What is the root network?

Could you elaborate on the concept of "root network" in the context of cryptocurrency and finance? I'm interested in understanding its fundamental principles and how it differs from traditional financial networks. Specifically, I'd like to know if it serves as a decentralized infrastructure, enabling secure transactions and enabling novel financial applications. Additionally, I'm curious about its scalability, security measures, and potential impact on the future of finance. Could you provide a concise yet comprehensive explanation of the root network?
