Implement verifiable credential applications for proof certification and trust**

[jobbykings]

Create advanced verifiable credential applications for proof certification, trust establishment, and interoperable credential management.

Requirements:
Verifiable credential application implementation
Proof certification system
Trust establishment mechanisms
Interoperable credential management
VC security verification
Credential efficiency optimization

Acceptance Criteria:
GIVEN VC application, WHEN used, THEN proof certification is standardized
GIVEN trust establishment, WHEN active, THEN credential authority is verified
GIVEN interoperability, WHEN achieved, THEN credentials work across systems
GIVEN security verification, WHEN performed, THEN VC properties are cryptographically sound
GIVEN efficiency optimization, WHEN applied, THEN VC operations are fast
