Abstract
In Internet of things, compared with the traditional traceability system, the existing system has difficulties in operation, data are easily lost, data are uncoordinated, standards are not unified, and so on. In this paper, based on the characteristics of blockchain, the traceability model of urban fruits is established to reduce the risk of counterfeit and shoddy urban fruits. The collected data is integrated into the chain for diversified display, providing different permissions and platforms for multiple roles. Blockchain and supporting intelligent hardware are used to realize the real record and tracking of the whole process of fruit. Improve the transparency and efficiency of supply chain, and reduce the supply chain cost. The experimental results show that the proposed algorithm model can be applied to the fruit service field and effectively improve the service level of smart city.
Highlights
The quality and safety of urban fruit in the Internet of things (IoT) have always been a hot topic of research
Manufacturers, processors, and sellers of urban fruit quality traceability models based on blockchain need to enter and query data, and the government or organization can view the data entry
In the Internet of things, according to the characteristics of the blockchain, the traceability model of urban fruits is created, and the architecture design based on the traceability model of blockchain is proposed
Summary
The quality and safety of urban fruit in the Internet of things (IoT) have always been a hot topic of research. Under the coverage of the whole process of the traceability system, once a problem occurs, the traceability system can quickly respond, obtain the information of the whole process of the production and circulation of the problem product, conduct troubleshooting and positioning [3], determine the root cause of the problem, and solve the problem . Previous incidents such as “tainted milk powder” and “gutter oil” have generally raised people’s awareness of quality and safety.
