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…

Ethereum’s weekly All Core Developer calls are a lot to keep up with, so this “Checkpoint” series aims for high-level updates roughly every 4-5 weeks, depending on what’s happening in core development. See the previous update here. tl;dr: The Fusaka upgrade is nearly out the door and we’ll get a very good idea of “wen” this week with the first testnet upgrade going live just a few hours from this post. Glamsterdam headliners have been chosen: enshrined Proposer-Builder Separation and Block-level Access Lists, but small features still have about a week to be proposed for inclusion. Testing teams are looking…

Today we are proud to announce a new leadership structure for privacy-related efforts at the Ethereum Foundation: Igor Barinov joins as coordinator of Privacy @ EF, guiding strategy and alignment across privacy-focused efforts including PSE and more. Igor has over a decade of experience in the Ethereum ecosystem as founder of Blockscout, Gnosis Chain, and zkBob, and is a strong advocate for open-source and privacy. Andy Guzman will now serve as coordinator of the (PSE) team, taking over from Sam Richards and leading applied cryptography, research, and development. Andy has been with PSE/EF since 2022 and has led various key…

Privacy is the freedom to choose what you share, when you share it, and who you share it with. We all take this for granted in daily life: closing the door to a room, casting a secret ballot, or speaking privately with a friend. But online and onchain, these protections are often missing. Ethereum was created to be the foundation of digital trust, one that is worthy of civilizational scale. For that trust to remain credible, privacy must be part of its core, the EF, along with dozens of Ethereum teams focused on privacy, are proud to support this cause..…

The Funding Coordination team is excited to announce a joint initiative with Keyring Network that introduces a new approach to impact funding in the Ethereum ecosystem. Directly support privacy-focused developers Keyring’s zkVerified permissioned vaults on mainnet provide compliant and privacy-preserving access to DeFi lending markets. For the first two months, all protocol fees from Keyring’s zkVerified vaults will go to the legal defense funds of Roman Storm and Alexey Pertsev, the Tornado Cash developers currently on trial for publishing open-source code. This model ensures that the first users of a vault directly support the legal protection of privacy-focused developers. By…

The Ethereum Foundation has opened applications for the 2026 Internship Program: a paid, full-time opportunity to work directly with teams advancing the Ethereum protocol and ecosystem. Interns will join EF teams for 12 weeks over the summer, contributing to active R&D and ecosystem-oriented projects across a wide range of focus areas. The internship is open to candidates worldwide and can be completed remotely or from EF’s offices. A summer meetup will bring the cohort together to connect in person. The Goal Ethereum continues to evolve; each upgrade, research initiative, and experiment depends on people willing to dive into complex problems…

During Devconnect Buenos Aires, the Ethereum Foundation and Secureum TrustX brought together Ethereum security practitioners for Trillion Dollar Security Day, a focused event exploring what it would take to securely support a trillion-dollar Ethereum economy. The event brought together around eighty participants from across the Ethereum Security Ecosystem—spanning Infrastructure, Interoperability, Layer 1 & 2, Onchain, Offchain, Privacy, and Wallets—to assess the current security landscape, surface shared challenges, and identify concrete next steps across the stack. The discussions and outputs from this event contribute to the Ethereum Foundation’s ongoing One Trillion Dollar Security (1TS) initiative. Why a Trillion Dollar Security Day?…

The EF’s Academic Secretariat team is proud to announce the launch of the inaugural PhD Fellowship Program, a pioneering initiative aimed at empowering and expanding the frontiers of Ethereum-related academic research, by supporting Ethereum-related academic work led by PhD students. Round Scope The scope of this round includes work that is broadly relevant to students interested in pursuing research that are at the intersection of Institutional Design, Corporate Governance, Political Economic, Decentralized AI, and Ethereum. We are seeking proposals that align with the RFP topics listed on our webpage. We encourage researchers to use these RFPs as a starting point,…
