Although the beam chain is still just a proposal for a future version of Ethereum’s consensus layer, we were pleased to host more than eighty curious people on the call. We are grateful for the growing interest in the project. Feel free to DM me if you also wanted to join one of our upcoming calls on ‘minslack’ (a more optimal validator exit queue design), Attester-Proposer-Separation and Three-Slot-Finality.

Coming back to the core topic of this call: p2p-networking. As a quick introduction: One of the main objectives is to come up with an effective networking protocol for peer discovery and message passing (gossiping) between nodes. Such protocol must strike the right balance between latency, message transportation resilience, and bandwidth usage. A key parameter is the size of messages distributed among peers. The substantial increase in size of post-quantum signatures in the context of the beam chain compared to current signatures necessitates exploring more optimal networking protocols

Setting the stage, @justindrake laid out a strawman proposal, leveraging the existing beacon chain network framework (libp2p) and adding a two-level permissionless aggregation layer - utilizing recursive aggregation for post-quantum signatures first on a subnet-level and later on a global level

@agemanning from SigmaPrime continued, highlighting a possible alternative to the currently used gossipsub protocol (for message gossiping) by proposing a more modular version called generalized gossipsub. This lets a network choose exactly how information spreads within it, even changing the rules for different types of information or at different times - improving its reliability and efficiency https://github.com/libp2p/specs/pull/664

Pop from the EF p2p networking team followed up with a different alternative (gossipsub v2), representing an evolution of the currently used gossipsub protocol, aiming at minimizing the duplication of messages floating across the network https://ethresear.ch/t/doubling-the-blob-count-with-gossipsub-v2-0/21893

Next up Kamil from Quadrivium presented a network topology for faster message distribution among validators called GRID, and shared their experience using it in the context of building a client on the polkadot network https://hackmd.io/@kamilsa/B1gqs7wqye
