Blockchain has been invented for years and it gradually become the most important technique in nowadays’ internet era. Blockchain technology has been widely used in various fields, such as finance, trading, logistics, currency, etc. This paper explains and demonstrates the main algorithm and application of the blockchain. Until now, the primary applications of blockchain are mainly focus on the digital currency such as ETH. The value of blockchain, however, is not limited by only the digital currency but all the aspect within the internet. For instance, based on these years’ social concern, the pandemic of COVID-19 is the most worried problem. The application of this paper concentrates on the connection between COVID-19 and blockchain. By relating the technique of blockchain, the security and data tracing of medical supplies have been insured. Moreover, the personal information security is maintained during the process of doing the covid-test and the trajectory of activity.
