Blockchain technology is an emerging technology. Over recent years, blockchain technology has been attracting much attention from both scholars and practitioners in the supply chain management (SCM) domain. The idea of Blockchain technology has been originally developed to create cryptocurrencies (Nakamoto, 2008) who helped develop the first bitcoin software and introduced the concept of cryptocurrency to the world. Blockchain technology is a digital ledger that stores records of a transaction in a decentralized manner, usually with no central authority. It is organized in an append-only, sequential chain of blocks using cryptographic links and is designed to be tamper-resistant and tamper-evident. The technical characteristics of Blockchain technology enhance the security of transactions while allowing to create a system of shared trust and eliminating the problem of single point of failure.
