By now you've probably heard of Bitcoin. But Bitcoin isn't the only digital currency. In fact, there are hundreds of "altcoins" out there, all of which are different from Bitcoin in varying degrees. One of the hottest new currencies is ZCash, a digital currency designed to provide more anonymity than Bitcoin. And unlike Bitcoin, whose founder is pseudonymous and unknown to the public, ZCash was backed by a company with a known team. In the latest episode of Odd Lots, ZCash founder Zooko Wilcox explains how and why he launched his own currency and explains why anyone would actually use it.
