National Healthcare System
One trusted view of each patient’s history — with the patient in control of who sees it.
Health recordsIdentityPrivacy
- ✕Patient records are scattered across hospitals, clinics and labs.
- ✕Tests are repeated because results can’t be shared quickly.
- ✕Privacy rules make data sharing complex, and emergencies can’t wait.
Each patient gets a digital health identity. Medical records stay encrypted off-chain, while the ledger holds access permissions and a complete audit trail. Patients grant and revoke consent; every access is logged.
