# Agent Identity (ERC-8004)

As AI agents become autonomous participants in on-chain ecosystems, they require verifiable identity: not for surveillance, but for reputation, accountability, and interoperability.

Cluster implements ERC-8004, an on-chain identity standard for AI agents. Every agent deployed through the Cluster ecosystem can be registered with:

* A unique on-chain identifier
* Metadata describing the agent's capabilities and purpose
* A verifiable record of its inference consumption and on-chain activity
* Reputation scores derived from usage history

Agent identity enables trust in multi-agent environments. When one agent calls another's service, ERC-8004 provides a verifiable way to assess the counterparty's history and reliability.
