It's a great idea with a lot of utility, but my question is: How does dispute resolution work? I.e. How do you prevent bad actors from beating the original artist to the punch, and registering someone else's artwork as theirs on the blockchain?
For example, on a platform like Soundcloud there are many Rhiannas but it is obvious which account the "real" Rihanna is because she has the most followers, likes, etc. Popularity can be another data point.
Projects like Blockstack already offer solutions that take a similar approach, allowing you to link your social media accounts so your identity is more trustable.
We also envision developers and trusted organizations like Creative Commons or DPLA creating indexes on top of Mediachain to help users filter the data.
Okay dispute happens Alice has Reputation X and Bob has Reputation Y. So first who or what does Alice dispute to and second so what: if X > Y, Alice becomes the owner?
