Abstract
In this paper, a food anti-counterfeiting traceability system based on blockchain and the Internet of Things is proposed in response to the problems of data centre-based storage, easy data tampering and data silos in traditional food anti-counterfeiting traceability technology. The system makes use of the decentralized storage and untamperable characteristics of blockchain technology to store traceability data of food in the process of food production, sale and transportation, so as to ensure the uniqueness of food. At the same time, through the Internet of things technology to ensure the authenticity and reliability of the source data of the blockchain. The experimental results show that the system has higher security, lower transaction delay and lower communication cost.
