Keccak256 hash function (ethereum version) implemented in circom. Spec: https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.202.pdf
Warning: WIP, this is an experimental repo.
Initial version works, compatible with Ethereum version of Keccak256.
It needs around 150848
(151k
) constraints.
For context: Rapidsnark proof generation time:
- 1.1M constraints -> 7 seconds (8 CPU)
- 128M constraints -> <2min (64 CPU)
