This is an instance of the Spend circuit.

Fields

params: &'a E::Paramsvalue_commitment: Option<ValueCommitment<E>>

Pedersen commitment to the value being spent

proof_generation_key: Option<ProofGenerationKey<E>>

Key required to construct proofs for spending notes for a particular spending key

payment_address: Option<PaymentAddress<E>>

The payment address associated with the note

commitment_randomness: Option<E::Fs>

The randomness of the note commitment

ar: Option<E::Fs>

Re-randomization of the public key

auth_path: Vec<Option<(E::Fr, bool)>>

The authentication path of the commitment in the tree

anchor: Option<E::Fr>

The anchor; the root of the tree. If the note being spent is zero-value, this can be anything.
