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.

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.

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.

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 ecosystem can continue to thrive with everyone's participation.

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.
