I read a couple of years of an article about this, where I had the same thoughts, that Block Chain is a new Internet.
The article on the example was told about the possible future, when all the information about a person (documents, bills, diplomas, mortgages on the house, etc.) is recorded in the bitcoin address. Thus, natariuses, realtors, managers and many other professions that are intermediaries in the sale and purchase or execution of transactions will not be needed.
