Whose-was-first NFTs
Is it possible on any existing blockchain to create a non-fungible token that meets these requirements?


 * No matter how many times the NFT has changed hands, a user who knows the current owner and has access to a trusted node that has observed all b blocks and stores O(log b) data, where b is the blockchain height, can determine the creator's address and the block in which it was minted within O(1) time.
 * No two creators can create NFTs with identical content in the same block.
 * The NFT never changes hands without the transaction being signed by the current owner.
