CustomsBased Blockchain Solution for Exportation Protection. As part of the international trade supply chain, Dubai Customs acts as the gatekeeper, protecting the society and the economy. During the exportation process, one of the primary responsibilities of the Customs Authority is to authenticate the documents submitted with the exportation declaration application, to ensure the legality of the trade. Due to the lack of direct communication channel among the exportation supply chain participants, authenticating the exportation application documents is a timeconsuming and challenging task. Typically, there is no direct communication paradigm among the supply chain participants. Therefore, in most cases, the authenticating process relies on human judgment. This increases the chance of nondetection of fraudulent exportation documents. In this regard, the redesign of the exportation supply chain to automate the authentication process has become an essential requirement. This paper addresses this requirement by proposing a blockchainbased system, which establishes a direct, tamperproof information exchange mechanism among the participants. We target the car exportation supply chain; however, with slight modification, the proposed system can be easily applied to any other exportation supply chain too. To validate the performance of the proposed system, we implement a ProofofConcept (POC) using the IBM Hyperledger fabric.

Blockchain in the operations and supply chain management: Benefits, challenges and future research opportunities Abstract   Blockchain technologies have captured the imagination of scholars, managers, and practitioners around the world. It is widely accepted by these actors that blockchain is not a buzzword, but a highly disruptive technology that is already remodeling the organizations and their supply chain business models. Despite the meaningful advance in the last years, blockchain applications regarding the operations and supply chain management (OSCM) are still in their infancy. Little is known about the role of blockchain in terms of operations traceability, as well in areas such as ecommerce, agriculture, public services, etc. Therefore, this Special Issue seeks to extend our understanding of blockchain applications in OSCM and how firms create and capture business value with blockchain. To this effect, this Special Issue will provide a wellarticulated and indepth discussion of the role of blockchain in creating value in the domain of OSCM. Specifically, it is expected that more light is shed on how blockchain integrates with and impacts new business models, transforms relationships, and improves performance and competitive advantage in OSCM. Also, the evolution of blockchain was reviewed in order to provide a strong background to the readers. The literature review was performed taking into account a bibliometric perspective of blockchainrelated publications. The review supports the importance of this Special Issue by highlighting the urgent needs of this topic in this reputable journal. Finally, we provide future research directions and a guide for the papers presented in this Special Issue.
