Canada's Axiom Zen proudly presents CryptoKitties, one of the first games to leverage #blockchain technology. Interesting move as the gaming industry is both very active and represents serious amounts of potential revenue.
Among many challenges, the stress it will put on the network itself will have to be addressed as CryptoKitties clogged the network and made up to 11% of all transactions on ethereum.
But with the recent craze of digital cats being sold for up to $117,712 , one can only dream of the potential market.. I, for one, foresee an interesting mashup between CryptoKitties smart contracts mechanism and PokemonGo's viral success... A new land of opportunities for daring entrepreneurs.
