Check the record

Every event we record stays as it was recorded: the database refuses to change or delete one. Shortly after midnight in Tbilisi each finished day is sealed with a fingerprint of all its events, linked to the day before. Download any day and check it yourself.

How the seal works

  • The day's events are written out as one CSV file: every event, counted or not, oldest first — the minute, what happened, the page, the article, how the reader arrived, country, device, whether it counted and its receipt. No reader and no address is in it.
  • Its fingerprint is the SHA-256 of that file, exactly as you download it.
  • Its link is the SHA-256 of four lines: the previous day's link, the date, the number of events and the fingerprint. The first day follows sixty-four zeros.
  • Changing any sealed day changes its fingerprint, its link and every link after it. Keep a copy of the latest link, and no earlier day can be rewritten without you seeing it.

Check in your browser

Downloads each day shown, hashes it on your device and recomputes the links. Nothing is sent back.

Or in a terminal

The fingerprint of one day:

curl -s "https://www.outprint.ge/api/traffic/day?day=2026-09-18" | shasum -a 256

Its link, from the previous day's link, the date, the number of events and the fingerprint:

printf '%s\n%s\n%s\n%s' 1ceebfb031e3dafd5e6014f31be5ce0ecc1fc6e6dfbb4a1b2a42a91d0fae8539 2026-09-18 6 d1ee6a467b2f5125b0c5504dcc82ab4313a98f906dc495e422cf7c9c1ac2758f | shasum -a 256

Copies elsewhere

The fingerprints are not yet published outside Outprint. Until they are, a copy of the latest link is what protects the earlier days: save one now and check it again later.
