BTW, I really liked @ethclientsummit , that's what I miss in events nowadays, I prefer smaller, content packed events, made by real builders. Looking forward for future editions.

The case for stronger RPC standards from @SCBuergel @hoprnet
π Sebastian BΓΌrgel (Gnosis & HOPR) argues that Ethereum needs stronger RPC standards. Inconsistent APIs like eth_getLogs break reliability and push devs toward centralized infra. He calls for a working group to fix the RPC layer. @SCBuergel @hoprnet

The Besu Fleet client is open source as of today! @gtschulte @HyperledgerBesu at @ethclientsummit by EF and Ethstaker
@HyperledgerBesuβs own @gtschulte is bringing a deep dive into reactive RPC scaling at EthClient Summit. How to scale nodes with minimal storage, what it costs, what you gain, and how Besu routes requests intelligently under the hood. Gonna be a good one.
