Notes from the Ethereum Foundation's Protocol Security team on running coordinated AI agents against real protocol code, including how we organize the work, what holds up under scrutiny, and what client teams and security researchers can take from it. This post stands on its own; later posts will go deeper on individual clients.

Current global shifts clearly signal a critical need for shared, neutral digital public infrastructure outside the control of any single centralized actor. As a public, programmable network designed to operate without reliance on any single party, Ethereum was built to address precisely these needs. Today, the Ethereum Foundation Global Policy Strategy (GPS) team is publishing "Ethereum for Governments and Institutions", a guide for public sector and institutional leaders facing policy and deployment decisions. The report is a non-technical primer covering how Ethereum works, how it is governed, how it compares with perceived alternatives, and where it is already being deployed. This post introduces the report and answers the core questions that motivated its development: why digital infrastructure needs to be neutral and why Ethereum is

Today, the EF is changing shape, concluding a months-long process of reorganization as part of the implementation of the Mandate and the Treasury Management Policy. We come out of this process with the structure, activities, and people necessary for execution on the critical tasks ahead of us, but also with 54 fewer colleagues, roughly 20% of the EF, many of whom will be finding ways to contribute to Ethereum from outside the EF in the coming weeks. This post provides a brief introduction to the new structure and details on how we are supporting the people who are leaving.

An Ethereum Working Group consisting of wallet developers, security firms and the Ethereum Foundation’s Trillion Dollar Security Initiative today launched an open standard designed to end blind signing — a structural flaw that has contributed to billions in user losses, including the Bybit hack. Ethereum Foundation’s Trillion Dollar Security Initiative is taking an active role as a credibly neutral steward of the Clear Signing registry. Across major exploits in crypto and blockchain applications, the final step often isn’t a bug in code, but a user approving a transaction. Even when phishing or an infrastructure compromise initiates the breach, the last step is typically a confirmation the user cannot meaningfully understand. Approving a transaction is meant to be the last line of defense when exercising control over

A semi-regular gathering of Ethereum core devs from various client teams, or interop, recently took place in Svalbard, Norway. Over the week-long event, teams focused on hardening and preparation for the next upgrade, Glamsterdam. Several important milestones came out of the week, including: 200M gas limit floor established: Credible post-Glamsterdam target derived from convergence of ePBS, BAL optimizations, and EIP-8037 repricing ePBS stabilized: Multi-client Glamsterdam-devnet running with external builders pipeline tested end-to-end across nearly all clients EIP-8037 finalized: Fixed cost\per\state\_byte adopted; full repricing numbers delivered by Friday on bal-devnet-6 Hegotá groundwork laid: FOCIL prototypes are functional; native AA requirements were scoped; the multi-client devnet is the immediate next step The interop also marked the start of a leadership

This past week, just over 100 Ethereum core contributors gathered above the Arctic Circle — in Longyearbyen, Svalbard — for the Soldøgn Interop: a week of intense work on the Glamsterdam network upgrade. Soldøgn followed last year's Berlinterop, but returned to the format used by Amphora 🏺, Edelweiss 🏔️, and Nyota ✨: a single-track week of focused, multi-client progress toward a specific upgrade — in this case, hardening Glamsterdam. By Friday, the group had delivered on its three core goals: alignment on a post-Glamsterdam gas limit floor of 200M, stable ePBS implementations running with external builders, and final EIP-8037 repricing numbers locked in. Meaningful progress was also made on Hegotá features like FOCIL and native account abstraction, as well as a slew of other topics.

TL;DR: 📝 Applications for EPF7 are open until May 13 🔎 Review the program details for EPF7 🎙️ An introductory town hall will be held on May 6 at 1500 UTC We are excited to announce that applications are now open for the seventh cohort of the Ethereum Protocol Fellowship (EPF7). EPF provides a pathway for aspiring protocol developers to make meaningful contributions to Ethereum. In each cohort, a diverse group is assembled to work toward advancing Ethereum's roadmap focused on the core properties that define Ethereum; censorship resistance, open source, privacy, and security. This includes the development of client implementations, testing and specifications, and engaging with the latest core protocol research. With an overarching goal of finding placement for fellows in R&D teams working on core

Q1 2026 continued our focus on strengthening Ethereum’s foundations, with sustained investment in core domains like cryptography, zero-knowledge proofs, security, and protocol research. See the list below of the projects and ecosystem efforts we supported this quarter as builders advance critical infrastructure, tools, and research across the network.
