This paper examines the impact of blockchain on key supply chain management (SCM) objectives, including cost, quality, speed, dependability, risk reduction, sustainability, and flexibility. Blockchain is seen as a transformative technology, particularly in supply chain activities, due to its ability to enhance transparency and accountability. The paper presents early evidence linking blockchain use in supply chain activities to increased transparency and accountability, and discusses case studies of blockchain projects at various stages of development for diverse purposes. The study highlights the mechanisms by which blockchain helps achieve these objectives, with a special emphasis on the integration of the Internet of Things (IoT) and the validation of identities. Key benefits include reduced costs, improved quality control, enhanced traceability, and increased efficiency. The paper also discusses the potential of blockchain to address holistic and atomistic sources of risk, verify sustainability claims, and improve flexibility in the supply chain. Overall, the research suggests that blockchain has the potential to significantly enhance the effectiveness and efficiency of SCM processes.This paper examines the impact of blockchain on key supply chain management (SCM) objectives, including cost, quality, speed, dependability, risk reduction, sustainability, and flexibility.
