The Impact of Blockchain on Supply Chains: A systematic Review

Supply chains face many challenges around coordination, information asymmetry, quality assurance, complex disruptions, and traceability. Blockchain is arguably a technology that can address these challenges and make a significant impact. To shed light on the impact of blockchain, we undertake a cross-discipline systematic literature review on blockchain and supply chains. This review focused on identifying blockchain’s current and proposed impacts on the supply chain at three levels: organisational, inter-organisational, and industry. The findings identified twelve core supply chain themes across pre-implementation, post-implementation, and emerging tensions associated with adopting blockchain. These findings extend knowledge by going beyond understanding blockchain and its application and articulating multi-levels of impacts. Based on our review, we propose future research directions. By providing an overview of the current impact of blockchain, the review also offers insights to help managers to make informed decisions around the implementation and use of blockchain in supply chains.
