Ethereum’s PeerDAS networking upgrade (a protocol for sampling data availability) has operated without a major incident for nearly 12 months, supporting higher blob capacity and a sharp decline in Layer 2 transaction costs. Validators need to inspect only about one-eighth of extended data, with erasure coding and 128-column distribution allowing the network to confirm availability without requiring any single node to hold the entire dataset. PeerDAS, formally EIP-7594, launched with the Fusaka hard fork on December 3, 2025, after testing across hundreds of nodes on a dedicated devnet. Blob targets increased from six to nine per block at launch to 10 on December 9 and 14 on January 7, 2026. Layer 2 transaction costs fell from $0.20-$0.50 before activation to $0.005-$0.02 in the first quarter of 2026, a decline of more than 95%. The reduction also reflects EIP-4844, which introduced blob-carrying transactions in early 2024 and separated blob fees from execution gas fees. PeerDAS extends that foundation while limiting the burden on individual validators. Researchers describe the design as decentralized data availability consensus, and its architecture is an early phase of Dankrad Feist’s broader danksharding proposal, which could eventually support thousands of blobs per block. The increase from six to 14 blobs in roughly five weeks suggests Ethereum’s developer community is comfortable accelerating capacity after establishing baseline stability.
