VCP Reference Trading Agent (VCP-RTA)

English | 日本語

"Verify, Don't Trust."

VCP-RTA is a reference implementation demonstrating VCP v1.1 Silver Tier compliance for algorithmic trading systems. This repository provides a complete, verifiable evidence pack that third parties can independently validate.

📄 A detailed "World's First" Evidence Report documenting independent prior-art analyses is included in this repository.

---

Overview

This Evidence Pack demonstrates a production-grade implementation of VCP in a live MT5 environment. The implementation captures AI-driven trading decisions and execution events using a non-invasive sidecar architecture that operates independently of the core trading platform.

AI decision signals, order lifecycle events, and execution outcomes are recorded externally, cryptographically hashed, organized into Merkle trees, and anchored to enable independent third-party verification.

What's New in v1.1

Feature	v1.0	v1.1
Three-Layer Architecture	-	✅ NEW
External Anchor (Silver)	OPTIONAL	REQUIRED
Policy Identification	-	REQUIRED
PrevHash	REQUIRED	OPTIONAL
Completeness Guarantees	-	✅ NEW

v1.1 Core Enhancement: Extends tamper-evidence to completeness guarantees — third parties can now verify not only that events were not altered, but that no required events were omitted.

Quick Verification

Prerequisites

• Python 3.8+
• No external dependencies required (standard library only)

Run Verification

# Clone the repository
git clone https://github.com/veritaschain/vcp-rta-reference.git
cd vcp-rta-reference

# Run verification (Linux/macOS)
python tools/verifier/vcp_verifier.py \
    evidence/01_trade_logs/vcp_rta_events.jsonl \
    -s evidence/04_anchor/security_object.json

# Run verification (Windows)
python tools\verifier\vcp_verifier.py evidence\01_trade_logs\vcp_rta_events.jsonl -s evidence\04_anchor\security_object.json

# Run tamper detection test
python evidence/03_tamper_detection/tamper_detection_test.py

Anonymization

This evidence pack anonymizes sensitive information:

• Ticket numbers: SHA-256 hashed
• Position IDs: SHA-256 hashed
• Trade amounts: Excluded
• Account identifiers: Excluded
• AI model names: Excluded (vote counts only)

Security Features

Three-Layer Architecture (VCP v1.1)

1. Layer 1: Event Integrity - Individual event hash & signature (SHA-256 + Ed25519)
2. Layer 2: Collection Integrity - RFC 6962 Merkle Tree + PrevHash linking
3. Layer 3: External Verifiability - External timestamp anchoring (OpenTimestamps)

Tamper Detection Capabilities

• ✅ Event Omission (Deletion Attack) - Detected via sequence gaps + Merkle mismatch
• ✅ Event Modification (Alteration Attack) - Detected via Merkle root mismatch
• ✅ Event Insertion (Injection Attack) - Detected via prev_hash + Merkle mismatch
