Decentralized Finance

Definition ∞ Decentralized finance, often abbreviated as DeFi, is a system of financial services built on blockchain technology that operates without central intermediaries. DeFi applications aim to replicate traditional financial services like lending, borrowing, and trading in a permissionless and transparent manner. This approach democratizes access to financial tools and reduces reliance on established financial institutions.
Context ∞ The current discourse around DeFi frequently involves discussions on its scalability limitations, user experience challenges, and the evolving regulatory landscape. While DeFi continues to introduce innovative financial products, concerns persist regarding the security of smart contracts and the potential for systemic risks within interconnected protocols. Future developments will likely focus on enhancing security, improving interoperability, and achieving greater regulatory accommodation.
