evalMultiSig ∷ (ShelleyEraScript era, NativeScript era ~ MultiSig era) ⇒ Set (KeyHash 'Witness) → NativeScript era → Bool Source #
Script evaluator for native multi-signature scheme. vhks is the set of
key hashes that signed the transaction to be validated.
validateMultiSig ∷ (ShelleyEraScript era, EraTx era, NativeScript era ~ MultiSig era) ⇒ Tx era → NativeScript era → Bool Source #
Script validator for native multi-signature scheme.
nativeMultiSigTag ∷ ByteString Source #
Magic number "memorialized" in the ValidateScript class under the method: scriptPrefixTag:: Core.Script era -> Bs.ByteString, for the Shelley Era.
eqMultiSigRaw ∷ MultiSig era → MultiSig era → Bool Source #
Check the equality of two underlying types, while ignoring their binary
representation, which Eq instance normally does. This is used for testing.
data MultiSigRaw era Source #
A simple language for expressing conditions under which it is valid to withdraw from a normal UTxO payment address or to use a stake address.
The use case is for expressing multi-signature payment addresses and multi-signature stake addresses. These can be combined arbitrarily using logical operations:
- multi-way "and";
- multi-way "or";
- multi-way "N of M".
This makes it easy to express multi-signature addresses, and provides an extension point to express other validity conditions, e.g., as needed for locking funds used with lightning.
