The main purpose is remarkable and very useful, but there's the issue of the initial information that must be provided from another source. How do you think to handle with that? Thanks!
If you are talking about the authenticity of the paintings, then it is too early to talk about it. Everything is solved very simply: the work must be sold either by the artist or he must give power of attorney to sell his works.
Sorry, but in my opinion is the main thing: if the 1st information is wrong that all the immutable chain lose its purpose. It's not for criticism, but I think that, if you want to operate also for already existent items and not just with new ones, you should consider a bit more this thing.
