Today, we are announcing a transition in the executive leadership team at the Ethereum Foundation. After extensive contributions to the Foundation’s mission and operations, Tomasz Stańczak has decided to step down from his role as Co-Executive Director. The Foundation’s Board has appointed Bastian Aue to serve as interim Co-Executive Director, effective immediately. Tomasz joined the management team during a critical period of growth and maturation for the Foundation. His strategic guidance helped expand our ability to reach out to broad groups of people and teams, and for the EF to understand businesses in the ecosystem more deeply. He also brought…

tl;dr I am stepping down from my co-ED role at the EF at the end of February 2026. Bastian Aue is taking over the co-ED role alongside Hsiao-Wei. The future is bright for builders, for Ethereum, for the EF, and for me. Future of Ethereum As competing ideas emerge and fail and the markets jump up and down, we have never been given too much certainty. The conviction about Ethereum that comes from a deep understanding of its technology, its governance, its meaning for the future, and the values we share will always make us converge intermittently, even when our…

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…

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…

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. Chain history By definition a blockchain is a chain of blocks starting at a specific genesis point. For Ethereum, that occurred on July 30, 2015. Each block includes information about…

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. How we can ship an L1 zkEVM in less than a year The fastest and safest way to ship an L1 zkEVM is to…

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…
