5/ @VitalikButerin proposes changes to make Ethereum L1 nodes easier and lighter to run, especially on constrained hardware.
How to make Ethereum L1 scaling more friendly to users running local nodes for personal use:

A local-node-favoring delta to the scaling roadmap
Special thanks to Micah Zoltu, Toni Wahrstätter, Justin Traglia and pcaversaccion for discussion… The most common criticism of increasing the L1 gas limit, beyond concerns about network safety, is...
6/ @drakefjustin says real-time proving is coming — pushing Ethereum toward a more responsive and efficient design.
real-time proving is here Mainnet EVM blocks proven in under 1 Ethereum slot (12s). Goosebumps.
Succinct proves every Ethereum L1 block:
→ 94% in <12s
→ 99% in <13s
→ 99.9% in <12s, soon™
Yesterday RISC Zero unveiled a $120K home GPU cluster—proofs expected in

8/ @barnabemonnot outlines short/medium-term L1 upgrades that can improve UX without full state expiry or statelessness.
The Ethereum L1 is scaling, with active work for short- and medium-term improvements. @dankrad here tells us the tech ready.

9/ @dankrad reflects on the tradeoffs and benefits of shorter slot times as Ethereum’s consensus evolves.
My goal:
6s for Glamsterdam
4s for (Glamsterdam +1)
...
The headline target will be 1s.
Beyond 4s we need to do some deeper changes to consensus, which we're still working on.

Where are the shorter slot times @dankrad? 6 seconds to start with and how we plan for 1s?
10/ @SpaceandTimeDB integrates Ethereum onchain data into Microsoft Fabric, enabling data analysts to directly access blockchain insights.
Just announced at #MSBuild: Space and Time indexed blockchain data will be integrated with @Microsoft Fabric.As part of the integration, Microsoft developers will be able to access Space and Time indexed data from Bitcoin, @SuiNetwork, and @ethereum through Fabric.
