built ecashmesh for the @bitshala_org BOSS hackathon. connecting @fedimint federations & @CashuBTC mints through @lightning It also checks whether a source can actually afford the route before recommending it. Ecash that isn't stuck on an island.

We found a bug in our Lightning gateway's LNv2 payment handling and are contacting public gateway operators. User funds, federations, and ecash are not affected. This is separate from the issue fixed in v0.12.1. Gateways on v0.11 are not affected.

We're also releasing v0.11.4 with gateway hardening we found along the way. v0.11 gateways are not affected by the bug above, so there's no rush: update at your convenience.

The bug came from our protection against paying the same invoice twice, which ran too late in the payment flow. We continue to do our own AI-accelerated security research and appreciate external research findings at [email protected]

Federate all the ecash! πŸš€
The FROST basis for this new design enables composability across the ecosystem, with @bitcoindevkit to power onchain, and Bark (@secondhq) to power the Lightning! @callebtc @btcplusplus

Just caught @joschisanbtc’s talk in BTC++ Berlin on @fedimint and am blown away. As someone who is ecash-agnostic I don’t think there’s another project in bitcoin that’s using as much cutting edge black magic tech in pursuit of their goals. Incredibly impressed.

Today at @btcplusplus @joschisanbtc explained all the engineering that went into Fedimint over the last years 😎 Missed it? Watch out for the recordings!

Had a great time at Ecash Hackday in Berlin, got a Fedimint running with 3 different implementations by @thesimplekid, me and the Fedimint team! πŸš€ Already got 3 Fedimint implementations now, who will build the 4th one? 😏
Why multiple implementations make sense for security beyond a certain point:

Fedimint now has a native Android SDK πŸŽ‰ org.fedimint:sdk 0.1.0-beta.1 is live on Maven Central, the first native Android SDK for Fedimint. Join a federation, send and receive ecash, and pay over Lightning, all from Kotlin, in one dependency. central.sonatype.com/artifac… @fedimint

Multiple Fedimint implementations were part of the original vision, now with the help of AI the dream is becoming reality πŸ₯Ή Time to call the fedimint repo minimint again? Has my holding out finally paid off? 😝

We found a bug in our legacy Lightning integration and are contacting public gateway operators. User funds, federations, and ecash are not affected. Gateways using LDK Node or our newer LNv2 protocol are also not affected. We still recommend staying up to date. 🧡

If we haven’t reached out, please update to v0.12.1 ASAP, or shut down your Lightning gateway in the meantime if that’s not feasible. Users of federations without an active Lightning gateway will still be able to make ecash and on-chain transactions. github.com/fedimint/fedimint…

The bug results from an interaction between misunderstood HTLC interception behavior and our LN-ecash swap validation logic that evaded previous scans. We continue to do our own AI-accelerated security research and appreciate external research findings at [email protected]

Why multiple implementations make sense for security beyond a certain point:
Calling on fellow cypherpunks to build alternative Fedimint implementations. The Liquid hack shows once again that single points of failure are what will break our systems and that includes the code we write. Security is an asymmetric game: an attacker has to find one weakness, while defenders have to find all. AI has permanently changed the attacker-defender balance for the worse. This is a fundamental problem for the entire freedom tech space and only mitigatable by aggressively reducing single points of failure. Federations are meant to do exactly that, but just like Liquid, Fedimint shares the β€œsingle implementation” problem. If we still want to bring privacy and freedom to the world we need to work together more than ever to reduce these single points of failure. For me that means seeking help to bootstrap independent Fedimint implementations. We are still early, but I've started extracting a specification that others could build off and would love to collaborate with any fellow cypherpunks who want to join us in that mission. In particular, I’d love to work with @callebtc and the @CashuBTC team, who have much more experience with a multi-implementation ecash protocol while the Fedimint team brings federation experience to the table. While AI exposes existing vulnerabilities and wreaks havoc in our ecosystem, it is also an opportunity for talented engineers to be far more productive than ever before. I’ve been talking with @fedibtc and there is funding for a small, crack team to pull this off. If this sounds interesting as a funder, please reach out! The idea is for the teams to be purposefully disconnected from the existing Fedimint implementation and to work autonomously, communicating mainly through the spec process. If you too believe that privacy and freedom are needed more than ever, please join us!

Using @fedibtc and a self-hosted @fedimint federation to make Bitcoin everyday money! This is Good Hope federation, running on 7 @start9labs devices, spread out across the Western Cape province of South Africa. We use it every day. But it's still mind blowing. Every single time.
