Vottun, a company that specializes in the certification and traceability of data on the blockchain, has released a digital health passport that could enable employees currently in lockdown to go back to work.

The digital credentials system — known as an ‘Immunity Passport’ — created by Vottun records your immunity status on the blockchain which can easily be checked.

Rohan Hall, Chief Executive Officer (CEO) at Vottun, told Cointelegraph the passport “can be verified at any time using cryptography by any mobile phone that can read a QR code”. Credentials “are securely stored” and “immutable” and the system is as simple as using a mobile boarding pass for a flight.

The technology is currently being rolled out in Spain in conjunction with PwC. In the United States, Vottun reports it has already ”had early conversations” with the CDC and Dr. Anthony Fauci, Director of the National Institute of Allergy and Infectious Diseases.

However the concept itself is controversial, with some likening immunity certificates to German soldiers demanding papers, while residents in China have wondered how else the data might be used.
