Vaccine management method based on block chain and storage medium

Abstract

The invention discloses a vaccine management method based on a block chain. The block chain is composed of a plurality of block nodes, each block node is divided into a main block and an auxiliary block, the main blocks and the auxiliary blocks are in one-to-one correspondence, the method comprises the steps that first vaccine information of all vaccines of a current node is stored in the auxiliary blocks, and the first vaccine information at least comprises temperature record information of the vaccines; obtaining temperature qualification results of all vaccines according to the temperaturerecord information; and mapping the temperature qualification result obtained in the auxiliary block to the main block, storing second vaccine information of all vaccines of the current node in the main block, and uploading the main block to a block chain, the second vaccine information at least comprising a vaccine traceability code and a temperature qualification result of the current node. According to the invention, excessive data redundancy of the block chain is avoided, and the operation efficiency of the block chain is improved.

Description

technical field [0001] The present invention relates to the technical field of block chain, in particular to a vaccine management method and storage medium based on block chain. Background technique [0002] Vaccines play an extremely important role in the prevention of diseases. Due to the particularity of vaccines, the use of vaccines will be greatly restricted. Once used improperly, it may cause irreparable consequences. Therefore, the control of vaccines has become very important. Vaccines must be stored, transported, and used in strict accordance with expensive temperature conditions during the process from the manufacturer to the consumer. Therefore, the security and transparency of information such as vaccine storage and transportation are of great importance to enterprises, regulatory agencies, and consumers. meaning. [0003] In the existing technology, the use of traditional regulatory means to manage vaccines inevitably has the following defects: different datab...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the use of traditional regulatory means to manage vaccines inevitably has the following defects: different databases may store the information of the same vaccine, resulting in high data redundancy, and different central institutions manage their own vaccine data information , which is not conducive to data sharing between institutions, users cannot independently verify the correctness of the data, and if someone maliciously modifies vaccine information through illegal channels, it may not be traceable, which brings difficulties to vaccine management

However, in the storage and management of vaccine information, each management agency must record the temperature of the vaccine every day. A large amount of recorded data causes redundancy of blockchain node data, resulting in slower query speed for vaccine information, resulting in the entire Inefficient operation of the blockchain system
