Blockchain-enabled supply chain: analysis, challenges, and future directions

Abstract

Managing the integrity of products and processes in a multi-stakeholder supply chain environment is a significant challenge. Many current solutions suffer from data fragmentation, lack of reliable provenance, and diverse protocol regulations across multiple distributions and processes. Amongst other solutions, Blockchain has emerged as a leading technology, since it provides secure traceability and control, immutability, and trust creation among stakeholders in a low cost IT solution. Although Blockchain is making a significant impact in many areas, there are many impediments to its widespread adoption in supply chains. This article is the first survey of its kind, with detailed analysis of the challenges and future directions in Blockchain-enabled supply chains. We review the existing digitalization of the supply chain including the role of GS1 standards and technologies. Current use cases and startups in the field of Blockchain-enabled supply chains are reviewed and presented in tabulated form. Technical and non-technical challenges in the adoption of Blockchain for supply chain applications are critically analyzed, along with the suitability of various consensus algorithms for applications in the supply chain. The tools and technologies in the Blockchain ecosystem are depicted and analyzed. Some key areas as future research directions are also identified which must be addressed to realize mass adoption of Blockchain-based in supply chain traceability. Finally, we propose MOHBSChain, a novel framework for Blockchain-enabled supply chains.

Evaluation and Classification Risks of Implementing Blockchain in the Drug Supply Chain with a New Hybrid Sorting Method

“…Every time a product goes hand in hand, that is, it is transferred from one person to another, the transaction is completed. The information in this transaction can be fully documented through blockchain technology, creating a permanent history of a product, from its production to its sale [101]. This is recorded in full and can dramatically reduce time delays, additional costs, and human error, which weaken today's trading [102].…”

Special issue on deep learning for emerging big multimedia super-resolution

“…Although Blockchain is making a significant impact in many areas, there are many impediments to its widespread adoption in supply chains. The contribution by Jabbar et al "Blockchain-enabled supply chain: analysis, challenges, and future directions" is the first survey of its kind, with a detailed analysis of the challenges and future directions in Blockchain-enabled supply chains [15]. The authors review the existing digitalization of the supply chain including the role of GS1 standards and technologies.…”

Exploring the Means and Benefits of Including Blockchain Smart Contracts to a Smart Manufacturing Environment: Water Bottling Plant Case Study

“…The factors [2] are as a result of the need from most technology organizations to promote collaboration and heighten the proliferation of automated production processes, from producing a product from raw materials to delivering to a customer in the traditional supply chain [3].…”

“…Currently, some of the technologies used to mitigate this scenario are Radio frequency identification (RFID), Near-field communication (NFC), barcodes, Digital Twin and non-line-of-sight technologies [3]. The use of RFID technology facilitates control and transparency in production process flow, enabling the implementation of data analysis for efficient production process control [8].…”

“…The intricacies of the traditional manufacturing environment are accentuated when moving to a smart manufacturing environment. The challenges that existed previously move on to more complex platforms with the inclusion of Cyber Physical Systems (CPS), Cloud manufacturing, and Machine to Machine (M2M) communication [3].…”
