Multi-Layer Architecture

Definition ∞ Multi-Layer Architecture organizes a system into distinct, interacting layers, each with specific functions. This design principle separates concerns into logical tiers, such as presentation, application, and data layers, to enhance modularity, scalability, and maintainability. Each layer communicates with adjacent layers through defined interfaces, allowing for independent development and upgrades. In blockchain, this often involves a base layer for security and settlement, with upper layers for scaling and applications.
Context ∞ The discourse on Multi-Layer Architecture frequently concerns the trade-offs between system complexity and performance gains in decentralized networks. A key debate involves optimizing communication and data transfer efficiency between different layers. Observing advancements in layer-2 scaling solutions and modular blockchain frameworks offers valuable insight.
