"Blockchain is a foundational technology whose impacts could reach into every corner of the world."  This week, Engage covers the hottest fintech story impacting market structure and governance.  Why is mutual mistrust a key element for creating trust with this new technology?  We bring on Wharton Prof. Kevin Werbach to discuss his new book, "The Blockchain and the New Architecture of Trust."  Going beyond Bitcoin, Ethereum and cryptos, we dive into how blockchain is being developed in Walmart's food supply chain, we talk about permissioned blockchains and we hit on why government plays a critical role.
