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 might be used to signal transactions from the house owners of a signing key. The muse commented on the motivations behind the choice to improve:
“Our resolution 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 at this time. 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 occasion.”
