The governor's office of North Dakota announced a deal that will see the company Bitzero Blockchain turn a relic of the Cold War into a "highly secure data center for high-performance computing and data processing."

The site, known as The Pyramid, was part of a 1970s effort to protect US military bases from Soviet attack, according to the State Historical Society of North Dakota. The Stanley R. Mickelson Safeguard Complex is "a huge concrete pyramid which housed the men and equipment that protected the Grand Forks Air Force Base missile field from possible attack by Soviet missiles." The only installation of its kind, it controlled dozens of anti-ballistic missiles but remained in operation only eight months in 1975.

"We are deeply grateful for Bitzero's significant investment in our state and for the tireless efforts of the North Dakota Department of Commerce and Cavalier County Job Development Authority to secure a viable tenant and seize the potential of this historic structure," Gov. Doug Burgum said in prepared remarks.
