Of course, the service information may be stored in a plurality of block node devices, and since the total data amount of resources of storage resources of different block node devices is not necessarily the same, the resource availability ratio of the target account may be defined in the intelligent contract, and the method may be applied to a case where only the service information is stored in the information storage device, for example: the current information storage device manages two accounts, a and B, and can limit the amount of available data of resources of account a to 70%, the amount of available data of resources of account B to 30%, and so on. Taking the resource available information as the resource available data amount as an example, the information storage device may obtain a resource used data amount of the storage resource currently used by the target account, and further may obtain remaining resource usage information corresponding to the target account in the storage resource based on the resource available data amount and the resource used data amount, where the remaining resource usage information may specifically be a resource remaining data amount corresponding to the target account in the storage resource.

Of course, the service information may be stored in a plurality of block node devices, and since the total data amount of resources of storage resources of different block node devices is not necessarily the same, the resource availability ratio of the target account may be defined in the intelligent contract, and the method may be applied to a case where only the service information is stored in the information storage device, for example: the current information storage device manages two accounts, a and B, and can limit the amount of available data of resources of account a to 70%, the amount of available data of resources of account B to 30%, and so on. Taking the resource availability information as the resource availability ratio as an example, the information storage device may obtain a total resource data amount of storage resources of at least one block node device used for managing a target account in the service block chain, may obtain a resource availability ratio of the storage resources of the target account in an intelligent contract, and finally obtain a resource availability data amount corresponding to the target account based on the total resource data amount and the resource availability ratio, and optionally, the resource availability data amount is a product of the total resource data amount and the resource availability ratio.
