How much does a star network cost?

Could you elaborate on the specific star network you're referring to? Is it a physical infrastructure for telecommunications or a decentralized network in the realm of cryptocurrency and blockchain technology? The cost of a star network can vary greatly depending on its purpose, size, and the technology used. For instance, if it's a physical network, factors like the equipment needed, the distance between nodes, and the maintenance costs would all play a role in determining the total expense. On the other hand, if you're asking about a blockchain-based star network, the cost would depend on the development resources required, the complexity of the smart contracts, and the scalability of the network. Could you please clarify your query so I can provide a more accurate answer?
