The United States Air Force has quietly been working on a Bitcoin payment gateway. Through an SBIR or Small Business Innovation Research grant to the Department of Defense, Utica New York based Critical Technologies Inc. has been working on a commercial product for the Air Force since applying for the grant back in 2012 (starting Fiscal Year 2013). Coincidentally, the Bitcoin Foundation began its grant proposal process in 2012 and also awarded its first grant in 2013.
