Medical Records on Ethereum Blockchain

This project is a proof of concept for storing medical records on the Ganache blockchain. The frontend is built in JavaScript and the smart contract is written in Solidity.

Getting Started

Prerequisites

To run this project, you will need to have the following software installed on your system:

  • Node.js
  • Ganache GUI
  • Truffle
  • Solc

Installation

  1. Clone the repository to your local machine.
  2. Start Ganache GUI and create a new workspace.
  3. Open a terminal and navigate to the project directory.
  4. Compile the smart contract by running the following command:
solc contracts/records.sol --bin --abi --optimize -o build/
  1. Deploy the smart contract to Ganache by running the following command:
node deploy.js

Note: Before deploying the contract, make sure to update the private key in utils.js (const privateKey = "";) with the private key of your account in Ganache.

  1. After successful deployment, copy the contract address displayed in the console (contractAddress: '0x...').

  2. Update the contract address in contractArtifacts.js by replacing the empty address field (address: ``) with the copied contract address.

  3. Install the required packages by running the following command:

npm install
  1. Bundle the upload.js and fetch.js file using browserify by running the following command:
browserify upload.js -o uploadbundle.js

browserify fetch.js -o fetchbundle.js
  1. If not already installed, install the http-server package by running the following command:
npm install -g http-server

Usage

  1. Start the http-server by running the following command in the project directory:
http-server
  1. Open a web browser and go to http://localhost:8080/.
  2. Double-click on index.html to launch the website.
  3. Enter medical records and store them on the Ganache blockchain.

Built With

  • JavaScript - Frontend programming language
  • Solidity - Smart contract programming language
