Tribler offers anonymous downloading. Bittorrent is fast, but has no privacy. We do NOT use the normal Tor network, but created a dedicated Tor-like onion routing network exclusively for torrent downloading. Tribler follows the Tor wire protocol specification and hidden services spec quite closely, but is enhanced to need no central (directory) server.
I have no affiliation with the tribler developers. Tribler was developed on a Debian based Linux, and uses ellipic curves in openssl. Because elliptic curves are restricted in the openssl versions that are released with rpm based Linux distributions, I could not run Tribler on OpenSuse Tumbleweed.
I hope that someone will pick up this snap and will be available to improve it and maintain it.
