LuckyBox Algorithmic Fairness & Cryptographic Randomness Whitepaper

1. Core Random Number Generation Architecture

LuckyBox rejects naive pseudo-random generators (such as traditional LCGs) and strictly adopts OS-level Cryptographically Secure Pseudo-Random Number Generators (CSPRNG), querying system entropy sources via Security Framework on iOS and /dev/urandom on Android (Random.secure() in Dart/Flutter).

This guarantees a statistically uniform distribution across all pool items, preventing any third-party from predicting or retroactively manipulating future lottery results.

2. Atomic Inventory Deduction & Zero-Delay Timing

To prevent concurrency anomalies or stage disputes, LuckyBox executes atomic inventory deduction and winner selection at the exact millisecond of trigger (t0). Front-end animations (wheel deceleration, slot rolling, scratch reveals) purely serve as physics-based visual representations.

3. 100% Offline Local Execution Security

All lottery computations occur 100% locally on the host device. Zero external cloud dependency guarantees zero latency and eliminates cloud backdoor vulnerabilities.

4. Enterprise Compliance & Verifiable Audit Reports

The Enterprise tier supports exporting complete draw histories with ISO timestamps in CSV format for corporate HR, legal, and compliance auditing.
