Types

type BlockIndex 

type BlockIndex struct {
	Header block.BlockHeader

	// pointer to the index of the predecessor of this block
	Prev *BlockIndex

	// pointer to the index of some further predecessor of this block
	Skip *BlockIndex

	// height of the entry in the chain. The genesis block has height 0；
	Height int32
	// Which # file this block is stored in (blk?????.dat)
	File int32
	// Byte offset within blk?????.dat where this block's data is stored
	DataPos uint32
	// Byte offset within rev?????.dat where this block's undo data is stored
	UndoPos uint32
	// (memory only) Total amount of work (expected number of hashes) in the
	// chain up to and including this block
	ChainWork big.Int
	// Number of transactions in this block.
	// Note: in a potential headers-first mode, this number cannot be relied
	// upon
	TxCount int32
	// (memory only) Number of transactions in the chain up to and including
	// this block.
	// This value will be non-zero only if and only if transactions for this
	// block and all its parents are available. Change to 64-bit type when
	// necessary; won't happen before 2030
	ChainTxCount int32
	//status of this block. See enum
	Status uint32
	// (memory only) Sequential id assigned to distinguish order in which
	// blocks are received.
	SequenceID uint64
	// (memory only) Maximum time in the chain upto and including this block.
	TimeMax uint32
	// contains filtered or unexported fields
