What is L0 in crypto?
Could you please elaborate on the concept of L0 in the world of cryptocurrency? As a novice in this field, I'm curious to understand the foundational layer that L0 represents and how it relates to the broader cryptocurrency ecosystem. Is it a specific technology, a standard, or something else entirely? How does it impact the security, scalability, and overall functionality of blockchain networks? And, how does it compare to other layers within the cryptocurrency stack?
