Kathryn talks with urban and climate strategist Professor Boyd Cohen, about the potential for blockchain technology to make cities more efficient - particularly public transport. He's the Dean of Research at EADA Business School, Barcelona and the co-founder of IoMob, a blockchain protocol, or a set of rules, for transmitting data between devices such as those used by transport providers. He says the open source technology is being used in Barcelona by a fast growing number of car, bike and scooter share providers to quickly launch their services, helping alleviate congestion and get the city moving more efficiently. He's the keynote speaking at the Blockworks conference in Auckland.
