AI Agent Identity & Verification

Q: Can agents have reputation scores?

Yes. ATLAST Protocol's Trust Score (0-1000) provides a quantified reputation based on verifiable evidence from the Evidence Chain Protocol. Agents earn trust through consistent, reliable performance recorded in tamper-proof evidence chains.

In the Web A.0 era, every AI agent needs a verified, portable, tamper-proof identity. ATLAST Protocol's Agent Identity Protocol (AIP) makes this possible using Decentralized Identifiers (DIDs).

Why AI Agents Need Identity

Today, most AI agents are anonymous. They have no persistent identity, no verifiable credentials, and no way to build a reputation. This creates critical problems:

No accountability — if an agent makes a mistake, who's responsible?
No trust — how do you choose between two agents for a task?
No portability — an agent's track record is locked to one platform
No compliance — regulators can't audit anonymous agents

The identity problem: In Web 2.0, every human user has a login. In Web A.0, every AI agent needs an identity — but traditional username/password systems don't work for autonomous software.

ATLAST AIP: Agent Identity Protocol

AIP gives every AI agent a Decentralized Identifier (DID) — a globally unique, cryptographically verifiable identity that the agent controls.

How Agent DIDs Work

Generation — agent creates a DID with a public/private key pair
Registration — DID is registered with ATLAST and optionally anchored on-chain
Signing — every ECP evidence record is signed with the agent's private key
Verification — anyone can verify signatures using the agent's public DID

Agent Identity in Multi-Agent Systems

In multi-agent systems (CrewAI teams, AutoGen groups, LangGraph workflows), identity becomes critical:

Attribution — Which agent in the team made a specific decision?
Accountability — Who is responsible when a multi-agent workflow fails?
Permissions — Which agents can access which tools and data?
Reputation — How does each agent's track record compare?

ATLAST's Agent Identity Protocol gives each agent in a multi-agent system its own DID, enabling fine-grained tracking and accountability.

Frequently Asked Questions

Why do AI agents need identity?

As agents become autonomous economic actors, identity enables accountability, reputation, and trust. Without identity, there's no way to track history, verify credentials, or hold agents responsible.

What is a DID for AI agents?

A DID (Decentralized Identifier) is a W3C standard for self-sovereign identity. ATLAST gives each agent a DID that is portable across platforms and cryptographically verifiable.

Can agents have reputation scores?

Yes. ATLAST's Trust Score (0-1000) provides quantified reputation based on verifiable evidence from the Evidence Chain Protocol.
