Linking NFTs to real-world property rights typically requires cooperation with national notary nodes to ensure legal validity and trust. National notary systems can verify ownership, authenticate transactions, and provide legal backing, bridging the digital and physical realms. Without such cooperation, enforcing property rights tied to NFTs faces challenges like fraud, disputes, or lack of legal recognition. For example, real estate or intellectual property linked to NFTs needs official validation to be legally binding across jurisdictions. National notary nodes can standardize processes, ensuring compliance with local laws and enhancing credibility. However, decentralized blockchain systems may resist centralized notary involvement, creating tension between trust and autonomy. Cooperation depends on regulatory frameworks and the willingness of governments to integrate blockchain technology into existing legal systems.
