The tree structure applied in NFT can effectively reduce redundant data and improve the efficiency of data storage and query. In NFT, tree structures are usually used to represent the relationships between different attributes, such as all the permissions and assets owned by a user. Through tree structures, it is convenient to manage and query these relationships.\n\nA set is an unordered and non-repeating collection of elements. In NFT, sets are used to store and query information in a more flexible and efficient way. Sets can represent the unique attributes of each NFT, such as token IDs, ownership information, and transaction records. The main advantage of using sets in NFT is that they can easily handle the complexity of the underlying data and provide fast access"}]}],"pr":"51efa5ca79bc33527f74e988932f927d1c0edde522d9b53af8137b334e65e200"}
