If you go on youtube there is a popular youtube channel (i got sucked into because its a personal interest of mine but i digress) that does a show called VFX artists explain and on there they had this guy who made the most money ever selling one of his NFT pieces of art, didnt even have to early life this guy, everyone in the comment section of the video saying the exact same thing, 'oh look, its a jew using NFT to launder money through art, story as old as time'. His name is Beeple and even the autistic california liberals on the channel were like "wow who is this ultrta successful artist dressed in a business suit but swearing ever 3rd word like a 12 year old sailor" that would be zie juden mein nigger I saw other VFX channels agonizing over how much money this kike made. Wondering what it was that made them less deserving. My dude you are a goyim. You arent a worse aritst than this Beeple kike youre just not jewish enough to be picked for dumb nigger pocket change time

Basically it's the equivalent of a signed meme. It's called a nonfungible token and there is some way that it is permanently marked to prove that it's the original meme or something to that effect.
