Blockchain based medical records

Medygon 👾

This project was a part of Ingenious Hackathon 3.0

Overview

• Blockchain-based medical records on Polygon's Matic network
• Medygon solves the problem of tampering with medical records through blockchain's immutability.
• Currently, Doctors and Patients are the stakeholders considered in the transaction.
• Initially, the Patient grants access to the Doctor.
• Only after that, the Doctor can view the patient in his/her list and add documents for that Patient.
• The uploaded report can be viewed by the Patient - and each upload is identified by the Doctor's public key.
