Consensus Mechanism: ETH uses Proof of Stake (PoS), while ETHPoW uses Proof of Work (PoW). Block Rewards: In ETHPoW, miners receive rewards for validating blocks through PoW, whereas in Ethereum (ETH), validators are rewarded through staking in PoS. Transaction Finality: ETHPoW may have longer transaction finality times compared to Ethereum, as PoW takes more time to reach consensus than PoS.
