PastaCurveName enum

Native vs Non-Native representations

  • Both native and non-native field implementations are backed by BigInt.

  • Non-native types (e.g. PallasFp, PastaPoint) represent field elements as multiple fixed-size limbs (typically 6 BigInts) and use algorithms written in a constant-time style. However, because they rely on BigInt, these implementations are not guaranteed to be constant-time at the machine level and should not be considered fully side-channel resistant. They are, however, safer than native representations.

  • Native types (e.g. PallasNativeFp, PastaNativePoint) represent each field element as a single BigInt and use variable-time algorithms. These are not constant-time and are not intended to be safe against side-channel attacks.

Both representations share identical curve and algebraic semantics; the differences lie in representation, performance, and side-channel behavior.
