Qualified Node

Return to Terms and Definitions

Discussion

A Qualified Node performs governed work after the architecture recognises its eligibility for a defined function. Qualification supports trust, cost attribution, provider comparison, compensation, and settlement in the Cost Recovery, Compensation, and Settlement Plane.

A Qualified Node satisfies the relevant interface, semantic, policy, evidence, security, residency, sovereignty, operational, and service-level criteria for a defined work type. Qualification prevents the architecture from treating an unverified or unsuitable Node as eligible for compensation.

A Qualified Node also supports competition among implementations. Different Nodes can compete to perform the same governed function when each Node satisfies the same qualification criteria and produces the required evidence.

Node recognised as eligible to perform a defined governed function

Note

A Qualified Node differs from a running Node. A running Node has operational presence. A Qualified Node has recognised eligibility for a defined governed function.

Qualification supports compensation eligibility but does not by itself prove that the Node completed a specific item of work.

Example

A sanctions screening Node satisfies the required policy, evidence, residency, security, and service-level criteria for sanctions screening in a defined jurisdiction. The architecture treats that Node as a Qualified Node for sanctions screening work.
