Being completely anonymous on the Internet is almost impossible, but you can be almost anonymous via the Onion Routing tool.
Onion Routing Basics Guidance:
One way to understand onion routing is to start with the concept of proxy servers. A proxy server is a server that connects your connection through this server ...., which basically adds a step in the path of your data packets. If someone tracks your IP address, they'll see a proxy address instead of the proxy server
But proxy servers are not completely anonymous, they keep records of all traffic passing through them, which means they can actually refer you back if necessary, but not to disclose your identity will not be guaranteed.
What is Onion Routing, exactly?
Onion Routing is like an advanced form of proxy routing. Instead of routing through a single unprotected server, it uses a network of nodes that continuously encrypts your data packets at every step, only at the end of this "chain" of onion layers, It is attributed to onions because it has many packages that you can consider as the continuous encryption process that protects your data inside. Due to the multiple layers of encryption, which are not coincidental-like layers within the onion, it is extremely difficult to keep track of your information when using the onion directive.
Simple example:
Have you ever heard of TOR? It's a safe network that uses onion guidance to keep your activity encrypted and hidden. You must now understand what his symbol is like the bulb.
