What would be the costs of a “two-round” Proof of Work algorithm compared to regular POW? More or less, for the same level of security? More or less, for the same incentives? What feature would make it more attractive for the mining cartel?
TRPoW does not affect the competition edge of a miner. So If everything stays the same, a miner will have a lower electricity bill
with more or less the same earning potential. So, it will reduce the miners business cost and increase their profit.
The mining cartel will make more money And with less running cost.
