Vitalik Buterin Raises Data Privacy Alarm: Calls for New Tools to Protect Ethereum Users
2025-04-15
Vitalik Buterin, the visionary co-founder of Ethereum, is sounding the alarm on one of the most pressing issues of our time—data privacy.
In a heartfelt and thought-provoking blog post titled “Why I Support Privacy,” Buterin explains why the need for privacy tools in blockchain is more urgent than ever.
With surveillance, data abuse, and centralization creeping into the very fabric of the internet, Buterin believes it’s time for the crypto community to shift gears and seriously address privacy protection.
Buterin Criticizes Centralized Platforms
In this latest writing, Buterin openly criticizes the growing reliance on centralized platforms that quietly gather personal data.
He points out that while many people worry about centralized infrastructure being used to deplatform or censor users, the far more subtle—and dangerous—threat lies in silent data collection.
This issue, according to him, is now being amplified by the rise of artificial intelligence, which makes it easier than ever to gather, analyze, and exploit massive amounts of user data.
“Privacy gives you the freedom to live your life in a way that best suits your personal goals and needs,” Buterin writes, emphasizing that data protection is not a luxury—it’s a right.

The Myth of Transparency: Buterin Sets the Record Straight
In a surprising twist, Vitalik Buterin also challenges the long-held assumption that full transparency leads to better governance.
He argues that while the original intentions behind transparency may have been noble—such as promoting accountability—the reality has turned out differently.
Societies haven’t become more tolerant or more ethical. Instead, the erosion of personal privacy has left individuals vulnerable to intrusion, judgment, and sometimes even harm.
Buterin also shares his personal experiences, highlighting how his high-profile status has made him a target for invasive scrutiny.
Through this lens, he argues that data privacy must not be seen as something to be traded off in the name of security or transparency. It must be preserved for the benefit of all—especially those in unique or sensitive situations.

The Ethereum Ecosystem Needs a Privacy Upgrade
As one of the most influential figures in blockchain, Vitalik Buterin is now shifting his focus towards building better privacy solutions within the Ethereum network.
He admits that for a long time, the industry pushed privacy concerns aside because there were simply no good tools available. But that’s changing now—thanks to technological advances like ZK-SNARKs and Fully Homomorphic Encryption (FHE).
ZK-SNARKs (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge) allow users to prove that something is true without revealing any additional information. It’s like proving you’re over 18 without showing your actual date of birth.
Meanwhile, FHE enables computations on encrypted data—meaning data can remain private even while being processed.

Tools for the Future
In his blog, Buterin outlines several privacy-centric tools that could change the future of Web3:
- ZK Proof of Personhood: Verifying someone is a unique human without revealing identity.
- On-Device Anti-Fraud Scanning: Preventing scams without sending data to central servers.
- Privacy Pools: Allowing financial transactions to stay anonymous but still verifiable.
- Proof of Provenance: Tracking items' authenticity without exposing personal data.
For Buterin, these tools strike a delicate balance—preserving the integrity and security of the Ethereum blockchain while also protecting individual freedoms.
He sees them as key innovations that can steer the crypto industry away from centralized control and back to its roots of empowerment, decentralization, and privacy.
