Specifically, each NFT has a unique identifier, which is usually composed of a string or a number. This identifier is associated with the asset in the smart contract, ensuring the uniqueness and  traceability of the asset. In addition, each block in the blockchain network contains a certain number of smart contracts responsible for managing issues such as issuance, trading, and ownership of NFT assets. By indexing blocks and smart contracts, we can find specific NFT assets."}]}],"pr":"c4cefa962054310b5b6faf2b1ec91046addf19ce04744500ff0c0813280640d4"}
