At 7:29 UTC today, on epoch 222464, the Pectra network upgrade went live on the Sepolia testnet. Unfortunately, an issue with Sepolia’s permissioned deposit contract prevented many execution layer clients from including transactions in blocks. The root cause was identified within minutes, and client teams immediately began working on a fix. This issue is due to Sepolia’s configuration and could not occur on the Ethereum mainnet. Around 14:00 UTC today, validators deployed a fix that restored the network to normal throughput. All Sepolia node operators must now upgrade their execution layer clients to the versions listed below to maintain network…
We’re excited to announce that the next Devconnect will be held in Buenos Aires, Argentina, from November 17th to the 22nd, 2025 at the iconic venue La Rural! This year, we are aiming for something bigger than just Devconnect: We want to support an effort that the local community has already started — bringing Argentina onchain. In Buenos Aires and Argentina, we have a city and country that have been leading adopters of Ethereum for many years. Devconnect Argentina is an opportunity for the whole Ethereum ecosystem to support that steady growth and to accelerate it even further, by helping…
The Mekong devnet was meant to be a playground for wallet developers to experiment with UX changes and for stakers to gain confidence in the upcoming Pectra changes. The Pectra network upgrade has been activated on the Ethereum Sepolia and Holesky testnets. These networks can now be used to test the Pectra upgrade features. In light of this, we’d like to announce the deprecation of the Mekong testnet on 7th March, 2025. Application and tooling developers are encouraged to use Sepolia to test applications, smart contracts, and other EVM functionality. Its permissioned validator set provides a stable test environment. Alternatively,…
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…
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! How the Scholars Program Works The Program will begin in late August with online…
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. tl;dr: Since the last Checkpoint, the Pectra upgrade shipped and core developers have maintained a heavy emphasis on keeping the next upgrade (Fusaka) lean to get PeerDAS, a scaling unlock, out the door. Fusaka testing is ongoing and developers are still optimistic about a 2025 release date. Proposals for the headlining feature of the upgrade following Fusaka (”Glamsterdam”, ~2026) are being solicited until…

It’s happening: Devconnect is coming to Buenos Aires, 17–22 November 2025. And we are bringing the first-ever Ethereum World’s Fair to the city. The Ethereum World’s Fair is for the Ethereum community and anyone curious about what Ethereum can do in the real world. We’re starting in Argentina, one of the most active crypto hubs, to show how Ethereum can bring a nation onchain with stablecoins, DeFi, decentralized identity, prediction markets, games, and more. Devconnect ARG will be different Main venue: We’re anchoring everything around La Rural, so the energy (and everyone) keeps flowing through the main hub. Ethereum World’s…
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.…
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…
