Documentation

data InputScript

Standard input scripts (also known as "scriptSig")

Constructors

CoinGeneration !RawScript

coin generation (the script has no meaning)

RedeemAddress !SignatureExt !PubKey

redeem a standard (to-address) transaction: <sig> <pubKey>

RedeemPubKey !SignatureExt

redeem a to-pubkey transaction (?)

RedeemMultiSig [SignatureExt]

redeem a multisig transaction

RedeemP2SH [SignatureExt] !RawScript

redeem a pay-to-script-hash transaction (???)

RedeemEmpty

OP_TRUE - accepts an AnyCanSpend script

UnknownInput (Either RawScript Script)

something else (that is, non-standard)

Instances

Eq InputScript

Methods

(==) :: InputScript -> InputScript -> Bool

(/=) :: InputScript -> InputScript -> Bool

Show InputScript

Methods

showsPrec :: Int -> InputScript -> ShowS

show :: InputScript -> String

showList :: [InputScript] -> ShowS

isStandardInputScript :: InputScript -> Bool

data OutputScript

Standard output scripts (also known as "scriptSig")

Constructors

PayToAddress !PubKeyHash

OP_DUP OP_HASH160 <pubKeyHash> OP_EQUALVERIFY OP_CHECKSIG

PayToPubKey !PubKey

<pubKey> OP_CHECKSIG (accept generation, for example, but also others?)

PayToMultiSig !Int [PubKey]

eg. OP_2 <pubkey1> <pubkey2> <pubkey3> OP_3 OP_CHECKMULTISIG

PayToScriptHash !ScriptHash

OP_HASH160 <script-hash> OP_EQUAL

Unspendable

OP_RETURN {zero or more ops}

AnyCanSpend

(empty)

UnknownOutput (Either RawScript Script)

something else (that is, non-standard)

Instances

Eq OutputScript

Methods

(==) :: OutputScript -> OutputScript -> Bool

(/=) :: OutputScript -> OutputScript -> Bool

Show OutputScript

Methods

showsPrec :: Int -> OutputScript -> ShowS

show :: OutputScript -> String

showList :: [OutputScript] -> ShowS

isStandardOutputScript :: OutputScript -> Bool

createInputScript :: InputScript -> RawScript

Note: RedeemP2SH is a hack. I should think again how that should work (certainly not this way...)

createTxInput :: TxInput InputScript -> TxInput RawScript

createOutputScript :: OutputScript -> RawScript

createTxOutput :: TxOutput OutputScript -> TxOutput RawScript

recognizeTxInput :: TxInput RawScript -> TxInput InputScript

Recognize standard input scripts (also known as "scriptSig").

We need the whole TxInput since coinbase transactions are not possible to recognize only from the script (which can be anything).

recognizeInputScript :: RawScript -> InputScript

Note: this cannot recognize coinbase transactions.

recognizeTxOutput :: TxOutput RawScript -> TxOutput OutputScript

Recognize standard output scripts (also known as "scriptPubKey")

recognizeOutputScript :: RawScript -> OutputScript

recogPayToMultiSig :: [Opcode] -> Maybe (Int, [PubKey])

recognizeTx :: Tx RawScript RawScript -> Tx InputScript OutputScript

recognizeBlockTxs :: Block (Tx RawScript RawScript) -> Block (Tx InputScript OutputScript)
