Linking NFTs to real-world property rights typically requires cooperation with national notary nodes to ensure legal validity and enforceability. NFTs, as blockchain-based tokens, can represent ownership digitally, but real-world assets like property or intellectual rights often need official recognition. National notary systems provide trusted, legally binding verification of ownership, transfers, or contracts, bridging the gap between decentralized blockchain records and centralized legal frameworks. Without such cooperation, NFT ownership may lack legal weight in disputes or transfers, risking unenforceability. Collaboration with notary nodes can standardize processes, enhance trust, and ensure compliance with local laws, making NFT-linked property rights practical and secure.
