Ethereum released protocol update 002 to improve the data availability of the Ethereum L2 system.

CoinVoice has recently learned that according to the official announcement from the Ethereum Foundation, protocol update 002 provides a detailed introduction to the Blob data expansion roadmap. This plan aims to significantly enhance the data availability of Ethereum L2 systems, supporting real-time payments, Decentralized Finance, social media, and AI applications.

Key updates include:

The upcoming Fusaka upgrade will introduce the PeerDAS architecture, increasing the number of Blobs in a block from the current 6 to 48; through the Blob parameter hard fork (BPO), a gradual increase in mainnet capacity will be achieved, theoretically allowing for an 8-fold throughput improvement; bandwidth optimization technologies such as "unit-level latest information delivery" will reduce network redundancy communication; the Glamsterdam upgrade ( is expected to introduce PeerDAS v2 in mid-2026 ), further expanding data availability; ongoing research on Blob pool expansion and FullDAS technology ensures that Ethereum's core values, such as resistance to censorship, are maintained while scaling.

This update marks Ethereum's shift from the "forking center" concept to a more flexible incremental optimization strategy, aimed at accelerating the development of the L2 ecosystem.
