PlutusV2Script

class cometa.scripts.plutus_scripts.plutus_v2_script.PlutusV2Script(ptr)[source]

Bases: object

Represents a Plutus V2 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.

V2 was introduced in the Vasil hard fork. The main changes were to the ScriptContext which was extended to include: - The full “redeemers” structure - Reference inputs (CIP-31) - Inline datums (CIP-32) - Reference scripts (CIP-33)
