We asked @VitalikButerin why he frames Ethereum's broader mission as building "sanctuary technologies" rather than open source or decentralization. His take: "We're in a less peaceful and less safe world than we were 10 or 15 years ago. 10 or 15 years ago, you were worried about banks getting bailouts and dollars inflating. 15 years later, the risk that the dollar is gonna go crazy is way more credible ... and there's much worse things happening to people than just having your currency inflated." "There is a vision of safety we're competing with. Basically, let's trust the uncle in the sky, and the uncle in the sky is going to figure everything out for us in exchange for taking away all of our privacy and all of our agency." "We want to be safe and at the same time empowered. We want something that continues to keep us in control and at the center in a way where we have agency." @sodofi_ @binji_x

The Ethereum Security QF round by @thedaofund is closing soon. Direct funding toward the projects making Ethereum safer. Explore the round with @jchaskin22 and @griffgreen.

Fireside Chat with @VitalikButerin , @ethereumJoseph & Lighter founder @vnovakovski ! We will discuss high performance applications, ZK rollups on Ethereum, roadmap for scaling, future of DeFi, and beyond. Monday, May 18th at 3PM UTC. Link in the replies. Don't miss it!

dAI <> @MiniMax_AI one of the leading teams in open source AI hosted us in Shanghai we discussed the infra we’re building for the open agent economy, multiagent AI, security grateful to meet head of eng @SkylerMiao7 - he shared impressive work on agent orchestration & feedback

Upgrading Finality - Edition 1 Check out the plan for bringing fast finality to Ethereum. Hosted on the the brand new and shiny EF Protocol Consensus website 😁 Lots of good stuff there!

this is fantastic! SafeLens brings offline + ERC-7730 clear signing to Safe. No more blind signing risks on important txs. Fully offline and local. Builders like you make the ecosystem stronger! @Th0rgal_

Live now: how Yearn automates DeFi strategies, the risks and trust assumptions involved, and what decentralized yield management looks like in practice With @jchaskin22, joined by @omgcorn of @yearnfi

0/ Clear signing is now live. An open standard to end blind signing, making human-readable transactions default. This effort brings a major UX and Security upgrade to transaction signing on Ethereum.

Tomorrow at 4pm UTC Ethereum Builders Live with @jchaskin22 and @omgcorn of @yearnfi. We’ll dive into how Yearn automates DeFi strategies, the risks and trust assumptions involved, and what decentralized yield management looks like in practice.

There's a new chapter starting for the Protocol cluster. We're welcoming new leads and coordinators, and continuing our work toward Glamsterdam, Hegotà, and the Strawmap. More in the blog below 👇

PRIVACY IS MORE THAN MONEY This is what the Kohaku project is, straight from its core contributors, @VitalikButerin and @ncsgy. TLDR: it is a serious attempt to rethink online safety and privacy across money, AI, and life. Let’s dive in.

1/ The Ethereum Audit Subsidy A joint initiative with audit providers to subsidize the cost of audits for Ethereum builders. Security audits are a best practice, yet expensive. The subsidy program makes audits accessible and strengthens the Ethereum ecosystem.

Today, several teams at the EF are launching a dedicated resource for Ethereum's post-quantum security effort. What started with early STARK-based signature aggregation research in 2018 has grown into a coordinated, multi-team effort, all open source. The Post-Quantum team and Cryptography teams, with help from the Protocol Architecture and Protocol Coordination teams, have been working on this body of work for 8+ years. At you'll find: - How PQ impacts each protocol layer - The full PQ roadmap ( - Open resources: repos, specs, papers, EIPs - FAQ: 14 questions across 5 categories, written by the PQ team - A 6-part lean Ethereum interview series (@zeroknowledgefm) - Interest form for the 2nd Annual PQ Research Retreat (Cambridge, UK, Oct 2026) - 10+ client teams are already building and shipping devnets weekly through PQ Interop. All the work is public and all of it is open.
