EPF - Fourth Update

My last update was solely focused on light clients, since my project idea is to contribute to Helios Light Client implementation. For this update, I explored the peer-to-peer networking of the beacon chain in order to stop helios from relying on a centralized provider.

Consensus Layer P2P Networking

This is the main component of this update.

Next Steps

I'm working on an implementation of an adapter from discv5 to work along libp2p in rust, based on the current lighthouse CL client work.

zkFOCIL: SNARK-based Linkable Ring Signatures

Ethereum's FOCIL (Fork-choice enforced Inclusion Lists) mechanism aims to enhance censorship resistance by allowing committees of validators to force-include transactions in blocks. However, the current design exposes validator identities, creating potential vulnerabilities to targeted attacks. The zkFOCIL approach proposes using privacy-enhancing cryptography to protect validator identities while maintaining FOCIL functionality. Goal Explore practical approaches for implementing privacy-preserving inclusion lists using zero-knowledge proofs, with a focus on SNARK-based Linkable Ring Signatures. Objectives Core objectives Research SNARK-based approaches for implementing Linkable Ring Signatures in the context of zkFOCIL Prototype and benchmark implementations to evaluate viability Determine performance characteristics across different validator set sizes
