US Military Runs Bitcoin Node for Cybersecurity Tests, Admiral Confirms

Admiral Samuel Paparo, commander of US Indo-Pacific Command, told the Senate Armed Services Committee that his command is running a Bitcoin (BTC) node and conducting operational tests with the protocol.

The April 21 testimony marked the first time a sitting US combatant commander publicly framed Bitcoin as a national security asset during congressional proceedings.

Bitcoin as a ‘Power Projection’ Tool

Responding to questions from Senator Tommy Tuberville (R-AL), Paparo described Bitcoin as “a peer-to-peer, zero-trust transfer of value” and said that anything supporting all instruments of national power “is to the good.”

He characterized the research as focused on computer science rather than monetary policy.

Proof-of-work, he said, “has got really important computer science applications for cybersecurity,” including protecting data and raising the real-world cost for adversaries conducting cyber operations.

“We have a node on the Bitcoin network right now. We’re doing a number of operational tests to secure and protect networks using the Bitcoin protocol,” he said.

The admiral offered to provide classified details on the tests if requested.

Broader Strategic Context

Paparo’s remarks align with a growing US posture toward Bitcoin at the federal level. Legislators have advanced the BITCOIN Act and a Strategic Bitcoin Reserve through executive order.

Meanwhile, Major Jason Lowery’s “Softwar” thesis previously proposed proof-of-work as a form of cyber power projection.

Tuberville framed the exchange around competition with China, noting that Beijing’s top monetary think tank has published its own strategic Bitcoin research.

INDOPACOM oversees approximately 380,000 personnel across the Asia-Pacific theater, the primary front for US-China strategic competition.

No official follow-up from the Department of Defense has clarified the scope of the tests as of April 22.
