Blockchain and IoT based Food Traceability for Smart Agriculture

TLDR

Food safety is a growing global concern, requiring a trusted traceability system that monitors the entire lifecycle of food production. The study proposes a self‑organized, open, ecological food traceability system built on blockchain and IoT that enables all stakeholders in a smart agriculture ecosystem to collaborate even without mutual trust. The system employs IoT devices to automate recording and verification, reducing human intervention, and uses smart contracts to assist regulators in promptly detecting and addressing issues.

Abstract

1Food safety is becoming more and more serious topic worldwide. To tackle the food safety issues from the technical aspect, people need a trusted food traceability system that can track and monitor the whole lifespan of food production, including the processes of food raw material cultivation/breeding, processing, transporting, warehousing, and selling etc. In this paper, we propose a trusted, self-organized, open and ecological food traceability system based on blockchain and Internet of Things (IoT) technologies, which involves all parties of a smart agriculture ecosystem, even if they may not trust each other. We use IoT devices to replace manual recording and verification as many as possible, which can reduce the human intervention to the system effectively. Furthermore, we plan to use the smart contract technology to help the law-executor to find problems and process them timely.
