Functions

func AccumulateRewards

func AccumulateRewards(chainConfig *params.ChainConfig, header *types.Header, uncles []*types.Header) (minerBaseReward, uncleInclusionReward *big.Int, uncleCoinbase []common.Address, uncleReward []*big.Int, uncleHash []common.Hash)

AccumulateRewards credits the coinbase of the given block with the mining reward. The total reward consists of the static block reward and rewards for included uncles. The coinbase of each uncle block is also rewarded.
