Food Safety Supervision System Based on Hierarchical Multi-Domain Blockchain Network

Abstract

The traditional food supervision system has problems such as lack of industry chain and data fragmentation, which has caused the phenomenon of field regulation to be uncomprehensive in the existing regulatory system and the disposal of response lag. Combining the characteristics of blockchain such as distribution, transparent, and collegiality with the actual needs of regional autonomy, we propose the hierarchical multi-domain blockchain (HMDBC) network structure and the secondary-check mechanism, which can support timely correction and replacement of the malicious supervision nodes by regional nodes co-governance, auxiliary verification of supervision nodes, and arbitration of superior regions. In order to optimize the supervision nodes election, we proposed fuzzy comprehensive evaluation model of credibility, which can be used to objectively and fairly evaluate the comprehensive reputation of each node in that region by considering various influencing factors of node performance indicators. Furthermore, we designed the data block structure model, which can support the supervisor node replacement. Our system can perform automatic food quality detection and warning of substandard food in the entire industrial chain, with the use of smart contracts combined with the food industry standards. Finally, comparing the complexity of the traditional blockchain system with PBFT consortium, our system is more secure, with lower broadcast complexity.

Cross-Department Secures Data Sharing in Food Industry via Blockchain-Cloud Fusion Scheme

“…e ICT electronic agriculture system via blockchain infrastructure guaranteed the integrity of agricultural environment data, conducive to improving sustainable agrarian development [32]. In [33], it is proposed that blockchain applied in the food supply-chain not only could reduce food losses by optimizing product logistics, but it also benefits to improve regulatory efficiency. Saberi et al explored how blockchain could help supply-chain sustainability and guide industry transformation.…”

PABC: A Patent Application System Based on Blockchain

“…In Industrial Internet of Things, He, et al implement a status monitoring system based on blockchain to prevent unauthorized software updating [8]. In the domain of food safety, Tao designed a hierarchical blockchain network and implemented a food safety supervision system [9].…”

Focus on Blockchain: A Comprehensive Survey on Academic and Application

“…In terms of the supervision system problems from the traditional food industry, such as industrial chain deficiency, data dispersion, and so on, it is a risk and an area of concern for systems where there is a need for a high-reliability solution. The Hierarchical Multi-Domain Block Chain (HMDBC) network structure and the secondary inspection mechanism proposed by Tao et al [61] is quite appropriate. Moreover, Blockchain technology can solve some of the most pressing issues in the supply chain, as it provides new methods to record, transmit, and share data.…”
