Public record · anchored on Bitcoin
Every result, on the record.
Each market-board event is written down the moment we detect it, before its effect is known. The result is added when the measuring window closes. Every paid report, registered change and claim check gets a receipt here too. Entries are chained together and timestamped on the Bitcoin blockchain once a day, so nothing can be edited, deleted or back-dated without it showing.
Check a receipt
Honesty score: checks on random dates.
Twice a day we also measure a few random sector-days when nothing happened. The dates are picked using the latest record hash as the random seed, so we can't choose flattering ones. A well-calibrated model should call about 1 in 10 of them a "clear effect". If that rate drifts far above 10%, we're crying wolf, and you'll see it here first.
Latest entries
Your browser recomputes each entry's fingerprint and checks it links to the one before it. Nothing to trust, just maths.

Bitcoin anchors
Once a day the latest record hash is written into a small text file, and that file is timestamped on Bitcoin with OpenTimestamps. Download both files and run ots verify anchor-DATE.txt.ots (after pip install opentimestamps-client) to prove the whole record up to that entry existed on that day. New stamps take a few hours to be confirmed in a Bitcoin block.

How the record works
- Each entry stores its details as exact text. Its body fingerprint is the sha256 of that text.
- Its record hash is the sha256 of
number|kind|time|previous hash|body fingerprint. Changing any old entry changes every hash after it. - Customer data is never published. Reports carry a data fingerprint: the sha256 of the exact data you uploaded, so you can later prove which data the result came from.
- The daily Bitcoin anchor fixes the whole chain in time. Not even we can rewrite it afterwards.
Cards that were already on the market board when the record started on 10 November 2026 are marked "recorded after the fact". Everything since then is recorded when it happens.
