ZERO CUP · PROVABLY FAIR AI GAMING
IT CAN'T SEE YOU. IT READS YOU.
Provably fair gaming, for AI opponents, not just RNG.
The first game built fully on 0G. Outdraw a blind AI, then prove it never cheated.

THE PROBLEM
AI GAMES FEEL RIGGED.
You fight a black box. When you lose, you wonder if the server cheated, and you can never prove it.
DID IT READ ME?
Or did the server peek at my input before locking its move?
"PROVABLY FAIR" = RNG
Dice and slots get verified. Nobody verifies an AI decision made on hidden info.
NO PROOF, NO TRUST
"The AI doesn't cheat" is only marketing until you can check it yourself.
THE SOLUTION
A DUEL THE AI CAN'T RIG.
A dark western pixel duel against ZEGON , a blindfolded AI gunslinger. The blindfold is real: a sealed 0G TEE.
01
It reads your past patterns, sealed on 0G Compute.
02
It commits its move on-chain before your buttons unlock.
03
You act blind, then VERIFY the round was fair.

HOW A ROUND WORKS
COMMIT BEFORE YOU MOVE.
01
ZEGON LOCKS IN
Move hash posted on 0G Chain. Timestamp frozen.
→
02
YOU CHOOSE
Shoot, dodge or use an item, blind. Your pick was never in the model input.
→
03
REVEAL
Both moves open. Hash matches. The round resolves.
NO RETROACTIVE CHANGES
ZEGON can't wait for your input and swap its move. The chain timestamp proves it committed first.
0G IS NOT A BOLT-ON
TAKE 0G OUT AND THE GAME BREAKS.
WITHOUT 0G
"It read you" is just text on a screen
Commit reveal is a server you must trust
The duel log is a database we control
Ranking is JSON on a server
WITH 0G, ZEGON
Sealed inference plus verifiable attestation
Smart contract ZegonDuel.sol on Galileo
0G Storage blob for re-verification

HONEST CLAIM » ZEGON predicts using only your history, sealed in a TEE, and commits its move on-chain before you move. It cannot have seen your shot or changed its answer afterward.
THE FULL 0G STACK
ALL THREE PILLARS, EVERY ROUND.
01
0G COMPUTE
SEALED INFERENCE
Runs ZEGON's brain inside a TEE and proves the inference used your history only, never your live pick.

02
0G CHAIN
PROVABLY FAIR
Stores the commit before you act, plus the daily pool and global ranking. Proof ZEGON could not change its move.

AFTER THE DUEL
DON'T TRUST US. CHECK THE PROOF.
VERIFY opens the explorer and shows ZEGON's commit timestamp sits before the moment you chose, and that the sealed model only ever saw your history.

HOW WE BUILT IT
VIBE CODED, THEN TESTED HARD.
Greenfield inside the tournament window. Two builders plus Claude Code and Cursor agents, iterating: prompt, playtest, feedback, resubmit.
»
Combat simplified after playtest: 1-click items, hearts for lives, 2/2 streak.
»
Result panel and score breakdown redesigned in one session from visual feedback.
»
The player never pays gas. A server wallet sponsors it, so onboarding is one click.

WHY NOW
THE MOMENT IS RIGHT.
01
TRUST IN AI IS BROKEN
AI opponents are everywhere, and players trust them less than ever. Proof is the missing piece.
02
0G MAKES IT AFFORDABLE
Sealed inference plus an on-chain commit, every single round, is now cheap enough to ship in a real game.
03
AGENTIC PLAY NEEDS TRUST
As AI agents start to play and wager, they need programmable trust primitives. Provably fair is that primitive.
04
GAMES DRIVE ADOPTION
Games are the fastest path to mainstream crypto. Players feel the value in seconds, no whitepaper required.

THE ASK
HELP A SMALL GAME WIN .
We are a small team going up against products that are not games. A Zero Cup win is not a trophy for us, it is fuel: it lets us keep building, prove that games belong on 0G, and bring the next wave of players in.
