Functions

func CalcVoteSeq

func CalcVoteSeq(blockHeight uint64) uint64

CalcVoteSeq calculate the vote sequence seq 0 is the genesis block seq 1 is the the block height 1, to block height RoundVoteBlockNums seq 2 is the block height RoundVoteBlockNums + 1 to block height 2 * RoundVoteBlockNums consensus node of the current round is the final result of previous round

Types

type CoinbaseReward

type CoinbaseReward struct {
	Amount         uint64
