Decentralized E-Commerce using ETHEReact!

Description

ETHEReact is a full-stack DApp, showcasing e-commerce capabilities without relying on any traditional database for the backend. Instead, it utilizes the Ethereum Virtual Machine (EVM) as its backbone. While not a product in itself, it serves as an idea for aspiring blockchain enthusiasts to explore the full potential of decentralized applications, from end to end.

• This app utilizes Truffle-powered testrpc (also known as ganache) for local development.
• Web3 serves as the bridge between Ethereum and ReactJS

Setup

• Install the latest version of NodeJS
• Install truffle globally using npm install -g truffle
• Install Ethereum RPC globally using npm install -g ethereumjs-testrpc
• Clone this Repo using git clone https://github.com/PruthviKumarBK/Decentralized_eCom.git
• cd Decentralized_eCom
• Below is the command sequence to be executed in the terminal or command prompt:

  cd backend
  testrpc -l 9000000000 -p 8484
  

  This will navigate to the 'backend' directory and instantiate a testrpc server with the specified gas limit and port. Make sure to leave the server running for Ethereum to be operational on your local development machine.

• Change directory to 'backend' and compile the Solidity contracts, then migrate them to your Ethereum server. Depending on your setup, you might use Truffle commands like truffle compile and truffle migrate to achieve this."

  • truffle compile (On Windows 10, truffle.cmd compile)
  • truffle migrate (On Windows 10, truffle.cmd migrate)
  • truffle console (On Windows 10, truffle.cmd console)
    • In console, retrieve SHA256 addresses for Supplier.sol and Customer.sol contracts.
    • We can get that using Supplier.address
      • Copy this SHA256 string. We will need this later. [TAG - Supplier SHA256]
    • Get Customer contract address using Customer.address
      • Copy this SHA256, We will need this later. [TAG - Customer SHA256]

• Now, let's get the front end functional.

• Open the file named 'EthereumSetup.js' (Decentralized_eCom/frontend/src/EthereumSetup.js)

  • Copy SupplierAddress from [TAG - Supplier SHA256] step to line number 13. (let supplierAddress = '<YOUR SHA256 Address for Supplier Contract>')
  • Copy CustomerAddress from [TAG - Customer SHA256] step to line number 14. (`let customerAddress = '').
  • Save file EthereumSetup.js

• Open a new terminal/cmd, navigate to the current working directory, and then change directory to 'frontend' using the command: cd frontend.

• npm install

• npm start

Welcome to decentralized e-commerce! While the UI may appear basic, it showcases the entire process: Supplier adding a product to the marketplace -> Customer making a purchase -> Supplier shipping the order -> Customer acknowledging delivery. And all of this happens on the blockchain! Exciting stuff!
