## AI overview

Ethereum's Protocol Update 002 outlines an incremental approach to scaling blob capacity for L2 data availability. It describes PeerDAS in the Fusaka upgrade, Blob Parameter Only forks, networking improvements, mempool sharding, and research into next-generation data availability sampling.

## Source excerpt

Following up from Protocol Update 001, we'd like to introduce our approach to blob scaling. The L1 serves as a robust foundation for L2 systems to scale Ethereum, and a necessary component of secure L2 solutions is data availability provided by the L1. Data availability ensures that updates L2s make...
