acquiring and transmitting authentication data of a user, and generating and transmitting an external authentication request to an external authentication API according to the authentication data of the user;
Acquiring verification information of an external verification API, and writing verification data in a verification request after verification into a specific database according to the verification information;
Matching the verification data of the user to be written into the application database with the verification data in the specific database, and generating and sending a matching result;
Writing verification data of the user into an application database according to the matching result to finish data writing;
The method for acquiring the verification information of the external verification API and writing the verification data in the verification request of which the verification is completed into the specific database according to the verification information comprises the following steps:
establishing a specific database in the block chain relation database for storing external verification data, and establishing a specific table in the specific database;
and acquiring verification information of the external verification API, and writing verification data in a verification request with verification completed into a specific table in a specific database according to the verification information.
6. The method for implementing a blockchain relational database-based predictor of claim 5, wherein the method for writing the verification data in the verification request after the verification is completed to the specific database according to the verification information comprises the steps of:
Judging whether the verification data of the user passes verification according to the verification information, if so, writing the verification data in the verification request passing verification into a specific database; if not, generating and sending verification failure prompt information.
7. The method for implementing a predictor based on a blockchain relational database according to claim 5, wherein the method for writing the verification data of the user into the application database according to the matching result, and completing the data writing comprises the following steps:
Judging whether the data matching is successful or not according to the matching result, if so, writing the verification data of the user into an application database, and finishing the data writing; if not, generating and transmitting the writing failure information.
8. The method of claim 5, wherein the verification information includes authentication information, authentication results, data authentication information, and data authentication results.
