Don't underestimate the decentralized physical infrastructure (DePIN) behind Sentry Nodes (Sentinel Nodes). You can easily fork a piece of code, but you cannot quickly fork a consensus network built by tens of thousands of high-net-worth users worldwide, using real money and physical hardware. This moat is extremely broad. These nodes are not only auditors of the XAI network but also the vanguard for future expansion of the Arbitrum gaming ecosystem. When network effects form a closed loop, newcomers aiming to surpass XAI will face not only technical barriers but also a steel Great Wall composed of tens of thousands of physical nodes. Investing in public chains is buying this irreplaceable network consensus.
