Paste the exact final text of your post below — the way you're about to publish it, without the footer line. This fingerprints it (SHA-256, computed in your own browser) and seals that fingerprint into the live audit chain. Change even one letter afterwards and it will no longer match.
How this works: your text never leaves your browser — only its fingerprint is sealed. Once sealed, add the verification line it gives you to the end of your post before publishing, so readers can check it at sebbi.pro/verify-post.
