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.

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 :)

Pretty interesting read from someone who seemed to be less optimistic than others about the practicality of quantum computers in the past. > "I’ve felt like the race to build a scalable fault-tolerant quantum computer is actually underway. Like people are no longer merely giving…

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…

@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…
