Functions

func BlockConsumesOutpointWithAddresses

func BlockConsumesOutpointWithAddresses(block *dcrutil.Block, addrs map[string]TxAction,
	c *dcrrpcclient.Client, params *chaincfg.Params) map[string][]*dcrutil.Tx

func BlockReceivesToAddresses

func BlockReceivesToAddresses(block *dcrutil.Block, addrs map[string]TxAction,
	params *chaincfg.Params) map[string][]*dcrutil.Tx

BlockReceivesToAddresses checks a block for transactions paying to the specified addresses, and creates a map of addresses to a slice of dcrutil.Tx involving the address.

func BuildStakeTree

func BuildStakeTree(blocks map[int64]*dcrutil.Block, netParams *chaincfg.Params,
	nodeClient *dcrrpcclient.Client, poolRequiredHeight int64, DBName ...string) (database.DB, []int64, error)

func FeeInfoBlock

func GetDifficultyRatio

func GetDifficultyRatio(bits uint32, params *chaincfg.Params) float64

GetDifficultyRatio returns the proof-of-work difficulty as a multiple of the minimum difficulty using the passed bits field from the header of a block.

func HashInSlice

func HashInSlice(h chainhash.Hash, list []chainhash.Hash) bool

HashInSlice determines if a hash exists in a slice of hashes.

func IncludesStakeTx

func IncludesStakeTx(txHash *chainhash.Hash, block *dcrutil.Block) (int, int8)

IncludesStakeTx checks if a block contains a stake transaction hash

RevokedTicketsInBlock finds all the revoked tickets in the block.

func TicketsInBlock

func TicketsInBlock(bl *dcrutil.Block) []chainhash.Hash

TicketsInBlock finds all the new tickets in the block.

func TicketsSpentInBlock

func TicketsSpentInBlock(bl *dcrutil.Block) []chainhash.Hash

TicketsSpentInBlock finds all the tickets spent in the block.

func TxhashInSlice

func TxhashInSlice(txs []*dcrutil.Tx, txHash *chainhash.Hash) *dcrutil.Tx

func VotesInBlock

func VotesInBlock(bl *dcrutil.Block) []chainhash.Hash

VotesInBlock finds all the votes in the block.

Types

type BlockWatchedTx

type BlockWatchedTx struct {
	BlockHeight   int64
	TxsForAddress map[string][]*dcrutil.Tx
}

BlockWatchedTx contains, for a certain block, the transactions for certain watched addresses

type TxAction

type TxAction int32

TxAction is what is happening to the transaction (mined or inserted into mempool).

const (
	TxMined TxAction = 1 << iota
	TxInserted
)
