Let me start first by checking whether this site
is a trusted source of information?
Then it’s written there
So what prevent the auctioneer from resell it again?
( make a new token pointing to the same file?)
- He used the example of a receipt, if a marchant signed 2 receipts for the same item u could press charges against him, what about NFT?
-I mean other than tampering or making a slight change, does the “create” or “transfer” functions check if the hash already exists, ie have been minted before? or they just verify it?
(A marchant could sign & seal 2 manual receipts to be only discovered in court, but a computerized system wouldn’t print a 2nd receipt from the beginning)
In one sentence
How does NFTs prevent double spending?or they just don’t?
