🧒 5살도 이해할 수 있게 설명
Imagine a soda machine that also gives out loans. You don't need to talk to a banker or show your ID; you just put in your [collateral](/ko/terms/collateral), and the machine gives you the money automatically because the rules are written right into the machine's code. [DeFi](/ko/terms/defi) is a giant network of these 'money machines' that never sleep and belong to everyone.
🤓 Expert Deep Dive
Technically, DeFi relies on 'Composability'—the ability for different apps to interact with each other like 'Money Legos'. For example, you can take a 'Flash Loan' from one protocol, trade it on a 'DEX' (Decentralized Exchange) like Uniswap, and deposit the profit in a 'Yield Aggregator'—all in a single transaction. A critical component is the 'Automated [Market Maker](/ko/terms/automated-market-maker)' (AMM), which replaces order books with '[Liquidity Pools](/ko/terms/liquidity-pools)' and mathematical pricing curves (x*y=k). However, users must be aware of 'Impermanent Loss', which occurs when the price of tokens in a pool changes significantly, and 'Smart Contract Risks', where a bug in the code can lead to a total loss of funds with no recourse.
