The COVID-19 pandemic has suddenly arisen as a global health emergency requiring concerted international action. Governments are working to stop the virus from spreading and health organizations rushed to create vaccines that would protect people. Reduce Covid-19 morbidity, reduce strain on healthcare systems, and let economies to expand. The Vaccine Certificate has been adopted as a way forward after the COVID-19 vaccination to assist authorities in formulating policies by restricting cross-border travel. In this work, we employ blockchain technology to construct a safe and verifiable vaccination certificate, which alleviates substantial privacy concerns and eliminates the need for third parties to maintain trust and control the user’s data. Different modern technologies, such as smart contracts, are used in our approach.
