Carbon Decentralized Identifiers

Decentralized Identifiers (DIDs) are a W3C standard for creating and resolving persistent, verifiable identifiers without centralized registries or authorities.
They enable secure, portable, and self-sovereign identity for people, organizations, and devices.

Carbon provides a Java implementation of the Decentralized Identifiers (DIDs) v1.0 specification, making it easier to build and integrate DID-based solutions in Java applications.

The library defines core primitives such as Did and DidUrl for working with identifiers, together with interfaces for resolving DIDs into DID Documents. These components form the foundation for parsing, constructing, and resolving identifiers in a modular and extensible way, supporting multiple DID methods and resolution strategies.
