After receiving a request for storing the consumption financial service data sent by the mobile terminal, the blockchain node checks the storage space and determines whether the blockchain node receives the consumption financial service data instruction according to the storage space of the blockchain node;
Aiming at the situation that the block chain node has a storage space, the block chain node sends and receives a financial business data consumption instruction to the mobile terminal;
Aiming at the condition that the block chain node has no storage space, the block chain node sends an instruction for not receiving the consumption financial business data to the mobile terminal.
Specifically, establishing network connection between the mobile terminal and the block link point, and further comprising;
When the block chain node has a storage space and receives a request for storing the consumption financial business data sent by the mobile terminal, extracting the residual storage space of the block chain node;
When the residual storage space of the block chain node is lower than a preset first space threshold, the current block chain node is determined to be the condition without the storage space;
When the residual storage space of the block chain node is not lower than a preset first space threshold value but is lower than a preset second space threshold value, the residual storage space occupation capacity of the block chain link point in unit time is evaluated, and an evaluation parameter is obtained; wherein the evaluation parameter is obtained by the following formula:
Wherein H represents an evaluation parameter; h 0 denotes a preset evaluation parameter reference value; e represents a constant; n represents the number of unit time that the current block chain link point has undergone; c 01i represents the amount of data stored in the blockchain node for the ith unit time; c 02i represents the amount of freed data of the memory space within the i-th unit time blockchain node; c p represents the average throughput of data processing per unit time for the current blockchain node;

The technical effects of the technical scheme are as follows: the technical scheme allows the blockchain node to dynamically manage the storage space of the blockchain node. By monitoring the remaining storage space of the node and judging according to a preset space threshold, the node can automatically judge whether enough storage space exists to process the request. By evaluating the memory space occupation capability of the blockchain node, the memory resources of the node can be better utilized. This helps to improve the utilization efficiency of storage resources and reduce resource waste. By rejecting new requests for credentials when storage space approaches a limit, nodes can be prevented from crashing or degrading due to insufficient storage space. This helps to improve the stability and reliability of the system.
The calculation of the evaluation parameters of the technical scheme is automatically carried out without manual intervention. This makes storage space management more automated and intelligent. Through effective management of storage resources, the system can be ensured to process the user request in time, and user experience is improved. At the same time, service interruption or delay due to insufficient storage space is avoided.

And acquiring a space release amount by using the stored occupied space and the residual storage space, wherein the space release amount is acquired by the following formula:
Wherein C represents the space release amount; c y1 and C y2 represent a preset first spatial threshold and a second spatial threshold, respectively; h y denotes a preset parameter threshold; c s represents the remaining memory space of the current blockchain node; c z represents the stored footprint of the current blockchain node;
And performing storage space release on the blockchain node according to the space release amount.
The technical effects of the technical scheme are as follows: the system can monitor the number of times that the blockchain node is identified as having no storage space in real time and make corresponding feedback. This helps to timely grasp the storage state of the node in order to take necessary measures. When the number of times that the blockchain node is determined to have no storage space exceeds a preset number of times threshold, the system automatically triggers the release operation of the storage space. This ensures that the node is not in an unrecoverable state for a long time, thereby improving the usability of the system. : by calculating the amount of space released, the system can automatically release an appropriate amount of storage space according to the storage condition of the node. This helps to optimize the use of storage resources, avoiding over-release or under-release situations.
The automatic memory space release function helps to maintain the stability of the system. When the storage resources are close to the limit, the automatic release of the storage space can prevent the system from crashing or degrading due to insufficient storage space. The system can automatically manage the storage space, and reduces the need of manual intervention. This reduces maintenance and management costs while improving the reliability of the system.
The above technical solution of the present embodiment helps to achieve dynamic and automatic storage space management and release, so as to ensure that the system can maintain high availability and performance when processing mobile terminal requests.
