On Ep. 70 of Infinite Jungle, Christine chats with founder of ProbeLab, Yiannis Psaras, about a data-driven study his team conducted on Ethereum node bandwidth availability. The study (linked in the show notes) measured the bandwidth availability of 70% of online and reachable nodes in the Ethereum network. It found that the mean available bandwidth for nodes stayed between 18 to 23 mbps, indicating that nodes do have additional capacity for packaging more blobs into blocks. Yiannis supported the decision by Ethereum protocol developers to include a blob capacity increase from 3/6 to 6/9 target/max blobs per block in the Pectra upgrade. Finally, he shared improvements that could be made to Ethereum’s P2P network to alleviate bandwidth constraints and enforce geographic decentralization of nodes.
