Honoured to present Sowellian Governance and discuss decentralized communities with the Bitcoin Community in Athens Come join us on May 14th meetup.com/blockchaingree…

@marcmynome Well, most stablecoins either allow for your wallet to be frozen or they have confiscatable collateral or both. So the peer-to-peer part on its own is only partly valuable.

Stablecoins? "A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution"

I've thought a lot about this, and I think its worth understanding WHY it's disrespectful jfdi.bot/blog/ai-genera…

@LeonWaidmann Given ETH/BTC is down over -60% since then, it shows that with fewer coins coming into circulation, there is still considerably less demand. Perhaps NOT fiddling with the knobs and dials was the entire point, not the inflation rate magnitude. Thanks for coming to my TED talk.

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

@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.

I don’t think it’s an exaggeration to call this the greatest piece of prediction market content created to date.

@LukeDashjr I love Dr Pepper and now that it is finally available where I live, I am not having any because I switched to water. It turned out I did not need the sweet drinks I was having daily with food.

I quit Dr. Pepper a few weeks ago, to reduce my sugar levels. But the alternatives I've tried (Zevia and Liquid Death) taste terrible. Any real solutions? 😕 (Dr Pepper Diet and Zero have aspartame, which is apparently poison)

The Year 2026 – Shopping Without Browsing: I wanted to make a cup of coffee today. The coffee maker displayed a message indicating it needed cleaning and asked me to insert a cleaning disc and a tablet into the lever. I couldn't find the cleaning disc (see attachment). I opened Signal and sent the attached photo to my Signal AI with the following message: /ai Find out what this cleaning filter is called, where it's cheapest in Slovakia/Czech Republic, and order 2 pieces right away for our company (Nethemba s.r.o.). Use my card in my name for payment, card number XYZ (I provided it with a one-time Revolut card). If it requires two-factor authentication, let me know. Five minutes later, I received an email notification that the order and payment for 2 Sage cleaning discs, 53/54, had been successfully completed (see attachment). Everything went flawlessly, on the first try! AI Agent: 1. Identified the exact type of cleaning filter from the photo. 2. Found out where in Slovakia/the Czech Republic it was available at the lowest price. 3. Looked up our company's billing information. 4. Analyzed what the order and registration forms for that e-shop looked like. 5. Completely filled them out, including all necessary information. 6. Paid and ordered the goods. I didn't open a web browser the entire time! Using a browser to place orders is starting to feel pretty obsolete :-) I just sent one message on Signal. Technical background—if you want to set up a magic agent that will do almost everything for you: My Signal bot processed my message via signal-cli and forwarded it through my Signal-Hermes bridge to my Hermes agent. The Hermes agent runs on its own server and, via my Venice.AI API, is connected to Claude Sonnet 4.6 (a commercial, low-cost model) or Kimi 2.6 with a fallback to GLM 5.1 / Gwen 3.6 Plus (these are currently the best open-source LLM models). Security: 1. Commercial models (GPT, OPUS, Sonnet) will normally refuse to accept and use a credit card number (everything is logged, and it really isn't a good idea). You should therefore use open-source models (Gwen 3.6 Plus is even uncensored and easy to set up). 2. You can run open-source models entirely on your own machine or server and completely avoid using third parties (Gwen 3.6, Gemma 4, and GLM 5.1 work without issues—if you have a powerful GPU; as for Kimi 2.6, forget about it—it requires 2 TB of disk space and 500 GB of RAM). 3. If you don't have your own server, you can also run the Hermes agent on your desktop. However, if you want your agent to work nonstop, you must keep it running nonstop (for example, my Hermes agent analyzes current changes in offshore legislation worldwide and sends me a summary email every morning). 4. If you don't have the hardware for this, you can use services like Venice.AI or Routstr.com. Many open-source models can be run with end-to-end encryption (TEE-E2EE), so the service provider (Venice.AI) cannot access your data (!) You don't need to run them on your own machine. 5. For payments, use single-use Revolut cards or virtual Revolut cards with a defined transaction limit or monthly limit, thereby completely minimizing the risk of misuse. Don’t do things that AI can already do for you.

@TheBitcoinLayer @ChrisMasterjohn I am curious about the image of Saint Porphyrios, inscribed in Greek, sitting on the shelf.

#GLP1 drugs (#Ozempic, #Wegovy, etc.) were supposed to be about weight loss and diabetes. They’re turning into something much bigger. Here's a thread about what I've learned reporting this story for @nytopinion for over a year: nytimes.com/interactive/20…

🚨 BREAKING: The FBI has successfully extracted deleted Signal messages from a suspect's iPhone via notification storage, the place where all your notifications are stored for up to one month. Notification storage stores data from all messaging apps, it's a big flaw in iOS. But there's a way to turn it off...

I beg everyone in crypto to read this in full. I expected this to be another case of social engineering, likely some recruiter/job offer shit. I was very wrong. And the depth of the operation and personas makes me think they already have multiple other teams on lock. 😳

There is also a strategic opportunity that Europe has yet to fully grasp. Russia's strength depends heavily on its human capital. Creating structured pathways for highly skilled Russians — engineers, programmers, technical specialists — to relocate to Europe would strengthen European economies and weaken the Kremlin's long-term capacity.
