Magnetic link is a link that does not refer to source files, but confirm the authenticity of the file is downloaded. Magnet technology is interesting only link to sites like The Pirate Bay.


BitTorrent is one of the largest networks of P2P (Peer-to-Peer), through which users can exchange information (files) between them. For BitTorrent network type, it is necessary that certain sites (like The Pirate Bay) to provide a degree of coordination, since the protocol itself does not include any mechanism for searching for files. For this reason, a tracker operator operates on servers that manages and distributes addresses to users as soon as they integrate into the network.

To find a file, the user installs a client like μTorrent and download a file from the torrent sites. This establishes a link with the client and the file search process starts with the tracker, which transmits the source IP addresses. Once the download starts, even the user is included as a source file. This is why the tracker is the central interface, which forwards the download links, and this was the Achilles heel in the case of The Pirate Bay.

With magnet link mechanism changes because it is similar in some degree a URL (Uniform Resource Locator) standard. However, unlike a traditional URL, it does not show any source of download: magnet link only confirms that we are dealing with a file that fits exactly at the link - completely independent of the location of the upgrade. For this purpose, an algorithm generates a hash value of file type. Value is just a brand and an order number that does not compromise the information in the file, but only serves to identify it. The user alone must try to find where the.
For those who maintain the server is a major difference, considering that in this case is no longer necessary to maintain a tracker. The website should provide only a filename and a corresponding hash value.


If a user clicks on a magnet link, opens client, just like the torrents. For the program to know (without details on IP addresses) where the file is used so-called protocol DHT (Distributed Hash Table). Each user is allotted P2P neighbors. Link is from a neighbor until another source is found - is a resource intensive method that works completely decentralized.

Eventually, the user does not matter so much if you download a file via torrent or magnet link, for his address (IP) is identifiable as before - for users who offer copyrighted content risks are the same as the technology trackers. In addition, even with a small magnet link disadvantage, because during the search of an IP right is greater than torrents. Several websites such as taking care of the problem Freebase.be time adding link certain information that is similar to the tracker. Here's a torrent saves his coded address for seven days. Each leecher who download a file specific to a database link reaches the freebase.be and is in turn a source for that file, for a week.


To install a magnet link for you is quite simple. Those wishing to exchange data via the need to install such a client such as Phex and export files as magnet links (which can then further be sent by e-mail). Link is independent of location and connection to a server and that is not strictly necessary. Operation of file sharing takes place entirely at the user level. Unlike torrents, which lose their validity if the user is no longer accessible, the magnet link data can be transmitted and exchanged in the network as long as someone has them. For suppliers of content is a convenient method of distribution: they are not forced to maintain expensive server to distribute data - a magnet link will be enough, be posted on a blog. Users will provide the necessary infrastructure on themselves in the P2P network.
