Space, which is the console of authorized data. One space corresponds to one authorized account. When the master account is authorized to other accounts, the corresponding master account space will be generated under the authorized account, and only authorized data and authorized operations can be availbale in the sub-account space. For example: If account A is authorized to account B, account C, there will be an account A space in account B and account C. Example 2: If account A and account B are both authorized to account C, their space will be separately in account C. There are two spaces for account A account B individually.
