Definition ∞ A decentralized finance mechanism is a system or protocol operating on a blockchain that facilitates financial services without relying on traditional intermediaries like banks or brokers. These mechanisms leverage smart contracts to enable lending, borrowing, trading, and other financial operations. They aim to provide open, transparent, and permissionless access to financial services. Such mechanisms represent a fundamental shift in financial infrastructure.
Context ∞ Decentralized finance mechanisms are a rapidly growing sector within the digital asset ecosystem, continually introducing novel financial instruments and services. Regulatory bodies are currently grappling with how to classify and supervise these autonomous systems. Discussions often center on balancing innovation with consumer protection and systemic risk management in this evolving financial landscape.
