Self Sovereign Identity
summary
Covers W3C Decentralized Identifiers (DIDs) as JSON documents that hold public keys and service endpoints, and W3C verifiable claims (signed JSON credentials) whose provenance is checked by resolving issuer keys — blockchain is used only to store DID anchors so users retain control. Shows two concrete flows: a government-issued name credential that authenticates to a service without sharing extra data, and an 18+ age credential shown to a cashier. Notes practical issues: key wallets, revocation and a social recovery pattern using trusted delegates.
