The Internet has revolutionized the way we access, communicate, store and share knowledge, but it has been much less successful in providing security and privacy.  The capacity that governments, private companies, and skilled individuals have to hack our world is almost unlimited. We all know that when we fire off information into cyberspace, it is, for all intents and purposes, public. But change is on the horizon. New technology known as Blockchain facilitates transactions without intermediaries. Keeping the user's information anonymous, Blockchain both validates and keeps a permanent public record of all transactions. This development promises to revolutionize financial transactions on the web, make banks irrelevant, and restore trust in digital communications. In the this episode, host Janice Stein speaks with author Don Tapscott about his book, Blockchain Revolution: How the Technology behind Bitcoin is Changing Money, Business, and the World. Tapscott, writing with his son Alex, argues that Blockchain technology will shape the next era of prosperity - in finance, business, healthcare, education, governance and beyond.
