Vitalik Buterin Commits $45M in Ethereum to Open-Source Security and Privacy Tech

Ethereum co-founder Vitalik Buterin has committed 16,384 ETH—worth roughly $45 million—to support open-source security, privacy, and self-sovereignty technologies, as the Ethereum Foundation (EF) prepares for what he described as a period of “mild austerity.”

The announcement, shared on social media platform X, outlines both a strategic shift within the Ethereum Foundation and a personal financial commitment from Buterin to fund technologies he views as essential to the blockchain’s long-term mission.

According to Buterin, the Ethereum Foundation is entering this phase to balance two objectives over the coming years. The first is delivering on an aggressive roadmap that keeps it scalable and performant without compromising decentralization or sustainability. The second is ensuring the Foundation can sustain itself long-term while protecting Ethereum’s core goals, including user security, privacy, and self-sovereignty.

“In these five years, the Ethereum Foundation is entering a period of mild austerity, in order to be able to simultaneously meet two goals.”

As part of that shift, Buterin said he is personally stepping in to take responsibility for initiatives that might previously have been handled within the Foundation as special projects.

Why Buterin Is Personally Funding the Effort

Buterin said his focus is on supporting a “secure and verifiable full stack” of open-source software and hardware designed to protect both personal lives and public environments. The scope includes finance, communication tools, governance systems, blockchains, operating systems, secure hardware, and biotech, including applications related to personal and public health.

“We are seeking the existence of an open-source, secure and verifiable full stack of software and hardware that can protect both our personal lives and our public environments.”

He pointed to prior efforts that reflect this direction, including work on open silicon for security-critical applications, privacy-focused software incorporating zero-knowledge proofs, fully homomorphic encryption, and differential privacy, as well as donations to encrypted messaging platforms and environmental monitoring projects. Buterin also highlighted his preference for local-first and privacy-preserving software that users can independently verify.

‘Ethereum for People Who Need It’

While the funding is personal, Buterin stressed that Ethereum remains central to the broader vision of openness and verifiability. He said the Ethereum Foundation will continue focusing on the blockchain as foundational infrastructure for secure and decentralized systems.

“Ethereum itself is an indispensable part of the ‘full-stack openness and verifiability’ vision.”

Buterin drew a distinction between the blockchain’s mission and enterprise-driven adoption narratives, arguing that the priority should not be ubiquity, but usefulness for individuals and communities that rely on decentralized infrastructure for autonomy and safety.

“‘Ethereum everywhere’ is nice, but the primary priority is ‘Ethereum for people who need it’.”

He framed the initiative as a response to growing power concentration in technology and geopolitics, arguing that open and verifiable systems provide an alternative rooted in cooperation rather than domination.

“The tools to ensure your, and your community’s, autonomy and safety, as a basic right that belongs to everyone.”

The move reinforces Buterin’s long-standing emphasis on privacy, decentralization, and user sovereignty, while signalling renewed funding for the technical foundations needed to sustain those principles.
