Stream confidentiality without duplicating items in stream

+4 votes

I read about How to selectively reveal data on a blockchain as mentioned in  

Lets say I have n nodes , I want to node1 to publish item which can be revealed to m nodes (not n-m nodes).

" For each participant who should see a piece of data, a stream entry is created which contains that data’s secret password, encrypted using that participant’s public key."

node1 needs to publish same secret password encrypted n times to stream.

Is my understanding correct?

I know you are working on MultiChain 2.0 which might have this feature

Yes, your understanding is correct. The item itself is only encrypted and published once. Each user who is meant to see the item is provided with the encryption password, in a way that only they can read.
