    Q2 was Blockstream moving from research to release. @blksresearch took post-quantum Bitcoin from a live deployment on @Liquid_BTC to OP_CHECKSHRINCS, a signature opcode the whole network can evaluate. @BlockstreamJade became a three-model lineup, with the new Jade Core turning

    Simplicity's site just got a full redesign. Simplicity lets you prove exactly how a contract behaves before it goes live. No surprise fees, no transactions failing mid-execution. The security guarantees are part of the language, not bolted on after. Live on @Liquid_BTC mainnet,

    The DahLIAS Eurocrypt talk by @real_or_random is online now! It focuses on what it takes to deploy signature aggregation in Bitcoin: pitfalls, attacks, and practical requirements. DahLIAS is not post-quantum, but many of these issues matter for PQ aggregate sigs too. 👇

    Excited to share that our DahLIAS paper has been accepted to Eurocrypt 2026! 🎉 DahLIAS enables cross-input signature aggregation (CISA) on Bitcoin’s secp256k1 curve. See you in Rome, May 10–14! Thanks to @yannickseurin (@Ledger), @real_or_random & @n1ckler (@blksresearch)!

    The @blksresearch team has spent over a year on quantum research. @adam3us on OP_CHECKSHRINCS, a Bitcoin-optimised version of the NIST standard, an opt-in way to be quantum-ready without paying the cost of big signatures today.

    When big money moves, "probably correct" isn't good enough. Simplicity lets you deploy formally verified Bitcoin contracts that do exactly what they should, proven before deployment.

    Build lending contracts you can formally verify with Simplicity, alongside the banking teams at Swisscom and Luzerner Kantonalbank. We cover where core banking is heading and how Liquid fits, then write them together on @Liquid_BTC. Zürich, July 2 🇨🇭 lu.ma/h94asyi8

    Stateful signatures trade systemic risk for localized risk. The failure mode is confined to individual wallets, not the network. @n1ckler at @TheBitcoinConf 2026 on why that's the better trade-off to explore.

    Bitcoin started as a discovery, not an invention. @adam3us explains why on @BitcoinSuisseAG, plus the post-quantum migration and how @blksresearch is preparing Bitcoin for it with OP_CHECKSHRINCS.
