4/ @TimBeiko on the future on All Core Devs

timbeiko.eth

@TimBeiko

Reconfiguring AllCoreDevs

To deliver on Ethereum's ambitious L1 roadmap, we should decouple planning and execution. To that end, I'm proposing we reorient ACD to focus on scoping future forks, and elevate our existing testing calls as the main venue for the current ones.

12/ @rudolf6_ on fixing fragmentation

@rudolf6_

Message passing is a key piece to fixing fragmentation on ethereum

ERC-7786 - a neutral, unified standard to allow apps to work with any messaging format, across all chains

barnabe.eth

@barnabemonnot

Thought this was a good prompt to give an update on my own journey with rollup economics and validator incentives. These are top-of-mind topics for many in EF Research and out, framing it more from my own context here (thanks @francescoswiss for the shoutout!)
