Since October last year, digital artist Cory Van Lew tweeted that a major auction house has been in arrears on auction payments for his artwork and has hired a lawyer to resolve the issue. That's why blockchain is so valuable to artists, Cory Van Lew said, enabling him to build his auction platform without the constraints of traditional sales methods. Another artist, Drift, noted that the auction house might be Sotheby's, and Sotheby's has also defaulted on its auction payment, but the tweet posted by Drift has been deleted.
