According to ChainCatcher, the Ethereum Foundation has officially announced Protocol Update 002, which provides a detailed overview of the Blob data expansion roadmap. This initiative aims to significantly enhance data availability for Ethereum L2 systems, supporting use cases such as real-time payments, DeFi, social media, and AI applications.
Key updates include:
The upcoming Fusaka upgrade will introduce the PeerDAS architecture, increasing the number of blobs per block from the current 6 to 48;
Gradual mainnet capacity growth through a blob parameter hard fork (BPO), theoretically enabling up to an 8x increase in throughput;
Bandwidth optimization technologies such as "cell-level messaging" will reduce redundant network communication;
The Glamsterdam upgrade (expected mid-2026) will introduce PeerDAS v2, further expanding data availability;
Ongoing research into blob pool expansion and FullDAS technology to ensure Ethereum’s core values, such as censorship resistance, are maintained during scaling;
This update marks Ethereum’s shift from a “fork-centric” approach to a more flexible incremental optimization strategy, aiming to accelerate the development of the L2 ecosystem.
