}

Trait for the final machine of a two-round signing protocol.

Required Associated Types

type SignatureShare: Clone + PartialEq + Writable

SignatureShare message for this machine.

Required Methods

fn read_share<R: Read>(&self, reader: &mut R) -> Result<Self::SignatureShare>

Read a Signature Share message.

fn complete( self, shares: HashMap<Participant, Self::SignatureShare>, ) -> Result<S, FrostError>

Complete signing. Takes in everyone elses’ shares. Returns the signature.
