Healthchain

Store your medical records in a blockchain and give doctors permissions when they need it 🏥

⚠️ ⚠️ ⚠️

This projects is a proof of concept and by no means ready to use in real world use cases. Deploying the smart contract on the real ethereum network might result in high costs!

About

Patient's view

A patient can log in to the web-app and upload his medical records. A list of all uploaded documents is displayed. The documents can be downloaded or deleted. After a medical record document is uploaded, the patient can give a doctor access to his documents. As soon as the Doctor doesn't need access anymore, the permissions can be revoked.

Doctor's view

A doctor sees all documents that he has access to. Document can be downloaded to view them.

Setup development environment

Install Ganche from the official webpage or the latest release on github.
run npm install truffle -g to install truffle globally
[Windows] If you don't have Visual Studio installed, run npm install --global --production windows-build-tools

Building the smart contract

Start Ganache and create a new workspace (quickstart). Make sure the RPC server is set to 127.0.0.1:7545.
in the root of this repository, run:

truffle compile
truffle migrate

Copy the smart contract to the server:

copy-contracts-to-server.ps1

By default the smart contract is deployed to the client. Truffle can't deploy to multiple directories.

Client

A website for patients and doctors to store, view and manage medical records.

Start the react app:

cd client
npm start

Server

Files are uploaded to the server. The server can access the blockchain to check if a user is allowed to download the requested file.

Start the nodejs server:

cd server
npm start
