Remote cohort storage/blockchain function

Note to those subject to European Union General Data Protection Regulation (GDPR). GDPR becomes enforceable from 25 May 2018. The storage of strongly encrypted personal data by us in a way that we cannot possibly decrypt it and confirmed by blockchain should qualify as "data protection by design". If you have any reservations about our approach, please do not use this software - use SDQcohort instead.
Note to users of this remote cohort storage/blockchain function.
If you forget your cohort name, we have no way whatsoever of advising you of it. It is not possible to decrypt or identify your cohort without the EXACT cohort name and UserID (including capitalisation)!
