The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a schematic structural diagram of a system for sorting blockchain transaction information according to an embodiment of the present invention. As shown in fig. 1, the system 1 for sorting blockchain transaction information provided in this embodiment includes: a sorting node sorting cluster 4, a verification node cluster 5 and a sorting distribution Center (ODC) 3. The client cluster 2, the sorting cluster 3 and the verification node cluster 5 in the sorting system 1 are connected in pairs, and the ODC3 is respectively connected with the client cluster 2, the sorting cluster 4 and the verification node cluster 5.
As shown in fig. 1, the Client cluster 2 is a Client Group or is translated into a Client cluster, and includes a plurality of Client nodes, each Client node may be a terminal initiating a transaction, and the number of the Client nodes included in the Client cluster is not limited. The client cluster is a cluster concept abstracted by a plurality of client nodes, and the client cluster is respectively connected with the verification node cluster 5, the sorting cluster 4 and the ODC3, which can be understood that each client node in the client cluster is connected with the verification node cluster 5, the sorting cluster 4 and the ODC 3.
The cluster of verification nodes 5 is a Peer Group or translated into a Peer cluster. The verification node cluster 5 includes a plurality of verification nodes, each of which may be an abstract node deployed on a server, and each of which may be used to provide a service for packing blocks into a blockchain in blockchain technology. The verification node cluster 5 connects the ordering cluster 4, the ODC3 and the client cluster 2, respectively, and it is also understood that each verification node in the verification node cluster 5 is connected to the ordering cluster 4, the ODC3 and the client cluster 2.
In particular, the ODC3 provided in this embodiment connects the client cluster 2, the ordering cluster 4, and the verification node cluster 5, respectively. The ODC may be any electronic device with data processing, or a node disposed on the server, and is configured to provide a management function of the sorting cluster 4, provide a suitable sorting node to provide a sorting service for the transaction information when the client cluster 2 requests the transaction information to be sorted, and provide a sorting service for the block when the verification node uploads the block of the transaction information. Specifically, in the embodiment shown in fig. 1, when the client cluster 2 needs to sort the transaction information of the initiated and processed blockchain, unlike the prior art that requests the sorting cluster 4 to provide a sorting service directly, the client cluster 2 that needs a sorting service in this embodiment requests the ODC3 to sort its N transaction information. Wherein the request may be by the client cluster 2 sending a request message to the ODC 3.
After receiving the request of the client cluster 2 for ordering the transaction information, the ODC3 determines at least one most suitable target ordering node from the ordering cluster 4 according to a preset criterion to provide the requested transaction information ordering service for the client cluster 2. And when the ODC determines at least one target sorting node, notifies the client cluster 2 requesting the transaction information sorting service of the at least one target sorting node. The notification may be performed by transmitting the relevant information of the at least one target sorting node, such as the address, name, location, etc., to the client cluster 2. Subsequently, when the client cluster 2 receives the information of the at least one target sorting node transmitted by the ODC3, the requested N transaction information are transmitted to the at least one target sorting node in the sorting cluster 4.
Optionally, in this embodiment, the target sorting node is at least one sorting node with the lightest load in the sorting cluster, for example, one sorting node with the lightest load or a plurality of sorting nodes sorted according to the lightest load. Alternatively, the target ranking node is at least one ranking node in the ranking cluster that is closest to the geographic location of the client cluster, e.g., the closest ranking node or a plurality of ranking nodes that are closest in rank by distance. Specifically, the ODC3 determines at least one target ranking node determined from the ranking cluster 4 in order to select a more appropriate at least one ranking node to rank the transaction information, so as to prevent all ranking services in the prior art ranking cluster from being burdened by the master node in the ranking cluster. And the ODC3 is at least one target ranking node determined to be most suitable from the ranking cluster 4 by a preset criterion. For example, if the client cluster 4 requests ranking of N transaction messages for a client node, the ODC3 determines at least one target ranking node that is geographically closest to the client node to provide ranking services for the N transaction messages to reduce the communication overhead between the two from a physical distance. For another example, when the client cluster 4 requests to sort N transaction information, the ODC3 determines the operating states of all sorting nodes in the sorting cluster 4, and sorts the N transaction information requested at this time by using at least one node with the least processed traffic or the least loaded traffic among the sorting nodes as at least one target sorting node, so as to improve the speed and efficiency of sorting the N transaction information.
Optionally, in order to determine the information of each sorting node in the connected sorting cluster 4 to determine the target sorting node, the ODC3 in this embodiment needs to register each sorting node in the sorting cluster 4 with the ODC 3. That is, each sequencing node may register with the ODC3 by sending a registration request to the ODC 3. Causing the ODC3 to request a registration by obtaining a registration request for each sort node in the sort cluster; then according to the registration request, registering and recording the information of each sequencing node in the sequencing cluster, wherein the information of each sequencing node at least comprises: the ID of the node, the location of the node, and the processing power of the node, etc.
Subsequently, after one or more sequencing nodes in the sequencing cluster receive the N transaction information transmitted by the client cluster 2, at least one target sequencing node generates M corresponding blocks from the N transaction information received by the sequencing cluster and sequences the M blocks, and transmits the M blocks to a relevant verification node in the verification node cluster 5, so that the relevant verification node adds the M blocks to a target block chain. Meanwhile, at least one target sorting node needs to transmit description information of the M blocks to the ODC in addition to transmitting the M blocks to the relevant verification node, so that the ODC provides a sorting service of the blocks when the relevant verification node adds the M blocks to the first block chain. Specifically, at least one target sorting node may transmit only basic information of the description information of the M tiles, such as names, positions, sorting, and the like, to the ODC3, and the ODC3 may store the order of the M tiles by recording sequence numbers of the M tiles according to the description information of the M tiles. The description information described herein should at least include basic information of each of the M blocks, where the basic information includes but is not limited to hash values of the M blocks to ensure uniqueness of the M blocks, or the basic information may also include ordering of the blocks in a block chain to ensure that the verification node clusters form a consistent block chain according to the ordering. It should be noted that the operations of at least one target sorting node transmitting the description information of the M blocks to the ODC3 and transmitting the M blocks to the corresponding verification nodes in the verification node cluster 5 may be performed simultaneously or sequentially.
Finally, the respective verification node in the cluster of verification nodes 5 adds M tiles to the first blockchain according to the M tiles received from the target sorting node and the sequence numbers of the M tiles received from the ODC 3. The first blockchain herein may refer to N blockchains to which the transaction information needs to be added correspondingly, or may be a blockchain to which a corresponding verification node in any verification node cluster 5 may be added. That is, when a tile is added to the tile chain by the corresponding verification node in the verification node cluster 5 provided in the present embodiment, only the data of M tiles is obtained from the sorting cluster 4, and the sequence numbers of the M tiles are obtained from the ODC 3. In a manner of separately managing data and sequence numbers, the sorting cluster is only responsible for processing the blocks of the transaction information, the ODC is only responsible for sorting the blocks, the sorting results of the blocks are provided by the ODC for all the sorting services requested by the client cluster 2, and the sorting results of the ODC3 are used as a sorting basis when the verification node cluster 5 adds the blocks to the block chain. Thus, finally, the corresponding verification nodes in the verification node cluster 5 sequentially add the M blocks to the first block chain according to the sequence of the sequence numbers of the M blocks.
In summary, in the system for sorting blockchain transaction information provided in this embodiment, the ODC is configured to determine at least one target sorting node in the sorting cluster according to a preset standard; the at least one target sorting node is used for generating M corresponding blocks from the N transaction information of the client cluster, sorting the M blocks, transmitting the description information of the M blocks to the ODC, and transmitting the M blocks to the verification node cluster; the ODC is also used for determining the sequence numbers of the M blocks and transmitting the sequence numbers of the M blocks to the verification node cluster; the verification node cluster is used for adding the M blocks into the first block chain according to the sequence numbers of the M blocks and the M blocks. Therefore, in the system for sorting blockchain transaction information provided by this embodiment, at least one target sorting node in the sorting cluster is determined by the ODC to sort the transaction information requested by the client cluster, so that the most appropriate sorting node can be determined from the sorting cluster to perform a sorting service on the transaction information, and the efficiency of sorting blockchain transaction information is improved.
Further, in the above embodiment, since each sequencing node in the sequencing cluster 4 can provide a sequencing service for the transaction information requested by the client cluster 2, in this implementation, a distributed parallel processing manner can be adopted to provide a sequencing service for the client cluster 2 at the same time. For example, assuming that there are 3 sort nodes in the sort cluster 4, which are denoted as a node, B node and C node, when the ODC3 first receives the sort service of N transaction information requested by the client cluster 2, the ODC3 determines the a node with the smallest load at this time among the 3 sort nodes to process the N transaction information. If the ODC3 also receives the service of ordering another P transaction messages requested by the client cluster 2, it determines the node B with the lowest load from the remaining 2 ordering nodes to process the P transaction messages. Therefore, in this embodiment, the ODC3 can determine different ranking nodes to process the ranking service requested by the client cluster, and even if the traffic requested by the client cluster is large, the processing efficiency of the ranking service for the transaction information can be further improved by a distributed processing manner.
