Kimchi

This repository contains kimchi, a general-purpose zero-knowledge proof system for proving the correct execution of programs.

You can read more about this project on the Kimchi book.

Organization

The project is organized in the following way:

  • book/. The mina book, RFCs, and specifications.
  • cairo/. A Cairo runner written in rust.
  • circuit-construction/. Circuit writer.
  • curves/. The elliptic curves we use (for now just the pasta curves).
  • groupmap/. Used to convert elliptic curve elements to field elements.
  • hasher/. Interfaces for mina hashing.
  • kimchi/. Our proof system.
  • ocaml/. Ocaml bindings generator tool.
  • oracle/. Implementation of the poseidon hash function.
  • poly-commitment/. Polynomial commitment code.
  • signer/. Interfaces for mina signature schemes.
  • tools/. Various tooling to help us work on kimchi.
  • utils/. Collection of useful functions and traits.
