[0026] During the process of blockchain message transmission, after the sending node of the message sends out the message, the receiving node of the message is used to receive the message. However, since the transmission distance between the receiving node and the sending node, such as the physical distance, may be relatively long, it is not possible for the sending node to directly transmit the message to the receiving node. In related technologies, one implementation method is to build a physical transmission line between the sending node and the receiving node, but this method has problems such as resource waste, high transmission complexity, and great implementation difficulty; another implementation method is to transmit the message layer by layer through the relay nodes in the pre-set routing table until the message is transmitted to the receiving node of the message. However, in this method, when a relay node fails, the blockchain cannot perceive it in time, resulting in the failure of message transmission and poor stability of blockchain information transmission.

[0027] Based on the technical problems existing in related technologies, the embodiments of the present application detect the active node list and subscribers of the sending node, determine the target active node based on the subscribers in the active node list, and further transmit the information to be sent to the receiving node through the target active node, reducing the probability of transmission failure of the message to be sent, and thus improving the stability and transmission efficiency of blockchain message transmission.

[0028] First, the application scenarios of the embodiments of the present application will be described in detail below.

[0029] An applicable scenario of the message transmission method, device, equipment, storage medium, and program product provided by the embodiments of the present application can be a message transmission scenario where the transmission distance between the sending node and the receiving node in the blockchain network is relatively long.

[0030] It can be understood that the above is only an applicable application scenario of the embodiments of the present application, and the embodiments of the present application do not limit the specific application scenario, which can be determined according to the actual application requirements.

[0031] Figure 1 It is a schematic structural diagram of the message transmission system provided by the embodiments of the present application. As Figure 1 shown, this message transmission is deployed on each node in the blockchain system, and this node includes: a sending node and an active node;

[0032] Among them, the sending node is used to implement the message transmission method provided by the embodiments of the present application;

[0033] The active node is used to obtain the message to be sent from the message pool corresponding to the sending node, and when the active node is not the receiving node in the blockchain, it acts as a new sending node to implement the message transmission method provided by the embodiments of the present application.

[0034] It can be understood that when the active node is the receiving node, after obtaining the message to be sent, there is no need to transmit the message to be sent to other nodes in the blockchain.

[0035] Exemplarily, each node in the blockchain system is consensusized with a preset routing policy.

[0036] In a possible implementation, the preset routing policy is used as a transaction and consensusized on each node in the blockchain.

[0037] Exemplarily, the preset routing policy may be: at least one active node within the preset range of the sending node can detect the messages in the message pool of the sending node itself. Specifically, on the one hand, when it is detected that the sending node involves a subscriber and the identifier of the subscriber corresponds to the identifier of the active node A among at least one active node, the active node A obtains the current message to be sent from the message pool of the sending node itself. After the active node A obtains the current message to be sent, it determines whether the receiving node of the current message to be sent is the active node A itself. If so, it determines that the transmission of the current message to be sent is completed. If not, the active node A is used as the new sending node and the transmission of the current message to be sent continues; on the other hand, when it is detected that the sending node does not involve a subscriber, after a preset duration, the active node B closest to the sending node is selected from at least one active node within the preset range. The active node B obtains the current message to be sent from the message pool of the sending node itself. After the active node B obtains the current message to be sent, it determines whether the receiving node of the current message to be sent is the active node B itself. If so, it determines that the transmission of the current message to be sent is completed. If not, the active node B is used as the new sending node and the transmission of the current message to be sent continues.

[0038] Exemplarily, the number of active nodes in the blockchain in the embodiments of the present application is not limited and can be determined according to actual application requirements.

[0039] It can be understood that by consensusizing the preset routing policy as a transaction on each node in the blockchain in the embodiments of the present application, the complexity of blockchain message transmission can be reduced.

[0040] The message transmission method provided by the present application aims to solve the above technical problems in the prior art.

[0041] The following takes the sending node shown above Figure 1 as the execution subject, and combines specific embodiments to elaborate in detail on the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0042] Figure 2 is a flowchart of the message transmission method provided by the embodiments of the present application Figure 1. For example, Figure 2 As shown, the specific implementation of the message transmission method may include the following steps:

[0043] S201. In response to a message to be sent from a first sending node in the blockchain, obtain a list of active nodes of the first sending node.

[0044] Exemplarily, the message to be sent may be a message that the first sending node currently needs to forward.

[0045] Exemplarily, the message to be sent may be stored in the message pool of the first sending node itself.

[0046] Exemplarily, the list of active nodes may include at least one active node.

[0047] Exemplarily, an active node may be a node in the blockchain that is currently in an idle state and not in a fault state within a preset range of the first sending node.

[0048] Exemplarily, the preset range may be determined based on a preset routing policy, which is similar to the above and will not be elaborated here.

[0049] S202. Detect whether the first sending node involves subscribers.

[0050] In a possible implementation, obtain subscriber information of the first sending node in the blockchain, and based on the subscriber information, detect whether the first sending node involves subscribers.

[0051] Exemplarily, the subscriber information may include at least one subscriber and an identifier corresponding to each subscriber.

[0052] In a possible implementation, the subscribers of the first sending node are determined as follows: obtain the transaction tag of the first sending node, and based on the preset routing policy, among the nodes within the preset range, determine the nodes that contain the transaction tag of the first sending node as subscribers. That is, at least one transaction tag in the transaction tags of the subscribers is the same as the transaction tag of the first sending node.

[0053] Exemplarily, the transaction tag of the first sending node may be a transaction tag corresponding to the current message to be sent by the first sending node.

[0054] Exemplarily, each node in the blockchain may correspond to at least one transaction tag. In the message transmission method provided in the embodiments of the present application, the number of transaction tags that each node in the blockchain may correspond to is not limited, and it may be determined specifically according to actual application requirements.

[0055] The preset routing policy is similar to the above and will not be elaborated here.

[0056] S203. If it is involved, based on the subscriber and the active node list, determine the target active node, so that the target active node obtains the message to be sent from the message pool corresponding to the first sending node, and transmits the message to be sent to the receiving node in the blockchain.

[0057] Exemplarily, the number of subscribers detected for the first sending node can be one or multiple.

[0058] In this step, in one possible implementation, determine the target active node according to the identifier of the subscriber and the identifier corresponding to each active node in the active node list.

[0059] Exemplarily, the target active node can be the receiving node of the message to be sent, or can be a relay node for transmitting the message to be sent.

[0060] In the embodiment of the present application, in response to the message to be sent of the first sending node in the blockchain, by obtaining the active node list of the first sending node, detect whether the first sending node is involved in subscribers, and when it is involved, based on the subscribers and the active node list, determine the target active node, so that the target active node obtains the message to be sent from the message pool corresponding to the first sending node, and transmits the message to be sent to the receiving node in the blockchain. In the embodiment of the present application, by determining the target active node based on the active node list and subscribers of the first sending node, and transmitting the message to be sent to the receiving node through the target active node, the probability of transmission failure of the message to be sent is reduced, and the stability and transmission efficiency of blockchain message transmission are improved.

[0061] It can be understood that in the message transmission method provided by the embodiment of the present application, there is no need to build a physical transmission line between the receiving node and the sending node, which realizes resource overhead savings and can also realize long-distance message transmission.

[0062] When the active node list includes at least one active node, optionally, the message transmission method provided by the embodiment of the present application further includes: if it is not involved, after a preset duration, calculate the distance between each active node in the at least one active node and the first sending node; determine the active node with the smallest distance from the first sending node as the target active node.

[0063] Exemplarily, when it is detected that the first sending node is not involved in subscribers, after a preset duration, calculate the distance between each active node in the active node list and the first sending node, and determine the active node with the smallest distance from the first sending node as the target active node.

[0064] Exemplarily, the distance between each active node and the first sending node can be measured by the number of network hops or broadband consumption, or by network latency, or by the physical distance between nodes. In the message transmission method provided in the embodiments of the present application, the measurement method of the distance between nodes is not limited, and can be specifically determined according to actual application requirements.

[0065] Exemplarily, the embodiments of the present application do not limit the size of the preset duration, and can be specifically determined according to actual application requirements.

[0066] Optionally, in the message transmission method provided in the embodiments of the present application, if it is detected that the first sending node is involved with a subscriber within the preset duration, the target active node can be determined according to the latest detected subscriber and the active node list.

[0067] It can be understood that by determining the active node with the smallest distance from the first sending node as the target active node, the message transmission efficiency and reliability can be improved. At the same time, the network bandwidth occupied during the message transmission process can be reduced, thereby reducing the network load.

[0068] The following combines Figure 3 to detail the specific implementation manner of determining the target active node according to the subscriber and the active node list in step S203.

[0069] Figure 3 is the flow diagram of the message transmission method provided in the embodiments of the present application Figure 2 As Figure 3 shown, the specific implementation manner of determining the target active node according to the subscriber and the active node list may include the following steps:

[0070] S301, for each active node among at least one active node, determine whether the identifier of the active node is the same as the identifier of the subscriber.

[0071] Exemplarily, each node in the blockchain system is configured with a corresponding node identifier.

[0072] Exemplarily, when the identifier of the active node is the same as the identifier of the subscriber, it indicates that the active node is a subscriber of the first sending node.

[0073] In this step, determine whether the identifier of the active node is the same as the identifier of the subscriber. If they are the same, execute step S302; if they are not the same, execute step S303.

[0074] S302, determine that the active node is the target active node.

[0075] S303, after the preset duration, determine the active node with the smallest distance from the first sending node as the target active node.

[0076] The specific implementation method is similar to the above, and will not be elaborated here.

[0077] In the embodiment of the present application, for each active node among at least one active node, by determining whether the identifier of the active node is the same as the identifier of the subscriber, and when they are the same, determining the active node as the target active node, and when they are different, after a preset time period, determining the active node with the smallest distance from the first sending node as the target active node, and transmitting the message to be sent through the target active node, which improves the message transmission efficiency, stability and reliability. At the same time, the network bandwidth occupied during the message transmission process can be reduced, thereby reducing the network load.

[0078] Optionally, in the message transmission method provided by the embodiment of the present application, when it is detected that the subscribers involved by the first sending node are at least two subscribers, a possible implementation manner for determining the target active node according to the subscriber and the active node list may be: for each active node in the active node list, determining whether the identifier of the active node is the same as the identifier of each of the at least two subscribers, if there is a subscriber whose identifier is the same as the identifier of the active node, determining the active node as the target active node; if not, after a preset time period, determining the active node with the smallest distance from the first sending node as the target active node.

[0079] Optionally, when there are at least two active nodes whose identifiers are the same as the identifiers of the corresponding subscribers respectively, the distances between the at least two active nodes and the first sending node are further determined, and the active node with the smallest distance from the first sending node is determined as the target active node.

[0080] Optionally, in the message transmission method provided by the embodiment of the present application, a possible implementation manner for the target active node to transmit the message to be sent to the receiving node in the blockchain may be: determining whether the target active node is the receiving node; if so, determining that the message to be sent is completely transmitted; if not, determining the target active node as the second sending node, and transmitting the message to be sent through the second sending node.

[0081] Exemplarily, the identifier of the receiving node may be carried in the message to be sent.

[0082] In a possible implementation manner of determining whether the target active node is the receiving node, it may be determined whether the identifier of the target active node is the same as the identifier of the receiving node carried in the message to be sent. If they are the same, it is determined that the target active node is the receiving node. If they are different, it is determined that the target active node is not the receiving node.

[0083] Exemplarily, the specific implementation manner of transmitting the message to be sent by the second sending node may be: obtaining the list of active nodes of the second sending node, detecting whether the second sending node involves subscribers, and when it does, determining the target active node according to the subscribers and the list of active nodes, enabling the target active node to obtain the message to be sent from the message pool corresponding to the second sending node, and transmitting the message to be sent to the receiving node in the blockchain, and so on, until the message to be sent is transmitted to the receiving node.

[0084] In the embodiment of the present application, by determining whether the target active node is the receiving node, and when the target active node is the receiving node, determining that the message to be sent is successfully transmitted, and when the target active node is not the receiving node, determining that the target active node is the second sending node, and transmitting the message to be sent through the second sending node. In the embodiment of the present application, by transmitting the message to be sent to the receiving node based on one or more target active nodes, the probability of transmission failure of the message to be sent can be reduced, thereby improving the stability and transmission efficiency of blockchain message transmission.

[0085] Optionally, in the message transmission method provided by the embodiment of the present application, the list of active nodes is obtained in the following manner: detecting the active nodes of the first sending node based on a preset routing policy to obtain the list of active nodes.

[0086] Exemplarily, the preset routing policy is similar to the above, and will not be elaborated here.

[0087] Exemplarily, a possible implementation manner of detecting the active nodes of the first sending node may be: detecting the active nodes of the first sending node based on a heartbeat mechanism and / or a node discovery protocol, etc.

[0088] The embodiment of the present application does not limit the specific implementation manner of detecting the active nodes of the first sending node, and it can be determined specifically according to actual application requirements.

[0089] Exemplarily, the set composed of the detected active nodes of the first sending node is determined as the list of active nodes.

[0090] In the embodiment of the present application, by detecting the active nodes of the first sending node based on a preset routing policy to obtain the list of active nodes, it is ensured that the intermediate nodes used for transmitting the message to be sent are currently available nodes.

[0091] Optionally, the message transmission method provided by the embodiment of the present application further includes: responding to the target active node obtaining the message to be sent, and destroying the message to be sent in the message pool corresponding to the first sending node.

[0092] It can be understood that after the first sending node detects that the target active node obtains the message to be sent from the message pool of the first sending node, the message to be sent is destroyed from its own message pool, which can release the storage space of the first sending node, reduce the storage cost. At the same time, by promptly clearing the processed messages and reducing the redundant messages in the message pool, the message processing efficiency of the blockchain system can be improved.

[0093] In some embodiments, the specific implementation of the message transmission method provided by the embodiments of the present application may include the following steps:

[0094] S1, in response to the first sending node placing the message to be sent in its own message pool, based on a preset routing policy, detect the active nodes of the first sending node within a preset range to obtain a list of active nodes;

[0095] S2, detect whether the first sending node involves subscribers.

[0096] In this step, if it is detected that the first sending node involves subscribers, then execute step S3; if it is detected that the first sending node does not involve subscribers, then execute step S4.

[0097] S3, for each active node in the list of active nodes, determine whether the identifier of the active node is the same as the identifier of the subscriber, and when they are the same, determine the corresponding active node as the target active node; when they are different, after a preset duration, determine the active node with the smallest distance from the first sending node as the target active node.

[0098] S4, after a preset duration, calculate the distance between each active node in the list of active nodes and the first sending node, and determine the active node with the smallest distance from the first sending node as the target active node.

[0099] S5, the target active node obtains the message to be sent from the message pool of the first sending node. Further, the target active node determines whether it is the receiving node through the receiving node identifier carried in the message to be sent. If so, the transmission of the message to be sent is completed. If not, the target active node is used as the second sending node, and continue to execute the message transmission method provided by the embodiments of the present application until the message to be sent is transmitted to the receiving node.

[0100] In summary, the message transmission method provided by the embodiments of the present application has the following beneficial effects:

[0101] 1) By determining the target active node based on the list of active nodes of the first sending node and the subscribers, and transmitting the message to be sent to the receiving node through the target active node, the probability of the transmission failure of the message to be sent is reduced, and the stability and transmission efficiency of the blockchain message transmission are improved;

[0102] 2) There is no need to build a physical transmission line between the receiving node and the sending node, which can save resource overhead and can also achieve long-distance message transmission;

[0103] 3) By making a preset routing policy consensus as a transaction on each node in the blockchain, the complexity of blockchain message transmission can be reduced.

[0104] The following is the device embodiment of the present application, which can be used to execute the method embodiment of the present application.

[0108] The determination module 430 is used to, when the first sending node involves subscribers, determine the target active node according to the subscribers and the list of active nodes, so that the target active node acquires the message to be sent from the message pool corresponding to the first sending node and transmits the message to be sent to the receiving node in the blockchain.

[0109] In a possible implementation manner, the determination module 430 is further used to: when the first sending node does not involve subscribers, after a preset duration, calculate the distance between each active node in at least one active node and the first sending node; determine the active node with the smallest distance from the first sending node as the target active node.

[0111] In a possible implementation manner, the determination module 430 is further used to: determine whether the target active node is the receiving node; if so, determine that the message to be sent is completely transmitted; if not, determine the target active node as the second sending node and transmit the message to be sent through the second sending node.
