Ledger Anchor 2026-08-16
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: run
ots verify anchor_2026-08-16.txt.ots(or use the web verifier at opentimestamps.org) — confirms via the Bitcoin blockchain that this hash existed around this date. - Chain integrity: recompute the hash chain from raw ledger rows
using the recipe returned by the OneQAZ MCP tool
get_ledger_integrity, then check that the last row'schain_hashequals03e6e5bb…above. - Publication time: check this page's Wayback Machine archive for a third-party record of when it went public.
