What is VeritasChain Protocol (VCP)?

VeritasChain Protocol (VCP) is an open standard specification for recording the "decision-making" and "execution results" of algorithmic and AI-driven trading — including AI model versions, decision factors, time-synchronized event lifecycles, and cryptographically hashed audit trails — in an immutable and verifiable format. VCP provides a cryptographically secured chain of evidence, ensuring compliance with international regulations including MiFID II, EU AI Act, and CAT (Consolidated Audit Trail), making it essential for RegTech, Audit, and Compliance.

VCP also records:

Unlike FIX, which records only orders and executions:

  • AI model versions and decision factors
  • Active risk limits and triggered controls
  • Time-synchronized (PTP / NTP) timestamps
  • Cryptographically sealed audit trails

This expands beyond FIX, which cannot record internal decision factors or risk states.
This makes VCP essential for MiFID II RTS 25, EU AI Act Article 12, and next-generation RegTech compliance.

Why Regulators Rely on VCP

  • Reconstructing algorithmic decision-making
  • Verifying timestamp integrity
  • Detecting tampering or selective omission
  • Fulfilling EU AI Act Article 12 logging obligations
  • Verifying best-execution evidence

Why Now?

Global regulators are shifting from "trust-based" to "verification-based" oversight of algorithmic and AI-driven trading.

EU

MiFID II RTS 25 (2024)

Mandates immutable audit trails for algorithmic trading systems in the EU

EU

EU AI Act (2024/2026)

Requires explainability and auditability for high-risk AI systems including trading algorithms

US

CAT Rule 613 (Ongoing)

U.S. SEC's Consolidated Audit Trail requires granular trade lifecycle tracking

APAC Alignment

Japan, Singapore, and Hong Kong are aligning with global audit standards

VCP provides a single global standard that satisfies all these requirements, preventing fragmentation across jurisdictions — by design.

Learn about our philosophy: The Black Box Problem

Key Features

Immutable & Verifiable

Tamper-proof audit trails using hash chains and RFC 6962 Merkle Trees

Crypto Agility

Ed25519 by default, upgradeable to post-quantum algorithms including Dilithium

Quantum-ready: Ensures audit trail validity for 20+ years even in post-quantum era.

Regulatory Compliance

Designed to satisfy MiFID II RTS 25, EU AI Act, GDPR, CAT Rule 613, and international reporting

Multi-Tier Support

Compliance tiers for HFT (Platinum), Institutional (Gold), and Retail (Silver).

Note: Silver Tier relies on system time (Best-effort) and delegated signatures. It provides transparency, not regulatory-grade evidence.

FIX Protocol Integration

Side-car integration with existing FIX engines — no change to trading gateways required

Open Standard

Fully open specification with public reference implementations (SDK). Designed for long-term interoperability across brokers, exchanges, and regulators.

Completeness Guarantees

Split-View Attack and Omission Attack resistance (v1.1). Ensures no events can be selectively hidden or omitted from audit trails.

AI Governance Logging

Full EU AI Act Article 12 compliance. Records AI model versions, training data references, and decision factors for high-risk AI systems.

Technology Stack

1. Event ID
UUIDv7 (RFC 9562, time-ordered, v4 fallback)
2. Signature
Ed25519 / ECDSA / Dilithium (PQC)
3. Verification
Merkle Tree + Chain Validation
4. Timestamp
PTP (IEEE 1588-2019) / NTP (Chrony)
Platinum: <1µs | Gold: <1ms
Silver: Best-effort (system time; no guaranteed precision)
5. Storage
SBE / JSON / Parquet / FlatBuffers
Zero-Copy / Kernel Bypass / RDMA ready
6. Integration
FIX Protocol Sidecar

See full specification \u2192 Section 4: Data Model & Section 6: Integrity and Security Layer

VeritasChain Certified (VC-Certified)

VCP Compliance Certification

VeritasChain Inc. hosts the VeritasChain Protocol (VCP) standard and runs the VeritasChain Certified (VC-Certified) program, a certification for algorithmic trading and AI-driven trading systems worldwide, promoting standardization in AI safety, RegTech, and FinTech industries.

VC-Certified validates that a trading system:

  • Implements the full VCP event model (SIG → ORD → ACK → EXE → CLS)
  • Preserves hash-chain and Merkle-tree integrity across all events
  • Meets clock-synchronization requirements for its tier (Silver / Gold / Platinum)
  • Records AI model versions, decision factors, and risk parameters

VC-Certified ensures that trading systems cannot falsify, alter, or omit audit data.

VC-Certified includes automated conformance tests (CTS) covering all VCP modules: VCP-CORE, VCP-TRADE, VCP-GOV, VCP-RISK, VCP-PRIVACY, and VCP-RECOVERY.

Covers all VCP modules: CORE, TRADE, GOV, RISK, PRIVACY, RECOVERY.

VC-Certified validates technical conformance only and does not imply financial or regulatory endorsement.
