Multi-layer architecture refers to a design model where different layers work together to enhance functionality, scalability, and security. In this setup, each layer serves a specific purpose and can operate independently while contributing to the overall system.The base layer, often called Layer 1, forms the core of the blockchain framework. It handles essential tasks such as transaction processing, consensus mechanisms, and security. Layer 1 is typically slower and less flexible, which can limit scalability.To address these limitations, Layer 2 solutions are developed on top of Layer 1. These solutions enable faster transactions and greater throughput by processing operations off the main chain. Layer 2 can include technologies like payment channels or sidechains, allowing for increased efficiency and lower fees.By separating concerns between these layers, multi-layer architecture promotes innovation and allows for more complex functionalities without overloading the base layer. This separation facilitates seamless interaction while maintaining the security and integrity of the underlying blockchain.
