US Military Runs Live Bitcoin Node to Monitor Network Activity and Secure Networks

US Admiral Samuel Paparo told Congress that the US military is running a live Bitcoin node. This marks the first public confirmation by a sitting US combatant commander of direct military participation in the Bitcoin peer-to-peer network.

The node, which holds the full history of the blockchain and enforces the network's rules, is not being used to mine Bitcoin. Instead, it is being used to monitor network activity and run operational tests on securing and protecting networks using the Bitcoin protocol.

Paparo stated that the military's interest in Bitcoin lies in its underlying architecture, specifically its cryptography, blockchain structure, and reusable proof of work. He described his interest as a computer science application rather than a financial one.

The US Indo-Pacific Command, which Paparo commands, oversees US military operations across the Indo-Pacific, the primary theater of strategic competition with China. The command's participation in the Bitcoin network is notable because the protocol was designed to resist control by any single government or institutional actor.
