Ethereum releases protocol update 002 to enhance data availability for Ethereum L2 systems

ChainCatcher news, according to the official announcement from the Ethereum Foundation, the protocol update 002 details the Blob data expansion roadmap. This plan aims to significantly enhance the data availability of Ethereum L2 systems, supporting scenarios such as real-time payments, DeFi, social media, and AI applications.

Key updates include:

1. The upcoming Fusaka upgrade will introduce the PeerDAS architecture, increasing the number of Blobs in a block from the current 6 to 48;
2. Gradual growth of mainnet capacity through the Blob Parameter Hard Fork (BPO), theoretically achieving an 8-fold increase in throughput;
3. Bandwidth optimization technologies such as "cell-level messaging" will reduce network redundant communication;
4. The Glamsterdam upgrade (expected in mid-2026) will introduce PeerDAS v2, further expanding data availability;
5. Ongoing research on Blob pool expansion and FullDAS technology to ensure core values of Ethereum, such as resistance to censorship, are maintained while scaling;

This update marks a shift for Ethereum from the "fork-centric" concept to a more flexible incremental optimization strategy, aimed at accelerating the development of the L2 ecosystem.
