- Admiral Samuel Paparo told lawmakers on April 21 and April 22 that Bitcoin has cybersecurity value and that the military is already running a node.
- Paparo said the node is not mining Bitcoin, but is being used to monitor the network and conduct operational tests to secure and protect systems.
- Critics including Matthew Kratter and Lola Leetz said the public explanation was too vague, raising fresh doubts about how deeply officials understand Bitcoin.
Admiral Samuel Paparo’s Senate testimony and House remarks pushed Bitcoin into the US national-security debate again. This came after he framed the protocol as a tool for “cyber defence” and said the military is already running a node to test network protection use cases.
The strongest published primary-source record came from a House Armed Services Committee exchange released by Congressman Lance Gooden on April 22.
In the transcript, Paparo said the US interest in Bitcoin is rooted in “cryptography, a blockchain, and reusable proof of work” and added that the protocol has implications for securing networks and for “projection of power” from a computer-science standpoint.
Paparo then said the military already has a node on the Bitcoin network, but is not mining. Instead, he said the node is being used to monitor the network and conduct operational tests aimed at securing and protecting systems.

Critics Call Explanation Thin
That explanation immediately drew skepticism from parts of the Bitcoin community. Bitcoin educator Matthew Kratter said on X that Paparo sounded like he was reading from the Bitcoin “Wikipedia page” and argued the exchange showed the officials involved were talking around the subject rather than explaining it precisely.
Kratter also described the remarks as “actually pretty embarrassing,” according to public reporting that cited his post. Journalist Lola Leetz separately described the testimony as “babbling,” capturing a broader frustration among critics who felt Paparo invoked Bitcoin’s buzzwords without clearly identifying why operating a node would amount to strategic power in practice.
Paparo presented the node as part of an experimentation effort, but his public comments left open how the tests work, what threat models they address and whether the military is studying Bitcoin primarily as infrastructure, intelligence surface or symbolic strategic asset.
