Decentralized Finance (DeFi) is a financial system built on blockchain networks that removes the need for traditional intermediaries like banks or brokers.
It uses smart contracts—self-executing code—to facilitate transactions such as lending, borrowing, and trading directly between users.
Because it operates on open-source protocols, DeFi is permissionless and global, allowing anyone with an internet connection to access financial services.
Transactions are recorded on a public ledger, ensuring transparency and reducing the risk of centralized manipulation or censorship.
By automating complex processes, DeFi aims to create a more efficient, inclusive, and cost-effective alternative to the legacy financial world.
