Ann: AB1 Invests in Dapper Labs, the company behind CryptoKitties, page-34

"Once in a while, we have hackathons - we call it Dappathon. We invite hundreds of hackers over, open up a few rooms in a co-working space, order pizzas, stock Red Bulls, and build dapps to solve day-to-day problems. But this time was different. Last weekend, we had the chance to partner with TechCrunch China along with other fellow partners CryptoKitties and Animoca Brands and host a hackathon in Shenzhen.

The challenge was “Develop an Ethereum based decentralized application (dapp) utilizing the CryptoKitties API” - a unique kitty-flavored challenge. It integrated blockchain technology and gaming. Everyone was able to experience and get value from the digital assets, and crypto collectibles.

The teams had only 24 hours to finish their dapps, and prepare for their PowerPoint presentation for the judges, mentors, and the inquisitive audience. During the 24 hours period, all we did was create, share ideas, and think of our favorite furry friend - CryptoKitties."
