Abstract

This application provides a blockchain-based information acquisition method, which includes: receiving the billing request submitted by the first participating account, sending the transaction identification and transaction information in the billing request to the consensus node; In the case that the consensus confirmation message satisfies the preset consensus strategy, the first ticket information is generated according to the billing request submitted by the first participating account, the ticket block is generated according to the first ticket information, and the ticket block is uploaded to the blockchain network Middle; determine the bill verification node corresponding to the second participating account according to the identifier of the second participating account; send the address of the bill block to the bill verification node. The implementation of the present application enables the bill verification node to read the first bill information in real time according to the address of the bill block when receiving the business write-off request.

Description

technical field [0001] The present application relates to the technical field of blockchain, in particular to a blockchain-based information acquisition method, device, device, and storage medium. Background technique [0002] With the development of modern industry and commerce, business entities such as enterprises and companies often need to carry out cross-regional business activities, and because the tax systems of various regions are independent of each other, especially the lack of communication and exchange of tax data at the cross-provincial level, It is usually difficult for business entities to conduct timely and effective invoice verification for cross-regional business activities. Contents of the invention [0003] This application provides a blockchain-based information acquisition method, so that the bill verification node can read the bill information in real time when receiving a business write-off request. [0004] On the one hand, the embodiment of the ...
