Proof of authority reward mechanism

Question

1. 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?

2. One incentive I could figure out is that individuals maintain their identity as a validator. Is there any other incentive for the validators?

Answer 1

The sealer does receive the transaction fee
