Contract State Management Role

Go up to Terms and Definitions

The Contract State Management Role is responsible for establishing, updating, and reporting the FX contract state at the logical level.

This role includes consuming validated and semantically interpreted FX transaction information, determining applicable FX Contract State, applying allowed state transitions, publishing contract state information, and preserving transition provenance.

The Contract State Management Role participates primarily in the FX Logical Data Plane. It also supports the FX Logical Audit and Provenance Plane when state transitions preserve input references, rule context, producing Node, timestamp, and evidence expectations.

Specialization of Logical Node Role from Part 2: Distributed Node-Based Logical Architecture, Section 6.4, Logical Information Lineage from Part 2: Distributed Node-Based Logical Architecture, Section 8.10, and Traceability from Part 1: Conceptual Architecture, Section 7.10; generalised from contract lifecycle and state material in the original FX Demo Reference Architecture.

The Contract State Management Role does not prescribe a state-machine implementation, workflow engine, database table, event store, persistence mechanism, or orchestration tool.

The FX Contract State Node performs the Contract State Management Role by determining and publishing the FX Contract State for a validated transaction.
