Is star network in blockchain?

Could you please clarify what you mean by "star network" in the context of blockchain? Are you referring to a specific network topology or architecture that utilizes blockchain technology? If so, it's important to note that blockchain technology is typically associated with decentralized networks that utilize a peer-to-peer (P2P) architecture, where nodes communicate directly with each other without relying on a central authority. However, it's possible that some blockchain projects or networks may have adopted a "star" topology for certain purposes, such as to improve scalability or reduce latency. Can you provide more context or specific examples to help me better understand your question?
