PayCensus Operations & Audit
MACHINE-READABLE
Every collector run is recorded — cursor reached, items ingested, processing time, errors.
This page and the underlying JSON are public on purpose: the census is only as good as its audit trail.
Raw counters below are cumulative since 2026-10-31 (history starts at launch, never backfilled).
Proof of Integrity · hash-chained & anchored to Bitcoin via OpenTimestamps
| Snapshot | Chain digest (SHA-256) | Status | BTC block | Verify |
|---|
Every day the three public data files are snapshotted, and the snapshot's hash — chained to the previous
day's hash — is anchored into the Bitcoin blockchain via OpenTimestamps. This proves, cryptographically,
that the published history has never been rewritten after the fact: altering any past day would break
every subsequent link. $0 cost, no account, receipts are third-party verifiable
with ots verify or verify.opentimestamps.org. Receipts (.ots) are binary proofs — they look empty in a browser; click info for a human-readable summary.
