Blockchain Model

Overview

This is a simple blockchain model implemented using JavaScript, Node.js, Express.js, Postman, and Redis. This project serves as a basic demonstration of how a blockchain works and how it can be interacted with via a RESTful API.

Prerequisites

Before you begin, ensure you have met the following requirements:

• Node.js and npm installed on your machine.
• Redis server installed and running locally or on a remote server.
• Postman for testing the API.

Getting Started

To get started with this project, follow these steps:

1. Clone the repository to your local machine:

   git clone https://github.com/Shivam9060/Blockchain_Model-JS-.git

2. Navigate to the project directory:

   cd Blockchain_Model-JS-

3. Install the required dependencies:

   npm install

4. Configure Redis:

   Ensure that your Redis server is running and accessible. You may need to modify the Redis connection settings in config.js if your setup is different.

5. Start the application:

   npm start

6. The blockchain model should now be running locally at http://localhost:3000.

Project Structure

The project directory is structured as follows:

• Block.js: The main application file.
• blockchain.js: Contains the blockchain logic.
• index.js: Contains the API routes.
• blockhain.js: Contains the Blockchain.
• config.js: Configuration settings for Redis and other variables.

API Endpoints

• GET /blocks: Get a list of all blocks in the blockchain.
• POST /mine: Mine a new block and add it to the blockchain.
• POST /transactions/new: Create a new transaction.
• GET /chain: Get the full blockchain.
• GET /nodes/resolve: Resolve conflicts in the network.

For detailed usage and request/response examples, refer to the API documentation or Postman collection.

Using Postman

To interact with the blockchain API, you can import the included Postman collection (blockchain-model.postman_collection.json) for easy testing and exploration. Make sure the server is running before making requests.
