Invoice management system and method based on block chain technology

Abstract

The invention provides an invoice management system and method based on a block chain technology, and the system and method form a block head through a tax bureau and related management departments, which is used for providing data led from a hash value of a parent block, determining the overall encryption difficulty and timestamp, and forming root data in invoice data. Each enterprise unit capable of executing electronic invoice issuing forms a block body, and the block body is composed of the number of invoices, invoice flow, a block head, a block size and a magic number. Therefore, a business contract and an account book are formed, and a final invoice management system is formed. The whole invoice process is completely digitized and shared, and a traditional data island is broken through. The data can be prevented from being tampered, and the invoices are prevented from being repeatedly reimbursed or maliciously reimbursed during reimbursement.

Description

technical field [0001] The present invention relates to the technical field related to taxation, in particular to the technical field related to electronic invoices, and in particular to an invoice management system and method based on blockchain technology. [0002] technical background [0003] Traditional electronic invoices are developed and constructed in a centralized manner or entrusted to a third party. As the number of these platforms continues to increase, the data sharing and transfer between these self-built platforms and third-party platforms has become a major obstacle. With the process of Internetization, the previous technical means and management methods can no longer meet the needs of online and offline transactions. [0004] With the development of blockchain technology, electronic invoices are added to the blockchain. It uses the decentralized consensus mechanism of blockchain technology to maintain a complete, distributed, and non-tamperable ledger databa...
