pub struct Verifier { /* private fields */ }Expand description
Configurable verifier for Miden execution proofs.
Verifier::verify performs final verification and rejects wire-backed partial proofs.
Verifier::verify_partial accepts wire-backed partial proofs, rehydrates their deferred
state using the standard precompile registry, verifies the Miden VM proof against the hydrated
root, and returns the Miden VM security level with the deferred obligation.
Implementations§
Source§impl Verifier
impl Verifier
Sourcepub const fn with_max_deferred_elements(
self,
max_deferred_elements: usize,
) -> Verifier
pub const fn with_max_deferred_elements( self, max_deferred_elements: usize, ) -> Verifier
Updates the deferred-state element budget used by Self::verify_partial.
Sourcepub fn verify(
&self,
proof: ExecutionProof,
claim: ExecutionClaim,
) -> Result<u32, VerificationError>
pub fn verify( &self, proof: ExecutionProof, claim: ExecutionClaim, ) -> Result<u32, VerificationError>
Returns the security level of the final proof if it proves a correct execution of the given claim.
If the proof contains STARK-backed precompile VM proof material, both the precompile VM proof and the Miden VM proof are verified, and the returned security level is the minimum of the verified proof security levels. If no precompile claims were produced, only the Miden VM proof is verified.
§Errors
Returns an error if:
- The provided proof does not prove a correct execution of the claim.
- The proof carries wire-backed deferred proof material, which is a partial/delegable form.
- The proof’s STARK-backed precompile VM proof, if present, does not verify against its public root.
Sourcepub fn verify_partial(
&self,
proof: ExecutionProof,
claim: ExecutionClaim,
) -> Result<(u32, Unsettled), VerificationError>
pub fn verify_partial( &self, proof: ExecutionProof, claim: ExecutionClaim, ) -> Result<(u32, Unsettled), VerificationError>
Verifies a partial proof and returns its Miden VM security level and hydrated deferred state.
Partial verification accepts only wire-backed deferred proof material. The wire is hydrated using the standard precompile registry and this verifier’s deferred-element budget, then the Miden VM STARK proof is verified against the hydrated state’s root.
If no budget override was configured with Self::with_max_deferred_elements, partial
verification uses DEFAULT_MAX_DEFERRED_ELEMENTS.
§Errors
Returns an error if:
- The proof is not wire-backed partial proof material.
- The wire cannot be hydrated under the standard precompile registry and configured budget.
- The provided proof does not prove a correct execution of the program against the hydrated deferred root.
