US Military Runs Bitcoin Node to Test Cybersecurity and National Security Uses

The U.S. military is currently operating a Bitcoin node as part of ongoing cybersecurity and network defense experiments, according to Admiral Samuel Paparo, commander of U.S. forces in the Pacific. Paparo disclosed the development during a House Armed Services Committee hearing on April 23 while responding to questions from Representative Lance Gooden about Bitcoin’s national security role.

Paparo told lawmakers that the military is in an experimental phase, using the Bitcoin network to monitor activity and conduct operational testing. He clarified that the military is not mining Bitcoin but instead evaluating how the Bitcoin protocol can help secure and protect sensitive systems.

The statement provides rare public insight into how government agencies may be exploring blockchain infrastructure beyond financial use cases.

Focus on Cryptography, Security, and Strategic Competition

Paparo emphasized that the military’s interest lies in Bitcoin’s underlying technologies, including cryptography, blockchain architecture, and reusable proof-of-work mechanisms. He described Bitcoin as a computer science tool with potential to strengthen cybersecurity frameworks and support secure communications.

The discussion also connected digital asset policy to broader strategic priorities, including maintaining U.S. dollar dominance. Paparo referenced support for measures such as the GENIUS Act, suggesting that emerging financial technologies are increasingly linked to national security and geopolitical competition.
