CryptoKitties Slow Down Blockchain

Available for over a year

A game involving buying and breeding digital kittens gives blockchain technology a friendly face, but exposes weaknesses with the Ethereum cryptocurrency in meeting demand. We talk to Elsa Wilk from Axiom Zen, the company behind the game. Plus, we hear how the city of Moscow is applying blockchain tech to a citizen voting system. Andrey Belozerov, Moscow's strategy and innovations adviser, tells us more. And, Cindy Sui reports on how Taiwan plans to grow a software startup scene. Presented by Rory Cellan-Jones, with BBC tech reporter Jane Wakefield, and special guest Kate Bevan, tech journalist and information security specialist.
