System architecture emphasizes "robustness," that is, the ability to survive under abnormal conditions. The dual-layer security model of XAI (Arbitrum consensus + Sentinel challenge) ensures that the network remains resilient even under large-scale attacks. This enterprise-level stability is a prerequisite for attracting traditional Web2 gaming giants (such as Ubisoft, SE, etc.) to enter the space. They dare not launch games on chains that can go down at any time, but they dare to launch on XAI.
