Nxt now has the "Data Cloud" feature on mainnet (with NRS 1.7.3e).
This feature allows to upload lightweight data files directly to the blockchain. The files are also very easy to upload, download and search. As an example, this feature is perfect to put torrent files onto the blockchain.
https://nxtforum.org/nrs-releases/nrs-v1-7-3e/So you just store magnet links to torrent data which is served up like a p2p bittorrent network? How is that different than what these other projects are doing but they also include ability to sell storage space?
In the end you may have a case where you need some information that you dont have stored and its not on the cloud anymore all you have is a magnet link with no peers. Is this correct?
As far as I understand, it can be used with magnet link where DHT network is used. If there is no peer, of course the file cannot be retrieve. Im not expert in torrent, I was just giving an example. In fact, I'm not sure to understand your question.
The Data Cloud feature allow you to upload any small file on the blockchain (not just torrent). Here is a screen shot since an image worth a thoushand words:

Note also that this is the first version of the GUI.
For more information, I suggest you try the client (1.7.3e) or ask question directly on the forum in this topic:
