Towards an IoT and Blockchain-based System for Monitoring and Tracking Agricultural Products

This paper presents the design and implementation of a monitoring and data collection system for agricultural product preservation during transportation to meet authenticity and traceability requirements. The system is built and performed using blockchain and Internet of Things (IoT) technology to use and integrate their benefits. This system comprises a private blockchain network built on the Ethereum platform and powered by the GoQuorum protocol, which enables distributed data exchange among members using a common protocol and cryptographic techniques while ensuring the transparency and integrity of the information. A wireless sensor network has been designed and implemented for collecting data from sensors about the storage environment of agricultural products. This study also proposes using LoRa technology to build low-cost wireless communication networks with broad coverage for data collection from sensor nodes mounted to agricultural products. Furthermore, the integrated online map web assists in real-time monitoring and tracing of information on the process of transporting agricultural products, as well as querying data for completed contracts. Experiments were conducted close to the reality of the application’s desire to deploy the system to calibrate and evaluate the functioning, with promising results.
