Selecting Optimal Outbound Neighbors (SOON) for fast, bandwidth‑efficient propagation in P2P networks

by Thomas and Marios - October 27th, 2025 Thanks to Marco, Yann, Anders, Caspar, Raul and Csaba for their valuable feedback and comments. TLDR; Ethereum’s P2P layer currently forwards messages such as blocks, attestations, and blobs to randomly selected peers, considering latency only weakly through peer scoring. As a result, messages often travel along slow or overlapping routes, increasing bandwidth usage and propagation delay. In this post, we introduce SOON (Selecting Optimal Outbound ...

The paths of least resistance: Introducing WFR-Gossip

By Thomas Thiery – June 26th, 2025 Thanks to Léonard Monsaingeon, Caspar Schwarz-Schilling, Julian Ma, Anders Elowsson, Raúl Kripalani, Yann Vonlanthen, Csaba Kiraly and Marco Munizaga for the great feedback and comments on earlier versions of this post. TL;DR Classic Gossipsub floods the network with many duplicates, wasting bandwidth. Wasserstein-Fisher-Rao (WFR) Gossip addresses this by treating propagation as an optimal-transport problem: nodes forward messages preferentially along lowe...

Fork-Choice enforced Inclusion Lists (FOCIL): A simple committee-based inclusion list proposal

^focil => fossil => protocol ossification by Thomas, Barnabé, Francesco and Julian - June 19th, 2024 This design came together during a small, week long, in-person gathering in Berlin with RIG and friends to discuss censorship resistance, issuance, and Attester-Proposer-Builder-Consensus-Execution-[insert here] Separation. Thanks to Luca, Terence, Toni, Ansgar, Alex, Caspar and Anders for discussions, feedback and comments on this proposal. tldr In this post, we introduce Fork-Choice enfo...

Anonymous Inclusion Lists (anon-ILs)

by Thomas Thiery and Luca Zanolini, in collaboration with Mary Maller, Mark Simkin, and Antonio Sanso – May 23rd, 2024 Special thanks to Julian Ma, Barnabé Monnot and Francesco D’Amato for helpful comments and feedback. Introduction Relying on a few sophisticated entities for building blocks on Ethereum weakens the network’s censorship resistance properties. Currently, more than 60% of blocks are made by builders who actively censor transactions interacting with sanctioned addresses. As a res...
