Prover Side Performance Test of Groth16 of Hash Functions

This is a performance test of the prover side of the Groth16 proof system for hash functions. The test will be conducted on the following hash functions:

SHA256
MiMC
Poseidon
Pedersen

Groth16 has constant proof size and verification time. But the prover side has a variable time and space complexity depending on the circuit complexity. So, we will analyze the prover side performance of the Groth16 proof system for the above hash functions on the following parameters:

WASM File Size
R1CS File Size
Witness File Size
Prover Key Size
Prover Time

Results

WASM File Sizes

R1CS File Sizes

Witness File Sizes

Prover Key Sizes

Prover Runtimes

Requirements

Circom: 2.1.8
NodeJS: 20.10.0
SnarkJS: 0.7.3
