Shop

Shop is a decentralized e-commerce application that leverages blockchain technology and artificial intelligence to provide personalized shopping experiences. By utilizing smart contracts on the Polygon network, Shop ensures secure and transparent transactions while giving users control over their data.

Features AI-Powered Recommendations: Personalized product suggestions based on user profiles and preferences. Decentralized User Profiles: Users own and control their data stored securely on the blockchain. Secure Transactions: Smart contracts ensure trustless and transparent purchases. Low Fees & High Scalability: Built on Polygon for fast transactions and minimal fees. User-Friendly Interface: Intuitive design for seamless navigation and interaction.

We built "Shop" as a decentralized shopping platform with AI-driven recommendations, focusing on security, scalability, and user privacy.

Frontend: Utilized React.js for a responsive UI, with Material-UI (MUI) for sleek design components, ensuring a seamless user experience.

Blockchain Integration: Developed smart contracts in Solidity and deployed them on the Polygon PoS network. We leveraged Hardhat for contract deployment and Ethers.js for interacting with the blockchain, benefiting from Polygon's low fees and high throughput.

AI Recommendations: Implemented client-side AI using TensorFlow.js. By processing data in the browser, we provide personalized recommendations without compromising user privacy or relying on centralized servers.

Data Storage: Employed IPFS for decentralized storage of product images and metadata, aligning with the decentralized ethos and enhancing data integrity.

Wallet Connectivity: Integrated MetaMask for user authentication and transaction signing, simplifying the onboarding process.

Partner Technologies: Polygon was instrumental in achieving scalability and cost-efficiency, essential for handling transactions smoothly in a decentralized app.

Notable Hacks: To maintain privacy while offering personalized AI features, we devised a content-based filtering algorithm that runs entirely on the client side. This approach avoids exposing user data and eliminates the need for centralized data processing.

By combining these technologies, we created an app where blockchain ensures secure transactions and data ownership, while AI enhances the shopping experience—all seamlessly integrated for optimal performance.
