Fighting COVID-19 and helping economy reopen by using blockchain technology

This paper introduced a best practice on personal health data management on blockchain technology. When the global community is dealing with COVID-19 pandemic and economy reopen strategy, a solid solution is needed to cover various aspects: health data collection and monitoring, data privacy control, immutable data record, global identity and cross region collaboration. By using distributed ledger technology, decentralized identity, verifiable credential, and distributed storage, we built the GreenPass solution to address COVID-19 mitigation and economy reopen issues at the community level. We also envision GreenPass solution as the personal data vault with data ownership and permission management, as a green passport for a person to the future of "data as a personal property right" new world.
