Verify
Independent verification needs only public tools: sha256sum (or any SHA-256 utility) and the opentimestamps-client CLI. Both files
below come from this site; no other host or credential is required.
1. Download both files
curl -O https://www.hexetiq.com/articles/five-eras-of-ai-assisted-coding/source.md curl -O https://www.hexetiq.com/articles/five-eras-of-ai-assisted-coding/proof/attestation.ots -o 2026-05-09-five-eras-of-ai-assisted-coding.md.otsThe .ots client expects the article and attestation to share a basename, so the second command renames the downloaded file accordingly.
2. Hash the article
sha256sum 2026-05-09-five-eras-of-ai-assisted-coding.md # expected: 501bde40319e1267119d78c1e6927370a131001c3437562b8d0aaae5636c53933. Verify the attestation
ots verify 2026-05-09-five-eras-of-ai-assisted-coding.md.otsThe proof anchors to Bitcoin block 948639. Verification works offline against a Bitcoin node or block-header dataset; no calendar contact needed.
That's the full recipe. The OpenTimestamps protocol does the rest: any third party with these two files can verify the timestamp claim against the public Bitcoin blockchain. The article bytes you hash are byte-identical to the bytes that were stamped — change one character and the digest no longer matches.
