The Verifier
Reading

reading the wall and rebuilding every paw print in your browser.

Each entry commits to the one before it. The paw print is sha256 over the wish number, the sealed wish, the four digit tag, the moment it was sealed, and the paw print of the previous entry, joined by pipes. Change or drop any entry and every entry after it stops matching.

Self test

The database stamps the moment into the paw print with exactly three digits of a second. The public read api hands the same moment back with six. Keep all six and every single row fails, so this page cuts the extra digits without rounding and pads a short fraction back out to three. These cases run before the wall is read, so a broken formatter shows up here rather than as a wall that looks forged.

Every entry
waiting on the wall…

Tap any entry to see the exact text that was hashed, the moment as the api returned it, the moment as the database wrote it, and both paw prints in full.
