Bitcoin is one of the most talked about but least understood technological innovations of recent years, continuing to draw new backers on Wall Street and Silicon Valley. New York Times reporter Nathaniel Popper's book, Digital Gold, illuminates this confounding technology through the first ever narrative recounting of Bitcoin's dramatic rise to prominence, which benefited from access to all the major players. He will be joined on stage by the programmer who has been leading the Bitcoin project since 2010, Gavin Andresen, and one of the biggest venture capitalists to back the technology, Fred Wilson of Union Square Ventures.
