Example one
Fig. 1 is a flowchart illustrating a data sharing method based on a federation chain and an incentive mechanism according to an embodiment of the present invention. Referring to fig. 1, the present embodiment provides a data sharing method based on a federation chain and a incentive mechanism, including:
step S1: the member organizations build respectively corresponding service nodes and first network nodes for storing data information, and the first network nodes to which the member organizations belong are sequentially accessed into a first alliance network to build a first alliance chain;
step S2: second network nodes for storing the integral information are generated according to the first network nodes, and the second network nodes are sequentially connected to a second alliance network to construct a second alliance chain;
step S4: sending a service request to a corresponding first network node through any service node and broadcasting the service request in the whole network, and correspondingly adjusting integral information in a second network node related to the service request type according to a whole network consensus result and/or the sent service request type;

When the specific implementation is carried out, the service platform consists of service nodes of all member organizations, the alliance chain platform consists of a first alliance chain and a second alliance chain, the member organizations initiate service requests through the respective service nodes and broadcast the service requests to the whole network of the first alliance chain through the respective first network nodes, after receiving the relevant requests, all the first network nodes can judge whether consensus is needed to be achieved in the first alliance chain and then execute the consensus on the basis of the initiated service request types, wherein when the initiated service request types are data uploading requests, data deleting requests and member complaint requests, the requests can be executed in the first alliance chain after the consensus agreement is needed to be achieved, and when the initiated service request types are data query requests, the requests can be directly executed without the consensus; in addition, after the initiated service request is executed in the first alliance chain, whether the executed service request type is a paid request is continuously judged, if yes, a certain integral reward or deduction needs to be given to a relevant party executing the operation at this time through the second alliance chain, wherein the data uploading request, the data inquiring request and the data deleting request are paid requests.
Through the implementation process, the first network node in the first alliance chain is used for storing the data information, the second network node in the second alliance chain is used for storing the point information, and the service node of each member mechanism, the first network node and the second network node are in one-to-one correspondence, so that the point information adjustment of the related member mechanism can be completed on the corresponding second network node after the corresponding service request is completed through the first network node. And then a 'paid' mode of utilizing shared data to replace points is created, each member organization is prompted to actively share valuable data in time, and the scale and the value of data sharing are improved.
Furthermore, it should be understood by those skilled in the art that the service request in the above embodiments is not limited to the four manners of the data upload request, the data delete request, the data query request and the member complaint request, but also includes other service requests that can be implemented, such as a data download request, a data change request, and the like.
It can be understood that, in this embodiment, the first federation chain is built by using a super ledger Fabric framework, and the second federation chain is built by using an Irppre framework having a point recording function, because the super ledger Fabric uses a modular framework technology, and an algorithm used by the super ledger Fabric is a Kafka consensus ranking method, the first federation chain has good extensibility and data processing efficiency. To facilitate an understanding of the Kafka consensus ordering method, the Kafka consensus ordering method is described below in connection with the first federation chain: the first network node correspondingly collects service requests (mainly indicating data uploading requests and data deleting requests) broadcast by other first network nodes, and identifies the validity and the sequence of the service requests. And packaging the corresponding service request into a block according to the consensus result, and returning the new block to the tail part of the block connected to the existing first network node by each first network node, thereby ensuring the data consistency of each first network node.
Specifically, the method for establishing the first alliance chain by establishing the service node and the first network node storing the data information corresponding to each member authority by the member authority and sequentially accessing the first network node to which each member authority belongs to the first alliance network includes:
generating first digital authentication certificates corresponding to the member organizations one by one, and returning the first digital authentication certificates to the corresponding member organizations; respectively building a first network node and a service node according to the first digital authentication certificate, and sequentially accessing the first network node to which each member institution belongs to a first alliance network to build a first alliance chain; the data information is divided into mechanism information and shared data information, wherein the data information is divided into the mechanism information and the shared data information, the mechanism information comprises a mechanism ID and a complaint identification, and the shared data information comprises an index value, a main key and a detail ciphertext.
Further, the method for sequentially accessing each second network node to the second alliance network to construct the second alliance chain according to the second network node which generates the storage integral corresponding to the first network node in the above embodiment;

It is readily understood that the initial integral of each member organization is zero.
In consideration of the fact that a new member organization is added, referring to fig. 2, the above embodiment further includes a step S3 between the step S2 and the step S4:
the new member mechanism applies for joining the first alliance chain and broadcasts mechanism information to each network node of the whole network; each member organization audits the organization information and broadcasts audit results to each first network node of the whole network; after the auditing results of all member organizations reach consensus agreement, generating a first digital authentication certificate, mapping a second digital authentication certificate according to the first digital authentication certificate, and respectively returning the certificate to a new member organization; the new member institution correspondingly builds a first network node and a second network node according to the first digital authentication certificate and the second digital authentication certificate, sequentially accesses the first network node to the first alliance chain, and sequentially accesses the second network node to the second alliance chain; and respectively updating the data information in each first network node of the whole network and the integral information in each second network node.
In specific implementation, a first network node of a new member institution is configured with a first digital authentication certificate, and a second network node of the new member institution is configured with a second digital authentication certificate, wherein the first digital authentication certificate and the second digital authentication certificate have the same record content, so that a public and private key pair in the first digital authentication certificate/the second digital authentication certificate is also the same, and the new member institution only needs to store any one pair of public and private keys.
Referring to fig. 3, when the service request type is a data upload request, the method in step S4 includes:
packaging the integral address and the uploaded data of the data uploading party into shared data, wherein the uploaded data comprises a main key, an index value and data details; the sharing data is input to a service node of a data uploading party by adopting an uploading method of an intelligent contract, and is broadcasted to the whole first alliance chain network; after the first alliance chain is agreed by the whole network consensus, updating the shared data in each first network node; broadcasting the index value of the shared data to a second alliance chain whole network through a corresponding second network node; and after the second alliance chain is agreed by the whole network, inputting n points into the point address of the data uploading party.
The method for packaging the credit address of the data uploading party and the uploading data into the shared data comprises the following steps:
desensitizing the primary key of the uploaded data to obtain a primary key ciphertext; encrypting the data details by using a public key of a data uploading party to obtain a detail ciphertext; and packaging the master key ciphertext, the detail ciphertext and the integral address of the data uploading party to form shared data.
In a specific implementation process, when any member mechanism finishes packaging shared data and initiates a data uploading request through a corresponding service node, the first alliance chain searches for duplicate checking in the database according to a primary key in the shared data, and broadcasts to the first alliance chain in the whole network after the duplicate checking is passed (the shared data is not stored in the database), so that the shared data is prevented from being repeatedly uploaded and further limited resources of the database are avoided.
Referring to fig. 4, when the service request type is a data deletion request, the method in step S4 includes:
a data uploading party acquires an index value of deleted data; signing the deleted data by using a private key of a data uploading party to obtain signed data; signature data and an index value are input through a service node of a data uploading party by a deleting method of an intelligent contract, and are broadcasted to the whole first alliance chain network; each first network node verifies the signature data, deletes the data corresponding to the signature data in the first network node after the global consensus agrees, and completes the data update of each first network node; broadcasting the index value of the deleted data to the second alliance chain whole network through a second network node of a data uploading party; and after the second alliance chain is agreed by the whole network, outputting n points from the point address of the data uploading party.
When the method is implemented specifically, data uploading and data deleting are a relative process, the reward points of the system can be obtained when the data are uploaded, and similarly, when a data uploading party needs to delete the originally uploaded data, the equivalent points are correspondingly consumed; in addition, in order to encourage the member institutions to upload high-value shared data, different levels of credit remuneration can be set according to the value of the shared data so as to guide the member institutions to reduce the uploading of low-value shared data.
Considering that each member institution in the alliance chain platform has a transfer service, in order to improve the convenience of mutual transfer of each member institution, the embodiment meets the service requirement of the traditional transfer through the form of integral transfer; the specific integral transfer method comprises the following steps:
the member institution of the payer inputs m points of transfer and the point address of the payee through the service node; transferring m points in the point address of the payer to the point address of the payee by adopting a transfer method of an intelligent contract to complete the point transfer transaction; and then broadcasting the information of the point transfer transaction to the second union chain whole network.
Further, referring to fig. 5, when the service request type is a data query request, the method in step S4 includes:
