Has the fundamental problem in cryptovoting, one person, one vote, been solved?

Please do not answer with "it cannot be done" answers; they are useless.

Has the fundamental problem in cryptovoting, one person, one vote, in a completely decentralized or blockchain centric manner been solved?

In other words, how can votes be allocated in a decentralized manner?

The intent of this question presupposes that vote allocation is not delivered by a state, that a blockchain itself can at the very least implement a completely basic, pure democracy: truly one person, one vote.

How can this intent be implemented?
