# AgentLedger: Trust Infrastructure for the Agent Web

> AgentLedger is trust infrastructure for AI agents — manifest registry, blockchain-anchored trust ledger, and tamper-proof audit chain for autonomous commerce.

AgentLedger is the missing trust infrastructure for autonomous AI agents. Over 104,000 AI agents are now registered across 15+ incompatible registries — yet no standard exists for an agent to verify whether a service is safe to call. AgentLedger fills that gap with three integrated components: a universal Manifest Registry for service discovery, a blockchain-anchored Trust Ledger for immutable attestation, and an Audit Chain for liability-grade action logs.

## The Three Components

AgentLedger addresses the trust and discovery gaps in today's agent protocol stack through three integrated components:

<Steps>
  <Step title="Manifest Registry">
    Services publish a structured manifest at `/.well-known/agent-manifest.json` declaring their capabilities, pricing, data requirements, and SLAs. Agents query the registry by capability ontology tag, natural language, or ambient discovery to find verified services before interacting with them.
  </Step>

  <Step title="Trust Ledger">
    Attestation events, revocation records, and version history are anchored on-chain — making trust claims independently verifiable by any agent without relying on AgentLedger directly. No single party, including AgentLedger, can retroactively alter a service's trust history.
  </Step>

  <Step title="Audit Chain">
    Every consequential agent action — bookings, payments, record access — is captured in a PII-stripped, cryptographically linked audit record. This enables dispute resolution, liability attribution, and EU AI Act compliance without exposing sensitive user context.
  </Step>
</Steps>
