Substrate Layering Solutions refers to a design framework that allows for the construction of blockchains with customizable features. At its core, Substrate enables developers to create tailored blockchain solutions built on pre-existing components, making the process more efficient.The architecture is modular, meaning developers can select different layers for consensus mechanisms, networking, and runtime logic. This modularity allows for easy upgrades and adjustments without overhauling the entire system.In addition, Substrate supports interoperability, enabling different blockchains built on it to communicate and interact. This capability is key for developers looking to build complex decentralized applications that require collaboration between various blockchain ecosystems.Overall, Substrate Layering Solutions provide a flexible and efficient way to build, customize, and connect blockchains, catering to a wide range of use cases and developer preferences.
