What network is Chia on?

Excuse me, I'm curious about the underlying infrastructure of the Chia cryptocurrency. Could you elaborate on what network Chia is built upon? I've heard about blockchain technology and various consensus algorithms, but I'm not entirely sure which one Chia employs. Is it a Proof-of-Work (PoW) or Proof-of-Stake (PoS) model? Furthermore, does Chia utilize any novel network protocols or architectures that set it apart from other cryptocurrencies? I'd appreciate a concise yet thorough explanation of Chia's network design and its advantages. Thank you.
