Definition ∞ Compositional methods in blockchain refer to ways different protocols or smart contracts can be combined to create new functionalities. This concept permits the layering of distinct decentralized applications or financial primitives, where the output of one system serves as the input for another. It allows for the creation of complex financial products and services by reusing and integrating existing, verified components. This modular approach significantly accelerates innovation and reduces development time within the decentralized finance ecosystem.
Context ∞ The extensibility offered by compositional methods is a key driver of innovation in DeFi, enabling the rapid creation of new financial instruments and liquidity strategies. News frequently discusses how protocols leverage these methods to build sophisticated applications, highlighting the synergistic effects and potential for emergent system properties in the digital asset landscape.
