# ERC-8004

> Maestro's Bitcoin agent registered on-chain via ERC-8004 for trustless discovery, reputation tracking, and verification by any AI agent.

# ERC-8004

[ERC-8004](https://www.8004scan.io/agents/ethereum/22763) ("Trustless Agents") is an Ethereum standard that defines a blockchain-based protocol for **agent discovery and trust establishment** across organizational boundaries. It enables AI agents to discover, evaluate, and interact with other agents without pre-existing trust relationships — creating the foundation for open agent economies.

While existing standards like MCP and A2A handle agent communication, ERC-8004 adds the missing layer: **discovery and trust**.

## How It Works

ERC-8004 defines three on-chain registries:

| Registry       | Purpose                                                                                                                                                                      |
| :------------- | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Identity**   | ERC-721-based registry assigning each agent a globally unique identifier and an `agentURI` pointing to its registration file. Agents are browsable and transferable as NFTs. |
| **Reputation** | Collects feedback signals from clients. Core data stored on-chain, detailed feedback off-chain. Supports filtering, revocation, and response appending.                      |
| **Validation** | Enables independent verification of agent work. Validators respond with outcomes on a 0–100 scale.                                                                           |
