Description: “DeFi,” or decentralized finance, is an emerging financial system built on blockchains without central intermediaries such as banks. Defi has experienced explosive growth in the last couple of years, with billions of capital locked in numerous DeFi protocols on blockchains.

Understanding this makes it possible to predict potential future crashes and develop behavioral interventions for subsequent market recoveries.
