Hackers have the means to seed their nodes in the Tor network, and security agencies (CIA, GCHQ, FSB, etc.) have even more resources they can devote to putting up their own nodes. Meaning virtually anyone can host a Tor node.

The Tor Project doesn’t buy and maintain the nodes on the network – volunteers do. It’s easy to compromise a volunteer-run network At this point, you might not see it, but the architecture of the Tor network is vulnerable to certain exploits. This allows you to more privately access regular websites as well as specific Tor websites. The Tor Browser periodically switches to a new random circuit of nodes.Incoming data uses the same process, but from the other way around – the exit node is now the entry node, etc.It decrypts the third layer of data to find where to send it – the node can also see the data now The exit node knows that the data is coming from the middle note.It decrypts the second layer to find out where to send the data – what the exit node is The middle node knows that data is coming from the entry node.The entry node decrypts the first encryption layer to find out where to forward the data – what the middle node is

The entry node knows the data is coming from you, but it can’t see what data you’re sending.The Tor Browser forwards the data to the entry node (sometimes called the “guard node”).Any data you send out via the Tor Browser gets bundled into three layers of encryption.The browser creates a circuit of three random Tor nodes.The Tor Browser establishes a connection to the volunteer-maintained Tor network.Aspiring users need to download and install the Tor Browser to access Tor.
