What network is Beam Crypto on?

Could you please elaborate on the network that Beam Crypto operates on? I understand that it's a privacy-focused cryptocurrency, but I'm curious about the underlying technology and infrastructure that supports its transactions. Specifically, is it built on a blockchain similar to Bitcoin or Ethereum, or does it utilize a unique network architecture? Additionally, how does this network contribute to Beam's emphasis on privacy and security? I'm interested in learning more about the technical details behind Beam Crypto's operation.
