Today, we are excited to announce the start of the Fusaka audit contest, co-sponsored by Gnosis and Lido, hosted on Sherlock, and running for four weeks from September 15th. The goal is simple: maximize scrutiny of the Fusaka upgrade and surface vulnerabilities before they can impact the network. To raise the stakes, valid findings reported in the first week have a 2x multiplier applied to their points rewarded, and those in the second week have a 1.5x multiplier. To help security researchers, we’ve prepared a Fusaka auditor guide. We’re grateful to Gnosis for contributing 100,000 USD and Lido for contributing…

Fusaka follows this year’s Pectra upgrade, representing a major step forward in Ethereum’s scaling roadmap by introducing PeerDAS and key improvements that enhance blob throughput, L1 performance, and user experience. This post announces the testnet activation schedule for the first three testnets, beginning with Holesky at slot 5,283,840 (October 1, 2025, 08:48:00 UTC). See the activation table below for the complete Sepolia and Hoodi timeline. Fusaka also introduces Blob Parameter Only (BPO) forks to safely scale blob throughput after PeerDAS activation. These are minimal, config-only upgrades that adjust the blob target/max and fee update fraction. The Fusaka testnet client releases…

This announcement builds on our earlier update, where we temporarily paused open grant applications to reassess our priorities and funding approach. During this time, we focused on designing…
