DATA IS NOT AN ASSET TO EXPOSE. IT IS A RESPONSIBILITY TO PROTECT. “We really need to treat data as toxic waste by default.” Vitalik Buterin's statement at Devcon Mumbai raises an important question for Web3: Are we collecting and exposing more data than we actually need? I strongly agree with the perspective of Primus Labs @primus_labs: Collect less. Store less. Expose less. Privacy should not prevent data from being useful. It should allow sensitive information to be verified and used without revealing everything behind it. 1. Verification does not require full disclosure Imagine a DeFi platform checking whether a user meets certain financial requirements. The platform needs reliable evidence, but does it really need the user's complete financial history? A better approach is to verify the specific information required while keeping unrelated personal data private. This reduces unnecessary exposure and creates a more responsible relationship between users and applications. 2. How Primus contributes to this vision Primus Labs @primus_labs is building toward privacy-preserving data verification through technologies such as: - zkTLS: Helps verify the authenticity of information from Web2 sources while protecting the underlying data. - zkFHE: Enables computation on encrypted data, reducing the need to expose sensitive information during processing. These technologies address two important challenges: trusting external data and using sensitive information without unnecessarily revealing it. Their potential applications include DeFi, financial eligibility checks, private credentials, and institutional finance. 3. My perspective I believe the future of Web3 should not be measured by how much data platforms can collect. It should be measured by how much they can verify while exposing as little as possible. Vitalik reminds us to treat data as a responsibility. Primus is working toward the infrastructure that can help turn this principle into practical applications. The goal is not to hide useful information. It is to prove what matters without exposing everything else.
