Abstract

The invention discloses a certificate block chain application module based on chain Hash state management, the application module is a specific business logic layer, i.e., an original business system of a certificate issuing mechanism and the like, the application layer system interacts with a platform layer by opening Api, verification of related certificates in a business process and issuing of a business conclusion achievement file are achieved. The application module achieves the functions of issuing processing logic, certificate changing or logout logic, certificate information verification logic and file verification logic. The application module interacts with a platform layer by opening Api, and achieves verification of related certificates in a business process and issuing of business conclusion achievement files (such as certificates).

Description

technical field [0001] The invention relates to a certificate blockchain application module based on Hash state management on the chain, specifically in the technical field of blockchain. Background technique [0002] The main process of the existing electronic license blockchain solution, after the issuer fills in the license name, number, owner, validity period and other face information on the centralized platform, the license information is encrypted and uploaded to the license through on-chain transactions On the chain, the search information composed of the certificate chain, certificate name and number is uploaded to another search chain or off-chain database, and the database saves a data of the owner and search information to facilitate the search of all the holders' certificates. [0003] The certificate holder needs to query the retrieval information of the required certificate through the database of the platform. The retrieval information includes the index of t...
