Sovereign data in Web3 refers to the concept of data ownership and control in decentralized systems where individuals have complete ownership and control over their personal data. In traditional Web2 systems, user data is stored on centralized servers owned and controlled by third-party companies, which can collect, analyze, and monetize user data without users’ consent.

In Web3, individuals can choose to share their data with specific applications or services on a case-by-case basis and also revoke access to their data at any time. This provides greater privacy and security for users, as well as more transparency and accountability in the use of personal data.
