In 2008, during the turbulence of a global financial crisis, a person (or group) called Satoshi Nakamoto released a white-paper called Bitcoin: A Peer-to-Peer Electronic Cash System. The principle was simple but revolutionary- a technique to record digital transactions in a way that was public, permanent and verifiable without requiring a third party for trust. It is this principle that became more commonly known as Blockchain (or distributed ledger). Today, just 13 years later, the cryptocurrency market is valued at a staggering $1.6 trillion (around 2% of the entire global economy) and blockchain based companies are raising some of the largest rounds of funding in technology. To understand more about Blockchain and Cryptocurrencies I spoke to Nobel Prize Winning Economist, Professor Eric Maskin and a global expert on blockchain and cryptocurrency, Michel Rauchs.
