Smart Contract-Based Refrigerated Container Traceability System

Abstract

A large number of refrigerated container are moved everyday domestically and internationally.The information of refrigerated container is usually stored centrally. It is prone to being tampered by the responsible party, making it difficult to call to account. Due to its characteristics of decentralization, transparency and immutability, blockchain technology can be used to alleviate this problem. In this paper, we propose a blockchain-based refrigerated container traceability system that can trace the information of refrigerated container. We also design a smart contract to realize the information upload and query of refrigerated containers. The experimental results show that the blockchain traceability system and smart contract proposed can effectively monitor and trace refrigerated containers. It guarantees the integrity and reliability of traceability information.
