Abstract

Since COVID19 virus has been occured, variety steps of the quarantine guidelines were enacted. In step 2.5, eating in a cafe was prohibited and only takeout was permitted, but the government has changed several rules. So now people can have a dissert or coffee in the cafe. Though the government adviced available staying time as 1 hour, it is not obeyed often except superstore, and even the management depends on handwriting. In this paper, we implemented a blockchain system to use for this case. This system is implemented with using hyperledger fabric, the blockchain framework which is made by IBM. For a test, 1 organization is in the system and chaincode is installed to the organization to run the system. We expect the certain effect to the quarantine via this system. Moreover, we will develop an application by using this system as a backend.

COVID-19 바이러스가 발생한 이래로 방역수칙에 관한 다양한 단계가 제정되었다. 1~3단계 중 2.5단계의 경우 카페 매장 내 취식은 불가하며 오직 테이크 아웃만이 허용되었으나, 최근 정부에서 조치사항을 변경하여 매장 내에서의 취식이 가능하게 되었다. 하지만 취식 가능 시간은 1시간으로 권고하였으나, 대형 매장을 제외하고서는 잘 이루어지지 않으며 그마저도 수기 위주로 관리가 되고 있다. 본 논문에서는 이에 대해 사용할 수 있는 시스템을 IBM의 프라이빗 블록체인 프레임워크인 하이퍼레저 패브릭을 통해 구현하였다. 이 시스템을 통해 향후 COVID-19에 대한 더 확실한 방역을 기대한다. 또한, 향후 이 시스템을 백엔드로 하여 애플리케이션으로의 개발 또한 진행해볼 것이다.
