Permissioned Blockchain-Based Double-Layer Framework for Product Traceability System

Abstract

Blockchain-based product traceability systems are receiving increasing attention from both industry and academia. Existing systems make full use of the traceability and non-modification characteristics of blockchain technology and realize the openness and transparency of product traceability information in the entire supply chain. However, existing systems do not consider government regulation, cannot protect enterprise sensitive private data effectively, and have performance bottlenecks. To address these problems, this paper proposes a product traceability scheme based on the permissioned blockchain within a doublelayer framework. We introduce the double-layer framework and describe its advantages in detail. We also describe the smart contracts (chain code) in the double-layer framework. Finally, we test the performance of the proposed scheme through simulation experiments. The simulation results demonstrate the performance of nodes in the main layer, which is very important for consumers to obtain product traceability information, is optimized.

“…Sudhan et al [83] state that "the unique nature of BC ensures the CIA of data stored and accessed in a decentralized manner". DLT has special properties which enable DLT integrated systems to have inbuilt data security and assurance, rendering the CIA of systems [84], [14], [85], [86], [28], [87], [8]. As a result, current research work in the area of DLT in SCSM was The authors clustered these properties of DLT based on their security aspects as illustrated in Fig.…”

“…Ding et al [85] proposed a product traceability scheme based on the permissioned BC within a double-layer framework, designed to improve existing BC-based traceability systems. According to the authors, the weaknesses of existing systems include the lack of government regulatory agent participating in BC-based traceability systems, lack of adequate protection of private enterprise data and performance bottlenecks.…”

A Systematic Literature Review of Industry 4.0 Technologies within Medical Device Manufacturing

“…Table 3 details a summary of the total 317 unique features within the articles included in the SLR, which have been grouped into five subcategories (fault detection, predictive maintenance, communication, virtualization, human machine interference (HMI)). Various Industry 4.0 IT solutions are used in fault detection [45][46][47], predictive maintenance [48][49][50], communication [51][52][53], virtualization [42,54,55], and human-machine interference (HMI) [56][57][58].…”

A Blockchain Based Solution for Medication Anti-Counterfeiting and Traceability

“…The consensus mechanism enables multi-party participation by the nodes on the network of blockchain, allowing them to jointly maintain the same medication's information set. The more parties participating in the medication flow in the supply chain, the larger the data size jointly maintained, thus the more trustworthiness could be brought to the consumers [31]. The blockchain-based endorsement can become the effective trustworthiness mechanism, reducing the likelihood of a counterfeit.…”
