Can anybody explain the reward mechanism in Proof of Authority (PoA) protocol? What kind of reward is received by the validators in PoA?
So far I came up with the following points:
- There is no competition between miners, new blocks are created by the authorized nodes at any time.
- As there is no mining in PoA so there is no reward mechanism.
- The winning block contains only a header and address of the miner for reward.
But, I could not figure out what is the reward actually. Is this ether, transaction fee in gas or something else?
One incentive I could figure out is that individuals maintain their identity as a validator. Is there any other incentive for the validators?
