Struct FRIVerifier

source 
pub struct FRIVerifier<'a, F, FA, VCS>
where
    F: BinaryField,
    FA: BinaryField,
    VCS: VectorCommitScheme<F>,
{ /* private fields */ }
Expand description

A verifier for the FRI query phase.

The verifier is instantiated after the folding rounds and is used to test consistency of the round messages and the original purported codeword.
