Learn about Bitcoin for your lifestyle, enjoying volatility and thriving in uncertainty. My goal is tech + hacking => liberty and life satisfaction. Find my books and courses. Books (EN,ES): amazon.com/author/bednar Books, Courses (EN, ES): hackyourself.io/shop/ Books, Courses (SK): juraj.bednar.io/shop/ I teach how to handle volatility, what to do when you want to enjoy the value of your Bitcoin, how Lightning network works, cypherpunk tech and more, hacking applied to many areas of life, etc.

@callebtc It's more complicated... Yes, you have to register your identity. But the newspaper won't identify you. I looked at the source code. The bigger problem - you will need an id and you will need approved phone to pass attestation. juraj.bednar.io/en/blog-en/202…

Age verification is the Trojan horse for complete control of the internet. Imagine you'd have to register your identity to read a newspaper. That's what this is about. They say it's for the children, but it really is about taking away your right to use the web anonymously.

@mynymbox Yes. But this is the other way around - it uses cashu mints to accept lightning payments. The customer sees a lightning invoice.

@jurbed If you run a BTCPayServer there is also a nice plugin for Cashu

Privacy isn't just for customers; it's for merchants too. Why should your payment processor know your turnover, your products, or your customer's identity? CashuPayServer uses Cashu mints for settlement of Lightning payments. This creates a "privacy buffer" between your shop and the network. The mint sees the Lightning payment; you see the credit. Nobody sees the link between the two except you. Why Cashu mint? The easiest way to accept Lightning and not run a Lightning node. And yes, it can immediately withdraw to a real non-custodial Lightning wallet. Accept Lightning with "Stealth Mode" enabled. cashupayserver.org

For most of human history, the bread problem was solved by money. You hand the baker coins, the baker hands you bread, neither of you needs to know the other's name. Reputation only became necessary once we introduced asynchrony and reversibility: credit, chargebacks, pay-later. The seller has to bet on who you are instead of what you paid, and that bet is what accounts, KYC, fraud scoring, and social graphs are pricing. Identity theatre is unpriced credit risk in a uniform. Cashu and Routstr collapse that detour. Bearer ecash for an LLM call is structurally identical to coins for bread. Settled on the spot, no counterparty bet, no recourse needed because there's nothing to recover. We didn't invent anything. We walked back to where we started after a few centuries of building ledgers, banks, and identity systems to patch the holes in deferred payment. Money → identity theatre → money. The cypherpunk point here is boring: finality is cheaper than verification.

@marttimalmi Beautiful, also repost on Nostr please :) I've tried downloading the release, but I'm getting "File request failed: Timeout waiting for client response" on Firefox when trying to download release binary.

DaisyDisk is great, but SquirrelDisk is free, and works on mac, linux and windows. Made some performance and UX improvements. Source and binaries: git.iris.to/#/npub1xdhnr9m…

@Posledniskaut Zaujímavé sú demonštrované preferencie, nie sny.

Odchod ze Slovenska zvažuje nebo plánuje 75 procent mladých ve věku 16 až 17 let, ukázal průzkum Úřadu komisaře pro děti. S určitostí chce jít do zahraničí přes 38 % dotázaných. Z těch, kdo uvažují o odchodu, se až 42 procent neplánuje vrátit.

Cashu is powering far more than just Bitcoin wallets. While most people think of standard user-facing Bitcoin wallets when they hear Cashu, there’s a whole separate economy emerging around machine-to-machine payments. One of the best examples is Routstr, an open-source decentralized marketplace for AI inference. Routstr uses Nostr and Cashu at its core. Providers offer AI inference, and users pay for AI with Bitcoin. You can use Routstr as a normal AI chat interface or as a provider for your own AI agent. It gives users access to hundreds of models, similar to OpenRouter, but paid in Bitcoin with strong privacy for the payments attached to your AI chats. There are no accounts. To fund your balance, you pay a Lightning invoice and mint Cashu ecash. Every time you make a query, you attach ecash to the request itself as a bearer token and micropayment for that individual call. Now here’s the cool part. Anyone can become a provider because Nostr is an open network. Anyone can become an ecash mint because of how easy it is to run a Cashu mint. And every Routstr user has full control over which providers and which mint they choose. I think Routstr is a great example of what becomes possible with a micropayment system like Cashu on Bitcoin. It removes much of the friction involved in building apps that use payments, because you don’t need to create user accounts, build a ledger, or track users at the expense of their privacy.

@jan_21m Roger ver sa vzdal občianstva a income mal osobný. Každopádne on tie občianstva neriešil ani kvôli daniam. On chcel proste vypadnúť.

@jurbed No, s dnešním marketingem od "passport bros" bych se tomu upřímně moc nedivil. A těch případů týkajících se Američanů také není málo, viz Roger Ver. I když je možné, že tam to nebyla nevědomost ale zkusil to schválně.

Hacky a dobré setupy fungují často velmi dobře jen do doby, než je o ně velký zájem a používá je více lidí. 📈 Poptávka po karibských občanstvích je ohromná a 50 % jsou žadatelé z US, kteří možná netuší, že je na ně uvalena citizenship tax (čistě moje domněnka). Karibik už ale není to, co býval... Dalším skvělým příkladem jsou anonymní nonKYC krypto karty. 💳 🇵🇾 A nebo žádosti o paraguayské rezidence, které za poslední rok narostly o 85 % ! 🎙️ Další díl se @stalliondelsur PLAN B brzy. #planb

@stalliondelsur @jan_21m Klavesnicovi teoretici určite, pochybujem že niekto dá štvrť mega za citizenship by investment lebo to nepochopil...

@jurbed @jan_21m Presne. Problem je ze hodne lidi plácají dohromady daně a globální mobilitu. Hodí na jednu hromadu rezidenci, daňový domicil, občanství a mezi to dají rovnítko.

@jan_21m Hej, veď on to tam má zle. Predpokladať že ľudia čo dajú 250k za citizenship by investment nevedia ako to funguje je podľa mňa úplne mimo.

@jurbed Ano, reagoval jsem spíše na The Way of Jerz.

@Dimitris Yes. But reserves usually need bond as collateral, so this changes when the loan is sent out of the bank, because the net difference is usually settled in the reserve.

@jurbed > Each usdc held on Base or elsewhere is financing American government. That is an interesting observation because each $ or € at the bank is mostly financing retail and corporate loans. Tether and GENIUS-Act stablecoins mostly finance the US government.

It seems super funny how corpos are trying to push stablecoin agentic payments with complicated schemes. Writing payments for every api call into blockchain, even the corporate one, is super expensive. So they make super complicated facilitators which would make it possible. It's basically prepayment to a third party. We have @CashuBTC. Just include the token in request headers and get change if needed. No back and forth required. The API can claim the payment immediately on the mint. Even if you consider the threat model the same (mint=facilitator), the protocol is much more elegant. And even getting Cashu tokens can be done over lightning, so lower exposure and still no on chain fees or waiting. I think the problem is that people are scared of sats as the unit. Originally I thought it's custody risk (and I mean mainly regulatory risk), but facilitators are custodians. I think it's just cultural. And Coinbase / Circle pushing their product. Economic implications: Each usdc held on Base or elsewhere is financing American government. And each Base transaction helps the pnl of Coinbase. Each sat held and used helps the parallel way. I made my choice. Better tech, better privacy and no financing of monopolies on violence. That's why my agent has a Cashu wallet. And I'd gladly finance good mints with some fees.

What if the EU built GitHub?

@sabrinaesaquino @AskVenice That my agent did. But it does not look very good. I'll try with a different photo maybe.

@jurbed @AskVenice You need to send the audio file with the audio_url parameter to Wan 2.7. Also works with Seedance 2.0 but they are very moderated when it comes to human faces

The characters in Tamers of Entropy don't fill out forms or ask permission. They build parallel paths and treat barriers as information about where to dig next. So I gave the main ones their own Nostr keypairs. They're posting now, before you've read the book — comments, observations, fragments of how they see the world. Right now it looks like random strangers talking. Once you finish reading the story it becomes something else: a continuation that doesn't stop at the last page. You don't need an account to watch them. Go to tamersofentropy.net/nostr and see what they say. The longer piece I published explores why we did it this way — how names freeze us in time, why continuous identity can be a trap, and how simple it is to create new ones when you want to experiment with who you are. primal.net/a/naddr1qvzqqq…

@xm_build @sabrinaesaquino You can use OpenAI models and tools through Venice.

@sabrinaesaquino hermes and venice are solid for prototyping, but what’s your plan for when openai releases similar tools with better dev experience?
