Russian artist Petr Davydtchenko made what what he claims was the first performance art NFT in February. According to an article in The Art Newspaper, in a digital recording, Davydtchenko "eats a live bat in front of the European Parliament in Brussels."

An NFT, or non-fungible token, is a digital record of the stake in ownership of a digital object (but not the copyright), often an artwork. This digital certificate says, "I paid for this special thing, now it's mine!"
