mpz is a collection of multi-party computation libraries written in Rust 🦀.

This project strives to provide safe, performant, modular and portable MPC software with a focus on usability.

See our design doc for information on design choices, standards and project structure.

This project is currently under active development and should not be used in production. Expect bugs and regular major breaking changes. Use at your own risk.

Core

• mpz-core - Assortment of low-level primitives.
• matrix-transpose - Bit-wise matrix transposition.
• clmul - Carry-less multiplication

Circuits
