Franck is currently leading the Waku project, a suite of protocol and network that enables censorship-resistant and private off-chain communications, using novel zero-knowledge technology to prevent spamming.

He joined the blockchain ecosystem for the Cypherpunk values, previously working on multi-chain private swap protocols.

The p2p networks of the Ethereum ecosystem generally draw the line to server nodes. True end users devices: mobiles, laptops, browsers, are excluded and use centralised APIs and gateways to access the p2p network. Removing sovereignty, censorship-resistance and privacy in the process.

In this lightning talk, we’ll review everything that can go wrong when trying to include resource restricted devices in a peer-to-peer network, using the most popular tools and libraries.

Stage 4

Bringing peer-to-peer networks to ALL the peers

RLN is a protocol designed to prevent DoS attacks in a privacy-preserving manner. It uses zero-knowledge proof to limit the number of actions a user can take. In a p2p network, it can be used to limit messages sent over a period of time by one sender. RLN’s latest upgrade limits to N (instead of 1) messages per epoch. Also, the Merkle tree is now built on-chain, greatly improving the UX.

Come learn how to use an implementation of RLNv2 to DoS protect a peer-to-peer network.
