ScriptNOfK

class cometa.scripts.native_scripts.script_n_of_k.ScriptNOfK(ptr)[source]

Bases: object

Represents an N-of-K script that requires N sub-scripts to evaluate to true.

This script evaluates to true if at least N (required) of the sub-scripts evaluate to true. If N is greater than the number of sub-scripts, this script evaluates to false.

__init__(ptr)[source]

Return type:: None

__enter__()[source]

Return type:: ScriptNOfK

__exit__(exc_type, exc_val, exc_tb)[source]

Return type:: None

__repr__()[source]

Return repr(self).

Return type:: str

classmethod new(scripts, required)[source]

Creates a new ScriptNOfK with the given sub-scripts and required count.

Parameters:

scripts (NativeScriptList | List[Any]) – The list of native scripts. Can be a NativeScriptList or a Python list of native scripts.
required (int) – The number of sub-scripts that must evaluate to true.

Returns:

A new ScriptNOfK instance.

Raises:

CardanoError – If creation fails.

Return type:

ScriptNOfK

classmethod from_cbor(reader)[source]

Deserializes a ScriptNOfK from CBOR data.

Parameters:: reader (CborReader) – A CborReader positioned at the script data.
Returns:: A new ScriptNOfK deserialized from the CBOR data.
Raises:: CardanoError – If deserialization fails.
Return type:: ScriptNOfK

to_cbor(writer)[source]

Serializes the script to CBOR format.

Parameters:: writer (CborWriter) – A CborWriter to write the serialized data to.
Raises:: CardanoError – If serialization fails.
Return type:: None

to_cip116_json(writer)[source]

Serializes this object to CIP-116 compliant JSON.

Parameters:: writer (JsonWriter) – The JsonWriter to write the JSON to.
Raises:: CardanoError – If serialization fails.
Return type:: None

property required: int

The number of sub-scripts required to evaluate to true.

Returns:: The required count.

property scripts: NativeScriptList

The list of sub-scripts.

Returns:: The NativeScriptList containing all sub-scripts.

property hash: bytes

The hash of this native script.

Returns:: The 28-byte Blake2b hash.

__hash__ = None

__len__()[source]

Returns the number of sub-scripts.

Return type:: int

__eq__(other)[source]

Checks equality with another ScriptNOfK.

Parameters:: other (object)
Return type:: bool
