Tim Ruffing (Tim Ruffing) and Jonas Nick (ncklr) 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…

What if we could bring STARKs to Bitcoin without softforks and optimize costs later? 🤔 Enter Simplicity — an experimental script VM by Blockstream Research that would enable that. We built a PoC STARK verifier in Simplicity to explore its potential. Here’s what we learned: 🧵👇

Yosh, let's STARK the whole Bitcoin world. Hey Blockstream we built a PoC STARK verifier in Simplicity. A small step, but it shows Simplicity's potential for bringing efficient STARKs to Liquid Network 🌊 sidechain. Looking for Bitcoin devs to contribute. cc Adam Back

Exciting to see this brilliant exploration of Simplicity's capabilities! This proof-of-concept STARK verifier demonstrates exactly the kind of innovation we envisioned, bringing powerful succinct proofs to Bitcoin sidechains. Remarkable achievement!

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: Tim Ruffing Yannick Seurin! 👇

Huge milestone from Blockstream Research’s cryptography team! Congratulations @N1ckler, Tim Ruffing (Blockstream), and Yannick Seurin (Ledger) on introducing DahLIAS - a breakthrough in Bitcoin signature aggregation using secp256k1. x.com/n1ckler/status…

JUST IN: 🧪 ncklr unveils DahLIAS, a new protocol for faster cross-input signature aggregation on #Bitcoin, aiming to boost efficiency, scalability, and privacy while reusing Bitcoin’s secp256k1 curve. btctimes.com/new-research-u…

In Podcast #348 we had on Jonas Nick (ncklr), Jameson Lopp (Jameson Lopp), Steven Roose (Steven Roose), Gregory Sanders (instagibbs), and Salvatore Ingala (Salvatore Ingala): - secp256k1lab - discussions about quantum computer theft and resistance - discussions about a CTV+CSFS soft

Come build the future with Blockstream! We're hiring for 16 positions, including Technical Product Manager (Simplicity) & Smart Contract Engineer. blockstream.com/careers/

secp256k1lab: a new Python library that makes BIPs easier to write, read, and reason about. New from Blockstream research. bitcoinmagazine.com/technical/secp…

A transaction spending a STARK-locked output is just 78k WU on Liquid! If Simplicity VM was integrated into Bitcoin mainnet, verifying a STARK proof could cost only ~$70 🤯 blockstream.info/liquidtestnet/… Ofc this isn't a full solution yet: it uses a small, insecure field and doesn't

Yesterday Murch and Schmidty had on Jonas Nick (ncklr) and Salvatore Ingala (Salvatore Ingala) to cover Newsletter #351: - The DahLIAS Interactive aggregate signature scheme - Standardized backup for wallet descriptors - Stack Exchange questions including: half-aggregated

We're bringing the signal to The Bitcoin Conference. Talks from Adam Back and Sean Bill cover BTC infrastructure and capital markets. ncklr and Andrew Poelstra from Blockstream Research dive into MEV and quantum. Visit booth #2121, stack a Blockstream Jade, and see what we're building.

Following today's Elements 23.3.0 release, Simplicity is now one step closer to deployment on Liquid mainnet. A short 🧵. github.com/ElementsProjec…

Not ECDSA. Not Schnorr. Meet DahLIAS 🌺 A full aggregate signature scheme, that actually works on Bitcoin’s curve! New breakthrough from ncklr, Tim Ruffing, and Yannick Seurin 👇 bitcoinmagazine.com/technical/not-…
