Data processing method and device based on blockchain network and storage medium

Abstract

The embodiment of the invention discloses a data processing method and device based on a block chain network and a storage medium. The blockchain network comprises a plurality of nodes. The data processing method based on the block chain network comprises the following steps that a node receives an invoicing request submitted by a client running on the user terminal, in response to the invoicing request, invoicing number segments are allocated by calling an intelligent contract; and the smart contract receives the distributed invoice number segment, broadcasts the distributed invoice number segment to other nodes in the plurality of nodes in the blockchain, and after the smart contract detects that the other nodes pass the consensus of the distributed invoice number segment, the node issues an invoice according to the distributed invoice number segment and returns the issued invoice to the client on the user terminal. By adopting the data processing mode based on the block chain network, invoicing can be conveniently carried out through the block chain technology, and the invoicing cost of enterprise operation is reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data processing method, device and storage medium based on a block chain network. Background technique [0002] The tax-calculating cash machine is a cash register with a tax-calculating function that is legally serious and indestructible. It is not only a right-hand man for the operation and management of commercial enterprises, but also a law enforcement representative for tax officers to collect sales data in the store. Enterprises need to purchase a tax cash machine to issue invoices, which increases the business billing cost of the enterprise. Moreover, if the tax cash machine breaks down, the invoicing behavior cannot be performed, and the convenience of invoicing is low. It can be seen that how to provide a convenient and low-cost billing method that replaces tax control equipment has become an urgent problem to be solved. Contents of the invention [0003] ...
