Can anyone tell me the difference of Consensus Protocol

[Laland]

Can anyone help me understand what is the difference between POS and BFT. Are they the same thing?
and why some public-chain claims that they do not mine ?
Also, some articles say that pBFT is not available for public chain. How about dBFT?

Anyway, I was confused by the consensus protocols and can't understand why some so-called public chain does not mine.

Links below will provide you some useful information about the Consensus Protocol:

and why some public-chain claims that they do not mine ?

POS offers a linear scale regarding the percentage of blocks a miner could confirm since it’s based on that person’s stake in the cryptocurrency. That means someone with ten times more coins (e.g. - $10,000 vs. $1,000) would only mine ten times more blocks.

Also, some articles say that pBFT is not available for public chain. How about dBFT?

On a dBFT blockchain, the consensus has to be achieved among the specialized bookkeeping nodes only as most Bitcoin users do not operate miners.

Thanks a lot! I understnad now

Here is a link to a small repost that explains many of the consensus algorithms if you need any additional information.
