W3C Invites Implementations of VC Data Integrity, Data Integrity EdDSA and ECDSA Cryptosuites, and VC JSON Schema

 The Verifiable Credentials Working Group invites implementations of the following Candidate Recommendation Snapshots:

• Verifiable Credential Data Integrity 1.0 describes mechanisms for ensuring the authenticity and integrity of Verifiable Credentials and similar types of constrained digital documents using cryptography, especially through the use of digital signatures and related mathematical proofs.
• Data Integrity EdDSA Cryptosuites v1.0 describes a Data Integrity cryptographic suite for use when creating or verifying a digital signature using the twisted Edwards Curve Digital Signature Algorithm (EdDSA) and Curve25519 (ed25519).
• Data Integrity ECDSA Cryptosuites v1.0 describes a Data Integrity Cryptosuite for use when generating a digital signature using the Elliptic Curve Digital Signature Algorithm (ECDSA).
• Verifiable Credentials JSON Schema Specification: Among other things, the [VC-DATA-MODEL-2.0] specifies the models used for Verifiable Credentials, Verifiable Presentations, and explains the relationships between three parties: issuers, holders, and verifiers. Verifiability, extensibility, and semantic interoperability are critical pieces of functionality referenced throughout the [VC-DATA-MODEL-2.0]. This specification provides a mechanism to make use of a Credential Schema in Verifiable Credential, leveraging the existing Data Schemas concept.
