Reputation System

TAO Passport uses weighted reputation signals to calculate wallet trust.

Starter Signal Groups

Signal	Source	Purpose
Validator reliability	Chain	Measures validator consistency and operational trust.
Miner participation	Chain	Rewards durable subnet mining activity.
Governance activity	Chain	Identifies users participating in protocol decisions.
Subnet participation	Chain	Rewards sustained activity across Bittensor subnet roles and economies.
Community signal	Community	Captures durable non-code ecosystem contribution.

Scoring Principles

Scores must be explainable.
Weights must be documented.
Signals should prefer durable behavior over one-time actions.
Abuse risks should be reviewed before increasing a signal weight.

Provenance Metadata

Each reputation signal and timeline event should carry provenance metadata so a score can be audited instead of treated as a black box.

Provenance Fields

Field	Purpose
`sourceCategory`	Classifies whether the evidence came from chain, GitTensor, community, or a derived aggregate.
`sourceId`	Stable identifier for the underlying source record or aggregate.
`reference`	Human-readable reference used during debugging and support review.
`observedAt`	Timestamp for when the source evidence was last observed or refreshed.
`scoringModelVersion`	Reputation model version used when the score component was produced.
`confidence`	Maintainer confidence in the evidence quality (`high`, `medium`, `low`).
`evidenceLinks`	Optional links to methodology or source material relevant to the signal.

Interpretation

Chain and derived signals should usually have high confidence when sourced from fresh indexed data.
Community signals may have lower confidence because they often require softer heuristics or manual review.
observedAt should be shown with cache freshness metadata so stale evidence is visible.
scoringModelVersion should change whenever scoring weights or source interpretation changes.
