Blockchain technology is about to transform every trust-based interaction of our lives, from financial services to identity, from health care to our Internet of Things devices. In this podcast, host Laura Shin talks with industry pioneers across tech, financial services, health care, government and other sectors about how the blockchain and cryptocurrency will open up new opportunities for incumbents, startups and everyday people to interact more efficiently, directly and globally.

Daniel Lehnberg and Michael Cordner, core team members of Grin, discuss the first implementation of the MimbleWimble protocol, named after a tongue-tying curse in Harry Potter. We discuss the many ways in which Grin is similar to Bitcoin: its origin story, its goal to be "digital cash," as Satoshi's paper was subtitled, and even its emission schedule. We discuss how Grin is private, how it is lighter weight than the Bitcoin blockchain, and the philosophy behind Grin, which stands in stark contrast to the many ICOs.
