blockFilterHeader

Arguments

:: BlockFilterHeader

previous header

-> BlockFilter

current filter

-> BlockFilterHeader

Calculate the header for the block filter

filterHeaderToHex :: BlockFilterHeader -> Text

filterHeaderFromHex :: Text -> Either String BlockFilterHeader

genesisHeader :: BlockFilterHeader

filterContents

Arguments

:: [ByteString]

previous output scripts spent in this block

-> Block

-> [ByteString]

Calculate the list of scripts which belong in the BIP158 block filter

encodeFilter

Arguments

:: [ByteString]

output scripts spent in this block

-> Block

-> BlockFilter

Construct a BIP158 filter from a block

isMember

Arguments
