Using the Coq proof assistant, it proved the zkVM's Halo2 circuits sound and knowledge sound across arithmetic, bitwise, memory, control-flow and function-call instructions. The work, which CertiK began in 2024, runs to more than 33,000 lines of machine-checked Coq and caught a critical design bug that auditing had missed. It arrives as Ethereum prepares to verify its own blocks with zkVM proofs, with the Ethereum Foundation targeting 128-bit provable security by the end of 2026.","thumbnail_url":"https://img.transistorcdn.com/KhCapPSRkLGL2Xw8888yuChkNRWthaKapLYTvNdu4W4/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzQxMTY2LzE2ODM1/ODIzMzAtYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
