The Proof Ledger

Every call, sealed when it is published. Check it yourself.

We say we never edit a call after the market answers. This page lets you prove it, in your own browser, without trusting us.

Verify the whole record

The button downloads the ledger and every published edition, then your browser recomputes each fingerprint with its own SHA-256. If a single character of any call had changed since it was sealed, the check would fail and name the call.

The chain head is submitted to the OpenTimestamps calendars after each session’s grading run, and the proofs appear here.
Check a call you saved

Nothing you paste leaves your browser. Only the fingerprint is compared.

How the seal works

Simple enough to rebuild in any language. The rules never change for a published entry.

01

Fingerprint the call

At publication, the call's exact words, test and deadline are written as canonical JSON (keys sorted, no spaces, UTF-8) and hashed with SHA-256.

02

Chain it to the last one

Each entry carries the fingerprint of the entry before it. Changing, removing or reordering any call breaks every fingerprint after it.

03

Anchor it to Bitcoin

The newest fingerprint goes to the public OpenTimestamps calendars, which write it into a Bitcoin block. Anyone can check the proof with the free OpenTimestamps tools.

The ledger began on 31 October 2026. Calls F-001 to F-018 were published before then and were sealed that day from the versions first committed to our repository. From then on, every call is sealed on the day it is published.

The ledger

Oldest first. The full file, with every byte that was hashed, is at /data/ledger.json.
