## Описание столбцов в тултипе

- bro score. The score of the validator by bro score.
- voting power. The score of validator according by voting power
- moniker (link to mintscan. to cyb.ai in bostrom). The moniker of the validator.
- costs optimization. The cost optimization criteria of the validator. It depends on the validator's commission ($greed%) and decreases when the commission increases. It's equal to zero if the commission of the validator is zero to avoid the advertising effect. 
- decentralization. This criterion helps decentralize the network. The decentralization level depends on the validator's voting power rank ($validator_rank). It logarithmically increases with increasing rank number. 
- confidence. The confidence of the validator depends on the share of tokens ($ownership) which validator delegates to itself. It increases from 0 to 20% rapidly and then decreases back to zero, to avoid super-newby validators and CEXes.
- participation. This criterion is about the number of votes ($votes) for the last 5 ended proposals.
- reliability. We can define reliability without any precommits calculations. To understand the reliability we can divide staked tokens (\$staked) into delegator shares (\$delegator_shares). The result should be equal to 1 if everything is ok and there is no token loss by slashing. Otherwise, the criterion points decrease with the result decrease. 
- total. The sum of the criteria points
