The Ethereum world has been purring over the cutest use of the blockchain yet: CryptoKitties! The community has spent the past week buying, selling, and breeding a nearly infinite variety of cartoon cats. Fur is flying over the heavy strain the application has put on the Ethereum network and the increased fees that have come with it. Rare cats have sold for incredible amounts — the very first CryptoKitty, Genesis, sold for 250 ether (approximately $115,000 at the time).
The frenzy has left a key question unanswered: who really owns your CryptoKitties?
