A U.S. Navy Admiral stated that Bitcoin's PoW technology can increase the cost of cyber attacks and support national security strategies

According to Cointelegraph, Admiral Samuel Paparo of the U.S. Navy stated at a Senate Armed Services Committee hearing that Bitcoin is a "valuable computer science tool," and its proof-of-work technology has significant applications in cybersecurity, increasing the cost of attacks for adversaries and can be used to protect data, information, and command signals, helping to support U.S. national security interests.

Paparo noted, "Beyond the economic aspect, it has very important computer science application value in cybersecurity." Previously, Jason Lowery, a member of the U.S. Space Force, also made similar points in 2023.
