Blockchain-Based Supply Chain Traceability in IIoT Environments

The IIoT has impacted the supply chain through the realization of real-time observations, automated data capturing, and intelligent decision making in diffused industrial settings. However, the more interconnected IIoT systems and supply chains become, the more difficult maintaining traceability from end-to-end, data consistency and secure information exchange in supply cascade systems becomes. Centralized systems of data management tend to face the same issues of data loss, single points of failures, a lack of visibility, and impedance of interoperability between diverse IIOT devices. These gaps in the supply chain ecosystem require a unique, decentralized, transparent, and scalable to address the many outstanding issues. The purpose of this survey is to evaluate the various attempts to extend the availability of blockchain and its supplied systems to trace IIoT chains. The survey considers recent architectural frameworks in data and integrations, as well as systems with and without blockchain. The work assesses the frameworks and systems. However, the results of the survey construct concern. These include the inability of systems to retain data in digital systems, lack of confidence of many partners, the inability to account remote to these systems. The observations and frameworks reviewed provide evidence of increased traceability, auditability, and visibility of remote objects. Other challenges include a lack of confidence, loss of trust among supply chain partners, and automated contractual agreements. The results of the review construct systems for auditing supply chain systems.
