fix: Check consistency between FRI codeword and polynomial - #6
Merged
Conversation
When verifying proofs, verify the consistency between the FRI polynomial and the last FRI codeword. This missing check corresponds to the soundness error identified in Triton VM version 1. By verifying this correspondence we can soundly validate version 1 proofs, provided that no recursion is involved. For the redemption claims, no recursion is involved. So with this patch we can still soundly verify all redemption claims.

Very cool. Looks correct to me.
