Functions

func ExtractBlockTransactions

func ExtractBlockTransactions(msgBlock *wire.MsgBlock, txTree int8,
	chainParams *chaincfg.Params) ([]*Tx, [][]*Vout, []VinTxPropertyARRAY)

ExtractBlockTransactions extracts transaction information from a wire.MsgBlock and returns the processed information in slices of the dbtypes Tx, Vout, and VinTxPropertyARRAY.
