Ucii Overview

UCII Overview

Universal Cryptographic Identity Infrastructure

UCII is cryptographic identity infrastructure designed for humans, AI agents, devices, services, robots, and organizations.

The core design principle:

> Identity is the primitive. Authentication is an application.

UCII separates permanent cryptographic identity from authentication methods, credentials, and authorization systems.

    Economic Authorization

    Protected infrastructure operations use x402.

    The flow:

    1. Client requests an operation.

    2. UCII returns payment requirements.

    3. Client submits payment authorization.

    4. Settlement is verified.

    5. Operation executes.
