Medical Records System on Aptos Blockchain

A secure decentralized healthcare records management system built on the Aptos blockchain. This application enables healthcare providers to manage patient information, medical records, and appointments with blockchain-powered security and immutability.

Features

• Secure Patient Records: Store and manage patient information securely on the blockchain
• Medical History Management: Track patient diagnoses, treatments, and outcomes
• Appointment Scheduling: Schedule and manage patient appointments
• Blockchain Security: All data is cryptographically secured on the Aptos blockchain
• Wallet Integration: Connect with Petra, Martian, or other Aptos-compatible wallets
• Provider Authorization: Access control ensures only authorized healthcare providers can access patient data

Project Structure

• Frontend: Next.js application with UI components (shadcn/ui)
• Smart Contracts: Move language contracts deployed on Aptos
• AI Agent: Intelligent assistant that can interact with the blockchain system

Getting Started

Prerequisites

• Node.js 16+ and npm/yarn/pnpm
• Aptos wallet (Petra, Martian, or compatible wallet)
• Aptos CLI (for contract deployment)

Installation

1. Clone the repository and install dependencies:

   git clone https://github.com/debayudh07/aptos-project
   cd aptos-healthcare/frontend
   npm install

2. Set up environment variables: Create a .env.local file with:

   NEXT_PUBLIC_NETWORK=testnet
   NEXT_PUBLIC_MODULE_ADDRESS=0x8e46115deae69c3ffc41c50f29c94501935467de0212a666d2f0f0b83f1574ac
   NEXT_PUBLIC_MODULE_NAME=healthcare
   

Running the Application

Start the development server:

npm run dev

Open http://localhost:3000 with your browser to see the application.

Setting up the AI Agent

1. Navigate to the agent directory:

   cd ../aptos-agent

2. Create a .env file with your Groq API key:

   GROQ_API_KEY=your_api_key_here
   

3. Install Python dependencies:

   pip install -r requirements.txt

4. Run the AI agent:

   python main.py

The agent will now be available to interact with the blockchain application.

Open http://localhost:3000 with your browser to see the application.
