What network is Flare on?

Could you please clarify for me which network Flare operates on? I'm interested in understanding the technological infrastructure that supports its operations. Is it based on a traditional blockchain, or perhaps a newer, more innovative platform? Additionally, I'm curious about the network's scalability, security measures, and integration with other cryptocurrency systems. Could you provide some insights into these aspects? I'm eager to learn more about Flare's network and how it fits into the broader cryptocurrency ecosystem.
