Problems solved by technology
[0003] (1) The electronic invoice data issued by the taxpayer is aggregated and stored on the third-party platform, and the third-party platform provider can access all the invoice data of users on the platform. The data storage and management standards of the third-party service platform are not standardized, and the electronic invoice data is leaked and leaked. Risk of being exploited
(2) Electronic invoice data transmission, storage and other standards are not standardized
(3) There are many third-party service providers, and different electronic invoice service platforms have different entrances. It is difficult for the recipient to obtain invoices. Taxpayers cannot query and print invoices through a unified query and verification portal.
(4) The State Administration of Taxation does not store PDF format files, which are stored separately by each third-party bottle, and there are information islands
(5) The inspection and download of electronic invoice format files cannot provide an authoritative unified way
(6) Electronic invoice format files have brought new problems to the reimbursement management, account management and archive management of enterprises because of their repeatable copying and resubmitting characteristics.

A blockchain-based electronic invoice system and an implementation method, the method comprising: (S1) applying for registration: the tax bureau generates a private key on the blockchain system according to the needs of taxpaying users, and uses the generated private key to generate a private key. (S2) Return the private key: tax users can query their own invoices according to the address generated by the tax bureau, and perform identity authentication or decryption through the public key and private key; (S3) Invoice purchase: The tax bureau terminal writes the tax payment user's invoice balance into the blockchain system, and returns the invoice balance to the tax payment user terminal; (S4) Invoice issuance: the tax payment user terminal enters the invoice data, and records the entered data. Perform encryption, and then upload the encrypted data to the blockchain system; (S5) Invoice query: query invoice information according to the address and private key of the tax payment client. The invention has the advantages of high mutual trust, data immutability, data traceability, interconnection, distributed storage, decentralization and the like.
Description
Technical field [0001] The present invention relates to the technical field of electronic tax invoice, and more particularly relates to a method implemented in the electronic invoice system based and block chain.
