Decentralized Finance (DeFi) is a revolutionary movement in finance that leverages blockchain technology to create a more open and accessible financial system. It aims to remove intermediaries like banks and financial institutions from traditional financial transactions. Instead, DeFi utilizes smart contracts, which are self-executing agreements written in code, to enable peer-to-peer lending, borrowing, trading, and other financial services. This allows for greater transparency, reduced costs, and increased accessibility for users. DeFi applications are typically built on public blockchains like Ethereum, where anyone can participate and access financial services regardless of their location or background.
