Ron Rothblum on Fiat-Shamir Attacks, Flock and SNARK.fast - Zero Knowledge | Lyssna här

This week, Anna and Kobi are joined by Ron Rothblum, Professor of Computer Science at Technion and researcher at Succinct. They catch up on Ron’s move from theory into practice, including his work on the SP1 zkVM, Jagged Polynomial Commitments, and a recent Fiat-Shamir attack that exposed vulnerabilities in practical uses of GKR. Ron explains what the attack revealed about Fiat-Shamir’s security assumptions and why it prompted changes to deployed systems.

The conversation then explores Ron’s recent work on faster and more efficient proof systems, from Blaze, TensorSwitch, BOLT and Veil to Flock, a proof system for batch proving Boolean computations. They discuss how new approaches to polynomial commitments and error-correcting codes can improve prover performance, before turning to snark.fast and zkGolf, experiments using AI agents to optimise provers and circuits. Ron shares what these efforts reveal about AI-assisted research and engineering, and how pushing proving closer to the speed of ordinary computation could unlock entirely new applications for verifiable computation.
