When I began to teach in 2012, I decided to start my course with an analysis of how money affects social order. What my students found particularly fascinating was the then-nascent world of cryptocurrencies, which I described at length as a crucial feature in the future of money.
Some colleagues criticized my approach. They accused me of indirectly encouraging students to invest in what they saw as a shady, crime-ridden financial underworld. But I was simply exposing young minds to a fast-evolving, complex phenomenon that in my view would have a major impact on power distribution in the global economy.
Behind most cryptocurrencies is a simple technology known as “blockchain”, a system residing in multiple computers that allows for peer-to-peer financial ledger recording of all transactions occurring in a network.
