Imagine this...

We live in an autonomous privacy/anonymity centered decentralized community, and everyone is required to get tested for the disease and share the results in a anonymous manner. Anonymous decentralized profiles of those with the disease light up in yellow to red, depending on the severity of their symptoms, while the profiles of those without the disease light up in "light green" to "bright green", depending on how healthy they are. Anyone can turn off the color when he/she feels uncomfortable... And everyone could be require to turn on his/her color at thesame time for research sake or for other good reasons. With this, the decentralized community/network lights up in different colors... until they all turn green (meaning everyone is cured and healthy)

Imagine what we can do with this^, and how beautiful and useful it will be for a decentralized community.

I bet most will be willing to get tested and share their data/results under the safety of such community. And lots of experiments and treatments will be tried on them by people with proven treatments/cure and experienced health workers.
