The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment provides a service processing method based on a block chain, as shown in fig. 1, including the following steps:
and S110, acquiring evaluation results of corresponding service related parties according to the issued service intelligent contract, wherein the service related parties comprise block chains participating in the service and/or block chain link points participating in the service.
Illustratively, the service-related parties may be a block chain participating in the same service and a block link point participating in the service, and the block chain participating in the same service and the block link point participating in the service may be determined according to a published service intelligence contract. The block chain participating in the service can comprise a federation chain, a private chain and a cross-chain network, and the block chain link points participating in the service can be other nodes in the same federation chain as the service publishing node. The evaluation result of each business-related party can be a score, such as any score of 1-10; or the character evaluation results such as "excellent", "good", "poor", and the like. Taking the evaluation result as a score as an example, the score of each service related party can be obtained by scoring the service related party by other service related parties in the historical service in the process that the service related party participates in the historical service; or the initial scores are set according to the initial scale of each business-related party and the assets, for example, the larger the scale of the business-related party is, the more the assets are, the higher the scores are, or the initial scores of the business-related parties are obtained according to the voting numbers of other business-related parties. The embodiment of the present application does not limit the determination method of the evaluation result.
The score can be pre-stored in the local of each service related party, and the obtaining mode can be that the service related party issuing the service intelligent contract obtains the scores of other service related parties through a side chain technology or an agent technology in a cross-chain mode. The method for obtaining the score of each service related party is not limited in this embodiment, and those skilled in the art can determine the score as needed.
Taking the private chain of the loan party, the bank and the guarantee institution as an example, when the loan party applies for a loan to the bank, the bank needs the guarantee institution to guarantee the loan behavior of the loan party, and three guarantee institutions A, B, C are willing to guarantee the loan, at this time, the bank party obtains scores locally stored by the three guarantee parties through a cross-chain technology.
And S120, determining the target business related party according to the evaluation result of each business related party and the preset evaluation rule.
For example, the preset evaluation rule may be set according to the requirement of the service-related party issuing the intelligent contract, and the preset evaluation rule may define, in the form of the intelligent contract, the rating level of other service-related parties required by the service-related party issuing the intelligent contract, and then obtain the target service-related party meeting the requirement of the preset evaluation rule according to the obtained rating of each service-related party and the preset evaluation rule. And if the preset evaluation rule stipulates that the score needs to meet more than 9 points, taking the service related party meeting more than 9 points as the target service related party.
And S130, performing service processing based on the service intelligent contract and the target service related party.
Taking the loan transaction as an example, the bank obtains scores of three security institutions A, B, C, wherein the scores are 70, 80 and 90 respectively, the bank side provides the security institution with the highest score as the target security institution in the evaluation rule of the bank side, and then the security institution C is obtained as the security institution required by the transaction, and then the loan side and the security institution C perform loan transaction processing based on the loan transaction intelligent contract.
According to the service processing method based on the block chain, the scores of all service related parties are obtained before the service is performed, and the service related parties participating in the service are screened according to the scores and the preset selection rules, so that the service risk can be reduced, the data of each block chain participating in value circulation is more real and credible, and the safety of service processing is improved.
As an optional implementation manner of this embodiment, after step S130, the method further includes:
firstly, transaction execution data and/or prediction machine feedback data of each target service related party are obtained.
Illustratively, the transaction execution data of each target service-related party represents transaction execution data, such as fund flow data, service flow data and the like, generated by each target service-related party when executing the service in the service, and the transaction execution data are correlated among the target service-related parties and can mutually verify the data authenticity of each other. The predictive speech machine feedback data represents the comparison result of the service data and the real data in the block chain, for example, if a certain service related party specifies that the petroleum price is 80 dollars, and the real petroleum price obtained according to the predictive speech machine feedback data is 35 dollars, the predictive speech machine feedback data is not real. The transaction execution data of the business-related party may be obtained by obtaining a blockchain ledger of the business-related party and obtaining the transaction execution data according to data information recorded in the blockchain ledger. The acquisition mode of the feedback data of the prediction machine can be obtained by receiving external internet data by the prediction machine.
Secondly, judging whether each target service related party meets a credible condition or not according to service execution data and/or prediction machine feedback data;
for example, the determination manner of whether the transaction execution data meets the trusted condition may be to determine whether the service execution data between the service related parties can be mutually adjudicated by looking up the service execution data of each service related party, for example, in a certain service, the block chain account of one service related party C records that 1000 pieces of money are transferred from the service related party a to the service related party B, when the block chain account of other service related parties passes through the transaction of other parties or the feedback of fund flow and service flow, it is considered that 1000 pieces of money are not transferred from the service related party a to the service related party B, at this time, the other service related parties consider that the service related party C does not meet the trusted condition; when the service execution data of the service related party A is considered to be consistent with the feedback data through the feedback of the fund flow and the service flow of other transaction related parties, the other service related parties consider that the service related party C meets the credible condition.
The judging mode of whether the transaction execution data meets the credible condition can also be that whether the transaction data of the service related party is consistent with the external access data is verified through the data feedback of the prediction machine. For example, in a certain service, the service-related party a says that the oil price is 80 dollars, and when the oil price is actually 35 dollars as verified by the feedback data of the prediction machine subsequently, the rest service-related parties consider that the service-related party a does not meet the credible condition; and when the oil price is actually confirmed to be 80 dollars by the feedback data of the prediction machine subsequently, the rest service related parties consider that the service related party A meets the credible condition.
And then, adjusting the evaluation result of the corresponding target service related party according to the judgment result.
In the service processing method based on the block chain provided by this embodiment, the evaluation result represents the rights of the service-related party in the whole service system block chain, and each service-related party scores other service-related parties according to the service condition of each time, so that the score can be dynamically revised, and the method has a reference value for selecting the subsequent service-related party, thereby further reducing the service risk and improving the service security.
As an optional implementation manner of this embodiment, when the evaluation result is a score, adjusting the score of the corresponding service related party according to the determination result, includes:
when any target service related party does not meet the credibility condition, reducing the score of the corresponding service related party;
illustratively, taking the oil price as an example, the data fed back by the prediction machine verifies that the service execution data of the service related party a does not meet the credibility condition, then the service execution data of the service related party a is considered to be untrustworthy by other service related parties, and each other service related party reduces the score of the service related party a.
And when any target service related party meets the credible condition, increasing the score of the corresponding service related party.
For example, taking the example that the block chain ledger of the business related party C records that the business related party a transfers 1000 pieces of money to the business related party B, when the block chain ledger of the other business related party confirms that the business related party a transfers 1000 pieces of money to the business related party B through the transaction of other parties or the feedback of the fund flow and the business flow, the other business related parties consider that the business execution data of the business related party C is credible, and each other business related party increases the score of the business related party a.
According to the block chain-based service processing method provided by this embodiment, by judging whether the service execution data meets the trusted condition, scores of corresponding service-related parties are increased or decreased, rights and interests of each service-related party in the block chain of the whole service system are dynamically adjusted through a constructed reward and punishment mechanism, the service-related parties execute transactions meeting the trusted condition for many times, the scores are improved, corresponding participation in the block chain of the whole service system is also improved, and thus forward excitation of each service-related party is realized, and the whole system develops towards a healthier direction.
As an optional implementation manner of this embodiment, the method further includes: and storing the obtained scores of the service related parties in a third party block chain.
Illustratively, the third-party block chain does not participate in the service, does not belong to the service-related party, and is only used for storing the scores of the service-related parties, and the scores of the service-related parties can be obtained by reading the data information of the third-party block chain. The mode of storing the score of the service-related party into the third-party blockchain may be to transmit the data of the service-related party blockchain to the third-party blockchain by a chain-crossing technology such as a side chain or a proxy technology.
In the service processing method based on the block chain, the score of the service related party is stored in the third party block chain, and when the score needs to be read or adjusted, the data stored in the third party block chain is directly read, so that convenience in reading and adjusting the score is improved.
