Receipt

Receipt is a conceptual art using NFT. The visual is determined by the amount you pay. You can pay any amount; you can mint (create) one token per price. All the code to draw is stored on the blockchain. The transaction itself is your participation in the art.
The reality of the value of NFT is the exchange of data on the blockchain, which is used by many people who trust it. 0xhaiku believes that the memory of the act itself is the new value of art.
