Zcash releases new version of Schnorr threshold signature scheme Frost

The Zcash Foundation announced the release of a new version of Schnorr’s threshold signature scheme Frost. The new version is a flexible round optimization Schnorr threshold signature scheme, designed to reduce the interaction between participants who jointly own a private signature key and want to use the private key to sign. Frost is a scheme jointly proposed by the Zcash Foundation and the University of Waterloo Cryptography, Security and Privacy Research Group UWCrySP, and is currently undergoing academic review.
