This is an in-progress implementation of a [Plonky2](https://github.com/mir-protocol/plonky2) verifier in Gnark. 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: |
||||
|
|
||||
|
- [Goldilocks](https://github.com/succinctlabs/gnark-plonky2-verifier/blob/main/field/field.go) |
||||
|
- [Poseidon](https://github.com/succinctlabs/gnark-plonky2-verifier/blob/main/poseidon/poseidon.go) |
||||
|
- [FRI](https://github.com/succinctlabs/gnark-plonky2-verifier/blob/main/plonky2_verifier/fri.go) |
||||
|
|
||||
|
## Requirements |

|
|

|
- [Go (1.20.1+)](https://go.dev/doc/install) |

|
|

To run the benchmark, |
To run the benchmark, |
||||
``` |
``` |
||||
go run benchmark.go |
go run benchmark.go |
||||
``` |
|
||||
|
``` |
||||
|
|

|
Here are relevant numbers from a benchmark ran on an M1 Max with 10 CPU cores. |
||||
|
|
||||
|

# of constraints: 6740784 |
||||
|
circuit compilation time: 19 minutes, 33 sec. |
||||
|
witness generation time: < 1 second |
||||
|
groth16 setup: 8 minutes 23 seconds |
||||
|
proof generation: 23 seconds |
||||
|
proof verification: < 1 second |

|
``` |

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