Torrents are ephemeral. The persistence provided by a blockchain is totally overkill and comes at a very high cost in resources. Blockchains also don't inherently provide strong sender anonymity. That would have to be built on top. I think Riffle may be the most sensible option I've seen for sharing magnet links or torrent files. In theory, Riffle doesn't require a large number of servers and doesn't demand unreasonable client bandwidth to deliver protection against a very powerful adversary. It's just an academic system with a basic proof of concept implementation. Quite a bit of work needs to happen to turn it into a usable system. For the data itself Riffle is too expensive. Something with a weaker threat model that costs less resources is needed, such as Aqua or Herd. Those systems are also academic at this point.
