The Blockstream Explorer API is home to one of the fastest ways to sync a Bitcoin wallet. With QuickSync, you send one descriptor and get the complete history back in a single response. Grab an API key and see it for yourself. 🔗 dashboard.blockstream.info/

Bitcoin's neutrality is its edge. @adam3us on why a decentralized asset with no company in control wins: rivals won't build on each other's chains, but everyone can build on Bitcoin.

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 self-custody into a five-minute move off an exchange. Liquid published a roadmap that puts 0-conf and a trust-minimized bridge on the calendar. @Core_LN strengthened node architecture with bwatch, while the Explorer API kept blockchain data fast and dependable at enterprise scale. Blockstream's Q2 2026 Quarterly Update is live. blog.blockstream.com/blockst…

Blockstream Quarterly Update - Q2 2026

From a proposed post-quantum opcode to a reimagined Jade lineup and a Liquid roadmap with dates, here's what Blockstream shipped in Q2 2026.

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, running real financial contracts, and built for the developers and institutions building high-assurance Bitcoin applications. blog.blockstream.com/welcome…

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.

After 7 years, Blockstream Research Director @n1ckler is stepping back as a libsecp256k1 maintainer, leaving the library in the strong hands of its other long-time maintainers. @blksresearch remains a key contributor. Learn more about this cryptographic library that secures every Bitcoin and @Liquid_BTC transaction. ⬇️

libsecp256k1 is the cryptographic library that secures every Bitcoin transaction and @blksresearch is one of its key contributors and maintainers. They also maintain libsecp256k1-zkp, the extended fork that powers @Liquid_BTC's Confidential Transactions, MuSig2, and zero-knowledge proofs. The team has just brought the zkp fork up to date with 2.5 years of upstream improvements.

The work continues, @blksresearch with @n1ckler at the helm recently proposed OP_CHECKSHRINCS, a hash-based signature opcode for post-quantum Bitcoin. blog.blockstream.com/op_chec…

OP_CHECKSHRINCS: A Hash-Based Signature Opcode for Post-Quantum Bitcoin

OP_CHECKSHRINCS is a proposed Bitcoin opcode for post-quantum signatures whose security rests on SHA-256, the hash function Bitcoin already uses.
