zerokit: A set of zero knowledge modules utilizing arkworks to produce an easy to use interface for RLN (rate limiting nullifier), formally described in an RFC (https://github.com/vacp2p/rfc-index/blob/main/vac%2F58%2Frln-v2.md) in system programming environments and the browser. It is primarily used in Waku (https://waku.org/) to provide privacy-preserving dos protection. It is meant to interface with the RLN contract deployed to sepolia and polygon zkevm testnet (https://github.com/vacp2p/rln-contract).
