Bulletproofs in Python

WARNING: Work-in-progress. Only meant for experimental purposes.

---

We use pyo3 to wrap the bulletproof implementation by dalek-cryptography in python.

Quickstart

Install latest development version from PyPI.

pip install pybulletproofs

To test the python library, run the following proof and verification.

from pybulletproofs import zkrp_prove, zkrp_verify

proof1, comm1, _ = zkrp_prove(2022, 32)
proof2, comm2, _ = zkrp_prove(2023, 32)

assert zkrp_verify(proof1, comm1)
assert !zkrp_verify(proof2, comm1)

Development

Dependencies

• Python 3.8 and up
• Rust 1.62.0-nightly (60e50fc1c 2022-04-04) and up

Building

We first create a python virtual environment, activate it, and install maturin into the virtual environment.

$ python -m venv .env
$ source .env/bin/activate
$ pip install maturin

To compile the Rust implementation into a python library, run the following code snippet.

$ maturin init
$ maturin develop

Alternatively, use the Dockerfile.
