3. Develop Smart Contracts

   Write smart contracts to automate key processes within the system. An example for inventory management might include:

   
                           pragma solidity ^0.8.0;
   
                           contract InventoryManagement {
                               address public owner;
                               uint256 public productCount;
   
                               struct Product {
                                   uint256 id;
                                   string name;
                                   uint256 quantity;
                                   uint256 price;
                                   address supplier;
                                   address distributor;
                               }
   
                               mapping(uint256 => Product) public products;
   
                               event ProductAdded(uint256 id, string name, uint256 quantity, uint256 price, address supplier, address distributor);
                               event ProductUpdated(uint256 id, uint256 quantity);
   
                               constructor() {
                                   owner = msg.sender;
                               }
   
                               modifier onlyOwner() {
                                   require(msg.sender == owner, "Not authorized");
                                   _;
                               }
   
                               function addProduct(string memory _name, uint256 _quantity, uint256 _price, address _supplier, address _distributor) public onlyOwner {
                                   productCount++;
                                   products[productCount] = Product(productCount, _name, _quantity, _price, _supplier, _distributor);
                                   emit ProductAdded(productCount, _name, _quantity, _price, _supplier, _distributor);
                               }
   
                               function updateProductQuantity(uint256 _id, uint256 _quantity) public onlyOwner {
                                   Product storage product = products[_id];
                                   product.quantity = _quantity;
                                   emit ProductUpdated(_id, _quantity);
                               }
   
                               function getProduct(uint256 _id) public view returns (Product memory) {
                                   return products[_id];
                               }
                           }
                       

4. Backend Development

   Develop the backend services to interact with the blockchain and manage data. Utilize frameworks and libraries suitable for your chosen blockchain platform:

   
                           const Web3 = require('web3');
                           const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
                           const contractABI = [...] // Replace with your contract ABI
                           const contractAddress = '0xYourContractAddress';
                           const contract = new web3.eth.Contract(contractABI, contractAddress);
   
                           async function addProduct(name, quantity, price, supplier, distributor) {
                               const accounts = await web3.eth.getAccounts();
                               await contract.methods.addProduct(name, quantity, price, supplier, distributor)
                                   .send({ from: accounts[0] });
                           }
   
                           async function updateProductQuantity(id, quantity) {
                               const accounts = await web3.eth.getAccounts();
                               await contract.methods.updateProductQuantity(id, quantity)
                                   .send({ from: accounts[0] });
                           }
   
                           async function getProduct(id) {
                               return await contract.methods.getProduct(id).call();
                           }
                       

5. Frontend Development

   Create a user-friendly interface for managing the retail distribution system. Use modern frontend frameworks such as React, Angular, or Vue.js to develop a responsive UI for interactions with the blockchain-based backend.

6. Integration and Testing

   Integrate various components of the system and conduct thorough testing:

   • Functional Testing: Ensure all modules work correctly and interact with the blockchain as expected.
   • Performance Testing: Assess the system's performance under different load conditions.
   • Security Testing: Test the security of smart contracts and data integrity measures.
   • Deployment: Deploy smart contracts on the blockchain network, set up backend services, and launch the frontend application.
