As an example, let's say I have original Mona Lisa in my possession. I create some fancy digital NFT picture out of the original one and put it for sale on OpenSea. Whoever buys my NFT gets that original Mona Lisa picture with this NFT delivered to their home address.
Let's say Buyer A makes a purchase, NFT is transferred to him automatically and I will send original Mona Lisa by post to Buyers A home address.
So far so good, everything is straight forward.
Let's say Buyer A wants to resell that NFT and Buyer B buys it. How to ensure that Buyer A will send original Mona Lisa to Buyer B? There is too much space for scam from here on as Buyer A can easily disappear after that without sending original Mona Lisa to Buyer B.
What would be the best approach for reselling those kind of NFTs? How to keep track where original items are and if they are sent out from sellers or received by buyers?
