Ledger Anchor 2026-10-04
This page is the weekly integrity anchor for the OneQAZ prediction ledger.
The hash below is cryptographically linked to the ledger's entire history:
if any ledger row is edited or deleted after this page was published, a
recomputed chain hash will diverge from this one. The accompanying
.ots file proves this hash was timestamped on the Bitcoin
blockchain (anyone can verify it at
opentimestamps.org).

How to verify
- Timestamp:
ots verify anchor_2026-10-04.txt.ots(or verify on the web at opentimestamps.org) — confirms on the Bitcoin blockchain that this hash existed around this date. - Chain integrity: using the recipe returned by OneQAZ MCP
get_ledger_integrity, recompute the hash chain from the raw ledger rows and check that the last row'schain_hashmatches2235905a…above. - Publication time: confirm the publication time from a third-party record via this page's Wayback Machine archive.
