DeFi Explained Simply: Lending, Yield Farming, and Liquidity
Decentralized finance, or DeFi, represents a set of financial applications running on blockchain without traditional intermediaries like banks. Unlike conventional finance, these protocols are accessible to everyone, 24/7, and are governed by smart contracts. Three core concepts structure this ecosystem: lending, yield farming, and liquidity. Here’s a simple breakdown. 1. Decentralized Lending: In DeFi, lending or borrowing crypto assets happens without credit checks or bank paperwork. How it works: Lenders deposit their crypto into a protocol (like Aave or Compound). Borrowers can withdraw these assets by providing collateral, typically exceeding the loan amount (often 150%). If the collateral’s value drops too much, it’s automatically liquidated to repay the loan. Key points: Lenders earn interest on their deposits. Borrowers pay that interest but retain exposure to their assets (e.g., borrowing stablecoins without selling their ETH). The main risk is liquidation if the market crashes. 2. Yield Farming: Yield farming involves placing crypto into DeFi protocols to generate income, often in the form of additional tokens. How it works: You provide liquidity to a protocol (e.g., depositing a token pair into a pool). In return, you receive liquidity tokens representing your share. The protocol rewards you with transaction fees and sometimes governance tokens. Key points: Returns can be very high, but they are often volatile and depend on protocol activity. Farming exposes
