Wherein, referring to FIG. 1 , it is a schematic diagram of a cross-organizational blockchain system provided by an embodiment of the present application. The inter-organizational blockchain system includes a blockchain organization A, a blockchain organization B, a blockchain organization C, and a blockchain organization D. Among them, the communication between various blockchain organizations is realized through the cross-chain gateways in each blockchain organization.

Referring to Figure 1, blockchain organization A includes cross-chain gateway A1, relay chain A2, application chain A3, and application chain A4, where application chain A3 communicates with relay chain A2 through cross-chain gateway A5, and application chain A4 communicates with The relay chain A2 communicates through the cross-chain gateway A6; the blockchain organization B includes the cross-chain gateway B1, the relay chain B2, the application chain B3 and the application chain B4, and the application chain B3 and the relay chain B2 communicate through the cross-chain Chain gateway B5 communicates, application chain B4 and relay chain B2 communicate through cross-chain gateway B6; blockchain organization C includes cross-chain gateway C1, relay chain C2, application chain C3 and application chain C4, of which application chain C3 Communicate with the relay chain C2 through the cross-chain gateway C5, and communicate between the application chain C4 and the relay chain C2 through the cross-chain gateway C6; blockchain organization D includes cross-chain gateway D1, relay chain D2, and application chain D3 and the application chain D4, wherein the communication between the application chain D3 and the relay chain D2 is through the cross-chain gateway D5, and the communication between the application chain D4 and the relay chain D2 is through the cross-chain gateway D6. Among them, the relay chain provides cross-chain services for each application chain in its blockchain organization. The communication connection structure between cross-chain gateways that realize cross-organization communication interaction in each blockchain organization is a ring structure. This is just an example. Other communication connection structures (such as star structure) that can realize inter-communication between cross-chain gateways It can be used, and there is no specific limitation here.

It should be noted that the purpose of setting up cross-chain gateways (such as cross-chain gateway A5 and cross-chain gateway B5) between the relay chain and the application chain is to ensure the integrity of the application chain and the relay chain under the same blockchain organization. Cross-chain interaction, the main functions of the cross-chain gateway include adapting to the cross-chain interaction of the relay chain and the application chain, monitoring or consuming cross-chain events on the relay chain and the application chain.

The above-mentioned inter-organizational blockchain system can realize the requirements of trusted transmission and credible storage between organizations. Here, the blockchain organizations in the cross-organizational blockchain system correspond to different organizations. Here, organizations can be understood as industry organizations or institutions. What needs to be explained is that an organization includes multiple sub-organizations, and the application chain is the blockchain of the sub-organizations. For example, blockchain organization A is a blockchain system under a financial industry organization. There are multiple financial institutions or financial companies in the financial industry organization. Each financial institution or financial company is called a sub-organization. Each sub-organization Corresponds to an application chain. Specifically, the application chain can be an alliance chain, and then the blockchain organization corresponding to the application chain is an alliance chain cluster.

Under this cross-organization blockchain system, cross-chain messages for cross-chain interaction between different application chains include cross-chain messages between application chains under the same blockchain organization and application chains under different blockchain organizations. Cross-chain messages between. Among them, cross-chain messages include cross-chain requests and cross-chain receipts.

Fig. 2 shows a schematic flowchart of the data processing method provided by the present application, wherein the method is applied to the first cross-chain gateway in the first blockchain organization, and the first blockchain organization includes the first cross-chain gateway and At least one first application chain, referring to Figure 2, the detailed description of the data processing method is as follows:

S201, the first cross-chain gateway acquires the first historical interaction information stored in the first blockchain organization, the first historical interaction information is the interaction information between the first application chain and the second application chain, and the second application chain is the interaction information between the first application chain and the second application chain. The application chain in the second blockchain organization.

Among them, the first cross-chain gateway is used to realize the cross-chain interaction between the first blockchain organization and other different blockchain organizations.

Optionally, the first historical interaction information includes a first message sequence number and first message content corresponding to the first message sequence number. Wherein, the first message content is the message content of the cross-chain interaction between the first application chain and the second application chain.

It should be noted that the interaction information between the first application chain and the second application chain includes interaction information of the first information type and interaction information of the second information type.

Wherein, the first information type is the information type of the interaction information sent by the first application chain to the second application chain. Specifically, the first information type includes a first information subtype and a second information subtype, where the first information subtype is the information subtype for which the first application chain sends an interaction request message to the second application chain, and the second information subtype The type is the information subtype of the interaction receipt message sent by the first application chain to the second application chain.

The second information type is the information type of the interaction information sent by the second application chain to the first application chain. Specifically, the second information type includes a third information subtype and a fourth information subtype, where the third information subtype is the information subtype for which the second application chain sends an interaction request message to the first application chain, and the fourth information subtype The type is the information subtype of the interaction receipt message sent by the second application chain to the first application chain.

For each sub-type of information, set the initial message number of the corresponding message to 0, and each time a sub-type of interaction message is obtained between the first application chain and the second application chain, the message of the sub-type of interaction message obtained before Add 1 to the sequence number, and use it as the message sequence number of the interaction message of the subtype currently obtained.

Optionally, the first historical interaction information is stored in the first application chain. Correspondingly, step S201 may specifically include: the first cross-chain gateway acquires the first historical interaction information stored in the first application chain.

It should be noted that the acquisition of the first historical interaction information by the first cross-chain gateway through the first application chain needs to be carried out in a trusted environment, which has high requirements for the reliability of the environment. If the environment becomes untrustworthy, the data on the application chain may be at risk of leakage. Therefore, from the perspective of high availability of data, the data will be more secure by adopting the relay chain method. The reason is that the data interaction between different application chains in the same blockchain organization is consensused through the relay chain, and then stored in the corresponding application chain, and the data interaction between application chains of different blockchain organizations is also It needs to be consensused through their respective relay chains, and then stored in the corresponding application chain, which can ensure the security of the data on the application chain.

To sum up, if the method of the embodiment of the present application is applied to the scenario shown in FIG. 1 , the first blockchain organization also includes the first relay chain. Wherein, the first relay chain and the first application chain respectively store the first historical interaction information.

In order to ensure the security of data on the first application chain, the first cross-chain gateway obtains the first historical interaction information stored in the first relay chain.

S202. The first cross-chain gateway acquires second historical interaction information stored in the second blockchain organization, where the second historical interaction information is the interaction information between the second application chain and the first application chain.

In this step, the structure of the second blockchain organization is the same as that of the first blockchain organization. The second blockchain organization includes a second cross-chain gateway and multiple second application chains.

Among them, the second cross-chain gateway is used to realize the cross-chain interaction between the second blockchain organization and other different blockchain organizations.

It should be noted that since the first application chain is an application chain in the first blockchain organization, and the second application chain is an application chain in the second blockchain organization, the historical interaction information between the two, that is, the first The interaction information between an application chain and the second application chain is stored in the first blockchain organization and the second blockchain organization respectively, which facilitates subsequent information comparison and data recovery.

Optionally, the second historical interaction information includes a second message sequence number and a second message content corresponding to the second message sequence number. Wherein, the second message content is the message content of the cross-chain interaction between the second application chain and the first application chain.

Optionally, the second historical interaction information is stored in the second application chain. Correspondingly, step S202 may specifically include: the first cross-chain gateway obtains the second historical interaction information stored in the second application chain through the second cross-chain gateway.

It should be noted that on the side of the second blockchain organization, the second cross-chain gateway obtains the second historical interaction information through the second application chain, which needs to be carried out in a trusted environment, which has a high degree of environmental credibility. requirements. If the environment becomes untrustworthy, the data on the application chain may be at risk of leakage. Therefore, from the perspective of high availability of data, the data will be more secure by adopting the relay chain method. See step S201 for details and will not repeat them here.

To sum up, if the method of the embodiment of the present application is applied to the scenario shown in FIG. 1 , the second blockchain organization also includes a second relay chain. Wherein, the second relay chain and the second application chain respectively store the second historical interaction information.

In order to ensure the security of data on the second application chain, the first cross-chain gateway obtains the second historical interaction information stored in the second relay chain through the second cross-chain gateway.

S203. The first cross-chain gateway compares the first historical interaction information with the second historical interaction information to obtain a first comparison result.

It can be known from the above that the first historical interaction information includes the first message sequence number and the first message content corresponding to the first message sequence number, and the second historical interaction information includes the second message sequence number and the second message content corresponding to the second message sequence number. Therefore, the first cross-chain gateway compares the first historical interaction information with the second historical interaction information, which can be achieved by comparing the message sequence number, or by comparing the message content.

S204. If the first comparison result indicates that the first historical interaction information is inconsistent with the second historical interaction information, the first cross-chain gateway updates the first historical interaction information according to the first comparison result.

Here, if the comparison between the first historical interaction information and the second historical interaction information is realized by comparing the message sequence numbers, the first comparison result indicates that the first historical interaction information is inconsistent with the second historical interaction information. The first message sequence number is different from the second message sequence number; if the comparison between the first historical interaction information and the second historical interaction information is realized by comparing the message content, the first comparison result indicates that the first historical interaction information and the second historical interaction information The inconsistency of the historical interaction information is specifically represented by the fact that the content of the first message is different from the content of the second message, that is, the content of the messages in the corresponding historical interaction information is inconsistent.

In a possible implementation manner, the implementation process of step S201 may include:

In step S2011, the first cross-chain gateway obtains the first service list stored in the first blockchain organization, and the first service list includes all historical interaction information of all application chain services for cross-chain transmission through the first blockchain organization.

It should be noted that the application chain service can be understood as the smart contract on the application chain or part of the data in the ledger on the chain.

Among them, all application chain services for cross-chain transmission through the first blockchain organization include application chain services affiliated to the first blockchain organization and application chain services affiliated to other blockchain organizations.

Here, other blockchain organizations include the second blockchain organization, the third blockchain organization, and the like.

The historical interaction information of application chain services affiliated to other blockchain organizations includes the historical interaction information of application chain services affiliated to the second blockchain organization and the historical interaction information of application chain services affiliated to the third blockchain organization, etc. .

Step S2012, the first cross-chain gateway filters out the third historical interaction information in the first service list to obtain the fourth historical interaction information, wherein the third historical interaction information includes the application chain service station belonging to the first blockchain organization The historical interaction information between each first application chain in the corresponding first blockchain organization, and the first application chain in the first blockchain organization corresponding to the application chain service belonging to the first blockchain organization and other The historical interaction information between the application chains in the blockchain organization; the fourth historical interaction information includes the application chains in other blockchain organizations corresponding to the application chain services of other blockchain organizations and the first block Historical interaction information between the first application chains in the chain organization.

Step S2013, the first cross-chain gateway classifies the fourth historical interaction information according to the identification of the blockchain organization, and obtains a plurality of fifth historical interaction information, wherein each fifth historical interaction information belongs to other blockchain organizations Corresponding to the application chain service of a blockchain organization in , the historical interaction information between the application chain in the blockchain organization and the first application chain in the first blockchain organization.

In step S2014, the first cross-chain gateway uses the identification of the second blockchain organization to select the second application chain and the second application chain service corresponding to the application chain service belonging to the second blockchain organization from a plurality of fifth historical interaction information. The first historical interaction information between application chains.

Correspondingly, in a possible implementation manner, the implementation process of step S202 may include:

According to the identification of the second blockchain organization, the first cross-chain gateway obtains the second historical interaction information stored in the second blockchain organization through the second cross-chain gateway in the second blockchain organization.

It should be noted that, compared with the message content corresponding to the message sequence number, the data of the message sequence number is simpler, and the processing of the message sequence number is more efficient. Therefore, in order to further improve the data processing efficiency, in a possible implementation, the step The implementation process of S203 may include:

Step S2031, the first cross-chain gateway compares the target first message sequence number with the target second message sequence number to obtain the first comparison result, wherein the target first message sequence number is the largest message sequence number among the first message sequence numbers, and the target The second message sequence number is the largest message sequence number in the second message sequence numbers.

Correspondingly, the implementation process of step S204 may include:

Step S2041, if the target first message serial number is greater than the target second message serial number, the first cross-chain gateway obtains the third message content corresponding to the third message serial number stored in the first blockchain organization, and passes the second blockchain The second cross-chain gateway in the organization sends a third message sequence number and third message content to the second application chain, wherein the third message sequence number is a message sequence number in the first message sequence number except the second message sequence number.

It should be noted that the message content in the historical interaction information between the first application chain and the second application chain includes one or more message contents. Correspondingly, the historical interaction information between the first application chain and the second application chain The message sequence number in includes one or more.

Among them, if the target first message sequence number is greater than the target second message sequence number, it means that the number of messages between the first application chain and the second application chain stored in the first blockchain organization is more than that stored in the second blockchain organization. The number of messages between the first application chain and the second application chain, that is, the redundant messages in the first blockchain organization have not been successfully sent to the second application chain in the second blockchain organization before. In order to realize data recovery, the first cross-chain gateway needs to send the third message content corresponding to the third message sequence number to the second application chain through the second cross-chain gateway.

It should be noted that the third message sequence number may be one message sequence number or multiple message sequence numbers, which is specifically determined by the difference between the target first message sequence number and the target second message sequence number. For example, if the first message sequence number includes 1, 2, 3, 4, and 5, and the second message sequence number includes 1 and 2, it means that the messages between the first application chain and the second application chain stored in the second blockchain organization The number is three less than the number of messages between the first application chain and the second application chain stored in the first blockchain organization. At this time, the first cross-chain gateway needs to actively obtain the message number 3 from the first blockchain organization. , 4, and 5 cross-chain messages, and finally send the cross-chain messages with message numbers 3, 4, and 5 to the second application chain under the second blockchain organization through a point-to-point connection with the second cross-chain gateway.

Step S2042, if the target first message sequence number is smaller than the target second message sequence number, the first cross-chain gateway obtains the fourth message content corresponding to the fourth message sequence number stored in the second blockchain organization, and sends the first application chain to the first application chain. Four message sequence numbers and fourth message contents, and add the fourth message sequence numbers and fourth message contents to the first historical interaction information, wherein the fourth message sequence numbers are messages other than the first message sequence numbers in the second message sequence numbers serial number.

Here, if the target first message sequence number is less than the target second message sequence number, it means that the number of messages between the first application chain and the second application chain stored in the first blockchain organization is less than that stored in the second blockchain organization. The number of messages between the first application chain and the second application chain, that is, the redundant messages in the second blockchain organization have not been successfully sent to the first application chain in the first blockchain organization before. In order to achieve data recovery, the first cross-chain gateway needs to obtain the redundant messages in the second blockchain organization through the second cross-chain gateway, and send them to the first application chain, and send the redundant messages in the second blockchain organization The message is updated to the first historical interaction information.

It should be noted that the fourth message sequence number may be one message sequence number or multiple message sequence numbers, which is specifically determined by a difference between the first message sequence number and the second message sequence number. For example, the first message sequence number includes 1 and 2, and the second message sequence number includes 1, 2, 3, 4, and 5, which means that the messages between the first application chain and the second application chain stored in the second blockchain organization The number is three more than the number of messages between the first application chain and the second application chain stored in the first blockchain organization. At this time, the first cross-chain gateway needs to obtain the second blockchain organization through the second cross-chain gateway. The cross-chain messages with message numbers 3, 4, and 5 stored in , and the cross-chain messages with message numbers 3, 4, and 5 are sent to the first application chain, and updated to the first historical interaction information.

Compared with the message content corresponding to the message sequence number, the data of the message sequence number is simpler, and the processing of the message sequence number is more efficient. A possible implementation of step S203 is given above, that is, by comparing the message sequence numbers to achieve The update of data makes the data update processing more efficient.

Since the interaction data between the first application chain and the second application chain are stored in both the first blockchain organization and the second blockchain organization, the data update processing is also performed based on the data in the two blockchain organizations . So further, before comparing the message serial numbers, the first cross-chain gateway only needs to obtain the message serial number corresponding to the message content of the cross-chain interaction between the first application chain and the second application chain, and there is no need to obtain additional messages The message content corresponding to the serial number, that is, the first cross-chain gateway only obtains the message serial number in the historical interaction information, which can further improve the efficiency of data update processing while saving data processing resources.

The above data processing process is the process of updating the historical interaction information between the application chains of the blockchain organization after the cross-chain gateway is started. After the update of the historical interaction information is completed, the cross-chain gateway enters the normal operating state.

For a cross-organization blockchain system composed of different blockchain organizations, refer to Figure 1. Through the above method, each blockchain organization only needs to pay attention to the cross-chain interaction related to its own blockchain organization, without traversal and storage and The cross-chain interaction irrelevant to its own blockchain organization greatly improves the data recovery efficiency when the cross-chain gateway starts.

After the cross-chain gateway enters the normal operation state, when the application chains of different blockchain organizations perform cross-chain interaction, the target application chain needs to process these cross-chain messages in the order of cross-chain messages. However, due to network instability and other reasons, the destination application chain may receive subsequent cross-chain messages when the destination application chain fails to receive the message, so that although the destination application chain receives subsequent messages, It cannot be processed in time, and there is a risk of message blocking and service unavailability.

In order to solve the above problem, referring to FIG. 3, in a possible implementation, the above method further includes:

S301, when the first cross-chain gateway detects the first interaction information between the first application chain and the second application chain, the first cross-chain gateway obtains the fifth historical interaction information, wherein the first interaction information includes the fifth message sequence number and the fifth message content corresponding to the fifth message number, the fifth historical interaction information is the interaction information between the first application chain and the second application chain before receiving the first interaction information, and the fifth historical interaction information includes the sixth message The sequence number and the content of the sixth message corresponding to the sequence number of the sixth message.

Referring to the description in the implementation manner shown in FIG. 1 , the first interaction information is interaction information of a first information type or interaction information of a second information type.

If the first interaction information is interaction information of the first information type, the first interaction information is a first interaction request message or a first interaction receipt message sent by the first application chain to the second application chain.

If the first interaction information is interaction information of the second information type, the first interaction information is a second interaction request message or a second interaction receipt message sent by the second application chain to the first application chain.

Here, when the first cross-chain gateway monitors the first interaction information between the first application chain and the second application chain, it indicates that cross-chain interaction is currently required between the first application chain and the second application chain. The cross-chain interaction between the first application chain and the second application chain has been processed accordingly, and the first cross-chain gateway needs to obtain the fifth historical interaction information.

Here, the first cross-chain gateway may obtain the fifth historical interaction information from the corresponding chain that stores the fifth historical interaction information.

The first cross-chain gateway can also obtain the fifth historical interaction information from the local memory, that is, the first cross-chain gateway maintains the interaction sequence number between the first application chain and the second application chain after each execution of the cross-chain message , to reduce network communication interactions and improve network performance.

Because there is only one cross-chain gateway connected to the application chain at a time, the cross-chain gateway can maintain the interaction sequence number between the application chains, and if the cross-chain gateway maintains the interaction sequence number between the application chains, the data processing efficiency is higher. Of course, the application chain and the relay chain also maintain the interaction sequence number between the application chain, which can be obtained when the cross-chain gateway is down and recovers.
