For me, this is important because it can potentially rebalance value and its distribution through a system that can be verified through trustless mechanisms.
Some consensus mechanism are trusted ones. For such systems, to exclude malevolent actions is a trivial task. They are based on the "reputation" of known node participants (that are by definition not anonymous).
Now it would be an evolution to find a synthesis of those mechanism based on trust with a trustless protocol such as DPOS.
If that synthesis could be achieved, I would define such a mechanism as Reputational Enhanced Delegated Proof-of-Stake (REDPOS)
I know that @blocktrades has been throwing around ideas in his head for quite a while on building a web of trust. Eventually it will be solved effectively.
