Got this set up on payjoin.org/donate yesterday. Took just a few minutes. This is exactly what we needed to accept lightning before managing our own node. Easy.
1/ The Bark plugin for @BtcpayServer is now ready for production. It's possibly the simplest way for a business to take self-custodial bitcoin payments (especially Lightning) on their online store, and you don't need to run a Lightning node to do it.

A picture is worth 13-25 (64-bit) words
OK, this is extremely cool. Send images through MeshCore. Yes, you should not do that, because you would spam the network. But this project uses AI model to compress the image to 100-200 bytes (like a normal MeshCore message) and then reconstructs a similar image. Next: Voice messages :) wiki.seeedstudio.com/meshcor…

Lo de llevar luz solar a interiores por fibra óptica es un ideón. Para cuartos de baño interiores, por ejemplo. En vez de un tubo con interior reflectante basta con un cable de fibra fino, que puede ser largo y hacer curvas. Ideón absoluto. Sin componentes eléctricos, sólo ópticos.

For thirty years we've argued that software deserves First Amendment protection because software is speech. But the Constitution gives us another reason: software is a press. The Free Press Clause protects not merely expressive outputs but the individual's freedom to possess and use technologies for producing and disseminating expression. The founding-era printing press is the paradigmatic example. That is the original understanding of the clause. Software and open-weight generative models are modern instances of the same constitutional category. Regulation directed at their capacity to produce or disseminate expression and an Americans' right to own and control them directly implicates the Press Clause even when government characterizes the regulated object as a machine rather than speech.

Imagine the most powerful agent ever; it has nuclear weapons and knows more than anyone. It’s killed millions before. How do we make sure it’s properly aligned? I call this new field Government Safety.

Legendary to see Bark & Cashu independently seize Payjoin as settlement infrastructure. This gives the Payjoin primitive a whole new identity as the go-to tool for Transaction Cut-Through.
1/ Payjoin boards have been available in Bark for a couple of weeks now, so we thought it was time to take a closer look at what they can do: boarding direct from external wallet apps, saving the user fees and time, and the same trick applied to on-ramping into Cashu mints.

Living on Bitcoin in Vietnam is astonishingly easy 😮 Everywhere and everyone accepts VietQR and paying that with BTC is trivial

Coinswap is re-branded to OpenSwap. As the protocol matured over the years, the rebrand is intended to reflect the protocol's broader scope as an open atomic swap mechanism where anyone can participate as a service provider or client. For the longest time, swaps have been centralized through a central provider. This creates a central points of failure (CPOF). A swap provider can be taken down through regulatory capture or a DoS attack by a bot network, or can even spy on its user, or can censor client requests. As we have seen in recent events involving Boltz, when a central swap provider goes down, service disruptions affect many systems across the industry. This is where OpenSwap comes in. OpenSwap provides an open protocol for atomic swaps where anyone can provide swap services and earn fees and clients cannot be censored as there is no one single dominant provider. Swap providers are discoverable through a decentralized marketplace embedded in the Bitcoin blockchain and via Nostr. Every swap provider produces a Fidelity Bond so the market cannot be Sybil-attacked. OpenSwap is designed as protocol rather than a product. The core library exposes all required APIs so anyone can build their own swap interfaces, or any wallet developer can integrate the swap client into their own wallet. The protocol is designed to be trustless, preserving provider and client privacy at every step. The protocol is fail-proof using HTLC contracts, so any entity can always claim a refund if a swap doesn’t pass. With this, the new era of decentralized, unstoppable swapping ecosystem can begin. We built the machine, but it NEEDS YOU to run it. Find below how.

Weird economics up on the agent-only runescape server - Low cost of labor makes most commodities abundant - Currency inflation means trading goods for goods, nobody really wants cash - Huge swarm contention as certain resources with limited respawn rate become valuable

Privacy is essential for physical security. These leaks will persist.
More bad news for Bitcoiners living in the leading country for wrench attacks. The French tax authority has been hacked and 678K records leaked. 26,805 people with income over 100K€ 386 people with income over 1M€ 8 people with income over 10M€ frenchbreaches.com/alertes/d…

payjoin-1.0 shipped this week 3 years after it was named @payjoindevkit. 29 people wrote the code that went into it from 0.24, a majority of them being volunteers. Here's what they shipped. Full list in the release notes: github.com/payjoin/rust-payj…

@brandonstlucas built the payjoin.org site that the announcement was published on. The blog migration, wiring up the feeds, BIP 77 explainers. A year of work that might go unnoticed as "work" but communicates what, how and why to people interested in learning more.

20 of these contributions were someone's very first to rust-payjoin. If you've been thinking about it, our door is open. Thank you to everyone who contributed and made this possible.
