Overview
- Mainnet activation is set for slot 13,164,544 at about 21:49 UTC on Dec. 3, following a final go-ahead on ACDC call #168 after successful Hoodi, Holesky, and Sepolia tests.
- PeerDAS (EIP-7594) will let validators sample portions of rollup blobs instead of downloading them in full, reducing bandwidth and unlocking higher data throughput for Layer 2s.
- Developers plan a staged rollout with mainnet activation first, incremental blob-capacity increases via Blob Parameter-Only forks, and subsequent hard forks to raise data limits further.
- Modeling cited by outlets suggests typical rollup fee reductions of roughly 15–40%, with larger cuts possible if blob supply exceeds demand for sustained periods.
- Some coverage reports a fivefold block gas limit increase to 150 million units in the release, a detail that has been reported but not uniformly corroborated by official sources.
