How To Use Blockchain in Korea for Pandemic Era

Blockchain is designed so that one data is simultaneously recorded on multiple distributed servers, and can only be accessed and entered through a verification and consensus system between them. Through this, it is possible to prevent thorough activation and manipulation of records by linking all vaccine-related data to the blockchain from the beginning of production and distribution.

In addition, in the case of vaccines, as many people as possible must be vaccinated normally, the effect of collective immunity can be expected, so transparency in distribution management should be guaranteed more than ever. Incidentally, the introduction of blockchain into the distribution network allows multiple verification procedures to be handled by software. This also has the advantage of preventing mistakes caused by direct human verification and saving related labor costs.

In addition to distribution, blockchain can help manage and track vaccination records. Experts predict that in 2021, as the distribution of the Covid19 vaccine will accelerate, proving 'whether or not you have been vaccinated' can be a social issue.

Even at this time, if a public system that can be easily carried by mobile than a simple paper certificate that can be forged and can transparently prove identity authentication and vaccination record management through a block chain is implemented, problems arising from such disputes can be minimized. 

Also, unlike in the past, even if it is assumed that there is a problem in the future with a vaccine that has started distribution without going through sufficient procedures, using the smart contract system of the blockchain will find the vaccine inoculum in the most accurate and quickest time and notify the problem Will be possible. As such, blockchain is expected to become a technology that contributes to reducing unnecessary social costs in each field in the post-pandemic era beyond the with pandemic era.
