Which network is Hedera on?

Could you please elaborate on the network Hedera operates on? I'm curious to understand its underlying infrastructure and technology. Is it based on a blockchain platform? Or perhaps it utilizes a different type of distributed ledger technology? Additionally, how does Hedera's network architecture contribute to its scalability, security, and performance? I'm interested in knowing more about its unique features and advantages compared to other networks in the cryptocurrency and finance space.
