I serisouly don’t understand what blossom does. I don’t believe it saves the files. It just saves the hash of the file if I understand correctly. There are much smarter people here on nostr than my self to answer this question.

As for the media. I believe with less than 200K Sats you can build an Umbrel and open it to the public with TOR if you want.

You can host a word press site on it. It can also host files. But I have not tested this, although seems possible.

Question is, can bandwidth handle it. Probably not.
