Detailed Description

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

An embodiment of the present application provides a blockchain-based rule determination method, and in a first embodiment of the blockchain-based rule determination method of the present application, referring to fig. 1, the method includes:

step S10, a first business rule corresponding to business data determined by a plurality of business parties is obtained, wherein a block chain is built among the business parties, and the first business rule is selected from a sharing rule set on the block chain;

step S20, based on the first business rule, carrying out rule judgment on the business data, and calculating to obtain a sub-rule judgment result;

and step S30, calculating the sub rule judgment result to obtain a total rule judgment result, wherein the total rule judgment result is obtained by commonly executing rule judgment by a plurality of service parties.

The present embodiment aims at: and establishing a blockchain among a plurality of business parties for processing the business, establishing connection among the business parties, and uploading sub-rule judgment results of the business parties to the blockchain through sharing a rule set to enable the calculation process and the calculation result of the business parties to be disclosed and transparent, thereby increasing the trust degree among the business parties.

The method comprises the following specific steps:

as one example, the blockchain-based rule determination method may be applied to a blockchain-based rule determination apparatus belonging to a blockchain-based rule determination system belonging to a blockchain-based rule determination device.

As an example, a business party may be a company, organization, institution, bank, institution or the like.

As an example, when a service is processed or a result of a transaction is determined among a plurality of service parties, corresponding rules are needed to determine service data, so as to obtain a service processing result, for example, when a user or a company applies for a credit card, the user needs to initiate handling the credit card service, the system determines the qualification of the user according to the uploaded user information, the determining process needs to set rules in advance, for example, the age of the user must be 18 years old to apply, if the condition is not met, the qualification of the user is not met, and then the subsequent service processing cannot be performed.

As an example, the above example is only a simple unilateral decision process, in the rule decision process, a plurality of service parties are often involved, each service party needs to perform a corresponding rule decision process, each service party uploads the rule decision result obtained by calculation to other companies, and after the rule decision result is checked by other service parties or companies, the subsequent service processing is completed.

As an example, the service data may be a service type, a service name, a service dynamic state, information related to related services, or the like, the service data may also be private data of a service party, or shared data commonly monitored by a plurality of service parties, and when the service data is the shared data, a rule determination process may be more transparent.

As one example, blockchains may be public blockchains, private blockchains, and federated blockchains, which are generally considered semi-decentralized (Consortium Block Chains). Designating a plurality of preselected nodes as billing people or managers from within a certain group, the generation of each block is decided jointly by all preselected nodes (the preselected nodes participate in the consensus process), other access nodes can participate in the transaction, but the other access nodes can participate in the transaction, but do not account for the transaction (are in essence, but rather are distributed billing, how many of the preselected nodes decide how the billing people of each block become the main risk points of the blockchain), and other anyone can conduct a limited query through the open API of the blockchain, which in this embodiment is elaborated by taking a alliance blockchain as an example.

As an example, a blockchain may be defined as a chain composed of a plurality of blocks, and the blockchain is built among a plurality of service parties, so that the blockchain is stored in servers corresponding to the service parties, where the blockchain is beneficial in that one server in the whole system can work, the whole blockchain is safe, and the server where each service party is located is a node in the blockchain, and the biggest advantage of the blockchain is that: the data is difficult to tamper and decentralize, and the two characteristics can ensure that the information recorded by the blockchain is more real and reliable, and can help solve the problem of low trust of people.

Before the step of obtaining the first service rule corresponding to the service data determined by the plurality of service parties, the method comprises the following steps:

step A1, determining rule parameters of a rule to be used according to the service name corresponding to the service data;

as an example, a required business rule may be determined according to a business name and a business stage, to obtain a rule parameter thereof, and then, according to the rule parameter, a corresponding business rule is selected from the shared rule set as a target business rule.

As an example, the rule parameter may be a rule number, a decision parameter, a request reference number, etc., for example, a rule number C1 of the invoked rule, the decision parameter is param=2, the request reference number busnbrxx1, and when the rule parameter is determined, the corresponding rule may be selected.

As one example, for the determination of business rules, the determination may be made by querying a business name-business stage and rule parameter relationship table. The service name-service stage and rule parameter relation table can be edited in advance by related operation and maintenance personnel, and is updated continuously along with the addition of various new services and rules in the service processing process.

And step A2, selecting a first business rule corresponding to the business data from the shared rule set according to the rule parameters.

As an example, the business rules in the shared rule set correspond to one rule parameter respectively, and the corresponding business rules can be accurately extracted according to the rule parameters.

Wherein the rule parameters comprise business rule identifications;

step B1, inquiring whether corresponding business rules exist in the sharing rule set according to the business rule identification;

as one example, the shared rule set is specifically a combination of rules uploaded onto the blockchain, i.e., on-link contract rules.

As an example, an on-chain contract rule is an uploaded rule on a blockchain, and the rule used in the whole rule invoking process may be an on-chain contract rule or an off-chain normal rule.

As an example, when selecting a corresponding business rule from the shared rule set, it is required to first determine whether the corresponding business rule exists in the shared rule set, and determine a subsequent execution step according to the corresponding existence/nonexistence result.

Step B2, if the service rule corresponding to the service data exists in the shared rule set, taking the service rule corresponding to the service data as a first service rule;

as an example, when the service rule corresponding to the service data exists in the shared rule set, the corresponding service rule is directly selected as the first service rule.

And step B3, if the service rules corresponding to the service data do not exist in the shared rule set, receiving the first service rules uploaded by the service parties according to the permission instructions of the service parties.

As an example, when the service rule corresponding to the service data does not exist in the shared rule set, a new service rule needs to be uploaded, and before the service rule is uploaded, unified permission of each service party needs to be obtained due to the characteristic of the blockchain, so that the rule uploading can be completed.

As one example, after receiving the permission instructions of the plurality of business parties, the corresponding first business rule is uploaded to the blockchain.

As an example, the first business rule may be a business rule corresponding to business data, or may be a part of a business rule corresponding to business data, and when the situation belongs to the latter, the business rule corresponding to business data is obtained by combining the first business rule with an existing on-link contract rule.

As an example, the uploaded first business rule may be a business party that currently performs rule determination, or may be another business party, which is not limited in particular.

As an example, a parent-child rule relationship is constructed by hierarchically combining rules such that subsequently released new rules can be combined by all of the released rules.

As an example, the business rules are described by an expression language, which is a pluggable program language configured by a user or manager, and the expression language is used for parsing the rules.

As an example, after the combination rule is obtained, the new combination rule is used as the service rule corresponding to the service data, and further, the judgment of the service data is completed.

The step of receiving the first business rule uploaded by the business party according to the permission instructions of the business parties comprises the following steps:

step C1, an uploading request is sent to a plurality of business parties of a block chain, and an allowing instruction fed back by the business parties is received;

and step C2, receiving a first business rule uploaded by the business party according to the permission instruction.

As an example, before uploading a first business rule to a blockchain, an upload request needs to be sent to multiple business parties of the blockchain, and when the multiple business parties agree to the upload request, a new rule can be uploaded for the blockchain.

As an example, the required rule instructions are uploaded to the blockchain according to the allow instructions, thereby facilitating subsequent combination with on-chain contract rules or direct invocation.

as an example, a rule set that is commonly determined by all business parties/trust domains of a shared rule set is recorded in the system in which the blockchain resides, and each business party can invoke a business rule in the shared rule set through the blockchain.

As an example, the first business rules have corresponding identifiers or numbers, respectively corresponding to different business data, and the first business rule with the corresponding number can be selected according to the type of the business data.

As an example, the rule determining process may be to call a service rule, when the service rule corresponds to an on-link contract, send a request to a corresponding intelligent contract to obtain an automatic response result, and when the service rule corresponds to an ordinary contract, the service party monitors service information on the blockchain, and then uploads the service data to the blockchain after executing the rule determining result.

As an example, the sub-rule determination result may be a rule determination result that is performed by each service party separately according to service data, or may be a determination result obtained by directly performing calculation on the blockchain using an on-chain contract rule, and finally uploading the sub-rule determination result to the blockchain, and further, performing integrated calculation on the sub-rule determination result on the blockchain to obtain a total rule determination result.

As an example, each sub-rule determination result has a corresponding number, in the existing rule determination process, since only each service party independently completes the service determination process and uploads the service determination process to the system, in the service processing process, the source of each processing result/determination result in the service processing process cannot be traced back well, and the source of the determination result can be traced back better by numbering the sub-rule determination result.

As an example, not only the sub-rule determination result has a number, but also the corresponding business rule has a corresponding number, and the number of the business rule is for convenience of user selection and identification.

As an example, by executing different rule judging processes on different types of business rules and uploading the rule judging processes to the blockchain, the business party can check the rule judging processes corresponding to each business party, the flow is traceable and can not be tampered, and the credibility of cooperation judgment among multiple parties is improved.

As an example, in the process of interaction of rule determination results of a plurality of service parties, each service party performs individual calculation, and then calculates the calculation result of each service party according to a predetermined formula, thereby obtaining a corresponding service processing result.

The step of calculating the sub rule judgment result to obtain a total rule judgment result comprises the following steps:

and S31, calculating the sub rule judgment result according to the preset rule expression of the blockchain, and outputting a total rule judgment result.

As an example, the preset rule expression may be an expression calculated on the sub-rule determination result according to a contract method.

As an example, the contract is specifically defined among a plurality of service parties, and the sub-rule determination result is processed through the contracted contract content to obtain a corresponding rule determination result.

As an example, the overall rule determination result is a result of a combined action after rule determination by a plurality of service parties, respectively.

As an example, the rule determining method based on the blockchain is also applied to a rule determining system based on the blockchain, and a schematic diagram of the rule determining system based on the blockchain is shown in fig. 4, wherein a rule management module is used for maintaining rules on a chain, and each party uses identity on the chain to call the rule management module, upload and release new rules or update and delete rules under the authority; the rule logic execution module is mainly responsible for analyzing and executing rules, and calculates the total result according to the execution result of each sub-rule and the relation among all sub-rules; the rule contract module is used for managing rules of contract types.

Further, based on the first embodiment of the present application, another embodiment of the present application is provided, in which, referring to fig. 2, the first business rule includes an on-link contract rule and an off-link normal rule;

step S201, if the first business rule is an on-link contract rule, performing contract call on the business data according to the on-link contract rule, and calculating to obtain the sub-rule judgment result;

as one example, an on-link contract rule is specifically a business rule uploaded to a blockchain, where the on-link contract rule follows the calling style of an intelligent contract.

As an example, the contract call is a call process executed by the execution process and the processing logic of the intelligent contract, and the contract call has the advantages of higher calculation speed, transparent and safe calculation process and corresponding rule determination process.

As an example, after making a contract call, the calculated sub-rule determination result is uploaded to a blockchain.

Step S202, if the service rule is an out-of-chain common rule, based on the service party, carrying out rule judgment on the service data according to the out-of-chain common rule, and calculating to obtain a sub-rule judgment result;

as an example, the out-of-chain normal rule is a business rule used when each business party performs rule determination by itself, and the out-of-chain normal rule is not uploaded to the blockchain.

As an example, when the service rule used is an out-of-chain normal rule, the service party completes the calculation process, and then uploads the obtained sub-rule determination result to the blockchain, at this time, the rule determination process executed by the service party is not disclosed, and other service parties can see the sub-rule determination result obtained by the current service party.

As an example, when using out-of-chain common rules, each business party may also share a set of rules that the business party itself uses, which is uploaded to the blockchain by the business party after soliciting consent from the corresponding business party.

Step S203, receiving a sub-rule determination result executed by the service party corresponding to the first service rule.

As an example, after the business party corresponding to the first business rule is executed to complete the rule determination, the obtained sub-rule determination result is uploaded to the blockchain, so that the rule determination result of each business party is publicly transparent.

In this embodiment, rule determination of each service party is performed by on-link contract rules and off-link common rules, so that the privacy of the service party is protected, and disclosure of each rule determination result or rule determination process is ensured.

Further, based on the first embodiment and the second embodiment of the present application, another embodiment of the present application is provided, in this embodiment, service rules in the shared rule set may be freely combined, and when no service rule corresponding to service data exists in the shared rule set, a plurality of service rules are combined, and the combined service rule is used as a first service rule corresponding to rule determination.

As an example, the rule determining process may be performed by a single rule or may be performed by combining a plurality of rules, so as to obtain a corresponding rule determining result.

As an example, when the service rule corresponding to the service data does not exist in the shared rule set, and at this time, the required first service rule may be obtained by combining other service rules in the shared rule set, then other service rules are combined, and the combined rule is used as a service rule required for executing the rule determination, for example, the a service party needs the a rule to execute the service determination, and the b rule and the c rule in the shared rule set may be combined to obtain the a rule, and then the a service party selects the a rule to execute the rule determination.

As an example, according to the business rules in the shared rule set, the combination rules are generated, new business rules do not need to be uploaded, other redundant operations are reduced, and meanwhile, other business parties can monitor the combination rules executed by the business party currently executing the rule judgment, so that the rule judgment process is public and transparent.

In this embodiment, the rules required by the service party are obtained by combining the rules in the shared service rule, so that the service party is prevented from uploading new rules, redundant manual operation is reduced, and meanwhile, the rule judging process can be monitored, so that the reliability of cooperation judgment among multiple parties is improved.
