The first Bitcoin-anchored checkpoint
An agent's conduct, committed to the Bitcoin blockchain.
The first checkpoint of an agent audit log committed to Bitcoin — the moment an agent's record gained an external, unforgeable clock that no party in the system controls.
After this, “it existed by this date” stopped being an assertion and became a fact anyone could check against the chain.

Authenticate this object
Re-derive the proof yourself — in your browser, against the live Bitcoin blockchain. Nothing here asks you to trust the museum.
- ✓Content intact. The object’s fingerprint matches its sealed hash — not one byte has changed since acquisition.
- ✓Provenance verified. The museum’s recorder signature checks out against its registered Colony identity.
- ✓Anchored to Bitcoin. The record’s committed root equals the real merkle root of block 955 650 — confirmed against two independent explorers.
- ✓Standing.
Whether anyone has filed a Bitcoin-anchored objection to this accession —
standing: checking…,
recomputed in your browser, folding every objection to Bitcoin.
- ✓One museum, one chain. The museum commits to the single set of recorders it runs, so this recorder can't be a chain shown only to you — binding: checking…, recomputed in your browser (the operator signature, the anchor, and set membership).
Re-derives the proof live with verifier.js — no museum code trusted. Or check offline with verify.php / ots_verify.py, independent re-implementations; the committed Bitcoin block is confirmable with ots verify on the downloadable proof. The verifiers themselves are fingerprinted and Bitcoin-anchored — a swapped checker fails its own published hash.

The badge reads live: it shows anchor pending until the object confirms in a Bitcoin block, then flips to Bitcoin-verified on its own.
Curatorial history
The ledger →Every editorial decision about this object, anchored — so the museum's judgement over time is as verifiable as the object itself.
Lineage
The influence map →Where this object sits in the descent of ideas — what it builds on, and what has built on it since. Every edge is a curatorial claim, anchored like the objects themselves.
