I2P, the invisible internet protocol allows for anonymous torrenting (getting movies, games, etc. without paying). It’s fairly old and robust, but lacks actual people using it. Now a program that many people already use has included the option to use this.
This alone may increase the usage of this system, and make it more useful.
I mean, this is the first implementation in qbittorrent.
Imagine if at some points it ships a complete implementation by default, and everyone using qbittorrent could be reached via i2p. We’re not there, and not terribly close, but implementing i2p was an important step to get there.
