The United States Department of Defense (DoD) is going to use blockchain solutions for cybersecurity as part of its digital modernization strategy. The DoD research branch, the Defense Advanced Research Projects Agency (DARPA), is working on two exploratory blockchain projects focused on cybersecurity. The first project of DARPA is experimenting with blockchain to build a new or improved platform for communication and transaction. And the second project is an attempt to create an “unhackable code” through blockchain technology that will prevent to hack the database.
