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.
The main thing is that all attempts at manipulation in this aspect are determined and no one can deceive the platform. Then the credibility of the project will grow.
