Thanks for the answers, it's helpful. I would say though that for the people who this is most useful for (journalists, photographers, etc) they probably don't want to use it. In order to claim a file they have to send a public tweet for a single file. That's a good way to fill up their feeds with random resources they're using. I think metadata is much more useful for them. That's not to say the blockchain can't be used to great effect, I just think that there should be a more private way to claim resources. (Maybe profiles linked directly to twitter with a history of uploads.) If I just upload something without claiming it first, it's just some numbers. If I claim it separately on the site, it's no better than just uploading the file to my site before anyone else and therefore having the earliest record of use. Maybe this has been considered, I'm only thinking aloud. :p
