PTVS Core Specification v1.0

The Sovereign Standard for Real-World Asset Verification & Legal Binding

1. Introduction & The Physical Oracle Gap

Current blockchain architectures provide mathematical certainty for digital state transitions but remain fundamentally blind to physical reality. This disconnect, termed the Physical Oracle Gap, represents the primary systemic risk in RWA tokenization. A smart contract cannot independently verify if a tokenized building has structural decay, if a yacht has been double-pledged, or if a supply chain asset has been compromised.

PTVS resolves this gap by introducing a sovereign layer of verification that combines judicial forensic expertise, qualified electronic signatures (eIDAS 2.0 QES), and immutable cryptographic anchoring, creating a standard that is legally admissible in over 125 jurisdictions.

2. Scope & Purpose

This specification defines the requirements for:

• The generation and validation of Qualified Forensic Evidence Records (QFER).
• The cryptographic anchoring of physical verification data to the LO-PR Immutable Registry.
• The integration of legal mandates (e.g., court orders) into smart contract execution logic.
• The creation of “Hollow Tokens” in the event of cryptographic compromise or legal seizure.

3. Terms & Definitions

• QFER (Qualified Forensic Evidence Record): A cryptographically signed, legally admissible document verifying the physical and legal state of an asset, signed by a certified PTCE using eIDAS 2.0 QES.
• PTCE (Prop Trust Certified Expert): A judicially certified expert authorized to conduct in-situ inspections and issue QFERs under the PTVS methodology.
• LO-PR (Layer-0 Physical Registry): The immutable, decentralized registry where QFER hashes and legal mandates are anchored.
• Hollow Token: A digital token that has been cryptographically decoupled from its underlying physical asset due to a legal freeze or verification revocation, rendering it valueless and non-executable.

4. Core Architecture: The Three-Layer Model

4.1. Layer 0: Physical Verification (The Reality Layer)

All verification begins in the physical world. A PTCE conducts an in-situ inspection following the PTVS methodology. The findings are documented, signed with a Qualified Electronic Signature (QES), and hashed (SHA-256).

4.2. Layer 1: Cryptographic & Legal Binding (The Trust Layer)

The QFER hash is submitted to the LO-PR Immutable Registry. This registry acts as the single source of truth for the asset’s physical state. Any interaction with the asset’s digital representation requires a valid, non-expired entry in this registry.

4.3. Layer 2: On-Chain Integration (The Execution Layer)

Smart contracts governing the RWA must implement specific modifiers and functions to enforce the binding between the digital token and the physical reality verified in Layers 0 and 1.

5. Smart Contract Primitives

To achieve sovereign compliance, RWA smart contracts MUST implement the following primitives:

5.1. The `isPhysicallyAndLegallyBound` Modifier

This modifier acts as a mandatory gatekeeper for any state-changing function (minting, transferring, redeeming). It ensures that the asset has a valid, current QFER anchored in the LO-PR.

// PTVS Core Specification: Mandatory Modifier
modifier isPhysicallyAndLegallyBound(bytes32 _assetId) {
    // 1. Verify existence of a valid QFER in the LO-PR
    require(LOPRRegistry.getLatestQFERHash(_assetId) != bytes32(0), 
        "PTVS: Asset lacks physical verification");
    
    // 2. Verify the QFER has not expired or been revoked
    require(LOPRRegistry.isVerificationCurrent(_assetId, MAX_DAYS_OLD), 
        "PTVS: Physical verification expired or revoked");
    
    // 3. Verify the QFER is signed by an active, certified PTCE
    require(PTCERegistry.isActiveSigner(LOPRRegistry.getQFERSigner(_assetId)), 
        "PTVS: Invalid or inactive PTCE signature");
    _;
}

5.2. The `freezeByLegalMandate` Function

In the event of a security breach, theft, or legal order, this function allows a designated Compliance Role to deterministically freeze the asset, creating a “Hollow Token” for the compromised address.

// PTVS Core Specification: Legal Enforcement Function
event AssetFrozenByLegalMandate(bytes32 indexed assetId, address indexed frozenAccount, bytes32 legalOrderHash);

function freezeByLegalMandate(bytes32 _assetId, address _targetAccount, bytes32 _courtOrderHash) external onlyLegalComplianceRole {
    require(_targetAccount != address(0), "PTVS: Invalid address");
    
    // Mark the asset as frozen for this specific account
    frozenAssets[_assetId][_targetAccount] = true;
    
    // Anchor the legal order hash in the LO-PR for immutable auditability
    LOPRRegistry.recordLegalFreeze(_assetId, _targetAccount, _courtOrderHash);
    
    emit AssetFrozenByLegalMandate(_assetId, _targetAccount, _courtOrderHash);
}

modifier notFrozen(bytes32 _assetId) {
    require(!frozenAssets[_assetId][msg.sender], "PTVS: Asset frozen by legal mandate");
    _;
}

6. Conformity & The “PTVS Verified” Seal

An asset is only considered “PTVS Verified” if it successfully passes the Conformity Assessment defined in this specification. The right to use the “PTVS Verified” seal is exclusively licensed by Aurema Group LLC and is subject to continuous compliance with the LO-PR registry status.
