Blockchain layering refers to the organization of blockchain architecture into different levels to enhance scalability, efficiency, and functionality. Each layer serves a specific purpose, allowing for modular development and easier upgrades.The base layer, often called Layer 1, includes the core blockchain protocols and ensures security and consensus. This layer is responsible for recording transactions and maintaining the integrity of the network.Layer 2 solutions are built on top of Layer 1 to facilitate faster transactions and lower fees. They handle a significant volume of transactions off the main chain while periodically syncing with it. Popular examples include payment channels and sidechains.Additional layers may be used for enhancing specific functionalities such as smart contract execution or privacy features. By compartmentalizing various functions across layers, developers can create a more flexible and user-friendly system. This approach allows networks to adapt to changing demands without disrupting the foundational blockchain, paving the way for innovation and improved user experiences.
