The initial integration cost of an identity authentication system is very low, but once it becomes the foundation of the entire process, it becomes extremely difficult to dismantle and rebuild.

idOS_network happens to be in such a position. On-chain business involves user onboarding, permission management, compliance checks, and data flow—identity authentication is intertwined, gradually evolving into the "load-bearing wall" of the entire ecosystem. Once it takes on this role, a small change can cause a chain reaction; any replacement or removal will trigger a series of consequences.

This is also why the choice of Web3 infrastructure is crucial. Although it may seem simple and straightforward at the beginning, the migration costs in later stages can be enough to cause the entire project to stumble.
