Accessing the Dark Web: Tor and Onion Domains

The primary gateway to the Dark Web is the Tor network. Tor (The Onion Router) anonymizes traffic by routing it through a series of volunteer-operated servers, making it incredibly difficult to trace the origin of the connection. The Tor Browser is the most accessible tool for this purpose.

Time marker: 10:20 (What is Tor and the dark web), 10:50 (Tor browser), 12:12 (The next step - onion domains)

These ".onion" addresses are not indexed by standard search engines and can only be accessed via the Tor network. They represent the hidden services, the true digital underbelly.

Historical Context: Silk Road and its Legacy

A significant landmark in the Dark Web's history is the Silk Road marketplace, founded by Ross Ulbricht. It served as a notorious hub for illegal goods and demonstrated the potential for anonymity-driven commerce and, subsequently, law enforcement intervention. Understanding historical cases like Silk Road provides crucial context for the evolution of the Dark Web and its challenges.
