The US military is running a live node on the Bitcoin network and testing the protocol as a cybersecurity and power-projection tool, the commander of US Indo-Pacific Command (INDOPACOM) told Congress on Wednesday.
Admiral Samuel Paparo disclosed the program during a House Armed Services Committee hearing on April 23, 2026, responding to questions from Rep. Lance Gooden (R-TX). It marks the first time an active-duty US military commander has publicly acknowledged the Pentagon’s participation in the Bitcoin network.
A Bitcoin node is a computer that maintains a full, independent copy of the Bitcoin blockchain, verifying every transaction without mining new coins or controlling any funds.
- INDOPACOM is operating a live Bitcoin node for cybersecurity testing, Admiral Paparo confirmed to Congress on April 23, 2026 — the first public acknowledgment by an active US military commander.
- The military is not mining Bitcoin. The node is used for monitoring and operational testing of network security applications.
- Paparo described Bitcoin’s architecture as “cryptography, a blockchain, and a reusable proof-of-work” with “huge potential” for securing US networks against adversaries including China.
- Some details of INDOPACOM’s Bitcoin research remain classified, Paparo said.

From skeptic to operator
The disclosure represents a notable shift in how senior US military officials frame Bitcoin. Paparo, who has previously expressed skepticism about cryptocurrency’s role in national security, now describes Bitcoin’s underlying architecture as a tool with strategic value — distinct from its use as a financial instrument.
“We have a node on the Bitcoin network right now,” Paparo told the committee. “We’re not mining Bitcoin. We’re monitoring, and we’re doing a number of operational tests to secure and protect networks using the Bitcoin protocol.”
The framing throughout his testimony was technical, not financial. Paparo described Bitcoin’s value as its combination of cryptography, a distributed blockchain, and reusable proof-of-work — an architecture built for integrity, transparency, and resistance to tampering. He did not specify which network security applications are being tested, and said some program details remain classified.
The China angle
The geopolitical framing was explicit throughout Paparo’s testimony. He repeatedly connected Bitcoin research to great-power competition with China, describing the protocol as a potential “additional tool to secure networks, and to project power.”
China has banned domestic Bitcoin activity while building state-controlled digital infrastructure, including its central bank digital currency and a state-dominated payments architecture. According to CoinDesk, INDOPACOM’s research centers on Bitcoin as a computer science tool — its censorship resistance and permissionless design seen as strategic assets in adversarial network environments where centralized systems carry single points of failure.
That framing positions Bitcoin’s decentralization as a feature, not just for financial freedom, but for military network resilience in contested domains.
What comes next
Paparo said INDOPACOM remains in an “experimentation phase.” The program is a test, not a deployed system. But a public disclosure to Congress typically signals that research has cleared internal credibility thresholds.
If results from INDOPACOM’s testing show the Bitcoin protocol can improve network security outcomes, other commands and agencies could launch similar programs. The Block noted that there are an estimated 15,000 to 20,000 publicly reachable full nodes on the Bitcoin network today, with the actual count likely higher given nodes that run behind firewalls. INDOPACOM’s node adds to a network already secured by tens of thousands of independent operators worldwide.
For the regulatory picture, Wednesday’s testimony adds a new dimension. Congress has long debated how to classify Bitcoin. Paparo’s framing introduces a national security argument that transcends the financial classification debate, which could give legislators in both parties new reasons to approach Bitcoin policy differently than altcoins and DeFi tokens.
FAQ
What is the US military doing with a Bitcoin node?
INDOPACOM is running a full Bitcoin node to monitor the network and run operational tests on using the Bitcoin protocol to secure military communications and networks. The military is not mining Bitcoin or treating it as a financial asset. The focus is on Bitcoin’s cryptographic architecture and distributed ledger as a security technology.
Does this mean Bitcoin is becoming part of US military infrastructure?
Not yet. INDOPACOM is in an “experimentation phase,” Paparo said. The program is a research and testing initiative, not a deployed operational system. Paparo acknowledged some details remain classified, which suggests the program may be more developed than the public disclosure indicates.
Why does the US military care about Bitcoin specifically, rather than other blockchains?
Paparo cited Bitcoin’s specific combination of cryptography, proof-of-work, and decentralization rather than blockchain technology generally. Bitcoin’s network is the largest, most decentralized, and most battle-tested blockchain in terms of attack resistance — properties that matter more for security applications than transaction speed or programmability.
