Proof-of-fair-odds, called like a VAR.
An autonomous referee watches every World Cup line on the TxLINE feed and recomputes what the fair price should have been. Clean markets play on. Suspect moves get the yellow. Broken books see red — and every call is signed on Solana, where no one, including us, can overturn it quietly.
Match-day board
Every fixture the referee is watching right now. The bars put the quoted line up against the de-vigged fair line; the card in the corner is the verdict on the market, not the result.
Incident feed
The whistle moments from across the tournament — replayed from real tick history and the public scan archive, minute-stamped like a match report.
Referee report
After each review the decision sheet is hashed, signed by the referee's own wallet, and filed on Solana. The archived sheet and the on-chain digest have to agree — that agreement is the full-time whistle.
The rulebook
How to read the cards, and what each offence on the sheet actually means.
Integrity 85 and up. The book is priced sanely and the fair line sits where you'd expect. Nothing to review.
Integrity 60–84. Something's off — a slow quote, a margin drifting the wrong way. Logged and kept in view.
Integrity below 60. A serious offence: an arbitrage window or a stale line on a live match. Flagged loudly.
The last 1X2 tick is old while the match is live — the book is quoting a price the game has already moved past.
Implied probabilities sum below one. A riskless surface on the consensus line — the book is paying out more than it takes in.
The home probability jumped far beyond this fixture's own history — a sharp move worth a second look.
The margin fell hard in a single tick. The book's cushion is thinning fast, so the review flags it.
