ScriptPubkey

class cometa.scripts.native_scripts.script_pubkey.ScriptPubkey(ptr)[source]

Bases: object

Represents a public key script (signature requirement).

This script evaluates to true if the transaction includes a valid key witness where the witness verification key hashes to the given hash. In other words, this checks that the transaction is signed by a particular key, identified by its verification key hash.

__init__(ptr)[source]

Return type:: None

__enter__()[source]

Return type:: ScriptPubkey

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

Return type:: None

__repr__()[source]

Return repr(self).

Return type:: str

classmethod new(key_hash)[source]

Creates a new public key script.

Parameters:: key_hash (bytes) – The 28-byte Blake2b hash of the verification key.
Returns:: A new ScriptPubkey instance.
Raises:: CardanoError – If creation fails.
Return type:: ScriptPubkey

classmethod from_cbor(reader)[source]

Deserializes a ScriptPubkey from CBOR data.

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

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

property key_hash: bytes

The verification key hash that must sign the transaction.

Returns:: The 28-byte Blake2b hash.

property hash: bytes

The hash of this native script.

Returns:: The 28-byte Blake2b hash.

__eq__(other)[source]

Checks equality with another ScriptPubkey.

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

__hash__ = None
