Modular Blockchain

Definition ∞ A modular blockchain is a distributed ledger architecture that separates core functions, such as execution, settlement, and consensus, into distinct layers. Each layer can be independently developed, upgraded, or replaced. This design allows for greater flexibility and specialization within the blockchain ecosystem. It aims to address limitations found in monolithic blockchain designs.
Context ∞ The concept of modular blockchains is gaining significant traction as a potential solution for enhancing scalability and flexibility. Current discussions focus on various architectural approaches, including rollups and specialized data availability layers. Debates often center on the optimal division of labor between these modules and the security implications of inter-module communication. Future developments are expected to see the proliferation of interoperable modular components, allowing for highly customizable and performant blockchain networks.
