* `StartHeight` is set to the height that the candidate became an active validator (with non-zero voting power).
* `IndexOffset` is incremented each time the candidate was a bonded validator in a block (and may have signed a precommit or not).
* `JailedUntil` is set whenever the candidate is jailed due to downtime
* `SignedBlocksCounter` is a counter kept to avoid unnecessary array reads. `SignedBlocksBitArray.Sum() == SignedBlocksCounter` always.
* `MissedBlocksCounter` is a counter kept to avoid unnecessary array reads. `MissedBlocksBitArray.Sum() == MissedBlocksCounter` always.
