pub fn new(consensus: &'a Consensus, store: &'a CS) -> Self

pub fn block_reward_to_finalize(
    &self,
    parent: &HeaderView
) -> Result<(Script, BlockReward), Error>

RewardCalculator is used to calculate block finalize target's reward according to the parent header. block reward consists of four parts: base block reward, tx fee, proposal reward, and secondary block reward.

pub fn block_reward_for_target(
    &self,
    target: &HeaderView
) -> Result<(Script, BlockReward), Error>

pub fn txs_fees(&self, target: &HeaderView) -> Result<Capacity, Error>

Miner get (tx_fee - 40% of tx fee) for tx commitment. Be careful of the rounding, tx_fee - 40% of tx fee is different from 60% of tx fee.

pub fn proposal_reward(
    &self,
    parent: &HeaderView,
    target: &HeaderView
) -> Result<Capacity, Error>

Earliest proposer get 40% of tx fee as reward when tx committed block H(19) target H(13) ProposalWindow(2, 5) target current / / 10 11 12 13 14 15 16 17 18 19 \ \ \ _///__/ \ \ _/// \ _// _______/
