Fields

owner_base: Owner

This is the owner’s well-known key. owner_base.public_key() may be published and multiple payments sent to this key by various parties. It is useful for accepting donations, for example.

The SecretKey may or not be present. If it is present, then the Dbc is considered ownerless (aka bearer) and may be spent by anyone in possession of it.

When the SecretKey is not present, then the Dbc can only be spent by the party holding the SecretKey, ie the Dbc recipient that generated the PublicKey.

This key is only a client/wallet concept. It is NOT actually used in the transaction and never seen by the Spentbook.

The “real” key used in the transaction is derived from this key using a random derivation index, which is stored (encrypted) in owner_derivation_cipher.

owner_derivation_cipher: Ciphertext

This indicates which index to use when deriving the “real” owner key from the owner_base.

This index is stored in encrypted form, and is encrypted to owner_base.public_key(). So the true owner is unknown to anyone not in posession of owner_base.secret_key().

amount_secrets_cipher: Ciphertext

This is the AmountSecrets (aka RevealedCommitment) encypted to the derived public key, which can be obtained via: self.owner_base.derive( self.owner_base.secret_key().decrypt(self.owner_derivation.cipher() ).public_key()
