Citadel Securities made a strategic investment at a $20 billion valuation. Institutional investors led the first tranche of funding. Kraken plans to grow across Latin America, APAC, and EMEA. Kraken is entering a new phase of global expansion after securing fresh capital that places the company at a valuation of $20 billion. The update outlined how this raise will support the firm’s plans for 2026 and strengthen its position across regulated markets, tokenized products, and institutional services. The company also linked the funding to its broader push into global regions, deeper derivatives activity, and new financial tools. The announcement signalled…

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…

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…

As previously announced, the Holešky testnet has reached its planned end-of-life date and will be sunset shortly. The vast majority of remaining validator nodes will be shut down 2 weeks after the Fusaka upgrade has finalized on Holešky. After this, Holešky will no longer be supported by client, testing or infrastructure teams. Following the launch of the Hoodi testnet in March 2025, infrastructure providers and staking operators have had the opportunity to migrate their testing operations. Background Holešky was launched in 2023 as Ethereum’s largest public testnet, designed specifically for testing staking infrastructure and validator operations at scale. The network…

Over the past few years, the Ethereum ecosystem has grown in depth, diversity, and maturity. Builders and communities worldwide have pushed the boundaries of what’s possible, creating new tools, protocols, and public goods that strengthen the network as a whole. As the ecosystem grows, our approach to supporting it must adapt as well. Today, we’re excited to share the next step in that journey: the Ecosystem Support Program’s (ESP) new grants program. This announcement builds on our earlier update, where we temporarily paused open grant applications to reassess our priorities and funding approach. During this time, we focused on designing…
