In this Substrate Recipe it says nothing about the rewards miners get for including blocks into the chain in the PoW consensus. But I found that Kulupu uses a rewards pallet which, at first glance, manages the rewards for the miners.
The questions are:

  • Is it necessary to implement a similar pallet to give miners rewards? Will the PoW chain reach consensus and function normally (produce blocks) without it? (as per recipe)
  • Are there any other (maybe Parity's) implementations of such reward mechanism?

Yes, you need to implement a pallet if you want to issue rewards, but it isn't required for PoW chain as such to operate.

The pallet Kulupu uses isn't very minimal, something simpler like what we used in Subspace can already be sufficient depending on the use case.
