The US Department of Defense is actively exploring the potential of blockchain technology in a range of military applications, with the focus primarily being on enhancing security and operational efficiency. The Department’s exploration stems from the recognition of blockchain’s strategic benefits and its ability to revolutionize key areas such as supply chain management. Notably, The Learning Times, hosted by China’s Central Party School, has highlighted digital currency’s growing role as a strategic tool in geopolitical conflicts, underscoring the US’s own efforts in exploring blockchain applications for military use. This trend indicates the potential for blockchain to become a multifaceted platform for security, potentially impacting national defense and international relations strategies alike.
