* **Key Features:**
    * **Trustless:** Eliminates intermediaries like banks and brokers.
    * **Permissionless:** Accessible to anyone with an internet connection.
    * **Decentralized:** Operates on a distributed network, not controlled by any single entity.
* **Key Components:**
    * **Lending/Borrowing:** Peer-to-peer lending platforms like Aave and Compound.
    * **Decentralized Exchanges (DEXs):** Platforms like Uniswap for trading crypto assets without intermediaries.
    * **Stablecoins:** Cryptocurrencies pegged to stable assets like the US dollar.
    * **Yield Farming:** Earning rewards by providing liquidity to DeFi protocols.
