VeritasChain Protocol (VCP) now offers a cryptographic audit trail for TradingView strategies. The new vcp-tradingview-rta-reference implementation lets Pine Script users generate tamper-evident logs. This solves the 'black box' problem where algorithmic trading decisions lack verifiable proof, a growing concern for prop trading firms and regulatory compliance.

Traditional logs are editable and forgeable. VCP's three-layer architecture uses SHA-256 hashing, Ed25519 signatures, and Merkle trees for integrity. A Python sidecar handles canonical JSON and external anchoring. This creates an immutable record of every trade event, preventing modification or deletion of critical data.

The system uses a sidecar pattern since TradingView runs sandboxed. Pine Script captures events, sends them via webhook, and the sidecar signs and organizes them. This provides regulatory compliance for MiFID II and the EU AI Act, plus dispute resolution between traders and brokers.

This open standard is in its Silver Tier, targeting retail traders. Future plans include MT4/MT5 bridges and institutional FIX support. The project is moving toward IETF standardization, aiming to make cryptographic audit trails a baseline requirement for algorithmic trading accountability.
