Implementations

impl Proof

pub fn new(amount: Amount, keyset_id: Id, secret: Secret, c: PublicKey) -> Proof

Create new Proof

pub fn is_active(&self, active_keyset_ids: &[Id]) -> bool

Check if proof is in active keyset Ids

pub fn y(&self) -> Result<PublicKey, Error>

Get y from proof

Where y is hash_to_curve(secret)

impl Proof

pub fn sign_p2pk(&mut self, secret_key: SecretKey) -> Result<(), Error>

Sign Proof

pub fn verify_p2pk(&self) -> Result<(), Error>

Verify P2PK signature on Proof

Per NUT-11, there are two spending pathways after locktime:

1. Primary path (data + pubkeys): ALWAYS available
2. Refund path (refund keys): available AFTER locktime

The verification tries both paths - if either succeeds, the proof is valid.

impl Proof

pub fn verify_dleq(&self, mint_pubkey: PublicKey) -> Result<(), Error>

Verify proof Dleq

impl Proof

pub fn verify_htlc(&self) -> Result<(), Error>

Verify HTLC

Per NUT-14, there are two spending pathways:

1. Receiver path (preimage + pubkeys): ALWAYS available
2. Sender/Refund path (refund keys, no preimage): available AFTER locktime

The verification tries to determine which path is being used based on the witness provided, then validates accordingly.

pub fn add_preimage(&mut self, preimage: String)

Add Preimage
