Blockchain applications in supply chain management: a systematic review of reviews

Purpose A fragmented research field exists on the applications of disruptive technologies like blockchain in supply chain management. Thus, the purpose of this study is to present a systematic review of literature reviews, summarising the applications of blockchain in various kinds and facets of the supply chain to date.Design/methodology/approach The literature search was conducted using Scopus and Web Of Science databases, and reporting was performed using PRISMA guidelines. In total, 43 review papers were identified, and 15 reviews applicable to the study were synthesised.Findings Blockchain technology is still in its infancy; however, it is gaining high utility in supply chain management. The technology is constantly expanding its application base, and it has enormous potential to cut out intermediaries and improve the efficiency of supply chains. Taking a look at the past and the present, the current study explores unexplored research avenues for the future.Research limitations/implicationsThis study provides key insights to academia interested in exploring and advancing the topic.Practical implications This study will benefit practitioners and business managers exercising the potential of such a technology in various industrial contexts.Social implications The outcome of this study has the potential to bring many benefits to society at large. These benefits, if fully realised, could positively impact the society.Originality/value To the best of the authors' knowledge, this is the first broad systematic review of reviews analysing the information about blockchain applications and implementation in the supply chain. Based on its constructive overview of the review studies published to date, this study contributes to the supply chain management literature by providing a table of reference for future researchers.
