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…

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…

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,…

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…

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?…

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…
