I Built a Private Genomics Study with Stoffel MPC

    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?

    > 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.

      You're right, most analyses are done using biobanks, etc right now. The sentence is an oversimplification but people still implicitly contribute their data to insecure and centralized sources.

      If we can enable people to get sequenced not just when they are sick but for altruistic or financial reasons without leaking their DNA data, we could unlock much bigger datasets than currently available, especially from populations that are underrepresented or ignored.

    MPC for Multi-Party Computation, not for Model Predictive Control.

      Nowadays people would have guessed it was Model Context Protocol.
