Detailed Description

Features and exemplary embodiments of various aspects of the present application will be described in detail below, and in order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings and the detailed embodiments. It should be understood that the particular embodiments described herein are meant to be illustrative of the application only and not limiting. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the application by showing examples of the application.

It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.

In order to facilitate the detailed explanation of the technical scheme of the data transmission method of the application, it is required to be explained that in the existing multi-system collaboration scene, data interaction among the systems is mostly realized by adopting a data interface mode.

As shown in fig. 1, the system architecture diagram of the government-enterprise private line opening flow generally requires hundreds of cross interfaces for implementing the construction of the collaboration architecture. When a foreground light application system (i.e., a foreground server) needs to be built in a business foreground, a plurality of data interaction interfaces need to be developed between the foreground light application system and each background business system (i.e., a background server), and due to the complexity of data interaction, the background business systems and the foreground light application systems must be mutually connected through tight interfaces in a crossing way, so single-point faults easily occur, and maintainability is reduced.

Moreover, from the aspect of the robustness of the whole collaboration framework, if any background service system temporarily leaves the service, the function of the collaboration framework is lost, and after some historical data query interfaces with higher real-time requirements temporarily leave the service, the interfaces are in an unavailable state, so that the functions are completely lost.

Thus, in order to solve the above technical problem, a concept of a technological platform is proposed, that is, integrating and packaging the capability of using cloud or other infrastructure, and the capability of applying various technological middleware. Filtering out technical details, providing a simple and consistent capability interface of an application technology infrastructure which is easy to use, and helping to quickly construct a foreground and a business center and a data center.

Based on the technical background concept, the technical middleware can be utilized to integrate public service capability, associated service data of a background service system can be directly obtained downwards, filtering and integrating capability of data and service data association relation is provided for a foreground light application system upwards, and construction of a foreground and background collaboration framework can be effectively improved.

In addition, in the scenario of multi-system collaboration as shown in fig. 1, each system only sends and receives data meeting the service needs of both parties, so that the system often discards the association relationship and change record of the self-considered useless data, and in the event of any system crash, the historical data in the system is lost, so that the traceability of the existing multi-system collaboration mode for the data is low.

At this time, the blockchain technology is taken as a decentralised distributed database, is essentially a shared database, and stores data or information therein, and has the characteristics of ' non-falsifiability ', ' whole trace ', ' traceability ', ' disclosure transparency ', collective maintenance ' and the like. Based on these features, the blockchain technique can be applied to any scene requiring traceable, tamper-proof or falsified-proof data records.

Therefore, in order to solve the technical problems of complexity of a system architecture in a multi-system cooperation scene, low data traceability in a data transmission process and the like, the embodiment of the application provides a data transmission method, a device, equipment and a computer storage medium based on characteristics of a technology in a middle station and a blockchain technology.

The data transmission method provided by the embodiment of the application is applied to a service processing system. Fig. 2 is a system configuration diagram of a service transmission system according to an embodiment of the present application. As shown in fig. 2, the service processing system includes a blockchain network, a foreground server, and N background servers, where N is an integer greater than 1.

The foreground server: typically, the front-end user oriented one or more servers, and the front-end server mainly presents and analyzes data and provides application functions of a data consumption hierarchy for users. The foreground server is characterized in that data are read and written to the blockchain node, and the read data are far larger than the written data, and even the blockchain node is output to the foreground server in a unidirectional way. The foreground server can directly read and write a Key value database (Key-value database, KV database) of the blockchain node through an application layer in the blockchain node without deploying a relational database.

Block chain network: the blockchain network comprises a plurality of blockchain nodes, and the blockchain nodes are connected with a foreground server and N background servers. In the block chain network, all block chain link points synchronize the full uplink data, the block chain link points are directly in butt joint with a foreground light application system and a background service system, meanwhile, the block chain nodes realize the interconnection of the block chain network through a Peer-to-Peer (P2P) network and bear the throughput of the foreground service data and the background service data. The block chain nodes can realize telescopic deployment according to the actual needs of the foreground server and the background server, and can finish data on-demand chaining and on-demand consumption on the basis of not damaging the original system cooperation mode; because complex cross interface development is not needed, the foreground server can directly pass through the block chain node throughput data, and in order to ensure the stability and the safety of the block chain network, the block chain node of the foreground server needs to pass through the safety certification of the node safety module when accessing the block chain network, so that the rapid deployment and the application of the foreground server can be realized.

The background server: the background server is mainly used for daily maintenance of resources and service data, is characterized in that data written into a blockchain node is far larger than read data, even single-phase output from the background server to the blockchain node is realized, and the background server is generally used for deploying a relational database for storing massive basic data. The background server can also realize data interaction through the blockchain network, and particularly when the end-to-end association of the data of the cross-background business system is required to be realized, the blockchain network can realize the capabilities of data such as repudiation, tamper resistance, traceability and the like.

In the service transmission system, N background servers are respectively connected with N block chain nodes in a block chain network in a one-to-one correspondence manner, and can upload service data generated by the background servers to the block chain nodes and finish uplink processing; the foreground server can also access the blockchain network through the blockchain node arranged on the foreground server, and read the service data of N background servers from the blockchain node.

Specifically, FIG. 3 illustrates a block chain node block diagram according to one embodiment of the present application. As shown in fig. 3, a blockchain node may include an application layer, a contract layer, an incentive layer, a consensus layer, a network layer, and a data layer.

Application layer: the system can be a read-write engine of the uplink data integrated for the block chain node and a read-write channel established with a background server. The read-write channel can be a state transfer application program interface (REpresentational STATE TRANSFER Application Program Interface, RESTful API) for realizing the data interaction between the blockchain node application layer and the background server; or the read-write channel can also be a trigger arranged in the background server and the block chain node database, and when the field value or the change occurs in the background server or the block chain node database, the trigger informs the read-write engine of the node of the change condition of the data so as to realize the interaction of the data. The application layer provides digital authentication service of the block chain link point to the block chain network, and the joining or reconnection of the trusted node is realized through digital signature verification.

Contract layer: the method can adopt the mode of automatic synchronization of all block chain link points in a block chain network to realize the visual configuration of the uplink data screening contract template, and can carry out compliance screening on the uplink data to realize the on-demand uplink of user service data.

Excitation layer: the statistics are generally used for counting the uplink data of each background server, and the statistics result can be used for providing workload evidence for the suppliers of the background servers, such as stimulating the suppliers to provide more data services in a point mode.

Consensus layer: the consensus mechanism may be implemented using a practical bayer fault tolerance mechanism (PRACTICAL BYZANTINE FAULT TOLERANCE, PBFT) or a consensus algorithm (e.g., RAFT algorithm, etc.).

Network layer: the distributed network interconnection may be implemented by using a P2P network of protocols such as Gossip (a protocol that is decentralised, fault tolerant and ensures final consistency).

Data layer: leveldb (i.e., a persistent stand-alone database of google open source) may be employed to enable the storage of blockchain data.

Based on the above-described service processing system of the present application, a data transmission method applied to the service processing system provided by the embodiment of the present application is first described below. Fig. 4 is a schematic flow chart of a data transmission method according to an embodiment of the present application. As shown in fig. 4, the method comprises the following steps:

step 401, in the case that a first background server generates first service data, the first background server transmits the first service data to a first blockchain node connected with the first background server, where the first background server is any one of the N background servers;

Step 402, the first blockchain node transmits the first service data to blockchain nodes except the first blockchain node in the plurality of blockchain nodes, and enables the blockchain network to perform uplink processing on the first service data;

In step 403, the second blockchain node transmits the first service data of the uplink to the second background server, so that the second background server performs service processing based on the first service data, where the second blockchain node is a blockchain node connected to the second background server, and the second background server is used to process a first service in the service flow, and the first service is a next service of the service processed by the first background server.

Based on the first service data, under the condition that the first background server generates the first service data, the first background server transmits the first service data to a first blockchain node connected with the first background server, and enables the blockchain network to perform uplink processing on the first service data; the second block link transmits the first service data which is uplink to the second background server, so that the second background server performs service processing based on the first service data. Therefore, the data transmission method can upload the service data generated by N background services to the corresponding blockchain nodes, and uplink all the service data through the blockchain network, so that the data loss in the server caused by the breakdown of any server can be avoided, and the traceability of the data in the collaborative service processing system is improved.

In step 401, the first background server generates first service data and transmits the first service data to a first blockchain node connected thereto.

The first background server may be any one of N background servers, and the first background server may be configured to process a service in a service flow, and generate first service data.

In addition, the first blockchain node is a blockchain node deployed in the first background server, and the first blockchain node may be used for receiving service data transmitted by the first background server and transmitting the service data to the first background server.

It should be noted that, the first background server may implement data interaction with the first block link point application layer through a RESTful API interface; or the first background server can also be a trigger deployed in a database of the first background server and the first blockchain node to realize data interaction. In addition, the manner of implementing the data interaction between the first background server and the first blockchain node may be by other manners, which are not limited herein.

Similarly, in the implementation of the present application, the manner in which the N background servers and the blockchain nodes corresponding to the N background servers implement data interaction may be the same as the manner in which the first background server and the first blockchain node implement data interaction, which is not described in detail herein.

In addition, in the embodiment of the present application, the first background server may further generate a unique identifier, where the unique identifier may be an identifier indicating a service flow, and the first background server sends the unique identifier to the first blockchain node. In the first blockchain node, the unique identification code may be used as an identifier to store the first service data.

Specifically, the first background server generates a unique identification code, and the unique identification code is used for identifying the business process;

the first background server sends the unique identification code to the first blockchain node.

Based on the unique identification code, the first background server generates the unique identification code and stores the first service data in the first blockchain node by taking the unique identification code as an identification, so that the service data in the blockchain node can be conveniently distinguished based on the unique identification code.

In step 402, the first blockchain node transmits the first service data to blockchain nodes other than the first blockchain node in the blockchain network, and causes the blockchain network to perform uplink processing on the first service data.

The plurality of block link points in the block chain network can be interconnected through a P2P protocol of a network layer in each block chain node, so that the first block chain node can transmit the first service data to all block chain nodes in the block chain network.

In addition, the block chain network performs the uplink processing on the first service data, which may be that after the first service data is checked by an administrator, the block chain network performs the uplink processing on the checked first service data; the blockchain network may perform uplink processing on the first service data if the first service data meets a preset uplink condition.

In the step 403, the second blockchain node deployed on the second background server may upload the uplink first service data to the second background server, and the second background server may perform service processing based on the first service data.

The second background server may be a server for processing a first service in the service flow, and the first service may be a next service of the services processed by the first background server in the service flow.

In addition, the second background server performs service processing based on the first service data, and may process the first service based on the acquired first service data and generate second service data.

Specifically, after the second block link transmits the first service data of the uplink to the second background server, the method further includes:

Transmitting the second service data to the second blockchain node by the second background server under the condition that the second background server generates the second service data;

the second blockchain link point transmits the second service data to blockchain nodes except the second blockchain node in the plurality of blockchain nodes, and enables the blockchain network to perform uplink processing on the second service data.

Based on the method, the second background server transmits the generated second service data to the second block chain node and performs uplink processing on the second service data by the block chain network, so that the loss of the second service data can be avoided, and the second service data can be prevented from being tampered and the like.

When the N background servers process different services in the service flow, respectively generating a plurality of different service data, and uploading the generated plurality of different service data to N corresponding blockchain nodes by the N background servers to enable the blockchain network to perform uplink processing on the service data in the N blockchain nodes. The manner in which the blockchain network performs uplink processing on the service data in the N blockchain nodes may be the same as the manner in which the blockchain network performs uplink processing on the first service data, which is not described herein.

After the blockchain network performs uplink processing on the service data in the N blockchain nodes, each of the plurality of blockchain nodes contains the service data generated by the N background servers. Therefore, the N background servers can acquire service data except the service data generated by the background servers from the corresponding block chain nodes in the service flow.

Specifically, the obtaining, by the first background server, the data in the first blockchain node may include the following steps:

uploading the generated plurality of service data to the N blockchain nodes by the N background servers respectively, and sending a first request for acquiring the service data in the first blockchain node to the first blockchain link node by the first background server under the condition that the blockchain network carries out uplink processing on the plurality of service data, wherein the data in the first blockchain node comprises the service data generated by the N background servers;

The first block link point transmits traffic data other than the first traffic data to the first background server in response to the first request.

Based on the above, the plurality of service data generated by the N background servers are subjected to uplink processing, so that the plurality of blockchain nodes comprise the plurality of service data, and then the N background servers can read the service data generated by other background servers, so that data interaction among the N background servers can be realized.

Or the first background server acquires the data in the first block chain node, or the first block chain node sends the service data to the first background server according to a preset data transmission rule. For example, the preset data transmission rule is that the first background server only can acquire the service data of the second background server, and then the service data of the second background server can be directly transmitted to the first background server when the service data of the second background server in the first blockchain node is changed.

It should be noted that, the manner in which any one of the N background servers obtains service data except the service data generated by its own background server from the corresponding block link point may be the same as the manner in which the first background server obtains the data in the first block chain node, which is not described herein.

In addition, as can be seen from the above description, the first background server may further generate a unique identifier for identifying the service flow, and transmit the unique identifier to the first blockchain node, and in the first blockchain node, the first service data may be stored with the unique identifier as an identifier.

Similarly, the first blockchain node transmits the unique identifier to blockchain nodes other than the first blockchain node in the plurality of blockchain nodes, that is, each of the plurality of blockchain nodes in the blockchain network includes the unique identifier. At this time, in the N blockchain nodes, the unique identifier may be used as an identifier, and the service data transmitted to the corresponding blockchain node by the N background servers may be stored. After the blockchain network performs uplink processing on the service data in the plurality of blockchain nodes, the unique identification code can be used as an identification to store the plurality of service data in the corresponding service flow.

the first background server sends the unique identification code to the first blockchain node;

The first blockchain node transmits the unique identification code to blockchain nodes of the plurality of blockchain nodes other than the first blockchain node to enable a plurality of business data of the plurality of blockchain nodes to correspond to the unique identification code.

Based on the method, the plurality of business data in the business process are stored in the plurality of blockchain nodes by taking the unique identification code as the identification, and the data needed in the blockchain nodes can be read based on the unique identification code, so that the method is more convenient and quick.

According to the data transmission method provided by the embodiment of the application, in the applied service processing system, after the block chain network carries out uplink processing on service data in a plurality of block chain nodes, each block chain node contains the same service data.

Therefore, the foreground server can also acquire the service data generated by the N background servers from the corresponding blockchain nodes. The manner in which the foreground server reads the service data deployed in the own blockchain node may be that the foreground server sends a service data reading request to the blockchain node deployed in the foreground server, and the blockchain node deployed in the foreground server responds to the reading request and sends the requested service data to the foreground server.

Specifically, fig. 5 shows a further flow chart of a data transmission method according to an embodiment of the present application. As shown in fig. 5, the foreground server is connected to a third blockchain node, where the third blockchain node is a node other than the N blockchain nodes in the plurality of blockchain nodes, and the method further includes the following steps:

Step 501, the foreground server sends a service data reading request to the third blockchain node, where the service data reading request carries indication information for indicating service data of the N background servers;

Step 502, the third block link point responds to the service data reading request and sends the service data indicated by the indication information to the foreground server.

Based on the method, the foreground server can access the blockchain network through the blockchain node deployed on the foreground server, and then can read data generated by N background service systems from the blockchain node, so that a data interface between the foreground server and the background server in the service processing system can be simplified, and the problem that the required data cannot be read due to the fact that the data is lost caused by the failure of the background server can be avoided.

The read request may further include a unique identifier of the service flow, and the third blockchain node may send service data to the foreground server according to the unique identifier.

In addition, before the foreground server sends the service data reading request to the third blockchain node, the third blockchain node needs to be authenticated by the blockchain node with the authentication service function in the blockchain network before the third blockchain node can be accessed to the blockchain network.

Specifically, before the foreground server sends the service data reading request to the third blockchain node, the method further includes:

the third blockchain node sends request information for requesting to access the blockchain network and a digital signature of the third blockchain node to a fourth blockchain link node, wherein the fourth blockchain node is a preset blockchain node with an authentication service function, the fourth blockchain node is any one of the N blockchain nodes, and the digital signature is used for indicating identity verification information of the third blockchain node;

and the fourth blockchain node responds to the request information, verifies the digital signature and accesses the third blockchain node to the blockchain network under the condition that the digital signature passes the verification.

Based on this, the third blockchain node sends request information requesting access to the blockchain network and a digital signature of the third blockchain node to the fourth blockchain node, and the third blockchain node is accessed to the blockchain network if the fourth blockchain node passes authentication. Therefore, the data security in the data transmission process can be improved, and the data is prevented from being acquired by the foreground server which is not in compliance with the regulations.

The fourth blockchain node may be any one of N blockchain nodes corresponding to the N background servers, a target address may be configured for the fourth blockchain node in advance, the third blockchain node may locate the fourth blockchain node based on the target address, and send request information requesting to access the blockchain network and digital signature information to the fourth blockchain node.

In addition, the verifying the digital signature by the fourth blockchain node may be that after obtaining a decryption public key corresponding to the third blockchain node, the digital signature is decrypted, and then the decrypted digital signature and the signature information of the third blockchain node that is pre-configured are compared and verified.

Specifically, the verifying the digital signature by the fourth blockchain node in response to the request information may include:

the fourth blockchain node obtains a decryption public key of the third blockchain node;

decrypting the digital signature by the fourth blockchain node based on the decryption public key;

And confirming that the digital signature passes verification under the condition that the decrypted digital signature is matched with the pre-configured signature information.

Based on the above, the digital signature is decrypted by the decryption public key corresponding to the third blockchain node, and if the decrypted digital signature and the pre-configured signature information match, the digital signature verification is confirmed to pass. Thus, the access of the foreground server which is not in accordance with the regulations to the blockchain network through the blockchain link point can be avoided.

The pre-configured signature information may be signature information of a blockchain node that is pre-configured in the blockchain network to allow access, and may be considered to allow access to a third blockchain link point when the decrypted digital signature is identical to the pre-configured signature information.

Or the above-mentioned way that the foreground server reads the service data in the blockchain node may be that the service data required by the foreground server is preset, and when the data in the blockchain node in the blockchain network is changed or the data is newly added, the blockchain node actively transmits the changed data or the newly added data meeting the preset service data required by the foreground server to the foreground server.

It should be noted that, the data transmission method provided in the embodiment of the present application may implement data interaction between N background servers and the foreground server through a blockchain node in a blockchain network, but for a service with a relatively high real-time requirement of data in a service flow, the data transmission may also be implemented by connecting N background servers through a cross interface, and at the same time, service data generated by the N background servers are uploaded to blockchain nodes deployed in the N background servers, so that the blockchain network performs uplink processing on the service data, thereby avoiding delay data transmission and data loss.

To better describe the whole scheme, fig. 6 shows a system architecture diagram of a specific application scenario of a service processing system according to an embodiment of the present application.

As shown in fig. 6, the service processing system includes a blockchain layer (i.e., a blockchain network), a government and enterprise private line opening process (i.e., N background servers), and a government and enterprise service full life cycle management platform (i.e., a foreground server). Specifically:

the special government and enterprise line opening flow (namely N background servers): the flow system consists of four background service systems (namely four background servers) which are respectively used for cooperatively cooperating with a stone-ordering system (resource pre-coverage management system), an order system, comprehensive resources and an engineering construction management system (ENGINEERING CONSTRUCTION MANAGEMENT SYSTEM, ECMS) to finish closed-loop management of dozens of links such as resource coverage pre-investigation, order initiation, engineering construction, integrated quick opening and the like of government enterprise service points.

Blockchain layer (i.e., blockchain network): the block chain nodes (namely N block chain nodes in the block chain network) can be respectively deployed on four background service systems and the government enterprise service full life cycle management platform (namely a foreground server), the four background service systems can push end-to-end associated data required by the government enterprise service full life cycle management platform to the block chain nodes to be subjected to compliance checking and then to be uplink, and the four background service systems are synchronized through the block chain P2P network full life cycle management platform, and all the block chain nodes respectively store full data (namely service data generated by the four background servers).

Government enterprise business full life cycle management platform (i.e. foreground server): the system can directly collect the data required by the block data in the block chain node (third block chain node) deployed on the system server, and transmit the data to the service upper layer application to realize the functions of end-to-end ring node monitoring, link related data transverse and longitudinal analysis and the like of the opening flow of the special line of the government enterprise.

For the service processing system in the specific application scenario shown in fig. 6, fig. 7 is a schematic flow chart of the specific application scenario of the data transmission method according to an embodiment of the present application.

As shown in fig. 7, the method specifically comprises the following steps:

In step 701, the four background service systems transmit the generated service data to the corresponding blockchain nodes.

For example, (1) a point stone forming (i.e. a first background server) determines, through a resource pre-coverage survey function, that a group user named "K11 shopping art center" points as sample information (i.e. first business data):

group user point name: k11 shopping art center

Standard address: shenyang city and flat urban area exposition road 2A 1 Shenyang K11 shopping art center A seat 1 unit 1 building 1

Coordinates: 123.43776905303956 41.75073121248109

Resource coverage status: thick cover

Simultaneously generating a unique identification code (Universally Unique Identifier, UUID) for said information:

UUID：96b5affb-df8b-4936-9a34-17a2ef064bcc

The data is uniquely identified by a UUID to form a record that is stored in the blockchain node (i.e., the first blockchain node).

(2) According to the opening flow definition of the special line of the government and enterprise, the order system (namely the second background server) receives data generated by the stone-ordering and money-making through an interface and generates the following sample information (namely the second service data):

Special line type: data special line

Dedicated line bandwidth: 100M of

The access mode is as follows: packet transport network (Packet Transport Network, PTN)

The data are expressed in UUID:96b5affb-df8b-4936-9a34-17a2ef064bcc is a unique identifier (i.e., unique identification code) that forms a record that is stored in the data block of the blockchain node.

(3) According to the opening flow definition of the special line of the government and enterprise, the comprehensive resource system receives the data pushed by the order system through the interface, and generates the following sample information:

Opening a scheduling list number: 10006286

Charging number: 890058620899

The data takes UUID 96b5affb-df8b-4936-9a34-17a2ef064bcc as unique identification to form a record which is stored in a data block of the blockchain node

(4) If the point location is judged to be "no coverage" by the point stone diagenesis (resource pre-coverage management system), the ECMS receives data pushed by the point stone diagenesis through an interface according to the opening flow definition of the special line of the government and enterprise, and the following sample information is generated:

single engineering identity number (Identity Document, ID): 40023986280

Single engineering completion time: 2020-5-18

The data are expressed as UUID:96b5affb-df8b-4936-9a34-17a2ef064bcc

For unique identification, a record is formed for storage in the data block of the blockchain node.

In step 702, the blockchain network performs uplink processing on traffic data on four blockchain nodes.

Specifically, blockchain nodes deployed on four background business systems synchronize blockchain node data throughout the network.

In step 703, the blockchain node (i.e., the third blockchain node) of the foreground light application (i.e., the foreground server) requests access to the blockchain network from the node with authentication service function (i.e., the fourth blockchain node).

Specifically, the blockchain node deployed on the government enterprise business full life cycle management platform sends a digital signature (encrypted by a private key thereof) and an access blockchain network request to the node with the authentication service function by configuring a target IP address (target address).

Typically, a node with authentication service function (i.e. a fourth blockchain node) is deployed on a service system (i.e. a first background server) generating a unique identifier of data, and is deployed on a stone-ordering system.

Step 704, the node with authentication service function authenticates the access request using a digital signature mechanism.

Specifically, the blockchain node on the deployment point stone system decrypts and verifies the digital signature by the public key of the blockchain node deployed on the government enterprise business full life cycle management platform.

Step 705, if the authentication fails, refusing the foreground light application block link point access request. Specifically, the blockchain node on the deployment point stone system refuses the blockchain network access request of the blockchain node deployed on the government enterprise business full life cycle management platform.

If the verification is successful, the blockchain point of the foreground light application system accesses the blockchain network through the P2P protocol in step 706.

Specifically, a blockchain node on a government enterprise business full life cycle management platform accesses a blockchain network through a P2P protocol.

In step 707, the blockchain node (i.e., the third blockchain node) of the foreground light application synchronizes the full amount of data that is uplink.

Specifically: the block chain nodes on the government enterprise business full life cycle management platform synchronize full volume block data through the block chain network.

In step 708, the foreground light application system reads data from the data blocks of the blockchain node as needed (i.e., traffic data required by the foreground server is preset).

Specifically: and the government enterprise business full life cycle management platform reads and writes required data from the block link points according to business requirements.

For example, presenting a standard eleven-level address for the group user roll call K11 shopping mall, line bandwidth, billing number, and single project completion time, may be accomplished by a UUID attached to the K11 shopping mall: 96b5affb-df8b-4936-9a34-17a2ef064bcc, the acquisition data is as follows:

group user point name: k11 shopping art center

UUID：96b5affb-df8b-4936-9a34-17a2ef064bcc

Dedicated line bandwidth: 100M of

Charging number: 890058620899

Single engineering completion time: 2020-5-18

The data is presented through page formatting of the government enterprise business full life cycle management platform, and related data can be extracted through UUID (i.e. unique identification code) according to any one field or a plurality of fields to carry out data change and multidimensional analysis of a plurality of records.

For another example, when the user needs to enter data in the government enterprise business full life cycle management platform and transfer the data to the point stone diagenetic system, the group user point name is as follows: the point location of the K11 shopping art center is added with the current state value, and the state value can be calculated by: the renewed charge is attached to the UUID (i.e., unique identification code): 96b5affb-df8b-4936-9a34-17a2ef064bcc and stores the record to the data block by means of an application program interface (Application Program Interface, API) or by direct reading and writing of KV databases. After the block chain link point network is synchronized, the block chain nodes integrated by the stone-pointing and gold-forming system monitor that the block data are changed, find out the data record, and store the extracted state value into a relational database. (i.e., the traffic data of the first blockchain node is changed, the changed traffic data is actively transmitted to the first background server).

For another example, when a user needs to count a single project with PTN access that has been completed between 5 months and 6 months in 2019 on a government enterprise business full lifecycle management platform (i.e., a foreground server). Firstly, screening out a finished single project from 5 months to 6 months in 2019 from block data in a third block chain node; and then extracting UUIDs of all the screened single projects. And finally, searching all the data with PTN access modes through the extracted UUID.
