What is the consensus mechanism used by XPLA?

Could you elaborate on the consensus mechanism utilized by XPLA? I'm particularly interested in understanding how it ensures the security and stability of the network. Does it employ a traditional proof-of-work model, or has it adopted a more energy-efficient approach such as proof-of-stake? Additionally, what are the key advantages of this consensus mechanism over other alternatives in the cryptocurrency landscape? Any insights you can provide would be greatly appreciated.
