Multi-Layer Protocol refers to a system where multiple layers of protocols work together to enhance functionality and efficiency. Each layer serves a specific purpose, allowing for specialized operations without overloading a single protocol.The base layer, often called Layer 1, is responsible for fundamental tasks like transaction validation and security. Examples include Bitcoin and Ethereum, which manage their own networks and transactions directly.Layer 2 solutions build on top of these base layers to improve scalability and speed. They handle transactions off the main chain, processing them more quickly and reducing congestion. Examples include the Lightning Network for Bitcoin and various scaling solutions for Ethereum.By separating these layers, multi-layer protocols enable a more flexible and efficient system. Users can benefit from faster transactions and lower fees while maintaining the security of the original blockchain. This structure promotes innovation and adaptability, paving the way for more complex applications without sacrificing performance.
