Details
- Ethereum researchers published Protocol Update 002 outlining a multi-phase plan to scale blob throughput for Layer-2 networks, including the Fusaka upgrade targeting early November 2025 and Glamsterdam expected mid-2026.
- The Ethereum Foundation and core developers, including Barnabas Busa, Alex Stokes, and Raúl Kripalani, are leading coordination and implementation efforts for these protocol upgrades.
- Fusaka introduces PeerDAS, a data availability sampling method that allows nodes to verify blob data efficiently, supporting an increase from 6 to as many as 48 blobs per block without raising hardware demands.
- This scaling plan builds on foundational work like EIP-4844 (Dencun, March 2024) and draws momentum from the May 2025 Pectra upgrade, which previously raised blob storage limits for consensus nodes.
- Testing is underway on developer networks, with incremental blob capacity increases planned through Blob Parameter Only forks and bandwidth optimizations such as cell-level messaging to reduce data transfer overhead.
Impact
Ethereum’s roadmap addresses rising blob fees and reinforces its role as the leading platform for Layer-2 solutions. By increasing blob throughput eightfold by late 2025 without imposing greater hardware burdens, Ethereum is primed to sustain affordable scalability for DeFi, gaming, and AI growth as demand accelerates.
