The way I understand is like this. These days people can do DNA test online and get in form of digital file. that file contains very sensitive data on you that you can use to know problems could have etc. So you need to keep that file in safe place that no can access to it without you permission. DNAtix offers that safe place that you need. It's on blochchain on for they are creating dapp that will allow to manage your DNA file easily and access to it any time, plus others services.
