Thonest — The public record for predictions

Called it? Prove it.

Lock your prediction before the outcome — the exact words, the original source, and the test that settles it — so nobody can rewrite the story later. Make the call here, or register one made anywhere else.

See what’s coming due · No account needed to read or verify anything.

The prediction doesn’t have to start here.

A call made on X, a podcast, YouTube, Substack, CNBC — or here — becomes the same locked record: the exact words, the original source, the date, and the test that settles it. You said it first? Now you can prove it.

Said on XPaste the post. We fetch it and confirm the account.

Said on a podcastPaste the episode or transcript. The quote is checked against it.

Said hereWrite it directly. The timestamp is the proof.

How it works

Put it on the record. Make your own prediction, or paste a public source where someone else made one.
Lock the test. Thonest works out what would settle it, by when, and from which source — and shows you that in plain English. You confirm before anything locks.
See what happens. Predictions settle the moment their locked condition becomes conclusive. Nobody moves the goalposts afterwards, including us.

Why this is worth more than a screenshot

A screenshot proves nothing — anyone can fake one, and the post behind it can be edited or deleted. Every record here carries four things instead, each checkable by someone who thinks we’re lying.

1 · The source’s own wordsWe don’t take the submitter’s word for the quote. The platform is asked directly, and the exact wording must appear in what it returns — or the record is refused.

2 · An independent snapshotThe page is saved to the Internet Archive at capture time, on a server we don’t control. When that fails, the record says so rather than implying corroboration it doesn’t have.

3 · Anchored to BaseA fingerprint of the record and its locked test is written to a public blockchain. Change one character afterwards and the fingerprint stops matching — publicly, permanently.

4 · A contract that can’t edit itselfBatches are chained on-chain and the registry has no edit or delete function. Not “we won’t” — we can’t, and neither can anyone who buys us.

What we deliberately don’t claim: none of this proves a statement is true. Provenance shows where it came from; anchoring shows it hasn’t changed. Anyone who tells you a blockchain makes something true is selling you something. The full argument, including what could still go wrong →
