A verifiable digital credential (often a Decentralized Identifier or DID) that uniquely identifies an AI agent and its authority level.
Agents are increasingly treated as Non-Human Identities (NHIs). Cryptographic identity ensures that when Agent A talks to Agent B, the identity is verifiable via public-key cryptography (e.g., Ed25519 signing). This prevents Agent Spoofing and creates an immutable audit trail for every action taken across a multi-agent reasoning chain.
Real world example:
A finance agent signs its Transfer Request with its Cryptographic Identity; the receiving bank's governance kernel verifies the signature before processing the transaction, ensuring the request came from a sanctioned bot.
