SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides guidance on implementing verifiable presentations according to the W3C Verifiable Data Model (VCDM) specification, enabling secure and standardized sharing of digital credentials.

Core Features & Use Cases

  • Presentation Structure: Understand the core components and properties of a Verifiable Presentation.
  • Credential Aggregation: Learn how to include multiple Verifiable Credentials within a single presentation.
  • Enveloped Data: Handle Verifiable Credentials and Presentations secured using enveloping mechanisms.
  • Derived & Self-Asserted Claims: Implement advanced scenarios involving derived data and self-asserted claims.
  • Use Case: A user needs to present their driver's license and a university degree to an online service. This Skill guides the wallet on how to construct a Verifiable Presentation containing both credentials.

Quick Start

Use the w3c-vcdm-presentations skill to understand how to structure a verifiable presentation that includes multiple verifiable credentials.

FAQPage Schema
How do I structure a W3C Verifiable Presentation to share multiple digital credentials?

A W3C Verifiable Presentation aggregates multiple Verifiable Credentials into a single standardized structure. It defines core properties and semantics to facilitate secure and interoperable digital credential exchange with an online service.

What are enveloped credentials in a W3C Verifiable Data Model?

Enveloped credentials in a W3C Verifiable Data Model are Verifiable Credentials and Presentations secured using enveloping mechanisms. This approach packages the credential data within a secure wrapper for protected digital identity exchange.

How do I include derived claims and self-asserted data in verifiable presentations?

Including derived claims and self-asserted data in verifiable presentations involves implementing advanced scenarios within the W3C specification. This allows users to present computed data and personal claims alongside authoritative credentials.

Can I use this approach to present a driver's license and university degree together?

Yes, you can use a verifiable presentation to present a driver's license and university degree together. The W3C specification defines how a wallet constructs a single presentation containing multiple credentials for a verifier.

Do I need any specific blockchain dependencies to implement W3C verifiable presentations?

No specific blockchain dependencies are required to implement W3C verifiable presentations. The specification focuses on presentation structure, semantics, and processing for decentralized identity rather than mandating specific platform dependencies.
