Tribler uses Tor-inspired onion routing to search and download torrents with fewer worries or censorship. Tribler is a social community that facilitates file sharing through a peer-to-peer (p2p) network.
When the Tribler application program is started it will automatically start searching other users that have Tribler running on their computer. When a connection is established it starts exchanging information.
First it exchanges personal information (such as your avatar picture, your friends list, download history, etc.) and information about files that are available in the network. These files can be personal, shared files, but also files that one has received from another person.
