Summary

The Ethereum Foundation released protocol update 002 outlining a comprehensive Blob data expansion roadmap designed to enhance Layer 2 data availability. The roadmap features the Fusaka upgrade, which will introduce PeerDAS architecture to increase Blob capacity from 6 to 48 per block, alongside Blob Parameter Override (BPO) for gradual mainnet capacity growth with potential 8x throughput improvements. The Glamsterdam upgrade is expected by mid-2026, marking Ethereum's strategic shift from a fork-centric approach to a flexible incremental optimization strategy for network scalability.

Terms & Concepts
  • Blob Data: Data storage mechanism in Ethereum that enables efficient data availability for Layer 2 scaling solutions.
  • PeerDAS Architecture: A peer-to-peer data availability sampling system that allows increased Blob capacity while maintaining network efficiency.
  • Layer 2 Data Availability: The ability for Layer 2 scaling solutions to access and verify transaction data stored on the Ethereum mainnet.
