1.1 Introduction
Information technology revolutionised logistics and supply chain and its contribution is substantial. Treiblmaier (2018) traced the information technology support in various stages starting from 1960. In late 60s and 70s progressive computation has been extensively used in logistics planning for randomized storage and to optimize inventory in managing warehouse and subsequently IT has been used to develop simplified route planning for trucks. In 1980 when personal computers emerged it has been used to support planning activities in logistics . Later in 1990, networking of computers and enterprise resource planning packages transformed linkages between companies and automated various process such as facilities to organize virtual meetings , tracking orders and order-deliver processing . As we all know in 2000 internet’s dominance substantially reconfigured supply chains on upstream and downstream members’ coordination activities. Typical activities are internet supported purchasing , computer aided relationship management and emergence of electronic market places . Later in 2010, IT becomes inseparable in logistics and supply chain ranging from product development , customer relationship management , computer aided manufacturing and radio frequency identification for tracking. Now in the digital era supply chain are gearing towards linking of enterprise resource planning across organizations in the tag of blockchains and embedding transparency in transactions of the end-to-end supply chain . From the above, we have seen the contribution of information technology to physical distribution , however, blockchain is completely reshaping the supply chain to encompass all the information and financial transactional activities.
According to Provenance (2015), blockchain enhances supply chain transparency by allowing every partner to access to information concerning the activities within the supply chain, such as providing customers with the ability to evaluate the products before making a decision. More specifically, blockchain is a distributed database that is based on cryptographic proof instead of trust, which allows two consenting parties to conduct a direct transaction between themselves instead of using an intermediary (Swan 2015; Pilkington 2015; Korpela et al. 2017). Thus, blockchain is a decentralized ledger recording all transaction information within a peer-to-peer (P2P) network to verify and authenticate (Arias and Shin 2013; Swan 2015). In blockchain, records and data are secure , traceable and auditable (Kouhizadeh and Sarkis 2018). The first Blockchain was conceptualized by Nakamoto, the founder of a digital currency Bitcoin (Nakamoto 2008). Blockchain alone does not utilize the advantages of the technology. Implementing emerging technologies with blockchain not only solves the visibility and traceability challenges in supply chain, but also facilitates connectivity and increases transparency . Blockchain technology can clearly be used in business to business (B2B) transactions , Internet of Things (IoT ) and machine-to-machine (M2M) integrations (Korpela et al. 2017). The world is getting more connected; therefore, organisations are placing billions of devices , sensors and actuators in their products and infrastructures. Therefore, IoT and blockchain technology integration is emerging, in the near future, blockchain systems will work solely with data automatically generated from physical IoT devices in the whole supply chain (Banker 2018; Rejeb et al. 2019). Moreover, combining blockchain’s distributed ledger framework with these applications and other emerging technologies such as smart mobile devices , artificial intelligence (AI) , augmented reality/virtual reality , edge cloud computing , RFID and 5G are especially important in autonomous decision making. Notably, blockchain, IoT, AI and 5G complement each other and could provide shared benefits in form of more reliable data , more secure transactions and auditable capabilities (Gartner 2019; Pavithran et al. 2020). This distributed ledger technology can have profound implications for supply chain sustainability (Kouhizadeh and Sarkis 2018). The fundamental of blockchain are explained in Chapter 2.
Overall, blockchain implications in supply chain is referred as an under-researched topic (Treiblmaier (2018). There is a possibility of applying blockchain technology in the logistics industry by allowing all participants to access information about what went into producing and ordering regarding a known product (Robinson 2016). At the same time, allowing every touchpoint in the supply chain to be tracked , recorded , which increases the supply chain information transparency (Brown 2016; Korpela et al. 2017).
1.2 Motivation
Recent studies are replete with finding and identifying improvements to the current challenges and limitations of blockchain (Swan 2015) as well as the security and privacy issues in blockchain (Aitzhan and Svetinovic 2016), but efforts related to the application of blockchain in different industries and its benefits and challenges are markedly insufficient and meagre. To overcome this a systematic literature review of block chain application has been carried out by...
