Overview
- Mainnet activation is set for slot 13,164,544 at approximately 21:49 UTC on Dec. 3, following successful testnet runs and audits reporting no critical issues.
- The upgrade deploys PeerDAS so validators verify sampled blob segments instead of full blobs, reducing bandwidth needs and lowering data costs for rollups.
- The default block gas limit rises to 60 million, expanding base‑layer throughput for both standard transactions and blob processing.
- Two Blob Parameter Only adjustments are scheduled for Dec. 9 and Jan. 7 to further expand blob capacity through a phased, monitored rollout.
- New user and developer primitives include preconfirmations for sub‑second transaction assurance and native P‑256 support enabling passkey/WebAuthn signatures.
