func StartSignCommon(taproot bool, result *keygen.Config, signers []party.ID, messageHash []byte) protocol.StartFunc

type Signature struct {
	// R is the commitment point.
	R curve.Point
	// contains filtered or unexported fields
}

Signature represents the result of a Schnorr signature.

This signature claims to satisfy:

z * G = R + H(R, Y, m) * Y

for a public key Y.

func (sig Signature) Verify(public curve.Point, m []byte) bool

Verify checks if a signature equation actually holds.

Note that m is the hash of a message, and not the message itself.
