FAQPage Schema
What is a Decentralized Identifier and how does the W3C DID Core specification define it?

A Decentralized Identifier (DID) is a verifiable identifier that does not require a centralized registry. The W3C DID Core specification defines the DID syntax, data model, and core properties required to resolve DIDs to DID documents.

How do I resolve a DID URL to a DID document?

DID URL resolution involves processing the DID syntax to retrieve the corresponding DID document. The W3C DID Core data model defines the structure of this document, including verification methods and services required for decentralized identity resolution.

What core properties are included in a W3C DID document data model?

The W3C DID document data model includes core properties such as verification methods and services. These properties define the cryptographic keys and service endpoints necessary to establish decentralized identity verification.

When do I need to implement verification methods in a decentralized identity system?

Verification methods are needed when a DID document requires cryptographic proof for authentication. The W3C DID Core specification defines how these methods are structured within the data model to support verifiable credentials and secure interactions.

Can I use the DID Core data model to integrate verifiable credentials into my application?

Yes, the DID Core data model provides the foundational structure for verifiable credentials. It defines the verification methods and services within DID documents that applications need to verify decentralized identity claims.

What is the difference between a DID and a DID URL in decentralized identity syntax?

A DID is the base identifier in decentralized identity syntax, while a DID URL extends it to reference specific resources. The W3C DID Core specification defines the syntax for both, enabling precise resolution of verification methods and services.
