The base layer, often referred to as the foundation, is the first and most crucial component of a multi-layered system. In various contexts, such as clothing, software, or blockchain technology, the base layer provides essential support and stability. It serves as the groundwork upon which additional layers or functionalities are built, ensuring that the entire system operates effectively. In the context of clothing, the base layer typically consists of moisture-wicking materials that keep the skin dry and comfortable. In blockchain technology, the base layer refers to the underlying protocol that facilitates transactions and data storage, while higher layers can introduce additional features or applications.
