Functions

func CalcVoteSeq

func CalcVoteSeq(blockHeight uint64) uint64

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 ConsensusNode

type ConsensusNode struct {
	XPub    chainkd.XPub
	VoteNum uint64
	Order   uint64
}

type UtxoViewpoint

type UtxoViewpoint struct {
	Entries map[bc.Hash]*storage.UtxoEntry
}

UtxoViewpoint represents a view into the set of unspent transaction outputs

func NewUtxoViewpoint

func NewUtxoViewpoint() *UtxoViewpoint

NewUtxoViewpoint returns a new empty unspent transaction output view.
