Functions ¶
func CalcVoteSeq ¶
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 BlockIndex ¶
BlockIndex is the struct for help chain trace block chain as tree
func (*BlockIndex) AddNode ¶
func (bi *BlockIndex) AddNode(node *BlockNode)
AddNode will add node to the index map
func (*BlockIndex) BestNode ¶
func (bi *BlockIndex) BestNode() *BlockNode
func (*BlockIndex) BlockExist ¶
func (bi *BlockIndex) BlockExist(hash *bc.Hash) bool
BlockExist check does the block existed in blockIndex
func (*BlockIndex) GetNode ¶
func (bi *BlockIndex) GetNode(hash *bc.Hash) *BlockNode
GetNode will search node from the index map
func (*BlockIndex) InMainchain ¶
func (bi *BlockIndex) InMainchain(hash bc.Hash) bool
TODO: THIS FUNCTION MIGHT BE DELETED
func (*BlockIndex) NodeByHeight ¶
func (bi *BlockIndex) NodeByHeight(height uint64) *BlockNode
NodeByHeight returns the block node at the specified height.
func (*BlockIndex) NodesByHeight ¶
func (bi *BlockIndex) NodesByHeight(height uint64) []*BlockNode
NodesByHeight return all block nodes at the specified height.
func (*BlockIndex) SetMainChain ¶
func (bi *BlockIndex) SetMainChain(node *BlockNode)
SetMainChain will set the the mainChain array
type BlockNode ¶
type BlockNode struct {
Parent *BlockNode // parent is the parent block for this node.
Hash bc.Hash // hash of the block.
Version uint64
Height uint64
Timestamp uint64
BlockWitness *common.BitMap
TransactionsMerkleRoot bc.Hash
TransactionStatusHash bc.Hash
}
BlockNode represents a block within the block chain and is primarily used to aid in selecting the best chain to be the main chain.
func NewBlockNode ¶
func NewBlockNode(bh *types.BlockHeader, parent *BlockNode) (*BlockNode, error)
func (*BlockNode) BlockHeader ¶
func (node *BlockNode) BlockHeader() *types.BlockHeader
blockHeader convert a node to the header struct
func (*BlockNode) CalcPastMedianTime ¶
type UtxoViewpoint ¶
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.
func (*UtxoViewpoint) ApplyBlock ¶
