Decentralized finance (DeFi) is revolutionizing financial services by leveraging blockchain technology to create an open, permissionless ecosystem. This guide explores the fundamentals of DeFi, its key applications, and how beginners can safely navigate this space.
What Is DeFi?
DeFi refers to a suite of financial applications built on blockchain networks that enable peer-to-peer transactions without intermediaries like banks. Key characteristics include:
- Decentralization: Operates on public blockchains (e.g., Ethereum).
- Transparency: All transactions are recorded on immutable ledgers.
- Accessibility: Open to anyone with an internet connection and a crypto wallet.
Core Benefits of DeFi
- Inclusivity: Eliminates traditional barriers like credit checks.
- Efficiency: Reduces costs and delays associated with intermediaries.
- Innovation: Supports novel financial products (e.g., smart contract-based loans).
