What is Dark Web? How to access dark web?

Deep Web, also known as “Deepnet,” the “Invisible Web,” the “Undernet” or the “hidden Web,” are parts of the Internet that are not considered part of the “surface web,” or the portion of the World Wide Web that is indexed by conventional search engines. Many deep web sites are not indexed because they use dynamic databases that are devoid of hyperlinks and can only be found by performing an internal search query.

The dark web is the World Wide Web content that exists on darknets, overlay networks which use the public Internet but require specific software, configurations or authorization to access.The dark web forms a small part of the deep web, the part of the Web not indexed by search engines, although sometimes the term "deep web" is mistakenly used to refer specifically to the dark web.

The darknets which constitute the dark web include small, friend-to-friend peer-to-peer networks, as well as large, popular networks like Tor, Freenet, and I2P, operated by public organizations and individuals. Users of the dark web refer to the regular web as Clearnet due to its unencrypted nature. The Tor dark web may be referred to as onionland, a reference to the network's top level domain suffix .onion and the traffic anonymization technique of onion routing.

Darknet websites are accessible only through networks such as Tor ("The Onion Router") and I2P ("Invisible Internet Project"). Tor browser and Tor-accessible sites are widely used among the darknet users and can be identified by the domain ".onion". While Tor focuses on providing anonymous access to the Internet, I2P specializes on allowing anonymous hosting of websites. Identities and locations of darknet users stay anonymous and cannot be tracked due to the layered encryption system. The darknet encryption technology routes users' data through a large number of intermediate servers, which protects the users' identity and guarantees anonymity. The transmitted information can be decrypted only by a subsequent node in the scheme, which leads to the exit node. The complicated system makes it almost impossible to reproduce the node path and decrypt the information layer by layer. Due to the high level of encryption, websites are not able to track geolocation and IP of their users as well as the users are not able to get this information about the host. Thus, communication between darknet users is highly encrypted allowing users to talk, blog, and share files confidentially.

Darknet markets

Commercial darknet markets, which mediate transactions for illegal drugs and other goods, attracted significant media coverage starting with the popularity of Silk Road and Diabolus Market its subsequent seizure by legal authorities. Other markets sell software exploits and weapons. Examination of price differences in Dark web markets versus prices in real life or over the World Wide Web have been attempted as well as studies in the quality of goods received over the Dark web. One such study performed on the quality of illegal drugs found in Evolution, one of the most popular crypto markets active from January 2014 to March 2015. An example of analytical findings included that digital information, such as concealment methods and shipping country, seems accurate," but the illicit drugs purity is found to be different from the information indicated on their respective listings." Less is known about consumer motivations for accessing these marketplaces and factors associated with their use.
