Decentralized Ride Sharing

DeRiS

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/deris.sol file contains the logic for all interaction between rider and driver orchestrated on the blockchain run on an Ethereum test network.
• The smart contract can be compiled by running the following node command in the backend folder: solcjs deris.sol --bin --abi
• The above command generates a .bin and a .abi file of the smart contract.
• The .bin and .abi file are used to deploy the smart contract on an ethereum test network.
• The .abi file is also used to create an instance of the contract for the React user application to use to call the functions in the smart contract deployed on the test network.

Ganache test Network

• Ganache (https://www.trufflesuite.com/ganache) is used as the test network to deploy the deris.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.
• Be sure to note down the address 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
• After the application is opened, refer to the documentaion to find out the various ways users can interact with DeRis.
