Modular Stack

Definition ∞ A modular stack refers to a software or protocol architecture composed of distinct, independent layers or components that can be developed, upgraded, and operated separately. In blockchain technology, this approach allows for specialization, where different layers handle specific functions like data availability, execution, or settlement. This design promotes flexibility, scalability, and innovation by enabling individual components to be optimized without affecting the entire system. It simplifies maintenance and allows for diverse implementations.
Context ∞ The concept of a modular stack is central to discussions about the future architecture of blockchain networks, particularly in the context of scaling solutions and Layer 2 protocols. News often covers projects building modular blockchains, where different components can be swapped or customized to suit specific application needs. This architectural shift is seen as a key driver for improving efficiency, reducing costs, and expanding the capabilities of decentralized ecosystems.
