gnark-plonky2-verifier
This is an in-progress implementation of a Plonky2 verifier in Gnark (supports Groth16 and PLONK). It currently is able to verify some dummy circuits, but not much more as many of the custom gates used in Plonky2 are currently not implemented.
Besides the verifier, there are some Gnark implementation of circuits in this repo that may be useful for other projects:
Requirements
Benchmark
To run the benchmark,
go run benchmark.go
Here are relevant numbers from a benchmark ran on an M1 Max with 10 CPU cores.

The circuit can be significantly optimized by using more efficient arithmetic for Goldilocks, among other things.
