Decentralized Finance — or DeFi — has experienced explosive growth in the past year. But in order for DeFi to fulfill its promise as a disintermediated ecosystem that helps rather than harms, “now is the time to evaluate its benefits and dangers,” write Wharton legal studies and business ethics professor Kevin Werbach and David Gogel, a recent Wharton MBA graduate, in the article that follows. Werbach is author of the book The Blockchain and the New Architecture of Trust and leads Wharton’s Blockchain and Digital Asset Project. Werbach and Gogel recently collaborated with the World Economic Forum to create the Decentralized Finance (DeFi) Policy-Maker Toolkit, providing guidance to regulators and blockchain watchers everywhere.
The market experienced explosive growth beginning in 2020. According to tracking service DeFi Pulse, the value of digital assets locked into DeFi services grew from less than $1 billion in 2019 to over $15 billion at the end of 2020, and over $80 billion in May 2021. Novel business models such as yield farming — in which holders of cryptocurrencies earn rewards for providing capital to various services — and aggregation to optimize trading across exchanges in real-time are springing up rapidly. Innovations such as flash loans, which are either repaid or automatically unwound during the course of a transaction, open up both new forms of liquidity and unfamiliar risks.
