How to set permissions within a blockchain

Question

From what I have read I've understood that in a private blockchain every participant can view all transactions. Now, if I have implemented a use case with private blockchain. Is there a way to set permissions so that only specified people can view data.

Answer 1

Yes there are blockchains that allows defining permissions. Hyperldeger is one such blockchain implementation that does it. It also gives an additional feature of vhannels which gives you the ability to configure the channels with data stored in the ledger of the participants in the specified channel only.

Answer 2

There are blockchains that allow defining permissions. Hyperledger Fabric is one of them. You have the ability to configure channels with data stored in the ledger of the participants in the channel only.
