How to check: 1. Download a file above and run: shasum -a 256 . It must print the SHA-256 shown, and that hash must appear in the list. 2. Drop the list and its .ots file on https://opentimestamps.org, or run: ots verify .ots That proves the list, and every file whose hash it holds, existed unchanged by then. Fresh timestamps reach Bitcoin within hours. More: https://tweetkeep.com/faq#proof
