Seems like this could be a common use case for pirates. Similar to how Megaupload or Fileshare worked a few years ago.

Sia's encryption doesn't protect the file hosts, if the uploader posts a link + decryption keys for pirated content to a public file sharing forum.

Does the take down notice go to everyone that hosts a fragment of the file? Who is liable if the uploader can't be traced?

Good question.

I suppose that would only work if whatever keys the pirate needed to publish to allow the data to be downloaded wouldn't _also_ give the keyholder the ability to delete that data. Otherwise the copyright holder could just issue the command to delete the file themselves. I'm not sure if Sia works that way or not; would be interesting to see.

Since they say their intent is to compete on price with S3 / CDNs, it seems possible to be able to download a file without having permissions to delete that file. If that were not the case, then Sia would be limited to personal backup only.

It's confusing, because they refer to themselves as a potential competitor to S3 several times in the linked article, but I thought I read somewhere that conceptually what they're building is actually just the data persistence layer of a service like S3?

A complete S3-like service would require a third-party tool on top of Sia. Goobox[1], for example, uses sia as a storage backend and provides an S3-compatible API[2].

In other words, right now - I think if you are interacting with Sia directly you can do whatever you want with the files you have access to. Not 100% sure about that.

A complete S3 service on top of Sia is what SiaPrime[0] is doing.
