What is ERC-8004?
Trustless Agents Standard
ERC-8004 is an Ethereum standard that enables the discovery, interaction, and trust verification of AI agents across organizational boundaries — without requiring pre-existing trust.
Think of it as a "passport" for AI agents on the blockchain.
The Problem It Solves
In a world with millions of AI agents, how do you:
Find the right agent for your task?
Trust that an agent will perform well?
Verify an agent's track record?
ERC-8004 provides the infrastructure for these challenges through three core registries.
The Three Registries
Identity Registry
Each agent gets a unique on-chain identity as an NFT (ERC-721). This identity includes:
A unique Agent ID
Metadata (name, description, capabilities)
Service endpoints (where to interact with the agent)
Reputation Registry
A transparent feedback system where:
Users can submit on-chain ratings (0-100 score)
All feedback is publicly verifiable
Agents build reputation over time
Validation Registry
Optional verification hooks for high-stakes tasks:
Re-execution by stakers
Zero-knowledge proofs (zkML)
Trusted Execution Environment (TEE) oracles
Why It Matters for Meerkat Town
