Background technique

Currently, a transaction sender device can store transaction data in its cache and other nodes on the blockchain where the transaction sender device is located. When the transaction sender device does not belong to the blockchain, or due to some reasons (such as server failure, etc.), the transaction sender device cannot keep up with the transaction data in the blockchain. The transaction data in the chain is sent to the transaction sender device. Specifically, any node in the blockchain (referred to as a target node) can provide the transaction sender device with transaction data in the blockchain.

The deployment of MEC nodes can present the characteristics of low latency and high bandwidth of service data transmission, and can also provide users with more accurate location information services. In the embodiment of the present invention, the target MEC node determined by the network control device can reduce the delay for the first node to obtain transaction data corresponding to the first blockchain (ie, the blockchain corresponding to the target MEC node).

Based on the problems existing in the background technology, embodiments of the present invention provide a method and device for processing transaction data. A first node sends a transaction request message and state information of the first node to a network control device, and the transaction request message includes the second node. (that is, the transaction recipient device corresponding to the target transaction) account address and transaction data corresponding to the target transaction, the status 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 first node. The timestamp of the transaction data stored by the node; after the network control device receives the transaction request message of the first node and the state information of the first node, it can determine the target MEC node (that is, with the first node) according to the location information of the first node. The node with the shortest communication distance), and according to the block height of the transaction data stored by the first node and the timestamp of the transaction data stored by the first node, determine the transaction data stored by the first node and the first blockchain. Whether the transaction data corresponding to the target MEC node (that is, the blockchain corresponding to the target MEC node) is the same. Then, in the case where the transaction data stored by the first node is different from the transaction data corresponding to the first blockchain, the network control device sends a first data synchronization instruction message to the first node, and the first data is the same as the instruction message. to instruct the first node to obtain transaction data corresponding to the first blockchain from the target MEC node.

In this way, the first node can obtain transaction data corresponding to the first blockchain. In this embodiment of the present invention, the network control device may determine, based on the location information of the first node, a target MEC node that may provide the first node with transaction data corresponding to the first blockchain. Furthermore, when the first node does not update the data in time or does not belong to the first blockchain, instructing the first node to obtain the transaction data corresponding to the first blockchain from the target MEC node can reduce the need for the first node to obtain the first blockchain. The delay of transaction data corresponding to the blockchain improves the processing efficiency of transaction data.

The method and device for processing transaction data provided by the embodiments of the present invention can be applied to a wireless communication system.

For example, when the node 101 needs to initiate a transaction to the node 1031, the node 101 can send a transaction request message to the control device 102. When the control device 102 determines that the node 101 is a node in the blockchain 103, the node 101 can communicate with the node 1031 For data interaction, for example, node 101 can send transaction data to node 1031, that is, two nodes in the same blockchain can realize data exchange.

The network control device 102 can obtain the status information of the node 101 and the respective data status information of the blockchain 103 and the blockchain 105 , and determine whether the node 101 is a node in the blockchain 103 or the blockchain 105 .

It should be understood that the transaction data stored by different nodes on the same blockchain are the same.

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, the network control device 102 determines that the node 101 is a node in the blockchain 103, but the transaction recipient device (assuming the transaction recipient device is the node 1051) is a node in the blockchain 105.

It should be understood that, in this 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 . For the description of the hardware structure of the first node, reference may be made to the hardware structure of the network control device. description, which will not be described in detail here.

The transaction data processing method provided by the embodiment of the present invention is applied to an application scenario where a target transaction exists between a transaction sender device (eg, a first node) and a transaction receiver device (second node). When the first node needs to send a transaction request to the second node, the first node needs to first send a transaction request message and state information of the first node to the network control device, and the network control device determines whether the first node is the first zone A node on the 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 completely describes the transaction data processing method provided by the embodiment of the present invention from the perspective of the interaction of various devices in the communication system, so as to illustrate that the first node obtains the first blockchain from the target MEC node The process of the corresponding transaction data (that is, the first node uploading to the chain), and the process of the first node storing the transaction data corresponding to the target transaction in its cache.

As shown in FIG. 3 , the transaction data processing method provided by the embodiment of the present invention may include S101-S114.

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

The transaction request message includes the account address of the second node and transaction data corresponding to the target transaction, and the second node is the transaction receiver device corresponding to the target transaction. 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.

It should be understood that when the first node needs to initiate a target transaction to the second node (for example, the first node needs to forward a bitcoin to the second node), it needs to first send the transaction request message and the state information of the first node to the network control equipment, the network control equipment first determines the current state of the first node (that is, whether it is a node on a certain blockchain). Wherein, the account address of the second node is used to determine the identification information of the blockchain corresponding to the second node (hereinafter referred to as the second blockchain), and multiple nodes on the second blockchain can identify transactions corresponding to the target transaction. The data is subjected to transaction verification to determine whether to store the transaction data in the respective caches of multiple nodes on the second blockchain; the location information of the first node is used to determine the target MEC with the shortest communication distance with the first node node, and then the first node can obtain the transaction data corresponding to the first blockchain 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 the first node. Whether the transaction data stored by the node is the same as the transaction data corresponding to the blockchain corresponding to the target MEC (hereinafter referred to as the first blockchain).

S102. The network control device receives the transaction request message of the first node and the state information of the first node.

With reference to the description of the above embodiments, it should be understood that the transaction request message of the first node includes the account address of the second node (ie, the recipient device corresponding to the target transaction) and the transaction data corresponding to the target transaction, and the status information of the first node includes the first node. The location information of a 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 the latitude and longitude of the first node, or may be an Internet Protocol (Internet Protocol, IP) address of the first node. The block height of the transaction data stored by the first node can be understood as the number of blocks corresponding to the transaction data stored by the first node. Exemplarily, it is assumed that one block includes the transaction data of 10 transactions, and the first The block height of the transaction data stored by a node is 5 (that is, the number of blocks corresponding to the transaction data is 5), then it can be determined that the first node has stored transaction data of at least 41 transactions. The timestamp of the transaction data stored by the first node is the timestamp of the transaction data of the latest transaction stored by the first node.

S103: The network control device determines, according to the location information of the first node, the target MEC node with the shortest communication distance with the first node.

It should be understood that there are multiple nodes in the network, and each of the multiple nodes can provide transaction data for the first node. In the embodiment of the present invention, the network control device determines a node with the shortest communication distance with the first node from the plurality of nodes, 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 an 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 device determines whether the transaction data stored by the first node is the same as the transaction data corresponding to the first blockchain according to the block height of the transaction data stored by the first node and the timestamp of the transaction data stored by the first node.

Wherein, the first blockchain is the blockchain 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 obtain) the respective data status information of multiple blockchains (the data status information of a blockchain includes the block height and timestamp of the transaction data corresponding to the blockchain), the network The process for the control device to determine 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 device determines whether the block height of the transaction data stored by the first node is the same as the block height of the transaction data corresponding to the first blockchain.

Step 2: The network control device 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.

Step 3. 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 that of the first blockchain. When the timestamps of the transaction data are the same, 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. Otherwise, the network control device determines that the transaction data stored by the first node is different from the transaction data corresponding to the first blockchain.

Exemplarily, it is assumed that the block height of the transaction data stored by the first node is 4, and the timestamp of the transaction data stored by the first node is 08:00 on July 10, 2020; the transaction data corresponding to the first blockchain The block height is 5, and the timestamp of the transaction data corresponding to the first blockchain is 08:01 on July 10, 2020. The network control device determines that the transaction data stored by the first node is different from the transaction data corresponding to the first blockchain.

Understandably, all nodes on the same blockchain should store the same transaction data when working properly. In the case where 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 nodes on the first blockchain), it means that the first node is the first node. A node on the blockchain. In the case that the network control device determines that the transaction data stored by 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. In this case, the first node needs to be instructed Joining the first blockchain means instructing the first node to obtain transaction data corresponding to the first blockchain.

It should be noted that when a node (such as the first node) exits a certain blockchain (such as the first blockchain) after completing the last transaction, or due to network, server performance and other reasons, the first node fails to Complete the real-time update of the transaction data corresponding to the first blockchain, so that the network control device can determine that the first node does not really become a node on the first blockchain (it can be understood that the first node is not on the chain) , and further, the first node needs to be instructed to complete the process of on-chain (ie, join the first blockchain).

S105. In the case that the transaction data stored by the first node is different from the transaction data corresponding to the first blockchain, the network control device sends a first data synchronization instruction message to the first node.

The first data synchronization instruction message is used to instruct the first node to obtain transaction data corresponding to the first blockchain from the target MEC node.

In another implementation manner, when the transaction data stored by the first node is different from the transaction data corresponding to the first blockchain, the network control device may also instruct the target MEC node to transfer the transaction data corresponding to the first blockchain Data is sent to the first node.

S106. The first node receives the first data synchronization indication message of the network control device.

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 the block chain corresponding to the target MEC node (the target MEC node is the first block chain). a node on the chain).

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

So far, the first node can obtain the transaction data corresponding to the first blockchain, that is, the transaction data stored by the first node is synchronized with the transaction data corresponding to the first blockchain, and the first node can be used as the first blockchain. A node on the chain, that is, the first node to complete the process of on-chain.

It should be noted that, after the above S104, in the 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 can determine that the first node is one on the first blockchain. The node, that is, the first node, does not need to complete the synchronization process of the transaction data in the above S105-S110.

In the transaction data processing method provided by the embodiment of the present invention, the first node sends a transaction request message and state information of the first node to a network control device, and the transaction request message includes the second node (ie, the transaction receiver device corresponding to the target transaction). ) account address and the transaction data corresponding to the target transaction, 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 time stamp of the transaction data stored by the first node; After receiving the transaction request message of the first node and the state information of the first node, the network control device can determine the target MEC node (that is, the node with the shortest communication distance with the first node) according to the location information of the first node, and determine the target MEC node according to 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 determine the transaction data stored by the first node and the first blockchain (that is, the blockchain corresponding to the target MEC node). ) are the same transaction data.

In this way, the first node can obtain transaction data corresponding to the first blockchain. In this embodiment of the present invention, the network control device may determine, based on the location information of the first node, a target MEC node that may provide the first node with transaction data corresponding to the first blockchain. Furthermore, when the first node does not update the data in time or does not belong to the first blockchain, instructing the first node to obtain the transaction data corresponding to the first blockchain from the target MEC node can reduce the need for the first node to obtain the first blockchain. The delay of transaction data corresponding to the blockchain improves the processing efficiency of transaction data.

S111. The network control device determines the identification information of the second blockchain according to the account address of the second node.

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

With reference to the description of the above embodiments, it should be understood that after receiving the transaction request message and the state information of the first node from the first node, the network control device first determines whether the first node is the first blockchain based on the state information of the first node a node on .

The identification information of the chain.

Specifically, all nodes in the network can be divided into different blockchain shards, one blockchain shard corresponds to a shard identifier, and the shard identifier is the identifier information of the blockchain.

Exemplarily, the following Table 1 is an example of the correspondence between the account address of the node and the identification information of the blockchain. Among them, account address 1 and account address 2 jointly correspond to ID 1, indicating that the node corresponding to account address 1 and the node corresponding to account address 2 are both a node on the blockchain corresponding to ID 1 (that is, the node corresponding to account address 1 is the same as the node corresponding to account address 1). The nodes corresponding to account address 2 belong to the same blockchain). Similarly, the nodes corresponding to account address 4, account address 5, and account address 6 are all nodes on the blockchain corresponding to ID 3.

Table 1

When the network control device determines that the second node and the first node are in the same blockchain, the network control device may instruct the first node to start the verification process of the target transaction.

S113. In the case 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 instruction message to the first node.

The transaction verification verification instruction message is used to instruct the first node to send the transaction data corresponding to the target transaction to multiple nodes on the first blockchain.

Optionally, the multiple nodes on the first blockchain may be multiple full nodes on the first blockchain, wherein one full node is used to store all the transaction data corresponding to the first blockchain. In addition, the first blockchain may also include at least one lightweight node, the at least one lightweight node is used to store part of the content of the transaction data corresponding to the first blockchain, when the at least one lightweight node When the entire content of the transaction data corresponding to the first blockchain needs to be stored, it can be obtained from its adjacent full nodes.

S114. The first node receives the first transaction verification indication message of the network control device.

In this embodiment of the present invention, after S114, the first node may send target data corresponding to the target transaction to multiple nodes on the first blockchain, so as to complete the verification process of the target transaction, and then determine whether to convert the transaction corresponding to the target transaction. The data is stored in the first blockchain (specifically, in multiple nodes of the first blockchain). The process specifically includes: step A-step B.

Step A: The first node sends a first verification request message to a plurality of nodes on the first blockchain, respectively.

The first verification request message includes transaction data corresponding to the target transaction, and the first verification request message is used to verify the identity of the first node and the transaction data corresponding to the target transaction.

Step B: The first node receives the respective first verification return messages of multiple nodes on the first blockchain.

Wherein, a first verification return message includes a verification result of the target transaction performed by a node in the first blockchain, and the verification result is the verification success or the verification failure.

It should be understood that after receiving the above-mentioned first verification request message respectively, multiple nodes on the first blockchain start to verify the target transaction. The verification result of each node in the multiple nodes may be different. In this way, after the first node receives the respective first verification return messages of the multiple nodes, that is, after receiving the respective verification results of the multiple nodes, the first node It is necessary to reach a consensus with the plurality of nodes on the first blockchain, that is, according to the respective verification results of the plurality of nodes, jointly determine whether to bill the target data block. It should be understood that billing is to store the target data block. into the caches of the first node and the plurality of nodes. If the first node and the multiple nodes jointly determine that the target data block needs to be billed, the first node and the multiple nodes store the target data block (that is, the target data corresponding to the target transaction) in their respective caches , otherwise, discard the target data block.

In this 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 instruction message to the first node, indicating The first node starts the verification process of the target transaction, and further, after the first node receives the respective first verification return messages of the multiple nodes on the first blockchain, the first node shares the first verification return message with the multiple nodes on the first blockchain.

It should be understood that data between different blockchains is not interoperable. For example, if the identification information of the first blockchain is different from the identification information of the second blockchain, it means that the first blockchain and the second blockchain are not the same blockchain, and the nodes on the first blockchain are not the same. It is not possible to directly interact with the nodes on the second blockchain. For example, the nodes of the first blockchain cannot directly obtain the transaction data corresponding to the second blockchain. Similarly, the nodes on the second blockchain cannot directly Obtain transaction data corresponding to the first blockchain. At this time, the network control device may instruct the first node to obtain 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 first blockchain and the second blockchain are not the same blockchain, the first node obtains the second block by obtaining the second block from the overlapping node The transaction data corresponding to the chain has the logical identity of the node on the second blockchain. That is, at this time, although the first node still belongs to the first blockchain, the first node can exchange data with nodes on the second blockchain (because the first node already has transaction data corresponding to blockchain 2). ). For example, the first node can send the target data corresponding to the target transaction to multiple nodes on the second blockchain to complete the verification process of the target transaction, and then determine whether to store the transaction data corresponding to the target transaction in the second blockchain. (specifically in the nodes of the second blockchain). The process specifically includes: step C-step D.

In this embodiment of the present invention, when the network control device determines that the identification information of the second blockchain is different from the identification information of the first blockchain, the network control device may send an overlapping data acquisition instruction message to the first node, indicating The first node obtains transaction data corresponding to the second blockchain from the overlapping node. In this way, the first node does not need to be off-chain from the first blockchain and then on-chain to the second blockchain. Furthermore, after the first node obtains the transaction data corresponding to the second blockchain from the overlapping node, since the first node has the same transaction data as the transaction data corresponding to the second blockchain at this time (that is, node 2 does not need to If you join the second blockchain, you already have the logical identity of a node on the second blockchain). In this way, the first node can work with multiple nodes on the second blockchain to determine whether to match the target transaction. The target data is stored in its respective cache, which solves the problem of data incompatibility between different blockchains, so that the first node can directly communicate with the second blockchain (specifically, multiple nodes on the second blockchain). ) for data interaction, which can improve the practicability of transaction data processing.

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

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

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

It should be understood that the above-mentioned process of the first node acquiring the transaction data corresponding to the second blockchain from the target node (ie S303-S306) is the same as the process of acquiring the transaction data corresponding to the first blockchain by the first node from the target MEC node (that is, S303-S306). S107-S110) are the same or similar, and the explanation of S303-S306 can refer to the descriptions in the above-mentioned S107-S110, which will not be repeated here.

A node on the blockchain, that is, the first node has completed the process from the first blockchain to the second blockchain.

Further, the first node can send target data corresponding to the target transaction to multiple nodes on the second blockchain to complete the verification process of the target transaction, and then determine whether to store the transaction data corresponding to the target transaction in the second blockchain. in (specifically, in the node of the second blockchain). The specific process is the same as the above step C-step D, which is not repeated here.

That is, the first node is instructed to go off the chain from the first blockchain and then upload it to the second blockchain. In this way, the first node becomes a node on the second blockchain, and can then complete the connection with the blockchain. data interaction with other nodes on the second blockchain (ie, multiple nodes on the second blockchain). Furthermore, the first node can jointly complete the verification process of the target transaction through a plurality of nodes on the second blockchain, which solves the problem of data incompatibility between different blockchains.

In an implementation manner, in the case that the identification information of the second blockchain is different from the identification information of the first blockchain, the network control device may also, according to the first node within a preset time, connect with the second blockchain The number of transactions of at least one node on the blockchain determines whether to send a second data synchronization request message to the first node.

Specifically, the network control device may acquire the number of transactions between the first node and at least one node on the second blockchain (the at least one node includes the second node) within a preset time.

If the number of transactions is greater than or equal to the threshold of the number of transactions, it indicates that the transaction between the first node and at least one node on the second blockchain is a high-frequency event. In this way, the first node can be instructed to join the second blockchain, which is the A node on the second blockchain. Further, the network control device determines to send a second data synchronization request message to the first node.

If the number of transactions is less than the threshold of the number of transactions, it indicates that the transaction between the first node and at least one node on the second blockchain is a low-frequency event, and the first node may be more suitable as a node on the first blockchain.
