The U.S. military is now a participant in the Bitcoin network — and it’s doing so for national-security reasons, a senior commander confirmed this week.
Admiral Samuel Paparo, commander of U.S. Indo‑Pacific Command (INDOPACOM), told the House Armed Services Committee on Wednesday that “we have a node on the Bitcoin network right now.” Paparo — who the day before had told the Senate Armed Services Committee that Bitcoin has “incredible potential” as a tool for American “power projection” — clarified that the military is not mining. “We’re not mining Bitcoin,” he said. “We’re using it to monitor, and we’re doing a number of operational tests to secure and protect networks using the Bitcoin protocol.”
A Bitcoin node is simply a computer that stores the blockchain’s full history, enforces the protocol’s rules, and relays validated transactions to the peer‑to‑peer network. Unlike miners, node operators don’t earn rewards or need specialized hardware; running a full node lets an organization verify the state of the network independently rather than trusting third parties. Publicly reachable full nodes numbered roughly 15,000–20,000 as of early 2026, with the actual total likely higher because many run behind firewalls.
One node among tens of thousands doesn’t change Bitcoin’s decentralization, but the revelation is notable for symbolic and strategic reasons. Bitcoin’s architecture has long been touted as a safeguard against control by powerful states. That the U.S. combatant command responsible for the Indo‑Pacific — the same theater that houses the strategic competition with China — is actively testing the protocol raises new questions about how nation‑states might leverage public blockchains for intelligence, resilience, and “power projection.”
Paparo’s public confirmation is the first from a sitting U.S. combatant commander that the military is directly participating in the Bitcoin peer‑to‑peer network, and it underscores growing interest inside defense circles in how decentralized networks could be applied to national‑security missions.
