U.S. Indo‑Pacific Command Runs Live Bitcoin Node for Cyber Tests

Admiral Samuel Paparo told the Senate Armed Services Committee that U.S. Indo‑Pacific Command is operating a full Bitcoin node to run cybersecurity tests and monitor activity on the network. The testimony was delivered during a public hearing streamed live to Congress.

Paparo said the command set up a full node to validate blocks and transactions, observe network behavior and exercise protocols under different conditions. He emphasized the effort is for network defense and not for creating coins, noting, “We’re not mining Bitcoin. We’re using it to monitor, and we’re doing a number of operational tests to secure and protect networks using the Bitcoin protocol.”

The work focuses on the protocol’s technical features: cryptography, blockchain structure and the proof‑of‑work mechanism. Military officials described the research as an exploration of whether those features can be applied to harden sensitive systems and raise the cost for adversaries attempting cyberattacks.

A full node connects directly to the Bitcoin network, downloads and verifies the blockchain, and relays transactions and blocks. Nodes do not require the specialized hardware used for mining; mining uses separate, energy‑intensive equipment to compete to add new blocks. Operating a node gives direct access to the public ledger without relying on third‑party services, allowing teams to test security responses and protocol behavior without engaging in currency production.

Paparo’s testimony followed earlier comments in which he had raised concerns that some digital assets could enable illicit activity. At the hearing he said research that supports U.S. instruments of national power is beneficial and that INDOPACOM’s work is focused on technical architecture rather than market price.

Lawmakers asked about strategic implications, including whether U.S. engagement with Bitcoin technology affects competition with other countries in the Indo‑Pacific. Paparo told senators the command’s research is about the network’s architecture, not its market value. Congress is debating several policy proposals that address domestic cryptocurrency infrastructure, including measures to expand U.S. production of mining hardware and a proposal to formalize a Strategic Bitcoin Reserve.

Officials cited a rise in cryptocurrency‑related threats as part of the context for the testing. A government program now allows companies to share cyber threat information with federal agencies. Recent large thefts attributed to state‑linked groups, estimated at roughly $600 million from various crypto exploits in April 2026, were raised during discussion of the urgency for improved defenses.

Markets moved after the testimony, with Bitcoin prices rising above $77,000 on April 22 and reports of large institutional purchases around the same period. Data cited by officials show significant concentrations of holdings and mining capacity internationally, including a large balance of coins seized in a 2019 fraud case and substantial U.S. mining capacity and reserves.

INDOPACOM framed the node testing as part of broader defensive cyber efforts in the Indo‑Pacific theater. The command will continue running operational tests to observe how the Bitcoin protocol behaves under different network conditions and to evaluate potential applications for protecting military and critical infrastructure systems.
