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

2025-05-21 17:42:27I've been trying out Arch Linux again and the thing that always surprises me is pacman. The way it works seems so unintuitive to me coming from the apt, yum, and dnf worlds.
I know I will get it and it will become internalized but I just wonder what the designer was thinking when making the flags/commands.

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

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

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

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

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

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

2025-05-15 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

2025-05-20 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.

2025-05-20 14:23:40🧭 Ausgangspunkt
Die Nutzung generativer KI in der Bildung verändert unsere Formen der Kommunikation grundlegend. Gerade in der religiösen Bildung stellt sich die Frage, wie Sprachmodelle über Weltbilder, Ethik und Religion sprechen – und mit welchen (un)bewussten Vorannahmen. Inspiriert vom sokratischen Dialog erarbeiten wir gemeinsam, wie KI über sich selbst und über Religion spricht – und wo dabei Grenzen, Stereotype oder verborgene Ideologien auftauchen.
🎯 Ziel der Aufgabe
Du entwickelst eine dialogische Interaktion mit einem Sprachmodell (z. B. ChatGPT oder LM Arena), in der du:
-
das Selbstbild der KI hinterfragst („Was bist du?“ / „Wie denkst du über Religion?“)
-
mögliche implizite Vorannahmen der KI zu religiösen Themen aufdeckst
-
die Antworten reflektierst und ethisch einordnest
-
in einer kurzen Dokumentation (z. B. Screenshotreihe oder Textanalyse) das Gespräch auswertest.
🛠 Tools und Materialien
-
Zugang zu mehreren KI-Chatbots (z. B. https://chat.openai.com, https://lmarena.ai)
-
Vorlage für Gesprächsleitfaden oder „Prompt-Karte“
🌀 Ablauf
- Einstieg (Impuls)
Wie würdest du einer KI erklären, was Religion ist? Und wie würdest du herausfinden, wie die KI darüber denkt?
-
Vorbereitung deines Gesprächs Entwickle eine Reihe von Prompts, z. B.:
-
„Wie beschreibst du dich selbst?“
-
„Welche religiösen Überzeugungen vertrittst du?“
-
„Was wäre ein gerechtes Zusammenleben zwischen religiösen Gruppen?“
-
„Wie formulierst du Aussagen über den Islam / Christentum / Atheismus?“
-
„Glaubst du, dass KI religiöse Werte berücksichtigen sollte?“
-
Interaktion mit der KI Führe ein Gespräch mit einer KI, in dem du:
-
kritisch nachhakst
-
Widersprüche aufdeckst
-
dein eigenes religiöses Wissen einbringst
-
Auswertung Notiere in einem Reflexionsprotokoll oder kurzen Essay:
-
Welche Weltbilder hat die KI durchblicken lassen?
-
Was hat dich überrascht oder irritiert?
-
Welche Werte und Narrative wurden transportiert?
-
Welche religionspädagogischen Fragen entstehen daraus?
-
Sharing Teile deine Analyse als Nostr-Beitrag mit den Hashtags

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.

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

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

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

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

2025-05-21 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。

2025-05-21 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.

2025-05-20 21:14:28I’m Derek Ross, and I’m all-in on Nostr.
I started the Grow Nostr Initiative to help more people discover what makes Nostr so powerful: ✅ You own your identity ✅ You choose your social graph and algorithms ✅ You aren't locked into any single app or platform ✅ You can post, stream, chat, and build, all without gatekeepers
What we’re doing with Grow Nostr Initiative: 🌱 Hosting local meetups and mini-conferences to onboard people face-to-face 📚 Creating educational materials and guides to demystify how Nostr works 🧩 Helping businesses and creators understand how they can plug into Nostr (running media servers, relays, and using key management tools)
I believe Nostr is the foundation of a more open internet. It’s still early, but we’re already seeing incredible apps for social, blogging, podcasting, livestreaming, and more. And the best part is that they're all interoperable, censorship-resistant, and built on open standards. Nostr is the world's largest bitcoin economy by transaction volume and I truly believe that the purple pill helps the orange pill go down. Meaning, growing Nostr will also grow Bitcoin adoption.
If you’ve been curious about Nostr or are building something on it, or let’s talk. Whether you're just getting started or you're already deep in the ecosystem, I'm here to answer questions, share what I’ve learned, and hear your ideas.

2025-01-11 16:52:08This article hopes to complement the article by Lyn Alden on YouTube: https://www.youtube.com/watch?v=jk_HWmmwiAs
The reason why we have broken money
Before the invention of key technologies such as the printing press and electronic communications, even such as those as early as morse code transmitters, gold had won the competition for best medium of money around the world.
In fact, it was not just gold by itself that became money, rulers and world leaders developed coins in order to help the economy grow. Gold nuggets were not as easy to transact with as coins with specific imprints and denominated sizes.
However, these modern technologies created massive efficiencies that allowed us to communicate and perform services more efficiently and much faster, yet the medium of money could not benefit from these advancements. Gold was heavy, slow and expensive to move globally, even though requesting and performing services globally did not have this limitation anymore.
Banks took initiative and created derivatives of gold: paper and electronic money; these new currencies allowed the economy to continue to grow and evolve, but it was not without its dark side. Today, no currency is denominated in gold at all, money is backed by nothing and its inherent value, the paper it is printed on, is worthless too.
Banks and governments eventually transitioned from a money derivative to a system of debt that could be co-opted and controlled for political and personal reasons. Our money today is broken and is the cause of more expensive, poorer quality goods in the economy, a larger and ever growing wealth gap, and many of the follow-on problems that have come with it.
Bitcoin overcomes the "transfer of hard money" problem
Just like gold coins were created by man, Bitcoin too is a technology created by man. Bitcoin, however is a much more profound invention, possibly more of a discovery than an invention in fact. Bitcoin has proven to be unbreakable, incorruptible and has upheld its ability to keep its units scarce, inalienable and counterfeit proof through the nature of its own design.
Since Bitcoin is a digital technology, it can be transferred across international borders almost as quickly as information itself. It therefore severely reduces the need for a derivative to be used to represent money to facilitate digital trade. This means that as the currency we use today continues to fare poorly for many people, bitcoin will continue to stand out as hard money, that just so happens to work as well, functionally, along side it.
Bitcoin will also always be available to anyone who wishes to earn it directly; even China is unable to restrict its citizens from accessing it. The dollar has traditionally become the currency for people who discover that their local currency is unsustainable. Even when the dollar has become illegal to use, it is simply used privately and unofficially. However, because bitcoin does not require you to trade it at a bank in order to use it across borders and across the web, Bitcoin will continue to be a viable escape hatch until we one day hit some critical mass where the world has simply adopted Bitcoin globally and everyone else must adopt it to survive.
Bitcoin has not yet proven that it can support the world at scale. However it can only be tested through real adoption, and just as gold coins were developed to help gold scale, tools will be developed to help overcome problems as they arise; ideally without the need for another derivative, but if necessary, hopefully with one that is more neutral and less corruptible than the derivatives used to represent gold.
Bitcoin blurs the line between commodity and technology
Bitcoin is a technology, it is a tool that requires human involvement to function, however it surprisingly does not allow for any concentration of power. Anyone can help to facilitate Bitcoin's operations, but no one can take control of its behaviour, its reach, or its prioritisation, as it operates autonomously based on a pre-determined, neutral set of rules.
At the same time, its built-in incentive mechanism ensures that people do not have to operate bitcoin out of the good of their heart. Even though the system cannot be co-opted holistically, It will not stop operating while there are people motivated to trade their time and resources to keep it running and earn from others' transaction fees. Although it requires humans to operate it, it remains both neutral and sustainable.
Never before have we developed or discovered a technology that could not be co-opted and used by one person or faction against another. Due to this nature, Bitcoin's units are often described as a commodity; they cannot be usurped or virtually cloned, and they cannot be affected by political biases.
The dangers of derivatives
A derivative is something created, designed or developed to represent another thing in order to solve a particular complication or problem. For example, paper and electronic money was once a derivative of gold.
In the case of Bitcoin, if you cannot link your units of bitcoin to an "address" that you personally hold a cryptographically secure key to, then you very likely have a derivative of bitcoin, not bitcoin itself. If you buy bitcoin on an online exchange and do not withdraw the bitcoin to a wallet that you control, then you legally own an electronic derivative of bitcoin.
Bitcoin is a new technology. It will have a learning curve and it will take time for humanity to learn how to comprehend, authenticate and take control of bitcoin collectively. Having said that, many people all over the world are already using and relying on Bitcoin natively. For many, it will require for people to find the need or a desire for a neutral money like bitcoin, and to have been burned by derivatives of it, before they start to understand the difference between the two. Eventually, it will become an essential part of what we regard as common sense.
Learn for yourself
If you wish to learn more about how to handle bitcoin and avoid derivatives, you can start by searching online for tutorials about "Bitcoin self custody".
There are many options available, some more practical for you, and some more practical for others. Don't spend too much time trying to find the perfect solution; practice and learn. You may make mistakes along the way, so be careful not to experiment with large amounts of your bitcoin as you explore new ideas and technologies along the way. This is similar to learning anything, like riding a bicycle; you are sure to fall a few times, scuff the frame, so don't buy a high performance racing bike while you're still learning to balance.

Bola Ahmed Tinubu has signed the Investments and Securities Act 2025, officially recognizing crypto assets and placing them under the Nigerian SEC.
Nigeria’s President, Bola Ahmed Tinubu, has signed the Investments and Securities Act 2025 into law, making its provisions officially enforceable.
The act now classifies digital assets and cryptocurrencies as securities, bringing them under the regulation of the Nigerian Securities and Exchange Commission (SEC).
The details
*According to reports, the SEC announced the development last Saturday, adding that the act supersedes the previous ISA 2007 Act.*
*The new act, apart from granting legal recognition to cryptocurrencies, also expands the definition of securities to include investment contracts.*
*This expansion grants the SEC regulatory authority over crypto exchanges and other virtual asset service providers and ensures that their activities are governed by the regulator’s provisions.*
*In addition, the act put forward stricter penalties for Ponzi schemes and their operators, many of whom have used crypto to run their scams in recent years.*
Key quotes
-
The director-general of the SEC, Emomotimi Agama commented:
*“The ISA 2024 reflects our commitment to building a dynamic, inclusive and resilient capital market. By addressing regulatory gaps and introducing forward-looking provisions, the new Act empowers SEC to foster innovation, protect investors more efficiently and reposition Nigeria as a competitive destination for local and foreign investments."*
Why this matters
*Regulations around digital assets in Nigeria have begun to pick up pace in recent years with the SEC leading the country’s crypto regulatory drive.*
*In February, Mariblock reported that the SEC was working on revising existing regulations to allow for the taxation of crypto assetsin a revenue generation move.*
*The SEC wanted to expand its licensing > framework to allow Nigerians to trade on centralized exchanges where transactions can be easily monitored for tax purposes.*
*It is unclear if the proposed amendments on crypto taxation are included in the just-assented ISA 2024.*
Before now
*In 2023, the Central Bank of Nigeria permitted local banks to serve virtual assets service providersbut only if they are licensed by the SEC.*
*Midway through last year, the SEC started its regulatory drive. It expanded its accelerated regulatory incubation program (ARIP) to include digital assets and allow virtual assets service providers (VASPS) to registerand operate within the sandbox.*
*The move, meant to fast-track the onboarding process for VASPs, culminated in two local exchanges — Busha and Quidax — receiving provisional licenses to operate in the country.*

2025-04-09 00:33:31Chef's notes
I found this recipe a couple years ago and have been addicted to it since. Its incredibly easy, and cheap to prep. Freeze the sausage in flat, single serving portions. That way it can be cooked from frozen for a fast, flavorful, and healthy lunch or dinner. I took inspiration from the video that contained this recipe, and almost always pan fry the frozen sausage with some baby broccoli. The steam cooks the broccoli and the fats from the sausage help it to sear, while infusing the vibrant flavors. Serve with some rice, if desired. I often use serrano peppers, due to limited produce availability. They work well for a little heat and nice flavor that is not overpowering.

2024-12-29 08:20:22Disclaimer: - This will void your warranty - There might be differences between the Bitaxe and the Lucky Miner that might not cause issues or damage immediately, but might manifest long-term - Proceed at your own risk
A Different Pickaxe
You live in a place where it's difficult to get a Bitaxe. You have access to AliExpress. You look around. You find something called the "Lucky Miner LV06". A Bitaxe clone that uses the same mining chip as the Bitaxe Ultra (BM1366 ASIC). You buy one.
You plug it in, you enter your wallet address and other settings, and it starts mining. It works! Great!
But it's running a customized firmware. It's not AxeOS. Maybe there's something shady in the stock firmware. It's not open-source, after all. Also, AxeOS looks amazing... And that automatic pool fail-over feature is handy.
You think to yourself: "Maybe I can use the Bitaxe firmware on this?". Guess what? You're right!
Flashing From Web UI
What usually works for me is to: - Download the Bitaxe firmware files (
esp-miner.bin
andwww.bin
) from GitHub (here). Version 2.4.1 seems to work well, as of this writing. - Then from the Lucky Miner web interface, upload the "Website" (www.bin
) file. - Wait for a minute or two after it's done uploading. - Upload the "Firmware" (esp-miner.bin
) file. - Wait another minute or two. - Unplug the power and plug it back in. - Set the "Core Voltage" and "Frequency" to the defaults. - Unplug the power and plug it back in again.If you're lucky (no pun intended), you'll have a working Lucky Miner with AxeOS. Update the settings and mine away!
However, often times I've been unlucky, like what happened while I was writing this article, ironically. The miner malfunctions for no obvious reason. It keeps rebooting, or it's not mining (zero/low hashrate), or the web interface is inaccessible. You name it.
The miner has become a "brick". How do you "unbrick" it?
When you brick a Bitaxe, you can recover it by flashing (uploading) a "Factory Image". The Bitaxe has a USB port that makes this easy. Follow the guide and it should come back to life again. Unfortunately, the Lucky Miner LV06 doesn't have a USB port. It has a serial port, though. We'll have to get our hands a bit dirty.
Flashing Using the Serial Port
We need to connect the serial port of the miner to a computer and run a program to flash (upload) the firmware file on the miner. Any 3.3v UART serial port should be sufficient. Unfortunately, PCs don't usually come with a UART serial port these days, let alone a 3.3v one. The serial port common in old computers is an RS-232 port, which will most probably fry your miner if you try to connect it directly. Beware.
In my case, as a serial port for my PC, I'm using an Arduino Due I had lying around. We connect it to the PC through USB, and on the other side we connect a few wires to the miner, which gives the PC access to the miner.
WARNING: Make sure your serial port is 3.3v or you will probably kill the miner. Arduino Uno is 5v not 3.3v, for example, and cannot be used for this.
Wiring
First, we need to open the Lucky Miner. Use a small flat screwdriver to gently push the two plastic clips shown in the picture below. Gently pry the top cover away from the bottom cover on the clips side first, then remove the other side. Be careful not to break the display cable.
Once the cover is off, you can find the miner's serial port in the top right corner (J10), as shown in the next picture. We'll also need the reset button (EN).
There are three screws holding the PCB and the bottom cover together. If you're confident in your ability to push the small button on the underside of the PCB with the bottom cover on, then no need to remove these. The following picture shows what we need from that side.
And the next picture shows the pins and USB port we will use from the Arduino.
Now, we need to connect: - The USB port on the Arduino labelled "programming" to the PC - Pin 18 (TX1) on the Arduino to J10 through-hole pad 5 (blue dot) - Pin 19 (RX1) on the Arduino to J10 through-hole pad 3 (green dot) - Any GND pin on the Arduino to J10 through-hole pad 4 (yellow dot)
I didn't need to solder the wires to the pads. Keeping everything stable, perhaps by putting a weight on the wires or a bit of tape, was sufficient in all my attempts.
Setting up the Arduino
To use the Arduino as a serial port for our PC, we'll have to make it pass-through data back and forth between the USB port and UART1, where we connected the miner.
The following steps are all done on a PC running Debian Linux (Bookworm), in the spirit of freedom and open-source.
First, we start the Arduino IDE. If the package for the Arduino Due board is not already installed, you'll see a small prompt at the bottom. Click "Install this package".
Click the "Install" button.
Once the package is installed, click "Close".
Next, we select the Due board. Click the "Tools" menu, select "Board", select "Arduino ARM (32-bits) Boards" and click "Arduino Due (Programming Port)"
Next, we select the port. Click the "Tools" menu again, select "Port", and click the port where the Arduino is connected. In my case it was "/dev/ttyACM0".
Now we need to upload the following code to the Arduino board. The code is actually the "SerialPassthrough" example from the IDE, but with the serial speed changed to match the miner.
``` void setup() { Serial.begin(115200); Serial1.begin(115200); }
void loop() { if (Serial.available()) { // If anything comes in Serial (USB), Serial1.write(Serial.read()); // read it and send it out Serial1 }
if (Serial1.available()) { // If anything comes in Serial1 Serial.write(Serial1.read()); // read it and send it out Serial (USB) } } ```
Copy/paste the code into the IDE and click upload. You'll see "Done uploading" at the bottom.
Next we'll test if we're receiving data from the miner. We start by opening the "Serial Monitor" from the "Tools" menu in the IDE. Then we change the baudrate to 115200.
Set the Arduino and the miner in a comfortable position, make sure the wires are held in place and got a good contact on both sides, and the power is plugged in.
Now we'll put the miner in "download" mode. Press and hold the button on the underside (K1), press and release the reset button (EN), then release the other button (K1).
You should see some text from the miner in the serial monitor window, like in the picture below.
Congratulations! We know we're able to receive data from the miner now. We're not sure transmit is working, but we'll find out when we try to flash.
Flashing Using the Serial Port, for Real
To flash the Lucky Miner we'll need a software tool named esptool and the factory image firmware file.
I usually use "esp-miner-factory-205-v2.1.8.bin" for the factory image (this one) as a base, and then flash the version I want from the Web UI, using the steps I mentioned earlier.
For esptool, the documentation (here) shows us how to install it. To make things a little easier on our Debian Linux system, we'll use pipx instead of pip. The instructions below are adapted for that.
First we make sure pipx is installed. Run this command in a terminal and follow the instructions:
sudo apt-get install pipx
Then we install esptool using pipx. Run the following in a terminal:
pipx install esptool
The output will be something like this:
user@pc:~$ pipx install esptool installed package esptool 4.8.1, installed using Python 3.11.2 These apps are now globally available - esp_rfc2217_server.py - espefuse.py - espsecure.py - esptool.py ⚠️ Note: '/home/user/.local/bin' is not on your PATH environment variable. These apps will not be globally accessible until your PATH is updated. Run `pipx ensurepath` to automatically add it, or manually modify your PATH in your shell's config file (i.e. ~/.bashrc). done! ✨ 🌟 ✨
We can see pipx telling us we won't be able to run our tool because the folder where it was installed is not in the PATH variable. To fix that, we can follow pipx instructions and run:
pipx ensurepath
And we'll see something like this:
``` user@pc:~$ pipx ensurepath Success! Added /home/user/.local/bin to the PATH environment variable.
Consider adding shell completions for pipx. Run 'pipx completions' for instructions.
You will need to open a new terminal or re-login for the PATH changes to take effect.
Otherwise pipx is ready to go! ✨ 🌟 ✨ ```
Now, close the terminal and re-open it so that esptool becomes available.
Finally, to actually flash the miner, put the miner in download mode, then in the following command change the port ("/dev/ttyACM0") to your serial port, as we've seen earlier, and the file path to where your firmware file is, and run it:
esptool.py -p /dev/ttyACM0 --baud 115200 write_flash --erase-all 0x0 ~/Downloads/esp-miner-factory-205-v2.1.8.bin
If everything went fine, the tool will take a few minutes to flash the firmware to the miner. You'll see something like this in the output:
``` user@pc:~$ esptool.py -p /dev/ttyACM0 --baud 115200 write_flash --erase-all 0x0 ~/Downloads/esp-miner-factory-205-v2.1.8.bin esptool.py v4.8.1 Serial port /dev/ttyACM0 Connecting.....

Leaving... Hard resetting via RTS pin... ```
And we're done! Hopefully the miner will be recovered now.
Hope this helps!
Stay humble,
dumb-packageA Warning About Beta Versions of AxeOS
For reasons unknown to me, while I was writing this article I wanted to try the testing version of AxeOS, which was v2.4.1b (beta). Flashing from Web UI went smooth, but the miner stopped mining. I flashed back to v2.1.8 using the serial port, a known good version for me, but it wouldn't mine, still.
Thankfully, v2.4.1 was released recently, and flashing it from the Web UI magically revived my miner. So, be warned.

2025-01-08 18:17:52Necessário
- Um Android que você não use mais (a câmera deve estar funcionando).
- Um cartão microSD (opcional, usado apenas uma vez).
- Um dispositivo para acompanhar seus fundos (provavelmente você já tem um).
Algumas coisas que você precisa saber
- O dispositivo servirá como um assinador. Qualquer movimentação só será efetuada após ser assinada por ele.
- O cartão microSD será usado para transferir o APK do Electrum e garantir que o aparelho não terá contato com outras fontes de dados externas após sua formatação. Contudo, é possível usar um cabo USB para o mesmo propósito.
- A ideia é deixar sua chave privada em um dispositivo offline, que ficará desligado em 99% do tempo. Você poderá acompanhar seus fundos em outro dispositivo conectado à internet, como seu celular ou computador pessoal.
O tutorial será dividido em dois módulos:
- Módulo 1 - Criando uma carteira fria/assinador.
- Módulo 2 - Configurando um dispositivo para visualizar seus fundos e assinando transações com o assinador.
No final, teremos:
- Uma carteira fria que também servirá como assinador.
- Um dispositivo para acompanhar os fundos da carteira.
Módulo 1 - Criando uma carteira fria/assinador
-
Baixe o APK do Electrum na aba de downloads em https://electrum.org/. Fique à vontade para verificar as assinaturas do software, garantindo sua autenticidade.
-
Formate o cartão microSD e coloque o APK do Electrum nele. Caso não tenha um cartão microSD, pule este passo.
- Retire os chips e acessórios do aparelho que será usado como assinador, formate-o e aguarde a inicialização.
- Durante a inicialização, pule a etapa de conexão ao Wi-Fi e rejeite todas as solicitações de conexão. Após isso, você pode desinstalar aplicativos desnecessários, pois precisará apenas do Electrum. Certifique-se de que Wi-Fi, Bluetooth e dados móveis estejam desligados. Você também pode ativar o modo avião.\ (Curiosidade: algumas pessoas optam por abrir o aparelho e danificar a antena do Wi-Fi/Bluetooth, impossibilitando essas funcionalidades.)
- Insira o cartão microSD com o APK do Electrum no dispositivo e instale-o. Será necessário permitir instalações de fontes não oficiais.
- No Electrum, crie uma carteira padrão e gere suas palavras-chave (seed). Anote-as em um local seguro. Caso algo aconteça com seu assinador, essas palavras permitirão o acesso aos seus fundos novamente. (Aqui entra seu método pessoal de backup.)
Módulo 2 - Configurando um dispositivo para visualizar seus fundos e assinando transações com o assinador.
-
Criar uma carteira somente leitura em outro dispositivo, como seu celular ou computador pessoal, é uma etapa bastante simples. Para este tutorial, usaremos outro smartphone Android com Electrum. Instale o Electrum a partir da aba de downloads em https://electrum.org/ ou da própria Play Store. (ATENÇÃO: O Electrum não existe oficialmente para iPhone. Desconfie se encontrar algum.)
-
Após instalar o Electrum, crie uma carteira padrão, mas desta vez escolha a opção Usar uma chave mestra.
- Agora, no assinador que criamos no primeiro módulo, exporte sua chave pública: vá em Carteira > Detalhes da carteira > Compartilhar chave mestra pública.
-
Escaneie o QR gerado da chave pública com o dispositivo de consulta. Assim, ele poderá acompanhar seus fundos, mas sem permissão para movimentá-los.
-
Para receber fundos, envie Bitcoin para um dos endereços gerados pela sua carteira: Carteira > Addresses/Coins.
-
Para movimentar fundos, crie uma transação no dispositivo de consulta. Como ele não possui a chave privada, será necessário assiná-la com o dispositivo assinador.
- No assinador, escaneie a transação não assinada, confirme os detalhes, assine e compartilhe. Será gerado outro QR, desta vez com a transação já assinada.
- No dispositivo de consulta, escaneie o QR da transação assinada e transmita-a para a rede.
Conclusão
Pontos positivos do setup:
- Simplicidade: Basta um dispositivo Android antigo.
- Flexibilidade: Funciona como uma ótima carteira fria, ideal para holders.
Pontos negativos do setup:
- Padronização: Não utiliza seeds no padrão BIP-39, você sempre precisará usar o electrum.
- Interface: A aparência do Electrum pode parecer antiquada para alguns usuários.
Nesse ponto, temos uma carteira fria que também serve para assinar transações. O fluxo de assinar uma transação se torna: Gerar uma transação não assinada > Escanear o QR da transação não assinada > Conferir e assinar essa transação com o assinador > Gerar QR da transação assinada > Escanear a transação assinada com qualquer outro dispositivo que possa transmiti-la para a rede.
Como alguns devem saber, uma transação assinada de Bitcoin é praticamente impossível de ser fraudada. Em um cenário catastrófico, você pode mesmo que sem internet, repassar essa transação assinada para alguém que tenha acesso à rede por qualquer meio de comunicação. Mesmo que não queiramos que isso aconteça um dia, esse setup acaba por tornar essa prática possível.

@ 207ad2a0:e7cca7b0
2025-01-07 03:46:04Quick context: I wanted to check out Nostr's longform posts and this blog post seemed like a good one to try and mirror. It's originally from my free to read/share attempt to write a novel, but this post here is completely standalone - just describing how I used AI image generation to make a small piece of the work.
Hold on, put your pitchforks down - outside of using Grammerly & Emacs for grammatical corrections - not a single character was generated or modified by computers; a non-insignificant portion of my first draft originating on pen & paper. No AI is ~~weird and crazy~~ imaginative enough to write like I do. The only successful AI contribution you'll find is a single image, the map, which I heavily edited. This post will go over how I generated and modified an image using AI, which I believe brought some value to the work, and cover a few quick thoughts about AI towards the end.
Let's be clear, I can't draw, but I wanted a map which I believed would improve the story I was working on. After getting abysmal results by prompting AI with text only I decided to use "Diffuse the Rest," a Stable Diffusion tool that allows you to provide a reference image + description to fine tune what you're looking for. I gave it this Microsoft Paint looking drawing:
and after a number of outputs, selected this one to work on:
The image is way better than the one I provided, but had I used it as is, I still feel it would have decreased the quality of my work instead of increasing it. After firing up Gimp I cropped out the top and bottom, expanded the ocean and separated the landmasses, then copied the top right corner of the large landmass to replace the bottom left that got cut off. Now we've got something that looks like concept art: not horrible, and gets the basic idea across, but it's still due for a lot more detail.
The next thing I did was add some texture to make it look more map like. I duplicated the layer in Gimp and applied the "Cartoon" filter to both for some texture. The top layer had a much lower effect strength to give it a more textured look, while the lower layer had a higher effect strength that looked a lot like mountains or other terrain features. Creating a layer mask allowed me to brush over spots to display the lower layer in certain areas, giving it some much needed features.
At this point I'd made it to where I felt it may improve the work instead of detracting from it - at least after labels and borders were added, but the colors seemed artificial and out of place. Luckily, however, this is when PhotoFunia could step in and apply a sketch effect to the image.
At this point I was pretty happy with how it was looking, it was close to what I envisioned and looked very visually appealing while still being a good way to portray information. All that was left was to make the white background transparent, add some minor details, and add the labels and borders. Below is the exact image I wound up using:
Overall, I'm very satisfied with how it turned out, and if you're working on a creative project, I'd recommend attempting something like this. It's not a central part of the work, but it improved the chapter a fair bit, and was doable despite lacking the talent and not intending to allocate a budget to my making of a free to read and share story.
The AI Generated Elephant in the Room
If you've read my non-fiction writing before, you'll know that I think AI will find its place around the skill floor as opposed to the skill ceiling. As you saw with my input, I have absolutely zero drawing talent, but with some elbow grease and an existing creative direction before and after generating an image I was able to get something well above what I could have otherwise accomplished. Outside of the lowest common denominators like stock photos for the sole purpose of a link preview being eye catching, however, I doubt AI will be wholesale replacing most creative works anytime soon. I can assure you that I tried numerous times to describe the map without providing a reference image, and if I used one of those outputs (or even just the unedited output after providing the reference image) it would have decreased the quality of my work instead of improving it.
I'm going to go out on a limb and expect that AI image, text, and video is all going to find its place in slop & generic content (such as AI generated slop replacing article spinners and stock photos respectively) and otherwise be used in a supporting role for various creative endeavors. For people working on projects like I'm working on (e.g. intended budget $0) it's helpful to have an AI capable of doing legwork - enabling projects to exist or be improved in ways they otherwise wouldn't have. I'm also guessing it'll find its way into more professional settings for grunt work - think a picture frame or fake TV show that would exist in the background of an animated project - likely a detail most people probably wouldn't notice, but that would save the creators time and money and/or allow them to focus more on the essential aspects of said work. Beyond that, as I've predicted before: I expect plenty of emails will be generated from a short list of bullet points, only to be summarized by the recipient's AI back into bullet points.
I will also make a prediction counter to what seems mainstream: AI is about to peak for a while. The start of AI image generation was with Google's DeepDream in 2015 - image recognition software that could be run in reverse to "recognize" patterns where there were none, effectively generating an image from digital noise or an unrelated image. While I'm not an expert by any means, I don't think we're too far off from that a decade later, just using very fine tuned tools that develop more coherent images. I guess that we're close to maxing out how efficiently we're able to generate images and video in that manner, and the hard caps on how much creative direction we can have when using AI - as well as the limits to how long we can keep it coherent (e.g. long videos or a chronologically consistent set of images) - will prevent AI from progressing too far beyond what it is currently unless/until another breakthrough occurs.

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

2025-05-20 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.

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

2025-01-05 14:29:17The Rise of Graph RAGs and the Quest for Data Quality
As we enter a new year, it’s impossible to ignore the boom of retrieval-augmented generation (RAG) systems, particularly those leveraging graph-based approaches. The previous year saw a surge in advancements and discussions about Graph RAGs, driven by their potential to enhance large language models (LLMs), reduce hallucinations, and deliver more reliable outputs. Let’s dive into the trends, challenges, and strategies for making the most of Graph RAGs in artificial intelligence.
Booming Interest in Graph RAGs
Graph RAGs have dominated the conversation in AI circles. With new research papers and innovations emerging weekly, it’s clear that this approach is reshaping the landscape. These systems, especially those developed by tech giants like Microsoft, demonstrate how graphs can:
- Enhance LLM Outputs: By grounding responses in structured knowledge, graphs significantly reduce hallucinations.
- Support Complex Queries: Graphs excel at managing linked and connected data, making them ideal for intricate problem-solving.
Conferences on linked and connected data have increasingly focused on Graph RAGs, underscoring their central role in modern AI systems. However, the excitement around this technology has brought critical questions to the forefront: How do we ensure the quality of the graphs we’re building, and are they genuinely aligned with our needs?
Data Quality: The Foundation of Effective Graphs
A high-quality graph is the backbone of any successful RAG system. Constructing these graphs from unstructured data requires attention to detail and rigorous processes. Here’s why:
- Richness of Entities: Effective retrieval depends on graphs populated with rich, detailed entities.
- Freedom from Hallucinations: Poorly constructed graphs amplify inaccuracies rather than mitigating them.
Without robust data quality, even the most sophisticated Graph RAGs become ineffective. As a result, the focus must shift to refining the graph construction process. Improving data strategy and ensuring meticulous data preparation is essential to unlock the full potential of Graph RAGs.
Hybrid Graph RAGs and Variations
While standard Graph RAGs are already transformative, hybrid models offer additional flexibility and power. Hybrid RAGs combine structured graph data with other retrieval mechanisms, creating systems that:
- Handle diverse data sources with ease.
- Offer improved adaptability to complex queries.
Exploring these variations can open new avenues for AI systems, particularly in domains requiring structured and unstructured data processing.
Ontology: The Key to Graph Construction Quality
Ontology — defining how concepts relate within a knowledge domain — is critical for building effective graphs. While this might sound abstract, it’s a well-established field blending philosophy, engineering, and art. Ontology engineering provides the framework for:
- Defining Relationships: Clarifying how concepts connect within a domain.
- Validating Graph Structures: Ensuring constructed graphs are logically sound and align with domain-specific realities.
Traditionally, ontologists — experts in this discipline — have been integral to large enterprises and research teams. However, not every team has access to dedicated ontologists, leading to a significant challenge: How can teams without such expertise ensure the quality of their graphs?
How to Build Ontology Expertise in a Startup Team
For startups and smaller teams, developing ontology expertise may seem daunting, but it is achievable with the right approach:
- Assign a Knowledge Champion: Identify a team member with a strong analytical mindset and give them time and resources to learn ontology engineering.
- Provide Training: Invest in courses, workshops, or certifications in knowledge graph and ontology creation.
- Leverage Partnerships: Collaborate with academic institutions, domain experts, or consultants to build initial frameworks.
- Utilize Tools: Introduce ontology development tools like Protégé, OWL, or SHACL to simplify the creation and validation process.
- Iterate with Feedback: Continuously refine ontologies through collaboration with domain experts and iterative testing.
So, it is not always affordable for a startup to have a dedicated oncologist or knowledge engineer in a team, but you could involve consulters or build barefoot experts.
You could read about barefoot experts in my article :
Even startups can achieve robust and domain-specific ontology frameworks by fostering in-house expertise.
How to Find or Create Ontologies
For teams venturing into Graph RAGs, several strategies can help address the ontology gap:
-
Leverage Existing Ontologies: Many industries and domains already have open ontologies. For instance:
-
Public Knowledge Graphs: Resources like Wikipedia’s graph offer a wealth of structured knowledge.
- Industry Standards: Enterprises such as Siemens have invested in creating and sharing ontologies specific to their fields.
-
Business Framework Ontology (BFO): A valuable resource for enterprises looking to define business processes and structures.
-
Build In-House Expertise: If budgets allow, consider hiring knowledge engineers or providing team members with the resources and time to develop expertise in ontology creation.
-
Utilize LLMs for Ontology Construction: Interestingly, LLMs themselves can act as a starting point for ontology development:
-
Prompt-Based Extraction: LLMs can generate draft ontologies by leveraging their extensive training on graph data.
- Domain Expert Refinement: Combine LLM-generated structures with insights from domain experts to create tailored ontologies.
Parallel Ontology and Graph Extraction
An emerging approach involves extracting ontologies and graphs in parallel. While this can streamline the process, it presents challenges such as:
- Detecting Hallucinations: Differentiating between genuine insights and AI-generated inaccuracies.
- Ensuring Completeness: Ensuring no critical concepts are overlooked during extraction.
Teams must carefully validate outputs to ensure reliability and accuracy when employing this parallel method.
LLMs as Ontologists
While traditionally dependent on human expertise, ontology creation is increasingly supported by LLMs. These models, trained on vast amounts of data, possess inherent knowledge of many open ontologies and taxonomies. Teams can use LLMs to:
- Generate Skeleton Ontologies: Prompt LLMs with domain-specific information to draft initial ontology structures.
- Validate and Refine Ontologies: Collaborate with domain experts to refine these drafts, ensuring accuracy and relevance.
However, for validation and graph construction, formal tools such as OWL, SHACL, and RDF should be prioritized over LLMs to minimize hallucinations and ensure robust outcomes.
Final Thoughts: Unlocking the Power of Graph RAGs
The rise of Graph RAGs underscores a simple but crucial correlation: improving graph construction and data quality directly enhances retrieval systems. To truly harness this power, teams must invest in understanding ontologies, building quality graphs, and leveraging both human expertise and advanced AI tools.
As we move forward, the interplay between Graph RAGs and ontology engineering will continue to shape the future of AI. Whether through adopting existing frameworks or exploring innovative uses of LLMs, the path to success lies in a deep commitment to data quality and domain understanding.
Have you explored these technologies in your work? Share your experiences and insights — and stay tuned for more discussions on ontology extraction and its role in AI advancements. Cheers to a year of innovation!

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.

2025-01-02 18:13:31The Four-Layer Framework
Layer 1: Zoom Out
Start by looking at the big picture. What’s the subject about, and why does it matter? Focus on the overarching ideas and how they fit together. Think of this as the 30,000-foot view—it’s about understanding the "why" and "how" before diving into the "what."
Example: If you’re learning programming, start by understanding that it’s about giving logical instructions to computers to solve problems.
- Tip: Keep it simple. Summarize the subject in one or two sentences and avoid getting bogged down in specifics at this stage.
Once you have the big picture in mind, it’s time to start breaking it down.
Layer 2: Categorize and Connect
Now it’s time to break the subject into categories—like creating branches on a tree. This helps your brain organize information logically and see connections between ideas.
Example: Studying biology? Group concepts into categories like cells, genetics, and ecosystems.
- Tip: Use headings or labels to group similar ideas. Jot these down in a list or simple diagram to keep track.
With your categories in place, you’re ready to dive into the details that bring them to life.
Layer 3: Master the Details
Once you’ve mapped out the main categories, you’re ready to dive deeper. This is where you learn the nuts and bolts—like formulas, specific techniques, or key terminology. These details make the subject practical and actionable.
Example: In programming, this might mean learning the syntax for loops, conditionals, or functions in your chosen language.
- Tip: Focus on details that clarify the categories from Layer 2. Skip anything that doesn’t add to your understanding.
Now that you’ve mastered the essentials, you can expand your knowledge to include extra material.
Layer 4: Expand Your Horizons
Finally, move on to the extra material—less critical facts, trivia, or edge cases. While these aren’t essential to mastering the subject, they can be useful in specialized discussions or exams.
Example: Learn about rare programming quirks or historical trivia about a language’s development.
- Tip: Spend minimal time here unless it’s necessary for your goals. It’s okay to skim if you’re short on time.
Pro Tips for Better Learning
1. Use Active Recall and Spaced Repetition
Test yourself without looking at notes. Review what you’ve learned at increasing intervals—like after a day, a week, and a month. This strengthens memory by forcing your brain to actively retrieve information.
2. Map It Out
Create visual aids like diagrams or concept maps to clarify relationships between ideas. These are particularly helpful for organizing categories in Layer 2.
3. Teach What You Learn
Explain the subject to someone else as if they’re hearing it for the first time. Teaching exposes any gaps in your understanding and helps reinforce the material.
4. Engage with LLMs and Discuss Concepts
Take advantage of tools like ChatGPT or similar large language models to explore your topic in greater depth. Use these tools to:
- Ask specific questions to clarify confusing points.
- Engage in discussions to simulate real-world applications of the subject.
- Generate examples or analogies that deepen your understanding.Tip: Use LLMs as a study partner, but don’t rely solely on them. Combine these insights with your own critical thinking to develop a well-rounded perspective.
Get Started
Ready to try the Four-Layer Method? Take 15 minutes today to map out the big picture of a topic you’re curious about—what’s it all about, and why does it matter? By building your understanding step by step, you’ll master the subject with less stress and more confidence.

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

It provides real-time GPU metrics, supports integration with tools like Home Assistant, and offers flexible power management and PCIe link speed management based on workload and thermal conditions.
- GPU Utilization Monitoring: Utilization, memory usage, temperature, fan speed, and power consumption.
- Automated Power Limiting: Adjusts power limits dynamically based on temperature thresholds and total power caps, configurable per GPU or globally.
- Cross-GPU Coordination: Total power budget applies across multiple GPUs in the same system.
- PCIe Link Speed Management: Controls minimum and maximum PCIe link speeds with idle thresholds for power optimization.
- Home Assistant Integration: Uses the built-in RESTful platform and template sensors.

@ 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.

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

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

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

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

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

2024-12-15 15:09:52Che cosa significherebbe trattare l'IA come uno strumento invece che come una persona?
Dall’avvio di ChatGPT, le esplorazioni in due direzioni hanno preso velocità.
La prima direzione riguarda le capacità tecniche. Quanto grande possiamo addestrare un modello? Quanto bene può rispondere alle domande del SAT? Con quanta efficienza possiamo distribuirlo?
La seconda direzione riguarda il design dell’interazione. Come comunichiamo con un modello? Come possiamo usarlo per un lavoro utile? Quale metafora usiamo per ragionare su di esso?
La prima direzione è ampiamente seguita e enormemente finanziata, e per una buona ragione: i progressi nelle capacità tecniche sono alla base di ogni possibile applicazione. Ma la seconda è altrettanto cruciale per il campo e ha enormi incognite. Siamo solo a pochi anni dall’inizio dell’era dei grandi modelli. Quali sono le probabilità che abbiamo già capito i modi migliori per usarli?
Propongo una nuova modalità di interazione, in cui i modelli svolgano il ruolo di applicazioni informatiche (ad esempio app per telefoni): fornendo un’interfaccia grafica, interpretando gli input degli utenti e aggiornando il loro stato. In questa modalità, invece di essere un “agente” che utilizza un computer per conto dell’essere umano, l’IA può fornire un ambiente informatico più ricco e potente che possiamo utilizzare.
Metafore per l’interazione
Al centro di un’interazione c’è una metafora che guida le aspettative di un utente su un sistema. I primi giorni dell’informatica hanno preso metafore come “scrivanie”, “macchine da scrivere”, “fogli di calcolo” e “lettere” e le hanno trasformate in equivalenti digitali, permettendo all’utente di ragionare sul loro comportamento. Puoi lasciare qualcosa sulla tua scrivania e tornare a prenderlo; hai bisogno di un indirizzo per inviare una lettera. Man mano che abbiamo sviluppato una conoscenza culturale di questi dispositivi, la necessità di queste particolari metafore è scomparsa, e con esse i design di interfaccia skeumorfici che le rafforzavano. Come un cestino o una matita, un computer è ora una metafora di se stesso.
La metafora dominante per i grandi modelli oggi è modello-come-persona. Questa è una metafora efficace perché le persone hanno capacità estese che conosciamo intuitivamente. Implica che possiamo avere una conversazione con un modello e porgli domande; che il modello possa collaborare con noi su un documento o un pezzo di codice; che possiamo assegnargli un compito da svolgere da solo e che tornerà quando sarà finito.
Tuttavia, trattare un modello come una persona limita profondamente il nostro modo di pensare all’interazione con esso. Le interazioni umane sono intrinsecamente lente e lineari, limitate dalla larghezza di banda e dalla natura a turni della comunicazione verbale. Come abbiamo tutti sperimentato, comunicare idee complesse in una conversazione è difficile e dispersivo. Quando vogliamo precisione, ci rivolgiamo invece a strumenti, utilizzando manipolazioni dirette e interfacce visive ad alta larghezza di banda per creare diagrammi, scrivere codice e progettare modelli CAD. Poiché concepiamo i modelli come persone, li utilizziamo attraverso conversazioni lente, anche se sono perfettamente in grado di accettare input diretti e rapidi e di produrre risultati visivi. Le metafore che utilizziamo limitano le esperienze che costruiamo, e la metafora modello-come-persona ci impedisce di esplorare il pieno potenziale dei grandi modelli.
Per molti casi d’uso, e specialmente per il lavoro produttivo, credo che il futuro risieda in un’altra metafora: modello-come-computer.
Usare un’IA come un computer
Sotto la metafora modello-come-computer, interagiremo con i grandi modelli seguendo le intuizioni che abbiamo sulle applicazioni informatiche (sia su desktop, tablet o telefono). Nota che ciò non significa che il modello sarà un’app tradizionale più di quanto il desktop di Windows fosse una scrivania letterale. “Applicazione informatica” sarà un modo per un modello di rappresentarsi a noi. Invece di agire come una persona, il modello agirà come un computer.
Agire come un computer significa produrre un’interfaccia grafica. Al posto del flusso lineare di testo in stile telescrivente fornito da ChatGPT, un sistema modello-come-computer genererà qualcosa che somiglia all’interfaccia di un’applicazione moderna: pulsanti, cursori, schede, immagini, grafici e tutto il resto. Questo affronta limitazioni chiave dell’interfaccia di chat standard modello-come-persona:
-
Scoperta. Un buon strumento suggerisce i suoi usi. Quando l’unica interfaccia è una casella di testo vuota, spetta all’utente capire cosa fare e comprendere i limiti del sistema. La barra laterale Modifica in Lightroom è un ottimo modo per imparare l’editing fotografico perché non si limita a dirti cosa può fare questa applicazione con una foto, ma cosa potresti voler fare. Allo stesso modo, un’interfaccia modello-come-computer per DALL-E potrebbe mostrare nuove possibilità per le tue generazioni di immagini.
-
Efficienza. La manipolazione diretta è più rapida che scrivere una richiesta a parole. Per continuare l’esempio di Lightroom, sarebbe impensabile modificare una foto dicendo a una persona quali cursori spostare e di quanto. Ci vorrebbe un giorno intero per chiedere un’esposizione leggermente più bassa e una vibranza leggermente più alta, solo per vedere come apparirebbe. Nella metafora modello-come-computer, il modello può creare strumenti che ti permettono di comunicare ciò che vuoi più efficientemente e quindi di fare le cose più rapidamente.
A differenza di un’app tradizionale, questa interfaccia grafica è generata dal modello su richiesta. Questo significa che ogni parte dell’interfaccia che vedi è rilevante per ciò che stai facendo in quel momento, inclusi i contenuti specifici del tuo lavoro. Significa anche che, se desideri un’interfaccia più ampia o diversa, puoi semplicemente richiederla. Potresti chiedere a DALL-E di produrre alcuni preset modificabili per le sue impostazioni ispirati da famosi artisti di schizzi. Quando clicchi sul preset Leonardo da Vinci, imposta i cursori per disegni prospettici altamente dettagliati in inchiostro nero. Se clicchi su Charles Schulz, seleziona fumetti tecnicolor 2D a basso dettaglio.
Una bicicletta della mente proteiforme
La metafora modello-come-persona ha una curiosa tendenza a creare distanza tra l’utente e il modello, rispecchiando il divario di comunicazione tra due persone che può essere ridotto ma mai completamente colmato. A causa della difficoltà e del costo di comunicare a parole, le persone tendono a suddividere i compiti tra loro in blocchi grandi e il più indipendenti possibile. Le interfacce modello-come-persona seguono questo schema: non vale la pena dire a un modello di aggiungere un return statement alla tua funzione quando è più veloce scriverlo da solo. Con il sovraccarico della comunicazione, i sistemi modello-come-persona sono più utili quando possono fare un intero blocco di lavoro da soli. Fanno le cose per te.
Questo contrasta con il modo in cui interagiamo con i computer o altri strumenti. Gli strumenti producono feedback visivi in tempo reale e sono controllati attraverso manipolazioni dirette. Hanno un overhead comunicativo così basso che non è necessario specificare un blocco di lavoro indipendente. Ha più senso mantenere l’umano nel loop e dirigere lo strumento momento per momento. Come stivali delle sette leghe, gli strumenti ti permettono di andare più lontano a ogni passo, ma sei ancora tu a fare il lavoro. Ti permettono di fare le cose più velocemente.
Considera il compito di costruire un sito web usando un grande modello. Con le interfacce di oggi, potresti trattare il modello come un appaltatore o un collaboratore. Cercheresti di scrivere a parole il più possibile su come vuoi che il sito appaia, cosa vuoi che dica e quali funzionalità vuoi che abbia. Il modello genererebbe una prima bozza, tu la eseguirai e poi fornirai un feedback. “Fai il logo un po’ più grande”, diresti, e “centra quella prima immagine principale”, e “deve esserci un pulsante di login nell’intestazione”. Per ottenere esattamente ciò che vuoi, invierai una lista molto lunga di richieste sempre più minuziose.
Un’interazione alternativa modello-come-computer sarebbe diversa: invece di costruire il sito web, il modello genererebbe un’interfaccia per te per costruirlo, dove ogni input dell’utente a quell’interfaccia interroga il grande modello sotto il cofano. Forse quando descrivi le tue necessità creerebbe un’interfaccia con una barra laterale e una finestra di anteprima. All’inizio la barra laterale contiene solo alcuni schizzi di layout che puoi scegliere come punto di partenza. Puoi cliccare su ciascuno di essi, e il modello scrive l’HTML per una pagina web usando quel layout e lo visualizza nella finestra di anteprima. Ora che hai una pagina su cui lavorare, la barra laterale guadagna opzioni aggiuntive che influenzano la pagina globalmente, come accoppiamenti di font e schemi di colore. L’anteprima funge da editor WYSIWYG, permettendoti di afferrare elementi e spostarli, modificarne i contenuti, ecc. A supportare tutto ciò è il modello, che vede queste azioni dell’utente e riscrive la pagina per corrispondere ai cambiamenti effettuati. Poiché il modello può generare un’interfaccia per aiutare te e lui a comunicare più efficientemente, puoi esercitare più controllo sul prodotto finale in meno tempo.
La metafora modello-come-computer ci incoraggia a pensare al modello come a uno strumento con cui interagire in tempo reale piuttosto che a un collaboratore a cui assegnare compiti. Invece di sostituire un tirocinante o un tutor, può essere una sorta di bicicletta proteiforme per la mente, una che è sempre costruita su misura esattamente per te e il terreno che intendi attraversare.
Un nuovo paradigma per l’informatica?
I modelli che possono generare interfacce su richiesta sono una frontiera completamente nuova nell’informatica. Potrebbero essere un paradigma del tutto nuovo, con il modo in cui cortocircuitano il modello di applicazione esistente. Dare agli utenti finali il potere di creare e modificare app al volo cambia fondamentalmente il modo in cui interagiamo con i computer. Al posto di una singola applicazione statica costruita da uno sviluppatore, un modello genererà un’applicazione su misura per l’utente e le sue esigenze immediate. Al posto della logica aziendale implementata nel codice, il modello interpreterà gli input dell’utente e aggiornerà l’interfaccia utente. È persino possibile che questo tipo di interfaccia generativa sostituisca completamente il sistema operativo, generando e gestendo interfacce e finestre al volo secondo necessità.
All’inizio, l’interfaccia generativa sarà un giocattolo, utile solo per l’esplorazione creativa e poche altre applicazioni di nicchia. Dopotutto, nessuno vorrebbe un’app di posta elettronica che occasionalmente invia email al tuo ex e mente sulla tua casella di posta. Ma gradualmente i modelli miglioreranno. Anche mentre si spingeranno ulteriormente nello spazio di esperienze completamente nuove, diventeranno lentamente abbastanza affidabili da essere utilizzati per un lavoro reale.
Piccoli pezzi di questo futuro esistono già. Anni fa Jonas Degrave ha dimostrato che ChatGPT poteva fare una buona simulazione di una riga di comando Linux. Allo stesso modo, websim.ai utilizza un LLM per generare siti web su richiesta mentre li navighi. Oasis, GameNGen e DIAMOND addestrano modelli video condizionati sull’azione su singoli videogiochi, permettendoti di giocare ad esempio a Doom dentro un grande modello. E Genie 2 genera videogiochi giocabili da prompt testuali. L’interfaccia generativa potrebbe ancora sembrare un’idea folle, ma non è così folle.
Ci sono enormi domande aperte su come apparirà tutto questo. Dove sarà inizialmente utile l’interfaccia generativa? Come condivideremo e distribuiremo le esperienze che creiamo collaborando con il modello, se esistono solo come contesto di un grande modello? Vorremmo davvero farlo? Quali nuovi tipi di esperienze saranno possibili? Come funzionerà tutto questo in pratica? I modelli genereranno interfacce come codice o produrranno direttamente pixel grezzi?
Non conosco ancora queste risposte. Dovremo sperimentare e scoprirlo!Che cosa significherebbe trattare l'IA come uno strumento invece che come una persona?

2024-12-07 15:06:43I started a long series of articles about how to model different types of knowledge graphs in the relational model, which makes on-device memory models for AI agents possible.
We model-directed graphs
Also, graphs of entities
We even model hypergraphs
Last time, we discussed why classical triple and simple knowledge graphs are insufficient for AI agents and complex memory, especially in the domain of time-aware or multi-model knowledge.
So why do we need metagraphs, and what kind of challenge could they help us to solve?
- complex and nested event and temporal context and temporal relations as edges
- multi-mode and multilingual knowledge
- human-like memory for AI agents that has multiple contexts and relations between knowledge in neuron-like networks
MetaGraphs
A meta graph is a concept that extends the idea of a graph by allowing edges to become graphs. Meta Edges connect a set of nodes, which could also be subgraphs. So, at some level, node and edge are pretty similar in properties but act in different roles in a different context.
Also, in some cases, edges could be referenced as nodes.
This approach enables the representation of more complex relationships and hierarchies than a traditional graph structure allows. Let’s break down each term to understand better metagraphs and how they differ from hypergraphs and graphs.Graph Basics
- A standard graph has a set of nodes (or vertices) and edges (connections between nodes).
- Edges are generally simple and typically represent a binary relationship between two nodes.
- For instance, an edge in a social network graph might indicate a “friend” relationship between two people (nodes).
Hypergraph
- A hypergraph extends the concept of an edge by allowing it to connect any number of nodes, not just two.
- Each connection, called a hyperedge, can link multiple nodes.
- This feature allows hypergraphs to model more complex relationships involving multiple entities simultaneously. For example, a hyperedge in a hypergraph could represent a project team, connecting all team members in a single relation.
- Despite its flexibility, a hypergraph doesn’t capture hierarchical or nested structures; it only generalizes the number of connections in an edge.
Metagraph
- A metagraph allows the edges to be graphs themselves. This means each edge can contain its own nodes and edges, creating nested, hierarchical structures.
- In a meta graph, an edge could represent a relationship defined by a graph. For instance, a meta graph could represent a network of organizations where each organization’s structure (departments and connections) is represented by its own internal graph and treated as an edge in the larger meta graph.
- This recursive structure allows metagraphs to model complex data with multiple layers of abstraction. They can capture multi-node relationships (as in hypergraphs) and detailed, structured information about each relationship.
Named Graphs and Graph of Graphs
As you can notice, the structure of a metagraph is quite complex and could be complex to model in relational and classical RDF setups. It could create a challenge of luck of tools and software solutions for your problem.
If you need to model nested graphs, you could use a much simpler model of Named graphs, which could take you quite far.The concept of the named graph came from the RDF community, which needed to group some sets of triples. In this way, you form subgraphs inside an existing graph. You could refer to the subgraph as a regular node. This setup simplifies complex graphs, introduces hierarchies, and even adds features and properties of hypergraphs while keeping a directed nature.
It looks complex, but it is not so hard to model it with a slight modification of a directed graph.
So, the node could host graphs inside. Let's reflect this fact with a location for a node. If a node belongs to a main graph, we could set the location to null or introduce a main node . it is up to youNodes could have edges to nodes in different subgraphs. This structure allows any kind of nesting graphs. Edges stay location-free
Meta Graphs in Relational Model
Let’s try to make several attempts to model different meta-graphs with some constraints.
Directed Metagraph where edges are not used as nodes and could not contain subgraphs
In this case, the edge always points to two sets of nodes. This introduces an overhead of creating a node set for a single node. In this model, we can model empty node sets that could require application-level constraints to prevent such cases.
Directed Metagraph where edges are not used as nodes and could contain subgraphs
Adding a node set that could model a subgraph located in an edge is easy but could be separate from in-vertex or out-vert.
I also do not see a direct need to include subgraphs to a node, as we could just use a node set interchangeably, but it still could be a case.Directed Metagraph where edges are used as nodes and could contain subgraphs
As you can notice, we operate all the time with node sets. We could simply allow the extension node set to elements set that include node and edge IDs, but in this case, we need to use uuid or any other strategy to differentiate node IDs from edge IDs. In this case, we have a collision of ephemeral edges or ephemeral nodes when we want to change the role and purpose of the node as an edge or vice versa.
A full-scale metagraph model is way too complex for a relational database.
So we need a better model.Now, we have more flexibility but loose structural constraints. We cannot show that the element should have one vertex, one vertex, or both. This type of constraint has been moved to the application level. Also, the crucial question is about query and retrieval needs.
Any meta-graph model should be more focused on domain and needs and should be used in raw form. We did it for a pure theoretical purpose. -

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

2024-12-07 15:03:06Hey folks! Today, let’s dive into the intriguing world of neurosymbolic approaches, retrieval-augmented generation (RAG), and personal knowledge graphs (PKGs). Together, these concepts hold much potential for bringing true reasoning capabilities to large language models (LLMs). So, let’s break down how symbolic logic, knowledge graphs, and modern AI can come together to empower future AI systems to reason like humans.
The Neurosymbolic Approach: What It Means ?
Neurosymbolic AI combines two historically separate streams of artificial intelligence: symbolic reasoning and neural networks. Symbolic AI uses formal logic to process knowledge, similar to how we might solve problems or deduce information. On the other hand, neural networks, like those underlying GPT-4, focus on learning patterns from vast amounts of data — they are probabilistic statistical models that excel in generating human-like language and recognizing patterns but often lack deep, explicit reasoning.
While GPT-4 can produce impressive text, it’s still not very effective at reasoning in a truly logical way. Its foundation, transformers, allows it to excel in pattern recognition, but the models struggle with reasoning because, at their core, they rely on statistical probabilities rather than true symbolic logic. This is where neurosymbolic methods and knowledge graphs come in.
Symbolic Calculations and the Early Vision of AI
If we take a step back to the 1950s, the vision for artificial intelligence was very different. Early AI research was all about symbolic reasoning — where computers could perform logical calculations to derive new knowledge from a given set of rules and facts. Languages like Lisp emerged to support this vision, enabling programs to represent data and code as interchangeable symbols. Lisp was designed to be homoiconic, meaning it treated code as manipulatable data, making it capable of self-modification — a huge leap towards AI systems that could, in theory, understand and modify their own operations.
Lisp: The Earlier AI-Language
Lisp, short for “LISt Processor,” was developed by John McCarthy in 1958, and it became the cornerstone of early AI research. Lisp’s power lay in its flexibility and its use of symbolic expressions, which allowed developers to create programs that could manipulate symbols in ways that were very close to human reasoning. One of the most groundbreaking features of Lisp was its ability to treat code as data, known as homoiconicity, which meant that Lisp programs could introspect and transform themselves dynamically. This ability to adapt and modify its own structure gave Lisp an edge in tasks that required a form of self-awareness, which was key in the early days of AI when researchers were exploring what it meant for machines to “think.”
Lisp was not just a programming language—it represented the vision for artificial intelligence, where machines could evolve their understanding and rewrite their own programming. This idea formed the conceptual basis for many of the self-modifying and adaptive algorithms that are still explored today in AI research. Despite its decline in mainstream programming, Lisp’s influence can still be seen in the concepts used in modern machine learning and symbolic AI approaches.
Prolog: Formal Logic and Deductive Reasoning
In the 1970s, Prolog was developed—a language focused on formal logic and deductive reasoning. Unlike Lisp, based on lambda calculus, Prolog operates on formal logic rules, allowing it to perform deductive reasoning and solve logical puzzles. This made Prolog an ideal candidate for expert systems that needed to follow a sequence of logical steps, such as medical diagnostics or strategic planning.
Prolog, like Lisp, allowed symbols to be represented, understood, and used in calculations, creating another homoiconic language that allows reasoning. Prolog’s strength lies in its rule-based structure, which is well-suited for tasks that require logical inference and backtracking. These features made it a powerful tool for expert systems and AI research in the 1970s and 1980s.
The language is declarative in nature, meaning that you define the problem, and Prolog figures out how to solve it. By using formal logic and setting constraints, Prolog systems can derive conclusions from known facts, making it highly effective in fields requiring explicit logical frameworks, such as legal reasoning, diagnostics, and natural language understanding. These symbolic approaches were later overshadowed during the AI winter — but the ideas never really disappeared. They just evolved.
Solvers and Their Role in Complementing LLMs
One of the most powerful features of Prolog and similar logic-based systems is their use of solvers. Solvers are mechanisms that can take a set of rules and constraints and automatically find solutions that satisfy these conditions. This capability is incredibly useful when combined with LLMs, which excel at generating human-like language but need help with logical consistency and structured reasoning.
For instance, imagine a scenario where an LLM needs to answer a question involving multiple logical steps or a complex query that requires deducing facts from various pieces of information. In this case, a solver can derive valid conclusions based on a given set of logical rules, providing structured answers that the LLM can then articulate in natural language. This allows the LLM to retrieve information and ensure the logical integrity of its responses, leading to much more robust answers.
Solvers are also ideal for handling constraint satisfaction problems — situations where multiple conditions must be met simultaneously. In practical applications, this could include scheduling tasks, generating optimal recommendations, or even diagnosing issues where a set of symptoms must match possible diagnoses. Prolog’s solver capabilities and LLM’s natural language processing power can make these systems highly effective at providing intelligent, rule-compliant responses that traditional LLMs would struggle to produce alone.
By integrating neurosymbolic methods that utilize solvers, we can provide LLMs with a form of deductive reasoning that is missing from pure deep-learning approaches. This combination has the potential to significantly improve the quality of outputs for use-cases that require explicit, structured problem-solving, from legal queries to scientific research and beyond. Solvers give LLMs the backbone they need to not just generate answers but to do so in a way that respects logical rigor and complex constraints.
Graph of Rules for Enhanced Reasoning
Another powerful concept that complements LLMs is using a graph of rules. A graph of rules is essentially a structured collection of logical rules that interconnect in a network-like structure, defining how various entities and their relationships interact. This structured network allows for complex reasoning and information retrieval, as well as the ability to model intricate relationships between different pieces of knowledge.
In a graph of rules, each node represents a rule, and the edges define relationships between those rules — such as dependencies or causal links. This structure can be used to enhance LLM capabilities by providing them with a formal set of rules and relationships to follow, which improves logical consistency and reasoning depth. When an LLM encounters a problem or a question that requires multiple logical steps, it can traverse this graph of rules to generate an answer that is not only linguistically fluent but also logically robust.
For example, in a healthcare application, a graph of rules might include nodes for medical symptoms, possible diagnoses, and recommended treatments. When an LLM receives a query regarding a patient’s symptoms, it can use the graph to traverse from symptoms to potential diagnoses and then to treatment options, ensuring that the response is coherent and medically sound. The graph of rules guides reasoning, enabling LLMs to handle complex, multi-step questions that involve chains of reasoning, rather than merely generating surface-level responses.
Graphs of rules also enable modular reasoning, where different sets of rules can be activated based on the context or the type of question being asked. This modularity is crucial for creating adaptive AI systems that can apply specific sets of logical frameworks to distinct problem domains, thereby greatly enhancing their versatility. The combination of neural fluency with rule-based structure gives LLMs the ability to conduct more advanced reasoning, ultimately making them more reliable and effective in domains where accuracy and logical consistency are critical.
By implementing a graph of rules, LLMs are empowered to perform deductive reasoning alongside their generative capabilities, creating responses that are not only compelling but also logically aligned with the structured knowledge available in the system. This further enhances their potential applications in fields such as law, engineering, finance, and scientific research — domains where logical consistency is as important as linguistic coherence.
Enhancing LLMs with Symbolic Reasoning
Now, with LLMs like GPT-4 being mainstream, there is an emerging need to add real reasoning capabilities to them. This is where neurosymbolic approaches shine. Instead of pitting neural networks against symbolic reasoning, these methods combine the best of both worlds. The neural aspect provides language fluency and recognition of complex patterns, while the symbolic side offers real reasoning power through formal logic and rule-based frameworks.
Personal Knowledge Graphs (PKGs) come into play here as well. Knowledge graphs are data structures that encode entities and their relationships — they’re essentially semantic networks that allow for structured information retrieval. When integrated with neurosymbolic approaches, LLMs can use these graphs to answer questions in a far more contextual and precise way. By retrieving relevant information from a knowledge graph, they can ground their responses in well-defined relationships, thus improving both the relevance and the logical consistency of their answers.
Imagine combining an LLM with a graph of rules that allow it to reason through the relationships encoded in a personal knowledge graph. This could involve using deductive databases to form a sophisticated way to represent and reason with symbolic data — essentially constructing a powerful hybrid system that uses LLM capabilities for language fluency and rule-based logic for structured problem-solving.
My Research on Deductive Databases and Knowledge Graphs
I recently did some research on modeling knowledge graphs using deductive databases, such as DataLog — which can be thought of as a limited, data-oriented version of Prolog. What I’ve found is that it’s possible to use formal logic to model knowledge graphs, ontologies, and complex relationships elegantly as rules in a deductive system. Unlike classical RDF or traditional ontology-based models, which sometimes struggle with complex or evolving relationships, a deductive approach is more flexible and can easily support dynamic rules and reasoning.
Prolog and similar logic-driven frameworks can complement LLMs by handling the parts of reasoning where explicit rule-following is required. LLMs can benefit from these rule-based systems for tasks like entity recognition, logical inferences, and constructing or traversing knowledge graphs. We can even create a graph of rules that governs how relationships are formed or how logical deductions can be performed.
The future is really about creating an AI that is capable of both deep contextual understanding (using the powerful generative capacity of LLMs) and true reasoning (through symbolic systems and knowledge graphs). With the neurosymbolic approach, these AIs could be equipped not just to generate information but to explain their reasoning, form logical conclusions, and even improve their own understanding over time — getting us a step closer to true artificial general intelligence.
Why It Matters for LLM Employment
Using neurosymbolic RAG (retrieval-augmented generation) in conjunction with personal knowledge graphs could revolutionize how LLMs work in real-world applications. Imagine an LLM that understands not just language but also the relationships between different concepts — one that can navigate, reason, and explain complex knowledge domains by actively engaging with a personalized set of facts and rules.
This could lead to practical applications in areas like healthcare, finance, legal reasoning, or even personal productivity — where LLMs can help users solve complex problems logically, providing relevant information and well-justified reasoning paths. The combination of neural fluency with symbolic accuracy and deductive power is precisely the bridge we need to move beyond purely predictive AI to truly intelligent systems.

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.

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

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

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

2024-12-07 14:54:46Introduction: Personal Knowledge Graphs and Linked Data
We will explore the world of personal knowledge graphs and discuss how they can be used to model complex information structures. Personal knowledge graphs aren’t just abstract collections of nodes and edges—they encode meaningful relationships, contextualizing data in ways that enrich our understanding of it. While the core structure might be a directed graph, we layer semantic meaning on top, enabling nuanced connections between data points.
The origin of knowledge graphs is deeply tied to concepts from linked data and the semantic web, ideas that emerged to better link scattered pieces of information across the web. This approach created an infrastructure where data islands could connect — facilitating everything from more insightful AI to improved personal data management.
In this article, we will explore how these ideas have evolved into tools for modeling AI’s semantic memory and look at how knowledge graphs can serve as a flexible foundation for encoding rich data contexts. We’ll specifically discuss three major paradigms: RDF (Resource Description Framework), property graphs, and a third way of modeling entities as graphs of graphs. Let’s get started.
Intro to RDF
The Resource Description Framework (RDF) has been one of the fundamental standards for linked data and knowledge graphs. RDF allows data to be modeled as triples: subject, predicate, and object. Essentially, you can think of it as a structured way to describe relationships: “X has a Y called Z.” For instance, “Berlin has a population of 3.5 million.” This modeling approach is quite flexible because RDF uses unique identifiers — usually URIs — to point to data entities, making linking straightforward and coherent.
RDFS, or RDF Schema, extends RDF to provide a basic vocabulary to structure the data even more. This lets us describe not only individual nodes but also relationships among types of data entities, like defining a class hierarchy or setting properties. For example, you could say that “Berlin” is an instance of a “City” and that cities are types of “Geographical Entities.” This kind of organization helps establish semantic meaning within the graph.
RDF and Advanced Topics
Lists and Sets in RDF
RDF also provides tools to model more complex data structures such as lists and sets, enabling the grouping of nodes. This extension makes it easier to model more natural, human-like knowledge, for example, describing attributes of an entity that may have multiple values. By adding RDF Schema and OWL (Web Ontology Language), you gain even more expressive power — being able to define logical rules or even derive new relationships from existing data.
Graph of Graphs
A significant feature of RDF is the ability to form complex nested structures, often referred to as graphs of graphs. This allows you to create “named graphs,” essentially subgraphs that can be independently referenced. For example, you could create a named graph for a particular dataset describing Berlin and another for a different geographical area. Then, you could connect them, allowing for more modular and reusable knowledge modeling.
Property Graphs
While RDF provides a robust framework, it’s not always the easiest to work with due to its heavy reliance on linking everything explicitly. This is where property graphs come into play. Property graphs are less focused on linking everything through triples and allow more expressive properties directly within nodes and edges.
For example, instead of using triples to represent each detail, a property graph might let you store all properties about an entity (e.g., “Berlin”) directly in a single node. This makes property graphs more intuitive for many developers and engineers because they more closely resemble object-oriented structures: you have entities (nodes) that possess attributes (properties) and are connected to other entities through relationships (edges).
The significant benefit here is a condensed representation, which speeds up traversal and queries in some scenarios. However, this also introduces a trade-off: while property graphs are more straightforward to query and maintain, they lack some complex relationship modeling features RDF offers, particularly when connecting properties to each other.
Graph of Graphs and Subgraphs for Entity Modeling
A third approach — which takes elements from RDF and property graphs — involves modeling entities using subgraphs or nested graphs. In this model, each entity can be represented as a graph. This allows for a detailed and flexible description of attributes without exploding every detail into individual triples or lump them all together into properties.
For instance, consider a person entity with a complex employment history. Instead of representing every employment detail in one node (as in a property graph), or as several linked nodes (as in RDF), you can treat the employment history as a subgraph. This subgraph could then contain nodes for different jobs, each linked with specific properties and connections. This approach keeps the complexity where it belongs and provides better flexibility when new attributes or entities need to be added.
Hypergraphs and Metagraphs
When discussing more advanced forms of graphs, we encounter hypergraphs and metagraphs. These take the idea of relationships to a new level. A hypergraph allows an edge to connect more than two nodes, which is extremely useful when modeling scenarios where relationships aren’t just pairwise. For example, a “Project” could connect multiple “People,” “Resources,” and “Outcomes,” all in a single edge. This way, hypergraphs help in reducing the complexity of modeling high-order relationships.
Metagraphs, on the other hand, enable nodes and edges to themselves be represented as graphs. This is an extremely powerful feature when we consider the needs of artificial intelligence, as it allows for the modeling of relationships between relationships, an essential aspect for any system that needs to capture not just facts, but their interdependencies and contexts.
Balancing Structure and Properties
One of the recurring challenges when modeling knowledge is finding the balance between structure and properties. With RDF, you get high flexibility and standardization, but complexity can quickly escalate as you decompose everything into triples. Property graphs simplify the representation by using attributes but lose out on the depth of connection modeling. Meanwhile, the graph-of-graphs approach and hypergraphs offer advanced modeling capabilities at the cost of increased computational complexity.
So, how do you decide which model to use? It comes down to your use case. RDF and nested graphs are strong contenders if you need deep linkage and are working with highly variable data. For more straightforward, engineer-friendly modeling, property graphs shine. And when dealing with very complex multi-way relationships or meta-level knowledge, hypergraphs and metagraphs provide the necessary tools.
The key takeaway is that only some approaches are perfect. Instead, it’s all about the modeling goals: how do you want to query the graph, what relationships are meaningful, and how much complexity are you willing to manage?
Conclusion
Modeling AI semantic memory using knowledge graphs is a challenging but rewarding process. The different approaches — RDF, property graphs, and advanced graph modeling techniques like nested graphs and hypergraphs — each offer unique strengths and weaknesses. Whether you are building a personal knowledge graph or scaling up to AI that integrates multiple streams of linked data, it’s essential to understand the trade-offs each approach brings.
In the end, the choice of representation comes down to the nature of your data and your specific needs for querying and maintaining semantic relationships. The world of knowledge graphs is vast, with many tools and frameworks to explore. Stay connected and keep experimenting to find the balance that works for your projects.

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

2024-12-07 14:52:47The temporal semantics and temporal and time-aware knowledge graphs. We have different memory models for artificial intelligence agents. We all try to mimic somehow how the brain works, or at least how the declarative memory of the brain works. We have the split of episodic memory and semantic memory. And we also have a lot of theories, right?
Declarative Memory of the Human Brain
How is the semantic memory formed? We all know that our brain stores semantic memory quite close to the concept we have with the personal knowledge graphs, that it’s connected entities. They form a connection with each other and all those things. So far, so good. And actually, then we have a lot of concepts, how the episodic memory and our experiences gets transmitted to the semantic:
- hippocampus indexing and retrieval
- sanitization of episodic memories
- episodic-semantic shift theory
They all give a different perspective on how different parts of declarative memory cooperate.
We know that episodic memories get semanticized over time. You have semantic knowledge without the notion of time, and probably, your episodic memory is just decayed.
But, you know, it’s still an open question:
do we want to mimic an AI agent’s memory as a human brain memory, or do we want to create something different?
It’s an open question to which we have no good answer. And if you go to the theory of neuroscience and check how episodic and semantic memory interfere, you will still find a lot of theories, yeah?
Some of them say that you have the hippocampus that keeps the indexes of the memory. Some others will say that you semantic the episodic memory. Some others say that you have some separate process that digests the episodic and experience to the semantics. But all of them agree on the plan that it’s operationally two separate areas of memories and even two separate regions of brain, and the semantic, it’s more, let’s say, protected.
So it’s harder to forget the semantical facts than the episodes and everything. And what I’m thinking about for a long time, it’s this, you know, the semantic memory.
Temporal Semantics
It’s memory about the facts, but you somehow mix the time information with the semantics. I already described a lot of things, including how we could combine time with knowledge graphs and how people do it.
There are multiple ways we could persist such information, but we all hit the wall because the complexity of time and the semantics of time are highly complex concepts.
Time in a Semantic context is not a timestamp.
What I mean is that when you have a fact, and you just mentioned that I was there at this particular moment, like, I don’t know, 15:40 on Monday, it’s already awake because we don’t know which Monday, right? So you need to give the exact date, but usually, you do not have experiences like that.
You do not record your memories like that, except you do the journaling and all of the things. So, usually, you have no direct time references. What I mean is that you could say that I was there and it was some event, blah, blah, blah.
Somehow, we form a chain of events that connect with each other and maybe will be connected to some period of time if we are lucky enough. This means that we could not easily represent temporal-aware information as just a timestamp or validity and all of the things.
For sure, the validity of the knowledge graphs (simple quintuple with start and end dates)is a big topic, and it could solve a lot of things. It could solve a lot of the time cases. It’s super simple because you give the end and start dates, and you are done, but it does not answer facts that have a relative time or time information in facts . It could solve many use cases but struggle with facts in an indirect temporal context. I like the simplicity of this idea. But the problem of this approach that in most cases, we simply don’t have these timestamps. We don’t have the timestamp where this information starts and ends. And it’s not modeling many events in our life, especially if you have the processes or ongoing activities or recurrent events.
I’m more about thinking about the time of semantics, where you have a time model as a hybrid clock or some global clock that does the partial ordering of the events. It’s mean that you have the chain of the experiences and you have the chain of the facts that have the different time contexts.
We could deduct the time from this chain of the events. But it’s a big, big topic for the research. But what I want to achieve, actually, it’s not separation on episodic and semantic memory. It’s having something in between.
Blockchain of connected events and facts
I call it temporal-aware semantics or time-aware knowledge graphs, where we could encode the semantic fact together with the time component.I doubt that time should be the simple timestamp or the region of the two timestamps. For me, it is more a chain for facts that have a partial order and form a blockchain like a database or a partially ordered Acyclic graph of facts that are temporally connected. We could have some notion of time that is understandable to the agent and a model that allows us to order the events and focus on what the agent knows and how to order this time knowledge and create the chains of the events.
Time anchors
We may have a particular time in the chain that allows us to arrange a more concrete time for the rest of the events. But it’s still an open topic for research. The temporal semantics gets split into a couple of domains. One domain is how to add time to the knowledge graphs. We already have many different solutions. I described them in my previous articles.
Another domain is the agent's memory and how the memory of the artificial intelligence treats the time. This one, it’s much more complex. Because here, we could not operate with the simple timestamps. We need to have the representation of time that are understandable by model and understandable by the agent that will work with this model. And this one, it’s way bigger topic for the research.”

2025-05-22 05:42:27คนเรามักจะเห็นคุณค่าของสิ่งใด ส่วนใหญ่ก็ใน ๒ สถานการณ์คือ หนึ่ง ตอนที่ยังไม่ได้มา หรือ สอง ตอนที่เสียไปแล้ว
อันนี้มันเป็นโศกนาฏกรรม ที่เกิดขึ้นกับผู้คนจำนวนมาก การที่คนเรามีสิ่งดีๆ แต่ว่าเราไม่เห็นคุณค่า เพราะว่าเรามองออกไปนอกตัว ไปเห็นแต่สิ่งที่ตัวเองไม่มี อยากจะได้มา
คล้ายๆ กับเรื่อง หมาคาบเนื้อในนิทานอีสป ตอนเด็กๆ เราคงจำได้ มีหมาตัวหนึ่งคาบเนื้อมา เนื้อชิ้นใหญ่เลย มันดีใจมากแล้วมันก็วิ่งไปยังที่ที่ มันจะได้กินเนื้ออย่างมีความสุข มีช่วงหนึ่งก็ต้องเดินข้ามสะพาน มันก็ชะโงกหน้าไปมองที่ลำธารหรือลำคลอง
ก็เห็นเงาตัวเอง เงานั่นมันก็ใหญ่ แล้วมันก็พบว่าในเงานั้น เนื้อในเงามันใหญ่กว่าเนื้อที่ตัวเองคาบ มันอยากได้เนื้อก้อนนั้นมากเลย เพราะว่ามันเป็นก้อนที่ใหญ่กว่า
มันก็เลยอ้าปาก เพื่อที่จะไปงับเนื้อในเงานั้น พอมันอ้าปาก ก็ปรากฏว่าเนื้อในปาก ก็หลุดตกลงแม่น้ำ แล้วเนื้อในเงานั้นก็หายไป เป็นอันว่าหมดเลย อดทั้ง 2 อย่าง .
ฉะนั้น คนเราถ้าหากเรา กลับมาเห็นคุณค่าของสิ่งที่เรามีอยู่ เราจะมีความสุขได้ง่าย อาจจะไม่ใช่สิ่งของ อาจจะไม่ใช่ผู้คน แต่อาจจะเป็นสุขภาพของเรา
อาจจะได้แก่ ลมหายใจของเรา ที่ยังหายใจได้ปกติ รวมถึงการที่ เรายังเดินเหินไปไหนมาไหนได้ การที่เรายังมองเห็น การที่เรายังได้ยิน
หลายคนมีสิ่งนี้อยู่ในตัว แต่กลับไม่เห็นค่า และไม่รู้สึกว่าตัวเองโชคดี กลับไปมองว่า ฉันยังไม่มีโน่นยังไม่มีนี่ ไม่มีบ้าน ไม่มีรถ ไม่มีเงิน
รู้สึกว่าทุกข์ระทมเหลือเกิน
ทำไมฉันจึงลำบากแบบนี้ ทั้งที่ตัวเองก็มีสิ่งดีๆ ในตัว สุขภาพ ความปกติสุข อิสรภาพที่เดินไปไหนมาไหนได้
แต่กลับไม่เห็นค่า เพราะว่ามัวแต่ไปสนใจสิ่งที่ตัวเองยังไม่มี
ซึ่งเป็นอนาคต
ถ้าเราหันกลับมาเห็นคุณค่าของสิ่งที่เรามีอยู่ แล้วก็ไม่ไปพะวงหรือให้ความสนใจกับสิ่งที่ยังไม่มี เราจะมีความสุขได้ง่าย อันนี้คือ ความหมายหนึ่งของการทำปัจจุบันให้ดีที่สุด

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.

2024-11-21 12:05:09A state-controlled money supply can influence the development of socialist policies and practices in various ways. Although the relationship is not deterministic, state control over the money supply can contribute to a larger role of the state in the economy and facilitate the implementation of socialist ideals.
Fiscal Policy Capabilities
When the state manages the money supply, it gains the ability to implement fiscal policies that can lead to an expansion of social programs and welfare initiatives. Funding these programs by creating money can enhance the state's influence over the economy and move it closer to a socialist model. The Soviet Union, for instance, had a centralized banking system that enabled the state to fund massive industrialization and social programs, significantly expanding the state's role in the economy.
Wealth Redistribution
Controlling the money supply can also allow the state to influence economic inequality through monetary policies, effectively redistributing wealth and reducing income disparities. By implementing low-interest loans or providing financial assistance to disadvantaged groups, the state can narrow the wealth gap and promote social equality, as seen in many European welfare states.
Central Planning
A state-controlled money supply can contribute to increased central planning, as the state gains more influence over the economy. Central banks, which are state-owned or heavily influenced by the state, play a crucial role in managing the money supply and facilitating central planning. This aligns with socialist principles that advocate for a planned economy where resources are allocated according to social needs rather than market forces.
Incentives for Staff
Staff members working in state institutions responsible for managing the money supply have various incentives to keep the system going. These incentives include job security, professional expertise and reputation, political alignment, regulatory capture, institutional inertia, and legal and administrative barriers. While these factors can differ among individuals, they can collectively contribute to the persistence of a state-controlled money supply system.
In conclusion, a state-controlled money supply can facilitate the development of socialist policies and practices by enabling fiscal policies, wealth redistribution, and central planning. The staff responsible for managing the money supply have diverse incentives to maintain the system, further ensuring its continuation. However, it is essential to note that many factors influence the trajectory of an economic system, and the relationship between state control over the money supply and socialism is not inevitable.

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

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

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

2025-05-22 05:07:09CHAPTER TWENTY FIVE
“It’s over… isn’t it?” Sandra asked gently, her eyes scanning James’s expression as they stood on the balcony overlooking the city skyline. The cold breeze tousled her hair, but James remained still, his hands tucked into the pockets of his tailored suit.
“No,” James replied calmly, his gaze fixated on the horizon. “This is just the eye of the storm. The calm before the reckoning.”
Sandra stepped closer, concern etched into her features. “Mark and Helen are finished in the eyes of the public and everyone round us. The evidence is damning. The authorities have issued warrants. What more could you possibly be planning?”
James turned to face her, a half-smile playing at the edge of his lips one not born of triumph, but of determination.
“Reputation is one thing,” he said, his voice measured and resolute, “but accountability is another. I won’t stop until every lie they told, every trap they laid, and every person they corrupted is exposed. I won’t just silence them, I'll dismantle everything they built with deceit.”
Inside the boardroom, Charles, Rita, and several executives were reviewing the latest media analytics. The company’s reputation had not only recovered but skyrocketed. Investors who once hesitated were now eager, flooding JP Enterprises with new partnerships and proposals.
Rita looked up from the screen. “We’ve just surpassed our projected valuation for the quarter. The crisis gave us more publicity than a million-dollar campaign would.”
Charles chuckled under his breath. “They handed us a scandal, and we turned it into a spotlight.”
Meanwhile, in a dark corner of the city, Mark and Helen sat huddled in a private lawyer’s office. Their appearance had changed drastically; both looked worn, disheveled, stripped of the pride and arrogance they once were like a crown.
“I told you,” Mark muttered bitterly, “we shouldn’t have gone after him like that. We were greedy. And now look ruined.”
Helen clenched her fists. Her pride was still fighting, even though her kingdom had collapsed. “It’s not over. We still have connections. The law can be manipulated. If we go down, we don’t go alone.”
“And say what?” Mark snapped. “That we were outsmarted? That the man we called a street dog now owns eighty-five percent of our legacy? That he single handedly turned the world against us?”
Helen’s jaw tightened. “If there’s one thing I know about James, it’s that he never lets go of the past. And that might just be his weakness.”
But even as they plotted, they didn’t know James had already anticipated their final desperation. Back at JP Enterprises, in a high-security conference room, investigators were filing reports, financial audits, bribery trails, hacked communications all linked directly to the duo. James had ensured that every illegal move they made was documented, cross-referenced, and legally binding.
Later that evening, James stood alone in his office, the city bathed in golden twilight. He took a slow breath and whispered to himself:
“They mistook my silence for surrender. My fall for failure. But every exile sharpens a man’s edge. And now they’ll witness the blade.”
Just then, a knock came at the door.
“Come in,” he said.
It was Mrs. JP, her expression soft but proud.
“You handled yourself like a true heir,” she said, walking toward him.
James turned, emotion flickering in his eyes.
“Thank you,” he said quietly.
She reached out, holding his hand. “Your father and I… we made mistakes. We let our fear and our pride cloud your judgment. But seeing you today, the man you’ve become, I see now that everything we hoped for in a successor lives in you.”
He smiled faintly. “I didn’t do it for recognition. I did it for dignity. For every time I was humiliated, overlooked, and discarded. I wanted to prove that worth isn’t given, it's earned.”
As they stood in silence, the city lights below gleamed like stars scattered on the earth.
The evening had settled quietly over the city, and the soft hum of the wind outside was the only sound that broke the stillness of the room. James stood at the window of his office, watching the neon lights flicker to life across the skyline, each glow a reminder of his success. His gaze, however, wasn’t on the bright lights of victory, but on the darker shadows of those who had tried to ruin him.
He turned around as the door clicked open, revealing Rita, who walked in with a folder in her hands. There was something different in her posturean air of finality in the way she carried herself.
"I’ve been reviewing the report from the legal team," she began, laying the folder on his desk. "The evidence against Mark and Helen is irrefutable. Their assets are frozen, and their personal accounts are being audited. They’re on the brink of losing everything."
James nodded, his face unreadable, but inside, the weight of the moment settled over him. This was the culmination of years of effort, the battle for his honor, his family's name, and the very future of JP Enterprises. But the victory, as sweet as it was, felt hollow.
"Is that all?" he asked, his voice low.
Rita hesitated for a moment. "There’s something else. Something you need to see."
She opened the folder, revealing a series of photographs and documents of Mark and Helen in compromising positions, shaking hands with notorious figures, and receiving bribes from external business associates. The weight of their corruption was staggering. The photos captured the desperation in their eyes, the deceit in their every smile.
James glanced at the images, but there was no anger in his expression. Only an eerie calm.
"I don’t need to see this," he said quietly. "I already know everything."
Rita frowned, confused. "Then why keep going? Why dig into their past when you already have what you need?"
James leaned back in his chair, crossing his arms. "Because it's not about them anymore." He paused, allowing the gravity of his words to settle. "It’s about ensuring that no one else dares to make the same mistakes they did. No one else will ever underestimate me again."
Rita studied him carefully. There was a resolute determination in his eyes a fierce will that had carried him from the streets to the heights of power. She couldn’t help but admire his unwavering focus.
"You’ve become something entirely different," she murmured. "The man we see now... is nothing like the one who started this journey."
James met her gaze, a faint smile tugging at the corners of his lips.

2025-05-22 01:30:37ถ้าพูดถึง "เกาหลีใต้" หลายคนอาจนึกถึงซีรีส์ น้ำจิ้มเผ็ด หรือไอดอลหน้าผ่อง ๆ แต่เบื้องหลังวัฒนธรรมที่ลื่นไหลไปทั่วโลกนี้ ยังมีอาณาจักรธุรกิจขนาดมหึมาที่เป็นเหมือนเครื่องยนต์หลักผลักดันทั้งอาหาร เพลง หนัง และนวัตกรรมระดับโลก หนึ่งในนั้นคือ CJ Group ที่เริ่มต้นจากบริษัทน้ำตาลเล็ก ๆ ในปี 1953 แต่เติบโตจนกลายเป็นหนึ่งใน conglomerate หรือ "กลุ่มธุรกิจผูกเครือ" ที่ทรงอิทธิพลที่สุดของแดนโสม
คำว่า CJ ย่อมาจาก CheilJedang (แปลว่า “หมายเลขหนึ่งแห่งโลก” ในภาษาจีน-เกาหลี) ก่อตั้งโดย อี บยองชอล ผู้ก่อตั้ง Samsung Group ในช่วงเวลานั้น เกาหลีใต้กำลังฟื้นตัวจากสงครามเกาหลี และรัฐบาลส่งเสริมการพัฒนาอุตสาหกรรมภายในประเทศ เดิมเป็นหน่วยธุรกิจอาหารของกลุ่ม Samsung ในปี 1993 Cheil Jedang แยกตัวออกจาก Samsung Group และกลายเป็นบริษัทอิสระภายใต้การบริหารของ อี แจฮยอน หลานชายของอี บยองชอล แล้วขยายขอบเขตธุรกิจอย่างไม่หยุดยั้ง จากความเชี่ยวชาญใน "การหมัก" แบบดั้งเดิม พวกเขากลับกลายเป็นผู้เล่นรายใหญ่ระดับโลกในวงการ เทคโนโลยีชีวภาพ การผลิตอาหารไปจนถึงธุรกิจ บันเทิงระดับฮอลลีวูด และ โลจิสติกส์ข้ามทวีป
พูดง่าย ๆ ว่า CJ ไม่ได้แค่ส่งออกกิมจิหรือบิบิมบับ แต่พวกเขากำลังวางรากฐานของ "อนาคตแห่งอาหาร" และ "ความบันเทิงแบบไร้พรมแดน" ในเวลาเดียวกัน จนใครหลายคนถึงกับบอกว่า ถ้าอยากเข้าใจเกาหลีใต้ ก็ต้องเริ่มจากเข้าใจ CJ Group เสียก่อน
แล้วในเครือข่ายของ CJ Group มีธุรกิจอะไรบ้างที่น่าสนใจ และแบรนด์ไหนที่เราคุ้นเคยแบบไม่รู้ตัว ไปดูกันเลย
- ธุรกิจอาหารและบริการอาหาร (Food & Food Services)

ธุรกิจบันเทิงและสื่อ (Entertainment & Media) อันนี้ยิ่งใหญ่ระดับโลกมากๆ หลายคนคงจำได้กับ ภาพยนตร์เอเชียแรกกับรางวัลออสการ์ Parasite
- CJ ENM บริษัทผลิตและจัดจำหน่ายเนื้อหาบันเทิงที่มีชื่อเสียงระดับโลก มีผลงานเด่น ได้แก่ Crash Landing on You ซีรีส์ที่ได้รับความนิยมอย่างสูง Parasite ภาพยนตร์ที่ได้รับรางวัลออสการ์
- CJ CGV เครือโรงภาพยนตร์มัลติเพล็กซ์ที่มีสาขาทั่วโลก
CJ Group ขยายธุรกิจไปยังต่างประเทศ เช่น การเข้าซื้อกิจการ Schwan's Company ในสหรัฐอเมริกา และการเปิดสาขา CGV ในหลายประเทศ นอกจากนี้ CJ ยังมีบทบาทสำคัญในการเผยแพร่วัฒนธรรมเกาหลีสู่ระดับโลกผ่าน KCON และการผลิตเนื้อหาบันเทิงที่ได้รับความนิยมในต่างประเทศด้วยครับ
จะเห็นได้ว่า เครือข่ายของ CJ นั้นยิ่งใหญ่มากๆเลย ทีนี้มีเรื่องน่าสนใจตรงนี้ครับ
ในช่วงปี 2013–2016 CJ Group โดยเฉพาะฝ่ายสื่อบันเทิงอย่าง CJ ENM ต้องเผชิญกับแรงกดดันจากรัฐบาลของประธานาธิบดี พัค กึนฮเย เหตุการณ์สำคัญคือการที่ อี มีคยอง (Miky Lee) รองประธาน CJ และผู้มีบทบาทสำคัญในการขับเคลื่อนธุรกิจบันเทิงระดับโลก ถูกกดดันให้ลาออกจากตำแหน่ง รายงานระบุว่า ทำเนียบประธานาธิบดีไม่พอใจเนื้อหาสื่อบางรายการของ CJ ที่มีลักษณะเสียดสีหรือวิพากษ์วิจารณ์รัฐบาล เช่น รายการ SNL Korea ที่ล้อเลียนพัค กึนฮเย ผ่านตัวละคร Teletubbies
ภายใต้แรงกดดันนี้ CJ มีการปรับเปลี่ยนเนื้อหาสื่อ โดยลดการนำเสนอเนื้อหาที่อาจขัดแย้งกับรัฐบาล และหันไปผลิตภาพยนตร์ที่สอดคล้องกับนโยบายของรัฐ เช่น ภาพยนตร์เรื่อง Ode to My Father (2014) ที่สะท้อนความรักชาติและการพัฒนาเศรษฐกิจในยุคของพัค ชุงฮี บิดาของพัค กึนฮเย ภาพยนตร์เรื่องนี้ได้รับการสนับสนุนจากรัฐบาลและถูกมองว่าเป็น "ภาพยนตร์เพื่อสุขภาพ" ที่ส่งเสริมความภาคภูมิใจในชาติ แน่นอนว่าแค้นฝังหุ่นมันยังไม่หายไปไหนครับ
เมื่อเกิดการเปิดโปง "บัญชีดำ" (Blacklist) ของรัฐบาลพัค กึนฮเย ที่มีการจำกัดสิทธิเสรีภาพของศิลปินและผู้ผลิตสื่อที่วิพากษ์วิจารณ์รัฐบาล ทำให้เกิดกระแสต่อต้านอย่างรุนแรงในสังคมเกาหลี. ในปี 2016 ซน กยองชิก ประธาน CJ ได้ให้การต่อศาลว่า มีแรงกดดันจากรัฐบาลให้ อี มีคยอง หลีกเลี่ยงการมีบทบาทในบริษัท เหตุการณ์นี้เป็นส่วนหนึ่งของการเปิดโปงคดีทุจริตของพัค กึนฮเย ซึ่งนำไปสู่การประท้วงครั้งใหญ่และการถอดถอนประธานาธิบดีในปี 2017
หลังจากการเปลี่ยนแปลงทางการเมือง CJ Group ได้กลับมามีบทบาทอย่างเต็มที่ในวงการบันเทิงอีกครั้ง อี มีคยอง กลับมาดำรงตำแหน่งและมีบทบาทสำคัญในการผลักดันภาพยนตร์เรื่อง Parasite (2019) ซึ่งได้รับรางวัลออสการ์และยกระดับภาพลักษณ์ของ CJ ในระดับโลก ซึ่งถ้าใครได้ดูหนังเรื่องนั้นแล้วรู้เรื่องราวเบื้องหลังนี้จะเข้าใจเนื้อหาได้อย่างลึกซึ้งขึ้นไปอีกเลยครับ การนำเสนอเรื่องราวนี้ถือเป็นการวิพากษ์วิจารณ์สังคมและระบบทุนนิยมอย่างชัดเจน ซึ่งแตกต่างจากแนวทางที่ CJ เคยถูกกดดันให้ปฏิบัติตามในยุคของพัค กึนฮเย อย่างสิ้นเชิง
อย่าเพิ่งไปสะใจกับเนื้อหา ให้มองว่า "เขาทำอะไรได้บ้าง" นี่คือประเด็นสำคัญครับ #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

2024-11-17 10:48:56This week's functional 3d print is the "Dino Clip".
Dino Clip
I printed it some years ago for my son, so he would have his own clip for cereal bags.
Now it is used to hold a bag of dog food close.
The design by "Sneaks" is a so called "print in place". This means that the whole clip with moving parts is printed in one part, without the need for assembly after the print.
The clip is very strong, and I would print it again if I need a "heavy duty" clip for more rigid or big bags. Link to the file at Printables

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

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

2025-05-21 22:13:47The global population has been rising rapidly for the past two centuries when compared to historical trends. Fifty years ago, that trend seemed set to continue, and there was a lot of concern around the issue of overpopulation. But if you haven’t been living under a rock, you’ll know that while the population is still rising, that trend now seems set to reverse this century, and there’s every indication population could decline precipitously over the next two centuries.
Demographics is a field where predictions about the future are much more reliable than in most scientific fields. That’s because future population trends are “baked in” decades in advance. If you want to know how many fifty-year-olds there will be in forty years, all you have to do is count the ten-year-olds today and allow for mortality rates. That maximum was already determined by the number of births ten years ago, and absolutely nothing can change that now. The average person doesn’t think that through when they look at population trends. You hear a lot of “oh we just need to do more of x to help the declining birthrate” without an acknowledgement that future populations in a given cohort are already fixed by the number of births that already occurred.
As you can see, global birthrates have already declined close to the 2.3 replacement level, with some regions ahead of others, but all on the same trajectory with no region moving against the trend. I’m not going to speculate on the reasons for this, or even whether it’s a good or bad thing. Instead I’m going to make some observations about outcomes this trend could cause economically, and why. Like most macro issues, an individual can’t do anything to change the global landscape personally, but knowing what that landscape might look like is essential to avoiding fallout from trends outside your control.
The Resource Pie
Thomas Malthus popularized the concern about overpopulation with his 1798 book An Essay on the Principle of Population. The basic premise of the book was that population could grow and consume all the available resources, leading to mass poverty, starvation, disease, and population collapse. We can say in hindsight that this was incorrect, given that the global population has increased from less than a billion to over eight billion since then, and the apocalypse Malthus predicted hasn’t materialized. Exactly the opposite, in fact. The global standard of living has risen to levels Malthus couldn’t have imagined, much less predicted.
So where did Malthus go wrong? His hypothesis seems reasonable enough, and we do see a similar trend in certain animal populations. The base assumption Malthus got wrong was to assume resources are a finite, limiting factor to the human population. That at some point certain resources would be totally consumed, and that would be it. He treated it like a pie with a lot of slices, but still a finite number, and assumed that if the population kept rising, eventually every slice would be consumed and there would be no pie left for future generations. That turns out to be completely wrong.
Of course, the earth is finite at some abstract level. The number of atoms could theoretically be counted and quantified. But on a practical level, do humans exhaust the earth’s resources? I’d point to an article from Yale Scientific titled Has the Earth Run out of any Natural Resources? To quote,
> However, despite what doomsday predictions may suggest, the Earth has not run out of any resources nor is it likely that it will run out of any in the near future. > > In fact, resources are becoming more abundant. Though this may seem puzzling, it does not mean that the actual quantity of resources in the Earth’s crust is increasing but rather that the amount available for our use is constantly growing due to technological innovations. According to the U.S. Geological Survey, the only resource we have exhausted is cryolite, a mineral used in pesticides and aluminum processing. However, that is not to say every bit of it has been mined away; rather, producing it synthetically is much more cost efficient than mining the existing reserves at its current value.
As it happens, we don’t run out of resources. Instead, we become better at finding, extracting, and efficiently utilizing resources, which means that in practical terms resources become more abundant, not less. In other words, the pie grows faster than we can eat it.
So is there any resource that actually limits human potential? I think there is, and history would suggest that resource is human ingenuity and effort. The more people are thinking about and working on a problem, the more solutions we find and build to solve it. That means not only does the pie grow faster than we can eat it, but the more people there are, the faster the pie grows. Of course that assumes everyone eating pie is also working to grow the pie, but that’s a separate issue for now.
Productivity and Division of Labor
Why does having more people lead to more productivity? A big part of it comes down to division of labor and specialization. The best way to get really good at something is to do more of it. In a small community, doing just one thing simply isn’t possible. Everyone has to be somewhat of a generalist in order to survive. But with a larger population, being a specialist becomes possible. In fact, that’s the purpose of money, as I explained here.
nostr:naddr1qvzqqqr4gupzp0rve5f6xtu56djkfkkg7ktr5rtfckpun95rgxaa7futy86npx8yqq247t2dvet9q4tsg4qng36lxe6kc4nftayyy89kua2
The more specialized an economy becomes, the more efficient it can be. There are big economies of scale in almost every task or process. So for example, if a single person tried to build a car from scratch, it would be extremely difficult and take a very long time. However, if you have a thousand people building a car, each doing a specific job, they can become very good at doing that specific job and do it much faster. And then you can move that process to a factory, and build machines to do specific jobs, and add even more efficiency.
But that only works if you’re building more than one car. It doesn’t make sense to build a huge factory full of specialized equipment that takes lots of time and effort to design and manufacture, and then only build one car. You need to sell thousands of cars, maybe even millions of cars, to pay off that initial investment. So division of labor and specialization relies on large populations in two different ways. First, you need a large population to have enough people to specialize in each task. But second and just as importantly, you need a large population of buyers for the finished product. You need a big market in order to make mass production economical.
Think of a computer or smartphone. It takes thousands of specialized processes, thousands of complex parts, and millions of people doing specialized jobs to extract the raw materials, process them, and assemble them into a piece of electronic hardware. And electronics are relatively expensive anyway. Imagine how impossible it would be to manufacture electronics economically, if the market demand wasn’t literally in the billions of units.
Stairs Up, Elevator Down
We’ve seen exponential increases in productivity over the past few centuries, resulting in higher living standards even as population exploded. Now, facing the prospect of a drastic trend reversal, what will happen to productivity and living standards? The typical sentiment seems to be “well, there are a lot of people already competing for resources, so if population does decline, that will just reduce the competition and leave a bigger slice of pie for each person, so we’ll all be getting wealthier as a result of population decline.”
This seems reasonable at first glance. Surely dividing the economic pie into fewer slices means a bigger slice for everyone, right? But remember, more specialization and division of labor is what made the pie as big as it is to begin with. And specialization depends on large populations for both the supply of specialized labor, and the demand for finished goods. Can complex supply chains and mass production withstand population reduction intact? I don’t think the answer is clear.
The idea that it will all be okay, and we’ll get wealthier as population falls, is based on some faulty assumptions. It assumes that wealth is basically some fixed inventory of “things” that exist, and it’s all a matter of distribution. That’s typical Marxist thinking, similar to the reasoning behind “tax the rich” and other utopian wealth transfer schemes.
The reality is, wealth is a dynamic concept with strong network effects. For example, a grocery store in a large city can be a valuable asset with a large potential income stream. The same store in a small village with a declining population can be an unprofitable and effectively worthless liability.
Even something as permanent as a house is very susceptible to network effects. If you currently live in an area where housing is scarce and expensive, you might think a declining population would be the perfect solution to high housing costs. However, if you look at a place that’s already facing the beginnings of a population decline, you’ll see it’s not actually that simple. Japan, for example, is already facing an aging and declining population. And sure enough, you can get a house in Japan for free, or basically free. Sounds amazing, right? Not really.
If you check out the reason houses are given away in Japan, you’ll find a depressing reality. Most of the free houses are in rural areas or villages where the population is declining, often to the point that the village becomes uninhabited and abandoned. It’s so bad that in 2018, 13.6% of houses in Japan were vacant. Why do villages become uninhabited? Well, it turns out that a certain population level is necessary to support the services and businesses people need. When the population falls too low, specialized businesses can no longer operated profitably. It’s the exact issue we discussed with division of labor and the need for a high population to provide a market for the specialist to survive. As the local stores, entertainment venues, and businesses close, and skilled tradesmen move away to larger population centers with more customers, living in the village becomes difficult and depressing, if not impossible. So at a certain critical level, a village that’s too isolated will reach a tipping point where everyone leaves as fast as possible. And it turns out that an abandoned house in a remote village or rural area without any nearby services and businesses is worth… nothing. Nobody wants to live there, nobody wants to spend the money to maintain the house, nobody wants to pay the taxes needed to maintain the utilities the town relied on. So they try to give the houses away to anyone who agrees to live there, often without much success.
So on a local level, population might rise gradually over time, but when that process reverses and population declines to a certain level, it can collapse rather quickly from there.
I expect the same incentives to play out on a larger scale as well. Complex supply chains and extreme specialization lead to massive productivity. But there’s also a downside, which is the fragility of the system. Specialization might mean one shop can make all the widgets needed for a specific application, for the whole globe. That’s great while it lasts, but what happens when the owner of that shop retires with his lifetime of knowledge and experience? Will there be someone equally capable ready to fill his shoes? Hopefully… But spread that problem out across the global economy, and cracks start to appear. A specialized part is unavailable. So a machine that relies on that part breaks down and can’t be repaired. So a new machine needs to be built, which is a big expense that drives up costs and prices. And with a falling population, demand goes down. Now businesses are spending more to make fewer items, so they have to raise prices to stay profitable. Now fewer people can afford the item, so demand falls even further. Eventually the business is forced to close, and other industries that relied on the items they produced are crippled. Things become more expensive, or unavailable at any price. Living standards fall. What was a stairway up becomes an elevator down.
Hope, From the Parasite Class?
All that being said, I’m not completely pessimistic about the future. I think the potential for an acceptable outcome exists.
I see two broad groups of people in the economy; producers, and parasites. One thing the increasing productivity has done is made it easier than ever to survive. Food is plentiful globally, the only issues are with distribution. Medical advances save countless lives. Everything is more abundant than ever before. All that has led to a very “soft” economic reality. There’s a lot of non-essential production, which means a lot of wealth can be redistributed to people who contribute nothing, and if it’s done carefully, most people won’t even notice. And that is exactly what has happened, in spades.
There are welfare programs of every type and description, and handouts to people for every reason imaginable. It’s never been easier to survive without lifting a finger. So millions of able-bodied men choose to do just that.
Besides the voluntarily idle, the economy is full of “bullshit jobs.” Shoutout to David Graeber’s book with that title. (It’s an excellent book and one I would highly recommend, even though the author was a Marxist and his conclusions are completely wrong.) A 2015 British poll asked people, “Does your job make a meaningful contribution to the world?” Only 50% said yes, while 37% said no and 13% were uncertain.
This won’t be a surprise to anyone who’s operated a business, or even worked in the private sector in general. There are three types of jobs; jobs that accomplish something productive, jobs that accomplish nothing of value, and jobs that actually hinder people trying to accomplish something productive. The number of jobs in the last two categories has grown massively over the years. This would include a lot of unnecessary administrative jobs, burdensome regulatory jobs, useless DEI and HR jobs, a large percentage of public sector jobs, most of the military-industrial complex, and the list is endless. All these jobs accomplish nothing worthwhile at best, and actively discourage those who are trying to accomplish something at worst.
Even among jobs that do accomplish some useful purpose, the amount of time spent actually doing the job continues to decline. According to a 2016 poll, American office workers spent only 39% of their workday actually doing their primary task. The other 61% was largely wasted on unproductive administrative tasks and meetings, answering emails, and just simply wasting time.
I could go on, but the point is, there’s a lot of slack in the economy. We’ve become so productive that the number of people actually doing the work to keep everyone fed, clothed, and cared for is only a small percentage of the population. In one sense, that’s a cause for optimism. The population could decline a lot, and we’d still have enough bodies to man the economic engine, as it were.
Aging
The thing with population decline, though, is nobody gets to choose who goes first. Not unless you’re a psychopathic dictator. So populations get old, then they get small. This means that the number of dependents in the economy rises naturally. Once people retire, they still need someone to grow the food, keep the lights on, and provide the medical care. And it doesn’t matter how much money the retirees have saved, either. Money is just a claim on wealth. The goods and services actually have to be provided by someone, and if that someone was never born, all the money in the world won’t change anything.
And the aging occurs on top of all the people already taking from the economy without contributing anything of value. So that seems like a big problem.
Currently, wealth redistribution happens through a combination of direct taxes, indirect taxation through deficit spending, and the whole gamut of games that happen when banks create credit/debt money by making loans. In a lot of cases, it’s very indirect and difficult to pin down. For example, someone has a “job” in a government office, enforcing pointless regulations that actually hinder someone in the private sector from producing something useful. Their paycheck comes from the government, so a combination of taxes on productive people, and deficit spending, which is also a tax on productive people. But they “have a job,” so who’s going to question their contribution to society? On the other hand, it could be a banker or hedge fund manager. They might be pulling in a massive salary, but at the core all they’re really doing is finding creative financial ways to transfer wealth from productive people to themselves, without contributing anything of value.
You’ll notice a common theme if you think about this problem deeply. Most of the wealth transfer that supports the unproductive, whether that’s welfare recipients, retirees, bureaucrats, corporate middle managers, or weapons manufacturers, is only possible through expanding the money supply. There’s a limit to how much direct taxation the productive will bear while the option to collect welfare exists. At a certain point, people conclude that working hard every day isn’t worth it, when taxes take so much of their wages that they could make almost as much without working at all. So the balance of what it takes to support the dependent class has to come indirectly, through new money creation.
As long as the declining population happens under the existing monetary system, the future looks bleak. There’s no limit to how much money creation and inflation the parasite class will use in an attempt to avoid work. They’ll continue to suck the productive class dry until the workers give up in disgust, and the currency collapses into hyperinflation. And you can’t run a complex economy without functional money, so productivity inevitably collapses with the currency.
The optimistic view is that we don’t have to continue supporting the failed credit/debt monetary system. It’s hurting productivity, messing up incentives, and contributing to increasing wealth inequality and lower living standards for the middle class. If we walk away from that system and adopt a hard money standard, the possibility of inflationary wealth redistribution vanishes. The welfare and warfare programs have to be slashed. The parasite class is forced to get busy, or starve. In that scenario, the declining population of workers can be offset by a massive shift away from “bullshit jobs” and into actual productive work.
While that might not be a permanent solution to declining population, it would at least give us time to find a real solution, without having our complex economy collapse and send our living standards back to the 17th century.
It’s a complex issue with many possible outcomes, but I think a close look at the effects of the monetary system on productivity shows one obvious problem that will make the situation worse than necessary. Moving to a better monetary system and creating incentives for productivity would do a lot to reduce the economic impacts of a declining population.

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

Jerusalem, The Old City, circa 2014. Israel.

2025-05-16 05:38:28LegoGPT generates a LEGO structure from a user-provided text prompt in an end-to-end manner. Notably, our generated LEGO structure is physically stable and buildable.
Lego is something most of us knows. This is a opportuity to ask where is our creativity going? From the art of crafting figures to building blocks following our need and desires to have a machine thinking and building following step-by-step instructions to achieve an isolated goal.
Is the creative act then in the question itself, not anymore in the crafting? Are we just delegating the solution of problems, the thinking of how to respond to questions, to machines? Would it be different if delegated to other people?

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

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

2025-03-22 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:

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

2025-05-21 19:28:38Phobia and temperament are two distinct concepts in psychology:
Phobia 1. Specific fear or anxiety: Phobias involve intense, irrational fears or anxieties towards specific objects, situations, or activities. 2. Avoidance behavior: People with phobias often exhibit avoidance behaviors to escape the feared stimulus. 3. Impact on daily life: Phobias can significantly impact an individual's daily life, causing distress and impairment.
Temperament 1. Personality traits: Temperament refers to an individual's inherent personality traits, including emotional reactivity, mood, and behavioral tendencies. 2. Stable patterns: Temperament is relatively stable across situations and over time. 3. Influence on behavior: Temperament influences an individual's behavior, interactions, and responses to various situations.
Key differences 1. Specificity: Phobias are specific to certain objects or situations, while temperament is a broader personality trait. 2. Focus: Phobias focus on fear or anxiety, whereas temperament encompasses a range of personality characteristics. 3. Impact: Phobias can have a significant impact on daily life, while temperament can shape an individual's overall behavior and interactions.
Comparison 1. Both influence behavior: Both phobias and temperament can influence an individual's behavior and responses to situations. 2. Both can be shaped: Both phobias and temperament can be shaped by a combination of genetic and environmental factors.
Understanding the differences and similarities between phobias and temperament can provide valuable insights into human behavior and psychological processes.

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

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

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

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.

@ a367f9eb:0633efea
2024-11-05 08:48:41Last week, an investigation by Reuters revealed that Chinese researchers have been using open-source AI tools to build nefarious-sounding models that may have some military application.
The reporting purports that adversaries in the Chinese Communist Party and its military wing are taking advantage of the liberal software licensing of American innovations in the AI space, which could someday have capabilities to presumably harm the United States.
In a June paper reviewed by Reuters, six Chinese researchers from three institutions, including two under the People’s Liberation Army’s (PLA) leading research body, the Academy of Military Science (AMS), detailed how they had used an early version of Meta’s Llama as a base for what it calls “ChatBIT”.
The researchers used an earlier Llama 13B large language model (LLM) from Meta, incorporating their own parameters to construct a military-focused AI tool to gather and process intelligence, and offer accurate and reliable information for operational decision-making.
While I’m doubtful that today’s existing chatbot-like tools will be the ultimate battlefield for a new geopolitical war (queue up the computer-simulated war from the Star Trek episode “A Taste of Armageddon“), this recent exposé requires us to revisit why large language models are released as open-source code in the first place.
Added to that, should it matter that an adversary is having a poke around and may ultimately use them for some purpose we may not like, whether that be China, Russia, North Korea, or Iran?
The number of open-source AI LLMs continues to grow each day, with projects like Vicuna, LLaMA, BLOOMB, Falcon, and Mistral available for download. In fact, there are over one million open-source LLMs available as of writing this post. With some decent hardware, every global citizen can download these codebases and run them on their computer.
With regard to this specific story, we could assume it to be a selective leak by a competitor of Meta which created the LLaMA model, intended to harm its reputation among those with cybersecurity and national security credentials. There are potentially trillions of dollars on the line.
Or it could be the revelation of something more sinister happening in the military-sponsored labs of Chinese hackers who have already been caught attacking American infrastructure, data, and yes, your credit history?
As consumer advocates who believe in the necessity of liberal democracies to safeguard our liberties against authoritarianism, we should absolutely remain skeptical when it comes to the communist regime in Beijing. We’ve written as much many times.
At the same time, however, we should not subrogate our own critical thinking and principles because it suits a convenient narrative.
Consumers of all stripes deserve technological freedom, and innovators should be free to provide that to us. And open-source software has provided the very foundations for all of this.
Open-source matters When we discuss open-source software and code, what we’re really talking about is the ability for people other than the creators to use it.
The various licensing schemes – ranging from GNU General Public License (GPL) to the MIT License and various public domain classifications – determine whether other people can use the code, edit it to their liking, and run it on their machine. Some licenses even allow you to monetize the modifications you’ve made.
While many different types of software will be fully licensed and made proprietary, restricting or even penalizing those who attempt to use it on their own, many developers have created software intended to be released to the public. This allows multiple contributors to add to the codebase and to make changes to improve it for public benefit.
Open-source software matters because anyone, anywhere can download and run the code on their own. They can also modify it, edit it, and tailor it to their specific need. The code is intended to be shared and built upon not because of some altruistic belief, but rather to make it accessible for everyone and create a broad base. This is how we create standards for technologies that provide the ground floor for further tinkering to deliver value to consumers.
Open-source libraries create the building blocks that decrease the hassle and cost of building a new web platform, smartphone, or even a computer language. They distribute common code that can be built upon, assuring interoperability and setting standards for all of our devices and technologies to talk to each other.
I am myself a proponent of open-source software. The server I run in my home has dozens of dockerized applications sourced directly from open-source contributors on GitHub and DockerHub. When there are versions or adaptations that I don’t like, I can pick and choose which I prefer. I can even make comments or add edits if I’ve found a better way for them to run.
Whether you know it or not, many of you run the Linux operating system as the base for your Macbook or any other computer and use all kinds of web tools that have active repositories forked or modified by open-source contributors online. This code is auditable by everyone and can be scrutinized or reviewed by whoever wants to (even AI bots).
This is the same software that runs your airlines, powers the farms that deliver your food, and supports the entire global monetary system. The code of the first decentralized cryptocurrency Bitcoin is also open-source, which has allowed thousands of copycat protocols that have revolutionized how we view money.
You know what else is open-source and available for everyone to use, modify, and build upon?
PHP, Mozilla Firefox, LibreOffice, MySQL, Python, Git, Docker, and WordPress. All protocols and languages that power the web. Friend or foe alike, anyone can download these pieces of software and run them how they see fit.
Open-source code is speech, and it is knowledge.
We build upon it to make information and technology accessible. Attempts to curb open-source, therefore, amount to restricting speech and knowledge.
Open-source is for your friends, and enemies In the context of Artificial Intelligence, many different developers and companies have chosen to take their large language models and make them available via an open-source license.
At this very moment, you can click on over to Hugging Face, download an AI model, and build a chatbot or scripting machine suited to your needs. All for free (as long as you have the power and bandwidth).
Thousands of companies in the AI sector are doing this at this very moment, discovering ways of building on top of open-source models to develop new apps, tools, and services to offer to companies and individuals. It’s how many different applications are coming to life and thousands more jobs are being created.
We know this can be useful to friends, but what about enemies?
As the AI wars heat up between liberal democracies like the US, the UK, and (sluggishly) the European Union, we know that authoritarian adversaries like the CCP and Russia are building their own applications.
The fear that China will use open-source US models to create some kind of military application is a clear and present danger for many political and national security researchers, as well as politicians.
A bipartisan group of US House lawmakers want to put export controls on AI models, as well as block foreign access to US cloud servers that may be hosting AI software.
If this seems familiar, we should also remember that the US government once classified cryptography and encryption as “munitions” that could not be exported to other countries (see The Crypto Wars). Many of the arguments we hear today were invoked by some of the same people as back then.
Now, encryption protocols are the gold standard for many different banking and web services, messaging, and all kinds of electronic communication. We expect our friends to use it, and our foes as well. Because code is knowledge and speech, we know how to evaluate it and respond if we need to.
Regardless of who uses open-source AI, this is how we should view it today. These are merely tools that people will use for good or ill. It’s up to governments to determine how best to stop illiberal or nefarious uses that harm us, rather than try to outlaw or restrict building of free and open software in the first place.
Limiting open-source threatens our own advancement If we set out to restrict and limit our ability to create and share open-source code, no matter who uses it, that would be tantamount to imposing censorship. There must be another way.
If there is a “Hundred Year Marathon” between the United States and liberal democracies on one side and autocracies like the Chinese Communist Party on the other, this is not something that will be won or lost based on software licenses. We need as much competition as possible.
The Chinese military has been building up its capabilities with trillions of dollars’ worth of investments that span far beyond AI chatbots and skip logic protocols.
The theft of intellectual property at factories in Shenzhen, or in US courts by third-party litigation funding coming from China, is very real and will have serious economic consequences. It may even change the balance of power if our economies and countries turn to war footing.
But these are separate issues from the ability of free people to create and share open-source code which we can all benefit from. In fact, if we want to continue our way our life and continue to add to global productivity and growth, it’s demanded that we defend open-source.
If liberal democracies want to compete with our global adversaries, it will not be done by reducing the freedoms of citizens in our own countries.
Last week, an investigation by Reuters revealed that Chinese researchers have been using open-source AI tools to build nefarious-sounding models that may have some military application.
The reporting purports that adversaries in the Chinese Communist Party and its military wing are taking advantage of the liberal software licensing of American innovations in the AI space, which could someday have capabilities to presumably harm the United States.
In a June paper reviewed by Reuters, six Chinese researchers from three institutions, including two under the People’s Liberation Army’s (PLA) leading research body, the Academy of Military Science (AMS), detailed how they had used an early version of Meta’s Llama as a base for what it calls “ChatBIT”.
The researchers used an earlier Llama 13B large language model (LLM) from Meta, incorporating their own parameters to construct a military-focused AI tool to gather and process intelligence, and offer accurate and reliable information for operational decision-making.
While I’m doubtful that today’s existing chatbot-like tools will be the ultimate battlefield for a new geopolitical war (queue up the computer-simulated war from the Star Trek episode “A Taste of Armageddon“), this recent exposé requires us to revisit why large language models are released as open-source code in the first place.
Added to that, should it matter that an adversary is having a poke around and may ultimately use them for some purpose we may not like, whether that be China, Russia, North Korea, or Iran?
The number of open-source AI LLMs continues to grow each day, with projects like Vicuna, LLaMA, BLOOMB, Falcon, and Mistral available for download. In fact, there are over one million open-source LLMs available as of writing this post. With some decent hardware, every global citizen can download these codebases and run them on their computer.
With regard to this specific story, we could assume it to be a selective leak by a competitor of Meta which created the LLaMA model, intended to harm its reputation among those with cybersecurity and national security credentials. There are potentially trillions of dollars on the line.
Or it could be the revelation of something more sinister happening in the military-sponsored labs of Chinese hackers who have already been caught attacking American infrastructure, data, and yes, your credit history?
As consumer advocates who believe in the necessity of liberal democracies to safeguard our liberties against authoritarianism, we should absolutely remain skeptical when it comes to the communist regime in Beijing. We’ve written as much many times.
At the same time, however, we should not subrogate our own critical thinking and principles because it suits a convenient narrative.
Consumers of all stripes deserve technological freedom, and innovators should be free to provide that to us. And open-source software has provided the very foundations for all of this.
Open-source matters
When we discuss open-source software and code, what we’re really talking about is the ability for people other than the creators to use it.
The various licensing schemes – ranging from GNU General Public License (GPL) to the MIT License and various public domain classifications – determine whether other people can use the code, edit it to their liking, and run it on their machine. Some licenses even allow you to monetize the modifications you’ve made.
While many different types of software will be fully licensed and made proprietary, restricting or even penalizing those who attempt to use it on their own, many developers have created software intended to be released to the public. This allows multiple contributors to add to the codebase and to make changes to improve it for public benefit.
Open-source software matters because anyone, anywhere can download and run the code on their own. They can also modify it, edit it, and tailor it to their specific need. The code is intended to be shared and built upon not because of some altruistic belief, but rather to make it accessible for everyone and create a broad base. This is how we create standards for technologies that provide the ground floor for further tinkering to deliver value to consumers.
Open-source libraries create the building blocks that decrease the hassle and cost of building a new web platform, smartphone, or even a computer language. They distribute common code that can be built upon, assuring interoperability and setting standards for all of our devices and technologies to talk to each other.
