2025-04-15 11:03:15Prelude
I wrote this post differently than any of my others. It started with a discussion with AI on an OPSec-inspired review of separation of powers, and evolved into quite an exciting debate! I asked Grok to write up a summary in my overall writing style, which it got pretty well. I've decided to post it exactly as-is. Ultimately, I think there are two solid ideas driving my stance here:
- Perfect is the enemy of the good
- Failure is the crucible of success
Beyond that, just some hard-core belief in freedom, separation of powers, and operating from self-interest.
Intro
Alright, buckle up. I’ve been chewing on this idea for a while, and it’s time to spit it out. Let’s look at the U.S. government like I’d look at a codebase under a cybersecurity audit—OPSEC style, no fluff. Forget the endless debates about what politicians should do. That’s noise. I want to talk about what they can do, the raw powers baked into the system, and why we should stop pretending those powers are sacred. If there’s a hole, either patch it or exploit it. No half-measures. And yeah, I’m okay if the whole thing crashes a bit—failure’s a feature, not a bug.
The Filibuster: A Security Rule with No Teeth
You ever see a firewall rule that’s more theater than protection? That’s the Senate filibuster. Everyone acts like it’s this untouchable guardian of democracy, but here’s the deal: a simple majority can torch it any day. It’s not a law; it’s a Senate preference, like choosing tabs over spaces. When people call killing it the “nuclear option,” I roll my eyes. Nuclear? It’s a button labeled “press me.” If a party wants it gone, they’ll do it. So why the dance?
I say stop playing games. Get rid of the filibuster. If you’re one of those folks who thinks it’s the only thing saving us from tyranny, fine—push for a constitutional amendment to lock it in. That’s a real patch, not a Post-it note. Until then, it’s just a vulnerability begging to be exploited. Every time a party threatens to nuke it, they’re admitting it’s not essential. So let’s stop pretending and move on.
Supreme Court Packing: Because Nine’s Just a Number
Here’s another fun one: the Supreme Court. Nine justices, right? Sounds official. Except it’s not. The Constitution doesn’t say nine—it’s silent on the number. Congress could pass a law tomorrow to make it 15, 20, or 42 (hitchhiker’s reference, anyone?). Packing the court is always on the table, and both sides know it. It’s like a root exploit just sitting there, waiting for someone to log in.
So why not call the bluff? If you’re in power—say, Trump’s back in the game—say, “I’m packing the court unless we amend the Constitution to fix it at nine.” Force the issue. No more shadowboxing. And honestly? The court’s got way too much power anyway. It’s not supposed to be a super-legislature, but here we are, with justices’ ideologies driving the bus. That’s a bug, not a feature. If the court weren’t such a kingmaker, packing it wouldn’t even matter. Maybe we should be talking about clipping its wings instead of just its size.
The Executive Should Go Full Klingon
Let’s talk presidents. I’m not saying they should wear Klingon armor and start shouting “Qapla’!”—though, let’s be real, that’d be awesome. I’m saying the executive should use every scrap of power the Constitution hands them. Enforce the laws you agree with, sideline the ones you don’t. If Congress doesn’t like it, they’ve got tools: pass new laws, override vetoes, or—here’s the big one—cut the budget. That’s not chaos; that’s the system working as designed.
Right now, the real problem isn’t the president overreaching; it’s the bureaucracy. It’s like a daemon running in the background, eating CPU and ignoring the user. The president’s supposed to be the one steering, but the administrative state’s got its own agenda. Let the executive flex, push the limits, and force Congress to check it. Norms? Pfft. The Constitution’s the spec sheet—stick to it.
Let the System Crash
Here’s where I get a little spicy: I’m totally fine if the government grinds to a halt. Deadlock isn’t a disaster; it’s a feature. If the branches can’t agree, let the president veto, let Congress starve the budget, let enforcement stall. Don’t tell me about “essential services.” Nothing’s so critical it can’t take a breather. Shutdowns force everyone to the table—debate, compromise, or expose who’s dropping the ball. If the public loses trust? Good. They’ll vote out the clowns or live with the circus they elected.
Think of it like a server crash. Sometimes you need a hard reboot to clear the cruft. If voters keep picking the same bad admins, well, the country gets what it deserves. Failure’s the best teacher—way better than limping along on autopilot.
States Are the Real MVPs
If the feds fumble, states step up. Right now, states act like junior devs waiting for the lead engineer to sign off. Why? Federal money. It’s a leash, and it’s tight. Cut that cash, and states will remember they’re autonomous. Some will shine, others will tank—looking at you, California. And I’m okay with that. Let people flee to better-run states. No bailouts, no excuses. States are like competing startups: the good ones thrive, the bad ones pivot or die.
Could it get uneven? Sure. Some states might turn into sci-fi utopias while others look like a post-apocalyptic vidya game. That’s the point—competition sorts it out. Citizens can move, markets adjust, and failure’s a signal to fix your act.
Chaos Isn’t the Enemy
Yeah, this sounds messy. States ignoring federal law, external threats poking at our seams, maybe even a constitutional crisis. I’m not scared. The Supreme Court’s there to referee interstate fights, and Congress sets the rules for state-to-state play. But if it all falls apart? Still cool. States can sort it without a babysitter—it’ll be ugly, but freedom’s worth it. External enemies? They’ll either unify us or break us. If we can’t rally, we don’t deserve the win.
Centralizing power to avoid this is like rewriting your app in a single thread to prevent race conditions—sure, it’s simpler, but you’re begging for a deadlock. Decentralized chaos lets states experiment, lets people escape, lets markets breathe. States competing to cut regulations to attract businesses? That’s a race to the bottom for red tape, but a race to the top for innovation—workers might gripe, but they’ll push back, and the tension’s healthy. Bring it—let the cage match play out. The Constitution’s checks are enough if we stop coddling the system.
Why This Matters
I’m not pitching a utopia. I’m pitching a stress test. The U.S. isn’t a fragile porcelain doll; it’s a rugged piece of hardware built to take some hits. Let it fail a little—filibuster, court, feds, whatever. Patch the holes with amendments if you want, or lean into the grind. Either way, stop fearing the crash. It’s how we debug the republic.
So, what’s your take? Ready to let the system rumble, or got a better way to secure the code? Hit me up—I’m all ears.

I really enjoy listening to non-technical people talk about technology when they get the bigger picture impacts and how it relates to our humanity.
I was reminded of this video by @k00b's post about an AI generated video of a victim forgiving his killer.
Piper says, "Computers are better at words than you. Than I". But they are machines. They cannot feel. They cannot have emotion.
This people honors me with their lips, but their heart is far from me
~ Matthew 15:8
Most of us hate it when people are fake with us. When they say things they don't mean. When they say things just to get something they want from us. Yet, we are quickly falling into this same trap with technology. Accepting it as real and human. I'm not suggesting we can't use technology but we have to be careful that we do not fall into this mechanical trap and forget what makes humans special.
We are emotional and spiritual beings. Though AI didn't exist during the times Jesus walked the earth read the verse above in a broader context.
Then Pharisees and scribes came to Jesus from Jerusalem and said, “Why do your disciples break the tradition of the elders? For they do not wash their hands when they eat.” He answered them, “And why do you break the commandment of God for the sake of your tradition? For God commanded, ‘Honor your father and your mother,’ and, ‘Whoever reviles father or mother must surely die.’ But you say, ‘If anyone tells his father or his mother, “What you would have gained from me is given to God,” he need not honor his father.’ So for the sake of your tradition you have made void the word of God. You hypocrites! Well did Isaiah prophesy of you, when he said:
“‘This people honors me with their lips,
but their heart is far from me;
in vain do they worship me,
teaching as doctrines the commandments of men.’”
Empty words. Words without meaning because they are not from a pure desire and love. You may not be a Christian but don't miss the significance of this. There is a value in being real. Sharing true emotion and heart. Don't fall into the trap of the culture of lies that surrounds us. I would rather hear true words with mistakes and less eloquence any day over something fake. I would rather share a real moment with the ones I love than a million fake moments. Embrace the messy imperfect but real world.

2025-05-06 19:49:39One of the best first rounds in recent memory just concluded. Let's recap our playoff contests.
Bracket Challenge
In our joint contest with Global Sports Central, @WeAreAllSatoshi is leading the way with 85 points, while me and some nostr jabroni are tied for second with 80 points.
The bad news is that they are slightly ahead of us, with an average score of 62 to our 60.8. We need to go back in time and make less stupid picks.
Points Challenge
With the Warriors victory, I jumped into a commanding lead over @grayruby. LA sure let most of you down. I say you hold @realBitcoinDog responsible for his beloved hometown's failures.
I still need @Car and @Coinsreporter to make their picks for this round. The only matchup they can choose from is Warriors (7) @ Timberwolves (6). Lucky for them, that's probably the best one to choose from.
| Stacker | Points | |---------|--------| | @Undisciplined | 25| | @grayruby | 24| | @Coinsreporter | 19 | | @BlokchainB | 19| | @Carresan | 18 | | @gnilma | 18 | | @WeAreAllSatoshi | 12 | | @fishious | 11 | | @Car | 1 |

2025-05-06 16:23:25"I tried pasting my login key into the text field, but no luck—it just wouldn't work. Turns out, the login field becomes completely unusable whenever the on-screen keyboard shows up on my phone. So either no one ever bothered to test this on a phone, or they did and thought, ‘Eh, who needs to actually log in anyway?’."
### \ \ Develop and evolve
Any technology or industry at the forefront of innovation faces the same struggle. Idealists, inventors, and early adopters jump in first, working to make things usable for the technical crowd. Only later do the products begin to take shape for the average user.
Bitcoin’s dropping the Ball on usability (and user-experience)
First, we have to acknowledge the progress we've made. Bitcoin has come a long way in terms of usability—no doubt about it. Even if I still think it’s bad, it’s nowhere near as terrible as it was ten or more years ago. The days of printing a paper wallet from some shady website and hoping it would still work months or years later are behind us. The days of buggy software never getting fixed are mostly over.
The Bitcoin technology itself made progress through many BIPs (Bitcoin Improvement Proposals) and combined with an increasing number of apps, devs, websites and related networks (Liquid, Lightning, Nostr, ....) we can say that we're seeing a strong ecosystem going its way. The ecosystem is alive and expanding, and technically, things are clearly working. The problem is that we’re still building with a mindset where developers and project managers consider usability—but don’t truly care about it in practice. They don’t lead with it. (Yes, there are always exceptions.)
All that progress looks cool, when you see the latest releases of hardware wallets, software wallets, exchanges, nostr clients and services built purely for bitcoin, you're usually thinking that we've progressed nicely. But I want to focus on the downside of all these shiny tools. Because if Bitcoin has made it this far, it’s mostly thanks to people who deeply understand its value and are stubborn enough to push through the friction. They don’t give up when the user experience sucks.
Many bitcoiners completely lost their perspective on the software front in my opinion. Because we could have been so much further ahead, and we didn't because some of the most important components on the user-facing side of Bitcoin (arguably the most important part) hasn’t kept pace with the popularity and possible growth. And that should be a great concern, because Bitcoin is meant to be open and accessible. The blockchain is public. This is supposed to be for everyone. This is an open ledger technology so in theory everything is user-facing to one extent or another. Yet we fail on that front to make the glue stick. Somewhere, we’re easily amused by the tools we create, and often contains hurdles we can’t see or feel. While users reject it after 5 seconds tops.
We didn’t came a lot further yet, because we’ve ignored usability at its core (pun intended).
I’m not talking about usability in the “it works on my machine” sense. I’m talking about usability that meets the standard of modern apps. Think Spotify, Instagram, Uber, Gmail. Products that ordinary people use without reading a manual or digging through forums.
That’s the bar. We’re still far from it.
Bad UX scares your grandma away
… and that’s how many bitcoiners apparently like it.
Subsequently, when I say usability, I’m using it as an umbrella term. For me, it covers user experience, user interface, and real-life, full-cycle testing—from onboarding a brand new user to rolling out a new version of the app. And oh boy, our onboarding is so horrible. (“Hey wanna try bitcoin? Here’s an app that takes up to 4 minutes or more to get though, but wait, you’ll have to install a plugin, or wait I’ll send you an on-chain transaction…)
Take a look at the listings on Bitvocation, an excellent job board for Bitcoiners and related projects. You’ll quickly notice a pattern: almost no companies are hiring software testers. It’s marketing, more marketing, some sales, and of course, full-stack developers. But … No testers.
Because testing has become something that’s often skipped or automated in a hurry. Maybe the devs run a test locally to confirm that the feature they just built doesn’t crash outright. That’s it. And if testing does happen at a company, it’s usually shallow—focused only on the top five percent of critical bugs. The finer points that shape real user experience, like button placement, navigation flow, and responsiveness, are dumped on “the community.”
Which leads to some software being rushed out to production, and only then do teams discover how many problems exist in the real world. If there’s anyone left to care that is, since most teams are scattered all over the world and get paid by the hour by some VC firm on a small runway to a launch date.
This has real life consequences I’ve seen for myself with new users. Like a lightning wallet having a +5 minute onboarding time, and a fat on-screen error for the new users, or a hardware wallet stuck in an endless upgrade loop, just because nobody tested it on a device that was “old” (as in, one year old).
The result is clear: usability and experience testing are so low on the priority list, they may as well not exist. And that’s tragic, because the enthusiasm of new users gets crushed the moment they run into what I call Linux’plaining.
That’s when something obvious fails — like a lookup command that’s copied straight from their own help documentation but doesn’t work — and the answer you get as a user is something like: “Yeah, but first you have to…” followed by an explanation that isn’t mentioned anywhere in the interface or documentation. You were just supposed to know. No one updates the documentation, and no one cares. As most of the projects are very temporary or don’t really care if it succeeds or not, because they’re bitcoiners and bitcoin always wins. Just like PGP always was super cool and good, and users should just be smarter.
Lessons from the past usability disasters
We can always learn from the past especially when its precedents are still echoing through the systems we use today
So here goes, some examples from the legacy / fiat industry:
Lotus Notes, for example. Once a titan in enterprise communication software, which managed to capture about 145 million mailboxes. But its downfall is an example of what happens when you ignore and keep ignoring real-life user needs and fail to evolve with the market. Software like that doesn’t just fade, it collapses under the weight of its own inertia and bloat. If you think bitcoin can’t have that, yes… we’re of course not having a competitor in the market (hard money is hard money, not a mailbox or office software provider of course). But we can erode trust to the extent that it becomes LotusNotes’d.
Its archaic 1990s interface came with clunky navigation and a chaotic document management system. Users got frustrated fast—basic tasks took too long. Picture this: you're stuck in a cubicle, trying to find the calendar function in Lotus Notes while a giant office printer hisses and spits out stacks of paper behind you. The platform never made the leap to modern expectations. It failed to deliver proper mobile clients and clung to outdated tech like LotusScript and the Domino architecture, which made it vulnerable to security issues and incompatible with the web standards of the time. By 2012, IBM pulled the plug on the Lotus brand, as businesses moved en masse to cloud-based alternatives.
Another kind of usability failure has plagued PGP1 (and still does so after 34 years). PGP (Pretty Good Privacy) is a time-tested and rock-solid method for encryption and key exchange, but it’s riddled with usability problems, especially for anyone who isn’t technically inclined.
Its very nature and complexity are already steep hurdles (and yes, you can’t make it fully easy without compromising how it’s supposed to work—granted). But the real problem? Almost zero effort has gone into giving even the most eager new users a manageable learning curve. That neglect slowly killed off any real user base—except for the hardcore encryption folks who already know what they’re doing.
Ask anyone in a shopping street or the historic center of your city if they’ve heard of PGP. And on the off chance someone knows it’s not a trendy new fast-food joint called “Perfectly Grilled Poultry,” the odds of them having actually used it in the past six months are basically zero, unless you happen to bump into that one neckbeard guy in his 60s wearing a stained Star Wars T-shirt named Leonard.
The builders of PGP made one major mistake: they never treated usability as a serious design goal (that’s normal for people knee deep in encryption, I get that, it’s the way it is). PGP is fantastic on itself. Other companies and projects tried to build around it, but while they stumbled, tools like Signal and ProtonMail stepped in; offering the same core features of encryption and secure messaging, minus the headache. They delivered what PGP never could: powerful functionality wrapped in something regular people can actually use. Now, we’ve got encrypted communication flowing through apps like Signal, where all the complex tech is buried so deep in the background, the average user doesn’t even realize it’s there. ProtonMail went one step further even, integrating PGP so cleanly that users never need to exchange keys or understand the cryptography behind it all, yet still benefit from bulletproof encryption.
There’s no debate—this shift is a good thing. History shows that unusable software fades into irrelevance. Whether due to lack of interest, failure to reach critical mass, or a competitor swooping in to eat market share, clunky tools don’t survive. Now, to be clear, Bitcoin doesn’t have to worry about that kind of threat. There’s no real competition when it comes to hard money. Unless, of course, you genuinely believe that flashy shitcoins are a viable alternative—in which case, you might as well stop reading here and go get yourself scammed on the latest Solana airdrop or whatever hype train’s leaving the station today for the degens.
The main takeaway here is that Bitcoin must avoid becoming the next Lotus Notes, bloated with features but neglected by users—or the next PGP, sidelined by its own lack of usability. That kind of trajectory would erode trust, especially if usability and onboarding keep falling behind. And honestly, we’re already seeing signs of this in bitcoin. User adoption in Europe, especially in countries like Germany is noticeably lagging. The introduction of the EU’s MiCA regulations isn’t helping either. Most of the companies that were actually pushing adoption are now either shutting down, leaving the EU, or jumping through creative loopholes just to stay alive. And the last thing on anyone’s mind is improving UX. It takes time, effort, and specialized people to seriously think through how to build this properly, from the beginning, with this ease of use and onboarding in mind. That’s a luxury most teams can’t or won’t prioritize right now. Understandably when the lack of funds is still a major issue within the bitcoin space. (for people sitting on hard money, there’s surprisingly little money flowing into useful projects that aren’t hyped up empty boxes)
The number of nodes being set up by end users worldwide isn’t exactly skyrocketing either. Sure, there’s some growth but let’s not overstate it. Based on Bitnodes’ snapshots taken in March of each year, we’re looking at: 2022 : around 10500 2023 : around 17000 2024 : around 18500 2025 : around 21000 (I know there are different methods of measuring these, like read-only nodes, the % change is roughly the same nonetheless)
In my opinion, if we had non-clunky software that was actually released with proper testing and usability in mind, we could’ve easily doubled those node numbers. A bad user experience with a wallet spreads fast—and brings in exactly zero new users. The same goes for people trying to set up a miner or spin up a node, only to give up after a few frustrating steps. Sure, there are good people out there making guides and videos2 to help mitigate those hurdles, and that helps. But let’s be honest: there’s still very little “wow” factor when average users interact with most Bitcoin software. Almost every time they walk away, it’s because of one of two things—usability issues or bugs.
For the record: if a user can’t set up a wallet because the interface is so rotten or poorly tested, so they don’t know where to click or how to even select a seed word from a list, then that’s a problem — that’s a bug. Argue all you want: sure, it’s not a code-level bug and no, it’s not a system crash. But it is a usability failure. Call it onboarding friction, UX flaw, whatever fits your spreadsheet or circus Maximus of failures in your ticketing system. Bottom line: if your software doesn’t help users accomplish its core purpose, it’s broken. It’s a bug. Pretending it’s something a copywriter or marketing team can fix is pure deflection. The solution isn’t to relabel the problem, 1990’s telecom-style, just to avoid dealing with it. It’s to actually sit down, think, collaborate, and go through the issue, and getting real solutions out. ”No it’s not an issue, that’s how it works” like someone from a failing (and by now defunct) wallet told me once, is not a solution.
You got 21 seconds
The user can’t be onboarded because your software has an “issue”? In my book, that’s a bug. The usual response when you report it? “Yeah, that’s not a priority.” Well, guess what? It actually is a priority. All these small annoyances, hurdles, and bits of BS still plague this industry, and they make the whole experience miserable for regular people trying it out for the first time. The first 21 seconds (yeah, you see what I did there) are the most important when someone opens new software. If it doesn’t click right away—if they’re fiddling with sats or dollar signs, or hunting for some hidden setting buried behind a tiny arrow—it’s game over. They’re annoyed. They’re gone.
And this is exactly why we’re seeing a flood of shitcoin apps sweeping new users off their feet with "faster apps" or "nicer designs" apps that somehow can afford the UI specialists and slick, centralized setups to spread their lies and scams.
I hate to say it, but the Phantom wallet for example, for the Solana network, loaded with fake airdrop schemes and the most blatant scams — has a far better UX than most Bitcoin wallets and Lightning Wallets. Learn from it. Download that **** and get to know what we do wrong and how we can learn from the enemy.
That’s a hard truth. So, instead of just screaming “Uh, shitcooooin!” (yes, we know it is), maybe we should start learning from it. Their apps are better than ours in terms of UI and UX. They attract more people 5x faster (we know that’s also because of the fast gains and retardation playing with the marketing) but we can’t keep ignoring that. Somehow these apps attract more than our trustworthiness, our steady, secure, decentralized hard money truth.
It’s like stepping into one of the best Italian restaurants in town—supposedly. But then the menu’s a mess, the staff is scrolling on their phones, and something smells burnt coming from the kitchen. So, what do you do? You walk out. You cross the street to the fast food joint and order a burger and fries. And as you’re walking out with your food, someone from the Italian place yells at you: “Fast food is bad!” ”Yeah man I know, I wanted a nice Spaghetti aglio e olio, but here I am, digesting a cheeseburger that felt rather spongy.” (the problem is so gone so deep now, that users just walk past that Italian restaurant, don’t even recognize it as a restaurant because it doesn’t have cheeseburgers).
Fear of the dark
Technical people, not marketeers built bitcoin, it’s build on hundreds of small building blocks that interacted over time to have the bitcoin network and it’s immer evolving value. At one point David Chaum cooked up eCash, using blind signatures to let people send digital money anonymously — except it was still stuck on clunky centralized servers. Go back even further, to the 1970s, when Diffie, Hellman, and Rivest introduced public-key cryptography—the magic sauce that gave us secure digital signatures and authentication, making sure your messages stayed private and tamper-proof.
Fast forward to the 1990s, where peer-to-peer started to take off, decentralized networks getting started. Adam Back’s Hashcash in ‘97 used proof-of-work to fight email spam, and the cypherpunks were all about sticking it to the man with privacy-first, the invention 199 Human-Readable 128-bit keys3, decentralized systems. We started to swap files over p2p networks and later, torrents.
All these parts—anonymous cash, encryption, and leaderless networks finally clicked into place when Satoshi Nakamoto poured them into a chain of blocks, built on an ingenious “time-stamping” system: the timechain, or blockchain if you prefer. And just like that, Bitcoin was born—a peer-to-peer money system that didn’t need middlemen and actually worked without any central servers.
So yes, it’s only natural that Bitcoin and the many tools, born from math, obscurity, and cryptography, isn’t exactly always a user-interface darling. That’s also it’s charm for me in any case, as the core is robust and valuable beyond belief. That’s why we love to so see more use, more adoption.
But that doesn’t mean we can’t squash critical “show-stopper” bugs before releasing bitcoin-related software. And it sure as hell doesn’t mean we should act like jerks when a user points out something’s broken, confusing, or just doesn’t meet expectations. We can’t be complacent either about our role as builders of the next generations, as the core is hard money, and it would be a fatal mistake for the world to see it being used only for some rockstars from Wall Street and their counterparts to store their debt laden fiat. We can free people, make them better, make them elevate themselves. And yet, the people we try to elevate, we often alienate. All because we don’t test our stuff well enough. We should be so good, we blow the banking apps away. (they’re blowing themselves out of the market luckily with fiat “features” and overly over the top use of “analytics” to measure your carbon footprint for example).
We should be so damn professional that someone using Bitcoin apps for a full year wouldn’t even notice any bugs, because there wouldn’t be much to get annoyed by.
So… we have to do better. I’ve seen it time and time again — on Lightning tipping apps, Nostr plugins, wallets, hardware wallets, even metal plates we can screw up somehow … you name it. “It works on my machine”, isn’t enough anymore! Those days are over.
Even apps built with solid funding and strong dev and test teams like fedi.xyz4 can miss the mark. While the idea was good and the app itself ran fine without too much hurdles and usual bugs. But usability failed on a different front: there was just nothing meaningful to do in the app beyond poking around, chatting a bit, and sending a few sats back and forth. The communities it’s supposed to connect, just aren’t there, or weren’t there “yet”.
It’s a beautifully designed application and a strong proof-of-concept for federated community funds. But then… nothing. No one I know uses it. Their last blogpost was from beginning of October 2024, which doesn’t bode well, writing this than 6 months after. That said, they got some great onboarding going, usually under 20 seconds, which proves it can be done right (even if it was all a front-end for a more complex backend).
As you can see “usability” is a broad terminology, covering technical aspects, user-interface, but also use-cases. Even if you have a cool app that works really well and is well thought-out users won’t use it if there’s no real substance. You can’t get that critical mass by waiting for customers to come in or communities to embrace it. They won’t, because most of the individuals already had past experiences with bitcoin apps or services, and there’s a reason for them not being on-board already.
A lot of bitcoin companies build tools for new people. Never for the lapsed people, the persons that came in, thought of it as an investment or “a coin”… then left because of a bad experience or the price going down in fiat. All the while we have some software that usually isn’t so kind to new people, or causes loss of funds and time. Even if they make one little “mistake” of not knowing the system beforehand.
Bitcoin’s Moby Dick
\ Bitcoin itself has a big issue here. The user base could grow faster, and more robust, if there wasn’t software that worked as a sort of repellent against users.
I especially see a younger and less tech-savvy audience absolutely disliking the software we have now. No matter if it’s Electrum’s desktop wallet (hardly the sexiest tool out there, although I like it myself, but it lacks some features), Sparrow, or any lightning wallet out there (safe for WoS). I even saw people disliking Proton wallet, which I personally thought of as something really slick, well-made and polished. But even that doesn’t cut it for many people, as the “account” and “wallet” system wasn’t clear enough for them. (You see, we all have the same bias, because we know bitcoin, we look at it from a perspective of “facepalm, of course it’s a wallet named “account”, but when you sit next to a new user, it becomes clear that this is a hurdle. (please proton wallet: name a wallet a wallet, not “account”. But most users already in bitcoin, love what you’re doing)
Naturally disliking usability
The same technically brilliant people who maintain Bitcoin and build its apps haven’t quite tapped into their inner Steve Jobs—if that person even exists in the Bitcoin space. Let’s be honest: the next iOS-style wow moment, or the kind of frictionless usability seen in Spotify or Instagram, probably won’t come from hardcore Bitcoin devs alone. In fact, some builders in the space seem to actively disregard—or even look down on—discussions about usability. Just mention names like Wallet of Satoshi (yes, we all know it’s a custodial frontend) or the need for smoother interactions with Bitcoin, and you’ll get eye-rolls or defensive rants instead of curiosity or openness.
Moving more towards a better user interface for things like Sparrow or Bitcoin Core for example, would bring all kinds of “bad things” according to some, and on top of that, bring in new users (noobs) that ask questions like: “Do you burn all these sats when I make a transaction?” (Yes, that’s a real one.)
I get the “usability sucks” gripe — fear of losing key features, dumbing things down, or opening the door to unwanted changes (like BIP proposals real bitcoiners hate) that tweak bitcoin to suit any user’s whim. Close to no one in bitcoin (really in bitcoin!) wants that, including me.
That fear is however largely unfounded; because Bitcoin doesn’t change without consensus. Any change that would undermine its core use or value proposition simply won’t make it through. And let’s be honest: most of the users who crave these “faster,” centralized alternatives—those drawn to slick apps, one-click solutions, and dopamine-driven UI—will either stick with fiat, ape into the shitcoin-of-the-month, or praise the shiny new CBDC once it drops (“much fast, much cool”). These degen types, chasing fiat gains and jackpot dreams, aren’t relevant to this story, No matter what we build for bitcoin, they’ll always love the fiat-story and will always dislike bitcoin because it’s not a jackpot for them. (Honestly, why don’t they just gamble at a casino?)
People who fear that improving usability will somehow bring down the Bitcoin network are being a bit too paranoid—and honestly, they often don’t understand what usability or proper testing actually means.
They treat it like fluff, when in reality it's fundamental. Usability doesn't mean dumbing things down or compromising Bitcoin's core values; it means understanding why your fancy new app isn’t being used by anyone outside of your bubble. Testing is the beating heart of getting things out with confidence. Nothing more satisfying in software building than to proudly show even your beta versions to users, knowing it’s well tested. It’s much more than clicking a few buttons and tossing your code on GitHub. It's about asking real questions: can someone outside your Telegram group actually use this and will it they be using the software at all?
If you create a Nostr app that opens an in-app browser window and then tries to log you in with your NIPS05 or NIPS07 or whatever number it is that authenticates you, then you need to think about how it’s going to work in real life. Have people already visited this underlying website? Is that website using the exact same mechanism? Is it really working like we think it is in the real world? (Some notable good things are happening with the development of Keychat for example, I have the feeling they get it, it’s not all bad). And yes, there are still bugs and things to improve there, they’re just starting. (The browser section and nostr login need some work imho).
Guess what? You can test your stuff. But it takes time and effort. The kind of effort that, if skipped, gets multiplied across thousands of people. Thousands of people wasting their time trying to use your app, hitting errors, assuming they did something wrong, retrying, googling workarounds—only to eventually realize: it’s not them. It’s a bug. A bug you didn’t catch. Because you didn’t test. And now everyone loses. And guess what? Those users? They’re not coming back.
A good example (to stay positive here) is Fountain App, where the first versions were , eh… let’s say not so good, and then quickly evolved into a company and product that works really well, and also listens to their users and fixes their bugs. The interface can still be better in my opinion, but it’s getting there. And it’s super good now.
A bad example? Alby. (Sorry to say.) It still suffers from a bloated, clunky interface and an onboarding flow that utterly confuses new or returning users. It just doesn’t get the job done. Opinions may vary, sure, but hand this app to any non-technical user and ask them to get online and do a Nostr zap. Watch what happens. If they even manage to get through the initial setup, that is.
Another example? Bitkit. When I tried transferring funds from the "savings" to the "spending" account, the wallet silently opened a Lightning channel—no warning, no explanation—and suddenly my coins were locked up. To make things worse, the wallet still showed the full balance as spendable, even though part of it was now stuck in that channel. That was in November 2024, the last time I touched Bitkit. I wasted too much time trying to figure it out, I haven’t looked back (assuming the project is even still alive, I didn’t see them pop up anywhere).
Some metal BIP39 backup tools are great in theory but poorly executed. I bought one that didn’t even include a simple instruction on how to open it. The person I gave it to spent two hours trying to open it with a screwdriver and even attempted drilling. Turns out, it just slides open with some pressure. A simple instruction would’ve saved all that frustration.
Builders often assume users “just get it,” but a small guide could’ve prevented all the hassle. It’s a small step, but it’s crucial for better user experience. So why not avoid such situations and put a friggin cheap piece of paper in the box so people know how to open it? (The creators would probably facepalm if they read this, “how can users nòt see this?”). Yeah,… put a paper in there with instructions.
That’s natural, because as a creator you’re “in” it, you know. You don’t see how others would overlook something so obvious.
Bitcoiners are extremely bad on that front.
I’ll dive deeper into some examples in part 2 of this post.

2025-05-06 16:11:35India csökkentené az atomerőművek építési idejét ambiciózus nukleáris céljai eléréséhez
India célja, hogy a jelenlegi 10 évről a „világszínvonalú” 6 évre csökkentse atomerőművi projektjeinek kivitelezési idejét, hogy elérje a 2047-re kitűzött, 100 GW beépített nukleáris kapacitást.
Az SBI Capital Markets (az Indiai Állami Bank befektetési banki leányvállalata) jelentése szerint ez segítene mérsékelni a korábbi költségtúllépéseket, és vonzóbbá tenné az országot a globális befektetők számára.
A jelentés szerint a jelenlegi, mintegy 8 GW kapacitás és a csak 7 GW-nyi építés alatt álló kapacitás mellett „jelentős gyorsítás” szükséges a célok eléréséhez.
A kormány elindította a „nukleáris energia missziót”, amelyhez körülbelül 2,3 milliárd dollárt (2 milliárd eurót) különített el K+F-re és legalább öt Bharat kis moduláris reaktor (BSMR) telepítésére, de további kihívásokat kell megoldania a célok eléréséhez.
Az építési idők csökkentése kulcsfontosságú, de a jelentés átfogó rendszerszintű reformokat is javasol, beleértve a gyorsabb engedélyezést, a földszerzési szabályok egyszerűsítését, az erőművek körüli védőtávolság csökkentését, és a szabályozó hatóság (Atomic Energy Regulatory Board) nagyobb önállóságát.
A jelentés szerint a nemzet korlátozott uránkészletei miatt elengedhetetlen az üzemanyagforrások diverzifikálása nemzetközi megállapodások révén, valamint az indiai nukleáris program 2. és 3. szakaszának felgyorsítása.
India háromlépcsős nukleáris programja célja egy zárt üzemanyagciklus kialakítása, amely a természetes uránra, a plutóniumra és végül a tóriumra épül. A 2. szakaszban gyorsneutronos reaktorokat használnak, amelyek több energiát nyernek ki az uránból, kevesebb bányászott uránt igényelnek, és a fel nem használt uránt új üzemanyaggá alakítják. A 3. szakaszban fejlett reaktorok működnek majd India hatalmas tóriumkészleteire alapozva.
2025 januárjában az indiai Nuclear Power Corporation (NPCIL) pályázatot írt ki Bharat SMR-ek telepítésére, először nyitva meg a nukleáris szektort indiai magáncégek előtt.
Eddig csak az állami tulajdonú NPCIL építhetett és üzemeltethetett kereskedelmi atomerőműveket Indiában.
A Bharat SMR-ek (a „Bharat” hindiül Indiát jelent) telepítése a „Viksit Bharat” („Fejlődő India”) program része.
Engedélyezési folyamat: „elhúzódó és egymásra épülő”
A Bharat atomerőmű fejlesztésének részletei továbbra sem világosak, de Nirmala Sitharaman pénzügyminiszter júliusban elmondta, hogy az állami National Thermal Power Corporation és a Bharat Heavy Electricals Limited közös vállalkozásában valósulna meg a fejlesztés.
Sitharaman hozzátette, hogy a kormány a magánszektorral közösen létrehozna egy Bharat Small Reactors nevű céget, amely SMR-ek és új nukleáris technológiák kutatás-fejlesztésével foglalkozna.
Az SBI jelentése szerint javítani kell az SMR programot, mert az engedélyezési folyamat jelenleg „elhúzódó és egymásra épülő”, és aránytalan kockázatot jelent a magánszereplők számára a reaktorfejlesztés során.
A program „stratégiailag jó helyzetben van a sikerhez”, mert szigorú belépési feltételeket támaszt, így csak komoly és alkalmas szereplők vehetnek részt benne.
A kormánynak azonban be kellene vezetnie egy kártérítési záradékot, amely védi a magáncégeket az üzemanyag- és nehézvíz-ellátás hiányától, amely az Atomenergia Minisztérium (DAE) hatáskörébe tartozik.
A jelentés szerint mind az üzemanyag, mind a nehézvíz ellátása a DAE-től függ, és „a hozzáférés hiánya” problémát jelenthet. India legtöbb kereskedelmi atomerőműve hazai fejlesztésű, nyomottvizes nehézvizes reaktor.
A jelentés szerint: „A meglévő szabályozási hiányosságok kezelése kulcsfontosságú, hogy a magánszektor vezethesse a kitűzött 100 GW nukleáris kapacitás 50%-ának fejlesztését 2047-ig.”
Az NPCIL nemrégiben közölte, hogy India 2031–32-ig további 18 reaktort kíván hozzáadni az energiamixhez, ezzel az ország nukleáris kapacitása 22,4 GW-ra nő.
A Nemzetközi Atomenergia-ügynökség adatai szerint Indiában 21 reaktor üzemel kereskedelmi forgalomban, amelyek 2023-ban az ország áramtermelésének körülbelül 3%-át adták. Hat egység van építés alatt.
Roszatom pert indított a leállított Hanhikivi-1 projekt miatt Finnországban
Az orosz állami Roszatom atomenergetikai vállalat pert indított Moszkvában a finn Fortum és Outokumpu cégek ellen, és 227,8 milliárd rubel (2,8 milliárd dollár, 2,4 milliárd euró) kártérítést követel a finnországi Hanhikivi-1 atomerőmű szerződésének felmondása miatt – derül ki bírósági dokumentumokból és a Roszatom közleményéből.
A Roszatom a „mérnöki, beszerzési és kivitelezési (EPC) szerződés jogellenes felmondása”, a részvényesi megállapodás, az üzemanyag-ellátási szerződés megsértése, valamint a kölcsön visszafizetésének megtagadása miatt követel kártérítést.
A Fortum a NucNetnek e-mailben azt írta, hogy „nem kapott hivatalos értesítést orosz perről”.
A Fortum 2025. április 29-i negyedéves jelentésében közölte, hogy a Roszatom finn leányvállalata, a Raos Project, valamint a Roszatom nemzetközi divíziója, a JSC Rusatom Energy International, illetve a Fennovoima (a Hanhikivi projektért felelős finn konzorcium) között a Hanhikivi EPC szerződésével kapcsolatban nemzetközi választottbírósági eljárás zajlik.
2025 februárjában a választottbíróság úgy döntött, hogy nincs joghatósága a Fortummal szembeni követelések ügyében. „Ez a döntés végleges volt, így a Fortum nem része a választottbírósági eljárásnak” – közölte a cég.
A Fortum 2015-ben kisebbségi tulajdonos lett a Fennovoima projektben, de a teljes tulajdonrészt 2020-ban leírta.
A Fennovoima konzorcium, amelyben a Roszatom a Raos-on keresztül 34%-os kisebbségi részesedéssel rendelkezett, 2022 májusában felmondta a Hanhikivi-1 létesítésére vonatkozó szerződést az ukrajnai háború miatti késedelmek és megnövekedett kockázatok miatt.
A projekt technológiája az orosz AES-2006 típusú nyomottvizes reaktor lett volna.
2021 áprilisában a Fennovoima közölte, hogy a projekt teljes beruházási költsége 6,5–7 milliárd euróról 7–7,5 milliárd euróra nőtt.
2022 augusztusában a Roszatom és a Fennovoima kölcsönösen milliárdos kártérítési igényt nyújtott be egymás ellen a projekt leállítása miatt.
A Fennovoima nemzetközi választottbírósági eljárást indított 1,7 milliárd euró előleg visszafizetéséért. A Roszatom 3 milliárd eurós ellenkeresetet nyújtott be. Ezek az ügyek jelenleg is nemzetközi bíróságok előtt vannak.
Dél-koreai delegáció Csehországba utazik nukleáris szerződés aláírására
Egy dél-koreai delegáció 2025. május 6-án Csehországba utazik, hogy részt vegyen egy több milliárd dolláros szerződés aláírásán, amely két új atomerőmű építéséről szól a Dukovany telephelyen – közölte a dél-koreai kereskedelmi, ipari és energetikai minisztérium.
A delegáció, amelyben kormányzati és parlamenti tisztviselők is vannak, kétnapos prágai látogatásra indul, hogy részt vegyen a szerdára tervezett aláírási ceremónián.
A küldöttség találkozik Petr Fiala cseh miniszterelnökkel és Milos Vystrcil szenátusi elnökkel is, hogy megvitassák a Dukovany projektet.
Fiala múlt héten bejelentette, hogy Prága május 7-én írja alá a Dukovany szerződést a Korea Hydro & Nuclear Power (KHNP) céggel.
A cseh versenyhivatal nemrég engedélyezte a szerződés aláírását a KHNP-vel, miután elutasította a francia EDF fellebbezését.
A versenyhivatal április 24-i döntése megerősítette a korábbi ítéletet, amelyet az EDF megtámadott, miután 2024 júliusában elvesztette a tenderpályázatot a KHNP-vel szemben.
Ez lehetővé teszi, hogy a két dél-koreai APR1400 reaktor egység szerződését aláírják Dukovanyban, Dél-Csehországban. A szerződés az ország történetének legnagyobb energetikai beruházása, értéke legalább 400 milliárd korona (16 milliárd euró, 18 milliárd dollár).
A szerződést eredetileg márciusban írták volna alá, de a vesztes pályázók (EDF, Westinghouse) fellebbezései, dél-koreai politikai bizonytalanságok és a cseh cégek lokalizációs igényei miatt csúszott.
A KHNP januárban rendezte a szellemi tulajdonjogi vitát a Westinghouse-zal, amely korábban azt állította, hogy a KHNP az ő technológiáját használja az APR1400 reaktorokban.
A szerződés aláírása Dél-Korea első külföldi atomerőmű-építési projektje lesz 2009 óta, amikor a KHNP négy APR1400 reaktort épített az Egyesült Arab Emírségekben, Barakahban.
Csehországban hat kereskedelmi reaktor működik: négy orosz VVER-440-es Dukovanyban, két nagyobb VVER-1000-es Temelínben. Az IAEA szerint ezek az egységek a cseh áramtermelés mintegy 36,7%-át adják.
Az USA-nak „minél előbb” új reaktort kell építenie – mondta a DOE jelöltje a szenátusi bizottság előtt
Az USA-nak minél előbb új atomerőművet kell építenie, és elő kell mozdítania a fejlett reaktorok fejlesztését, engedélyezését és telepítését – hangzott el a szenátusi energiaügyi bizottság előtt.
Ted Garrish, aki a DOE nukleáris energiaügyi helyettes államtitkári posztjára jelöltként jelent meg, elmondta: az országnak új reaktort kell telepítenie, legyen az nagy, kis moduláris vagy mikroreaktor.
Az USA-ban jelenleg nincs épülő kereskedelmi atomerőmű, az utolsó kettő, a Vogtle-3 és Vogtle-4 2023-ban, illetve 2024-ben indult el Georgiában.
„A nukleáris energia kivételes lehetőség a növekvő villamosenergia-igény megbízható, megfizethető és biztonságos kielégítésére” – mondta Garrish, aki tapasztalt atomenergetikai vezető. Szerinte az USA-nak nemzetbiztonsági okokból is fejlesztenie kell a hazai urándúsító ipart.
Vizsgálni kell a nemzetközi piacot és a kormányközi megállapodások lehetőségét az amerikai nukleáris fejlesztők és ellátási láncok számára, valamint meg kell oldani a kiégett fűtőelemek elhelyezésének problémáját.
1987-ben a Kongresszus a nevadai Yucca Mountain-t jelölte ki a kiégett fűtőelemek végleges tárolóhelyének, de 2009-ben az Obama-adminisztráció leállította a projektet.
Az USA-ban az 1950-es évek óta mintegy 83 000 tonna radioaktív hulladék, köztük kiégett fűtőelem halmozódott fel, amelyet jelenleg acél- és betonkonténerekben tárolnak az erőművek telephelyein.
Garrish korábban a DOE nemzetközi ügyekért felelős helyettes államtitkára volt (2018–2021), jelenleg az Egyesült Haladó Atomenergia Szövetség igazgatótanácsának elnöke.
Egyéb hírek
Szlovénia közös munkát sürget az USA-val a nukleáris energiában:
Az USA és Horvátország tisztviselői együttműködésről tárgyaltak Közép- és Délkelet-Európa energiaellátásának diverzifikálása érdekében, különös tekintettel a kis moduláris reaktorokra (SMR). Horvátország és Szlovénia közösen tulajdonolja a szlovéniai Krško atomerőművet, amely egyetlen 696 MW-os nyomottvizes reaktorával Horvátország áramfogyasztásának 16%-át, Szlovéniáénak 20%-át adja. Szlovénia fontolgatja egy második blokk építését, de tavaly elhalasztotta az erről szóló népszavazást.Malawi engedélyezi a Kayelekera uránbánya újraindítását:
A Malawi Atomenergia Hatóság kiadta a sugárbiztonsági engedélyt a Lotus (Africa) Limited számára, így újraindulhat a Kayelekera uránbánya, amely több mint egy évtizede, 2014 óta állt a zuhanó uránárak és biztonsági problémák miatt. A bánya 85%-át az ausztrál Lotus Resources helyi leányvállalata birtokolja. A Lotus szerint a bánya újraindítása teljesen finanszírozott, kb. 43 millió dollár (37 millió euró) tőkével.Venezuela és Irán nukleáris együttműködést tervez:
Venezuela és Irán a nukleáris tudomány és technológia terén való együttműködésről tárgyalt. Az iráni állami média szerint Mohammad Eslami, az Iráni Atomenergia Szervezet vezetője és Alberto Quintero, Venezuela tudományos miniszterhelyettese egyetemi és kutatási programok elindításáról egyeztetett. Venezuelában nincs kereskedelmi atomerőmű, de 2010-ben Oroszországgal írt alá megállapodást új atomerőművek lehetőségéről. Iránnak egy működő atomerőműve van Bushehr-1-nél, egy másik ugyanott épül, mindkettőt Oroszország szállította. -

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 .

2025-03-25 17:43:44One 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.

2025-05-06 14:24:22Introduction
Bitcoin’s
OP_RETURN
opcode, a mechanism for embedding small data in transactions, has ignited a significant debate within the Bitcoin community. Originally designed to support limited metadata while preserving Bitcoin’s role as a peer-to-peer electronic cash system,OP_RETURN
is now at the center of proposals that could redefine Bitcoin’s identity. The immutable nature of Bitcoin’s timechain makes it an attractive platform for data storage, creating tension with those who prioritize its monetary function. This discussion, particularly around Bitcoin Core pull request #32406 (GitHub PR #32406), highlights a critical juncture for Bitcoin’s future.What is
OP_RETURN
?Introduced in 2014,
OP_RETURN
allows users to attach up to 80 bytes of data to a Bitcoin transaction. Unlike other transaction outputs,OP_RETURN
outputs are provably unspendable, meaning they don’t burden the Unspent Transaction Output (UTXO) set—a critical database for Bitcoin nodes. This feature was a compromise to provide a standardized, less harmful way to include metadata, addressing earlier practices that embedded data in ways that bloated the UTXO set. The 80-byte limit and restriction to oneOP_RETURN
output per transaction are part of Bitcoin Core’s standardness rules, which guide transaction relay and mining but are not enforced by the network’s consensus rules (Bitcoin Stack Exchange).Standardness vs. Consensus Rules
Standardness rules are Bitcoin Core’s default policies for relaying and mining transactions. They differ from consensus rules, which define what transactions are valid across the entire network. For
OP_RETURN
: - Consensus Rules: AllowOP_RETURN
outputs with data up to the maximum script size (approximately 10,000 bytes) and multiple outputs per transaction (Bitcoin Stack Exchange). - Standardness Rules: LimitOP_RETURN
data to 80 bytes and one output per transaction to discourage excessive data storage and maintain network efficiency.Node operators can adjust these policies using settings like
-datacarrier
(enables/disablesOP_RETURN
relay) and-datacarriersize
(sets the maximum data size, defaulting to 83 bytes to account for theOP_RETURN
opcode and pushdata byte). These settings allow flexibility but reflect Bitcoin Core’s default stance on limiting data usage.The Proposal: Pull Request #32406
Bitcoin Core pull request #32406, proposed by developer instagibbs, seeks to relax these standardness restrictions (GitHub PR #32406). Key changes include: - Removing Default Size Limits: The default
-datacarriersize
would be uncapped, allowing largerOP_RETURN
data without a predefined limit. - Allowing Multiple Outputs: The restriction to oneOP_RETURN
output per transaction would be lifted, with the total data size across all outputs subject to a configurable limit. - Deprecating Configuration Options: The-datacarrier
and-datacarriersize
settings are marked as deprecated, signaling potential removal in future releases, which could limit node operators’ ability to enforce custom restrictions.This proposal does not alter consensus rules, meaning miners and nodes can already accept transactions with larger or multiple
OP_RETURN
outputs. Instead, it changes Bitcoin Core’s default relay policy to align with existing practices, such as miners accepting non-standard transactions via services like Marathon Digital’s Slipstream (CoinDesk).Node Operator Flexibility
Currently, node operators can customize
OP_RETURN
handling: - Default Settings: Relay transactions with oneOP_RETURN
output up to 80 bytes. - Custom Settings: Operators can disableOP_RETURN
relay (-datacarrier=0
) or adjust the size limit (e.g.,-datacarriersize=100
). These options remain in #32406 but are deprecated, suggesting that future Bitcoin Core versions might not support such customization, potentially standardizing the uncapped policy.Arguments in Favor of Relaxing Limits
Supporters of pull request #32406 and similar proposals argue that the current restrictions are outdated and ineffective. Their key points include: - Ineffective Limits: Developers bypass the 80-byte limit using methods like Inscriptions, which store data in other transaction parts, often at higher cost and inefficiency (BitcoinDev Mailing List). Relaxing
OP_RETURN
could channel data into a more efficient format. - Preventing UTXO Bloat: By encouragingOP_RETURN
use, which doesn’t affect the UTXO set, the proposal could reduce reliance on harmful alternatives like unspendable Taproot outputs used by projects like Citrea’s Clementine bridge. - Supporting Innovation: Projects like Citrea require more data (e.g., 144 bytes) for security proofs, and relaxed limits could enable new Layer 2 solutions (CryptoSlate). - Code Simplification: Developers like Peter Todd argue that these limits complicate Bitcoin Core’s codebase unnecessarily (CoinGeek). - Aligning with Practice: Miners already process non-standard transactions, and uncapping defaults could improve fee estimation and reduce reliance on out-of-band services, as noted by ismaelsadeeq in the pull request discussion.In the GitHub discussion, developers like Sjors and TheCharlatan expressed support (Concept ACK), citing these efficiency and innovation benefits.
Arguments Against Relaxing Limits
Opponents, including prominent developers and community members, raise significant concerns about the implications of these changes: - Deviation from Bitcoin’s Purpose: Critics like Luke Dashjr, who called the proposal “utter insanity,” argue that Bitcoin’s base layer should prioritize peer-to-peer cash, not data storage (CoinDesk). Jason Hughes warned it could turn Bitcoin into a “worthless altcoin” (BeInCrypto). - Blockchain Bloat: Additional data increases the storage and processing burden on full nodes, potentially making node operation cost-prohibitive and threatening decentralization (CryptoSlate). - Network Congestion: Unrestricted data could lead to “spam” transactions, raising fees and hindering Bitcoin’s use for financial transactions. - Risk of Illicit Content: The timechain’s immutability means data, including potentially illegal or objectionable content, is permanently stored on every node. The 80-byte limit acts as a practical barrier, and relaxing it could exacerbate this issue. - Preserving Consensus: Developers like John Carvalho view the limits as a hard-won community agreement, not to be changed lightly.
In the pull request discussion, nsvrn and moth-oss expressed concerns about spam and centralization, advocating for gradual changes. Concept NACKs from developers like wizkid057 and Luke Dashjr reflect strong opposition.
Community Feedback
The GitHub discussion for pull request #32406 shows a divided community: - Support (Concept ACK): Sjors, polespinasa, ismaelsadeeq, miketwenty1, TheCharlatan, Psifour. - Opposition (Concept NACK): wizkid057, BitcoinMechanic, Retropex, nsvrn, moth-oss, Luke Dashjr. - Other: Peter Todd provided a stale ACK, indicating partial or outdated support.
Additional discussions on the BitcoinDev mailing list and related pull requests (e.g., #32359 by Peter Todd) highlight similar arguments, with #32359 proposing a more aggressive removal of all
OP_RETURN
limits and configuration options (GitHub PR #32359).| Feedback Type | Developers | Key Points | |---------------|------------|------------| | Concept ACK | Sjors, ismaelsadeeq, others | Improves efficiency, supports innovation, aligns with mining practices. | | Concept NACK | Luke Dashjr, wizkid057, others | Risks bloat, spam, centralization, and deviation from Bitcoin’s purpose. | | Stale ACK | Peter Todd | Acknowledges proposal but with reservations or outdated support. |
Workarounds and Their Implications
The existence of workarounds, such as Inscriptions, which exploit SegWit discounts to embed data, is a key argument for relaxing
OP_RETURN
limits. These methods are costlier and less efficient, often costing more thanOP_RETURN
for data under 143 bytes (BitcoinDev Mailing List). Supporters argue that formalizing largerOP_RETURN
data could streamline these use cases. Critics, however, see workarounds as a reason to strengthen, not weaken, restrictions, emphasizing the need to address underlying incentives rather than accommodating bypasses.Ecosystem Pressures
External factors influence the debate: - Miners: Services like Marathon Digital’s Slipstream process non-standard transactions for a fee, showing that market incentives already bypass standardness rules. - Layer 2 Projects: Citrea’s Clementine bridge, requiring more data for security proofs, exemplifies the demand for relaxed limits to support innovative applications. - Community Dynamics: The debate echoes past controversies, like the Ordinals debate, where data storage via inscriptions raised similar concerns about Bitcoin’s purpose (CoinDesk).
Bitcoin’s Identity at Stake
The
OP_RETURN
debate is not merely technical but philosophical, questioning whether Bitcoin should remain a focused monetary system or evolve into a broader data platform. Supporters see relaxed limits as a pragmatic step toward efficiency and innovation, while opponents view them as a risk to Bitcoin’s decentralization, accessibility, and core mission. The community’s decision will have lasting implications, affecting node operators, miners, developers, and users.Conclusion
As Bitcoin navigates this crossroads, the community must balance the potential benefits of relaxed
OP_RETURN
limits—such as improved efficiency and support for new applications—against the risks of blockchain bloat, network congestion, and deviation from its monetary roots. The ongoing discussion, accessible via pull request #32406 on GitHub (GitHub PR #32406). Readers are encouraged to explore the debate and contribute to ensuring that any changes align with Bitcoin’s long-term goals as a decentralized, secure, and reliable system. -

2025-03-18 20:47:50Warning: This piece contains a conversation about difficult topics. Please proceed with caution.
TL;DR please educate your children about online safety.
Julian Assange wrote in his 2012 book Cypherpunks, “This book is not a manifesto. There isn’t time for that. This book is a warning.” I read it a few times over the past summer. Those opening lines definitely stood out to me. I wish we had listened back then. He saw something about the internet that few had the ability to see. There are some individuals who are so close to a topic that when they speak, it’s difficult for others who aren’t steeped in it to visualize what they’re talking about. I didn’t read the book until more recently. If I had read it when it came out, it probably would have sounded like an unknown foreign language to me. Today it makes more sense.
This isn’t a manifesto. This isn’t a book. There is no time for that. It’s a warning and a possible solution from a desperate and determined survivor advocate who has been pulling and unraveling a thread for a few years. At times, I feel too close to this topic to make any sense trying to convey my pathway to my conclusions or thoughts to the general public. My hope is that if nothing else, I can convey my sense of urgency while writing this. This piece is a watchman’s warning.
When a child steps online, they are walking into a new world. A new reality. When you hand a child the internet, you are handing them possibilities—good, bad, and ugly. This is a conversation about lowering the potential of negative outcomes of stepping into that new world and how I came to these conclusions. I constantly compare the internet to the road. You wouldn’t let a young child run out into the road with no guidance or safety precautions. When you hand a child the internet without any type of guidance or safety measures, you are allowing them to play in rush hour, oncoming traffic. “Look left, look right for cars before crossing.” We almost all have been taught that as children. What are we taught as humans about safety before stepping into a completely different reality like the internet? Very little.
I could never really figure out why many folks in tech, privacy rights activists, and hackers seemed so cold to me while talking about online child sexual exploitation. I always figured that as a survivor advocate for those affected by these crimes, that specific, skilled group of individuals would be very welcoming and easy to talk to about such serious topics. I actually had one hacker laugh in my face when I brought it up while I was looking for answers. I thought maybe this individual thought I was accusing them of something I wasn’t, so I felt bad for asking. I was constantly extremely disappointed and would ask myself, “Why don’t they care? What could I say to make them care more? What could I say to make them understand the crisis and the level of suffering that happens as a result of the problem?”
I have been serving minor survivors of online child sexual exploitation for years. My first case serving a survivor of this specific crime was in 2018—a 13-year-old girl sexually exploited by a serial predator on Snapchat. That was my first glimpse into this side of the internet. I won a national award for serving the minor survivors of Twitter in 2023, but I had been working on that specific project for a few years. I was nominated by a lawyer representing two survivors in a legal battle against the platform. I’ve never really spoken about this before, but at the time it was a choice for me between fighting Snapchat or Twitter. I chose Twitter—or rather, Twitter chose me. I heard about the story of John Doe #1 and John Doe #2, and I was so unbelievably broken over it that I went to war for multiple years. I was and still am royally pissed about that case. As far as I was concerned, the John Doe #1 case proved that whatever was going on with corporate tech social media was so out of control that I didn’t have time to wait, so I got to work. It was reading the messages that John Doe #1 sent to Twitter begging them to remove his sexual exploitation that broke me. He was a child begging adults to do something. A passion for justice and protecting kids makes you do wild things. I was desperate to find answers about what happened and searched for solutions. In the end, the platform Twitter was purchased. During the acquisition, I just asked Mr. Musk nicely to prioritize the issue of detection and removal of child sexual exploitation without violating digital privacy rights or eroding end-to-end encryption. Elon thanked me multiple times during the acquisition, made some changes, and I was thanked by others on the survivors’ side as well.
I still feel that even with the progress made, I really just scratched the surface with Twitter, now X. I left that passion project when I did for a few reasons. I wanted to give new leadership time to tackle the issue. Elon Musk made big promises that I knew would take a while to fulfill, but mostly I had been watching global legislation transpire around the issue, and frankly, the governments are willing to go much further with X and the rest of corporate tech than I ever would. My work begging Twitter to make changes with easier reporting of content, detection, and removal of child sexual exploitation material—without violating privacy rights or eroding end-to-end encryption—and advocating for the minor survivors of the platform went as far as my principles would have allowed. I’m grateful for that experience. I was still left with a nagging question: “How did things get so bad with Twitter where the John Doe #1 and John Doe #2 case was able to happen in the first place?” I decided to keep looking for answers. I decided to keep pulling the thread.
I never worked for Twitter. This is often confusing for folks. I will say that despite being disappointed in the platform’s leadership at times, I loved Twitter. I saw and still see its value. I definitely love the survivors of the platform, but I also loved the platform. I was a champion of the platform’s ability to give folks from virtually around the globe an opportunity to speak and be heard.
I want to be clear that John Doe #1 really is my why. He is the inspiration. I am writing this because of him. He represents so many globally, and I’m still inspired by his bravery. One child’s voice begging adults to do something—I’m an adult, I heard him. I’d go to war a thousand more lifetimes for that young man, and I don’t even know his name. Fighting has been personally dark at times; I’m not even going to try to sugarcoat it, but it has been worth it.
The data surrounding the very real crime of online child sexual exploitation is available to the public online at any time for anyone to see. I’d encourage you to go look at the data for yourself. I believe in encouraging folks to check multiple sources so that you understand the full picture. If you are uncomfortable just searching around the internet for information about this topic, use the terms “CSAM,” “CSEM,” “SG-CSEM,” or “AI Generated CSAM.” The numbers don’t lie—it’s a nightmare that’s out of control. It’s a big business. The demand is high, and unfortunately, business is booming. Organizations collect the data, tech companies often post their data, governments report frequently, and the corporate press has covered a decent portion of the conversation, so I’m sure you can find a source that you trust.
Technology is changing rapidly, which is great for innovation as a whole but horrible for the crime of online child sexual exploitation. Those wishing to exploit the vulnerable seem to be adapting to each technological change with ease. The governments are so far behind with tackling these issues that as I’m typing this, it’s borderline irrelevant to even include them while speaking about the crime or potential solutions. Technology is changing too rapidly, and their old, broken systems can’t even dare to keep up. Think of it like the governments’ “War on Drugs.” Drugs won. In this case as well, the governments are not winning. The governments are talking about maybe having a meeting on potentially maybe having legislation around the crimes. The time to have that meeting would have been many years ago. I’m not advocating for governments to legislate our way out of this. I’m on the side of educating and innovating our way out of this.
I have been clear while advocating for the minor survivors of corporate tech platforms that I would not advocate for any solution to the crime that would violate digital privacy rights or erode end-to-end encryption. That has been a personal moral position that I was unwilling to budge on. This is an extremely unpopular and borderline nonexistent position in the anti-human trafficking movement and online child protection space. I’m often fearful that I’m wrong about this. I have always thought that a better pathway forward would have been to incentivize innovation for detection and removal of content. I had no previous exposure to privacy rights activists or Cypherpunks—actually, I came to that conclusion by listening to the voices of MENA region political dissidents and human rights activists. After developing relationships with human rights activists from around the globe, I realized how important privacy rights and encryption are for those who need it most globally. I was simply unwilling to give more power, control, and opportunities for mass surveillance to big abusers like governments wishing to enslave entire nations and untrustworthy corporate tech companies to potentially end some portion of abuses online. On top of all of it, it has been clear to me for years that all potential solutions outside of violating digital privacy rights to detect and remove child sexual exploitation online have not yet been explored aggressively. I’ve been disappointed that there hasn’t been more of a conversation around preventing the crime from happening in the first place.
What has been tried is mass surveillance. In China, they are currently under mass surveillance both online and offline, and their behaviors are attached to a social credit score. Unfortunately, even on state-run and controlled social media platforms, they still have child sexual exploitation and abuse imagery pop up along with other crimes and human rights violations. They also have a thriving black market online due to the oppression from the state. In other words, even an entire loss of freedom and privacy cannot end the sexual exploitation of children online. It’s been tried. There is no reason to repeat this method.
It took me an embarrassingly long time to figure out why I always felt a slight coldness from those in tech and privacy-minded individuals about the topic of child sexual exploitation online. I didn’t have any clue about the “Four Horsemen of the Infocalypse.” This is a term coined by Timothy C. May in 1988. I would have been a child myself when he first said it. I actually laughed at myself when I heard the phrase for the first time. I finally got it. The Cypherpunks weren’t wrong about that topic. They were so spot on that it is borderline uncomfortable. I was mad at first that they knew that early during the birth of the internet that this issue would arise and didn’t address it. Then I got over it because I realized that it wasn’t their job. Their job was—is—to write code. Their job wasn’t to be involved and loving parents or survivor advocates. Their job wasn’t to educate children on internet safety or raise awareness; their job was to write code.
They knew that child sexual abuse material would be shared on the internet. They said what would happen—not in a gleeful way, but a prediction. Then it happened.
I equate it now to a concrete company laying down a road. As you’re pouring the concrete, you can say to yourself, “A terrorist might travel down this road to go kill many, and on the flip side, a beautiful child can be born in an ambulance on this road.” Who or what travels down the road is not their responsibility—they are just supposed to lay the concrete. I’d never go to a concrete pourer and ask them to solve terrorism that travels down roads. Under the current system, law enforcement should stop terrorists before they even make it to the road. The solution to this specific problem is not to treat everyone on the road like a terrorist or to not build the road.
So I understand the perceived coldness from those in tech. Not only was it not their job, but bringing up the topic was seen as the equivalent of asking a free person if they wanted to discuss one of the four topics—child abusers, terrorists, drug dealers, intellectual property pirates, etc.—that would usher in digital authoritarianism for all who are online globally.
Privacy rights advocates and groups have put up a good fight. They stood by their principles. Unfortunately, when it comes to corporate tech, I believe that the issue of privacy is almost a complete lost cause at this point. It’s still worth pushing back, but ultimately, it is a losing battle—a ticking time bomb.
I do think that corporate tech providers could have slowed down the inevitable loss of privacy at the hands of the state by prioritizing the detection and removal of CSAM when they all started online. I believe it would have bought some time, fewer would have been traumatized by that specific crime, and I do believe that it could have slowed down the demand for content. If I think too much about that, I’ll go insane, so I try to push the “if maybes” aside, but never knowing if it could have been handled differently will forever haunt me. At night when it’s quiet, I wonder what I would have done differently if given the opportunity. I’ll probably never know how much corporate tech knew and ignored in the hopes that it would go away while the problem continued to get worse. They had different priorities. The most voiceless and vulnerable exploited on corporate tech never had much of a voice, so corporate tech providers didn’t receive very much pushback.
Now I’m about to say something really wild, and you can call me whatever you want to call me, but I’m going to say what I believe to be true. I believe that the governments are either so incompetent that they allowed the proliferation of CSAM online, or they knowingly allowed the problem to fester long enough to have an excuse to violate privacy rights and erode end-to-end encryption. The US government could have seized the corporate tech providers over CSAM, but I believe that they were so useful as a propaganda arm for the regimes that they allowed them to continue virtually unscathed.
That season is done now, and the governments are making the issue a priority. It will come at a high cost. Privacy on corporate tech providers is virtually done as I’m typing this. It feels like a death rattle. I’m not particularly sure that we had much digital privacy to begin with, but the illusion of a veil of privacy feels gone.
To make matters slightly more complex, it would be hard to convince me that once AI really gets going, digital privacy will exist at all.
I believe that there should be a conversation shift to preserving freedoms and human rights in a post-privacy society.
I don’t want to get locked up because AI predicted a nasty post online from me about the government. I’m not a doomer about AI—I’m just going to roll with it personally. I’m looking forward to the positive changes that will be brought forth by AI. I see it as inevitable. A bit of privacy was helpful while it lasted. Please keep fighting to preserve what is left of privacy either way because I could be wrong about all of this.
On the topic of AI, the addition of AI to the horrific crime of child sexual abuse material and child sexual exploitation in multiple ways so far has been devastating. It’s currently out of control. The genie is out of the bottle. I am hopeful that innovation will get us humans out of this, but I’m not sure how or how long it will take. We must be extremely cautious around AI legislation. It should not be illegal to innovate even if some bad comes with the good. I don’t trust that the governments are equipped to decide the best pathway forward for AI. Source: the entire history of the government.
I have been personally negatively impacted by AI-generated content. Every few days, I get another alert that I’m featured again in what’s called “deep fake pornography” without my consent. I’m not happy about it, but what pains me the most is the thought that for a period of time down the road, many globally will experience what myself and others are experiencing now by being digitally sexually abused in this way. If you have ever had your picture taken and posted online, you are also at risk of being exploited in this way. Your child’s image can be used as well, unfortunately, and this is just the beginning of this particular nightmare. It will move to more realistic interpretations of sexual behaviors as technology improves. I have no brave words of wisdom about how to deal with that emotionally. I do have hope that innovation will save the day around this specific issue. I’m nervous that everyone online will have to ID verify due to this issue. I see that as one possible outcome that could help to prevent one problem but inadvertently cause more problems, especially for those living under authoritarian regimes or anyone who needs to remain anonymous online. A zero-knowledge proof (ZKP) would probably be the best solution to these issues. There are some survivors of violence and/or sexual trauma who need to remain anonymous online for various reasons. There are survivor stories available online of those who have been abused in this way. I’d encourage you seek out and listen to their stories.
There have been periods of time recently where I hesitate to say anything at all because more than likely AI will cover most of my concerns about education, awareness, prevention, detection, and removal of child sexual exploitation online, etc.
Unfortunately, some of the most pressing issues we’ve seen online over the last few years come in the form of “sextortion.” Self-generated child sexual exploitation (SG-CSEM) numbers are continuing to be terrifying. I’d strongly encourage that you look into sextortion data. AI + sextortion is also a huge concern. The perpetrators are using the non-sexually explicit images of children and putting their likeness on AI-generated child sexual exploitation content and extorting money, more imagery, or both from minors online. It’s like a million nightmares wrapped into one. The wild part is that these issues will only get more pervasive because technology is harnessed to perpetuate horror at a scale unimaginable to a human mind.
Even if you banned phones and the internet or tried to prevent children from accessing the internet, it wouldn’t solve it. Child sexual exploitation will still be with us until as a society we start to prevent the crime before it happens. That is the only human way out right now.
There is no reset button on the internet, but if I could go back, I’d tell survivor advocates to heed the warnings of the early internet builders and to start education and awareness campaigns designed to prevent as much online child sexual exploitation as possible. The internet and technology moved quickly, and I don’t believe that society ever really caught up. We live in a world where a child can be groomed by a predator in their own home while sitting on a couch next to their parents watching TV. We weren’t ready as a species to tackle the fast-paced algorithms and dangers online. It happened too quickly for parents to catch up. How can you parent for the ever-changing digital world unless you are constantly aware of the dangers?
I don’t think that the internet is inherently bad. I believe that it can be a powerful tool for freedom and resistance. I’ve spoken a lot about the bad online, but there is beauty as well. We often discuss how victims and survivors are abused online; we rarely discuss the fact that countless survivors around the globe have been able to share their experiences, strength, hope, as well as provide resources to the vulnerable. I do question if giving any government or tech company access to censorship, surveillance, etc., online in the name of serving survivors might not actually impact a portion of survivors negatively. There are a fair amount of survivors with powerful abusers protected by governments and the corporate press. If a survivor cannot speak to the press about their abuse, the only place they can go is online, directly or indirectly through an independent journalist who also risks being censored. This scenario isn’t hard to imagine—it already happened in China. During #MeToo, a survivor in China wanted to post their story. The government censored the post, so the survivor put their story on the blockchain. I’m excited that the survivor was creative and brave, but it’s terrifying to think that we live in a world where that situation is a necessity.
I believe that the future for many survivors sharing their stories globally will be on completely censorship-resistant and decentralized protocols. This thought in particular gives me hope. When we listen to the experiences of a diverse group of survivors, we can start to understand potential solutions to preventing the crimes from happening in the first place.
My heart is broken over the gut-wrenching stories of survivors sexually exploited online. Every time I hear the story of a survivor, I do think to myself quietly, “What could have prevented this from happening in the first place?” My heart is with survivors.
My head, on the other hand, is full of the understanding that the internet should remain free. The free flow of information should not be stopped. My mind is with the innocent citizens around the globe that deserve freedom both online and offline.
The problem is that governments don’t only want to censor illegal content that violates human rights—they create legislation that is so broad that it can impact speech and privacy of all. “Don’t you care about the kids?” Yes, I do. I do so much that I’m invested in finding solutions. I also care about all citizens around the globe that deserve an opportunity to live free from a mass surveillance society. If terrorism happens online, I should not be punished by losing my freedom. If drugs are sold online, I should not be punished. I’m not an abuser, I’m not a terrorist, and I don’t engage in illegal behaviors. I refuse to lose freedom because of others’ bad behaviors online.
I want to be clear that on a long enough timeline, the governments will decide that they can be better parents/caregivers than you can if something isn’t done to stop minors from being sexually exploited online. The price will be a complete loss of anonymity, privacy, free speech, and freedom of religion online. I find it rather insulting that governments think they’re better equipped to raise children than parents and caretakers.
So we can’t go backwards—all that we can do is go forward. Those who want to have freedom will find technology to facilitate their liberation. This will lead many over time to decentralized and open protocols. So as far as I’m concerned, this does solve a few of my worries—those who need, want, and deserve to speak freely online will have the opportunity in most countries—but what about online child sexual exploitation?
When I popped up around the decentralized space, I was met with the fear of censorship. I’m not here to censor you. I don’t write code. I couldn’t censor anyone or any piece of content even if I wanted to across the internet, no matter how depraved. I don’t have the skills to do that.
I’m here to start a conversation. Freedom comes at a cost. You must always fight for and protect your freedom. I can’t speak about protecting yourself from all of the Four Horsemen because I simply don’t know the topics well enough, but I can speak about this one topic.
If there was a shortcut to ending online child sexual exploitation, I would have found it by now. There isn’t one right now. I believe that education is the only pathway forward to preventing the crime of online child sexual exploitation for future generations.
I propose a yearly education course for every child of all school ages, taught as a standard part of the curriculum. Ideally, parents/caregivers would be involved in the education/learning process.
Course: - The creation of the internet and computers - The fight for cryptography - The tech supply chain from the ground up (example: human rights violations in the supply chain) - Corporate tech - Freedom tech - Data privacy - Digital privacy rights - AI (history-current) - Online safety (predators, scams, catfishing, extortion) - Bitcoin - Laws - How to deal with online hate and harassment - Information on who to contact if you are being abused online or offline - Algorithms - How to seek out the truth about news, etc., online
The parents/caregivers, homeschoolers, unschoolers, and those working to create decentralized parallel societies have been an inspiration while writing this, but my hope is that all children would learn this course, even in government ran schools. Ideally, parents would teach this to their own children.
The decentralized space doesn’t want child sexual exploitation to thrive. Here’s the deal: there has to be a strong prevention effort in order to protect the next generation. The internet isn’t going anywhere, predators aren’t going anywhere, and I’m not down to let anyone have the opportunity to prove that there is a need for more government. I don’t believe that the government should act as parents. The governments have had a chance to attempt to stop online child sexual exploitation, and they didn’t do it. Can we try a different pathway forward?
I’d like to put myself out of a job. I don’t want to ever hear another story like John Doe #1 ever again. This will require work. I’ve often called online child sexual exploitation the lynchpin for the internet. It’s time to arm generations of children with knowledge and tools. I can’t do this alone.
Individuals have fought so that I could have freedom online. I want to fight to protect it. I don’t want child predators to give the government any opportunity to take away freedom. Decentralized spaces are as close to a reset as we’ll get with the opportunity to do it right from the start. Start the youth off correctly by preventing potential hazards to the best of your ability.
The good news is anyone can work on this! I’d encourage you to take it and run with it. I added the additional education about the history of the internet to make the course more educational and fun. Instead of cleaning up generations of destroyed lives due to online sexual exploitation, perhaps this could inspire generations of those who will build our futures. Perhaps if the youth is armed with knowledge, they can create more tools to prevent the crime.
This one solution that I’m suggesting can be done on an individual level or on a larger scale. It should be adjusted depending on age, learning style, etc. It should be fun and playful.
This solution does not address abuse in the home or some of the root causes of offline child sexual exploitation. My hope is that it could lead to some survivors experiencing abuse in the home an opportunity to disclose with a trusted adult. The purpose for this solution is to prevent the crime of online child sexual exploitation before it occurs and to arm the youth with the tools to contact safe adults if and when it happens.
In closing, I went to hell a few times so that you didn’t have to. I spoke to the mothers of survivors of minors sexually exploited online—their tears could fill rivers. I’ve spoken with political dissidents who yearned to be free from authoritarian surveillance states. The only balance that I’ve found is freedom online for citizens around the globe and prevention from the dangers of that for the youth. Don’t slow down innovation and freedom. Educate, prepare, adapt, and look for solutions.
I’m not perfect and I’m sure that there are errors in this piece. I hope that you find them and it starts a conversation.

2025-03-15 23:00:40I want to see Nostr succeed. If you can think of a way I can help make that happen, I’m open to it. I’d like your suggestions.
My schedule’s shifting soon, and I could volunteer a few hours a week to a Nostr project. I won’t have more total time, but how I use it will change.
Why help? I care about freedom. Nostr’s one of the most powerful freedom tools I’ve seen in my lifetime. If I believe that, I should act on it.
I don’t care about money or sats. I’m not rich, I don’t have extra cash. That doesn’t drive me—freedom does. I’m volunteering, not asking for pay.
I’m not here for clout. I’ve had enough spotlight in my life; it doesn’t move me. If I wanted clout, I’d be on Twitter dropping basic takes. Clout’s easy. Freedom’s hard. I’d rather help anonymously. No speaking at events—small meetups are cool for the vibe, but big conferences? Not my thing. I’ll never hit a huge Bitcoin conference. It’s just not my scene.
That said, I could be convinced to step up if it’d really boost Nostr—as long as it’s legal and gets results.
In this space, I’d watch for social engineering. I watch out for it. I’m not here to make friends, just to help. No shade—you all seem great—but I’ve got a full life and awesome friends irl. I don’t need your crew or to be online cool. Connect anonymously if you want; I’d encourage it.
I’m sick of watching other social media alternatives grow while Nostr kinda stalls. I could trash-talk, but I’d rather do something useful.
Skills? I’m good at spotting social media problems and finding possible solutions. I won’t overhype myself—that’s weird—but if you’re responding, you probably see something in me. Perhaps you see something that I don’t see in myself.
If you need help now or later with Nostr projects, reach out. Nostr only—nothing else. Anonymous contact’s fine. Even just a suggestion on how I can pitch in, no project attached, works too. 💜
Creeps or harassment will get blocked or I’ll nuke my simplex code if it becomes a problem.
https://simplex.chat/contact#/?v=2-4&smp=smp%3A%2F%2FSkIkI6EPd2D63F4xFKfHk7I1UGZVNn6k1QWZ5rcyr6w%3D%40smp9.simplex.im%2FbI99B3KuYduH8jDr9ZwyhcSxm2UuR7j0%23%2F%3Fv%3D1-2%26dh%3DMCowBQYDK2VuAyEAS9C-zPzqW41PKySfPCEizcXb1QCus6AyDkTTjfyMIRM%253D%26srv%3Djssqzccmrcws6bhmn77vgmhfjmhwlyr3u7puw4erkyoosywgl67slqqd.onion

2025-05-06 14:21:13A concepção popular de "anarquia" evoca frequentemente caos, colapso e violência. Mas e se anarquia significasse outra coisa? E se representasse um mundo onde as pessoas cooperam e se coordenam sem autoridades impostas? E se implicasse liberdade, ordem voluntária e resiliência—sem coerção?
Bitcoin é um dos raros exemplos funcionais de princípios anarquistas em acção. Não tem CEO, nem Estado, nem planeador central—e, no entanto, o sistema funciona. Faz cumprir regras. Propõe um novo modelo de governação e oferece uma exploração concreta do anarcocapitalismo.
Para o compreendermos, temos de mudar de perspectiva. Bitcoin não é apenas software ou um instrumento de investimento—é um sistema vivo: uma ordem espontânea.
Ordem Espontânea, Teoria dos Jogos e o Papel dos Incentivos Económicos
Na política e economia contemporâneas, presume-se geralmente que a ordem tem de vir de cima. Governos, corporações e burocracias são vistos como essenciais para organizar a sociedade em grande escala.
Mas esta crença nem sempre se verifica.
Os mercados surgem espontaneamente da troca. A linguagem evolui sem supervisão central. Projectos de código aberto prosperam graças a contribuições voluntárias. Nenhum destes sistemas precisa de um rei—e, no entanto, têm estrutura e funcionam.
Bitcoin insere-se nesta tradição de ordens emergentes. Não é ditado por uma entidade única, mas é governado através de código, consenso dos utilizadores e incentivos económicos que recompensam a cooperação e penalizam a desonestidade.
Código Como Constituição
Bitcoin funciona com base num conjunto de regras de software transparentes e verificáveis. Estas regras determinam quem pode adicionar blocos, com que frequência, o que constitui uma transacção válida e como são criadas novas moedas.
Estas regras não são impostas por exércitos nem pela polícia. São mantidas por uma rede descentralizada de milhares de nós, cada um a correr voluntariamente software que valida o cumprimento das regras. Se alguém tentar quebrá-las, o resto da rede simplesmente rejeita a sua versão.
Isto não é governo por maioria—é aceitação baseada em regras.
Cada operador de nó escolhe qual versão do software quer executar. Se uma alteração proposta não tiver consenso suficiente, não se propaga. Foi assim que as "guerras do tamanho do bloco" foram resolvidas—não por votação, mas através de sinalização do que os utilizadores estavam dispostos a aceitar.
Este modelo de governação ascendente é voluntário, sem permissões, e extraordinariamente resiliente. Representa um novo paradigma de sistemas autorregulados.
Mineiros, Incentivos e a Segurança Baseada na Teoria dos Jogos
Bitcoin assegura a sua rede utilizando a Teoria de Jogos. Os mineiros que seguem o protocolo são recompensados financeiramente. Quem tenta enganar—como reescrever blocos ou gastar duas vezes—sofre perdas financeiras e desperdiça recursos.
Agir honestamente é mais lucrativo.
A genialidade de Bitcoin está em alinhar incentivos egoístas com o bem comum. Elimina a necessidade de confiar em administradores ou esperar benevolência. Em vez disso, torna a fraude economicamente irracional.
Isto substitui o modelo tradicional de "confiar nos líderes" por um mais robusto: construir sistemas onde o mau comportamento é desencorajado por design.
Isto é segurança anarquista—não a ausência de regras, mas a ausência de governantes.
Associação Voluntária e Confiança Construída em Consenso
Qualquer pessoa pode usar Bitcoin. Não há controlo de identidade, nem licenças, nem processo de aprovação. Basta descarregar o software e começar a transaccionar.
Ainda assim, Bitcoin não é um caos desorganizado. Os utilizadores seguem regras rigorosas do protocolo. Porquê? Porque é o consenso que dá valor às "moedas". Sem ele, a rede fragmenta-se e falha.
É aqui que Bitcoin desafia as ideias convencionais sobre anarquia. Mostra que sistemas voluntários podem gerar estabilidade—não porque as pessoas são altruístas, mas porque os incentivos bem desenhados tornam a cooperação a escolha racional.
Bitcoin é sem confiança (trustless), mas promove confiança.
Uma Prova de Conceito Viva
Muitos acreditam que, sem controlo central, a sociedade entraria em colapso. Bitcoin prova que isso não é necessariamente verdade.
É uma rede monetária global, sem permissões, capaz de fazer cumprir direitos de propriedade, coordenar recursos e resistir à censura—sem uma autoridade central. Baseia-se apenas em regras, incentivos e participação voluntária.
Bitcoin não é um sistema perfeito. É um projecto dinâmico, em constante evolução. Mas isso faz parte do que o torna tão relevante: é real, está a funcionar e continua a melhorar.
Conclusão
A anarquia não tem de significar caos. Pode significar cooperação sem coerção. Bitcoin prova isso.
Procuramos, desesperados, por alternativas às instituições falhadas, inchadas e corruptas. Bitcoin oferece mais do que dinheiro digital. É uma prova viva de que podemos construir sociedades descentralizadas, eficientes e justas.
E isso, por si só, já é revolucionário.

2025-05-06 14:10:48Bitcoin has been gaining increasing acceptance as a means of payment, evolving from being just a digital investment asset to becoming a viable alternative to traditional currencies. Today, many companies around the world already accept Bitcoin, providing consumers with greater financial freedom and reducing reliance on traditional banking intermediaries.
- Global companies that accept Bitcoin
Over the years, several well-known companies have begun accepting Bitcoin, recognizing its benefits such as security, transparency, and low transaction fees. Among the most prominent are:
01 - Microsoft: The tech giant allows users to add funds to their Microsoft accounts using Bitcoin. This enables the purchase of digital content such as games, apps, and software available in the Microsoft Store. 02 - Overstock: One of the largest online retailers that accepts Bitcoin for the purchase of furniture, electronics, and home goods. Overstock was an early adopter, signaling a strong commitment to financial innovation. 03 - AT&T: The U.S. telecommunications company was the first in its industry to accept Bitcoin payments, giving customers the option to pay their bills with cryptocurrency through BitPay. 04 - Twitch: While Twitch does not natively support Bitcoin donations or payments, many streamers use third-party services like NOWPayments, Streamlabs (with Coinbase integration), or Plisio to accept crypto tips and donations. This opens a path for Bitcoin support through external platforms, especially within the content creator community. 05 - Namecheap: A leading domain registrar and web hosting provider that accepts Bitcoin for domain registration and hosting services, showcasing Bitcoin’s usefulness in the digital economy.
- Small businesses and local commerce
Beyond large corporations, a growing number of small businesses and local merchants are embracing Bitcoin, particularly in cities that are becoming hubs for digital innovation.
01 - Restaurants and cafés: In cities like Lisbon, London, and New York, several cafés and eateries accept Bitcoin as payment, attracting tech-savvy customers. 02 - Hotels and tourism: Certain hotel chains and travel platforms now accept Bitcoin, simplifying bookings and removing the need for currency exchange for international travelers. 03 - Online stores: Many small e-commerce businesses offer Bitcoin as a payment option or even operate exclusively using cryptocurrency, benefiting from borderless, fast transactions.
- Advantages for businesses and consumers
The growing acceptance of Bitcoin is largely driven by its advantages:
01 - Lower transaction fees: Businesses can reduce costs associated with credit card fees and payment processors. 02 - No intermediaries: Direct peer-to-peer payments cut down on bureaucracy and reduce fraud risks. 03 - Global access: Bitcoin allows for cross-border payments without the need for currency exchange, ideal for international transactions.
In summary, the adoption of Bitcoin as a means of payment continues to expand, with companies of all sizes recognizing its strategic value. From large enterprises to independent creators and local shops, Bitcoin is gradually becoming a more practical and accepted financial tool. While challenges such as volatility and regulatory uncertainty remain, the broader trend points toward a future where paying with Bitcoin could be a common part of everyday life.
Thank you very much for reading this far. I hope everything is well with you, and sending a big hug from your favorite Bitcoiner maximalist from Madeira. Long live freedom!

2025-03-13 19:39:28In 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.

2025-05-06 14:05:40If you're an engineer stepping into the Bitcoin space from the broader crypto ecosystem, you're probably carrying a mental model shaped by speed, flexibility, and rapid innovation. That makes sense—most blockchain platforms pride themselves on throughput, programmability, and dev agility.
But Bitcoin operates from a different set of first principles. It’s not competing to be the fastest network or the most expressive smart contract platform. It’s aiming to be the most credible, neutral, and globally accessible value layer in human history.
Here’s why that matters—and why Bitcoin is not just an alternative crypto asset, but a structural necessity in the global financial system.
1. Bitcoin Fixes the Triffin Dilemma—Not With Policy, But Protocol
The Triffin Dilemma shows us that any country issuing the global reserve currency must run persistent deficits to supply that currency to the world. That’s not a flaw of bad leadership—it’s an inherent contradiction. The U.S. must debase its own monetary integrity to meet global dollar demand. That’s a self-terminating system.
Bitcoin sidesteps this entirely by being:
- Non-sovereign – no single nation owns it
- Hard-capped – no central authority can inflate it
- Verifiable and neutral – anyone with a full node can enforce the rules
In other words, Bitcoin turns global liquidity into an engineering problem, not a political one. No other system, fiat or crypto, has achieved that.
2. Bitcoin’s “Ossification” Is Intentional—and It's a Feature
From the outside, Bitcoin development may look sluggish. Features are slow to roll out. Code changes are conservative. Consensus rules are treated as sacred.
That’s the point.
When you’re building the global monetary base layer, stability is not a weakness. It’s a prerequisite. Every other financial instrument, app, or protocol that builds on Bitcoin depends on one thing: assurance that the base layer won’t change underneath them without extreme scrutiny.
So-called “ossification” is just another term for predictability and integrity. And when the market does demand change (SegWit, Taproot), Bitcoin’s soft-fork governance process has proven capable of deploying it safely—without coercive central control.
3. Layered Architecture: Throughput Is Not a Base Layer Concern
You don’t scale settlement at the base layer. You build layered systems. Just as TCP/IP doesn't need to carry YouTube traffic directly, Bitcoin doesn’t need to process every microtransaction.
Instead, it anchors:
- Lightning (fast payments)
- Fedimint (community custody)
- Ark (privacy + UTXO compression)
- Statechains, sidechains, and covenants (coming evolution)
All of these inherit Bitcoin’s security and scarcity, while handling volume off-chain, in ways that maintain auditability and self-custody.
4. Universal Assayability Requires Minimalism at the Base Layer
A core design constraint of Bitcoin is that any participant, anywhere in the world, must be able to independently verify the validity of every transaction and block—past and present—without needing permission or relying on third parties.
This property is called assayability—the ability to “test” or verify the authenticity and integrity of received bitcoin, much like verifying the weight and purity of a gold coin.
To preserve this:
- The base layer must remain resource-light, so running a full node stays accessible on commodity hardware.
- Block sizes must remain small enough to prevent centralization of verification.
- Historical data must remain consistent and tamper-evident, enabling proof chains across time and jurisdiction.
Any base layer that scales by increasing throughput or complexity undermines this fundamental guarantee, making the network more dependent on trust and surveillance infrastructure.
Bitcoin prioritizes global verifiability over throughput—because trustless money requires that every user can check the money they receive.
5. Governance: Not Captured, Just Resistant to Coercion
The current controversy around

and proposals to limit inscriptions is instructive. Some prominent devs have advocated for changes to block content filtering. Others see it as overreach.Here's what matters:
- No single dev, or team, can force changes into the network. Period.
- Bitcoin Core is not “the source of truth.” It’s one implementation. If it deviates from market consensus, it gets forked, sidelined, or replaced.
- The economic majority—miners, users, businesses—enforce Bitcoin’s rules, not GitHub maintainers.
In fact, recent community resistance to perceived Core overreach only reinforces Bitcoin’s resilience. Engineers who posture with narcissistic certainty, dismiss dissent, or attempt to capture influence are routinely neutralized by the market’s refusal to upgrade or adopt forks that undermine neutrality or openness.
This is governance via credible neutrality and negative feedback loops. Power doesn’t accumulate in one place. It’s constantly checked by the network’s distributed incentives.
6. Bitcoin Is Still in Its Infancy—And That’s a Good Thing
You’re not too late. The ecosystem around Bitcoin—especially L2 protocols, privacy tools, custody innovation, and zero-knowledge integrations—is just beginning.
If you're an engineer looking for:
- Systems with global scale constraints
- Architectures that optimize for integrity, not speed
- Consensus mechanisms that resist coercion
- A base layer with predictable monetary policy
Then Bitcoin is where serious systems engineers go when they’ve outgrown crypto theater.
Take-away
Under realistic, market-aware assumptions—where:
- Bitcoin’s ossification is seen as a stability feature, not inertia,
- Market forces can and do demand and implement change via tested, non-coercive mechanisms,
- Proof-of-work is recognized as the only consensus mechanism resistant to fiat capture,
- Wealth concentration is understood as a temporary distribution effect during early monetization,
- Low base layer throughput is a deliberate design constraint to preserve verifiability and neutrality,
- And innovation is layered by design, with the base chain providing integrity, not complexity...
Then Bitcoin is not a fragile or inflexible system—it is a deliberately minimal, modular, and resilient protocol.
Its governance is not leaderless chaos; it's a negative-feedback structure that minimizes the power of individuals or institutions to coerce change. The very fact that proposals—like controversial OP_RETURN restrictions—can be resisted, forked around, or ignored by the market without breaking the system is proof of decentralized control, not dysfunction.
Bitcoin is an adversarially robust monetary foundation. Its value lies not in how fast it changes, but in how reliably it doesn't—unless change is forced by real, bottom-up demand and implemented through consensus-tested soft forks.
In this framing, Bitcoin isn't a slower crypto. It's the engineering benchmark for systems that must endure, not entertain.
Final Word
Bitcoin isn’t moving slowly because it’s dying. It’s moving carefully because it’s winning. It’s not an app platform or a sandbox. It’s a protocol layer for the future of money.
If you're here because you want to help build that future, you’re in the right place.

2025-05-06 13:41:50Bitcoin was created to offer a secure and decentralized alternative to traditional money, enabling financial transactions without the need for intermediaries. DeFi, on the other hand, emerged as an expansion of this concept, proposing decentralized financial services such as lending, exchanges, and yield generation. However, despite its promises of innovation, DeFi carries numerous risks, making it a dangerous bet for those who value the security of their Bitcoin.
What is DeFi?
DeFi refers to a set of financial applications that operate without the intermediation of banks or traditional institutions. These platforms use smart contracts to automate transactions, allowing anyone to access financial services without relying on third parties. In theory, DeFi promises greater financial freedom, but in practice it is full of risks, scams, and technical vulnerabilities that can compromise users' funds.
- The risks of DeFi for Bitcoin holders
Bitcoin is the most secure digital currency in the world, protected by a decentralized and censorship-resistant network. Unlike DeFi, which is still in an experimental phase and has already suffered numerous attacks, Bitcoin remains solid and reliable. When someone places Bitcoin in DeFi platforms, they give up the security of direct custody and trust weaker systems.
The main risks include:
01 - Hackers and code flaws: Smart contracts are written by programmers and may contain bugs that allow massive thefts. Over the years, billions of dollars have been lost due to vulnerabilities in DeFi platforms. 02 - Liquidation risks: Many DeFi applications operate on collateralization systems, where users lock Bitcoin to obtain loans. If the market becomes volatile, those Bitcoins can be liquidated at lower-than-expected prices, causing irreversible losses. 03 - Scams and rug pulls: DeFi is full of shady projects where creators vanish with users’ funds. Without regulation and without guarantees, those who deposit Bitcoin in these platforms may never recover their funds.
- Keeping Bitcoin safe is the best choice
Bitcoin was created to be self-custodied, meaning each user should have direct control over their funds without relying on third parties. By sending Bitcoin to DeFi platforms, that security is lost and the asset is exposed to unnecessary risks. The best way to protect Bitcoin is to store it in a secure wallet, preferably offline (cold storage), avoiding any exposure to smart contracts or vulnerable systems.
In summary, DeFi may seem innovative, but the risks far outweigh the potential benefits—especially for those who value Bitcoin's security. Instead of risking losing funds on insecure platforms, the wisest choice is to keep Bitcoin safely stored, ensuring its long-term preservation. While Bitcoin continues to be the best digital store of value in the world, DeFi remains an unstable and dangerous environment where few win and many end up losing.
Thank you very much for reading this far. I hope everything is well with you, and sending a big hug from your favorite Bitcoiner maximalist from Madeira. Long live freedom!

2025-03-12 00:40:25Before I saw those X right-wing political “influencers” parading their Epstein binders in that PR stunt, I’d already posted this on Nostr, an open protocol.
“Today, the world’s attention will likely fixate on Epstein, governmental failures in addressing horrific abuse cases, and the influential figures who perpetrate such acts—yet few will center the victims and survivors in the conversation. The survivors of Epstein went to law enforcement and very little happened. The survivors tried to speak to the corporate press and the corporate press knowingly covered for him. In situations like these social media can serve as one of the only ways for a survivor’s voice to be heard.
It’s becoming increasingly evident that the line between centralized corporate social media and the state is razor-thin, if it exists at all. Time and again, the state shields powerful abusers when it’s politically expedient to do so. In this climate, a survivor attempting to expose someone like Epstein on a corporate tech platform faces an uphill battle—there’s no assurance their voice would even break through. Their story wouldn’t truly belong to them; it’d be at the mercy of the platform, subject to deletion at a whim. Nostr, though, offers a lifeline—a censorship-resistant space where survivors can share their truths, no matter how untouchable the abuser might seem. A survivor could remain anonymous here if they took enough steps.
Nostr holds real promise for amplifying survivor voices. And if you’re here daily, tossing out memes, take heart: you’re helping build a foundation for those who desperately need to be heard.“
That post is untouchable—no CEO, company, employee, or government can delete it. Even if I wanted to, I couldn’t take it down myself. The post will outlive me on the protocol.
The cozy alliance between the state and corporate social media hit me hard during that right-wing X “influencer” PR stunt. Elon owns X. Elon’s a special government employee. X pays those influencers to post. We don’t know who else pays them to post. Those influencers are spurred on by both the government and X to manage the Epstein case narrative. It wasn’t survivors standing there, grinning for photos—it was paid influencers, gatekeepers orchestrating yet another chance to re-exploit the already exploited.
The bond between the state and corporate social media is tight. If the other Epsteins out there are ever to be unmasked, I wouldn’t bet on a survivor’s story staying safe with a corporate tech platform, the government, any social media influencer, or mainstream journalist. Right now, only a protocol can hand survivors the power to truly own their narrative.
I don’t have anything against Elon—I’ve actually been a big supporter. I’m just stating it as I see it. X isn’t censorship resistant and they have an algorithm that they choose not the user. Corporate tech platforms like X can be a better fit for some survivors. X has safety tools and content moderation, making it a solid option for certain individuals. Grok can be a big help for survivors looking for resources or support! As a survivor, you know what works best for you, and safety should always come first—keep that front and center.
That said, a protocol is a game-changer for cases where the powerful are likely to censor. During China's # MeToo movement, survivors faced heavy censorship on social media platforms like Weibo and WeChat, where posts about sexual harassment were quickly removed, and hashtags like # MeToo or "woyeshi" were blocked by government and platform filters. To bypass this, activists turned to blockchain technology encoding their stories—like Yue Xin’s open letter about a Peking University case—into transaction metadata. This made the information tamper-proof and publicly accessible, resisting censorship since blockchain data can’t be easily altered or deleted.
I posted this on X 2/28/25. I wanted to try my first long post on a nostr client. The Epstein cover up is ongoing so it’s still relevant, unfortunately.

2025-03-10 12:09:35At this point, we should be arresting, not firing, any FBI employee who delays, destroys, or withholds information on the Epstein case. There is ZERO explanation I will accept for redacting anything for “national security” reasons. A lot of Trump supporters are losing patience with Pam Bondi. I will give her the benefit of the doubt for now since the corruption within the whole security/intelligence apparatus of our country runs deep. However, let’s not forget that probably Trump’s biggest mistakes in his first term involved picking weak and easily corruptible (or blackmailable) officials. It seemed every month a formerly-loyal person did a complete 180 degree turn and did everything they could to screw him over, regardless of the betrayal’s effect on the country or whatever principles that person claimed to have. I think he’s fixed his screening process, but since we’re talking about the FBI, we know they have the power to dig up any dirt or blackmail material available, or just make it up. In the Epstein case, it’s probably better to go after Bondi than give up a treasure trove of blackmail material against the long list of members on his client list.

What keeps you in such position is a fear of having to sink or swim on your own. Instead you should have a greater fear of what will happen to you if you remain dependant on others for power. Your goal in every maneuver in life must be ownership, working the corner for yourself. When it is yours to lose -you are more motivated,more creative,more alive.

2025-05-06 13:01:45Bitcoin has revolutionized the way people conduct financial transactions worldwide. As a decentralized digital currency, it offers new opportunities for e-commerce payments and international money transfers. Its speed, security, and low costs make it an efficient alternative to traditional methods by eliminating intermediaries and facilitating global transactions.
Bitcoin in e-commerce
E-commerce has grown exponentially, and Bitcoin has emerged as an innovative solution for online payments. Large retailers and small businesses are starting to accept Bitcoin as a form of payment, offering benefits to both merchants and consumers.
- Advantages of Bitcoin for e-commerce:
01 - Low transaction fees: Unlike credit cards and payment platforms that charge high fees, Bitcoin transactions generally have lower costs. This benefits merchants, who can reduce expenses and offer more competitive prices to customers. 02 - Elimination of chargebacks: In traditional systems, chargebacks (forced refunds by banks or card operators) are a concern for merchants. Since Bitcoin transactions are irreversible, merchants avoid fraud and disputes. 03 - Global access: Anyone with internet access can pay with Bitcoin, regardless of their location. This allows businesses to expand their market internationally without relying on banks or local payment systems. 04 - Privacy and security: Bitcoin transactions protect user identity, offering greater privacy compared to credit card payments or bank transfers. Additionally, since there’s no need to share personal data, the risk of information theft is reduced.
- Challenges of using Bitcoin in e-commerce:
01 - Volatility: Bitcoin’s price can fluctuate rapidly, making it difficult to set fixed prices for products and services. However, some merchants use payment processors that instantly convert Bitcoin into fiat currency, minimizing this risk. 02 - Limited adoption: Despite its growth, Bitcoin acceptance is not yet universal. Many stores and popular platforms have not adopted it, which can make daily purchases difficult. 03 - Confirmation time: Although Bitcoin is faster than traditional bank transfers, confirmation times may vary depending on the network fee paid. Some solutions, such as the Lightning Network, are being developed to enable instant payments.
Bitcoin in money remittances
Sending money abroad has long been a bureaucratic, costly, and time-consuming process. Traditional services like banks and money transfer companies charge high fees and can take days to complete a transaction. Bitcoin, on the other hand, offers an efficient alternative for global remittances, allowing anyone to send and receive money quickly and affordably.
- Benefits of Bitcoin for remittances:
01 - Reduced costs: While banks and companies like Western Union charge high fees for international transfers, Bitcoin allows money to be sent with minimal costs, regardless of the amount or destination. 02 - Transaction speed: International bank transfers can take several days to complete, especially in countries with limited financial infrastructure. With Bitcoin, money can be sent anywhere in the world within minutes or hours. 03 - Global accessibility: In regions where the banking system is restricted or inefficient, Bitcoin enables people to receive money without depending on banks. This is particularly useful in developing countries where international remittances are an essential source of income. 04 - Independence from intermediaries: Bitcoin operates in a decentralized manner, with no need for banks or transfer companies. This means people can send money directly to friends and family without intermediaries.
- Challenges of Bitcoin remittances:
01 - Conversion to local currency: Although Bitcoin can be received instantly, many people still need to convert it into local currency for everyday use. This may involve additional costs and depend on the availability of exchange services. 02 - Adoption and knowledge: Not everyone understands how Bitcoin works, which can hinder its widespread adoption for remittances. However, growing financial education on the subject can help overcome this barrier. 03 - Regulations and restrictions: Some governments impose restrictions on Bitcoin usage, making remittances more complicated. The evolution of regulations may affect ease of use in certain countries.
In summary, Bitcoin is transforming e-commerce and money remittances around the world. Its ability to eliminate intermediaries, reduce costs, and provide fast and secure payments makes it a viable alternative to traditional financial systems.
In e-commerce, it benefits both merchants and consumers by lowering fees and enhancing privacy. In the remittance sector, it facilitates money transfers to any part of the world, especially for those living in countries with inefficient banking systems.
Despite the challenges, Bitcoin adoption continues to grow, driven by innovative solutions and recognition of its potential as a global payment method. As more businesses and individuals embrace this technology, its presence in e-commerce and international remittances will become increasingly relevant.

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

2025-03-04 17:00:18This piece is the first in a series that will focus on things I think are a priority if your focus is similar to mine: building a strong family and safeguarding their future.
Choosing the ideal place to raise a family is one of the most significant decisions you will ever make. For simplicity sake I will break down my thought process into key factors: strong property rights, the ability to grow your own food, access to fresh water, the freedom to own and train with guns, and a dependable community.
A Jurisdiction with Strong Property Rights
Strong property rights are essential and allow you to build on a solid foundation that is less likely to break underneath you. Regions with a history of limited government and clear legal protections for landowners are ideal. Personally I think the US is the single best option globally, but within the US there is a wide difference between which state you choose. Choose carefully and thoughtfully, think long term. Obviously if you are not American this is not a realistic option for you, there are other solid options available especially if your family has mobility. I understand many do not have this capability to easily move, consider that your first priority, making movement and jurisdiction choice possible in the first place.
Abundant Access to Fresh Water
Water is life. I cannot overstate the importance of living somewhere with reliable, clean, and abundant freshwater. Some regions face water scarcity or heavy regulations on usage, so prioritizing a place where water is plentiful and your rights to it are protected is critical. Ideally you should have well access so you are not tied to municipal water supplies. In times of crisis or chaos well water cannot be easily shutoff or disrupted. If you live in an area that is drought prone, you are one drought away from societal chaos. Not enough people appreciate this simple fact.
Grow Your Own Food
A location with fertile soil, a favorable climate, and enough space for a small homestead or at the very least a garden is key. In stable times, a small homestead provides good food and important education for your family. In times of chaos your family being able to grow and raise healthy food provides a level of self sufficiency that many others will lack. Look for areas with minimal restrictions, good weather, and a culture that supports local farming.
Guns
The ability to defend your family is fundamental. A location where you can legally and easily own guns is a must. Look for places with a strong gun culture and a political history of protecting those rights. Owning one or two guns is not enough and without proper training they will be a liability rather than a benefit. Get comfortable and proficient. Never stop improving your skills. If the time comes that you must use a gun to defend your family, the skills must be instinct. Practice. Practice. Practice.
A Strong Community You Can Depend On
No one thrives alone. A ride or die community that rallies together in tough times is invaluable. Seek out a place where people know their neighbors, share similar values, and are quick to lend a hand. Lead by example and become a good neighbor, people will naturally respond in kind. Small towns are ideal, if possible, but living outside of a major city can be a solid balance in terms of work opportunities and family security.
Let me know if you found this helpful. My plan is to break down how I think about these five key subjects in future posts.

2025-05-06 12:18:09Digital wallets are important tools for storing and managing Bitcoin. They allow people to keep their private keys, access their funds, and make transactions in a practical and secure way. However, with several types of wallets available and the risks of incorrect use, it is essential to understand their features and follow good security practices.
What is a digital wallet?
A digital wallet is a software or device that stores the private and public keys linked to Bitcoin. Simply put, it doesn’t “store” Bitcoin itself but provides secure access to the network to verify and sign transactions.
Private keys work like a secret password that allows spending Bitcoins, while public keys are like account numbers that can be shared to receive payments. Keeping the private key secure is very important, as whoever has access to it controls the funds.
- Types of Digital Wallets
There are different types of digital wallets, each with specific features that meet various needs, whether for daily use or long-term storage.
- Hot Wallets
Wallets connected to the internet, designed for frequent use. Examples: Mobile apps, desktop wallets, online wallets.
Advantages:
01 - Accessible and easy to use 02 - Ideal for daily and quick transactions
Disadvantages:
01 - More exposed to cyberattacks such as phishing or hacking
- Cold Wallets
Wallets that keep private keys offline, increasing security. Examples: Hardware wallets, paper wallets, dedicated USB devices.
Advantages:
01 - High protection against hackers since they are not online 02 - Ideal for large amounts of Bitcoin or long-term storage
Disadvantages:
01 - Less practical for daily use 02 - Can be physically damaged or lost if not handled carefully
- Hardware Wallets
Physical devices, like Ledger or Trezor, that store private keys offline.
Advantages:
01 - Easy-to-use and secure interface 02 - Resistant to viruses and online attacks
Disadvantages:
01 - Higher initial cost 02 - Require care to avoid physical damage
- Paper Wallets
Involve printing or writing down private and public keys on a piece of paper.
Advantages:
01 - Completely offline and immune to digital attacks 02 - Simple and low-cost
Disadvantages:
01 - Vulnerable to physical damage such as water, fire, or loss 02 - Difficult to recover if lost
- Security in Digital Wallets
Protecting a digital wallet is essential to safeguard your Bitcoins from loss or theft.
Below are important practices to improve security:
- Private Key Protection
01 - Never share your private key with anyone 02 - Keep backup copies of the private key or recovery phrase in safe places
- Use of Recovery Phrases
The seed phrase is a sequence of 12 to 24 words that helps recover funds if the wallet is lost.
01 - Store the seed phrase offline and avoid taking pictures or saving it on internet-connected devices
- Two-Factor Authentication (2FA)
01 - Whenever possible, enable 2FA to protect accounts linked to online wallets or exchanges 02 - This adds an extra layer of security by requiring a second code to log in
- Updates and Maintenance
Keep the wallet software up to date to ensure protection against vulnerabilities
01 - Use only wallets from trustworthy and reputable developers
- Choosing the Right Wallet According to Need
01 - For frequent transactions, choose hot wallets but keep only small amounts 02 - For large amounts, use cold wallets like hardware or paper wallets, which are more secure
Risks and How to Avoid Them
- Hacker Attacks
Risk: Unauthorized access to hot wallets connected to the internet Prevention: Use cold wallets for storing large amounts and avoid clicking on suspicious links
- Loss of Access
Risk: Loss of private keys or the recovery phrase, making funds unrecoverable Prevention: Regularly make backups and store information in secure places
- Social Engineering and Phishing
Risk: Hackers trick people into giving up their private keys or personal information Prevention: Be suspicious of messages or websites that request your private keys. Never share sensitive data
- Physical Failures
Risk: Damage to devices or loss of paper wallets Prevention: Store backups in locations resistant to water, fire, and other threats
In summary, digital wallets are essential for the security and use of Bitcoin. Choosing the right wallet and following good security practices are key steps to protecting your assets.
Hot wallets offer convenience for daily use, while cold wallets provide strong security for long-term storage. Regardless of the type you choose, taking care of your private keys and recovery phrase is fundamental to ensure your Bitcoin remains under your control.
By understanding the types of wallets and implementing appropriate security measures, users can safely and efficiently take advantage of Bitcoin, maximizing the benefits of this digital revolution.

2025-02-27 21:32:12GA, plebs. The latest episode of Bitcoin And is out, and, as always, the chicanery is running rampant. Let’s break down the biggest topics I covered, and if you want the full, unfiltered rant, make sure to listen to the episode linked below.
House Democrats’ MEME Act: A Bad Joke?
House Democrats are proposing a bill to ban presidential meme coins, clearly aimed at Trump’s and Melania’s ill-advised token launches. While grifters launching meme coins is bad, this bill is just as ridiculous. If this legislation moves forward, expect a retaliatory strike exposing how politicians like Pelosi and Warren mysteriously amassed their fortunes. Will it pass? Doubtful. But it’s another sign of the government’s obsession with regulating everything except itself.
Senate Banking’s First Digital Asset Hearing: The Real Target Is You
Cynthia Lummis chaired the first digital asset hearing, and—surprise!—it was all about control. The discussion centered on stablecoins, AML, and KYC regulations, with witnesses suggesting Orwellian measures like freezing stablecoin transactions unless pre-approved by authorities. What was barely mentioned? Bitcoin. They want full oversight of stablecoins, which is really about controlling financial freedom. Expect more nonsense targeting self-custody wallets under the guise of stopping “bad actors.”
Bank of America and PayPal Want In on Stablecoins
Bank of America’s CEO openly stated they’ll launch a stablecoin as soon as regulation allows. Meanwhile, PayPal’s CEO paid for a hat using Bitcoin—not their own stablecoin, Pi USD. Why wouldn’t he use his own product? Maybe he knows stablecoins aren’t what they’re hyped up to be. Either way, the legacy financial system is gearing up to flood the market with stablecoins, not because they love crypto, but because it’s a tool to extend U.S. dollar dominance.
MetaPlanet Buys the Dip
Japan’s MetaPlanet issued $13.4M in bonds to buy more Bitcoin, proving once again that institutions see the writing on the wall. Unlike U.S. regulators who obsess over stablecoins, some companies are actually stacking sats.
UK Expands Crypto Seizure Powers
Across the pond, the UK government is pushing legislation to make it easier to seize and destroy crypto linked to criminal activity. While they frame it as going after the bad guys, it’s another move toward centralized control and financial surveillance.
Bitcoin Tools & Tech: Arc, SatoChip, and Nunchuk
Some bullish Bitcoin developments: ARC v0.5 is making Bitcoin’s second layer more efficient, SatoChip now supports Taproot and Nostr, and Nunchuk launched a group wallet with chat, making multisig collaboration easier.
The Bottom Line
The state is coming for financial privacy and control, and stablecoins are their weapon of choice. Bitcoiners need to stay focused, keep their coins in self-custody, and build out parallel systems. Expect more regulatory attacks, but don’t let them distract you—just keep stacking and transacting in ways they can’t control.

2025-02-25 15:20:39If you don't know where your posts are, you might as well just stay in the centralized Twitter. You either take control of your relay lists, or they will control you. Amethyst offers several lists of relays for our users. We are going to go one by one to help clarify what they are and which options are best for each one.
Public Home/Outbox Relays
Home relays store all YOUR content: all your posts, likes, replies, lists, etc. It's your home. Amethyst will send your posts here first. Your followers will use these relays to get new posts from you. So, if you don't have anything there, they will not receive your updates.
Home relays must allow queries from anyone, ideally without the need to authenticate. They can limit writes to paid users without affecting anyone's experience.
This list should have a maximum of 3 relays. More than that will only make your followers waste their mobile data getting your posts. Keep it simple. Out of the 3 relays, I recommend: - 1 large public, international relay: nos.lol, nostr.mom, relay.damus.io, etc. - 1 personal relay to store a copy of all your content in a place no one can delete. Go to relay.tools and never be censored again. - 1 really fast relay located in your country: paid options like http://nostr.wine are great
Do not include relays that block users from seeing posts in this list. If you do, no one will see your posts.
Public Inbox Relays
This relay type receives all replies, comments, likes, and zaps to your posts. If you are not getting notifications or you don't see replies from your friends, it is likely because you don't have the right setup here. If you are getting too much spam in your replies, it's probably because your inbox relays are not protecting you enough. Paid relays can filter inbox spam out.
Inbox relays must allow anyone to write into them. It's the opposite of the outbox relay. They can limit who can download the posts to their paid subscribers without affecting anyone's experience.
This list should have a maximum of 3 relays as well. Again, keep it small. More than that will just make you spend more of your data plan downloading the same notifications from all these different servers. Out of the 3 relays, I recommend: - 1 large public, international relay: nos.lol, nostr.mom, relay.damus.io, etc. - 1 personal relay to store a copy of your notifications, invites, cashu tokens and zaps. - 1 really fast relay located in your country: go to nostr.watch and find relays in your country
Terrible options include: - nostr.wine should not be here. - filter.nostr.wine should not be here. - inbox.nostr.wine should not be here.
DM Inbox Relays
These are the relays used to receive DMs and private content. Others will use these relays to send DMs to you. If you don't have it setup, you will miss DMs. DM Inbox relays should accept any message from anyone, but only allow you to download them.
Generally speaking, you only need 3 for reliability. One of them should be a personal relay to make sure you have a copy of all your messages. The others can be open if you want push notifications or closed if you want full privacy.
Good options are: - inbox.nostr.wine and auth.nostr1.com: anyone can send messages and only you can download. Not even our push notification server has access to them to notify you. - a personal relay to make sure no one can censor you. Advanced settings on personal relays can also store your DMs privately. Talk to your relay operator for more details. - a public relay if you want DM notifications from our servers.
Make sure to add at least one public relay if you want to see DM notifications.
Private Home Relays
Private Relays are for things no one should see, like your drafts, lists, app settings, bookmarks etc. Ideally, these relays are either local or require authentication before posting AND downloading each user\'s content. There are no dedicated relays for this category yet, so I would use a local relay like Citrine on Android and a personal relay on relay.tools.
Keep in mind that if you choose a local relay only, a client on the desktop might not be able to see the drafts from clients on mobile and vice versa.
Search relays:
This is the list of relays to use on Amethyst's search and user tagging with @. Tagging and searching will not work if there is nothing here.. This option requires NIP-50 compliance from each relay. Hit the Default button to use all available options on existence today: - nostr.wine - relay.nostr.band - relay.noswhere.com
Local Relays:
This is your local storage. Everything will load faster if it comes from this relay. You should install Citrine on Android and write ws://localhost:4869 in this option.
General Relays:
This section contains the default relays used to download content from your follows. Notice how you can activate and deactivate the Home, Messages (old-style DMs), Chat (public chats), and Global options in each.
Keep 5-6 large relays on this list and activate them for as many categories (Home, Messages (old-style DMs), Chat, and Global) as possible.
Amethyst will provide additional recommendations to this list from your follows with information on which of your follows might need the additional relay in your list. Add them if you feel like you are missing their posts or if it is just taking too long to load them.
My setup
Here's what I use: 1. Go to relay.tools and create a relay for yourself. 2. Go to nostr.wine and pay for their subscription. 3. Go to inbox.nostr.wine and pay for their subscription. 4. Go to nostr.watch and find a good relay in your country. 5. Download Citrine to your phone.
Then, on your relay lists, put:
Public Home/Outbox Relays: - nostr.wine - nos.lol or an in-country relay. -
.nostr1.com Public Inbox Relays - nos.lol or an in-country relay -
.nostr1.com DM Inbox Relays - inbox.nostr.wine -
.nostr1.com Private Home Relays - ws://localhost:4869 (Citrine) -
.nostr1.com (if you want) Search Relays - nostr.wine - relay.nostr.band - relay.noswhere.com
Local Relays - ws://localhost:4869 (Citrine)
General Relays - nos.lol - relay.damus.io - relay.primal.net - nostr.mom
And a few of the recommended relays from Amethyst.
Final Considerations
Remember, relays can see what your Nostr client is requesting and downloading at all times. They can track what you see and see what you like. They can sell that information to the highest bidder, they can delete your content or content that a sponsor asked them to delete (like a negative review for instance) and they can censor you in any way they see fit. Before using any random free relay out there, make sure you trust its operator and you know its terms of service and privacy policies.

2025-02-14 18:07:10Vice President J.D. Vance addressed the Munich Security Conference, criticizing European leaders for undermining free speech and traditional values. He claimed that the biggest threat to Europe is not from external enemies but from internal challenges. Vance condemned the arrest of a British man for praying near an abortion clinic and accused European politicians of censorship.
He urged leaders to combat illegal immigration and questioned their democratic practices. “There is a new sheriff in town,” he said, referring to President Trump. Vance's remarks were unexpected, as many anticipated discussions on security or Ukraine. His speech emphasized the need for Europe to share the defense burden to ensure stability and security.

2025-02-13 06:16:49My favorite line in any Marvel movie ever is in “Captain America.” After Captain America launches seemingly a hopeless assault on Red Skull’s base and is captured, we get this line:
“Arrogance may not be a uniquely American trait, but I must say, you do it better than anyone.”
Yesterday, I came across a comment on the song Devil Went Down to Georgia that had a very similar feel to it:
America has seemingly always been arrogant, in a uniquely American way. Manifest Destiny, for instance. The rest of the world is aware of this arrogance, and mocks Americans for it. A central point in modern US politics is the deriding of racist, nationalist, supremacist Americans.
That’s not what I see. I see American Arrogance as not only a beautiful statement about what it means to be American. I see it as an ode to the greatness of humanity in its purest form.
For most countries, saying “our nation is the greatest” is, in fact, twinged with some level of racism. I still don’t have a problem with it. Every group of people should be allowed to feel pride in their accomplishments. The destruction of the human spirit since the end of World War 2, where greatness has become a sin and weakness a virtue, has crushed the ability of people worldwide to strive for excellence.
But I digress. The fears of racism and nationalism at least have a grain of truth when applied to other nations on the planet. But not to America.
That’s because the definition of America, and the prototype of an American, has nothing to do with race. The definition of Americanism is freedom. The founding of America is based purely on liberty. On the God-given rights of every person to live life the way they see fit.
American Arrogance is not a statement of racial superiority. It’s barely a statement of national superiority (though it absolutely is). To me, when an American comments on the greatness of America, it’s a statement about freedom. Freedom will always unlock the greatness inherent in any group of people. Americans are definitionally better than everyone else, because Americans are freer than everyone else. (Or, at least, that’s how it should be.)
In Devil Went Down to Georgia, Johnny is approached by the devil himself. He is challenged to a ridiculously lopsided bet: a golden fiddle versus his immortal soul. He acknowledges the sin in accepting such a proposal. And yet he says, “God, I know you told me not to do this. But I can’t stand the affront to my honor. I am the greatest. The devil has nothing on me. So God, I’m gonna sin, but I’m also gonna win.”

2025-05-06 11:54:39A few weeks ago, I ran into an old friend at a coffee shop. We hadn’t spoken in years, and within five minutes, she said something I’ve heard countless times:
“I just feel like I’m so behind.”
Behind who? Behind what?
There’s this idea—quiet, nagging, oddly universal—that we’re all somehow in a race we didn’t sign up for. That we’re supposed to have hit certain milestones by certain ages. That if we’re not married, promoted, rich, settled, happy (and photogenic) by 30 or 40 or pick your poison, then we’ve failed some invisible test.
Where did this come from?
Some of it’s cultural, obviously. Social media compresses timelines. You’re 27, doom-scrolling, and suddenly someone from high school just IPO’d their startup and got engaged in Rome. Another just bought a house with a kitchen island the size of a small country. You wonder if you missed a memo.
But beneath that, there’s something deeper. A belief that life is linear. That it should look like a staircase: school, job, marriage, house, kids, success. But real life? It’s a squiggle. A mess. A beautiful disaster.
Here’s the truth: You’re not behind. There’s no schedule. There’s only your path, and the courage it takes to stay on it—even when it looks wildly different from everyone else’s.
I say this as someone who has taken the “scenic route.” I changed careers in my 30s. I moved cities on a hunch. I dropped things that looked great on paper because they felt wrong in my gut. I’ve had seasons of momentum and seasons of stuckness. Both were necessary.
“Catching up” assumes there’s a fixed destination. But what if there isn’t? What if the point isn’t arrival, but presence? Progress that feels real, not performative?
If you need a permission slip to stop comparing, let this be it.
You’re not late. You’re not early.
You’re right on time. -

2025-05-06 11:54:36There’s something sacred about morning air — the way it carries just enough chill to remind you you’re alive, without pushing you back inside. I’ve been starting my days on the balcony lately. Not because it’s glamorous (it isn’t), or because I have a routine (I don’t), but because it’s the only space in my apartment that feels both open and still.
This morning I made coffee with too much cinnamon and curled up with a blanket that’s seen better days. I watched the city slowly wake up — one barking dog, two joggers, and the clatter of a recycling truck below. It’s odd how these tiny patterns become a kind of comfort.
I used to think that slowing down meant falling behind. But here, perched on the third floor with my feet on cold concrete and the sky just starting to blush, I feel like I’m exactly where I’m supposed to be.
If you’re reading this, maybe you needed that reminder too.

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

2025-02-05 17:47:16I got into a friendly discussion on X regarding health insurance. The specific question was how to deal with health insurance companies (presumably unfairly) denying claims? My answer, as usual: get government out of it!
The US healthcare system is essentially the worst of both worlds:
- Unlike full single payer, individuals incur high costs
- Unlike a true free market, regulation causes increases in costs and decreases competition among insurers
I'm firmly on the side of moving towards the free market. (And I say that as someone living under a single payer system now.) Here's what I would do:
- Get rid of tax incentives that make health insurance tied to your employer, giving individuals back proper freedom of choice.
- Reduce regulations significantly.
-
In the short term, some people will still get rejected claims and other obnoxious behavior from insurance companies. We address that in two ways:
- Due to reduced regulations, new insurance companies will be able to enter the market offering more reliable coverage and better rates, and people will flock to them because they have the freedom to make their own choices.
- Sue the asses off of companies that reject claims unfairly. And ideally, as one of the few legitimate roles of government in all this, institute new laws that limit the ability of fine print to allow insurers to escape their responsibilities. (I'm hesitant that the latter will happen due to the incestuous relationship between Congress/regulators and insurers, but I can hope.)
Will this magically fix everything overnight like politicians normally promise? No. But it will allow the market to return to a healthy state. And I don't think it will take long (order of magnitude: 5-10 years) for it to come together, but that's just speculation.
And since there's a high correlation between those who believe government can fix problems by taking more control and demanding that only credentialed experts weigh in on a topic (both points I strongly disagree with BTW): I'm a trained actuary and worked in the insurance industry, and have directly seen how government regulation reduces competition, raises prices, and harms consumers.
And my final point: I don't think any prior art would be a good comparison for deregulation in the US, it's such a different market than any other country in the world for so many reasons that lessons wouldn't really translate. Nonetheless, I asked Grok for some empirical data on this, and at best the results of deregulation could be called "mixed," but likely more accurately "uncertain, confused, and subject to whatever interpretation anyone wants to apply."

2025-05-06 11:54:14May 6 marks my "Nostr birthday." This means I've been on Nostr for two years now. See my initial "Running nostr" note timestamped and archived on the Hive blockchain at https://peakd.com/bitcoin/@crrdlx/running-nostr
Two years ago, I really had no idea what Nostr was. I was asking, "What is this Nostr thing?"
And, I had no idea what I was doing then while using the front end clients. The clients were clunky and since the protocol was rather plastic (still kinda is). As evidence to my ignorance, the spinning wheels on Coracle.social just kept spinning. I didn't realize that since I was only following two people, one being myself, there was nothing to load from relays except my one "Running nostr" note. Hence, the Coracle wheels just spun in their mesmerizing manner. At least they're soothing to watch.
Yet, despite my ignorance, I had an inkling of a notion that Nostr was indeed something different, maybe special. Otherwise, I wouldn't have taken the time to capture an animated gif and make that Hive post to chronicle my first Nostr note.
For fun, I made another "Running nostr" note yesterday using Coracle.social. It still has those muted, earthy tones, but the wheels are not there anymore for long. Coracle, like Nostr, has come a long way in two years. It loads much faster now, which means less wheel spinning. I kind of miss the wheels for some reason, they build the drama and expectation of what might appear.

2025-05-06 11:06:40Music has always been dynamic, molding and reflecting cultural shifts across generations. From the smoky underground clubs of Northern England to the gritty, graffiti-laden walls of New York City's punk venues, and the rain-soaked streets of Seattle, the evolution of music is a testament to the ever-changing landscape of human expression. Daniel Siegel Alonso takes you on a witty and insightful journey through pivotal moments in music history: The Beatles at The Cavern Club, punk rock's birth at CBGBs, and the Seattle grunge explosion.
The Beatles do The Cavern
Close your eyes and imagine: It's 1961, and you're down in the basement of The Cavern Club in Liverpool; it's packed with sweat-drenched, eager faces, and the air thick, dripping with anticipation. On stage, four young lads who would soon become the most famous band in the world are tuning their guitars. The Beatles, with their mop-top haircuts and cheeky grins, are on the precipice of changing music for generations.
Before they were household names, John, Paul, George, and Ringo honed their craft in this humble, dimly lit venue. The Cavern Club was their proving ground, where they transitioned from covering American icons Chuck Berry and Little Richard to showcasing their original material. Here, they first captivated audiences with their infectious energy and groundbreaking sound.
The group's time at The Cavern Club was pivotal. It was where they caught the eye of Brian Epstein, who would become its manager, and later, record producer George Martin, aka the fifth Beatle. This tiny, subterranean venue was the launchpad for a nuclear cultural revolution. The Beatles didn't just play pop and rock music; they constructed an identity, a lifestyle, and, in hindsight, an era. They embodied the spirit of the Swinging 60s, melding rock 'n' roll with a bouncy pop sensibility that was both rowdy and charming.
Anarchy in the Big Apple
Daniel Siegel Alonso fast-forwards to the mid-70s, and we're in an entirely different world. Bankrupt Manhattan, in the bowels of a biker bar on the Bowery called CBGBs--a mouthful of an acronym standing for Country, Bluegrass, and Blues. The stage is dilapidated, and the sound system is a haphazard collection of amps and speakers at best. Here, the raw energy of punk rock was born, thrashing and pogoing its way into the mainstream.
CBGBs became the center of a musical revolt. Groups like The Ramones, Blondie, and Television took to the ramshackle stage, bringing with them a loud, fast, and unapologetically raw sound. Punk was a direct response to the bloated excesses of middle-of-the-road rock and bands like Yes, Chicago, and Fleetwood Mac; punk was do-it-yourself, back to basics, and in-your-face.
The Ramones epitomized this new angsty attitude with their black leather jackets and torn jeans. The songs they wrote were short, sharp, and shocking to audiences accustomed to indulgent guitar solos and elaborate stage productions. CBGBs was more than just a venue; it was a breeding ground for a cultural movement. It embraced the DIY ethic, encouraging emerging bands to play regardless of polish or professionalism. This sense of independence and defiance reverberated with a new generation of listeners disenchanted by the status quo.
The Last Great Rock Revolution
Siegel Alonso jumps ahead another decade to Seattle, a city known more for its rain than its rock-and-roll. Yet, over three decades ago, Seattle was the epicenter of grunge, a new genre that would once again redefine music. The core of this movement was a collection of venues like The Crocodile and The Off Ramp, where bands like Nirvana, Pearl Jam, and Soundgarden first made their mark.
Grunge was a gritty, angst-filled reaction to the over-produced pop and ostentatious hair metal of the 80s. It combined the raw energy of punk from the previous decade with heavy metal's strength, birthing a sound that was both abrasive and softly melodic. Grunge poster boy Kurt Cobain, with his ragged sweaters and unkempt wiry hair, became the reluctant voice of the last analog generation. Nirvana's breakout album, "Nevermind," was a seismic pop culture event, forcing grunge into the global mainstream.
Seattle's grunge scene was characterized by authenticity and a sense of community. Bands often collaborated and supported each other, creating a tight-knit musical ecosystem. The city's isolation from traditional music industry hubs allowed for a unique sound to develop, one that was untainted by commercial pressures.
Connecting the Dots
What ties these three musical moments together is their grassroots beginnings. The Beatles, the first wave of punk rock, and grunge all began in small, dingy venues, driven by pure passion and a craving to disrupt the status quo. Each musical chapter mirrored and influenced the cultural zeitgeist of its time, providing a soundtrack to their respective eras' social changes and attitudes.
The Cavern Club, CBGBs, and Seattle's grunge venues were more than places where bands performed; they were incubators of innovation and rebellion. They nurtured the raw, unpolished energy that would shape the future of popular music.
As Siegel Alonso reflects on these musical milestones, a pattern of evolution emerges driven by a handful of fundamental ingredients: authenticity, community, and a bold embrace of the unknown. Music's narrative is one of constant change, and as these examples depict, it's often in the most unexpected places that the next big thing begins to take shape.

2025-02-04 08:29:00President Trump has started rolling out his tariffs, something I blogged about in November. People are talking about these tariffs a lot right now, with many people (correctly) commenting on how consumers will end up with higher prices as a result of these tariffs. While that part is true, I’ve seen a lot of people taking it to the next, incorrect step: that consumers will pay the entirety of the tax. I put up a poll on X to see what people thought, and while the right answer got a lot of votes, it wasn't the winner.
For purposes of this blog post, our ultimate question will be the following:
- Suppose apples currently sell for $1 each in the entire United States.
- There are domestic sellers and foreign sellers of apples, all receiving the same price.
- There are no taxes or tariffs on the purchase of apples.
- The question is: if the US federal government puts a $0.50 import tariff per apple, what will be the change in the following:
- Number of apples bought in the US
- Price paid by buyers for apples in the US
- Post-tax price received by domestic apple producers
- Post-tax price received by foreign apple producers
Before we can answer that question, we need to ask an easier, first question: before instituting the tariff, why do apples cost $1?
And finally, before we dive into the details, let me provide you with the answers to the ultimate question. I recommend you try to guess these answers before reading this, and if you get it wrong, try to understand why:
- The number of apples bought will go down
- The buyers will pay more for each apple they buy, but not the full amount of the tariff
- Domestic apple sellers will receive a higher price per apple
- Foreign apple sellers will receive a lower price per apple, but not lowered by the full amount of the tariff
In other words, regardless of who sends the payment to the government, both taxed parties (domestic buyers and foreign sellers) will absorb some of the costs of the tariff, while domestic sellers will benefit from the protectionism provided by tariffs and be able to sell at a higher price per unit.
Marginal benefit
All of the numbers discussed below are part of a helper Google Sheet I put together for this analysis. Also, apologies about the jagged lines in the charts below, I hadn’t realized before starting on this that there are some difficulties with creating supply and demand charts in Google Sheets.
Let’s say I absolutely love apples, they’re my favorite food. How much would I be willing to pay for a single apple? You might say “$1, that’s the price in the supermarket,” and in many ways you’d be right. If I walk into supermarket A, see apples on sale for $50, and know that I can buy them at supermarket B for $1, I’ll almost certainly leave A and go buy at B.
But that’s not what I mean. What I mean is: how high would the price of apples have to go everywhere so that I’d no longer be willing to buy a single apple? This is a purely personal, subjective opinion. It’s impacted by how much money I have available, other expenses I need to cover, and how much I like apples. But let’s say the number is $5.
How much would I be willing to pay for another apple? Maybe another $5. But how much am I willing to pay for the 1,000th apple? 10,000th? At some point, I’ll get sick of apples, or run out of space to keep the apples, or not be able to eat, cook, and otherwise preserve all those apples before they rot.
The point being: I’ll be progressively willing to spend less and less money for each apple. This form of analysis is called marginal benefit: how much benefit (expressed as dollars I’m willing to spend) will I receive from each apple? This is a downward sloping function: for each additional apple I buy (quantity demanded), the price I’m willing to pay goes down. This is what gives my personal demand curve. And if we aggregate demand curves across all market participants (meaning: everyone interested in buying apples), we end up with something like this:
Assuming no changes in people’s behavior and other conditions in the market, this chart tells us how many apples will be purchased by our buyers at each price point between $0.50 and $5. And ceteris paribus (all else being equal), this will continue to be the demand curve for apples.
Marginal cost
Demand is half the story of economics. The other half is supply, or: how many apples will I sell at each price point? Supply curves are upward sloping: the higher the price, the more a person or company is willing and able to sell a product.
Let’s understand why. Suppose I have an apple orchard. It’s a large property right next to my house. With about 2 minutes of effort, I can walk out of my house, find the nearest tree, pick 5 apples off the tree, and call it a day. 5 apples for 2 minutes of effort is pretty good, right?
Yes, there was all the effort necessary to buy the land, and plant the trees, and water them… and a bunch more than I likely can’t even guess at. We’re going to ignore all of that for our analysis, because for short-term supply-and-demand movement, we can ignore these kinds of sunk costs. One other simplification: in reality, supply curves often start descending before ascending. This accounts for achieving efficiencies of scale after the first number of units purchased. But since both these topics are unneeded for understanding taxes, I won’t go any further.
Anyway, back to my apple orchard. If someone offers me $0.50 per apple, I can do 2 minutes of effort and get $2.50 in revenue, which equates to a $75/hour wage for me. I’m more than happy to pick apples at that price!
However, let’s say someone comes to buy 10,000 apples from me instead. I no longer just walk out to my nearest tree. I’m going to need to get in my truck, drive around, spend the day in the sun, pay for gas, take a day off of my day job (let’s say it pays me $70/hour). The costs go up significantly. Let’s say it takes 5 days to harvest all those apples myself, it costs me $100 in fuel and other expenses, and I lose out on my $70/hour job for 5 days. We end up with:
- Total expenditure: $100 + $70 * 8 hours a day * 5 days \== $2900
- Total revenue: $5000 (10,000 apples at $0.50 each)
- Total profit: $2100
So I’m still willing to sell the apples at this price, but it’s not as attractive as before. And as the number of apples purchased goes up, my costs keep increasing. I’ll need to spend more money on fuel to travel more of my property. At some point I won’t be able to do the work myself anymore, so I’ll need to pay others to work on the farm, and they’ll be slower at picking apples than me (less familiar with the property, less direct motivation, etc.). The point being: at some point, the number of apples can go high enough that the $0.50 price point no longer makes me any money.
This kind of analysis is called marginal cost. It refers to the additional amount of expenditure a seller has to spend in order to produce each additional unit of the good. Marginal costs go up as quantity sold goes up. And like demand curves, if you aggregate this data across all sellers, you get a supply curve like this:
Equilibrium price
We now know, for every price point, how many apples buyers will purchase, and how many apples sellers will sell. Now we find the equilibrium: where the supply and demand curves meet. This point represents where the marginal benefit a buyer would receive from the next buyer would be less than the cost it would take the next seller to make it. Let’s see it in a chart:
You’ll notice that these two graphs cross at the $1 price point, where 63 apples are both demanded (bought by consumers) and supplied (sold by producers). This is our equilibrium price. We also have a visualization of the surplus created by these trades. Everything to the left of the equilibrium point and between the supply and demand curves represents surplus: an area where someone is receiving something of more value than they give. For example:
- When I bought my first apple for $1, but I was willing to spend $5, I made $4 of consumer surplus. The consumer portion of the surplus is everything to the left of the equilibrium point, between the supply and demand curves, and above the equilibrium price point.
- When a seller sells his first apple for $1, but it only cost $0.50 to produce it, the seller made $0.50 of producer surplus. The producer portion of the surplus is everything to the left of the equilibrium point, between the supply and demand curves, and below the equilibrium price point.
Another way of thinking of surplus is “every time someone got a better price than they would have been willing to take.”
OK, with this in place, we now have enough information to figure out how to price in the tariff, which we’ll treat as a negative externality.
Modeling taxes
Alright, the government has now instituted a $0.50 tariff on every apple sold within the US by a foreign producer. We can generally model taxes by either increasing the marginal cost of each unit sold (shifting the supply curve up), or by decreasing the marginal benefit of each unit bought (shifting the demand curve down). In this case, since only some of the producers will pay the tax, it makes more sense to modify the supply curve.
First, let’s see what happens to the foreign seller-only supply curve when you add in the tariff:
With the tariff in place, for each quantity level, the price at which the seller will sell is $0.50 higher than before the tariff. That makes sense: if I was previously willing to sell my 82nd apple for $3, I would now need to charge $3.50 for that apple to cover the cost of the tariff. We see this as the tariff “pushing up” or “pushing left” the original supply curve.
We can add this new supply curve to our existing (unchanged) supply curve for domestic-only sellers, and we end up with a result like this:
The total supply curve adds up the individual foreign and domestic supply curves. At each price point, we add up the total quantity each group would be willing to sell to determine the total quantity supplied for each price point. Once we have that cumulative supply curve defined, we can produce an updated supply-and-demand chart including the tariff:
As we can see, the equilibrium has shifted:
- The equilibrium price paid by consumers has risen from $1 to $1.20.
- The total number of apples purchased has dropped from 63 apples to 60 apples.
- Consumers therefore received 3 less apples. They spent $72 for these 60 apples, whereas previously they spent $63 for 3 more apples, a definite decrease in consumer surplus.
- Foreign producers sold 36 of those apples (see the raw data in the linked Google Sheet), for a gross revenue of $43.20. However, they also need to pay the tariff to the US government, which accounts for $18, meaning they only receive $25.20 post-tariff. Previously, they sold 42 apples at $1 each with no tariff to be paid, meaning they took home $42.
- Domestic producers sold the remaining 24 apples at $1.20, giving them a revenue of $28.80. Since they don’t pay the tariff, they take home all of that money. By contrast, previously, they sold 21 apples at $1, for a take-home of $21.
- The government receives $0.50 for each of the 60 apples sold, or in other words receives $30 in revenue it wouldn’t have received otherwise.
We could be more specific about the surpluses, and calculate the actual areas for consumer surplus, producer surplus, inefficiency from the tariff, and government revenue from the tariff. But I won’t bother, as those calculations get slightly more involved. Instead, let’s just look at the aggregate outcomes:
- Consumers were unquestionably hurt. Their price paid went up by $0.20 per apple, and received less apples.
- Foreign producers were also hurt. Their price received went down from the original $1 to the new post-tariff price of $1.20, minus the $0.50 tariff. In other words: foreign producers only receive $0.70 per apple now. This hurt can be mitigated by shifting sales to other countries without a tariff, but the pain will exist regardless.
- Domestic producers scored. They can sell less apples and make more revenue doing it.
- And the government walked away with an extra $30.
Hopefully you now see the answer to the original questions. Importantly, while the government imposed a $0.50 tariff, neither side fully absorbed that cost. Consumers paid a bit more, foreign producers received a bit less. The exact details of how that tariff was split across the groups is mediated by the relevant supply and demand curves of each group. If you want to learn more about this, the relevant search term is “price elasticity,” or how much a group’s quantity supplied or demanded will change based on changes in the price.
Other taxes
Most taxes are some kind of a tax on trade. Tariffs on apples is an obvious one. But the same applies to income tax (taxing the worker for the trade of labor for money) or payroll tax (same thing, just taxing the employer instead). Interestingly, you can use the same model for analyzing things like tax incentives. For example, if the government decided to subsidize domestic apple production by giving the domestic producers a $0.50 bonus for each apple they sell, we would end up with a similar kind of analysis, except instead of the foreign supply curve shifting up, we’d see the domestic supply curve shifting down.
And generally speaking, this is what you’ll always see with government involvement in the economy. It will result in disrupting an existing equilibrium, letting the market readjust to a new equilibrium, and incentivization of some behavior, causing some people to benefit and others to lose out. We saw with the apple tariff, domestic producers and the government benefited while others lost.
You can see the reverse though with tax incentives. If I give a tax incentive of providing a deduction (not paying income tax) for preschool, we would end up with:
- Government needs to make up the difference in tax revenue, either by raising taxes on others or printing more money (leading to inflation). Either way, those paying the tax or those holding government debased currency will pay a price.
- Those people who don’t use the preschool deduction will receive no benefit, so they simply pay a cost.
- Those who do use the preschool deduction will end up paying less on tax+preschool than they would have otherwise.
This analysis is fully amoral. It’s not saying whether providing subsidized preschool is a good thing or not, it simply tells you where the costs will be felt, and points out that such government interference in free economic choice does result in inefficiencies in the system. Once you have that knowledge, you’re more well educated on making a decision about whether the costs of government intervention are worth the benefits.

@ 288ebe67:fa8e3f31
2025-05-06 11:52:28A few weeks ago, I ran into an old friend at a coffee shop. We hadn’t spoken in years, and within five minutes, she said something I’ve heard countless times:
“I just feel like I’m so behind.”
Behind who? Behind what?
There’s this idea—quiet, nagging, oddly universal—that we’re all somehow in a race we didn’t sign up for. That we’re supposed to have hit certain milestones by certain ages. That if we’re not married, promoted, rich, settled, happy (and photogenic) by 30 or 40 or pick your poison, then we’ve failed some invisible test.
Where did this come from?
Some of it’s cultural, obviously. Social media compresses timelines. You’re 27, doom-scrolling, and suddenly someone from high school just IPO’d their startup and got engaged in Rome. Another just bought a house with a kitchen island the size of a small country. You wonder if you missed a memo.
But beneath that, there’s something deeper. A belief that life is linear. That it should look like a staircase: school, job, marriage, house, kids, success. But real life? It’s a squiggle. A mess. A beautiful disaster.
Here’s the truth: You’re not behind. There’s no schedule. There’s only your path, and the courage it takes to stay on it—even when it looks wildly different from everyone else’s.
I say this as someone who has taken the “scenic route.” I changed careers in my 30s. I moved cities on a hunch. I dropped things that looked great on paper because they felt wrong in my gut. I’ve had seasons of momentum and seasons of stuckness. Both were necessary.
“Catching up” assumes there’s a fixed destination. But what if there isn’t? What if the point isn’t arrival, but presence? Progress that feels real, not performative?
If you need a permission slip to stop comparing, let this be it.
You’re not late. You’re not early.
You’re right on time. -

2025-05-06 11:52:27There’s something sacred about morning air — the way it carries just enough chill to remind you you’re alive, without pushing you back inside. I’ve been starting my days on the balcony lately. Not because it’s glamorous (it isn’t), or because I have a routine (I don’t), but because it’s the only space in my apartment that feels both open and still.
This morning I made coffee with too much cinnamon and curled up with a blanket that’s seen better days. I watched the city slowly wake up — one barking dog, two joggers, and the clatter of a recycling truck below. It’s odd how these tiny patterns become a kind of comfort.
I used to think that slowing down meant falling behind. But here, perched on the third floor with my feet on cold concrete and the sky just starting to blush, I feel like I’m exactly where I’m supposed to be.
If you’re reading this, maybe you needed that reminder too.

2025-01-30 17:15:37There was a slight dust up recently over a website someone runs removing a listing for an app someone built based on entirely arbitrary criteria. I'm not to going to attempt to speak for either wounded party, but I would like to share my own personal definition for what constitutes a "nostr app" in an effort to help clarify what might be an otherwise confusing and opaque purity test.
In this post, I will be committing the "no true Scotsman" fallacy, in which I start with the most liberal definition I can come up with, and gradually refine it until all that is left is the purest, gleamingest, most imaginary and unattainable nostr app imaginable. As I write this, I wonder if anything built yet will actually qualify. In any case, here we go.
It uses nostr
The lowest bar for what a "nostr app" might be is an app ("application" - i.e. software, not necessarily a native app of any kind) that has some nostr-specific code in it, but which doesn't take any advantage of what makes nostr distinctive as a protocol.
Examples might include a scraper of some kind which fulfills its charter by fetching data from relays (regardless of whether it validates or retains signatures). Another might be a regular web 2.0 app which provides an option to "log in with nostr" by requesting and storing the user's public key.
In either case, the fact that nostr is involved is entirely neutral. A scraper can scrape html, pdfs, jsonl, whatever data source - nostr relays are just another target. Likewise, a user's key in this scenario is treated merely as an opaque identifier, with no appreciation for the super powers it brings along.
In most cases, this kind of app only exists as a marketing ploy, or less cynically, because it wants to get in on the hype of being a "nostr app", without the developer quite understanding what that means, or having the budget to execute properly on the claim.
It leverages nostr
Some of you might be wondering, "isn't 'leverage' a synonym for 'use'?" And you would be right, but for one connotative difference. It's possible to "use" something improperly, but by definition leverage gives you a mechanical advantage that you wouldn't otherwise have. This is the second category of "nostr app".
This kind of app gets some benefit out of the nostr protocol and network, but in an entirely selfish fashion. The intention of this kind of app is not to augment the nostr network, but to augment its own UX by borrowing some nifty thing from the protocol without really contributing anything back.
Some examples might include:
- Using nostr signers to encrypt or sign data, and then store that data on a proprietary server.
- Using nostr relays as a kind of low-code backend, but using proprietary event payloads.
- Using nostr event kinds to represent data (why), but not leveraging the trustlessness that buys you.
An application in this category might even communicate to its users via nostr DMs - but this doesn't make it a "nostr app" any more than a website that emails you hot deals on herbal supplements is an "email app". These apps are purely parasitic on the nostr ecosystem.
In the long-term, that's not necessarily a bad thing. Email's ubiquity is self-reinforcing. But in the short term, this kind of "nostr app" can actually do damage to nostr's reputation by over-promising and under-delivering.
It complements nostr
Next up, we have apps that get some benefit out of nostr as above, but give back by providing a unique value proposition to nostr users as nostr users. This is a bit of a fine distinction, but for me this category is for apps which focus on solving problems that nostr isn't good at solving, leaving the nostr integration in a secondary or supporting role.
One example of this kind of app was Mutiny (RIP), which not only allowed users to sign in with nostr, but also pulled those users' social graphs so that users could send money to people they knew and trusted. Mutiny was doing a great job of leveraging nostr, as well as providing value to users with nostr identities - but it was still primarily a bitcoin wallet, not a "nostr app" in the purest sense.
Other examples are things like Nostr Nests and Zap.stream, whose core value proposition is streaming video or audio content. Both make great use of nostr identities, data formats, and relays, but they're primarily streaming apps. A good litmus test for things like this is: if you got rid of nostr, would it be the same product (even if inferior in certain ways)?
A similar category is infrastructure providers that benefit nostr by their existence (and may in fact be targeted explicitly at nostr users), but do things in a centralized, old-web way; for example: media hosts, DNS registrars, hosting providers, and CDNs.
To be clear here, I'm not casting aspersions (I don't even know what those are, or where to buy them). All the apps mentioned above use nostr to great effect, and are a real benefit to nostr users. But they are not True Scotsmen.
It embodies nostr
Ok, here we go. This is the crème de la crème, the top du top, the meilleur du meilleur, the bee's knees. The purest, holiest, most chaste category of nostr app out there. The apps which are, indeed, nostr indigitate.
This category of nostr app (see, no quotes this time) can be defined by the converse of the previous category. If nostr was removed from this type of application, would it be impossible to create the same product?
To tease this apart a bit, apps that leverage the technical aspects of nostr are dependent on nostr the protocol, while apps that benefit nostr exclusively via network effect are integrated into nostr the network. An app that does both things is working in symbiosis with nostr as a whole.
An app that embraces both nostr's protocol and its network becomes an organic extension of every other nostr app out there, multiplying both its competitive moat and its contribution to the ecosystem:
- In contrast to apps that only borrow from nostr on the technical level but continue to operate in their own silos, an application integrated into the nostr network comes pre-packaged with existing users, and is able to provide more value to those users because of other nostr products. On nostr, it's a good thing to advertise your competitors.
- In contrast to apps that only market themselves to nostr users without building out a deep integration on the protocol level, a deeply integrated app becomes an asset to every other nostr app by becoming an organic extension of them through interoperability. This results in increased traffic to the app as other developers and users refer people to it instead of solving their problem on their own. This is the "micro-apps" utopia we've all been waiting for.
Credible exit doesn't matter if there aren't alternative services. Interoperability is pointless if other applications don't offer something your app doesn't. Marketing to nostr users doesn't matter if you don't augment their agency as nostr users.
If I had to choose a single NIP that represents the mindset behind this kind of app, it would be NIP 89 A.K.A. "Recommended Application Handlers", which states:
Nostr's discoverability and transparent event interaction is one of its most interesting/novel mechanics. This NIP provides a simple way for clients to discover applications that handle events of a specific kind to ensure smooth cross-client and cross-kind interactions.
These handlers are the glue that holds nostr apps together. A single event, signed by the developer of an application (or by the application's own account) tells anyone who wants to know 1. what event kinds the app supports, 2. how to link to the app (if it's a client), and (if the pubkey also publishes a kind 10002), 3. which relays the app prefers.
As a sidenote, NIP 89 is currently focused more on clients, leaving DVMs, relays, signers, etc somewhat out in the cold. Updating 89 to include tailored listings for each kind of supporting app would be a huge improvement to the protocol. This, plus a good front end for navigating these listings (sorry nostrapp.link, close but no cigar) would obviate the evil centralized websites that curate apps based on arbitrary criteria.
Examples of this kind of app obviously include many kind 1 clients, as well as clients that attempt to bring the benefits of the nostr protocol and network to new use cases - whether long form content, video, image posts, music, emojis, recipes, project management, or any other "content type".
To drill down into one example, let's think for a moment about forms. What's so great about a forms app that is built on nostr? Well,
- There is a spec for forms and responses, which means that...
- Multiple clients can implement the same data format, allowing for credible exit and user choice, even of...
- Other products not focused on forms, which can still view, respond to, or embed forms, and which can send their users via NIP 89 to a client that does...
- Cryptographically sign forms and responses, which means they are self-authenticating and can be sent to...
- Multiple relays, which reduces the amount of trust necessary to be confident results haven't been deliberately "lost".
Show me a forms product that does all of those things, and isn't built on nostr. You can't, because it doesn't exist. Meanwhile, there are plenty of image hosts with APIs, streaming services, and bitcoin wallets which have basically the same levels of censorship resistance, interoperability, and network effect as if they weren't built on nostr.
It supports nostr
Notice I haven't said anything about whether relays, signers, blossom servers, software libraries, DVMs, and the accumulated addenda of the nostr ecosystem are nostr apps. Well, they are (usually).
This is the category of nostr app that gets none of the credit for doing all of the work. There's no question that they qualify as beautiful nostrcorns, because their value propositions are entirely meaningless outside of the context of nostr. Who needs a signer if you don't have a cryptographic identity you need to protect? DVMs are literally impossible to use without relays. How are you going to find the blossom server that will serve a given hash if you don't know which servers the publishing user has selected to store their content?
In addition to being entirely contextualized by nostr architecture, this type of nostr app is valuable because it does things "the nostr way". By that I mean that they don't simply try to replicate existing internet functionality into a nostr context; instead, they create entirely new ways of putting the basic building blocks of the internet back together.
A great example of this is how Nostr Connect, Nostr Wallet Connect, and DVMs all use relays as brokers, which allows service providers to avoid having to accept incoming network connections. This opens up really interesting possibilities all on its own.
So while I might hesitate to call many of these things "apps", they are certainly "nostr".
Appendix: it smells like a NINO
So, let's say you've created an app, but when you show it to people they politely smile, nod, and call it a NINO (Nostr In Name Only). What's a hacker to do? Well, here's your handy-dandy guide on how to wash that NINO stench off and Become a Nostr.
You app might be a NINO if:
- There's no NIP for your data format (or you're abusing NIP 78, 32, etc by inventing a sub-protocol inside an existing event kind)
- There's a NIP, but no one knows about it because it's in a text file on your hard drive (or buried in your project's repository)
- Your NIP imposes an incompatible/centralized/legacy web paradigm onto nostr
- Your NIP relies on trusted third (or first) parties
- There's only one implementation of your NIP (yours)
- Your core value proposition doesn't depend on relays, events, or nostr identities
- One or more relay urls are hard-coded into the source code
- Your app depends on a specific relay implementation to work (ahem, relay29)
- You don't validate event signatures
- You don't publish events to relays you don't control
- You don't read events from relays you don't control
- You use legacy web services to solve problems, rather than nostr-native solutions
- You use nostr-native solutions, but you've hardcoded their pubkeys or URLs into your app
- You don't use NIP 89 to discover clients and services
- You haven't published a NIP 89 listing for your app
- You don't leverage your users' web of trust for filtering out spam
- You don't respect your users' mute lists
- You try to "own" your users' data
Now let me just re-iterate - it's ok to be a NINO. We need NINOs, because nostr can't (and shouldn't) tackle every problem. You just need to decide whether your app, as a NINO, is actually contributing to the nostr ecosystem, or whether you're just using buzzwords to whitewash a legacy web software product.
If you're in the former camp, great! If you're in the latter, what are you waiting for? Only you can fix your NINO problem. And there are lots of ways to do this, depending on your own unique situation:
- Drop nostr support if it's not doing anyone any good. If you want to build a normal company and make some money, that's perfectly fine.
- Build out your nostr integration - start taking advantage of webs of trust, self-authenticating data, event handlers, etc.
- Work around the problem. Think you need a special relay feature for your app to work? Guess again. Consider encryption, AUTH, DVMs, or better data formats.
- Think your idea is a good one? Talk to other devs or open a PR to the nips repo. No one can adopt your NIP if they don't know about it.
- Keep going. It can sometimes be hard to distinguish a research project from a NINO. New ideas have to be built out before they can be fully appreciated.
- Listen to advice. Nostr developers are friendly and happy to help. If you're not sure why you're getting traction, ask!
I sincerely hope this article is useful for all of you out there in NINO land. Maybe this made you feel better about not passing the totally optional nostr app purity test. Or maybe it gave you some actionable next steps towards making a great NINON (Nostr In Not Only Name) app. In either case, GM and PV.

2025-01-30 12:23:04Tech stocks have taken a hit globally after China's DeepSeek launched a competitive AI chatbot at a much lower cost than US counterparts. This has stirred market fears of a $1.2 trillion loss across tech companies when trading opens in New York.
DeepSeek’s chatbot quickly topped download charts and surprised experts with its capabilities, developed for only $5.6 million.
The Nasdaq dropped over 3% in premarket trading, with major firms like Nvidia falling more than 10%. SoftBank also saw losses shortly after investing in a significant US AI venture.
Venture capitalist Marc Andreessen called it “AI’s Sputnik moment,” highlighting its potential impact on the industry.

2025-05-06 09:17:39I’m going to talk about Ethereum, hear me out.
Ethereum is a Turing complete consensus blockchain tokenised by its own currency Ether.
This idea by Vitalik Buterin was incredibly compelling and still is today, even though few real world use cases have emerged.
For example, as a company, I could pay a carbon tax in Ether, locked into a smart contract. If the temperate rises by more than “n” degrees year on year based on a known agreed external (blind) oracle, say a weather station located near my factory.
Fantastic, we now have an automatic climate tax.
In reality, few realistic applications exist, however the idea is very compelling and many flocked to Ethereum as a promise of the future. This inflated its utility token “Ether” into stratospherically high prices.
This, in turn, attracted speculative investors and traders only looking at the price signal of the token and no longer considering the utility. This created a bubble which has gradually deflated over time.
This is why we are seeing Bitcoin, which only attempts to be money, succeed relative to Ethereum.
As Ethereum fails, and Bitcoin development strides on, an opportunity arises to try to do what Ethereum and all the other related altcoins have so far failed to do. Computational utility. And to do this on Bitcoin, the most successful “Crypto”.
The first unintended hijack of Ethereums utility are the JPEGs we are seeing on our blockchain.
This latest drive to make Bitcoin Turing complete is potentially the final destination for developers keen to explore the potential of Bitcoins eco-system.
Perhaps Bitcoin is going to absorb all the altcoins. Perhaps that is the goal of Bitcoins developers.
I don’t comment whether this is good or bad, I’m just exploring whether this may be the agenda.

A once-functional object, now eroded by time and human intervention, stripped of its original purpose. Layers of presence accumulate—marks, alterations, traces of intent—until the very essence is obscured. Restoration is paradoxical: to reclaim, one must erase. Yet erasure is an impossibility, for to remove these imprints is to deny the existence of those who shaped them.
The work stands as a meditation on entropy, memory, and the irreversible dialogue between creation and decay.

2025-05-06 11:49:22A few weeks ago, I ran into an old friend at a coffee shop. We hadn’t spoken in years, and within five minutes, she said something I’ve heard countless times:
“I just feel like I’m so behind.”
Behind who? Behind what?
There’s this idea—quiet, nagging, oddly universal—that we’re all somehow in a race we didn’t sign up for. That we’re supposed to have hit certain milestones by certain ages. That if we’re not married, promoted, rich, settled, happy (and photogenic) by 30 or 40 or pick your poison, then we’ve failed some invisible test.
Where did this come from?
Some of it’s cultural, obviously. Social media compresses timelines. You’re 27, doom-scrolling, and suddenly someone from high school just IPO’d their startup and got engaged in Rome. Another just bought a house with a kitchen island the size of a small country. You wonder if you missed a memo.
But beneath that, there’s something deeper. A belief that life is linear. That it should look like a staircase: school, job, marriage, house, kids, success. But real life? It’s a squiggle. A mess. A beautiful disaster.
Here’s the truth: You’re not behind. There’s no schedule. There’s only your path, and the courage it takes to stay on it—even when it looks wildly different from everyone else’s.
I say this as someone who has taken the “scenic route.” I changed careers in my 30s. I moved cities on a hunch. I dropped things that looked great on paper because they felt wrong in my gut. I’ve had seasons of momentum and seasons of stuckness. Both were necessary.
“Catching up” assumes there’s a fixed destination. But what if there isn’t? What if the point isn’t arrival, but presence? Progress that feels real, not performative?
If you need a permission slip to stop comparing, let this be it.
You’re not late. You’re not early.
You’re right on time. -

2025-05-06 11:49:20There’s something sacred about morning air — the way it carries just enough chill to remind you you’re alive, without pushing you back inside. I’ve been starting my days on the balcony lately. Not because it’s glamorous (it isn’t), or because I have a routine (I don’t), but because it’s the only space in my apartment that feels both open and still.
This morning I made coffee with too much cinnamon and curled up with a blanket that’s seen better days. I watched the city slowly wake up — one barking dog, two joggers, and the clatter of a recycling truck below. It’s odd how these tiny patterns become a kind of comfort.
I used to think that slowing down meant falling behind. But here, perched on the third floor with my feet on cold concrete and the sky just starting to blush, I feel like I’m exactly where I’m supposed to be.
If you’re reading this, maybe you needed that reminder too.

1️⃣ Be where the bear roams. Stay in its territory, where it hunts for food. No point setting a trap in your backyard if the bear’s chilling in the forest.
2️⃣ Set a well-hidden trap. Bury it, disguise it, and place the bait right in the center. Bears are omnivores—just like secret police KGB agents. And what’s the tastiest bait for them? Money.
3️⃣ Wait for the bear to take the bait. When it reaches in, the trap will snap shut around its paw. It’ll be alive, but stuck. No escape.
Now, what you do with a trapped bear is another question... 😏

2025-01-25 22:16:54President Trump plans to withdraw 20,000 U.S. troops from Europe and expects European allies to contribute financially to the remaining military presence. Reported by ANSA, Trump aims to deliver this message to European leaders since taking office. A European diplomat noted, “the costs cannot be borne solely by American taxpayers.”
The Pentagon hasn't commented yet. Trump has previously sought lower troop levels in Europe and had ordered cuts during his first term. The U.S. currently maintains around 65,000 troops in Europe, with total forces reaching 100,000 since the Ukraine invasion. Trump's new approach may shift military focus to the Pacific amid growing concerns about China.

2025-05-06 10:35:01All across the Lightning Network we can detect quite a lot of nodes, specially new nodes but also old nodes, that show a concerning lack of good node operation which impedes proper routing. I’ve seen nodes with a variable capacity whose channels are stagnant and non performant, which raises a question: what is the point on maintaining a public node if you are not able to route and dynamically assign resources as needed? Certainly it is a useless node, and channels of those nodes with other nodes better maintained are also useless, not because the fault of the good ones, but because the fault of the bad ones, which makes the whole network not as performant and great as it should be.
For the shake of improving the Lightning Network, I have created this guide, so every node out there can become useful, and, also, will greatly improve gains in routing for itself. Do not expect to become rich or even live out of routing fees, that is impossible unless you have a node with 100 or more BTC in 2025, but at least, a node should be able to cover its own maintenance costs; its the idea. Problem is that, currently, most nodes run on a loss, and that is highly related with the fee policy and the choice of nodes that they connect to. Let’s put an end to this. Here you will learn how to, at least, earn enough to cover electricity of your node, and with luck, a bit more.
Current earnings cover electricity and the payment of my node:
3K sats per day might not seem much for a 5 BTC capacity (2.5 BTC real outbound) node, but the screenshot was taken in a bad day, when the mempool was empty. I took the screenshot of a bad day on purpose, to prove my point. Some other days, specially when Bitcoin is going bullish and it is used a lot, I have seen 20K per day. A quick calculation brings around 1M sats per year at a minimum, more than enough to pay electricity, the machine, and even a bit more for beers and fun! Real gains across the year could be closer to around 5M in my case, which is not bad. And what is incredible, I maintain general low fees for most of the cases, except when I have no liquidity in the channel which must be high, as you will understand later in this article. So if you double or triple my recommended fees I would expect quite a lot more earnings. So expect gains of around 2% of the total capacity (4% for the amount you put in) per year minimum, and any extra beyond that by fine-tuning my recommendations I'm sure it will be very welcomed by you!
Step 1: put the node in a good machine
Please, don’t use an old computer or laptop, unless you change the SSD for a new one. Bitcoin and lightning uses the SSD heavily, which means it will fry it sooner or later. That is so that I recommend changing the SSD every 2 years even it it still feels good. If your SSD dies during operation, expect big loses. I’ve seen this so many times, and it also happened to me, that I am very serious about recommending it. Also, please use only Linux with ext4 file format, other formats, including ZFS, I’ve seen failing badly. If your filesystem fails, the sqlite db that LND or CLN uses will fail and you will force close many if not most channels, with big fees for onchain closings, which will totally ruin all your gains. You have been warned!
Also, please take your time to configure a clearnet (ipv4) address. Do not rely only on Tor, because Tor is slow and unreliable, specially when updating channel states on the gossip, which you will be doing a lot. Of course, configure Tor also, but as secondary, because too many nodes are Tor only, which is unfortunate.
Step 2: connect to good nodes
As a public node operator, your duty is to connect to as many nodes as possible, but first, to good reputable nodes. Your first 10 channels should be with big nodes and service providers, like exchanges, wallets, but also to very well positioned big nodes. Take your time to select these 10 first nodes and connect to the ones you think will improve your position in the network. Don’t choose the first 10 biggest, take your time to study the fees. Select nodes that use a wide range of fees, from 0 to 1000ppm. Don’t discard a node because you see some channels with high fees, it could only mean that they have no liquidity right now in that channel. But if all its channels have high fees, or at least all small channels have high fees, then discard it.
Then, when you have your first 10 big nodes connected, go ahead and go to https://lightningnetwork.plus/ to choose less popular ones. You need them, because you seek to fill the voids between smaller nodes, it is what most of your revenue will come from. Always try to do swaps, use the liquidity pool later when you have enough total inbound liquidity. Remember that total capacity is not total outbound. Total capacity is total outbound + total inbound. So you can start with 0.25BTC of your own, but total capacity could be much higher if other peers have open channels to you.
A proper public node should have a minimum of 50 channels at its peak. It doesn’t matter much the size of the channels, but the quantity and the quality. A node with 50x500k sized channels will usually perform 10x better than a node with 5x5M sized channels, even if they have the same total capacity. This is because more opportunities to route will be found if you have more channels, which means you are much better positioned.
Anyway, the minimum recommended is 1M per channel because most HTCLs are 100k to 500k and less than 1M will wipe out all your liquidity in the channels in one or two routings. This could change in the future because of the Bitcoin price, but in 2025 this is the state of things. But if you don’t have 0.25 BTC to open 50 channels (25 open by you, 25 by others using swaps), just use smaller channels, don't let your available liquidity to crush your excitement, who knows what is the future ahead us! Remember that we are just at the beginning of this technology and there is nothing that impides your channels to be open for the next 20 years when 1BTC=$1M! I would put the ultra minimum at 250k per channel, which means a 12.5M node (6.25M required sats to start with), but even that is too precarious in 2025. But hopefully not in the future! If you have less than that my honest recommendation is to run a private node and open private channels only, and only if you absolutely need a node because you have to provide a service for multiple people and you can't conform to use simpler wallets. Right now, I can think of only one example of requiring an ultra-small node instead of wallets, which is using LNBits to service your small business or family. Be aware, anyway, that a 12.5M node will definitely not cover your node running costs in 2025, it is just an investment and positioning for a future!
In any case, never, ever, put all your BTC in a LN node, at most one third of your bitcoins and only when you are confident.
Also remember you have to be online 24/7. Please, don’t setup a node if you can’t. Remember you are providing a constant service, not an intermittent one. This guide won’t work if you are not committed to this rule.
Step 3: understand the flow
I’ve seen too many node operators that do not understand how payments are routed, and this is a big problem, because this is the base of everything we do with a LN node.
Payments go from one node to another to another to another until it reaches destination. Each node has what is called an outbound fee. This fee controls how much does it cost to route a payment through that node. If the fee is low it is considered attractive and other nodes will prefer to use that route. If the fee is high, it is obvious that nodes will not choose that route unless there is no other way.
But there is a problem here: all channels have a liquidity limit. If a channel has 1M liquidity and a payment of 500k comes through it, then now the channel has 500k liquidity, that is, a ratio of 0.5. If another 400k comes through, now it has 100k liquidity and a ratio of 0.1. If now somebody tries to route a 200k payment through that channel, and error will happen, because it doesn’t have enough liquidity. It is called an HTCL failure, and this are quite normal. Liquidity can come backwards, which means that now that channel becomes the income instead of the outcome, so if 300k comes in, in the example above, now the liquidity ratio is 0.4 (100k already there plus 300k that just came in). So it is easy to understand that liquidity is very volatile: it will come in and out with any successful in or out HTLC.
The problem is: how do you know if a channel has liquidity? For privacy reasons, the liquidity of a channel is never announced, and only the two connected nodes know it. This is logical, to avoid bad actors to figure out which payments have been done by other people. So the only possible solution is to try all connected channels you have until one lets you go through because it has enough liquidity. And it is going to be done, always, in the order of outbound fees, from low to high. So the channel that has the lowest fee with enough liquidity, will catch the prize.
There is a way to signal that you have liquidity or you don’t, and it is based on scarcity: if you don’t have much liquidity, you increase the outbound fee, so other nodes will not find attractive to route through you in that direction. You don't have much liquidity, so why bother to allow routing? But, when you have again outbound liquidity, because other nodes have taken the opposite direction (inbound) using another channel of yours which has liquidity (as outbound), you intelligently lower the fees to signal your new updated increased liquidity in the channel. So, the idea is simple: if you have liquidity in the channel, you put low fees, if you don’t have liquidity, you put high fees. Please read that again until you fully understand it, it is extremely important.
There is another concept introduced by LND which is negative inbound fees: if you put negative inbound fees, for example -100ppm, it means that any payment going from that inbound channel to another of your outbound channels, will have a maximum discount of 100ppm. (Don’t worry, you will never lose because LND forbids to route losing money, so 100ppm is the maximum, but it could be less if the outgoing channel has less than 100ppm fees.) What this does is to encourage the filling of empty channels at the cost of earning less in channels with plenty of liquidity. This is very good, because it will automatically rebalance your extremes: channels with no liquidity will be filled up, channels with plenty of liquidity will be emptied down, creating a balance.
It is obvious that the total ratio, including all your channels, should be around 100%. That means that the total amount summing all channels of inbound and outbound should be approximately the same. Don’t get obsessed with this, 80% or 120% is ok too, but if it is lower or higher than that you should take measures to open or close channels, or even swap out or in using boltz.exchange or LOOP.
Step 4: managing fees
So, in order to make proper routing, you will have to constantly monitor all your channels on a regular basis. Minimum recommended frequency is once a day. You can do this automatically or manually. Some people prefer to do it manually because each channel has its own characteristics and some fees work better than others, which is something you learn with time observing the flow. But some other people, like me, don’t want to spend so much time doing so, and do automatic fee management using charge-lnd or lndg automators. A mixture of both styles is possible by disabling automatic fee management for selected channels.
Every node operator has his/her own preferences, but here are some basic recommendations that you can tweak over time as you acquire experience:
ratio > 0.98: fees 0 (or less than 10) 0.2 < ratio < 0.98: fees proportional max 128, min 16 0.2 > ratio > 0.05: fees 500, inbound -16 ratio < 0.05: fees 1000, inbound -64 ratio = 0: fees more than 1000, inbound -128
So, as you can see, when the channel is full we encourage routing, when the channel is more balanced is when the earnings will occur (from 16 to 128ppm), when the channel is mostly empty we discourage forward routing (500ppm) but encourage backwards routing (inbound -16) and when it is almost empty we clearly totally discourage forward routing (1000ppm) but encourage backwards routing (inbound -64). And when someone just opened a channel with us, all liquidity is theirs so we aggressively encourage inbound routing by putting ultra high outbound fees and ultra inbound discounts. Simple, eh?Step 5: automatic fee management
As stated before, you can automate this using charge-lnd or lndg or Lightning Terminal if you use LND. If you use CLN you are probably limited to create a personalized script, because I don’t know of any similar tool for it, apart from CL-BOSS which is unmaintained and non-customizable.
You will run this configuration a maximum of once per hour, and a minimum of once per day. You should not try to run it more frequent than once per hour because of two reasons: 1. The channel states stored in the gossip take from some minutes to some hours to properly propagate. 2. Some nodes will ban you if you try to update more than once per hour. What I recommend is once every 2 hours for big nodes with more than 50 channels. If you have less than 50 channels, your gossip will be slow to propagate so run it once a day. If you get many “Insufficient Fee” errors is because you are trying to update channel states too frequently. Also, some people report that increasing the variable numgraphsyncpeers in the LND configuration file helps with better propagation, but be aware that this will increase bandwidth usage.
I’ve been using lndg for some time, but I switched to charge-lnd because it is clearly superior and faster and more customizable. Lndg is still great for rebalancing (which I use a lot) and as a general interface, but I have disabled the fee management, which I now do with charge-lnd. If you can’t access charge-lnd then just use lndg with the frequency chosen above, but be aware that the configuration parameters are very limited, as you will soon realize (you are limited to just one strategy which is proportional, and it is very slow as it changes the fee in incremental steps). Yet it is better using lndg than nothing.
Lightning Terminal from Lightning Labs I have not tested. So I can’t say anything about it.
But here is a good starting configuration for charge-lnd that you can customize to your preferences:
``` [default]
'default' is special, it is used if no other policy matches a channel
strategy = static base_fee_msat = 128 fee_ppm = 96 inbound_base_fee_msat = 0 inbound_fee_ppm = 0 min_fee_ppm_delta=20
[mydefaults]
no strategy, so this only sets some defaults
base_fee_msat = 128 min_fee_ppm_delta = 0
[lost-onchain-sync]
The fact that lnd was not synchronized with the chain for more than 5 minutes
was an indicator of a severe problem in the past.
onchain.synced_to_chain = false base_fee_msat = 210_000 fee_ppm = 210_000
[expensive]
match channels where the peer node has set a high (>=8_000 ppm) fee rate
and set the same fee rate on our side (strategy=match_peer)
chan.min_fee_ppm = 8000 strategy = match_peer
[leafnode]
charge non-routing (private=true) peers a bit more for our service
chan.private = true strategy = static fee_ppm = 1000
[encourage-routing]
'autobalance' (lower fees so using outbound is more attractive)
chan.min_ratio = 0.98 inbound_base_fee_msat = 0 inbound_fee_ppm = 0 strategy = static base_fee_msat = 64 fee_ppm = 16
[discourage-routing]
'autobalance' (higher fees so using outbound is less attractive)
chan.max_ratio = 0.2 chan.min_ratio = 0.05 strategy = proportional inbound_base_fee_msat = -64 inbound_fee_ppm = -16 min_fee_ppm = 32 max_fee_ppm = 700 base_fee_msat = 1_000
[all-liquidity-is-theirs] chan.max_ratio = 0.00 inbound_base_fee_msat = -128 inbound_fee_ppm = -128 strategy = static base_fee_msat = 1_000 fee_ppm = 1000
[discourage-routing-extreme] chan.max_ratio = 0.05 inbound_base_fee_msat = -128 inbound_fee_ppm = -32 strategy = proportional min_fee_ppm = 32 max_fee_ppm = 1000 base_fee_msat = 1_000
[proportional]
'proportional' can also be used to auto balance (lower fee rate when low remote balance & higher rate when higher remote balance)
fee_ppm decreases linearly with the channel balance ratio (min_fee_ppm when ratio is 1, max_fee_ppm when ratio is 0)
20% excess:
chan.min_ratio = 0.2 chan.max_ratio = 0.98 strategy = proportional min_fee_ppm = 32
20% excess, so for a max of 128, it’s calculated 128/(1-0.20)=160
max_fee_ppm = 160 inbound_base_fee_msat = 0 inbound_fee_ppm = 0 base_fee_msat = 128 min_fee_ppm_delta=16 ```
So you might run this config in a crontab or with your node distribution script if it is provided. I think Umbrel has this app in their portfolio, so just use it if you have Umbrel and ignore the following. If you run it manually or with a distro that doesn’t have charge-lnd, you can configure a crontab. This is just an example, please ask support for proper configuration on your distro. And if you distro do not include charge-lnd, ask support to include it, at this point it’s quite a necessity. Anyway here is the manual configuration: ``` $ crontab -e
0 */2 * * * echo "=======>"
date
>> /home/nodo/charge-lnd/log && /home/nodo/charge-lnd/env/bin/charge-lnd -c /home/nodo/charge-lnd/my.config >> /home/nodo/charge-lnd/log ```That is supposing charge-lnd executable is installed under /home/nodo/charge-lnd/env/bin/charge-lnd and config is in /home/nodo/charge-lnd/my.config and LND is running without docker. If it is running under docker, you will have to ask support of your distro.
Step 6: help your peers
Remember that your peers are not only your competition, they are also your customers. So it is a strange symbiosis: you compete with them, but they also help you (and you help them).
If your peers are not well informed and have a bad maintained node, you are in a loss, because your channels with them will get stagnant and will not route. If they are well informed and know how to manage a node, then the channels will not be stagnant and they will route through you.
So it is stupid to keep this information as a secret. Every node operator should know it. And the more people know it, the better for everybody.
So, please, if you detect stagnant channels and bad maintained peers connected to you, just lead them to this guide, or guide them yourself. It’s a good idea to bookmark this guide so you have it prepared for the future.
And that’s it!! Happy routing!!

2025-01-21 01:51:46Bitcoin: Um sistema de dinheiro eletrônico direto entre pessoas.
Satoshi Nakamoto
satoshin@gmx.com
www.bitcoin.org
Resumo
O Bitcoin é uma forma de dinheiro digital que permite pagamentos diretos entre pessoas, sem a necessidade de um banco ou instituição financeira. Ele resolve um problema chamado gasto duplo, que ocorre quando alguém tenta gastar o mesmo dinheiro duas vezes. Para evitar isso, o Bitcoin usa uma rede descentralizada onde todos trabalham juntos para verificar e registrar as transações.
As transações são registradas em um livro público chamado blockchain, protegido por uma técnica chamada Prova de Trabalho. Essa técnica cria uma cadeia de registros que não pode ser alterada sem refazer todo o trabalho já feito. Essa cadeia é mantida pelos computadores que participam da rede, e a mais longa é considerada a verdadeira.
Enquanto a maior parte do poder computacional da rede for controlada por participantes honestos, o sistema continuará funcionando de forma segura. A rede é flexível, permitindo que qualquer pessoa entre ou saia a qualquer momento, sempre confiando na cadeia mais longa como prova do que aconteceu.
1. Introdução
Hoje, quase todos os pagamentos feitos pela internet dependem de bancos ou empresas como processadores de pagamento (cartões de crédito, por exemplo) para funcionar. Embora esse sistema seja útil, ele tem problemas importantes porque é baseado em confiança.
Primeiro, essas empresas podem reverter pagamentos, o que é útil em caso de erros, mas cria custos e incertezas. Isso faz com que pequenas transações, como pagar centavos por um serviço, se tornem inviáveis. Além disso, os comerciantes são obrigados a desconfiar dos clientes, pedindo informações extras e aceitando fraudes como algo inevitável.
Esses problemas não existem no dinheiro físico, como o papel-moeda, onde o pagamento é final e direto entre as partes. No entanto, não temos como enviar dinheiro físico pela internet sem depender de um intermediário confiável.
O que precisamos é de um sistema de pagamento eletrônico baseado em provas matemáticas, não em confiança. Esse sistema permitiria que qualquer pessoa enviasse dinheiro diretamente para outra, sem depender de bancos ou processadores de pagamento. Além disso, as transações seriam irreversíveis, protegendo vendedores contra fraudes, mas mantendo a possibilidade de soluções para disputas legítimas.
Neste documento, apresentamos o Bitcoin, que resolve o problema do gasto duplo usando uma rede descentralizada. Essa rede cria um registro público e protegido por cálculos matemáticos, que garante a ordem das transações. Enquanto a maior parte da rede for controlada por pessoas honestas, o sistema será seguro contra ataques.
2. Transações
Para entender como funciona o Bitcoin, é importante saber como as transações são realizadas. Imagine que você quer transferir uma "moeda digital" para outra pessoa. No sistema do Bitcoin, essa "moeda" é representada por uma sequência de registros que mostram quem é o atual dono. Para transferi-la, você adiciona um novo registro comprovando que agora ela pertence ao próximo dono. Esse registro é protegido por um tipo especial de assinatura digital.
O que é uma assinatura digital?
Uma assinatura digital é como uma senha secreta, mas muito mais segura. No Bitcoin, cada usuário tem duas chaves: uma "chave privada", que é secreta e serve para criar a assinatura, e uma "chave pública", que pode ser compartilhada com todos e é usada para verificar se a assinatura é válida. Quando você transfere uma moeda, usa sua chave privada para assinar a transação, provando que você é o dono. A próxima pessoa pode usar sua chave pública para confirmar isso.
Como funciona na prática?
Cada "moeda" no Bitcoin é, na verdade, uma cadeia de assinaturas digitais. Vamos imaginar o seguinte cenário:
- A moeda está com o Dono 0 (você). Para transferi-la ao Dono 1, você assina digitalmente a transação com sua chave privada. Essa assinatura inclui o código da transação anterior (chamado de "hash") e a chave pública do Dono 1.
- Quando o Dono 1 quiser transferir a moeda ao Dono 2, ele assinará a transação seguinte com sua própria chave privada, incluindo também o hash da transação anterior e a chave pública do Dono 2.
- Esse processo continua, formando uma "cadeia" de transações. Qualquer pessoa pode verificar essa cadeia para confirmar quem é o atual dono da moeda.
Resolvendo o problema do gasto duplo
Um grande desafio com moedas digitais é o "gasto duplo", que é quando uma mesma moeda é usada em mais de uma transação. Para evitar isso, muitos sistemas antigos dependiam de uma entidade central confiável, como uma casa da moeda, que verificava todas as transações. No entanto, isso criava um ponto único de falha e centralizava o controle do dinheiro.
O Bitcoin resolve esse problema de forma inovadora: ele usa uma rede descentralizada onde todos os participantes (os "nós") têm acesso a um registro completo de todas as transações. Cada nó verifica se as transações são válidas e se a moeda não foi gasta duas vezes. Quando a maioria dos nós concorda com a validade de uma transação, ela é registrada permanentemente na blockchain.
Por que isso é importante?
Essa solução elimina a necessidade de confiar em uma única entidade para gerenciar o dinheiro, permitindo que qualquer pessoa no mundo use o Bitcoin sem precisar de permissão de terceiros. Além disso, ela garante que o sistema seja seguro e resistente a fraudes.
3. Servidor Timestamp
Para assegurar que as transações sejam realizadas de forma segura e transparente, o sistema Bitcoin utiliza algo chamado de "servidor de registro de tempo" (timestamp). Esse servidor funciona como um registro público que organiza as transações em uma ordem específica.
Ele faz isso agrupando várias transações em blocos e criando um código único chamado "hash". Esse hash é como uma impressão digital que representa todo o conteúdo do bloco. O hash de cada bloco é amplamente divulgado, como se fosse publicado em um jornal ou em um fórum público.
Esse processo garante que cada bloco de transações tenha um registro de quando foi criado e que ele existia naquele momento. Além disso, cada novo bloco criado contém o hash do bloco anterior, formando uma cadeia contínua de blocos conectados — conhecida como blockchain.
Com isso, se alguém tentar alterar qualquer informação em um bloco anterior, o hash desse bloco mudará e não corresponderá ao hash armazenado no bloco seguinte. Essa característica torna a cadeia muito segura, pois qualquer tentativa de fraude seria imediatamente detectada.
O sistema de timestamps é essencial para provar a ordem cronológica das transações e garantir que cada uma delas seja única e autêntica. Dessa forma, ele reforça a segurança e a confiança na rede Bitcoin.
4. Prova-de-Trabalho
Para implementar o registro de tempo distribuído no sistema Bitcoin, utilizamos um mecanismo chamado prova-de-trabalho. Esse sistema é semelhante ao Hashcash, desenvolvido por Adam Back, e baseia-se na criação de um código único, o "hash", por meio de um processo computacionalmente exigente.
A prova-de-trabalho envolve encontrar um valor especial que, quando processado junto com as informações do bloco, gere um hash que comece com uma quantidade específica de zeros. Esse valor especial é chamado de "nonce". Encontrar o nonce correto exige um esforço significativo do computador, porque envolve tentativas repetidas até que a condição seja satisfeita.
Esse processo é importante porque torna extremamente difícil alterar qualquer informação registrada em um bloco. Se alguém tentar mudar algo em um bloco, seria necessário refazer o trabalho de computação não apenas para aquele bloco, mas também para todos os blocos que vêm depois dele. Isso garante a segurança e a imutabilidade da blockchain.
A prova-de-trabalho também resolve o problema de decidir qual cadeia de blocos é a válida quando há múltiplas cadeias competindo. A decisão é feita pela cadeia mais longa, pois ela representa o maior esforço computacional já realizado. Isso impede que qualquer indivíduo ou grupo controle a rede, desde que a maioria do poder de processamento seja mantida por participantes honestos.
Para garantir que o sistema permaneça eficiente e equilibrado, a dificuldade da prova-de-trabalho é ajustada automaticamente ao longo do tempo. Se novos blocos estiverem sendo gerados rapidamente, a dificuldade aumenta; se estiverem sendo gerados muito lentamente, a dificuldade diminui. Esse ajuste assegura que novos blocos sejam criados aproximadamente a cada 10 minutos, mantendo o sistema estável e funcional.
5. Rede
A rede Bitcoin é o coração do sistema e funciona de maneira distribuída, conectando vários participantes (ou nós) para garantir o registro e a validação das transações. Os passos para operar essa rede são:
-
Transmissão de Transações: Quando alguém realiza uma nova transação, ela é enviada para todos os nós da rede. Isso é feito para garantir que todos estejam cientes da operação e possam validá-la.
-
Coleta de Transações em Blocos: Cada nó agrupa as novas transações recebidas em um "bloco". Este bloco será preparado para ser adicionado à cadeia de blocos (a blockchain).
-
Prova-de-Trabalho: Os nós competem para resolver a prova-de-trabalho do bloco, utilizando poder computacional para encontrar um hash válido. Esse processo é como resolver um quebra-cabeça matemático difícil.
-
Envio do Bloco Resolvido: Quando um nó encontra a solução para o bloco (a prova-de-trabalho), ele compartilha esse bloco com todos os outros nós na rede.
-
Validação do Bloco: Cada nó verifica o bloco recebido para garantir que todas as transações nele contidas sejam válidas e que nenhuma moeda tenha sido gasta duas vezes. Apenas blocos válidos são aceitos.
-
Construção do Próximo Bloco: Os nós que aceitaram o bloco começam a trabalhar na criação do próximo bloco, utilizando o hash do bloco aceito como base (hash anterior). Isso mantém a continuidade da cadeia.
Resolução de Conflitos e Escolha da Cadeia Mais Longa
Os nós sempre priorizam a cadeia mais longa, pois ela representa o maior esforço computacional já realizado, garantindo maior segurança. Se dois blocos diferentes forem compartilhados simultaneamente, os nós trabalharão no primeiro bloco recebido, mas guardarão o outro como uma alternativa. Caso o segundo bloco eventualmente forme uma cadeia mais longa (ou seja, tenha mais blocos subsequentes), os nós mudarão para essa nova cadeia.
Tolerância a Falhas
A rede é robusta e pode lidar com mensagens que não chegam a todos os nós. Uma transação não precisa alcançar todos os nós de imediato; basta que chegue a um número suficiente deles para ser incluída em um bloco. Da mesma forma, se um nó não receber um bloco em tempo hábil, ele pode solicitá-lo ao perceber que está faltando quando o próximo bloco é recebido.
Esse mecanismo descentralizado permite que a rede Bitcoin funcione de maneira segura, confiável e resiliente, sem depender de uma autoridade central.
6. Incentivo
O incentivo é um dos pilares fundamentais que sustenta o funcionamento da rede Bitcoin, garantindo que os participantes (nós) continuem operando de forma honesta e contribuindo com recursos computacionais. Ele é estruturado em duas partes principais: a recompensa por mineração e as taxas de transação.
Recompensa por Mineração
Por convenção, o primeiro registro em cada bloco é uma transação especial que cria novas moedas e as atribui ao criador do bloco. Essa recompensa incentiva os mineradores a dedicarem poder computacional para apoiar a rede. Como não há uma autoridade central para emitir moedas, essa é a maneira pela qual novas moedas entram em circulação. Esse processo pode ser comparado ao trabalho de garimpeiros, que utilizam recursos para colocar mais ouro em circulação. No caso do Bitcoin, o "recurso" consiste no tempo de CPU e na energia elétrica consumida para resolver a prova-de-trabalho.
Taxas de Transação
Além da recompensa por mineração, os mineradores também podem ser incentivados pelas taxas de transação. Se uma transação utiliza menos valor de saída do que o valor de entrada, a diferença é tratada como uma taxa, que é adicionada à recompensa do bloco contendo essa transação. Com o passar do tempo e à medida que o número de moedas em circulação atinge o limite predeterminado, essas taxas de transação se tornam a principal fonte de incentivo, substituindo gradualmente a emissão de novas moedas. Isso permite que o sistema opere sem inflação, uma vez que o número total de moedas permanece fixo.
Incentivo à Honestidade
O design do incentivo também busca garantir que os participantes da rede mantenham um comportamento honesto. Para um atacante que consiga reunir mais poder computacional do que o restante da rede, ele enfrentaria duas escolhas:
- Usar esse poder para fraudar o sistema, como reverter transações e roubar pagamentos.
- Seguir as regras do sistema, criando novos blocos e recebendo recompensas legítimas.
A lógica econômica favorece a segunda opção, pois um comportamento desonesto prejudicaria a confiança no sistema, diminuindo o valor de todas as moedas, incluindo aquelas que o próprio atacante possui. Jogar dentro das regras não apenas maximiza o retorno financeiro, mas também preserva a validade e a integridade do sistema.
Esse mecanismo garante que os incentivos econômicos estejam alinhados com o objetivo de manter a rede segura, descentralizada e funcional ao longo do tempo.
7. Recuperação do Espaço em Disco
Depois que uma moeda passa a estar protegida por muitos blocos na cadeia, as informações sobre as transações antigas que a geraram podem ser descartadas para economizar espaço em disco. Para que isso seja possível sem comprometer a segurança, as transações são organizadas em uma estrutura chamada "árvore de Merkle". Essa árvore funciona como um resumo das transações: em vez de armazenar todas elas, guarda apenas um "hash raiz", que é como uma assinatura compacta que representa todo o grupo de transações.
Os blocos antigos podem, então, ser simplificados, removendo as partes desnecessárias dessa árvore. Apenas a raiz do hash precisa ser mantida no cabeçalho do bloco, garantindo que a integridade dos dados seja preservada, mesmo que detalhes específicos sejam descartados.
Para exemplificar: imagine que você tenha vários recibos de compra. Em vez de guardar todos os recibos, você cria um documento e lista apenas o valor total de cada um. Mesmo que os recibos originais sejam descartados, ainda é possível verificar a soma com base nos valores armazenados.
Além disso, o espaço ocupado pelos blocos em si é muito pequeno. Cada bloco sem transações ocupa apenas cerca de 80 bytes. Isso significa que, mesmo com blocos sendo gerados a cada 10 minutos, o crescimento anual em espaço necessário é insignificante: apenas 4,2 MB por ano. Com a capacidade de armazenamento dos computadores crescendo a cada ano, esse espaço continuará sendo trivial, garantindo que a rede possa operar de forma eficiente sem problemas de armazenamento, mesmo a longo prazo.
8. Verificação de Pagamento Simplificada
É possível confirmar pagamentos sem a necessidade de operar um nó completo da rede. Para isso, o usuário precisa apenas de uma cópia dos cabeçalhos dos blocos da cadeia mais longa (ou seja, a cadeia com maior esforço de trabalho acumulado). Ele pode verificar a validade de uma transação ao consultar os nós da rede até obter a confirmação de que tem a cadeia mais longa. Para isso, utiliza-se o ramo Merkle, que conecta a transação ao bloco em que ela foi registrada.
Entretanto, o método simplificado possui limitações: ele não pode confirmar uma transação isoladamente, mas sim assegurar que ela ocupa um lugar específico na cadeia mais longa. Dessa forma, se um nó da rede aprova a transação, os blocos subsequentes reforçam essa aceitação.
A verificação simplificada é confiável enquanto a maioria dos nós da rede for honesta. Contudo, ela se torna vulnerável caso a rede seja dominada por um invasor. Nesse cenário, um atacante poderia fabricar transações fraudulentas que enganariam o usuário temporariamente até que o invasor obtivesse controle completo da rede.
Uma estratégia para mitigar esse risco é configurar alertas nos softwares de nós completos. Esses alertas identificam blocos inválidos, sugerindo ao usuário baixar o bloco completo para confirmar qualquer inconsistência. Para maior segurança, empresas que realizam pagamentos frequentes podem preferir operar seus próprios nós, reduzindo riscos e permitindo uma verificação mais direta e confiável.
9. Combinando e Dividindo Valor
No sistema Bitcoin, cada unidade de valor é tratada como uma "moeda" individual, mas gerenciar cada centavo como uma transação separada seria impraticável. Para resolver isso, o Bitcoin permite que valores sejam combinados ou divididos em transações, facilitando pagamentos de qualquer valor.
Entradas e Saídas
Cada transação no Bitcoin é composta por:
- Entradas: Representam os valores recebidos em transações anteriores.
- Saídas: Correspondem aos valores enviados, divididos entre os destinatários e, eventualmente, o troco para o remetente.
Normalmente, uma transação contém:
- Uma única entrada com valor suficiente para cobrir o pagamento.
- Ou várias entradas combinadas para atingir o valor necessário.
O valor total das saídas nunca excede o das entradas, e a diferença (se houver) pode ser retornada ao remetente como troco.
Exemplo Prático
Imagine que você tem duas entradas:
- 0,03 BTC
- 0,07 BTC
Se deseja enviar 0,08 BTC para alguém, a transação terá:
- Entrada: As duas entradas combinadas (0,03 + 0,07 BTC = 0,10 BTC).
- Saídas: Uma para o destinatário (0,08 BTC) e outra como troco para você (0,02 BTC).
Essa flexibilidade permite que o sistema funcione sem precisar manipular cada unidade mínima individualmente.
Difusão e Simplificação
A difusão de transações, onde uma depende de várias anteriores e assim por diante, não representa um problema. Não é necessário armazenar ou verificar o histórico completo de uma transação para utilizá-la, já que o registro na blockchain garante sua integridade.
10. Privacidade
O modelo bancário tradicional oferece um certo nível de privacidade, limitando o acesso às informações financeiras apenas às partes envolvidas e a um terceiro confiável (como bancos ou instituições financeiras). No entanto, o Bitcoin opera de forma diferente, pois todas as transações são publicamente registradas na blockchain. Apesar disso, a privacidade pode ser mantida utilizando chaves públicas anônimas, que desvinculam diretamente as transações das identidades das partes envolvidas.
Fluxo de Informação
- No modelo tradicional, as transações passam por um terceiro confiável que conhece tanto o remetente quanto o destinatário.
- No Bitcoin, as transações são anunciadas publicamente, mas sem revelar diretamente as identidades das partes. Isso é comparável a dados divulgados por bolsas de valores, onde informações como o tempo e o tamanho das negociações (a "fita") são públicas, mas as identidades das partes não.
Protegendo a Privacidade
Para aumentar a privacidade no Bitcoin, são adotadas as seguintes práticas:
- Chaves Públicas Anônimas: Cada transação utiliza um par de chaves diferentes, dificultando a associação com um proprietário único.
- Prevenção de Ligação: Ao usar chaves novas para cada transação, reduz-se a possibilidade de links evidentes entre múltiplas transações realizadas pelo mesmo usuário.
Riscos de Ligação
Embora a privacidade seja fortalecida, alguns riscos permanecem:
- Transações multi-entrada podem revelar que todas as entradas pertencem ao mesmo proprietário, caso sejam necessárias para somar o valor total.
- O proprietário da chave pode ser identificado indiretamente por transações anteriores que estejam conectadas.
11. Cálculos
Imagine que temos um sistema onde as pessoas (ou computadores) competem para adicionar informações novas (blocos) a um grande registro público (a cadeia de blocos ou blockchain). Este registro é como um livro contábil compartilhado, onde todos podem verificar o que está escrito.
Agora, vamos pensar em um cenário: um atacante quer enganar o sistema. Ele quer mudar informações já registradas para beneficiar a si mesmo, por exemplo, desfazendo um pagamento que já fez. Para isso, ele precisa criar uma versão alternativa do livro contábil (a cadeia de blocos dele) e convencer todos os outros participantes de que essa versão é a verdadeira.
Mas isso é extremamente difícil.
Como o Ataque Funciona
Quando um novo bloco é adicionado à cadeia, ele depende de cálculos complexos que levam tempo e esforço. Esses cálculos são como um grande quebra-cabeça que precisa ser resolvido.
- Os “bons jogadores” (nós honestos) estão sempre trabalhando juntos para resolver esses quebra-cabeças e adicionar novos blocos à cadeia verdadeira.
- O atacante, por outro lado, precisa resolver quebra-cabeças sozinho, tentando “alcançar” a cadeia honesta para que sua versão alternativa pareça válida.
Se a cadeia honesta já está vários blocos à frente, o atacante começa em desvantagem, e o sistema está projetado para que a dificuldade de alcançá-los aumente rapidamente.
A Corrida Entre Cadeias
Você pode imaginar isso como uma corrida. A cada bloco novo que os jogadores honestos adicionam à cadeia verdadeira, eles se distanciam mais do atacante. Para vencer, o atacante teria que resolver os quebra-cabeças mais rápido que todos os outros jogadores honestos juntos.
Suponha que:
- A rede honesta tem 80% do poder computacional (ou seja, resolve 8 de cada 10 quebra-cabeças).
- O atacante tem 20% do poder computacional (ou seja, resolve 2 de cada 10 quebra-cabeças).
Cada vez que a rede honesta adiciona um bloco, o atacante tem que "correr atrás" e resolver mais quebra-cabeças para alcançar.
Por Que o Ataque Fica Cada Vez Mais Improvável?
Vamos usar uma fórmula simples para mostrar como as chances de sucesso do atacante diminuem conforme ele precisa "alcançar" mais blocos:
P = (q/p)^z
- q é o poder computacional do atacante (20%, ou 0,2).
- p é o poder computacional da rede honesta (80%, ou 0,8).
- z é a diferença de blocos entre a cadeia honesta e a cadeia do atacante.
Se o atacante está 5 blocos atrás (z = 5):
P = (0,2 / 0,8)^5 = (0,25)^5 = 0,00098, (ou, 0,098%)
Isso significa que o atacante tem menos de 0,1% de chance de sucesso — ou seja, é muito improvável.
Se ele estiver 10 blocos atrás (z = 10):
P = (0,2 / 0,8)^10 = (0,25)^10 = 0,000000095, (ou, 0,0000095%).
Neste caso, as chances de sucesso são praticamente nulas.
Um Exemplo Simples
Se você jogar uma moeda, a chance de cair “cara” é de 50%. Mas se precisar de 10 caras seguidas, sua chance já é bem menor. Se precisar de 20 caras seguidas, é quase impossível.
No caso do Bitcoin, o atacante precisa de muito mais do que 20 caras seguidas. Ele precisa resolver quebra-cabeças extremamente difíceis e alcançar os jogadores honestos que estão sempre à frente. Isso faz com que o ataque seja inviável na prática.
Por Que Tudo Isso é Seguro?
- A probabilidade de sucesso do atacante diminui exponencialmente. Isso significa que, quanto mais tempo passa, menor é a chance de ele conseguir enganar o sistema.
- A cadeia verdadeira (honesta) está protegida pela força da rede. Cada novo bloco que os jogadores honestos adicionam à cadeia torna mais difícil para o atacante alcançar.
E Se o Atacante Tentar Continuar?
O atacante poderia continuar tentando indefinidamente, mas ele estaria gastando muito tempo e energia sem conseguir nada. Enquanto isso, os jogadores honestos estão sempre adicionando novos blocos, tornando o trabalho do atacante ainda mais inútil.
Assim, o sistema garante que a cadeia verdadeira seja extremamente segura e que ataques sejam, na prática, impossíveis de ter sucesso.
12. Conclusão
Propusemos um sistema de transações eletrônicas que elimina a necessidade de confiança, baseando-se em assinaturas digitais e em uma rede peer-to-peer que utiliza prova de trabalho. Isso resolve o problema do gasto duplo, criando um histórico público de transações imutável, desde que a maioria do poder computacional permaneça sob controle dos participantes honestos. A rede funciona de forma simples e descentralizada, com nós independentes que não precisam de identificação ou coordenação direta. Eles entram e saem livremente, aceitando a cadeia de prova de trabalho como registro do que ocorreu durante sua ausência. As decisões são tomadas por meio do poder de CPU, validando blocos legítimos, estendendo a cadeia e rejeitando os inválidos. Com este mecanismo de consenso, todas as regras e incentivos necessários para o funcionamento seguro e eficiente do sistema são garantidos.

2025-01-19 17:48:02Einleitung\ \ Schwierige Dinge einfach zu erklären ist der Anspruch von ELI5 (explain me like I'm 5). Das ist in unserer hoch technisierten Welt dringend erforderlich, denn nur mit dem Verständnis der Technologien können wir sie richtig einsetzen und weiter entwickeln.\ Ich starte meine Serie mit Nostr, einem relativ neuen Internet-Protokoll. Was zum Teufel ist ein Internet-Protokoll? Formal beschrieben sind es internationale Standards, die dafür sorgen, dass das Internet seit über 30 Jahren ziemlich gut funktioniert. Es ist die Sprache, in der sich die Rechner miteinander unterhalten und die auch Sie täglich nutzen, vermutlich ohne es bewusst wahrzunehmen. http(s) transportiert ihre Anfrage an einen Server (z.B. Amazon), und html sorgt dafür, dass aus den gelieferten Daten eine schöne Seite auf ihrem Bildschirm entsteht. Eine Mail wird mit smtp an den Mailserver gesendet und mit imap von ihm abgerufen, und da alle den Standard verwenden, funktioniert das mit jeder App auf jedem Betriebssystem und mit jedem Mail-Provider. Und mit einer Mail-Adresse wie roland@pareto.space können sie sogar jederzeit umziehen, egal wohin. Cool, das ist state of the art! Aber warum funktioniert das z.B. bei Chat nicht, gibt es da kein Protokoll? Doch, es heißt IRC (Internet Relay Chat → merken sie sich den Namen), aber es wird so gut wie nicht verwendet. Die Gründe dafür sind nicht technischer Natur, vielmehr wurden mit Apps wie Facebook, Twitter, WhatsApp, Telegram, Instagram, TikTok u.a. bewusst Inkompatibilitäten und Nutzerabhängigkeiten geschaffen um Profite zu maximieren.
Warum Nostr?
Da das Standard-Protokoll nicht genutzt wird, hat jede App ihr eigenes, und wir brauchen eine handvoll Apps um uns mit allen Bekannten auszutauschen. Eine Mobilfunknummer ist Voraussetzung für jedes Konto, damit können die App-Hersteller die Nutzer umfassend tracken und mit dem Verkauf der Informationen bis zu 30 USD je Konto und Monat verdienen. Der Nutzer ist nicht mehr Kunde, er ist das Produkt! Der Werbe-SPAM ist noch das kleinste Problem bei diesem Geschäftsmodell. Server mit Millionen von Nutzerdaten sind ein “honey pot”, dementsprechend oft werden sie gehackt und die Zugangsdaten verkauft. 2024 wurde auch der Twitter-Account vom damaligen Präsidenten Joe Biden gehackt, niemand wusste mehr wer die Nachrichten verfasst hat (vorher auch nicht), d.h. die Authentizität der Inhalte ist bei keinem dieser Anbieter gewährleistet. Im selben Jahr wurde der Telegram-Gründer in Frankreich in Beugehaft genommen, weil er sich geweigert hatte Hintertüren in seine Software einzubauen. Nun kann zum Schutz "unserer Demokratie” praktisch jeder mitlesen, was sie mit wem an Informationen austauschen, z.B. darüber welches Shampoo bestimmte Politiker verwenden.
Und wer tatsächlich glaubt er könne Meinungsfreiheit auf sozialen Medien praktizieren, findet sich schnell in der Situation von Donald Trump wieder (seinerzeit amtierender Präsident), dem sein Twitter-Konto 2021 abgeschaltet wurde (Cancel-Culture). Die Nutzerdaten, also ihr Profil, ihre Kontakte, Dokumente, Bilder, Videos und Audiofiles - gehören ihnen ohnehin nicht mehr sondern sind Eigentum des Plattform-Betreibers; lesen sie sich mal die AGB's durch. Aber nein, keine gute Idee, das sind hunderte Seiten und sie werden permanent geändert. Alle nutzen also Apps, deren Technik sie nicht verstehen, deren Regeln sie nicht kennen, wo sie keine Rechte haben und die ihnen die Resultate ihres Handelns stehlen. Was würde wohl der Fünfjährige sagen, wenn ihm seine ältere Schwester anbieten würde, alle seine Spielzeuge zu “verwalten” und dann auszuhändigen wenn er brav ist? “Du spinnst wohl”, und damit beweist der Knirps mehr Vernunft als die Mehrzahl der Erwachsenen. \ \ Resümee: keine Standards, keine Daten, keine Rechte = keine Zukunft!
\ Wie funktioniert Nostr?
Die Entwickler von Nostr haben erkannt dass sich das Server-Client-Konzept in ein Master-Slave-Konzept verwandelt hatte. Der Master ist ein Synonym für Zentralisierung und wird zum “single point of failure”, der zwangsläufig Systeme dysfunktional macht. In einem verteilten Peer2Peer-System gibt es keine Master mehr sondern nur gleichberechtigte Knoten (Relays), auf denen die Informationen gespeichert werden. Indem man Informationen auf mehreren Relays redundant speichert, ist das System in jeglicher Hinsicht resilienter. Nicht nur die Natur verwendet dieses Prinzip seit Jahrmillionen erfolgreich, auch das Internet wurde so konzipiert (das ARPAnet wurde vom US-Militär für den Einsatz in Kriegsfällen unter massiven Störungen entwickelt). Alle Nostr-Daten liegen auf Relays und der Nutzer kann wählen zwischen öffentlichen (zumeist kostenlosen) und privaten Relays, z.B. für geschlossene Gruppen oder zum Zwecke von Daten-Archivierung. Da Dokumente auf mehreren Relays gespeichert sind, werden statt URL's (Locator) eindeutige Dokumentnamen (URI's = Identifier) verwendet, broken Links sind damit Vergangenheit und Löschungen / Verluste ebenfalls.\ \ Jedes Dokument (Event genannt) wird vom Besitzer signiert, es ist damit authentisch und fälschungssicher und kann nur vom Ersteller gelöscht werden. Dafür wird ein Schlüsselpaar verwendet bestehend aus privatem (nsec) und öffentlichem Schlüssel (npub) wie aus der Mailverschlüsselung (PGP) bekannt. Das repräsentiert eine Nostr-Identität, die um Bild, Namen, Bio und eine lesbare Nostr-Adresse ergänzt werden kann (z.B. roland@pareto.space ), mehr braucht es nicht um alle Ressourcen des Nostr-Ökosystems zu nutzen. Und das besteht inzwischen aus über hundert Apps mit unterschiedlichen Fokussierungen, z.B. für persönliche verschlüsselte Nachrichten (DM → OxChat), Kurznachrichten (Damus, Primal), Blogbeiträge (Pareto), Meetups (Joinstr), Gruppen (Groups), Bilder (Olas), Videos (Amethyst), Audio-Chat (Nostr Nests), Audio-Streams (Tunestr), Video-Streams (Zap.Stream), Marktplätze (Shopstr) u.v.a.m. Die Anmeldung erfolgt mit einem Klick (single sign on) und den Apps stehen ALLE Nutzerdaten zur Verfügung (Profil, Daten, Kontakte, Social Graph → Follower, Bookmarks, Comments, etc.), im Gegensatz zu den fragmentierten Datensilos der Gegenwart.\ \ Resümee: ein offener Standard, alle Daten, alle Rechte = große Zukunft!
\ Warum ist Nostr die Zukunft des Internet?
“Baue Dein Haus nicht auf einem fremden Grundstück” gilt auch im Internet - für alle App-Entwickler, Künstler, Journalisten und Nutzer, denn auch ihre Daten sind werthaltig. Nostr garantiert das Eigentum an den Daten, und überwindet ihre Fragmentierung. Weder die Nutzung noch die kreativen Freiheiten werden durch maßlose Lizenz- und Nutzungsbedingungen eingeschränkt. Aus passiven Nutzern werden durch Interaktion aktive Teilnehmer, Co-Creatoren in einer Sharing-Ökonomie (Value4Value). OpenSource schafft endlich wieder Vertrauen in die Software und ihre Anbieter. Offene Standards ermöglichen den Entwicklern mehr Kooperation und schnellere Entwicklung, für die Anwender garantieren sie Wahlfreiheit. Womit wir letztmalig zu unserem Fünfjährigen zurückkehren. Kinder lieben Lego über alles, am meisten die Maxi-Box “Classic”, weil sie damit ihre Phantasie im Kombinieren voll ausleben können. Erwachsene schenken ihnen dann die viel zu teuren Themenpakete, mit denen man nur eine Lösung nach Anleitung bauen kann. “Was stimmt nur mit meinen Eltern nicht, wann sind die denn falsch abgebogen?" fragt sich der Nachwuchs zu Recht. Das Image lässt sich aber wieder aufpolieren, wenn sie ihren Kindern Nostr zeigen, denn die Vorteile verstehen sogar Fünfjährige.
\ Das neue Internet ist dezentral. Das neue Internet ist selbstbestimmt. Nostr ist das neue Internet.

2025-05-06 10:00:48The dawn of Bitcoin ushered in a transformative mission: empowering individuals and dismantling centralized power structures that erode personal freedoms. As the world’s first decentralized currency, Bitcoin offers an alternative financial system—one that transcends borders, government control, and corporate interests.
But this mission isn’t just about money. It’s about freedom. It’s about self-sovereignty. And most importantly, it’s a rallying cry for vigilance in an ongoing struggle for the liberation of humanity from systemic oppression. Who better to lead this critical mission than those who have already dedicated their lives to serving and protecting freedom: Veterans.
Freedom: A Lifelong Fight Freedom is neither freely given nor guaranteed—it is earned and fiercely preserved. Veterans understand this intimately. They have endured sacrifice, hardship, and battle in their service to protect the liberties we often take for granted. And today, freedom faces threats from a new frontier: financial manipulation, surveillance, and the centralization of power.
Governments across the globe continue to devalue currencies through inflation, tighten financial surveillance by controlling banking systems, and stifle individual autonomy. These issues underscore the need for a sound financial alternative, one that aligns with the ideals veterans have sworn to uphold. The solution? Bitcoin.
Bitcoin represents the antithesis of centralized control. It is censorship-resistant, immune to monetary debasement, and built upon a trustless, transparent system. It is not merely a currency; it is a tool for human liberation.
Vigilance in Bitcoin Adoption While Bitcoin adoption grows, the journey is far from complete. The powerful status quo—central banks, governments, and financial elites—does not take threats to its systems lightly. These entities work tirelessly to misinform, regulate, and marginalize Bitcoin. This makes sustained vigilance in promoting Bitcoin adoption not just important, but essential.
The failure to remain vigilant could see Bitcoin’s potential diminished through undue regulation, controlled implementation (such as CBDCs—Central Bank Digital Currencies), or a failure to educate people about its benefits. Complacency would mean ceding victory to oppressive systems the world over.
This is why Bitcoin adoption isn’t solely a technological phenomenon—it is an ideological mission. To resist control, to safeguard freedom, and to empower individuals to thrive under self-sovereignty requires the active participation of people across all sectors of society.
Why Veterans Are Uniquely Positioned to Lead Veterans are inherently equipped to lead the charge in the fight for Bitcoin adoption and the broader battle for freedom. Their unique skillsets, shaped by discipline, adaptability, and leadership under pressure, are perfectly suited to this challenge. Here’s why veterans play a pivotal role in this movement: 1. Leadership and Vision: Veterans are natural leaders. They can galvanize communities toward a vision of financial independence, self-sovereignty, and empowerment through Bitcoin. Their experience coordinating efforts—whether on the battlefield or in humanitarian missions—allows them to efficiently communicate the importance of Bitcoin adoption. 2. Commitment to Freedom: The fight for Bitcoin adoption is deeply aligned with the ethos of service members: defending freedom at all costs. Veterans understand that true freedom cannot persist without vigilance, sacrifice, and a commitment to challenging oppressive systems. 3. Trust and Credibility: The military often fosters a level of trust and camaraderie among people. Veterans, therefore, have the clout to introduce Bitcoin to communities that may otherwise view it with skepticism. Their credibility as protectors of freedom gives them an edge in delivering Bitcoin’s message of liberation. 4. Adaptability in Uncertain Environments: Just as they’ve thrived in complex and chaotic environments, veterans are poised to navigate the evolving financial landscape. Bitcoin is still maturing and faces regulatory challenges, technological hurdles, and cultural misunderstandings. Veterans excel at adapting to change and finding solutions in challenging circumstances. 5. Mission-Driven Mindset: Every mission has an objective, and every objective demands clear focus. Veterans approach tasks methodically and with a commitment to success—the same mindset required to bridge the gap between Bitcoin skepticism and widespread adoption.
The Call to Action Veterans, the mission isn’t over. Humanity stands at a crossroads, and freedom is at stake. Bitcoin is not just a disruptive technology; it’s the torchbearer of liberty in a world increasingly dominated by centralized control. It’s time to take the skills, discipline, and passion forged in your service and channel them into this new fight: the fight for financial freedom and independence from a centralized system that has dominated the lives of billions of people for far too long.
Educate yourself about Bitcoin. Learn its nuances, its strengths, and its use cases. Share this knowledge with your communities, help dismantle misconceptions, and shine a light on the real promise of self-sovereignty. Become an anchor of leadership in this decentralized revolution.
For civilians: do not underestimate the importance of this mission. Every individual who adopts Bitcoin drives us one step closer to a world where personal freedom and economic empowerment are accessible to all. Join arms with veterans, thought leaders, and Bitcoin adopters to ensure the torch of liberty burns brightly.
Closing Thoughts Bitcoin is more than a financial revolution—it’s a movement for freedom. Veterans have long stood on the frontline for this cause, and today, they have an opportunity to champion it in a new way. With vigilance, resolve, and determination, humanity can achieve greater levels of freedom. But, as with all efforts to secure liberty, we must remain constantly committed to the mission. Remember: freedom demands eternal vigilance. So does Bitcoin.
Will you answer the call? Together, we can reshape the future as champions of sovereignty and bring the world closer to the ideals we all deserve.
OPERATION BITCOIN is a 501(c)(3) nonprofit on a mission to connect military veterans with Bitcoin.
You can directly support this mission by sharing our publication with a veteran today, zapping this article or donating at www.operationbitcoin.io

2025-01-19 04:48:31A new report from the National Sports Shooting Foundation (NSSF) shows that civilian firearm possession exceeded 490 million in 2022. The total from 1990 to 2022 is estimated at 491.3 million firearms. In 2022, over ten million firearms were domestically produced, leading to a total of 16,045,911 firearms available in the U.S. market.
Of these, 9,873,136 were handguns, 4,195,192 were rifles, and 1,977,583 were shotguns. Handgun availability aligns with the concealed carry and self-defense market, as all states allow concealed carry, with 29 having constitutional carry laws.

2025-05-06 06:00:25Album art didn’t always exist. In the early 1900s, recorded music was still a novelty, overshadowed by sales of sheet music. Early vinyl records were vastly different from what we think of today: discs were sold individually and could only hold up to four minutes of music per side. Sometimes, only one side of the record was used. One of the most popular records of 1910, for example, was “Come, Josephine, in My Flying Machine”: it clocked in at two minutes and 39 seconds.
The invention of album art can get lost in the story of technological mastery. But among all the factors that contributed to the rise of recorded music, it stands as one of the few that was wholly driven by creators themselves. Album art — first as marketing material, then as pure creative expression — turned an audio-only medium into a multi-sensory experience.
This is the story of the people who made music visible.

2025-05-06 05:49:01I don’t like garlic. It’s not a dislike for the taste in the moment, so much as an extreme dislike for the way it stays with you—sometimes for days—after a particularly garlicky meal.
Interestingly enough, both of my brothers love garlic. They roast it by itself and keep it at the ready so they can have a very strong garlic profile in their cooking. When I prepare a dish, I don’t even see garlic on the ingredient list. I’ve cut it out of my life so completely that my brain genuinely skips over it in recipes. While my brothers are looking for ways to sneak garlic into everything they make, I’m subconsciously avoiding it altogether.
A few years back, when I was digging intensely into how design systems mature, I stumbled on the concept of a design system origin story. There are two extreme origin stories and an infinite number of possibilities between. On one hand you have the grassroots system, where individuals working on digital products are simply trying to solve their own daily problems. They’re frustrated with having to go cut and paste elements from past designs or with recreating the same layouts over and over, so they start to work more systematically. On the other hand, you have the top down system, where leadership is directing teams to take a more systematic approach, often forming a small partially dedicated core team to tackle some centralized assets and guidelines for all to follow. The influences in those early days bias a design system in interesting and impactful ways.
We’ve established that there are a few types of bias that are either intentionally or unintentionally embedded into our design systems. Acknowledging this is a great first step. But, what’s the impact of this? Does it matter?
I believe there are a few impacts design system biases, but there’s one that stands out. The bias in your design system makes some individuals feel the system is meant for them and others feel it’s not. This is a problem because, a design system cannot live up to it’s expected value until it is broadly in use. If individuals feel your design system is not for them, the won’t use it. And, as you know, it doesn’t matter how good your design system is if nobody is using it.

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!”

2025-05-06 05:37:29Design can’t be effective when squeezed into a decades-old process.
When the Agile Manifesto was inked in 2001, it was supposed to spark a revolution, and it did: by 2023, 71% of US companies were using Agile. The simple list of commitments to collaboration and adaptiveness branched into frameworks such as Scrum and Kanban.
“Agile” was about having a responsive mindset, not about which process you followed, but it became about which process you followed.
Agile was designed for engineering teams but spread to whole companies. Scaled frameworks emerged to coordinate Scrum teams, with a sprawling training and certification industry. In 2022, the enterprise Agile transformation industry was predicted to reach $142 billion by 2032.

2025-01-14 01:31:12Bitcoin is more than money, more than an asset, and more than a store of value. Bitcoin is a Prime Mover, an enabler and it ignites imaginations. It certainly fueled an idea in my mind. The idea integrates sensors, computational prowess, actuated machinery, power conversion, and electronic communications to form an autonomous, machined creature roaming forests and harvesting the most widespread and least energy-dense fuel source available. I call it the Forest Walker and it eats wood, and mines Bitcoin.
I know what you're thinking. Why not just put Bitcoin mining rigs where they belong: in a hosted facility sporting electricity from energy-dense fuels like natural gas, climate-controlled with excellent data piping in and out? Why go to all the trouble building a robot that digests wood creating flammable gasses fueling an engine to run a generator powering Bitcoin miners? It's all about synergy.
Bitcoin mining enables the realization of multiple, seemingly unrelated, yet useful activities. Activities considered un-profitable if not for Bitcoin as the Prime Mover. This is much more than simply mining the greatest asset ever conceived by humankind. It’s about the power of synergy, which Bitcoin plays only one of many roles. The synergy created by this system can stabilize forests' fire ecology while generating multiple income streams. That’s the realistic goal here and requires a brief history of American Forest management before continuing.
Smokey The Bear
In 1944, the Smokey Bear Wildfire Prevention Campaign began in the United States. “Only YOU can prevent forest fires” remains the refrain of the Ad Council’s longest running campaign. The Ad Council is a U.S. non-profit set up by the American Association of Advertising Agencies and the Association of National Advertisers in 1942. It would seem that the U.S. Department of the Interior was concerned about pesky forest fires and wanted them to stop. So, alongside a national policy of extreme fire suppression they enlisted the entire U.S. population to get onboard via the Ad Council and it worked. Forest fires were almost obliterated and everyone was happy, right? Wrong.
Smokey is a fantastically successful bear so forest fires became so few for so long that the fuel load - dead wood - in forests has become very heavy. So heavy that when a fire happens (and they always happen) it destroys everything in its path because the more fuel there is the hotter that fire becomes. Trees, bushes, shrubs, and all other plant life cannot escape destruction (not to mention homes and businesses). The soil microbiology doesn’t escape either as it is burned away even in deeper soils. To add insult to injury, hydrophobic waxy residues condense on the soil surface, forcing water to travel over the ground rather than through it eroding forest soils. Good job, Smokey. Well done, Sir!
Most terrestrial ecologies are “fire ecologies”. Fire is a part of these systems’ fuel load and pest management. Before we pretended to “manage” millions of acres of forest, fires raged over the world, rarely damaging forests. The fuel load was always too light to generate fires hot enough to moonscape mountainsides. Fires simply burned off the minor amounts of fuel accumulated since the fire before. The lighter heat, smoke, and other combustion gasses suppressed pests, keeping them in check and the smoke condensed into a plant growth accelerant called wood vinegar, not a waxy cap on the soil. These fires also cleared out weak undergrowth, cycled minerals, and thinned the forest canopy, allowing sunlight to penetrate to the forest floor. Without a fire’s heat, many pine tree species can’t sow their seed. The heat is required to open the cones (the seed bearing structure) of Spruce, Cypress, Sequoia, Jack Pine, Lodgepole Pine and many more. Without fire forests can’t have babies. The idea was to protect the forests, and it isn't working.
So, in a world of fire, what does an ally look like and what does it do?
Meet The Forest Walker
For the Forest Walker to work as a mobile, autonomous unit, a solid platform that can carry several hundred pounds is required. It so happens this chassis already exists but shelved.
Introducing the Legged Squad Support System (LS3). A joint project between Boston Dynamics, DARPA, and the United States Marine Corps, the quadrupedal robot is the size of a cow, can carry 400 pounds (180 kg) of equipment, negotiate challenging terrain, and operate for 24 hours before needing to refuel. Yes, it had an engine. Abandoned in 2015, the thing was too noisy for military deployment and maintenance "under fire" is never a high-quality idea. However, we can rebuild it to act as a platform for the Forest Walker; albeit with serious alterations. It would need to be bigger, probably. Carry more weight? Definitely. Maybe replace structural metal with carbon fiber and redesign much as 3D printable parts for more effective maintenance.
The original system has a top operational speed of 8 miles per hour. For our purposes, it only needs to move about as fast as a grazing ruminant. Without the hammering vibrations of galloping into battle, shocks of exploding mortars, and drunken soldiers playing "Wrangler of Steel Machines", time between failures should be much longer and the overall energy consumption much lower. The LS3 is a solid platform to build upon. Now it just needs to be pulled out of the mothballs, and completely refitted with outboard equipment.
The Small Branch Chipper
When I say “Forest fuel load” I mean the dead, carbon containing litter on the forest floor. Duff (leaves), fine-woody debris (small branches), and coarse woody debris (logs) are the fuel that feeds forest fires. Walk through any forest in the United States today and you will see quite a lot of these materials. Too much, as I have described. Some of these fuel loads can be 8 tons per acre in pine and hardwood forests and up to 16 tons per acre at active logging sites. That’s some big wood and the more that collects, the more combustible danger to the forest it represents. It also provides a technically unlimited fuel supply for the Forest Walker system.
The problem is that this detritus has to be chewed into pieces that are easily ingestible by the system for the gasification process (we’ll get to that step in a minute). What we need is a wood chipper attached to the chassis (the LS3); its “mouth”.
A small wood chipper handling material up to 2.5 - 3.0 inches (6.3 - 7.6 cm) in diameter would eliminate a substantial amount of fuel. There is no reason for Forest Walker to remove fallen trees. It wouldn’t have to in order to make a real difference. It need only identify appropriately sized branches and grab them. Once loaded into the chipper’s intake hopper for further processing, the beast can immediately look for more “food”. This is essentially kindling that would help ignite larger logs. If it’s all consumed by Forest Walker, then it’s not present to promote an aggravated conflagration.
I have glossed over an obvious question: How does Forest Walker see and identify branches and such? LiDaR (Light Detection and Ranging) attached to Forest Walker images the local area and feed those data to onboard computers for processing. Maybe AI plays a role. Maybe simple machine learning can do the trick. One thing is for certain: being able to identify a stick and cause robotic appendages to pick it up is not impossible.
Great! We now have a quadrupedal robot autonomously identifying and “eating” dead branches and other light, combustible materials. Whilst strolling through the forest, depleting future fires of combustibles, Forest Walker has already performed a major function of this system: making the forest safer. It's time to convert this low-density fuel into a high-density fuel Forest Walker can leverage. Enter the gasification process.
The Gassifier
The gasifier is the heart of the entire system; it’s where low-density fuel becomes the high-density fuel that powers the entire system. Biochar and wood vinegar are process wastes and I’ll discuss why both are powerful soil amendments in a moment, but first, what’s gasification?
Reacting shredded carbonaceous material at high temperatures in a low or no oxygen environment converts the biomass into biochar, wood vinegar, heat, and Synthesis Gas (Syngas). Syngas consists primarily of hydrogen, carbon monoxide, and methane. All of which are extremely useful fuels in a gaseous state. Part of this gas is used to heat the input biomass and keep the reaction temperature constant while the internal combustion engine that drives the generator to produce electrical power consumes the rest.
Critically, this gasification process is “continuous feed”. Forest Walker must intake biomass from the chipper, process it to fuel, and dump the waste (CO2, heat, biochar, and wood vinegar) continuously. It cannot stop. Everything about this system depends upon this continual grazing, digestion, and excretion of wastes just as a ruminal does. And, like a ruminant, all waste products enhance the local environment.
When I first heard of gasification, I didn’t believe that it was real. Running an electric generator from burning wood seemed more akin to “conspiracy fantasy” than science. Not only is gasification real, it’s ancient technology. A man named Dean Clayton first started experiments on gasification in 1699 and in 1901 gasification was used to power a vehicle. By the end of World War II, there were 500,000 Syngas powered vehicles in Germany alone because of fossil fuel rationing during the war. The global gasification market was $480 billion in 2022 and projected to be as much as $700 billion by 2030 (Vantage Market Research). Gasification technology is the best choice to power the Forest Walker because it’s self-contained and we want its waste products.
Biochar: The Waste
Biochar (AKA agricultural charcoal) is fairly simple: it’s almost pure, solid carbon that resembles charcoal. Its porous nature packs large surface areas into small, 3 dimensional nuggets. Devoid of most other chemistry, like hydrocarbons (methane) and ash (minerals), biochar is extremely lightweight. Do not confuse it with the charcoal you buy for your grill. Biochar doesn’t make good grilling charcoal because it would burn too rapidly as it does not contain the multitude of flammable components that charcoal does. Biochar has several other good use cases. Water filtration, water retention, nutrient retention, providing habitat for microscopic soil organisms, and carbon sequestration are the main ones that we are concerned with here.
Carbon has an amazing ability to adsorb (substances stick to and accumulate on the surface of an object) manifold chemistries. Water, nutrients, and pollutants tightly bind to carbon in this format. So, biochar makes a respectable filter and acts as a “battery” of water and nutrients in soils. Biochar adsorbs and holds on to seven times its weight in water. Soil containing biochar is more drought resilient than soil without it. Adsorbed nutrients, tightly sequestered alongside water, get released only as plants need them. Plants must excrete protons (H+) from their roots to disgorge water or positively charged nutrients from the biochar's surface; it's an active process.
Biochar’s surface area (where adsorption happens) can be 500 square meters per gram or more. That is 10% larger than an official NBA basketball court for every gram of biochar. Biochar’s abundant surface area builds protective habitats for soil microbes like fungi and bacteria and many are critical for the health and productivity of the soil itself.
The “carbon sequestration” component of biochar comes into play where “carbon credits” are concerned. There is a financial market for carbon. Not leveraging that market for revenue is foolish. I am climate agnostic. All I care about is that once solid carbon is inside the soil, it will stay there for thousands of years, imparting drought resiliency, fertility collection, nutrient buffering, and release for that time span. I simply want as much solid carbon in the soil because of the undeniably positive effects it has, regardless of any climactic considerations.
Wood Vinegar: More Waste
Another by-product of the gasification process is wood vinegar (Pyroligneous acid). If you have ever seen Liquid Smoke in the grocery store, then you have seen wood vinegar. Principally composed of acetic acid, acetone, and methanol wood vinegar also contains ~200 other organic compounds. It would seem intuitive that condensed, liquefied wood smoke would at least be bad for the health of all living things if not downright carcinogenic. The counter intuition wins the day, however. Wood vinegar has been used by humans for a very long time to promote digestion, bowel, and liver health; combat diarrhea and vomiting; calm peptic ulcers and regulate cholesterol levels; and a host of other benefits.
For centuries humans have annually burned off hundreds of thousands of square miles of pasture, grassland, forest, and every other conceivable terrestrial ecosystem. Why is this done? After every burn, one thing becomes obvious: the almost supernatural growth these ecosystems exhibit after the burn. How? Wood vinegar is a component of this growth. Even in open burns, smoke condenses and infiltrates the soil. That is when wood vinegar shows its quality.
This stuff beefs up not only general plant growth but seed germination as well and possesses many other qualities that are beneficial to plants. It’s a pesticide, fungicide, promotes beneficial soil microorganisms, enhances nutrient uptake, and imparts disease resistance. I am barely touching a long list of attributes here, but you want wood vinegar in your soil (alongside biochar because it adsorbs wood vinegar as well).
The Internal Combustion Engine
Conversion of grazed forage to chemical, then mechanical, and then electrical energy completes the cycle. The ICE (Internal Combustion Engine) converts the gaseous fuel output from the gasifier to mechanical energy, heat, water vapor, and CO2. It’s the mechanical energy of a rotating drive shaft that we want. That rotation drives the electric generator, which is the heartbeat we need to bring this monster to life. Luckily for us, combined internal combustion engine and generator packages are ubiquitous, delivering a defined energy output given a constant fuel input. It’s the simplest part of the system.
The obvious question here is whether the amount of syngas provided by the gasification process will provide enough energy to generate enough electrons to run the entire system or not. While I have no doubt the energy produced will run Forest Walker's main systems the question is really about the electrons left over. Will it be enough to run the Bitcoin mining aspect of the system? Everything is a budget.
CO2 Production For Growth
Plants are lollipops. No matter if it’s a tree or a bush or a shrubbery, the entire thing is mostly sugar in various formats but mostly long chain carbohydrates like lignin and cellulose. Plants need three things to make sugar: CO2, H2O and light. In a forest, where tree densities can be quite high, CO2 availability becomes a limiting growth factor. It’d be in the forest interests to have more available CO2 providing for various sugar formation providing the organism with food and structure.
An odd thing about tree leaves, the openings that allow gasses like the ever searched for CO2 are on the bottom of the leaf (these are called stomata). Not many stomata are topside. This suggests that trees and bushes have evolved to find gasses like CO2 from below, not above and this further suggests CO2 might be in higher concentrations nearer the soil.
The soil life (bacterial, fungi etc.) is constantly producing enormous amounts of CO2 and it would stay in the soil forever (eventually killing the very soil life that produces it) if not for tidal forces. Water is everywhere and whether in pools, lakes, oceans or distributed in “moist” soils water moves towards to the moon. The water in the soil and also in the water tables below the soil rise toward the surface every day. When the water rises, it expels the accumulated gasses in the soil into the atmosphere and it’s mostly CO2. It’s a good bet on how leaves developed high populations of stomata on the underside of leaves. As the water relaxes (the tide goes out) it sucks oxygenated air back into the soil to continue the functions of soil life respiration. The soil “breathes” albeit slowly.
The gasses produced by the Forest Walker’s internal combustion engine consist primarily of CO2 and H2O. Combusting sugars produce the same gasses that are needed to construct the sugars because the universe is funny like that. The Forest Walker is constantly laying down these critical construction elements right where the trees need them: close to the ground to be gobbled up by the trees.
The Branch Drones
During the last ice age, giant mammals populated North America - forests and otherwise. Mastodons, woolly mammoths, rhinos, short-faced bears, steppe bison, caribou, musk ox, giant beavers, camels, gigantic ground-dwelling sloths, glyptodons, and dire wolves were everywhere. Many were ten to fifteen feet tall. As they crashed through forests, they would effectively cleave off dead side-branches of trees, halting the spread of a ground-based fire migrating into the tree crown ("laddering") which is a death knell for a forest.
These animals are all extinct now and forests no longer have any manner of pruning services. But, if we build drones fitted with cutting implements like saws and loppers, optical cameras and AI trained to discern dead branches from living ones, these drones could effectively take over pruning services by identifying, cutting, and dropping to the forest floor, dead branches. The dropped branches simply get collected by the Forest Walker as part of its continual mission.
The drones dock on the back of the Forest Walker to recharge their batteries when low. The whole scene would look like a grazing cow with some flies bothering it. This activity breaks the link between a relatively cool ground based fire and the tree crowns and is a vital element in forest fire control.
The Bitcoin Miner
Mining is one of four monetary incentive models, making this system a possibility for development. The other three are US Dept. of the Interior, township, county, and electrical utility company easement contracts for fuel load management, global carbon credits trading, and data set sales. All the above depends on obvious questions getting answered. I will list some obvious ones, but this is not an engineering document and is not the place for spreadsheets. How much Bitcoin one Forest Walker can mine depends on everything else. What amount of biomass can we process? Will that biomass flow enough Syngas to keep the lights on? Can the chassis support enough mining ASICs and supporting infrastructure? What does that weigh and will it affect field performance? How much power can the AC generator produce?
Other questions that are more philosophical persist. Even if a single Forest Walker can only mine scant amounts of BTC per day, that pales to how much fuel material it can process into biochar. We are talking about millions upon millions of forested acres in need of fuel load management. What can a single Forest Walker do? I am not thinking in singular terms. The Forest Walker must operate as a fleet. What could 50 do? 500?
What is it worth providing a service to the world by managing forest fuel loads? Providing proof of work to the global monetary system? Seeding soil with drought and nutrient resilience by the excretion, over time, of carbon by the ton? What did the last forest fire cost?
The Mesh Network
What could be better than one bitcoin mining, carbon sequestering, forest fire squelching, soil amending behemoth? Thousands of them, but then they would need to be able to talk to each other to coordinate position, data handling, etc. Fitted with a mesh networking device, like goTenna or Meshtastic LoRa equipment enables each Forest Walker to communicate with each other.
Now we have an interconnected fleet of Forest Walkers relaying data to each other and more importantly, aggregating all of that to the last link in the chain for uplink. Well, at least Bitcoin mining data. Since block data is lightweight, transmission of these data via mesh networking in fairly close quartered environs is more than doable. So, how does data transmit to the Bitcoin Network? How do the Forest Walkers get the previous block data necessary to execute on mining?
Back To The Chain
Getting Bitcoin block data to and from the network is the last puzzle piece. The standing presumption here is that wherever a Forest Walker fleet is operating, it is NOT within cell tower range. We further presume that the nearest Walmart Wi-Fi is hours away. Enter the Blockstream Satellite or something like it.
A separate, ground-based drone will have two jobs: To stay as close to the nearest Forest Walker as it can and to provide an antennae for either terrestrial or orbital data uplink. Bitcoin-centric data is transmitted to the "uplink drone" via the mesh networked transmitters and then sent on to the uplink and the whole flow goes in the opposite direction as well; many to one and one to many.
We cannot transmit data to the Blockstream satellite, and it will be up to Blockstream and companies like it to provide uplink capabilities in the future and I don't doubt they will. Starlink you say? What’s stopping that company from filtering out block data? Nothing because it’s Starlink’s system and they could decide to censor these data. It seems we may have a problem sending and receiving Bitcoin data in back country environs.
But, then again, the utility of this system in staunching the fuel load that creates forest fires is extremely useful around forested communities and many have fiber, Wi-Fi and cell towers. These communities could be a welcoming ground zero for first deployments of the Forest Walker system by the home and business owners seeking fire repression. In the best way, Bitcoin subsidizes the safety of the communities.
Sensor Packages
LiDaR
The benefit of having a Forest Walker fleet strolling through the forest is the never ending opportunity for data gathering. A plethora of deployable sensors gathering hyper-accurate data on everything from temperature to topography is yet another revenue generator. Data is valuable and the Forest Walker could generate data sales to various government entities and private concerns.
LiDaR (Light Detection and Ranging) can map topography, perform biomass assessment, comparative soil erosion analysis, etc. It so happens that the Forest Walker’s ability to “see,” to navigate about its surroundings, is LiDaR driven and since it’s already being used, we can get double duty by harvesting that data for later use. By using a laser to send out light pulses and measuring the time it takes for the reflection of those pulses to return, very detailed data sets incrementally build up. Eventually, as enough data about a certain area becomes available, the data becomes useful and valuable.
Forestry concerns, both private and public, often use LiDaR to build 3D models of tree stands to assess the amount of harvest-able lumber in entire sections of forest. Consulting companies offering these services charge anywhere from several hundred to several thousand dollars per square kilometer for such services. A Forest Walker generating such assessments on the fly while performing its other functions is a multi-disciplinary approach to revenue generation.
pH, Soil Moisture, and Cation Exchange Sensing
The Forest Walker is quadrupedal, so there are four contact points to the soil. Why not get a pH data point for every step it takes? We can also gather soil moisture data and cation exchange capacities at unheard of densities because of sampling occurring on the fly during commission of the system’s other duties. No one is going to build a machine to do pH testing of vast tracts of forest soils, but that doesn’t make the data collected from such an endeavor valueless. Since the Forest Walker serves many functions at once, a multitude of data products can add to the return on investment component.
Weather Data
Temperature, humidity, pressure, and even data like evapotranspiration gathered at high densities on broad acre scales have untold value and because the sensors are lightweight and don’t require large power budgets, they come along for the ride at little cost. But, just like the old mantra, “gas, grass, or ass, nobody rides for free”, these sensors provide potential revenue benefits just by them being present.
I’ve touched on just a few data genres here. In fact, the question for universities, governmental bodies, and other institutions becomes, “How much will you pay us to attach your sensor payload to the Forest Walker?”
Noise Suppression
Only you can prevent Metallica filling the surrounds with 120 dB of sound. Easy enough, just turn the car stereo off. But what of a fleet of 50 Forest Walkers operating in the backcountry or near a township? 500? 5000? Each one has a wood chipper, an internal combustion engine, hydraulic pumps, actuators, and more cooling fans than you can shake a stick at. It’s a walking, screaming fire-breathing dragon operating continuously, day and night, twenty-four hours a day, three hundred sixty-five days a year. The sound will negatively affect all living things and that impacts behaviors. Serious engineering consideration and prowess must deliver a silencing blow to the major issue of noise.
It would be foolish to think that a fleet of Forest Walkers could be silent, but if not a major design consideration, then the entire idea is dead on arrival. Townships would not allow them to operate even if they solved the problem of widespread fuel load and neither would governmental entities, and rightly so. Nothing, not man nor beast, would want to be subjected to an eternal, infernal scream even if it were to end within days as the fleet moved further away after consuming what it could. Noise and heat are the only real pollutants of this system; taking noise seriously from the beginning is paramount.
Fire Safety
A “fire-breathing dragon” is not the worst description of the Forest Walker. It eats wood, combusts it at very high temperatures and excretes carbon; and it does so in an extremely flammable environment. Bad mix for one Forest Walker, worse for many. One must take extreme pains to ensure that during normal operation, a Forest Walker could fall over, walk through tinder dry brush, or get pounded into the ground by a meteorite from Krypton and it wouldn’t destroy epic swaths of trees and baby deer. I envision an ultimate test of a prototype to include dowsing it in grain alcohol while it’s wrapped up in toilet paper like a pledge at a fraternity party. If it runs for 72 hours and doesn’t set everything on fire, then maybe outside entities won’t be fearful of something that walks around forests with a constant fire in its belly.
The Wrap
How we think about what can be done with and adjacent to Bitcoin is at least as important as Bitcoin’s economic standing itself. For those who will tell me that this entire idea is without merit, I say, “OK, fine. You can come up with something, too.” What can we plug Bitcoin into that, like a battery, makes something that does not work, work? That’s the lesson I get from this entire exercise. No one was ever going to hire teams of humans to go out and "clean the forest". There's no money in that. The data collection and sales from such an endeavor might provide revenues over the break-even point but investment demands Alpha in this day and age. But, plug Bitcoin into an almost viable system and, voilà! We tip the scales to achieve lift-off.
Let’s face it, we haven’t scratched the surface of Bitcoin’s forcing function on our minds. Not because it’s Bitcoin, but because of what that invention means. The question that pushes me to approach things this way is, “what can we create that one system’s waste is another system’s feedstock?” The Forest Walker system’s only real waste is the conversion of low entropy energy (wood and syngas) into high entropy energy (heat and noise). All other output is beneficial to humanity.
Bitcoin, I believe, is the first product of a new mode of human imagination. An imagination newly forged over the past few millennia of being lied to, stolen from, distracted and otherwise mis-allocated to a black hole of the nonsensical. We are waking up.
What I have presented is not science fiction. Everything I have described here is well within the realm of possibility. The question is one of viability, at least in terms of the detritus of the old world we find ourselves departing from. This system would take a non-trivial amount of time and resources to develop. I think the system would garner extensive long-term contracts from those who have the most to lose from wildfires, the most to gain from hyperaccurate data sets, and, of course, securing the most precious asset in the world. Many may not see it that way, for they seek Alpha and are therefore blind to other possibilities. Others will see only the possibilities; of thinking in a new way, of looking at things differently, and dreaming of what comes next.

@ e3ba5e1a:5e433365
2025-01-13 16:47:27My blog posts and reading material have both been on a decidedly economics-heavy slant recently. The topic today, incentives, squarely falls into the category of economics. However, when I say economics, I’m not talking about “analyzing supply and demand curves.” I’m talking about the true basis of economics: understanding how human beings make decisions in a world of scarcity.
A fair definition of incentive is “a reward or punishment that motivates behavior to achieve a desired outcome.” When most people think about economic incentives, they’re thinking of money. If I offer my son $5 if he washes the dishes, I’m incentivizing certain behavior. We can’t guarantee that he’ll do what I want him to do, but we can agree that the incentive structure itself will guide and ultimately determine what outcome will occur.
The great thing about monetary incentives is how easy they are to talk about and compare. “Would I rather make $5 washing the dishes or $10 cleaning the gutters?” But much of the world is incentivized in non-monetary ways too. For example, using the “punishment” half of the definition above, I might threaten my son with losing Nintendo Switch access if he doesn’t wash the dishes. No money is involved, but I’m still incentivizing behavior.
And there are plenty of incentives beyond our direct control! My son is also incentivized to not wash dishes because it’s boring, or because he has some friends over that he wants to hang out with, or dozens of other things. Ultimately, the conflicting array of different incentive structures placed on him will ultimately determine what actions he chooses to take.
Why incentives matter
A phrase I see often in discussions—whether they are political, parenting, economic, or business—is “if they could just do…” Each time I see that phrase, I cringe a bit internally. Usually, the underlying assumption of the statement is “if people would behave contrary to their incentivized behavior then things would be better.” For example:
- If my kids would just go to bed when I tell them, they wouldn’t be so cranky in the morning.
- If people would just use the recycling bin, we wouldn’t have such a landfill problem.
- If people would just stop being lazy, our team would deliver our project on time.
In all these cases, the speakers are seemingly flummoxed as to why the people in question don’t behave more rationally. The problem is: each group is behaving perfectly rationally.
- The kids have a high time preference, and care more about the joy of staying up now than the crankiness in the morning. Plus, they don’t really suffer the consequences of morning crankiness, their parents do.
- No individual suffers much from their individual contribution to a landfill. If they stopped growing the size of the landfill, it would make an insignificant difference versus the amount of effort they need to engage in to properly recycle.
- If a team doesn’t properly account for the productivity of individuals on a project, each individual receives less harm from their own inaction. Sure, the project may be delayed, company revenue may be down, and they may even risk losing their job when the company goes out of business. But their laziness individually won’t determine the entirety of that outcome. By contrast, they greatly benefit from being lazy by getting to relax at work, go on social media, read a book, or do whatever else they do when they’re supposed to be working.
My point here is that, as long as you ignore the reality of how incentives drive human behavior, you’ll fail at getting the outcomes you want.
If everything I wrote up until now made perfect sense, you understand the premise of this blog post. The rest of it will focus on a bunch of real-world examples to hammer home the point, and demonstrate how versatile this mental model is.
Running a company
Let’s say I run my own company, with myself as the only employee. My personal revenue will be 100% determined by my own actions. If I decide to take Tuesday afternoon off and go fishing, I’ve chosen to lose that afternoon’s revenue. Implicitly, I’ve decided that the enjoyment I get from an afternoon of fishing is greater than the potential revenue. You may think I’m being lazy, but it’s my decision to make. In this situation, the incentive–money–is perfectly aligned with my actions.
Compare this to a typical company/employee relationship. I might have a bank of Paid Time Off (PTO) days, in which case once again my incentives are relatively aligned. I know that I can take off 15 days throughout the year, and I’ve chosen to use half a day for the fishing trip. All is still good.
What about unlimited time off? Suddenly incentives are starting to misalign. I don’t directly pay a price for not showing up to work on Tuesday. Or Wednesday as well, for that matter. I might ultimately be fired for not doing my job, but that will take longer to work its way through the system than simply not making any money for the day taken off.
Compensation overall falls into this misaligned incentive structure. Let’s forget about taking time off. Instead, I work full time on a software project I’m assigned. But instead of using the normal toolchain we’re all used to at work, I play around with a new programming language. I get the fun and joy of playing with new technology, and potentially get to pad my resume a bit when I’m ready to look for a new job. But my current company gets slower results, less productivity, and is forced to subsidize my extracurricular learning.
When a CEO has a bonus structure based on profitability, he’ll do everything he can to make the company profitable. This might include things that actually benefit the company, like improving product quality, reducing internal red tape, or finding cheaper vendors. But it might also include destructive practices, like slashing the R\&D budget to show massive profits this year, in exchange for a catastrophe next year when the next version of the product fails to ship.
Or my favorite example. My parents owned a business when I was growing up. They had a back office where they ran operations like accounting. All of the furniture was old couches from our house. After all, any money they spent on furniture came right out of their paychecks! But in a large corporate environment, each department is generally given a budget for office furniture, a budget which doesn’t roll over year-to-year. The result? Executives make sure to spend the entire budget each year, often buying furniture far more expensive than they would choose if it was their own money.
There are plenty of details you can quibble with above. It’s in a company’s best interest to give people downtime so that they can come back recharged. Having good ergonomic furniture can in fact increase productivity in excess of the money spent on it. But overall, the picture is pretty clear: in large corporate structures, you’re guaranteed to have mismatches between the company’s goals and the incentive structure placed on individuals.
Using our model from above, we can lament how lazy, greedy, and unethical the employees are for doing what they’re incentivized to do instead of what’s right. But that’s simply ignoring the reality of human nature.
Moral hazard
Moral hazard is a situation where one party is incentivized to take on more risk because another party will bear the consequences. Suppose I tell my son when he turns 21 (or whatever legal gambling age is) that I’ll cover all his losses for a day at the casino, but he gets to keep all the winnings.
What do you think he’s going to do? The most logical course of action is to place the largest possible bets for as long as possible, asking me to cover each time he loses, and taking money off the table and into his bank account each time he wins.
But let’s look at a slightly more nuanced example. I go to a bathroom in the mall. As I’m leaving, I wash my hands. It will take me an extra 1 second to turn off the water when I’m done washing. That’s a trivial price to pay. If I don’t turn off the water, the mall will have to pay for many liters of wasted water, benefiting no one. But I won’t suffer any consequences at all.
This is also a moral hazard, but most people will still turn off the water. Why? Usually due to some combination of other reasons such as:
- We’re so habituated to turning off the water that we don’t even consider not turning it off. Put differently, the mental effort needed to not turn off the water is more expensive than the 1 second of time to turn it off.
- Many of us have been brought up with a deep guilt about wasting resources like water. We have an internal incentive structure that makes the 1 second to turn off the water much less costly than the mental anguish of the waste we created.
- We’re afraid we’ll be caught by someone else and face some kind of social repercussions. (Or maybe more than social. Are you sure there isn’t a law against leaving the water tap on?)
Even with all that in place, you may notice that many public bathrooms use automatic water dispensers. Sure, there’s a sanitation reason for that, but it’s also to avoid this moral hazard.
A common denominator in both of these is that the person taking the action that causes the liability (either the gambling or leaving the water on) is not the person who bears the responsibility for that liability (the father or the mall owner). Generally speaking, the closer together the person making the decision and the person incurring the liability are, the smaller the moral hazard.
It’s easy to demonstrate that by extending the casino example a bit. I said it was the father who was covering the losses of the gambler. Many children (though not all) would want to avoid totally bankrupting their parents, or at least financially hurting them. Instead, imagine that someone from the IRS shows up at your door, hands you a credit card, and tells you you can use it at a casino all day, taking home all the chips you want. The money is coming from the government. How many people would put any restriction on how much they spend?
And since we’re talking about the government already…
Government moral hazards
As I was preparing to write this blog post, the California wildfires hit. The discussions around those wildfires gave a huge number of examples of moral hazards. I decided to cherry-pick a few for this post.
The first and most obvious one: California is asking for disaster relief funds from the federal government. That sounds wonderful. These fires were a natural disaster, so why shouldn’t the federal government pitch in and help take care of people?
The problem is, once again, a moral hazard. In the case of the wildfires, California and Los Angeles both had ample actions they could have taken to mitigate the destruction of this fire: better forest management, larger fire department, keeping the water reservoirs filled, and probably much more that hasn’t come to light yet.
If the federal government bails out California, it will be a clear message for the future: your mistakes will be fixed by others. You know what kind of behavior that incentivizes? More risky behavior! Why spend state funds on forest management and extra firefighters—activities that don’t win politicians a lot of votes in general—when you could instead spend it on a football stadium, higher unemployment payments, or anything else, and then let the feds cover the cost of screw-ups.
You may notice that this is virtually identical to the 2008 “too big to fail” bail-outs. Wall Street took insanely risky behavior, reaped huge profits for years, and when they eventually got caught with their pants down, the rest of us bailed them out. “Privatizing profits, socializing losses.”
And here’s the absolute best part of this: I can’t even truly blame either California or Wall Street. (I mean, I do blame them, I think their behavior is reprehensible, but you’ll see what I mean.) In a world where the rules of the game implicitly include the bail-out mentality, you would be harming your citizens/shareholders/investors if you didn’t engage in that risky behavior. Since everyone is on the hook for those socialized losses, your best bet is to maximize those privatized profits.
There’s a lot more to government and moral hazard, but I think these two cases demonstrate the crux pretty solidly. But let’s leave moral hazard behind for a bit and get to general incentivization discussions.
Non-monetary competition
At least 50% of the economics knowledge I have comes from the very first econ course I took in college. That professor was amazing, and had some very colorful stories. I can’t vouch for the veracity of the two I’m about to share, but they definitely drive the point home.
In the 1970s, the US had an oil shortage. To “fix” this problem, they instituted price caps on gasoline, which of course resulted in insufficient gasoline. To “fix” this problem, they instituted policies where, depending on your license plate number, you could only fill up gas on certain days of the week. (Irrelevant detail for our point here, but this just resulted in people filling up their tanks more often, no reduction in gas usage.)
Anyway, my professor’s wife had a friend. My professor described in great detail how attractive this woman was. I’ll skip those details here since this is a PG-rated blog. In any event, she never had any trouble filling up her gas tank any day of the week. She would drive up, be told she couldn’t fill up gas today, bat her eyes at the attendant, explain how helpless she was, and was always allowed to fill up gas.
This is a demonstration of non-monetary compensation. Most of the time in a free market, capitalist economy, people are compensated through money. When price caps come into play, there’s a limit to how much monetary compensation someone can receive. And in that case, people find other ways of competing. Like this woman’s case: through using flirtatious behavior to compensate the gas station workers to let her cheat the rules.
The other example was much more insidious. Santa Monica had a problem: it was predominantly wealthy and white. They wanted to fix this problem, and decided to put in place rent controls. After some time, they discovered that Santa Monica had become wealthier and whiter, the exact opposite of their desired outcome. Why would that happen?
Someone investigated, and ended up interviewing a landlady that demonstrated the reason. She was an older white woman, and admittedly racist. Prior to the rent controls, she would list her apartments in the newspaper, and would be legally obligated to rent to anyone who could afford it. Once rent controls were in place, she took a different tact. She knew that she would only get a certain amount for the apartment, and that the demand for apartments was higher than the supply. That meant she could be picky.
She ended up finding tenants through friends-of-friends. Since it wasn’t an official advertisement, she wasn’t legally required to rent it out if someone could afford to pay. Instead, she got to interview people individually and then make them an offer. Normally, that would have resulted in receiving a lower rental price, but not under rent controls.
So who did she choose? A young, unmarried, wealthy, white woman. It made perfect sense. Women were less intimidating and more likely to maintain the apartment better. Wealthy people, she determined, would be better tenants. (I have no idea if this is true in practice or not, I’m not a landlord myself.) Unmarried, because no kids running around meant less damage to the property. And, of course, white. Because she was racist, and her incentive structure made her prefer whites.
You can deride her for being racist, I won’t disagree with you. But it’s simply the reality. Under the non-rent-control scenario, her profit motive for money outweighed her racism motive. But under rent control, the monetary competition was removed, and she was free to play into her racist tendencies without facing any negative consequences.
Bureaucracy
These were the two examples I remember for that course. But non-monetary compensation pops up in many more places. One highly pertinent example is bureaucracies. Imagine you have a government office, or a large corporation’s acquisition department, or the team that apportions grants at a university. In all these cases, you have a group of people making decisions about handing out money that has no monetary impact on them. If they give to the best qualified recipients, they receive no raises. If they spend the money recklessly on frivolous projects, they face no consequences.
Under such an incentivization scheme, there’s little to encourage the bureaucrats to make intelligent funding decisions. Instead, they’ll be incentivized to spend the money where they recognize non-monetary benefits. This is why it’s so common to hear about expensive meals, gift bags at conferences, and even more inappropriate ways of trying to curry favor with those that hold the purse strings.
Compare that ever so briefly with the purchases made by a small mom-and-pop store like my parents owned. Could my dad take a bribe to buy from a vendor who’s ripping him off? Absolutely he could! But he’d lose more on the deal than he’d make on the bribe, since he’s directly incentivized by the deal itself. It would make much more sense for him to go with the better vendor, save $5,000 on the deal, and then treat himself to a lavish $400 meal to celebrate.
Government incentivized behavior
This post is getting longer in the tooth than I’d intended, so I’ll finish off with this section and make it a bit briefer. Beyond all the methods mentioned above, government has another mechanism for modifying behavior: through directly changing incentives via legislation, regulation, and monetary policy. Let’s see some examples:
- Artificial modification of interest rates encourages people to take on more debt than they would in a free capital market, leading to malinvestment and a consumer debt crisis, and causing the boom-bust cycle we all painfully experience.
- Going along with that, giving tax breaks on interest payments further artificially incentivizes people to take on debt that they wouldn’t otherwise.
- During COVID-19, at some points unemployment benefits were greater than minimum wage, incentivizing people to rather stay home and not work than get a job, leading to reduced overall productivity in the economy and more printed dollars for benefits. In other words, it was a perfect recipe for inflation.
- The tax code gives deductions to “help” people. That might be true, but the real impact is incentivizing people to make decisions they wouldn’t have otherwise. For example, giving out tax deductions on children encourages having more kids. Tax deductions on childcare and preschools incentivizes dual-income households. Whether or not you like the outcomes, it’s clear that it’s government that’s encouraging these outcomes to happen.
- Tax incentives cause people to engage in behavior they wouldn’t otherwise (daycare+working mother, for example).
- Inflation means that the value of your money goes down over time, which encourages people to spend more today, when their money has a larger impact. (Milton Friedman described this as high living.)
Conclusion
The idea here is simple, and fully encapsulated in the title: incentives determine outcomes. If you want to know how to get a certain outcome from others, incentivize them to want that to happen. If you want to understand why people act in seemingly irrational ways, check their incentives. If you’re confused why leaders (and especially politicians) seem to engage in destructive behavior, check their incentives.
We can bemoan these realities all we want, but they are realities. While there are some people who have a solid internal moral and ethical code, and that internal code incentivizes them to behave against their externally-incentivized interests, those people are rare. And frankly, those people are self-defeating. People should take advantage of the incentives around them. Because if they don’t, someone else will.
(If you want a literary example of that last comment, see the horse in Animal Farm.)
How do we improve the world under these conditions? Make sure the incentives align well with the overall goals of society. To me, it’s a simple formula:
- Focus on free trade, value for value, as the basis of a society. In that system, people are always incentivized to provide value to other people.
- Reduce the size of bureaucracies and large groups of all kinds. The larger an organization becomes, the farther the consequences of decisions are from those who make them.
- And since the nature of human beings will be to try and create areas where they can control the incentive systems to their own benefits, make that as difficult as possible. That comes in the form of strict limits on government power, for example.
And even if you don’t want to buy in to this conclusion, I hope the rest of the content was educational, and maybe a bit entertaining!

@ 3f770d65:7a745b24
2025-01-12 21:03:36I’ve been using Notedeck for several months, starting with its extremely early and experimental alpha versions, all the way to its current, more stable alpha releases. The journey has been fascinating, as I’ve had the privilege of watching it evolve from a concept into a functional and promising tool.
In its earliest stages, Notedeck was raw—offering glimpses of its potential but still far from practical for daily use. Even then, the vision behind it was clear: a platform designed to redefine how we interact with Nostr by offering flexibility and power for all users.
I'm very bullish on Notedeck. Why? Because Will Casarin is making it! Duh! 😂
Seriously though, if we’re reimagining the web and rebuilding portions of the Internet, it’s important to recognize the potential of Notedeck. If Nostr is reimagining the web, then Notedeck is reimagining the Nostr client.
Notedeck isn’t just another Nostr app—it’s more a Nostr browser that functions more like an operating system with micro-apps. How cool is that?
Much like how Google's Chrome evolved from being a web browser with a task manager into ChromeOS, a full blown operating system, Notedeck aims to transform how we interact with the Nostr. It goes beyond individual apps, offering a foundation for a fully integrated ecosystem built around Nostr.
As a Nostr evangelist, I love to scream INTEROPERABILITY and tout every application's integrations. Well, Notedeck has the potential to be one of the best platforms to showcase these integrations in entirely new and exciting ways.
Do you want an Olas feed of images? Add the media column.
Do you want a feed of live video events? Add the zap.stream column.
Do you want Nostr Nests or audio chats? Add that column to your Notedeck.
Git? Email? Books? Chat and DMs? It's all possible.
Not everyone wants a super app though, and that’s okay. As with most things in the Nostr ecosystem, flexibility is key. Notedeck gives users the freedom to choose how they engage with it—whether it’s simply following hashtags or managing straightforward feeds. You'll be able to tailor Notedeck to fit your needs, using it as extensively or minimally as you prefer.
Notedeck is designed with a local-first approach, utilizing Nostr content stored directly on your device via the local nostrdb. This will enable a plethora of advanced tools such as search and filtering, the creation of custom feeds, and the ability to develop personalized algorithms across multiple Notedeck micro-applications—all with unparalleled flexibility.
Notedeck also supports multicast. Let's geek out for a second. Multicast is a method of communication where data is sent from one source to multiple destinations simultaneously, but only to devices that wish to receive the data. Unlike broadcast, which sends data to all devices on a network, multicast targets specific receivers, reducing network traffic. This is commonly used for efficient data distribution in scenarios like streaming, conferencing, or large-scale data synchronization between devices.
In a local first world where each device holds local copies of your nostr nodes, and each device transparently syncs with each other on the local network, each node becomes a backup. Your data becomes antifragile automatically. When a node goes down it can resync and recover from other nodes. Even if not all nodes have a complete collection, negentropy can pull down only what is needed from each device. All this can be done without internet.
-Will Casarin
In the context of Notedeck, multicast would allow multiple devices to sync their Nostr nodes with each other over a local network without needing an internet connection. Wild.
Notedeck aims to offer full customization too, including the ability to design and share custom skins, much like Winamp. Users will also be able to create personalized columns and, in the future, share their setups with others. This opens the door for power users to craft tailored Nostr experiences, leveraging their expertise in the protocol and applications. By sharing these configurations as "Starter Decks," they can simplify onboarding and showcase the best of Nostr’s ecosystem.
Nostr’s “Other Stuff” can often be difficult to discover, use, or understand. Many users doesn't understand or know how to use web browser extensions to login to applications. Let's not even get started with nsecbunkers. Notedeck will address this challenge by providing a native experience that brings these lesser-known applications, tools, and content into a user-friendly and accessible interface, making exploration seamless. However, that doesn't mean Notedeck should disregard power users that want to use nsecbunkers though - hint hint.
For anyone interested in watching Nostr be developed live, right before your very eyes, Notedeck’s progress serves as a reminder of what’s possible when innovation meets dedication. The current alpha is already demonstrating its ability to handle complex use cases, and I’m excited to see how it continues to grow as it moves toward a full release later this year.

2025-05-06 05:17:07*Holtec új atomenergetikai együttműködése Utah államban*
Az amerikai Holtec International stratégiai megállapodást kötött Utah állammal és a Hi Tech Solutions nukleáris szolgáltatóval, hogy elősegítse saját fejlesztésű, SMR-300 típusú kis moduláris reaktorainak (SMR) telepítését Utahban és az Egyesült Államok Mountain West régiójában. A megállapodás értelmében 2028-ig állandó képzési központot hoznak létre Utahban, amely az üzemeltetéshez, karbantartáshoz és az új generációs nukleáris technológiákhoz szükséges munkaerő képzését célozza, szoros együttműködésben helyi egyetemekkel, főiskolákkal és szakiskolákkal.
A projekt Utah állam energetikai stratégiájának („Operation Gigawatt” és „Built Here”) része, amely a következő tíz évben megduplázná az állam energiatermelését, kiemelt szerepet szánva a tiszta nukleáris energiának. A Holtec Utah-t választotta nyugati gyártóbázisának is, ezzel erősítve az amerikai nukleáris ellátási láncot és hosszú távú munkahelyeket teremtve. A cég a 2030-as években akár 4 GW összkapacitású SMR-300 telepítését tervezi főként Utahban és Wyomingban.
Az SMR-300 egy nyomottvizes reaktor, amely 300 MW villamos vagy 1050 MW hőteljesítményt biztosít, és a Holtec tervei szerint kulcsszerepet játszhat a tiszta, szén-dioxid-mentes energiatermelésben.
*Amerikai SMR-piac helyzete*
Az SMR-technológia az utóbbi években került a figyelem középpontjába, mivel gyorsabban és olcsóbban telepíthető, mint a hagyományos atomerőművek, és lehetőséget kínál magánbefektetők számára is. Ugyanakkor az első amerikai SMR-projekt, a NuScale és a Utah Associated Municipal Power Systems közös beruházása költségnövekedés miatt meghiúsult, ami rávilágított a technológia gazdasági kihívásaira.
Nemzetközi fejlemények és további hírek
- Az ausztrál Okapi Resources és az Urenco együttműködési megállapodást kötött új urán dúsítási technológia fejlesztésére, amely tisztább és olcsóbb dúsítási eljárást ígér.
- Az Argonne National Laboratory sikeresen kicserélt egy 30 éves kulcsfontosságú alkatrészt a nátriumhűtésű gyorsreaktor-tesztberendezésében, ami hozzájárulhat a gyorsreaktor-technológia fejlesztéséhez az Egyesült Államokban.
- A Tennessee Egyetem ösztöndíjprogramot indít a Fülöp-szigeteki nukleáris szakemberek képzésére, támogatva ezzel a délkelet-ázsiai ország nukleáris energiafejlesztési törekvéseit.
- Bulgáriában a Westinghouse Electric Company helyi beszállítókkal kötött megállapodásokat két új AP1000 típusú reaktor építéséhez a kozloduji atomerőműben.

2025-05-06 03:01:47Introduction
In the ancient times of Israel, masculinity found its true embodiment in the courageous story of Daniel. Amidst the foreign land of Babylon, Daniel stood firm in his convictions, showcasing strength, and dedication to his beliefs.
Despite living in a culture that sought to diminish his faith, Daniel refused to bow before idols or false deities. His defiance challenged societal expectations, revealing a masculinity that transcended worldly norms. Rooted in his unshakable belief in the one true God, Daniel's resolve remained unyielding. Facing the wrath of the king, Daniel fearlessly stood before Nebuchadnezzar, humbly declaring his allegiance to God alone. Cast into a blazing furnace as punishment, Daniel emerged unharmed. God's angel shielded him from the scorching flames, proving that his faith made him invincible. Witnessing this display of masculinity, Nebuchadnezzar acknowledged the greatness of Daniel's God, bringing about a profound transformation.
Daniel's story serves as a testament to the essence of masculinity—a resolute dedication to one's convictions, the courage to defy societal expectations, and a commitment to truth. His faith and devotion inspire generations, exemplifying the power of masculine conviction.
There have been countless instances throughout history where acts of courage have taken place on a spectrum. Although both men and women can display such acts, history has shown that resolve, courage, and bravery have predominantly resided within the realm of masculinity. The Apostle Paul himself concluded the book of 1 Corinthians by saying, "Be watchful, stand firm in the faith, act like men, be strong. Let all that you do be done in love" (16:13-14). By combining this passage with the numerous accounts of provision, battle, sacrifice, and honor, it becomes evident that God has designed inherent and very important differences within the male gender.
The Bible presents us with inspiring examples of both courageous women, such as Deborah, Rahab, and Esther, and valiant men, including Joshua, Gideon, Samson, David, Jonathan, Nehemiah, the Prophets, the twelve Apostles, and above all, Jesus Himself. While these accounts acknowledge the remarkable contributions of women, they predominantly highlight the male figures who exemplify strength, boldness, courage, and a resolute sense of responsibility. Throughout its pages, the Bible paints a vivid picture of masculinity's profound impact and enduring significance which we must embrace.
Jesus’ Masculinity
Jesus exhibited remarkable courage throughout many of his acts, and it is through his expression of masculinity that this courage shines even brighter. Jesus' masculinity played a crucial role in enabling him to display great bravery and determination in fulfilling his mission. However, it's important to note that Jesus redefines masculinity beyond physical strength or dominance, embracing resilience, self-sacrifice, and unyielding conviction as its defining qualities.
Jesus' courage stemmed from his deep understanding of his purpose and his unshakable faith in his Father's plan. He fearlessly challenged the religious authorities of his time, calling out hypocrisy and speaking truth to power. Despite facing opposition and hostility, Jesus stood firm in his convictions, undeterred by the threats and ridicule he encountered. Jesus' embodiment of masculinity highlights the transformative power it can have when rooted in love and compassion.
Modern Culture Poisoning the Church
It is important to realize the true masculinity of Jesus and the example that he has set for us in this regard. Unfortunately, I often see a tendency nowadays to downplay Jesus' masculinity and instead depict Him in a more feminized manner.
In both our culture and the modern church, there is a tendency to present a version of Jesus that deviates from the biblical portrayal. Perhaps you've come across people who refer to Jesus as their "best friend" or even draw comparisons between their relationship with Him and that of a "boyfriend.” This is in fact very unbiblical. The Bible never presents our love for God using such romantic or erotic language. While the men depicted in Scripture certainly loved God, they were never portrayed as being desperate for Him or romantically in love with Him. People are often taught a very shallow and weak portrayal of Him.
In the United States, particularly in the context of flourishing Protestantism, the shift from considering the community as a whole to focusing on the individual has led to a rise in strong individualistic beliefs which has resulted in a diminished sense of community within the Catholic Church. When the focal point of Catholicism becomes "Jesus and me," it opens the door to a mindset of being "spiritual" rather than "religious.” Attending church becomes a matter of personal choice, and faith no longer necessarily influences or intersects with areas such as business or politics. The sole emphasis becomes on one's personal relationship with Christ, prioritizing individual salvation over communal or global redemption. The vision of the kingdom of God taking shape on earth also becomes less urgent, as the emphasis shifts towards a faith centered on transcendence, emotions, and sentiment, rather than tangible actions.
The perception of Jesus' masculinity has been negatively impacted by the trend of feminizing Him, which has contributed to a decline in the courage displayed by men today. This shift can be attributed to various factors that have influenced societal perspectives.
In contrast to the promises of Jesus, which include suffering, trials, and pain, it is often only presented to them that Christianity is the solution to these hardships. Instead of acknowledging the reality of challenges, the contemporary portrayal of Christianity tends to market it as the antidote to suffering and pain. It is important to recognize and reflect upon the significant difference between how Jesus called His disciples and the prevailing emphasis on personal relationships with Him today. Instead of inviting them to have a personal connection, He simply said, "Follow me." Understanding this distinction is crucial in our understanding of Jesus' call to discipleship. "Follow me" implies a sense of purpose, a shared mission or goal to pursue. This contrast highlights the divergence between the original intent of discipleship and the way it is often portrayed around me nowadays.
I want to emphasize that I am by no means denying the significance of having a personal relationship with Christ. On the contrary, I am simply highlighting the importance of recognizing that personal relationships, including our relationship with Christ, require more than just superficial connections. They demand a deep sense of faith, trust, and communion with Him. Drawing inspiration from the courageous example of Jesus, who fearlessly confronted societal norms and spoke truth to power, our relationship with Him can empower us to embrace courage in our own lives. Just as Jesus fearlessly faced opposition, persecution, and ultimately sacrificed Himself for the sake of others, our connection with Him can embolden us to stand up for what is right, to live out our faith boldly, and to face life's challenges with strength. It is not a casual or complacent association but a courageous and transformative bond that empowers us to live out our faith with conviction and to impact the world around us positively.
As modern sermons take center stage, it's become apparent that there is a tendency to downplay the contrasts found in the teachings of the Bible. As mentions of heaven and hell, sin and life, grace and justice, as well as the analogies involving battles and soldiers for Christ have always been very prevalent, they have become way less common nowadays. We hear fewer calls for Catholics to embrace their crosses and passionately commit themselves to the cause of the gospel and the well-being of others. Instead, the spotlight has shifted towards how the gospel can serve as a tool for personal growth and fulfillment, focusing on self-realization. The gospel is often presented as a therapeutic treatment rather than a heroic challenge. The emphasis lies on the rewards rather than the obstacles, creating the idea of all gain, no pain (lol).
The rise of praise and worship music has also brought about significant changes in people's perception of Christ. While traditional hymns focused on singing about God, emphasizing His greatness, power, and distinctiveness, praise and worship music takes a different approach. It presents God as a close companion, an intimate presence by our side, emphasizing His love and care for us. This shift in emphasis, while not inherently negative, certainly plays a substantial role in shaping our understanding of Christ's nature and relationship with us.
Jesus is the Epitome of Masculinity
I believe Jesus stands as the epitome of masculinity, offering an unrivaled example for men to emulate. Through His life and teachings, He reveals the true essence of what it means to be a man. He leads with courage, facing challenges head-on without hesitation. His fearlessness shines through as He confronts opposition and stands firm in His convictions. Moreover, His love is not self-serving but sacrificial, displayed vividly through His ultimate act of giving His own life for the sake of others. And in the face of adversity, His resolve remains unshakeable, inspiring men to stand strong in their beliefs and principles. Jesus, in His entirety, embodies the essence of true masculinity, setting an unparalleled standard that us men must aspire to.
Around me, I’m often seeing a tendency to shy away from addressing challenging subjects with resolute conviction. Rather than speaking with clarity and certainty, there is a preference for using vague language and ambiguous statements to navigate sensitive issues. In stark contrast, Jesus stood firmly and fearlessly, fearlessly proclaiming His truth. His words shook the foundations of societal norms, demanding radical commitment from His followers. True boldness lies in the courage to speak truth, even when faced with opposition and adversity.
Boldness is a very masculine characteristic. While some may argue that boldness is not exclusive to gender, the Bible primarily associates this characteristic with men. On the other hand, the beauty of women is highlighted through the importance of a gentle and quiet spirit, which also very much holds great value in the eyes of God. 1 Peter 3:4 addressing woman and wives, "Let your adorning be the hidden person of the heart with the imperishable beauty of a gentle and quiet spirit, which in God's sight is very precious." This reminds us that inner qualities such as a gentle and tranquil demeanor also hold significant worth and are highly esteemed.
As Jesus exemplified true boldness, courageously speaking God's truth regardless of the consequences. His courage serves as the ultimate model of masculinity, inspiring men to fearlessly pursue God's will. Jesus exemplified bravery, rooted in His deep reverence for God. Unlike the fear of man, which arises from sin, Jesus' bravery stemmed from His love for God. His resolute posture and authoritative responses to godless men demonstrated a masculinity untainted by timidity. Jesus taught us to lead with courage, grounded in reverence for God and faith in His sovereignty.
In a culture where love is often misrepresented, Jesus' sacrificial love stands as the true definition. Love, as demonstrated by Jesus, goes beyond superficial feelings; it entails sacrificial commitment. Jesus willingly laid down His life for His bride, the Church, showcasing the essence of true masculinity. Men are called to sacrificially love their wives, mirroring Christ's example. This selfless love forms the foundation for men to protect, nurture, and fight for those entrusted to their care.
Christ's resolve was the driving force behind the cross, demonstrating His commitment to fulfill His mission. His choice to embrace the cross, knowing the suffering and wrath He would endure, showcases resolute masculinity. In history, heroic moments of perseverance are predominantly marked by male resolve. The biological advantage provided by testosterone further supports men's capacity for enduring resolve. Jesus' resolve to save His people from sin teaches men to stand firm in the face of challenges, abiding in their commitment to their calling.
Restoring the Church's Boldness and Reclaiming Biblical Masculinity and Femininity
The landscape of the Church has undergone a significant transformation, moving away from its historic expression of Christianity. We've witnessed a shift from powerful, convicting sermons to soft, TED-talk style infotainment. Classic hymns highlighting doctrine, sacrifice, and piety have been replaced by emotionally driven love songs that resemble romantic ballads. It's clear that the local church has undergone a real emasculation.
This departure from biblical foundations has contributed to a great deal of confusion within the Church, particularly concerning the understanding of biblical manhood and womanhood. The increasing push for egalitarianism has led to women fighting for leadership roles, while men find themselves adrift without clear guidance regarding their responsibilities in marriage, the church, and the family. I believe this confusion and distortion of gender roles to be the enemy's central strategy for our generation. By infiltrating the Church with a heightened emphasis on feminine emotion, the enemy has left us unprepared for moments requiring masculine boldness, fearlessness, sacrifice, and resolve.
We must acknowledge that there is a difference between a surface-level expression of faith and the profound conviction displayed by those facing intense trials. The challenges and hardships that people face in the midst of adversity provide a profound glimpse into the strength and genuineness of their faith. These trials are a powerful testimony to their commitment and courage. Throughout history, numerous Christians have faced unimaginable suffering, even enduring torture, dismemberment, and martyrdom, all because of their devotion to Christ. Their remarkable sacrifices inspire us and remind us of the immense cost of following Jesus. Yet, the trend of timidity displayed by the present-day Church, yielding to government overreach or even complying with laws that endorse sexual sin contrary to biblical teachings, will come at a significant cost.
It is high time for the Church to reclaim its boldness and restore the biblical understanding of masculinity and femininity. We must reject the watered-down version of Christianity that has spread throughout our culture and embrace a faith rooted in conviction and sacrifice. By understanding and embracing the unique roles and responsibilities of men and women as outlined in Scripture, we can restore clarity and purpose to our families, churches, and communities. Let us rise above the societal pressures, rekindle the fire of biblical truth, and stand firm in our commitment to Christ, no matter the cost.
As we progress, it becomes clear that the importance of strong, virtuous Catholic men is growing. This should not catch us off guard. The feminist movement of the 21st century is truly toxic. It goes way beyond advocating for the rightful appreciation of women; it seeks to establish female dominance. Moreover, its influence knows no boundaries. Like the LGBTQ community, its aim is to permeate every aspect of public, personal, and spiritual life. We must not only be alarmed by this trend but also prepare ourselves to stand firmly against it. We need biblically grounded shepherds and faithful women who can discern the subtle infiltration of an effeminate culture and guard against it.
Let us not forget that Catholicism is not egalitarian. While men and women are equally valued before the cross, our roles and responsibilities differ. In marriage, Christianity follows a complementarian model, where the husband leads with sacrificial love, and the wife respects and supports him. People are too sensitive about the word “patriarchy” nowadays. In terms of leadership, the Church holds a patriarchal stance. At the same time, patriarchy, like any other system, is not immune to the potential for sinful expressions. However, when approached with sacrificial love, adherence to biblical order, and a commitment to honoring God, the structure of patriarchy - as well as areas such as marriage, fatherhood, and heterosexuality - can yield to way more goodness. We should strive for a church culture that aligns with the gender-culture outlined in God’s Word: gentle, safe, and encouraging, while also strong, bold, and committed to upholding biblical order and fulfilling the mission entrusted to us. This balance allows the church to fully embody the presence of Christ, enabling His people to confidently advance alongside our great Lord.
We must prepare ourselves for an increasing need for men who embrace biblical masculinity and women who faithfully embody femininity. It is crucial not to overlook the pervasive influence of an effeminate culture and the agenda of distorted ideologies. By embracing the distinct roles and responsibilities that God has given to both men and women, we cultivate a church culture that mirrors the beauty of Christ and empowers His people to wholeheartedly pursue His mission with courage. We must recognize the urgency to embrace and embody biblical masculinity in the face of cultural challenges and shifting ideologies. Equipped with the truth of God's Word, we can navigate the complexities of the world and fulfill our God-given roles with great faith. Let us rise as men who boldly embrace our calling, standing firm in the face of challenges, and wholeheartedly pursuing lives of holiness and service to God and His Church. May we stand united, guided by His Word, and ready to face the battles ahead with strength, grace, and resolved faith.
From Nashville with love,

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.

2025-01-11 15:00:24收录的内容中 kind=1的部分,实话说 质量不高。 所以我增加了kind=30023 长文的article,但是更新的太少,多个relays 的服务器也没有多少长文。
所有搜索nostr如果需要产生价值,需要有高质量的文章和新闻。 而且现在有很多机器人的文章充满着浪费空间的作用,其他作用都用不上。
https://www.duozhutuan.com 目前放的是给搜索引擎提供搜索的原材料。没有做UI给人类浏览。所以看上去是粗糙的。 我并没有打算去做一个发microblog的 web客户端,那类的客户端太多了。
我觉得nostr社区需要解决的还是应用。如果仅仅是microblog 感觉有点够呛
幸运的是npub.pro 建站这样的,我觉得有点意思。
yakihonne 智能widget 也有意思
我做的TaskQ5 我自己在用了。分布式的任务系统,也挺好的。

@ d61f3bc5:0da6ef4a
2025-05-06 01:37:28I remember the first gathering of Nostr devs two years ago in Costa Rica. We were all psyched because Nostr appeared to solve the problem of self-sovereign online identity and decentralized publishing. The protocol seemed well-suited for textual content, but it wasn't really designed to handle binary files, like images or video.
The Problem
When I publish a note that contains an image link, the note itself is resilient thanks to Nostr, but if the hosting service disappears or takes my image down, my note will be broken forever. We need a way to publish binary data without relying on a single hosting provider.
We were discussing how there really was no reliable solution to this problem even outside of Nostr. Peer-to-peer attempts like IPFS simply didn't work; they were hopelessly slow and unreliable in practice. Torrents worked for popular files like movies, but couldn't be relied on for general file hosting.
Awesome Blossom
A year later, I attended the Sovereign Engineering demo day in Madeira, organized by Pablo and Gigi. Many projects were presented over a three hour demo session that day, but one really stood out for me.
Introduced by hzrd149 and Stu Bowman, Blossom blew my mind because it showed how we can solve complex problems easily by simply relying on the fact that Nostr exists. Having an open user directory, with the corresponding social graph and web of trust is an incredible building block.
Since we can easily look up any user on Nostr and read their profile metadata, we can just get them to simply tell us where their files are stored. This, combined with hash-based addressing (borrowed from IPFS), is all we need to solve our problem.
How Blossom Works
The Blossom protocol (Blobs Stored Simply on Mediaservers) is formally defined in a series of BUDs (Blossom Upgrade Documents). Yes, Blossom is the most well-branded protocol in the history of protocols. Feel free to refer to the spec for details, but I will provide a high level explanation here.
The main idea behind Blossom can be summarized in three points:
- Users specify which media server(s) they use via their public Blossom settings published on Nostr;
- All files are uniquely addressable via hashes;
- If an app fails to load a file from the original URL, it simply goes to get it from the server(s) specified in the user's Blossom settings.
Just like Nostr itself, the Blossom protocol is dead-simple and it works!
Let's use this image as an example:
If you look at the URL for this image, you will notice that it looks like this:
blossom.primal.net/c1aa63f983a44185d039092912bfb7f33adcf63ed3cae371ebe6905da5f688d0.jpg
All Blossom URLs follow this format:
[server]/[file-hash].[extension]
The file hash is important because it uniquely identifies the file in question. Apps can use it to verify that the file they received is exactly the file they requested. It also gives us the ability to reliably get the same file from a different server.
Nostr users declare which media server(s) they use by publishing their Blossom settings. If I store my files on Server A, and they get removed, I can simply upload them to Server B, update my public Blossom settings, and all Blossom-capable apps will be able to find them at the new location. All my existing notes will continue to display media content without any issues.
Blossom Mirroring
Let's face it, re-uploading files to another server after they got removed from the original server is not the best user experience. Most people wouldn't have the backups of all the files, and/or the desire to do this work.
This is where Blossom's mirroring feature comes handy. In addition to the primary media server, a Blossom user can set one one or more mirror servers. Under this setup, every time a file is uploaded to the primary server the Nostr app issues a mirror request to the primary server, directing it to copy the file to all the specified mirrors. This way there is always a copy of all content on multiple servers and in case the primary becomes unavailable, Blossom-capable apps will automatically start loading from the mirror.
Mirrors are really easy to setup (you can do it in two clicks in Primal) and this arrangement ensures robust media handling without any central points of failure. Note that you can use professional media hosting services side by side with self-hosted backup servers that anyone can run at home.
Using Blossom Within Primal
Blossom is natively integrated into the entire Primal stack and enabled by default. If you are using Primal 2.2 or later, you don't need to do anything to enable Blossom, all your media uploads are blossoming already.
To enhance user privacy, all Primal apps use the "/media" endpoint per BUD-05, which strips all metadata from uploaded files before they are saved and optionally mirrored to other Blossom servers, per user settings. You can use any Blossom server as your primary media server in Primal, as well as setup any number of mirrors:
## Conclusion
For such a simple protocol, Blossom gives us three major benefits:
- Verifiable authenticity. All Nostr notes are always signed by the note author. With Blossom, the signed note includes a unique hash for each referenced media file, making it impossible to falsify.
- File hosting redundancy. Having multiple live copies of referenced media files (via Blossom mirroring) greatly increases the resiliency of media content published on Nostr.
- Censorship resistance. Blossom enables us to seamlessly switch media hosting providers in case of censorship.
Thanks for reading; and enjoy! 🌸

2025-05-06 01:06:54เมื่อวานนี้เรารู้เรื่อง Meat Free Monday ของท่านเซอร์พอลกันแล้ว วันนี้เรามาต่อเนื่องกับแสงสีกันอีกนิดครับ
Anne Hathaway กับ The EVERY Company จากเจ้าหญิง The Princess Diaries สู่ราชินีโปรตีนไร้ไก่ ในยุคที่ความเปลี่ยนแปลงไม่เคาะประตู แต่มาถีบประตูบ้านเข้าใส่เลย บรรดาเซเล็บฮอลลีวูดก็ไม่ได้อยู่เฉยๆ แค่ใส่กระโปรงขึ้นพรมแดงหรือไปเล่นหนังรางวัลเท่านั้น แต่บางคน เช่น Anne Hathaway ก้าวเข้ามาอยู่เบื้องหลังระบบอาหารโลกในรูปแบบที่เงียบ…แต่เขย่าพื้นโลกได้เหมือนกัน
ใช่จ้ะ... Anne Hathaway คนเดียวกับที่เฮียเคยเห็นใน The Devil Wears Prada หรือเจ้าหญิง Mia ใน Princess Diaries ได้ลงทุนแบบเอาจริงกับบริษัทเทคโนโลยีอาหารสุดล้ำที่ชื่อว่า The EVERY Company ซึ่งพัฒนาโปรตีนจากไข่ที่ไม่ใช้ไก่ ไม่ต้องมีฟาร์ม ไม่ต้องฟัก และไม่ต้องฟูมฟักศีลธรรมให้สั่นไหวด้วยการฆ่าสัตว์เลยแม้แต่นิดเดียว
ทบทวนกันจากสัปดาห์ที่แล้วครับ The EVERY Company เดิมชื่อ Clara Foods ก่อตั้งในกลางยุค 2010s ณ ใจกลางซิลิคอนวัลเลย์ แหล่งรวมจินตนาการและเงิน VC ที่ไม่รู้จะเอาไปลงกับอะไรดี บริษัทนี้ไม่ได้เลี้ยงไก่ ไม่ได้ใช้ถาดไข่ แต่ใช้ “Precision Fermentation” ซึ่งก็คือการเอา DNA ที่เป็นรหัสของไข่ขาว (Ovalbumin) ไปใส่ในจุลินทรีย์สายพันธุ์เฉพาะ แล้วเลี้ยงด้วยน้ำตาลในถังหมัก สุดท้ายมันก็ผลิตโปรตีนออกมาที่มีโครงสร้าง “เหมือนของจริงเป๊ะ”
มันคือการทำไข่จาก “ยีสต์” ไม่ใช่จาก “แม่ไก่”
การลงทุนของ Anne ครั้งนี้ ถือเป็น B2B investment ครั้งแรกในชีวิต และดูจะไม่ใช่แค่ลงทุนแบบเซ็นเช็คเฉยๆ แล้วไปจิบไวน์ที่คานส์นะ เพราะเธอให้สัมภาษณ์ว่า
“It’s clear that our food system needs a change. EVERY is one part of a beautiful future.” (มันชัดเจนว่าระบบอาหารเราต้องเปลี่ยนแปลง EVERY คือส่วนหนึ่งของอนาคตที่งดงามนั้น)
แม้ไม่มีการเปิดเผยจำนวนเงินหรือสัดส่วนหุ้นอย่างเป็นทางการ แต่สื่ออุตสาหกรรมอาหารอย่าง Food Navigator USA ก็ชี้ว่า เธอเป็นอีกแรงที่ช่วยดันชื่อเสียงของบริษัทให้ “กลายเป็นไวรัล” ในหมู่นักลงทุน และอาจเปิดประตูสู่การยอมรับของตลาดผู้บริโภคได้ในวงกว้าง
The EVERY Company ไม่ได้หวังจะแค่ขาย “ไข่” ในซูเปอร์มาร์เก็ตแบบธรรมดาๆ แต่เริ่ม “แทรกซึม” จากเบื้องหลังในอุตสาหกรรมอาหารอย่างแยบยล จะเปลี่ยนระบบอาหารโดยใช้แนวทาง “B2B only” คือผลิตขายให้เชฟ ร้านอาหาร และโรงงานเท่านั้น (ยังไม่วางจำหน่ายปลีกทั่วไป เพราะบางตัวอย่าง EVERY Egg ยังรอรับรอง GRAS จาก FDA)
เคยมีการร่วมงานกับเชฟมิชลิน Dominique Crenn จากร้าน Atelier Crenn ในนครซานฟรานซิสโก ซึ่งเธอยืนยันว่า EVERY Egg เป็นตัวเปลี่ยนเกม ที่ทำให้เธอสามารถสร้างเมนูใหม่ที่ “ไร้สัตว์” ได้โดยไม่เสียความสร้างสรรค์หรือรสชาติ
แม้ Anne จะไม่มีตำแหน่งในบอร์ดบริหาร แต่การที่เธอลงทุนใน The EVERY Company ทำให้หลายองค์กรจับตามอง และส่งผลต่อภาพลักษณ์ของ “โปรตีนสังเคราะห์จากจุลินทรีย์” ให้ดูหรู ดูสะอาด และเหมาะกับสายสุขภาพ-มังสวิรัติ ทั้งที่จริงๆ แล้ว มันคือ “ผลิตภัณฑ์โรงงานที่ผ่านกระบวนการขั้นสูงมาก”
The EVERY Company ยังได้รับเงินลงทุนจากกลุ่มใหญ่อย่าง Temasek (กองทุนจากสิงคโปร์) และ Prosperity7 Ventures ที่เป็นแขนของ Saudi Aramco ซึ่งก็เป็นอีกประเด็นน่าคิด…ว่าพลังทุนที่อยู่เบื้องหลัง “ไข่ไม่ใช้ไก่” นี้ มาจากหลายทิศหลายทาง ทั้ง Silicon Valley, ตะวันออกกลาง และ Hollywood
การที่ Anne Hathaway ลงทุนใน EVERY ไม่ใช่เรื่องผิด แต่เป็นหมุดหมายที่น่าสนใจในยุคที่ “อาหาร” ไม่ใช่แค่เรื่องอิ่มท้อง แต่กลายเป็นการเมือง วิทยาศาสตร์ เศรษฐกิจ และการสร้างภาพลักษณ์ของคนดังในคราวเดียวกัน
ไข่ที่ไม่มีไก่ โปรตีนที่ไม่มีฟาร์ม…ดูเหมือนจะสวยงาม แต่ถ้าเรามองให้ลึก บางครั้งอาหารก็อาจไม่ใช่เรื่อง “ของกิน” อย่างเดียวอีกต่อไป
เรื่องบางเรื่อง คนในบางสังคม คนในบางกลุ่มเท่านั้น ที่จะมีโอกาสเลือกก่อน กี่ครั้งต่อกี่ครั้ง ก็แบบนี้ครับ #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

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.
