ProofVerifier

poi_rs::proof

Struct ProofVerifier 

Source 
pub struct ProofVerifier<'committee> { /* private fields */ }
Expand description

Verifies proofs against a trusted committee.

Verification is offline. The verifier does not resolve committee history or fetch missing proof data. The caller is responsible for supplying the committee that certified the proof’s checkpoint.

The value of Proof::chain is not used to select or validate the committee.

Implementations§

Source§

impl<'committee> ProofVerifier<'committee>

Source

pub const fn new(committee: &'committee Committee) -> Self

Creates a verifier using committee as its trust root.

Source

pub const fn committee(&self) -> &'committee Committee

Returns the committee used to verify checkpoint signatures.

Source

pub fn verify<'proof>( &self, proof: &'proof Proof, ) -> Result<VerifiedProof<'proof>, VerifyError>

Verifies a proof and all of its targets.

Verification checks that:

  • the committee certifies the checkpoint summary;
  • the checkpoint contents match the digest in that summary;
  • the transaction, effects, and optional events are internally consistent;
  • the transaction effects occur in the authenticated checkpoint contents;
  • the packaged user signatures match those committed by the checkpoint;
  • the event list is present exactly when the effects commit to events, and its digest matches;
  • every selected target matches the authenticated proof data.

On success, returns a VerifiedProof borrowing the authenticated targets from proof.

§Errors

Returns an error if any check fails.
