Fuzzing Zero-Knowledge Infrastructure

Duration: 00:22:32

Speaker: Valentin Wüstholz

Type: Talk

Expertise: Intermediate

Event: Devcon

Date: Nov 2024

Zero-knowledge (ZK) infrastructure is highly complex and highly critical for the correct operation of L2 chains; that is, a single bug can result in massive financial and reputational damage. To find such potential million-dollar bugs before they are exploited, we have developed a novel fuzzing technique that can find logic flaws that impact liveness or safety of ZK infrastructure. Our fuzzer has already found 16 such issues in four ZK systems, namely Circom, Corset, Gnark, and Noir.
