Benchmarks of the Pedersen, Poseidon, MiMC, and SHA256 hash functions in Circom circuits to help you weigh the trade offs of different ZK circuit hash algos.
Test with different hash inputs in my zkrepl!

bash ./compile.sh| Proof Size | Proover Time (M1 Macbook Air, 2020) | ETH Verification Gas Cost | |
|---|---|---|---|
| Pedersen | 4.2KB | 2.123s | N/A (so inefficient implementation is infeasible) |
| Poseidon | 112KB | 3.124s | 50k-55k |
| MiMC | 203KB | 2.617s | 55k-60k |
| SHA256 | 19MB | 64.492s | 30 |
