Proposer Bonus

In BTTC, there is an additional element of committing periodic checkpoints to the TRON/BSC/Ethereum mainnet. This is a major part of the validator responsibilities and they are incentivized to perform this activity. This constitutes a cost to the validator which is unique to a Layer 2 solution such as BTTC. We strive to accommodate this cost in the validator staking reward payout mechanism as a bonus to be paid to the proposer, who is responsible for committing the checkpoint. Rewards minus the bonus is to be shared among all stakers; proposer and signers, proportionally.

To avail the bonus completely, the proposer must include all signatures in the checkpoint. Because the protocol desires ⅔ +1 weight of the total stake, the checkpoint is accepted even with 80% votes. However, in this case, the proposer gets only 80% of the calculated bonus.
