I was just thinking. that the verify that the object is original feature of the upcoming blockchain could be useful for free objects. I imagine this could be by making the signing key public so that anyone can. But this would require that the signing new object key would be different from the author key and the transfer ownership of the signing key to a new key key.
There’s no reason why they would have to be separate. There’s a multitude of ways to handle this with cryptography.
