Architected a full-stack real-time gaming simulator featuring bidirectional WebSocket event broadcasting, ACID transaction isolation, and provably fair cryptographic randomness.
The Challenge: State Synchronization and Concurrency Under Load
Multiplayer wagering platforms must eliminate race conditions such as double-spending virtual credits while maintaining millisecond-level responsiveness for simultaneous users across game rooms.
WebSocket Room State Machine
Socket.io rooms handle real-time chat, bets, and multipliers. The Express backend enforces atomic database transactions in SQLite with immediate rollback on validation failure, preventing desynchronized client balances.
Key Engineering Challenges
- 1
Mitigating race conditions when hundreds of WebSocket actions arrive in the same tick.
- 2
Implementing seed-based provably fair RNG verification algorithms.
