Announcing DahLIAS! 🎉 The first crypto protocol for full cross-input signature aggregation that allows reusing Bitcoin's curve secp256k1. ✅ 64B sigs ✅ Verify is ~2x faster than half-agg'd Schnorr sigs ✅ 2-round signing Kudos to the team: @real_or_random @yannickseurin! 👇
Join the forefront of Bitcoin innovation! Blockstream Research seeks an Applied Cryptographer focused on Post-Quantum Crypto. Contribute to long-term security and impactful research.
Summary of Boston Bitdevs:
Sebastian Falbesoner (@theStack), Jonas Nick (@n1ckler), and Tim Ruffing (@real_or_random) posted to the Bitcoin-Dev mailing list to announce a Python implementation of various functions related to the cryptography used in Bitcoin... bitcoinops.org/en/newsletters…
Thanks a lot to @HRF for supporting my work and initiating this report. I hope it helps people understand the potential that a CISA softfork could bring to Bitcoin and why we are excited about it.

Tim Ruffing (@real_or_random) and Jonas Nick (@n1ckler) posted to the mailing list a link to the current draft BIP for ChillDKG, which describes a distributed key generation protocol compatible with FROST scriptless threshold signatures for Bitcoin... bitcoinops.org/en/newsletters…
🎉 Congratulations to our very own Tim Ruffing (@real_or_random) and Jonas Nick (@n1ckler), along with @yannickseurin from @Ledger, @chelseakomlo, and Ian Goldberg. They have received the 2024 Bitcoin Research Prize for their work on MuSig2 and FROST!
It's Taproot's birthday 🎂 Today we celebrate 3 years of Taproot, the most recent Bitcoin Soft Fork. While Taproot is famous for inadvertently enabling Ordinals, it contained many improvements that benefitted the entire Bitcoin ecosystem 🧵
libsecp256k1 v0.6.0 is out! Featuring the highly anticipated musig module and other improvements. In particular, the API functions now use a significantly more robust method to clear secrets from the stack before returning. Full change log: github.com/bitcoin-core/s… Thanks to…
My @Web3summit talk on Multi-Party Schnorr Signatures is available here: youtube.com/watch?v=4IYm6C… and slides here: elizabeth-crites.github.io/activities.html I gave a very high-level overview of this research area and standardization efforts, at a slow pace because my clicker was malfunctioning :)
🎉🎉🎉Finally! MuSig2 was merged into libsecp256k1, almost 5 years after the publication of the first paper draft. 🎉🎉🎉

The ChillDKG BIP is currently in draft, and we're looking for community feedback! If approved, it will be combined with another BIP to bring the full power of FROST to Bitcoin, reducing transaction costs and improving the privacy of multisig wallets. blog.blockstream.com/the-key-to-fro…
Tim Ruffing (@real_or_random) and Jonas Nick (@n1ckler) posted a BIP draft with reference implementation of ChillDKG, a protocol for securely generating keys to be used with FROST-style scriptless threshold signatures compatible with schnorr signatures... bitcoinops.org/en/newsletters…

@reardencode @lucasdcf @boyacaxa @rusty_twit @stevenroose3 Spiral is still hiring full-time for a Wizard. We're very open to funding consensus change R&D work! In addition to it being a high quality R&D project, we'd also require * no premature activation talk * no clown shows on social media * thorough risk and security analysis
@real_or_random and I published the first BIP draft of ChillDKG: Distributed Key Generation for FROST. It specifies a protocol for trustless creation of a threshold setup, e.g., for use in t-of-n wallets. ChillDKG is standalone: it doesn't require external secure channels or a…
