Tor, as it is known, is primarily used to provide anonymity while using the Internet, and to provide protection and safety of the user.
With Tor you can not only surf the Internet anonymously, but also use internet messaging, IRC, SSH, a variety of other software products that use the TCP protocol. A developer can make new applications on TCP platform. Anonymity and all the necessary elements for the privacy will be built in automatically. You will also be able to view those sites which, for one reason or another, have recently been "closed". Formalists of "Roskomnadzor" sometimes block individual sites, although they do not constitute a threat and contain a lot of useful information for the visitor of the Internet at the same time.
How is anonymity provided in Tor? Due to constant changes of connection inside the distributed network of servers. They are called onion routers. The path from the source to the destination when using Tor is not a straight line - it is much longer than with the usual connection. And this path is completely random, passes through several servers, thereby it is almost impossible to track the movement.
Moreover, even the onion routers are not able to give a clue who you are and where you are now. Tor is the best defender from the traffic analysis. Exactly this form of network surveillance is the greatest threat to user privacy. Therefore, you can easily maintain the confidentiality of your business activity, your relationship with other online visitors.
Every day traffic analysis is applied by different companies, government, and some people who need to keep track of what sites people visit, for what purpose. For example, it may be used to impose aggressive advertising or to take even more dangerous actions.
By the way, when you use Tor, you always have a choice - if you wish, you can remain anonymous, if not - you can identify yourself.
