1. What Is Self-Sovereign Identity
Self-sovereign identity (SSI) is a model where individuals own and control their digital identity — data, credentials, and reputation — without relying on a central authority, using decentralized identifiers and verifiable credentials.
2. How It Works
Users hold identity data in wallets as verifiable credentials issued by trusted parties. They present proofs (often ZK-based) to verifiers, revealing only what's needed. Decentralized identifiers (DIDs) are self-generated and portable. No central registry stores or controls the identity; users decide what to share and with whom.
3. Why It Matters
SSI reverses the platform-controlled identity model — reducing data silos, enabling privacy-preserving verification, and giving users portable reputation. It underpins Web3 identity, digital wallets, and compliant but private KYC. Adoption challenges include issuer trust and interoperability standards.
4. Key Facts
- W3C standards: DIDs and Verifiable Credentials
- ZK proofs enable selective disclosure
- SSI wallets store credentials, not just keys
- Contrasts with platform or government-issued identities
