not getting notifications or you don't see replies from your friends, it is likely because you don't have the right setup here. If you are getting too much spam in your replies, it's probably because your inbox relays are not protecting you enough. Paid relays can filter inbox spam out.

Inbox relays must allow anyone to write into them. It's the opposite of the outbox relay. They can limit who can download the posts to their paid subscribers without affecting anyone's experience.

This list should have a maximum of 3 relays as well. Again, keep it small. More than that will just make you spend more of your data plan downloading the same notifications from all these different servers. Out of the 3 relays, I recommend: - 1 large public, international relay: nos.lol, nostr.mom, relay.damus.io, etc. - 1 personal relay to store a copy of your notifications, invites, cashu tokens and zaps. - 1 really fast relay located in your country: go to nostr.watch and find relays in your country

Terrible options include: - nostr.wine should not be here. - filter.nostr.wine should not be here. - inbox.nostr.wine should not be here.

DM Inbox Relays

These are the relays used to receive DMs and private content. Others will use these relays to send DMs to you. If you don't have it setup, you will miss DMs. DM Inbox relays should accept any message from anyone, but only allow you to download them.

Generally speaking, you only need 3 for reliability. One of them should be a personal relay to make sure you have a copy of all your messages. The others can be open if you want push notifications or closed if you want full privacy.

Good options are: - inbox.nostr.wine and auth.nostr1.com: anyone can send messages and only you can download. Not even our push notification server has access to them to notify you. - a personal relay to make sure no one can censor you. Advanced settings on personal relays can also store your DMs privately. Talk to your relay operator for more details. - a public relay if you want DM notifications from our servers.

Make sure to add at least one public relay if you want to see DM notifications.

Private Home Relays

Private Relays are for things no one should see, like your drafts, lists, app settings, bookmarks etc. Ideally, these relays are either local or require authentication before posting AND downloading each user\'s content. There are no dedicated relays for this category yet, so I would use a local relay like Citrine on Android and a personal relay on relay.tools.

Keep in mind that if you choose a local relay only, a client on the desktop might not be able to see the drafts from clients on mobile and vice versa.

Search relays:

This is the list of relays to use on Amethyst's search and user tagging with @. Tagging and searching will not work if there is nothing here.. This option requires NIP-50 compliance from each relay. Hit the Default button to use all available options on existence today: - nostr.wine - relay.nostr.band - relay.noswhere.com

Local Relays:

This is your local storage. Everything will load faster if it comes from this relay. You should install Citrine on Android and write ws://localhost:4869 in this option.

General Relays:

This section contains the default relays used to download content from your follows. Notice how you can activate and deactivate the Home, Messages (old-style DMs), Chat (public chats), and Global options in each.

Keep 5-6 large relays on this list and activate them for as many categories (Home, Messages (old-style DMs), Chat, and Global) as possible.

Amethyst will provide additional recommendations to this list from your follows with information on which of your follows might need the additional relay in your list. Add them if you feel like you are missing their posts or if it is just taking too long to load them.

My setup

Here's what I use: 1. Go to relay.tools and create a relay for yourself. 2. Go to nostr.wine and pay for their subscription. 3. Go to inbox.nostr.wine and pay for their subscription. 4. Go to nostr.watch and find a good relay in your country. 5. Download Citrine to your phone.

Then, on your relay lists, put:

Public Home/Outbox Relays: - nostr.wine - nos.lol or an in-country relay. - .nostr1.com

Public Inbox Relays - nos.lol or an in-country relay - .nostr1.com

DM Inbox Relays - inbox.nostr.wine - .nostr1.com

Private Home Relays - ws://localhost:4869 (Citrine) - .nostr1.com (if you want)

Search Relays - nostr.wine - relay.nostr.band - relay.noswhere.com

Local Relays - ws://localhost:4869 (Citrine)

General Relays - nos.lol - relay.damus.io - relay.primal.net - nostr.mom

And a few of the recommended relays from Amethyst.

Final Considerations

Remember, relays can see what your Nostr client is requesting and downloading at all times. They can track what you see and see what you like. They can sell that information to the highest bidder, they can delete your content or content that a sponsor asked them to delete (like a negative review for instance) and they can censor you in any way they see fit. Before using any random free relay out there, make sure you trust its operator and you know its terms of service and privacy policies.

An honest response to objections — and an answer to the most important question: why does any of this matter?

\ Statement: Deflation is not the enemy, but a natural state in an age of technological progress.\ Criticism: in real macroeconomics, long-term deflation is linked to depressions.\ Deflation discourages borrowers and investors, and makes debt heavier.\ Natural ≠ Safe.

1. “Deflation → Depression, Debt → Heavier”

This is true in a debt-based system. Yes, in a fiat economy, debt balloons to the sky, and without inflation it collapses.

But Bitcoin offers not “deflation for its own sake,” but an environment where you don’t need to be in debt to survive. Where savings don’t melt away.\ Jeff Booth said it clearly:

“Technology is inherently deflationary. Fighting deflation with the printing press is fighting progress.”

You don’t have to take on credit to live in this system. Which means — deflation is not an enemy, but an ally.

💡 People often confuse two concepts:

1. That deflation doesn’t work in an economy built on credit and leverage — that’s true.

2. That deflation itself is bad — that’s a myth.

📉 In reality, deflation is the natural state of a free market when technology makes everything cheaper.

Historical example:\ In the U.S., from the Civil War to the early 1900s, the economy experienced gentle deflation — alongside economic growth, employment expansion, and industrial boom.\ Prices fell: for example, a sack of flour cost \~$1.00 in 1865 and \~$0.50 in 1895 — and there was no crisis, because wages held and productivity increased.

Modern example:\ Consumer electronics over the past 20–30 years are a vivid example of technological deflation:\ – What cost $5,000 in 2000 (e.g., a 720p plasma TV) now costs $300 and delivers 10× better quality.\ – Phones, computers, cameras — all became far more powerful and cheaper at the same time.\ That’s how tech-driven deflation works: you get more for less.

📌 Bitcoin doesn’t make the world deflationary. It just doesn’t fight against deflation, unlike the fiat model that fights to preserve its debt pyramid.\ It stops punishing savers and rewards long-term thinkers.

Even economists often confuse organic tech deflation with crisis-driven (debt) deflation.

---

\ \ Statement: We’ve never lived in a truly free market — central banks and issuance always existed.\ Criticism: ideological statement.\ A truly “free” market is utopian.\ Banks and monetary issuance emerged in response to crises.\ A market without arbiters is not always fair, especially under imperfect competition.

2. “The Free Market Is a Utopia”

Yes, “pure markets” are rare. But what we have today isn’t regulation — it’s centralized power in the hands of central banks and cartels.

Bitcoin offers rules without rulers. 21 million. No one can change the issuance. It’s not ideology — it’s code instead of trust. And it has worked for 15 years.

💬 People often say that banks and centralized issuance emerged as a response to crises — as if the market couldn’t manage on its own.\ But if a system needs to be “rescued” again and again through money printing… maybe the problem isn’t freedom, but the system itself?

📌 Crises don’t disprove the value of free markets. They only reveal how fragile a system becomes when the price of money is set not by the market, but by a boardroom vote.\ Bitcoin doesn’t magically eliminate crises — it removes the root cause: the ability to manipulate money in someone’s interest.

---

\ \ Statement: Inflation is an invisible tax, especially on the poor and working class.\ Criticism: partly true: inflation can reduce debt burden, boost employment.\ The state indexes social benefits. Under stable inflation, compensators can work. Under deflation, things might be worse (mass layoffs, defaults).

3. “Inflation Can Help”

Theoretically — yes. Textbooks say moderate inflation can reduce debt burdens and stimulate consumption and jobs.\ But in practice — it works as a stealth tax, especially on those without assets. The wealthy escape — into real estate, stocks, funds.\ But the poor and working class lose purchasing power because their money is held in cash — and cash devalues.

💬 As Lyn Alden says:

“When your money can’t hold value, you’re forced to become an investor — even if you just want to save and live.”

The state may index pensions or benefits — but always with a lag, and always less than actual price increases.\ If bread rises 15% and your payment increase is 5%, you got poorer, even if the number on paper went up.

💥 We live in an inflationary system of everything:\ – Inflationary money\ – Inflationary products\ – Inflationary content\ – And now even inflationary minds

🧠 This is more than just rising prices — it’s a degradation of reality perception. You’re always rushing, everything loses meaning.\ But when did the system start working against you?

📉 What went wrong after 1971?

This chart shows that from 1948 to the early 1970s, productivity and wages grew together.\ But after the end of the gold standard in 1971 — the connection broke. Productivity kept rising, but real wages stalled.

👉 This means: you work more, better, faster — but buy less.

🔗 Source: wtfhappenedin1971.com

When you must spend today because tomorrow it’ll be worth less — that’s rewarding impulse and punishing long-term thinking.

Bitcoin offers a different environment:\ – Savings work\ – Long-term thinking is rewarded\ – The price of the future is calculated, not forced by a printing press

📌 Inflation can be a tool. But in government hands, it became a weapon — a slow, inevitable upward redistribution of wealth.

---

\ \ Statement: War is not growth, but a reallocation of resources into destruction.

Criticism: war can spur technological leaps (Internet, GPS, nuclear energy — all from military programs). "Military Keynesianism" was a real model.

4. “War Drives R&D”

Yes, wars sometimes give rise to tech spin-offs: Internet, GPS, nuclear power — all originated from military programs.

But that doesn’t make war a source of progress — it makes tech a byproduct of catastrophe.

“War reallocates resources toward destruction — not growth.”

Progress doesn’t happen because of war — it happens despite it.

If scientific breakthroughs require a million dead and burnt cities — maybe you’ve built your economy wrong.

💬 Even Michael Saylor said:

“If you need war to develop technology — you’ve built civilization wrong.”

No innovation justifies diverting human labor, minds, and resources toward destruction.\ War is always the opposite of efficiency — more is wasted than created.

🧠 Bitcoin, on the other hand, is an example of how real R&D happens without violence.\ No taxes. No army. Just math, voluntary participation, and open-source code.

📌 Military Keynesianism is not a model of progress — it’s a symptom of a sick monetary system that needs destruction to reboot.

Bitcoin shows that coordination without violence is possible.\ This is R&D of a new kind: based not on destruction, but digital creation.

---

Statement: Bitcoin isn’t “Gold 1.0,” but an improved version: divisible, verifiable, unseizable.

Criticism: Bitcoin has no physical value; "unseizability" is a theory;\ Gold is material and autonomous.

5. “Bitcoin Has No Physical Value”

And gold does? Just because it shines?

Physical form is no guarantee of value.\ Real value lies in: scarcity, reliable transfer, verifiability, and non-confiscatability.

Gold is:\ – Hard to divide\ – Hard to verify\ – Expensive to store\ – Easy to seize

💡 Bitcoin is the first store of value in history that is fully free from physical limitations, and yet:\ – Absolutely scarce (21M, forever)\ – Instantly transferable over the Internet\ – Cryptographically verifiable\ – Controlled by no government

🔑 Bitcoin’s value lies in its liberation from the physical.\ It doesn’t need to be “backed” by gold or oil. It’s backed by energy, mathematics, and ongoing verification.

“Price is what you pay, value is what you get.” — Warren Buffett

When you buy bitcoin, you’re not paying for a “token” — you’re gaining access to a network of distributed financial energy.

⚡️ What are you really getting when you own bitcoin?\ – A key to a digital asset that can’t be faked\ – The ability to send “crystallized energy” anywhere on Earth (it takes 10 minutes on the base L1 layer, or instantly via the Lightning Network)\ – A role in a new accounting system that runs 24/7/365\ – Freedom: from banks, borders, inflation, and force

📉 Bitcoin doesn’t require physical value — because it creates value:\ Through trust, scarcity, and energy invested in mining.\ And unlike gold, it was never associated with slavery.

---

Statement: There’s no “income without risk” in Bitcoin: just hold — you preserve; want more — invest, risk, build.

Criticism: contradicts HODL logic; speculation remains dominant behavior.

6. “Speculation Dominates”

For now — yes. That’s normal for the early phase of a new technology. Awareness doesn’t come instantly.

What matters is not the motive of today’s buyer — but what they’re buying.

📉 A speculator may come and go — but the asset remains.\ And this asset is the only one in history that will never exist again. 21 million. Forever.

📌 Look deeper. Bitcoin has:\ – No CEO\ – No central issuer\ – No inflation\ – No “off switch”\ 💡 It was fairly distributed — through mining, long before ASICs existed. In the early years, bitcoin was spent and exchanged — not hoarded. Only those who truly believed in it are still holding it today.

💡 It’s not a stock. Not a startup. Not someone’s project.\ It’s a new foundation for trust.\ It’s opting out of a system where freedom is a privilege you’re granted under conditions.

🧠 People say: “Bitcoin can be copied.”\ Theoretically — yes.\ Practically — never.

Here’s what you’d need to recreate Bitcoin:\ – No pre-mine\ – A founder who disappears and never sells\ – No foundation or corporation\ – Tens of thousands of nodes worldwide\ – 701 million terahashes of hash power\ – Thousands of devs writing open protocols\ – Hundreds of global conferences\ – Millions of people defending digital sovereignty\ – All that without a single marketing budget

That’s all.

🔁 Everything else is an imitation, not a creation.\ Just like you can’t “reinvent fire” — Bitcoin can only exist once.

---

Statements:\ **The Russia's '90s weren’t a free market — just anarchic chaos without rights protection.\ **Unlike fiat or even dollars, Bitcoin is the first asset with real defense — from governments, inflation, even thugs.\ *And yes, even if your barber asks about Bitcoin — maybe it's not a bubble, but a sign that inflation has already hit everyone.

Criticism: Bitcoin’s protection isn’t universal — it works only with proper handling and isn’t available to all.\ Some just want to “get rich.”\ None of this matters because:

1. Bitcoin’s volatility (-30% in a week, +50% in a month) makes it unusable for price planning or contracts.

2. It can’t handle mass-scale usage.

3. To become currency, geopolitical will is needed — and without the first two, don’t even talk about the third.\ Also: “Bitcoin is too complicated for the average person.”

7. “It’s Too Complex for the Masses”

It’s complex — if you’re using L1 (Layer 1). But even grandmas use Telegram. In El Salvador, schoolkids buy lunch with Lightning. My barber installed Wallet of Satoshi in minutes right in front of me — and I now pay for my haircut via Lightning.

UX is just a matter of time. And it’s improving. Emerging tools:\ Cashu, Fedimint, Fedi, Wallet of Satoshi, Phoenix, Proton Wallet, Swiss Bitcoin Pay, Bolt Card / CoinCorner (NFC cards for Lightning payments).

This is like the internet in 1995:\ It started with modems — now it’s 4K streaming.

💸 Now try sending a regular bank transfer abroad:\ – you need to type a long IBAN\ – add SWIFT/BIC codes\ – include the recipient’s full physical address (!), compromising their privacy\ – sometimes add extra codes or “purpose of payment”\ – you might get a call from your bank “just to confirm”\ – no way to check the status — the money floats somewhere between correspondent/intermediary banks\ – weekends or holidays? Banks are closed\ – and don’t forget the limits, restrictions, and potential freezes

📌 With Bitcoin, you just scan a QR code and send.\ 10 minutes on-chain = final settlement.\ Via Lightning = instant and nearly free.\ No bureaucracy. No permission. No borders.

---

8. “Can’t Handle the Load”

A common myth.\ Yes, Bitcoin L1 processes about 7 transactions per second — intentionally. It’s not built to be Visa. It’s a financial protocol, just like TCP/IP is a network protocol. TCP/IP isn’t “fast” or “slow” — the experience depends on the infrastructure built on top: servers, routers, hardware. In the ’90s, it delivered text. Today, it streams Netflix. The protocol didn’t change — the stack did.

Same with Bitcoin: L1 defines rules, security, finality.\ Scaling and speed? That’s the second layer’s job.

To understand scale:

| Network | TPS (Transactions/sec) | | --- | --- | | Visa | up to 24,000 | | Mastercard | \~5,000 | | PayPal | \~193 | | Litecoin | \~56 | | Ethereum | \~20 | | Bitcoin | \~7 |

\ ⚡️ Enter Lightning Network — Bitcoin’s “fast lane.”\ It allows millions of transactions per second, instantly and nearly free.

And it’s not a sidechain.

❗️ Lightning is not a separate network.\ It uses real Bitcoin transactions (2-of-2 multisig). You can close the channel to L1 at any time. It’s not an alternative — it’s a native extension built into Bitcoin.\ Also evolving: Ark, Fedimint, eCash — new ways to scale and add privacy.

📉 So criticizing Bitcoin for “slowness” is like blaming TCP/IP because your old modem won’t stream YouTube.\ The protocol isn’t the problem — it’s the infrastructure.

🛡️ And by the way: Visa crashes more often than Bitcoin.

---

9. “We Need Geopolitical Will”

Not necessarily. All it takes is the will of the people — and leaders willing to act. El Salvador didn’t wait for G20 approval or IMF blessings. Since 2001, the country had used the US dollar as its official currency, abandoning its own colón. But that didn’t save it from inflation or dependency on foreign monetary policy. In 2021, El Salvador became the first country to recognize Bitcoin as legal tender. Since March 13, 2024, they’ve been purchasing 1 BTC daily, tracked through their public address:

🔗 Address\ 📅 First transaction

This policy became the foundation of their Strategic Bitcoin Reserve (SBR) — a state-led effort to accumulate Bitcoin as a national reserve asset for long-term stability and sovereignty.

Their example inspired others.

In March 2025, U.S. President Donald Trump signed an executive order creating the Strategic Bitcoin Reserve of the USA, to be funded through confiscated Bitcoin and digital assets.\ The idea: accumulate, don’t sell, and strategically expand the reserve — without extra burden on taxpayers.

Additionally, Senator Cynthia Lummis (Wyoming) proposed the BITCOIN Act, targeting the purchase of 1 million BTC over five years (\~5% of the total supply).\ The plan: fund it via revaluation of gold certificates and other budget-neutral strategies.

📚 More: Strategic Bitcoin Reserve — Wikipedia

👉 So no global consensus is required. No IMF greenlight.\ All it takes is conviction — and an understanding that the future of finance lies in decentralized, scarce assets like Bitcoin.

---

10. “-30% in a week, +50% in a month = not money”

True — Bitcoin is volatile. But that’s normal for new technologies and emerging money. It’s not a bug — it’s a price discovery phase. The world is still learning what this asset is.

📉 Volatility is the price of entry.\ 📈 But the reward is buying the future at a discount.

As Michael Saylor put it:

“A tourist sees Niagara Falls as chaos — roaring, foaming, spraying water.\ An engineer sees immense energy.\ It all depends on your mental model.”

Same with Bitcoin. Speculators see chaos. Investors see structural scarcity. Builders see a new financial foundation.

💡 Now consider gold:

👉 After the gold standard was abandoned in 1971, the price of gold skyrocketed from around \~$300 to over $2,700 (adjusted to 2023 dollars) by 1980. Along the way, it experienced extreme volatility — with crashes of 40–60% even amid the broader uptrend.\ 💡 (\~$300 is the inflation-adjusted equivalent of about $38 in 1971 dollars)\ 📈 Source: Gold Price Chart — Macrotrends\ \ Nobody said, “This can’t be money.” \ Because money is defined not by volatility, but by scarcity, adoption, and trust — which build over time.

📊 The more people save in Bitcoin, the more its volatility fades.

This is a journey — not a fixed state.

We don’t judge the internet by how it worked in 1994.\ So why expect Bitcoin to be the “perfect currency” in 2025?

It grows bottom-up — without regulators’ permission.\ And the longer it survives, the stronger it becomes.

Remember how many times it’s been declared dead.\ And how many times it came back — stronger.

---

📊 Gold vs. Bitcoin: Supply Comparison

This chart shows the key difference between the two hard assets:

🔹 Gold — supply keeps growing.\ Mining may be limited, but it’s still inflationary.\ Each year, there’s more — with no known cap: new mines, asteroid mining, recycling.

🔸 Bitcoin — capped at 21 million.\ The emission schedule is public, mathematically predictable, and ends completely around 2140.

🧠 Bottom line:\ Gold is good.\ Bitcoin is better — for predictability and scarcity.

💡 As Saifedean Ammous said:

“Gold was the best monetary good… until Bitcoin.”

### While we argue — fiat erodes every day.

No matter your view on Bitcoin, just show me one other asset that is simultaneously:

– immune to devaluation by decree\ – impossible to print more of\ – impossible to confiscate by a centralized order\ – impossible to counterfeit\ – and, most importantly — transferable across borders without asking permission from a bank, a state, or a passport

💸 Try sending $10,000 through PayPal from Iran to Paraguay, or Bangladesh to Saint Lucia.\ Good luck. PayPal doesn't even work there.

Now open a laptop, type 12 words — and you have access to your savings anywhere on Earth.

🌍 Bitcoin doesn't ask for permission.\ It works for everyone, everywhere, all the time.

📌 There has never been anything like this before.

Bitcoin is the first asset in history that combines:

– digital nature\ – predictable scarcity\ – absolute portability\ – and immunity from tyranny

💡 As Michael Saylor said:

“Bitcoin is the first money in human history not created by bankers or politicians — but by engineers.”

You can own it with no bank.\ No intermediary.\ No passport.\ No approval.

That’s why Bitcoin isn’t just “internet money” or “crypto” or “digital gold.”\ It may not be perfect — but it’s incorruptible.\ And it’s not going away.\ It’s already here.\ It is the foundation of a new financial reality.

---

🔒 This is not speculation. This is a peaceful financial revolution.\ 🪙 This is not a stock. It’s money — like the world has never seen.\ ⛓️ This is not a fad. It’s a freedom protocol.

And when even the barber starts asking about Bitcoin — it’s not a bubble.\ It’s a sign that the system is breaking.\ And people are looking for an exit.

For the first time — they have one.

---

💼 This is not about investing. It’s about the dignity of work.

Imagine a man who cleans toilets at an airport every day.

Not a “prestigious” job.\ But a crucial one.\ Without him — filth, bacteria, disease.

He shows up on time. He works with his hands.

And his money? It devalues. Every day.

He doesn’t work less — often he works more than those in suits.\ But he can afford less and less — because in this system, honest labor loses value each year.

Now imagine he’s paid in Bitcoin.

Not in some “volatile coin,” but in hard money — with a limited supply.\ Money that can’t be printed, reversed, or devalued by central banks.

💡 Then he could:

– Stop rushing to spend, knowing his labor won’t be worth less tomorrow\ – Save for a dream — without fear of inflation eating it away\ – Feel that his time and effort are respected — because they retain value

Bitcoin gives anyone — engineer or janitor — a way out of the game rigged against them.\ A chance to finally build a future where savings are real.

This is economic justice.\ This is digital dignity.

📉 In fiat, you have to spend — or your money melts.\ 📈 In Bitcoin, you choose when to spend — because it’s up to you.

🧠 In a deflationary economy, both saving and spending are healthy:

You don’t scramble to survive — you choose to create.

🎯 That’s true freedom.

When even someone cleaning floors can live without fear —\ and know that their time doesn’t vanish... it turns into value.

---

🧱 The Bigger Picture

Bitcoin is not just a technology — it’s rooted in economic philosophy.\ The Austrian School of Economics has long argued that sound money, voluntary exchange, and decentralized decision-making are prerequisites for real prosperity.\ Bitcoin doesn’t reinvent these ideas — it makes them executable.

📉 Inflation doesn’t just erode savings.\ It quietly destroys quality of life.\ You work more — and everything becomes worse:\ – food is cheaper but less nutritious\ – homes are newer but uglier and less durable\ – clothes cost more but fall apart in months\ – streaming is faster, but your attention span collapses\ This isn’t just consumerism — it’s the economics of planned obsolescence.

🧨 Meanwhile, the U.S. debt has exceeded 3x its GDP.\ And nobody wants to buy U.S. bonds anymore — so the U.S. has to buy its own debt.\ Yes: printing money to buy the IOUs you just printed.\ This is the endgame of fiat.

🎭 Bonds are often sold as “safe.”\ But in practice, they are a weapon — especially abroad.\ The U.S. and IMF give loans to developing countries.\ But when those countries can’t repay (due to rigged terms or global economic headwinds), they’re forced to sell land, resources, or strategic assets.\ Both sides lose: the debtor collapses under the weight of debt, while the creditor earns resentment and instability.\ This isn’t cooperation — it’s soft colonialism enabled by inflation.

📌 Bitcoin offers a peaceful exit.\ A financial system where money can’t be created out of thin air.\ Where savings work.\ Where dignity is restored — even for those who clean toilets.

@ 9e69e420:d12360c2

Vice President J.D. Vance addressed the Munich Security Conference, criticizing European leaders for undermining free speech and traditional values. He claimed that the biggest threat to Europe is not from external enemies but from internal challenges. Vance condemned the arrest of a British man for praying near an abortion clinic and accused European politicians of censorship.

He urged leaders to combat illegal immigration and questioned their democratic practices. “There is a new sheriff in town,” he said, referring to President Trump. Vance's remarks were unexpected, as many anticipated discussions on security or Ukraine. His speech emphasized the need for Europe to share the defense burden to ensure stability and security.

My favorite line in any Marvel movie ever is in “Captain America.” After Captain America launches seemingly a hopeless assault on Red Skull’s base and is captured, we get this line:

“Arrogance may not be a uniquely American trait, but I must say, you do it better than anyone.”

Yesterday, I came across a comment on the song Devil Went Down to Georgia that had a very similar feel to it:

America has seemingly always been arrogant, in a uniquely American way. Manifest Destiny, for instance. The rest of the world is aware of this arrogance, and mocks Americans for it. A central point in modern US politics is the deriding of racist, nationalist, supremacist Americans.

That’s not what I see. I see American Arrogance as not only a beautiful statement about what it means to be American. I see it as an ode to the greatness of humanity in its purest form.

For most countries, saying “our nation is the greatest” is, in fact, twinged with some level of racism. I still don’t have a problem with it. Every group of people should be allowed to feel pride in their accomplishments. The destruction of the human spirit since the end of World War 2, where greatness has become a sin and weakness a virtue, has crushed the ability of people worldwide to strive for excellence.

But I digress. The fears of racism and nationalism at least have a grain of truth when applied to other nations on the planet. But not to America.

That’s because the definition of America, and the prototype of an American, has nothing to do with race. The definition of Americanism is freedom. The founding of America is based purely on liberty. On the God-given rights of every person to live life the way they see fit.

American Arrogance is not a statement of racial superiority. It’s barely a statement of national superiority (though it absolutely is). To me, when an American comments on the greatness of America, it’s a statement about freedom. Freedom will always unlock the greatness inherent in any group of people. Americans are definitionally better than everyone else, because Americans are freer than everyone else. (Or, at least, that’s how it should be.)

In Devil Went Down to Georgia, Johnny is approached by the devil himself. He is challenged to a ridiculously lopsided bet: a golden fiddle versus his immortal soul. He acknowledges the sin in accepting such a proposal. And yet he says, “God, I know you told me not to do this. But I can’t stand the affront to my honor. I am the greatest. The devil has nothing on me. So God, I’m gonna sin, but I’m also gonna win.”

Die zwei mächtigsten Krieger sind Geduld und Zeit. \ Leo Tolstoi

Zum Wohle unserer Gesundheit, unserer Leistungsfähigkeit und letztlich unseres Glücks ist es wichtig, die eigene Energie bewusst zu pflegen. Das gilt umso mehr für an gesellschaftlichen Themen interessierte, selbstbewusste und kritisch denkende Menschen. Denn für deren Wahrnehmung und Wohlbefinden waren und sind die rasanten, krisen- und propagandagefüllten letzten Jahre in Absurdistan eine harte Probe.

Nur wer regelmäßig Kraft tankt und Wege findet, mit den Herausforderungen umzugehen, kann eine solche Tortur überstehen, emotionale Erschöpfung vermeiden und trotz allem zufrieden sein. Dazu müssen wir erkunden, was uns Energie gibt und was sie uns raubt. Durch Selbstreflexion und Achtsamkeit finden wir sicher Dinge, die uns erfreuen und inspirieren, und andere, die uns eher stressen und belasten.

Die eigene Energie ist eng mit unserer körperlichen und mentalen Gesundheit verbunden. Methoden zur Förderung der körperlichen Gesundheit sind gut bekannt: eine ausgewogene Ernährung, regelmäßige Bewegung sowie ausreichend Schlaf und Erholung. Bei der nicht minder wichtigen emotionalen Balance wird es schon etwas komplizierter. Stress abzubauen, die eigenen Grenzen zu kennen oder solche zum Schutz zu setzen sowie die Konzentration auf Positives und Sinnvolles wären Ansätze.

Der emotionale ist auch der Bereich, über den «Energie-Räuber» bevorzugt attackieren. Das sind zum Beispiel Dinge wie Überforderung, Perfektionismus oder mangelhafte Kommunikation. Social Media gehören ganz sicher auch dazu. Sie stehlen uns nicht nur Zeit, sondern sind höchst manipulativ und erhöhen laut einer aktuellen Studie das Risiko für psychische Probleme wie Angstzustände und Depressionen.

Geben wir negativen oder gar bösen Menschen keine Macht über uns. Das Dauerfeuer der letzten Jahre mit Krisen, Konflikten und Gefahren sollte man zwar kennen, darf sich aber davon nicht runterziehen lassen. Das Ziel derartiger konzertierter Aktionen ist vor allem, unsere innere Stabilität zu zerstören, denn dann sind wir leichter zu steuern. Aber Geduld: Selbst vermeintliche «Sonnenköniginnen» wie EU-Kommissionspräsidentin von der Leyen fallen, wenn die Zeit reif ist.

Es ist wichtig, dass wir unsere ganz eigenen Bedürfnisse und Werte erkennen. Unsere Energiequellen müssen wir identifizieren und aktiv nutzen. Dazu gehören soziale Kontakte genauso wie zum Beispiel Hobbys und Leidenschaften. Umgeben wir uns mit Sinnhaftigkeit und lassen wir uns nicht die Energie rauben!

Mein Wahlspruch ist schon lange: «Was die Menschen wirklich bewegt, ist die Kultur.» Jetzt im Frühjahr beginnt hier in Andalusien die Zeit der «Ferias», jener traditionellen Volksfeste, die vor Lebensfreude sprudeln. Konzentrieren wir uns auf die schönen Dinge und auf unsere eigenen Talente – soziale Verbundenheit wird helfen, unsere innere Kraft zu stärken und zu bewahren.

Issue 11 already - I will be including numbers going forward to make past letters easier to find and refer to. The past two weeks I have been on vacation - my first real vacation is a couple of years. Monday I am back to work for a bit. I have decided to work from here rather than subject myself to more international travel - we are still refugees from the insanity in Hong Kong. We really have been relaxing and enjoying life on the island. Levada hikes and Jeep tours!

220415 Jeep tour - Cabo Girao, Porto Moniz, Fanal and Ponto do Sol - Madeira

We had plenty of time to relax and enjoy life. Madeira is a fantastic place to visit with lots to see and do and even more weather!. I did think that HK was mountainous - but Madeira is next level! Portuguese is also something else; have not yet made much progress but we did not try much and English will generally suffice. As you see in the video above, Madeira is getting serious about attracting Digital Nomads and as you will see below they have forward-thinking local government - exactly as foreseen in my top book pick - The Sovereign Indvidual.

I did get to read quite a lot of interesting books and material - will be sharing insights below and going forward. Happy to discuss too - that offer is still open.

Among other things I got to appreciate more the Apple ecosystem and the seamless integration between Mac, iPhone and iPad - in combination with working with no/limited WiFi and using tethering from my CalyxOS Pixel. Strong privacy is important and Apple scores reasonably well - though you will want to take some additional precautions, I have been enjoying reading my kindle on all platforms and listening to the audio-books with reading-location syncing (fantastic). I am considering sharing tips and tricks on secure setups as well as aspects that I find particularly useful - do talk to me if you have questions or suggestions.

Bitcoin BTC

Given how important Bitcoin already is and will become I think it is right that I should include a section here with relevant news, insights and provocations to discuss. Note that Bitcoin is different from "Crypto"; do not get them mixed up!

• Madeira is not just trying to be friendly to digital nomads - photo above and Ponto do Sol. Last week the President of the Government of Madeira, Miguel Albuquerque attended the Miami conference to announce that his government will “work to create a fantastic environment for bitcoin in Madeira.” This is part of the Game Theory of Bitcoin Adoption by Nation States

• Announcing Taro, Multi-Asset Bitcoin & Lightning** **- this has potential to be something really big. It complements, and may even be better than, Jack Mallers' Strike. Their Blog post is here and the Wiki with the detailed specification is here.

• Michael Saylor is one of today's pre-eminent thinkers and communicators. Listen and learn from his revcent interview with Lex Friedman.

• SLP365 Anita Posch - Bitcoin For Fairness in Zimbabwe and Zambia — A great interview by Stephan Livera. Key takeaways: Learn how to use it before you really need it. if it works in Zimbabwe and Namibia it will work anywhere It’s still early and governments will give no help; rather they will be busy putting sticks in the wheels and sand in the gears…

• For those who look for education on Bitcoin - a starting point can be Anita Posch's The Art of (L)earning Bitcoin with many useful resources linked.

Discovery of the week - Obsidian

For years I have been an avid notetaker. I caught the bug when I did Electronic Engineering at Southampton University and we had to keep a "lab book". Ever since then in my professional work I kept a notebook and took daily notes. Recently this evolved into taking notes on computer. With the arrival of online working and screen-sharing such notes can be very useful and this unleased new value in note-taking.

For personal notes I found great value with Apple Notes - a tool that has improved dramatically in recent years and works perfectly on Mac, iPhone and iPad. However, like many notetakers I often felt that I was "missing a trick". The reality is that searching and retrieval is not as easy as you want it to be and it's hard to reassemble and repurpose your collected information into new output.

In recent years I have considered using several tools but found none of them compelling enough to put in the time to learn and adopt. There is also the fear of "lock in" and endless subscriptions to pay - as anyone who has used Evernote will know!

Big thank you to Rachel for this one. She did get me thinking and encouraged me to give Obsidian another try - I had looked at it last year but it felt overwhelming compared to Apple Notes - I could never have imagined how great it could be!

The absolute best overview of Obsidian and how to use it is FromSergio - his playlist is required watching. Particular highlights:

• Kindle Highlights - this is a superbly useful feature that normally you can only get with a subscription service - do buy the developer a coffee!

• No Lock-in - your files are simple markdown and you have full control

• Works perfectly on Mac and iPhones using iCloud - no annoying sync subscription to pay for

• It's free for personal use - no payment or annoying subscription

• Lots of high quality training material readily available and a great community of people to help you

Reading

• Empires Rise and Fall this extracts and summarises from John Glubb's paper of nearly 100 years ago, The Fate of Empires - I think you call that foresight! I do identify with his frustrations about how history has been taught considering how important it is to learn from past generations.

• The Sovereign Individual is required reading for everyone - I did dip back into it a few times over the last week or so, making Kindle highlights that magically sync into Obsidian - how great is that! If you read nothing else, read chapter 7.

• From Paris to Karachi – Regime Change is In the Air - Tom Luongo is a most interesting character and he does speak his mind. Read and consider. You might prefer to listen to him discussing with Marty.

• Aleks Svetski: The Remnant, The Parasite & The Masses - inspired by the incredible 1930’s essay by Albert J Nock; Isaiah’s Job. Aleks discusses this in his Wake Up podcast - also recommended.

• In my TBR queue (to be read): Atlas Shrugged by Ayn Rand - I must admit, I am in intrigued by Odolena's review in addition to Aleks' recommendation.

• I also think that I need to restart on (and finish) Foundation by Isaac Asimov - after watching Odolena's review of it!

• ...and I need to add Meditations by Marcus Aurelius - again inspired by Odolena's review and I have seen others recommend it too!

Watching and Listening

• Joe Blogs: Who is BUYING Russian Oil Now? Can Europe really change SUPPLIERS & are SANCTIONS Working? - do stop and think - in who's name are the governments implementing all these extreme measures - go back and re-read section "So what can you do about it?" in issue 9

• Rupert Murdochizing The Internet — The Cyberlaw Podcast — whether you agree with him or not Stewart Baker is just the best podcast provocateur!

• AntiWarhol, Culture Creation, & The Pop Art Syndicate — One of The Higherside Chats - perhaps this might open your mind and make you question some things. The rabbit hole goes deep.

• How Britain's Bankers Made Billions From The End Of Empire. At the demise of British Empire, City of London financial interests created a web of offshore secrecy jurisdictions that captured wealth from across the globe and hid it behind obscure financial structures in a web of offshore islands.

• Secret City - A film about the City of London, the Corporation that runs it.

• How things get Re-Priced when a Currency Fails — An important explainer from Joe Brown of The Heresy Financial Podcast — keep an eye out for signs!

• E76: Elon vs. Twitter — the All-In Podcast. I do not agree with all these boyz say but it is interesting to listen to see how the Silicon Valley types think. David Sacks nails it, and Chamath is not far behind! If you were in any doubt as to how corrupt things are this should put you right!

I didn’t take a course on “prompt engineering.” I didn’t memorize secret formulas or chase viral hacks.

What I did do was treat it like a system.

Just like in software:

Write → Compile → Test → Debug → Repeat

With AI, the loop feels just as familiar:

Prompt → Output → Edit → Re-prompt

That’s not magic. That’s engineering.

---

When someone asked me, “How can you trust AI for anything serious?”\ I told them: “Same way we trust the internet — not because the network’s reliable, but because the protocol is.”

AI is no different. The key is building systems around it:

• Multiple models if needed

• Human-in-the-loop verification

• Layered editing and real discernment

---

It’s Not That Different From Other Engineering

Once you stop treating AI like a black box and start treating it like a tool, the whole experience changes.

The prompt isn’t a spell. It’s a spec.\ The response isn’t a prophecy. It’s a build.\ And your discernment? That’s your QA layer.

---

What I Actually Use It For

• Brainstorming titles and refining headlines

• Drafting posts that I shape and filter

• Running content through for edge cases

• Exploring theological or philosophical questions

And yes — I want it to be useful. I am building to make a living, not just to make noise. But I don’t lead with monetization. I lead with clarity — and build toward sustainability.

---

Final Thought

If you’re waiting for a course to teach you how to “do AI,” maybe just start by building something real. Test it. Edit it. Use it again. That’s engineering.

Shoutout to Dr. C (ChatGPT) for helping me articulate this.

If this post sparked anything for you, zap a few sats ⚡ — every bit helps me keep building with conviction.

April already and we are still refugees from the madness in HK. During March I had quite a few family matters that took priority and I also needed to work for two weeks. April is a similar schedule but we flew to Madeira for a change of scene and so that I could have a full 2-weeks off - my first real holiday in quite a few years!

We are staying in an airBnB in Funchal - an experience that I can totally recommend - video below! Nice to have an apartment that is fully equipped in a central location and no hassle for a few weeks. While here we are making the most of the great location and all the local possibiliites.

Elsewhere in the world

Things are clearly not going great around the world. If you are still confused as to why these things are happening, do go back and read the previous Letter from HK section "Why? How did we get here?"

You should be in no doubt that the "Great Reset" with its supporting "Great Narrative" is in full swing.. This is it - it is not a drill. For additional insights the following are recommended.

• Jeff Booth discusses clearly and unemotionally with Pomp - Inflation is theft from humanity by the world governments

• James' summary of Day 2 of the Miami conference - Peter Thiel (wow) and a fantastic explainer from Saifedean on the costs of the current corrupt financial system

• James' summary of Day 3 of the Miami conference - listen in particular to the words of wisdom from Michael Saylor and Lyn Alden

• Layered Money - The corruption of the system will blow your mind once you understand it…

• This is BIG: Strike Is Bringing Freedom To Retail Merchants

• Mark summarises Ray's book: Things will go faster and slower than you want!

• Thoughtful words from George - evil is at work - be in no doubt..

• Wow - My mind is blown. Must listen to John Carvalho - what clear ambition and answers to every question!

• Related to the John Carvalho discussion. Likely these two options will end up complementing each other

On the personal and inspirational side

Advantage of time off work is that I have more time to read, listen and watch things that interest me. It really is a privilege that so much high quality material is so readily available. Do not let it go to waste. A few fabulous finds (and some re-finds) from this past week:

• Ali Abdaal's bookshelf review just blew my mind! For the full list of books with links see the text under his video. So many inspirations and his delivery is perfect.

• Gotta recommend Ali's 21 Life Lessons. I have been following him since he was student in Cambridge five years ago - his personal and professional growth and what he achieves (now with his team) is truely staggering.

• Also his 15 books to read in 2022 - especially this one!

• I also keep going back to Steve Jobs giving the 2005 Stanford Commencement address Three stories from his life - listen and be inspired - especially story #3

You will know that I am a fan of Audio Books and also Kindle - recently I am starting to use Whispersync where you get the Kindle- and Audio-books together for a nice price. This makes it easier to take notes (using Mac or iPad Kindle reader) while getting the benefit of having the book read to you by a professional reader.

I have also been inspired by a few people pushing themselves to do more reading - like this girl and Ali himself with his tips. Above all: just do it and do not get stuck on something that does not work for you!

Books that I am reading - Audio and Kindle!

• The Final Empire: Mistborn, Book 1 - this is a new genre for me - I rather feel that it might be a bit too complicated for my engineering mind - let's see

• Die with Zero: Getting All You Can from Your Money and Your Life - certainly provocative and obvious if you think about it but 99% do the opposite!

• Chariots of the Gods - a classic by Erich von Daniken (written in 1968) - I have been inspired by his recent YT video appearances. Thought provoking and leads you to many possibilities.

So what's it like in Funchal, Madeira?

Do check out HitTheRoadMadeira's walking tour around Funchal

There has been a good bit of discussion on Nostr over the past few days about the merits of zaps as a method of engaging with notes, so after writing a rather lengthy article on the pros of a strategic Bitcoin reserve, I wanted to take some time to chime in on the much more fun topic of digital engagement.

Let's begin by defining a couple of things:

Nostr is a decentralized, censorship-resistance protocol whose current biggest use case is social media (think Twitter/X). Instead of relying on company servers, it relies on relays that anyone can spin up and own their own content. Its use cases are much bigger, though, and this article is hosted on my own relay, using my own Nostr relay as an example.

Zap is a tip or donation denominated in sats (small units of Bitcoin) sent from one user to another. This is generally done directly over the Lightning Network but is increasingly using Cashu tokens. For the sake of this discussion, how you transmit/receive zaps will be irrelevant, so don't worry if you don't know what Lightning or Cashu are.

If we look at how users engage with posts and follows/followers on platforms like Twitter, Facebook, etc., it becomes evident that traditional social media thrives on engagement farming. The more outrageous a post, the more likely it will get a reaction. We see a version of this on more visual social platforms like YouTube and TikTok that use carefully crafted thumbnail images to grab the user's attention to click the video. If you'd like to dive deep into the psychology and science behind social media engagement, let me know, and I'd be happy to follow up with another article.

In this user engagement model, a user is given the option to comment or like the original post, or share it among their followers to increase its signal. They receive no value from engaging with the content aside from the dopamine hit of the original experience or having their comment liked back by whatever influencer they provide value to. Ad revenue flows to the content creator. Clout flows to the content creator. Sales revenue from merch and content placement flows to the content creator. We call this a linear economy -- the idea that resources get created, used up, then thrown away. Users create content and farm as much engagement as possible, then the content is forgotten within a few hours as they move on to the next piece of content to be farmed.

What if there were a simple way to give value back to those who engage with your content? By implementing some value-for-value model -- a circular economy. Enter zaps.

Unlike traditional social media platforms, Nostr does not actively use algorithms to determine what content is popular, nor does it push content created for active user engagement to the top of a user's timeline. Yes, there are "trending" and "most zapped" timelines that users can choose to use as their default, but these use relatively straightforward engagement metrics to rank posts for these timelines.

That is not to say that we may not see clients actively seeking to refine timeline algorithms for specific metrics. Still, the beauty of having an open protocol with media that is controlled solely by its users is that users who begin to see their timeline gamed towards specific algorithms can choose to move to another client, and for those who are more tech-savvy, they can opt to run their own relays or create their own clients with personalized algorithms and web of trust scoring systems.

Zaps enable the means to create a new type of social media economy in which creators can earn for creating content and users can earn by actively engaging with it. Like and reposting content is relatively frictionless and costs nothing but a simple button tap. Zaps provide active engagement because they signal to your followers and those of the content creator that this post has genuine value, quite literally in the form of money—sats.

I have seen some comments on Nostr claiming that removing likes and reactions is for wealthy people who can afford to send zaps and that the majority of people in the US and around the world do not have the time or money to zap because they have better things to spend their money like feeding their families and paying their bills. While at face value, these may seem like valid arguments, they, unfortunately, represent the brainwashed, defeatist attitude that our current economic (and, by extension, social media) systems aim to instill in all of us to continue extracting value from our lives.

Imagine now, if those people dedicating their own time (time = money) to mine pity points on social media would instead spend that time with genuine value creation by posting content that is meaningful to cultural discussions. Imagine if, instead of complaining that their posts get no zaps and going on a tirade about how much of a victim they are, they would empower themselves to take control of their content and give value back to the world; where would that leave us? How much value could be created on a nascent platform such as Nostr, and how quickly could it overtake other platforms?

Other users argue about user experience and that additional friction (i.e., zaps) leads to lower engagement, as proven by decades of studies on user interaction. While the added friction may turn some users away, does that necessarily provide less value? I argue quite the opposite. You haven't made a few sats from zaps with your content? Can't afford to send some sats to a wallet for zapping? How about using the most excellent available resource and spending 10 seconds of your time to leave a comment? Likes and reactions are valueless transactions. Social media's real value derives from providing monetary compensation and actively engaging in a conversation with posts you find interesting or thought-provoking. Remember when humans thrived on conversation and discussion for entertainment instead of simply being an onlooker of someone else's life?

If you've made it this far, my only request is this: try only zapping and commenting as a method of engagement for two weeks. Sure, you may end up liking a post here and there, but be more mindful of how you interact with the world and break yourself from blind instinct. You'll thank me later.

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.

@ e3ba5e1a:5e433365

I got into a friendly discussion on X regarding health insurance. The specific question was how to deal with health insurance companies (presumably unfairly) denying claims? My answer, as usual: get government out of it!

The US healthcare system is essentially the worst of both worlds:

• Unlike full single payer, individuals incur high costs
• Unlike a true free market, regulation causes increases in costs and decreases competition among insurers

I'm firmly on the side of moving towards the free market. (And I say that as someone living under a single payer system now.) Here's what I would do:

• Get rid of tax incentives that make health insurance tied to your employer, giving individuals back proper freedom of choice.
• Reduce regulations significantly.

• In the short term, some people will still get rejected claims and other obnoxious behavior from insurance companies. We address that in two ways:

  1. Due to reduced regulations, new insurance companies will be able to enter the market offering more reliable coverage and better rates, and people will flock to them because they have the freedom to make their own choices.
  2. Sue the asses off of companies that reject claims unfairly. And ideally, as one of the few legitimate roles of government in all this, institute new laws that limit the ability of fine print to allow insurers to escape their responsibilities. (I'm hesitant that the latter will happen due to the incestuous relationship between Congress/regulators and insurers, but I can hope.)

Will this magically fix everything overnight like politicians normally promise? No. But it will allow the market to return to a healthy state. And I don't think it will take long (order of magnitude: 5-10 years) for it to come together, but that's just speculation.

And since there's a high correlation between those who believe government can fix problems by taking more control and demanding that only credentialed experts weigh in on a topic (both points I strongly disagree with BTW): I'm a trained actuary and worked in the insurance industry, and have directly seen how government regulation reduces competition, raises prices, and harms consumers.

And my final point: I don't think any prior art would be a good comparison for deregulation in the US, it's such a different market than any other country in the world for so many reasons that lessons wouldn't really translate. Nonetheless, I asked Grok for some empirical data on this, and at best the results of deregulation could be called "mixed," but likely more accurately "uncertain, confused, and subject to whatever interpretation anyone wants to apply."

อลิซต้องการจ่ายเงินให้กับบ๊อบแต่โหนดของบิตคอยน์ในระบบหลายพันโหนดจะตรวจสอบธุรกรรมของเธอ โดยไม่รู้ว่าอลิซหรือบ๊อบเป็นใคร ละเราต้องการรักษาความเป็นส่วนตัวของพวกเขาไว้เช่นนี้ อลิซจำเป็นต้องสื่อสารว่าบ๊อบควรได้รับบิตคอยน์บางส่วนของเธอโดยไม่เชื่อมโยงแง่มุมใด ๆ ของธุรกรรมนั้นกับตัวตนในโลกจริงของบ๊อบ หรือกับการชำระเงินด้วยบิตคอยน์ครั้งอื่น ๆ ที่บ๊อบได้รับ อลิซใช้ต้องทำให้มั่นใจว่ามีเพียแค่บ๊อบเท่านั้นที่สามารถใช้จ่ายบิตคอยน์ที่เขาได้รับต่อไปได้

ในบิตคอยน์ไวท์เปเปอร์ได้อธิบายถึงแผนการที่เรียบง่ายมากสำหรับการบรรลุเป้าหมายเหล่านั้น ดังที่แสดงในรูปด้านล่างนี้

ตัวของผู้รับอย่างบ๊อบเองจะได้รับบิตคอยน์ไปยัง public key ของเขาที่ถูกลงนามโดยผู้จ่ายอย่างอลิซ โดยบิตคอยน์ที่อลิซนำมาจ่ายนั้นก็ได้รับมาจากที่ใครสักคนส่งมาที่ public key ของเธอ และเธอก็ใช้ private key ของเธอในการลงนามเพื่อสร้างลายเซ็นของเธอและโหนดต่าง ๆ ของบิตคอยน์จะทำการตรวจสอบว่าลายเซ็นของอลิซผูกมัดกับเอาต์พุตของฟังก์ชันแฮชซึ่งตัวมันเองผูกมัดกับ public key ของบ๊อบและรายละเอียดธุรกรรมอื่นๆ

ในบทนี้เราจะพิจารณาpublic key private key Digital signatrue และ hash function จากนั้นใช้ทั้งหมดนี้ร่วมกันเพื่ออธิบาย address ที่ใช้โดยซอฟต์แวร์บิตคอยน์สมัยใหม่

Public Key Cryptography (การเข้ารหัสของ public key)

ระบบเข้ารหัสของ public key ถูกคิดค้นขึ้นในทศวรรษ 1970 มาจากรากฐานทางคณิตศาสตร์สำหรับความปลอดภัยของคอมพิวเตอร์และข้อมูลสมัยใหม่

นับตั้งแต่การคิดค้นระบบเข้ารหัส public key ได้มีการค้นพบฟังก์ชันทางคณิตศาสตร์ที่เหมาะสมหลายอย่าง เช่น การยกกำลังของจำนวนเฉพาะและการคูณของเส้นโค้งวงรี โดยฟังก์ชันทางคณิตศาสตร์เหล่านี้สามารถคำนวณได้ง่ายในทิศทางหนึ่ง แต่เป็นไปไม่ได้ที่จะคำนวณในทิศทางตรงกันข้ามโดยใช้คอมพิวเตอร์และอัลกอริทึมที่มีอยู่ในปัจจุบัน จากฟังก์ชันทางคณิตศาสตร์เหล่านี้ การเข้ารหัสลับช่วยให้สามารถสร้างลายเซ็นดิจิทัลที่ไม่สามารถปลอมแปลงได้และบิตคอยน์ได้ใช้การบวกและการคูณของเส้นโค้งวงรีเป็นพื้นฐานสำหรับการเข้ารหัสลับของมัน

ในบิตคอยน์ เราสามารถใช้ระบบเข้ารหัส public key เพื่อสร้างคู่กุญแจที่ควบคุมการเข้าถึงบิตคอยน์ คู่กุญแจประกอบด้วย private key และ public key ที่ได้มาจาก private key public keyใช้สำหรับรับเงิน และ private key ใช้สำหรับลงนามในธุรกรรมเพื่อใช้จ่ายเงิน

ความสัมพันธ์ทางคณิตศาสตร์ระหว่าง public key และ private key ที่ช่วยให้ private key สามารถใช้สร้างลายเซ็นบนข้อความได้ ลายเซ็นเหล่านี้สามารถตรวจสอบความถูกต้องกับ public key ได้โดยไม่เปิดเผย private key

TIP: ในการใช้งานซอฟแวร์กระเป๋าเงินบิตคอยน์บสงอัน จะทำการเก็บ private key และ public key ถูกเก็บไว้ด้วยกันในรูปแบบคู่กุญแจเพื่อความสะดวก แต่อย่างไรก็ตาม public key สามารถคำนวณได้จาก private key ดังนั้นการเก็บเพียง private key เท่านั้นก็เป็นไปได้เช่นกัน

bitcoin wallet มักจะทำการรวบรวมคู่กุญแต่ละคู่ ซึ่งจะประกอบไปด้วย private key และ public key โดย private key จะเป็นตัวเลขที่ถูกสุ่มเลือกขึ้นมา และเราขะใช้เส้นโค้งวงรี ซึ่งเป็นฟังก์ชันการเข้ารหัสทางเดียว เพื่อสร้าง public key ขึ้นมา

ทำไมจึงใช้การเข้ารหัสแบบอสมมาตร

ทำไมการเข้ารหัสแบบอสมมาตรจึงถูกใช้บิตคอยน์? มันไม่ได้ถูกใช้เพื่อ "เข้ารหัส" (ทำให้เป็นความลับ) ธุรกรรม แต่คุณสมบัติที่มีประโยชน์ของการเข้ารหัสแบบอสมมาตรคือความสามารถในการสร้าง ลายเซ็นดิจิทัล private key สามารถนำไปใช้กับธุรกรรมเพื่อสร้างลายเซ็นเชิงตัวเลข ลายเซ็นนี้สามารถสร้างได้เฉพาะโดยผู้ที่มีความเกี่ยวข้องกับ private key เท่านั้น แต่อย่างไรก็ตาม ทุกคนที่สามารถเข้าถึง public key และธุรกรรมสามารถใช้สิ่งเหล่านี้เพื่อ ตรวจสอบ ลายเซ็นได้ คุณสมบัติที่มีประโยชน์นี้ของการเข้ารหัสแบบอสมมาตรทำให้ทุกคนสามารถตรวจสอบลายเซ็นทุกรายการในทุกธุรกรรมได้ ในขณะที่มั่นใจว่าเฉพาะเจ้าของ private key เท่านั้นที่สามารถสร้างลายเซ็นที่ถูกต้องได้

Private keys

private key เป็นเพียงตัวเลขที่ถูกสุ่มขึ้น และการควบคุม private key ก็เป็นรากฐานสำคัญที่ทำให้เจ้าชองกุญแจดอกนี้สามารถควบคุมบิตคอยน์ทั้งหมดที่มีความเกี่ยวข้องกับ public key ที่คู่กัน private key นั้นใช้ในการสร้างลายเซ็นดิจิทัลที่ใช้ในการเคลื่อนย้ายบิตคอยน์ เราจำเป็นต้องเก็บ private key ให้เป็นความลับตลอดเวลา เพราะการเปิดเผยมันให้กับบุคคลอื่นนั้นก็เปรียบเสมือนกับการนำอำนาจในการควบคุมบิตคอยน์ไปให้แก่เขา นอกจากนี้ private key ยังจำเป็นต้องได้รับการสำรองข้อมูลและป้องกันจากการสูญหายโดยไม่ตั้งใจ เพราะหากเราได้ทำมันสูญหายไป จะไม่สามารถกู้คืนได้ และบิตคอยน์เหล่านั้นจะถูกปกป้องโดยกุญแจที่หายไปนั้นตลอดกาลเช่นกัน

TIP: private key ของบิตคอยน์นั้นเป็นเพียงแค่ตัวเลข คุณสามารถสร้างมันได้โดยใช้เพียงเหรียญ ดินสอ และกระดาษ โดยการโยนเหรียญเพียง 256 ครั้งจะทำให้คุณได้เลขฐานสองที่สามารถใช้เป็น private key ของบิตคอยน์ จากนั้นคุณสามารถใช้มันในการคำนวณหา public key แต่อย่างไรก็ตาม โปรดระมัดระวังเกี่ยวกับการเลือใช้วิธีการสุ่มที่ไม่สมบูรณ์ เพราะนั่นอาจลดความปลอดภัยของ private key และบิตคอยน์ที่มัมปกป้องอยู่อย่างมีนัยสำคัญ

ขั้นตอนแรกและสำคัญที่สุดในการสร้างกุญแจคือการหาแหล่งที่มาของความสุ่มที่ปลอดภัย (ซึ่งเรียกว่า เอนโทรปี) การสร้างกุญแจของบิตคอยน์นั้นเกือบเหมือนกับ "เลือกตัวเลขระหว่าง 1 และ 2^256" ซึ่งวิธีที่แน่นอนที่คุณใช้ในการเลือกตัวเลขนั้นไม่สำคัญตราบใดที่มันไม่สามารถคาดเดาหรือทำซ้ำได้ โดยปกติแล้วซอฟต์แวร์ของบิตคอยน์มักจะใช้ตัวสร้างตัวเลขสุ่มที่มีความปลอดภัยทางการเข้ารหัสเพื่อสร้างเอนโทรปี 256 บิต

สิ่งที่สำคัญในเรื่องนี้คือ private key สามารถเป็นตัวเลขใดๆ ระหว่าง 0 และ n - 1 (รวมทั้งสองค่า) โดยที่ n เป็นค่าคงที่ (n = 1.1578 × 10^77 ซึ่งน้อยกว่า 2^256 เล็กน้อย) ซึ่งกำหนดอยู่ใน elliptic curve ที่ใช้ใน Bitcoin ในการสร้างกุญแจดังกล่าว เราสุ่มเลือกเลขขนาด 256 บิตและตรวจสอบว่ามันน้อยกว่า n ในแง่ของการเขียนโปรแกรม โดยปกติแล้วสิ่งนี้ทำได้โดยการป้อนสตริงของบิตสุ่มที่ใหญ่กว่า ซึ่งรวบรวมจากแหล่งที่มาของความสุ่มที่มีความปลอดภัยทางการเข้ารหัส เข้าไปในอัลกอริทึมแฮช SHA256 ซึ่งจะสร้างค่าขนาด 256 บิตที่สามารถตีความเป็นตัวเลขได้อย่างสะดวก หากผลลัพธ์น้อยกว่า n เราจะได้กุญแจส่วนตัวที่เหมาะสม มิฉะนั้น เราก็เพียงแค่ลองอีกครั้งด้วยตัวเลขสุ่มอื่น

คำเตือน: อย่าเขียนโค้ดของคุณเองเพื่อสร้างตัวเลขสุ่ม หรือใช้ตัวสร้างตัวเลขสุ่ม "แบบง่าย" ที่มีให้ในภาษาโปรแกรมของคุณ ใช้ตัวสร้างตัวเลขสุ่มเทียมที่มีความปลอดภัยทางการเข้ารหัส (CSPRNG) จากแหล่งที่มีเอนโทรปีเพียงพอ ศึกษาเอกสารของไลบรารีตัวสร้างตัวเลขสุ่มที่คุณเลือกเพื่อให้มั่นใจว่ามีความปลอดภัยทางการเข้ารหัส การใช้งาน CSPRNG ที่ถูกต้องมีความสำคัญอย่างยิ่งต่อความปลอดภัยของกุญแจ

ต่อไปนี้คือกุญแจส่วนตัว (k) ที่สร้างขึ้นแบบสุ่มซึ่งแสดงในรูปแบบเลขฐานสิบหก (256 บิตแสดงเป็น 64 หลักเลขฐานสิบหก โดยแต่ละหลักคือ 4 บิต): 1E99423A4ED27608A15A2616A2B0E9E52CED330AC530EDCC32C8FFC6A526AEDD

TIP: จำนวนที่เป็นไปได้ของ private key ทั้งหมดนั้นมีอยู่ 2^256 เป็นตัวเลขที่ใหญ่มากจนยากจะจินตนาการได้ มันมีค่าประมาณ 10^77 (เลข 1 ตามด้วยเลข 0 อีก 77 ตัว) ในระบบเลขฐานสิบ เพื่อให้เข้าใจง่ายขึ้น ลองเปรียบเทียบกับจักรวาลที่เรามองเห็นได้ซึ่งนักวิทยาศาสตร์ประมาณการว่ามีอะตอมทั้งหมดประมาณ 10^80 อะตอม นั่นหมายความว่าช่วงค่าของกุญแจส่วนตัว Bitcoin มีขนาดใกล้เคียงกับจำนวนอะตอมทั้งหมดในจักรวาลที่เรามองเห็นได้

การอธิบายเกี่ยวกับวิทยาการเข้ารหัสแบบเส้นโค้งวงรี (Elliptic Curve Cryptography)

วิทยาการเข้ารหัสแบบเส้นโค้งวงรี (ECC) เป็นประเภทหนึ่งของการเข้ารหัสแบบอสมมาตรหรือ public key ซึ่งอาศัยหลักการของปัญหาลอการิทึมแบบไม่ต่อเนื่อง โดยแสดงออกผ่านการบวกและการคูณบนจุดต่างๆ ของเส้นโค้งวงรี

บิตคอยน์ใช้เส้นโค้งวงรีเฉพาะและชุดค่าคงที่ทางคณิตศาสตร์ ตามที่กำหนดไว้ในมาตรฐานที่เรียกว่า secp256k1 ซึ่งกำหนดโดยสถาบันมาตรฐานและเทคโนโลยีแห่งชาติ (NIST) เส้นโค้ง secp256k1 ถูกกำหนดโดยฟังก์ชันต่อไปนี้ ซึ่งสร้างเส้นโค้งวงรี: y² = (x³ + 7) บนฟิลด์จำกัด (F_p) หรือ y² mod p = (x³ + 7) mod p

โดยที่ mod p (มอดูโลจำนวนเฉพาะ p) แสดงว่าเส้นโค้งนี้อยู่บนฟิลด์จำกัดของอันดับจำนวนเฉพาะ p ซึ่งเขียนได้เป็น F_p โดย p = 2^256 – 2^32 – 2^9 – 2^8 – 2^7 – 2^6 – 2^4 – 1 ซึ่งเป็นจำนวนเฉพาะที่มีค่ามหาศาล

บิตคอยน์ใช้เส้นโค้งวงรีที่ถูกนิยามบนฟิลด์จำกัดของอันดับจำนวนเฉพาะแทนที่จะอยู่บนจำนวนจริง ทำให้มันมีลักษณะเหมือนรูปแบบของจุดที่กระจัดกระจายในสองมิติ ซึ่งทำให้ยากต่อการจินตนาการภาพ อย่างไรก็ตาม คณิตศาสตร์ที่ใช้นั้นเหมือนกับเส้นโค้งวงรีบนจำนวนจริง

ตัวอย่างเช่น การเข้ารหัสลับด้วยเส้นโค้งวงรี: การแสดงภาพเส้นโค้งวงรีบน F(p) โดยที่ p=17 แสดงเส้นโค้งวงรีเดียวกันบนฟิลด์จำกัดของอันดับจำนวนเฉพาะ 17 ที่มีขนาดเล็กกว่ามาก ซึ่งแสดงรูปแบบของจุดบนตาราง

เส้นโค้งวงรี secp256k1 ที่ใช้ในบิตคอยน์สามารถนึกถึงได้ว่าเป็นรูปแบบของจุดที่ซับซ้อนมากกว่าบนตารางที่มีขนาดใหญ่มหาศาลจนยากจะเข้าใจได้

ตัวอย่างเช่น จุด P ที่มีพิกัด (x, y) ต่อไปนี้เป็นจุดที่อยู่บนเส้นโค้ง secp256k1: P = (55066263022277343669578718895168534326250603453777594175500187360389116729240, 32670510020758816978083085130507043184471273380659243275938904335757337482424) เราสามารถใช้ Python เพื่อยืนยันว่าจุดนี้อยู่บนเส้นโค้งวงรีได้ตามตัวอย่างนี้: ตัวอย่างที่ 1: การใช้ Python เพื่อยืนยันว่าจุดนี้อยู่บนเส้นโค้งวงรี ``` Python 3.10.6 (main, Nov 14 2022, 16:10:14) [GCC 11.3.0] on linux Type "help", "copyright", "credits" or "license" for more information.

p = 115792089237316195423570985008687907853269984665640564039457584007908834671663 x = 55066263022277343669578718895168534326250603453777594175500187360389116729240 y = 32670510020758816978083085130507043184471273380659243275938904335757337482424 (x ** 3 + 7 - y**2) % p 0 ``` ผลลัพธ์เป็น 0 ซึ่งแสดงว่าจุดนี้อยู่บนเส้นโค้งวงรีจริง เพราะเมื่อแทนค่า x และ y ลงในสมการ y² = (x³ + 7) mod p แล้ว ทั้งสองด้านของสมการมีค่าเท่ากัน

ในคณิตศาสตร์ของเส้นโค้งวงรี มีจุดที่เรียกว่า "จุดที่อนันต์" (point at infinity) ซึ่งมีบทบาทคล้ายกับศูนย์ในการบวก บนคอมพิวเตอร์ บางครั้งจุดนี้แทนด้วย x = y = 0 (ซึ่งไม่เป็นไปตามสมการเส้นโค้งวงรี แต่เป็นกรณีพิเศษที่สามารถตรวจสอบได้ง่าย)

มีตัวดำเนินการ + ที่เรียกว่า "การบวก" ซึ่งมีคุณสมบัติคล้ายกับการบวกแบบดั้งเดิมของจำนวนจริงที่เด็กๆ เรียนในโรงเรียน เมื่อมีจุดสองจุด P1 และ P2 บนเส้นโค้งวงรี จะมีจุดที่สาม P3 = P1 + P2 ซึ่งอยู่บนเส้นโค้งวงรีเช่นกัน

ในเชิงเรขาคณิต จุดที่สาม P3 นี้คำนวณได้โดยการลากเส้นระหว่าง P1 และ P2 เส้นนี้จะตัดกับเส้นโค้งวงรีที่จุดเพิ่มเติมอีกหนึ่งจุดพอดี เรียกจุดนี้ว่า P3' = (x, y) จากนั้นให้สะท้อนกับแกน x เพื่อได้ P3 = (x, -y)

มีกรณีพิเศษบางกรณีที่อธิบายความจำเป็นของ "จุดที่อนันต์":

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

• 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

For years American bitcoin miners have argued for more efficient and free energy markets. It benefits everyone if our energy infrastructure is as efficient and robust as possible. Unfortunately, broken incentives have led to increased regulation throughout the sector, incentivizing less efficient energy sources such as solar and wind at the detriment of more efficient alternatives.

The result has been less reliable energy infrastructure for all Americans and increased energy costs across the board. This naturally has a direct impact on bitcoin miners: increased energy costs make them less competitive globally.

Bitcoin mining represents a global energy market that does not require permission to participate. Anyone can plug a mining computer into power and internet to get paid the current dynamic market price for their work in bitcoin. Using cellphone or satellite internet, these mines can be located anywhere in the world, sourcing the cheapest power available.

Absent of regulation, bitcoin mining naturally incentivizes the build out of highly efficient and robust energy infrastructure. Unfortunately that world does not exist and burdensome regulations remain the biggest threat for US based mining businesses. Jurisdictional arbitrage gives miners the option of moving to a friendlier country but that naturally comes with its own costs.

Enter AI. With the rapid development and release of AI tools comes the requirement of running massive datacenters for their models. Major tech companies are scrambling to secure machines, rack space, and cheap energy to run full suites of AI enabled tools and services. The most valuable and powerful tech companies in America have stumbled into an accidental alliance with bitcoin miners: THE NEED FOR CHEAP AND RELIABLE ENERGY.

Our government is corrupt. Money talks. These companies will push for energy freedom and it will greatly benefit us all.

@ 04c915da:3dfbecc9

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.
