The 2025 U.S. National Defense Authorization Act has institutionalized the use of blockchain technology in military applications. The act mandates the assessment of blockchain for defense strategies, launching the 'Defense Blockchain Internal Testing Program.' This initiative aims to utilize blockchain's decentralized features for rapid fund mobilization, sanction evasion, and secure data exchange. The U.S. Department of Defense, led by Secretary of Defense Lloyd Austin, is spearheading this strategic shift, with experts and agencies like the Constellation Network exploring blockchain's potential in resource tokenization and battlefield operations.
