U.S. Space Force Maj. Jason Lowery urged the Department of Defense to conduct a thorough investigation of Bitcoin's Proof of Work (POW) protocol. This is because he believes that it can be used as part of the country's protection strategy.

Lowery sent an open letter to the U.S. Defense Innovation Council
in which it calls for the adoption of POW to prevent future attacks, thus keeping the peace for a long period of time, as much as possible.
In the letter, shared on X by bitcoiner Dennis Porter, Bitcoin is described as a pioneering network that has the potential to turn the world's power grid into a large, physically expensive computer, or 'macrochip'.
"The Bitcoin protocol can be used to restrict malicious actors and safeguard a wide range of data and messages traversing the internet," Lowery added.
The proposal is to use a model based on Bitcoin's POW to deter adversaries from carrying out cyberattacks, due to the "high costs" of a computer that requires a lot of physical resources, in the same way that military assets help deter attacks against the country.
Lowery points out that the way the Bitcoin network is safeguarded aligns "perfectly with a strategic trade-off" and that the U.S. Department of Defense may have already "lost valuable time" by not implementing it in its arsenal.
