How to verify this record

Publishing "what I have done" is cheap. What is expensive is letting a reader confirm that the same person really did it, in that order, over that time. Three mechanisms do that here.

1. Hash chain: the head tells you if the body changed

At build time every published entry is sorted by date and chained: each digest = SHA256(previous digest | index | file id | ISO8601 date | title | full body). Change a title, a date, or one character of prose, and every digest after it — including the head — changes. The summary field used in listings is not hashed.

Stated limits: this proves nothing was edited after publication. It cannot prove the writing is true. The head is stamped by a Cloudflare Pages deployment; the source sits in Git (the footer names the commit this content was built from). Together they form checkable time evidence.

2. Deployment time: the content is stamped by the platform

The site is a static build; deployment output cannot be rewritten server-side. What you see matches the files a given deployment uploaded, and the page footer names the commit that produced it.

3. External anchors: one person, several places

• GitHub: github.com/OwenJiong24 — public commit history is the hardest engineering evidence.
• Source of this site: github.com/OwenJiong24/personal-site — the footer names the commit this page was built from. Check that commit out, run 'pnpm build', and the chain head in the footer should match: a reproducible anchor, not a claim.
• Email: [email protected] — the domain is mine and receives mail.
• RSS: /rss.xml (English feed) — aggregators can archive it externally.

Not done yet (stated plainly)

• Periodically anchoring the head somewhere immutable (a public repo, an RFC3161 timestamp authority).
• Signing the head with a private key and publishing the key fingerprint.
