I would imagine that, since the system is going to actively be crawling the Internet for photos in order to protect those already involved, that it will have some way of determining whether new submissions (to their blockchain) will be denied after it is determined that a given photo (or piece of artwork, etc) did not originate from you. We could also imagine that this type of digital accreditation could be used for all other types of media, such as video and text. If we do that, we will be able to determine the order in which content is uploaded to the Internet, so long as that content has any kind of value that differentiates itself from all the noise of the Internet. (such as memes and similar wastes of time)
My opinion is that all blockchain technology that will end up outcompeting the other blockchain technology will outcompete closed source, centralized based blockchain technologies. That said though, this is a brilliant idea from Kodak and they are clearly first actors. However, the brilliance of decentralization is that we will be able to do the same thing as them but better and in a more open (less centralized profitable) way.
I didn't say exactly this in two of my posts, but the idea I'm expressing is similar. I would love to hear your thoughts on them:
