🔍 Overview

This project leverages Minifabric to simplify the deployment and management of a Hyperledger Fabric network. It includes a smart contract that handles CRUD operations (Create, Read, Update, Delete) for managing car assets in the system.

The main objective of this system is to provide a decentralized, secure, and transparent platform for managing automobile lifecycle events.

---

🌟 Features

• Asset Lifecycle Management: Track the lifecycle of automobiles from manufacturing to ownership and status updates in real-time.
• CRUD Operations: Create, read, update, and delete car records with secure blockchain transactions.
• Security & Privacy: Strict access control using MSP (Membership Service Providers) to ensure only authorized users interact with the blockchain.
• Channel-based Communication: Enable secure communication among various participants (manufacturer, dealer, customer, etc.) via Hyperledger Fabric channels.

---

🛠️ Prerequisites

Ensure you have the following installed before setting up this project:

• Minifabric – For quick deployment of Hyperledger Fabric networks
• Docker and Docker Compose – For running the network containers
• Go – For writing and running smart contracts
• Node.js – For any frontend or additional integration needs
• Hyperledger Fabric CLI Tools – For interacting with the Fabric network

Setup and Installation

Follow these steps to set up the Minifabric network and deploy the automobile use case smart contract.

1. Clone the Repository:

   git clone https://github.com/your-repository/automobile-usecase.git
   cd automobile-usecase

2. Install Minifabric:

   Follow the Minifabric installation guide to install Minifabric on your machine.

3. Start the Fabric Network:

   Use Minifabric to deploy the Hyperledger Fabric network.

   minifab netup -s couchdb -e true -i 2.4.8 -o manufacturer.auto.com

   This command starts the network with CouchDB as the state database and Fabric version 2.4.8.

4. Create the Channel:

   After the network is up, create a channel for communication between network participants.

   minifab create -c autochannel

5. Join Peers to the Channel:

   Join all peers to the channel.

   minifab join -c autochannel

6. Anchor Peer Update:

   Update the anchor peer for the channel.

   minifab anchorupdate

7. Profile Generation:

   Generate the network profile for further interaction with the network.

   minifab profilegen -c autochannel

Network Configuration

This setup utilizes Minifabric to create the following network components:

• Peers:

  • peer1.org0.example.com
  • peer2.org0.example.com
  • peer1.org1.example.com
  • peer2.org1.example.com

• Orderers:

  • orderer1.example.com
  • orderer2.example.com
  • orderer3.example.com

• CA (Certificate Authorities):

  • ca1.org0.example.com
  • ca1.org1.example.com

The autochannel is created for secure communication among participants in the network.

🚀 Usage

🛠️ Interacting with the Smart Contract:

Once the Hyperledger Fabric network is set up, you can invoke the CarContract functions using the Fabric CLI or through scripts. Below are some of the key operations you can perform with the contract:

1. Create a New Car Asset

Invoke the CreateCar function to add a new car asset to the blockchain. You will need to pass in the car's unique details such as carID, make, model, and year.

2. Read Car Asset Details

Use the ReadCar function to retrieve information about a specific car by providing its unique carID. This will return the car's make, model, year, and ownership details.

3. Delete a Car Asset

The DeleteCar function allows you to delete a car asset from the blockchain. You must provide the car’s unique carID to remove it from the system.

🔐 Access Control:

The contract ensures that only authorized users under the manufacturer-auto-com Membership Service Provider (MSP) can perform critical actions, such as creating or deleting car assets. This ensures that the lifecycle of car assets is secure and only approved participants can modify the records.
