DeFi Protocols

Definition ∞ DeFi protocols are decentralized applications that provide financial services without traditional intermediaries. These protocols operate on blockchains, enabling functions like lending, borrowing, trading, and yield generation through smart contracts. They represent a significant shift towards open and accessible financial systems.
Context ∞ The current discourse surrounding DeFi protocols often centers on their rapid innovation, potential for disintermediation, and associated risks. Key debates involve the security of smart contracts, the regulatory treatment of decentralized financial instruments, and the challenges of user protection in a permissionless environment. Future developments are anticipated to focus on enhancing protocol security, improving user experience, and clarifying regulatory compliance pathways.
