Struct SuccinctReceipt 

#[non_exhaustive]
pub struct SuccinctReceipt<Claim> {
    pub seal: Vec<u32>,
    pub control_id: Digest,
    pub claim: MaybePruned<Claim>,
    pub hashfn: String,
    pub verifier_parameters: Digest,
    pub control_inclusion_proof: MerkleProof,
}

A succinct receipt, produced via recursion, proving the execution of the zkVM with a STARK.

Using recursion, a CompositeReceipt can be compressed to form a SuccinctReceipt. In this way, a constant sized proof can be generated for arbitrarily long computations, and with an arbitrary number of segments linked via composition.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

seal: Vec<u32>

The cryptographic seal of this receipt. This seal is a STARK proving an execution of the recursion circuit.

control_id: Digest

The control ID of this receipt, identifying the recursion program that was run (e.g. lift, join, or resolve).

claim: MaybePruned<Claim>

Claim containing information about the computation that this receipt proves.

The standard claim type is ReceiptClaim, which represents a RISC-V zkVM execution.

hashfn: String

Name of the hash function used to create this receipt.

verifier_parameters: Digest

A digest of the verifier parameters that can be used to verify this receipt.

Acts as a fingerprint to identify differing proof system or circuit versions between a prover and a verifier. It is not intended to contain the full verifier parameters, which must be provided by a trusted source (e.g. packaged with the verifier code).

control_inclusion_proof: MerkleProof

Merkle inclusion proof for control_id against the control root for this receipt.

Implementations

impl<Claim> SuccinctReceipt<Claim>

pub fn verify_integrity(&self) -> Result<(), VerificationError>

where Claim: Digestible + Debug,

Verify the integrity of this receipt, ensuring the claim is attested to by the seal.

pub fn verify_integrity_with_context( &self, ctx: &VerifierContext, ) -> Result<(), VerificationError>

where Claim: Digestible + Debug,

Verify the integrity of this receipt, ensuring the claim is attested to by the seal.

pub fn get_seal_bytes(&self) -> Vec<u8>

Return the seal for this receipt, as a vector of bytes.

pub fn seal_size(&self) -> usize

Number of bytes used by the seal for this receipt.

pub fn into_unknown(self) -> SuccinctReceipt<Unknown>

where Claim: Digestible,

Prunes the claim, retaining its digest, and converts into a SuccinctReceipt with an unknown claim type. Can be used to get receipts of a uniform type across heterogeneous claims.
