Abstract

The invention discloses a data tracing method and device based on a block chain, computer equipment and a storage medium. The method comprises the steps of uploading operation data of each process node in a bill circulation process and storing the operation data into a basic database; and performing consensus verification on the operation data of each process node to obtain an identification code,storing the operation data into a block generation block hash, and storing the operation data into a cloud database. According to the invention, the block corresponding to the transaction code duringuplink can be inquired through the transaction code, and the corresponding data is acquired from the block; the corresponding block hash can be traced and acquired through the identification code, the block hash value of the previous process node is acquired from the block hash of the current process node, the block hash of the previous process node is acquired according to the block hash value,and the whole process tracing of the bill is realized through repeated tracing, so that the step-by-step tracing from the bottom layer data is realized, and the tracing efficiency is improved. And thesecurity and authenticity of the data are improved.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a data traceability method, device, computer equipment and storage medium based on block chains. Background technique [0002] The current enterprise resource planning (Enterprise Resource Planning, referred to as ERP system) in the decoration and construction industry uses traditional databases for storage, and can only trace the upper-level logic from the logic of the ERP system. Every step of the EPR system requires database operations, but the database The association relationship is all associated by the EPR business logic, and the steps cannot be traced from the underlying data, and the security and authenticity of the data need to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a blockchain-based data traceability method, device, computer equipment, and storage medium, aiming to solve the problem of insuffic...
