Blockchain has the potential to transform business and government.  It is not disruptive technology.  It is transformative technology just like TCP/IP laid the transformation of the internet in 1972 and it took 30 years, thereafter, for email to gain critical mass. 

"If bitcoin is like early e-mail, is blockchain decades from reaching its full potential? In our view the answer is a qualified yes. We can’t predict exactly how many years the transformation will take, but we can guess which kinds of applications will gain traction first and how blockchain’s broad acceptance will eventually come about."  Harvard Business Review, Jan. 2017.
