I understood the description correctly - the secondary market of paintings will be open to those participants who bought the painting through the ArtPro platform?
In theory, it should be so. But later we will be announced here. Fully detailed how it will happen with art.
I think it's easier to start selling the secondary market with the first buyers of Art Pro. All of them will have confirmation of transactions through the blockchain. And during this period, the preparation of the platform section for authentication for other sellers who are not artists will continue.
