[citation needed] In 2014, with the release of version 6.3.1, a custom built-in onion routing network was introduced as part of Tribler.

[9] Users can load any clearnet torrent, and by leaving the box for anonymity ticked, the files will be routed through other Tribler.

[10] Because the custom onion network does not use Tor exit nodes, it is enhanced to make every Tribler user to function as a relay.

Tribler borrows bandwidth capacity from connected nodes regarded as helpful to boost the download speed of files.

[14] Tribler is designed to enhance BitTorrent by removing the need for central elements such as the websites for finding content, as well as being anonymous.

[15] After a news article on TorrentFreak in February 2012 mentioned Tribler's decentralization and the fact that its index is impossible to take down, the website became hugely popular, causing it to be reduced to just the download page to satisfy demand.
