Decentralized Identifiers (DID)

In the realm of Self-Sovereign Identity (SSI), Decentralized Identifiers (DIDs) play a pivotal role in reshaping digital identity management. DIDs are unique, persistent identifiers created on decentralized networks, providing a secure foundation for user-controlled identity interactions. Complementing DIDs are DID Documents, which contain essential information such as public keys, authentication methods, and service endpoints associated with the DID. Importantly, DIDs can be resolved to their corresponding DID Documents, allowing for dynamic retrieval of key identity information. This dynamic duo, grounded in decentralization and cryptographic security, empowers individuals to independently own, control, and selectively share their identities across diverse platforms.

Example
Decentralized Identifier (DID)did:example:123456789abcdefghi
