This paper presents a research-oriented cryptographic design and formal security analysis;
it is not a finalized protocol specification.

📜 Internet-Draft (IETF – in preparation)

An Internet-Draft is in preparation to propose VCP as a SCITT-aligned auditability profile for algorithmic trading systems.

Status: Draft in progress (not yet submitted to IETF Datatracker)

  • Working title: SCITT Profile for Verifiable Trading Audit Trails
  • Target WG: IETF SCITT (Security Area)

📌 Canonical Specification

The canonical (normative) specification of VeritasChain Protocol (VCP) is maintained in the following repository and directory structure:

vcp-spec/
 └─ spec/
    ├─ v1.1/   (current)
    └─ v1.0/   (legacy)

All other formats (HTML, PDF, translations) are non-normative.

AI Decision Auditability Benchmark (v1.0)

A vendor-neutral benchmark for evaluating the auditability and evidence quality of AI and algorithmic decision systems.

  • Designed for audit, assurance, and compliance teams
  • 10 criteria / 20-point evaluation scale
  • Minimal assessment executable in ~3 hours
  • Aligned with EU AI Act (Articles 12, 13, 14, 17) and MiFID II / RTS requirements

Canonical reference (released v1.0):

📖 What is VCP?

VeritasChain Protocol (VCP) is the world's first open standard for creating immutable, cryptographically verifiable audit trails in algorithmic and AI-driven trading systems.

The Problem

In 2024-2025, the proprietary trading industry faced a crisis:

  • $450M+ in trader payouts frozen
  • 80-100 prop firms collapsed or suspended operations
  • Zero standardized way to verify trading records

The Solution

VCP provides a universal audit format that enables:

Capability Description
Hash Chain SHA-256 linked events create tamper-evident audit trails
Digital Signatures Ed25519 signatures prove event authenticity
Merkle Proofs RFC 6962-compliant proofs for external verification
Regulatory Alignment EU AI Act, MiFID II, SEC/FINRA, FCA ready

⚡ Quick Start (5 Minutes)

Python

pip install veritaschain
from veritaschain import VcpLogger, create_event
import os

# Initialize
logger = VcpLogger(
    endpoint="https://api.veritaschain.org/v1",
    api_key=os.environ["VCP_API_KEY"]
)

# Log a trading signal
event = create_event("SIG", {
    "venue_id": "MT5_DEMO",
    "symbol": "EURUSD",
    "account_id": "demo_account",
    "vcp_gov": {
        "algo_id": "my-strategy-v1",
        "confidence_score": "0.85"
    }
})

logger.log(event)
logger.flush()
print(f"✅ Logged: {event.header.event_id}")

TypeScript

npm install @veritaschain/sdk
import { createLogger, createEvent } from '@veritaschain/sdk';

const logger = createLogger({
  endpoint: 'https://api.veritaschain.org/v1',
  apiKey: process.env.VCP_API_KEY!
});

const event = createEvent('ORD', {
  venueId: 'EXCHANGE_01',
  symbol: 'BTCUSD',
  accountId: 'trader_123',
  vcpTrade: {
    orderId: 'ord_001',
    side: 'BUY',
    price: '42150.50',
    quantity: '0.5'
  }
});

await logger.log(event);
console.log(`✅ Logged: ${event.header.eventId}`);
