Detailed Description
A credit closed-loop service, which means that for some merchants engaged in services related to user credit, data related to the user credit can be shared to a credit evaluator, the credit evaluator generates a user credit record based on the information, and the generated user credit record is maintained; the credit evaluation party can reach the user based on the maintained credit records and the channels of the credit evaluation party to reversely monitor and promote the user to actively perform, so that the maintained credit records of the user are continuously accumulated to form a business mode of a business closed loop.
In this specification, it is in the business context of the credit closed-loop business that a technical scheme of setting up a credit record sharing platform by using the blockchain technology is proposed, so that the sharing of the credit records can be performed rapidly in a decentralization manner by relying on the architecture of the blockchain between each node device (merchant) joining the blockchain.
When the method is implemented, an operator of the blockchain can build a blockchain network formed by a plurality of merchant node devices in advance, and deploy credit closed-loop service by relying on the blockchain network, so that merchant node devices joining the blockchain network can share the user credit records in different merchants by broadcasting and releasing the user credit records into a distributed database (namely a distributed account book) of the blockchain.
For each merchant node device in the blockchain, the current billing period can be collected, the current billing period is broadcast to the blockchain by each merchant node device, the user credit records passing through the node devices are verified together, candidate blocks are created based on the collected user credit records, and then the consensus processing of the user credit records recorded in the candidate blocks is initiated in the blockchain based on the consensus algorithm supported by the blockchain network so as to 'compete' the billing authority.
If the consensus is complete, the merchant node device is determined to be an unanswered node, the merchant node device may publish the candidate block as the latest block broadcast to the blockchain network, adding the latest block to the blockchain's distributed database.
On the one hand, since the blockchain has historical traceability and non-tamper-resistance, user credit records generated in a period of time can be truly recorded on the blockchain in this way, and all user credit records can be traced on the blockchain; moreover, as the user credit records are verified and maintained by all the node devices together, and the tampering of the user credit records is required to be performed, most of the node devices are required to be controlled, so that the fairness of the user credit records can be ensured;
on the other hand, because the user credit records generated by each node device in the blockchain are shared, each node device can acquire the user credit records issued by other node devices by inquiring on the chain, so that a credit closed loop can be not concentrated on one node device, and each node device can share and monitor each other; in addition, when the credit closed-loop service is deployed, channels reaching users are correspondingly increased, and a plurality of node devices can jointly monitor and promote the positive performance of the users by using the credit records of the users on a chain to jointly collect, jointly punish and abstinence, jointly motivate the users and the like.
The following description is made by specific embodiments and with reference to specific application scenarios.
Referring to fig. 1, fig. 1 is a block chain-based credit record sharing method according to an embodiment of the present disclosure, which performs the following steps:
step 102, collecting user credit records broadcast and released to the blockchain by each node device in the blockchain in the current billing period by the target node device in the blockchain, and jointly verifying the user credit records by each node device in the blockchain;
step 104, initiating consensus processing of the collected user credit records in the blockchain to determine an accounting node device;
if the target node device is determined to be an accounting node, a blockbroadcast created based on the collected user credit records is published to the blockchain for storage in a distributed database of the blockchain, step 106.
The blockchains described in this specification may include, in particular, any type of blockchain network.
For example, in one embodiment shown, the blockchain may be a federated chain consisting of several merchant node devices. Each merchant can rely on the alliance chain to issue the user credit records generated by some online or offline service related to the user credit in the blockchain and record the user credit records in the distributed database of the blockchain so as to realize sharing of the user credit records of each merchant.
Wherein in one embodiment shown, the blockchain may specifically include a main chain, and a plurality of sub-chains anchored to the main chain;
for example, taking the above blockchain as an example of a coalition chain made up of a number of merchant node devices, the coalition chain may be divided into a backbone and a number of sub-chains, anchored to the backbone, corresponding to different merchant types, based on the specific type of merchant that is a member of the coalition (e.g., the industry type of service provided by the merchant).
The node devices may include any type of electronic device capable of joining as a member to the blockchain; for example, the electronic device may include, but is not limited to, a PC terminal, a mobile terminal, a server, etc. of a merchant.
The credit records may specifically include any form of data record capable of reflecting the credit status of the user; such as usage records, performance records, breach records, etc. for credit-related services.
The billing period refers to the time interval over which any two blocks on the blockchain are linked to the blockchain's distributed database. Accordingly, the current billing period refers to the time interval between the time when the latest block on the distributed database of the blockchain is linked to the distributed database and the time when the billing node successfully links the next block to the distributed database. The specific value of the accounting period may be set by the operator of the blockchain based on the actual service requirement, and is not particularly limited in the present specification; for example, the billing period for a blockchain network is 10 minutes, with a new block generated every 10 minutes.
The technical scheme of the present specification will be described in detail below by taking the target node device as a merchant node device and the blockchain as a alliance chain formed by a plurality of merchant node devices as an example.
Referring to fig. 2, fig. 2 is a schematic diagram of a federation chain as shown in the present specification.
As shown in fig. 2, the operator of the blockchain may pre-build a coalition chain composed of several merchants engaged in the service related to the user credit, and the merchant node devices of the merchants may be used as coalition chains to access the coalition chain.
In one embodiment shown, each merchant node device may carry a key algorithm for generating a private key and a public key, and when the merchant node device accesses the federation chain as a member device, the merchant node device may first create a pair of the private key and the public key by carrying the hardware for generating the private key and the public key or invoking the carried key algorithm. Or in practical application, the private key and the public key held by each merchant can be uniformly distributed and issued by the operators of the alliance chain.
Each merchant node device may then further construct a transaction (transfer) for initiating registration and sign the transaction based on the generated private key and then publish the transaction in the federation chain to apply for joining the federation chain. And after receiving the transaction, the member node device partially designated in the alliance chain can verify the signature of the transaction based on a public key corresponding to a private key used when signing the transaction, and after the signature verification is passed, can perform consensus processing on the transaction, and after the consensus is passed, allows the merchant node device to join the alliance chain, and can calculate the public key of the merchant node device to create an account address in the alliance chain for the merchant node device. At this time, the merchant node device is used as a member node device to successfully join the alliance chain, and the account address generated for the merchant node device is the identity of the merchant node device on the alliance chain.
After the alliance chain formed by a plurality of merchant node devices is built, an operator of the alliance chain deploys the credit closed-loop service by relying on the alliance chain. And merchants joining the alliance chain can share the user credit records among different merchants by broadcasting the user credit records to the distributed database of the alliance chain through merchant node equipment.
Referring to fig. 3, fig. 3 is a flowchart illustrating a merchant sharing user credit records based on a coalition chain.
As shown in fig. 3, a merchant node device may obtain a user credit record to be published and may then initiate billing to the federation chain based on the obtained user credit record.
The credit record of the user to be issued can be manually input by a merchant through merchant node equipment, or can be automatically generated by the merchant node equipment based on service data generated when the service related to the credit is provided for the user. That is, the merchant node device may obtain a user credit record manually entered by the merchant as a user credit record to be issued; user data records automatically generated based on service data generated by the user may also be obtained as user credit records to be published.
The specific format of the user credit record is not particularly limited in this specification, and in practical application, a standard set of data formats may be customized for the federation chain by the operator of the federation chain based on actual requirements.
For example, in one embodiment shown, the user credit record may be a data record consisting of the following fields:
and a timestamp field for populating a timestamp of entry or generation of the user credit record. The time stamp can be specifically obtained by inquiring a deployed time stamp server.
A type field for populating a type identifier of the user credit record. Operators of the coalition chain can define various types of user credit records based on actual requirements; for example, in one example, an operator of the federation chain may define three types of user credit records, a "service usage record", a "service violation record", and a "service performance record", and define a corresponding type identifier for each of the three types of records.
And the record content field is used for filling specific content of the user information record.
A user identity field for filling the user identity corresponding to the user credit record; such as an identification number, a social security code, etc.
A certification material field for filling a certification material for certifying the validity of the user credit record; for example, taking the above-mentioned user credit record as a "service performance record" as an example, the above-mentioned certification material may specifically be user data capable of certifying that the user has completed performance; for example, taking the "service performance record" as an "performance service record of a shared product" as an example, the above-mentioned proof material may specifically be order data, deposit payment record, etc. of a user planning the shared product on schedule.
With continued reference to fig. 3, when the merchant node device initiates billing to the federation chain based on the obtained user credit records, the merchant node device may specifically broadcast the user credit records in the federation chain.
In one embodiment shown, the merchant node device may construct a transaction using the user credit record to be issued as transaction content, and then sign the transaction based on the held private key.
With continued reference to fig. 3, after receiving the transaction, other node devices in the federation chain may verify the transaction, and after the verification is passed, broadcast the verification result in the federation chain;
In the present specification, the verification of the transaction may specifically include identity verification of the issuer of the transaction and verification of the transaction content; wherein, the verification of the transaction content can further comprise the integrity verification of the transaction content and the validity verification of the transaction content,
in implementation, when signing the transaction, the merchant node device may typically calculate a content digest (such as a hash value) for the transaction, and then encrypt the content digest based on the held private key to obtain a digital signature. After receiving the signed transaction, other node devices can decrypt the digital signature based on the public key of the merchant node device; if the decryption is successful, the identity verification of the merchant node device issuing the transaction is passed, and the transaction is a legal transaction issued by the merchant node device.
Secondly, other node devices can further calculate the transaction again to obtain a content abstract, and then match the recalculated content abstract with the original content abstract obtained by decrypting the digital signature; if the two match, the integrity verification of the transaction content is passed, and the transaction content of the transaction is not illegally tampered in the transaction transmission process.
Further, after the merchant node device completes the identity verification of the issuer of the transaction and the integrity verification of the transaction content, the validity verification of the user credit record may also be performed based on the information recorded in the user credit record as the transaction content. For example, the merchant node device may read the certification material filled in the "certification material field" in the user credit record to verify the validity of the user credit record.
With continued reference to fig. 3, after the transaction issued by the other node devices to the merchant node device passes the verification, the verification result may be broadcast and issued in the coalition chain; other node devices may sign the verification result based on the held private key, and the node device that receives the verification result may verify the data signature of the verification result based on the public key corresponding to the private key, which is not described in detail in the present specification.
Correspondingly, after the credit records of the users to be distributed are acquired, other node devices can also construct transactions in the same way, and broadcast and release are carried out on the alliance chain; if the merchant node device receives the transaction issued by other node devices, the transaction can be verified in the same manner, and then the verification result is broadcasted to the alliance chain, which is not described in detail in the present specification.
In this specification, the merchant node device may collect user credit records broadcast by each node device in the blockchain (including the merchant node device) to the coalition chain in the current billing period, and collectively verified by each node device in the coalition chain.
The common authentication passes, specifically, authentication passes through most node devices in the alliance chain. In the federation chain, as long as the user credit records are verified by most node devices in the federation chain, after the recognition of the common recognition of the most node devices in the federation chain is obtained, the user credit records are considered to be verified by all node devices in the federation chain.
In one embodiment, when the merchant node device broadcasts and publishes to the federation chain by each node device in the blockchain in the current billing period and the node devices in the federation chain jointly verify the passed user credit records, the merchant node device may specifically collect the user credit records broadcast and published to the federation chain by each node device (including the merchant node device) in the federation chain in the current billing period; collecting verification results of user credit records broadcasted and released to the blockchain in the current billing period by each node device in the alliance chain; and screening out user credit records broadcast and issued to the blockchain by each node device in the blockchain in the current billing period based on the collected information, and verifying the passed user credit records by the node devices with preset proportion in each node device.
The value of the above preset proportion is not particularly limited in the present specification, and may be specifically any ratio greater than 50%; such as 51%, or 100%.
In this specification, when the merchant node device collects the user credit records that are broadcast by each node device in the blockchain and issued to the coalition chain in the current billing period and are jointly verified by each node device in the coalition chain, a candidate block can be constructed based on the collected user credit records, and then based on the consensus algorithm supported by the coalition chain, the consensus processing of the user credit records recorded in the candidate block is initiated in the coalition chain to "compete" for the billing authority.
The specific type of the consensus algorithm supported in the federation chain is not limited in this specification, and in practical application, some classical consensus algorithms (such as PBFT algorithm) suitable for use in the federation chain may be adopted, or some consensus algorithms capable of efficiently processing transactions may be customized by an operator of the federation chain based on actual service requirements.
In one embodiment, the consensus algorithm supported in the federation chain may be specifically customized by an operator of the federation chain, and the publisher node device with the largest number of user credit records published in the current billing period is elected as a billing node to perform consensus processing on the candidate blocks based on the data amount of the user credit records published in the current billing period by each merchant node device.
When the method is realized, the merchant node equipment can firstly determine the publisher node equipment corresponding to the collected user credit records when the merchant node equipment initiates the consensus processing of the candidate blocks; for example, the device identification of the publisher node device may be added to a transaction that carries a user credit record; then, the quantity of the credit records of the users issued by each issuer node equipment in the current billing period can be counted; finally, the publisher node device that has the greatest number of subscriber credit records published during the current billing period may be determined to be the billing node device.
In practical application, there may be some repeated records already stored in the distributed database of the federation chain in the user credit records issued by the node devices in the federation chain, in this case, there may be inaccurate problems with the accounting nodes identified by the above-mentioned consensus algorithm; for example, some malicious node devices may obtain the accounting rights by issuing a large number of duplicate records; for this case, such malicious node devices may be elected as billing nodes according to the consensus algorithm described above.
Based on this, in one embodiment shown, in the consensus algorithm described above, the number of user credit records that each publisher node device published in the current billing period may be declared as the number of user credit records that each publisher node device published in the current billing period and there are no corresponding duplicate records in the distributed database of the federation chain.
In this case, when the merchant node device counts the number of user credit records issued by each issuer node device in the current billing period, a query may be initiated to the distributed database of the federation chain to determine whether repeated records exist in the distributed database of the federation chain for the user credit records issued by each issuer node device;
for example, in implementation, it may be determined whether a user credit record has been included in a block of a blockchain by calculating a hash value of the user credit record to be queried, locating a block containing the user credit record based on the hash value, and then traversing the hash value of the user credit record in the Merkle tree of the located block.
Further, the merchant node device may remove the user credit records with duplicate records in the federation chain from the candidate block, count the number of user credit records that are issued by each issuer node device in the current billing period and have no corresponding duplicate records in the distributed database of the federation chain, and determine, as the billing node device, the issuer node device with the largest number of user credit records issued in the current billing period based on the consensus algorithm.
In this way, some malicious node devices can be avoided, and the problem of accounting rights can be obtained by issuing a large number of duplicate records.
Of course, the algorithm logic in the consensus algorithm may be, besides the above description, selecting the publisher node device with the largest number of user credit records published in the current billing period as the billing node, in practical application, also may be other forms of algorithm logic customized by the operator of the federation chain; for example, selecting the merchant node device with the highest quality and highest release speed of the user credit records released in the current billing period as the billing node; alternatively, the specific nodes in the node devices may be designated as billing nodes by the operator of the federation chain based on certain rules (e.g., in a certain order), which are not listed in this specification.
With continued reference to fig. 3, if the merchant node device is ultimately determined to be an accounting node, the candidate block generated by the merchant node device passes through the consensus, and the merchant node device may broadcast the candidate block in the coalition chain as the latest block. Each node device that receives the latest block can initiate accounting based on the latest block, respectively, and link the latest block with the history block, and then add the latest block to the distributed data of the alliance chain for permanent storage.
In this specification, since merchants that are members of the federation may correspond to different merchant types, respectively; for example, services offered by various merchants joining a federation chain may be affiliated with different industries; in the credit closed-loop service, a certain difference may exist in credit evaluation systems of different merchants; thus, in one embodiment, the operator of the coalition chain may divide the coalition chain into a main chain and sub-chains anchored to the main chain that correspond to different merchant types, respectively, based on the specific type of merchant that is a member of the coalition.
For example, taking the example that the merchants joining the chain of alliances include chain hotels, supermarkets, and shared product service providers as the merchants, the node devices of the chain hotels, supermarkets, and shared product service providers can be divided into different sub-chains to anchor with the main chain.
The main chain and the sub-chain in the alliance chain can be completely the same in operation mode, and the issued user credit records in the sub-chain can be added into the main chain in the form of blocks after being summarized in the same mode.
In one aspect, for merchant node devices in a sub-chain, after collecting user credit records that are broadcast by each node device in the sub-chain for distribution to the sub-chain and are jointly verified by each node device in the sub-chain in a current billing period, a candidate block may be created based on the collected user credit records, and after being determined as a billing node, the candidate block may be distributed to the sub-chain as a latest block broadcast, added to a distributed database of the sub-chain, or may be distributed to the main chain, and added to the main chain.
On the other hand, for merchant node devices in the backbone, after collecting user credit records that are broadcast to the backbone by the node devices in the backbone and each sub-chain for the current billing period and that are collectively verified by the node devices in the backbone (i.e., verifying the user credit records that are broadcast in the sub-chain by the node devices in the backbone), a candidate block may be created based on the collected user credit records and, after being determined as a billing node, the candidate block may be broadcast to the backbone for incorporation into the backbone.
When user credit records issued by merchant node equipment are successfully recorded and stored in a distributed database of a alliance chain, each merchant node equipment can complete on-line or off-line operation of credit closed-loop service by inquiring the user credit records in the alliance chain, sharing the user credit records issued by other merchant node equipment and using the recorded and stored user credit records in the alliance chain;
for example, the merchant node devices can perform joint prompt payment, joint punishment and joint excitation on the user based on the user credit records recorded and stored in the alliance chain, so as to jointly monitor and promote the positive performance of the user, and realize business linkage among the same industry and across industries. For example, after the multiple merchants acquire the credit records of the users newly recorded in the alliance chain, the merchants can collect the payment, punish the punishment, the incentive and the like for the users based on the channels of the users respectively reached.
In this specification, the federation chain described above may specifically also incorporate a billing rewards mechanism. The accounting rewards mechanism refers to a node device participating in accounting, and can obtain a reward distributed by a alliance chain.
The node devices participating in accounting specifically may include node devices that obtain accounting rights, or may include all node devices that successfully record user credit records in the federation chain.
In one embodiment shown, if a merchant node device in the federation chain is determined to be an accounting node, a preset number of virtual resources generated by the federation chain may be obtained, and then the obtained virtual resources are issued to an account address corresponding to the merchant node device for holding.
In another embodiment shown, if the user credit record issued by the merchant node device in the federation chain is finally successfully recorded and stored in the distributed database of the federation chain (i.e., the node device is not an accounting node, the user credit record issued by the node device is successfully recorded in the federation chain by the accounting node), a preset number of virtual resources generated by the federation chain can be acquired, and then the acquired virtual resources are issued to an account address corresponding to the merchant node device for holding.
The alliance chain can be automatically generated by merchant node equipment participating in accounting based on an operating algorithm when generating virtual resources, or can be generated by node equipment appointed in the alliance chain, and then unified issuing is carried out; for example, an authoritative node device or a central node device may be designated among the node devices in the federation chain that is responsible for generating and issuing virtual resources as billing rewards for each merchant node device involved in billing.
The specific type of the virtual resource is not particularly limited in the present specification; for example, in practical applications, the virtual resource may be a point, or other form of virtual reward similar to a point.
In the present specification, the virtual resource is specifically used to obtain the usage rights of the user credit records recorded and stored in the distributed database of the federation chain. For node devices in the federated chain, if it is desired to use user credit records already in the distributed database stored in the federated chain, then a certain amount of virtual resources need to be "consumed".
In implementation, the operator of the federated chain may define in the federated chain the number of virtual resources to be "consumed" when using the user credit records in the federated chain.
In one embodiment shown, taking the virtual resource as an example, the operator of the federation chain may issue in advance in the federation chain an intelligent contract related to user credit record queries, and declare in the intelligent contract the number of virtual resources to "consume" when querying and using the user credit records in the federation chain. Meanwhile, virtual resource deduction logic related to the credit record use of the user can be declared in the intelligent contract; for example, the logic may be such that upon receipt of a data query request for user credit records in a distributed database, a certain amount of virtual resources may be "deducted" from the account address of the querying party based on the number of user credit records that need to be queried.
When a merchant needs to use the user credit records recorded and stored in the alliance chain, a data query request (transaction) can be initiated to the distributed database of the alliance chain through merchant node equipment, after the merchant node equipment receives the data query request, the merchant node equipment can respond to the data query request and call the intelligent contract, and the amount of points to be consumed in the query is calculated based on the amount of points to be consumed and the amount of the user credit records required to be queried at the time when the user credit records in the alliance chain are used in the intelligent contract, and then the corresponding amount of points are deducted from account addresses corresponding to the merchant node equipment. Of course, if the account address corresponding to the merchant node device is insufficient in the amount of points, the merchant node device may send a prompt to the user that the query failed.
In this way, only merchant node equipment participating in billing can acquire billing rewards of the alliance chain, so that each merchant can be encouraged to share user credit records generated by online or offline business to other merchants by publishing the user credit records to the alliance chain, and the use authority of the user credit records recorded and stored in the alliance chain can be inclined to the merchants participating in billing; and meanwhile, the threshold of data query and use in the alliance chain can be improved, and some merchants which do not participate in accounting can be limited, or non-merchant users accessing the alliance chain can be used for acquiring and using the user credit records shared by all merchants.
As can be seen from the above embodiments, on the one hand, since the blockchain has historical traceability and non-tamper-ability, user credit records generated over a period of time can be truly recorded on the blockchain in this way, and all user credit records can be traced back on the blockchain; moreover, as the user credit records are verified and maintained by all the node devices together, and the tampering of the user credit records is required to be performed, most of the node devices are required to be controlled, so that the fairness of the user credit records can be ensured;
On the other hand, because the user credit records generated by each node device in the blockchain are shared, each node device can acquire the user credit records issued by other node devices by inquiring on the chain, so that a credit closed loop can be not concentrated on one node device, and each node device can share and monitor each other; in addition, when the credit closed-loop service is deployed, channels reaching users are correspondingly increased, and a plurality of node devices can jointly monitor and promote the positive performance of the users by using the credit records of the users on a chain to jointly collect, jointly punish and abstinence, jointly motivate the users and the like.
