The U.S. military has confirmed its active participation in the Bitcoin network, marking a significant shift in its approach to cryptocurrency. Admiral Samuel Paparo, Commander of the U.S. Indo-Pacific Command, testified before Congress that the command is operating a Bitcoin full node and conducting cybersecurity tests based on the Bitcoin protocol. Paparo described Bitcoin as a "computer science tool" and a "means of power projection," emphasizing its potential beyond financial speculation. During Senate and House Armed Services Committee hearings, Paparo highlighted Bitcoin's strategic value, particularly its proof-of-work mechanism, which he noted could be leveraged for both offensive and defensive cyber operations. This marks the first instance of a U.S. military command publicly acknowledging direct involvement in Bitcoin's peer-to-peer network. Paparo's testimony underscores a narrative shift, framing Bitcoin as a technology with national security implications rather than a financial asset.
