Registry Architecture
The QR-V™ registry is the authoritative data layer that stores and resolves verification records.
It separates identifiers from records and ensures that all verification results are derived from canonical, auditable data.

Role of the Registry
The registry functions as the system of record for all QR-V™ identifiers and verification objects.
- Stores canonical records
- Maintains lifecycle state (active, revoked, expired)
- Provides deterministic lookup responses
- Supports auditability and traceability
Verification outcomes are derived from registry data rather than presentation layers or user-controlled endpoints.
The registry is the authoritative source of truth for all verification decisions.
Identifiers reference records. Records exist independently of QR codes and interfaces.

Data Model
Each registry entry represents a structured verification record.
- record_id — unique identifier
- issuer_id — issuing entity reference
- record_type — certificate, product, document, etc.
- status — active, revoked, expired
- metadata — structured record data
- hash — integrity reference
- timestamps — lifecycle tracking fields
Records are stored independently from QR representations and are accessed through verification workflows.

Separation of Concerns
| Layer | Responsibility |
|---|---|
| Identifier | Reference to a record |
| Interface | QR display or user interaction |
| API | Verification processing |
| Registry | Authoritative data storage |
| Result | Verification output |
—
Verification Flow
- QR code is scanned
- Identifier is extracted
- Resolver routes request
- API queries registry
- Registry returns canonical record
- Verification result is generated
Each step is deterministic and independent of user-controlled environments.
—
Lifecycle Management
- Creation — record is registered
- Issuance — record becomes active
- Update — metadata or status changes
- Revocation — record invalidated
- Expiration — record expires based on timestamp
Lifecycle states are enforced at the registry level and reflected in verification responses.
—
Integrity and Validation
- Records may include hash references for integrity validation
- Verification responses reflect current registry state
- Issuer actions update registry entries through controlled workflows
- Audit logs track changes and verification events
—
Scalability and Deployment
- Designed for centralized or distributed registry models
- Supports API-based scaling and high-volume verification
- Compatible with issuer portals, plugins, and custom integrations
- Extensible to enterprise and multi-tenant environments
