According to ChainCatcher, CoinDesk reported that Christie's will provide blockchain-based digital ownership certificates for each lot at the "Focus on Reality: Photos from the Collection of Ambassador Trevor Trainor" auction held at Rockefeller Center in New York.

It is reported that the auction involves 130 works, and the ownership certificates will be minted by Kresus on the Ethereum second-layer blockchain Base developed by Coinbase. Christie's got involved in blockchain technology as early as 2021, when it auctioned Beeple's "Everyday" series for $69 million.
