Ethereum Locks In Dec. 3 Fusaka Upgrade With PeerDAS to Boost L2 Data Capacity

The release uses data-sampling to lower rollup posting costs, keeping Layer 1 as the settlement base.

Overview

  • Mainnet activation is set for slot 13,164,544, expected at 21:49 UTC on December 3, following ACDC call #168 and a successful Hoodi dress rehearsal.
  • PeerDAS (EIP-7594) allows validators to sample blob data instead of retrieving it in full, cutting bandwidth needs and enabling higher blob throughput for rollups.
  • Fusaka bundles additional proposals including Blob Parameter-Only forks to tune capacity, a blob base-fee floor, secp256r1 passkey support, deterministic proposer look-ahead, and gas-safety limits.
  • Developers plan a phased rollout that starts with activation and proceeds to incremental blob-capacity increases, with a later fork to raise data limits.
  • Coverage cites modeling that points to roughly 15–40% typical L2 fee reductions, with deeper cuts possible if supply outpaces demand, as teams monitor utilization and decentralization trade-offs.
