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. !we-are-here.png

From grassroots gatherings to breakthrough projects, here's what we supported in Q2 2025! Scroll down to explore the work happening across the Ethereum ecosystem:

Thanks to Kevaundray Wedderburn, Alex Stokes, Tim Beiko, Mary Maller, Alexander Hicks, George Kadianakis, Dankrad Feist, and Justin Drake for feedback and review. Ethereum is going all in on ZK. Eventually we expect to migrate to using ZK proofs at all levels of the stack, from consensus layer signature aggregation to onchain privacy with client side proving, and upgrade the protocol to be simpler and more zk-friendly. But the first step will be an L1 zkEVM.

Ethereum stands at a pivotal moment. Interest in Ethereum has expanded beyond technologists and enthusiasts, bringing enterprises, governments, and everyday users who seek practical solutions and tangible benefits. The Ethereum ecosystem is adapting to meet these needs, and the Ethereum Foundation is ready to play its part. As outlined in the Ethereum Foundation’s recent vision statement, we have two key goals: Maximizing the number of people who (directly or indirectly) use Ethereum, in such a way that they benefit from Ethereum’s underlying values. Maximizing the resilience of Ethereum’s technical and social infrastructure. Ecosystem Development (EcoDev) refers to teams that help achieve these goals at an ecosystem or social level, rather than a technology level. These teams help remove bottlenecks to real-world use, help users get onboarded to

As of today, all Ethereum execution clients support partial history expiry in accordance with EIP-4444. While work on full, rolling history expiry is ongoing, users can expect to reduce the disk space required for an Ethereum node by 300-500 GB by removing the block data prior to the Merge. This will allow a node to fit comfortably on a 2 TB disk. See below for information on each specific client.

Ethereum’s weekly All Core Developer calls are a lot to keep up with, so this "Checkpoint" series aims for high-level updates depending on what’s happening in core development. See the previous update here. This is a special edition of the series! Kicking off Berlin Blockchain Week, ethereum core devs and researchers got together for an interop hacking week to make progress both on long-term research directions and short-term implementation of the Fusaka upgrade and gas limit increases. Two of these days solicited feedback on longer-term research directions from L2 and zk teams. The most recent in-person interop was in Bangkok prior to Devcon but previous interops focused on Pectra & PeerDAS (Nyota), Shapella & Protodanksharding (Edelweiss), the Merge (Amphora), and Eth2 (Ontario)

This is an update from the Next Billion Fellowship Program. Applications are rolling and open for cohort 6 beginning in October 2025. Individuals interacting with an application have a user experience. Collectives interacting with a protocol have a world experience. There are many worlds that the Ethereum protocol touches; places where organizations, communities, or institutions experience trust through coordination. The Next Billion Fellowship is a program to support individuals working on new use cases and improving trust experience within the world computer. The stories of a global protocol are as diverse and varied as the humans that use it. In this update five Next Billion Alumni share stories about their Fellowship experience, and four new Next Billion Fellows are introduced. <div style="

We’re thrilled to announce that internship applications are now open for the first-ever Ethereum Season of Internships! The Ethereum Season of Internships is a collection of paid, fully-remote summer internships offered across the Ethereum ecosystem. It is designed to help establish more paths for the next generation of contributors to connect with Ethereum projects and apply their skills – whether in development, research, design, marketing, operations, or more. Our long-term goal is to make Ethereum an even more welcoming place for new talents. Over the past few weeks, 19 teams from across the ecosystem have created over 30 internship opportunities. Each position is paid, remote-friendly, and designed to offer real-world experience and mentorship. Whether you’re a developer, researcher, designer, or community builder, this is your invitation to
