Nobody can edit it.
A Tickerz print is sealed in Bitcoin once a day. A revision by the source is shown beside the first print, never over it. This page says how that works and what has gone wrong so far.
Every print is sealed, and anyone can check it
Each day at about 12:00 UTC, every index period written or revised since the seal before is hashed with SHA-256 and stamped with OpenTimestamps, which anchors the hash in a Bitcoin block. The proof for any day is public at /api/indices/proof?day=, and any OpenTimestamps client can verify it without trusting Tickerz. Every endpoint is documented in the API reference.
Terminal events are stamped the same way: the record at open, then each receipt at 24 hours, 7 days and 30 days, at /api/receipts/proof.
Rulebook v0.1, 2026-09-23
Every index page has a Resolution section: what it counts, the source, when it prints, the first print, the fallback when a source is late, the precision, what it costs to move the number, and a grade. Reference means a public record a venue can recount itself. Candidate means counted by Tickerz from a primary source, with a young rulebook. Display means a vendor's figure, shown and not for settlement. See only means a count of harm to people, never called.
A rulebook changes only by a new version with a date. A license names the version it settles on.
What went wrong
Stamping at open started late. The 68 Terminal events opened before 20:30 UTC on September 22 2026 were stamped after the fact, in hourly batches until 05:30 UTC on September 23, and each of their receipt cards says how late. Since 20:30 UTC on September 22 2026, every new event is stamped within about an hour of opening.
An early research claim that downside spikes recover rested on one date and was withdrawn on September 22 2026. The correction is dated on the research page.
The Activity score measures unusual attention, not merit. It is not a prediction of price: the median 7 day return after an event has been negative. The evidence page measures it live.
Where the numbers come from
Each index names its source and that source's terms on its own page. Primary sources are preferred: the Solana chain for $MINTS, the Department of Labor claims file for $LAYOFFS, the City of Chicago for $CRIME. Terminal prices come from CoinGecko and Alpaca. Every source is listed on the data page.
