【Abstract】The worldwide food supply chain network firms have embraced digitalization and have changed customers' everyday lives in serval viewpoints. This work proposes a framework for IoT and Blockchain based smart Food Chain Management System (IBFS) aiming to regulate the food inventory systems in an organization focusing on the safety and nature of the items conveyed to the end consumers. The proposed IBFS framework is an IoT-based blockchain with smart contract architecture for trust, reliability, and transparency. A Message Queue Telemetry Transport (MQTT) (Message Queue Telemetry Transport) broker or server is deployed on the broadcast to record all data collected from the IoT sensors. The data provided by IoT-sensors or devices is pooled and gathered by MQTT based cloud brokers and the shipment's geolocation, movement, and temperature are logged. The work uses two types of smart contracts based on Ethereum-based blockchain technology (BCT) environment as the operational backbone written in the Solidity language. The first smart contract deals with custody and the second smart contract deals with shipment or transportation to track the produce. The food supply chain process evaluates the collected data from the IoT sensors managed with the help of blockchain and MQTT servers. The quality of food is measured by evaluating by temperature and humidity function, transition time, final item and for validation of smart contracts. Performance evaluation of IBFS in terms of Gas cost under various test conditions prove the effectiveness of the work.
