The above description is only an example, and does not limit the application field of the transaction processing method and apparatus provided by the present invention.
The method and the device for transaction processing can be used in the technical field of computers, the field of block chains, the financial field or other fields, for example, can be used in a business data evidence storage application scene in the financial field. Other fields are any fields other than the computer technology field, the blockchain field, the financial field. The above description is only an example, and does not limit the application field of the transaction processing method and apparatus provided by the present invention.
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying figures and detailed description thereof are described in further detail below. It is to be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application. It should be noted that, for the convenience of description, only a part related to the present application is shown in the drawings, and not all structures are shown.
With the development of the blockchain technology, there are more and more scenarios in which a transaction is associated with multiple blockchains, for example, in a data evidence scenario, there is a need for a business system to store business data into multiple blockchains such as a notary chain, a judicial chain, and an arbitration chain. When any one blockchain or a plurality of blockchain sub-transactions fail, for example, when the transaction is overtime or unidentified, the data of a plurality of blockchain certificates associated with the transaction are inconsistent, the log of the whole transaction is checked manually, and after the transaction is determined to be totally unsuccessful, a new original transaction is manually resubmitted. However, the transaction processing method can only manually check the transaction log and manually resubmit a new original transaction, which is a heavy workload and consumes a large amount of resources.
Based on this, the embodiment of the present application provides a processing method for a transaction associated with multiple blockchains, which supports automatic reissue of a failed sub-transaction without re-initiating a complete original transaction. In a specific implementation, the method may include, for example: acquiring first reissue information of a first sub-transaction of a target transaction from a reissue table, wherein the reissue table is generated when an unsuccessful sub-transaction exists in the target transaction, the unsuccessful sub-transaction comprises the first sub-transaction, the first reissue information comprises a first identifier, a first state and transaction data of the first sub-transaction, the first state is used for indicating that the first sub-transaction is in a reissuable state, and the first identifier is used for identifying a first block chain corresponding to the first sub-transaction; subsidizing the transaction data to the first blockchain based on the first reissue information; and responding to the successful uploading of the transaction data to the first block chain, modifying the first state in the first reissue information into a second state, and obtaining second reissue information, wherein the second reissue information comprises the second state, and the second state is used for indicating that the first sub-transaction is in a state of being not reissued.
Therefore, by the method, when normal transaction is carried out, when the uplink sub-transaction of the target transaction fails, the reissue information of the sub-transaction which fails in transaction is recorded in the reissue table, the reissue information comprises the reissue state of the sub-transaction which fails in transaction, the reissue table is read, the sub-transaction which is in the reissue state is found out for reissuing, if the reissue is successful, the state is updated to be 'not reissue', and repeated reissue is avoided.
To facilitate understanding of a specific implementation of the transaction processing method provided by the embodiments of the present application, the following description is made with reference to the accompanying drawings.
A description will be given of a scenario to which the embodiment of the present application is applied. Referring to the system shown in fig. 1, the system may include a service client 11, a service client 12, a transaction processing device 20, a blockchain 31, a blockchain 32, and a blockchain 33. Wherein, the service client 11 and the service client 12 can transmit the service data to all or part of the blockchains 31, 32 and 33 through the transaction processing device 20. The process that a business client sends business data to a corresponding block chain is called a transaction, the transaction can be divided into a plurality of sub-transactions according to the number of the related block chains, the number of the sub-transactions is consistent with the number of the block chains related to the transaction, and the sub-transactions are in one-to-one correspondence with the block chains. For example, transaction 1 may refer to that the service client 11 may transmit service data a to the blockchain 31, the blockchain 32, and the blockchain 33 through the transaction processing device 20, and then transaction 1 may be divided into sub-transaction 11, sub-transaction 12, and sub-transaction 13, where sub-transaction 11 refers to that the service client 11 may transmit service data a to the blockchain 31 through the transaction processing device 20, sub-transaction 12 refers to that the service client 11 may transmit service data a to the blockchain 32 through the transaction processing device 20, and sub-transaction 13 refers to that the service client 11 may transmit service data a to the blockchain 33 through the transaction processing device 20.
It should be noted that the transaction processing device 20 may be understood as a device for executing the transaction processing method provided in the embodiment of the present application, and the transaction processing device 20 may be carried in an electronic device or a functional module of the electronic device. The electronic device in the embodiment of the present application may be any device capable of implementing the method for processing a transaction in the embodiment of the present application. Specifically, the detailed structural diagram of the transaction processing device 20 can be seen in the device 300 for transaction processing shown in fig. 3 below.
Fig. 2 is a flowchart illustrating a transaction processing method according to an embodiment of the present disclosure. The method may be applied to the apparatus for transaction processing 20 shown in fig. 1, or may be applied to the apparatus for transaction processing 300 shown in fig. 3, or may be applied to the electronic device 400 shown in fig. 4.
As shown in fig. 2, the method may include the following S201 to S203:
the method includes the steps of S201, obtaining first reissue information of a first sub-transaction of a target transaction from a reissue table, wherein the reissue table is generated when an unsuccessful sub-transaction exists in the target transaction, the unsuccessful sub-transaction includes the first sub-transaction, the first reissue information includes a first identifier, a first state and transaction data of the first sub-transaction, the first state is used for indicating that the first sub-transaction is in a reissuable state, and the first identifier is used for identifying a first block chain corresponding to the first sub-transaction.
It should be noted that the reissue table is a concept provided in the embodiment of the present application, and is used to record relevant information of sub-transactions in which a transaction fails due to reasons such as timeout and record lock in a transaction process, so as to provide a data basis for implementing the transaction reissue mechanism provided in the embodiment of the present application.
As an example, before S201, the method may further include: and S200, generating the supplementary table according to the log table. Wherein the log table includes first log information for the first sub-transaction, the first log information including: the first identification, the transaction data and first indication information, wherein the first indication information is used for indicating that the first sub-transaction fails. In particular, the first log information may be divided into a transmission table and a reception table according to actions performed by a device performing transaction processing of the method, wherein the transmission table may include the transaction data and the first identifier, and the reception table may include the first identifier and the first indication information.
The first identifier mentioned in the embodiments of the present application may include, but is not limited to: the system comprises a transaction code, a serial number and a serial number, wherein the transaction code is used for indicating interfaces of a plurality of blockchains related to the target transaction, the serial number is used for identifying the target transaction, and the serial number is used for identifying the first sub-transaction.
For example, assuming that the target transaction is initiated by the service client 11 in the system shown in fig. 1, the transaction code of the target transaction is T1, the external serial number is 1234, the sent request message 1 carries transaction data a, the serial number of the target transaction is 0, the serial number of the sub-transaction 1 is 1, the serial number of the sub-transaction 2 is 2, and the serial number of the sub-transaction 3 is 3, optionally, the transaction processing device 20 may further define an internal serial number 1 for the target transaction, and then the transaction processing device 20 may record a sending table (which may also be referred to as a sending log table) as shown in table 1 below:
TABLE 1
Internal running number Serial number Transaction code External running number Request message
1 0 T1 1234 -
1 1 T1 1234 Request message 1 (transaction data a)
1 2 T1 1234 Request message 1 (transaction data a)
1 3 T1 1234 Request message 1 (transaction data a)
If the sub-transaction 1 and the sub-transaction 2 fail, and the sub-transaction 3 succeeds, the return messages fed back to the transaction processing device 20 by the blockchain 31, the blockchain 32, and the blockchain 33 are the return message 1, the return message 2, and the return message 3, respectively, where for the sub-transaction that fails in transaction, the transaction processing device 20 may also not receive the return message for a preset time (e.g., 3 minutes), and the embodiment of the present application describes that the return message is received but the transaction fails. Optionally, the return message may also be recorded in a receiving table of the transaction processing apparatus 20, and the receiving table (also referred to as a receiving log table) recorded on the transaction processing apparatus 20 may be, for example, as shown in table 2 below:
TABLE 2
Figure BDA0003568841280000091
Then, the transaction processing device 20 may look up table 2 to determine the sub-transactions with the indication information of failure as sub-transaction 1 and sub-transaction 2, so as to record the related information (which may also be referred to as log information) of sub-transaction 1 and sub-transaction 2 into the reimbursement table, which may include: the external serial number, the transaction code, the serial number and the reissue status may optionally include any one or more of a request message, an internal serial number and a reissue serial number. The reissue table in this example can be seen, for example, in table 3 below:
TABLE 3
Figure BDA0003568841280000092
It should be noted that, when a target transaction is initiated, the request message sent by each uplink sub-transaction, the received return message, and the related information of each sub-transaction may be recorded in the sending table and the receiving table. When a certain uplink sub-transaction fails to be executed, the related information of the corresponding uplink sub-transaction can be synchronized to the reissue table, and the status is set as 'reissuable'. After the normal flow of all uplink sub-transactions of the target transaction, a reissue flow can be executed, namely, the reissue table is read to reissue the sub-transactions with the state of 'reissuable', if the reissue is successful, the state is updated to 'not reissue', and the repeated reissue is avoided; if the transaction fails after reissuing the preset number of times (such as 3 times), the transaction result of the target transaction failure, the related information of the sub-transaction causing the failure, and the like can be sent to the service client for subsequent processing.
Taking the system shown in fig. 1 as an example, the transaction processing apparatus 20 may store a corresponding relationship between the transaction code and an interface of the access block chain of the transaction processing apparatus 20, for example, T1 corresponds to interface 1 of the access block chain 31, interface 2 of the access block chain 32, and interface 3 of the access block chain 33, and in a normal flow of the target transaction, the transaction processing apparatus 20 may determine to forward the transaction data a from interface 1, interface 2, and interface 3 to block chain 31, block chain 32, and block chain 33, respectively, according to the transaction code T1 of the target transaction. In the reimbursement process, the transaction processing device 20 may determine to forward the transaction data a from the interface 1 to the blockchain 31 according to the transaction code T1 corresponding to the "reissuable" sub-transaction 1 in the reissue table, or may determine to forward the transaction data a from the interface 2 to the blockchain 32 according to the transaction code T1 corresponding to the "reissuable" sub-transaction 2 in the reissue table.
The external serial number is used to distinguish between different transactions, and even if the transaction codes are the same, the use of the external serial number can determine that the two transactions are different. For example, the transaction codes of transaction 1 and transaction 2 initiated by the service client 1 are both T1, the external serial number of transaction 1 is 1234, and the external serial number of transaction 2 is 4321, so that different contents of the two transactions can be distinguished based on the external serial numbers.
The sequence numbers are used for indicating different sub-transactions in the same transaction, and the sequence number of the sub-transaction of each transaction can be increased from 1 or can be designed according to the requirement.
The internal serial number, which may be defined for different streams within the transaction processing device, is an optional entry in the various tables used for recording in the embodiments of the present application.
S202, based on the first reissue information, reissuing the transaction data to the first block chain.
In a specific implementation, the transaction processing device may generate a request message of the first sub-transaction based on the first reissue information, and send the request message to the first block chain. Alternatively, the transaction processing device may obtain a request packet of the first sub-transaction in the normal flow based on the first reissue information, and send the request packet to the first block chain.
It should be noted that the first reissue information in the reissue table may not include the request message, and then the transaction processing device may obtain the request message corresponding to the first sub-transaction from the sending table based on other contents (such as the external serial number, the serial number, and the transaction code) in the first reissue information, and then send the request message to the first block chain.
S203, responding to the successful uploading of the transaction data to the first block chain, modifying the first state in the first reissue information into a second state, and obtaining second reissue information, wherein the second reissue information comprises the second state, and the second state is used for indicating that the first sub-transaction is in a state of non-reissue.
Therefore, the reissue is realized in a targeted manner aiming at the first sub-transaction which fails in the normal process, and after the first sub-transaction is successfully reissued, the state of the first sub-transaction in the reissue table is modified to be 'unremittable', so that the repeated reissue of the same sub-transaction is avoided, and the resource waste is avoided.
If the reissue table also includes third reissue information for a second sub-transaction of the target transaction, then the method may further include:
s204, obtaining third reissue information, wherein the third reissue information comprises a second identifier, a third state and the transaction data of the second sub-transaction, the third state is used for indicating that the second sub-transaction is in a reissuable state, and the second identifier is used for identifying a second block chain corresponding to the second sub-transaction;
s205, based on the third reissue information, reissuing the transaction data to the second block chain;
s206, responding to the successful uploading of the transaction data to the second block chain, modifying the third state in the third reissue information into a fourth state, and obtaining fourth reissue information, wherein the fourth reissue information comprises the fourth state, and the fourth state is used for indicating that the second sub-transaction is in a state of non-reissue.
The relevant description of S204 to S206 can refer to the above S201 to S203, and is not described herein again.
Wherein the second identifier may include: the system comprises a transaction code, a serial number and a serial number, wherein the transaction code is used for indicating interfaces of a plurality of blockchains related to the target transaction, the serial number is used for identifying the target transaction, and the serial number is used for identifying the second sub-transaction. The transaction code and serial number in the first identifier and the second identifier may be the same for the same target transaction.
The execution order of S204 to S206 and S201 to S203 is not limited, and S204 to S206 may be executed first and then S201 to S203 may be executed, S201 to S203 may be executed first and then S204 to S206 may be executed, or S204 to S206 and S201 to S203 may be executed simultaneously.
In some implementations, if all "reissuable" sub-transactions in the target transaction are completed in the reissue flow, the method may further include: and if the reissue information of all the sub-transactions of the target transaction in the reissue table indicates that the corresponding sub-transactions are in a non-reissue state, determining that the target transaction is finished.
It should be noted that, if a certain sub-transaction is subjected to one reissue, and the reissue is not successful, the state of the sub-transaction in the reissue table may not be modified, and the reissue may be continued. The transaction processing device may preset an upper limit of the reimbursement number of each sub-transaction (i.e., the preset number of times, e.g., 3 times), and if the reimbursement number of one sub-transaction reaches the upper limit of the reimbursement number, may send an alarm signal to the service client to notify the service client that the target transaction cannot be completed.
