The Zcash Foundation and UWCrySP scholar Chelsea Komlo of the University of Waterloo's Cryptography, Security and Privacy Research Group jointly published the paper "Flexible, round-optimized Schnorr threshold signature scheme FROST", which aims to achieve a round of asynchronous threshold signatures. Unlike signatures in unilateral settings, threshold signatures require collaboration between multiple signers, and each signer has a public private key. Therefore, the generation of signatures in threshold signatures will result in overhead due to multiple rounds of signatures between signers. The proposed FROST is a flexible round-optimized Schnorr threshold signature scheme that can improve the existing technology level to reduce signatures. Network overhead in operation.
