OK, but I first have to read their proposals a bit more thoroughly. Allow me a couple of days for that I would also add Maidsafe, Akasha, and ZeroNet, maybe even Synereo, Steem, Datacoin and Agoras/Tauchain; and Freenet as a "blockchainless" and older competitor.  Most of them are still in planning/testing stage, Shift may be already functional, but I'll have to try it.

I think I've found the error with the demo site: the webtorrent.io tracker doesn't exist anymore (the other trackers, however, should work; but they [still?] don't know the torrent), and maybe the tracker list I used is outdated. Will check it again, probably tomorrow at night, if it cannot be accessed until then.

The demo page is now seeding 24/7, and Fuseki is also running 24/7, but still not updating its RDF blockchain in real time (it sits now on block 1205200 approx).

@ksdme, your transaction is found now, but the hash seems a bit short; I think you omitted the "magnet" part of the link, so the JS app "cut" a part of it. In my opinion this is a bug; it shouldn't matter if you include the magnet identifier or not. One could, however, argue that the magnet "prefix" would make it possible to distinguish torrent hashes from other data formats.
