7. The Onion
Router
(TOR)
• TOR is software that installs into your browser and sets up the specific connections you
need to access dark Web sites
• Onion routing refers to the process of removing encryption layers from Internet
communications, similar to peeling back the layers of an onion
• Using TOR makes it more difficult to trace Internet activity
• It is intended to protect the personal privacy of users, as well as their freedom and ability
to conduct confidential business by keeping their internet activities from being
monitored.
• The most infamous of these sites was the now-defunct Silk Road, an online Marketplace
where users could buy drugs, guns and all sorts of other ilegal ítems.

8. Money
transactions• The main problem of buying an selling items or services in this webs is that
users can`t identify each other.
• Bitcoins : A digital currency or crypto-currency that is not backed by any
county`s central bank or government. They can be traded for goods or
services with vendors who accept Bitcoins as payment.
• Like regular cash, Bitcoin is good for transactions of all kinds, and it also
allows for anonymity, that means no one can trace a purchase, illegal or
otherwise.
