The Zero Cup · 0G's Global Vibe Coding Tournament

Competition Rules

The main page gives you the essentials — this is the full playbook: every cut, every deadline, every dollar. Read it once, then go build.

Format & schedule

01Six rounds, one champion. An open group stage, then pure knockout: the field cuts to 32, 16, 8, 4, 2, and one. The brief: build AI-native apps, agents, companions, or games using 0G — decentralized AI storage, compute, and chain.
02Every deadline is a cut. The full calendar, registration to crown. One date matters above all: JUL 8 is the last submission deadline anywhere in the bracket — after that lock, no more changes.
03Deadlines lock a snapshot. You submit a public repo URL plus a description, and at each round's deadline we freeze a snapshot. That exact version is what gets judged — push after a lock all you want, it counts next round, until the final lock on JUL 8.
04One project, one team. Each team fields one project, and each builder rides with exactly one team — the platform enforces both. Lock in your squad early; mid-bracket roster churn is how teams lose.

Judging & voting

05Judges run the early rounds. From the group stage through the Round of 16, judges score every locked snapshot against the round's rubric. Scores are normalized across judges — a harsh judge can't sink you, a generous one can't carry you.
06Community takes the quarters. From the quarter finals on, public voting decides who advances — quarters JUL 8–10, semis JUL 12–14, the final JUL 16–18. Votes outside a window don't count. Ship something people want to vote for.
07No judging your own team. A judge never scores a project from a team they belong to. Conflict-of-interest is enforced by the platform, not the honor system.

Advancing

08Improve and resubmit, that's the meta. Between the judged rounds your project is open for upgrades, and the next snapshot is the one that counts — until the final lock on JUL 8, when one build rides through the quarters, semis, and final. The teams that go deep aren't the ones that started best — they're the ones that shipped the most between cuts.
09Top scores move on. Each round, the highest-ranked projects fill the next bracket; everyone else is out. Whatever you've submitted when the round locks is what gets judged — nothing submitted for the round, nothing to judge, you're done.
10Ties break in order. Dead heats resolve in a fixed chain: judges' first-choice picks, then earliest locked submission, then an organizer ruling. Every tiebreak is logged.

Prizes

11Prizes stack as you climb. $17,000 total, and every tier adds to the last. Crack the Top 8 and $500 per project is locked in, guaranteed.
12The exact ladder. Top 4 adds $1,000, Top 2 adds $2,000, and the champion adds the $5,000 grand prize on top of everything else.
13Champion takes $8,500. $500 + $1,000 + $2,000 + $5,000 — the full stack. Runner-up walks with $3,500, and even a quarter-final exit pays.

Fair play

14Vibe coding is the game. Building with AI tools and prompts isn't cheating — it's the whole point of the tournament. Use every model, agent, and copilot you can get your hands on; just own the result and know how it works.
15How you get cut. Submitting someone else's work as your own, rigging the community vote — bots, bought votes, sock puppets — misrepresenting what your app actually does, or taking your repo private mid-tournament. Any one of them is a disqualification, no rematch.
16Appeals exist, organizers decide. Think a call went wrong? Your team can file an appeal through the platform and organizers review it on the record — but their decisions on scores, advancement, and the cup are final.

Wondering whether your project can enter at all? That's the project submission criteria.
