As TFA mentions, this works fine for private storage, but we're trying to incentivise people to back up publicly accessable data like the blockchain or chunks of the internet archive. We want a way for possibly-malicious servers to prove that they're storing distinct bottom-layer encodings of data they do know is the same.

Then you ask for random segments and either the file is stored, or the cheater would need to re-encrypt a large file over and over, which would be much more expensive than storage. (and if it's not more expensive, make the files larger, the requests more often, etc...)
