Modular Abstraction

Definition ∞ Modular abstraction is a design principle that breaks down a complex system into independent, self-contained components with well-defined interfaces. Each module handles a specific function, allowing for greater flexibility, easier maintenance, and independent upgrades. This approach separates concerns, making systems more adaptable and manageable.
Context ∞ In blockchain architecture, modular abstraction is increasingly applied to protocol design, enabling different layers or functionalities to be developed and upgraded independently. News frequently covers “modular blockchains” that separate execution, data availability, and consensus layers, promising enhanced scalability and customization. This design philosophy is central to the ongoing evolution of decentralized networks.
