Detailed Description
The most widely applied electronic invoice in the electronic certificate is an accounting certificate between a merchant and a consumer, and in reality, the steps of the business process of the electronic certificate are as follows: the method comprises the steps that a merchant evaluates the self condition according to the requirement, applies for an electronic invoice to a tax bureau, the tax bureau adopts uniform coding and encryption to the electronic invoice in an electronic invoice system, and issues the electronic invoice to an enterprise, and when the enterprise uses the system, information such as a company name, a taxpayer identification number and the like needs to be input. When a consumer needs an invoice, a merchant applies an electronic invoice system to issue the invoice to the consumer, the electronic invoice has time information, transaction information, a signature and the like, the uniqueness and reliability of the electronic certificate are guaranteed, and the issued invoice is transmitted to a tax bureau and is validated after being audited; the electronic certificate is stored mainly by a financial system, an ERP system and a database of a merchant; the invoice reimbursement is mainly realized by scanning a two-dimensional code on the invoice to identify the invoice, and after the invoice information is confirmed, a financial department can reimburse the invoice;
as shown in fig. 1, an application platform of an electronic certificate based on a block chain combines the electronic certificate with the block chain, builds an application platform of the electronic certificate based on the block chain, and gets through data flow between the platforms, and the main goals to be achieved include the following aspects:
the first aspect is as follows: and building a decentralized electronic certificate application platform based on the block chain. On the basis of the block chain, all nodes are accessed into the block chain through a P2P network, and all services of an application platform are realized by adopting cloud computing;
the second aspect is that: and realizing the information sharing of the electronic certificate resource. The electronic certificates are all accessed into the system under the heading of state organs and become nodes of the block chain. Data sharing is realized, the barrier of the platform is opened, and data circulation is realized;
the third aspect is that: the platform realizes the wide application of circulation, verification, account entry and filing of the electronic certificate. The application platform can realize a one-line service of the electronic certificate, and platform solutions are provided from verification, posting to filing, so that convenience is brought to a user, and the efficiency of processing the electronic certificate by an enterprise is high;
aspect four: improving the informatization level of state organs. The application platform solves the detail problem, and the state organ only needs to manage the platform, thereby saving time and labor and improving the work efficiency of the state organ.
