Correct me if I'm wrong: The entire point of Contact Tracing model is that the database of COVID19 positive cases is highly controlled to ensure quality data. I.E. if you test positive, your doctor gives you a one-time code to upload your information.<p>How / why is a block chain needed for this implementation? 90% of contact tracing is already decentralized and anonymized. If anything block chain will make it easier to finger print individuals by address.
