Zcash Foundation and University of Waterloo release rounds to optimize Schnorr threshold signature scheme, saving signature overhead

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.
