We are excited to announce the Devconnect Scholars Program, as part of Devconnect ARG 2025! The Scholars Program will welcome 100 leaders who are expanding Ethereum's reach by connecting it to new communities, industries, and ideas. Scholars will co-learn and co-create, building bridges between Ethereum and other worlds. The 2025 cohort will include five categories: (1) Ethereum Community Organizers, (2) Legal & Public Sector Professionals, (3) Journalists, (4) Artists, and (5) Developers & Other Builders of any kind. Applications are now open, until Monday, June 30th!

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.

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 response, we must rethink our current approach to designing, developing and stewarding the protocol. This process of “shipping protocol” is messy, asking us to respond proactively

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” means a world where: Billions of individuals are each comfortable storing more than $1000 onchain, collectively amounting to trillions of dollars secured on Ethereum. Companies, institutions or governments

A new year means new momentum, and new grants! Take a look at the projects that received support in Q1 2025, listed below:

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 the full CVE report. N.B.: Part of this post requires some knowledge about elliptic curves (cryptography).

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.

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 into the global Ethereum community Learn directly from builders and researchers Showcase your ideas, research, or prototypes
