The Ethereum Foundation has released protocol update 002, detailing the blob data scaling roadmap. The plan is to significantly increase the data availability of the Ethereum L2 system, supporting scenarios 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 in a block from the current six to 48.
The main network capacity can be incrementally increased through Blob Parameter Hard Fork (BPO), which can theoretically achieve 8 times throughput improvement.
Bandwidth optimization techniques such as "cell-level messaging" will reduce network redundancy.
The Glamsterdam upgrade (expected mid-2026) will introduce PeerDAS v2, further expanding data availability.
Continue to study blob pool expansion and FullDAS technology to ensure that core values such as censorship resistance are maintained while expanding capacity.
This update marks Ethereum's shift from a "fork center" concept to a more flexible incremental optimization strategy, designed to accelerate the development of the L2 ecosystem.
