In globalized operations, one of the challenges that remains is the lengthy and complex nature of supply chains (SCs), which is standing in need of interactions between multiple entities, requiring the determination and creation of trustful relationships among them. Currently, disruptive technological solutions are becoming promising in terms of improving business processes and adding extra value to products and services. One of such is a blockchain technology (BCT), that is built on a decentralized logic and is believed to disrupt supply chain management with its immutability and tamper-proof features. The purpose of this study is to investigate the ability of a BCT and IoT-based solution in bringing trust to SCs. This study explores the potential visibility enhancement enabled by a combination of BCT and IoT throughout the SC involved in a sensitive product distribution, using vaccine distribution as a demonstrative example.
