What network is Z on?

Could you please clarify which network you are referring to when you mention "Z"? There are numerous blockchains and cryptocurrency networks out there, each with their unique characteristics and use cases. Without specific details about "Z," it's difficult to give a definitive answer. Is "Z" a specific cryptocurrency, a decentralized application, or perhaps a reference to a certain blockchain technology? If you could provide more context or specific information about "Z," I would be happy to offer a more precise response regarding the network it belongs to.
