What is the ksi blockchain?

The KSI Blockchain was invented in the late 1990s / early 2000s by Estonian cryptographers. The first patent was filed in 2002 and it was launched in early 2008 in an initial pilot for the Estonian Government. Since 2012, all transactions between the different databases of the various Estonian administrations are secured via the KSI Blockchain. The technology has been accredited by three major governments for deployment on government networks and secures billions of documents, not only for the Estonian Government but also for other public and private entities around the world including the North Atlantic Treaty Organization (NATO), the U.S. Department of Defense, Lockheed Martin, Boeing and Ericsson.
