What network is ZEC on?

Could you please elaborate on the network that ZEC, or Zcash, operates on? I'm particularly interested in understanding the underlying technology and infrastructure that supports this cryptocurrency. Is it a blockchain-based system? If so, what are some of the key characteristics and advantages of this network? How does it differ from other popular networks in the cryptocurrency space? I'd appreciate a concise yet informative description that helps me grasp the technical underpinnings of ZEC's network.
