The United States military is running a live Bitcoin node and conducting operational tests on the protocol for network security purposes, according to testimony delivered Tuesday by Admiral Samuel Paparo, Commander of US Indo-Pacific Command.
Paparo’s confirmation came during a fiscal year 2027 defense authorization hearing before the Senate Armed Services Committee. Under questioning from Senator Tommy Tuberville on whether US Bitcoin leadership strengthens deterrence against China in the Indo-Pacific, the four-star admiral didn’t hedge.
“We have a node on the Bitcoin network right now,” Paparo said. “We’re doing a number of operational tests to secure and protect networks using the Bitcoin protocol.”
First Public Characterization as National Security Asset
This marks the first time a combatant commander has publicly characterized Bitcoin as a national security asset in congressional testimony. Paparo called Bitcoin “a peer-to-peer, zero-trust transfer of value” and “a valuable computer science tool as a power projection.” He added that Bitcoin’s proof-of-work protocols “impose more cost” on attackers and have “really important computer science applications for cybersecurity.”
The node isn’t being used for mining or treasury accumulation. It’s research infrastructure. Paparo told the committee he’d prefer to go deeper on specifics in a classified setting.
Reframing the Conversation
The validation of proof-of-work as zero-trust cybersecurity infrastructure by one of the most powerful militaries in the world shifts the debate. For years, Bitcoin has been dismissed by institutional critics as wasteful or speculative. Paparo’s testimony treats the protocol as something else entirely: digital weapons-grade security architecture.
A 2024 Naval Postgraduate School study previously examined Bitcoin’s military significance in special operations, noting that “steganography is the practice of hiding messages in plain sight” and that “Bitcoin enables intelligence to exist one step below the radar of a sophisticated enemy.” That framing appears to have moved from academic speculation to active operational testing.
Countries still debating Bitcoin through the lens of financial regulation are now watching the US Department of Defense validate it as a tool of national power. The question isn’t whether Bitcoin has institutional legitimacy anymore. It’s whether other nation-states are prepared to compete on the security layer.
