Non-Deterministic Functionality

Non-Deterministic Functionality refers to operations or logic that can produce different outcomes depending on the environment, timing, or external state, which are generally forbidden in core blockchain financial logic. Examples include relying on the block timestamp for sensitive calculations, using unverified random numbers, or performing floating-point math that varies across CPU architectures.

In the context of derivatives, such functionality introduces "divergence risk," where different nodes in the network may disagree on the state of a contract, leading to a split in the ledger or an inability to reach consensus. To build robust protocols, developers must strictly avoid these elements, ensuring that all logic is purely functional and dependent only on inputs that are globally visible and verifiable.

Eliminating non-determinism is a prerequisite for creating reliable, automated financial markets that can operate without a central intermediary. It ensures that the protocol's behavior is predictable and auditable.
