What is DeFi?
DeFi (Decentralized Finance) is a blockchain-based financial system that operates without centralized intermediaries like banks or governments. It leverages cryptocurrencies and DApps (Decentralized Applications) to facilitate peer-to-peer transactions, offering greater transparency and user control.
Key Features of DeFi:
- Permissionless Access: Anyone can participate without approval.
- Transparency: All transactions are recorded on public ledgers (blockchains).
- Smart Contracts: Self-executing agreements eliminate third-party reliance.
What is a DeFi Coin?
DeFi coins are digital assets used within decentralized ecosystems. They can:
- Be pegged to fiat currencies (e.g., stablecoins like DAI).
- Fluctuate based on market demand (e.g., governance tokens like UNI).
- Enable lending, borrowing, or trading via DApps.
What Are DApps?
DApps are blockchain-based applications that run on decentralized networks. Examples include:
- Decentralized Exchanges (DEXs): Like Uniswap for trading crypto.
- Lending Platforms: Like Aave for earning interest on deposits.
Why DeFi Matters in Crypto
- User Sovereignty: Control your assets via private keys in digital wallets (e.g., MetaMask).
- Global Transactions: Send/receive funds worldwide without bank delays.
- Inflation Hedge: Some view crypto as a store of value amid economic instability.
