All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments described herein without making any inventive step shall fall within the scope of protection of this document.

Fig. 1 is a schematic view of an application scenario of an event wind control method based on a federation chain according to an embodiment of the present specification, where the scenario includes a federation chain including a federation master node and a member node, as shown in fig. 1. The union chain-based event wind control method provided in one or more embodiments of the present specification is applied to a union owner node and executed by the union owner node. Specifically, in the scenario of fig. 1, a target member node in the member nodes participates in a to-be-wind-controlled event as an event participant of the to-be-wind-controlled event, and issues a wind-controlled contract corresponding to the to-be-wind-controlled event in a federation chain, and then, an alliance master node obtains event information of the to-be-wind-controlled event, obtains the wind-controlled contract corresponding to the to-be-wind-controlled event from the federation chain according to the event information, and performs wind-controlled processing on the to-be-wind-controlled event according to the wind-controlled contract corresponding to the to-be-wind-controlled event. The method has the advantages that the wind control processing is carried out based on the alliance chain, the accuracy of the wind control result can be guaranteed by utilizing the characteristic that data in the alliance chain cannot be tampered, and the wind control result can be guaranteed to be approved by each member node by utilizing the characteristic that the data in the alliance chain are real and effective under the condition that a plurality of member nodes are used as event participants to participate in a wind control event to be treated.

Corresponding to the scenario in fig. 1, fig. 2 is a schematic flowchart of an event wind control method based on a federation chain according to an embodiment of the present specification, and as shown in fig. 2, the flowchart includes:

step S202, acquiring event information of a to-be-wind-controlled event; the event participants of the events to be subjected to the wind control comprise target member nodes in the alliance chain;

step S204, acquiring a wind control contract corresponding to the event to be wind controlled from the alliance chain according to the event information; a wind control contract corresponding to a to-be-wind-controlled event is issued in advance in a coalition chain by a target member node;

and step S206, carrying out wind control processing on the event to be wind controlled according to the wind control contract corresponding to the event to be wind controlled.

In this embodiment, the wind control processing is performed based on the federation chain, the accuracy of the wind control result can be ensured by using the characteristic that data in the federation chain cannot be tampered, and the wind control result can be ensured to be approved by each member node by using the characteristic that the data in the federation chain is real and effective under the condition that a plurality of member nodes participate in the wind control event to be treated as event participants.

In one embodiment, the to-be-weathered event is a loan application event of a user, the alliance owner node is a service device for providing a loan product end for the user, the alliance owner node is used for providing the loan product end for the user, for example, providing a loan APP for the user, and the user initiates the loan application event through the loan APP provided by the alliance owner node. The loan application event is participated by at least two target member nodes in the member nodes, the at least two target member nodes are service equipment of a financial institution for providing loan funds, and the funds required by the loan application event are provided by the financial institution to which the at least two target member nodes belong.

After the at least two target member nodes negotiate a loan item and determine the respective provided fund proportion, the at least two target member nodes issue a wind control contract for the loan item in the federation chain, and the wind control contract may include wind control rules for the user applying for loan. Therefore, after the user initiates a loan application event aiming at the loan project based on the APP provided by the alliance owner node, the alliance owner node can acquire the event information of the loan application event, extract the project name of the loan project from the event information, further acquire the wind control contract of the loan project from the alliance chain according to the project name, and perform wind control processing on the loan application event according to the wind control contract of the loan project.

Therefore, the event wind control method based on the alliance chain is applied to the loan scene, the wind control processing can be performed on the loan related events participated by multiple parties, the accuracy of the wind control result is ensured by using the characteristic that data in the alliance chain cannot be tampered, and the wind control result is ensured to be approved by each participant by using the characteristic that the data in the alliance chain is real and effective.

In an embodiment, in step S202, the ally leader node obtains event information of the event to be wind controlled, specifically: after a user initiates a to-be-wind-controlled event through a union main node, event information of the to-be-wind-controlled event is obtained, wherein the event information comprises an event name of an associated event associated with the to-be-wind-controlled event. Further, after the user initiates the event to be wind-controlled through the alliance master node, the event information of the event to be wind-controlled is acquired, which may specifically be: and after a user initiates a to-be-wind-controlled event through a user interaction end of the alliance main node, acquiring event information of the to-be-wind-controlled event.

As mentioned above, the federation master node may provide the user with a product end, which is the user interaction end described above. The product side may be a product side of a loan product. After a user initiates a wind control event to be controlled through a product end provided by a union master node, the union master node acquires event information of the wind control event to be controlled, wherein the event information comprises an event name of an associated event related to the wind control event to be controlled. The related event related to the event to be wind-controlled may be an event which causes the event to be wind-controlled, and the event information of the event to be wind-controlled includes an event name of the related event, and also includes information such as an event name of the event to be wind-controlled.

In one embodiment, the ally node provides a product end of a loan product to a user, and the user initiates a loan application event for a loan item based on the product end, where the loan item is the related event, the item name of the loan item is the event name of the related event, and the loan application event is the event to be controlled. In this embodiment, after a user initiates a loan application event for a loan item through a product end, an alliance node obtains event information of the loan application event, where the event information carries a item name of the loan item and an event name of the loan application event. Because the product end (namely the user interaction end) provided by the allied master node is used for initiating the event to be controlled by wind, and the event to be controlled by wind is correlated with the correlated event, the three of the user interaction end, the event to be controlled by wind and the correlated event can be determined to be corresponding to each other.

In the step S204, according to the event information, a wind control contract corresponding to the event to be wind controlled is obtained from the alliance chain. The wind control contracts are pre-published in the federation chain by the target member nodes. The method comprises the following steps: and searching a wind control contract corresponding to the event name of the associated event in the alliance chain to be used as the wind control contract corresponding to the event to be controlled. The method comprises the steps that wind control contracts corresponding to different associated events are stored in a coalition chain in advance, and the wind control contracts corresponding to the different associated events are issued in the coalition chain by corresponding member nodes in the coalition chain as event participants of the associated events.

As previously described, the associated event may be a loan item, and the pending event may be a loan application event for the loan item. When the loan funds involved in the loan program are provided by the financial institution in which the plurality of member nodes are located, the plurality of member nodes are both event participants for the loan program (event participants for the associated event) and event participants for the loan application event (event participants for the event to be moderated).

And for each loan item, the member nodes serving as event participants of the loan item issue the wind control contracts of the loan item in the alliance chain in advance, so that the wind control contracts corresponding to different loan items are stored in the alliance chain in advance, and the wind control contracts corresponding to different loan items are issued in the alliance chain by using the corresponding member nodes in the alliance chain as event participants of the loan item. When the wind control contract of the loan item is stored in the federation chain, the loan item can be stored in the form of a corresponding relation of the item name of the loan item-the wind control contract. Therefore, in step S204, the wind control contract corresponding to the event name of the associated event obtained in step S202 is searched in the federation chain, and is used as the wind control contract corresponding to the event to be wind controlled. Therefore, in the embodiment, for the loan item and the loan application event, the corresponding wind control contracts are the wind control contracts of the loan item, that is, the wind control contracts corresponding to the loan item and the loan application event are the same, and the wind control contracts may include the wind control rules for the user applying the loan.

In the above description, the related events are used as loan items, and the pending events are used as loan application events for the loan items. It should be emphasized here that the relationship between the associated event and the event to be wind-controlled is: the associated event associated with the event to be windcontrolled is the event that caused the event to be windcontrolled. Therefore, on the basis of following the relationship, the association event and the event to be controlled by wind are not limited to the above examples, for example, the association event may also be a business trip event, the event to be controlled by wind may also be a business trip reimbursement event, the association event may also be a purchase event, and the event to be controlled by wind may be a return event after purchase. The wind control contract corresponding to the to-be-wind-controlled event (i.e. the wind control contract of the associated event) may include a plurality of wind control rules for performing risk control on the user. The wind control contract corresponding to the to-be-wind-controlled event is pre-deployed in the alliance chain in the form of an intelligent contract, and the safety and effectiveness of the wind control contract corresponding to the to-be-wind-controlled event can be guaranteed.

After acquiring the wind control contract corresponding to the to-be-wind-controlled event, in step S206, performing wind control processing on the to-be-wind-controlled event according to the wind control contract corresponding to the to-be-wind-controlled event, where the step may specifically be: and executing each wind control rule included in the wind control contract corresponding to the to-be-wind-controlled event so as to perform wind control processing on the to-be-wind-controlled event.

In one embodiment, according to a wind control contract corresponding to a to-be-wind-controlled event, wind control processing is performed on the to-be-wind-controlled event, which specifically includes: and executing a wind control rule in a wind control contract corresponding to the to-be-wind-controlled event, and calling a corresponding wind control contract according to the wind control rule if the wind control rule indicates that other wind control contracts stored in the alliance chain need to be called in the executing process so as to perform wind control processing on the to-be-wind-controlled event.

Specifically, a plurality of wind control rules are recorded in a wind control contract corresponding to a wind control event, after acquiring the wind control contract corresponding to the wind control event, a master node executes each wind control rule in sequence according to an execution sequence marked among the plurality of wind control rules, and in the execution process, if a certain wind control rule indicates that other wind control contracts stored in a federation chain need to be called, the corresponding wind control contract in the federation chain is called according to the wind control rule so as to perform wind control processing on the wind control event. The called corresponding wind control contract can be issued by a member node in the federation chain, and the member node may or may not be a target member node participating in the event to be subjected to wind control.

For example, 3 wind control rules are recorded in a wind control contract corresponding to a to-be-wind-controlled event, which are a user credit wind control rule, a user repayment capacity wind control rule, and a user consumption capacity wind control rule, respectively, and the execution sequence is as follows: the method comprises the steps that a user credit wind control rule, a user repayment capacity wind control rule and a user consumption capacity wind control rule are carried out, when a union master node executes the user repayment capacity wind control rule, the rule is analyzed, it is determined that a wind control contract which is stored in a alliance chain and used for judging the repayment capacity of a user needs to be called is marked in the rule, and the union master node calls the wind control contract which is stored in the alliance chain and used for judging the repayment capacity of the user according to the mark to execute so as to carry out wind control processing on a wind control event. The wind control contract for judging the repayment capability of the user can be issued by a target member node participating in a to-be-wind-controlled event, can be issued by other member nodes in a alliance chain, and can also be issued by an alliance main node.

The foregoing describes a process of acquiring a wind control contract of a to-be-wind-controlled event and performing wind control processing on the to-be-wind-controlled event. It can be known that the wind contract of the to-be-wind event (i.e. the wind contract of the associated event of the to-be-wind event) is issued in the federation chain by the target member node participating in the to-be-wind event (i.e. the member node participating in the associated event). To ensure that a member node joining a federation chain is a true and reliable node, fig. 3 is a schematic flow diagram of an event wind control method based on a federation chain according to another embodiment of the present specification, and as shown in fig. 3, before acquiring event information of an event to be wind controlled, the method further includes:

step S302, acquiring a join request for requesting a join node to apply for joining a alliance chain;

step S304, according to the joining request, a first request event requesting the joining node to join the alliance chain is examined and approved;

and S306, after the first request event is approved, responding to the join request so as to enable the node requesting to join as a member node to join the alliance chain.

In step S302, the federation master node obtains a join request requesting the join node to apply for joining the federation chain. The joining requesting node is any node that wants to join the federation chain, including but not limited to the target member node described above. In step S304, the federation master node approves the first request event requesting the joining node to join the federation chain according to the joining request. And step S306, after confirming that the first request event is approved, the alliance main node responds to the join request so as to enable the join request node to be used as a member node to join the alliance chain.

In step S304, the federation master node approves the first request event requesting the joining node to join the federation chain according to the joining request, specifically: and voting the first request event according to the joining request, and/or sending a voting notification to the joined member nodes in the alliance chain according to the joining request so as to notify the joined member nodes in the alliance chain to vote for the first request event, and determining that the first request event passes the examination and approval when the voting result meets the corresponding preset requirement.

After receiving the join request, the alliance main node determines a first request event for requesting the join node to join the alliance chain. In one case, the ally leader node votes for the first requested event. In another case, the federation master node sends a voting notification to the member nodes that have joined the federation chain, informing the member nodes that have joined the federation chain to vote for the first requested event. In yet another case, the federation master node both votes for the first requested event and notifies member nodes that have joined the federation chain to vote for the first requested event.

When the voting result meets the corresponding preset requirement, for example, when the alliance master node agrees to request the joining node to join the alliance chain, or more than half of the member nodes already joining the alliance chain agree to request the joining node to join the alliance chain, or when the alliance master node and more than half of the member nodes already joining the alliance chain agree to request the joining node to join the alliance chain, the alliance master node determines that the first request event is approved, and responds to the joining request, so that the joining node is requested to join the alliance chain as the member node.

It can be understood that when any node wants to join the federation chain, it needs to vote based on the flow in fig. 3. It can be seen that through the flow in fig. 3, the security of the member node joining the federation chain can be ensured by voting.

As can be known from the foregoing description, a member node joining a federation chain, such as the target member node mentioned above, may issue a wind-control contract in the federation chain for a participating to-be-controlled event, that is, issue a wind-control contract in the federation chain for a participating associated event, and in order to ensure the legitimacy of the wind-control contract issued by the member node, fig. 4 is a flowchart of an event wind-control method based on a federation chain according to a further embodiment of this specification, as shown in fig. 4, before acquiring, according to event information, a wind-control contract corresponding to the to-be-controlled event from the federation chain, the method further includes:

step S402, acquiring a wind control contract release request of a target member node; the request carries a wind control contract corresponding to the event to be wind controlled;

step S404, according to the wind control contract issuing request, a second request event of the target member node requesting to issue the wind control contract corresponding to the wind control event to be issued is examined and approved;

and step S406, after the second request event passes the approval, responding to the wind control contract issuing request so as to issue the wind control contract corresponding to the to-be-controlled event in the alliance chain.

In the step S402, the franchise master node acquires a wind control contract issuing request of the target member node; the request carries a wind control contract corresponding to the event to be wind controlled. The method can be understood that the wind control contract corresponding to the to-be-controlled event is the wind control contract of the associated event associated with the to-be-controlled event. In the step S404, the ally master node determines that the target member node requests to issue the second request event of the wind control contract corresponding to the event to be controlled according to the wind control contract issue request, and approves the second request event. In step S406, after determining that the second request event passes the approval, the federation master node responds to the wind control contract issuing request to issue the wind control contract corresponding to the event to be controlled by wind in the federation chain.

Step S404, according to the wind control contract issuing request, the second request event of the target member node requesting to issue the wind control contract corresponding to the wind control event to be issued is examined and approved, specifically: issuing a request according to a wind control contract, voting a second request event, and/or issuing the request according to the wind control contract, and sending a voting notification to the member nodes added in the alliance chain so as to notify the member nodes added in the alliance chain to vote for the second request event; and when the voting result meets the corresponding preset requirement, determining that the second request event passes the approval.

After receiving the wind control contract issuing request, the alliance main node determines that the target member node requests to issue a second request event of the wind control contract corresponding to the wind control event to be issued. In one case, the ally leader node votes for the second request event. In another case, the federation master node sends a voting notification to the member nodes that have joined the federation chain, informing the member nodes that have joined the federation chain to vote for the second requested event. In yet another case, the federation master node both votes for the second requested event and notifies member nodes that have joined the federation chain to vote for the second requested event.

When the voting result meets the corresponding preset requirement, for example, when the alliance master node agrees with the target member node to issue the wind control contract corresponding to the wind control event to be issued, or when more than half of the member nodes which have joined the alliance chain agree with the target member node to issue the wind control contract corresponding to the wind control event to be issued, or when the alliance master node and more than half of the member nodes which have joined the alliance chain agree with the target member node to issue the wind control contract corresponding to the wind control event to be issued, the alliance master node determines that the second request event is approved, and responds to the wind control contract issuing request, so that the target member node issues the wind control contract corresponding to the wind control event to be issued in the alliance chain.

It can be understood that when any member node issues a wind control contract for any event to be controlled or any associated event, such as a wind control contract for any loan item, it needs to vote based on the flow in fig. 4. The method is the same as the conventional block chain, and after the member node issues the wind control contract, the wind control contract also needs to be identified by each node in the alliance chain, and the process is not repeated. It can be seen that through the flow in fig. 4, the validity of issuing the wind control contract can be ensured by adopting a voting manner.

In this embodiment, the alliance master node has a trusted Execution environment tee (trusted Execution environment). And the ally main node stores the wind control contract corresponding to the to-be-wind-controlled event in the TEE, and executes the wind control processing operation on the to-be-wind-controlled event according to the wind control contract corresponding to the to-be-wind-controlled event in the TEE, so that the safety of the wind control processing is ensured, and the data used in the wind control processing is made to be invisible.

In this embodiment, each member node also has a trusted execution environment TEE, and the member node sends, in the TEE, a join request requesting to join the federation chain and a wind control contract issuance request requesting to issue a wind control contract of a to-be-controlled event, so as to ensure that a process of joining the federation chain and a process of issuing the contract are authentic and trusted.

Fig. 5 is a schematic view of an application scenario of an event wind control method based on a federation chain according to still another embodiment of the present specification, where the scenario is described by taking a financial scenario as an example, as shown in fig. 5, the scenario includes a federation chain, where a federation chain has a federation owner bank node and an affiliate node, the federation owner bank node is the federation owner node, and the affiliate node is the member node. In fig. 5, the ally owner bank node may implement the node deployment in a cloud node or localized deployment manner, and the affiliated entity node may implement the node deployment in a cloud node or localized deployment manner.

Firstly, an alliance chain is established by an alliance owner bank node, the alliance owner bank node is provided with a product end, and the product end can realize functions of user registration, wind control processing, money release and the like. And then, the joint office node sends a joining application to the alliance owner bank node to request to join the alliance chain, and the alliance owner bank node creates a joining application event according to the joining application. And finally, the alliance owner bank node or the alliance organization node which has joined the alliance chain votes for applying for joining the event so as to permit or not permit the alliance organization node to join the alliance chain. In fig. 5, the franchise bank node and the franchise organization node both have TEE environments, establish a federation chain based on the TEE environments, implement wind control, implement that data is available and invisible, and provide a secure and trusted execution environment.

In fig. 5, if a plurality of affiliated enterprise nodes joining a federation chain participate in a related event together as an event participant of the related event, for example, share funds as a fund provider of a loan item, the plurality of affiliated enterprise nodes also participate in a pending event together as an event participant of a pending event associated with the related event, for example, participate in a loan application event for the loan item. Any one or more of the plurality of affiliated nodes may apply for a controlled contract for the loan item issued in the federation chain, the controlled contract also being a controlled contract for the loan application event. The wind control contract can be jointly researched and determined by the nodes of the plurality of joint organizations, and the contract development language is a language with complete graphic flexibility and supports the realization of various wind control logics.

After any one of the plurality of affiliated entity nodes issues a wind control contract for the loan item in the federation chain, the federation master bank node or the affiliated entity node that has joined the federation chain votes for an event that the application issues the wind control contract to permit or not permit issuance. The voting rules can be in various ways such as ally decision, 51% principle, designated member voting, and the like. The ally decision means that the ally permits issuing to be issued. The 51% principle refers to more than half of the nodes in the federation chain granting publishing. The designated member voting refers to that the designated member can vote. The wind control contract can record contract codes, wind control logic description, contract version, effective time and the like.

After issuing the wind control contract, as shown in fig. 5, the franchise main bank node is provided with a product end, the user can apply for loan at the product end, and after applying for loan, the franchise main bank node obtains a corresponding wind control contract from the alliance chain according to the name of the loan item, so that the wind control is performed on the event that the user applies for loan.

Fig. 6 is a functional schematic diagram of an alliance bank node according to an embodiment of the present disclosure, and as shown in fig. 6, in the scenario of fig. 5, the alliance bank node has the following functions: creating a alliance chain, configuring authority which is the authority of a worker configuring alliance main bank nodes, such as whether contract can be checked or not, voting nodes, freezing the behavior of member nodes in the alliance chain, voting contract voting, and applying for a released wind control contract for the member nodes.

Fig. 7 is a functional schematic diagram of an affiliate organization node provided in an embodiment of the present specification, and as shown in fig. 7, in the scenario of fig. 5, the affiliate organization node has the following functions: joining a alliance chain, applying for joining the alliance chain, voting the nodes applying for joining, issuing a wind control contract, voting the wind control contracts issued by other nodes, inquiring the historical issued wind control contracts, and the like.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
