What network is Paal on?

Excuse me, I was just wondering, could you please clarify which network does Paal operate on? I understand that there are various blockchains and networks in the cryptocurrency space, and it's important to know the specifics when it comes to investing or using a particular cryptocurrency. Is Paal built on a popular network like Ethereum or Bitcoin, or is it on a lesser-known one? It would be great if you could provide some more details on this matter. Thank you in advance for your help.
