Vitalik Buterin Releases Ethereum Foundation Mandate Positioning ETH as Sanctuary Technology for the Censorship-Resistant Web

Vitalik Buterin published the new Ethereum Foundation mandate on March 13, framing the organization’s purpose in terms that go considerably beyond blockchain infrastructure.

Ethereum’s role, as defined in the document, is to serve as a sanctuary technology, preserving technological self-sovereignty, enabling cooperation without coercion or domination, and ensuring that no single person, organization, or ideology can achieve total victory in cyberspace. The mandate is as much a philosophical declaration as an operational document.

Buterin was direct that the contents should not surprise anyone who has been following the foundation’s direction over recent months. The clarification, he wrote, is nevertheless worth making. The document establishes what the Ethereum Foundation is, what it is not, and where it intends to focus its resources and expertise going forward.

Central to the mandate is an acronym Buterin has used in prior public writing: CROPS, standing for censorship and capture resistance, open source, privacy, and security. The foundation commits to prioritizing these properties at both the protocol layer and the application layer, in user-facing tools and access infrastructure as much as in the underlying technical architecture.

What the Foundation Will and Will Not Do

The mandate draws a careful distinction between three categories of activity. Things the foundation does because they serve Ethereum’s core values. Things it does not do because it finds them uninteresting or harmful by its value framework. And things it does not do because while they may be useful, they fall outside its defined role. That third category is significant. It signals that the EF is deliberately narrowing its scope to areas where its specific expertise and mandate add value, rather than attempting to be the organizing force for every direction the Ethereum ecosystem takes.

At the protocol layer, the focus is on decentralization, verifiability, inclusion guarantees, liveness, security, and privacy. Capabilities such as layer-1 scaling, account abstraction, and in-protocol aggregation are valued specifically because they enable users to better access Ethereum’s CROPS properties and reduce dependence on intermediaries that would otherwise dilute those properties as they pass through the stack. The foundation also introduces what Buterin calls the walkaway test: the protocol must be designed so that it remains viable if the EF were to walk away, a standard that prioritizes durable decentralization over convenience-driven centralization around any single steward including the foundation itself.

The Application Layer and the Zero Option

At the application layer, the mandate introduces the concept of the zero option, a term for user experiences that prioritize security and privacy, minimize intermediary dependence, and respect user agency above all else. The EF intends to develop this as its center of expertise, not as competition to the broader Ethereum ecosystem that builds products optimized for mainstream adoption and accessibility, but as complementary to it. Tools built within the EF can be adopted by anyone, in whole or in part, and even partial adoption that improves a user’s security, privacy, or agency is considered a positive outcome.

Buterin acknowledges the tension in this design philosophy directly. The mandate does not advocate for leaving users vulnerable to losing their savings through a misclick on a confirmation screen. It argues that user protection must be built on a philosophical baseline of empowering the user rather than empowering centralized organizations that claim to act in the user’s name. That design space, caring about user safety while remaining committed to user agency and freedom, is described as underserved not just in crypto but across the technology industry broadly. Ethereum, in this framing, is a platform for demonstrating that this combination is achievable.

A Broader Community Than Ethereum Alone

The mandate’s final framing shift is the one with the longest-term implications. Buterin calls on the foundation and the community to see themselves not solely as the Ethereum community but as maintainers of the Ethereum tool within what he variously calls the CROPS community, the sanctuary tech community, or the decentralized and censorship-resistant technology movement more broadly. That positioning opens the door to alliances and collaborations with people and projects that share Ethereum’s values but have no particular attachment to its specific technology stack.

This framing connects directly to a thread Buterin has been developing in recent public writing, including his reflections following the Real World Crypto conference where he concluded that Ethereum’s most fundamental contribution, before smart contracts and before payments, is its function as a censorship-resistant public bulletin board. The new mandate institutionalizes that perspective, making it the organizing principle of the Ethereum Foundation’s work rather than a personal observation from its co-founder.

The document closes with Buterin’s characterization of the EF as one steward of Ethereum, not the sole one, and with an encouragement to read the full mandate including its concrete examples of how the foundation intends to navigate the nuances of these commitments. The doubling down, as he frames it, is not on Ethereum’s market position or its competitive standing against other blockchains. It is on the specific set of properties that make Ethereum worth building on in the first place.
