What chain is Roost on?

Excuse me, could you clarify for me which blockchain network is Roost currently operating on? I'm curious to know if it's leveraging the security and decentralization of a major blockchain platform like Ethereum, Binance Smart Chain, or perhaps a lesser-known network with unique features that cater to Roost's specific needs. It would be great if you could provide some insight into the choice behind the selected blockchain, and how it benefits Roost and its users.
