Types

type Epoch 

type Epoch struct {
	Number      int64
	StartHeight int64

type PendingReward 

type PendingReward struct {
	Address  [20]byte `msgp:"address"`   // Validator's operator address in smartbch chain
	EpochNum int64    `msgp:"epoch_num"` // During which epoch were the rewards got?
	Amount   [32]byte `msgp:"amount"`    // amount of rewards
}

Because EpochCountBeforeRewardMature >= 1, some rewards will be pending for a while before mature

  1. retire itself with no pending reward
  2. inactive validator with no vote power and pending reward in prev epoch, which may escape slash if it votes nothing after double sign !!! maybe there should have more epoch not one.

	Pubkey       [32]byte `msgp:"pubkey"`    // Validator's pubkey for tendermint
	RewardTo     [20]byte `msgp:"reward_to"` // where validator's reward goes into
	VotingPower  int64    `msgp:"voting_power"`
	Introduction string   `msgp:"introduction"` // a short introduction
	StakedCoins  [32]byte `msgp:"staked_coins"`
	IsRetiring   bool     `msgp:"is_retiring"` // whether this validator is in a retiring process
}
