Electronic Health Record System on Blockchain

---

This project is based on a hyperledger fabric network (v2.0) that is managed by hospitals to securely store a patient's medical record while keeping the patient at the center of the process. This means that a patient's medical record cannot be accessed without their consent. All network participants - doctors, hospitals, pharmacies, and private clinics will be given digital certificates by the official medical board of the country to join the network. Doctors will have the ability to perform all the CRUD operations on their patient records.

This project is also useful in crisis situations like the COVID-19 outbreak by providing correct and auditable certificates to people. It also keeps track of those infected during the crisis or pandemic.
