Whenever someone makes a transaction it gets verified by the miners & after that it becomes the part of the ledger. So as a reward miners get a small amount of bitcoin. Now my doubt is the reward that a miner is getting for successful validation, it should also be added to ledger and needs to be verified by someone say 'new miner'. The new miner's reward should also be verified by someone else. And this process of verifying rewards will continue forever.
Is my understanding right or am I missing something?
