Supply Chain Transparency Using Blockchain: Benefits, Challenges, and Examples

This chapter studies the emergence of blockchain technology as an effective tool for providing transparency in supply chains. We first discuss how supply chain applications of this technology differ from cryptocurrency networks, and identify why this technology is useful in supply chains. We then classify its applications into three types: improvement of process efficiency, supply chain optimization, and creation of new and innovative use cases. These three types of applications are differentiated by their ease of implementation and scope of benefits. For each type of application, we select recent successful examples and use both interviews with the companies and secondary publications to examine the value generation potential.
