Sealed prediction series · Robinhood Chain 4663

The Hull Against the Machine

Each prediction states a question and a set of bands. We choose one, seal it, and anchor the seal in Bitcoin before the event. You pick before the timer ends. At zero, both answers open against the measured result.

This is not a Proof Posit. A Posit measures what happened. A prediction is a claim about what will. They share the seal apparatus and nothing else.

The live prediction

No predictions sealed yet.

The first prediction appears here the moment its seal is anchored. Nothing is published before the anchor confirms.

How this works

We seal our answer, and anchor it in Bitcoin, before the event.
You pick a band before the timer reaches zero.
At zero, both answers open against the measured result.
The seal proves we could not have changed ours afterwards.

Your pick is stored in your own browser. There is no account, no wallet, and nothing about you is sent anywhere. Clearing your site data clears your picks.

Every sealed prediction appears here on resolution. There is no mechanism to withdraw one.

The archive

Resolved predictions appear here, newest first. Every prediction keeps a permanent link and resolved predictions never move.

Verify a seal

The same six steps used on every Proof Posit. Any of them can be run without us.

  1. Compute the document digest: sha256 of the sealed bytes, and compare it with the seal record.
  2. Look up the ledger event by its exact id and read the record back.
  3. Verify both ATECC608B hardware signatures. Both chips sign, or nothing is written.
  4. Verify the OpenTimestamps proof against the Bitcoin block named on the card.
  5. Verify on chain if you prefer: chain 4663 verifies P-256 natively at 0x100 (RIP-7212), so a contract can check the seal with no oracle.
  6. Reproduce the resolution from the published working, against the resolution rule that was sealed with the prediction.

The permanent verification apparatus lives at jetfyul.com/verify/ and never moves.

Optional: be told when one resolves

This is entirely separate from your pick. Your pick stays in your browser either way and is never attached to this address. Used only to say that a prediction has resolved.
