Zcash Releases New Model of Frost Signature Scheme

The Zcash Basis announced 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 can be used to signal transactions from the house owners of a signing key. The inspiration 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 wanted to make sure that performing multi-party signing operations might be each performant, safe, and indistinguishable from transactions signed by solely a single celebration.”
