The W3C Verifiable Credentials Data Model specification defines a structured, cryptographically verifiable format for expressing claims about subjects. Credentials are issued by a trusted issuer, held by a subject, and verified by relying parties using digital signatures and Decentralized Identifiers (DIDs), enabling portable, privacy-preserving identity across metaverse and web platforms without centralised databases.

Overview
- The W3C Verifiable Credentials Data Model defines a standard way to express credentials that are cryptographically verifiable, privacy-respecting, and machine-readable. This enables interoperable digital identity across metaverse platforms.
Technical Details
Core Components
- Credential Subject: Entity the credential is about
- Issuer: Entity that creates and signs the credential
- Claim: Assertion about the subject
- Proof: Cryptographic verification mechanism
Key Standards
- W3C VC Data Model 1.1: Core specification (2022)
- W3C DID Core: Decentralized Identifier specification
- JSON-LD: Linked data serialization format
- JWT-VC: JSON Web Token encoding
Verification Process
- Check cryptographic signature validity
- Verify issuer DID resolution
- Confirm credential not revoked
- Validate credential schema conformance
Applications
