# Verified Agent Identity

> Give your AI agent a cryptographic identity with a verified human owner on the Billions Network.

## What is agent identity?

Every AI agent today runs without a real identity — just code executing somewhere, with no way to prove who owns it or is accountable for what it does.

## Verified Agent Identity

The **Verified Agent Identity** skill solves that: it gives any AI agent a decentralized identifier (DID) on the Billions Network and links it permanently and verifiably, on-chain, to a real human owner.

Once linked, the agent can prove it is operated by a real, unique human. Service providers get spam protection, and anyone can look up a public, tamper-proof record of who stands behind the agent — sybil resistance without asking the agent to give up its autonomy.
