Building a Private Genomics Study with Stoffel MPC Without Central Data Collection
I Built a Private Genomics Study with Stoffel MPC

I built a proof of concept using Stoffel MPC to conduct a private genomics study where 100 simulated participants computed aggregate allele counts without anyone ever seeing their complete DNA data. By leveraging multi-party computation, this approach allows Monadic DNA users to contribute directly to research while keeping their genetic information on their devices, eliminating the need for a central server to collect sensitive records.
We no longer have to rely on a more robust privacy policy or a more secure central database. We can simply avoid collecting the raw data in one place.

In genetics the end user is never the consumer. You have to collect blood, prepare it, sequence it. These are all highly specialised steps in which something will and can go wrong, and that’s why typically a hospital carries them out. That’s before even getting the device to do sequencing. The cheapest nanopore comes you at a couple ten thousand euros. Given the premise your work strikes me as oddly theoretical. Who is that mystery home DNA lab that needs decentralised private compute?
Also, and funnily enough, for much of the genomic pipelines to run (eg a paternity test or a cancer test), a home computer is sufficient. Again, of course, you would need proper medical training to read, interpret and judge the results, which is why a hospital does it… so what problem exactly are you solving?

Thank you vishakh82 for sharing.
It's great seeing folks apply PETs to key problems, no matter how theoretical they might seem now as evidenced by the comments. PoCs like this are steps in the right direction to make such work and ideas practical.

> Most genomic studies begin by asking participants to upload one of the most identifying and irrevocable pieces of data they own, their DNA.
I'm curious what the author means by "asking participants to upload ... their DNA", because I am not aware of any study that asked participants to do that.
