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…

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 Core developers are focused on getting Fusaka out the door and choosing the headline feature(s) for the following upgrade, Glamsterdam. Discussions are ongoing and stakeholder feedback is being solicited. Gas limit increases and history expiry have both been delivered! Fusaka Fusaka will deliver cheaper L2 transactions and more data availability. Developers were already fast-tracking the upgrade to ship PeerDAS and it’s now…

On July 30, 2025, the Ethereum community marked a major milestone: ten years since the Ethereum’s genesis block and mainnet launch. What began as a whitepaper has evolved into a decentralized platform now powering thousands of applications, tools, and communities around the world. The Celebration To commemorate the occasion, over 100 ecosystem-led events took place across 6 continents. These gatherings spanned meetups, workshops, art shows, and hackathons, all organized by members of the Ethereum community. The Ethereum Foundation hosted a livestream event to welcome in the next decade. The livestream featured a discussion with Ethereum co-founders Vitalik Buterin and Joseph…

Yesterday Ethereum turned 10. Today, lean Ethereum is unveiled as a vision—and personal mission—for the next 10 years. We stand at the dawn of a new era. Millions of TPS. Quantum adversaries. How does Ethereum marry extreme performance with uncompromising security and decentralization? TLDR: next-generation cryptography is central to winning both offense and defense. Disclaimer: This is a Drake take™ aimed at a broad audience. A technical deep dive into hash-based post-quantum signatures and SNARKs will follow. A healthy diversity of views across Protocol, the EF, and the broader Ethereum community is expected and welcome. It strengthens us. defense—fort mode…

Today, we are excited to announce the start of the Fusaka audit contest, co-sponsored by Gnosis and Lido, hosted on Sherlock, and running for four weeks from September 15th. The goal is simple: maximize scrutiny of the Fusaka upgrade and surface vulnerabilities before they can impact the network. To raise the stakes, valid findings reported in the first week have a 2x multiplier applied to their points rewarded, and those in the second week have a 1.5x multiplier. To help security researchers, we’ve prepared a Fusaka auditor guide. We’re grateful to Gnosis for contributing 100,000 USD and Lido for contributing…

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…

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…
