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.
