Bip schnorr signatures

WebIn cryptography, a Schnorr signature is a digital signature produced by the Schnorr signature algorithm that was described by Claus Schnorr. It is a digital signature scheme known for its simplicity, among the first whose security is based on the intractability of certain discrete logarithm problems. WebJul 7, 2024 · By Jonas Nick. We are excited to share the current progress on our research into the aggregation of signatures based on curve secp256k1: There is now an early draft Bitcoin Improvement Proposal (BIP) for non-interactive half-aggregation of BIP 340 Schnorr signatures.This proposal has a variety of potential applications in the Bitcoin ecosystem.
