十年集成之痛，一个 集线器 之解A Decade of Integration Pain, One Hub Solution

做过企业数字化的人都知道，系统集成最麻烦的不是接口协议，而是 "用户映射" ——
同一个用户在系统A是 user_001，在系统B是 emp_234，在系统C是 customer_789，谁都不知道他们是同一个人。
如今，AI Agent 的爆发让"机器身份"和"自主代理"成为刚需，DID Hub 要做的不仅是连接人，更是连接 人与机器、机器与机器 之间的信任。Anyone who's done enterprise integration knows the hardest part isn't protocols — it's "user mapping".
The same user is user_001 in System A, emp_234 in System B, customer_789 in System C — nobody knows they're the same person.
Today, the rise of AI Agents makes "machine identity" and "autonomous agents" essential — DID Hub is not just about connecting people, but about building trust between humans and machines, and between machines.

DID Hub 就是为此而生——它是一座 身份集线器，
严格遵循 W3C 国际标准，用去中心化身份（DID）替代传统用户ID，
让所有系统用同一个身份语言对话，从此告别映射之痛，拥抱 AI Agent 时代。 DID Hub was built for this — it's an identity hub,
strictly following W3C standards, replacing traditional user IDs with decentralized identity (DID),
letting all systems speak the same identity language — goodbye mapping pain, embrace the AI Agent era.
