The present embodiment and the following embodiments will take a data update device based on a blockchain consensus mechanism as an example to illustrate the data update method of the present invention.
It can be appreciated that the method of the present embodiment may be applied to a system including a supply chain node and a federation chain platform, and a set of supply chain systems for universal terminal sales may be constructed by a blockchain system, and key data items are encrypted by a core consensus algorithm and then are uplink on a Blockchain Service Network (BSN), where each subsystem decrypts and restores by each private key based on the BSN. The detailed architecture of the universal terminal sales hierarchy based on BSN federation chains can be referred to fig. 3. The data information in the three subsystems can be circulated in a supply chain platform sold by the universal terminal by using the consensus mechanism algorithm in the embodiment, and the local storage of desensitized data is supported, and the data of any subsystem can be stored and forwarded by nodes after the data of the other two subsystems are sent out and are required to pass through in a consistent mode.
It is worth to be noted that, in the general terminal sales supply chain system in this embodiment, state flows of purchasing, supplying, sales binding, warehousing and ex-warehouse, settlement and the like can also support clients such as APP, weChat applet, PC and the like to implement and view, prompt can be performed during data update, and alarm can be performed during data and system abnormality.
For ease of understanding, the description is given with reference to fig. 4, but the present solution is not limited thereto. Fig. 4 is a functional block diagram of a system according to a first embodiment of the present invention. The system in this embodiment may include a vendor subsystem, a universal terminal subsystem, and a channel subsystem. The modules in the system comprehensively share information such as general terminal basic information, order information, serial number/SN number information, account information, payment settlement information, invoice bill information, checking data and the like through a blockchain through a standard data interface. The vendor subsystem may include registration application, account management, vendor information management, demand management, purchase management, channel management, funds management, serial number/SN number management, settlement management, and/or interface management. The universal terminal subsystem can comprise a registration application, terminal manufacturer management, terminal type management, serial number/SN number management, order state inquiry, interface management and other sub-modules. The channel subsystem can comprise a direct marketing module, an electronic commerce platform module, an off-line self-marketing channel, an off-line cooperation channel, an on-line incoming call, an on-line outgoing call, an assembly maintenance follow-up marketing module and the like. The federated chain platform may include sub-modules of distributed databases, consensus algorithm modules, BSN (blockchain service network) modules, interface management, and the like. The provider subsystem, the universal terminal subsystem and the channel subsystem can perform uplink management distribution through the alliance chain platform.
It can be understood that in the vendor subsystem, the core enterprise can firstly make purchases to each terminal manufacturer, and according to different types of purchase protocols, the modes of firstly making and then selling, firstly selling and then purchasing and one piece of replacing transmission are divided. Once the purchase is completed, the initial value can be set by the data such as serial number/SN number, etc. of the universal terminal through a supply system platform (B2B platform) in the vendor subsystem. And meanwhile, initializing and setting the terminal sales state in the universal terminal subsystem. And calling and data updating the universal terminal subsystem and related data in the channel subsystem according to different channel types and channel sales modes (bare computers, contracts and the like).
In a specific implementation, a core enterprise can be selected as a trusted core node in a provider subsystem by default in an initial stage, and then a sub-node 1 and a sub-node 2 are respectively arranged in a universal terminal subsystem and a channel subsystem. And encrypting and synchronizing the related data of the upstream and downstream of the supply chain in the core node to the node 1 of the universal terminal subsystem and the node 2 of the channel subsystem through an SHA-256 algorithm. And a supervision node S can be arranged in the universal terminal subsystem to backup the original state data in the universal terminal subsystem, and the core node transmits the original backup file S1 of the supervision node S to the universal terminal subsystem node 1 and the channel subsystem node 2. The backup file s1 backs up terminal manufacturer information, terminal type information, serial number information, order status information in the current state, and the like.
Step S20: and decrypting the original backup file through the plurality of child nodes, and generating an initial consensus document according to the decrypted files corresponding to the plurality of child nodes and the original backup file.
It should be noted that the node status of each subsystem will change gradually as the trade order is generated. If the initial state of the order is x, the node 1 of the universal terminal subsystem, the node 2 of the channel subsystem and the core node decrypt the original backup file transmitted by the supervision node by using the private key according to the algorithm rule of the node 1 of the universal terminal subsystem, and the node 1 and the node 2 respectively form a preliminary consensus mechanism document a of the whole system together with the original backup file transmitted by the supervision node and the decrypted file of the node 2 of the universal terminal subsystem. I.e. consensus document a=decrypted file of node 1+decrypted file of node 2+original backup file. Data structure of consensus document reference may be made to fig. 5, fig. 5 being a schematic diagram of a data structure implemented by a consensus document in the first embodiment of the present invention.
Step S30: when the order state information is changed into a finished state, the sub-node service information data in the plurality of sub-nodes are sent to a packing transmission synchronization sequence through the alliance chain platform, and the sub-node service information data are sent to the core node and the supervision node according to a preset frequency.
It will be appreciated that when the order state changes to z, such as the finished state. The Servi information data in the node 1 of the universal terminal subsystem and the node 2 of the channel subsystem (wherein the Servi data in the node 1 and the node 2 can refer to original various product, service and service state data in the universal terminal subsystem and the channel subsystem, and belongs to the bottom layer original data generated in the universal terminal sales system) are put into a packaging transmission synchronization sequence through the alliance chain platform, and broadcast to the central node and the supervision node S according to a preset frequency (for example, one time interval every 10 minutes).
Step S40: and verifying the plurality of sub-nodes and the monitoring node through the core node, sending feedback information to the plurality of sub-nodes, and performing consensus verification according to the core service information data of the core node and the feedback information to obtain verification feedback information.
Step S50: updating the initial consensus document according to the verification feedback information to obtain a final consensus document comprising the initial consensus document, the verification feedback information and the core service information data, encrypting the data of the final consensus document, and transmitting the encrypted data to the plurality of child nodes.
It should be understood that the core node may complete the verification of the universal terminal subsystem node 1, the channel subsystem node 2 and the supervisory node S through a timing task, synchronously send feedback information to the node 1 and the node 2, and simultaneously combine the Servi information of the core node itself (where the information of the core node Servi may be the product, service and service data in the provider subsystem) to perform the consensus verification, asynchronously complete the updating and storage of the data, and the system completes the final consensus document c of the whole system on the basis of the consensus document a, that is, c=the consensus document a+ verification passes the feedback information+servi information.
Finally, the data in the consensus document c can be synchronized to the node 1 of the universal terminal subsystem and the node 2 of the channel subsystem through the SHA-256 encryption data by the core node.
In this embodiment, it is disclosed that the original state data is backed up by the target child node, and the original backup file is encrypted and sent to a plurality of child nodes by the core node; generating an initial consensus document according to the decrypted file and the original backup file; the information intercommunication is realized through the initial consensus document; when the order is in the ending state, the service information data of the child node is sent to the core node and the supervision node; checking the plurality of child nodes and the monitoring node through the core node, and performing consensus checking according to the core service information data and the feedback information of the core node; the initial consensus document is updated according to the verification feedback information, and the final consensus document is encrypted and then sent to a plurality of sub-nodes, so that supervision can be performed through the consensus document and the supervision nodes, the encryption processing ensures that the information cannot be tampered, and consistency and accuracy of state data information in each platform are realized.
Referring to fig. 6, fig. 6 is a flowchart illustrating a second embodiment of a data updating method based on a blockchain consensus mechanism according to the present invention.
Further, before the order state information is changed into the finishing state, verification can be performed according to the change information of the order, and the consensus document is updated in real time, so that supervision on the state data information is realized, and the problem that the state data information is inconsistent in each platform is avoided. Therefore, based on the first embodiment, in this embodiment, after the step S20, the method further includes:
step S201: and verifying the decryption file through the plurality of child nodes, and sending first feedback information to the core node.
It can be understood that the decrypted files can be verified through the node 1 of the universal terminal subsystem and the node 2 of the channel subsystem, and the node 1 and the node 2 send acknowledgement information to feed back to the core node.
Step S202: and when the order state information changes, backing up the first feedback information through the supervision node to generate a feedback backup file.
It should be understood that, when the order state is changed to y, the pan-terminal subsystem node 1 sends the feedback information received by the core node to the supervisory node S for backup storage, so as to form a backup file S2.
Step S203: and updating the initial consensus document according to the feedback backup file to obtain an intermediate consensus document comprising the decryption file corresponding to the target child node, the feedback backup file and the initial consensus document.
It can be understood that the system updates the original consensus document a information to a 'according to the backup file S2 of the supervisory node S in the y state, and at this time, a' =the node 1 decryption information+s2 file. The consensus document a is further updated to an intermediate consensus document b of the whole system, i.e. b=a+a' at this time, i.e. b file=node 1 decryption file+s2 file+consensus document a.
Similarly, when the order state is changed to y and then changed from the state y to z, the consensus document b can be further updated to be a final consensus document c of the whole system, and then the c document=the node 1 decryption file+s2 file+the consensus document a+the verification passes the feedback information+servi information.
Further, the consensus mechanism can be updated by selecting core nodes, child nodes and supervision nodes in the supply chain link points in turn, so that the data transmission authenticity, the data self-verification and the data non-tamper-resistance are ensured. Therefore, after the step S50, the method further includes: selecting other nodes from the supply chain link points as the core nodes according to a preset rule, taking the rest nodes in the supply chain nodes as the plurality of sub-nodes, wherein the plurality of sub-nodes comprise the target sub-node, and the supervision node is arranged in the target sub-node; and executing the step of backing up the original state data in the target child node through the target child node, encrypting the original backup file through the core node and then sending the encrypted original backup file to the child nodes until the final consensus document is updated, encrypting the data of the updated consensus document and then sending the encrypted data to the child nodes.
It will be appreciated that other nodes may be selected from the supply link points as core nodes according to a predetermined rule, which may be selected in the order of the supply link nodes stored in the predetermined table. When selecting the core node, a certain terminal model of a certain brand terminal manufacturer can be selected from the universal terminal subsystem to be used as a node which is trusted by the universal terminal subsystem and set as the core node, at the moment, the node 1 is set in the channel subsystem, the node 2 is selected from the provider subsystem, meanwhile, a supervision node S is selected from the channel subsystem, the steps from S10 to S50 in the first embodiment are repeated, and the data transmission step is carried out to form a consensus document c'. And updating on the basis of forming the consensus document c in the seventh step, and perfecting the system to form the consensus document d of the whole system, namely d=c+c'.
Further, if the generated data change is inconsistent with the authenticated consensus document, single node individual modification in other subsystems does not pass other node authentication, the original document state can be returned, and the consistency of the data in each node is ensured. Therefore, after the step S50, the method further includes: decrypting the initial consensus document, the intermediate consensus document, the final consensus document and the updated consensus document, and integrating the decrypted document based on order identification to obtain an integrated consensus document; verifying the consensus document in the plurality of child nodes and the integrated consensus document; and returning the order state information to the state before the change when the verification fails.
It can be understood that the common documents a, b, c and d can be processed by a decryption algorithm, based on the serial number/SN number, the common document e in which the same content forms the whole supply chain system is taken under the same order state, the encrypted common documents in the other subsystems are verified with the e document, and if the encrypted common documents are different, the encrypted common documents are returned to the content of the last common document by the system. That is, the data cannot be updated, and the data is returned to the data of the last updating step.
Referring to fig. 7, fig. 7 is a schematic diagram illustrating an implementation of the universal terminal sales supply chain platform consensus mechanism of the present invention. Through the steps in fig. 7, each subsystem in the universal terminal sales system completes the data information consensus of each node, and completes the consistency of data update. And if the single node in the other subsystems is independently modified and is not authenticated by the other nodes, the original document state is returned by the system.
Further, the multiple subjects in the supply chain node can be weighted according to a preset scoring standard, so that the subject with the best qualification is selected as a core node, and the reliability of the system is improved. Therefore, after the step S50, the method further includes: scoring each dimension of the plurality of subjects in the supply chain node according to a preset scoring standard; weighting and summing the scoring values of the dimensions to obtain the weight values of the plurality of subjects; and sequencing the plurality of subjects according to the weight values of the plurality of subjects, and selecting the subject with the highest weight value as a core node.
It will be appreciated that the core node may be selected by the following steps. Scoring each relevant enterprise and main body with independent identification in the three-major sub-platform system, wherein the main body comprises suppliers, channel providers, platform providers and the like according to the dimensions of enterprise credit level T, sales quantity s, customer satisfaction (evaluation) Q and the like; weighting and summing all relevant enterprises or main bodies of the three-large subsystem platform according to the scoring of all dimensions to obtain weight values of all relevant enterprises and main bodies; and sequencing the related parties in the three subsystems according to the weight values, and selecting the related party with the highest value in each three subsystems as a core node. Meanwhile, the time t can be recorded, the weight value of each enterprise and each main body can be further updated according to the change of the time t, and meanwhile, the related party information is dynamically updated to serve as a core node.
In this embodiment, it is disclosed that the decryption file is checked by a plurality of child nodes, and first feedback information is sent to the core node; when the order state information changes, the first feedback information is backed up through the monitoring node, and a feedback backup file is generated; and updating the initial consensus document according to the feedback backup file to obtain an intermediate consensus document comprising the decryption file corresponding to the target child node, the feedback backup file and the initial consensus document. Because the embodiment can verify according to the change information of the order before the change of the order state information is in the finishing state, and update the consensus document in real time, the supervision of the state data information is realized, and the problem that the state data information is inconsistent in each platform is avoided.
Referring to fig. 8, fig. 8 is a flowchart illustrating a third embodiment of a data updating method based on a blockchain consensus mechanism according to the present invention.
Further, as the universal terminal sales are aimed at the universal terminal of the e-commerce channel sales, after the channel type is judged, a special consensus mechanism algorithm can be designed aiming at the universal terminal sales of the e-commerce channel type, the order and the serial number set information are subjected to uplink processing, and the credible serial number is selected to bind with the order through a supervision mechanism of other sub-platforms of a alliance chain, so that the consistency of the serial number state is ensured. Therefore, based on the first embodiment, in this embodiment, after the step S50, the method further includes:
step S501: submitting order information of an e-commerce channel to the alliance chain platform through the channel subsystem, and submitting a universal terminal serial number to the alliance chain platform through the universal terminal subsystem.
Step S502: and distributing an account address and a secret key to the order information and the universal terminal serial number through the alliance chain platform.
Step S503: when a terminal receiving the order information initiates a binding serial number request to a terminal of the universal terminal serial number, randomly selecting a target serial number from the universal terminal serial number, encrypting the target serial number according to the secret key of the order information, and feeding back the encrypted target serial number to the terminal corresponding to the order information.
Step S504: after the terminal corresponding to the order information decrypts the encrypted target serial number through the secret key, the order information is updated according to the target serial number, and the state of the target serial number is updated to be a locking state through the terminal of the universal terminal serial number.
Step S505: and sending the shipped state of the target serial number to a logistics center and the alliance chain platform through the universal terminal subsystem.
It is understood that the order information M (information such as client number, model, contract bundle, etc.) of the e-commerce channel may be submitted to the coalition chain platform for validation through the channel subsystem. Meanwhile, the universal terminal manufacturer uploads the corresponding universal terminal serial numbers to the alliance chain platform uplink through the universal terminal subsystem to take effect. The federation chain platform then assigns corresponding account addresses and keys (Ads 1, S1), (Ads 2, S2) to M and L, respectively. M initiates a request for binding the serial number to L through the account address and the secret key, and the system randomly extracts a target serial number lis1 from L, encrypts the serial number through the secret key of M and returns the serial number to the M order through the address. Decrypting the order M through a secret key, and updating the target serial number lis1 information and the M order information to generate new order information M'; the sync string number set L updates the state of the selected target string number lis1 from the original available state to the locked state. And finally, the universal terminal subsystem transmits the target serial number List 1 to the logistics center for delivery/dispatch, changes the serial number state into delivered state, and distributes the serial number to the alliance chain platform.
Further, if the customer cancels the order, after the universal terminal re-warehouse-in, the state of the order information and the target serial number can be rolled back to the state of the data before the step of updating, so that the consistency of the serial number state can be ensured. Therefore, after the step S505, the method further includes: and when an order canceling instruction is received, rolling back the state of the order information and the target serial number to the data before the step of updating the order information according to the target serial number and updating the state of the target serial number into a locking state through the terminal of the universal terminal serial number.
It can be understood that if the customer cancels the order, after the universal terminal re-enters, the state of the target string number list 1 needs to be rolled back, and meanwhile, the states of the list 1 string number and the L string number set are updated. The related subsystem can check the update execution conditions of related states such as orders, serial numbers and the like at any time through an interaction mechanism of the supervision node S of other sub-platforms of the alliance chain, and the system selects the credible serial numbers to bind with the orders, so that the consistency of the serial number states is ensured.
In the embodiment, a universal terminal for the e-commerce channel sales is disclosed, after the channel type is judged, a dedicated consensus mechanism algorithm can be designed for the e-commerce channel type universal terminal sales, the order and the serial number set information are subjected to uplink processing, and the trusted serial number is selected to bind with the order through a supervision mechanism of other sub-platforms of a alliance chain, so that the consistency of the serial number state is ensured.
