Design Framework for Food Supply Chain Industry with IoT using Blockchain

Integrating blockchain technology with the Internet of Things (IoT) in the food supply chain offers a transformative approach to enhancing transparency, traceability, and operational efficiency. This paper presents a comprehensive implementation framework that unifies these advanced technologies into a seamless system, addressing critical challenges in food safety and quality management. The framework comprises five essential processes: IoT device deployment, secure data transmission, blockchain-based data storage, user-friendly frontend development, and system deployment. Firstly, IoT devices, including sensors and RFID tags, are to be strategically deployed across the supply chain to gather real-time data on vital parameters such as temperature, humidity, and location. The data should be transmitted securely using advanced wireless communication protocols to ensure data integrity and prevent tampering. Subsequently, this data is stored on a blockchain platform, leveraging its immutable and transparent nature to create a secure and tamper-proof record of all transactions. A user-centric frontend interface is developed to provide stakeholders with real-time access to blockchain data, facilitating effective tracking of food products from farm to table. The final deployment phase ensures the integration of IoT devices, secure data transmission, blockchain storage, and the frontend interface into a cohesive and operational framework. This integrated framework not only enhances the accuracy and reliability of data collection but also ensures the integrity and traceability of the food supply chain. This paper aims to offer a detailed blueprint for researchers and practitioners interested in implementing blockchain and IoT technologies in the food supply chain, highlighting the potential benefits and associated challenges of this innovative approach.
