The Problem

AI agents are increasingly making purchase decisions on behalf of consumers. The agentic commerce stack is taking shape -- but there is a critical missing layer:

┌──────────────────────────────────────────────────────────────────┐ │ AI Agent Commerce Protocol Stack │ ├──────────────────────────────────────────────────────────────────┤ │ │ │ Visa TAP ·············· Agent Identity Verification │ │ Google UCP ············ Structured Data Exchange │ │ Stripe ACP ············ Payment Processing │ │ │ │ ┌───────────────────────────────────────────────────────────┐ │ │ │ OTR Protocol ····· MERCHANT TRUST VERIFICATION ◀━━━━━ │ │ │ │ "Is this merchant safe to buy from?" │ │ │ └───────────────────────────────────────────────────────────┘ │ │ │ │ Visa TAP answers "Who is the AI agent?" │ │ Google UCP answers "What products are available?" │ │ Stripe ACP answers "How do I pay?" │ │ OTR answers "Should I trust this merchant?" ◀━━ ONLY OTR │ │ │ └──────────────────────────────────────────────────────────────────┘

Without OTR, AI agents operate blind -- unable to distinguish a legitimate retailer from a sophisticated scam site. This exposes consumers to fraud and erodes trust in the entire agentic commerce ecosystem.

The Solution

OTR (Open Trust Registry) provides deterministic, verifiable merchant trust scores using 6 verification dimensions, a 10-layer anti-fraud pipeline (Layer 0: Google Web Risk one-vote veto + Layers 1-9: core detection engine), and three-layer immutable audit trail. It is fully open-source (MIT), machine-readable, and designed from the ground up for AI agent consumption.

Key Properties

Deterministic -- Same inputs always produce identical outputs. Any validator can reproduce any score.

Verifiable -- All data sources are publicly accessible. No hidden factors or proprietary signals.

Unforgeable -- Verification dimension weighted at 40% in public assessment. SEC filings, Wikidata entries, and 10-year domain age cannot be faked.

Tamper-proof -- SHA-25
