Behind Jeff Koons and David Hockney, the most lucrative auction for a piece of art from a living artist happened in 2021—and it was for a work that existed in a JPEG file. The artist Beeple's "Everydays—The First 5,000 Days," a series of digital artworks, sold at Christie's for the princely sum of $69.3 million.
It was a stunning event made possible by a technology called non-fungible tokens (NFTs).
