On-chain Among Us with provably fair roles and anonymous votes

A fully on-chain social deduction game - hidden roles as encrypted notes, night actions as private transfers, voting as anonymous channel transfers. No server can leak roles, no admin can peek, vote tallies are provably correct.

What this enables

→Provably fair social deduction. Every existing Mafia / Werewolf / Among Us game has the same trust problem: the server knows everything. Role assignment, night actions, vote counts - all opaque. STRK20 replaces the server with a smart contract that can't cheat, can't be bribed, and can't play favorites.
→Anonymous voting that changes the metagame. In every existing social deduction game, voting is public or semi-public - which produces degenerate strategies (retaliation, bandwagoning, anchoring by vocal players). Anonymous voting eliminates all of them. The game becomes purer: it shifts from "manipulate voting behavior" to "evaluate evidence."
→Staked competitive play. A new category: competitive social deduction with real stakes and cryptographic integrity. Buy in with shielded STRK20, play with provable fairness, win on skill, receive winnings privately. Doesn't exist anywhere today.
→A platform for the whole genre. Role assignment + private actions + anonymous voting generalizes - Secret Hitler, Avalon, Blood on the Clocktower, Coup, One Night Werewolf. The Phase 1 contract is a platform; each variant is a different configuration.

What you build

A game contract managing lobbies, role assignment (STARK-proven from committed seed), turn progression, and resolution. Roles are encrypted STRK20 notes - only the holder decrypts. Night actions (impostor "kills," seer "checks") are private transfers in player-to-game channels. Emergency voting is anonymous channel transfers - vote tally computed publicly, votes themselves unattributable. Session keys for scoped per-game permissions; paymaster so players never sign or pay gas during a round.

Why this is the killer app argument

Privacy tech needs applications that people actually want to use, not just power-user tools. Social deduction is:

→Massively popular - Among Us peaked at 500M MAU.
→Naturally multiplayer - 5–15 players per round, organic network effects.
→Session-based - 15 minutes, low commitment, high engagement.
→Improved by privacy, not just compatible with it - anonymous voting is a genuine gameplay improvement, not a feature bolted on.
