What is Decentralized Finance (DeFi)?
Decentralized Finance (DeFi) is a blockchain-based financial system that operates without intermediaries like banks, brokers, or exchanges. Instead, it relies on smart contracts (e.g., Ethereum) to facilitate financial activities. DeFi platforms enable users to:
- Lend/borrow funds
- Trade cryptocurrencies
- Earn interest via savings-like accounts
As of August 2021, over $150 billion was locked in DeFi protocols.
Key Features of DeFi
| Feature | DeFi | CeFi (Traditional Finance) |

| Accessibility | Permissionless, open to all | Requires KYC/registration |
| Transparency | Fully auditable on-chain | Limited visibility |
