Bridge between the Off-Chain Physical Oracle (PTVS v1.0) and the RWA Tokens
1. Architecture of the Physical Oracle in Environments Web3
Tokenization of real-world assets (RWA) at the institutional level requires intelligent compliance contracts (compliance smart contracts) to react not only to on-chain data, but to real physical conditions of the underlying asset. The contract PTVSClaimInjector.sol acts as unexpugnable middleware between encrypted expert evidence (QFER) and the standard of institutional tokens ERC-3643 (T-REX).
2. Smart Contract Execution Flow
- Safe Data Intake: The system processes satellite telemetry (Google Earth Engine) and audit metadata performed in Confidable Execution Environments (VMs / TEE Confidential GCP).
- Hash Generation of Evidence: Seal cryptographically the information under the RFC 3161 / eIDAS 2.0 standard, generating a unique hash of integrity (SHA-256).
- On-Chain injection: Through the function of the injector, the claims are updated in accordance with the Real Asset Identifier (RWA ID).

4. Integration in the Pilot of €50M
This contract is part of the reference deployment in the project gee-ptvs-oracle-poc on Google Cloud, allowing to automate protection mechanisms (*Circuit Breakers*) against physical discrepancies detected in property and infrastructure audits.
