The Blockchain against false identities on the Internet

The Blockchain allows to draw a profile (or a digital identity) of Internet users. Reviews, comments and online content sharing are very important, so you have need to know the identity of the users.
Furthermore, the Blockchain may be able to monitor our daily activities. Connected to the data generated thanks to the Internet of Things, it can record and verify customers’ purchasing habits through payment data and if an employee is in the office.
This would avoid the negative aspects of the Internet anonymity: hate speech, threats and impartial information.
The most reliable sites have verification systems (e.g. accounts related to credit cards and social network profiles) and they allow to distinguish the activities carried out by real people from those of the robots through Artificial Intelligence.
