# OES: The Omni Escrow System

OES is the execution kernel of the OmniPact protocol. It abandons the uncertainty brought by Turing-complete languages and instead adopts the architecture of Deterministic Finite State Machine (DFSM). This design principle ensures that the life cycle of each secured transaction is predictable, verifiable, and non-rollbackable.
