Step S304: and storing the credit event and the credit rating of the different block chain nodes to the item affiliate to be evaluated according to the credit event on the block chain nodes with the hash value of the unique identifier of the item affiliate to be evaluated as an index.
Step S305: and calculating a credit evaluation result of the item to be evaluated, which is based on a preset algorithm, according to the credit rating of the item to be evaluated, which is based on the plurality of block link points.
For example, the credit ratings of the item affiliate to be evaluated by the plurality of block link points may be averaged, or a credit evaluation result of the item affiliate to be evaluated may be generated according to a preset weighting model.
Step S40: and responding to the query request of the user, and pushing the credit evaluation result of the tie person of the item to be evaluated to the user.
In this embodiment, the method further includes the step of storing the credit events and credit ratings of the affiliates of the items to be evaluated in the blockchain node. Please refer to fig. 5. The method further comprises steps S501 to S503.
Step S501: and acquiring the credit event of the tie person of the item to be evaluated.
Step S502: and extracting the hash value of the unique identification information of the project system person to be evaluated.
Step S503: and storing the credit event of the item to be evaluated tie person on a block chain node with the hash value of the unique identifier of the item to be evaluated tie person as an index.
In this embodiment, before step S40, referring to fig. 6, the method further includes steps S401 to S402:
step S401: and when receiving a query request, judging whether the credit event of the tie person of the item to be evaluated is updated.
Step S402: and when the credit event of the item affiliate to be evaluated is not updated, pushing the credit evaluation result of the item affiliate to be evaluated, which is pushed last time.
And if the credit event of the item affiliate to be evaluated is not updated, the credit rating of the item affiliate to be evaluated is also not updated, so that the credit rating of the item affiliate to be evaluated generated by the last query is only required to be called and pushed.
In this embodiment, before pushing information to the user, the identity information of the user needs to be determined. Referring to fig. 7, the method further includes steps S601 to S602.
Step S601: acquiring user identity information input by a user;
step S602: and comparing the acquired user identity information with the registered user identity information, and pushing a credit evaluation result of the project affiliate to be evaluated when the acquired user identity information is matched with the registered user identity information.
