They really don't have any similarities, so I'm not sure that there's much point in comparing them or talking about their differences. If you understand what PoW is and what it does and you understand BFT algorithms and what they do, there's no much else to know. Both algorithms are algorithms designed to get eventual agreement on how to make forward ...

PoW and BFT solve different problems. A couple of differences: BFT assumes the nodes (aka miners) are known in advance. PoW / Nakamoto Consensus allows anyone to become a node (miner). BFT assumes nodes do not change over time. PoW / Nakamoto Consensus does not make this assumption. BFT does not allow forks. PoW/NC allows temporary forks under normal ...
