List history
Public lists change quietly. Checked hourly: when one of these files changes, we keep a copy and put its SHA-256 in our witnessed, Bitcoin-anchored log. Anyone can later show what a list said on a given date: hash the copy, open its receipt.
Started 17 October 2026. A version that appeared and disappeared between two hourly checks is not seen. Updated 2026-10-19 20:20 UTC.
