Struct storage_proofs::circuit::zigzag::ZigZagCircuit

pub struct ZigZagCircuit<'a, E: JubjubEngine, H: 'static + Hasher> { /* fields omitted */ }

ZigZag DRG based Proof of Replication.

Fields

• params - parameters for the curve
• public_params - ZigZagDrgPoRep public parameters.
• 'layers' - A vector of Layers – each representing a DrgPoRep proof (see Layers type definition).

Methods

impl<'a, H: Hasher> ZigZagCircuit<'a, Bls12, H>

Trait Implementations

impl<'a, E: JubjubEngine, H: Hasher> CircuitComponent for ZigZagCircuit<'a, E, H>

type ComponentPrivateInputs = ()

impl<'a, H: 'static + Hasher> CompoundProof<'a, Bls12, ZigZagDrgPoRep<'a, H>, ZigZagCircuit<'a, Bls12, H>> for ZigZagCompound

fn generate_public_inputs(
    pub_in: &<ZigZagDrgPoRep<H> as ProofScheme>::PublicInputs,
    pub_params: &<ZigZagDrgPoRep<H> as ProofScheme>::PublicParams,
    k: Option<usize>
) -> Vec<Fr>

generate_public_inputs generates public inputs suitable for use as input during verification of a proof generated from this CompoundProof's bellperson::Circuit (C). These inputs correspond to those allocated when C is synthesized.

fn circuit<'b>(
    public_inputs: &'b <ZigZagDrgPoRep<H> as ProofScheme>::PublicInputs,
    _component_private_inputs: <ZigZagCircuit<'a, Bls12, H> as CircuitComponent>::ComponentPrivateInputs,
    vanilla_proof: &'b <ZigZagDrgPoRep<H> as ProofScheme>::Proof,
    public_params: &'b <ZigZagDrgPoRep<H> as ProofScheme>::PublicParams,
    engine_params: &'a <Bls12 as JubjubEngine>::Params
) -> ZigZagCircuit<'a, Bls12, H>

circuit constructs an instance of this CompoundProof's bellperson::Circuit. circuit takes PublicInputs, PublicParams, and Proof from this CompoundProof's proof::ProofScheme (S) and uses them to initialize Circuit fields which will be used to construct public and private inputs during circuit synthesis.

fn blank_circuit(
    public_params: &<ZigZagDrgPoRep<H> as ProofScheme>::PublicParams,
    params: &'a <Bls12 as JubjubEngine>::Params
) -> ZigZagCircuit<'a, Bls12, H>

fn setup<'b>(sp: &SetupParams<'a, 'b, E, S>) -> Result<PublicParams<'a, E, S>> where
    E::Params: Sync, 

fn partition_count(public_params: &PublicParams<'a, E, S>) -> usize

fn prove<'b>(
    pub_params: &'b PublicParams<'a, E, S>,
    pub_in: &'b S::PublicInputs,
    priv_in: &'b S::PrivateInputs,
    groth_params: &'b Parameters<E>
) -> Result<MultiProof<'b, E>> where
    E::Params: Sync, 

prove is equivalent to ProofScheme::prove.

fn verify(
    public_params: &PublicParams<'a, E, S>,
    public_inputs: &S::PublicInputs,
    multi_proof: &MultiProof<E>,
    requirements: &S::Requirements
) -> Result<bool>

fn circuit_proof<'b>(
    pub_in: &S::PublicInputs,
    vanilla_proof: &S::Proof,
    pub_params: &'b S::PublicParams,
    params: &'a E::Params,
    groth_params: &Parameters<E>
) -> Result<Proof<E>>

circuit_proof creates and synthesizes a circuit from concrete params/inputs, then generates a groth proof from it. It returns a groth proof. circuit_proof is used internally and should neither be called nor implemented outside of default trait methods.

    public_params: &S::PublicParams,
