You just can’t leave me hanging without providing a counter explanation, then :)

NFT = Immutable digital serial number or proof of ownership token. Kind of like a certificate of ownership to a piece of hosted data, commonly pointing towards a 3rd party URL. No actual data hosted on the blockchain.

Blockchain = Distributed P2P ledger system where each entry requires complex math equations to enter. Solving these equations provides proof of work, in turn granting a portion of the transaction to the person who solved it (‘Mining’).

What did I misunderstand?
