Reading from your whitepaper in the "Our vision" part it was stated that you intend to move from poor data security which is the current approach to the blockchain enabled data security which in turn is the core of the SSOT framework, what security measures are you looking at implementing?? because as far as i know especially in recent times there have been some reported case of "blockchain hack" I sincerely don't know how that's possible or how its been carried out even, but i will be glad if some more light is thrown in the area of Data security promised by the SSOT team.
Im interested in this as well, although most of the breaches that have been related to blockchain have been a result of poor exchange practices etc, very few are down to the blockchain itself (Looking at you Verge mining hack..) data security for medical records is going to be VERY important. I hope they plan on hiring a professional auditing and pen testing company like HackerOne to take care of this.
