Detailed Description
The following detailed description of specific embodiments of the present application refers to the accompanying drawings. It should be understood that the detailed description is presented herein for purposes of illustration and explanation only and is not intended to limit the present application. 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 present application by showing examples of the present application.
Existing redemption strategies for virtual resources (e.g., points) suffer from the following drawbacks: 1) The variety and the quantity of the virtual resources cannot be uniformly managed by merchants due to the wide variety, strong dispersibility and complicated exchange process of the virtual resources; 2) The value interpretation of the virtual resource is ambiguous and the exchange activity of the virtual resource is not timely reminded, so that a user cannot know the use condition of the virtual resource in real time, the virtual resource is idle, and the use rate of the virtual resource is reduced; 3) In the traditional management of virtual resources, a centralized service mode is mostly adopted, and the public confidence is lost, so that the ecological system of the virtual resources is slowly constructed; 4) The clearing of the virtual resource is complex, a great deal of labor cost and time cost are required to be consumed when the virtual resource is checked, the safety is low, and the operation cost of the virtual resource is increased.
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Fig. 1 shows a flowchart of a resource redemption method in an embodiment of the present application. The method is applicable to a server. As shown in fig. 1, the resource exchange method includes the following steps:
step S101, acquiring approval identifications of each alliance node to the first alternative exchange strategy from the blockchain network.
Wherein the first alternative redemption policy is a policy for redeeming different types of resources. For example, a first alternative redemption policy specifies redemption rules for two different types of resources (e.g., the redemption ratio of the first type of resource to the second type of resource is 1:2, etc.). Wherein the first type of resource and the second type of resource may be resources determined by categories of different industries (e.g., aviation resources and restaurant resources, etc.). The first alternative exchange strategy can improve the exchange efficiency of different types of resources and improve the utilization rate of the different types of resources.
In some specific implementations, the approval identifier may be an identifier that, when the different federation nodes confirm approval of the first alternative redemption policy, uses the private key of the federation nodes to sign the first alternative redemption policy twice, so as to ensure the security of the first alternative redemption policy.
In some implementations, the federation nodes include any one or more of resource holding nodes, resource redemption nodes, and resource generating nodes.
The resource holding node is a node with a certain type of resource, the resource exchange node is a node for exchanging different types of resources, and the resource generating node is a node for generating different types of resources.
Step S102, counting the strategy approval quantity corresponding to the first alternative exchange strategy according to the approval mark.
Step S103, determining whether the first alternative exchange strategy is effective or not according to the strategy approval quantity and a preset quantity threshold value.
The preset number threshold is a preset threshold, for example, when K coalition nodes are included in the blockchain network, the preset number threshold may be set to K/2. When the policy approval number is greater than or equal to a preset number threshold (i.e., indicating that more than half of the nodes in the blockchain network approve the first alternative redemption policy), the first alternative redemption policy is determined to be in effect. Otherwise, the first alternative redemption policy is determined to be invalid.
Step S104, under the condition that the first alternative exchange strategy is confirmed to be effective, generating and sending a resource exchange consensus mechanism into the blockchain network according to the first alternative exchange strategy.
After each alliance node in the block chain network obtains the resource exchange consensus mechanism, the resource exchange is carried out according to the resource exchange consensus mechanism.
In this embodiment, according to the obtained approval identifications of the alliance nodes to the first alternative exchange policy, the approval quantity of the policy corresponding to the first alternative exchange policy is counted, and the approval degree of the alliance nodes to the first alternative exchange policy is determined; determining whether the first alternative exchange strategy is effective according to the strategy approval quantity and a preset quantity threshold value, ensuring that the first alternative exchange strategy is effective when most alliance nodes in the blockchain network approve the first alternative exchange strategy, and replacing the old resource exchange strategy by using the first alternative exchange strategy; generating and sending a resource exchange consensus mechanism into the blockchain network according to the first alternative exchange strategy, so that each alliance node exchanges resources according to the resource exchange consensus mechanism, on the premise of ensuring the safety of resources, the resources of different types can be ensured to be fully used according to the resource exchange consensus mechanism, the management efficiency of the resources is improved, the rights and interests of users are ensured, and the cost of a resource operation platform is reduced.
In some implementations, before obtaining the approval identifications of the first alternative redemption policies by the respective coalition nodes from the blockchain network, further includes: generating a first alternative exchange strategy according to first type resources and preset type resources, wherein the first type resources are determined according to the service field corresponding to the alliance node; the first alternative redemption policy is transmitted to the blockchain network such that each coalition node analyzes the first alternative redemption policy to determine whether to approve the first alternative redemption policy.
And generating a first alternative exchange strategy through exchange modes (such as exchange conditions or exchange proportions) of the first type of resources and the resources of the preset type, so that the resources corresponding to different types of service fields can be exchanged, and the utilization rate of the resources is improved. Sending a first alternative exchange strategy to the blockchain network, analyzing the first alternative exchange strategy when each alliance node receives the first alternative exchange strategy, determining whether to approve the first alternative exchange strategy, and generating an approval mark when each alliance node approves the first alternative exchange strategy to characterize approval of using the first alternative exchange strategy to exchange resources; otherwise, when each coalition node does not approve the first alternative redemption policy, the first alternative redemption policy may be discarded, i.e., no approval identification is fed back to the resource redemption server.
In some implementations, before obtaining the approval identifications of the first alternative redemption policies by the respective coalition nodes from the blockchain network, further includes: counting the node number of alliance nodes in the blockchain network; and determining a preset quantity threshold according to the quantity of the nodes.
For example, by looking up a blockchain ledger, obtaining the number of nodes of the federation nodes in the blockchain network (e.g., including K nodes, K being an integer greater than or equal to 1), a preset number threshold may be set to K/2, or 2K/3, etc., which characterizes that most of the federation nodes in the blockchain network approve alternative redemption policies to be validated (e.g., first alternative redemption policies, etc.).
In some implementations, before obtaining the approval identifications of the first alternative redemption policies by the respective coalition nodes from the blockchain network, further includes: acquiring a second alternative exchange strategy sent by the alliance node from the blockchain network; verifying the private key signature of the second alternative exchange strategy, and generating an approval identifier corresponding to the second alternative exchange strategy under the condition that the private key signature is confirmed to pass verification; generating and sending a second broadcast message to the blockchain network according to the approval identifier of the second alternative exchange strategy and the second alternative exchange strategy so that the alliance node obtains the approval identifier of the second alternative exchange strategy and determines whether the second alternative exchange strategy is effective.
It should be noted that the second alternative exchange policy is an exchange policy generated by a certain alliance node according to a second class resource and a resource of a preset type, where the second class resource may be any one or several of a resource in a communication field, a resource in a service field and a resource in a traffic field.
The approval mark can be the mark that a certain alliance node carries out secondary signature on the second alternative exchange strategy by using a private key of the alliance node under the condition that approval of the second alternative exchange strategy is confirmed, so that the security of the second alternative exchange strategy is ensured.
In a specific implementation, the first alternative exchange policy and the second alternative exchange policy may be the same exchange policy, so that the exchange policies among the plurality of alliance nodes are consistent, and the update speed of the exchange policies is improved.
In some implementations, after generating and transmitting the resource redemption consensus mechanism into the blockchain network in accordance with the first alternative redemption policy, further comprising: and according to the resource exchange consensus mechanism, exchanging the first type of resources held by the current node into the resources of the preset type.
For example, the resource redemption consensus mechanism includes that the redemption ratio of the first type of resource and the preset type of resource is 1:2, the current node (e.g., the resource redemption server) has 4 parts of the preset type of resource and 1 part of the first type of resource, but only 6 parts of the preset type of resource can redeem the item required by the resource redemption server. At this time, the resource exchange server can exchange 2 parts of resources of a preset type by using 1 part of first type resources according to the resource exchange consensus mechanism, and after the resource exchange server performs resource exchange, the resource exchange server has (2+4) parts of resources of the preset type, so that the objects required by the resource exchange server can be exchanged, the utilization rate of the resources is improved, and the idle of the resources is avoided.
Fig. 2 shows a flow chart of a resource redemption method in a further embodiment of the present application. The method is applicable to a server. As shown in fig. 2, the resource exchange method includes the following steps:
step S201, obtaining the approval identification of each alliance node to the first alternative exchange strategy from the blockchain network.
It should be noted that, step S201 in the present embodiment is the same as step S101 in the previous embodiment, and will not be described herein.
Step S202, the approval identifications sent by the alliance nodes are saved in a redemption policy approval table.
Wherein the redemption policy acceptance table includes: any one or more of blockchain identification, approval identification and approval time information of each federation node.
It should be noted that, the redemption policy acceptance table is used to store the acceptance identifier of each coalition node for the first alternative redemption policy, so as to facilitate statistics on the acceptance identifier.
Step S203, counting the strategy approval quantity corresponding to the first alternative exchange strategy according to the approval mark.
It should be noted that, step S203 in the present embodiment is the same as step S102 in the previous embodiment, and will not be described herein.
Step S204, determining whether the first alternative exchange strategy is effective according to the strategy approval quantity and the preset quantity threshold value.
In some implementations, determining that the first alternative redemption policy is in effect based on the policy approval quantity and a preset quantity threshold includes: under the condition that the policy approval quantity meets the requirement of a preset quantity threshold value, acquiring time stamp information generated by a time stamp server; generating and sending broadcasting information to be validated to the blockchain network according to the timestamp information, the redemption policy approval table, the policy approval quantity and the first alternative redemption policies, so that each alliance node verifies the broadcasting information to be validated, and determining that the first alternative redemption policies are validated under the condition that the broadcasting information to be validated is verified by each alliance node.
It should be noted that, each federation node may confirm whether the first alternative redemption policy is approved by each federation node in the blockchain network by querying the redemption policy approval table, thereby ensuring fairness and fairness of the redemption policy update.
Step S205, under the condition that the first alternative exchange strategy is confirmed to be effective, generating and sending a resource exchange consensus mechanism into the blockchain network according to the first alternative exchange strategy.
It should be noted that, step S205 in the present embodiment is the same as step S104 in the previous embodiment, and will not be described herein.
In some implementations, after generating and transmitting the resource redemption consensus mechanism into the blockchain network in accordance with the first alternative redemption policy, further comprising: and determining the effective starting time of the resource exchange consensus mechanism according to the time stamp information.
The time stamp information can represent that the effectiveness of the first alternative exchange strategy is time information, so that each alliance node can synchronously use the first alternative exchange strategy to exchange resources, the consistency of resource exchange is ensured, and the utilization rate of the resources is improved.
In this embodiment, by storing the approval identifications sent by each federation node in the redemption policy approval table, statistics on the approval identifications are facilitated, and the approval speed for the first alternative redemption policy is increased. Under the condition that the policy approval quantity meets the requirement of a preset quantity threshold value, acquiring time stamp information generated by a time stamp server; generating and sending a broadcast message to be validated to a blockchain network according to the timestamp information, the redemption policy approval table, the policy approval quantity and the first alternative redemption policy, wherein the timestamp information can ensure that the validation time of each alliance node to the first alternative redemption policy is the same, and the consistency of resource redemption is ensured; and information such as approval identification is stored through the redemption policy approval table, so that fairness and fairness of redemption policy updating are guaranteed.

In addition, in order to highlight the innovative part of the present application, elements that are not so close to solving the technical problem presented in the present application are not introduced in the present embodiment, but it does not indicate that other elements are not present in the present embodiment.
Fig. 4 shows a block diagram of the components of the resource redemption system in an embodiment of the present application. As shown in fig. 4, the resource redemption system includes the following devices: a resource holding node server 401, a resource exchange node server 402, and a resource generating node server 403.
Wherein a resource holding node server 401, a resource exchange node server 402, and a resource generating node server 403, which are alliance nodes, are connected to each other through a blockchain network. In the blockchain network, a resource exchange consensus mechanism is achieved among all node servers, and the decentralized resource exchange account book is shared. The resources may be virtual resources such as points.
Fig. 5 shows a flow chart of a working method of the resource exchange system in the embodiment of the application. As shown in fig. 5, the working method comprises the following steps:
in step S501, the resource generating node server 403 generates and sends a first alternative exchange policy to the blockchain network according to the first type of resource and the preset type of resource, so that the resource holding node server 401 and the resource exchange node server 402 in the blockchain network obtain the first alternative exchange policy, and analyze the first alternative exchange policy to determine whether to approve the first alternative exchange policy.
The first type of resource is a resource determined according to the service domain corresponding to the resource generating node server 403. For example, the first type of resource may be any one or several of a resource in the aviation field, a resource in a banking system, a resource in the dining industry, and a resource in the communication field.
Before sending the first alternative exchange policy, the resource generating node server 403 needs to sign the first alternative exchange policy by using its own private key, and generate the signed first alternative exchange policy, so as to ensure the security of the first alternative exchange policy when transmitting in the blockchain network.
In step S502, the resource exchange node server 402 obtains the first alternative exchange policy sent by the resource generation node server 403 from the blockchain network, verifies the private key signature of the first alternative exchange policy, and when the verification is passed, if the resource exchange node server 402 approves the first alternative exchange policy, generates an approval identifier, and generates a first broadcast message according to the approval identifier.
The approval identifier may be an identifier that the resource exchange node server 402 uses its own private key to sign the first alternative exchange policy twice, and is used to characterize that the resource exchange node server 402 approves the first alternative exchange policy, and approves the exchange of the resource using the first alternative exchange policy.
In step S503, the resource exchange node server 402 sends a first broadcast message to the blockchain network, so that the resource generating node server 403 obtains the approval identifier of the resource exchange node server 402 for the first alternative exchange policy.
Meanwhile, the resource exchange node server 402 executes steps S502 to S503, and the resource holding node server 401 also synchronously executes steps S504 to S505, so as to determine whether the resource holding node server 401 accepts the first alternative exchange policy.
In step S504, the resource holding node server 401 obtains the first alternative exchange policy sent by the resource generating node server 403 from the blockchain network, verifies the private key signature of the first alternative exchange policy, and generates a approval mark if the resource holding node server 401 approves the first alternative exchange policy when the verification is passed, and generates a second broadcast message according to the approval mark.
The approval identifier may be an identifier that the resource holding node server 401 uses its own private key to sign the first alternative redemption policy twice, and is used to characterize that the resource holding node server 401 approves the first alternative redemption policy, and approves the redemption of the resource using the first alternative redemption policy.
In step S505, the resource-holding node server 401 sends a second broadcast message to the blockchain network, so that the resource-generating node server 403 obtains the approval identifier of the resource-holding node server 401 for the first alternative redemption policy.
In step S506, the resource generating node server 403 obtains, from the blockchain network, approval identifications of the resource holding node server 401 and the resource redemption node server 402 for the first alternative redemption policy, respectively.
In the blockchain network, there are N resource holding node servers 401 and M resource exchange node servers 402, where M and N are integers greater than or equal to 1. After the resource generating node server 403 obtains the approval identifications fed back by each node server, the resource generating node server 403 counts the number of received approval identifications for the first alternative redemption policy, and if the number of approval identifications is determined to be greater than or equal to a preset number threshold (for example, the preset number threshold is (m+n)/2), the first alternative redemption policy is determined to be accepted by most nodes in the blockchain network, where the resource generating node server 403 generates a resource redemption consensus mechanism according to the first alternative redemption policy.
In one implementation, the resource generating node server 403 may further send the resource redemption consensus mechanism to a timestamp server, so that the timestamp server can mark the effective time information of the resource redemption consensus mechanism according to the timestamp information when the resource redemption consensus mechanism is received.
In step S507, the resource generating node server 403 sends the resource exchange consensus mechanism to the blockchain network, so that each node server performs resource exchange according to the resource exchange consensus mechanism.
The resource redemption consensus mechanism may further include timestamp information, where the timestamp information is used to represent time of effectiveness information of the resource redemption consensus mechanism.
It should be noted that, in the blockchain network, each node server may update the resource exchange consensus mechanism, for example, the resource holding node server 401 and the resource exchange node server 402 may update and send the updated resource exchange consensus mechanism (for example, the resource holding node server 401 generates a second alternative exchange policy, the resource exchange node server 402 generates a third alternative exchange policy, etc.) to the blockchain network according to the exchange policy of different types of resources, so long as other nodes in the blockchain network can accept the second alternative exchange policy, that is, the approval identifier of the second alternative exchange policy acquired by the resource holding node server 401 is greater than or equal to the preset number threshold (or the approval identifier of the third alternative exchange policy acquired by the resource holding node server 402 is greater than or equal to the preset number threshold), and the resource exchange consensus mechanism in the blockchain network may be updated by using the second alternative exchange policy (or the third alternative exchange policy).
In some implementations, the different types of resources may be different types of points, such as any one or more of aviation points, banking points, dining points, and operator points.
In the embodiment, the approval degree of each node server to the first alternative exchange strategy is determined by acquiring approval identifications of each node server to the first alternative exchange strategy and counting the number of the approval identifications of each node server to the first alternative exchange strategy; when the number of the approval identifications of the first alternative exchange strategy is determined to be larger than or equal to a preset number threshold, the first alternative exchange strategy is determined to be effective, and when most alliance nodes in the blockchain network approve the first alternative exchange strategy, the first alternative exchange strategy is determined to be effective, and the old resource exchange consensus mechanism is replaced by the first alternative exchange strategy; the resource exchange consensus mechanism is sent to the blockchain network, so that each node server carries out resource exchange according to the resource exchange consensus mechanism, on the premise of guaranteeing the safety of resources, the resources of different types can be guaranteed to be fully used according to the resource exchange consensus mechanism, the management efficiency of the resources is improved, the rights and interests of users are guaranteed, and the cost of a resource operation platform is reduced.
