AgriTrust: A Blockchain-Based Bidding System for Transparent and Secure Agricultural Trade

Abstract — AgriTrust is a bidding platform driven by blockchain technology that aims to improve agricultural trade's efficiency, security, and transparency. Price manipulation, a lack of trust, and ineffective transaction procedures are common problems in traditional marketplaces. AgriTrust uses smart contract-driven bidding to solve these problems, guaranteeing that every bid, crop listing, and transaction is safely documented on an unchangeable blockchain ledger. In order to prevent data manipulation and improve supply chain confidence, the platform incorporates blockchain-based product verification, allowing end-to-end traceability. In order to ensure fair price discovery, purchasers must follow competitive bidding procedures, while farmers can offer commodities with a specified base price and bid deadline. Customers can check the history and legitimacy of any goods by using a QR code-based authentication mechanism that connects it to its blockchain record. By providing a strong and impenetrable trading ecosystem , AgriTrust enhances transaction security, bid transparency, and farmer profitability in contrast to conventional and up-and-coming agri-tech solutions.
