Script

class blsct.Script(obj: Any = None)

Represents a script, which may be a scriptPubKey, scriptSig, or scriptWitness. Also known as CScript on the C++ side.

A Script appears as an attribute of CTxOut (scriptPubKey) or CTxIn (scriptSig and scriptWitness), and is not meant to be instantiated directly.
