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

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

2024-12-26 07:02:59I just read this, and found it enlightening.
Jung... notes that intelligence can be seen as problem solving at an everyday level..., whereas creativity may represent problem solving for less common issues
Other studies have used metaphor creation as a creativity measure instead of divergent thinking and a spectrum of CHC components instead of just g and have found much higher relationships between creativity and intelligence than past studies
https://www.mdpi.com/2079-3200/3/3/59
I'm unusually intelligent (Who isn't?), but I'm much more creative, than intelligent, and I think that confuses people. The ability to apply intelligence, to solve completely novel problems, on the fly, is something IQ tests don't even claim to measure. They just claim a correlation.
Creativity requires taking wild, mental leaps out into nothingness; simply trusting that your brain will land you safely. And this is why I've been at the forefront of massive innovation, over and over, but never got rich off of it.
I'm a starving autist.
Zaps are the first time I've ever made money directly, for solving novel problems. Companies don't do this because there is a span of time between providing a solution and the solution being implemented, and the person building the implementation (or their boss) receives all the credit for the existence of the solution. At best, you can hope to get pawned off with a small bonus.
Nobody can remember who came up with the solution, originally, and that person might not even be there, anymore, and probably never filed a patent, and may have no idea that their idea has even been built. They just run across it, later, in a tech magazine or museum, and say, "Well, will you look at that! Someone actually went and built it! Isn't that nice!"
Universities at least had the idea of cementing novel solutions in academic papers, but that: 1) only works if you're an academic, and at a university, 2) is an incredibly slow process, not appropriate for a truly innovative field, 3) leads to manifestations of perverse incentives and biased research frameworks, coming from 'publish or perish' policies.
But I think long-form notes and zaps solve for this problem. #Alexandria, especially, is being built to cater to this long-suffering class of chronic underachievers. It leaves a written, public, time-stamped record of Clever Ideas We Have Had.
Because they are clever, the ideas. And we have had them.

2025-05-01 01:51:10Please respect Virginia Giuffre’s memory by refraining from asking about the circumstances or theories surrounding her passing.
Since Virginia Giuffre’s death, I’ve reflected on what she would want me to say or do. This piece is my attempt to honor her legacy.
When I first spoke with Virginia, I was struck by her unshakable hope. I had grown cynical after years in the anti-human trafficking movement, worn down by a broken system and a government that often seemed complicit. But Virginia’s passion, creativity, and belief that survivors could be heard reignited something in me. She reminded me of my younger, more hopeful self. Instead of warning her about the challenges ahead, I let her dream big, unburdened by my own disillusionment. That conversation changed me for the better, and following her lead led to meaningful progress.
Virginia was one of the bravest people I’ve ever known. As a survivor of Epstein, Maxwell, and their co-conspirators, she risked everything to speak out, taking on some of the world’s most powerful figures.
She loved when I said, “Epstein isn’t the only Epstein.” This wasn’t just about one man—it was a call to hold all abusers accountable and to ensure survivors find hope and healing.
The Epstein case often gets reduced to sensational details about the elite, but that misses the bigger picture. Yes, we should be holding all of the co-conspirators accountable, we must listen to the survivors’ stories. Their experiences reveal how predators exploit vulnerabilities, offering lessons to prevent future victims.
You’re not powerless in this fight. Educate yourself about trafficking and abuse—online and offline—and take steps to protect those around you. Supporting survivors starts with small, meaningful actions. Free online resources can guide you in being a safe, supportive presence.
When high-profile accusations arise, resist snap judgments. Instead of dismissing survivors as “crazy,” pause to consider the trauma they may be navigating. Speaking out or coping with abuse is never easy. You don’t have to believe every claim, but you can refrain from attacking accusers online.
Society also fails at providing aftercare for survivors. The government, often part of the problem, won’t solve this. It’s up to us. Prevention is critical, but when abuse occurs, step up for your loved ones and community. Protect the vulnerable. it’s a challenging but a rewarding journey.
If you’re contributing to Nostr, you’re helping build a censorship resistant platform where survivors can share their stories freely, no matter how powerful their abusers are. Their voices can endure here, offering strength and hope to others. This gives me great hope for the future.
Virginia Giuffre’s courage was a gift to the world. It was an honor to know and serve her. She will be deeply missed. My hope is that her story inspires others to take on the powerful.

@ 52b4a076:e7fad8bd
2025-04-28 00:48:57I have been recently building NFDB, a new relay DB. This post is meant as a short overview.
Regular relays have challenges
Current relay software have significant challenges, which I have experienced when hosting Nostr.land: - Scalability is only supported by adding full replicas, which does not scale to large relays. - Most relays use slow databases and are not optimized for large scale usage. - Search is near-impossible to implement on standard relays. - Privacy features such as NIP-42 are lacking. - Regular DB maintenance tasks on normal relays require extended downtime. - Fault-tolerance is implemented, if any, using a load balancer, which is limited. - Personalization and advanced filtering is not possible. - Local caching is not supported.
NFDB: A scalable database for large relays
NFDB is a new database meant for medium-large scale relays, built on FoundationDB that provides: - Near-unlimited scalability - Extended fault tolerance - Instant loading - Better search - Better personalization - and more.
Search
NFDB has extended search capabilities including: - Semantic search: Search for meaning, not words. - Interest-based search: Highlight content you care about. - Multi-faceted queries: Easily filter by topic, author group, keywords, and more at the same time. - Wide support for event kinds, including users, articles, etc.
Personalization

2025-05-21 11:09:22Issue 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!

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

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

2025-04-26 10:16:21O Contexto Legal Brasileiro e o Consentimento
No ordenamento jurídico brasileiro, o consentimento do ofendido pode, em certas circunstâncias, afastar a ilicitude de um ato que, sem ele, configuraria crime (como lesão corporal leve, prevista no Art. 129 do Código Penal). Contudo, o consentimento tem limites claros: não é válido para bens jurídicos indisponíveis, como a vida, e sua eficácia é questionável em casos de lesões corporais graves ou gravíssimas.
A prática de BDSM consensual situa-se em uma zona complexa. Em tese, se ambos os parceiros são adultos, capazes, e consentiram livre e informadamente nos atos praticados, sem que resultem em lesões graves permanentes ou risco de morte não consentido, não haveria crime. O desafio reside na comprovação desse consentimento, especialmente se uma das partes, posteriormente, o negar ou alegar coação.
A Lei Maria da Penha (Lei nº 11.340/2006)
A Lei Maria da Penha é um marco fundamental na proteção da mulher contra a violência doméstica e familiar. Ela estabelece mecanismos para coibir e prevenir tal violência, definindo suas formas (física, psicológica, sexual, patrimonial e moral) e prevendo medidas protetivas de urgência.
Embora essencial, a aplicação da lei em contextos de BDSM pode ser delicada. Uma alegação de violência por parte da mulher, mesmo que as lesões ou situações decorram de práticas consensuais, tende a receber atenção prioritária das autoridades, dada a presunção de vulnerabilidade estabelecida pela lei. Isso pode criar um cenário onde o parceiro masculino enfrenta dificuldades significativas em demonstrar a natureza consensual dos atos, especialmente se não houver provas robustas pré-constituídas.
Outros riscos:
Lesão corporal grave ou gravíssima (art. 129, §§ 1º e 2º, CP), não pode ser justificada pelo consentimento, podendo ensejar persecução penal.
Crimes contra a dignidade sexual (arts. 213 e seguintes do CP) são de ação pública incondicionada e independem de representação da vítima para a investigação e denúncia.
Riscos de Falsas Acusações e Alegação de Coação Futura
Os riscos para os praticantes de BDSM, especialmente para o parceiro que assume o papel dominante ou que inflige dor/restrição (frequentemente, mas não exclusivamente, o homem), podem surgir de diversas frentes:
- Acusações Externas: Vizinhos, familiares ou amigos que desconhecem a natureza consensual do relacionamento podem interpretar sons, marcas ou comportamentos como sinais de abuso e denunciar às autoridades.
- Alegações Futuras da Parceira: Em caso de término conturbado, vingança, arrependimento ou mudança de perspectiva, a parceira pode reinterpretar as práticas passadas como abuso e buscar reparação ou retaliação através de uma denúncia. A alegação pode ser de que o consentimento nunca existiu ou foi viciado.
- Alegação de Coação: Uma das formas mais complexas de refutar é a alegação de que o consentimento foi obtido mediante coação (física, moral, psicológica ou econômica). A parceira pode alegar, por exemplo, que se sentia pressionada, intimidada ou dependente, e que seu "sim" não era genuíno. Provar a ausência de coação a posteriori é extremamente difícil.
- Ingenuidade e Vulnerabilidade Masculina: Muitos homens, confiando na dinâmica consensual e na parceira, podem negligenciar a necessidade de precauções. A crença de que "isso nunca aconteceria comigo" ou a falta de conhecimento sobre as implicações legais e o peso processual de uma acusação no âmbito da Lei Maria da Penha podem deixá-los vulneráveis. A presença de marcas físicas, mesmo que consentidas, pode ser usada como evidência de agressão, invertendo o ônus da prova na prática, ainda que não na teoria jurídica.
Estratégias de Prevenção e Mitigação
Não existe um método infalível para evitar completamente o risco de uma falsa acusação, mas diversas medidas podem ser adotadas para construir um histórico de consentimento e reduzir vulnerabilidades:
- Comunicação Explícita e Contínua: A base de qualquer prática BDSM segura é a comunicação constante. Negociar limites, desejos, palavras de segurança ("safewords") e expectativas antes, durante e depois das cenas é crucial. Manter registros dessas negociações (e-mails, mensagens, diários compartilhados) pode ser útil.
-
Documentação do Consentimento:
-
Contratos de Relacionamento/Cena: Embora a validade jurídica de "contratos BDSM" seja discutível no Brasil (não podem afastar normas de ordem pública), eles servem como forte evidência da intenção das partes, da negociação detalhada de limites e do consentimento informado. Devem ser claros, datados, assinados e, idealmente, reconhecidos em cartório (para prova de data e autenticidade das assinaturas).
-
Registros Audiovisuais: Gravar (com consentimento explícito para a gravação) discussões sobre consentimento e limites antes das cenas pode ser uma prova poderosa. Gravar as próprias cenas é mais complexo devido a questões de privacidade e potencial uso indevido, mas pode ser considerado em casos específicos, sempre com consentimento mútuo documentado para a gravação.
Importante: a gravação deve ser com ciência da outra parte, para não configurar violação da intimidade (art. 5º, X, da Constituição Federal e art. 20 do Código Civil).
-
-
Testemunhas: Em alguns contextos de comunidade BDSM, a presença de terceiros de confiança durante negociações ou mesmo cenas pode servir como testemunho, embora isso possa alterar a dinâmica íntima do casal.
- Estabelecimento Claro de Limites e Palavras de Segurança: Definir e respeitar rigorosamente os limites (o que é permitido, o que é proibido) e as palavras de segurança é fundamental. O desrespeito a uma palavra de segurança encerra o consentimento para aquele ato.
- Avaliação Contínua do Consentimento: O consentimento não é um cheque em branco; ele deve ser entusiástico, contínuo e revogável a qualquer momento. Verificar o bem-estar do parceiro durante a cena ("check-ins") é essencial.
- Discrição e Cuidado com Evidências Físicas: Ser discreto sobre a natureza do relacionamento pode evitar mal-entendidos externos. Após cenas que deixem marcas, é prudente que ambos os parceiros estejam cientes e de acordo, talvez documentando por fotos (com data) e uma nota sobre a consensualidade da prática que as gerou.
- Aconselhamento Jurídico Preventivo: Consultar um advogado especializado em direito de família e criminal, com sensibilidade para dinâmicas de relacionamento alternativas, pode fornecer orientação personalizada sobre as melhores formas de documentar o consentimento e entender os riscos legais específicos.
Observações Importantes
- Nenhuma documentação substitui a necessidade de consentimento real, livre, informado e contínuo.
- A lei brasileira protege a "integridade física" e a "dignidade humana". Práticas que resultem em lesões graves ou que violem a dignidade de forma não consentida (ou com consentimento viciado) serão ilegais, independentemente de qualquer acordo prévio.
- Em caso de acusação, a existência de documentação robusta de consentimento não garante a absolvição, mas fortalece significativamente a defesa, ajudando a demonstrar a natureza consensual da relação e das práticas.
-
A alegação de coação futura é particularmente difícil de prevenir apenas com documentos. Um histórico consistente de comunicação aberta (whatsapp/telegram/e-mails), respeito mútuo e ausência de dependência ou controle excessivo na relação pode ajudar a contextualizar a dinâmica como não coercitiva.
-
Cuidado com Marcas Visíveis e Lesões Graves Práticas que resultam em hematomas severos ou lesões podem ser interpretadas como agressão, mesmo que consentidas. Evitar excessos protege não apenas a integridade física, mas também evita questionamentos legais futuros.
O que vem a ser consentimento viciado
No Direito, consentimento viciado é quando a pessoa concorda com algo, mas a vontade dela não é livre ou plena — ou seja, o consentimento existe formalmente, mas é defeituoso por alguma razão.
O Código Civil brasileiro (art. 138 a 165) define várias formas de vício de consentimento. As principais são:
Erro: A pessoa se engana sobre o que está consentindo. (Ex.: A pessoa acredita que vai participar de um jogo leve, mas na verdade é exposta a práticas pesadas.)
Dolo: A pessoa é enganada propositalmente para aceitar algo. (Ex.: Alguém mente sobre o que vai acontecer durante a prática.)
Coação: A pessoa é forçada ou ameaçada a consentir. (Ex.: "Se você não aceitar, eu termino com você" — pressão emocional forte pode ser vista como coação.)
Estado de perigo ou lesão: A pessoa aceita algo em situação de necessidade extrema ou abuso de sua vulnerabilidade. (Ex.: Alguém em situação emocional muito fragilizada é induzida a aceitar práticas que normalmente recusaria.)
No contexto de BDSM, isso é ainda mais delicado: Mesmo que a pessoa tenha "assinado" um contrato ou dito "sim", se depois ela alegar que seu consentimento foi dado sob medo, engano ou pressão psicológica, o consentimento pode ser considerado viciado — e, portanto, juridicamente inválido.
Isso tem duas implicações sérias:
-
O crime não se descaracteriza: Se houver vício, o consentimento é ignorado e a prática pode ser tratada como crime normal (lesão corporal, estupro, tortura, etc.).
-
A prova do consentimento precisa ser sólida: Mostrando que a pessoa estava informada, lúcida, livre e sem qualquer tipo de coação.
Consentimento viciado é quando a pessoa concorda formalmente, mas de maneira enganada, forçada ou pressionada, tornando o consentimento inútil para efeitos jurídicos.
Conclusão
Casais que praticam BDSM consensual no Brasil navegam em um terreno que exige não apenas confiança mútua e comunicação excepcional, mas também uma consciência aguçada das complexidades legais e dos riscos de interpretações equivocadas ou acusações mal-intencionadas. Embora o BDSM seja uma expressão legítima da sexualidade humana, sua prática no Brasil exige responsabilidade redobrada. Ter provas claras de consentimento, manter a comunicação aberta e agir com prudência são formas eficazes de se proteger de falsas alegações e preservar a liberdade e a segurança de todos os envolvidos. Embora leis controversas como a Maria da Penha sejam "vitais" para a proteção contra a violência real, os praticantes de BDSM, e em particular os homens nesse contexto, devem adotar uma postura proativa e prudente para mitigar os riscos inerentes à potencial má interpretação ou instrumentalização dessas práticas e leis, garantindo que a expressão de sua consensualidade esteja resguardada na medida do possível.
Importante: No Brasil, mesmo com tudo isso, o Ministério Público pode denunciar por crime como lesão corporal grave, estupro ou tortura, independente de consentimento. Então a prudência nas práticas é fundamental.

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

2025-05-21 00:24:36Yeah, 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.

2025-05-21 10:52:12Dear readers,
“The direct use of force is such a poor solution to any problem, it is generally employed only by small children and large nations.” — David Friedman
What If we could enforce promises without force?
David Friedman, in his book The Machinery of Freedom, tosses out a pretty wild idea: that people can build systems of cooperation and justice without needing a government at all. These systems rely on voluntary agreements, social reputation, and mutual incentives. In such a world, contracts hold value because honoring a promise brings greater rewards than breaking it.
From Friedman to Bitcoin
https://i.ytimg.com/vi/e8zsFTV94bw/maxresdefault.jpg
This vision shaped the thinking behind Angor, a funding tool built on Bitcoin. Friedman’s ideas showed that systems of cooperation could work without central authority, and Bitcoin now provides the foundation to build them. It records transactions in a public and tamper-proof way. With features like Taproot, people can set clear rules for funding and accountability. Angor uses these tools to help founders and backers create agreements that are transparent and easy to verify.
The result is a new kind of marketplace where follow-through is visible, and reputation becomes a real asset. Instead of relying on enforcement from above, trust is earned through action and built into the system itself.
What happens after the project succeeds?
One important question kept returning throughout our work: what happens after a project succeeds? The founder raises the funds, delivers the product, and begins earning revenue. What mechanism ensures that revenue is shared as promised? How can investors protect their interests in an environment that relies on voluntary structure rather than external authority?
To explore possible answers, we looked at how libertarian thinkers approach contracts in stateless systems.
How libertarian thinkers approach contracts without the state?
Friedman, along with other libertarian thinkers like Murray Rothbard and Bruce Benson, describes voluntarily created legal systems where people make binding agreements and use private mechanisms to enforce them. These mechanisms include:
• Reputational risk • Collateralized performance • Community arbitration • Decentralized insurance
Such tools can replace state-backed enforcement when trust is earned and incentives are aligned.
If founders are anonymous:
When a founder chooses to remain pseudonymous, legal enforcement is not available. In this case, the agreement between the founder and investor can rely on cryptographic mechanisms such as performance bonds, revenue proofs, and public reputation systems.
- Performance Bonds
• Founders deposit additional Bitcoin into a separate, time-locked contract. As they meet revenue-sharing milestones, they are allowed to unlock specific portions of this bond.
• If a revenue allocation is missed or a deadline passes without fulfillment, the contract redirects the bond to investors through a Taproot clause i.e. a feature in Bitcoin that lets you set up ‘if-this-then-that’ rules directly into a transaction, but privately. This creates a clear and automatic consequence, reinforcing accountability through financial incentives.
- Revenue Proofs and Oracles
• Most founders, especially those running small businesses like cafes, games, or services, do not earn revenue in Bitcoin. Their income flows through fiat systems, which means automatic on-chain revenue streaming is not an option. The only way to maintain transparency is to prove income after the fact. This starts with exporting a sales report from a platform such as Stripe, Revolut, or a point-of-sale system. The founder hashes the file and posts that hash to the Bitcoin blockchain as a timestamped public reference.
• An oracle plays the role of a neutral verifier. This could be a trusted accountant or an observer chosen by the investor community. Their job is simple: compare the actual report with the hash recorded on-chain. If the data matches, the oracle signs a message that triggers the revenue-share payout using a Discreet Log Contract (DLC).
A DLC is similar to a smart contract, but built for Bitcoin. It allows two parties to agree on a specific outcome, such as how much revenue was made, and only releases funds when that outcome is confirmed by the oracle.
This process does not depend on central enforcement. Instead, it works through mutual agreement and the oracle’s reputation, or any collateral they may have provided in advance.
- Reputation as collateral
• Every revenue-share payout is recorded on the Bitcoin blockchain, making it publicly visible and verifiable. Community-run indexers can scan the chain and track whether a founder consistently delivers payments on time. This performance history is then summarized into what is known as a “contract streak,” which refers to the number of consecutive payouts completed without delay.
• These streaks are published as signed events through protocols like Nostr, allowing anyone to verify a founder’s track record. A strong, uninterrupted streak builds credibility and can improve the chances of raising funds for future projects. In contrast, a broken streak signals risk, which discourages new investment and reduces access to support from the Angor community.
If founders are public:
When a founder uses a real identity, the parties can combine legal agreements with on-chain contracts. These hybrid arrangements allow for tools like enforceable smart contracts, voluntary arbitration, and potentially community-backed insurance.
- Legally binding smart contracts
• This type of agreement formally identifies the founder’s legal entity and clearly links it to specific Taproot addresses used in the project. It outlines the rules for revenue sharing, describes what constitutes a breach, and specifies how disputes should be resolved. Because it is a formal legal document, it can be enforced in any relevant jurisdiction where the founder has a presence or assets.
- Private arbitration
• During the contract setup, both parties can agree to a neutral arbitrator who will step in if a dispute arises. If a revenue payout is delayed or missed, the arbitrator reviews all relevant data, including on-chain records, oracle confirmations, and supporting documentation. Based on this evidence, the arbitrator issues a decision that determines whether funds should be released, held, or redirected. This method provides a clear resolution process without involving courts, while still maintaining a fair and structured outcome.
- Equity sharing and traditional securities
• When founders are publicly identified and operating under a registered entity, they can also offer equity in the company as part of the funding arrangement. This can take the form of direct share issuance, convertible notes, or tokenized equity, depending on jurisdictional frameworks and investor preferences.
While Angor does not facilitate equity transfers directly, the on-chain agreement can reference these arrangements clearly. Investors may receive shares documented in a cap table, with accompanying legal agreements that govern dividend rights, voting power, or exit terms.
This method provides a more conventional form of investor alignment and is often well-understood by experienced backers. It can also be combined with on-chain revenue-sharing mechanisms to create hybrid models that balance transparency with long-term equity value.
Final Thought: Alignment Over Authority
The ideas in The Machinery of Freedom show how people can build cooperative systems without relying on centralized authority. Angor puts those ideas into action by applying them to decentralized crowdfunding. Each campaign becomes a contract. Each payout becomes a public signal of integrity. Reputation is built over time, through visible and verifiable performance.
This approach shifts enforcement from force to alignment. It rewards honesty and transparency while making misuse costly. By designing systems where trust is earned through action and recorded on-chain, we move toward a more resilient model of funding. This model is grounded in consent, shaped by shared incentives, and supported by the open logic of Bitcoin.
Bitcoin itself works this way. Miners follow the rules not because they are told to, but because breaking them wastes energy, time, and opportunity. The cost of cheating is built into the system. Angor adopts the same principle: integrity is not enforced from above, it is embedded in the architecture.
If you are building on Angor or exploring similar ideas, reach out. The tools are evolving, and the community is growing.

@ e3ba5e1a:5e433365
2025-04-15 11:03:15Prelude
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:
- Perfect is the enemy of the good
- 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.

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 .

2025-05-20 15:53:48This 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.

2025-02-09 20:34:15I didn’t set out to become an enemy of the world’s richest man, but I seem to have managed it all the same. Until this moment, I’ve resisted describing my falling out with Elon Musk in much detail, but as the man’s cultural influence has metastasized—and he continues to spread lies about me on the social media platform that he owns (Twitter/X)—it seems only appropriate to set the record straight. I know that it annoys many in my audience to see me defend myself against attacks that they recognize to be spurious, but they might, nevertheless, find the details of what happened with Elon interesting.
Of all the remarkable people I’ve met, Elon is probably the most likely to remain a world-historical figure—despite his best efforts to become a clown. He is also the most likely to squander his ample opportunities to live a happy life, ruin his reputation and most important relationships, and produce lasting harm across the globe. None of this was obvious to me when we first met, and I have been quite amazed at Elon’s evolution, both as a man and as an avatar of chaos. The friend I remember did not seem to hunger for public attention. But his engagement with Twitter/X transformed him—to a degree seldom seen outside of Marvel movies or Greek mythology. If Elon is still the man I knew, I can only conclude that I never really knew him.
When we first met, Elon wasn’t especially rich or famous. In fact, I recall him teetering on the brink of bankruptcy around 2008, while risking the last of his previous fortune to make payroll at Tesla. At the time, he was living off loans from his friends Larry and Sergey. Once Elon became truly famous, and his personal wealth achieved escape velocity, I was among the first friends he called to discuss his growing security concerns. I put him in touch with Gavin de Becker, who provided his first bodyguards, and recommended other changes to his life. We also went shooting on at least two occasions with Scott Reitz, the finest firearms instructor I’ve ever met. It is an ugly irony that Elon’s repeated targeting of me on Twitter/X has increased my own security concerns. He understands this, of course, but does not seem to care.
So how did we fall out? Let this be a cautionary tale for any of Elon’s friends who might be tempted to tell the great man something he doesn’t want to hear:
(1.) When the SARS-CoV-2 virus first invaded our lives in March of 2020, Elon began tweeting in ways that I feared would harm his reputation. I also worried that his tweets might exacerbate the coming public-health emergency. Italy had already fallen off a cliff, and Elon shared the following opinion with his tens of millions of fans :
the coronavirus panic is dumb
As a concerned friend, I sent him a private text:
Hey, brother— I really think you need to walk back your coronavirus tweet. I know there’s a way to parse it that makes sense (“panic” is always dumb), but I fear that’s not the way most people are reading it. You have an enormous platform, and much of the world looks to you as an authority on all things technical. Coronavirus is a very big deal, and if we don’t get our act together, we’re going to look just like Italy very soon. If you want to turn some engineers loose on the problem, now would be a good time for a breakthrough in the production of ventilators...
(2.) Elon’s response was, I believe, the first discordant note ever struck in our friendship:
Sam, you of all people should not be concerned about this.
He included a link to a page on the CDC website, indicating that Covid was not even among the top 100 causes of death in the United States. This was a patently silly point to make in the first days of a pandemic.
We continued exchanging texts for at least two hours. If I hadn’t known that I was communicating with Elon Musk, I would have thought I was debating someone who lacked any understanding of basic scientific and mathematical concepts, like exponential curves.
(3.) Elon and I didn’t converge on a common view of epidemiology over the course of those two hours, but we hit upon a fun compromise: A wager. Elon bet me $1 million dollars (to be given to charity) against a bottle of fancy tequila ($1000) that we wouldn’t see as many as 35,000 cases of Covid in the United States (cases, not deaths). The terms of the bet reflected what was, in his estimation, the near certainty (1000 to 1) that he was right. Having already heard credible estimates that there could be 1 million deaths from Covid in the U.S. over the next 12-18 months (these estimates proved fairly accurate), I thought the terms of the bet ridiculous—and quite unfair to Elon. I offered to spot him two orders of magnitude: I was confident that we’d soon have 3.5 million cases of Covid in the U.S. Elon accused me of having lost my mind and insisted that we stick with a ceiling of 35,000.
(4.) We communicated sporadically by text over the next couple of weeks, while the number of reported cases grew. Ominously, Elon dismissed the next batch of data reported by the CDC as merely presumptive—while confirmed cases of Covid, on his account, remained elusive.
(5.) A few weeks later, when the CDC website finally reported 35,000 deaths from Covid in the U.S. and 600,000 cases, I sent Elon the following text:
Is (35,000 deaths + 600,000 cases) > 35,000 cases?
(6.) This text appears to have ended our friendship. Elon never responded, and it was not long before he began maligning me on Twitter for a variety of imaginary offenses. For my part, I eventually started complaining about the startling erosion of his integrity on my podcast, without providing any detail about what had transpired between us.
(7.) At the end of 2022, I abandoned Twitter/X altogether, having recognized the poisonous effect that it had on my life—but also, in large part, because of what I saw it doing to Elon. I’ve been away from the platform for over two years, and yet Elon still attacks me. Occasionally a friend will tell me that I’m trending there, and the reasons for this are never good. As recently as this week, Elon repeated a defamatory charge about my being a “hypocrite” for writing a book in defense of honesty and then encouraging people to lie to keep Donald Trump out of the White House. Not only have I never advocated lying to defeat Trump (despite what that misleading clip from the Triggernometry podcast might suggest to naive viewers), I’ve taken great pains to defend Trump from the most damaging lie ever told about him. Elon knows this, because we communicated about the offending clip when it first appeared on Twitter/X. However, he simply does not care that he is defaming a former friend to hundreds of millions of people—many of whom are mentally unstable. On this occasion, he even tagged the incoming president of the United States.
All of this remains socially and professionally awkward, because Elon and I still have many friends in common. Which suggests the terms of another wager that I would happily make, if such a thing were possible—and I would accept 1000 to 1 odds in Elon’s favor:
I bet that anyone who knows us both knows that I am telling the truth.
Everyone close to Elon must recognize how unethical he has become, and yet they remain silent. Their complicity is understandable, but it is depressing all the same. These otherwise serious and compassionate people know that when Elon attacks private citizens on Twitter/X—falsely accusing them of crimes or corruption, celebrating their misfortunes—he is often causing tangible harm in their lives. It’s probably still true to say that social media “isn’t real life,” until thousands of lunatics learn your home address.
A final absurdity in my case, is that several of the controversial issues that Elon has hurled himself at of late—and even attacked me over—are ones we agree about. We seem to be in near total alignment on immigration and the problems at the southern border of the U.S. We also share the same concerns about what he calls “the woke mind virus.” And we fully agree about the manifest evil of the so-called “grooming-gangs scandal” in the U.K. The problem with Elon, is that he makes no effort to get his facts straight when discussing any of these topics, and he regularly promotes lies and conspiracy theories manufactured by known bad actors, at scale. (And if grooming were really one of his concerns, it’s strange that he couldn’t find anything wrong with Matt Gaetz.)
Elon and I even agree about the foundational importance of free speech. It’s just that his approach to safeguarding it—amplifying the influence of psychopaths and psychotics, while deplatforming real journalists and his own critics; or savaging the reputations of democratic leaders, while never saying a harsh word about the Chinese Communist Party—is not something I can support. The man claims to have principles, but he appears to have only moods and impulses.
Any dispassionate observer of Elon’s behavior on Twitter/X can see that there is something seriously wrong with his moral compass, if not his perception of reality. There is simply no excuse for a person with his talents, resources, and opportunities to create so much pointless noise. The callousness and narcissism conveyed by his antics should be impossible for his real friends to ignore—but they appear to keep silent, perhaps for fear of losing access to his orbit of influence.
Of course, none of this is to deny that the tens of thousands of brilliant engineers Elon employs are accomplishing extraordinary things. He really is the greatest entrepreneur of our generation. And because of the businesses he’s built, he will likely become the world’s first trillionaire—perhaps very soon. Since the election of Donald Trump in November, Elon’s wealth has grown by around $200 billion. That’s nearly $3 billion a day (and over $100 million an hour). Such astonishing access to resources gives Elon the chance—and many would argue the responsibility—to solve enormous problems in our world.
So why spend time spreading lies on X?

2025-05-21 10:30:07„Európának a tettek mezejére kell lépnie a nukleáris energia támogatásában” – mondja a brüsszeli iparági csoport új vezetője
A cikk fő témája, hogy az európai nukleáris ipar új vezetője, Emmanuel Brutin (Nucleareurope), nagyobb elkötelezettséget vár el az Európai Bizottságtól a nukleáris energia támogatásában. Bár pozitív jelek mutatkoznak a nukleáris energia iránti nyitottság terén, Brutin szerint a gyakorlatban még mindig jelentős akadályok vannak, például a finanszírozási forrásokhoz való hozzáférésben és a projektengedélyezések lassúságában.
Főbb pontok:
- Politikai nyitottság, de gyakorlati akadályok: Az EU-ban nőtt a nukleáris energia elismerése, például bekerült a fenntartható befektetési taxonómiába és a Net-Zero Industry Act-be. Ugyanakkor a nukleáris energia továbbra is kizárt több fontos finanszírozási eszközből, mint az InvestEU vagy a Just Transition Fund.
- Technológiai semlegesség szükségessége: Brutin hangsúlyozza, hogy az EU-nak nemcsak nem szabad hátráltatnia a nukleáris energiát, hanem aktívan támogatnia is kellene, különösen a Clean Industrial Deal és az Affordable Energy Action Plan keretében.
- Finanszírozás és engedélyezés: A nukleáris ágazat számára kulcsfontosságú a finanszírozáshoz való jobb hozzáférés, mivel a beruházások tőkeigényesek. Brutin szerint gyorsítani kellene a nukleáris projektek engedélyezését, és lazítani az állami támogatási szabályokon.
- Stratégiai jelentőség: Európa teljes nukleáris értéklánccal rendelkezik, ami stratégiai autonómiát jelent, különösen a jelenlegi geopolitikai környezetben.
- Új PINC dokumentum: Nyáron várható a frissített PINC (Illustrative Nuclear Programme), amelynek konkrét lépéseket kell tartalmaznia a nukleáris beruházások támogatására.
- Iparági igények: Az energiaintenzív iparágak (pl. acél, cement) számára nem az energiaforrás típusa számít, hanem a megbízható, olcsó és dekarbonizált villamosenergia-ellátás.
- Tanulás a múlt hibáiból: Brutin elismeri, hogy a nukleáris projektek Európában gyakran szenvedtek késésektől és költségtúllépésektől, de az iparág dolgozik ezek megoldásán.

2025-01-05 03:32:27EVERYDAY STACKING GUIDE
Let me break it down for you: stacking sats is about building your Bitcoin stash little by little. You do not need to make some massive play or wait for the perfect opportunity. It is about finding simple, steady ways to add to your stack, no matter what your situation looks like. And the best part? There are so many ways to do it, whether you are creating something, connecting with folks directly, or just using tools that reward you. Let us dive into how you can stack sats consistently, keeping it decentralized and peer-to-peer whenever possible.
You have got platforms like Stacker News where you can earn sats just by being part of the conversation. Think of it as Bitcoin’s answer to Reddit. You share something valuable, comment on posts, or just engage with the community, and next thing you know, you have got some sats coming your way. It is simple, and it is steady. Plus, it feels good to know your thoughts and contributions are being rewarded.
Then there is Nostr, a decentralized social platform that is making waves. It is built to connect people directly, and it ties in Bitcoin through the Lightning Network. The coolest thing? You can get tipped, or “zapped,” for your posts, notes, or anything you put out there. This is not about big corporations taking a cut; it is people showing love directly. Share your ideas, your art, your insights, and watch your stack grow while connecting with a global community.
Now, let us talk about Fold. It is a little different but still fun. You spin their rewards wheel every day, and you will earn a few sats. Sometimes it is a little, sometimes it is more, but it all adds up. If you are using their Bitcoin rewards debit card for your regular spending, you are earning even more. Sure, it is not 100 percent decentralized, but it is an easy way to stack sats while handling your everyday purchases.
For creators, platforms like Zap.Stream are opening doors. Imagine streaming your work, whether it is music, art, teaching, or something else, and getting paid directly in Bitcoin by your audience. No middlemen, no fuss. It is all about connecting directly with the people who support you and earning sats in real time.
And do not forget about selling something for Bitcoin. Whether it is handmade crafts, digital products, or your services, there is always a way to find buyers who want to pay in sats. Platforms that focus on Bitcoin marketplaces make it easier to connect with those folks. Plus, it is a true peer-to-peer exchange, keeping it aligned with the decentralized spirit of Bitcoin.
If you are freelancing, there are options to get paid in Bitcoin directly. Whether you are designing, coding, writing, or consulting, there are platforms that let you bypass the banks and get your payment straight into your wallet. It is quick, efficient, and keeps you in control of your money.
And let us talk about the small, passive ways to stack sats. Cashback apps like Lolli let you earn Bitcoin on everyday purchases. It might not be a huge amount, but those little bits add up over time. If you are already spending the money, why not get some sats back for it?
The real key here is consistency. Set a goal for yourself, whether it is adding sats daily or weekly, and stick to it. Even if it is just a few hundred sats here and there, it is progress. Those small steps add up over time and can turn into something meaningful.
Why focus on decentralized and peer-to-peer methods? Because that is what Bitcoin is all about. It is about staying true to the values of self-sovereignty and financial freedom. By avoiding centralized systems, you are not just stacking sats; you are strengthening the Bitcoin ecosystem itself.
Stacking sats is not about getting rich overnight. It is a journey. It is about building your stash, supporting the Bitcoin movement, and claiming your financial independence bit by bit. Whether it is through sharing content, selling products, or using new platforms, the mission stays the same: keep adding to your stack, little by little. And remember, every sat counts.

2025-05-16 19:23:58This article was originally part of the sermon of Plebchain Radio Episode 110 (May 2, 2025) that nostr:nprofile1qyxhwumn8ghj7mn0wvhxcmmvqyg8wumn8ghj7mn0wd68ytnvv9hxgqpqtvqc82mv8cezhax5r34n4muc2c4pgjz8kaye2smj032nngg52clq7fgefr and I did with nostr:nprofile1qythwumn8ghj7ct5d3shxtnwdaehgu3wd3skuep0qyt8wumn8ghj7ct4w35zumn0wd68yvfwvdhk6tcqyzx4h2fv3n9r6hrnjtcrjw43t0g0cmmrgvjmg525rc8hexkxc0kd2rhtk62 and nostr:nprofile1qyxhwumn8ghj7mn0wvhxcmmvqyg8wumn8ghj7mn0wd68ytnvv9hxgqpq4wxtsrj7g2jugh70pfkzjln43vgn4p7655pgky9j9w9d75u465pqahkzd0 of the nostr:nprofile1qythwumn8ghj7ct5d3shxtnwdaehgu3wd3skuep0qyt8wumn8ghj7etyv4hzumn0wd68ytnvv9hxgtcqyqwfvwrccp4j2xsuuvkwg0y6a20637t6f4cc5zzjkx030dkztt7t5hydajn
Listen to the full episode here:
<https://fountain.fm/episode/Ln9Ej0zCZ5dEwfo8w2Ho>
Bitcoin has always been a narrative revolution disguised as code. White paper, cypherpunk lore, pizza‑day legends - every block is a paragraph in the world’s most relentless epic. But code alone rarely converts the skeptic; it’s the camp‑fire myth that slips past the prefrontal cortex and shakes hands with the limbic system. People don’t adopt protocols first - they fall in love with protagonists.
Early adopters heard the white‑paper hymn, but most folks need characters first: a pizza‑day dreamer; a mother in a small country, crushed by the cost of remittance; a Warsaw street vendor swapping złoty for sats. When their arcs land, the brain releases a neurochemical OP_RETURN which says, “I belong in this plot.” That’s the sly roundabout orange pill: conviction smuggled inside catharsis.
That’s why, from 22–25 May in Warsaw’s Kinoteka, the Bitcoin Film Fest is loading its reels with rebellion. Each documentary, drama, and animated rabbit‑hole is a stealth wallet, zipping conviction straight into the feels of anyone still clasped within the cold claw of fiat. You come for the plot, you leave checking block heights.
Here's the clip of the sermon from the episode:

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

2025-05-21 08:52:36ปี 2568 ตลาดคริปโตยังคงเต็มไปด้วยความร้อนแรงและโอกาส Bitcoin พุ่งแตะ 106,595.5 ดอลลาร์ (ณ วันที่ 21 พ.ค. 2568) ขณะที่เหรียญมีมอย่าง KPEPE ก็กลายเป็นที่จับตามองของเหล่านักลงทุนรายใหญ่ แต่ท่ามกลางกระแสความร้อนแรง คำถามสำคัญยังคงอยู่: ตลาดคริปโตอยู่ช่วงไหนของวัฏจักร? และโอกาสใหญ่กำลังมาหรือใกล้จบลงแล้ว?
หนึ่งในเสียงที่ดังที่สุดในชุมชนคริปโตตอนนี้คือชื่อที่หลายคนอาจยังไม่รู้จักแน่ชัด – James Wynn เขาโพสต์ข้อความเมื่อวันที่ 31 มีนาคม 2568 ว่า
“The best is yet to come.” หรือ “สิ่งที่ดีที่สุดยังมาไม่ถึง” – คำพูดที่จุดประกายความหวังในชุมชนนักเทรดทั่วโลก
แม้เขาจะถูกยกย่องว่าเป็น “วาฬคริปโต” จากการถือครองมูลค่ามหาศาล แต่ในความเป็นจริง เรายังไม่รู้ว่าเขาคือใคร – ชื่อ James Wynn อาจเป็นเพียงนามแฝง หรือ persona บนโลกออนไลน์ก็เป็นได้
ในบทความนี้ เราจะวิเคราะห์มุมมองของเขาอย่างมีวิจารณญาณ พร้อมแนะแนวทางที่นักเทรดควรเตรียมตัวเพื่อคว้าโอกาสในช่วงขาขึ้นนี้
ภาพรวมตลาดคริปโตในปี 2568 ปีนี้ถือเป็นช่วงขาขึ้นที่เกิดจากหลายปัจจัยสำคัญ:
การอนุมัติ Bitcoin Spot ETFs ในสหรัฐฯ
การเข้ารับตำแหน่งของ Donald Trump พร้อมนโยบายที่เป็นมิตรต่อคริปโต เช่น การผลักดันให้ Bitcoin เป็นสินทรัพย์สำรองของชาติ
ปัจจัยเหล่านี้ได้ดึงดูดทั้งนักลงทุนรายย่อยและสถาบันเข้าสู่ตลาด ส่งผลให้ราคาของ BTC และเหรียญมีมอย่าง KPEPE พุ่งสูงขึ้นอย่างรวดเร็ว สะท้อนถึงโมเมนตัมที่ยังคงแข็งแกร่ง
มุมมองจาก ‘James Wynn’: ปลายวัฏจักร? หรือแค่เริ่มต้น? แม้จะไม่มีใครรู้แน่ชัดว่า James Wynn คือใคร แต่เขากลายเป็นบุคคลที่มีอิทธิพลในชุมชนคริปโตจากการเปิดเผยมุมมองที่เฉียบคมและพอร์ตการลงทุนขนาดใหญ่
เขาโพสต์ไว้ว่า
“ถ้าใครคิดว่าเราอยู่ท้ายวัฏจักรแล้ว คุณคิดผิด”
โดยให้เหตุผลหลัก 3 ข้อ:
การพุ่งขึ้นของราคาส่วนใหญ่เกิดจาก ข่าวดีภายนอก เช่น ETF ยังไม่ใช่ "กระแสล้นตลาด"
นโยบายรัฐบาล Trump ส่งผลเชิงจิตวิทยาเชิงบวกต่อทั้งนักลงทุนและตลาด
ยังไม่เกิด Altcoin Season หรืออารมณ์ตลาดช่วง “Euphoria” ตามแผนภาพ Psychology of a Market Cycle
เขาประเมินว่าตลาดน่าจะอยู่ช่วง “Optimism → Thrill” ซึ่งเป็นช่วงกลางของวัฏจักรที่นักลงทุนเริ่มตื่นเต้น แต่ยังไม่ถึงจุดสูงสุด
เขาเป็นใคร? วาฬตัวจริงหรือบุคคลลึกลับ? แม้ James Wynn จะได้รับความสนใจอย่างมาก แต่ตัวตนของเขายังคลุมเครือ:
ไม่มีข้อมูลยืนยันตัวตนชัดเจน
ไม่รู้ว่าเขาเป็นบุคคล กลุ่ม หรือองค์กร
ใช้นามแฝงออนไลน์ และบัญชีเทรดที่ระบุไว้ไม่ผูกกับตัวตนจริง
ถึงอย่างนั้น พฤติกรรมการลงทุนของเขาก็ไม่ธรรมดา:
Long BTC-USD ด้วยเลเวอเรจ 40x กว่า 5,200 BTC (มูลค่ากว่า 546 ล้านดอลลาร์)
Long KPEPE-USD ด้วยเลเวอเรจ 10x มูลค่ากว่า 32.8 ล้านดอลลาร์
รวมกำไรจากการเทรดกว่า 20.2 ล้านดอลลาร์ (ราว 687 ล้านบาท)
ใช้แพลตฟอร์ม Hyperliquid และแสดงจุดยืนต่อต้าน CEX บางแห่งอย่าง Bybit ที่เขาเคยกล่าวหาว่ามีการ manipulate ตลาด
สิ่งที่น่าสนใจคือ Wynn มักจะลดตำแหน่งและล็อกกำไรอย่างเป็นระบบ เช่น วันที่ 20 พ.ค. 2568 เขาลดตำแหน่ง BTC ลง 1,142 BTC และถอน USDC กลับวอลเล็ตส่วนตัว – สะท้อนถึงการบริหารความเสี่ยงที่รอบคอบ
แนวทางสำหรับนักเทรด: ถ้า "สิ่งที่ดีที่สุด" ยังมาไม่ถึง... หากมุมมองของ Wynn ถูกต้อง และตลาดยังไม่ถึงจุดสูงสุด ต่อไปนี้คือตัวอย่างแนวทางที่นักเทรดควรพิจารณา:
🔹 วางแผนรับ pullback: หากอยู่ในช่วง "Thrill" ตลาดอาจมีการพักตัวชั่วคราว – เป็นโอกาสในการ “ซื้อซ้ำ” ก่อนเข้าสู่จุดพีค
🔹 จับตา altcoin season: การที่เหรียญมีมอย่าง KPEPE พุ่งขึ้น อาจเป็นสัญญาณล่วงหน้าของ Altcoin Season ที่กำลังจะเริ่ม – เตรียมลิสต์เหรียญที่มีศักยภาพ
🔹 เน้นการบริหารความเสี่ยง: ใช้ stop-loss และเลเวอเรจอย่างระมัดระวัง อย่าลืมว่าวัฏจักรคริปโตสามารถเปลี่ยนแปลงอย่างรวดเร็ว
🔹 ติดตามความเคลื่อนไหวของวาฬ (แม้จะไม่รู้ว่าเขาคือใคร): เช่น ที่อยู่กระเป๋า 0x5078C2FbeA2B2aD61bcB40BC0233E5Ce56EDb6 ซึ่งเชื่อว่าเป็นของ Wynn – การเคลื่อนไหวของกระเป๋านี้อาจบ่งชี้แนวโน้มตลาดล่วงหน้า
สรุป แม้เราจะยังไม่รู้แน่ชัดว่า James Wynn คือใคร หรือแม้กระทั่งเขามีอยู่จริงหรือไม่ แต่คำพูดของเขาก็สอดคล้องกับทิศทางตลาดในปัจจุบันที่ยังคงอยู่ในขาขึ้น
“The best is yet to come.” – ถ้าเขาพูดถูก โอกาสที่ดีที่สุดในตลาดคริปโตปี 2568 ก็ยังไม่มาถึง
นักเทรดควร:
ติดตามสัญญาณตลาดอย่างรอบคอบ
จัดพอร์ตให้พร้อมสำหรับการเปลี่ยนแปลง
และที่สำคัญ — อย่าหลงกระแส โดยไม่มีแผนรองรับ
วาฬที่แท้จริงอาจไม่มีชื่อเสียง… และนั่นแหละคือสิ่งที่ทำให้พวกเขาน่าจับตายิ่งกว่าใคร

2025-04-07 13:17:50What is Growth Engineering? Before we start: if you’ve already filled out the What is your tech stack? survey: thank you! If you’ve not done so, your help will be greatly appreciated. It takes 5-15 minutes to complete. Those filling out will receive results before anyone else, and additional analysis from myself and Elin. Fill out this survey here.**
npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m
Growth engineering was barely known a decade ago, but today, most scaleups and many publicly traded tech companies have dedicated growth teams staffed by growth engineers. However, some software engineers are still suspicious of this new area because of its reputation for hacky code with little to no code coverage.
For this reason and others, I thought it would be interesting to learn more from an expert who can tell us all about the practicalities of this controversial domain. So I turned to Alexey Komissarouk, who’s been in growth engineering since 2016, and was in charge of it at online education platform, MasterClass. These days, Alexey lives in Tokyo, Japan, where he advises on growth engineering and teaches the Growth Engineering course at Reforge.
In today’s deep dive, Alexey covers:
- What is Growth Engineering? In the simplest terms: writing code to help a company make more money. But there are details to consider: like the company size where it makes sense to have a dedicated team do this.
- What do Growth Engineers work on? Business-facing work, empowerment and platform work are the main areas.
- Why Growth Engineers move faster than Product Engineers. Product Engineers ship to build: Growth Engineers ship to learn. Growth Engineers do take shortcuts that would make no sense when building for longevity – doing this on purpose.
- Tech stack. Common programming languages, monitoring and oncall, feature flags and experimentation, product analytics, review apps, and more.
- What makes a good Growth Engineer? Curiosity, “build to learn” mindset and a “Jack of all trades” approach.
- Where do Growth Engineers fit in? Usually part of the engineering department, either operating as with an “owner” or a “hitchiker” model.
- Becoming a Growth Engineer. A great area if you want to eventually become a founder or product manager – but even if not, it can accelerate your career growth. Working in Growth forces you to learn more about the business.
With that, it’s over to Alexey:
I’ll never forget the first time I made my employer a million dollars.
I was running a push notification A/B test for meal delivery startup Sprig, trying to boost repeat orders.
A push notification similar to what we tested to boost repeat orders
Initial results were unpromising; the push notification was not receiving many opens. Still, I wanted to be thorough: before concluding the idea was a failure, I wrote a SQL query to compare order volume for subsequent weeks between customers in test vs control.
The SQL used to figure out the push notification’s efficiency
As it turned out, our test group “beat” the control group by around 10%:
‘review_5_push’ was the new type of push notification. Roughly the same amount of users clicked it, but they placed 10% more in orders
I plugged the numbers into a significance calculator, which showed it was statistically significant – or “stat-sig” – and therefore highly unlikely to be a coincidence. This meant we had a winner on our hands! But how meaningful was it, really, and what would adding the push notification mean for revenue, if rolled out to 100% of users?
It turned out this experiment created an additional $1.5 million dollars, annually, with just one push notification. Wow!
I was hooked. Since that day, I've shipped hundreds of experimental “winners” which generated hundreds of millions of incremental revenue for my employers. But you never forget the first one. Moments like this is what growth engineering is all about.
1. What is Growth Engineering?
Essentially, growth engineering is the writing of code to make a company money. Of course, all code produced by a business on some level serves this purpose, but while Product Engineers focus on creating a Product worth paying for, Growth Engineers instead focus on making that good product have a good business. To this end, they focus on optimizing and refining key parts of the customer journey, such as:
- Getting more people to consider the product
- Converting them into paying customers
- Keeping them as customers for longer, and spending more
What kinds of companies employ Growth Engineers? Places you’ve heard of, like Meta, LinkedIn, DoorDash, Coinbase, and Dropbox, are some of the ones I’ve had students from. There’s also OpenAI, Uber, Tiktok, Tinder, Airbnb, Pinterest… the list of high-profile companies goes on. Most newer public consumer companies you’ve heard have a growth engineering org, too.
Typically, growth engineering orgs are started by companies at Series B stage and beyond, so long as they are selling to either consumers or businesses via SaaS. These are often places trying to grow extremely fast, and have enough software engineers that some can focus purely on growth. Before the Series B stage, a team is unlikely to be ready for growth for various reasons; likely that it hasn’t found product-market fit, or has no available headcount, or lacks the visitor traffic required to run A/B tests.
Cost is a consideration. A fully-loaded growth team consisting of a handful of engineers, a PM, and a designer costs approximately 1 million dollars annually. To justify this, a rule of thumb is to have at least $5 million dollars in recurring revenue – a milestone often achieved at around the Series B stage.
Despite the presence of growth engineering at many public consumer tech companies, the field itself is still quite new, as a discipline and as a proper title.
Brief history of growth engineering
When I joined Opendoor in 2016, there was a head of growth but no dedicated growth engineers, but there were by the time I left in 2020. At MasterClass soon after, there was a growth org and a dozen dedicated growth engineers. So when did growth engineering originate?
The story is that its origins lie at Facebook in 2007. The team was created by then-VP of platform and monetization Chamath Palihapitiya. Reforce founder and CEO Brian Balfour shares:
“Growth (the kind found on an org chart) began at Facebook under the direction of Chamath Palihapitiya. In 2007, he joined the early team in a nebulous role that fell somewhere between Product, Marketing, and Operations. According to his retelling of the story on Recode Decode, after struggling to accomplish anything meaningful in his first year on the job, he was on the verge of being fired.Sheryl Sandberg joined soon after him, and in a hail mary move he pitched her the game-changing idea that led to the creation of the first-ever growth team. This idea not only saved his job, but earned him the lion’s share of the credit for Facebook’s unprecedented growth.At the time, Sheryl and Mark asked him, “What do you call this thing where you help change the product, do some SEO and SEM, and algorithmically do this or that?”His response: “I don’t know, I just call that, like, Growth, you know, we’re going to try to grow. I’ll be the head of growing stuff."And just like that, Growth became a thing.”
Rather than focus on a particular product or feature, the growth team at Facebook focused on moving the needle, and figuring out which features to work on. These days, Meta employs hundreds if not thousands of growth engineers.
2. What do Growth Engineers work on?
Before we jump into concrete examples, let’s identify three primary focus areas that a growth engineer’s work usually involves.
- Business-facing work – improving the business directly
- Empowerment work – enabling other teams to improve the business
- Platform work – improving the velocity of the above activities
Let’s go through all three:
Business-facing work
This is the bread and butter of growth engineering, and follows a common pattern:
- Implement an idea. Try something big or small to try and move a key business metric, which differs by team but is typically related to conversion rate or retention.
- Quantify impact. Usually via A/B testing.
- Analyze impact. Await results, analyze impact, ship or roll back – then go back to the first step.
Experiments can lead to sweeping or barely noticeable changes. A famous “I can’t believe they needed to test this” was when Google figured out which shade of blue generates the most clicks. At MasterClass, we tested things across the spectrum:
- Small: should we show the price right on the homepage, was that a winner? Yes, but we framed it in monthly terms of $15/month, not $180/year.
- Medium: when browsing a course page, should we include related courses, or more details about the course itself? Was it a winner? After lengthy experimentation, it was hard to tell: both are valuable and we needed to strike the right balance.
- Large: when a potential customer is interested, do we take them straight to checkout, or encourage them to learn more? Counterintuitively, adding steps boosted conversion!
Empowerment
One of the best ways an engineer can move a target metric is by removing themselves as a bottleneck, so colleagues from marketing can iterate and optimize freely. To this end, growth engineers can either build internal tools or integrate self-serve MarTech (Marketing Technology) vendors.
With the right tool, there’s a lot that marketers can do without engineering’s involvement:
- Build and iterate on landing pages (Unbounce, Instapage, etc)
- Draft and send email, SMS and Push Notifications (Iterable, Braze, Customer.io, etc)
- Connect new advertising partners (Google Tag Manager, Segment, etc)
We go more into detail about benefits and applications in the MarTech section of Tech Stack, below.
Platform work
As a business scales, dedicated platform teams help improve stability and velocity for the teams they support. Within growth, this often includes initiatives like:
- Experiment Platform. Many parts of running an experiment can be standardized, from filtering the audience, to bucketing users properly, to observing statistical methodology. Historically, companies built reusable Experiment Platforms in-house, but more recently, vendors such as Eppo and Statsig have grown in popularity with fancy statistical methodologies like “Controlled Using Pre-Experiment Data” (CUPED) that give more signal with less data.
- Reusable components. Companies with standard front-end components for things like headlines, buttons, and images, dramatically reduce the time required to spin up a new page. No more "did you want 5 or 6 pixels here" with a designer; instead growth engineers rely on tools like Storybook to standardize and share reusable React components.
- Monitoring. Growth engineering benefits greatly from leveraging monitoring to compensate for reduced code coverage. High-quality business metric monitoring tools can detect bugs before they cause damage.
When I worked at MasterClass, having monitoring at the ad layer prevented at least one six-figure incident. One Friday, a marketer accidentally broadened the audience for a particular ad from US-only, to worldwide. In response, the Facebook Ad algorithm went on a spending spree, bringing in plenty of visitors from places like Brazil and India, whom we knew from past experience were unlikely to purchase the product. Fortunately, our monitoring noticed the low-performing campaign within minutes, and an alert was sent to the growth engineer on-call, who immediately reached out to the marketer and confirmed the change was unintentional, and then shut down the campaign.
Without this monitoring, a subtle targeting error like this could have gone unnoticed all weekend and would have eaten up $100,000+ of marketing budget. This episode shows that platform investment can benefit everyone; and since growth needs them most, it’s often the growth platform engineering team which implements them.
As the day-to-day work of a Growth Engineer shows, A/B tests are a critical tool to both measure success and learn. It’s a numbers game: the more A/B tests a team can run in a given quarter, the more of them will end up winners, making the team successful. It’s no wonder, then, that Growth Engineering will pull out all the stops to improve velocity.
3. Why Growth Engineers move faster than Product Engineers
On the surface, growth engineering teams look like product engineering ones; writing code, shipping pull requests, monitoring on-call, etc. So how do they move so much faster? The big reason lies in philosophy and focus, not technology. To quote Elena Verna, head of growth at Dropbox:
“Product Engineering teams ship to build; Growth Engineering teams ship to learn.”
Real-world case: price changes at Masterclass
A few years ago at MasterClass, the growth team wanted to see if changing our pricing model to multiple tiers would improve revenue.
Inspired in part by multiple pricing tiers for competitors such as Netflix (above), Disney Plus, and Hulu.
The “multiple pricing tier” proposal for MasterClass.
From a software engineering perspective, this was a highly complex project because:
- Backend engineering work: the backend did not yet support multiple pricing options, requiring a decent amount of engineering, and rigorous testing to make sure existing customers weren’t affected.
- Client app changes: on the device side, multiple platforms (iOS, iPad, Android, Roku, Apple TV, etc) would each need to be updated, including each relevant app store.
The software engineering team estimated that becoming a “multi-pricing-tier” company would take months across numerous engineering teams, and engineering leadership was unwilling to greenlight that significant investment.
We in growth engineering took this as a challenge. As usual, our goal was not just to add the new pricing model, but to learn how much money it might bring in. The approach we ended up proposing was a Fake Door test, which involves offering a not-yet-available option to customers to gauge interest level. This was risky, as taking a customer who’s ready to pay and telling them to join some kind of waiting list is a colossal waste, and risks making them feel like the target of a “bait and switch” trick.
We found a way. The key insight was that people are only offended about a “bait and switch”, if the “switch” is worse than the “bait.” Telling customers they would pay $100 and then switching to $150 would cause a riot, but starting at $150 and then saying “just kidding, it’s only $100” is a pleasant surprise.
The good kind of surprise.
So long as every test “pricing tier” is less appealing – higher prices, fewer features – than the current offering, we could “upgrade” customers after their initial selection. A customer choosing the cheapest tier gets extra features at no extra cost, while a customer choosing a more expensive tier is offered a discount.
We created three new tiers, at different prices. The new “premium” tier would describe the existing, original offering. Regardless of what potential customers selected, they got this “original offering,” during the experiment.
The best thing about this was that no backend changes were required. There were no real, new, back-end pricing plans; everybody ended up purchasing the same version of MasterClass for the same price, with the same features. The entirety of the engineering work was on building a new pricing page, and the “congratulations, you’ve been upgraded” popup. This took just a few days.
Within a couple of weeks, we had enough data to be confident the financial upside of moving to a multi-pricing-tier model would be significant. With this, we’re able to convince the rest of engineering’s leadership to invest in building the feature properly. In the end, launching multiple pricing tiers turned out to be one of the biggest revenue wins of the year.
Building a skyscraper vs building a tent
The MasterClass example demonstrates the spirit of growth engineering; focusing on building to learn, instead of building to last. Consider building skyscrapers versus tents.
Building a tent optimizes for speed of set-up and tear-down over longevity. You don’t think of a tent as one that is shoddy or low-quality compared to skyscrapers: it’s not even the same category of buildings! Growth engineers maximize use of lightweight materials. To stick with the tents vs skyscraper metaphor: we prioritize lightweight fabric materials over steel and concrete whenever possible. We only resort to traditional building materials when there’s no other choice, or when a direction is confirmed as correct. Quality is important – after all, a tent must keep out rain and mosquitoes. However, the speed-vs-durability tradeoff decision results in very different approaches and outcomes.
4. Tech stack
At first glance, growth and product engineers use the same tooling, and contribute to the same codebases. But growth engineering tends to be high-velocity, experiment-heavy, and with limited test coverage. This means that certain “nice to have” tools for product engineering are mission-critical for growth engineers.

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

2024-12-08 05:33:02Chef's notes
This is my late partner's award winning Cajun rice & beans recipe. It's an updated take on the traditional Cajun comfort food.
Chef Darin was a classically trained chef who spent 30+ years in the kitchen perfecting his recipes, and delivering authentic Cajun and Creole food to his patrons. This is a 5-star dish that will earn the respect of the most discerning Cajun afficionado. You won't be disappointed.
I suggest making this recipe exactly as directed the first time, and then make whatever adjustments you want for future batches. Also, don't cheap out on the Andouille. No Johnsonville or Hillshire Farms. Chef Aidelle's is a good choice, as is Silva's from Whole Foods. They cost a few extra bucks, but it's absolutely worth it.

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

2025-05-21 07:49:22หลายคนอาจแปลกใจว่า ทำไมน้ำมันจากผลไม้แบบอโวคาโดถึงกล้าขึ้นชั้น “ไขมันดี” ไปเทียบกับน้ำมันมะกอกได้ ทั้งที่ฟังดูไม่หรูเท่า แต่ความจริงแล้ว น้ำมันอโวคาโดคือหนึ่งในไม่กี่ชนิดของน้ำมันพืชที่สกัดจาก “เนื้อผล” ไม่ใช่เมล็ด ทำให้มีโครงสร้างไขมันที่ต่างจาก seed oils ทั่วไป ทั้งในแง่กรดไขมัน สารต้านอนุมูลอิสระ และวิธีที่มันตอบสนองต่อความร้อน
น้ำมันอโวคาโดมีกรดไขมันไม่อิ่มตัวตำแหน่งเดียว (MUFA) เป็นหลัก โดยเฉพาะ กรดโอเลอิก (Oleic acid) ซึ่งคิดเป็นประมาณ 65–70% ของไขมันทั้งหมด ใกล้เคียงน้ำมันมะกอกเลย แต่เหนือกว่าเล็กน้อยในแง่ของ ค่าควัน (smoke point) ที่สูงถึง 250°C (แบบ refined) และราว 190–200°C (แบบ cold-pressed) ทำให้เหมาะกับการผัดหรือทอดแบบเบา ๆ โดยไม่ทำให้เกิดสารพิษจากไขมันไหม้เร็วเท่าน้ำมันที่ค่าควันต่ำ
นอกจาก MUFA แล้ว น้ำมันอโวคาโดยังมี PUFA อยู่เล็กน้อย ประมาณ 10–14% ส่วนใหญ่คือ โอเมก้า-6 (linoleic acid) ซึ่งก็มีปริมาณไม่มากจนถึงขั้นต้องห่วงเรื่องการอักเสบ เหมือนที่เจอกับพวกน้ำมันรำข้าวหรือถั่วเหลืองที่ PUFA พุ่งสูงเกิน 50% ขึ้นไป และที่สำคัญ...โอเมก้า-3 ในอโวคาโดก็มีอยู่บ้างในรูปของ ALA แม้ไม่เยอะ แต่ก็บอกได้ว่าโครงสร้างโดยรวมของมันสมดุลพอควร ถ้ามองในรูปแบบพลังงานไขมัน ก็ถือว่าใช้ได้เลย
อโวคาโดออยล์แบบไม่ผ่านกระบวนการ (unrefined) ยังมีพวก วิตามินอี (tocopherols) ในระดับประมาณ 13–20 มก. ต่อ 100 กรัม และสารโพลีฟีนอลบางชนิดราวๆ 30–50 mg GAE/100 กรัม เช่น catechins และ procyanidins อยู่บ้าง ซึ่งช่วยลดการเกิดอนุมูลอิสระตอนเจอความร้อน และยังดีต่อผิวหนังในมิติของ skincare ด้วยนะ
ถ้าใช้แบบ cold-pressed, unrefined กลิ่นมันจะออกคล้ายอะโวคาโดสุก ๆ หน่อย มีความเขียวอ่อน ๆ และครีมมี่เล็ก ๆ ซึ่งเหมาะกับการคลุกหรือปรุงแบบ low heat มากกว่าการทอดแรง ส่วนถ้าจะใช้ทำอาหารจริงจัง น้ำมันอโวคาโดแบบ refined ก็จะกลิ่นอ่อนลง สีใสขึ้น และทนไฟได้ดีขึ้นมาก เหมาะจะเอาไปทำ steak หรือผัดไฟกลางได้แบบไม่กังวล อันนี้ก็แล้วแต่จะเลือกนะครับ
ถ้าจะพูดให้ตรง… น้ำมันอโวคาโดคือ “ไขมันผลไม้สายกลาง” ที่ทั้งทนไฟพอใช้ ทำครัวได้หลากหลาย และไม่บิดเบือนสัดส่วนไขมันในร่างกายเราจนเกินไป และถ้าเลือกแบบที่ผลิตดี ไม่โดนสารเคมี ไม่โดนไฮโดรเจนเสริม ก็ถือว่าเป็นน้ำมันดีอีกตัวที่วางใจได้ในครัวจริง ๆ
ใครอยากลองทำเองที่บ้านก็ได้นะ แบบง่ายๆแค่มีผ้าขาวบาง https://youtu.be/gwHGgoMuRnI?si=ehcQceabdbMGfkwG
นอกจากนี้บางคนอาจเคยเห็นโฆษณาสินค้าที่มีน้ำมันจากเมล็ดและเปลือกด้วยใช่ไหมครับ
เมล็ดอโวคาโดนั้นอุดมไปด้วย ไขมันน้อยกว่ามาก เมื่อเทียบกับเนื้อผล แต่มีสารพฤกษเคมีบางชนิดที่นักวิจัยสนใจ เช่น ฟีนอลิกส์ (phenolics), ฟลาโวนอยด์, สารต้านจุลชีพ และ ไฟเบอร์ละลายน้ำสูง การสกัดน้ำมันจากเมล็ดมักจะใช้ ตัวทำละลาย (solvent extraction) หรือ วิธี supercritical CO₂ ไม่ค่อยทำแบบ cold-pressed เพราะน้ำมันน้อยเกิน ปริมาณน้ำมันจากเมล็ดนั้นต่ำมาก คือไม่ถึง 5% ของน้ำหนักแห้ง ทำให้ไม่ค่อยนิยมในเชิงพาณิชย์ น้ำมันจากเมล็ดมักไม่ได้เอาไว้ปรุงอาหาร แต่เอาไปใช้ ด้านเวชสำอาง หรือ functional food มากกว่า เช่น ครีมทาผิว แชมพู หรือผลิตภัณฑ์ชะลอวัย
เปลือกอโวคาโดมี สารต้านจุลชีพและสารต้านออกซิเดชัน บางชนิดเช่นกัน แต่มีไขมันน้อยมากแทบจะไม่มีเลย บางงานวิจัยพยายามสกัดพวก polyphenols หรือสารสีธรรมชาติจากเปลือก เพื่อใช้ในอาหารเสริม หรือผลิตภัณฑ์สุขภาพ ไม่ได้สกัดน้ำมันโดยตรง แบบเนื้อผล แต่ใช้เปลือกเป็นวัตถุดิบเสริมมากกว่า เช่น ผสมในน้ำมันหลักเพื่อเพิ่มคุณสมบัติด้านสุขภาพ
ส่วนตัวคิดว่าไม่ต้องทำเองหรอกครับ ซื้อกินเหอะ 555 เจ้านี้ดีนะ อยู่คู่วงการสุขภาพมาแต่แรกๆเลย https://s.shopee.co.th/8zsnEsLrvh

2025-03-26 20:54:33Capitalism is the most effective system for scaling innovation. The pursuit of profit is an incredibly powerful human incentive. Most major improvements to human society and quality of life have resulted from this base incentive. Market competition often results in the best outcomes for all.
That said, some projects can never be monetized. They are open in nature and a business model would centralize control. Open protocols like bitcoin and nostr are not owned by anyone and if they were it would destroy the key value propositions they provide. No single entity can or should control their use. Anyone can build on them without permission.
As a result, open protocols must depend on donation based grant funding from the people and organizations that rely on them. This model works but it is slow and uncertain, a grind where sustainability is never fully reached but rather constantly sought. As someone who has been incredibly active in the open source grant funding space, I do not think people truly appreciate how difficult it is to raise charitable money and deploy it efficiently.
Projects that can be monetized should be. Profitability is a super power. When a business can generate revenue, it taps into a self sustaining cycle. Profit fuels growth and development while providing projects independence and agency. This flywheel effect is why companies like Google, Amazon, and Apple have scaled to global dominance. The profit incentive aligns human effort with efficiency. Businesses must innovate, cut waste, and deliver value to survive.
Contrast this with non monetized projects. Without profit, they lean on external support, which can dry up or shift with donor priorities. A profit driven model, on the other hand, is inherently leaner and more adaptable. It is not charity but survival. When survival is tied to delivering what people want, scale follows naturally.
The real magic happens when profitable, sustainable businesses are built on top of open protocols and software. Consider the many startups building on open source software stacks, such as Start9, Mempool, and Primal, offering premium services on top of the open source software they build out and maintain. Think of companies like Block or Strike, which leverage bitcoin’s open protocol to offer their services on top. These businesses amplify the open software and protocols they build on, driving adoption and improvement at a pace donations alone could never match.
When you combine open software and protocols with profit driven business the result are lean, sustainable companies that grow faster and serve more people than either could alone. Bitcoin’s network, for instance, benefits from businesses that profit off its existence, while nostr will expand as developers monetize apps built on the protocol.
Capitalism scales best because competition results in efficiency. Donation funded protocols and software lay the groundwork, while market driven businesses build on top. The profit incentive acts as a filter, ensuring resources flow to what works, while open systems keep the playing field accessible, empowering users and builders. Together, they create a flywheel of innovation, growth, and global benefit.

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

2024-12-06 16:20:33As Bitcoin’s price continues to climb, the value of its smallest unit, the Satoshi, grows with it. Today, owning a million Satoshis is an affordable and wise investment—especially as Bitcoin reaches new heights. Here’s why a million Satoshis should be the minimum amount everyone owns and why cold storage is key to securing your future.
- Affordability and Future Value
While owning one full Bitcoin might seem out of reach for many, owning one million Satoshis is much more achievable. As Bitcoin continues to rise in value, a million Satoshis, which is currently worth around $250, could become worth $10,000 or more in the future. This makes owning a million Satoshis not just an entry into Bitcoin, but a solid step toward securing future wealth.
- A World Priced in Sats
Imagine a future where goods and services are priced in Satoshis. As Bitcoin gains widespread adoption, this scenario is becoming more likely. With Bitcoin potentially surpassing $1 million per coin, one million Satoshis will be worth a significant sum in the future. By owning this amount now, you’re setting yourself up for a future where everyday transactions are measured in Sats, ensuring your financial independence.
- A Hedge Against Inflation
With fiat currencies losing value over time, Bitcoin offers a deflationary alternative. Owning Satoshis is like holding a form of “sound money” that protects you from inflationary pressures. As Bitcoin’s value continues to grow, your Satoshis could outpace inflation, preserving your wealth for the long term.
- The Importance of Cold Storage
Storing your Satoshis securely is just as important as owning them. Cold storage solutions, like the Foundation Passport, Coldcard, or Bitkey, offer the highest level of security by keeping your private keys offline. This protects your Bitcoin from online threats, ensuring that your Satoshis remain safe for years to come.
Cold Storage Solutions
• Foundation Passport: Portable, secure, and open-source. A great option for long-term Bitcoin storage. • Coldcard: A highly secure hardware wallet that keeps your Bitcoin offline and out of reach from hackers. • Bitkey: A versatile, user-friendly cold storage solution integrated with your smartphone.
A Better Future with Bitcoin
Owning a million Satoshis today is not just about having a small piece of Bitcoin—it’s about securing a financial future where Bitcoin is the standard. Cold storage protects your wealth, and owning Bitcoin positions you to thrive in a decentralized, Bitcoin-driven economy. As Bitcoin continues to evolve, those who embrace it today will be ahead of the curve in a world where wealth is stored in Satoshis.

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

@ 04c915da:3dfbecc9
2025-03-10 23:31:30Bitcoin 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.
Usually stolen bitcoin for the reserve creates a perverse incentive. If governments see a 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.

2024-12-06 16:07:53In a world that often rewards conformity, being open-minded can be a radical act. It is a choice to embrace curiosity, challenge assumptions, and allow life to surprise you. When we open our minds, we invite new possibilities—not just in the realm of ideas but in every aspect of existence, from consciousness expansion to financial freedom with Bitcoin, and even finding a life partner. Let’s explore how this mindset can transform your reality.
- Open-Mindedness and Consciousness
The first step to expanding consciousness is realizing how much there is to learn. By questioning the default narratives we’ve inherited—about who we are, why we’re here, and what reality itself means—we create space for deeper awareness.
This could involve practices like meditation, exploring alternative philosophies, or studying ancient wisdom traditions like Traditional Chinese Medicine (TCM). These practices teach us that the mind is not a fixed entity but a fluid and evolving tool. When we let go of rigid beliefs, we begin to notice synchronicities, experience heightened awareness, and even tap into higher states of being.
Being open-minded in this sense doesn’t mean blindly accepting everything; it means cultivating discernment while remaining curious. It’s in this openness that we discover the profound interconnectedness of all things.
- Bitcoin: Financial Freedom through Innovation
For many, Bitcoin is a misunderstood or intimidating concept. But being open-minded to alternative systems can lead to incredible breakthroughs—not just financially but philosophically. Bitcoin isn’t just “digital money”; it represents decentralization, transparency, and freedom from traditional financial systems that have long prioritized the few over the many.
Adopting Bitcoin often requires a mental shift. It’s not about chasing short-term gains but about understanding the principles of sound money, scarcity, and peer-to-peer networks. For those willing to question how money works and why it matters, Bitcoin offers an opportunity to participate in a financial revolution that empowers individuals.
Openness to Bitcoin can also reshape your mindset toward technology, personal sovereignty, and global collaboration. It’s not just a currency; it’s a philosophy of trust and innovation.
- Finding Love Through Open-Mindedness
The search for a life partner often mirrors our internal beliefs about ourselves and others. An open mind can transform how we approach relationships, making space for unexpected connections.
When we let go of rigid expectations—about what our partner “should” look like, where we’ll meet them, or how a relationship should progress—we allow love to unfold organically. Sometimes, the most wonderful spouse enters our lives when we least expect it, perhaps through a chance encounter or shared passion.
Open-mindedness in love also means being willing to grow together, embracing differences, and learning from one another. It’s about building a relationship rooted in mutual respect, curiosity, and the belief that you can continually discover new facets of your partner (and yourself) over time.
Final Thoughts: The Ripple Effect of Open-Mindedness
Whether it’s exploring consciousness, adopting Bitcoin, or finding a wonderful spouse, being open-minded is a skill that creates ripple effects across all areas of life. It’s not just about embracing new ideas—it’s about living with the belief that the universe has infinite possibilities waiting for you to discover.
By opening your mind, you open doors: to deeper awareness, financial independence, and love that feels like home. The more you explore, the more you realize that being open-minded doesn’t just expand your world—it transforms it.
So, the next time you’re faced with something unfamiliar or challenging, ask yourself: What could I learn if I let myself be curious?
On this journey, everything becomes possible.

2024-12-06 15:47:43The financial markets are at a crossroads. With SPY trading at $608 and QQQ at $525, these flagship ETFs are steadily moving toward the $1,000 per share milestone. While the milestone itself is symbolic, its implications for investors and the broader market could be transformative.
For many retail investors, high share prices—despite the availability of fractional shares—create a psychological barrier. Investors instinctively perceive higher prices as less accessible, even if the value proposition remains unchanged. This perception challenges the traditional market and raises the question:
How will markets adapt as SPY and QQQ continue their climb toward $1,000 per share?
Let’s explore two potential paths forward, including how Bitcoin ETFs and direct Bitcoin ownership could reshape how we invest and define “The Market.”
- New Standardized Products for Retail Investors
When SPY and QQQ reach higher price levels, markets will likely introduce new products to maintain accessibility. This adaptation wouldn’t be unprecedented. For example, Fidelity’s FNILX, a zero-expense index fund that tracks the S&P 500, provides a low-cost and highly accessible alternative to traditional funds.
However, FNILX is a mutual fund and doesn’t offer the liquidity or tradability of ETFs, which makes ETFs far more appealing to active traders and long-term investors alike. The ETF equivalent of FNILX would likely take the form of new products specifically designed to solve the “high price barrier” problem.
What These New ETFs Could Look Like:
• Lower Price Points: New ETFs might adopt alternative share structures or tokenization to fractionalize ownership while maintaining correlation to major indices like SPY and QQQ. • Cost-Effective Options: Providers could offer these products with reduced or zero fees, similar to FNILX, but with the tradability of ETFs. • Trader-Friendly Designs: These ETFs would retain liquidity and flexibility, ensuring active investors can continue trading them easily.
Such products would act as next-generation ETFs, satisfying demand for accessibility while keeping retail investors engaged in traditional markets.
- The Rise of Bitcoin as an Alternative Market Standard
While SPY and QQQ dominate the current investment landscape, the rise of Bitcoin ETFs and direct Bitcoin ownership presents a compelling alternative. Bitcoin’s decentralized nature and finite supply make it fundamentally different from traditional equities, and its adoption as a financial instrument is growing rapidly.
Bitcoin ETFs: A Familiar Entry Point
Bitcoin ETFs, like IBIT, bridge the gap between the traditional financial system and the world of cryptocurrency. They allow investors to gain Bitcoin exposure through familiar platforms, such as brokerage accounts, without needing to manage private keys or wallets.
Advantages of Bitcoin ETFs: 1. Ease of Use: Easily accessible through existing brokerage platforms, making Bitcoin exposure as simple as buying a stock.
2. Regulated Framework: Operates within traditional financial regulations, providing a sense of security for traditional investors. 3. Portfolio Integration: Fits seamlessly into diversified portfolios, allowing Bitcoin exposure alongside traditional assets.
However, Bitcoin ETFs have limitations, including management fees, lack of true ownership, and reliance on third-party custodians.
Self-Custody Bitcoin: True Financial Sovereignty
For investors who want to fully embrace the decentralized ethos of Bitcoin, self-custody offers unparalleled financial sovereignty. By purchasing Bitcoin directly and storing it in a private wallet, investors take full control of their assets.
Benefits of Self-Custody: 1. True Ownership: You hold the private keys, ensuring no third party has control over your Bitcoin.
2. Censorship Resistance: Self-custodied Bitcoin is immune to freezes, seizures, or restrictions. 3. Decentralization: You actively contribute to the resilience of the Bitcoin network. 4. Security: Proper practices, like using hardware wallets or multi-signature solutions, provide robust protection against theft or institutional failure.
Self-custody does require responsibility, but the learning curve is shrinking as user-friendly tools and educational resources become more widely available.
A Broader Shift in Market Perception
As SPY and QQQ climb toward $1,000, Bitcoin may begin to redefine how we measure market health and economic performance. Traditionally, indices like the S&P 500 have been seen as benchmarks for the economy. In the future, Bitcoin’s price and adoption metrics could serve as a parallel or even competing measure.
Why Bitcoin Could Become a New Market Standard:
• Global Inclusion: Bitcoin is accessible to anyone with an internet connection, breaking down geographic and economic barriers. • Inflation Hedge: Its finite supply makes it a powerful store of value, particularly in inflationary environments. • Decentralized Economy: Bitcoin represents a global, decentralized economic standard, uncorrelated with traditional equity markets.
Implications for the Future of Investing
For Traditional ETFs:
As SPY and QQQ approach $1,000, the introduction of new, lower-priced ETF products will be critical to maintaining retail engagement. These innovations could fragment demand across products, altering trading volumes and creating new dynamics for liquidity and volatility.
For Bitcoin:
The rise of Bitcoin ETFs and self-custody will empower investors to rethink how they store and grow their wealth. The decision between convenience (Bitcoin ETFs) and sovereignty (self-custody) will define a new era of financial choice.
Takeaway: Preparing for a Transformative Future
The approaching $1,000 milestone for SPY and QQQ is more than just a numerical milestone—it signals a shift in how markets must adapt to the needs of investors. Whether through new standardized ETFs or the growing adoption of Bitcoin ETFs and self-custody, the investment landscape is evolving.
For investors, this is an opportunity to embrace change. Will you continue to follow traditional benchmarks, explore new Bitcoin products, or take control through self-custody?
One thing is clear: the markets of tomorrow will reward those who adapt, innovate, and educate themselves. The future isn’t about choosing between systems—it’s about using the tools that empower you to thrive.

2025-05-21 05:45:00CHAPTER TWENTY FOUR
Back at JP Towers, James had already anticipated the move. He had cameras and witness accounts from the anniversary event, stored securely in multiple locations. He knew the public had a short memory but a long hunger for drama. One misstep could tilt public sentiment.
But James was no longer playing to survive.
He was playing to reign.
Later that night, he stood before a mirror, adjusting the cuffs of his suit. In his reflection, he saw more than his own face; he saw the faces of those who had mocked, betrayed, and underestimated him. And he saw the legacy he was building not just for himself, but for those who once believed justice was a myth.
He whispered to the reflection, “Let them come. Let them burn what’s left of their dignity. I’ll rise through the smoke again. Because I always do.”
Outside, the wind howled like a prophecy through the high-rises.
The days that followed carried a subtle tension that coiled around the city's heartbeat. JP Enterprises thrived outwardly, stock prices climbed, investor confidence surged, and the company continued to solidify its dominion over the corporate landscape. But beneath the facade of calm and progress, a tempest brewed in silence.
James, the man once ridiculed and ostracized, now sat at the summit of power, yet his enemies, battered but unbroken, plotted from the shadows.
In an undisclosed meeting room within the Executive Wing, James convened with his most trusted circle Charles, Rita, and Sandra. The room was dimly lit, the atmosphere sober, with every eye locked onto the digital presentation being displayed.
On the screen were surveillance stills, financial records, and intercepted messages.
Rita, ever composed, began, “We’ve confirmed that Helen and Mark are using a shell media outlet in a nearby province to rewrite the narrative surrounding the anniversary incident. They’re laundering stories through third-party publications to make it appear as if you orchestrated the bribery and the public drama.”
Sandra added, her voice laced with concern, “The young woman from the event she’s set to appear in a televised interview in two days. The preview clips suggest she’ll claim coercion, manipulation… that you paid her to falsely accuse Mark and Helen.”
Charles sat back in his chair, folding his arms. “It’s a desperate move,” he muttered, “but one that could sway public opinion if left unchecked.”
James didn’t flinch. His gaze was cold and calculated. “Let them speak,” he said. “Let her appear on screen, let the nation watch but when the time is right, we’ll release the real footage. Every confession, every whispered transaction, every threat they issued. And when we do, it won’t just be public opinion they lose, it'll be their freedom.”
The room fell silent. The weight of the plan was immense. James wasn’t simply fighting a smear campaign he was orchestrating the downfall of those who had haunted his past and jeopardized his future.
Across town, in a luxurious yet shadowy apartment, Helen paced furiously. Mark sat slouched on the couch, phone in hand, monitoring the latest headlines.
“She hasn’t confirmed the script yet,” Mark grumbled, referring to the woman they’d bribed. “She’s stalling. You think she’s flipping again?”
“She better not,” Helen spat. “We gave her a second chance, more money, more protection. If she dares cross us again...”
“Then we make her disappear,” Mark said coldly.
Helen paused. “Or we pin everything on her. Let her take the fall.”
Their desperation bled into their decisions. The empire they tried to build with lies and manipulation was already on unstable ground. They didn’t realize James wasn’t just steps ahead. Two days later, as the nation sat glued to their screens, the controversial interview aired. The woman, visibly tense, spoke her lines.
“Yes… he promised to protect me… he told me to say Mark and Helen bribed me… I was scared of what he might do if I didn’t cooperate…”
The hosts gasped, commentators argued, and the news cycle erupted.
For an hour, James’s name trended for all the wrong reasons.
And then the storm came.
JP Enterprises’ official communication channels released a statement followed by a seven-minute clip, unedited, raw, and crystal clear. It captured everything: the lady kneeling, pointing to Mark and Helen, the whispered confessions, the crowd’s reaction, Helen’s furious outburst. And, most damning of all, a covert recording of Helen threatening the woman in a private meeting.
The tide turned instantly.
Social media exploded not with outrage toward James, but with condemnation of the real culprits. Hashtags flipped. Influencers, journalists, and even rival corporations came to James’s defense. The woman fled the city within hours. Mark and Helen, now disgraced, faced not just the wrath of public judgment, but the immediate interest of law enforcement.
Back at the JP tower, James watched it all unfold. The screen reflected in his eyes as headlines changed: “President Vindicated,” “Corporate Sabotage Exposed,” “Justice Prevails in High-Stakes Feud.”
Charles walked in slowly, a faint smile on his lips. “It’s done.”
James nodded, his voice a calm murmur. “No. It’s only the beginning. I haven’t just protected my name, I've carved a legacy.”
He stood up, walking toward the window where the city stretched out beneath him, unaware of how close it had come to being ruled by lies.
Behind him, the quiet echo of Charles’s voice lingered: “Your enemies are falling, one by one.”

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

2025-04-04 06:58:30Introduction
If you have a functioning brain, it’s impossible to fully stand for any politician or align completely with any political party. The solutions we need are not found in the broken systems of power but in individual actions and local initiatives. Voting for someone may be your choice, but relying solely on elections every few years as a form of political activism is a losing strategy. People around the world have fallen into the trap of thinking that casting a ballot once every four years is enough, only to return to complacency as conditions worsen. Voting for the "lesser of two evils" has been the norm for decades, yet expecting different results from the same flawed system is naive at best.
The truth is, governments are too corrupt to save us. In times of crisis, they won’t come to your aid—instead, they will tighten their grip, imposing more surveillance, control, and wealth extraction to benefit the oligarch class. To break free from this cycle, we must first protect ourselves individually—financially, geographically, and digitally—alongside our families.
Then, we must organize and build resilient local communities. These are the only ways forward. History has shown us time and again that the masses are easily deceived by the political circus, falling for the illusion of a "savior" who will fix everything. But whether right, center, or left, the story remains the same: corruption, lies, and broken promises. If you possess a critical and investigative mind, you know better than to place your trust in politicians, parties, or self-proclaimed heroes. The real solution lies in free and sovereign individuals who reject the herd mentality and take responsibility for their own lives.
From the beginning of time, true progress has come from individuals who think for themselves and act independently. The nauseating web of politicians, billionaires, and oligarchs fighting for power and resources has never been—and will never be—the answer to our problems. In a world increasingly dominated by corrupted governments, NGOs, and elites, ordinary people must take proactive steps to protect themselves and their families.
1. Financial Protection: Reclaiming Sovereignty Through Bitcoin
Governments and central banks have long manipulated fiat currencies, eroding wealth through inflation and bailouts that transfer resources to the oligarch class. Bitcoin, as a decentralized, censorship-resistant, and finite currency, offers a way out. Here’s what individuals can do:
-
Adopt Bitcoin as a Savings Tool: Shift a portion of your savings into Bitcoin to protect against inflation and currency devaluation. Bitcoin’s fixed supply (21 million coins) ensures it cannot be debased like fiat money.
-
Learn Self-Custody: Store your Bitcoin in a hardware wallet or use open-source software wallets. Avoid centralized exchanges, which are vulnerable to government seizure or collapse.
-
Diversify Geographically: Hold assets in multiple jurisdictions to reduce the risk of confiscation or capital controls. Consider offshore accounts or trusts if feasible.
-
Barter and Local Economies: In times of crisis, local barter systems and community currencies can bypass failing national systems. Bitcoin can serve as a global medium of exchange in such scenarios.
2. Geographical Flexibility: Reducing Dependence on Oppressive Systems
Authoritarian regimes thrive on controlling populations within fixed borders. By increasing geographical flexibility, individuals can reduce their vulnerability:
-
Obtain Second Passports or Residencies: Invest in citizenship-by-investment programs or residency permits in countries with greater freedoms and lower surveillance.
-
Relocate to Freer Jurisdictions: Research and consider moving to regions with stronger property rights, lower taxes, and less government overreach.
-
Decentralize Your Life: Avoid keeping all your assets, family, or business operations in one location. Spread them across multiple regions to mitigate risks.
3. Digital Privacy: Fighting Surveillance with Advanced Tools
The rise of mass surveillance and data harvesting by governments and corporations threatens individual freedom. Here’s how to protect yourself:
-
Use Encryption: Encrypt all communications using tools like Signal or ProtonMail. Ensure your devices are secured with strong passwords and biometric locks.
-
Adopt Privacy-Focused Technologies: Use Tor for anonymous browsing, VPNs to mask your IP address, and open-source operating systems like Linux to avoid backdoors.
-
Reject Surveillance Tech: Avoid smart devices that spy on you (e.g., Alexa, Google Home). Opt for decentralized alternatives like Mastodon instead of Twitter, or PeerTube instead of YouTube.
-
Educate Yourself on Digital Privacy: Learn about tools and practices that enhance your online privacy and security.
4. Building Resilient Local Communities: The Foundation of a Free Future
While individual actions are crucial, collective resilience is equally important. Governments are too corrupt to save populations in times of crisis—history shows they will instead impose more control and transfer wealth to the elite.
To counter this, communities must organize locally:
-
Form Mutual Aid Networks: Create local groups that share resources, skills, and knowledge. These networks can provide food, medical supplies, and security during crises.
-
Promote Local Economies: Support local businesses, farmers, and artisans. Use local currencies or barter systems to reduce dependence on centralized financial systems.
-
Develop Off-Grid Infrastructure: Invest in renewable energy, water filtration, and food production to ensure self-sufficiency. Community gardens, solar panels, and rainwater harvesting are excellent starting points.
-
Educate and Empower: Host workshops on financial literacy, digital privacy, and sustainable living. Knowledge is the most powerful tool against authoritarianism.
5. The Bigger Picture: Rejecting the Illusion of Saviors
The deep corruption within governments, NGOs, and the billionaire class is evident. These entities will never act in the interest of ordinary people. Instead, they will exploit crises to expand surveillance, control, and wealth extraction. The idea of a political “savior” is a dangerous illusion. True freedom comes from individuals taking responsibility for their own lives and working together to build decentralized, resilient systems.
Conclusion: A Call to Action
The path to a genuinely free humanity begins with individual action. By adopting Bitcoin, securing digital privacy, increasing geographical flexibility, and building resilient local communities, ordinary people can protect themselves against authoritarianism. Governments will not save us—they are the problem. It is up to us to create a better future, free from the control of corrupt elites.
-
The tools for liberation already exist.

The question is: will we use them?

2025-03-07 00:26:37There is something quietly rebellious about stacking sats. In a world obsessed with instant gratification, choosing to patiently accumulate Bitcoin, one sat at a time, feels like a middle finger to the hype machine. But to do it right, you have got to stay humble. Stack too hard with your head in the clouds, and you will trip over your own ego before the next halving even hits.
Small Wins
Stacking sats is not glamorous. Discipline. Stacking every day, week, or month, no matter the price, and letting time do the heavy lifting. Humility lives in that consistency. You are not trying to outsmart the market or prove you are the next "crypto" prophet. Just a regular person, betting on a system you believe in, one humble stack at a time. Folks get rekt chasing the highs. They ape into some shitcoin pump, shout about it online, then go silent when they inevitably get rekt. The ones who last? They stack. Just keep showing up. Consistency. Humility in action. Know the game is long, and you are not bigger than it.
Ego is Volatile
Bitcoin’s swings can mess with your head. One day you are up 20%, feeling like a genius and the next down 30%, questioning everything. Ego will have you panic selling at the bottom or over leveraging the top. Staying humble means patience, a true bitcoin zen. Do not try to "beat” Bitcoin. Ride it. Stack what you can afford, live your life, and let compounding work its magic.
Simplicity
There is a beauty in how stacking sats forces you to rethink value. A sat is worth less than a penny today, but every time you grab a few thousand, you plant a seed. It is not about flaunting wealth but rather building it, quietly, without fanfare. That mindset spills over. Cut out the noise: the overpriced coffee, fancy watches, the status games that drain your wallet. Humility is good for your soul and your stack. I have a buddy who has been stacking since 2015. Never talks about it unless you ask. Lives in a decent place, drives an old truck, and just keeps stacking. He is not chasing clout, he is chasing freedom. That is the vibe: less ego, more sats, all grounded in life.
The Big Picture
Stack those sats. Do it quietly, do it consistently, and do not let the green days puff you up or the red days break you down. Humility is the secret sauce, it keeps you grounded while the world spins wild. In a decade, when you look back and smile, it will not be because you shouted the loudest. It will be because you stayed the course, one sat at a time. \ \ Stay Humble and Stack Sats. 🫡

2025-05-21 02:12:10ถ้าเอ่ยถึง CJ หลายคนอาจนึกถึงซอสเกาหลีรสจัดจ้าน หรือบะหมี่กึ่งสำเร็จรูปแบรนด์ดังที่ขายทั่วโลก แต่เบื้องหลังความสำเร็จของแบรนด์เหล่านั้น มีบริษัทแม่อย่าง CJ CheilJedang ที่ไม่ได้แค่ผลิตอาหารแปรรูป แต่เป็นหนึ่งในผู้เล่นใหญ่ของอุตสาหกรรมอาหารระดับโลก ด้วยฐานความรู้ลึกซึ้งในเทคโนโลยีชีวภาพ หนึ่งในแขนงที่โดดเด่นคือ CJ BIO ธุรกิจไบโอเทคโนโลยีที่เน้นการใช้ Microbial Fermentation หรือการหมักจุลินทรีย์เพื่อผลิตสารอาหารและวัตถุดิบอาหารคุณภาพสูงในระดับอุตสาหกรรม
ประวัติของ CJ BIO เริ่มจากจุดเล็ก ๆ แต่ทรงพลัง คือการผลิต โมโนโซเดียมกลูตาเมต (MSG) ซึ่งเป็นกรดอะมิโนชนิดหนึ่งที่มีบทบาทสำคัญในการเพิ่มรสชาติ “อูมามิ” ให้กับอาหารทั่วโลก จุดนี้เองที่ทำให้ CJ BIO ได้สะสมเทคโนโลยีหมักจุลินทรีย์ในระดับอุตสาหกรรมมายาวนานกว่า 60 ปี ด้วยโรงงานหมักขนาดใหญ่ที่ตั้งอยู่ในหลายประเทศ เช่น เกาหลีใต้ จีน บราซิล อินโดนีเซีย และสหรัฐอเมริกา ทำให้ CJ BIO กลายเป็นหนึ่งในผู้ผลิตกรดอะมิโนและวัตถุดิบอาหารหมักจุลินทรีย์รายใหญ่ของโลก
แต่ถ้าให้พูดแบบง่าย ๆ การหมักจุลินทรีย์ของ CJ BIO นั้น ไม่ใช่แค่ “การทำอาหาร” ธรรมดา ๆ แต่เป็นการ “สร้างอาหารในระดับโมเลกุล” ตั้งแต่พื้นฐาน ซึ่งถือเป็นเทคโนโลยีที่สำคัญสำหรับอนาคตของอาหาร เพราะมันช่วยให้เราสามารถผลิตโปรตีน กรดอะมิโน และสารอาหารต่าง ๆ ที่มีคุณภาพสูงและควบคุมได้ในโรงงานขนาดใหญ่ โดยไม่ต้องพึ่งพาการเกษตรแบบดั้งเดิมที่ต้องใช้พื้นที่มากและมีผลกระทบต่อสิ่งแวดล้อม
เมื่อเทรนด์โลกกำลังเปลี่ยนไปในทางที่ผู้บริโภคหันมาใส่ใจสุขภาพและสิ่งแวดล้อมมากขึ้น เรื่อง “อาหารจากห้องแล็บ” หรือ “อาหารเทคโนโลยีชีวภาพ” จึงกลายเป็นสิ่งที่ได้รับความสนใจอย่างมาก และนี่เองที่ทำให้ CJ BIO ไม่ได้หยุดอยู่แค่ Microbial Fermentation แบบดั้งเดิม แต่เริ่มขยับเข้าสู่โลกใหม่ของ Precision Fermentation การใช้จุลินทรีย์ที่ผ่านการดัดแปลงพันธุกรรมอย่างแม่นยำ เพื่อผลิตโปรตีนหรือสารอาหารเฉพาะอย่างที่ต้องการ
ความเคลื่อนไหวที่สำคัญเกิดขึ้นในปี 2022 เมื่อ CJ CheilJedang ประกาศลงทุนใน New Culture สตาร์ทอัพสัญชาติอเมริกันที่กำลังพัฒนา “ชีสไร้วัว” ด้วยเทคโนโลยี Precision Fermentation ซึ่ง New Culture ใช้จุลินทรีย์ที่ถูกออกแบบมาเพื่อผลิตโปรตีนเคซีน โปรตีนหลักในน้ำนมวัว โดยไม่ต้องมีวัวจริงเลย นั่นหมายความว่าชีสที่ผลิตออกมาจะไม่มีส่วนผสมจากสัตว์จริง ๆ แต่ยังคงรสชาติและเนื้อสัมผัสเหมือนชีสธรรมชาติทุกประการ
การลงทุนครั้งนี้ของ CJ CheilJedang บริษัทแม่ของ CJ BIO จึงถือเป็นการผนึกกำลังระหว่างเทคโนโลยีดั้งเดิมที่ผ่านการพิสูจน์แล้วในระดับอุตสาหกรรม กับนวัตกรรมที่พร้อมเปลี่ยนแปลงวงการอาหารครั้งใหญ่
ถ้าให้เปรียบเทียบง่าย ๆ CJ BIO เหมือนกับ “โรงงานปั้นโมเลกุลอาหาร” ที่มีความเชี่ยวชาญสูงในการจัดการกับจุลินทรีย์และการผลิตกรดอะมิโนหลากหลายชนิด โดยเฉพาะ MSG ซึ่งถือเป็น “พี่ใหญ่” ในกลุ่มกรดอะมิโนที่ช่วยเพิ่มรสชาติและถูกใช้ในอุตสาหกรรมอาหารทั่วโลก
ความเชี่ยวชาญในการผลิต MSG นี้เอง คือฐานกำลังสำคัญที่ทำให้ CJ BIO สามารถขยายขอบเขตไปสู่การผลิตโปรตีนด้วย Precision Fermentation ได้อย่างมั่นใจ เพราะกระบวนการหมักจุลินทรีย์เพื่อผลิตกรดอะมิโนและโปรตีนนั้นมีความคล้ายคลึงกันในเชิงเทคนิคและการควบคุมคุณภาพ
CJ BIO มีโรงงานหมักจุลินทรีย์ที่ทันสมัยและขนาดใหญ่กระจายอยู่ทั่วโลก สามารถผลิตวัตถุดิบในปริมาณมหาศาลเพื่อตอบสนองตลาดอาหารที่เติบโตอย่างรวดเร็ว และการมีเครือข่ายโรงงานแบบนี้ทำให้ CJ BIO มีความได้เปรียบในการลดต้นทุนและควบคุมคุณภาพอย่างเข้มงวด
อนาคตที่ CJ BIO กำลังเดินไปนั้น ไม่ใช่แค่การผลิตวัตถุดิบอาหารธรรมดา ๆ แต่คือการสร้างนวัตกรรมที่จะเปลี่ยนแปลงวิธีการผลิตและการบริโภคอาหารของโลก
เมื่อผลิตภัณฑ์จากเทคโนโลยี Precision Fermentation อย่างชีสไร้วัว ไข่ไร่ไก่ หรือโปรตีนทางเลือกต่าง ๆ เริ่มเข้ามาในตลาดมากขึ้น เราอาจจะได้เห็น CJ BIO ทำหน้าที่เหมือน “Intel Inside” ของวงการอาหารอนาคต ที่อยู่เบื้องหลังผลิตภัณฑ์สำคัญ ๆ ที่ผู้บริโภคชื่นชอบโดยไม่รู้ตัว
นี่คือเหตุผลที่ทำให้การมองแค่แบรนด์อาหารหรือการตลาดที่พูดถึง “ความยั่งยืน” หรือ “อาหารปลอดสัตว์” ยังไม่พอ เราต้องมองให้ลึกไปถึงระบบนิเวศของเทคโนโลยีและทุนที่อยู่เบื้องหลัง เพราะนั่นคือเกมกระดานใหญ่ที่กำลังขยับเปลี่ยนแปลงวงการอาหารโลกอย่างแท้จริง

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

2025-03-04 17:00:18This 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.

2024-12-05 17:26:41If you could earn between 100-1,000 sats a day, what would that amount to if Bitcoin reached $1,000,000 per coin? Let’s do the math:
1 Bitcoin (BTC) = 100,000,000 satoshis (sats).
Current Bitcoin price = $101,000.
Future Bitcoin price = $1,000,000.
Daily Earnings in Fiat Equivalent at $1M/BTC:
• 100 sats/day = 0.000001 BTC/day = $1.00/day • 1,000 sats/day = 0.00001 BTC/day = $10.00/day
Annual Earnings at $1M/BTC:
• 100 sats/day x 365 days = $365/year • 1,000 sats/day x 365 days = $3,650/year
Even at the smallest level—earning 100 sats a day—you’re positioning yourself for significant long-term wealth as Bitcoin’s value increases. It’s a perfect example of the power of accumulation over time.
Why Every Sat Matters
Bitcoin is scarce, with only 21 million BTC to ever exist. That’s 2,100 trillion sats for the entire world. Each satoshi is a fraction of a finite resource, making it inherently valuable. If someone gives you even 1 satoshi, they are saying, “I appreciate your work. You’re making a difference.”
Whether you’re earning sats through:
• Working: Salary or side hustle paid in Bitcoin. • Nostr: Engaging, posting, or contributing to communities. • Streaming: Providing value in podcasts or live content. • Rewards Apps: Using tools like Fold or other Bitcoin cashback services.
Every sat stacks up, and over time, those seemingly small earnings can become life-changing.
The Fun of Stacking Sats
Part of the magic of Bitcoin is the journey. Watching your small daily efforts compound into something meaningful is both empowering and exciting. So whether you’re earning sats, stacking on dips, or getting tipped on Nostr—have fun. Celebrate every sat. You’re building a future on a foundation of hard work and a revolutionary currency.
The Bitcoin ride is just getting started. Hold tight, stack consistently, and enjoy the journey to financial sovereignty!

2025-02-25 03:55:08Here’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.

2025-04-09 21:19:39DAOs promised decentralization. They offered a system where every member could influence a project's direction, where money and power were transparently distributed, and decisions were made through voting. All of it recorded immutably on the blockchain, free from middlemen.
But something didn’t work out. In practice, most DAOs haven’t evolved into living, self-organizing organisms. They became something else: clubs where participation is unevenly distributed. Leaders remained - only now without formal titles. They hold influence through control over communications, task framing, and community dynamics. Centralization still exists, just wrapped in a new package.
But there's a second, less obvious problem. Crowds can’t create strategy. In DAOs, people vote for what "feels right to the majority." But strategy isn’t about what feels good - it’s about what’s necessary. Difficult, unpopular, yet forward-looking decisions often fail when put to a vote. A founder’s vision is a risk. But in healthy teams, it’s that risk that drives progress. In DAOs, risk is almost always diluted until it becomes something safe and vague.
Instead of empowering leaders, DAOs often neutralize them. This is why many DAOs resemble consensus machines. Everyone talks, debates, and participates, but very little actually gets done. One person says, “Let’s jump,” and five others respond, “Let’s discuss that first.” This dynamic might work for open forums, but not for action.
Decentralization works when there’s trust and delegation, not just voting. Until DAOs develop effective systems for assigning roles, taking ownership, and acting with flexibility, they will keep losing ground to old-fashioned startups led by charismatic founders with a clear vision.
We’ve seen this in many real-world cases. Take MakerDAO, one of the most mature and technically sophisticated DAOs. Its governance token (MKR) holders vote on everything from interest rates to protocol upgrades. While this has allowed for transparency and community involvement, the process is often slow and bureaucratic. Complex proposals stall. Strategic pivots become hard to implement. And in 2023, a controversial proposal to allocate billions to real-world assets passed only narrowly, after months of infighting - highlighting how vision and execution can get stuck in the mud of distributed governance.
On the other hand, Uniswap DAO, responsible for the largest decentralized exchange, raised governance participation only after launching a delegation system where token holders could choose trusted representatives. Still, much of the activity is limited to a small group of active contributors. The vast majority of token holders remain passive. This raises the question: is it really community-led, or just a formalized power structure with lower transparency?
Then there’s ConstitutionDAO, an experiment that went viral. It raised over $40 million in days to try and buy a copy of the U.S. Constitution. But despite the hype, the DAO failed to win the auction. Afterwards, it struggled with refund logistics, communication breakdowns, and confusion over governance. It was a perfect example of collective enthusiasm without infrastructure or planning - proof that a DAO can raise capital fast but still lack cohesion.
Not all efforts have failed. Projects like Gitcoin DAO have made progress by incentivizing small, individual contributions. Their quadratic funding mechanism rewards projects based on the number of contributors, not just the size of donations, helping to elevate grassroots initiatives. But even here, long-term strategy often falls back on a core group of organizers rather than broad community consensus.
The pattern is clear: when the stakes are low or the tasks are modular, DAOs can coordinate well. But when bold moves are needed—when someone has to take responsibility and act under uncertainty DAOs often freeze. In the name of consensus, they lose momentum.
That’s why the organization of the future can’t rely purely on decentralization. It must encourage individual initiative and the ability to take calculated risks. People need to see their contribution not just as a vote, but as a role with clear actions and expected outcomes. When the situation demands, they should be empowered to act first and present the results to the community afterwards allowing for both autonomy and accountability. That’s not a flaw in the system. It’s how real progress happens.

2024-12-03 01:23:32Running your own Bitcoin node is one of the most powerful actions you can take to secure financial sovereignty and protect the network’s decentralization.
Bitcoin nodes independently verify transactions and enforce consensus rules, ensuring no single entity—be it governments, corporations, or influential players like BlackRock or Michael Saylor—can dictate how Bitcoin evolves.
Here’s why it matters 👇🏽
1. Decentralization Is Freedom
A network is only as decentralized as its participants. When you run a node, you become a part of the consensus mechanism that ensures Bitcoin remains neutral, censorship-resistant, and immune to centralized control.
2. Verification, Not Trust
Bitcoin’s power lies in its ability to eliminate the need for trust. By running a node, you verify every transaction and block yourself, instead of relying on others who may have vested interests. This ensures you’re transacting on the Bitcoin network as it was designed—not on a version compromised by corporate or governmental interests.
3. Preventing Centralized Upgrades
Players like BlackRock and influential figures might push for changes to Bitcoin that align with their agendas, potentially undermining its core principles. Running your own node gives you the power to reject unwanted upgrades and stick to Bitcoin’s original ethos.
4. Strengthening the Network
The more nodes in the network, the more robust and resistant it becomes to attacks or collusion by centralized entities. Your node helps secure this public good for everyone.
Bitcoin is a tool for freedom, but that freedom only lasts if we actively protect it. Running a node is not just a technical act—it’s a declaration of independence. Don’t let the promise of Bitcoin be steered by the powerful. Take control. Verify. Secure your sovereignty.

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

2025-02-14 23:24:37intro
The Russian state made me a Bitcoiner. In 1991, it devalued my grandmother's hard-earned savings. She worked tirelessly in the kitchen of a dining car on the Moscow–Warsaw route. Everything she had saved for my sister and me to attend university vanished overnight. This story is similar to what many experienced, including Wences Casares. The pain and injustice of that time became my first lessons about the fragility of systems and the value of genuine, incorruptible assets, forever changing my perception of money and my trust in government promises.
In 2014, I was living in Moscow, running a trading business, and frequently traveling to China. One day, I learned about the Cypriot banking crisis and the possibility of moving money through some strange thing called Bitcoin. At the time, I didn’t give it much thought. Returning to the idea six months later, as a business-oriented geek, I eagerly began studying the topic and soon dove into it seriously.
I spent half a year reading articles on a local online journal, BitNovosti, actively participating in discussions, and eventually joined the editorial team as a translator. That’s how I learned about whitepapers, decentralization, mining, cryptographic keys, and colored coins. About Satoshi Nakamoto, Silk Road, Mt. Gox, and BitcoinTalk. Over time, I befriended the journal’s owner and, leveraging my management experience, later became an editor. I was drawn to the crypto-anarchist stance and commitment to decentralization principles. We wrote about the economic, historical, and social preconditions for Bitcoin’s emergence, and it was during this time that I fully embraced the idea.
It got to the point where I sold my apartment and, during the market's downturn, bought 50 bitcoins, just after the peak price of $1,200 per coin. That marked the beginning of my first crypto winter. As an editor, I organized workflows, managed translators, developed a YouTube channel, and attended conferences in Russia and Ukraine. That’s how I learned about Wences Casares and even wrote a piece about him. I also met Mikhail Chobanyan (Ukrainian exchange Kuna), Alexander Ivanov (Waves project), Konstantin Lomashuk (Lido project), and, of course, Vitalik Buterin. It was a time of complete immersion, 24/7, and boundless hope.
After moving to the United States, I expected the industry to grow rapidly, attended events, but the introduction of BitLicense froze the industry for eight years. By 2017, it became clear that the industry was shifting toward gambling and creating tokens for the sake of tokens. I dismissed this idea as unsustainable. Then came a new crypto spring with the hype around beautiful NFTs – CryptoPunks and apes.
I made another attempt – we worked on a series called Digital Nomad Country Club, aimed at creating a global project. The proceeds from selling images were intended to fund the development of business tools for people worldwide. However, internal disagreements within the team prevented us from completing the project.
With Trump’s arrival in 2025, hope was reignited. I decided that it was time to create a project that society desperately needed. As someone passionate about history, I understood that destroying what exists was not the solution, but leaving everything as it was also felt unacceptable. You can’t destroy the system, as the fiery crypto-anarchist voices claimed.
With an analytical mindset (IQ 130) and a deep understanding of the freest societies, I realized what was missing—not only in Russia or the United States but globally—a Bitcoin-native system for tracking debts and financial interactions. This could return control of money to ordinary people and create horizontal connections parallel to state systems. My goal was to create, if not a Bitcoin killer app, then at least to lay its foundation.
At the inauguration event in New York, I rediscovered the Nostr project. I realized it was not only technologically simple and already quite popular but also perfectly aligned with my vision. For the past month and a half, using insights and experience gained since 2014, I’ve been working full-time on this project.

@ daa41bed:88f54153
2025-02-09 16:50:04There has been a good bit of discussion on Nostr over the past few days about the merits of zaps as a method of engaging with notes, so after writing a rather lengthy article on the pros of a strategic Bitcoin reserve, I wanted to take some time to chime in on the much more fun topic of digital engagement.
Let's begin by defining a couple of things:
Nostr is a decentralized, censorship-resistance protocol whose current biggest use case is social media (think Twitter/X). Instead of relying on company servers, it relies on relays that anyone can spin up and own their own content. Its use cases are much bigger, though, and this article is hosted on my own relay, using my own Nostr relay as an example.
Zap is a tip or donation denominated in sats (small units of Bitcoin) sent from one user to another. This is generally done directly over the Lightning Network but is increasingly using Cashu tokens. For the sake of this discussion, how you transmit/receive zaps will be irrelevant, so don't worry if you don't know what Lightning or Cashu are.
If we look at how users engage with posts and follows/followers on platforms like Twitter, Facebook, etc., it becomes evident that traditional social media thrives on engagement farming. The more outrageous a post, the more likely it will get a reaction. We see a version of this on more visual social platforms like YouTube and TikTok that use carefully crafted thumbnail images to grab the user's attention to click the video. If you'd like to dive deep into the psychology and science behind social media engagement, let me know, and I'd be happy to follow up with another article.
In this user engagement model, a user is given the option to comment or like the original post, or share it among their followers to increase its signal. They receive no value from engaging with the content aside from the dopamine hit of the original experience or having their comment liked back by whatever influencer they provide value to. Ad revenue flows to the content creator. Clout flows to the content creator. Sales revenue from merch and content placement flows to the content creator. We call this a linear economy -- the idea that resources get created, used up, then thrown away. Users create content and farm as much engagement as possible, then the content is forgotten within a few hours as they move on to the next piece of content to be farmed.
What if there were a simple way to give value back to those who engage with your content? By implementing some value-for-value model -- a circular economy. Enter zaps.
Unlike traditional social media platforms, Nostr does not actively use algorithms to determine what content is popular, nor does it push content created for active user engagement to the top of a user's timeline. Yes, there are "trending" and "most zapped" timelines that users can choose to use as their default, but these use relatively straightforward engagement metrics to rank posts for these timelines.
That is not to say that we may not see clients actively seeking to refine timeline algorithms for specific metrics. Still, the beauty of having an open protocol with media that is controlled solely by its users is that users who begin to see their timeline gamed towards specific algorithms can choose to move to another client, and for those who are more tech-savvy, they can opt to run their own relays or create their own clients with personalized algorithms and web of trust scoring systems.
Zaps enable the means to create a new type of social media economy in which creators can earn for creating content and users can earn by actively engaging with it. Like and reposting content is relatively frictionless and costs nothing but a simple button tap. Zaps provide active engagement because they signal to your followers and those of the content creator that this post has genuine value, quite literally in the form of money—sats.
I have seen some comments on Nostr claiming that removing likes and reactions is for wealthy people who can afford to send zaps and that the majority of people in the US and around the world do not have the time or money to zap because they have better things to spend their money like feeding their families and paying their bills. While at face value, these may seem like valid arguments, they, unfortunately, represent the brainwashed, defeatist attitude that our current economic (and, by extension, social media) systems aim to instill in all of us to continue extracting value from our lives.
Imagine now, if those people dedicating their own time (time = money) to mine pity points on social media would instead spend that time with genuine value creation by posting content that is meaningful to cultural discussions. Imagine if, instead of complaining that their posts get no zaps and going on a tirade about how much of a victim they are, they would empower themselves to take control of their content and give value back to the world; where would that leave us? How much value could be created on a nascent platform such as Nostr, and how quickly could it overtake other platforms?
Other users argue about user experience and that additional friction (i.e., zaps) leads to lower engagement, as proven by decades of studies on user interaction. While the added friction may turn some users away, does that necessarily provide less value? I argue quite the opposite. You haven't made a few sats from zaps with your content? Can't afford to send some sats to a wallet for zapping? How about using the most excellent available resource and spending 10 seconds of your time to leave a comment? Likes and reactions are valueless transactions. Social media's real value derives from providing monetary compensation and actively engaging in a conversation with posts you find interesting or thought-provoking. Remember when humans thrived on conversation and discussion for entertainment instead of simply being an onlooker of someone else's life?
If you've made it this far, my only request is this: try only zapping and commenting as a method of engagement for two weeks. Sure, you may end up liking a post here and there, but be more mindful of how you interact with the world and break yourself from blind instinct. You'll thank me later.

2025-02-05 17:47:16I 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:
- 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.
- 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."

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

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

2025-03-12 00:40:25Before 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.

2025-02-01 11:16:04Federal employees must remove pronouns from email signatures by the end of the day. This directive comes from internal memos tied to two executive orders signed by Donald Trump. The orders target diversity and equity programs within the government.
CDC, Department of Transportation, and Department of Energy employees were affected. Staff were instructed to make changes in line with revised policy prohibiting certain language.
One CDC employee shared frustration, stating, “In my decade-plus years at CDC, I've never been told what I can and can't put in my email signature.” The directive is part of a broader effort to eliminate DEI initiatives from federal discourse.

2025-05-20 18:26:00The term "Ponzi scheme" is named after Charles Ponzi, who famously perpetrated a large-scale fraudulent investment scheme in the 1920s. While earlier instances of similar schemes existed, Ponzi's notoriety and scale cemented the name in popular usage.
There are some detailed of ponzi history: Pre-Ponzi; Adele Spitzeder (1869-1872): In Germany, Spitzeder used a Ponzi-like scheme to defraud investors.
Sarah Howe (1880s): In the United States, Howe used a scheme called "Ladies Deposit" to attract female investors with high interest rates, ultimately stealing their money.
Literary Precedents: Charles Dickens novels "Martin Chuzzlewit" (1844) and "Little Dorrit" (1857) included characters and storylines that featured similar fraudulent investment schemes.
The Charles Ponzi Scheme (1920s): Ponzi's scheme involved claiming to buy international postal reply coupons in Europe, redeem them for more expensive US postage stamps, and generate high profits.
The Reality: In reality, he diverted money from new investors to pay off earlier investors, rather than using it for legitimate business.
The Rise and Fall: Ponzi amassed significant wealth, drawing in around 30,000 investors and collecting over $8 million in just seven months. However, the scheme collapsed due to its unsustainable nature, and Ponzi was eventually convicted and served time in prison.
Impact and Legacy: Ponzi's scheme gained widespread publicity, both during its operation and after its collapse. This notoriety led to the scheme being named after him, and the term "Ponzi scheme" became synonymous with this type of fraudulent investment scam.
Ponzi scheme have cause more harm than good in world at large and it is a fraudulent investment scheme. Say no to ponzi scheme! Say no to ponzi scheme!!

2025-02-27 21:32:12GA, 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.

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

2025-01-29 05:55:02The land that belongs to the indigenous peoples of Russia has been seized by a gang of killers who have unleashed a war of extermination. They wipe out anyone who refuses to conform to their rules. Those who disagree and stay behind are tortured and killed in prisons and labor camps. Those who flee lose their homeland, dissolve into foreign cultures, and fade away. And those who stand up to protect their people are attacked by the misled and deceived. The deceived die for the unchecked greed of a single dictator—thousands from both sides, people who just wanted to live, raise their kids, and build a future.
Now, they are forced to make an impossible choice: abandon their homeland or die. Some perish on the battlefield, others lose themselves in exile, stripped of their identity, scattered in a world that isn’t theirs.
There’s been endless debate about how to fix this, how to clear the field of the weeds that choke out every new sprout, every attempt at change. But the real problem? We can’t play by their rules. We can’t speak their language or use their weapons. We stand for humanity, and no matter how righteous our cause, we will not multiply suffering. Victory doesn’t come from matching the enemy—it comes from staying ahead, from using tools they haven’t mastered yet. That’s how wars are won.
Our only resource is the will of the people to rewrite the order of things. Historian Timothy Snyder once said that a nation cannot exist without a city. A city is where the most active part of a nation thrives. But the cities are occupied. The streets are watched. Gatherings are impossible. They control the money. They control the mail. They control the media. And any dissent is crushed before it can take root.
So I started asking myself: How do we stop this fragmentation? How do we create a space where people can rebuild their connections when they’re ready? How do we build a self-sustaining network, where everyone contributes and benefits proportionally, while keeping their freedom to leave intact? And more importantly—how do we make it spread, even in occupied territory?
In 2009, something historic happened: the internet got its own money. Thanks to Satoshi Nakamoto, the world took a massive leap forward. Bitcoin and decentralized ledgers shattered the idea that money must be controlled by the state. Now, to move or store value, all you need is an address and a key. A tiny string of text, easy to carry, impossible to seize.
That was the year money broke free. The state lost its grip. Its biggest weapon—physical currency—became irrelevant. Money became purely digital.
The internet was already a sanctuary for information, a place where people could connect and organize. But with Bitcoin, it evolved. Now, value itself could flow freely, beyond the reach of authorities.
Think about it: when seedlings are grown in controlled environments before being planted outside, they get stronger, survive longer, and bear fruit faster. That’s how we handle crops in harsh climates—nurture them until they’re ready for the wild.
Now, picture the internet as that controlled environment for ideas. Bitcoin? It’s the fertile soil that lets them grow. A testing ground for new models of interaction, where concepts can take root before they move into the real world. If nation-states are a battlefield, locked in a brutal war for territory, the internet is boundless. It can absorb any number of ideas, any number of people, and it doesn’t run out of space.
But for this ecosystem to thrive, people need safe ways to communicate, to share ideas, to build something real—without surveillance, without censorship, without the constant fear of being erased.
This is where Nostr comes in.
Nostr—"Notes and Other Stuff Transmitted by Relays"—is more than just a messaging protocol. It’s a new kind of city. One that no dictator can seize, no corporation can own, no government can shut down.
It’s built on decentralization, encryption, and individual control. Messages don’t pass through central servers—they are relayed through independent nodes, and users choose which ones to trust. There’s no master switch to shut it all down. Every person owns their identity, their data, their connections. And no one—no state, no tech giant, no algorithm—can silence them.
In a world where cities fall and governments fail, Nostr is a city that cannot be occupied. A place for ideas, for networks, for freedom. A city that grows stronger the more people build within it.

2025-05-20 15:51:33Introduction
It is becoming increasingly evident that sunlight is an essential nutrient for the body. To be more precise, the various wavelengths coming from the sun provide different benefits to the body, and each play a vital role in human health. Even more so, they work in concert with one another, as one wavelength may help reduce the potentially harmful effects of another. Benefits are maximized and harm reduced when we are exposed to the full breadth of this rainbow. This article will attempt to shed light on these various benefits and synergies.
To put this discussion into context, it is important to consider the overall health benefits of sunlight exposure. In a Swedish study that followed 29,000 women over 20 years, it was found that the mortality rate was doubled in those who avoided sun exposure when compared to those that didn’t (Lindqvist et al. 2016). Women who avoided the sun were twice as likely to die, primarily from cardiovascular disease, and there was no difference between death from malignant melanoma between the two groups (Lindqvist et al. 2016).
To understand why sunlight is so beneficial to health, it is important to make clear the diverse range of wavelengths that come from the sun. We typically think of the sun as a provider of both visible light and warmth. However, the spectrum of light visible to the human eye is a narrow band of the wavelengths actually emitted by the sun.
As wavelengths become shorter, visible light becomes more blue. Beyond the visible spectrum on the blue end, we arrive at ultraviolet (UV) light. On the other end of the spectrum are the longer red wavelengths. Outside of the visible window on the red side is infrared (IR) light, which provides heat. For helpful context, consider how shorter wavelengths have a harder time penetrating our atmosphere. So, the skies of dawn and dusk are predominately filled with red and near-infrared (NIR) light, while the middle of the day contains more blue and UV light. The bulk of wavelengths from the sun throughout the day are on the NIR end. The entire spectrum of visible and non-visible light between UV and IR plays critical roles in human health, especially towards mitochondrial health and metabolism. To summarize these benefits and provide a general overview for the following article, the benefits are as follows:
- UV – aids in the production of vitamin D and melanin, but also causes DNA damage
- Vitamin D improves immune system function and can repair DNA damage
- Melanin stores electrons for use within mitochondria
- Blue – involved in our circadian rhythm as the absence of blue light triggers the production of melatonin, an important antioxidant.
- Near-infrared (NIR) – improves mitochondria function and energy production while also protecting us from the harms of blue and UV light.
Ultraviolet Light
Let’s begin with a discussion around the widely misunderstood light of UV. UV is often viewed as a dangerous form of light, given that it can cause DNA damage and lead to cancer. While true, this myopic point of view ignores the crucial benefits of UV light. UV light produces vitamin D, which counteracts the DNA damage caused by UV while providing many other benefits. Additionally, UV light triggers the production of melanin, which aids in mitochondrial function. Like all physiological processes in the body that are vital to survival, there is a release of POMC-derived endorphins when skin comes into contact with UV light (Fell et al. 2014). Any person likely reading this article can agree that sitting under the sun simply feels amazing. We are drawn to it in a deeply meaningful sense.
Vitamin D is one of the most important chemicals regarding health, and it is poorly named. The term ‘vitamin’ refers to a compound that is important for health but cannot be adequately made within the body and must be retrieved externally. Peoples of the Northern and Southern hemisphere who are exposed to less UV light during winter would, for example, historically retrieve their vitamin D from foods such as oily fish, seal blubber, whale blubber, and polar bear liver (Wacker and Holick 2013). In a similar way, vitamin D was given its name 100 years ago when it was found that cod-liver oil was capable of curing rickets, when it was found that the so-called vitamin could promote calcium deposition in bones (McCollum et al. 1922). It was only until much later, in 1981, when scientists discovered that human skin could also synthesize vitamin D (M. F. Holick 1981). A majority of human vitamin D is produced by the skin when exposed to UVB (280 – 315 nm), while a minor amount is gained through food (Prietl et al. 2013; Wacker and Holick 2013). Most cells and organs in the human body have vitamin D receptors and many organs also have the ability to produce it, this speaks to the incredibly important nature of this compound towards our health (Prietl et al. 2013; Wacker and Holick 2013). Vitamin D deficiency has been associated with various types of cancer, autoimmune disorders, type 1 diabetes mellitus, multiple sclerosis (MS), cardiovascular disease, and even schizophrenia (Michael F. Holick 2007; Wacker and Holick 2013). Multiple studies have also found that vitamin D deficiency increases all-cause mortality (Garland et al. 2014; Yang et al. 2011; Chowdhury et al. 2014).
Though the historical benefits to vitamin D were attributed mainly to bone health, it is far more important. Vitamin D plays a critical role in protecting against invasive pathogens, reducing autoimmunity, and maintaining overall health (Wimalawansa 2023). Regarding immunity, one way it does this is by causing a shift away from proinflammatory responses to one more centered around T cell activation (Prietl et al. 2013). Vitamin D has therefore been shown to benefit other disorders that are related to immunity, such as a study that found vitamin D supplementation during pregnancy reduced asthmatic symptoms in children (Litonjua et al. 2016). That being said, it is important to highlight how there is no substitution for natural sunlight as a means of getting vitamin D. Naturally produced vitamin D from the skin lasts 2-3 times longer in the body (Wacker and Holick 2013). This is one of many likely reasons why the natural avenue should always be preferred over the supplemental. A similar line of reasoning follows in methods of getting UV light, as natural sun exposure leads to a decrease of all-cause mortality while the use of artificial tanning beds has been shown to increase all-cause and cancer mortality (Yang et al. 2011). More on why this likely occurs later.
Beyond vitamin D’s benefits to the immune system, it is important to focus on the compound’s role in mitochondrial health. In a previous article I wrote titled “Sunlight and Health”, I delve deeper into the importance of mitochondria and the science of how they work. In simplicity, imagine how all life on earth centers around energy. The sun provides energy to the earth, and the plethora of life on earth harness and facilitate the flow of that energy. Plants and animals share a symbiotic relationship within this system. Plants, through photosynthesis, take in sunlight, CO2, and water and create a glucose precursor and oxygen. This occurs within the chloroplast of plant cells. Within human cells, we have mitochondria. Our mitochondria, in turn, take in oxygen and glucose and produce CO2, water, and energy for our bodies in the form of ATP. What the plant breathes out, we breathe in, and vice versa. Mitochondria are central to all animal life on earth, and the ATP produced is central to all physiologic function. If your mitochondria are unhealthy, you are unhealthy and will experience disease.
Vitamin D plays a role in mitochondrial health at a DNA level. Our cells have DNA, which we inherited from our mother and father. On top of that, the mitochondria within our cells have their own set of DNA (mtDNA). Our mitochondria come from our mother’s egg, and therefore our mtDNA always is inherited from our mother. UV light can cause damage to both our DNA and mtDNA (Birch-Machin, Russell, and Latimer 2013). This is what gives UV light the ability to cause cancer. Additionally, damage to the mtDNA within our mitochondria can lead to mitochondrial dysfunction. The more poorly our mitochondria function, the less energy we produce for our cells, and the less healthy our cells become. There is research being developed that suggests the role of vitamin D is to counterbalance this danger by regulating gene transcription and reducing mtDNA damage. A mouse study conducted in 2011, for example, found that different shapes of vitamin D reduce the development of tumors in mice following UV exposure (Dixon et al. 2011). It is not unlike nature to create a system of checks and balances, to ensure that the damaging effects of UV light are counterbalanced by a compound produced by the body when exposure to that same light.
While vitamin D may be important for mitochondrial health by protecting against mtDNA damage, melanin potentially plays a much larger role. Melanin is the pigment in our skin that make us darker. Not only is the diversity in skin tones across humans due to variations in melanin content, but a tan is also the creation of more melanin. To be more specific, the skin’s exposure to UVA (315-400nm) leads to the creation of melanin (Wicks et al. 2011). The most obvious benefit to the production of melanin, which most people could appreciate, is that the darker or tanner our skin is, the less damage we will receive from UV light. In this way, melanin shares a similar responsibility to vitamin D, where both are protecting the body against the very thing that forms them. Even more crucially however, melanin acts as a battery for the mitochondria.
During cellular respiration, where mitochondria turn oxygen and glucose into energy, electrons are stripped from the glucose for use. In other words, what our mitochondria really need are oxygen and electrons, and the glucose is simply a means to an end. If the mitochondria are the engine, then the electrons are the fuel (assuming you are still breathing). Due to its chemical structure, melanin is a natural reversible oxidation-reduction system (Figge 1939). In other words, it can both store and release electrons. Melanin is therefore a kind of battery, retrieving electrons from various sources, and storing them for future use in our mitochondria as a substitute for food. When stated this way, and considering how food is important because both fats and carbohydrates fuel the body by providing electrons to our mitochondria, one can imagine how vitally important melanin is. Melanin is central towards the availability of electrons for use in our body to produce the energy to live. Without adequate melanin, your mitochondria will starve for fuel and not provide your body with the energy it needs to thrive.
Blue Light
To contextualize the role blue light plays in human health, it is important to revisit an important byproduct of cellular respiration within mitochondria. When mitochondria turn electrons and oxygen into energy, there is a byproduct formed known as reactive oxygen species (ROS). ROS play important roles in the body, but in excess they can cause DNA damage and disrupt various cellular processes. For example, UV light causes cancer due to the ROS generated, and studies have found that blue light does the same in both the skin and eyes (Nakashima, Ohta, and Wolf 2017; Abdouh et al. 2024). This research suggests that excess blue light or blue light in isolation can damage the eyes and cause harm like UV light.
Blue and UV light are predominant during the middle of the day. Though both may cause oxidative stress on the body, the body simultaneously counteracts this damage through melatonin. Think of melatonin as the junk remover for mitochondria. Throughout the day mitochondria produce energy, and ROS is formed. During our nighttime sleep, melatonin plays an important role as an antioxidant and removes the excess ROS (Leon et al. 2004).
The relationship between blue light and melatonin is important. During the day, when blue light is present, our body suppresses the production of melatonin (West et al. 2011). When the sun sets and there is no longer a heavy presence of blue light, our body begins to produce melatonin for sleep. This is a central function for how our body gets tired at night and gets ready for sleep. This is also why artificial light at night, from our modern technology, is harmful to human health because it tricks the body into the continual suppression of melatonin production. Without proper melatonin production, our cells buildup too much ROS and this can cause mitochondrial dysfunction and other sleep related issues.
Beyond the importance of getting good sleep and producing melatonin to remove excess ROS from our cells, the existence of artificial light and excess blue light is problematic during the day as well. As stated previously, blue light causes ROS buildup in both the skin and eyes (Nakashima, Ohta, and Wolf 2017; Abdouh et al. 2024). As with most harms from sunlight, our body has adapted with a backup plan. During the day, when blue and UV light is present, there is simultaneous exposure to NIR light (650-1200nm). Recent research suggests that NIR also counterbalances the harm of blue light by increasing melatonin synthesis in the mitochondria (Tan et al. 2023). This highlights the importance of receiving the full spectrum of light from the sun, as one wavelength counterbalances the damages of the other.
Near-Infrared Light
While indoor living has been commonplace for humans across generations, and modern technology has over saturated our bodies with blue light, some recent changes to our technology have made things worse. Incandescent light bulbs emit NIR light, this is why they got warm. However, LED lights do not emit NIR light. Therefore, where people of past generations were potentially exposed to a lot of artificial light at night, this was counterbalanced by the NIR emitted by those same lightbulbs. Now, modern humans use LEDs and spend 93% of our time indoors with zero exposure to NIR, which is 90% of the light emitted by the sun (Tan et al. 2023).
Not only does NIR light protect our bodies from the damaging consequences of blue light, but it similarly protects us against UV light. As stated previously, NIR may result in the production of melatonin within mitochondria during the day, helping protect against the ROS buildup and mtDNA damage. Additionally, research has also found that NIR light protects from UV light in other ways. For example, a study in 2008 found that pretreating skin with NIR light (660nm) prevented sunburns (Barolet and Boucher 2008). Another study found that red and NIR light (620-690nm) altered gene expression and upregulated DNA repair (Kim et al. 2019). Again, this highlights the theme that the body has produced the means to protect itself from the harms of the sun via other rays emitted. However, the protection from harmful rays is best achieved when exposed to the full spectrum of light wavelengths as they change throughout the day. The light of dawn and dusk is predominately red and NIR. Therefore, this research suggests that being exposed to morning light will protect the body from the potentially cancer-causing effects of the UV light later in the day. A human being who lived outside would naturally be exposed to this spectrum of light every day. However, modern humans may be inside in the morning, go to the beach during the middle of the day, and get sunburned because they do not properly receive the full spectrum of light as nature intended every day.
Lastly, it is important to explore the ways NIR improves mitochondrial function. If electrons are the fuel source for this engine, and melatonin is the junk removal, then NIR is the lubricant. NIR improves the energy output of mitochondria, and there are various hypotheses for how this occurs. One hypothesis is that NIR boosts the functionality of cytochrome c oxidase, one of the chromophores used in the electron transport chain (ETC) of cellular respiration within mitochondria (De Freitas and Hamblin 2016). Another involves NIR light’s ability to modify the viscosity of water which increases the efficiency of the final step in the ETC, the ATP synthase (Sommer, Haddad, and Fecht 2015). ATP synthase can be thought of as a kind of pump that produces ATP, in this way NIR can be thought of almost literally as a lubricant for this pump.
Summary
In summary, the research involving how sunlight affects mitochondrial health highlights the importance of the full spectrum of wavelengths, each of which plays a vital role in human health throughout the day. Having exposure to one, without the other, can lead to imbalances and mitochondrial disease. The red and NIR light in the morning helps our mitochondria produce more energy throughout the day, while also preparing our bodies for the beneficial yet dangerous wavelengths to come. In the middle of the day, we receive much more UV and blue light, which help us produce vitamin D and melanin, both central to health and wellness. Once the sun sets, and blue light is absent, we produce melatonin for sleep. During our sleep, the melatonin removes the dangerous byproducts of our energy-producing day, protecting us from disease and preparing us for the following day. Mitochondria are central to human health and life on earth, and the rays from the sun are central to mitochondrial health.
Respecting nature and its cycles is vital for us humans who are increasingly immersing ourselves in a world dominated by technology. Our ancestors did not have to reconcile with these ideas, because life forced these exposures upon them. If we wish to maintain health in our modern world, we must be able to find balance. Even though some might think they can escape into the virtual world, our bodies will always and forever be connected and reliant upon the natural one.

2025-02-13 06:16:49My 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.”

2025-05-20 15:50:48For 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.

2025-05-21 02:35:36如果比特币发明了真正的钱,那么 Crypto 是什么?
引言
比特币诞生之初就以“数字黄金”姿态示人,被支持者誉为人类历史上第一次发明了真正意义上的钱——一种不依赖国家信用、总量恒定且不可篡改的硬通货。然而十多年过去,比特币之后蓬勃而起的加密世界(Crypto)已经远超“货币”范畴:从智能合约平台到去中心组织,从去央行的稳定币到戏谑荒诞的迷因币,Crypto 演化出一个丰富而混沌的新生态。这不禁引发一个根本性的追问:如果说比特币解决了“真金白银”的问题,那么 Crypto 又完成了什么发明?
Crypto 与政治的碰撞:随着Crypto版图扩张,全球政治势力也被裹挟进这场金融变革洪流(示意图)。比特币的出现重塑了货币信用,但Crypto所引发的却是一场更深刻的政治与治理结构实验。从华尔街到华盛顿,从散户论坛到主权国家,越来越多人意识到:Crypto不只是技术或金融现象,而是一种全新的政治表达结构正在萌芽。正如有激进论者所断言的:“比特币发明了真正的钱,而Crypto则在发明新的政治。”价格K线与流动性曲线,或许正成为这个时代社群意志和社会价值观的新型投射。
冲突结构:当价格挑战选票
传统政治中,选票是人民意志的载体,一人一票勾勒出民主治理的正统路径。而在链上的加密世界里,骤升骤降的价格曲线和真金白银的买卖行为却扮演起了选票的角色:资金流向成了民意走向,市场多空成为立场表决。价格行为取代选票,这听来匪夷所思,却已在Crypto社群中成为日常现实。每一次代币的抛售与追高,都是社区对项目决策的即时“投票”;每一根K线的涨跌,都折射出社区意志的赞同或抗议。市场行为本身承担了决策权与象征权——价格即政治,正在链上蔓延。
这一新生政治形式与旧世界的民主机制形成了鲜明冲突。bitcoin.org中本聪在比特币白皮书中提出“一CPU一票”的工作量证明共识,用算力投票取代了人为决策bitcoin.org。而今,Crypto更进一步,用资本市场的涨跌来取代传统政治的选举。支持某项目?直接购入其代币推高市值;反对某提案?用脚投票抛售资产。相比漫长的选举周期和层层代议制,链上市场提供了近乎实时的“公投”机制。但这种机制也引发巨大争议:资本的投票天然偏向持币多者(富者)的意志,是否意味着加密政治更为金权而非民权?持币多寡成为影响力大小,仿佛选举演变成了“一币一票”,巨鲸富豪俨然掌握更多话语权。这种与民主平等原则的冲突,成为Crypto政治形式饱受质疑的核心张力之一。
尽管如此,我们已经目睹市场投票在Crypto世界塑造秩序的威力:2016年以太坊因DAO事件分叉时,社区以真金白银“投票”决定了哪条链获得未来。arkhamintelligence.com结果是新链以太坊(ETH)成为主流,其市值一度超过2,800亿美元,而坚持原则的以太经典(ETC)市值不足35亿美元,不及前者的八十分之一arkhamintelligence.com。市场选择清楚地昭示了社区的政治意志。同样地,在比特币扩容之争、各类硬分叉博弈中,无不是由投资者和矿工用资金与算力投票,胜者存续败者黯然。价格成为裁决纷争的最终选票,冲击着传统“选票决胜”的政治理念。Crypto的价格民主,与现代代议民主正面相撞,激起当代政治哲思中前所未有的冲突火花。
治理与分配
XRP对决SEC成为了加密世界“治理与分配”冲突的经典战例。2020年底,美国证券交易委员会(SEC)突然起诉Ripple公司,指控其发行的XRP代币属于未注册证券,消息一出直接引爆市场恐慌。XRP价格应声暴跌,一度跌去超过60%,最低触及0.21美元coindesk.com。曾经位居市值前三的XRP险些被打入谷底,监管的强硬姿态似乎要将这个项目彻底扼杀。
然而XRP社区没有选择沉默。 大批长期持有者组成了自称“XRP军团”(XRP Army)的草根力量,在社交媒体上高调声援Ripple,对抗监管威胁。面对SEC的指控,他们集体发声,质疑政府选择性执法,声称以太坊当年发行却“逍遥法外”,只有Ripple遭到不公对待coindesk.com。正如《福布斯》的评论所言:没人预料到愤怒的加密散户投资者会掀起法律、政治和社交媒体领域的‘海啸式’反击,痛斥监管机构背弃了保护投资者的承诺crypto-law.us。这种草根抵抗监管的话语体系迅速形成:XRP持有者不但在网上掀起舆论风暴,还采取实际行动向SEC施压。他们发起了请愿,抨击SEC背离保护投资者初衷、诉讼给个人投资者带来巨大伤害,号召停止对Ripple的上诉纠缠——号称这是在捍卫全球加密用户的共同利益bitget.com。一场由民间主导的反监管运动就此拉开帷幕。
Ripple公司则选择背水一战,拒绝和解,在法庭上与SEC针锋相对地鏖战了近三年之久。Ripple坚称XRP并非证券,不应受到SEC管辖,即使面临沉重法律费用和业务压力也不妥协。2023年,这场持久战迎来了标志性转折:美国法庭作出初步裁决,认定XRP在二级市场的流通不构成证券coindesk.com。这一胜利犹如给沉寂已久的XRP注入强心针——消息公布当天XRP价格飙涨近一倍,盘中一度逼近1美元大关coindesk.com。沉重监管阴影下苟延残喘的项目,凭借司法层面的突破瞬间重获生机。这不仅是Ripple的胜利,更被支持者视为整个加密行业对SEC强权的一次胜仗。
XRP的对抗路线与某些“主动合规”的项目形成了鲜明对比。 稳定币USDC的发行方Circle、美国最大合规交易所Coinbase等选择了一条迎合监管的道路:它们高调拥抱现行法规,希望以合作换取生存空间。然而现实却给了它们沉重一击。USDC稳定币在监管风波中一度失去美元锚定,哪怕Circle及时披露储备状况也无法阻止恐慌蔓延,大批用户迅速失去信心,短时间内出现数十亿美元的赎回潮blockworks.co。Coinbase则更为直接:即便它早已注册上市、反复向监管示好,2023年仍被SEC指控为未注册证券交易所reuters.com,卷入漫长诉讼漩涡。可见,在迎合监管的策略下,这些机构非但未能换来监管青睐,反而因官司缠身或用户流失而丧失市场信任。 相比之下,XRP以对抗求生存的路线反而赢得了投资者的眼光:价格的涨跌成为社区投票的方式,抗争的勇气反过来强化了市场对它的信心。
同样引人深思的是另一种迥异的治理路径:技术至上的链上治理。 以MakerDAO为代表的去中心化治理模式曾被寄予厚望——MKR持币者投票决策、算法维持稳定币Dai的价值,被视为“代码即法律”的典范。然而,这套纯技术治理在市场层面却未能形成广泛认同,亦无法激发群体性的情绪动员。复杂晦涩的机制使得普通投资者难以参与其中,MakerDAO的治理讨论更多停留在极客圈子内部,在社会大众的政治对话中几乎听不见它的声音。相比XRP对抗监管所激发的铺天盖地关注,MakerDAO的治理实验显得默默无闻、难以“出圈”。这也说明,如果一种治理实践无法连接更广泛的利益诉求和情感共鸣,它在社会政治层面就难以形成影响力。
XRP之争的政治象征意义由此凸显: 它展示了一条“以市场对抗国家”的斗争路线,即通过代币价格的集体行动来回应监管权力的施压。在这场轰动业界的对决中,价格即是抗议的旗帜,涨跌映射着政治立场。XRP对SEC的胜利被视作加密世界向旧有权力宣告的一次胜利:资本市场的投票器可以撼动监管者的强权。这种“价格即政治”的张力,正是Crypto世界前所未有的社会实验:去中心化社区以市场行为直接对抗国家权力,在无形的价格曲线中凝聚起政治抗争的力量,向世人昭示加密货币不仅有技术和资本属性,更蕴含着不可小觑的社会能量和政治意涵。
不可归零的政治资本
Meme 币的本质并非廉价或易造,而在于其构建了一种“无法归零”的社群生存结构。 对于传统观点而言,多数 meme 币只是短命的投机游戏:价格暴涨暴跌后一地鸡毛,创始人套现跑路,投资者血本无归,然后“大家转去炒下一个”theguardian.com。然而,meme 币社群的独特之处在于——失败并不意味着终结,而更像是运动的逗号而非句号。一次币值崩盘后,持币的草根们往往并未散去;相反,他们汲取教训,准备东山再起。这种近乎“不死鸟”的循环,使得 meme 币运动呈现出一种数字政治循环的特质:价格可以归零,但社群的政治热情和组织势能不归零。正如研究者所指出的,加密领域中的骗局、崩盘等冲击并不会摧毁生态,反而成为让系统更加强韧的“健康应激”,令整个行业在动荡中变得更加反脆弱cointelegraph.com。对应到 meme 币,每一次暴跌和重挫,都是社群自我进化、卷土重来的契机。这个去中心化群体打造出一种自组织的安全垫,失败者得以在瓦砾上重建家园。对于草根社群、少数派乃至体制的“失败者”而言,meme 币提供了一个永不落幕的抗争舞台,一种真正反脆弱的政治性。正因如此,我们看到诸多曾被嘲笑的迷因项目屡败屡战:例如 Dogecoin 自2013年问世后历经八年沉浮,早已超越玩笑属性,成为互联网史上最具韧性的迷因之一frontiersin.org;支撑 Dogecoin 的正是背后强大的迷因文化和社区意志,它如同美国霸权支撑美元一样,为狗狗币提供了“永不中断”的生命力frontiersin.org。
“复活权”的数字政治意涵
这种“失败-重生”的循环结构蕴含着深刻的政治意涵:在传统政治和商业领域,一个政党选举失利或一家公司破产往往意味着清零出局,资源散尽、组织瓦解。然而在 meme 币的世界,社群拥有了一种前所未有的“复活权”。当项目崩盘,社区并不必然随之消亡,而是可以凭借剩余的人心和热情卷土重来——哪怕换一个 token 名称,哪怕重启一条链,运动依然延续。正如 Cheems 项目的核心开发者所言,在几乎无人问津、技术受阻的困境下,大多数人可能早已卷款走人,但 “CHEEMS 社区没有放弃,背景、技术、风投都不重要,重要的是永不言弃的精神”cointelegraph.com。这种精神使得Cheems项目起死回生,社区成员齐声宣告“我们都是 CHEEMS”,共同书写历史cointelegraph.com。与传统依赖风投和公司输血的项目不同,Cheems 完全依靠社区的信念与韧性存续发展,体现了去中心化运动的真谛cointelegraph.com。这意味着政治参与的门槛被大大降低:哪怕没有金主和官方背书,草根也能凭借群体意志赋予某个代币新的生命。对于身处社会边缘的群体来说,meme 币俨然成为自组织的安全垫和重新集结的工具。难怪有学者指出,近期涌入meme币浪潮的主力,正是那些对现实失望但渴望改变命运的年轻人theguardian.com——“迷茫的年轻人,想要一夜暴富”theguardian.com。meme币的炒作表面上看是投机赌博,但背后蕴含的是草根对既有金融秩序的不满与反抗:没有监管和护栏又如何?一次失败算不得什么,社区自有后路和新方案。这种由底层群众不断试错、纠错并重启的过程,本身就是一种数字时代的新型反抗运动和群众动员机制。
举例而言,Terra Luna 的沉浮充分展现了这种“复活机制”的政治力量。作为一度由风投资本热捧的项目,Luna 币在2022年的崩溃本可被视作“归零”的失败典范——稳定币UST瞬间失锚,Luna币价归零,数十亿美元灰飞烟灭。然而“崩盘”并没有画下休止符。Luna的残余社区拒绝承认失败命运,通过链上治理投票毅然启动新链,“复活”了 Luna 代币,再次回到市场交易reuters.com。正如 Terra 官方在崩盘后发布的推文所宣称:“我们力量永在社区,今日的决定正彰显了我们的韧性”reuters.com。事实上,原链更名为 Luna Classic 后,大批所谓“LUNC 军团”的散户依然死守阵地,誓言不离不弃;他们自发烧毁巨量代币以缩减供应、推动技术升级,试图让这个一度归零的项目重新燃起生命之火binance.com。失败者并未散场,而是化作一股草根洪流,奋力托举起项目的残迹。经过迷因化的叙事重塑,这场从废墟中重建价值的壮举,成为加密世界中草根政治的经典一幕。类似的案例不胜枚举:曾经被视为笑话的 DOGE(狗狗币)正因多年社群的凝聚而跻身主流币种,总市值一度高达数百亿美元,充分证明了“民有民享”的迷因货币同样可以笑傲市场frontiersin.org。再看最新的美国政治舞台,连总统特朗普也推出了自己的 meme 币 $TRUMP,号召粉丝拿真金白银来表达支持。该币首日即从7美元暴涨至75美元,两天后虽回落到40美元左右,但几乎同时,第一夫人 Melania 又发布了自己的 $Melania 币,甚至连就职典礼的牧师都跟风发行了纪念币theguardian.com!显然,对于狂热的群众来说,一个币的沉浮并非终点,而更像是运动的换挡——资本市场成为政治参与的新前线,你方唱罢我登场,meme 币的群众动员热度丝毫不减。值得注意的是,2024年出现的 Pump.fun 等平台更是进一步降低了这一循环的技术门槛,任何人都可以一键生成自己的 meme 币theguardian.com。这意味着哪怕某个项目归零,剩余的社区完全可以借助此类工具迅速复制一个新币接力,延续集体行动的火种。可以说,在 meme 币的世界里,草根社群获得了前所未有的再生能力和主动权,这正是一种数字时代的群众政治奇观:失败可以被当作梗来玩,破产能够变成重生的序章。
价格即政治:群众投机的新抗争
meme 币现象的兴盛表明:在加密时代,价格本身已成为一种政治表达。这些看似荒诞的迷因代币,将金融市场变成了群众宣泄情绪和诉求的另一个舞台。有学者将此概括为“将公民参与直接转化为了投机资产”cdn-brighterworld.humanities.mcmaster.ca——也就是说,社会运动的热情被注入币价涨跌,政治支持被铸造成可以交易的代币。meme 币融合了金融、技术与政治,通过病毒般的迷因文化激发公众参与,形成对现实政治的某种映射cdn-brighterworld.humanities.mcmaster.caosl.com。当一群草根投入全部热忱去炒作一枚毫无基本面支撑的币时,这本身就是一种大众政治动员的体现:币价暴涨,意味着一群人以戏谑的方式在向既有权威叫板;币价崩盘,也并不意味着信念的消亡,反而可能孕育下一次更汹涌的造势。正如有分析指出,政治类 meme 币的出现前所未有地将群众文化与政治情绪融入市场行情,价格曲线俨然成为民意和趋势的风向标cdn-brighterworld.humanities.mcmaster.ca。在这种局面下,投机不再仅仅是逐利,还是一种宣示立场、凝聚共识的过程——一次次看似荒唐的炒作背后,是草根对传统体制的不服与嘲讽,是失败者拒绝认输的呐喊。归根结底,meme 币所累积的,正是一种不可被归零的政治资本。价格涨落之间,群众的愤怒、幽默与希望尽显其中;这股力量不因一次挫败而消散,反而在市场的循环中愈发壮大。也正因如此,我们才说“价格即政治”——在迷因币的世界里,价格不只是数字,更是人民政治能量的晴雨表,哪怕归零也终将卷土重来。cdn-brighterworld.humanities.mcmaster.caosl.com
全球新兴现象:伊斯兰金融的入场
当Crypto在西方世界掀起市场治政的狂潮时,另一股独特力量也悄然融入这一场域:伊斯兰金融携其独特的道德秩序,开始在链上寻找存在感。长期以来,伊斯兰金融遵循着一套区别于世俗资本主义的原则:禁止利息(Riba)、反对过度投机(Gharar/Maysir)、强调实际资产支撑和道德投资。当这些原则遇上去中心化的加密技术,会碰撞出怎样的火花?出人意料的是,这两者竟在“以市场行为表达价值”这个层面产生了惊人的共鸣。伊斯兰金融并不拒绝市场机制本身,只是为其附加了道德准则;Crypto则将市场机制推向了政治高位,用价格来表达社群意志。二者看似理念迥异,实则都承认市场行为可以也应当承载社会价值观。这使得越来越多金融与政治分析人士开始关注:当虔诚的宗教伦理遇上狂野的加密市场,会塑造出何种新范式?
事实上,穆斯林世界已经在探索“清真加密”的道路。一些区块链项目致力于确保协议符合伊斯兰教法(Sharia)的要求。例如Haqq区块链发行的伊斯兰币(ISLM),从规则层面内置了宗教慈善义务——每发行新币即自动将10%拨入慈善DAO,用于公益捐赠,以符合天课(Zakat)的教义nasdaq.comnasdaq.com。同时,该链拒绝利息和赌博类应用,2022年还获得了宗教权威的教令(Fatwa)认可其合规性nasdaq.com。再看理念层面,伊斯兰经济学强调货币必须有内在价值、收益应来自真实劳动而非纯利息剥削。这一点与比特币的“工作量证明”精神不谋而合——有人甚至断言法定货币无锚印钞并不清真,而比特币这类需耗费能源生产的资产反而更符合教法初衷cointelegraph.com。由此,越来越多穆斯林投资者开始以道德投资的名义进入Crypto领域,将资金投向符合清真原则的代币和协议。
这种现象带来了微妙的双重合法性:一方面,Crypto世界原本奉行“价格即真理”的世俗逻辑,而伊斯兰金融为其注入了一股道德合法性,使部分加密资产同时获得了宗教与市场的双重背书;另一方面,即便在遵循宗教伦理的项目中,最终决定成败的依然是市场对其价值的认可。道德共识与市场共识在链上交汇,共同塑造出一种混合的新秩序。这一全球新兴现象引发广泛议论:有人将其视为金融民主化的极致表现——不同文化价值都能在市场平台上表达并竞争;也有人警惕这可能掩盖新的风险,因为把宗教情感融入高风险资产,既可能凝聚强大的忠诚度,也可能在泡沫破裂时引发信仰与财富的双重危机。但无论如何,伊斯兰金融的入场使Crypto的政治版图更加丰盈多元。从华尔街交易员到中东教士,不同背景的人们正通过Crypto这个奇特的舞台,对人类价值的表达方式进行前所未有的实验。
升华结语:价格即政治的新直觉
回顾比特币问世以来的这段历程,我们可以清晰地看到一条演进的主线:先有货币革命,后有政治发明。比特币赋予了人类一种真正自主的数字货币,而Crypto在此基础上完成的,则是一项前所未有的政治革新——它让市场价格行为承担起了类似政治选票的功能,开创了一种“价格即政治”的新直觉。在这个直觉下,市场不再只是冷冰冰的交易场所;每一次资本流动、每一轮行情涨落,都被赋予了社会意义和政治涵义。买入即表态,卖出即抗议,流动性的涌入或枯竭胜过千言万语的陈情。Crypto世界中,K线图俨然成为民意曲线,行情图就是政治晴雨表。决策不再由少数权力精英关起门来制定,而是在全球无眠的交易中由无数普通人共同谱写。这样的政治形式也许狂野,也许充满泡沫和噪音,但它不可否认地调动起了广泛的社会参与,让原本疏离政治进程的个体通过持币、交易重新找回了影响力的幻觉或实感。
“价格即政治”并非一句简单的口号,而是Crypto给予世界的全新想象力。它质疑了传统政治的正统性:如果一串代码和一群匿名投资者就能高效决策资源分配,我们为何还需要繁冗的官僚体系?它也拷问着自身的内在隐忧:当财富与权力深度绑定,Crypto政治如何避免堕入金钱统治的老路?或许,正是在这样的矛盾和张力中,人类政治的未来才会不断演化。Crypto所开启的,不仅是技术乌托邦或金融狂欢,更可能是一次对民主形式的深刻拓展和挑战。这里有最狂热的逐利者,也有最理想主义的社群塑梦者;有一夜暴富的神话,也有瞬间破灭的惨痛。而这一切汇聚成的洪流,正冲撞着工业时代以来既定的权力谱系。
当我们再次追问:Crypto究竟是什么? 或许可以这样回答——Crypto是比特币之后,人类完成的一次政治范式的试验性跃迁。在这里,价格行为化身为选票,资本市场演化为广场,代码与共识共同撰写“社会契约”。这是一场仍在进行的文明实验:它可能无声地融入既有秩序,也可能剧烈地重塑未来规则。但无论结局如何,如今我们已经见证:在比特币发明真正的货币之后,Crypto正在发明真正属于21世纪的政治。它以数字时代的语言宣告:在链上,价格即政治,市场即民意,代码即法律。这,或许就是Crypto带给我们的最直观而震撼的本质启示。

2025-03-22 11:22:07Keys and Addresses
อลิซต้องการจ่ายเงินให้กับบ๊อบแต่โหนดของบิตคอยน์ในระบบหลายพันโหนดจะตรวจสอบธุรกรรมของเธอ โดยไม่รู้ว่าอลิซหรือบ๊อบเป็นใคร ละเราต้องการรักษาความเป็นส่วนตัวของพวกเขาไว้เช่นนี้ อลิซจำเป็นต้องสื่อสารว่าบ๊อบควรได้รับบิตคอยน์บางส่วนของเธอโดยไม่เชื่อมโยงแง่มุมใด ๆ ของธุรกรรมนั้นกับตัวตนในโลกจริงของบ๊อบ หรือกับการชำระเงินด้วยบิตคอยน์ครั้งอื่น ๆ ที่บ๊อบได้รับ อลิซใช้ต้องทำให้มั่นใจว่ามีเพียแค่บ๊อบเท่านั้นที่สามารถใช้จ่ายบิตคอยน์ที่เขาได้รับต่อไปได้
ในบิตคอยน์ไวท์เปเปอร์ได้อธิบายถึงแผนการที่เรียบง่ายมากสำหรับการบรรลุเป้าหมายเหล่านั้น ดังที่แสดงในรูปด้านล่างนี้
ตัวของผู้รับอย่างบ๊อบเองจะได้รับบิตคอยน์ไปยัง public key ของเขาที่ถูกลงนามโดยผู้จ่ายอย่างอลิซ โดยบิตคอยน์ที่อลิซนำมาจ่ายนั้นก็ได้รับมาจากที่ใครสักคนส่งมาที่ public key ของเธอ และเธอก็ใช้ private key ของเธอในการลงนามเพื่อสร้างลายเซ็นของเธอและโหนดต่าง ๆ ของบิตคอยน์จะทำการตรวจสอบว่าลายเซ็นของอลิซผูกมัดกับเอาต์พุตของฟังก์ชันแฮชซึ่งตัวมันเองผูกมัดกับ public key ของบ๊อบและรายละเอียดธุรกรรมอื่นๆ
ในบทนี้เราจะพิจารณาpublic key private key Digital signatrue และ hash function จากนั้นใช้ทั้งหมดนี้ร่วมกันเพื่ออธิบาย address ที่ใช้โดยซอฟต์แวร์บิตคอยน์สมัยใหม่
Public Key Cryptography (การเข้ารหัสของ public key)
ระบบเข้ารหัสของ public key ถูกคิดค้นขึ้นในทศวรรษ 1970 มาจากรากฐานทางคณิตศาสตร์สำหรับความปลอดภัยของคอมพิวเตอร์และข้อมูลสมัยใหม่
นับตั้งแต่การคิดค้นระบบเข้ารหัส public key ได้มีการค้นพบฟังก์ชันทางคณิตศาสตร์ที่เหมาะสมหลายอย่าง เช่น การยกกำลังของจำนวนเฉพาะและการคูณของเส้นโค้งวงรี โดยฟังก์ชันทางคณิตศาสตร์เหล่านี้สามารถคำนวณได้ง่ายในทิศทางหนึ่ง แต่เป็นไปไม่ได้ที่จะคำนวณในทิศทางตรงกันข้ามโดยใช้คอมพิวเตอร์และอัลกอริทึมที่มีอยู่ในปัจจุบัน จากฟังก์ชันทางคณิตศาสตร์เหล่านี้ การเข้ารหัสลับช่วยให้สามารถสร้างลายเซ็นดิจิทัลที่ไม่สามารถปลอมแปลงได้และบิตคอยน์ได้ใช้การบวกและการคูณของเส้นโค้งวงรีเป็นพื้นฐานสำหรับการเข้ารหัสลับของมัน
ในบิตคอยน์ เราสามารถใช้ระบบเข้ารหัส public key เพื่อสร้างคู่กุญแจที่ควบคุมการเข้าถึงบิตคอยน์ คู่กุญแจประกอบด้วย private key และ public key ที่ได้มาจาก private key public keyใช้สำหรับรับเงิน และ private key ใช้สำหรับลงนามในธุรกรรมเพื่อใช้จ่ายเงิน
ความสัมพันธ์ทางคณิตศาสตร์ระหว่าง public key และ private key ที่ช่วยให้ private key สามารถใช้สร้างลายเซ็นบนข้อความได้ ลายเซ็นเหล่านี้สามารถตรวจสอบความถูกต้องกับ public key ได้โดยไม่เปิดเผย private key
TIP: ในการใช้งานซอฟแวร์กระเป๋าเงินบิตคอยน์บสงอัน จะทำการเก็บ private key และ public key ถูกเก็บไว้ด้วยกันในรูปแบบคู่กุญแจเพื่อความสะดวก แต่อย่างไรก็ตาม public key สามารถคำนวณได้จาก private key ดังนั้นการเก็บเพียง private key เท่านั้นก็เป็นไปได้เช่นกัน
bitcoin wallet มักจะทำการรวบรวมคู่กุญแต่ละคู่ ซึ่งจะประกอบไปด้วย private key และ public key โดย private key จะเป็นตัวเลขที่ถูกสุ่มเลือกขึ้นมา และเราขะใช้เส้นโค้งวงรี ซึ่งเป็นฟังก์ชันการเข้ารหัสทางเดียว เพื่อสร้าง public key ขึ้นมา
ทำไมจึงใช้การเข้ารหัสแบบอสมมาตร
ทำไมการเข้ารหัสแบบอสมมาตรจึงถูกใช้บิตคอยน์? มันไม่ได้ถูกใช้เพื่อ "เข้ารหัส" (ทำให้เป็นความลับ) ธุรกรรม แต่คุณสมบัติที่มีประโยชน์ของการเข้ารหัสแบบอสมมาตรคือความสามารถในการสร้าง ลายเซ็นดิจิทัล private key สามารถนำไปใช้กับธุรกรรมเพื่อสร้างลายเซ็นเชิงตัวเลข ลายเซ็นนี้สามารถสร้างได้เฉพาะโดยผู้ที่มีความเกี่ยวข้องกับ private key เท่านั้น แต่อย่างไรก็ตาม ทุกคนที่สามารถเข้าถึง public key และธุรกรรมสามารถใช้สิ่งเหล่านี้เพื่อ ตรวจสอบ ลายเซ็นได้ คุณสมบัติที่มีประโยชน์นี้ของการเข้ารหัสแบบอสมมาตรทำให้ทุกคนสามารถตรวจสอบลายเซ็นทุกรายการในทุกธุรกรรมได้ ในขณะที่มั่นใจว่าเฉพาะเจ้าของ private key เท่านั้นที่สามารถสร้างลายเซ็นที่ถูกต้องได้
Private keys
private key เป็นเพียงตัวเลขที่ถูกสุ่มขึ้น และการควบคุม private key ก็เป็นรากฐานสำคัญที่ทำให้เจ้าชองกุญแจดอกนี้สามารถควบคุมบิตคอยน์ทั้งหมดที่มีความเกี่ยวข้องกับ public key ที่คู่กัน private key นั้นใช้ในการสร้างลายเซ็นดิจิทัลที่ใช้ในการเคลื่อนย้ายบิตคอยน์ เราจำเป็นต้องเก็บ private key ให้เป็นความลับตลอดเวลา เพราะการเปิดเผยมันให้กับบุคคลอื่นนั้นก็เปรียบเสมือนกับการนำอำนาจในการควบคุมบิตคอยน์ไปให้แก่เขา นอกจากนี้ private key ยังจำเป็นต้องได้รับการสำรองข้อมูลและป้องกันจากการสูญหายโดยไม่ตั้งใจ เพราะหากเราได้ทำมันสูญหายไป จะไม่สามารถกู้คืนได้ และบิตคอยน์เหล่านั้นจะถูกปกป้องโดยกุญแจที่หายไปนั้นตลอดกาลเช่นกัน
TIP: private key ของบิตคอยน์นั้นเป็นเพียงแค่ตัวเลข คุณสามารถสร้างมันได้โดยใช้เพียงเหรียญ ดินสอ และกระดาษ โดยการโยนเหรียญเพียง 256 ครั้งจะทำให้คุณได้เลขฐานสองที่สามารถใช้เป็น private key ของบิตคอยน์ จากนั้นคุณสามารถใช้มันในการคำนวณหา public key แต่อย่างไรก็ตาม โปรดระมัดระวังเกี่ยวกับการเลือใช้วิธีการสุ่มที่ไม่สมบูรณ์ เพราะนั่นอาจลดความปลอดภัยของ private key และบิตคอยน์ที่มัมปกป้องอยู่อย่างมีนัยสำคัญ
ขั้นตอนแรกและสำคัญที่สุดในการสร้างกุญแจคือการหาแหล่งที่มาของความสุ่มที่ปลอดภัย (ซึ่งเรียกว่า เอนโทรปี) การสร้างกุญแจของบิตคอยน์นั้นเกือบเหมือนกับ "เลือกตัวเลขระหว่าง 1 และ 2^256" ซึ่งวิธีที่แน่นอนที่คุณใช้ในการเลือกตัวเลขนั้นไม่สำคัญตราบใดที่มันไม่สามารถคาดเดาหรือทำซ้ำได้ โดยปกติแล้วซอฟต์แวร์ของบิตคอยน์มักจะใช้ตัวสร้างตัวเลขสุ่มที่มีความปลอดภัยทางการเข้ารหัสเพื่อสร้างเอนโทรปี 256 บิต
สิ่งที่สำคัญในเรื่องนี้คือ private key สามารถเป็นตัวเลขใดๆ ระหว่าง 0 และ n - 1 (รวมทั้งสองค่า) โดยที่ n เป็นค่าคงที่ (n = 1.1578 × 10^77 ซึ่งน้อยกว่า 2^256 เล็กน้อย) ซึ่งกำหนดอยู่ใน elliptic curve ที่ใช้ใน Bitcoin ในการสร้างกุญแจดังกล่าว เราสุ่มเลือกเลขขนาด 256 บิตและตรวจสอบว่ามันน้อยกว่า n ในแง่ของการเขียนโปรแกรม โดยปกติแล้วสิ่งนี้ทำได้โดยการป้อนสตริงของบิตสุ่มที่ใหญ่กว่า ซึ่งรวบรวมจากแหล่งที่มาของความสุ่มที่มีความปลอดภัยทางการเข้ารหัส เข้าไปในอัลกอริทึมแฮช SHA256 ซึ่งจะสร้างค่าขนาด 256 บิตที่สามารถตีความเป็นตัวเลขได้อย่างสะดวก หากผลลัพธ์น้อยกว่า n เราจะได้กุญแจส่วนตัวที่เหมาะสม มิฉะนั้น เราก็เพียงแค่ลองอีกครั้งด้วยตัวเลขสุ่มอื่น
คำเตือน: อย่าเขียนโค้ดของคุณเองเพื่อสร้างตัวเลขสุ่ม หรือใช้ตัวสร้างตัวเลขสุ่ม "แบบง่าย" ที่มีให้ในภาษาโปรแกรมของคุณ ใช้ตัวสร้างตัวเลขสุ่มเทียมที่มีความปลอดภัยทางการเข้ารหัส (CSPRNG) จากแหล่งที่มีเอนโทรปีเพียงพอ ศึกษาเอกสารของไลบรารีตัวสร้างตัวเลขสุ่มที่คุณเลือกเพื่อให้มั่นใจว่ามีความปลอดภัยทางการเข้ารหัส การใช้งาน CSPRNG ที่ถูกต้องมีความสำคัญอย่างยิ่งต่อความปลอดภัยของกุญแจ
ต่อไปนี้คือกุญแจส่วนตัว (k) ที่สร้างขึ้นแบบสุ่มซึ่งแสดงในรูปแบบเลขฐานสิบหก (256 บิตแสดงเป็น 64 หลักเลขฐานสิบหก โดยแต่ละหลักคือ 4 บิต):
1E99423A4ED27608A15A2616A2B0E9E52CED330AC530EDCC32C8FFC6A526AEDD
TIP: จำนวนที่เป็นไปได้ของ private key ทั้งหมดนั้นมีอยู่ 2^256 เป็นตัวเลขที่ใหญ่มากจนยากจะจินตนาการได้ มันมีค่าประมาณ 10^77 (เลข 1 ตามด้วยเลข 0 อีก 77 ตัว) ในระบบเลขฐานสิบ เพื่อให้เข้าใจง่ายขึ้น ลองเปรียบเทียบกับจักรวาลที่เรามองเห็นได้ซึ่งนักวิทยาศาสตร์ประมาณการว่ามีอะตอมทั้งหมดประมาณ 10^80 อะตอม นั่นหมายความว่าช่วงค่าของกุญแจส่วนตัว Bitcoin มีขนาดใกล้เคียงกับจำนวนอะตอมทั้งหมดในจักรวาลที่เรามองเห็นได้
การอธิบายเกี่ยวกับวิทยาการเข้ารหัสแบบเส้นโค้งวงรี (Elliptic Curve Cryptography)
วิทยาการเข้ารหัสแบบเส้นโค้งวงรี (ECC) เป็นประเภทหนึ่งของการเข้ารหัสแบบอสมมาตรหรือ public key ซึ่งอาศัยหลักการของปัญหาลอการิทึมแบบไม่ต่อเนื่อง โดยแสดงออกผ่านการบวกและการคูณบนจุดต่างๆ ของเส้นโค้งวงรี
บิตคอยน์ใช้เส้นโค้งวงรีเฉพาะและชุดค่าคงที่ทางคณิตศาสตร์ ตามที่กำหนดไว้ในมาตรฐานที่เรียกว่า secp256k1 ซึ่งกำหนดโดยสถาบันมาตรฐานและเทคโนโลยีแห่งชาติ (NIST) เส้นโค้ง secp256k1 ถูกกำหนดโดยฟังก์ชันต่อไปนี้ ซึ่งสร้างเส้นโค้งวงรี: y² = (x³ + 7) บนฟิลด์จำกัด (F_p) หรือ y² mod p = (x³ + 7) mod p
โดยที่ mod p (มอดูโลจำนวนเฉพาะ p) แสดงว่าเส้นโค้งนี้อยู่บนฟิลด์จำกัดของอันดับจำนวนเฉพาะ p ซึ่งเขียนได้เป็น F_p โดย p = 2^256 – 2^32 – 2^9 – 2^8 – 2^7 – 2^6 – 2^4 – 1 ซึ่งเป็นจำนวนเฉพาะที่มีค่ามหาศาล
บิตคอยน์ใช้เส้นโค้งวงรีที่ถูกนิยามบนฟิลด์จำกัดของอันดับจำนวนเฉพาะแทนที่จะอยู่บนจำนวนจริง ทำให้มันมีลักษณะเหมือนรูปแบบของจุดที่กระจัดกระจายในสองมิติ ซึ่งทำให้ยากต่อการจินตนาการภาพ อย่างไรก็ตาม คณิตศาสตร์ที่ใช้นั้นเหมือนกับเส้นโค้งวงรีบนจำนวนจริง
ตัวอย่างเช่น การเข้ารหัสลับด้วยเส้นโค้งวงรี: การแสดงภาพเส้นโค้งวงรีบน F(p) โดยที่ p=17 แสดงเส้นโค้งวงรีเดียวกันบนฟิลด์จำกัดของอันดับจำนวนเฉพาะ 17 ที่มีขนาดเล็กกว่ามาก ซึ่งแสดงรูปแบบของจุดบนตาราง
เส้นโค้งวงรี secp256k1 ที่ใช้ในบิตคอยน์สามารถนึกถึงได้ว่าเป็นรูปแบบของจุดที่ซับซ้อนมากกว่าบนตารางที่มีขนาดใหญ่มหาศาลจนยากจะเข้าใจได้
ตัวอย่างเช่น จุด P ที่มีพิกัด (x, y) ต่อไปนี้เป็นจุดที่อยู่บนเส้นโค้ง secp256k1:
P = (55066263022277343669578718895168534326250603453777594175500187360389116729240, 32670510020758816978083085130507043184471273380659243275938904335757337482424)
เราสามารถใช้ Python เพื่อยืนยันว่าจุดนี้อยู่บนเส้นโค้งวงรีได้ตามตัวอย่างนี้: ตัวอย่างที่ 1: การใช้ Python เพื่อยืนยันว่าจุดนี้อยู่บนเส้นโค้งวงรี ``` Python 3.10.6 (main, Nov 14 2022, 16:10:14) [GCC 11.3.0] on linux Type "help", "copyright", "credits" or "license" for more information.p = 115792089237316195423570985008687907853269984665640564039457584007908834671663 x = 55066263022277343669578718895168534326250603453777594175500187360389116729240 y = 32670510020758816978083085130507043184471273380659243275938904335757337482424 (x ** 3 + 7 - y**2) % p 0 ``` ผลลัพธ์เป็น 0 ซึ่งแสดงว่าจุดนี้อยู่บนเส้นโค้งวงรีจริง เพราะเมื่อแทนค่า x และ y ลงในสมการ y² = (x³ + 7) mod p แล้ว ทั้งสองด้านของสมการมีค่าเท่ากัน
ในคณิตศาสตร์ของเส้นโค้งวงรี มีจุดที่เรียกว่า "จุดที่อนันต์" (point at infinity) ซึ่งมีบทบาทคล้ายกับศูนย์ในการบวก บนคอมพิวเตอร์ บางครั้งจุดนี้แทนด้วย x = y = 0 (ซึ่งไม่เป็นไปตามสมการเส้นโค้งวงรี แต่เป็นกรณีพิเศษที่สามารถตรวจสอบได้ง่าย)
มีตัวดำเนินการ + ที่เรียกว่า "การบวก" ซึ่งมีคุณสมบัติคล้ายกับการบวกแบบดั้งเดิมของจำนวนจริงที่เด็กๆ เรียนในโรงเรียน เมื่อมีจุดสองจุด P1 และ P2 บนเส้นโค้งวงรี จะมีจุดที่สาม P3 = P1 + P2 ซึ่งอยู่บนเส้นโค้งวงรีเช่นกัน
ในเชิงเรขาคณิต จุดที่สาม P3 นี้คำนวณได้โดยการลากเส้นระหว่าง P1 และ P2 เส้นนี้จะตัดกับเส้นโค้งวงรีที่จุดเพิ่มเติมอีกหนึ่งจุดพอดี เรียกจุดนี้ว่า P3' = (x, y) จากนั้นให้สะท้อนกับแกน x เพื่อได้ P3 = (x, -y)
มีกรณีพิเศษบางกรณีที่อธิบายความจำเป็นของ "จุดที่อนันต์":
- ถ้า P1 และ P2 เป็นจุดเดียวกัน เส้น "ระหว่าง" P1 และ P2 ควรขยายเป็นเส้นสัมผัสกับเส้นโค้ง ณ จุด P1 นี้ เส้นสัมผัสนี้จะตัดกับเส้นโค้งที่จุดใหม่อีกหนึ่งจุดพอดี คุณสามารถใช้เทคนิคจากแคลคูลัสเพื่อหาความชันของเส้นสัมผัส เทคนิคเหล่านี้ใช้ได้อย่างน่าแปลกใจ แม้ว่าเราจะจำกัดความสนใจไว้ที่จุดบนเส้นโค้งที่มีพิกัดเป็นจำนวนเต็มเท่านั้น!
- ในบางกรณี (เช่น ถ้า P1 และ P2 มีค่า x เดียวกันแต่ค่า y ต่างกัน) เส้นสัมผัสจะตั้งฉากพอดี ซึ่งในกรณีนี้ P3 = "จุดที่อนันต์"
- ถ้า P1 เป็น "จุดที่อนันต์" แล้ว P1 + P2 = P2 ในทำนองเดียวกัน ถ้า P2 เป็นจุดที่อนันต์ แล้ว P1 + P2 = P1 นี่แสดงให้เห็นว่าจุดที่อนันต์มีบทบาทเป็นศูนย์
การบวกนี้มีคุณสมบัติเชิงสมาคม (associative) ซึ่งหมายความว่า (A + B) + C = A + (B + C) นั่นหมายความว่าเราสามารถเขียน A + B + C โดยไม่ต้องมีวงเล็บและไม่มีความกำกวม
เมื่อเรานิยามการบวกแล้ว เราสามารถนิยามการคูณในแบบมาตรฐานที่ต่อยอดจากการบวก สำหรับจุด P บนเส้นโค้งวงรี ถ้า k เป็นจำนวนเต็มบวก แล้ว kP = P + P + P + … + P (k ครั้ง) โปรดทราบว่า k บางครั้งถูกเรียกว่า "เลขชี้กำลัง"
Public Keys
ในระบบคริปโตกราฟีแบบเส้นโค้งวงรี (Elliptic Curve Cryptography) public key ถูกคำนวณจาก private key โดยใช้การคูณเส้นโค้งวงรี ซึ่งเป็นกระบวนการที่ไม่สามารถย้อนกลับได้:
K = k × G
โดยที่:
- k คือ private key
- G คือจุดคงที่ที่เรียกว่า จุดกำเนิด (generator point)
- K คือ public key
การดำเนินการย้อนกลับ ที่เรียกว่า "การหาลอการิทึมแบบไม่ต่อเนื่อง" (finding the discrete logarithm) - คือการคำนวณหา k เมื่อรู้ค่า K - เป็นสิ่งที่ยากมากเทียบเท่ากับการลองค่า k ทุกค่าที่เป็นไปได้ (วิธีการแบบ brute-force)
ความยากของการย้อนกลับนี้คือหลักการความปลอดภัยหลักของระบบ ECC ที่ใช้ในบิตคอยน์ ซึ่งทำให้สามารถเผยแพร่ public key ได้อย่างปลอดภัย โดยที่ไม่ต้องกังวลว่าจะมีใครสามารถคำนวณย้อนกลับเพื่อหา private key ได้
TIP:การคูณเส้นโค้งวงรีเป็นฟังก์ชันประเภทที่นักเข้ารหัสลับเรียกว่า “ trap door function ”:
- เป็นสิ่งที่ทำได้ง่ายในทิศทางหนึ่ง
- แต่เป็นไปไม่ได้ที่จะทำในทิศทางตรงกันข้าม
คนที่มี private key สามารถสร้าง public key ได้อย่างง่ายดาย และสามารถแบ่งปันกับโลกได้โดยรู้ว่าไม่มีใครสามารถย้อนกลับฟังก์ชันและคำนวณ private key จาก public key ได้ กลวิธีทางคณิตศาสตร์นี้กลายเป็นพื้นฐานสำหรับลายเซ็นดิจิทัลที่ปลอมแปลงไม่ได้และมีความปลอดภัย ซึ่งใช้พิสูจน์การควบคุมเงินบิตคอยน์
เริ่มต้นด้วยการใช้ private key ในรูปแบบของตัวเลขสุ่ม เราคูณมันด้วยจุดที่กำหนดไว้ล่วงหน้าบนเส้นโค้งที่เรียกว่า จุดกำเนิด (generator point) เพื่อสร้างจุดอื่นที่อยู่บนเส้นโค้งเดียวกัน ซึ่งคำตอบจะเป็น public key ที่สอดคล้องกัน จุดกำเนิดถูกกำหนดไว้เป็นส่วนหนึ่งของมาตรฐาน secp256k1 และเป็นค่าเดียวกันสำหรับกุญแจทั้งหมดในระบบบิตคอยน์
เนื่องจากจุดกำเนิด G เป็นค่าเดียวกันสำหรับผู้ใช้บิตคอยน์ทุกคน private key (k) ที่คูณกับ G จะได้ public key (K) เดียวกันเสมอ ความสัมพันธ์ระหว่าง k และ K เป็นแบบตายตัวแต่สามารถคำนวณได้ในทิศทางเดียวเท่านั้น คือจาก k ไปยัง K นี่คือเหตุผลที่ public key ของบิตคอยน์ (K) สามารถแบ่งปันกับทุกคนได้โดยไม่เปิดเผย private key (k) ของผู้ใช้
TIP: private key สามารถแปลงเป็น public key ได้ แต่ public key ไม่สามารถแปลงกลับเป็น private key ได้ เพราะคณิตศาสตร์ที่ใช้ทำงานได้เพียงทิศทางเดียวเท่านั้น
เมื่อนำการคูณเส้นโค้งวงรีมาใช้งาน เราจะนำ private key (k) ที่สร้างขึ้นก่อนหน้านี้มาคูณกับจุดกำเนิด G เพื่อหา public key (K):
K = 1E99423A4ED27608A15A2616A2B0E9E52CED330AC530EDCC32C8FFC6A526AEDD × G
public key (K) จะถูกกำหนดเป็นจุด K = (x, y) โดยที่:x = F028892BAD7ED57D2FB57BF33081D5CFCF6F9ED3D3D7F159C2E2FFF579DC341A y = 07CF33DA18BD734C600B96A72BBC4749D5141C90EC8AC328AE52DDFE2E505BDB
เพื่อจะให้เห็นภาพของการคูณจุดด้วยจำนวนเต็มมากขึ้น เราจะใช้เส้นโค้งวงรีที่ง่ายกว่าบนจำนวนจริง (โดยหลักการทางคณิตศาสตร์ยังคงเหมือนกัน) เป้าหมายของเราคือการหาผลคูณ kG ของจุดกำเนิด G ซึ่งเทียบเท่ากับการบวก G เข้ากับตัวเอง k ครั้งติดต่อกันในเส้นโค้งวงรี การบวกจุดเข้ากับตัวเองเทียบเท่ากับการลากเส้นสัมผัสที่จุดนั้นและหาว่าเส้นนั้นตัดกับเส้นโค้งอีกครั้งที่จุดใด จากนั้นจึงสะท้อนจุดนั้นบนแกน x
การเข้ารหัสลับด้วยเส้นโค้งวงรี: การแสดงภาพการคูณจุด G ด้วยจำนวนเต็ม k บนเส้นโค้งวงรี แสดงกระบวนการในการหา G, 2G, 4G เป็นการดำเนินการทางเรขาคณิตบนเส้นโค้งได้ดังนี้
TIP: ในซอฟแวร์ของบิตคอยน์ส่วนใหญ่ใช้ไลบรารีเข้ารหัสลับ libsecp256k1 เพื่อทำการคำนวณทางคณิตศาสตร์เส้นโค้งวงรี
Output and Input Scripts
แม้ว่าภาพประกอบจาก Bitcoin whitepaper ที่แสดงเรื่อง "Transaction chain" จะแสดงให้เห็นว่ามีการใช้ public key และ digital signature โดยตรง แต่ในความเป็นจริงบิตคอยน์เวอร์ชันแรกนั้นมีการส่งการชำระเงินไปยังฟิลด์ที่เรียกว่า output script และมีการใช้จ่ายบิตคอยน์เหล่านั้นโดยได้รับอนุญาตจากฟิลด์ที่เรียกว่า input script ฟิลด์เหล่านี้อนุญาตให้มีการดำเนินการเพิ่มเติมนอกเหนือจาก (หรือแทนที่) การตรวจสอบว่าลายเซ็นสอดคล้องกับ public key หรือไม่ ตัวอย่างเช่น output script สามารถมี public key สองดอกและต้องการลายเซ็นสองลายเซ็นที่สอดคล้องกันในฟิลด์ input script ที่ใช้จ่าย
ในภายหลัง ในหัวข้อ [tx_script] เราจะได้เรียนรู้เกี่ยวกับสคริปต์อย่างละเอียด สำหรับตอนนี้ สิ่งที่เราต้องเข้าใจคือ บิตคอยน์จะถูกรับเข้า output script ที่ทำหน้าที่เหมือน public key และการใช้จ่ายบิตคอยน์จะได้รับอนุญาตโดย input script ที่ทำหน้าที่เหมือนลายเซ็น
IP Addresses: The Original Address for Bitcoin (P2PK)
เราได้เห็นแล้วว่าอลิซสามารถจ่ายเงินให้บ็อบโดยการมอบบิตคอยน์บางส่วนของเธอให้กับกุญแจสาธารณะของบ็อบ แต่อลิซจะได้กุญแจสาธารณะของบ็อบมาได้อย่างไร? บ็อบอาจจะให้สำเนากุญแจแก่เธอ แต่ลองดูกุญแจสาธารณะที่เราใช้งานในตัวอย่างที่ผ่านมาอีกครั้ง:
x = F028892BAD7ED57D2FB57BF33081D5CFCF6F9ED3D3D7F159C2E2FFF579DC341A y = 07CF33DA18BD734C600B96A72BBC4749D5141C90EC8AC328AE52DDFE2E505BDB
TIP จากหลาม: :สังเกตได้ว่า public key มีความยาวมาก ลองจินตนาการว่าบ็อบพยายามอ่านกุญแจนี้ให้อลิซฟังทางโทรศัพท์ คงจะยากมากที่จะอ่านและบันทึกโดยไม่มีข้อผิดพลาด
แทนที่จะป้อนกุญแจสาธารณะโดยตรง เวอร์ชันแรกของซอฟต์แวร์บิตคอยน์อนุญาตให้ผู้จ่ายเงินป้อนที่อยู่ IP ของผู้รับได้ ตามที่แสดงในหน้าจอการส่งเงินรุ่นแรกของบิตคอยน์ผ่าน The Internet Archive
คุณสมบัตินี้ถูกลบออกในภายหลัง เนื่องจากมีปัญหามากมายในการใช้ที่อยู่ IP แต่คำอธิบายสั้นๆ จะช่วยให้เราเข้าใจได้ดีขึ้นว่าทำไมคุณสมบัติบางอย่างอาจถูกเพิ่มเข้าไปในโปรโตคอลบิตคอยน์
เมื่ออลิซป้อนที่อยู่ IP ของบ็อบในบิตคอยน์เวอร์ชัน 0.1 Full node ของเธอจะทำการเชื่อมต่อกับ full node ของเขาและได้รับ public key ใหม่จากกระเป๋าสตางค์ของบ็อบที่โหนดของเขาไม่เคยให้กับใครมาก่อน การที่เป็น public key ใหม่นี้มีความสำคัญเพื่อให้แน่ใจว่าธุรกรรมต่าง ๆ ที่จ่ายให้บ็อบจะไม่สามารถถูกเชื่อมโยงเข้าด้วยกันโดยคนที่กำลังดูบล็อกเชนและสังเกตเห็นว่าธุรกรรมทั้งหมดจ่ายไปยัง public key เดียวกัน
เมื่อใช้ public key จากโหนดของอลิซซึ่งได้รับมาจากโหนดของบ็อบ กระเป๋าสตางค์ของอลิซจะสร้างเอาต์พุตธุรกรรมที่จ่ายให้กับสคริปต์เอาต์พุตดังนี้
<Bob's public key> OP_CHECKSIG
ต่อมาบ็อบจะสามารถใช้จ่ายเอาต์พุตนั้นด้วยสคริปต์อินพุตที่ประกอบด้วยลายเซ็นของเขาเท่านั้น:<Bob's signature>
เพื่อให้เข้าใจว่าสคริปต์อินพุตและเอาต์พุตกำลังทำอะไร คุณสามารถรวมพวกมันเข้าด้วยกัน (สคริปต์อินพุตก่อน) แล้วสังเกตว่าข้อมูลแต่ละชิ้น (แสดงในเครื่องหมาย < >) จะถูกวางไว้ที่ด้านบนสุดของรายการที่เรียกว่าสแตก (stack) เมื่อพบรหัสคำสั่ง (opcode) มันจะใช้รายการจากสแตก โดยเริ่มจากรายการบนสุด มาดูว่ามันทำงานอย่างไรโดยเริ่มจากสคริปต์ที่รวมกัน:<Bob's signature> <Bob's public key> OP_CHECKSIG
สำหรับสคริปต์นี้ ลายเซ็นของบ็อบจะถูกนำไปไว้บนสแตก จากนั้น public key ของบ็อบจะถูกวางไว้ด้านบนของลายเซ็น และบนสุดจะเป็นคำสั่ง OP_CHECKSIG ที่จะใช้องค์ประกอบสองอย่าง เริ่มจาก public key ตามด้วยลายเซ็น โดยลบพวกมันออกจากสแตก มันจะตรวจสอบว่าลายเซ็นตรงกับ public key และยืนยันฟิลด์ต่าง ๆ ในธุรกรรม ถ้าลายเซ็นถูกต้อง OP_CHECKSIG จะแทนที่ตัวเองบนสแตกด้วยค่า 1 ถ้าลายเซ็นไม่ถูกต้อง มันจะแทนที่ตัวเองด้วย 0 ถ้ามีรายการที่ไม่ใช่ศูนย์อยู่บนสุดของสแตกเมื่อสิ้นสุดการประเมิน สคริปต์ก็จะผ่าน ถ้าสคริปต์ทั้งหมดในธุรกรรมผ่าน และรายละเอียดอื่น ๆ ทั้งหมดเกี่ยวกับธุรกรรมนั้นต้องถูกต้องจึงจะถือว่าธุรกรรมนั้นถูกต้อง
โดยสรุป สคริปต์ข้างต้นใช้ public key และลายเซ็นเดียวกันกับที่อธิบายใน whitepaper แต่เพิ่มความซับซ้อนของฟิลด์สคริปต์สองฟิลด์และรหัสคำสั่งหนึ่งตัว ซึ่งเราจะเริ่มเห็นประโยชน์เมื่อเรามองที่ส่วนต่อไป
TIP:จากหลาม agian: เอาต์พุตประเภทนี้เป็นที่รู้จักในปัจจุบันว่า P2PK ซึ่งมันไม่เคยถูกใช้อย่างแพร่หลายสำหรับการชำระเงิน และไม่มีโปรแกรมที่ใช้กันอย่างแพร่หลายที่รองรับการชำระเงินผ่านที่อยู่ IP เป็นเวลาเกือบทศวรรษแล้ว
Legacy addresses for P2PKH
แน่นอนว่าการป้อนที่อยู่ IP ของคนที่คุณต้องการจ่ายเงินให้นั้นมีข้อดีหลายประการ แต่ก็มีข้อเสียหลายประการเช่นกัน หนึ่งในข้อเสียที่สำคัญคือผู้รับจำเป็นต้องให้กระเป๋าสตางค์ของพวกเขาออนไลน์ที่ที่อยู่ IP ของพวกเขา และต้องสามารถเข้าถึงได้จากโลกภายนอก
ซึ่งสำหรับคนจำนวนมากนั่นไม่ใช่ตัวเลือกที่เป็นไปได้เพราะหากพวกเขา:
- ปิดคอมพิวเตอร์ในเวลากลางคืน
- แล็ปท็อปของพวกเขาเข้าสู่โหมดสลีป
- อยู่หลังไฟร์วอลล์
- หรือกำลังใช้การแปลงที่อยู่เครือข่าย (NAT)
ปัญหานี้นำเรากลับมาสู่ความท้าทายเดิมที่ผู้รับเงินอย่างบ็อบต้องให้ public key ที่มีความยาวมากแก่ผู้จ่ายเงินอย่างอลิซ public key ของบิตคอยน์ที่สั้นที่สุดที่นักพัฒนาบิตคอยน์รุ่นแรกรู้จักมีขนาด 65 ไบต์ เทียบเท่ากับ 130 ตัวอักษรเมื่อเขียนในรูปแบบเลขฐานสิบหก (เฮกซาเดซิมอล) แต่อย่างไรก็ตาม บิตคอยน์มีโครงสร้างข้อมูลหลายอย่างที่มีขนาดใหญ่กว่า 65 ไบต์มาก ซึ่งจำเป็นต้องถูกอ้างอิงอย่างปลอดภัยในส่วนอื่น ๆ ของบิตคอยน์โดยใช้ข้อมูลขนาดเล็กที่สุดเท่าที่จะปลอดภัยได้
โดยบิตคอยน์แก้ปัญหานี้ด้วย ฟังก์ชันแฮช (hash function) ซึ่งเป็นฟังก์ชันที่รับข้อมูลที่อาจมีขนาดใหญ่ นำมาแฮช และให้ผลลัพธ์เป็นข้อมูลขนาดคงที่ ฟังก์ชันแฮชจะผลิตผลลัพธ์เดียวกันเสมอเมื่อได้รับข้อมูลนำเข้าแบบเดียวกัน และฟังก์ชันที่ปลอดภัยจะทำให้เป็นไปไม่ได้ในทางปฏิบัติสำหรับผู้ที่ต้องการเลือกข้อมูลนำเข้าอื่นที่ให้ผลลัพธ์เหมือนกันได้ นั่นทำให้ผลลัพธ์เป็น คำมั่นสัญญา (commitment) ต่อข้อมูลนำเข้า เป็นสัญญาว่าในทางปฏิบัติ มีเพียงข้อมูลนำเข้า x เท่านั้นที่จะให้ผลลัพธ์ X
สมมติว่าผมต้องการถามคำถามคุณและให้คำตอบของผมในรูปแบบที่คุณไม่สามารถอ่านได้ทันที สมมติว่าคำถามคือ "ในปีไหนที่ซาโตชิ นาคาโมโตะเริ่มทำงานบนบิทคอยน์?" ผมจะให้การยืนยันคำตอบของผมในรูปแบบของผลลัพธ์จากฟังก์ชันแฮช SHA256 ซึ่งเป็นฟังก์ชันที่ใช้บ่อยที่สุดในบิทคอยน์:
94d7a772612c8f2f2ec609d41f5bd3d04a5aa1dfe3582f04af517d396a302e4e
ต่อมา หลังจากคุณบอกคำตอบที่คุณเดาสำหรับคำถามนั้น ผมสามารถเปิดเผยคำตอบของผมและพิสูจน์ให้คุณเห็นว่าคำตอบของผม เมื่อใช้เป็นข้อมูลสำหรับฟังก์ชันแฮช จะให้ผลลัพธ์เดียวกันกับที่ผมให้คุณก่อนหน้านี้$ echo "2007. He said about a year and a half before Oct 2008" | sha256sum 94d7a772612c8f2f2ec609d41f5bd3d04a5aa1dfe3582f04af517d396a302e4e
ทีนี้ให้สมมติว่าเราถามบ็อบว่า " public key ของคุณคืออะไร?" บ็อบสามารถใช้ฟังก์ชันแฮชเพื่อให้การยืนยันที่ปลอดภัยทางการเข้ารหัสต่อ public key ของเขา หากเขาเปิดเผยกุญแจในภายหลัง และเราตรวจสอบว่ามันให้ผลการยืนยันเดียวกันกับที่เขาให้เราก่อนหน้านี้ เราสามารถมั่นใจได้ว่ามันเป็นกุญแจเดียวกันที่ใช้สร้างการยืนยันก่อนหน้านี้ฟังก์ชันแฮช SHA256 ถือว่าปลอดภัยมากและให้ผลลัพธ์ 256 บิต (32 ไบต์) น้อยกว่าครึ่งหนึ่งของขนาด public key ของบิทคอยน์ดั้งเดิม แต่อย่างไรก็ตาม มีฟังก์ชันแฮชอื่นๆ ที่ปลอดภัยน้อยกว่าเล็กน้อยที่ให้ผลลัพธ์ขนาดเล็กกว่า เช่น ฟังก์ชันแฮช RIPEMD-160 ซึ่งให้ผลลัพธ์ 160 บิต (20 ไบต์) ด้วยเหตุผลที่ซาโตชิ นาคาโมโตะไม่เคยระบุ เวอร์ชันดั้งเดิมของบิทคอยน์สร้างการยืนยันต่อ public key โดยการแฮชกุญแจด้วย SHA256 ก่อน แล้วแฮชผลลัพธ์นั้นด้วย RIPEMD-160 ซึ่งให้การยืนยันขนาด 20 ไบต์ต่อ public key
เราสามารถดูสิ่งนี้ตามอัลกอริทึม เริ่มจากกุญแจสาธารณะ K เราคำนวณแฮช SHA256 และคำนวณแฮช RIPEMD-160 ของผลลัพธ์ ซึ่งให้ตัวเลข 160 บิต (20 ไบต์): A = RIPEMD160(SHA256(K))
ทีนี้เราคงเข้าใจวิธีสร้างการยืนยันต่อ public key แล้ว ต่อไปเราจะมาดูวิธีการใช้งานโดยพิจารณาสคริปต์เอาต์พุตต่อไปนี้:
OP_DUP OP_HASH160 <Bob's commitment> OP_EQUAL OP_CHECKSIG
และสคริปต์อินพุตต่อไปนี้:<Bob's signature> <Bob's public key>
และเมื่อเรารวมมันเข้าด้วยกันเราจะได้ผลลัพธ์ดังนี้:<Bob's signature> <Bob's public key> OP_DUP OP_HASH160 <Bob's commitment> OP_EQUAL OP_CHECKSIG
เหมือนที่เราทำใน IP Addresses: The Original Address for Bitcoin (P2PK) เราเริ่มวางรายการลงในสแต็ก ลายเซ็นของบ็อบถูกวางก่อน จากนั้น public key ของเขาถูกวางไว้ด้านบน จากนั้นดำเนินการ OP_DUP เพื่อทำสำเนารายการบนสุด ดังนั้นรายการบนสุดและรายการที่สองจากบนในสแต็กตอนนี้เป็น public key ของบ็อบทั้งคู่ การดำเนินการ OP_HASH160 ใช้ (ลบ) public key บนสุดและแทนที่ด้วยผลลัพธ์ของการแฮชด้วย RIPEMD160(SHA256(K)) ดังนั้นตอนนี้บนสุดของสแต็กคือแฮชของ public key ของบ็อบ ต่อไป commitment ถูกเพิ่มไว้บนสุดของสแต็ก การดำเนินการ OP_EQUALVERIFY ใช้รายการสองรายการบนสุดและตรวจสอบว่าพวกมันเท่ากัน ซึ่งควรเป็นเช่นนั้นหาก public key ที่บ็อบให้ในสคริปต์อินพุตเป็น public key เดียวกันกับที่ใช้สร้างการยืนยันในสคริปต์เอาต์พุตที่อลิซจ่าย หาก OP_EQUALVERIFY ล้มเหลว ทั้งสคริปต์จะล้มเหลว สุดท้าย เราเหลือสแต็กที่มีเพียงลายเซ็นของบ็อบและ public key ของเขา รหัสปฏิบัติการ OP_CHECKSIG ตรวจสอบว่าพวกมันสอดคล้องกัน
TIP: จากหลาม ถ้าอ่านตรงนี้และงง ๆ ผมไปทำรูปมาให้ดูง่ายขึ้นครับ
แม้กระบวนการของการ pay-to-publickey-hash(P2PKH) อาจดูซับซ้อน แต่มันทำให้การที่อลิซจ่ายเงินให้บ็อบมีเพียงการยืนยันเพียง 20 ไบต์ต่อ public key ของเขาแทนที่จะเป็นตัวกุญแจเอง ซึ่งจะมีขนาด 65 ไบต์ในเวอร์ชันดั้งเดิมของบิทคอยน์ นั่นเป็นข้อมูลที่น้อยกว่ามากที่บ็อบต้องสื่อสารกับอลิซ
แต่อย่างไรก็ตาม เรายังไม่ได้พูดถึงวิธีที่บ็อบรับ 20 ไบต์เหล่านั้นจากกระเป๋าเงินบิทคอยน์ของเขาไปยังกระเป๋าเงินของอลิซ มีการเข้ารหัสค่าไบต์ที่ใช้กันอย่างแพร่หลาย เช่น เลขฐานสิบหก แต่ข้อผิดพลาดใด ๆ ในการคัดลอกการยืนยันจะทำให้บิทคอยน์ถูกส่งไปยังเอาต์พุตที่ไม่สามารถใช้จ่ายได้ ทำให้พวกมันสูญหายไปตลอดกาล โดยในส่วนถัดไป เราจะดูที่การเข้ารหัสแบบกะทัดรัดและการตรวจสอบความถูกต้อง
Base58check Encoding
ระบบคอมพิวเตอร์มีวิธีเขียนตัวเลขยาวๆ ให้สั้นลงโดยใช้ทั้งตัวเลขและตัวอักษรผสมกัน เพื่อใช้พื้นที่น้อยลงอย่างเช่น
- ระบบเลขฐานสิบ (ปกติที่เราใช้) - ใช้เลข 0-9 เท่านั้น
- ระบบเลขฐานสิบหก - ใช้เลข 0-9 และตัวอักษร A-F ตัวอย่าง: เลข 255 ในระบบปกติ เขียนเป็น FF ในระบบเลขฐานสิบหก (สั้นกว่า)
- ระบบเลขฐานหกสิบสี่ (Base64) - ใช้สัญลักษณ์ถึง 64 ตัว: ตัวอักษรเล็ก (a-z) 26 ตัว, ตัวอักษรใหญ่ (A-Z) 26 ตัว, ตัวเลข (0-9) 10 ตัว, สัญลักษณ์พิเศษอีก 2 ตัว ("+" และ "/")
โดยระบบ Base64 นี้ช่วยให้เราส่งไฟล์คอมพิวเตอร์ผ่านข้อความธรรมดาได้ เช่น การส่งรูปภาพผ่านอีเมล โดยใช้พื้นที่น้อยกว่าการเขียนเป็นเลขฐานสิบแบบปกติมาก
การเข้ารหัสแบบ Base58 คล้ายกับ Base64 โดยใช้ตัวอักษรพิมพ์ใหญ่ พิมพ์เล็ก และตัวเลข แต่ได้ตัดตัวอักษรบางตัวที่มักถูกเข้าใจผิดว่าเป็นตัวอื่นและอาจดูเหมือนกันเมื่อแสดงในฟอนต์บางประเภทออกไป
Base58 คือ Base64 ที่ตัดตัวอักษรต่อไปนี้ออก:
- เลข 0 (ศูนย์)
- ตัวอักษร O (ตัว O พิมพ์ใหญ่)
- ตัวอักษร l (ตัว L พิมพ์เล็ก)
- ตัวอักษร I (ตัว I พิมพ์ใหญ่)
- และสัญลักษณ์ "+" และ "/"
หรือพูดให้ง่ายขึ้น Base58 คือกลุ่มตัวอักษรพิมพ์เล็ก พิมพ์ใหญ่ และตัวเลข แต่ไม่มีตัวอักษรทั้งสี่ตัว (0, O, l, I) ที่กล่าวถึงข้างต้น ตัวอักษรทั้งหมดที่ใช้ใน Base58 จะแสดงให้เห็นในตัวอักษร Base58 ของบิทคอยน์
Example 2. Bitcoin’s base58 alphabet
123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz
การเพิ่มความปลอดภัยพิเศษเพื่อป้องกันการพิมพ์ผิดหรือข้อผิดพลาดในการคัดลอก base58check ได้รวม รหัสตรวจสอบ (checksum) ที่เข้ารหัสในตัวอักษร base58 เข้าไปด้วย รหัสตรวจสอบนี้คือข้อมูลเพิ่มเติมอีก 4 ไบต์ที่เพิ่มเข้าไปที่ท้ายของข้อมูลที่กำลังถูกเข้ารหัสรหัสตรวจสอบนี้ได้มาจากการแฮชข้อมูลที่ถูกเข้ารหัส และจึงสามารถใช้เพื่อตรวจจับข้อผิดพลาดจากการคัดลอกและการพิมพ์ได้ เมื่อโปรแกรมได้รับรหัส base58check ซอฟต์แวร์ถอดรหัสจะคำนวณรหัสตรวจสอบของข้อมูลและเปรียบเทียบกับรหัสตรวจสอบที่รวมอยู่ในรหัสนั้น
หากทั้งสองไม่ตรงกัน แสดงว่ามีข้อผิดพลาดเกิดขึ้น และข้อมูล base58check นั้นไม่ถูกต้อง กระบวนการนี้ช่วยป้องกันไม่ให้ address บิทคอยน์ที่พิมพ์ผิดถูกยอมรับโดยซอฟต์แวร์กระเป๋าเงินว่าเป็น address ที่ถูกต้อง ซึ่งเป็นข้อผิดพลาดที่อาจส่งผลให้สูญเสียเงินได้
การแปลงข้อมูล (ตัวเลข) เป็นรูปแบบ base58check มีขั้นตอนดังนี้:
- เราเริ่มโดยการเพิ่ม prefix เข้าไปในข้อมูล เรียกว่า "version byte" ซึ่งช่วยให้ระบุประเภทของข้อมูลที่ถูกเข้ารหัสได้ง่าย ตัวอย่างเช่น: prefix ศูนย์ (0x00 ในระบบเลขฐานสิบหก) แสดงว่าข้อมูลควรถูกใช้เป็นการยืนยัน (hash) ในสคริปต์เอาต์พุต legacy P2PKH
- จากนั้น เราคำนวณ "double-SHA" checksum ซึ่งหมายถึงการใช้อัลกอริทึมแฮช SHA256 สองครั้งกับผลลัพธ์ก่อนหน้า (prefix ต่อกับข้อมูล):
checksum = SHA256(SHA256(prefix||data))
- จากแฮช 32 ไบต์ที่ได้ (การแฮชซ้อนแฮช) เราเลือกเฉพาะ 4 ไบต์แรก ไบต์ทั้งสี่นี้ทำหน้าที่เป็นรหัสตรวจสอบข้อผิดพลาดหรือ checksum
- นำ checksum นี้ไปต่อที่ท้ายข้อมูล
การเข้ารหัสแบบ base58check คือรูปแบบการเข้ารหัสที่ใช้ base58 พร้อมกับการระบุเวอร์ชันและการตรวจสอบความถูกต้อง เพื่อการเข้ารหัสข้อมูลบิทคอยน์ โดยคุณสามารถดูภาพประกอบด้านล่างเพื่อความเข้าใจเพิ่มเติม
ในบิตคอยน์นั้น นอกจากจะใช้ base58check ในการยืนยัน public key แล้ว ก็ยังมีการใช้ในข้อมูลอื่น ๆ ด้วย เพื่อทำให้ข้อมูลนั้นกะทัดรัด อ่านง่าย และตรวจจับข้อผิดพลาดได้ง่ายด้วยรหัสนำหน้า (version prefix) ในการเข้ารหัสแบบ base58check ถูกใช้เพื่อสร้างรูปแบบที่แยกแยะได้ง่าย ซึ่งเมื่อเข้ารหัสด้วย base58 โดยจะมีตัวอักษรเฉพาะที่จุดเริ่มต้นของข้อมูลที่เข้ารหัส base58check ตัวอักษรเหล่านี้ช่วยให้เราระบุประเภทของข้อมูลที่ถูกเข้ารหัสและวิธีการใช้งานได้ง่าย นี่คือสิ่งที่แยกความแตกต่าง ตัวอย่างเช่น ระหว่าง address บิทคอยน์ที่เข้ารหัส base58check ซึ่งขึ้นต้นด้วยเลข 1 กับรูปแบบการนำเข้า private key (WIF - Wallet Import Format) ที่เข้ารหัส base58check ซึ่งขึ้นต้นด้วยเลข 5 ตัวอย่างของ version prefix สามารถดูได้ตามตารางด้านล่างนี้
ภาพต่อไปนี้จะทำให้คุณเห็นภาพของกระบวนการแปลง public key ให้เป็น bitcoin address
Compressed Public Keys
ในยุคแรก ๆ ของบิตคอยน์นั้น มีเพียงการสร้าง public key แบบ 65 Bytes เท่านั้น แต่ในเวลาต่อมา เหล่านักพัฒนาในยุคหลังได้พบวิธีการสร้าง public key แบบใหม่ที่มีเพียง 33 Bytes และสามารถทำงานร่วมกันกับโหนดทั้งหมดในขณะนั้นได้ จีงไม่จะเป็นต้องเปลี่ยนแปลงกฎหรือโครงสร้างภายในโปรโตคอลของบิตคอยน์ โดย poublic key แบบใหม่ที่มีขนาด 33 Bytes นี้เรียกว่า compressed public key (public key ที่ถูกบีบอัด) และมีการเรียก public key ที่มีขนาด 65 Bytes ว่า uncompressed public key (public key ที่ไม่ถูกบีบอัด) ซึ่งประโยชน์ของ public key ที่เล็กลงนั้น นอกจากจะช่วยให้การส่ง public key ให้ผู้อื่นทำได้ง่ายขึ้นแล้ว ยังช่วยให้ธุรกรรมมีขนาดเล็กลง และช่วยให้สามารถทำการชำระเงินได้มากขึ้นในบล็อกเดียวกัน
อย่างที่เราได้เรียนรู้จากเนื้อหาในส่วนของ public key เราได้ทราบว่า public key คือจุด (x, y) บนเส้นโค้งวงรี เนื่องจากเส้นโค้งแสดงฟังก์ชันทางคณิตศาสตร์ จุดบนเส้นโค้งจึงเป็นคำตอบของสมการ ดังนั้นหากเรารู้พิกัด x เราก็สามารถคำนวณพิกัด y ได้โดยแก้สมการ y² mod p = (x³ + 7) mod p นั่นหมายความว่าเราสามารถเก็บเพียงพิกัด x ของ public key โดยละพิกัด y ไว้ ซึ่งช่วยลดขนาดของกุญแจและพื้นที่ที่ต้องใช้เก็บข้อมูลลง 256 บิต การลดขนาดลงเกือบ 50% ในทุกธุรกรรมรวมกันแล้วช่วยประหยัดข้อมูลได้มากมายในระยะยาว!
นี่คือ public key ที่ได้ยกเป็นตัวอย่างไว้ก่อนหน้า
x = F028892BAD7ED57D2FB57BF33081D5CFCF6F9ED3D3D7F159C2E2FFF579DC341A y = 07CF33DA18BD734C600B96A72BBC4749D5141C90EC8AC328AE52DDFE2E505BDB
และนี่คือ public key ที่มีตัวนำหน้า 04 ตามด้วยพิกัด x และ y ในรูปแบบ 04 x y:
K = 04F028892BAD7ED57D2FB57BF33081D5CFCF6F9ED3D3D7F159C2E2FFF579DC341A07CF33DA18BD734C600B96A72BBC4749D5141C90EC8AC328AE52DDFE2E505BDB
uncompressed public key นั้นจะมีตัวนำหน้าเป็น 04 แต่ compressed public key จะมีตัวนำหน้าเป็น 02 หรือ 03 โดยเหตุผลนั้นมาจากสมการ y² mod p = (x³ + 7) mod p เนื่องจากด้านซ้ายของสมการคือ y² คำตอบสำหรับ y จึงเป็นรากที่สอง ซึ่งอาจมีค่าเป็นบวกหรือลบก็ได้ หากมองเชิงภาพ นี่หมายความว่าพิกัด y ที่ได้อาจอยู่เหนือหรือใต้แกน x เราต้องไม่ลืมว่าเส้นโค้งมีความสมมาตร ซึ่งหมายความว่ามันจะสะท้อนเหมือนกระจกโดยแกน x ดังนั้น แม้เราจะละพิกัด y ได้ แต่เราต้องเก็บ เครื่องหมาย ของ y (บวกหรือลบ) หรืออีกนัยหนึ่งคือเราต้องจำว่ามันอยู่เหนือหรือใต้แกน x เพราะแต่ละตำแหน่งแทนจุดที่แตกต่างกันและเป็น public key ที่แตกต่างกัน
เมื่อคำนวณเส้นโค้งวงรีในระบบเลขฐานสองบนสนามจำกัดของเลขจำนวนเฉพาะ p พิกัด y จะเป็นเลขคู่หรือเลขคี่ ซึ่งสอดคล้องกับเครื่องหมายบวก/ลบตามที่อธิบายก่อนหน้านี้ ดังนั้น เพื่อแยกความแตกต่างระหว่างค่าที่เป็นไปได้สองค่าของ y เราจึงเก็บ compressed public key ด้วยตัวนำหน้า 02 ถ้า y เป็นเลขคู่ และ 03 ถ้า y เป็นเลขคี่ ซึ่งช่วยให้ซอฟต์แวร์สามารถอนุมานพิกัด y จากพิกัด x และคลายการบีบอัดของ public key ไปยังพิกัดเต็มของจุดได้อย่างถูกต้อง ดังภาพประกอบต่อไปนี้
นี่คือ public key เดียวกันกับที่ยกตัวอย่างไว้ข้างต้นซึ่งแสดงให้เห็นในรูป compressed public key ที่เก็บใน 264 บิต (66 ตัวอักษรเลขฐานสิบหก) โดยมีตัวนำหน้า 03 ซึ่งบ่งชี้ว่าพิกัด y เป็นเลขคี่:
K = 03F028892BAD7ED57D2FB57BF33081D5CFCF6F9ED3D3D7F159C2E2FFF579DC341A
compressed public key สอดคล้องกับ private key เดียวกันกับ uncompressed public key หมายความว่ามันถูกสร้างจาก private key เดียวกัน แต่อย่างไรก็ตาม มันก็มีส่วนที่แตกต่างจาก uncompressed public key นั้นคือ หากเราแปลง compressed public key เป็น commitment โดยใช้ฟังก์ชัน HASH160 (RIPEMD160(SHA256(K))) มันจะสร้าง commitment ที่แตกต่างจาก uncompressed public key และจะนำไปสู่ bitcoin address ที่แตกต่างกันในที่สุด สิ่งนี้อาจทำให้สับสนเพราะหมายความว่า private key เดียวสามารถสร้าง public key ในสองรูปแบบที่แตกต่างกัน (แบบบีบอัดและแบบไม่บีบอัด) ซึ่งสร้าง bitcoin address ที่แตกต่างกันcompressed public key เป็นค่าเริ่มต้นในซอฟต์แวร์บิตคอยน์เกือบทั้งหมดในปัจจุบัน และถูกกำหนดให้ใช้กับคุณสมบัติใหม่บางอย่างที่เพิ่มในการอัปเกรดโปรโตคอลในภายหลัง
อย่างไรก็ตาม ซอฟต์แวร์บางตัวยังคงต้องรองรับ uncompressed public key เช่น แอปพลิเคชันกระเป๋าเงินที่นำเข้า private key จากกระเป๋าเงินเก่า เมื่อกระเป๋าเงินใหม่สแกนบล็อกเชนสำหรับผลลัพธ์และอินพุต P2PKH เก่า มันจำเป็นต้องรู้ว่าควรสแกนกุญแจขนาด 65 ไบต์ (และ commitment ของกุญแจเหล่านั้น) หรือกุญแจขนาด 33 ไบต์ (และ commitment ของกุญแจเหล่านั้น) หากไม่สแกนหาประเภทที่ถูกต้อง อาจทำให้ผู้ใช้ไม่สามารถใช้ยอดคงเหลือทั้งหมดได้ เพื่อแก้ไขปัญหานี้ เมื่อส่งออก private key จากกระเป๋าเงิน WIF ที่ใช้แสดง private key ในกระเป๋าเงินบิตคอยน์รุ่นใหม่จะถูกนำไปใช้แตกต่างกันเล็กน้อยเพื่อบ่งชี้ว่า private key เหล่านี้ถูกใช้ในการสร้าง compressed public key
Legacy: Pay to Script Hash (P2SH)
ตามที่เราได้เห็นในส่วนก่อนหน้านี้ ผู้รับบิตคอยน์ สามารถกำหนดให้การชำระเงินที่ส่งมาให้เขานั้นมีเงื่อนไขบางอย่างในสคริปต์เอาต์พุตได้โดยจะต้องปฏิบัติตามเงื่อนไขเหล่านั้นโดยใช้สคริปต์อินพุตเมื่อเขาใช้จ่ายบิตคอยน์เหล่านั้น ในส่วน IP Addresses: The Original Address for Bitcoin (P2PK) เงื่อนไขก็คือสคริปต์อินพุตต้องให้ลายเซ็นที่เหมาะสม ในส่วน Legacy Addresses for P2PKH นั้นจำเป็นต้องมี public key ที่เหมาะสมด้วย
ส่วนสำหรับผู้ส่งก็จะวางเงื่อนไขที่ผู้รับต้องการในสคริปต์เอาต์พุตที่ใช้จ่ายให้กับผู้รับ โดยผู้รับจะต้องสื่อสารเงื่อนไขเหล่านั้นให้ผู้ส่งทราบ ซึ่งคล้ายกับปัญหาที่บ๊อบต้องสื่อสาร public key ของเขาให้อลิซทราบ และเช่นเดียวกับปัญหานั้นที่ public key อาจมีขนาดค่อนข้างใหญ่ เงื่อนไขที่บ๊อบใช้ก็อาจมีขนาดใหญ่มากเช่นกัน—อาจมีขนาดหลายพันไบต์ นั่นไม่เพียงแต่เป็นข้อมูลหลายพันไบต์ที่ต้องสื่อสารให้อลิซทราบ แต่ยังเป็นข้อมูลหลายพันไบต์ที่เธอต้องจ่ายค่าธรรมเนียมธุรกรรมทุกครั้งที่ต้องการใช้จ่ายเงินให้บ๊อบ อย่างไรก็ตาม การใช้ฟังก์ชันแฮชเพื่อสร้าง commitment ขนาดเล็กสำหรับข้อมูลขนาดใหญ่ก็สามารถนำมาใช้ได้ในกรณีนี้เช่นกัน
ในเวลาต่อมานั้น การอัปเกรด BIP16 สำหรับโปรโตคอลบิตคอยน์ในปี 2012 ได้อนุญาตให้สคริปต์เอาต์พุตสร้าง commitment กับ redemption script (redeem script) ได้ แปลว่าเมื่อบ๊อบใช้จ่ายบิตคอยน์ของเขา ภายในสคริปต์อินพุตของเขานั้นจะต้องให้ redeem script ที่ตรงกับ commitment และข้อมูลที่จำเป็นเพื่อให้เป็นไปตาม redeem script (เช่น ลายเซ็น) เริ่มต้นด้วยการจินตนาการว่าบ๊อบต้องการให้มีลายเซ็นสองอันเพื่อใช้จ่ายบิตคอยน์ของเขา หนึ่งลายเซ็นจากกระเป๋าเงินบนเดสก์ท็อปและอีกหนึ่งจากอุปกรณ์เซ็นแบบฮาร์ดแวร์ เขาใส่เงื่อนไขเหล่านั้นลงใน redeem script:
<public key 1> OP_CHECKSIGVERIFY <public key 2> OP_CHECKSIG
จากนั้นเขาสร้าง commitment กับ redeem script โดยใช้กลไก HASH160 เดียวกับที่ใช้สำหรับ commitment แบบ P2PKH, RIPEMD160(SHA256(script)) commitment นั้นถูกวางไว้ในสคริปต์เอาต์พุตโดยใช้เทมเพลตพิเศษ:OP_HASH160 <commitment> OP_EQUAL
คำเตือน: เมื่อใช้ pay to script hash (P2SH) คุณต้องใช้เทมเพลต P2SH โดยเฉพาะ ซึ่งจะไม่มีข้อมูลหรือเงื่อนไขเพิ่มเติมในสคริปต์เอาต์พุต หากสคริปต์เอาต์พุตไม่ได้เป็น OP_HASH160 <20 ไบต์> OP_EQUAL แน่นอนว่า redeem script จะไม่ถูกใช้และบิตคอยน์ใด ๆ อาจไม่สามารถใช้จ่ายได้หรืออาจถูกใช้จ่ายได้โดยทุกคน (หมายความว่าใครก็สามารถนำไปใช้ได้)
เมื่อบ๊อบต้องการจ่ายเงินที่เขาได้รับผ่าน commitment สำหรับสคริปต์ของเขา เขาจะใช้สคริปต์อินพุตที่รวมถึง redeem script ซึ่งถูกแปลงให้เป็นข้อมูลอีลิเมนต์เดียว นอกจากนี้เขายังให้ลายเซ็นที่จำเป็นเพื่อให้เป็นไปตาม redeem script โดยเรียงลำดับตามที่จะถูกใช้โดย opcodes:
<signature2> <signature1> <redeem script>
เมื่อโหนดของบิตคอยน์ได้รับการใช้จ่ายของบ๊อบพวกมันจะตรวจสอบว่า redeem script ที่ถูกแปลงเป็นค่าแฮชแล้วมีค่าเดียวกันกับ commitment มั้ย หลังจากนั้นพวกมันจะแทนที่มันบนสแต็คด้วยค่าที่ถอดรหัสแล้ว:<signature2> <signature1> <pubkey1> OP_CHECKSIGVERIFY <pubkey2> OP_CHECKSIG
สคริปต์จะถูกประมวลผล และหากผ่านการตรวจสอบและรายละเอียดธุรกรรมอื่น ๆ ทั้งหมดถูกต้อง ธุรกรรมก็จะถือว่าใช้ได้address สำหรับ P2SH ก็ถูกสร้างด้วย base58check เช่นกัน คำนำหน้าเวอร์ชันถูกตั้งเป็น 5 ซึ่งทำให้ที่อยู่ที่เข้ารหัสแล้วขึ้นต้นด้วยเลข 3 ตัวอย่างของที่อยู่ P2SH คือ 3F6i6kwkevjR7AsAd4te2YB2zZyASEm1HM
TIP: P2SH ไม่จำเป็นต้องเหมือนกับธุรกรรมแบบหลายลายเซ็น (multisignature) เสมอไป ถึง address P2SH ส่วนใหญ่ แทนสคริปต์แบบหลายลายเซ็นก็ตาม แต่อาจแทนสคริปต์ที่เข้ารหัสธุรกรรมประเภทอื่น ๆ ได้ด้วย
P2PKH และ P2SH เป็นสองเทมเพลตสคริปต์เท่านั้นที่ใช้กับการเข้ารหัสแบบ base58check พวกมันเป็นที่รู้จักในปัจจุบันว่าเป็น address แบบ legacy และกลายเป็นรูปแบบที่พบน้อยลงเรื่อยๆ address แบบ legacy ถูกแทนที่ด้วยaddress ตระกูล bech32
การโจมตี P2SH แบบ Collision
address ทั้งหมดที่อิงกับฟังก์ชันแฮชมีความเสี่ยงในทางทฤษฎีต่อผู้โจมตีที่อาจค้นพบอินพุตเดียวกันที่สร้างเอาต์พุตฟังก์ชันแฮช (commitment) โดยอิสระ ในกรณีของบิตคอยน์ หากพวกเขาค้นพบอินพุตในวิธีเดียวกับที่ผู้ใช้ดั้งเดิมทำ พวกเขาจะรู้ private key ของผู้ใช้และสามารถใช้จ่ายบิตคอยน์ของผู้ใช้นั้นได้ โอกาสที่ผู้โจมตีจะสร้างอินพุตสำหรับ commitment ที่มีอยู่แล้วโดยอิสระนั้นขึ้นอยู่กับความแข็งแกร่งของอัลกอริทึมแฮช สำหรับอัลกอริทึมที่ปลอดภัย 160 บิตอย่าง HASH160 ความน่าจะเป็นอยู่ที่ 1 ใน 2^160 นี่เรียกว่าการโจมตีแบบ preimage attack
ผู้โจมตีสามารถพยายามสร้างข้อมูลนำเข้าสองชุดที่แตกต่างกัน (เช่น redeem scripts) ที่สร้างการเข้ารหัสแบบเดียวกันได้ สำหรับ address ที่สร้างโดยฝ่ายเดียวทั้งหมด โอกาสที่ผู้โจมตีจะสร้างข้อมูลนำเข้าที่แตกต่างสำหรับการเข้ารหัสที่มีอยู่แล้วมีประมาณ 1 ใน 2^160 สำหรับอัลกอริทึม HASH160 นี่คือการโจมตีแบบ second preimage attack
อย่างไรก็ตาม สถานการณ์จะเปลี่ยนไปเมื่อผู้โจมตีสามารถมีอิทธิพลต่อค่าข้อมูลนำเข้าดั้งเดิมได้ ตัวอย่างเช่น ผู้โจมตีมีส่วนร่วมในการสร้างสคริปต์แบบหลายลายเซ็น (multisignature script) ซึ่งพวกเขาไม่จำเป็นต้องส่ง public key ของตนจนกว่าจะทราบ public key ของฝ่ายอื่นทั้งหมด ในกรณีนั้น ความแข็งแกร่งของอัลกอริทึมการแฮชจะลดลงเหลือรากที่สองของมัน สำหรับ HASH160 ความน่าจะเป็นจะกลายเป็น 1 ใน 2^80 นี่คือการโจมตีแบบ collision attack
เพื่อให้เข้าใจตัวเลขเหล่านี้ในบริบทที่ชัดเจน ข้อมูล ณ ต้นปี 2023 นักขุดบิตคอยน์ทั้งหมดรวมกันสามารถประมวลผลฟังก์ชันแฮชประมาณ 2^80 ทุกชั่วโมง พวกเขาใช้ฟังก์ชันแฮชที่แตกต่างจาก HASH160 ดังนั้นฮาร์ดแวร์ที่มีอยู่จึงไม่สามารถสร้างการโจมตีแบบ collision attack สำหรับมันได้ แต่การมีอยู่ของเครือข่ายบิตคอยน์พิสูจน์ว่าการโจมตีแบบชนกันต่อฟังก์ชัน 160 บิตอย่าง HASH160 สามารถทำได้จริงในทางปฏิบัติ นักขุดบิตคอยน์ได้ลงทุนเทียบเท่ากับหลายพันล้านดอลลาร์สหรัฐในฮาร์ดแวร์พิเศษ ดังนั้นการสร้างการโจมตีแบบ collision attack จึงไม่ใช่เรื่องถูก แต่มีองค์กรที่คาดหวังว่าจะได้รับบิตคอยน์มูลค่าหลายพันล้านดอลลาร์ไปยัง address ที่สร้างโดยกระบวนการที่เกี่ยวข้องกับหลายฝ่าย ซึ่งอาจทำให้การโจมตีนี้มีกำไร
มีโปรโตคอลการเข้ารหัสที่เป็นที่ยอมรับอย่างดีในการป้องกันการโจมตีแบบ collision attack แต่วิธีแก้ปัญหาที่ง่ายโดยไม่ต้องใช้ความรู้พิเศษจากผู้พัฒนากระเป๋าเงินคือการใช้ฟังก์ชันแฮชที่แข็งแกร่งกว่า การอัปเกรดบิตคอยน์ในภายหลังทำให้เป็นไปได้ และ address บิตคอยน์ใหม่ให้ความต้านทานการชนกันอย่างน้อย 128 บิต การดำเนินการแฮช 2^128 ครั้งจะใช้เวลานักขุดบิตคอยน์ปัจจุบันทั้งหมดประมาณ 32 พันล้านปี
แม้ว่าเราไม่เชื่อว่ามีภัยคุกคามเร่งด่วนต่อผู้ที่สร้าง address P2SH ใหม่ แต่เราแนะนำให้กระเป๋าเงินใหม่ทั้งหมดใช้ที่อยู่ประเภทใหม่เพื่อขจัดความกังวลเกี่ยวกับการโจมตีแบบ collision attack ของ P2SH address
Bech32 Addresses
ในปี 2017 โปรโตคอลบิตคอยน์ได้รับการอัปเกรด เพื่อป้องกันไม่ให้ตัวระบุธุรกรรม (txids) ไม่สามารถเปลี่ยนแปลงได้ โดยไม่ได้รับความยินยอมจากผู้ใช้ที่ทำการใช้จ่าย (หรือองค์ประชุมของผู้ลงนามเมื่อต้องมีลายเซ็นหลายรายการ) การอัปเกรดนี้เรียกว่า segregated witness (หรือเรียกสั้นๆ ว่า segwit) ซึ่งยังให้ความสามารถเพิ่มเติมสำหรับข้อมูลธุรกรรมในบล็อกและประโยชน์อื่น ๆ อีกหลายประการ แต่อย่างไรก็ตาม หากมีผู้ใช้เก่าที่ต้องการเข้าถึงประโยชน์ของ segwit โดยตรงต้องยอมรับการชำระเงินไปยังสคริปต์เอาต์พุตใหม่
ตามที่ได้กล่าวไว้ใน p2sh หนึ่งในข้อดีของเอาต์พุตประเภท P2SH คือผู้จ่ายไม่จำเป็นต้องรู้รายละเอียดของสคริปต์ที่ผู้รับใช้ การอัปเกรด segwit ถูกออกแบบมาให้ใช้กลไกนี้ได้ดังเดิม จึง ทำให้ผู้จ่ายสามารถเริ่มเข้าถึงประโยชน์ใหม่ ๆ หลายอย่างได้ทันทีโดยใช้ที่อยู่ P2SH แต่เพื่อให้ผู้รับสามารถเข้าถึงประโยชน์เหล่านั้นได้ พวกเขาจำเป็นจะต้องให้กระเป๋าเงินของผู้จ่ายจ่ายเงินให้เขาโดยใช้สคริปต์ประเภทอื่นแทน ซึ่งจะต้องอาศัยการอัปเกรดกระเป๋าเงินของผู้จ่ายเพื่อรองรับสคริปต์ใหม่เหล่านี้
ในช่วงแรก เหล่านักพัฒนาบิตคอยน์ได้นำเสนอ BIP142 ซึ่งจะยังคงใช้ base58check ร่วมกับไบต์เวอร์ชันใหม่ คล้ายกับการอัปเกรด P2SH แต่การให้กระเป๋าเงินทั้งหมดอัปเกรดไปใช้สคริปต์ใหม่ที่มีเวอร์ชัน base58check ใหม่นั้น คาดว่าจะต้องใช้ความพยายามเกือบเท่ากับการให้พวกเขาอัปเกรดไปใช้รูปแบบ address ที่เป็นแบบใหม่ทั้งหมด ด้วยเหตุนี้้เอง ผู้สนับสนุนบิตคอยน์หลายคนจึงเริ่มออกแบบรูปแบบ address ที่ดีที่สุดเท่าที่เป็นไปได้ พวกเขาระบุปัญหาหลายอย่างกับ base58check ไว้ดังนี้:
- การที่ base58check ใช้อักษรที่มีทั้งตัวพิมพ์ใหญ่และตัวพิมพ์เล็กทำให้ไม่สะดวกในการอ่านออกเสียงหรือคัดลอก ลองอ่าน address แบบเก่าในบทนี้ให้เพื่อนฟังและให้พวกเขาคัดลอก คุณจะสังเกตว่าคุณต้องระบุคำนำหน้าทุกตัวอักษรด้วยคำว่า "ตัวพิมพ์ใหญ่" และ "ตัวพิมพ์เล็ก" และเมื่อคุณตรวจสอบสิ่งที่พวกเขาเขียน คุณจะพบว่าตัวพิมพ์ใหญ่และตัวพิมพ์เล็กของตัวอักษรบางตัวอาจดูคล้ายกันในลายมือของคนส่วนใหญ่
- รูปแบบนี้สามารถตรวจจับข้อผิดพลาดได้ แต่ไม่สามารถช่วยผู้ใช้แก้ไขข้อผิดพลาดเหล่านั้น ตัวอย่างเช่น หากคุณสลับตำแหน่งตัวอักษรสองตัวโดยไม่ตั้งใจเมื่อป้อน address ด้วยตนเอง กระเป๋าเงินของคุณจะเตือนว่ามีข้อผิดพลาดเกิดขึ้นแน่นอน แต่จะไม่ช่วยให้คุณค้นพบว่าข้อผิดพลาดอยู่ที่ไหน คุณอาจต้องใช้เวลาหลายนาทีที่น่าหงุดหงิดเพื่อค้นหาข้อผิดพลาดในที่สุด
- การใช้ตัวอักษรที่มีทั้งตัวพิมพ์ใหญ่และตัวพิมพ์เล็กยังต้องใช้พื้นที่เพิ่มเติมในการเข้ารหัสใน QR code ซึ่งนิยมใช้ในการแชร์ address และ invoice ระหว่างกระเป๋าเงิน พื้นที่เพิ่มเติมนี้หมายความว่า QR code จำเป็นต้องมีขนาดใหญ่ขึ้นที่ความละเอียดเดียวกัน หรือไม่เช่นนั้นก็จะยากต่อการสแกนอย่างรวดเร็ว
- การที่ต้องการให้กระเป๋าเงินผู้จ่ายทุกใบอัปเกรดเพื่อรองรับคุณสมบัติโปรโตคอลใหม่ เช่น P2SH และ segwit แม้ว่าการอัปเกรดเองอาจไม่ต้องใช้โค้ดมากนัก แต่ประสบการณ์แสดงให้เห็นว่าผู้พัฒนากระเป๋าเงินหลายรายมักยุ่งกับงานอื่น ๆ และบางครั้งอาจล่าช้าในการอัปเกรดเป็นเวลาหลายปี สิ่งนี้ส่งผลเสียต่อทุกคนที่ต้องการใช้คุณสมบัติใหม่ ๆ เหล่านี้
นักพัฒนาที่ทำงานเกี่ยวกับรูปแบบ address สำหรับ segwit ได้พบวิธีแก้ปัญหาเหล่านี้ทั้งหมดในรูปแบบ address แบบใหม่ที่เรียกว่า bech32 (ออกเสียงด้วย "ch" อ่อน เช่นใน "เบช สามสิบสอง") คำว่า "bech" มาจาก BCH ซึ่งเป็นอักษรย่อของบุคคลสามคนที่ค้นพบรหัสวนนี้ในปี 1959 และ 1960 ซึ่งเป็นพื้นฐานของ bech32 ส่วน "32" หมายถึงจำนวนตัวอักษรในชุดตัวอักษร bech32 (คล้ายกับ 58 ใน base58check):
-
Bech32 ใช้เฉพาะตัวเลขและตัวอักษรรูปแบบเดียว (โดยปกติจะแสดงเป็นตัวพิมพ์เล็ก) แม้ว่าชุดตัวอักษรของมันจะมีขนาดเกือบครึ่งหนึ่งของชุดตัวอักษรใน base58check ก็ตามแต่ address bech32 สำหรับสคริปต์ pay to witness public key hash (P2WPKH) ก็ยังยาวกว่า legacy address และมีขนาดเท่ากันกับสคริปต์ P2PKH
-
Bech32 สามารถทั้งตรวจจับและช่วยแก้ไขข้อผิดพลาดได้ ใน address ที่มีความยาวตามที่คาดหวังได้ และสามารถรับประกันทางคณิตศาสตร์ได้ว่าจะตรวจพบข้อผิดพลาดใด ๆ ที่ส่งผลกระทบต่อตัวอักษร 4 ตัวหรือน้อยกว่า ซึ่งเชื่อถือได้มากกว่า base58check ส่วนสำหรับข้อผิดพลาดที่ยาวกว่านั้น จะไม่สามารถตรวจพบได้ (โอกาสเกิดน้อยกว่าหนึ่งครั้งในหนึ่งพันล้าน) ซึ่งมีความเชื่อถือได้ประมาณเท่ากับ base58check ยิ่งไปกว่านั้น สำหรับ adddress ที่พิมพ์โดยมีข้อผิดพลาดเพียงเล็กน้อย มันสามารถบอกผู้ใช้ได้ว่าข้อผิดพลาดเหล่านั้นเกิดขึ้นที่ไหน ช่วยให้พวกเขาสามารถแก้ไขข้อผิดพลาดจากการคัดลอกเล็ก ๆ น้อย ๆ ได้อย่างรวดเร็ว

ตัวอย่างที่ 3 Bech32 address ที่มีข้อผิดพลาด Address: bc1p9nh05ha8wrljf7ru236awn4t2x0d5ctkkywmv9sclnm4t0av2vgs4k3au7 ข้อผิดพลาดที่ตรวจพบแสดงเป็นตัวหนาและขีดเส้นใต้ สร้างโดยใช้โปรแกรมสาธิตการถอดรหัส bech32 address
-
bech32 address นิยมเขียนด้วยตัวอักษรพิมพ์เล็กเท่านั้น แต่ตัวอักษรพิมพ์เล็กเหล่านี้สามารถแทนที่ด้วยตัวอักษรพิมพ์ใหญ่ก่อนการเข้ารหัส address ในรหัส QR ได้ วิธีนี้ช่วยให้สามารถใช้โหมดการเข้ารหัส QR แบบพิเศษที่ใช้พื้นที่น้อยกว่า คุณจะสังเกตเห็นความแตกต่างในขนาดและความซับซ้อนของรหัส QR ทั้งสองสำหรับที่อยู่เดียวกันในรูปภาพข้างล่างนี้
- Bech32 ใช้ประโยชน์จากกลไกการอัปเกรดที่ออกแบบมาเป็นส่วนหนึ่งของ segwit เพื่อทำให้กระเป๋าเงินผู้จ่ายสามารถจ่ายเงินไปยังประเภทเอาต์พุตที่ยังไม่ได้ใช้งานได้ โดยมีเป้าหมายคือการอนุญาตให้นักพัฒนาสร้างกระเป๋าเงินในวันนี้ที่สามารถใช้จ่ายไปยัง bech32 address และทำให้กระเป๋าเงินนั้นยังคงสามารถใช้จ่ายไปยัง bech32address ได้สำหรับผู้ใช้คุณสมบัติใหม่ที่เพิ่มในการอัปเกรดโปรโตคอลในอนาคต โดยที่มีความหวังว่าเราอาจไม่จำเป็นต้องผ่านรอบการอัปเกรดทั้งระบบอีกต่อไป ซึ่งจำเป็นสำหรับการให้ผู้คนใช้งาน P2SH และ segwit ได้อย่างเต็มรูปแบบ

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

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

2025-05-20 14:22:05Ikigai means "the meaning of life" or "the reason for being." Why were we born? What are we living for? When work is not seen as something separate from life.
The Japanese believe that everyone has their own ikigai. Those who discover it find meaning and value in life, leading to greater happiness, better moods, and a more fulfilling world.
Today, there are many books about ikigai, but the first one written by a Japanese author is:
“The Little Book of Ikigai: The Secret Japanese Way to Live a Happy and Long Life” by Ken Mogi (Thai translation by Wuttichai Krisanaprakankit)
Come explore the true world of ikigai through this Japanese neuroscientist’s insights, conveyed through conversations that challenge the idea of ikigai as something grand—showing instead that it starts with small personal joys.
Ken Mogi says that Jiro Ono, a 94-year-old sushi chef who still makes sushi today, was his inspiration for writing the book.
This sushi chef did not start the job out of passion or talent—but he dedicated every piece of sushi to bring happiness to his customers. That, Ken says, is the essence of ikigai.
Strangely, the word “ikigai” is not often used in daily conversations in Japan.
Because it’s something so natural that it doesn’t need to be said. In today’s world, we often talk about how to succeed, how to get promoted, how to become a CEO. But for the Japanese, success isn’t everything.
For example, many Japanese people are deeply passionate about hobbies or have kodawari. Others might not care what those hobbies are—as long as the person seems happy, that’s enough. Some are obsessed with trains, manga, or anime. These people don’t need fame or recognition from society. If they’re happy in their own way, that’s perfectly okay.
Kodawari means a deep dedication or meticulous attention to something. For example, someone obsessed with stationery might spend a lot of time selecting the perfect pens, notebooks, or pencils. They’ll research, analyze, and experiment to find the tools they love most.
Everyone’s ikigai can be different, because people value different things and live differently.
Ikigai is about diversity. Japanese society encourages children to discover their own ikigai. They don’t tell kids to pursue jobs only because they pay well. If you ask students what jobs they want, they rarely say it’s about money first.
Ikigai is not the same as "success." The Japanese know that life isn’t just about being successful. Ikigai matters more. You could be successful but lack ikigai. Conversely, you might not be “successful” but still have ikigai—and you might be happier.
Ken Mogi defines success as something society acknowledges and rewards. But ikigai comes from your own heart and personal happiness. Others may not recognize it as success, but that doesn’t matter.
Ikigai is personal. We can be happy in our own way. We don’t judge others’ happiness—let them find joy in their own path.
The key to ikigai is finding small moments of happiness, even from little things. For example, when Ken was a child, he loved studying butterflies. Now, when he’s out jogging and sees a beautiful butterfly, he feels ikigai. Or sometimes, it comes from small amusing moments—like hearing a child tell his dad, “Dad, you have to do it this way!”
So, if we want to find our own ikigai, where do we start? Start with noticing small pleasures in daily life. That’s the easiest place to begin.
In the brain, there's a chemical called dopamine. When we achieve even small things, dopamine is released, creating happiness. That’s why enjoying small things is so important.
For some, ikigai might seem hard to grasp—especially if life is difficult, if they feel hopeless or lack self-worth. So begin with tiny moments of joy.
Is it the same as positive thinking? Ikigai is a part of that. But when we talk about “positive thinking,” it can feel like pressure to some people. So instead, just notice small joys: making your morning coffee, running in the rain.
Lessons from Ken Mogi:
-
Ikigai is not about chasing success or wealth, but about feeling happiness in your own life, which gives your life personal meaning.
-
Ikigai is not defined by society. Everyone’s ikigai is different. Each person can be happy in their own way.
-
**Don’t judge or force others—**children, partners—to live how you think is right. Respect diversity.
-
Smile at people who are enjoying their ikigai, and support them if they struggle.
-
Ikigai exists on two levels:
-
Big ikigai: life purpose or work values.
-
Small ikigai: tiny joys in everyday life.
-
Ikigai starts with noticing small pleasures today.

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

2025-01-21 01:51:46Bitcoin: Um sistema de dinheiro eletrônico direto entre pessoas.
Satoshi Nakamoto

www.bitcoin.org
Resumo
O Bitcoin é uma forma de dinheiro digital que permite pagamentos diretos entre pessoas, sem a necessidade de um banco ou instituição financeira. Ele resolve um problema chamado gasto duplo, que ocorre quando alguém tenta gastar o mesmo dinheiro duas vezes. Para evitar isso, o Bitcoin usa uma rede descentralizada onde todos trabalham juntos para verificar e registrar as transações.
As transações são registradas em um livro público chamado blockchain, protegido por uma técnica chamada Prova de Trabalho. Essa técnica cria uma cadeia de registros que não pode ser alterada sem refazer todo o trabalho já feito. Essa cadeia é mantida pelos computadores que participam da rede, e a mais longa é considerada a verdadeira.
Enquanto a maior parte do poder computacional da rede for controlada por participantes honestos, o sistema continuará funcionando de forma segura. A rede é flexível, permitindo que qualquer pessoa entre ou saia a qualquer momento, sempre confiando na cadeia mais longa como prova do que aconteceu.
1. Introdução
Hoje, quase todos os pagamentos feitos pela internet dependem de bancos ou empresas como processadores de pagamento (cartões de crédito, por exemplo) para funcionar. Embora esse sistema seja útil, ele tem problemas importantes porque é baseado em confiança.
Primeiro, essas empresas podem reverter pagamentos, o que é útil em caso de erros, mas cria custos e incertezas. Isso faz com que pequenas transações, como pagar centavos por um serviço, se tornem inviáveis. Além disso, os comerciantes são obrigados a desconfiar dos clientes, pedindo informações extras e aceitando fraudes como algo inevitável.
Esses problemas não existem no dinheiro físico, como o papel-moeda, onde o pagamento é final e direto entre as partes. No entanto, não temos como enviar dinheiro físico pela internet sem depender de um intermediário confiável.
O que precisamos é de um sistema de pagamento eletrônico baseado em provas matemáticas, não em confiança. Esse sistema permitiria que qualquer pessoa enviasse dinheiro diretamente para outra, sem depender de bancos ou processadores de pagamento. Além disso, as transações seriam irreversíveis, protegendo vendedores contra fraudes, mas mantendo a possibilidade de soluções para disputas legítimas.
Neste documento, apresentamos o Bitcoin, que resolve o problema do gasto duplo usando uma rede descentralizada. Essa rede cria um registro público e protegido por cálculos matemáticos, que garante a ordem das transações. Enquanto a maior parte da rede for controlada por pessoas honestas, o sistema será seguro contra ataques.
2. Transações
Para entender como funciona o Bitcoin, é importante saber como as transações são realizadas. Imagine que você quer transferir uma "moeda digital" para outra pessoa. No sistema do Bitcoin, essa "moeda" é representada por uma sequência de registros que mostram quem é o atual dono. Para transferi-la, você adiciona um novo registro comprovando que agora ela pertence ao próximo dono. Esse registro é protegido por um tipo especial de assinatura digital.
O que é uma assinatura digital?
Uma assinatura digital é como uma senha secreta, mas muito mais segura. No Bitcoin, cada usuário tem duas chaves: uma "chave privada", que é secreta e serve para criar a assinatura, e uma "chave pública", que pode ser compartilhada com todos e é usada para verificar se a assinatura é válida. Quando você transfere uma moeda, usa sua chave privada para assinar a transação, provando que você é o dono. A próxima pessoa pode usar sua chave pública para confirmar isso.
Como funciona na prática?
Cada "moeda" no Bitcoin é, na verdade, uma cadeia de assinaturas digitais. Vamos imaginar o seguinte cenário:
- A moeda está com o Dono 0 (você). Para transferi-la ao Dono 1, você assina digitalmente a transação com sua chave privada. Essa assinatura inclui o código da transação anterior (chamado de "hash") e a chave pública do Dono 1.
- Quando o Dono 1 quiser transferir a moeda ao Dono 2, ele assinará a transação seguinte com sua própria chave privada, incluindo também o hash da transação anterior e a chave pública do Dono 2.
- Esse processo continua, formando uma "cadeia" de transações. Qualquer pessoa pode verificar essa cadeia para confirmar quem é o atual dono da moeda.
Resolvendo o problema do gasto duplo
Um grande desafio com moedas digitais é o "gasto duplo", que é quando uma mesma moeda é usada em mais de uma transação. Para evitar isso, muitos sistemas antigos dependiam de uma entidade central confiável, como uma casa da moeda, que verificava todas as transações. No entanto, isso criava um ponto único de falha e centralizava o controle do dinheiro.
O Bitcoin resolve esse problema de forma inovadora: ele usa uma rede descentralizada onde todos os participantes (os "nós") têm acesso a um registro completo de todas as transações. Cada nó verifica se as transações são válidas e se a moeda não foi gasta duas vezes. Quando a maioria dos nós concorda com a validade de uma transação, ela é registrada permanentemente na blockchain.
Por que isso é importante?
Essa solução elimina a necessidade de confiar em uma única entidade para gerenciar o dinheiro, permitindo que qualquer pessoa no mundo use o Bitcoin sem precisar de permissão de terceiros. Além disso, ela garante que o sistema seja seguro e resistente a fraudes.
3. Servidor Timestamp
Para assegurar que as transações sejam realizadas de forma segura e transparente, o sistema Bitcoin utiliza algo chamado de "servidor de registro de tempo" (timestamp). Esse servidor funciona como um registro público que organiza as transações em uma ordem específica.
Ele faz isso agrupando várias transações em blocos e criando um código único chamado "hash". Esse hash é como uma impressão digital que representa todo o conteúdo do bloco. O hash de cada bloco é amplamente divulgado, como se fosse publicado em um jornal ou em um fórum público.
Esse processo garante que cada bloco de transações tenha um registro de quando foi criado e que ele existia naquele momento. Além disso, cada novo bloco criado contém o hash do bloco anterior, formando uma cadeia contínua de blocos conectados — conhecida como blockchain.
Com isso, se alguém tentar alterar qualquer informação em um bloco anterior, o hash desse bloco mudará e não corresponderá ao hash armazenado no bloco seguinte. Essa característica torna a cadeia muito segura, pois qualquer tentativa de fraude seria imediatamente detectada.
O sistema de timestamps é essencial para provar a ordem cronológica das transações e garantir que cada uma delas seja única e autêntica. Dessa forma, ele reforça a segurança e a confiança na rede Bitcoin.
4. Prova-de-Trabalho
Para implementar o registro de tempo distribuído no sistema Bitcoin, utilizamos um mecanismo chamado prova-de-trabalho. Esse sistema é semelhante ao Hashcash, desenvolvido por Adam Back, e baseia-se na criação de um código único, o "hash", por meio de um processo computacionalmente exigente.
A prova-de-trabalho envolve encontrar um valor especial que, quando processado junto com as informações do bloco, gere um hash que comece com uma quantidade específica de zeros. Esse valor especial é chamado de "nonce". Encontrar o nonce correto exige um esforço significativo do computador, porque envolve tentativas repetidas até que a condição seja satisfeita.
Esse processo é importante porque torna extremamente difícil alterar qualquer informação registrada em um bloco. Se alguém tentar mudar algo em um bloco, seria necessário refazer o trabalho de computação não apenas para aquele bloco, mas também para todos os blocos que vêm depois dele. Isso garante a segurança e a imutabilidade da blockchain.
A prova-de-trabalho também resolve o problema de decidir qual cadeia de blocos é a válida quando há múltiplas cadeias competindo. A decisão é feita pela cadeia mais longa, pois ela representa o maior esforço computacional já realizado. Isso impede que qualquer indivíduo ou grupo controle a rede, desde que a maioria do poder de processamento seja mantida por participantes honestos.
Para garantir que o sistema permaneça eficiente e equilibrado, a dificuldade da prova-de-trabalho é ajustada automaticamente ao longo do tempo. Se novos blocos estiverem sendo gerados rapidamente, a dificuldade aumenta; se estiverem sendo gerados muito lentamente, a dificuldade diminui. Esse ajuste assegura que novos blocos sejam criados aproximadamente a cada 10 minutos, mantendo o sistema estável e funcional.
5. Rede
A rede Bitcoin é o coração do sistema e funciona de maneira distribuída, conectando vários participantes (ou nós) para garantir o registro e a validação das transações. Os passos para operar essa rede são:
-
Transmissão de Transações: Quando alguém realiza uma nova transação, ela é enviada para todos os nós da rede. Isso é feito para garantir que todos estejam cientes da operação e possam validá-la.
-
Coleta de Transações em Blocos: Cada nó agrupa as novas transações recebidas em um "bloco". Este bloco será preparado para ser adicionado à cadeia de blocos (a blockchain).
-
Prova-de-Trabalho: Os nós competem para resolver a prova-de-trabalho do bloco, utilizando poder computacional para encontrar um hash válido. Esse processo é como resolver um quebra-cabeça matemático difícil.
-
Envio do Bloco Resolvido: Quando um nó encontra a solução para o bloco (a prova-de-trabalho), ele compartilha esse bloco com todos os outros nós na rede.
-
Validação do Bloco: Cada nó verifica o bloco recebido para garantir que todas as transações nele contidas sejam válidas e que nenhuma moeda tenha sido gasta duas vezes. Apenas blocos válidos são aceitos.
-
Construção do Próximo Bloco: Os nós que aceitaram o bloco começam a trabalhar na criação do próximo bloco, utilizando o hash do bloco aceito como base (hash anterior). Isso mantém a continuidade da cadeia.
Resolução de Conflitos e Escolha da Cadeia Mais Longa
Os nós sempre priorizam a cadeia mais longa, pois ela representa o maior esforço computacional já realizado, garantindo maior segurança. Se dois blocos diferentes forem compartilhados simultaneamente, os nós trabalharão no primeiro bloco recebido, mas guardarão o outro como uma alternativa. Caso o segundo bloco eventualmente forme uma cadeia mais longa (ou seja, tenha mais blocos subsequentes), os nós mudarão para essa nova cadeia.
Tolerância a Falhas
A rede é robusta e pode lidar com mensagens que não chegam a todos os nós. Uma transação não precisa alcançar todos os nós de imediato; basta que chegue a um número suficiente deles para ser incluída em um bloco. Da mesma forma, se um nó não receber um bloco em tempo hábil, ele pode solicitá-lo ao perceber que está faltando quando o próximo bloco é recebido.
Esse mecanismo descentralizado permite que a rede Bitcoin funcione de maneira segura, confiável e resiliente, sem depender de uma autoridade central.
6. Incentivo
O incentivo é um dos pilares fundamentais que sustenta o funcionamento da rede Bitcoin, garantindo que os participantes (nós) continuem operando de forma honesta e contribuindo com recursos computacionais. Ele é estruturado em duas partes principais: a recompensa por mineração e as taxas de transação.
Recompensa por Mineração
Por convenção, o primeiro registro em cada bloco é uma transação especial que cria novas moedas e as atribui ao criador do bloco. Essa recompensa incentiva os mineradores a dedicarem poder computacional para apoiar a rede. Como não há uma autoridade central para emitir moedas, essa é a maneira pela qual novas moedas entram em circulação. Esse processo pode ser comparado ao trabalho de garimpeiros, que utilizam recursos para colocar mais ouro em circulação. No caso do Bitcoin, o "recurso" consiste no tempo de CPU e na energia elétrica consumida para resolver a prova-de-trabalho.
Taxas de Transação
Além da recompensa por mineração, os mineradores também podem ser incentivados pelas taxas de transação. Se uma transação utiliza menos valor de saída do que o valor de entrada, a diferença é tratada como uma taxa, que é adicionada à recompensa do bloco contendo essa transação. Com o passar do tempo e à medida que o número de moedas em circulação atinge o limite predeterminado, essas taxas de transação se tornam a principal fonte de incentivo, substituindo gradualmente a emissão de novas moedas. Isso permite que o sistema opere sem inflação, uma vez que o número total de moedas permanece fixo.
Incentivo à Honestidade
O design do incentivo também busca garantir que os participantes da rede mantenham um comportamento honesto. Para um atacante que consiga reunir mais poder computacional do que o restante da rede, ele enfrentaria duas escolhas:
- Usar esse poder para fraudar o sistema, como reverter transações e roubar pagamentos.
- Seguir as regras do sistema, criando novos blocos e recebendo recompensas legítimas.
A lógica econômica favorece a segunda opção, pois um comportamento desonesto prejudicaria a confiança no sistema, diminuindo o valor de todas as moedas, incluindo aquelas que o próprio atacante possui. Jogar dentro das regras não apenas maximiza o retorno financeiro, mas também preserva a validade e a integridade do sistema.
Esse mecanismo garante que os incentivos econômicos estejam alinhados com o objetivo de manter a rede segura, descentralizada e funcional ao longo do tempo.
7. Recuperação do Espaço em Disco
Depois que uma moeda passa a estar protegida por muitos blocos na cadeia, as informações sobre as transações antigas que a geraram podem ser descartadas para economizar espaço em disco. Para que isso seja possível sem comprometer a segurança, as transações são organizadas em uma estrutura chamada "árvore de Merkle". Essa árvore funciona como um resumo das transações: em vez de armazenar todas elas, guarda apenas um "hash raiz", que é como uma assinatura compacta que representa todo o grupo de transações.
Os blocos antigos podem, então, ser simplificados, removendo as partes desnecessárias dessa árvore. Apenas a raiz do hash precisa ser mantida no cabeçalho do bloco, garantindo que a integridade dos dados seja preservada, mesmo que detalhes específicos sejam descartados.
Para exemplificar: imagine que você tenha vários recibos de compra. Em vez de guardar todos os recibos, você cria um documento e lista apenas o valor total de cada um. Mesmo que os recibos originais sejam descartados, ainda é possível verificar a soma com base nos valores armazenados.
Além disso, o espaço ocupado pelos blocos em si é muito pequeno. Cada bloco sem transações ocupa apenas cerca de 80 bytes. Isso significa que, mesmo com blocos sendo gerados a cada 10 minutos, o crescimento anual em espaço necessário é insignificante: apenas 4,2 MB por ano. Com a capacidade de armazenamento dos computadores crescendo a cada ano, esse espaço continuará sendo trivial, garantindo que a rede possa operar de forma eficiente sem problemas de armazenamento, mesmo a longo prazo.
8. Verificação de Pagamento Simplificada
É possível confirmar pagamentos sem a necessidade de operar um nó completo da rede. Para isso, o usuário precisa apenas de uma cópia dos cabeçalhos dos blocos da cadeia mais longa (ou seja, a cadeia com maior esforço de trabalho acumulado). Ele pode verificar a validade de uma transação ao consultar os nós da rede até obter a confirmação de que tem a cadeia mais longa. Para isso, utiliza-se o ramo Merkle, que conecta a transação ao bloco em que ela foi registrada.
Entretanto, o método simplificado possui limitações: ele não pode confirmar uma transação isoladamente, mas sim assegurar que ela ocupa um lugar específico na cadeia mais longa. Dessa forma, se um nó da rede aprova a transação, os blocos subsequentes reforçam essa aceitação.
A verificação simplificada é confiável enquanto a maioria dos nós da rede for honesta. Contudo, ela se torna vulnerável caso a rede seja dominada por um invasor. Nesse cenário, um atacante poderia fabricar transações fraudulentas que enganariam o usuário temporariamente até que o invasor obtivesse controle completo da rede.
Uma estratégia para mitigar esse risco é configurar alertas nos softwares de nós completos. Esses alertas identificam blocos inválidos, sugerindo ao usuário baixar o bloco completo para confirmar qualquer inconsistência. Para maior segurança, empresas que realizam pagamentos frequentes podem preferir operar seus próprios nós, reduzindo riscos e permitindo uma verificação mais direta e confiável.
9. Combinando e Dividindo Valor
No sistema Bitcoin, cada unidade de valor é tratada como uma "moeda" individual, mas gerenciar cada centavo como uma transação separada seria impraticável. Para resolver isso, o Bitcoin permite que valores sejam combinados ou divididos em transações, facilitando pagamentos de qualquer valor.
Entradas e Saídas
Cada transação no Bitcoin é composta por:
- Entradas: Representam os valores recebidos em transações anteriores.
- Saídas: Correspondem aos valores enviados, divididos entre os destinatários e, eventualmente, o troco para o remetente.
Normalmente, uma transação contém:
- Uma única entrada com valor suficiente para cobrir o pagamento.
- Ou várias entradas combinadas para atingir o valor necessário.
O valor total das saídas nunca excede o das entradas, e a diferença (se houver) pode ser retornada ao remetente como troco.
Exemplo Prático
Imagine que você tem duas entradas:
- 0,03 BTC
- 0,07 BTC
Se deseja enviar 0,08 BTC para alguém, a transação terá:
- Entrada: As duas entradas combinadas (0,03 + 0,07 BTC = 0,10 BTC).
- Saídas: Uma para o destinatário (0,08 BTC) e outra como troco para você (0,02 BTC).
Essa flexibilidade permite que o sistema funcione sem precisar manipular cada unidade mínima individualmente.
Difusão e Simplificação
A difusão de transações, onde uma depende de várias anteriores e assim por diante, não representa um problema. Não é necessário armazenar ou verificar o histórico completo de uma transação para utilizá-la, já que o registro na blockchain garante sua integridade.
10. Privacidade
O modelo bancário tradicional oferece um certo nível de privacidade, limitando o acesso às informações financeiras apenas às partes envolvidas e a um terceiro confiável (como bancos ou instituições financeiras). No entanto, o Bitcoin opera de forma diferente, pois todas as transações são publicamente registradas na blockchain. Apesar disso, a privacidade pode ser mantida utilizando chaves públicas anônimas, que desvinculam diretamente as transações das identidades das partes envolvidas.
Fluxo de Informação
- No modelo tradicional, as transações passam por um terceiro confiável que conhece tanto o remetente quanto o destinatário.
- No Bitcoin, as transações são anunciadas publicamente, mas sem revelar diretamente as identidades das partes. Isso é comparável a dados divulgados por bolsas de valores, onde informações como o tempo e o tamanho das negociações (a "fita") são públicas, mas as identidades das partes não.
Protegendo a Privacidade
Para aumentar a privacidade no Bitcoin, são adotadas as seguintes práticas:
- Chaves Públicas Anônimas: Cada transação utiliza um par de chaves diferentes, dificultando a associação com um proprietário único.
- Prevenção de Ligação: Ao usar chaves novas para cada transação, reduz-se a possibilidade de links evidentes entre múltiplas transações realizadas pelo mesmo usuário.
Riscos de Ligação
Embora a privacidade seja fortalecida, alguns riscos permanecem:
- Transações multi-entrada podem revelar que todas as entradas pertencem ao mesmo proprietário, caso sejam necessárias para somar o valor total.
- O proprietário da chave pode ser identificado indiretamente por transações anteriores que estejam conectadas.
11. Cálculos
Imagine que temos um sistema onde as pessoas (ou computadores) competem para adicionar informações novas (blocos) a um grande registro público (a cadeia de blocos ou blockchain). Este registro é como um livro contábil compartilhado, onde todos podem verificar o que está escrito.
Agora, vamos pensar em um cenário: um atacante quer enganar o sistema. Ele quer mudar informações já registradas para beneficiar a si mesmo, por exemplo, desfazendo um pagamento que já fez. Para isso, ele precisa criar uma versão alternativa do livro contábil (a cadeia de blocos dele) e convencer todos os outros participantes de que essa versão é a verdadeira.
Mas isso é extremamente difícil.
Como o Ataque Funciona
Quando um novo bloco é adicionado à cadeia, ele depende de cálculos complexos que levam tempo e esforço. Esses cálculos são como um grande quebra-cabeça que precisa ser resolvido.
- Os “bons jogadores” (nós honestos) estão sempre trabalhando juntos para resolver esses quebra-cabeças e adicionar novos blocos à cadeia verdadeira.
- O atacante, por outro lado, precisa resolver quebra-cabeças sozinho, tentando “alcançar” a cadeia honesta para que sua versão alternativa pareça válida.
Se a cadeia honesta já está vários blocos à frente, o atacante começa em desvantagem, e o sistema está projetado para que a dificuldade de alcançá-los aumente rapidamente.
A Corrida Entre Cadeias
Você pode imaginar isso como uma corrida. A cada bloco novo que os jogadores honestos adicionam à cadeia verdadeira, eles se distanciam mais do atacante. Para vencer, o atacante teria que resolver os quebra-cabeças mais rápido que todos os outros jogadores honestos juntos.
Suponha que:
- A rede honesta tem 80% do poder computacional (ou seja, resolve 8 de cada 10 quebra-cabeças).
- O atacante tem 20% do poder computacional (ou seja, resolve 2 de cada 10 quebra-cabeças).
Cada vez que a rede honesta adiciona um bloco, o atacante tem que "correr atrás" e resolver mais quebra-cabeças para alcançar.
Por Que o Ataque Fica Cada Vez Mais Improvável?
Vamos usar uma fórmula simples para mostrar como as chances de sucesso do atacante diminuem conforme ele precisa "alcançar" mais blocos:
P = (q/p)^z
- q é o poder computacional do atacante (20%, ou 0,2).
- p é o poder computacional da rede honesta (80%, ou 0,8).
- z é a diferença de blocos entre a cadeia honesta e a cadeia do atacante.
Se o atacante está 5 blocos atrás (z = 5):
P = (0,2 / 0,8)^5 = (0,25)^5 = 0,00098, (ou, 0,098%)
Isso significa que o atacante tem menos de 0,1% de chance de sucesso — ou seja, é muito improvável.
Se ele estiver 10 blocos atrás (z = 10):
P = (0,2 / 0,8)^10 = (0,25)^10 = 0,000000095, (ou, 0,0000095%).
Neste caso, as chances de sucesso são praticamente nulas.
Um Exemplo Simples
Se você jogar uma moeda, a chance de cair “cara” é de 50%. Mas se precisar de 10 caras seguidas, sua chance já é bem menor. Se precisar de 20 caras seguidas, é quase impossível.
No caso do Bitcoin, o atacante precisa de muito mais do que 20 caras seguidas. Ele precisa resolver quebra-cabeças extremamente difíceis e alcançar os jogadores honestos que estão sempre à frente. Isso faz com que o ataque seja inviável na prática.
Por Que Tudo Isso é Seguro?
- A probabilidade de sucesso do atacante diminui exponencialmente. Isso significa que, quanto mais tempo passa, menor é a chance de ele conseguir enganar o sistema.
- A cadeia verdadeira (honesta) está protegida pela força da rede. Cada novo bloco que os jogadores honestos adicionam à cadeia torna mais difícil para o atacante alcançar.
E Se o Atacante Tentar Continuar?
O atacante poderia continuar tentando indefinidamente, mas ele estaria gastando muito tempo e energia sem conseguir nada. Enquanto isso, os jogadores honestos estão sempre adicionando novos blocos, tornando o trabalho do atacante ainda mais inútil.
Assim, o sistema garante que a cadeia verdadeira seja extremamente segura e que ataques sejam, na prática, impossíveis de ter sucesso.
12. Conclusão
Propusemos um sistema de transações eletrônicas que elimina a necessidade de confiança, baseando-se em assinaturas digitais e em uma rede peer-to-peer que utiliza prova de trabalho. Isso resolve o problema do gasto duplo, criando um histórico público de transações imutável, desde que a maioria do poder computacional permaneça sob controle dos participantes honestos. A rede funciona de forma simples e descentralizada, com nós independentes que não precisam de identificação ou coordenação direta. Eles entram e saem livremente, aceitando a cadeia de prova de trabalho como registro do que ocorreu durante sua ausência. As decisões são tomadas por meio do poder de CPU, validando blocos legítimos, estendendo a cadeia e rejeitando os inválidos. Com este mecanismo de consenso, todas as regras e incentivos necessários para o funcionamento seguro e eficiente do sistema são garantidos.

2025-05-21 02:04:25This article is slightly outside my normal writing focus. But it’s something everyone deserves to know, and take advantage of if they like. Before you click away, this isn’t a sports betting “system” or “strategy”. This is for anyone living in or near a state that has legalized online sports betting. It’s a way to take advantage of the new customer sign up bonuses these online sportsbooks give, by using free online tools to convert those bonuses into $2,000 or more in cash per person, depending on your state. It doesn’t require you to know anything whatsoever about sports, gambling, sports betting, odds, math, or anything like that. It doesn’t involve taking risks with your money. All you need is some capital (around $3-5,000 would be ideal), a smartphone, a legal sports betting state, and this guide.
Concepts and Principles
Online sports betting is now legal in 30 US states. You can check legality in your state on the map here. If you’re in a state with legal mobile betting, or close enough that you’d be willing to drive there, you can benefit from this guide.
Most states with legalized betting have multiple different sports books competing for customers. To attract new customers, many of them offer various types of bonus offers when you initially sign up. The idea is that once you sign up and place a bet, you’re likely to continue betting in the future. So the sportsbook doesn’t mind losing money on your first wager, because they’ll make it back over time. That leaves an opportunity for someone to just take the free money and leave, if they want to do that. It’s completely legal, and if you follow this guide, also risk free.
The bonuses vary in size, but are usually larger the first few months after a state legalizes online betting, since sportsbooks are competing heavily to attract the new customers to their site. But most states will have a combined $3-5,000 in bonuses available at any time across 4-8 sportsbooks. You can find the available offers in your state by searching “covers sports betting promo offers \
”. For example for Maryland, we’d end up up at covers.com on a page like this. The basic concept is that we open accounts on multiple sites, sign up for their bonus offers, then bet both sides of the same sports game but on 2 different sites. That way it doesn’t matter which team wins, we collect the free bonus money with no risk.
Actually doing it is a bit more nuanced, but I’ll explain it step by step and illustrate with plenty of screenshots to make sure you can follow along.
First, you want to find the offers for your state, and sign up for the sites with the offers you want to convert. For Maryland, if we scroll on down at covers.com, we’ll find this list of offers.
The larger offers are of course more worthwhile, so if I were in Maryland, I would first sign up for Caesars, DraftKings, BetMGM, and ESPN BET. Since you’ll also want another site to hedge your bets, I’d also sign up for FanDuel. You can download their apps, set up your accounts, and familiarize yourself with the deposit methods that are available.
Risk-Free Bets
These are the most common bonus offers you’ll find. They’ll also be called No Sweat Bets, Second Chance Bets, First Bet Insurance, Bonus Bets, First Bets, etc. Always make sure you check the details of the promotion you’re using to make sure it’s a Risk-Free Bet, and what the terms and details of the offer are. The four offers from the sites above for Maryland all fall under the category of risk-free bets.
The concept of this offer is simple: you open an account, deposit some money, and make a bet. The very first bet (MAKE SURE YOU GET THIS RIGHT) will be your risk-free bet. If you win that first bet, cool, you get the winnings from that bet and can withdraw it. If you lose your first bet, the risk-free bet kicks in, and you get a free bet deposited into your account equal to the amount of your first bet. So you basically get a do-over if you lose the first one.
Now you won’t be able to just withdraw the free bet in cash if you lose and get your money back. That would be too easy. The risk-free bet is a bet, you can only use it to bet on another game. If you win that second wager, you can withdraw your winnings. But if you don’t, you can still win by hedging your bets on a different sportsbook. That’s what I’m going to show you.
To find which games to bet on and how much to bet, you’ll need to use a different free website. Go to Crazy Ninja Odds.
Go to Settings in the top right corner, uncheck the sites you aren’t using.
Now go back to Home. Click on Risk-free bet page.
Now we need to choose an offer to convert. Let’s choose our Caesars $1,000 First Bet. We can walk through the steps first, to see which game we want to bet and how much we need to deposit.
First, starting at the top, under “Reward” we’ll enter 100%. With this offer, if we lose our first bet, we get a free bonus bet of 100% of the amount of our first bet, up to $1,000.
Next, we’ll select “Free bet (70%)”. Our free bonus bet will be convertible at about 70%, but that’s not something we need to understand right now. Just check the box and move on.
Next, open “Risk Free Bet Sportsbook” and select Caesars.
Now the page should be filled out like this.
Click “Update” at the bottom. Scroll down, and you’ll see a chart like this.
If none of this means anything to you, that’s fine. I’ll walk you through exactly what to do.
The bets are sorted by ranking from best to worst value. So we always want to choose the top bets unless we have a reason not to. In this case, we are making our risk-free bet on Caesars, and we want to hedge on the site where we aren’t trying to convert any offers, FanDuel. So we want to look at the second column on the right, Hedge Bet Sportsbook. Go down the column until you find FanDuel. In that row, the third column from the left has a “Calc” button. I’ve highlighted the button here.
Click the button. You’ll get a popup that looks like this.
So this is an NHL hockey game between the Dallas Stars and the Edmonton Oilers. If you know absolutely nothing about hockey, perfect. Neither do I. The important thing is that this shows us which wagers to place, and for how much. The left column is our Risk-Free Bet on Caesars, and the right column is our Hedge on FanDuel.
Our first decision is how much to wager. You’ll see that the Caesars wager is currently set to $100. But remember, our First Bet offer is for up to $1,000. You can wager any amount up to $1,000, but you’ll only get one shot at this offer, so if you wager less than $1,000, you won’t get the full benefit of the offer, and you’ll never be able to go back and use the rest in the future. It’s one shot. So my advice is wager $1,000, there’s no good reason not to. So we’ll change the wager amount to $1,000.
Now you can see that our risk-free bet is Edmonton Oilers -1.5 for $1,000, and our hedge bet is Dallas Stars +1.5 for $1,604.93. If you don’t know what that means, that’s fine. What you need to know is that you’ll need to deposit at least $1,000 into your Caesars account, and at least $1,604.93 into your FanDuel account. When that’s done, you can check the bets on each site to make sure the odds are accurate. They change constantly, so it’s always good to check both sites just before placing a bet.
First, we’ll open up the Caesars app and search for “Edmonton Oilers.” Sure enough, the game pops up.
Then we’ll click on that game and open it up
There are four things we want to check on each bet before placing it. I’ve highlighted them above. We have the Edmonton Oilers -1.5, odds of +196, a wager of $1,000, and a payout of $2,960. If we compare that with the correct column in our Risk-Free Bet Calculator, we’ll see that everything is correct.
Now we want to do the same for the FanDuel hedge. We’ll open the FanDuels app and search for “Dallas Stars” and find the same game against the Oilers.
Here we can see the first problem. The spread we see here is -1.5, odds of +225. Our Risk-Free Bet Calculator is asking for Dallas Stars +1.5, odds -245. So we need to select a different line. Farther down the page you’ll see “Series Alternate Handicap.” Open that, and you’ll see Dallas Stars +1.5.
This is the bet we’re looking for. But you’ll also notice that the odds are -225 instead of -245. So we can select this bet, but we need to go back to our Risk-Free Bet Calculator and change the odds to get the correct amount to bet on this line.
So go back to the calculator and change -245 to -225. You’ll see this.
As you can see, the amount of the wager has changed to $1,564.62. So we can go back to FanDuel, select Dallas Stars +1.5, odds -225, and enter our updated wager amount.
As you can see, when we add the “Wager” and the “To Win” amount, we get $2,260.01. Looking at our calculator, that’s the exact number in our “Payout” row. So these are the bets we need to make.
Now that we’ve double checked everything, we can go back and make our $1,000 bet on Caesars, and immediately go make our $1,564.62 bet on FanDuel.
Awesome!
Now what? Well, our job is done. We just wait to see which team wins. Not that it matters to us either way. But which team wins will determine our next step.
Looking at our calculator again, there are two possible outcomes.
The first outcome is the Edmonton Oilers win. In that case, our Caesars bet will payout $2,960, while our FanDuel bet will be a total loss. Here’s how we do the math on that scenario.
We start with our $2,960 Caesars balance. We subtract our $1,564.62 FanDuel bet (which was a loss). Then we subtract the $1,000 we initially deposited and wagered on Caesars. This leaves us with a profit of $395.38! Not bad for a one day return on $2,564.62, while taking no risk.
Now for the second scenario. That would be if the Dallas Stars win. In that case, our Caesars bet is a total loss. Our FanDuel bet pays our $2,260.01
So to calculate our profit here, we start with our payout of $2,260.01, subtract our wager of $1,564.62, subtract our Caesars wager of $1,000 (which was a loss), and then add 70% of our free bonus Caesars bet of $1,000, or $700 (more on that in a minute). Once again, that gives us a profit of $395.39.
Now back to the free bonus bet. Since our Caesars bet lost, we qualified for the promotional payout. If we check the Caesars app, we should see a bonus bet of $1,000 in our balance. Remember I said that you can’t just withdraw the bonus bet? This situation is where that becomes an issue. So we have to place a $1,000 wager with Caesars before we can withdraw that money. The problem with that is, what if our second wager also loses? Then we lose money on the entire process. That’s where the 70% number comes in. We’ll use a similar process when making that $1,000 wager, by hedging on a second site once again. By doing that, we’ll be guaranteed to collect around 70% of the wager, or $700. I’ll explain that in the next section.
Free Bets
This is the name for the bet we get if we lose our initial bet on a site with a Risk-Free Bet offer. This is just what it sounds like, a free bet. You can bet the amount on a game, and if you win, the winnings are your money. You’re free to withdraw that cash.
How do we ensure we still make a profit, even if our free bet loses? Well, Crazy Ninja Odds can help once again. Go back to their homepage, and this time click on Free Bets instead of Risk Free Bets. This time all we need to do is enter the sportsbook, Caesars, and click “update.” We’ll get a chart like this.
You know the drill by now. We find the first option on our Hedge Bet Sportsbook, FanDuel. This time it’s highlighted on the second row. Click “Calc.”
This is a money line bet, so it’s slightly different than the first one, but you won’t have any trouble figuring it out this time. You can check Caesars, and you’ll find the money line bet of $1,000 on the Pacers at +222, with a payout of $2,220.
Make sure you select your free bonus bet when you make the wager. If you lost your initial $1,000 deposit and didn’t deposit again, that should be your only option. It will look slightly different than this, since when you use a free bet, your payout won’t include the initial $1,000 wager, so it will read $2,220 instead of $3,220. I don’t have the free offer in my account so I can’t show you the exact screenshot, but you’ll be able to figure it out.
Then jump over to the other side of the game on FanDuel.
You’ll notice that the line is -275 instead of -270 like your calculator said. By now you know how to go back and change the odds in the calculator to get this.
Once again, you’ll want to make a $1,628 wager on the Boston Celtics at -275 to hedge your $1,000 free bonus bet on the Indiana Pacers at +222.
I could go through the math again, but you know how to do it now. You can look at the profit line and see that both outcomes will pay $592. If you remember, our initial bet used 70% of $1,000, or $700, as a bonus bet profit target. So given the odds available on this particular day, you’ll end up with just over $100 less profit if you need to convert the bonus bet than you’ll make if your first Caesars bet wins. That’s unfortunate, but just a result of games and odds available on a particular day. Getting a higher conversion rate would require more complex strategies, and this guide is long enough already.
Next Steps
Once you’ve successfully completed your initial offer, you can continue to do the same process for each additional sportsbook available in your state. And as you work through the offers on one site, you can then use that site to hedge the next site you sign up for.
There are a few things to keep in mind. Your free bonus bets are usually time limited. That means if your first bet loses, you often have as little as 7 days to use the free bonus bet before it disappears. So make sure you stay on top of your offers and play them before they expire. If you aren’t sure whether you qualify for a specific promotional offer, reach out to customer support before placing any bets. They’ll be able to explain exactly which offers you qualify for and how to access them.
Once you sign up and start betting, you’ll likely start getting more offers in the apps. They might be free bets, in which case you already know how to play them. But there are other offers as well, some of which you can do in a risk free way. If this guide gets enough interest, I may write more about how to handle other types of offers.
These offers will be available once to each person. So you can play them once, and that’s it. But you can also help each member of your family or close friends sign up and show them how to play the offers, or do it for them. Just be careful with your money management, since there will be a significant capital investment up front. If you’re putting up the capital, make sure it’s someone you fully trust with control of that money.
If there’s enough interest, I may also put together a guide on how you can do this with family members or friends who live anywhere, even if they’re not in a state with legal sports betting.
Most of all, be safe, don’t tie up capital you need for your daily life, and make sure you understand each offer and how to exploit it before placing any wagers.
If you have any questions, feel free to reach out to me and I’ll do my best to help you in any way I can.
Best of luck!

2025-05-21 01:56:38The credit/debt fiat money system is broken. If you haven’t been living under a rock, I’m sure you’re aware that something is really messed up in the financial system. Hopefully you’re at least somewhat aware of the reasons why and are placing blame squarely on the structure of the monetary system and not on politics or “capitalism” or “socialism” or corporations or billionaires or any of the other red herrings the bankers desperately hope to distract you with.
If you’re still obsessing over any of those things, that’s okay too, and you’re the reason I started this newsletter. It’s impossible to make good decisions without understanding the relevant information, and when it comes to money, almost no one understands the relevant information. My goal is to change that for as many people as I can reach, to grow the small group of people who are knowledgeable and empowered to make better decisions on money and finance.
Previous articles have been focused on economic theory and how money works at a conceptual level. That’s critically important to understand, and if you haven’t taken the time to read those articles, I know it will open your eyes to the world in a way you’ve never considered before. That understanding will give you a huge advantage in benefiting from what I’m about to describe. But today’s subject is strictly practical, actionable information on one specific financial instrument, and how you can use it to game the broken money system to benefit YOU.
Money Is Not Scarce
If you read my previous articles, you’ll understand that one of the biggest problems with the credit/debt money system is that money is not scarce in this system. In fact, the quantity of money is basically unlimited. That’s because money is created by banks every time they make a loan. Unlike everything you’ve ever thought, banks don’t lend out money that’s given to them by depositors. They create new money, out of thin air, with a computer keystroke, every time they make a new loan. That means in practical terms that the amount of money is only limited by the willingness of banks to make loans. And since banks profit by charging interest to loan out money they can create at zero cost, they’re incentivized to make a LOT of loans.
Now as you can easily see, things that aren’t scarce don’t have a lot of value. The less scarce and more easily available something is, the less valuable it becomes. If you and a friend were standing on the shore of Lake Michigan and you reached down and scooped up a cup full of water, turned to your friend, and said “I’ll trade you this cup of water for your Rolex watch,” he’d look at you like you lost your mind. And rightly so, since a cup of water on the shore of a giant lake is so abundant and easily accessible that it has no value compared to a Rolex watch, which are deliberately produced in very limited amounts to increase their scarcity and value.
The difference between money and the water in that example is that money is not scarce, but it is selectively scarce. If you’re a bank, you have access to as much money as you choose to loan out, at zero cost. On the other hand, if you aren’t a bank, money is only available if the bank decides to create some and loan it to you, or you work hard to earn money someone else already has.
This selective scarcity of money is the root cause of the massive wealth inequality we see today. Money is essential to survive in the modern economy, but access to that money is very unevenly distributed.
So how does this benefit certain people? You might be thinking, but don’t borrowers have to pay the loan back with interest? Of course it’s easy to see how the banks benefit, but plenty of wealthy people are not bankers. And that’s a good point. Here’s how.
Because of the incentives banks have to make loans, the amount of money in circulation tends to keep rising exponentially. The amount of most real goods in the economy, however, typically doesn’t rise as fast. When you have more money circulating in the economy without more goods available, the prices people are willing to pay for those goods will go up. That means prices of some scarce goods rise very consistently over time. Those with access to newly created money in the form of loans benefit by using that money to buy assets that are more scarce than the money they borrowed to buy the asset. So they may buy an asset for $1 million, but by the time the loan is due to be repaid, the continuous inflation caused by the increasing money supply might have pushed the price of that asset up to $1.5 million. So subtract the interest paid from $500,000, and there’s your profit, all for doing nothing but convincing a banker to create some money and let you borrow it. The concept that those closest to the source of new money will benefit the most, because they can buy things before the prices rise, is called the Cantillon effect.
Benefitting from the Cantillon Effect
So how can you benefit? You can see that borrowing a bunch of money and buying a good asset with it would be the perfect way to take advantage of the Cantillon effect. But the problem for most people is, if they go to the bank and ask to borrow a few hundred thousand dollars, they’ll be declined in a millisecond. If you’re not already wealthy, you’re going to have a really tough time getting a big loan at a low interest rate, which is what it takes to make this system work in your favor. Most people only have access to loans in the form of a credit card or personal loan, which will be for a small amount and a very high interest rate. That’s not helpful. Luckily there’s one exception, one way almost anyone can borrow a big chunk of money at a low interest rate, and buy an asset that will increase in price over time as the money supply grows: a mortgage.
If you have the income and credit to support a mortgage payment, it can be a great way to take advantage of the broken monetary system to accumulate some long term wealth. However, there are a few caveats and some simple tricks that can make all the difference.
First, while the constant demand for houses fueled by easy access to newly created money means house prices tend to rise consistently over time, there are no guarantees. The housing market often has periods of boom and bust, and falling prices can last for years. Borrowing is always risky, and you shouldn’t take a risk you don’t understand or aren’t comfortable with. While no one can time the housing market, it’s always good to at least be aware that the housing market does rise and fall in cycles, and try to avoid buying when all signs point to housing being extremely overpriced.
Second, just because houses are rising in price doesn’t mean they’re rising in value. It’s a simple concept, but one most people miss. Like Warren Buffet says, price is what you pay, value is what you get. If you buy a house today for $400,000, and in 10 years that same house sells for $700,000, how much did the value of the house change? The price went up, but the house is still the same house in the same location, it’s just a decade older. And a decade of wear and tear is a decrease in value, not an increase. Think of it this way. You can sell for $700,000 and you have $300,000 of “profit”. But if you want the same house back, you can’t buy it for $400,000 again and pocket the $300,000. You can only get the same house back for the full price you received. You haven’t increased your purchasing power at all in terms of housing with that “profit”. Your house hasn’t become more valuable, your money has just become less valuable when measured against houses. In that sense, you probably can’t increase your purchasing power by buying a house to live in, but you can at least avoid losing purchasing power. If you just save money in the bank to buy a house later, house prices will probably rise faster than you can save. That’s especially true if you’re paying rent at the same time. At least with a mortgage, if you pay long enough you own a house eventually. You can pay rent your whole life and you’ll still own nothing at the end.
Understanding Amortization
The key to making a mortgage work for you is to understand and manipulate the amount of principal and interest you pay over the term of the loan. To do this, you need to understand how a mortgage amortization schedule works. An amortization schedule is basically a big chart of your mortgage payments each month, showing how much of each payment is applied to paying down the principal and how much is paying interest. The payment size is the same each month, but the amount of principal and interest varies over the term of the loan, and that’s key to understanding how to manipulate the system.
To understand amortization, you need a good amortization calculator. There are plenty of different ones available online, but I’m going to use the one here to illustrate. In this example, I’m going to arbitrarily choose a mortgage size of $500,000 and an interest rate of 7%, but you can of course use your own numbers. When we enter this into the calculator with a loan term of 30 years and click “calculate”, we get something that looks like this.
You can see the monthly payment of $3,326.51, and the total payments over 30 years of almost $1.2 million, almost $700,000 of which is interest. So you end up paying more in interest than the total amount of principal you borrowed. Gulp.
That seems terrible, and it is. But this is where understanding the amortization schedule, that scary looking chart to the left, is going to pay big dividends. First, change the amortization schedule from an annual schedule to a monthly schedule. You’ll see something that looks like this.
So now for each month, you can see how much of the payment is interest, how much is principal, and how much of your original $500,000 balance is still outstanding. As you can see in month one, you’re paying over $2,900 in interest and only $400 in principal, leaving you with a balance of $499,590.15. The reason the interest is so high initially is that you have to pay interest on the full principal balance. As the principal gets paid down, you are now paying interest on a smaller balance. If you scroll down to year 29, you’ll see the opposite situation. In month 338 you’ll pay $2,900 of principal and only $400 of interest. That’s because you’re now paying interest on a balance of only $68,000 instead of $500,000.
As you can see, getting into the later years of the mortgage is a much better situation than paying huge amounts of interest in the first few years. Is there a way to get closer to the end fast? Yes there is, and you may be surprised how easy it is.
Go back to the annual amortization schedule. Suppose you want to take 5 years off your mortgage. How much would it cost to do, and how much would you save in interest? There are two ways to do this, and we’ll cover both.
First, the easiest way to get 5 years off your mortgage is to move straight down the amortization schedule to year 6. How can you do that? Look at the annual amortization schedule for year 5. Your ending balance is a little over $470,000. That means to get to that point in the loan repayment schedule, you need to pay $30,000 of principal. So let’s see where a lump sum payment of $30,000 gets us. Inside the box where you entered your loan terms you’ll see a little checkbox labeled “Optional: make extra payments”. Click that box. In the “Extra one-time pay” box, enter $30,000. Click calculate. You’ll see this.
And viola, with the extra payment, the loan will be paid off in 25 years, and you’ll save $172,362 in interest. Pretty amazing results for a one-time $30,000 payment.
Of course for the sake of simplicity, that’s assuming you pay the $30,000 at the very beginning of the loan. Paying the lump sum later into the loan term will change the exact amount of the savings. You can play around with other payment sizes, or even multiple lump sum payments, and see how much each one will save.
But most of you will be thinking, “Where am I going to get $30,000? That’s never going to happen.” If that’s you, don’t worry. We can do the exact same thing a different way.
Go back to your calculator, remove the lump sum payment, and leave everything else the same, except the loan term. Change the loan term to 25 years instead of 30 years. Click calculate. Now look at just one number, the payment size. You’ll see it’s $3,533.90. Don’t worry about anything else, just note that number. Now reset to your original calculation of a 30 year term. You’ll see the payment size is back down to $3,326.51. Now get out your calculator and subtract $3,326.51 from $3,533.90. You’ll get $207.39. Go back to your “make extra payments” box and enter an “extra monthly pay” of $207.39. Click calculate.
As you can see, just by paying an extra $207 of principal every month, you’ll pay the loan off 5 years faster and save $137,379 in interest.
You’ll save a little less that way than the lump sum payment, because you’re not paying the principal down as much early in the loan. But paying an extra $200 a month is much easier for most people than accumulating thousands of dollars to make a large lump sum payment. A few hundred dollars is only about 6% of the size of this mortgage payment, so it’s really a small difference. And if you can’t afford to pay a few percent of your payment size extra each month, the mortgage is probably bigger than you can reasonably afford.
You can play around with these numbers in all kinds of ways. It’s a good way to help you think about your financial decisions, and the real impact they might have over time. Say for example, you’re considering buying a new grill for the backyard. You only grill a few times a month during the summer, and a replacement model of the basic charcoal grill you have now would be perfectly serviceable. It’s available for $119 on Amazon. But your brother-in-law just bought one of those Big Green Eggs and he keeps bragging about how amazing it is. They’re $1,950, but you can afford it, you just got a nice little bonus at work. So why not?
But before you get out the checkbook, let’s take a quick look at the mortgage calculator. Let’s see how much that extra $1,831 spent on a grill you don’t really need will actually cost you. Again, input your mortgage size, term, and interest rate, and add an extra one-time payment of $1,831.
Hopefully you’re still using that Big Green Egg in 30 years, because by that time, it will have cost you almost $13,000 in additional interest payments.
You can fill in the blank with your own discretionary purchases and see whether they’re really worth the cost. It’s just another little tool to help plan your financial decisions. It’s free to do, and can make a very significant difference in your financial well-being down the road. But almost no one takes advantage of the opportunity, so you’ll have a huge leg up on most people just by knowing this simple concept.
The Bottom Line
To take advantage of the opportunity to build wealth with a mortgage, there are only two simple rules.
-
Use a mortgage to buy a reasonably priced house that you couldn’t otherwise afford.
-
Take advantage of amortization to pay that mortgage off as fast as possible, so you pay as little interest as possible while still capturing the increase in price of the house.
If you already own a home, you can use the same concept. Take out a mortgage for whatever amount you’re comfortable with, and use the money to buy an asset that will increase in price with inflation. Choose your asset wisely, and don’t take on more debt than you can afford. But if you make good decisions, you can take advantage of the broken financial system, using this little mortgage cheat code to get the Cantillon effect on your side. The wealthy are doing it every day, so don’t miss the opportunity to lock in long-term, fixed rate debt and acquire hard assets. As the debt/credit fiat system implodes, the opportunity to do this will disappear. Take advantage of it while you can.

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