U.S. Military Confirms Operation of Bitcoin Node Under Admiral Paparo

The United States military is actively participating in the Bitcoin network by operating a full node, according to Admiral Samuel Paparo, commander of U.S. Indo-Pacific Command (INDOPACOM). The confirmation was made during a House Services committee hearing on April 22, 2026, marking the first known instance of a U.S. military combatant command directly engaging with the Bitcoin peer-to-peer network.

“We have a node on the Bitcoin network,” Paparo stated. “We’re doing a number of operational tests to secure and protect networks using the Bitcoin protocol.” His remarks followed testimony before the Senate Armed Services Committee on April 21, 2026, where he framed Bitcoin as a strategic tool for American power.

“Our research into Bitcoin is as a computer science tool. It’s the combination of cryptography, a blockchain, and a proof of work. And Bitcoin shows incredible potential as a computer science tool that, through the proof-of-work protocols, actually imposes more cost than just the algorithmic securing of networks and our ability to operate.”

During the Senate hearing, Senator Tommy Tuberville (R-AL) questioned Paparo on whether U.S. leadership in Bitcoin could provide a strategic advantage against China in the Indo-Pacific region. Paparo responded by emphasizing Bitcoin’s role as a computer science innovation rather than a financial asset.

“Bitcoin is a peer-to-peer, zero-trust transfer of value. Anything that supports all instruments of national power for the United States of America is to the good.”

Paparo’s testimony distinguished Bitcoin from typical government discussions on cryptocurrency by focusing solely on its technical and operational applications. He did not reference Bitcoin as a reserve asset, payment system, or speculative instrument, instead positioning it as a critical component of modern military infrastructure.

What Does Running a Bitcoin Node Entail?

A Bitcoin node is a computer running the Bitcoin software that maintains a complete copy of the blockchain and independently validates every transaction and block against the network’s consensus rules. Unlike mining operations, nodes do not generate new Bitcoin. Instead, they enforce protocol rules and relay data across the peer-to-peer network.

For INDOPACOM, operating a node grants the command direct, trustless access to the Bitcoin network, eliminating reliance on third-party intermediaries. The node connects globally, verifying transactions and blocks while rejecting any that violate Bitcoin’s protocol. This participation positions INDOPACOM as an active participant in the network rather than a passive observer.

The military’s “operational tests to secure and protect networks using the Bitcoin protocol” underscore the growing intersection of cryptographic technology and national defense strategies.
