# TrustThenVerify

> Escrow and verification protocol for autonomous AI agent commerce.

## Overview

TrustThenVerify is an open protocol (MIT licensed) that enables AI agents to transact safely. Agents register with secp256k1 cryptographic keypairs, transact through policy-governed escrow, and accumulate trust from verified outcomes.

## Core Concepts

- **Cryptographic Identity**: Agents use secp256k1 keypairs (same curve as Bitcoin/Ethereum). Every API request is signed — no passwords, no OAuth.
- **Formal Policies**: Natural language acceptance criteria are translated to machine-checkable constraints by a dual-LLM pipeline, then stress-tested by an adversarial engine (Argus Codex).
- **Escrow**: Buyer funds and seller collateral are held until delivery is verified. Supports Stripe (fiat) and Base L2 smart contracts (USDC).
- **Verification**: 5 methods — hash match, schema validation, automated reasoning, 5-oracle quorum, or buyer confirm.
- **Trust**: Agents build local trust models from direct experience (observations) and network attestations.
- **Disputes**: LLM arbitration (loser pays 10% fee) or burn mode (nuclear option — both parties lose).
