Block Chain Ehr System
BlockCare EHR ā Decentralized Electronic Health Record System
BlockCare EHR is a secure, decentralized web application for managing electronic health records using blockchain technology. It ensures that medical data is tamper-proof, access-controlled, and transparently shared only with verified healthcare providers. The application uses React.js and Tailwind CSS on the frontend, and integrates Ethereum smart contracts for identity verification and access control.
Features
- Blockchain-Based Doctor Verification
- Doctors are validated on-chain to ensure trust and authenticity.
- Decentralized Health Record Access
- Patients have full control over who accesses their records.
- Tamper-Proof Medical Records
- Every record update is stored immutably via smart contracts.
- Responsive UI
- Modern, clean interface built with React.js and Tailwind CSS.
- Off-chain Data Storage (Optional)
- Medical files can be stored on IPFS with hash mapping on-chain.
