What network is Sui on?

Could you possibly elaborate on the network Sui is operating on? I'm rather curious to know more about the technological backbone that supports this cryptocurrency. Is it built on a widely-used blockchain, or does it have its own unique platform? Could you also explain the advantages and disadvantages of the chosen network? Understanding these details would greatly assist me in grasping the intricacies of Sui and its position in the cryptocurrency landscape. Thank you in advance for your clarification.
