Building Secure Raffle Systems: A Technical Guide
Design patterns behind compliant, auditable raffle platforms.
Raffle platforms must balance fairness, fraud prevention, and regulatory compliance. This guide outlines key technical components to build trustworthy systems that scale.
Core Architecture
- Immutable event logs and audit trails
- Entry validation (KYC, duplicate detection, device fingerprinting)
- Separation of concerns for entry, draw, and reporting services
Fair Draws
- Use cryptographically secure RNG; seed from verifiable sources
- Record draw parameters and results; publish verification artifacts
- Enable third-party oversight with read-only audit access
Payments & Channels
- Integrate mobile money and USSD with idempotent transaction handling
- Rate limit and anti-spam for SMS/web submissions
- Real-time dashboards and alerts for anomalies
RaffleHub implements these patterns with compliant workflows, audit-ready logs, and live draw tooling for transparency.
