PLAUSIBLE & Verifiable Credentials

PLAUSIBLE protocol & W3C VCs

Verifiable Credentials:

The World Wide Web Consortium (W3C) Verifiable Credentials (VCs) V2 framework is an advanced standard designed to enable the issuance, holding, and verification of digital credentials in a secure, privacy-preserving, and interoperable manner across the web. The VC Data Model 2.0 serves as the core specification, detailing the structure and handling of VCs, allowing entities to assert trusted information about a subject. The VC API complements this by defining how applications can interface with VC systems to issue, verify, and store credentials. For managing credentials related to a specific subject, the VC Controller Document provides guidance.

Ensuring the integrity and security of VC data is crucial, addressed by the VC Data Integrity V1.0 specification, which outlines mechanisms for proving the authenticity and integrity of VCs. The VP Request Specification defines how verifiable presentations can be requested, facilitating secure sharing of VCs between parties.

Securing VCs is further enhanced through integration with COSE/JOSE standards, as detailed in resources like Securing JSON-LD Verifiable Credentials with JOSE, VC-JOSE-COSE, and the Linked Data Cryptographic Suite Registry, which provide methods for encrypting and digitally signing credentials to ensure their authenticity and confidentiality. Collectively, these standards and specifications form a comprehensive ecosystem for managing digital credentials, enabling a wide range of use cases from identity verification to access control, thereby enhancing trust and efficiency in digital interactions.

ARC113 has been proposed by GoPlausible to adopt W3C VC standards for the Algorand ecosystem.
