Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings, and furthermore, embodiments of the present invention and features in the embodiments may be combined with each other without conflict.
Example 1
Fig. 1 is a flowchart of a blockchain data uplink method provided in an embodiment of the present invention, where the embodiment is applicable to a case of uplink storage of transaction data in a blockchain system, the method may be applied to a blockchain data uplink system, and the blockchain data uplink system may include: at least one client, one gateway, and at least one blockchain cluster.
FIG. 2 is a schematic diagram of a blockchain data chaining system according to an embodiment of the present invention. As shown in fig. 2, the blockchain data chaining system includes a plurality of clients, a gateway, and three blockchain clusters: cluster 1, cluster 2 and cluster 3 each include a number of blockchain nodes.
As shown in fig. 1, the method specifically includes the following steps:
and 110, the client generates a transaction identification code according to the transaction data, generates a transaction data packet according to the transaction identification code and the transaction data, and sends the transaction data packet to the gateway.
The transaction identification code may carry routing information for uplink of transaction data.
Specifically, when a transaction occurs, the client may generate a transaction identifier corresponding to the transaction data according to a preset transaction identifier generation rule. In the generated transaction identification code, the routing information of the transaction data to be transmitted can be hidden in the generated transaction identification code for the transmission operation of the transaction data. As shown in fig. 2, a transaction ID generator may be provided in the client, which may be used to generate a transaction identification code when a transaction occurs. After the transaction identification code is generated, the transaction data can be marked to form a transaction data packet, and the client sends the transaction data packet to the gateway.
Alternatively, the transaction identification code may include a first number of digits routing information and a second number of digits transaction random numbers.
Specifically, the generated transaction identifier may be a code with a preset fixed length, and when the transaction identifier is generated, the first number of encoding positions before the transaction identifier is used for recording the route information for transmitting the transaction data, and the second number of encoding positions after the first number of encoding positions before the transaction identifier is used for storing the transaction random number.
Further, the routing information may include a third number of bit blockchain cluster identification code and a fourth number of bit ledger identification code.
In this embodiment, the encoding mode of the routing information may be further set, and the first number of bit routing information may be subdivided into a third number of bit blockchain cluster identifier and a fourth number of bit ledger identifier. It is understood that the sum of the third number and the fourth number is the first number.
Fig. 3 is a schematic diagram of a transaction identifier in a blockchain data chaining system according to an embodiment of the present invention. As shown in fig. 3, the transaction identification code may include 96 bits, the first 32 bits may record routing information, and the last 64 bits may store a transaction random number; the first 32 bits may be divided into two parts, namely, the blockchain cluster identification code of the first 16 bits, i.e., the blockchain ID in fig. 3, and the ledger identification code of the second 16 bits, i.e., the ledger ID in fig. 3.
Accordingly, step 110 may be specifically implemented by the following steps: the client determines the service type of the transaction data, determines the route information corresponding to the transaction data by combining the transaction route mapping table, generates a transaction random number, and generates a transaction identification code according to the route information and the transaction random number.
The transaction routing mapping table may include a mapping relationship between a pre-stored service type and pre-stored routing information.
Specifically, the client needs to maintain a mapping Map of pre-stored service types and pre-stored routing information, that is, a transaction routing mapping table, where routing addresses corresponding to different service types are recorded in the transaction routing mapping table. For example, different service types may have different service IDs, the routing information may be expressed as a blockchain id+ledger ID, and the mapping relationship between the service ID and the blockchain id+ledger ID may be recorded in the transaction routing mapping table. When the transaction occurs, the client can search corresponding pre-stored route information in the transaction route mapping table according to the service type of the transaction data, and determine the searched pre-stored reason information as the reason information of the current transaction data uplink. Meanwhile, the client can also generate a transaction random code with a certain number of bits, and the routing information and the transaction random code can form a complete transaction identification code.
Optionally, after the client generates the transaction identification code according to the transaction data, the method may further include: the client encrypts the transaction identification code.
Specifically, in order to perform secure transmission on information, after the transaction identification code is generated, the client may encrypt the transaction identification code according to a preset encoding encryption rule, so as to improve the security of information transmission.
Step 120, the gateway receives the transaction data packet, extracts the routing information from the transaction identification code, and sends the transaction data packet to the corresponding blockchain cluster based on the routing information for data storage.
Optionally, if the client encrypts the transaction identifier, after the gateway receives the transaction data packet, the method may further include: the gateway decrypts the transaction identification code.
In practical application, for safe transmission of information, the transmitted data is generally encrypted, and the transaction identification code also belongs to a part of the transmitted data, so if the transaction identification code received by the gateway is encrypted, the gateway needs to decrypt the encrypted transaction identification code to obtain the decrypted transaction identification code, so that the information in the transaction identification code can be conveniently analyzed.
Specifically, when the gateway receives the transaction data packet, the transaction identification code of the transaction data packet can be obtained, and the routing information in the transaction identification code can be extracted from the transaction identification code. The gateway forwards the transaction data packet to the blockchain node in the corresponding blockchain cluster according to the routing information, and the blockchain node which receives the transaction data packet stores the transaction data in an uplink manner.
Optionally, extracting the routing information from the transaction identification code may include: the first number of digits in the transaction identification code is identified as routing information.
In this embodiment, the client uses the first number of encoding positions of the transaction identifier to record the routing information for transmitting the transaction data, so that the gateway can extract the first number of bit identifier codes from the transaction identifier, and determine the extracted identifier information as the routing information.
Optionally, sending the transaction data packet to the corresponding blockchain cluster for data storage based on the routing information may include: the gateway determines a target block chain link point and a target port in the block chain cluster corresponding to the routing information according to the routing information and combining a routing node mapping table; the gateway sends the transaction data packet to the destination port of the destination blockchain node.
The routing node mapping table comprises a mapping relation between pre-stored routing information and pre-stored node port information, wherein the pre-stored node port information comprises a pre-stored block link point identification code and a pre-stored port identification code.
Specifically, the gateway needs to maintain a Map of pre-stored route information and pre-stored node port information, that is, a route node mapping table, where node port information corresponding to different route information is recorded in the route node mapping table, where the node port information may include a block link point identifier code and a port identifier code. For example, the routing information may be represented as a blockchain id+ledger ID, the node port information may be represented as a node ip+port ID, and the mapping relationship between the blockchain id+ledger ID and the node ip+port ID may be described in the routing node mapping table. When the gateway receives the transaction data packet and extracts the routing information, the gateway can search the corresponding pre-stored node port information in the routing node mapping table according to the routing information, determine the pre-stored block link point identification code and the pre-stored port identification code in the pre-stored node port information as the block link point identification code and the port identification code which need to receive the transaction data packet, and forward the transaction data packet according to the determined block chain node identification code and the port identification code thereof, wherein the block chain node corresponding to the block chain node identification code receives the transaction data packet and stores the uplink of the transaction data.
According to the technical scheme, a transaction identification code is generated according to transaction data through a client, a transaction data packet is generated according to the transaction identification code and the transaction data and is sent to a gateway, wherein the transaction identification code carries routing information of a transaction data uplink, the gateway receives the transaction data packet, extracts the routing information from the transaction identification code, and sends the transaction data packet to a corresponding blockchain cluster based on the routing information for data storage. The embodiment of the invention reduces the problem of high IO pressure of the gateway network when high-frequency transaction occurs, and conceals the routing information in the identification code of the transaction data packet when transaction data is uplink, thereby reducing the information quantity sent by a client to the gateway and improving the efficiency of data transmission and processing.
