Blockchain-Based Medical Insurance System
This project is a comprehensive solution to address trust issues in the medical record-sharing process among patients, doctors, insurers, and pharmacies. The system leverages blockchain technology to digitize prescriptions and ensure secure, tamper-proof data sharing.
Key Features Include:
- Microservices Architecture: Built using Docker containers for scalability and modularity, managed with Docker Compose.
- Backend API: Designed with ExpressJS to handle business logic and data processing.
- Frontend: Developed with AngularJS for an intuitive user interface.
- Monitoring: Integrated Prometheus to track the health of blockchain components, with Grafana for advanced visualization and performance insights.
- Alerting: Configured automated alerts to respond to anomalies, ensuring minimal downtime.
- Automation: Bash scripts automate deployment and setup, streamlining processes and reducing human error.
- Security: Cryptographic techniques and consensus mechanisms ensure data integrity and privacy across a peer-to-peer blockchain network.
The project demonstrates expertise in DevOps practices, system monitoring, and blockchain application development. It also ensures trustless collaboration among parties, significantly improving efficiency and transparency in insurance processes.
