Validator performance

The ValidatorPerformance entity provides a proxy metric to judge the validator's performance:

• On Casper 1.x, it is calculated as the percentage of rewards received per one token relative to the maximum ratio received by a validator in the given era. A validator that received the highest ratio will have a 100 score.

• On Casper 2.x, it is calculated as the percentage of cited block signatures produced by a validator compared to the total number of blocks produced in the given era. A validator whose signatures were cited for every block will have a 100 score. In the current Mainnet configuration, block signatures can be cited no later than 3 blocks after the block was produced.
