In the embodiment of the application, the target service processing is completed, that is, the service instruction corresponding to the target service is completed by execution. In the process of processing and storing the target service, the problems of invalid signature, failure in verification of the hash value of the service, failure in passing through security authority, system failure and the like may occur, so that after the processing of the target service is completed, whether the target service is abnormal needs to be judged, and the abnormal service is prevented from affecting the normal processing and storage of other services and affecting the throughput of the system. The target service is abnormal, which indicates that the processing of the target service fails, and at the moment, the service data corresponding to the target service cannot be stored in the blockchain, and the service data corresponding to the target service needs to be rolled back.

The second buffer space is used for storing service data corresponding to a plurality of services in the block; in a possible implementation manner, the second buffer space may be a buffer space on the target node or may be a buffer space on another node, and the size of the second buffer space may be larger than that of the first buffer space, so that there is enough space to store service data corresponding to a plurality of services. The target service is not abnormal, which indicates that the target service is normally processed, at the moment, the target service data in the first cache space can be stored into the second cache space of the blockchain, and then the first cache space is emptied; in this case, the first buffer space is emptied to facilitate the processing of the next service, that is, the service data generated by the service instruction corresponding to the next service is stored in the first buffer space.
In the embodiment of the application, the service data generated by each service instruction corresponding to the target service are stored in the first cache space, and under the condition that the abnormality exists in the target service, the data in the first cache space is timely emptied, so that rollback of the service data corresponding to the target service can be realized only by emptying the first cache space, the processing and storage of other services are not influenced, and the throughput of a system is improved; and under the condition that the target service is not abnormal, storing the service data corresponding to the target service in the first cache space into the second cache space, so that the safety of the service data stored in the blockchain is ensured.
According to the business data processing method provided by the embodiment of the invention, whether the target business is abnormal or not is determined after the business data corresponding to the target business is stored in the first buffer space and before the business data corresponding to the target business is stored in the second buffer space, so that when the target business is abnormal, the rollback of the business data corresponding to the target business can be realized by only emptying the first buffer space, the processing and storage of other businesses are not affected, the problem that the normal storage of other businesses stored in the whole block in which the business is stored is affected by the rollback of the execution state of all businesses in the whole block in the prior art is solved, and the throughput of a system is improved.

In the embodiment of the application, the first type represents that the target service has an abnormality due to system failure, and the abnormality is serious, and the first cache space can be directly under the condition; furthermore, the first type of exception does not have any assistance in the handling of subsequent traffic and therefore does not require storage.
Wherein, the second type representation target service is abnormal because of not conforming to the service processing condition.
In the embodiment of the present application, the first exception cause is an exception that a service instruction corresponding to a target service exists in an execution process or an exception that an execution result of the service instruction is stored. The second type represents the target business and has the abnormality because of not conforming to the business process condition, this abnormality is abnormality in the business process, the possible abnormality is caused by user account have mistake, invalid signature, not accord with the situation such as the security policy, can confirm the reason of abnormality correspondent abnormality at this moment, facilitate knowing the abnormal condition of the target business subsequently, and deal with in time in order to report the business again; in addition, the second type of abnormality is an abnormality in the process of processing the service, and references and warnings are provided for the processing of the subsequent service, so that the first abnormality cause corresponding to the abnormality can be determined.
In the embodiment of the application, the abnormality and the first abnormality cause can be stored in the second cache space, so that the subsequent acquisition of the abnormality condition of the target service is facilitated, and the processing is timely carried out to report the target service again. And storing the first abnormal reason into the second buffer space, and then emptying the first buffer space so as to facilitate the subsequent processing of the next service. In one possible implementation, the anomalies and the first cause of the anomaly may be stored to the second cache space in KV pairs.
The second buffer space is used for storing service data corresponding to a plurality of services in the block chain.
In the embodiment of the application, the abnormality existing in the target service is divided into different abnormality types, different processing modes are adopted for the different abnormality types, and the service data corresponding to the target service can be directly emptied for the abnormality existing in the target service due to the system fault, so that the buffer space can be saved; for the abnormality of the target service due to the fact that the target service does not accord with the service processing conditions, determining a first abnormality reason of the abnormality, storing the first abnormality reason into a second buffer space, facilitating the follow-up acquisition of the abnormality of the target service, and timely processing to re-report the target service.

According to the business data processing method provided by the embodiment of the invention, whether the target business is abnormal or not is determined after the business data corresponding to the target business is stored in the first buffer space and before the business data corresponding to the target business is stored in the second buffer space, so that when the target business is abnormal, the rollback of the business data corresponding to the target business can be realized by only emptying the first buffer space, the processing and storage of other businesses are not affected, the problem that the normal storage of other businesses stored in the whole block in which the business is stored is affected by the rollback of the execution state of all businesses in the whole block in the prior art is solved, and the throughput of a system is improved.
Based on the foregoing embodiments, an embodiment of the present application provides a service data processing method, referring to fig. 3, including the following steps:
The first buffer space is used for storing service data generated by a service instruction corresponding to the current service.
The third buffer space is used for storing service data corresponding to the current service.
In the embodiment of the application, the first buffer space stores service data generated by each service instruction corresponding to the target service, namely the first buffer space aims at the service instruction, and isolation of the service data of the service instruction is realized; the third buffer space stores target service data in the first buffer space, namely the third buffer space aims at target service, and isolation of service data corresponding to the service is realized, so that the safety of the service data is further ensured.
In the embodiment of the application, whether the target service is abnormal or not is determined based on the target service data in the third cache space, so that the risk of system faults can be eliminated, and the safety of the service data is further ensured.
In one possible implementation manner, whether the target service is abnormal or not may be determined based on an execution result corresponding to each service instruction stored in the third buffer space; if there is an exception in submitting the target data from the first cache space to the second cache space, then the stored results may be reported at this time.
It should be noted that, after step 303 is performed, step 304 or step 305 may be performed.
In the embodiment of the application, whether the target service is abnormal or not is determined through the target service data in the third buffer space, and only the first buffer space and the second buffer space have data at the moment, so that the first buffer space and the third buffer space can be emptied under the condition that the target service is determined to be abnormal, the safety of a system is ensured, and the processing and storage of other services are prevented from being influenced by the abnormal service.
Wherein step 304 may be implemented by:

It should be noted that, since the first abnormality cause is determined directly by the service data in the first buffer space, and the second abnormality cause is determined by the service data in the second buffer space, an abnormality may occur when data is submitted from the first buffer space to the second buffer space, and thus the second abnormality cause may be different from the first abnormality cause.
And step 304d, the target node stores the second abnormal reason in the second cache space, and empties the first cache space and the third cache space.
The second buffer space is used for storing service data corresponding to a plurality of services in the block chain.

In one possible implementation, the exception and the second cause of the exception may be stored to the second cache space in KV pairs.
In step 305, the target node stores the target service data in the third buffer space to the second buffer space and empties the first buffer space and the third buffer space when it is determined that the target service is not abnormal.
In the embodiment of the present application, in the case that it is determined that there is no abnormality in the target service, the target service data in the third buffer space is stored in the second buffer space and the first buffer space and the third buffer space are emptied, so as to facilitate the processing of the next service, that is, the service data generated by the service instruction corresponding to the next service is stored in the first buffer space.
In other embodiments of the present application, if a system exception occurs during the process of submitting data from the third buffer space to the second buffer space, if the second buffer space already stores data, then the data in the second buffer space needs to be rolled back, and the third buffer space and the first buffer space are emptied, and since the service data in the third buffer space is stored in the second buffer space from the service perspective, the rolling back is performed for the service data of the target service, so that the processing of other services is not affected. And after passing through the first buffer memory space and the second buffer memory space, the service data corresponding to the target service is stored in the second buffer memory space, so that not only can the target service be ensured to be free from abnormality in the processing process, but also the service data can be further ensured to be free from abnormality in the storage process, the safety of the service data stored in the second buffer memory space is ensured to the greatest extent, and the safety of a blockchain system is further ensured.
In the embodiment of the application, instruction isolation is realized through the first cache space, business isolation is realized through the second cache space, block isolation is realized through the third cache space, interference and pollution of abnormal business to other businesses are reduced, repeated submission and processing of normal business caused by one-cut block rollback in the prior art are avoided, system throughput is submitted, and safety of a block chain is ensured.
