Many nations around the globe are contemplating how to transition back to the new normalcy of life as the infected cases of COVID-19 continues to decline. One option being considered is to perform contact tracking to maintain the infection transmission under control and prevent another wave of outbreak. Especially given the fact that there are various choices, contact tracing is accessible, but it still has difficulties with privacy protection of users which makes its widespread implementation challenging. Relying on this, a unique architecture for contact tracing is proposed, which employs blockchain as its technology. Personal privacy of users can indeed be preserved by also providing the general public of the nation and the governmental authorities with a detailed spotlight to the public showing all the confirmed cases by incorporating blockchain with contact tracking apps. Also we further look into how open spaces might help with contact tracking by calculating the potential of COVID-19 contamination in the wider public and publishing this on a blockchain. These places could efficiently disclose possible transmission threats whilst still ensuring the data confidentiality and integrity. Finally, statistical solutions in diverse circumstances are displayed, and conclusions are formed.
