Predictions

Call it now. Show it later.

Write down your prediction: a result, a score, a winner, what happens next. Save it as a file or take a screenshot, and add it here. It is fingerprinted on your phone or computer, and never uploaded. You get a free receipt. Later, anyone can check the files existed, unchanged, by that day.

Your files never leave your phone or computer. We only receive the set's fingerprint, a code worked out from the files that can't be turned back into them.

Why record it

Anyone can say they saw it coming. A file that existed, unchanged, before it happened shows you wrote it down in time.

A receipt can't show you didn't stamp other predictions too. The link you shared at the time is what shows which one you stood by.

Tips

  • Write your prediction in a notes app and save it as a file, or take a screenshot of it, then add that file.
  • Share the link to this set's timestamp straight away: it shows the date, not your words. When it comes true, share the files.

What a receipt proves

A receipt proves that these exact files existed, unchanged, by the time shown on the receipt.

What it doesn't prove

  • It does not prove that what a file shows or says is true, or that a scene was not staged.
  • It does not prove who took the photos or made the files, or where.
  • It is not legal advice. Whoever settles a dispute, such as a deposit scheme, a court or a hire company, decides what evidence it accepts.
