Circuit size field discrepancy in ECCVM recursive verifier #1040

Open ledwards2225 opened 1 week ago

ledwards2225 commented 1 week ago

The circuit size (required as a witness FF in the ZM recursive verifier) cannot be extracted from the transcript as an FF (bigfield) in the ECCVM recursive verifier. It is thus extracted as a BF and converted to an FF. Resolution may be an update to the transcript functionality or a change in the input type in ZM to match the builder FF.
