Today, we are announcing a transition in the executive leadership team at the Ethereum Foundation. After extensive contributions to the Foundation’s mission and operations, Tomasz Stańczak has decided to step down from his role as Co-Executive Director. The Foundation’s Board has appointed Bastian Aue to serve as interim Co-Executive Director, effective immediately. Tomasz joined the management team during a critical period of growth and maturation for the Foundation. His strategic guidance helped expand our ability to reach out to broad groups of people and teams, and for the EF to understand businesses in the ecosystem more deeply. He also brought…
tl;dr I am stepping down from my co-ED role at the EF at the end of February 2026. Bastian Aue is taking over the co-ED role alongside Hsiao-Wei. The future is bright for builders, for Ethereum, for the EF, and for me. Future of Ethereum As competing ideas emerge and fail and the markets jump up and down, we have never been given too much certainty. The conviction about Ethereum that comes from a deep understanding of its technology, its governance, its meaning for the future, and the values we share will always make us converge intermittently, even when our…
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…
tl;dr: Over the last couple of days, some L2s noticed that their deployments on Sepolia didn’t work properly anymore. This is due to EIP-7594 which changes the format for proofs. In anticipation of Fusaka, we urge all blob originators to update their software to create Cell Proofs instead of blob proofs. Background One underdiscussed aspect of EIP-7594 (PeerDAS) is that it changes the format for proofs from blob proofs to cell proofs. This allows for downloading a specific part of the blob instead of the whole blob for data availability sampling. This change might break user applications that send blob…
Starting with the upcoming Fusaka hard fork, EIP-7825 introduces a per-transaction gas limit cap of 2²⁴ (≈ 16.78 million gas). This change is already live on Holesky and Sepolia, and will activate on mainnet with Fusaka. Developers and users who rely on very large transactions should verify that their contracts and transaction builders conform to the new cap. Background As Ethereum scales to higher block gas limits and prepares for parallel execution (e.g. EIP-7928 in Glamsterdam), the Fusaka fork introduces a per-transaction gas limit cap. Previously, a single transaction could consume the entire block gas limit (~45 million gas), creating…
Over the past few years, the Ethereum ecosystem has grown in depth, diversity, and maturity. Builders and communities worldwide have pushed the boundaries of what’s possible, creating new tools, protocols, and public goods that strengthen the network as a whole. As the ecosystem grows, our approach to supporting it must adapt as well. Today, we’re excited to share the next step in that journey: the Ecosystem Support Program’s (ESP) new grants program. 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…
In two weeks, we open the doors to the first-ever Ethereum World’s Fair at La Rural in Buenos Aires. This year isn’t about someday. It’s about now. On Ethereum today you can pay, play, vote, save, borrow, lend, and chat, all onchain — and at Devconnect you’ll experience that shift hands-on, IRL.Buenos Aires is the right backdrop for this moment: a city where crypto is part of daily life and where builders are ready to show what’s live. Below is your guide to what’s inside the fairgrounds, how to plan your week, and what to do before you arrive. Inside…
Fusaka follows this year’s Pectra upgrade, representing a major step forward in Ethereum’s scaling roadmap that improves L1 performance, increases blob throughput, and enhances user experience. The Fusaka network upgrade is scheduled to activate on the Ethereum mainnet at slot 13,164,544 (December 3, 2025, 21:49:11 UTC). 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. See the activation table below for further details. The Fusaka mainnet client releases are listed below. Fusaka Overview Fusaka’s headlining feature is PeerDAS (Peer…
