The U.S. military has officially acknowledged operating a node on the Bitcoin network for the first time.

On April 22, 2026, during a hearing of the U.S. House Committee on Armed Services, Indo-Pacific Command commander, Admiral Samuel John Paparo Jr., was asked about the national security value of digital assets and gave an answer that surprised most people.

“Right now, we’re in the experimental phase. We are running a real-time node on the Bitcoin network. We are not mining Bitcoin. We use it to monitor, and we’re conducting multiple operational tests to leverage the Bitcoin protocol to protect and harden networks.”

This was the first public admission by an active-duty U.S. combat command that it directly connects to the Bitcoin peer-to-peer network.

Key follow-up questions in the hearing

The day before the hearing, at the Senate Armed Services Committee hearing on April 21, Paparo said that Bitcoin shows enormous potential as a tool for computer science. Through a proof-of-work protocol, it essentially imposes higher costs on attackers than purely algorithmic security. In essence, it is a peer-to-peer, zero-trust value transfer network. At that time, he did not disclose any specific actions.

The next day, at the April 22 hearing, Texas Republican Congressman Lance Gooden asked—using data comparisons of China- and U.S.-held Bitcoin—whether the U.S. should maintain a leading edge in Bitcoin, the same way it treats gold and oil.

Only then did Paparo reveal the details of running the node.

What’s especially notable is that across these two days of hearings, Paparo never mentioned reserve assets, and he also did not mention prices at all. His framing was entirely about cryptography, blockchain, and proof-of-work—a set of pure computer science language, not financial language.

What does running a node mean?

A Bitcoin node is a computer that runs Bitcoin software. It synchronizes the full blockchain data, independently verifies every transaction and every block on the network. It does not produce Bitcoin, and it does not handle users’ funds. Instead, according to the rules of the protocol, it checks and determines whether data is correct, transmitted, or accepted.

Globally today, there are approximately 15,000 to 20,000 publicly accessible full nodes. In addition, there is an unknown number of nodes that are not visible from the outside and operate behind firewalls. The Indo-Pacific Command’s node is one of them—neither special nor endowed with any additional privileges within the network.

According to real-time data from Bitnodes, as of April 27, 2026, the number of publicly accessible full nodes is about 24,000. The Indo-Pacific Command’s node simply gives the military a first-hand, zero-trust data perspective, and the influence of any single node on the overall network is nearly zero.

But what a node can provide is something else: a first-hand data perspective. Operators can monitor the mempool (the pool of unconfirmed transactions) in real time, observe parts of network topology, and directly access on-chain data without depending on any third-party service.

The “monitoring” Paparo mentioned likely refers to this layer, rather than getting second-hand queries through analysis providers such as Chainalysis, in order to give the military a zero-trust data observation post.

The boundaries of a node are clear. It cannot see users’ real identities, cannot selectively intercept any transactions, and cannot modify or control the network. Bitcoin’s consensus mechanism means the influence of a single node is almost negligible. Paparo’s wording was “the experimental phase,” not deployment or operation.

At the hearing, he also said that the PoW protocol imposes higher costs on attackers. This is describing the attack-resistance characteristics intrinsic to the Bitcoin network itself. The military is testing whether this mechanism can be adapted for defense design in military networks. This falls under research at the protocol level, not direct operation of the network itself.

Three different ways of handling it

Bitcoin has never been a single, unified voice within the U.S. government.

The logic of the Department of the Treasury and OFAC is sanctions and compliance: focusing on tracking the flow of funds, blocking channels used to evade sanctions, and treating Bitcoin as something monitored in that framework—an object to be watched. The SEC’s role is to determine asset characteristics. After the approval of ETFs, Bitcoin is closer to a financial product in regulatory terms.

This time, the military’s stance takes the third path: treating the Bitcoin protocol as a technological infrastructure to be studied. That is completely different from the starting points of the first two departments.

At the hearing, Paparo supported the GENIUS Act and said he supports anything that would help maintain the dollar’s global dominance. As a result, the military’s technical experiments were framed within the direction of the broader U.S. financial strategy, but at the implementation level, each department still runs along its own track.

In China, the picture is different. Restrictions on trading and mining have been enforced for years. At the same time, the consortium blockchain technology and digital renminbi system are taking the route of developing controllable blockchain applications, while open crypto assets are excluded.

The divergence between the two countries in their digital infrastructure approaches also forms the background for questions at this hearing of the military committee: whether the U.S. should maintain a leading edge in Bitcoin, the same way it treats gold and oil.

And just around the same time as Paparo testified to Congress, in April 2026 during the Iran–U.S. ceasefire, Iran began charging tolls on fully loaded oil tankers passing through the Strait of Hormuz. The standard was about $1 per barrel of oil, and payment was required in cryptocurrency. Bitcoin is listed as one of the official payment options.

Reports from blockchain analytics firms TRM Labs and Chainalysis show that since mid-March, the Islamic Revolutionary Guard Corps has been collecting tanker tolls through intermediaries. Payment methods include RMB, Bitcoin, and stablecoins, with stablecoins actually processing most of the funds.

Iran’s holdings of crypto assets reached about $7.8 billion in 2025. On April 24, the U.S. Treasury announced sanctions on multiple Iran-related crypto wallets. Tether subsequently froze two Tron network addresses, totaling about $344 million USDT. At this stage, BTC and USDT can be viewed as extensions of dollar hegemony.

Compared with the U.S. military running nodes, this is a completely different use case. The U.S. military is doing technical observation and protocol testing, while Iran is using Bitcoin and stablecoins to bypass SWIFT and the dollar settlement system—turning the Strait of Hormuz’s passage right into on-chain income.

One is about entering the network; the other is about completing transactions through the network. Two nearly simultaneous things, yet serving entirely opposite purposes.

Still evolving

After Paparo’s hearing, the crypto community’s reaction was mainly positive. Bitcoin saw a slight uptick that day, briefly breaking above 7.7w dollars, but it did not trigger a frenzy. This also suggests that market sentiment is maturing, increasingly treating recognition of this kind of technology as the norm.

However, the amount of information currently available is very limited. Details such as running several nodes, what specific tests are being conducted, and whether on-chain analysis tools have been integrated have not been made public.

Paparo repeatedly emphasized the experimental phase. And in the FY2027 National Defense Authorization Act, which is being pushed forward in Congress by Congressman Gooden, the discussion on digital assets is still stuck in legislative limbo.

The U.S. military’s approach to the internet, the Global Positioning System, and onion routing networks has always been to start with military testing and then spill over into civilian use. Bitcoin, this time, appears to be following a similar early-stage path.

First, the military is taking it seriously as a computer science infrastructure for research. As for whether this will eventually profoundly affect broader strategies for network warfare, it still needs to be observed over time.

Zooming out further, over the past two years Bitcoin has been showing up in an increasing number of contexts that previously seemed unlikely: ETF discussions, debates about national strategic reserves, stablecoin legislation, military committee hearings, and tolls in the Strait of Hormuz.

Based on each country’s and institution’s own needs, they are approaching the same set of protocols in their own ways.
