Tribler is a research project of Delft University of Technology. (...) Tribler is the first client which continuously improves upon the aging BitTorrent protocol from 2001 and addresses its flaws. We expanded it with, amongst others, streaming from magnet links, keyword search for content, channels and reputation-management. All these features are implemented in a completely distributed manner, not relying on any centralized component. Still, Tribler manages to remain fully backwards compatible with BitTorrent.
I worked on an anonymous P2P research project many many years ago now, and we were shocked when we saw how much funding they received compared to us (3 mil EUR!) - but I'm super happy to see that their project is still alive and kicking! I guess the money was put to good use.
