Verify the EHIQ prediction record
Every prediction is registered in an append-only, hash-chained ledger before its outcome is known. "Append-only" is only a promise about our database, so we anchor the chain externally: recompute the head and check the timestamp yourself. Nothing here asks you to trust us.

How to verify it yourself
- Download our signed registry export (published with the scoring code).
- Recompute each row's hash = sha256(canonical claim | previous hash); confirm the chain is unbroken and ends at the head above.
- Verify the OpenTimestamps proof for the head with ots verify — it timestamps the head on the Bitcoin blockchain, which we do not control.
- Cross-check the head against the signed commit in our public anchor repo.
The prediction track record is an interim, pre-registered, market-referenced record; skill numbers are shown only with sample size and a confidence interval, labeled not-decision-grade while the sample is small.
