Can you explain some of the privacy mechanisms in Hyperledger Fabric v1.0 - those that are already implemented and that are planned to be implemented in the future?
I understand that channels are like separate blockchains. I also looked through the document https://jira.hyperledger.org/browse/FAB-1151 , where I found two more mechanisms: one is personal data, and the other is encryption. Can you explain what the beast will use for use in the following scenario.
Every car needs car insurance. Say a car owner wants to change his insurance company. He signs a contract with a new insurance company. Let's say there is a regulator. The new insurance company informs the regulator of the new contract. Then the regulator informs the old insurance company that the car is no longer insured, but does not inform them of the name of the new insurance company. Thus, we have assets that are shared on the network, but also some private data that only some participants can see. I assume this is one chain, so using multiple channels here does not make sense.
I do not fully understand the concept of private data. Is it supposed that the data should be private for only one partner / company or can be shared between several companies, but not all of them? Is this the case in the script? What would be the different reasons / options for using encryption and private data? What mechanism should be used in the described scenario?
