Used for building proofs and checking if the output belongs to the wallet

Required methods

fn rewind_nonce(
    &self,
    secp: &Secp256k1,
    commit: &Commitment
) -> Result<SecretKey, Error>

Create a BP nonce that will allow to rewind the derivation path and flags

fn private_nonce(
    &self,
    secp: &Secp256k1,
    commit: &Commitment
) -> Result<SecretKey, Error>

Create a BP nonce that blinds the private key

fn proof_message(
    &self,
    secp: &Secp256k1,
    id: &Identifier,
    switch: &SwitchCommitmentType
) -> Result<ProofMessage, Error>

Create a BP message

fn check_output(
    &self,
    secp: &Secp256k1,
    commit: &Commitment,
    amount: u64,
    message: ProofMessage
) -> Result<Option<(Identifier, SwitchCommitmentType)>, Error>

Check if the output belongs to this keychain
