The Zcash Basis introduced an up to date model of its flexible-optimized schnorr threshold signature scheme, FROST. This replace goals to cut back interactions between members.
FROST is the results of a collaboration between Zcash and the College of Waterloo.
FROST signatures shall be used to signal transactions from the homeowners of a signing key. The inspiration commented on the motivations behind the choice to improve:
“Our choice to design a brand new threshold scheme stemmed from the will to enhance the state of threshold signature analysis to match the wants of Zcash customers as we speak. Particularly, we would have liked to make sure that performing multi-party signing operations may very well be each performant, safe, and indistinguishable from transactions signed by solely a single social gathering.”
