An ecosystem for developing and programming with zkSNARKs


arkworks is a Rust ecosystem for zkSNARK programming. Libraries in the arkworks ecosystem provide efficient implementations of all components required to implement zkSNARK applications, from generic finite fields to R1CS constraints for common functionalities.

Getting started

Below are some resources for getting started working with arkworks crates:

Getting Involved

We have a Discord community where folks can ask questions and learn about zkSNARK programming. We also have a Twitter where we (infrequently) post updates.

Repo index

Working with SNARKs

  • snark - defines interfaces for a SNARK, for your application to generically use them
  • relations - defines interfaces for relations, e.g. r1cs, AIR

SNARK proving systems

Fully packaged SNARK crates

  • groth16
  • marlin - universal setup SNARK for r1cs
  • gm17
  • gemini - an elastic proof system for streaming inputs
  • ripp -inner pairing product argument system

Circuit building
