The darknet doesn’t rely on conventional search processes; as I understand it, it’s more like finding blogs on specific subjects, and asking for required info or items, although I could be off the mark
You’re broadly right, aye.
Tor is the way, it’s a slow version of the normal internet.
TOR is synonymous with the hatefully-named “dark web” but really it’s nothing to do with it. TOR simply provides a degree of anonymity.
As an analogy, let’s use the phone system. You want to know the number of a plumber, you look in the phone book under “plumbers” and then dial the number. You want to know the number of your local drugs dealer, you look in the Yellow Pages and find to your surprise that there’s nothing there.
So you ask your mate Dodgy Dave if you know where you can get some drugs. He goes, aye, sure, and gives you an ex-directory phone number for Shady Sean. This, in essence, is the dark web.
You ring Shady Sean, and order a bag of something illicit. Except, the phone company now have a record of you ringing him (assuming they haven’t blocked you from ringing ex-directory numbers). The police have been keeping an eye on Shady Sean and now they know you’ve been talking to him. They get onto BT, and BT give them a copy of the transaction, and both Sean and you get busted.
So instead of doing that you dial 141 and then a number at random. Someone in France picks up, “bonjour?” she says. You give her Sean’s details and ask her (in your best French) to dial another random number and pass on the details. After half a dozen iterations of this, someone actually rings Sean and gives him your order. This, in essence, is TOR.
