#By_Rishabh-singh #Ride-Fair Decentralized ride sharing on the Ethereum blockchain. The project contains the frontend website and backend Ethereum Smart Contract to deploy and run the decentralized ride sharing application.

Smart contract

• The backend/ridefair.sol file contains the logic for all interaction between rider and driver orchestrated on the blockchain run on an Ethereum test network.

Ganache test Network

• Ganache (https://www.trufflesuite.com/ganache) is used as the test network to deploy the ridefair.sol smart contract on.
• Once ganache is installed, a test network is started using quickstart. The default test network start on local host at port number 7545 (http://127.0.0.1:7545)
• The backend/mig.js script can be used to deploy the contract onto the ganache test network.
• Make sure to have the right network address and contract deployer enthereum address (from address) set to deploy the contract correctly on the Ganache test network instance.
• If the mig.js file is giving problems in deployment, the Remix IDE (https://remix.ethereum.org/) can also be used to deploy the contract on the ganache test network instance. Again make sure to have the right network address selected.
• If Both the above method don't work then use truffle package option I have made every thing ready first open the truffle-config.js as project into ganache and just open the backend folder and run truffle migrate command your ridefair.sol file would be compiled and deployed over ganche.(I have used this method because i find it easy to implement and deploy over other methods)
• Be sure to note down the address and paste it to the App.js at which the contract was deployed at.

React application

• A frontend React webpage is used to facilitate user interaction with the blockchain.
• To install required packages run npm install in the frontend folder.
• Be sure to have the contract address of the previously deployed smart contract set correctly in the frontend/src/App.js file so the React application can communicate with the previously deployed contract.
• Also make sure to have the right network address set in frontend/src/js_modules/contractInterface.js so the application is connecting the the ganache test network previously deployed.
• Running the npm run start command in teh frontend folder should start up the React application
