Ethereum Foundation discusses network scalability and design

Ethereum's peer-to-peer layer faces constraints like propagation latency and bandwidth due to blob throughput, a growing validator set, and demanding applications. Yiannis Psaras presents a talk for the Ethereum Foundation on what ETH can learn from other networks. The session introduces transport primitives such as QUIC and TLS 1.3, which offer fewer round trips and stream multiplexing without head-of-line blocking. It covers spreading messages through erasure-coded broadcast for large payloads like blocks and blobs, along with aggregation and batching for small and frequent messages. The presentation uses Solana and libraries like Iroh as examples of networks that have already adopted these approaches, concluding with how these pieces fit into the ETH roadmap.
