    GreenBid is a web-based agricultural marketplace that connects farmers and buyers through transparent, real-time online auctions. It eliminates middlemen, reduces paperwork, and promotes fair, market-driven pricing. Farmers can list products with images and set reserve prices, while buyers join live auctions from anywhere with instant updates and results. The platform provides role-based access for Admin, Farmer, and Buyer, ensuring security and efficiency. Built with Node.js/Express and a React frontend using MVC + RESTful API architecture, GreenBid employs JWT authentication, bcrypt hashing, and WebSockets for live bid updates. Data is managed in MongoDB, and interactive dashboards display bid history and price trends—enhancing transparency, user experience, and informed decision-making for all participants.
