snarkpy

A zk-SNARK implemented in Python & Rust compatible with snarkjs

⚠️ It's not fully tested, so don't use it for production.

Install

# Install maturin if not installed
pipx install maturin

# Install rustup if not installed
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

git clone https://github.com/y011d4/snarkpy.git
cd snarkpy
pytyhon3 -m venv venv
source venv/bin/activate
make install

If you don't want to install locally, you can also use docker image:

docker run --rm -v $PWD:/work -it ghcr.io/y011d4/snarkpy:latest bash

Usage

First, prepare circuit_final.zkey, witness.wtns and verification_key.json by referring to the README in snarkjs. If you only need test data, you can make them by just typing make test-data.

# plonk prove
snarkpy plonk prove zkey wtns proof.json public.json

# plonk verify
snarkpy plonk verify vkey public.json proof.json

TODO

• Implement other algorithms than PLONK.
• Implement EC by myself and replace py_ecc.
• Replace mathematical implementation like Polynomial or GF with implementation Rust using PyO3.
