Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 is a flowchart of steps of a method for controlling transaction data storage according to an embodiment of the present invention, as shown in fig. 1, and is applied to a server including a cache data space, where the server communicates with a blockchain for storing transaction data, and the method may include:
In a specific application, after receiving a user request, a server sends the user request to a corresponding blockchain, and the blockchain generates transaction acceptance information corresponding to the user request according to the user request to indicate that the user request is already put into a transaction pool of a blockchain system to be used as a transaction to be executed.
And 102, acquiring the transaction acceptance information returned by the blockchain, wherein the transaction acceptance information is generated by the blockchain according to the user request.
In the prior art, it is usually the case that a user request is responded only after a transaction to be executed is completed, that is, when a transaction message is blocked (a block on a blockchain), that is, the blocking time of the transaction message is the response time of the user request, which results in a long response time, and the user needs to wait for a long time before knowing the execution result of the user request. According to the technical solution provided by the present invention, as shown in fig. 2, after the user request is put into the transaction pool of the blockchain, a transaction acceptance information is fed back to the user (the initiator of the user request) to indicate that the transaction request has been accepted by the blockchain and is in a state to be executed. For example, the fed back transaction acceptance information may be a transaction hash value, and the transaction hash value may be obtained by converting the user identifier corresponding to the user request and the transaction identifier corresponding to the transaction request into hash values and splicing the two hash values.
It should be noted that the blockchain referred to in the present invention refers to one or more blockchain networks, and supports automatic or manual flexible expansion of the blockchain network, and supports automatic or manual flexible expansion or contraction of nodes inside the blockchain network, for example, a federation chain or a private chain of a house, an EOS, or a super book, and may also perform standard operations supported by blockchain technologies such as user creation, account transaction, intelligent contract invocation, transaction query operations, and the like.
By returning the transaction information to the initiator, the initiator is enabled to quickly learn that its user request has been accepted, for example.
And 104, when the transaction corresponding to the user request is completed, receiving a transaction result corresponding to the user request and sent by the block chain, and storing the transaction result in the cache data space.
For example, after receiving the user request, the server determines a transaction operation corresponding to the user request, and determines transaction information corresponding to the transaction operation, for example, the transaction information may include: the identification of the transaction order, the transaction content information, etc., and then forward the transaction information corresponding to the user request and the transaction operation to the blockchain, the blockchain may put the transaction operation corresponding to the user request into the transaction pool after returning the transaction acceptance information for the user request according to step 102, specifically, one or more transaction operations may be stored in the transaction pool of the blockchain, and the transaction operation may be regarded as a transaction operation to be executed (i.e., a received but unexecuted transaction), the blockchain may be able to pass through a preset execution period, so that the transaction operation in the transaction pool is executed within the execution period, and after the execution is completed, the generated transaction result is fed back to the server, so that after the server receives the transaction result, the transaction result is stored in the cache data space, and the information in the cache data space is updated, then, the following step 105 is utilized to confirm the execution result of the uplink operation of the user request according to the transaction result, when the transaction result is successful, the successful uplink is indicated, and the successful uplink of the user request is confirmed; otherwise, when the uplink is not successfully performed, the uplink operation needs to be repeatedly performed to finally ensure that the uplink is successful.
And 105, under the condition that a result returning instruction sent by the initiator is received, obtaining a transaction result of the transaction corresponding to the result returning instruction from the cache data space, and sending the transaction result to the initiator.
In a specific application, as shown in fig. 2, after the transaction result corresponding to the user request is stored in the cache data space, the server may obtain the transaction result of the transaction corresponding to the result return instruction from the cache data space under the condition that the result return instruction is received, and send the transaction result to the initiator, so as to inform the user (initiator) that the user request has been executed and that the execution result is successful or unsuccessful.
It should be noted that, preferably, the transaction service includes a large amount of transaction information with high usability and low security sensitivity, for example, transaction information such as user score classification and voting, and the technical solution proposed by the present invention can be used to store and manage the transaction through the off-link (server), so as to reduce the transaction delay, improve the user experience, and reduce the service pressure of the blockchain system. For example, the above type of transaction is marked in advance, and when the transaction with the mark is identified, the technical scheme provided by the invention is adopted to perform corresponding operation.
In summary, the control method for transaction data storage provided by the present invention forwards the received user request to the block chain; acquiring transaction acceptance information returned by the blockchain, wherein the transaction acceptance information is generated by the blockchain according to a user request; returning the transaction acceptance information to the initiator of the user request; when the transaction corresponding to the user request is completed, receiving a transaction result corresponding to the user request and sent by the block chain, and storing the transaction result into a cache data space; and under the condition of receiving a result returning instruction sent by the initiator, acquiring a transaction result of the transaction corresponding to the result returning instruction from the cache data space, and sending the transaction result to the initiator. Therefore, the invention can firstly quickly respond to the user request through the transaction acceptance information fed back by the block chain, and promote the transaction response speed of the block chain.
Optionally, fig. 3 is a flowchart illustrating specific steps of a method for controlling transaction data storage according to an embodiment of the present invention, as shown in fig. 3:
In an implementation manner of the embodiment of the present invention, fig. 4 is a flowchart illustrating specific steps of a control method for storing transaction data according to the embodiment of the present invention, and as shown in fig. 4, step 201 may specifically include steps 2011 to 2013:
The user request comprises the trading order information corresponding to the user request.
Illustratively, the trade order information is used for uniquely identifying the trade information in the user request, according to which the trade content can be corresponded.
In addition, the server may set an access gateway, configured to parse the obtained user request based on a predetermined rule, verify the user request, and determine whether the user request is legal, that is, perform the operation in step 2012. In addition, the access gateway can also support the functions of authority management, flow control management and control and safety.
In a specific application, whether the user request meets the verification condition is judged, which can be specifically realized by the following modes:
the method comprises the steps that whether a user request meets an authentication condition or not can be determined by judging whether trade order information included in the user request is legal or not, and if the trade order information is legal, the user request is considered to meet the authentication condition; and if the trade order information is illegal, the user request is considered not to meet the verification condition. Specifically, firstly, the trade order information in the user request can be extracted, the trade order information is matched with a legal trade order template stored in the server, if the trade order information is matched with the legal trade order template, the trade order information is determined to be legal, and the user request is considered to meet the verification condition; and if not, determining that the transaction order information is illegal, and considering that the user request meets the verification condition.
The second mode is that the user request can be verified according to the account information in the transaction order information to determine whether the account information is abnormal or not, so as to determine whether the user request meets the verification condition or not, and if the account information is not abnormal, the user request is considered to meet the verification condition; and if the account information is abnormal, the user request is considered not to meet the verification condition. Specifically, the account state of the account information in the transaction order information may be monitored, and if an abnormal state tag (e.g., a state tag such as a word forbidden, a seal number, etc.) exists in the account due to illegal operation by a user or reporting by another user, it is determined that the account information is abnormal, and the user request is considered not to satisfy the verification condition; and if the account does not have the abnormal state label, confirming that the account information is not abnormal, and considering that the user request meets the verification condition.
And thirdly, whether the user corresponding to the account information is an authorized user can be confirmed through a preset authorization list, so that whether the user request meets the verification condition is determined. If the user corresponding to the account information is an authorized user, the user request is considered to meet the verification condition; and if the user corresponding to the account information is not an authorized user, the user request is considered not to meet the verification condition. Specifically, an authorized user list may be preset, an account user is determined through account information in the transaction order information, if the account user is on the authorized user list, the user corresponding to the account information is determined to be an authorized user, and the user request is considered to meet the verification condition; and if the account user is not on the authorized user list, confirming that the user corresponding to the account information is not an authorized user, and considering that the user request does not meet the verification condition.
And fourthly, whether the account corresponding to the account information has enough money or not can be confirmed through a preset money threshold value, so that whether the user request meets the verification condition or not is determined. If the total amount of remaining money in the account is greater than or equal to a preset money threshold, the user request is considered to meet the verification condition; and if the total amount of remaining money in the account is smaller than a preset money threshold value, the user request is considered not to meet the verification condition.
Illustratively, the user request meeting the verification condition is sent to the blockchain, so that the blockchain puts the user request into the transaction pool to be executed.
In a specific application, after the user request is put into the transaction pool, the blockchain generates transaction information corresponding to the user request, encrypts the correspondingly generated transaction information and sends the encrypted transaction information to the server, so that the server sends the encrypted transaction information as transaction acceptance information to the initiator, for example, converts the transaction information into a hash value and returns the hash value to the server, so that the server responds to the initiator (user) of the transaction request, for example, feeds the hash value of the transaction information as transaction acceptance information back to the initiator as a transaction execution certificate, which indicates that the user request has been accepted and is in a to-be-executed state.
This step may specifically refer to step 103, which is not described herein again.
Optionally, the user request includes trade order information of a trade corresponding to the user request; after the step 203, the method may further include:
For example, the first correspondence between the transaction order information and the transaction acceptance information is stored in the cache data space, so that the information corresponding to the user request is conveniently recorded and traced, and since the transaction acceptance information only indicates that the user request is accepted, there is a high probability that the user request will be successfully executed, but since the actual transaction execution result is not yet obtained, storing the transaction acceptance information in the cache data space enables the user request to be corresponded to after the final actual transaction execution result, i.e., the transaction result, is obtained in step 104, and thus the correct transaction result can be fed back to the initiator of the user request.
Optionally, fig. 5 is a flowchart illustrating specific steps of a control method for storing transaction data according to an embodiment of the present invention, as shown in fig. 5, step 205 may specifically include:
Wherein the transaction result comprises success or failure.
For example, after the blockchain execution completes the transaction corresponding to the user request, the transaction result is sent to the server, which indicates whether the user request is successful or not. The server stores the second corresponding relation between the transaction result corresponding to the user request and the transaction acceptance information, ensures the data correspondence and validity, is convenient to feed back to the initiator of the user request in batches, and informs the initiator of the specific user request of the initiator.
And step 206, under the condition that a result returning instruction sent by the initiator is received, obtaining a transaction result of the transaction corresponding to the result returning instruction from the cache data space, and sending the transaction result to the initiator.
In addition, transaction results requested by a plurality of users are stored in the cache data space, batch processing can be performed on the transaction results through a preset scanning period, and corresponding operations are executed corresponding to different transaction results. When the transaction result is successful, the transaction result can be directly fed back to the initiator requested by the user; on the contrary, when the transaction result indicates that the user request is not successful, the compensation operation needs to be performed: and the user request is automatically and repeatedly executed, and the repeated execution time threshold value is set for the user request, so that the efficiency of repeated execution operation is ensured.
Optionally, if the transaction result includes transaction success information, step 206 may be specifically implemented by, under the condition that a result return instruction sent by the initiator is received, obtaining, according to the first corresponding relationship and the second corresponding relationship, a transaction result and transaction order information of a transaction corresponding to the result return instruction from the cache data space, and sending the transaction result and the transaction order information to the initiator.
In the embodiment of the present invention, the corresponding relationship between the transaction-transaction acceptance information-transaction order information-transaction result can be established according to the first corresponding relationship provided in step 204 and the second corresponding relationship provided in step 2052. Under the condition that the transaction result comprises the transaction success information, the transaction corresponding to the transaction can be returned according to the result, the transaction result and the transaction order information corresponding to the transaction are determined, and the transaction result and the transaction order information are sent to the initiator so as to inform the user that the transaction operation corresponding to the transaction order is successfully processed.
Optionally, if the transaction result includes transaction failure information, after step 206, the method may further include:
In this step, since the second request transaction is not successfully executed, the server automatically performs a transaction compensation operation thereon.
Specifically, the (periodic) compensation operation is realized through the cache data space, so that the request transaction can be repeatedly executed under the condition that the transaction result is unsuccessful, the success rate of the request transaction is improved, the server side directly performs the compensation operation, and the user operation can be simplified.
Exemplarily, the trade order information and the corresponding trade result are fed back to the initiator together to inform the initiator that the user requests the completion of the execution of the corresponding trade operation, and if the trade result is successful, the user requests the successful execution of the corresponding trade operation; otherwise, the transaction operation is not successfully executed repeatedly, for example, an alarm is turned on, the number of times of repeated execution exceeds a threshold value, a verification operation for the user request is triggered, for example, the user request is inquired and verified through historical data, the reason why the user request is not successfully executed is found, for example, problems such as abnormal account or abnormal network may occur, the server automatically eliminates the abnormal problems, then the user request is retried, after whether the transaction operation can be successfully executed is confirmed, if the transaction operation is not successfully executed, whether manual intervention is needed can be confirmed again, and error information is manually eliminated.
And step 208, acquiring a new transaction result for the repeated request sent by the blockchain, and updating the transaction result corresponding to the transaction in the cache data space according to the new transaction result.
In this step, the blockchain may generate a new transaction result for the transaction corresponding to the repeated request, and the new transaction result may replace the old transaction result corresponding to the cached data space, so as to ensure timeliness of the data in the cached data space.
Optionally, after step 206, the method may further include:
In the embodiment of the invention, compared with the stability of data stored in the memory, only a part of data with higher timeliness in the memory is stored in the cache, so that the data in the cache can be conveniently and quickly called by the processor, and the response rate is improved.
It should be noted that the data management operation includes, but is not limited to, a deletion or replacement operation on data in the cache data space.
Optionally, in a specific implementation manner of the embodiment of the present invention, step 209 may be specifically implemented by deleting the transaction result in the cache data space after sending the transaction result to the initiator.
In the implementation manner, after the transaction result in the cache data space is sent to the initiator, the transaction result can be considered to be processed, lose invalidity value and be deleted, so that the spare capacity of the cache data space is larger than a preset threshold value according to the processed transaction result which is continuously deleted, the cache data space has enough spare capacity to receive new data, and the timeliness of the data in the cache data space is improved.
Optionally, in another specific implementation manner of the embodiment of the present invention, the transaction result includes a timestamp added when the transaction result is generated; fig. 6 is a flowchart illustrating specific steps of a control method for storing transaction data according to an embodiment of the present invention, and as shown in fig. 6, step 209 may specifically include:
In the embodiment of the present invention, the timestamp is a tag added according to the generation time when the transaction result is generated, and is used to indicate the generation time of the transaction result, and when a plurality of different transaction results exist in the cache data space, the transaction results may be sorted according to the timestamps of the transaction results, so as to obtain a transaction result sequence.
For example, there are three transaction results A, B and C in the cache data space, where the timestamp of transaction result a is 2011, 1 month, 1 day; the timestamp of the transaction result B is 2011, 1 month and 2 days; the time stamp of transaction result C is 2011, 1, 3. The transaction results are sorted in the order of the timestamps from morning to evening to obtain a sequence of transaction results a, B, C.
In this step, referring to the example provided in step 2091 above, for the transaction result sequence [ a, B, C ], assuming that the transaction result a and the transaction result C have already been sent to the initiator and the transaction result B has not yet been sent to the initiator, the transaction result a and then the transaction result C may be deleted in the cache data space, and after the transaction result B is sent to the initiator, the transaction result a may be deleted until the free capacity of the cache data space is greater than the preset threshold, so that the cache data space has a large enough free capacity to receive new data, thereby improving the timeliness of the data in the cache data space.
In summary, the control method for transaction data storage provided by the present invention forwards the received user request to the block chain; acquiring transaction acceptance information returned by the blockchain, wherein the transaction acceptance information is generated by the blockchain according to a user request; returning the transaction acceptance information to the initiator of the user request; when the transaction corresponding to the user request is completed, receiving a transaction result corresponding to the user request and sent by the block chain, and storing the transaction result into a cache data space; and under the condition of receiving a result returning instruction sent by the initiator, acquiring a transaction result of the transaction corresponding to the result returning instruction from the cache data space, and sending the transaction result to the initiator. Therefore, the invention can firstly quickly respond to the user request through the transaction acceptance information fed back by the block chain, and promote the transaction response speed of the block chain. And aiming at the requirement of higher timeliness of the data in the cache data space, the data management operation can be carried out on the data in the cache data space, so that the free capacity of the cache data space is ensured to be larger than a preset threshold value, the cache data space has enough free capacity to receive new data, and the timeliness of the data in the cache data space is improved.
