A new technology often elicits both hopes and fears for the future, and Bitcoin is no exception. Current controversies surrounding Bitcoin mainly stem from the conception of the technology simply as a new virtual ‘currency’. Tony Young-Suc Lyu, CEO of Korea’s first Bitcoin exchange Korbit, tells us we need to understand its less obvious underlying technology called the ‘blockchain’ to grasp a fuller picture of the enormous potential it offers. For the first time in human history, the blockchain is making available a globally shared ledger. And the technology is about more than money – it can be a paradigm-shifting platform with implications much broader than we can imagine. Tony shares with us the fundamentals of Bitcoin that have many prominent Silicon Valley venture capitalists and entrepreneurs enthralled.
