Abstract

The invention relates to a blockchain-based data record traceability system and method. The system includes: a dynamic code generation module, a blockchain verification and on-chain module, a non-relational database and a traceability query module; the dynamic code generation module is used to generate a dynamic code; the dynamic code is used to code each log item ; The block chain verification and chaining module is used to verify the log after the identification, and after the verification is passed, the chain is carried out; and the block chain after the chain is saved to a non-relational database; the non-relational database is respectively It is connected with the blockchain verification and uplink module and the traceability query module; the traceability query module is used to perform traceability query on the blockchain stored in the non-relational database. The invention realizes the traceability function of the data record and ensures the credibility and reliability of the record.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a data record traceability system and method based on block chains. 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] However, due to the security of the blockchain, it is difficult to understand the traceability of the data records on the blockchain, and it is impossible to realize the traceability of the data records on the chain. Contents of the invention [0004] The purpose of the present invention is to provide a blockcha...
