A verifiable credential is a tamper-evident digital claim that enables secure verification of identities and attributes without physical documents. The W3C data model defines its core components to ensure cryptographic trust between issuers and verifiers.

Decentralized identity uses verifiable credentials to let entities control their own digital identities without a central authority. The ecosystem defines roles for holders, issuers, and verifiers interacting through a verifiable data registry.

The W3C verifiable credentials ecosystem includes holders, issuers, subjects, verifiers, and verifiable data registries. Issuers create credentials, holders store them, and verifiers validate them against a registry to establish digital identity trust.

To conform to the W3C verifiable credentials standard, your documents and implementations must meet specific conformance requirements outlined in the data model. This ensures interoperability and correct processing of decentralized identity credentials.

You need verifiable credentials when building decentralized identity systems that require cryptographic proof of attributes without centralized registries. They provide tamper-evident verification and user-controlled digital credentialing compared to standard certificates.

Yes, this provides an introduction to the W3C verifiable credentials data model 2.0 architecture. It covers the document overview, definitions, ecosystem roles, and conformance requirements to help developers grasp decentralized identity principles.
