Blockchain Credentials for COVID-19 Data Management

At the moment, it is difficult for someone to prove that they have tested negative for COVID-19 across borders. Blockchain and DLTs can help transfer and share data efficiently between governments and businesses while ensuring the privacy of the individual. A blockchain-enabled system for COVID-19 tracing could also be thought of as a MVP for a larger effort to build a decentralised system for digital health records which patients can bring with them no matter where they go.
