Scenario:
I have 3 organizations (O1-O3). O1 is an org of an applicant and O2/O3 administrate his public and private data shared with them. O1-O3 have private data shared with each other and O1-O2 have private data shared. The network is running, collections are already distributed and everything works fine.
When i now want to add more organizations (in terms of thousands, O4-O1000) of type applicant (O1) and each of them should have shared private data with Organization 2 (O2) and Organization 3 (O3), how do i approach this when the network is already live and running? Is it scalable? How would i add dynamically private data collections between those newly added organizations and the 2 established ones (O2 and O3)?
I already encountered this but it is not a solution to my problem.
