Zerokit

A set of Zero Knowledge modules, written in Rust and designed to be used in other system programming environments.

Initial scope

Focus on RLN and being able to use Circom based version through ark-circom, as opposed to the native one that currently exists in Rust.

Acknowledgements

• Uses ark-circom, Rust wrapper around Circom.

• Inspired by Applied ZKP group work, e.g. zk-kit.

• RLN library written in Rust based on Bellman.

• semaphore-rs written in Rust based on ark-circom.

• The circom witness calculation code of the rln crate is based on circom-witnesscalc by iden3. The execution graph file used by this code has been generated by means of the same iden3 software.
