First, the metadata of NFT is usually stored in smart contracts on the blockchain, which are written according to specific standards (such as ERC721) to  ensure the uniqueness and traceability of each NFT. Second, the consensus mechanism of the blockchain (such as proof of work, proof of stake, etc.) ensures the security and immutability of the data. Once the metadata is written into the blockchain, any attempt to tamper with the metadata will face difficulties."}]}],"pr":"ab09ab2eb060aa854be34c6c5410b5be04f338cfaaaca63581aed44c75581e08"}
