Blockchain is a technology behind cryptocurrency Bitcoin, but does it have other uses? Jessi Baker is founder of tech startup Provenance, and explains how the firm uses blockchain as a way of verifying the supply chain of companies selling products such as food and fashion. Avivah Litan of technology research company Gartner tells us where blockchain currently stands in its conception of the HypeCycle, which it uses to describe the life cycle of many new technologies. And we get wider context from Richard Johnson, financial technology expert at Greenwich Associates in New York. Also in the programme, Apple has removed a mapping app from its app store in response to concern from China that it was being used by protesters in Hong Kong to target and ambush police officers.
