Key differences:
- Updated test suite version from September 21, 2025 to September 28, 2025
- Digital Bazaar company name updated from 'Digital Bazaar' to 'Digital Bazaar, Inc.'
- Multiple test failures persist across issuers and verifiers including proof validation errors
- Critical security vulnerabilities where systems incorrectly accept invalid credentials
- Widespread test failures with 50% of issuers failing mandatory data integrity tests
- Error handling issues with incorrect HTTP status codes (503 instead of 400/422)
- Network connectivity problems affecting interoperability tests
- Proof value validation failures across multiple implementations
news:
The Ed25519Signature2020 standard is a cryptographic suite used for creating and verifying digital signatures on Verifiable Credentials, providing secure digital document authentication. The test suite assesses interoperability between different implementations to ensure consistent behavior across systems. The latest update reveals ongoing critical security issues where implementations fail to properly validate digital proofs, accept forged credentials, and exhibit widespread non-compliance with the standard's requirements.
