Is immutable a layer 1?

Is immutable a layer 1?" This question seems to be querying the classification of a certain technological or architectural concept within the realm of blockchain and cryptocurrency. Layer 1, in the context of blockchain technology, typically refers to the main blockchain protocol itself, the fundamental layer that underlies all transactions and smart contracts. It is the core infrastructure, setting the rules and standards for the entire network. The term "immutable" generally refers to something that cannot be changed or altered. In the blockchain world, this often applies to transactions and data recorded on the chain, which are designed to be permanent and unalterable. This is a key aspect of blockchain's security and trustworthiness. However, to answer the question "Is immutable a layer 1?" directly, it is not entirely accurate to categorize "immutable" as a layer 1. Instead, immutability is a characteristic or principle inherent in many blockchain protocols, particularly those designed for secure and transparent transactions. Layer 1 refers more to the specific blockchain protocol or network itself, rather than a single aspect or feature of that protocol. Therefore, while immutability is a crucial aspect of many layer 1 blockchains, it is not itself a layer 1. It is rather a fundamental property that contributes to the security and reliability of these blockchain networks.
