While staking, sometimes i get rewards which are not accepted, why is that ?
Let us say you stake and and the current block is #999. Then one of your unspent inputs stake and produce block #1000. Then someone else mines block #1001 and confirms the block you generated and your reward is safe..
Another scenario: Current block is #999. You stake and produce #1000, which is propogated into the network. But at the same time (roughly) a guy named Charlie stakes or mines block #1000 as well (this happens because your block #1000 is not propogated to his node yet). Now, depending on who creates block #1001, it can either build upon your block or the block mined by Charlie. And if block #1001 builds on Charlies block #1000, he gets his reward and your block gets orphaned leaving you with no reward.
This was written in a hurry, but I hope it helps.
Hi, I know this is an old post, but thanks for the explanation of how Orphans are created......
Partizanai, thanks for your reply, your are correct with that timing you mention there is plenty of time, thanks for the good news. BTW I have ventured away from eth already, but I guess now is the time to return with the last price I saw.....
