Prop Trust Verified Standard
The definitive technical specification for deterministic off-chain forensic auditing and cryptographic verification of Real World Assets in blockchain tokenization.
What is PTVS v1.0?
The Prop Trust Verified Standard (PTVS) is a comprehensive framework that bridges the critical gap between physical asset reality and blockchain immutability. It provides a deterministic, legally binding methodology for verifying the structural integrity, legal status, and physical condition of Real World Assets before tokenization.
Unlike traditional oracles that rely on centralized data feeds, PTVS leverages certified judicial expertise, cryptographic anchoring, and smart contract integration to create an immutable chain of custody from physical inspection to on-chain verification.
The standard is designed to eliminate "toxic RWAs"—tokens collateralized by assets with hidden pathologies, legal encumbrances, or structural defects—by mandating forensic-level verification as a prerequisite for token minting.
Key Features
Judicial Authority
Audits performed by certified judicial experts with legal accountability and professional liability insurance
Cryptographic Proof
SHA-256 hashing with RFC 3161 timestamps ensuring immutable evidence of asset condition at time of audit
On-Chain Integration
Native compatibility with ERC-3643 and ONCHAINID protocols for automated compliance verification
Academic Validation
Peer-reviewed methodology indexed in CERN/Zenodo, SSRN/Elsevier, and HAL Open Science archives

ERC-3643 & ONCHAINID Compatibility
PTVS v1.0 is designed to seamlessly integrate with the ERC-3643 tokenization standard and ONCHAINID identity management system. The standard injects cryptographically signed forensic claims directly into the token's compliance module.
When a token issuer implements PTVS, the smart contract automatically verifies the presence and validity of the forensic audit claim before allowing minting, transfers, or trading. This creates an automated compliance gate that ensures only assets meeting forensic verification standards can be tokenized.
The integration uses standard Solidity interfaces and requires minimal code changes to existing ERC-3643 implementations, making adoption straightforward for tokenization platforms.
// PTVS Claim Structure for ERC-3643
struct PTVSClaim {
bytes32 claimType;
bytes32 evidenceHash;
uint256 timestamp;
address auditor;
bytes signature;
string metadataURI;
}
// Integration Example
function verifyPTVSClaim(
address token,
PTVSClaim memory claim
) public view returns (bool) {
require(
claim.claimType == PTVS_PHYSICAL_VERIFICATION,
"Invalid claim type"
);
require(
isCertifiedAuditor(claim.auditor),
"Auditor not certified"
);
return verifySignature(claim);
