RFC-002: Trust Badge Specification#2
Merged
Merged
Conversation
RFC-002 defines the CapiscIO Trust Badge, the cryptographic identity
credential for AI agents in the CapiscIO ecosystem.
## Key Concepts
- Trust Badges are JWS tokens proving agent identity
- Uses did:web for W3C-standard DID identifiers
- Three trust levels: DV (1), OV (2), EV (3)
- Short-lived tokens (default 5 min TTL)
- Revocation via blocklist API
## Relationship to RFC-001
Implements the SVID (Secure Verifiable Identity Document) concept
from RFC-001 AGCP. Badges enable the cryptographic signature validation
required for delegation chain integrity.
## API Endpoints
- POST /v1/agents/{id}/badge - Issue badge
- GET /v1/badges/{jti}/status - Check status
- POST /v1/badges/{jti}/revoke - Revoke badge
- GET /.well-known/jwks.json - CA public keys
- GET /v1/revocations - Bulk revocation list

Summary
Adds RFC-002: Trust Badge Specification - the formal specification for cryptographic identity credentials in the CapiscIO ecosystem.
RFC-002 Overview
The Trust Badge is a JWS (JSON Web Signature) token that provides portable, verifiable identity for AI agents participating in AGCP-governed workflows.
