Purpose of verification within the protocol
The Verification Model defines how Trust State Protocol distinguishes between events that may influence trust state and those that may not. Its role is to formalize the concept of verification without prescribing specific verification mechanisms, technologies, or authorities.
Verification in TSP does not establish truth in an absolute sense. It establishes that an outcome has been confirmed according to declared and deterministic criteria. The protocol treats verification as a prerequisite for trust state evolution, not as a guarantee of correctness.
By separating verification from trust update mechanics, TSP ensures that trust evolution remains grounded in observable resolution while remaining adaptable to diverse operational environments.
Verification as a prerequisite, not a judgment
Within Trust State Protocol, an event must be verified before it can influence trust state. Unverified outcomes are ignored by the protocol regardless of their apparent significance or severity. This requirement ensures that trust state is not influenced by allegations, intent, speculation, or incomplete information.
Verification does not imply endorsement, approval, or normative evaluation. It is a procedural condition indicating that an outcome has been confirmed according to the rules of the context in which it occurred.
Verification context
Every verified event is associated with a verification context. The verification context captures the conditions under which verification occurred and reflects the strength of confirmation. Verification context does not change the classification of an event, but it influences how strongly that event should affect trust state evolution.
Verification context may reflect factors such as mutual acknowledgment by participants, cryptographic confirmation, third party attestation, or system level guarantees. Trust State Protocol does not privilege any particular method. It requires only that the verification context be declared, deterministic, and reproducible.
Determinism and reproducibility
Verification decisions within TSP must be deterministic. Given the same inputs and conditions, an event must either be verified or not verified in the same way across implementations. Verification criteria may be complex, but they must not involve discretionary or subjective judgment at the protocol level.
This determinism is essential for interoperability and auditability. Trust state evolution relies on the assumption that verified events are recognized consistently across systems implementing the protocol.
Separation from evidence and dispute resolution
The Verification Model does not define how evidence is collected, evaluated, or stored. It also does not define how disputes are resolved. These processes occur outside the protocol and may involve human judgment, legal frameworks, or platform specific policies.
TSP records only the outcome of verification, not the underlying evidence or reasoning. If a dispute results in a revised outcome, that revision must be expressed as a new event rather than as a modification of a previously verified one.
Temporal anchoring of verification
Verification is temporally anchored at the point in time when confirmation occurs. An event influences trust state only from the moment it is verified, regardless of when the underlying interaction began or concluded.
This anchoring prevents retroactive trust manipulation and ensures consistency between verification timing and decay behavior. Delayed verification results in delayed trust updates.
Verification strength and uncertainty
Verification within TSP is explicitly imperfect. No verification context eliminates uncertainty. Even outcomes verified through strong mechanisms remain subject to decay and bounded influence.
Verification strength affects the weighting of events but does not bypass decay or create permanent trust. This design reflects the protocol’s assumption that all information becomes less reliable over time and that no single confirmation should dominate trust indefinitely.
Contextual scope of verification
Verification criteria are context specific. Different interaction domains may require different standards of confirmation. The protocol does not impose a uniform verification threshold across contexts.
However, verification contexts must be isolated in the same manner as trust states and events. Verification in one context has no bearing on trust evolution in another.
Independence from identity
The Verification Model does not require real world identity. Verification may occur between pseudonymous entities or through system defined identifiers. Identity disclosure, if used, is an implementation choice and remains external to the protocol.
This separation allows verification mechanisms to be adapted to privacy, regulatory, and operational constraints without altering trust mechanics.
Auditability without exposure
Verification within TSP is designed to be auditable without exposing sensitive information. Systems may demonstrate that verification criteria exist and are applied consistently without revealing identities, behavioral histories, or proprietary processes.
This property supports accountability while minimizing data retention and liability.
Relationship to trust state evolution
Verification does not directly modify trust state. It enables trust modification by allowing events to be admitted into the state transition process. The magnitude and direction of trust change are determined by state transition rules and decay, not by verification itself.
This separation preserves modularity and prevents verification mechanisms from becoming implicit policy levers.
