Struct sn_dbc::SpentProof
source · [−]pub struct SpentProof {
pub content: SpentProofContent,
pub spentbook_pub_key: PublicKey,
pub spentbook_sig: Signature,
}
Expand description
SpentProof’s are constructed when a DBC is logged to the spentbook.
Fields
content: SpentProofContent
data to be signed
spentbook_pub_key: PublicKey
The Spentbook who notarized that this DBC was spent.
spentbook_sig: Signature
The Spentbook’s signature notarizing the DBC was spent. signing over SpentProofContent. (KeyImage, RingCtTransaction, and public_commitments).
Implementations
sourceimpl SpentProof
impl SpentProof
sourcepub fn transaction_hash(&self) -> Hash
pub fn transaction_hash(&self) -> Hash
get transaction hash
sourcepub fn public_commitments(&self) -> &Vec<Commitment>
pub fn public_commitments(&self) -> &Vec<Commitment>
get public commitments
sourcepub fn verify<K: KeyManager>(&self, tx_hash: Hash, verifier: &K) -> Result<()>
pub fn verify<K: KeyManager>(&self, tx_hash: Hash, verifier: &K) -> Result<()>
verify this SpentProof
checks that the input transaction hash matches the tx_hash that was signed by the spentbook and verifies that spentbook signature is valid for this SpentProof.
note that the verifier must already hold (trust) the spentbook’s public key.
