Functions

func CheckMerkleBlock

func CheckMerkleBlock(m msg.MerkleBlock) ([]*common.Uint256, error)

take in a merkle block, parse through it, and return txids indicated If there's any problem return an error. Checks self-consistency only. doing it with a stack instead of recursion. Because... OK I don't know why I'm just not in to recursion OK?

func NewMerkleBlock

func NewMerkleBlock(txs []*types.Transaction, filter *Filter) (*msg.MerkleBlock, []uint32)

NewMerkleBlock returns a new *MerkleBlock

type TxFilter

type TxFilter interface {
	// Load loads the transaction filter.
	Load(filter []byte) error

	// Add adds new data into filter.
	Add(data []byte) error

	// MatchConfirmed returns if a confirmed (packed into a block) transaction
	// matches the filter.
	MatchConfirmed(tx *types.Transaction) bool

	// MatchUnconfirmed returns if a unconfirmed (not packed into a block yet)
	// transaction matches the filter.
	MatchUnconfirmed(tx *types.Transaction) bool
}

TxFilter indicates the methods a transaction filter should implement.
