No Debates — Case Study by Bankole David

the problem

Every group chat dies on the same three words: 'where should we eat?' Voting apps add friction with accounts and logins, so the decision still takes 40 messages of argument.

what i built

Built No Debates: type the options, spin a fair prize wheel with easing, tick sounds, and confetti, then share a sealed, tamper-proof verdict with one tap. Squad rooms let friends add options live for real-time group spins, and a speed round settles head-to-head duels.

• →Prize-wheel decider with easing, ticks, and confetti
• →Sealed receipts: hashed, timestamped, marked FAIR SELECTOR
• →Shareable verdicts: chat text, proof links, or PNG tickets
• →Squad spins: friends add options live, only the creator spins
• →Speed round duels with running tally and sprint champion
• →Embeddable live board, and a fair flip API for bots

tools, and why

React + Vite + Tailwind for a crisp, instant SPA. Canvas for the wheel with synthesized tick sounds via the Web Audio API. Convex for live squad rooms and anonymous usage counts. Vercel edge functions for sealed-receipt proofs and server-rendered OG share cards.

the hard part

Making a decision genuinely fair when the wheel runs on client devices. Solved by hashing every verdict into a sealed timestamped receipt whose proof breaks on any edit, and keeping verification and OG rendering on server-side edge functions.
