This is the library’s own record; it lives on no third-party blockchain, by sealed covenant (no token, ever).

Verify it without trusting this page: download the raw chain and recompute every hash, or check the signed tip at /api/tip.

The public anchor stamps exactly (index, hash, sealedAt, and this page’s URL) into Bitcoin via OpenTimestamps — verify the proof with the open ots tool; no trust in this server needed. All anchors: /api/anchors.
