====== 5.4 FX Demo Logical Node Network ======
[[fxdemo:03-part:05-fx-demo-logical-profile-overview:start | Go To FX Demo Logical Profile Overview ]]

The FX Demo Logical Node Network consists of identifiable FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Nodes]] that perform FX-specific responsibilities and communicate through explicit FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Communication Endpoints]].

The network includes FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Nodes]] for transaction intake, validation, semantic interpretation, contract state management, cash-flow computation, policy and release, audit and provenance, health and observability, registry and coordination, replay and reconstruction, and external oversight consumption.

Each FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Node]] has a logical responsibility within the FX Demo. The logical architecture treats those responsibilities separately, even when a later implementation profile packages several responsibilities into a single runtime artifact or distributes a single responsibility across multiple runtime artifacts.

The FX Demo Logical Node Network supports modularity, reviewability, controlled evolution, operational coordination, [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]], provenance, release control, replay, reconstruction, and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] planning.
