So this should be a marketplace platform where you will sell art? What types of art are you going to sell? Thyis will be like auction or just like online shop?
I think this is more like an online store in which any master can sell his works of art.
I learned in WP that it is more than an online store. An important component will be the authentication of paintings through the blockchain, and I think that cooperation with galleries will be able to expand the capabilities of the platform.
