Primus: Why Applications Should Ask for Less Data Think about how many online services ask for personal information before allowing you to use them. Sometimes, an application only needs to confirm one thing, but users are required to share much more information than necessary. Imagine applying for an online service that only needs to confirm you're over 18. Why should you have to reveal your full date of birth, home address and other personal details? This is where selective disclosure becomes important. What is selective disclosure? Selective disclosure allows users to prove specific information without exposing everything connected to their identity or account. For example, instead of sharing your entire educational profile, you could prove that you completed a particular course. The application gets the information it needs without collecting unrelated personal details. Where does Primus fit in? Primus uses zkTLS to help users generate cryptographic proofs about information retrieved from supported HTTPS websites. This can allow users to prove selected claims from external platforms without simply handing over screenshots or exposing their entire accounts. Imagine an employer who wants to confirm that you completed a professional course on an online learning platform. Instead of requesting access to your full account, you could potentially provide a proof of that specific achievement. The employer can verify the claim without needing all your other account information. Why does this matter? This approach could be useful across different sectors: - Digital identity: Prove specific credentials without exposing unnecessary personal details. - DeFi: Share relevant financial information without revealing an entire account. - Education: Verify certificates and completed courses. - Online services: Reduce unnecessary collection of user information. Of course, the amount of information revealed depends on how each proof is designed and what the receiving application requires. My takeaway Privacy shouldn't mean making verification impossible. Applications should be able to confirm what they need without demanding access to everything a user has. Primus is helping make this possible through verifiable web data and privacy-preserving proofs. The goal is simple: prove what matters, reveal less, and give users more control over their information. @primus_labs
