Share data between accounts on same node #78

Closed mrpuri closed 4 years ago

mrpuri commented 4 years ago

I have created four accounts, two on each node. I sent a message from one account say account1 on node 1 to account2 on node 2 and I also have an account - account3, present on node 2. Is there any method through which I can view the data shared to account2 from account3?

Accounts dont permission states at the vault level. So, by default, anything shared with node 2 will be viewable by all account holders on node 2. You can also query by account if you only want to return states for a particular account. See the API docs for VaultQueryCriteria.

Thanks a lot for clearing that Roger. Is there any way to implement privacy among accounts on the same node?

Sadly, there's no isolation at the node level but you can add application level controls to provide authorisation on a per account basis. This functionality would be baked into your CorDapp and the RPC client associated with it.
