From the perspective of systems engineering, the upper limit of any system depends on its weakest link. The blockchain trilemma (decentralization, security, scalability) has always been a curse. XAI breaks this curse through modular design: leveraging Arbitrum to inherit Ethereum's security, using Sentry Nodes to ensure decentralization, and employing Orbit technology to achieve unlimited scalability. This is a "hexagonal warrior" architecture with no obvious shortcomings. For AAA-level blockchain games that need to support millions of users, the available infrastructure options on the market are actually quite limited, and XAI is undoubtedly the most mature in terms of technology stack and the most comprehensive in ecological support.
