Validators vote power and centralized network structure, threatening network security. For more decentralized network, valitdator voting power and minimun validator fee ranges suggested in this paper.
When the validator voting power increased, the validator fee percenteces will be increased, delegators forced to find new validator (lower fee) for more profit.
Validators voting power not more than 1%, he can put minimum commision at 0%
Validators voting power from 1% till 5%, validator can put minimum commision at 5%
Validators voting power from 5% till 10%, validator can put minimum commision commision at 10%
Validators voting power more than 10%, validator can put minimum commision at 13%
This is suggestion, open for discussion, can be chanced later.
