A system that uses blockchain technology to realize point bookkeeping

Abstract

The invention discloses a system for realizing points bookkeeping by using block chain technology, which includes an identity identification module, a node screening module, a bill identification module and an access analysis module; identification; the bill identification module is used to identify the uploaded bill certificate; the node screening module selects the block chain access node matching the login terminal according to the preset rules; the present invention utilizes block chain technology to reduce the fraudulent transaction behavior in the account process; the service quality score of the blockchain node is calculated by obtaining the state parameter value and load value of the blockchain node, and the corresponding blockchain service node is selected according to the service quality; through bill identification The module realizes the accuracy and efficiency of bill identification in the blockchain system; the user identification method adopts the real-time verification code and the random number plus "salt" strategy to obtain the security code, which greatly improves the security of user identification.

Description

technical field [0001] The invention belongs to the application field of block chain, relates to a point bookkeeping system, in particular to a system for realizing point bookkeeping by utilizing block chain technology. Background technique [0002] Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "retaining traces throughout the process", "traceable", "open and transparent", and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects. [0003] In the existing technology, both parties to the same transaction conducted by the buyer and the seller keep their own accounts, which leads to the possibility of fraud in the middle, such as false invoicing, over-recording of expenses, and tampering of transaction i...

Problems solved by technology

[0003] In the existing technology, both parties to the same transaction conducted by the buyer and the seller keep their own accounts, which leads to the possibility of fraud in the middle, such as false invoicing, over-recording of expenses, and tampering of transaction items and amounts during bookkeeping; at the same time, the current blockchain There are also certain disadvantages in the point bookkeeping system. During point bookkeeping, it is impossible to effectively identify the identity of the user who logs in to the blockchain system, and it is also impossible to select a matching and good blockchain service node. Blockchain technology cannot identify all kinds of bills and vouchers well; therefore, we propose a system that uses blockchain technology to realize point bookkeeping
