Delegated proof-of-take (DPoS) is a fundamentally different consensus protocol from proof-of-ork (PoW). The difference between the two presents itself in the kind of freedom they promote; while DPoS is freedom under a benign master, PoW is freedom from domination.

What Is Freedom?

Freedom can be understood in negative or positive terms, thanks to Isaiah Berlin. Negative freedom, according to Berlin, is the absence of interference or constraints. Positive freedom, by contrast, is having the capacity to do something to realize one’s potential. Negative freedom is also known as liberal freedom. According to the classical political philosophers that Berlin followed (Hobbes, for instance), one can enjoy freedom only when free from interference. It does not matter if there is a master who can arbitrarily interfere. If there are multiple doors to choose from and gatekeepers at each door, liberals argue that freedom means choosing and going through a door without interference. Keep this analogy in mind.
