The food supply chain is a vital yet complex system essential for ensuring global sustainability and food security. With the increasing geographical expansion of the supply chain and the involvement of numerous stakeholders, the process has become longer, more intricate, and prone to various challenges such as lack of traceability, fraud, and inefficient distribution. This project proposes a decentralized food supply chain management system leveraging blockchain technology to enable end-to-end traceability, improve transparency, and deliver reliable information to consumers. The system is designed around three core modules: a Traceability System for recording and verifying product histories, a Trading Mechanism to securely manage ownership transfers, and a Reputation System that allows verified consumers to post immutable product reviews. Key features of the platform include the ability to trace food products globally, prevent the circulation of duplicate and unauthentic items, ensure efficient food distribution, and reduce overall supply chain costs. The solution is implemented using tools and technologies such as JavaScript, HTML, CSS, and Solidity, offering a robust, transparent and secure architecture suitable for real-world deployment in the food industry.
