Blockchain-Based Healthcare System for Secure Patient Records

In this project, a blockchain-based healthcare system was developed to securely store and retrieve patient records. The system ensures privacy, security, and accessibility by encrypting patient details before storing them on the blockchain. Only authorized personnel can retrieve the data, making it a tamper-proof solution for medical data management.

Technologies Used:

• Truffle: For blockchain development.
• FastAPI: For backend services.
• Ganache: For generating tokens.
• MetaMask: For handling transactions.

Key Features:

• Decentralized and tamper-proof system.
• Simulates data access across multiple devices.
• Ensures privacy and security of medical data.

Practice-Verified Codes and Commands:

Setting Up Truffle:

npm install -g truffle
truffle init
truffle compile
truffle migrate

FastAPI Backend Setup:

pip install fastapi uvicorn
uvicorn main:app --reload

Ganache for Local Blockchain:

npm install -g ganache-cli
ganache-cli

MetaMask Integration:

1. Install MetaMask browser extension.

2. Connect to the local Ganache network.

3. Import accounts using private keys from Ganache.

What Undercode Say:

Blockchain technology is revolutionizing the way we handle sensitive data, especially in healthcare. By leveraging tools like Truffle, FastAPI, Ganache, and MetaMask, we can create secure, decentralized systems that ensure data integrity and privacy. Here are some additional commands and practices to enhance your blockchain and backend development skills:

Linux Commands for Development:

<h1>Manage services</h1>

sudo systemctl start service_name
sudo systemctl stop service_name
sudo systemctl restart service_name

Windows Commands for Development:

<h1>Check network configuration</h1>

ipconfig /all

<h1>Display system information</h1>

systeminfo

<h1>Manage services</h1>

sc start service_name
sc stop service_name
sc query service_name
