World’s Fairs have historically showcased the biggest innovations of their time like telephones, televisions, photography, and light bulbs. In this spirit, Ethereum gets its own World’s Fair this November in Buenos Aires. A week where the ecosystem doesn’t just talk about innovation, but showcases what’s being built now, and what’s next. We’re creating a space to see, touch, and experience the frontier of technology. A World’s Fair that showcases what Ethereum can do today. The eight districts of the Ethereum World’s Fair Just as Nikola Tesla’s electricity system lit up Chicago’s World’s Fair in 1893, when most people still used…

Fusaka follows this year’s Pectra upgrade, representing a major step forward in Ethereum’s scaling roadmap by introducing PeerDAS and key improvements that enhance blob throughput, L1 performance, and user experience. This post announces the testnet activation schedule for the first three testnets, beginning with Holesky at slot 5,283,840 (October 1, 2025, 08:48:00 UTC). See the activation table below for the complete Sepolia and Hoodi timeline. Fusaka also introduces Blob Parameter Only (BPO) forks to safely scale blob throughput after PeerDAS activation. These are minimal, config-only upgrades that adjust the blob target/max and fee update fraction. The Fusaka testnet client releases…

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: The Fusaka upgrade is nearly out the door and we’ll get a very good idea of “wen” this week with the first testnet upgrade going live just a few hours from this post. Glamsterdam headliners have been chosen: enshrined Proposer-Builder Separation and Block-level Access Lists, but small features still have about a week to be proposed for inclusion. Testing teams are looking…

Today we are proud to announce a new leadership structure for privacy-related efforts at the Ethereum Foundation: Igor Barinov joins as coordinator of Privacy @ EF, guiding strategy and alignment across privacy-focused efforts including PSE and more. Igor has over a decade of experience in the Ethereum ecosystem as founder of Blockscout, Gnosis Chain, and zkBob, and is a strong advocate for open-source and privacy. Andy Guzman will now serve as coordinator of the (PSE) team, taking over from Sam Richards and leading applied cryptography, research, and development. Andy has been with PSE/EF since 2022 and has led various key…

Privacy is the freedom to choose what you share, when you share it, and who you share it with. We all take this for granted in daily life: closing the door to a room, casting a secret ballot, or speaking privately with a friend. But online and onchain, these protections are often missing. Ethereum was created to be the foundation of digital trust, one that is worthy of civilizational scale. For that trust to remain credible, privacy must be part of its core, the EF, along with dozens of Ethereum teams focused on privacy, are proud to support this cause..…

Disclaimer: The following blog is a proposal from the Stateless Consensus team. Content may not imply consensus views, and the EF is a broad organization that includes a healthy diversity of opinion across Protocol and beyond that together strengthen Ethereum. Special thanks to Ladislaus von Daniels and Marius van der Wijden for reviewing this article. Ethereum has grown from a small experimental network into a critical piece of global infrastructure. Every day it settles billions of dollars in value, coordinates thousands of applications, and anchors an entire ecosystem of L2s. All of this ultimately relies on a single underlying component:…

Thanks to Arantxa Zapico, Benedikt Wagner, and Dmitry Khovratovich from the EF cryptography team for their contributions, and to Ladislaus, Kev, Alex, and Marius for the careful review and feedback. The zkEVM ecosystem has been sprinting for a year. And it worked! We crossed the finish line for real-time proving! Now comes the next phase: building something mainnet-grade. From speed to security In July, we published a north-star definition for realtime proving. Nine months later, the ecosystem crushed it: proving latency dropped from 16 minutes to 16 seconds, costs collapsed 45×, and zkVMs now prove 99% of all Ethereum blocks…

Fusaka shipped PeerDAS in addition to a myriad of minor features and Glamsterdam’s major features will include Block-level Access Lists and enshrined Proposer-Builder Separation. Now we begin outlining the subsequent upgrade: Hegotá. Timeline Jan 8th – Feb 4th: Headliner proposals (EthMag) Feb 5th – Feb 26th*: Headliner discussion & finalization (ACD calls) 30-day window to follow: Non-headliner EIP proposals (Hegota Meta EIP) *subject to change Headliner proposals Hegota’s major features (”headliners”) will be chosen first. These features, presented as EIPs, can be submitted on the Ethereum Magicians forum beginning January 8th, using a template that will be posted in the…

Devcon, the Ethereum community’s annual global gathering for builders, will take place from 3-6 November 2026 at the JIO World Center in Mumbai, India. This Devcon 8 update is not a full vision, but will help organizers and the wider ecosystem plan. More details on programming, tracks, and participation will follow in the coming months. Why India, why Mumbai India was selected as the next host location based on the scale and rapid growth of its developer ecosystem, rising local adoption, and strong grassroots Ethereum communities. India has 17M+ developers on GitHubIt has been the largest source of new crypto…

Platform is a new team inside the EF with one goal: Deliver the strongest possible Ethereum platform, where L1 and L2s are best positioned to support users, apps, and all organizations building on Ethereum. This requires improving the L1 <> L2 relationship, so that we grow as a mutually reinforcing system across each layer. Since the rollup-centric roadmap was first proposed 5 years ago, an ecosystem of chains has grown up around the Ethereum L1. The early mental model of rollups has given way to a network of differentiated L2s, each with distinct and valuable economies, extending Ethereum’s core properties…
