As the title, we are talking about the popular consensus - as I know now that includes  POW, DPOW and POS. So what is the Best consensus in your opinion?
I my idea:
- POW: Consume much electric energy of our world => unnecessary wastage.
- DPOS: Does not consume much energy but quite centralized (There are some validators)
- POS: Does not consume much energy + More decentralized.

Have I understood right?
