Bitcoin has been around for about ten years. But the dream of a decentralized, anonymous digital currency has been around for decades. On this week's podcast, we speak with one of the original godfathers of the space, David Chaum, an American cryptographer, who first wrote about digital cash in the early 80s. Chaum's original vision wasn't exactly the same as what we know as cryptocurrencies today, but many of the ideas were the same, and Chaum's work was cited by many of the early crypto believers. On this week's podcast, we talk to him about the history of his work, cryptocurrency, and where he sees it going now.
