Hi! This is Hsiao-Wei and Tomasz co-writing this blog post. We’ve now been in our new Co-Executive Director roles for almost a month. The honeymoon is over, it’s time to get moving. A Moment of Transition and Opportunity Ethereum has always been a journey: a constantly evolving ecosystem powered by people who believe in building a more open and decentralized world. While the Ethereum Foundation (EF) may be a decade old, it remains willing to reinvent itself. This year, EF embraced a new leadership model with dual Executive Directors. This design brings diverse and complementary perspectives, enhancing our ability to…

Ethereum’s strength lies in its decentralization — not just technically, but socially and structurally. This blog articulates the EF’s vision, its role, and priorities as one of the ecosystem’s stewards. We use this moment as an opportunity to restate our vision, principles and values which we continue to uphold as we welcome the new management team. These priorities are not a rigid plan and are reflected in the strategies described by EF’s Co-EDs. By defining our approach and focus, we also aim to clarify where we direct our efforts — and where we intentionally step back — so that the…

The recent appointments of the two Co-Executive Directors and President are part of a broader effort to strengthen the Ethereum Foundation, and this structure is designed to ensure our vision, strategic and balanced execution, technical direction, and ecosystem development. This blog is intended to clarify the structure of the management team and the board. New Management (Strategic & Operational Execution) EF’s Co-EDs will lead and execute together with other management members. You can expect to hear from members of EF management regularly on their plans, decisions, and other new changes. Hsiao-Wei Wang, Co-Executive DirectorTomasz K.

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 calls, depending on what’s happening in core development. See the previous update here. tl;dr: The past month centered on locking in the scope of the Fusaka upgrade and final Pectra deployment details. The Pectra upgrade ships on mainnet in just about a week, after which focus will shift to Fusaka testing and deciding what goes into the Glamsterdam upgrade (in other words, the ”scope” of the upgrade). A new All Core Developer (”ACD”) call structure will…

Are you part of a university blockchain club eager to dive deeper into the world of Ethereum? We want to connect with you! The Ethereum Foundation is sponsoring a global University Tour in partnership with BuidlGuidl, designed to activate student communities and grow the next generation of Ethereum builders. This tour includes: 🧑‍💻 Virtual sessions with Ethereum educators and builders🏫 In-person workshops on campuses across the globe🏆 A cross-university club competition, culminating in a live finals at Devconnect 2025 Whether your club is just getting started or already deeply embedded in the Ethereum ecosystem, this is your chance to: Plug…

Every year, the Ethereum ecosystem welcomes thousands of builders through community events, hackathons, courses, bootcamps, and campus clubs. However, many newcomers struggle to remain engaged, as they face challenges securing structured early-career opportunities. The Ethereum Season of Internships directly addresses this retention gap by creating a coordinated collection of internship opportunities across the ecosystem. What is the Ethereum Season of Internships? The Ethereum Season of Internships offers a coordinated collection of paid, fully remote summer internships across the Ethereum ecosystem. This initiative creates pathways for the next generation of contributors to connect with Ethereum projects and apply their diverse skills…

Thanks to Marius Van Der Wijden for creating the test case and statetest, and for helping the Besu team confirm the issue. Also, kudos to the Besu team, the EF security team, and Kevaundray Wedderburn. Additionally, thanks to Yuxiang Qiu, Justin Traglia, Marius Van Der Wijden, Benedikt Wagner, and Kevaundray Wedderburn for proofreading. If you have any other questions/comments, find me on twitter at @asanso tl;dr: Besu Ethereum execution client version 25.2.2 suffered from a consensus issue related to the EIP-196/EIP-197 precompiled contract handling for the elliptic curve alt_bn128 (a.k.a. bn254). The issue was fixed in release 25.3.0. Here is…

Ethereum is the most secure blockchain ecosystem. This is the result of 10 years of progress and iteration across every level of Ethereum’s technology stack, from wallet UX to developer tooling to consensus protocol security. But being the most secure platform in the crypto ecosystem isn’t enough. Ethereum’s ambition is far greater: to be civilization-scale infrastructure that securely underpins the internet and global economy, surpassing the safety and trustworthiness of the world’s legacy systems. Today we are announcing the Trillion Dollar Security initiative, an ecosystem-wide effort to upgrade Ethereum’s security to help bring the world onchain. Reaching “Trillion Dollar security”…

Ethereum stands at the edge of major breakthroughs. zkEVMs have rapidly accelerated, enabling us to rearchitect L1 to simultaneously support scale, verifiability, security and censorship-resistance. L2s are hardening, meeting users where they are, and eager to double down on using Ethereum as their root of trust. In short, the world is ready for the world computer. These significant innovations both unlock massive benefits for our users and will allow us to onboard many, many more. The stakes are high: This moment may be Ethereum’s best shot at deploying not only our technology, but our values, at planetary scale. As a…
