Types

type SNPrivacyProof

type SNPrivacyProof struct {
	// contains filtered or unexported fields

SNPrivacyProof represents a zero-knowledge proof for proving the the serial number is correctly generated from the secret key and the SND with the following formula: SN = (sk + snd)^-1 * G[0].

func (SNPrivacyProof) Bytes

func (proof SNPrivacyProof) Bytes() []byte

Bytes returns the byte-representation of an SNPrivacyProof.

func (SNPrivacyProof) GetComInput

func (proof SNPrivacyProof) GetComInput() *crypto.Point

GetComInput returns the input commitment of an SNPrivacyProof.

func (SNPrivacyProof) GetComSK

func (proof SNPrivacyProof) GetComSK() *crypto.Point

GetComSK returns the secret key commitment of an SNPrivacyProof.

func (SNPrivacyProof) GetSN

func (proof SNPrivacyProof) GetSN() *crypto.Point

GetSN returns the serial number of an SNPrivacyProof.
