Hey guys, late to the conversation here, but here are my belated comments:
Does that sound like it's inline with the [financial wellbeing] hackathon's objectives?
Participants will create a decentralized product/service to help Alice and Bob participate in a viable and sustainable way in the emerging decentralized economy. which gives me an iffy feeling because it is reminiscent of the "free-lancing is a panacea for those with more money" spiel that Uber/AmazonFlex/etc sell people on but actually exploits the majority of their free-lancing contractors.
...With a blockchain twist, of course.
My knowledge of Biology is limited to what I learned in high school. [HackSeq]
I've worked in cancer research a little, but nothing computationally-related or relevant to the blockchain project proposed.
The infectious disease angle could be interesting if you could display a brief history of locations that sick-and-opted-in users have visited as like a tailwind on a map.
I think it could be even more interesting if expanded to gastrointestinal upset cases (early food poisoning detection system)
