Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The block chain is essentially a shared database, and data or information stored in the block chain has the characteristics of 'non-counterfeiting' and 'trace in the whole process', so that the block chain can be integrated into the transfer process of a traditional bank system, for example, in the cross-border payment scene, the block chain can be used as a 'middleman' for third party accounting. However, in the transfer process involving the block chain, one party of the bookkeeping party is a bank system, and the other party is the block chain, so that the consistency of withholding and posting cannot be ensured by using a traditional bank record mode (storing withholding and posting data in the same database and relying on the database underlying transaction technology to keep consistency) or a mode of a third party organization (such as global banking inter-finance Telecommunications association, Society for world across Financial inter-bank Financial Telecommunications communications, SWIFT). Therefore, it is necessary to provide a processing method and apparatus for transaction consistency based on blockchain to ensure the consistency of transactions.
Fig. 1 to 4 are schematic diagrams illustrating a main flow of a processing method for transaction consistency based on blockchain according to an embodiment of the present invention, as shown in fig. 1, the method includes:
step S101: a first transaction request is received, the first transaction request indicating a transaction amount.
In an embodiment of the present invention, the first transaction request may be a transfer request, and the transaction amount may be a transfer amount. The first transaction request also indicates a payment account number, a collection account number, and a transaction identification. For example, the first transaction request may be a transfer request for transferring money from a bank account to a blockchain, or may be a transfer request for transferring money from a blockchain to a bank account, the transfer request indicating the transfer amount. Each transaction has a unique transaction identification, and the transaction data corresponding to the transaction can be inquired according to the transaction identification. For example, the transaction identification may be a transaction serial number.
In the embodiment of the invention, in the process of each transaction (or transfer), the steps of deducting account and posting account are included, wherein the deducting account can be a multi-party deducting account, for example, when N (N is a natural number greater than 2) bank accounts transfer to the block chain, the deducting account of the N bank accounts can be sequentially performed according to the sequence, after the deducting account of all the N bank accounts is completed, the posting account of the block chain is performed, and the posting account amount is the sum of the amounts of the deducted account of the N bank accounts. The posting can also be multi-party posting, such as block link posting, and then posting on N bank accounts respectively.
In the embodiment of the invention, when the first transaction request is received, the transaction state corresponding to the transaction identifier and the first transaction request is recorded. The transaction identification is the only identification of the transaction, such as a transaction serial number, and the transaction data corresponding to the transaction can be inquired according to the transaction identification; the transaction status (or trace record) corresponding to the first transaction request records the status of the transaction, for example, when the first transaction request is received, the transaction status corresponding to the first transaction request may be recorded as "expected", which indicates that the first transaction request is about to be executed. By recording the transaction state, the following transaction is possible or certain to occur under the condition that the transaction state record exists, and if the transaction state is not recorded, the transaction is not occurred. If the 'prediction' of the transaction state is not recorded, account deduction processing is directly carried out, and in the process of the account deduction operation, abnormal server downtime occurs, so that the source cannot be traced when the service is restarted.
Step S102: and sending the first transaction request to a transaction system, so that the transaction system carries out transaction according to the transaction amount.
In the embodiment of the present invention, the transaction system may be, for example, a bank host system, that is, the transaction may be a transaction between the bank host system and the blockchain. And the transaction system receives the first transaction request and carries out transaction according to the transaction amount. When the transaction system executes the transaction, the residual amount of the account of the payer is reduced, and the transaction flow is recorded. Wherein the residual amount of the payer account is the amount before executing the account deduction operation. For example, when a transfer request is initiated by a bank account a, the transaction system receives the transfer request, and executes a charge operation according to the transfer amount, so as to reduce the remaining amount in the account a, wherein the reduced amount is the transaction amount.
Step S103, responding to the transaction exception of the transaction system, and executing asynchronous processing corresponding to the first transaction request by adopting a first asynchronous processing thread.
In the embodiment of the present invention, before step S103, the method further includes:
step 201: in response to the transaction system not returning a result for the first transaction request, sending an inquiry request to the transaction system, and recording a first current number of times the inquiry request is sent; and when the first current times is greater than a preset first threshold value, determining that the transaction of the transaction system is abnormal.
In the embodiment of the invention, after the transaction system receives the first transaction request and executes the transaction according to the transaction amount, the transaction execution result is returned in a communication mode.
In the embodiment of the present invention, when the transaction system does not return the result of the request for the first transaction due to the downtime of the server or the network anomaly, that is, the result of the first transaction request returned by the transaction system is not received within the preset time, it is necessary to send the query request to the transaction system, query the result of the first transaction request, and record the first current number of times of sending the query request (i.e., the number of times of querying).
In the embodiment of the invention, when the first current number is not greater than the preset first threshold, the transaction system is determined to be successful or unsuccessful in transaction for the first transaction request in response to the feedback of the transaction system for the query request. That is, within the number of queries with the preset first threshold, when sending the query request to the transaction system, the transaction system feeds back the transaction result according to the query request, and if the query is successful, the transaction state corresponding to the first transaction request may be updated to "successful", and step S104 is executed; if the query is a failure, the transaction is failed, the transaction status corresponding to the first transaction request may be updated to "failure", and step S202 is executed.
In an embodiment of the present invention, the query request may be sent to the transaction system according to a transaction identifier (e.g., a transaction serial number).
In the embodiment of the invention, when the first current times is greater than a preset first threshold, the transaction system is determined to be abnormal in transaction.
In the embodiment of the invention, when the transaction system is determined to have abnormal transaction, the transaction is interrupted, the transaction state is updated to be abnormal, and the transaction failure-to-be-funded rollback can also be returned.
In the embodiment of the invention, when the transaction system has abnormal transaction, the first asynchronous processing thread is adopted to execute the asynchronous processing corresponding to the first transaction request.
In an embodiment of the present invention, the method further includes:
step S202: interrupting the transaction in response to a transaction failure of the transaction system for the first transaction request.
In the embodiment of the invention, after the information of the transaction failure of the first transaction request returned by the transaction system is received, the transaction is ended. The transaction failure may be caused by insufficient remaining amount of the account, account fund blocking or locking, and the like.
Step S104: in response to a transaction success of the transaction system, sending a second transaction request to the blockchain in accordance with an execution result of the first transaction request, the second transaction request indicating the transaction amount.
In an embodiment of the present invention, the first transaction request is a withholding request for a transaction system, and the second transaction request is an posting request for a blockchain.
In the embodiment of the invention, when the transaction system returns the transaction success result, the transaction state corresponding to the first transaction request is updated to be 'transaction success', namely the account deduction is successful; and then sending a second transaction request to the blockchain, wherein the second transaction request indicates the transaction amount, and meanwhile, recording a transaction state corresponding to the second transaction request, for example, recording that the transaction state corresponding to the second transaction request is "expected", which indicates that an accounting operation corresponding to the second transaction request is to be executed.
In an embodiment of the present invention, the method further includes:
responding to a message of successful account deduction returned by the transaction system, and generating first transaction information according to default transaction information and transaction amount;
sending an account posting request to the blockchain according to the first transaction information;
and processing the first transaction information to restore the default transaction information in response to the message of the account posting failure returned by the blockchain.
In an embodiment of the present invention, the first transaction information is obtained according to a sum of a default value indicated by the default transaction information and the transaction amount.
Before receiving an account deduction request, default transaction information is set in a transaction consistency processing device based on a block chain, the default transaction information indicates a default value, when a transaction system returns an account deduction success message, transaction amount is increased on the basis of the default value to obtain first transaction information, an account posting request is sent to the block chain according to the first transaction information, when the block chain returns an account posting failure message, the block chain is proved to be failed to enter account, then the first transaction information is processed, and the first transaction information is restored to the default transaction information. For example, the default value indicated in the default transaction information is 0, the remaining amount in the account a of the banking system is 100 yuan, when 10 yuan is transferred to the blockchain from the account a of the banking system, if the banking system returns that the account a deducts 10 yuan successfully, the first transaction information is obtained, and the first transaction information is obtained by the sum of the default value and the transaction amount, namely 0+ 10; entering the posting of the block chain, if the posting failure is returned by the block chain, processing the first transaction information, and restoring the first transaction information to a default value of 0, namely restoring the default transaction information.
In the embodiment of the invention, the block link receives the transaction second transaction request, performs transaction according to the transaction amount and feeds back the transaction result. For example, the blockchain receives an account posting request, the account posting request indicates a transaction amount, the blockchain performs an account posting operation according to the transaction amount, and increases the remaining amount of the blockchain account, where the increased amount is the transaction amount.
In an embodiment of the present invention, the method further includes:
step S301: and in response to the blockchain not returning feedback for the second transaction request, sending a query request to the blockchain, and recording a second current number of times the query request is sent.
In the embodiment of the present invention, when the server is down or the network is abnormal, and the transaction result for the second transaction request returned by the blockchain is not received, the query request is sent to the blockchain, the query request may be sent to the blockchain according to the transaction identifier to query the transaction result for the second transaction request, and the second current number of times (i.e., the number of times of query) for sending the query request is recorded.
When the second current number of times is not greater than the preset second threshold, if the transaction result is successfully inquired, updating the transaction state corresponding to the second transaction request to be 'transaction successful', and executing step 204, determining that all transactions performed according to the transaction amount are successful, namely the transactions aiming at the second transaction request are successful, namely the posting is successful, and ending the transaction; if the query transaction result is failure, updating the transaction state corresponding to the second transaction request to be "transaction failure", and executing step 205, executing the inverse transaction corresponding to the second transaction request; and if the transaction result is not inquired, continuously sending an inquiry request to the blockchain.
When the second current number of times is greater than the preset second threshold, no query request is sent to the blockchain any more, the blockchain transaction is determined to be abnormal, the transaction state corresponding to the second transaction request is updated to be abnormal, the transaction is interrupted, and step S105 is executed, and the transaction abnormal-to-be-asynchronously-processed identifier can be recorded.
In an embodiment of the present invention, the method further includes:
step S302: determining whether the transaction for the second transaction request was successful in response to feedback of the blockchain for the second transaction request.
In the embodiment of the invention, after the block chain executes the transaction of the posting request, the posting result is fed back, and meanwhile, the transaction state aiming at the posting request is updated so as to judge whether the transaction aiming at the posting request is successful.
Step S303: when the transaction for the second transaction request is successful, it is determined that the transactions performed according to the transaction amount are all successful.
And when the transaction aiming at the second transaction request is successful, updating the transaction state corresponding to the second transaction request to be 'transaction successful', and at the moment, if the transaction system deducts account successfully and the block chain enters account successfully, indicating that the transfer from the transaction system to the block chain is successful, the transaction is completed and the transaction is ended.
Step S304: and when the transaction aiming at the second transaction request fails, executing the reverse transaction corresponding to the second transaction request.
And when the transaction aiming at the second transaction request fails, updating the transaction state corresponding to the second transaction request to be transaction failure, and executing the reverse transaction corresponding to the second transaction request, namely when the block chain returns to the posting failure, updating the transaction state to be posting failure, and executing the forward (rollback) transaction of the posting.
Step S305: in response to success of the reverse transaction corresponding to the second transaction request, the reverse transaction corresponding to the first transaction request is executed.
In the embodiment of the present invention, when the reverse transaction corresponding to the second transaction request is executed, if the corresponding transaction status is updated to be "reverse transaction successful" with respect to the reverse transaction corresponding to the second transaction request, the reverse transaction corresponding to the first transaction request is executed, that is, the posting is successful, and then the posting is executed.
Step S306: responding to the failure of the reverse transaction corresponding to the second transaction request, continuing to execute the reverse transaction corresponding to the first transaction request, and recording the first execution times; and if the first execution times is greater than a preset third threshold value or the reverse transaction is abnormal, executing asynchronous processing corresponding to the second transaction request by adopting the first asynchronous processing thread.
In the embodiment of the present invention, when executing the posting and checking transaction, if the posting and checking transaction is returned and fails, the corresponding transaction state is updated to be "checking failure", and the posting and checking orthogonal transaction is continuously executed, and at the same time, the first execution time is recorded, that is, the time for executing the posting and checking transaction is recorded, if the first execution time is greater than the preset third threshold, step S105 is executed, the transaction is interrupted, the transaction state is updated to be "checking orthogonal transaction abnormal", and the transaction identifier can also be recorded as "transaction abnormal-to-be-funded rollback".
When the reverse transaction corresponding to the second transaction request is executed, if a transaction result of the reverse transaction corresponding to the second transaction request is not received, sending an inquiry request to the blockchain according to the transaction identifier to inquire the transaction result of the reverse transaction, and recording the second execution times, if the inquiry result is that the reverse transaction is successful, executing step S305, if the inquiry result is that the reverse transaction is failed, executing step S305, and if the inquiry result is that the second execution times exceeds a preset fourth threshold value, the inquiry result is not obtained, and executing step S105.
Step S307: in response to a success of executing the inverse transaction corresponding to the first transaction request, a transaction failure corresponding to the transaction amount is determined.
When the reverse transaction corresponding to the first transaction request is executed successfully, namely the deduction and positive reversal are successful, the transaction state of the reverse transaction corresponding to the first transaction request is updated to be 'reverse transaction successful', and the transfer from the transaction system to the block chain is failed, so that the transaction is failed.
Step S308: and in response to the failure of executing the reverse transaction corresponding to the first transaction request, continuing to execute the reverse transaction corresponding to the first transaction request, recording a third execution time, and executing the step S103 when the fourth execution time is greater than a preset fifth threshold.
When the execution of the account deduction and positive reversal fails, updating the transaction state of the reverse transaction corresponding to the first transaction request to be 'reverse transaction failure', continuing initiating the account deduction and positive reversal easy, and executing the step S103, wherein the account deduction and positive reversal easy is not initiated until the number of the account deduction and positive reversal times reaches a preset fifth threshold value.
Step S309: in response to an exception to execute the inverse transaction corresponding to the first transaction request, executing asynchronous processing corresponding to the first transaction request with a first asynchronous processing thread.
When the transaction result of the inverse transaction corresponding to the first transaction request is not received, sending an inquiry request to the transaction system, and recording the frequency of the inquiry request, namely the fourth execution frequency, if the inquiry transaction result is that the inverse transaction is successful, executing step S307; if the query transaction result fails to additionally reverse the transaction, executing S308; if the fourth execution time is greater than the preset sixth threshold value and the transaction result is not obtained yet, it is determined that the reverse transaction is abnormal, the transaction state of the reverse transaction corresponding to the first transaction request is updated to be "reverse transaction abnormal", and step S103 is executed.
Step S105: and responding to the transaction exception of the blockchain, and executing asynchronous processing corresponding to the second transaction request by adopting a first asynchronous processing thread.
In an embodiment of the present invention, executing asynchronous processing corresponding to the first transaction request and/or the second transaction request by using a first asynchronous processing thread includes:
acquiring abnormal transaction data;
and determining whether all the transactions aiming at the transaction amount are successfully executed according to the abnormal transaction data, if so, determining whether all the inverse transactions aiming at the transaction amount are successfully executed, and when all the inverse transactions are failed, determining that all the transactions aiming at the transaction amount are successfully executed.
Wherein the abnormal transaction data indicates an abnormal condition that the server is down and/or the transaction execution result cannot be obtained.
In the embodiment of the invention, when a first transaction request (a deduction request) and/or a second transaction request (an account posting request) are/is asynchronously processed, abnormal transaction data about abnormal request conditions that a server is down and/or a transaction execution result cannot be obtained are obtained, wherein the abnormal transaction data comprises transaction abnormal identification; and according to the abnormal transaction data, judging whether all transactions of the transaction amount are successfully executed in a reverse order, namely whether all transactions of account deduction and account posting are successfully executed, if all transactions are successfully executed, namely, the transactions of account deduction and the transactions of account posting are successfully executed, judging whether all transactions of account deduction and account posting are successful, and if all transactions of account deduction and account posting are failed, indicating that all transactions are successfully executed, namely, the transactions transferred from the transaction system to the block chain are successful.
