Any idea why I'm having this issue. My account initminer have all the keys which I can see when I'm using get\_account. However, all the keys have the same value. I'm not sure who creates these keys and when are these created. I suppose, these are created during the blockchain initiation. However, it's not mentioned clearly. Any inputs on this would be highly appreciated. Thanks in advance.
