Key differences:
- Added critical guidance on URL length limitations, warning that protocols encoding extensive data in URLs face practical constraints
- Specifically addresses the 2,000 character URL limit that many software libraries enforce
- Strongly recommends against putting information in URL query parameters that could be retrieved via GET requests to interaction URLs
- Provides clear implementation guidance for handling protocol-specific information that exceeds typical URL length boundaries
- Introduces reference to Section Interaction Protocols Response for proper data handling methods
news:
This standard defines a comprehensive system for managing Verifiable Credentials (VCs) and Verifiable Presentations (VPs) using a microservices architecture. It enables secure issuance, management, and verification of digital credentials through a layered approach that separates core communication protocols from business logic. The system supports selective disclosure for privacy, DID authentication protocols for security, and complex workflow management for credential exchanges. The latest update addresses practical implementation challenges around URL length limitations that developers face when encoding protocol-specific information.
