Description

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a method and a device for processing transaction data.

Background

Currently, a transaction sender device may store transaction data in its cache and in other nodes on the blockchain in which the transaction sender device resides. When the transaction sender device does not belong to the blockchain, or the transaction sender device cannot keep updating synchronously with the transaction data in the blockchain for some reason (e.g., server failure, etc.), the transaction data in the blockchain needs to be sent to the transaction sender device. Specifically, any node (referred to as a target node) in the blockchain may provide the transaction sender device with the transaction data in the blockchain.

However, when the target node is a server in an external data network, since the transaction sender device needs to obtain the transaction data of the block chain from the server (i.e., the target node) in the external data network through a 5G core network (5G core network, 5GC), a time delay for the transaction sender device to obtain the transaction data in the block chain may be long, which affects processing efficiency of the transaction data.

Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

The term "and/or" as used herein includes the use of either or both of the two methods.

In the description of the present application, the meaning of "a plurality" means two or more unless otherwise specified.

Some concepts related to a transaction data processing method and apparatus provided by the embodiments of the present invention are explained below.

The MEC, mobile edge computing, is an open platform constructed by integrating the mobile network technology and the internet technology and adding the functions of computing, storing, data processing and the like on the mobile network side. The deployment of the MEC node can present the characteristics of low time delay, high bandwidth and the like of service data transmission, and can also provide more accurate position information service for users. In the embodiment of the invention, the time delay of the first node for acquiring the transaction data corresponding to the first block chain (namely the block chain corresponding to the target MEC node) can be reduced through the target MEC node determined by the network control equipment.

Based on the problems existing in the background art, embodiments of the present invention provide a method and an apparatus for processing transaction data, where a first node sends a transaction request message and state information of the first node to a network control device, where the transaction request message includes an account address of a second node (i.e., a transaction receiver device corresponding to a target transaction) and transaction data corresponding to the target transaction, and the state information of the first node includes location information of the first node, a block height of the transaction data stored in the first node, and a timestamp of the transaction data stored in the first node; after the network control device receives the transaction request message of the first node and the status information of the first node, it may determine a target MEC node (i.e., a node with the shortest communication distance to the first node) according to the location information of the first node, and determine whether the transaction data stored in the first node is the same as the transaction data corresponding to the first block chain (i.e., the block chain corresponding to the target MEC node) according to the block height of the transaction data stored in the first node and the timestamp of the transaction data stored in the first node. Then, when the transaction data stored in the first node is different from the transaction data corresponding to the first blockchain, the network control device sends a first data synchronization indication message to the first node, where the first data is the same as the indication message and is used for indicating the first node to acquire the transaction data corresponding to the first blockchain from the target MEC node.

The transaction data processing method and apparatus provided in the embodiment of the present invention may be applied to a wireless communication system, taking the wireless communication system as a 5G communication system as an example, as shown in fig. 1, the 5G communication system includes a node 101, a network control device 102, a block chain 103, an overlapping data storage system 104, and a block chain 105, where the block chain 103 includes a node 1031 and a node 1032, the overlapping data storage system 104 includes an overlapping node 1041, and the block chain 105 includes a node 1051 and a node 1052. In general, in practical applications, the connections between the above-mentioned devices or service functions may be wireless connections, and fig. 1 illustrates the connections between the devices by solid lines for convenience of intuitively representing the connections between the devices.

Among them, a plurality of nodes (including the node 101, the node 1031, the node 1032, the node 1051, and the node 1052) illustrated in fig. 1 may serve as a transaction sender device or a transaction receiver device. For example, when node 101 needs to initiate a transaction to node 1031, node 101 may send a transaction request message to control device 102, and in a case that control device 102 determines that node 101 is a node in blockchain 103, node 101 may perform data interaction with node 1031, for example, node 101 may send transaction data to node 1031, that is, two nodes of the same blockchain may implement data interworking.

Network control device 102 may obtain status information for node 101 and data status information for each of blockchain 103 and blockchain 105 and determine whether node 101 is a node in blockchain 103 or blockchain 105. In this embodiment of the present invention, the network control device 102 may determine whether the transaction data stored by the node 101 is the same as the transaction data corresponding to the blockchain 103 (or the transaction data corresponding to the blockchain 105) according to the state information of the node 101 (specifically, the block height and the timestamp of the transaction data stored by the node 101).

Transaction data corresponding to the blockchain 103 and transaction data corresponding to the blockchain 105 are stored in a plurality of nodes (including the node 1031 and the node 1032) in the blockchain 103 and a plurality of nodes (including the node 1051 and the node 1052) in the blockchain 105, respectively. It should be understood that different nodes on the same blockchain store the same transaction data.

The overlapping data storage system 104 (specifically, the overlapping node 1041) stores transaction data corresponding to the blockchain 103 and transaction data corresponding to the blockchain 105. In this embodiment of the present invention, in a case that the network control device 102 determines that the node 101 is one node in the blockchain 103, but the transaction receiver device (assuming that the transaction receiver device is the node 1051) is one node in the blockchain 105, the network control device 102 may instruct the node 101 to obtain transaction data corresponding to the blockchain 105 from the overlapped node 1041.

Optionally, the 5G communication system may include a plurality of block chains, one block chain may include one or more nodes, and may further include one or more network control devices and one or more overlay data storage systems (or overlay nodes). The embodiment of the present invention does not limit the number of each device in the 5G communication system.

For convenience of example, in the following embodiments, the node 101 in fig. 1 described above is collectively referred to as a first node.

The memory 202 includes, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), an erasable programmable read-only memory (EPROM), a flash memory, an optical memory, or the like. The memory 202 holds the code for the operating system.

In the case where the processor 201 implements the processing method of the transaction data provided by the embodiment of the present invention by reading the memory, the memory stores therein an instruction for implementing the processing method of the transaction data provided by the embodiment of the present invention.

The network interface 203 is a wired interface, such as a Fiber Distributed Data Interface (FDDI) interface or a Gigabit Ethernet (GE) interface. Alternatively, the network interface 203 is a wireless interface. The network interface 203 is used for the network control device 20 to communicate with other devices.

The memory 202 is configured to store data status information of each of a plurality of blockchains, where the data status information of one blockchain includes a blockheight of transaction data corresponding to the blockchain and a timestamp of the transaction data. Optionally, the memory 202 is further configured to store a correspondence between an account address of the node and identification information of the blockchain, and the like. The at least one processor 201 further executes the method described in the embodiment of the present invention according to the data state information of each of the plurality of block chains stored in the memory 202 and the correspondence between the account address of the node and the identification information of the block chain. For more details of the above functions implemented by the processor 201, reference is made to the following description of various method embodiments.

Optionally, the network control device 20 further includes a bus, and the processor 201 and the memory 202 are connected to each other through the bus 204, or are connected to each other in other manners.

Optionally, the network control device 20 further comprises an input/output interface 205, and the input/output interface 205 is configured to connect with an input device and receive a transaction request message input by a user through the input device. Input devices include, but are not limited to, a keyboard, a touch screen, a microphone, and the like. The input/output interface 205 is further configured to connect with an output device, and output a processing result of the transaction data of the processor 201 (i.e., instruct the first node to obtain the transaction data corresponding to the first blockchain from the target MEC node). Output devices include, but are not limited to, a display, a printer, and the like.

It should be understood that, in the embodiment of the present invention, the hardware structure of the first node is similar to the hardware structure of the network control device shown in fig. 2, and the description of the hardware structure of the first node may refer to the description of the hardware structure of the network control device, and is not described in detail here.

The transaction data processing method provided by the embodiment of the invention is applied to an application scene that target transaction exists between a certain transaction sender device (such as a first node) and a transaction receiver device (a second node). When a first node needs to send a transaction request to a second node, the first node needs to first send a transaction request message and state information of the first node to a network control device, and the network control device determines whether the first node is a node on a first blockchain and whether the first node and the second node are on the same blockchain.

With reference to the communication system shown in fig. 1, the following fully describes the transaction data processing method provided in the embodiment of the present invention from the perspective of interaction among devices in the communication system, so as to describe a process in which the first node acquires transaction data corresponding to the first blockchain from the target MEC node (i.e., a first node uplink), and a process in which the first node stores the transaction data corresponding to the target transaction in its cache.

As shown in fig. 3, the method for processing transaction data according to the embodiment of the present invention may include S101 to S114.

S101, the first node sends a transaction request message and state information of the first node to the network control equipment.

The transaction request message comprises an account address of a second node and transaction data corresponding to the target transaction, and the second node is transaction receiver equipment corresponding to the target transaction. The state information of the first node includes location information of the first node, a block height of the transaction data stored by the first node, and a timestamp of the transaction data stored by the first node.

It should be appreciated that when a first node needs to initiate a target transaction to a second node (e.g., the first node needs to forward a bitcoin to the second node), a transaction request message and status information of the first node need to be sent to a network control device, and the network control device first determines the current status of the first node (i.e., whether it is a node on a blockchain). The account address of the second node is used to determine identification information of a block chain (hereinafter referred to as a second block chain) corresponding to the second node, and a plurality of nodes on the second block chain may perform transaction verification on transaction data corresponding to the target transaction to determine whether to store the transaction data in respective caches of the plurality of nodes on the second block chain; the position information of the first node is used for determining a target MEC node with the shortest communication distance with the first node, and the first node can further acquire transaction data corresponding to the first block chain from the target MEC node; the block height of the transaction data stored by the first node and the timestamp of the transaction data stored by the first node are used to determine whether the transaction data stored by the first node is the same as the transaction data corresponding to the block chain (hereinafter referred to as the first block chain) corresponding to the target MEC.

S102, the network control equipment receives the transaction request message of the first node and the state information of the first node.

In connection with the above description of the embodiments, it should be understood that the transaction request message of the first node includes the account address of the second node (i.e. the receiver device corresponding to the target transaction) and the transaction data corresponding to the target transaction, and the state information of the first node includes the location information of the first node, the block height of the transaction data stored by the first node, and the timestamp of the transaction data stored by the first node.

Specifically, the location information may be a longitude and latitude of the first node, or an Internet Protocol (IP) address of the first node. The block height of the transaction data stored by the first node may be understood as the number of blocks corresponding to the transaction data stored by the first node, and for example, assuming that 10 transactions of transaction data are included in 1 block, and assuming that the block height of the transaction data stored by the first node is 5 (i.e. the number of blocks corresponding to the transaction data is 5), it may be determined that the first node stores at least 41 transactions of transaction data. The time stamp of the transaction data stored by the first node is the time stamp of the transaction data of the latest transaction stored by the first node.

S103, the network control equipment determines a target MEC node with the shortest communication distance with the first node according to the position information of the first node.

It will be appreciated that in a network there are a plurality of nodes, each of which may provide transaction data for a first node. In this embodiment of the present invention, the network control device determines, from the plurality of nodes, the node having the shortest communication distance to the first node, that is, the target MEC, based on the location information of the first node. The target MEC node is a node on the first blockchain, the node uses the MEC server as infrastructure, and the target MEC node stores transaction data corresponding to the first blockchain. The network control device determines the target MEC node based on the location information of the first node so that the network control device can determine whether the first node is a node on the first blockchain.

S104, the network control equipment determines whether the transaction data stored in the first node is the same as the transaction data corresponding to the first blockchain or not according to the block height of the transaction data stored in the first node and the timestamp of the transaction data stored in the first node.

And the first block chain is a block chain corresponding to the target MEC node.

It should be understood that the target MEC node is a node on the first blockchain, and the transaction data stored in the target MEC node is the transaction data corresponding to the first blockchain. Since the network control device stores (or can acquire) data status information of each of the plurality of blockchains (the data status information of one blockchain includes a blockheight and a timestamp of the transaction data corresponding to the blockchain), the process of the network control device determining whether the transaction data stored by the first node is the same as the transaction data corresponding to the first blockchain may include steps 1 to 3.

Step 1, the network control equipment determines whether the block height of the transaction data stored in the first node is the same as the block height of the transaction data corresponding to the first blockchain.

And 2, the network control equipment determines whether the timestamp of the transaction data stored by the first node is the same as the timestamp of the transaction data corresponding to the first blockchain.

And 3, under the condition that the block height of the transaction data stored in the first node is the same as the block height of the transaction data corresponding to the first blockchain, and the timestamp of the transaction data stored in the first node is the same as the timestamp of the transaction data corresponding to the first blockchain, the network control equipment determines that the transaction data stored in the first node is the same as the transaction data corresponding to the first blockchain. Otherwise, the network control equipment determines that the transaction data stored by the first node is different from the transaction data corresponding to the first blockchain.

For example, assuming that the block height of the transaction data stored in the first node is 4, the timestamp of the transaction data stored in the first node is 08:00, 7/10/2020; the block height of the transaction data corresponding to the first block chain is 5, and the timestamp of the transaction data corresponding to the first block chain is 08:01, 7/10/2020. The network control equipment determines that the transaction data stored by the first node is different from the transaction data corresponding to the first blockchain.

It will be appreciated that all nodes on the same blockchain should store the same transaction data when operating normally. In the case that the network control device determines that the transaction data stored by the first node is the same as the transaction data corresponding to the first blockchain (specifically, the transaction data stored by the node on the first blockchain), it indicates that the first node is a node on the first blockchain. When the network control device determines that the transaction data stored in the first node is different from the transaction data corresponding to the first blockchain, it indicates that the first node is not a node on the first blockchain, and at this time, it needs to instruct the first node to join the first blockchain, that is, instruct the first node to obtain the transaction data corresponding to the first blockchain.

It should be noted that, when a certain node (e.g., the first node) exits a certain blockchain (e.g., the first blockchain) after completing the last transaction, or the first node fails to complete real-time updating of transaction data corresponding to the first blockchain due to network and server performance, etc., the network control device may determine that the first node is not really a node on the first blockchain (it may be understood that the first node is not uplink), and further, need to instruct the first node to complete the uplink (i.e., join the first blockchain) process.

And S105, under the condition that the transaction data stored in the first node is different from the transaction data corresponding to the first blockchain, the network control equipment sends a first data synchronization indication message to the first node.

The first data synchronization indication message is used for indicating the first node to acquire transaction data corresponding to the first blockchain from the target MEC node.

In another implementation, in a case that the transaction data stored by the first node is not the same as the transaction data corresponding to the first blockchain, the network control device may further instruct the target MEC node to send the transaction data corresponding to the first blockchain to the first node.

S106, the first node receives a first data synchronization indication message of the network control equipment.

With reference to the description of the above embodiments, it should be understood that the target MEC node is determined by the network control device according to the location information of the first node, and the first block chain is a block chain corresponding to the target MEC node (the target MEC node is a node on the first block chain).

S107, the first node sends a first data synchronization request message to the target MEC node.

Specifically, the first data synchronization request message is used to request to acquire transaction data corresponding to the first blockchain.

S108, the target MEC node receives a first data synchronization request message of the first node.

S109, the target MEC node sends a first data synchronization response message to the first node.

The first data synchronization response message includes transaction data corresponding to the first blockchain.

S110, the first node receives a first data synchronization response message of the target MEC node.

Therefore, the first node may acquire the transaction data corresponding to the first blockchain, that is, the transaction data stored by the first node and the transaction data corresponding to the first blockchain are kept synchronous, and the first node may serve as a node on the first blockchain, that is, the first node completes the uplink process.

It should be noted that, after S104, in a case that the transaction data stored by the first node is the same as the transaction data corresponding to the first blockchain, the network control device may determine that the first node is a node on the first blockchain, that is, the first node does not need to complete the synchronization process of the transaction data in S105 to S110.

In the method for processing transaction data provided by the embodiment of the present invention, a first node sends a transaction request message and state information of the first node to a network control device, where the transaction request message includes an account address of a second node (i.e., a transaction receiver device corresponding to a target transaction) and transaction data corresponding to the target transaction, and the state information of the first node includes location information of the first node, a block height of the transaction data stored in the first node, and a timestamp of the transaction data stored in the first node; after the network control device receives the transaction request message of the first node and the status information of the first node, it may determine a target MEC node (i.e., a node with the shortest communication distance to the first node) according to the location information of the first node, and determine whether the transaction data stored in the first node is the same as the transaction data corresponding to the first block chain (i.e., the block chain corresponding to the target MEC node) according to the block height of the transaction data stored in the first node and the timestamp of the transaction data stored in the first node. Then, when the transaction data stored in the first node is different from the transaction data corresponding to the first blockchain, the network control device sends a first data synchronization indication message to the first node, where the first data is the same as the indication message and is used for indicating the first node to acquire the transaction data corresponding to the first blockchain from the target MEC node.

And S111, the network control equipment determines the identification information of the second block chain according to the account address of the second node.

The second block chain is a block chain corresponding to the second node, that is, the second node is a node on the second block chain.

In connection with the above description of the embodiments, it should be understood that, after receiving the transaction request message and the status information of the first node from the first node, the network control device first determines whether the first node is a node on the first blockchain based on the status information of the first node. After the network control device determines that the first node is a node on the blockchain, or after the first node acquires (or synchronizes) the transaction data corresponding to the first blockchain from the target MEC node, the network control device performs S111 again.

It is to be understood that the network control device may store in advance a correspondence relationship between the account address of the node and the identification information of the blockchain, and the network control device may determine the identification information of the second blockchain corresponding to the account address of the second node from the correspondence relationship.

Specifically, all nodes in the network may be divided into different blockchain fragments, where one blockchain fragment corresponds to one fragment identifier, and the fragment identifier is identification information of the blockchain.

Illustratively, table 1 below is an example of a correspondence relationship between an account address of a node and identification information of a block chain. The account address 1 and the account address 2 correspond to the identifier 1 together, which indicates that the node corresponding to the account address 1 and the node corresponding to the account address 2 are both a node on the block chain corresponding to the identifier 1 (that is, the node corresponding to the account address 1 and the node corresponding to the account address 2 belong to the same block chain), and similarly, the nodes corresponding to the account address 4, the account address 5 and the account address 6 are all a node on the block chain corresponding to the identifier 3.

TABLE 1

Account address	Identification information
		Account Address 1	Identification 1
Account Address 2	Identification 1
		Account Address 3	Identification 2
Account address 4	Identification 3
		Account Address 5	Identification 3
Account Address 6	Identification 3

Assuming that the account address of the second node is account address 1, from table 1, the network control device determines that the identification information of the second blockchain is identification 1.

S112, the network control device determines whether the identification information of the second blockchain is the same as the identification information of the first blockchain.

It should be understood that the network control device may store the identification information of the first block chain in advance, and may also obtain the identification information of the first block chain. In the embodiment of the present invention, it may be determined whether the second node and the first node are in the same block chain by determining whether the identification information of the second block chain is the same as the identification information of the first block chain. In the case where the network control device determines that the second node is in the same blockchain as the first node, the network control device may instruct the first node to begin the verification process for the target transaction.

S113, under the condition that the identification information of the second blockchain is the same as the identification information of the first blockchain, the network control device sends a first transaction verification indication message to the first node.

The transaction verification indication message is used for indicating the first node to send the transaction data corresponding to the target transaction to a plurality of nodes on the first blockchain.

It should be understood that the identification information of the second blockchain is the same as the identification information of the first blockchain, which means that the second blockchain is the same blockchain as the first blockchain, that is, the second node and the first node are in the same blockchain, so that the network control device may instruct the first node to send transaction data corresponding to the target transaction to a plurality of nodes on the first blockchain (or the second blockchain, which is the first blockchain) to verify the target transaction.

Optionally, the plurality of nodes on the first blockchain may be a plurality of full nodes on the first blockchain, where a full node is used to store all contents of the transaction data corresponding to the first blockchain; and the first blockchain may further include at least one lightweight node, where the at least one lightweight node is configured to store a part of content of the transaction data corresponding to the first blockchain, and when the at least one lightweight node needs to store the entire content of the transaction data corresponding to the first blockchain, the at least one lightweight node may be obtained from all nodes adjacent to the lightweight node.

S114, the first node receives a first transaction verification indication message of the network control equipment.

In this embodiment of the present invention, after S114, the first node may send target data corresponding to the target transaction to a plurality of nodes on the first blockchain to complete a verification process of the target transaction, and further determine whether to store transaction data corresponding to the target transaction in the first blockchain (specifically, in the plurality of nodes of the first blockchain). The process specifically comprises the following steps: step A-step B.

And step A, the first node respectively sends a first verification request message to a plurality of nodes on the first block chain.

The first verification request message is used for verifying the identity of the first node and the transaction data corresponding to the target transaction.

Specifically, the first node may perform operations such as encryption, signature, timestamp addition and the like on transaction data corresponding to a target transaction in a private key manner to form a target data block, and store the target data block in a cache of the first node; the target data block is then broadcast to a plurality of nodes on the first blockchain.

And step B, the first node receives a first verification return message of each of the plurality of nodes on the first block chain.

And the first verification return message comprises a verification result of one node in the first block chain on the target transaction, wherein the verification result is verification success or verification failure.

It should be appreciated that a plurality of nodes on the first blockchain begin to authenticate the target transaction after receiving the first authentication request message described above, respectively. The verification result of each of the plurality of nodes may be different, so that after the first node receives the first verification return message of each of the plurality of nodes, that is, after receiving the verification result of each of the plurality of nodes, the first node needs to agree with the plurality of nodes in the first blockchain, that is, determine whether to bill the target data block according to the verification result of each of the plurality of nodes, and it should be understood that billing is to store the target data block in the caches of the first node and the plurality of nodes. If the first node and the plurality of nodes jointly determine that the target data block needs to be booked, the first node and the plurality of nodes store the target data block (namely, the target data corresponding to the target transaction) in their respective caches, otherwise, the target data block is discarded.

In the embodiment of the present invention, when the network control device determines that the identification information of the second blockchain is the same as the identification information of the first blockchain, the network control device may send a first transaction verification indication message to the first node, instruct the first node to start a verification process of the target transaction, and further, after the first node receives a first verification return message of each of the plurality of nodes on the first blockchain, the first node and the plurality of nodes on the first blockchain together determine whether to store the target data corresponding to the target transaction in their respective caches, because the network control device determines that the identification information of the second blockchain is the same as the identification information of the first blockchain, the network control device determines that the second blockchain is the first blockchain, and the first node does not need to repeatedly acquire the transaction data of the second blockchain from the second blockchain, and further, the processing efficiency of the transaction data can be improved.

As shown in fig. 4, in one implementation, the transaction data processing method provided by the embodiment of the present invention includes S201 to S218.

S201, the first node sends a transaction request message and the state information of the first node to the network control equipment.

S202, the network control equipment receives the transaction request message of the first node and the state information of the first node.

S203, the network control equipment determines a target MEC node with the shortest communication distance with the first node according to the position information of the first node.

S204, the network control equipment determines whether the transaction data stored in the first node is the same as the transaction data corresponding to the first blockchain or not according to the block height of the transaction data stored in the first node and the timestamp of the transaction data stored in the first node.

S205, under the condition that the transaction data stored in the first node is different from the transaction data corresponding to the first blockchain, the network control device sends a first data synchronization indication message to the first node.

S206, the first node receives a first data synchronization indication message of the network control equipment.

S207, the first node sends a first data synchronization request message to the target MEC node.

S208, the target MEC node receives a first data synchronization request message of the first node.

S209, the target MEC node sends a first data synchronization response message to the first node.

S210, the first node receives a first data synchronization response message of the target MEC node.

S211, the network control device determines the identification information of the second block chain according to the account address of the second node.

S212, the network control device determines whether the identification information of the second blockchain is the same as the identification information of the first blockchain.

It should be understood that the explanation of S201-S212 can refer to the description of S101-S112 above, and the description is omitted here.

S213, under the condition that the identification information of the second block chain is different from the identification information of the first block chain, the network control device sends an overlapping data acquisition indication message to the first node.

The overlapped data indication message is used for indicating the first node to acquire the transaction data corresponding to the second blockchain from the overlapped node, and the overlapped node is used for storing the transaction data corresponding to the first blockchain and the transaction data corresponding to the second blockchain.

It should be understood that data does not intercommunicate between different block chains. For example, if the identification information of the first blockchain is different from the identification information of the second blockchain, it is indicated that the first blockchain and the second blockchain are not the same blockchain, and the node on the first blockchain cannot directly perform data interaction with the node on the second blockchain, for example, the node on the first blockchain cannot directly obtain the transaction data corresponding to the second blockchain, and similarly, the node on the second blockchain cannot directly obtain the transaction data corresponding to the first blockchain. At this time, the network control device may instruct the first node to acquire transaction data corresponding to the second blockchain from the overlapping node. The overlapping node may be understood as a database storing transaction data corresponding to the first blockchain and transaction data corresponding to the second blockchain, from which the first node may obtain the transaction data corresponding to the second blockchain.

S214, the first node receives the overlapped data acquisition indication message of the network control equipment.

S215, the first node sends an overlapping data request message to the overlapping node.

The overlapped data request message is used for requesting to acquire the transaction data corresponding to the second blockchain.

S216, the overlapping node receives the overlapping data request message of the first node.

S217, the overlapping node sends an overlapping data response message to the first node.

Specifically, the overlapped data response message includes transaction data corresponding to the second blockchain.

S218, the first node receives the overlapping data response message of the overlapping node.

At this point, the first node acquires the transaction data corresponding to the second blockchain from the overlapping node.

It should be understood that although the first node is a node on the first blockchain and the second blockchain are not the same blockchain, the first node obtains the logical identity of the node on the second blockchain by obtaining the transaction data corresponding to the second blockchain from the overlapping node. That is, at this time, although the first node still belongs to the first blockchain, the first node may perform data interaction with the node on the second blockchain (because the first node already has transaction data corresponding to blockchain 2). For example, the first node may send target data corresponding to the target transaction to a plurality of nodes on the second blockchain to complete a verification process of the target transaction, and further determine whether to store transaction data corresponding to the target transaction in the second blockchain (specifically, in a node of the second blockchain). The process specifically comprises the following steps: step C-step D.

And step C, the first node sends second verification request messages to a plurality of nodes on the second block chain respectively.

The second verification request message is used for verifying the identity of the first node and the transaction data corresponding to the target transaction.

And step D, the first node receives a second verification return message of each of the plurality of nodes on the second block chain.

And the second verification return message comprises a verification result of a node on the second block chain to the target transaction, wherein the verification result is verification success or verification failure.

It should be understood that the process of steps C-D is the same or similar to the process of steps A-B, and will not be described herein.

In this embodiment of the present invention, when the network control device determines that the identification information of the second blockchain is not the same as the identification information of the first blockchain, the network control device may send an overlapping data acquisition instruction message to the first node, and instruct the first node to acquire, from the overlapping node, the transaction data corresponding to the second blockchain. Thus, the first node does not need to uplink to the second blockchain after downlink from the first blockchain. Furthermore, after the first node acquires the transaction data corresponding to the second blockchain from the overlapping node, because the first node has the same transaction data as the transaction data corresponding to the second blockchain at this time (i.e., the node 2 does not need to add the second blockchain, and has already had the logical identity of a node on the second blockchain), the first node can determine whether to store the target data corresponding to the target transaction in its respective cache together with the nodes on the second blockchain, thereby solving the problem of data non-intercommunication between different blockchains, enabling the first node to directly perform data interaction with the second blockchain (specifically, the nodes on the second blockchain), and improving the processing practicability of the transaction data.

In one implementation, after S212, the method for processing transaction data provided by the embodiment of the present invention further includes S301-S306.

S301, under the condition that the identification information of the second block chain is different from the identification information of the first block chain, the network control equipment sends a second data synchronization indication message to the first node.

The second data synchronization indication message is used for indicating the first node to acquire the transaction data corresponding to the second blockchain from a target node, wherein the target node is one of a plurality of nodes on the second blockchain.

In conjunction with the description of the above embodiments, it should be understood that the identification information of the second blockchain is different from the identification information of the first blockchain, which indicates that the second blockchain is a different blockchain from the first blockchain (i.e., the second node and the first node belong to different blockchains). Because the nodes on different blockchains cannot perform data interaction, the network control device can instruct the first node to join the second blockchain, that is, instruct the first node to acquire the transaction data corresponding to the second blockchain. Moreover, the first node may obtain the transaction data corresponding to the second blockchain from any one of the plurality of nodes on the second blockchain, that is, any one of the plurality of nodes on the second blockchain may be a target node in the embodiment of the present invention.

S302, the first node receives a second data synchronization indication message of the network control equipment.

The second data synchronization indication message is used to instruct the first node to acquire the transaction data corresponding to the second blockchain from a target node, where the target node is one of the nodes on the second blockchain.

S303, the first node sends a second data synchronization request message to the target node.

The second data synchronization request message is used for requesting to acquire transaction data corresponding to the second blockchain.

S304, the target node receives a second data synchronization request message of the first node.

S305, the target node sends a second data synchronization response message to the first node.

The second data synchronization response message includes transaction data corresponding to the second blockchain.

S306, the first node receives a second data synchronization response message of the target node.

It should be understood that the process of the first node obtaining the transaction data corresponding to the second blockchain from the target node (i.e., S303-S306) is the same as or similar to the process of the first node obtaining the transaction data corresponding to the first blockchain from the target MEC node (i.e., S107-S110), and the explanation of S303-S306 may refer to the description in S107-S110, which is not repeated herein.

In this way, the first node may acquire the transaction data corresponding to the second blockchain, that is, the transaction data stored by the first node and the transaction data corresponding to the second blockchain are kept synchronous, and the first node becomes a node on the second blockchain, that is, the first node completes the process from the first blockchain to the second blockchain.

Further, the first node may send target data corresponding to the target transaction to a plurality of nodes on the second blockchain to complete a verification process of the target transaction, and further determine whether to store transaction data corresponding to the target transaction in the second blockchain (specifically, in a node of the second blockchain). The specific process is the same as the above step C-step D, and is not described herein again.

In this embodiment of the present invention, when the network control device determines that the identification information of the second blockchain is not the same as the identification information of the first blockchain, the network control device may send a second data synchronization indication message to the first node, and instruct the first node to obtain, from a target node (that is, any node of a plurality of nodes on the second blockchain), transaction data corresponding to the second blockchain. That is, the first node is instructed to uplink onto the second blockchain after downlink from the first blockchain, so that the first node becomes a node on the second blockchain, and thus data interaction with other nodes on the blockchain (i.e., nodes on the second blockchain) can be completed. Furthermore, the first node can complete the verification process of the target transaction through a plurality of nodes on the second block chain together, and the problem of data non-intercommunication between different block chains is solved.

In one implementation, in a case that the identification information of the second blockchain is not the same as the identification information of the first blockchain, the network control device may further determine whether to send the second data synchronization request message to the first node according to a number of transactions between the first node and at least one node on the second blockchain within a preset time.

Specifically, the network control device may obtain the transaction number of the first node with at least one node (the at least one node includes the second node) on the second blockchain within a preset time.

If the transaction number is greater than or equal to the transaction number threshold, it indicates that the transaction between the first node and at least one node on the second blockchain is a high frequency event, and thus, the first node may be instructed to join the second blockchain, i.e., become a node on the second blockchain. Further, the network control device determines to transmit a second data synchronization request message to the first node.

If the transaction count is less than the transaction count threshold, indicating that the transaction between the first node and at least one node on the second blockchain is a low frequency event, the first node may be more suitable as a node on the first blockchain. In this way, the network control device determines to send the above-mentioned overlapping data acquisition instruction message to the first node.

In the embodiment of the present invention, the first node, the network control device, and the like may be divided into functional modules according to the above method example, for example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module.
