Machine Identity

Plain-language definition

Machine identity must account for copying, forks, rollbacks, key rotation and substrate migration.

The definition is intentionally bounded. It identifies the property or role under discussion without converting terminology into a claim of deployment, recognition, personhood, citizenship, sovereignty, or authority.

Technical definition

Within the K01 knowledge model, Machine Identity is represented as a stable term object with code K01-TERM-010, canonical URL, claim status, topic owner, source links, related terms, last-reviewed date, research cutoff, and correction state. Relevant implementation components for the owning topic include stable subject identifiers; key rotation; compromise recovery; event chains; model and memory lineage; authorized succession; dispute records.

Legal or policy use

Legal identity is conferred and recognized through applicable institutions and law, not solely through cryptographic proof.

When a statute, regulation, standard, or external institution uses a different definition, that source-specific meaning controls the analysis of that source. The project definition is not silently substituted into current law.

What the term implies

The term implies that the stated property should be evaluated using the evidence appropriate to identifier continuity, cryptographic control, succession, forks, replicas and legal recognition. It supports precise reference, comparison, data exchange, and correction across public prose and machine records.

What the term does not imply

A machine identity record does not by itself create legal personhood, citizenship or authority.

It also does not convert a valid signature, credential, database record, model hash, or website into factual truth or legal authority without additional evidence and a competent decision.

Commonly confused terms

• Identity
• Persistent Identity
• Credential
• Workload Identity
• Signing Key
• Cryptographic Identity

Confusion is resolved by asking which property is actually at issue: technical control, continuity, evidence, authority, legal recognition, operation, or normative status.

Operational test

1. Name the subject and purpose.
2. Identify the source definition and jurisdiction or technical context.
3. Collect evidence for the specific property.
4. Record currentness and limitations.
5. Route any governance, registry, assurance, or capital decision to the proper authority.
