For a technology that spent years being dismissed by government officials as a tool for criminals and speculators, Bitcoin just got a very different kind of endorsement.
Admiral Samuel Paparo, commander of US Indo-Pacific Command (INDOPACOM), the military’s largest combatant command, responsible for American forces across the Asia-Pacific region, confirmed this week that the US government is actively operating a node on the Bitcoin network.
Not to accumulate the asset. Not to mine it. To study what the underlying protocol can do for military network security.
The disclosure came across two days of congressional testimony. On Tuesday, Paparo appeared before the Senate Armed Services Committee during a hearing on the fiscal year 2027 defense authorization, where Senator Tommy Tuberville pressed him on whether American leadership in Bitcoin gives the US an edge against China in the Indo-Pacific.
The following day, Congressman Lance Gooden drew out the node confirmation during a House Armed Services Committee session, producing what appears to be the first public acknowledgment that a US military combatant command is directly participating in the Bitcoin peer-to-peer network.
Paparo’s answer to Gooden was unambiguous. “We have a node on the Bitcoin network right now,” he told the committee. “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.”
What a node actually is and why it matters here
To understand what the military is doing, it helps to separate the node from the mine. A node, in Bitcoin terms, is a computer that holds a full copy of the blockchain and participates in verifying transactions against the network’s rules. Nodes don’t create new Bitcoin, they don’t earn rewards, and they don’t require the industrial-scale energy consumption associated with mining.
As of early 2026, there are an estimated 15,000 to 20,000 publicly reachable full nodes on the Bitcoin network, though the real count is almost certainly higher since many nodes operate behind firewalls and remain invisible to outside scans.
Running one node among tens of thousands poses no practical threat to Bitcoin’s independence or its decentralization. The network is specifically designed so that no single participant, government or otherwise, can exert meaningful control by joining it. That design principle is exactly why the disclosure is notable without being alarming.
The US military has parked itself inside the world’s most decentralized financial network and is watching how it works from the inside. That’s a very different posture from the skepticism and outright hostility some government agencies directed at crypto in years past.
Paparo was careful to frame the entire project in technical rather than financial terms. “Our research into Bitcoin is as a computer science tool,” he told the Senate committee. “It’s the combination of cryptography, a blockchain, and a proof-of-work.”
Proof-of-work is the consensus mechanism, the method by which Bitcoin reaches agreement on which transactions are valid, that requires enormous amounts of real computation to function.
The cost is the point. Any actor trying to attack or rewrite the network has to match the combined computing power of every honest participant. That property, Paparo suggested, has direct applications to thinking about how adversaries can be made to pay real costs in cyberspace.
Space Force Major Jason Lowery, a national defense fellow at MIT, has spent years making a version of this argument, that Bitcoin’s proof-of-work mechanism can deter cyberattacks by imposing physical, energy-based costs on adversaries in a way that purely algorithmic security cannot replicate. Paparo’s testimony suggests that line of thinking has found an audience at the command level.
Dollar dominance and the bigger picture
What made Paparo’s testimony unusual was the range of the argument he was building. He moved from network security to currency strategy within the same exchange.
When the conversation turned to dollar hegemony, the idea that maintaining the US dollar’s status as the world’s reserve currency is itself a national security objective, Paparo connected it directly to digital assets.
He pointed to the GENIUS Act, legislation signed by President Donald Trump last summer that created a legal framework for dollar-backed stablecoins, cryptocurrencies whose value is pegged to the US dollar, as a positive development for American financial reach. “A great step forward that moves us in that direction,” was how he described it.
That framing matters. It positions stablecoins as an extension of dollar dominance in a world where digital payments are increasingly global and decentralized.
The Bitcoin Policy Institute noted that Iran has accepted Bitcoin for transit tolls in the Strait of Hormuz, while Taiwanese policymakers have discussed Bitcoin as a potential reserve asset, a hedge against wealth confiscation in the event of a Chinese military move.
Paparo did not address the Trump administration’s Strategic Bitcoin Reserve, the proposal to have the US government formally accumulate Bitcoin as a national asset, during his open testimony. He confined his remarks to INDOPACOM’s existing technical research and indicated that some details of that work may remain classified.
