MedVault: Blockchain EHR Project

Project Description

Welcome to MedVault, a paradigm shift in managing Electronic Health Records (EHRs). This pioneering project leverages blockchain technology to deliver an enhanced level of security, transparency, and interoperability for EHRs.

MedVault utilizes Ganache from the Truffle Suite, Metamask, Django, and Angular. Ganache, our Ethereum blockchain emulator, provides the ideal environment to develop and test our smart contracts, enabling a secure exchange and storage of health records. Metamask is integrated into MedVault to allow users to interact with our decentralized application (dApp) seamlessly, offering secure transactions within the Ethereum network.

The backend operations are run by Django, a powerful, secure Python-based web framework. Django facilitates user management and provides interfaces for standard CRUD operations on the EHRs.

Angular, a robust JavaScript framework, powers our frontend, providing an intuitive user interface. With its modular architecture, Angular offers smooth integration with Django and Metamask, creating a responsive and engaging user experience.
