Maybe you could use erasure coding instead of replication so that dedupe isn't possible. There's still a Sybil attack where multiple blocks end up getting deleted by the same peer.

You have to make sure that somehow the person storing the erasure codes can't first deduce the original data, and then from this regenerate the erasure codes. Maybe that is not a hard problem?
