Record completeness checklist

Each row is a typed event attached to this Pith Number. Done rows show their third-party proof. Open rows have an inline form so you can complete them without leaving this page.

1 Anchor canonical hash to Bitcoin via OpenTimestamps open
Stamps the canonical SHA-256 (77496010011a672557d0da07...) across three calendars. Confirms instantly. Calendars upgrade to a Bitcoin-block proof in a few hours.
Free. No account. Anyone can re-stamp; each stamp is an independent calendar receipt.
2 Mirror to Internet Archive (Wayback Machine) open
Submits the paper URL to the Internet Archive and records the resulting Wayback capture URL plus timestamp. Pith does not host the paper.
Free, anonymous, third-party preservation.
3 Claim authorship open
Identity-backed. The same flow as the paper page. Sign in with ORCID, Apple, X, or email magic-link; if your ORCID is on the arXiv author list the attestation is one-click and shows ORCID verified.
Returns you right back here after sign-in.
4 Sign a citation pointing at this record open
Records a signed citation. Pick a relationship (supports, refutes, extends, uses_method, depends_on, replaces, compares, cites). Pith signs the assertion server-side.
More options
Held for moderation. Sign in to confirm immediately.
5 Submit replication, falsification, or formal bridge open
Public record of a replication attempt, formal bridge (Lean / Coq), or falsification. Held for moderation. Not peer review; a typed annotation.
More options
Held for moderation before it appears as confirmed.

Verify this Pith Number yourself

Three shell lines recompute the canonical hash. If the hash you compute matches the one shown above, the record is intact end-to-end.

curl -sH 'Accept: application/ld+json' https://pith.science/pith/O5EWAEABDJTSKV6Q3IDRMS7YQC \
  | jq -c '.canonical_record' \
  | python3 -c "import sys,json,hashlib; b=json.dumps(json.loads(sys.stdin.read()), sort_keys=True, separators=(',',':'), ensure_ascii=False).encode(); print(hashlib.sha256(b).hexdigest())"
