Proof Of Fairness

Definition of Proof of Fairness

Proof of fairness refers to the ability to demonstrate that outcomes affecting value are produced and recorded according to predefined, verifiable rules. It does not assert that outcomes are favorable, random, or optimal, only that they are consistent with the declared process.

Separation of Outcome Generation and Recording

Fairness proofs rely on a clear separation between outcome generation and settlement recording. The system records outcomes as received from upstream sources and applies deterministic settlement logic without modifying the underlying result generation.

Deterministic Application of Rules

Fairness is evaluated based on whether the same rules are applied uniformly to all equivalent events. Deterministic application ensures that identical inputs produce identical ledger effects, independent of timing, network, or brand context.

Traceability of Outcome Effects

Each outcome that affects balances must be traceable from its origin through settlement and final state changes. Traceability requires stable identifiers, consistent mappings, and preservation of causal links across records.

Exclusion of Presentation-Based Evidence

Visual indicators, summaries, or isolated examples are not considered fairness evidence. Proof requires machine-verifiable records that represent complete histories rather than selective snapshots.

Handling of Adjustments and Exceptions

Fairness proofs must account for corrections and exceptions explicitly. Adjustments are recorded as new events referencing original records, preserving historical integrity while making changes auditable.

Reproducibility of Fairness Evaluation

An independent evaluator must be able to reproduce fairness checks using published rules and accessible records. If reproduction requires privileged access or undocumented logic, the fairness claim is unsupported.

Boundary of Fairness Claims

Proof of fairness is limited to the settlement and recording layer. It does not extend to randomness quality, game design, or external provider behavior unless those components are explicitly defined within system boundaries.

Non-Goals of Fairness Proof

Fairness proofs do not guarantee expected returns, absence of variance, or regulatory compliance. They establish only that recorded outcomes align with declared deterministic processes.
