ScriptLanguage

class cometa.scripts.script_language.ScriptLanguage(value)[source]

Bases: IntEnum

Enumerates the types of scripting languages supported by Cardano.

Cardano supports different scripting languages for defining spending conditions and smart contracts. This enumeration categorizes the available script types into native scripts and Plutus scripts (V1, V2, V3).

NATIVE = 0

Native scripts use a simple expression language to define spending conditions.

They support basic operations like requiring specific signatures, time-locks, and boolean combinations (all, any, n-of-k). Native scripts are evaluated directly by the ledger without requiring a smart contract runtime.

PLUTUS_V1 = 1

Plutus V1 scripts introduced in the Alonzo hard fork.

Plutus V1 was the initial version of Plutus smart contracts, enabling complex spending logic through Haskell-based smart contracts compiled to Untyped Plutus Core (UPLC).

PLUTUS_V2 = 2

Plutus V2 scripts introduced in the Vasil hard fork.

V2 extended the ScriptContext to include: - Full redeemers structure - Reference inputs (CIP-31) - Inline datums (CIP-32) - Reference scripts (CIP-33)

PLUTUS_V3 = 3

Plutus V3 scripts introduced in the Conway hard fork.

V3 extended the ScriptContext to include governance features: - Map with all votes in the transaction - List of governance proposals - Optional treasury amount checking - Optional treasury donations
