TechFlow news, August 22 — The Ethereum Foundation released Protocol Update 002, detailing the roadmap for blob data scaling. This initiative aims to significantly enhance data availability for Ethereum's Layer 2 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
- Progressive mainnet capacity growth via Blob Parameter Hard Fork (BPO), enabling up to 8x throughput improvement in theory
- Bandwidth optimization techniques such as "cell-level messaging" to reduce redundant network communication
- The Glamsterdam upgrade (expected mid-2026) will introduce PeerDAS v2, further expanding data availability
- Ongoing research into blob pool scaling and FullDAS technology to ensure scalability while preserving Ethereum’s core values like censorship resistance
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 Layer 2 ecosystem.
