PlutusV1Script

class cometa.scripts.plutus_scripts.plutus_v1_script.PlutusV1Script(ptr)[source]

Bases: object

Represents a Plutus V1 script.

Plutus scripts are pieces of code that implement pure functions with True or False outputs. These functions take several inputs such as Datum, Redeemer and the transaction context to decide whether an output can be spent or not.

V1 was the initial version of Plutus, introduced in the Alonzo hard fork.

__repr__()[source]

Return repr(self).

Return type:: str

classmethod new(script_bytes)[source]

Creates a new PlutusV1Script from raw bytes.

Parameters:: script_bytes (bytes) – The compiled Plutus script bytes.
Returns:: A new PlutusV1Script instance.

Raises:: CardanoError – If deserialization fails.
Return type:: PlutusV1Script

to_cbor(writer)[source]

Serializes the script to CBOR format.

Parameters:: writer (CborWriter) – A CborWriter to write the serialized data to.
