The purpose of DeFi is to move traditional financial businesses to the blockchain network, achieve decentralization, and reduce intermediate costs. By replacing traditional centralized financial institutions with smart contract functionality, DeFi allows users to enjoy financial services at a lower cost and improve the efficiency of the financial system.
