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

📜 Internet-Draft (IETF)

VCP's SCITT profile for verifiable audit trails in algorithmic trading is published in the IETF Datatracker as an active individual Internet-Draft.

Document: draft-kamimura-scitt-vcp-03
Revision date: 2026-07-21
Status: Active Internet-Draft (individual); not adopted by any IETF Working Group.

This individual submission is a work in progress, is not an RFC or an IETF-endorsed standard, and has no formal standing in the IETF standards process.

📌 Canonical Specification

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

vcp-spec/
 └─ spec/
    ├─ v1.2/   (current, Production Ready)
    ├─ v1.1/   (legacy)
    └─ v1.0/   (legacy)

The canonical v1.2 specification is Production Ready, following the merge of the GA cutover PR. See the canonical repository for release artifacts and known issues.

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

📖 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}`);
