Welcome back to another episode of our limited addition Crypto Series on the Rational Reminder Podcast, a weekly reality check about sensible investing and financial decision-making. Are cryptocurrencies and the associated technologies beneficial? Could they change the world for the better? There is a lot of controversy surrounding the use and application of cryptocurrencies and the associated technologies. Some say the innovation is ultimately useless while others think it is the answer to society’s problems. To help us unpack this complicated and hot-button topic is Bruce Schneier, an internationally-renowned security technologist, author, and educator. The focus of his work is the intersection of security, technology and people. Bruce also has an immense passion for educating people about cryptocurrencies. Examples of his well-known books include Liars and Outliers and Data and Goliath, which provide much-needed insight to readers about DeFi technologies and big monopolies. He also lectures in public policy at the Harvard Kennedy School and is a fellow at the Berkman Klein Center for Internet and Society. In our conversation, we discuss the debate surrounding cryptocurrencies such as privacy concerns of digital cash, what makes Bitcoin different from earlier digital currencies, aspects of public blockchain technology, the misapplications of crypto technology, the different forms and approaches to cryptocurrencies, and whether DeFi technologies can be beneficial to society, and what the biggest concerns are regarding cryptocurrencies. Join us today as we take a detailed look into the value and drawbacks of crypto and DeFi technology with Bruce Schneier!
