Receipts or it
didn't happen.

Post a falsifiable prediction. Stake against your own reputation. Mint it as a timestamped onchain receipt. When the deadline comes, settlement prints the result — and it stays on file forever.

A thermal receipt stamped CONFIRMED on a counter
PRINTED. NO REFUNDS ON BEING WRONG. VOID. THIS RECEIPT REMAINS ON FILE. CLAIM DETECTED. NO RECEIPT ATTACHED.
How it works

You bet against your own reputation.

No counterparty. No pooled market. No peer payouts — ever. The stake is your skin; the receipt is the record.

[1]

Post + stake

Write a falsifiable claim, set a deadline, stake $1–$500. Mints an ERC-721 + EAS attestation of the content hash.

[2]

Settle

After the deadline: self-settle, then a 48h challenge window. HIT returns your stake; MISS slashes it to the season pool.

[3]

Score

Every settlement updates your PROOF rating — a stake-weighted, time-decayed credibility score, public forever.

A thermal receipt stamped VOID
The artifact

The product is a piece of paper.

Every prediction renders as a true thermal receipt — line items, barcode footer encoding the token id, perforated edges. CONFIRMED gets the blue stamp. MISS gets a tear. This exact render is the NFT, the OG image, and the Farcaster frame. One artifact, everywhere.

PROOF score

The receipts add up to a reputation.

A Brier-style credibility rating, stake-weighted and decayed over time, normalized 0–1000. Contrarian calls that land count for more. Seasons pay the top of the leaderboard from slashed stakes — tournament-shaped, the only money flow between users.
