Code : github

An on-chain take on the classic Mafia party game. Players stake SOL to join a lobby, get assigned a hidden role (Mafia / Citizen / Doctor) via verifiable randomness, and play through night and day phases. The cryptographic twist: roles are sealed in a vault — the server itself can’t see who is Mafia.

How it works

• Stake SOL to join a lobby
• Roles are dealt through verifiable randomness and kept private from the server
• Night phase → private votes & eliminations; Day phase → discussion & voting
• The SOL pot is paid out automatically on-chain to the winning faction
