## Description

We'll look at Waku, the communication layer for Web3, and how it uses ZK for its service network. Specifically, we'll look at RLN-RELAY, a privacy-preserving p2p economic spam protection mechanism. We'll also look briefly at the history of different implementations, and how we plan to get the best of both worlds with Rust and Circom using ark-circom and Zerokit.
