DUAL-CHAIN PROPERTY MANAGEMENT SYSTEM FOR THE TOKENIZATION OF ALL THINGS

Resumen de: US2025200682A1

The present invention introduces a dual-chain property management system that integrates blockchain-based tokens with off-chain government and institutional property records to provide secure, verifiable, and legally recognized asset transactions. Unlike existing blockchain-based property solutions, this system prevents unauthorized tokenization, enforces compliance with jurisdictional property laws, and synchronizes title records dynamically. A concurrency management module eliminates double-minting risks, while a discrepancy resolution engine continuously detects and corrects mismatches between blockchain and legal registries. Smart contracts automate ownership transfers, lease agreements, lien tracking, and compliance enforcement, ensuring fraud-resistant transactions in real estate, vehicles, intellectual property, luxury goods, and financial instruments. This innovation enables legally binding digital property transfers with real-time regulatory oversight, bridging the gap between decentralized asset tokenization and traditional legal frameworks. By automating verification, synchronization, and compliance, the system creates a scalable, transparent, and jurisdictionally compliant property management ecosystem.
