Aggregate signatures are the cryptographic requirement for cross-input signature aggregation (CISA) @n1ckler joined us to talk about DahLIAS, a scheme that does exactly that
Jonas Nick (@n1ckler) joined Brink engineers to discuss the DahLIAS interactive aggregate signature scheme: - DahLIAS overview - Secp256k1 compatibility - DahLIAS vs FROST/MuSig2 - Interactivity requirements - Cross-input signature aggregation (CISA) - Key tweaking - Q&A
Great digest of the Quantum Bitcoin Summit as well as the perceived state of quantum and Bitcoin broadly
This week, @PresidioBitcoin hosted the Bitcoin Quantum Summit (pbquantum.com). I was thrilled to be invited to attend, and wanted to write up a thread about what I learned this week. I’ll save my commentary for the end, and start with where we are, the challenges we…
