 #### 4.2.5 Combatting MEV
-As the consecutive period in which a single validator gains priority in block production extends, it may facilitate MEV extraction, potentially leading validators to include more transactions in the later blocks they consecutively produce. To constrain validators to promptly package transactions, within a validator's consecutive priority over n blocks, the transaction fees' split to the SystemRewardContract will increase linearly with block number, capped at the value denoted as antiMEVSystemRewardRatio.
-Respectively, the split ratio remains at initSystemRewardRatio when continuous block production is disabled. Once continuous block production is enabled (i.e., when n > 1), the systemRewardRatio is calculated as:

 ## 5. Incentive Fairness Analysis
 Within a single epoch, tail validators have fewer block-producing opportunities, but the allocation of priority rights is unbiased and cannot be manipulated. Therefore, from a statistical perspective, it is fair.
