===== Discussion =====

Node Identity uniquely distinguishes a [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Node]] within a defined architectural, logical, implementation, or deployment context. It provides the basis for attribution, authorization, monitoring, audit, provenance, replay, recovery, and evidence.

A Node Identity allows later parts to identify which Node produced information, consumed a Communication Endpoint, reported status, acknowledged a command, executed a Node Role, or generated evidence.

A Node Identity exists at the architectural level. A deployment profile may associate a Node Identity with a container name, pod name, process identifier, host name, network address, certificate, service account, or other runtime identifier. Those identifiers do not replace the Node Identity.


===== Definition =====

//identifier uniquely distinguishing a [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Node]] within a defined architectural context//

===== Source =====

Adapted from FX Demo Reference Architecture, Section 2.1.16, Node Identity; generalised from implementation-profile identity to conceptual architectural identity.

===== Note =====

A Node Identity is not a container name, pod name, host name, process identifier, user identity, organization identity, network address, or repository path.

===== Example =====

A Phase 0 implementation profile may assign a stable Node Identity to a health-monitoring [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Node]] so later reviewers can attribute its heartbeat records, status messages, audit entries, and evidence to the same architectural participant.
