Embodiment Construction

[0034] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] In this embodiment, the structure diagram of the distributed weakly centralized electronic invoice system based on multi-chain technology proposed by the present invention is as follows figure 1 shown. The State Administration of Taxation, local taxation bureaus, and enterprises each maintain and manage a sub-chain. For enterprises, the sub-chain maintained and managed can complete the internal invoice guarantee and audit functions of the enterprise. Unit employees or auditors only need to access the sub-chain to achieve Business circulation; for the tax authorities, the sub-chains maintained and managed can complete tax collection and management within the jurisdiction; at the same time, all sub-chains are publicly involved in the information mana...

Abstract

The invention discloses a method for constructing an electronic invoice system based on multi-chain configuration. Under the background of increasing pressure on the computing, storage and information security of the centralized system, the multi-chain technology of the blockchain is used to establish a distributed weakly centralized electronic invoice system that meets the invoice circulation business. The multi-chain configuration overcomes the great pressure and high risk of the centralized storage of massive data in the centralized system, and also overcomes the disadvantages of the slow operation speed of the system based on single-chain technology. Verification and consensus reach speed and system compatibility, suitable for large system integration and large-scale parallel computing. The invention can improve the reliability and security of the electronic invoice system.

Description

technical field [0001] The present invention relates to a method for constructing an electronic invoice system, in particular to a method for constructing an electronic invoice system with a multi-chain configuration of blockchain technology. Background technique [0002] Invoices refer to the business vouchers issued or received by all individuals and units in the process of buying and selling goods, receiving or providing services, and engaging in other business activities. It has an extremely important significance and role in our country's social and economic activities. With the development of information technology and the advent of the information age, convenient and low-cost electronic invoices have gradually been popularized and applied. The "Online Invoice Management Measures" issued by the State Administration of Taxation mentioned that electronic invoices will be promoted nationwide. use. [0003] Compared with traditional paper invoices, electronic invoices ha...
