Which crypto is layer 0?
Excuse me, could you please clarify what you mean by "layer 0" in the context of cryptocurrency? I'm not familiar with that particular terminology as it's not a widely used or standardized label in the crypto industry. Are you perhaps referring to a specific blockchain protocol or network architecture that operates at a foundational level? If so, could you provide some more context or examples to help me better understand your question? It's important to note that there isn't a universally agreed-upon definition of "layer 0" in the crypto space, so any explanation would greatly appreciate your input.
