Multiplayer Blackjack Platform Development

I need a full-featured, real-time multiplayer Blackjack platform where players seat themselves at virtual tables that match the betting limits they feel comfortable with—low, medium, or high stakes. There is no dealer or house edge; the system simply shuffles, deals, and manages each round while players compete against one another.

Core expectations
• Secure email-and-password account creation, with robust password reset and session management
• Provably fair, cryptographically secure card shuffling so any player (or auditor) can verify the outcome of every hand after it ends
• In-game balance tracking, chip movements, and automatic settlement of each pot
• Deposit and withdrawal flows through both traditional payment gateways and major crypto-wallets, with full transaction history available to the user
• Admin console that lets me freeze accounts, adjust balances, review logs, and set table parameters in real time
• Continuous fraud detection, collusion monitoring, and basic KYC hooks
• Scalable lobby system that spins up new tables as traffic grows, keeps idle tables invisible, and enforces the chosen stake ranges

Acceptance criteria
1. A user can register, fund an account, join any open table within their balance constraints, play hands seamlessly, and cash out—all in a single session.
2. After every shuffle, the system publishes a hash that, when the seed is revealed post-hand, allows anyone to verify randomness.
3. Admin actions (balance adjustments, bans, limit changes) are version-logged and cannot be altered retroactively.
4. End-to-end gameplay stress-tested for at least 200 concurrent players without disconnects or card-sync issues.

Feel free to recommend the best stack and multiplayer architecture (WebSockets, peer servers, cloud databases, etc.) as long as it meets these goals and leaves room for future table types.
