The Blockchain, which I basically call the Operating System of the Society (as well as Windows, Mac OS, Linux, Unix were for computers, and Internet was for access to information and communications), will play a role of construction of new processes and institutions, based on a "decentralization" format, without "private ownership of things".
The Blockchain, what it does, is to ensure trust between two people. Without intermediaries to guarantee it (call it institutions, companies or any other type of centralized association). That is, it will not only transform the Economy and Finance sector, or the "Businesses"; but it will forever change the way we organize ourselves as a Society.
