Open
Open data model
Issuers and credentials are stored as plain JSON resources aligned with Open Badges and VC conventions.
Open Trust Infrastructure
Open credential trust infrastructure.
Issue, host, and verify credentials as open resources with explicit trust checks. Built for schools, workforce teams, and learning platforms that need defensible proof.
- Open Badges v2 and v3
- W3C VC compatible
- Ed25519 signature support
- Domain verification controls
Infrastructure guarantees
Designed for high signal: open formats, durable identifiers, and transparent verification.
Provable
Cryptographic integrity
Sign badge payloads with Ed25519 keys and verify them against issuer keys and hosted metadata.
Defensible
Issuer domain controls
Domain validation and well-known issuer checks reduce impersonation and make trust boundaries explicit.
What this implementation contributes
Not a new badge category, but a tighter operational stack with stronger default safety and automation.
Security
SSRF-hardened public verifier
Public verify endpoints block private/internal targets before server-side fetches.
Trust policy
Anti-impersonation domain controls
Well-known issuer verification, verified issuer registry, and safe test-domain handling.
Ops
Self-hosted + agent-friendly
Deploy-anywhere architecture with API, CLI, MCP integration, and llms.txt discovery surface.
Issue in four API calls
From issuer setup to a verifiable assertion URL in a single pipeline.
1. Validate domain
GET /api/validate-issuer-domain
2. Create issuer
POST /api/issuer
3. Create badge class
POST /api/badge-class
4. Issue assertion
POST /api/credential-subject
For issuers
Run reliable issuance pipelines
Use API, CLI, or MCP tools to issue at scale with consistent validation and hosted JSON artifacts.
For verifiers
Evaluate trust quickly
Provide a URL, JSON payload, or issuer profile to inspect structure, issuer validity, and signature status.
