Introducing Expander: The Fastest GKR Proof System to Date

TL;DR: We are excited to announce the benchmarking and open source of our zero-knowledge proof (ZKP) system, Expander, developed by Polyhedra Network. Expander can prove 4500 Keccak-f permutations per second on an Apple M3 Max Machine! This makes Expander the most efficient open-source-proof system in the industry to date. Having demonstrated its efficiency on our zkBridge, Expander will also revolutionize zkVM and zkML. Keccak-256 is a cryptographic hash function standardized by NIST in the ...
