In DeFi and the Future of Finance, Campbell R. Harvey, Ashwin Ramachandran, and Joey Santoro, introduce the new world of Decentralized Finance. The book argues that the current financial landscape is ripe for disruption and we are seeing, in real time, the reinvention of finance. The authors provide the reader with a clear assessment of the problems with the current financial system and how DeFi solves many of these problems. The essence of DeFi is that we interact directly with our peers - there are no intermediaries or associated costs. Savings and lending are reinvented. Trading takes place with automated algorithms far removed from traditional brokerages.
