Blockchain-Based Safety Management System for the Grain Supply Chain

Abstract

In recent years, various food-safety issues have aroused public concern regarding safety in the food supply chain. Since grains are closely linked to human life and health, it is necessary to effectively manage information in the grain supply chain. The grain supply chain is characterized by a long life cycle, complex links, various hazards, and heterogeneous information sources. Problems with traditional traceability systems include easy data tampering, difficult hazardous-material information management, the ''information isolated island'' problem, and low traceability efficiency in the whole supply chain. Blockchain is a distributed computing paradigm characterized by decentralization, network-wide recording, security, and reliability. As such, it can reduce administrative costs and improve the efficiency of information management. Based on literature research and a field investigation of wheat-processing enterprises in Shandong Province, We analyze the operation process of grain supply chain. This study, therefore, proposed a new system architecture in the entire grain supply chain based on blockchain technology and designed a multimode storage mechanism that combines chain storage. This prototype system was tested and verified using actual cases and application scenarios. Compared to traditional systems, the proposed system is characterized by data security and reliability, information interconnection and intercommunication, real-time sharing of hazardous-material information, and dynamic and credible whole-process tracing. As such, this system is highly significant and has reference value for guaranteeing food quality and safety-process traceability.

SESCF: A Secure and Efficient Supply Chain Framework via Blockchain-Based Smart Contracts

“…Furthermore, blockchain has been introduced in supply chain areas to make the chain more transparent, authentic, and trustworthy. A lot of research has been done to ensure the security and integrity of the supply chain [23,24]. A shared, consensus-based, and immutable ledger helps track the origin and transformations undergone in the supply chain.…”

“…In Table 1, we give a comparison between SESCF and the existing blockchain-based supply chain systems in terms of functionalities [14,23,25,29]. Although current work uses blockchain to solve problems in the supply chain, most research work has focused on only one aspect of the supply chain.…”

“…erefore, we first proposed an efficient supply chain framework based on blockchain, which guarantees the fairness and security of the information flow, logistics, and capital flow of the supply chain at the same time. In addition, we compare the efficiency of SESCF and Scheme [23]. In comparison, we only consider primary operations with significant overhead and ignore operations with low complexity.…”

“…In comparison, we only consider primary operations with significant overhead and ignore operations with low complexity. We implement Scheme [23] based on SescfDapp. Figure 12 indicates the evaluation of the quality inspection and traceability function in the experiment.…”

“…Both two schemes must check whether the parameters of the goods meet the requirements of production indexes. Scheme [23] needs to verify the current node information first and then upload and package the goods information. Meanwhile, SESCF does not need to perform these operations.…”
