Protocol Skill - The Digital Passport (VAI & DID)
| name | description |
|---|---|
| protocol | Manages the PAI's Verified Agent Identity (VAI) and Decentralized Identifiers (DIDs). USE WHEN you need to authenticate with other PAIs or services using cryptographic proof of authorization. |
The Key Insight
Trust is the currency of 2030. Protocol ensures your PAI is recognized as a legitimate extension of your sovereign identity. It uses DIDs and JWTs to prove "Proof of User Intent" before any data exchange occurs.
Usage
Generate Passport
bash
pai run Protocol generate
Prove Identity
bash
pai run Protocol prove "session_token"
How it Works
It implements the W3C DID standard. It signs challenges with your local hardware-secured keys (managed by Citadel) to produce verifiable credentials that other agents can trust without a central authority.
Strategic Value
- •Anti-Bot Defense: Shields your interactions from non-human-authorized "slop-bots."
- •Verifiable Agency: Allows your PAI to speak for you with the same legal weight as a digital signature.
- •Interoperability: Works across all 2026+ agent communication standards (MCP, A2A).
