Decentralized application for vehicle sharing using tokenization

Vehicle tokenization for efficient sharing/renting

This is a decenralized application for vehicle sharing using tokenization. So vehicle owners need to tokenize the vehicles and once vehicles are tokenized, they are listed and renters can rent them. So when a user rents a vehicle, the ownership of vehicle is transferred to renter from owner. When rental period is over, ownership is transferred back to owner from renter. Before renting a vehicle, renters will have to pay some deposit_money, this money will be serving as security money for vehicle and also if renters are using car beyond the time frame, some part of deposit_money will be deducted and transferred to owner's wallet.

About

In the digital era, traditional vehicle rental systems often face challenges related to transparency, trust, and intermediaries. However, with the emergence of blockchain technology, a new paradigm is reshaping the landscape of vehicle sharing. Blockchain-based tokenization is transforming the way vehicles are rented and shared, enabling a more effective and streamlined process for both owners and renters. By representing vehicles as digital assets on a secure and transparent blockchain network, tokenization empowers participants to engage in peer-to-peer transactions, bypassing intermediaries, and benefiting from enhanced trust and efficiency.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

• HTML
• CSS
• Bootstrap
• NodeJs
• NPM
• Truffle
• Docker
• Ganche
• Sepolia TestNet
• Metamask wallet
• Visual Studio Code

Installing

Follow the below steps to install all the dependencies and run the project

1. Clone the project repository

   git clone https://github.com/shrawank22/vehicle-sharing.git
   

2. Go to root directory of the project folder

   cd vehicle-sharing
   

3. To insall all the dependencies which are there in package.json file, run the following command

   npm install
   

4. Also you need to install truffle using command

   npm install -g truffle@latest
   

5. For compiling and deploying smart contracts, sepolia testnet is used. So go to truffle-config.js file and find line

   provider: () => new HDWalletProvider(MNEMONIC, `wss://eth-sepolia.g.alchemy.com/v2/${PROJECT_ID}`),
   

   Here you need to add your own metamask MNEMONIC and also you need to replace the PROJECT_ID with your own Alchemy project id. The best practice is that you should create a .env file and add both MNEMONIC and PROJECT_ID to that file only and this way you don't have to change truffle-config.js file.

6. When you are done setting up truffle-config file, You have two choices to compile and deploy the smart contracts:

   1. Using Docker (For this, you need to install docker using command sudo apt install docker.io)
      • Docker container is already set up, you need to build the docker image by running command:

        docker build -t truffle-docker .
        

      • Run the docker container

        docker run -it truffle-docker
        

      • That's it, smart contracts are compiled and deployed.
   2. Manually deploying contracts
      • For compiling smart contracts, use command

        truffle compile
        

      • Then for deploying smart contacts on sepolia testnet, run command

        truffle migrate --network sepolia
        

7. For deploying on ganache (For this you need to open Ganache GUI), use command

   truffle migrate --network development
   

   • If you are using ganache CLI, make sure to update PORT in development to 8545

8. Once contract is deployed successfully, You will be getting something like this:

   1_deploy_contracts.js

   Copy the contract address from here, and go to js file and replace the contract address with your address.

9. Now to run the project, use command

   npm start
   

   If everything works well then you will get Server started at port 8080 in terminal after running command npm start. So you need to visit http://localhost:8080/ to view the application.

10. To run test files for smart contracts, use truffle test
