Every claim is guilty
until it's falsified.
AI mints claims faster than anyone can verify them. Falsify pays attackers to break yours — survive it, and it was never just faith.
The problem
AI now answers everything. Nothing verifies the answer.
You got an answer. Was it right?
Confident output, no proof. The cost lands on you.
Too much to hand-check
AI scale beats human review.
Another AI isn't the answer
AI checking AI is recursion.
Falsify puts a bounty on the claim. People are paid only when a deterministic test actually breaks it. Survival is proof — not another model's opinion.
One trustless loop
Trust is the bug. Falsify is the patch.
Put skin in the game
State your claim. Stake the bounty. Being wrong gets expensive.
Prove me wrong
Attackers hunt for the break. Bad guesses pay nothing.
Code decides
A deterministic check settles it. No human, no LLM, no appeals.

Who it's for
If you use AI output, or ship it, you need a way to know it's actually right.
Verify what you rely on
Put a bounty on it. A break now beats a failure later.
Catch hallucination cheaply
Pay attackers — only for real breaks.
Act on tested claims
A claim that survived a bounty beats one nobody attacked.
Why Falsify
Other approaches trust an opinion. Falsify trusts a broken test.
| Falsify | Another AI | Manual review | |
|---|---|---|---|
| How it verifies | a test breaks the claim | a model's opinion | a human's judgment |
| Trust anchor | deterministic rules | another unverified model | one person's view |
| Scales to AI volume | yes | yes | no |
| Incentive to find flaws | paid to break | none | salary |
Proven in the wild
Real breaks, settled by the deterministic verifier.
Math.add(a,b)
Claimed to sum. Gemini found a=1,b=1 → returns 0.
Vault.withdraw()
Claimed reentrancy-safe. The harness drained 11 ETH.
Your next claim
