Struct Instance 

Source 
pub struct Instance {
    pub nf_signed: Nullifier,
    pub rk: VerificationKey<SpendAuth>,
    pub cmx_new: Base,
    pub van_comm: Base,
    pub vote_round_id: Base,

Expand description

Public inputs to the delegation circuit (14 field elements).

These are the values posted to the vote chain (§2.4) that both the prover and verifier agree on. The verifier checks the proof against these values without seeing any private witnesses.

Fields§

§nf_signed: Nullifier

The derived nullifier of the keystone note.

§rk: VerificationKey<SpendAuth>

The randomized spend validating key.

§cmx_new: Base

The extracted commitment of the output note.

§van_comm: Base

The governance commitment hash.

§vote_round_id: Base

The voting round identifier.

§nc_root: Base

The note commitment tree root (shared anchor).

§nf_imt_root: Base

The nullifier IMT root.

§gov_null: [Base; 5]

Per-note governance nullifiers (5 slots).

§dom: Base

The nullifier domain (ZIP §Nullifier Domains).

Implementations§

impl Instance

Source

pub fn from_parts( nf_signed: Nullifier, rk: VerificationKey<SpendAuth>, cmx_new: Base, van_comm: Base, vote_round_id: Base, nc_root: Base, nf_imt_root: Base, gov_null: [Base; 5], dom: Base, ) -> Self

Source

pub fn to_halo2_instance(&self) -> Vec<Scalar> ⓘ

Serializes the public inputs into the flat field-element vector that halo2’s MockProver::run, create_proof, and verify_proof expect.

The order must match the instance column offsets defined at the top of this file (NF_SIGNED, RK_X, RK_Y, CMX_NEW, etc.).
