The Anti-Counterfeit Product Identification System Using Blockchain is a groundbreaking solution designed to combat global supply chain issues related to counterfeit products. It leverages the unique capabilities of blockchain technology to provide a secure and transparent platform for tracking and verifying the authenticity of products across various industries.

The system uses QR codes, an overt technology that can be scanned by a smartphone app, to verify product information and origin. It employs smart contracts to store and execute product verification logic on the blockchain, ensuring tamper-proof data and trustless transactions. The Ethereum network serves as its decentralized database to store product information and status, accessible by authorized parties. A web interface, powered by React, allows users to interact with the system and view product information and history.

The technologies used in this system include Solidity for smart contract development, Hardhat for Ethereum development environment, React for building the user interface, Node.js for backend development, and ethers.js for interacting with the Ethereum blockchain.

This system is significant in solving global supply chain issues as it provides a reliable method to verify the authenticity of products, thereby reducing the prevalence of counterfeit goods. It enhances transparency and trust among stakeholders in the supply chain, from manufacturers to consumers.

To get started with this project,

1. Clone the repository.
2. In identeefi-postgres-database, import the csv files to your own postgres database.
3. In identeefi-backend-node, run npm i to install the dependencies and change the postgres credentials to your postgres crediantials and run node postgres.js to start the backend execution.
4. In identeefi-frontend-react, run npm i to install the dependencies and run npm start to start localhost.
5. You can inspect identeefi-smartcontract-solidity directory to view the smart contract details that is deployed to the Sepolia Testnet.
6. To perform transactions, setup your Metamask wallet and connect your wallet to the Sepolia Tesnet Network and transact using SepoliaETH which can be obtained for free on Seplolia Faucet (https://sepoliafaucet.com/).
