A blockchain game CryptoKitties, launched in November 2017. The game made headlines in December 2017 when a cryptokitty character - an in-game virtual pet - was sold for more than US$100,000. CryptoKitties illustrated scalability problems for games on Ethereum when it created significant congestion on the Ethereum network with about 30% of all Ethereum transactions being for the game.
CryptoKitties also demonstrated how blockchains can be used to catalog game assets (digital assets).
