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…

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 4-6 weeks, depending on what’s happening in core development. See the previous update here. If you enjoy reading core development updates, you may also be keen to learn that Forkcast now publishes call summaries, chats and transcripts for each All Core Devs call, usually available within a couple hours of the call. tl;dr: The Fusaka upgrade is nearly out the door, Glamsterdam is ramping up, with its major features in implementation and minor features being decided on.…

Disclaimer: The following blog is a proposal from the Account Abstraction team. Content may not imply consensus views, and the EF is a broad organization that includes a healthy diversity of opinion across Protocol and beyond that together strengthen Ethereum. Since the early days of Ethereum, the promise has always been bold: a global, permissionless, censorship-resistant computing platform. Today, that promise is more alive than ever. Ethereum has scaled through rollups, where blockspace is abundant and transactions are cheap. The challenge now is not just throughput, but seamless user experience across that multichain horizon. What if all the L2s felt…

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,…

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…
