Decentralized Identifiers (DIDs) are a key building block of the emerging Self-Sovereign Identity (SSI) ecosystem. They are a new kind of identifier: Persistent, cryptographically verifiable, resolvable, and of course decentralized, i.e. independent of any central authority or intermediary. In this talk we will explore how DIDs function internally, how they can get registered and resolved, and how they can be used for authentication purposes (DID Auth). The talk will also give an update on the current state of standardization and implementation of DIDs.
