Overview

  • Public testnets are slated for Holesky on Oct. 1, Sepolia on Oct. 14, and Hoodi on Oct. 28 ahead of mainnet activation.
  • Developers plan Blob Parameter Only forks to raise blob targets from 6/9 to 10/15 around Dec. 17 and to 14/21 around Jan. 7, without new client installs.
  • Fusaka bundles 11–12 EIPs, including EIP‑7594 for PeerDAS and EIP‑7918 for bounded blob base fees, focusing on backend scalability and node efficiency.
  • A four‑week security contest offering up to $2 million runs Sept. 15–Oct. 13 on Sherlock, with early‑submission multipliers to surface bugs quickly.
  • Recent devnets flagged client stress and a ckzg library issue; Prysm behavior under high blob load is being investigated, a ckzg fix has shipped, and bundled client releases plus shadow forks are planned for the October rollout.
