Public verification · review
This review is signed and unaltered.
Authyr signed this review against a recorded visit, and each end of its history below is independently signed — the rating cannot be altered after the fact. How that visit was recorded is shown just below.
How the visit was recorded
A signal is one independent piece of evidence that the visit happened, recorded at that moment by a system the business can’t edit afterwards. Verified means the visit is backed by a payment, or by two signals from separate systems, like a counter scan and a booking. What each signal means
Resolution arc
The original 2★ and the final 4★ are each signed into Authyr's hash chain. The recovery is provable — not editable.

Once an hour, Authyr folds the fingerprints of its newest signed records into one fingerprint and writes it to Bitcoin through OpenTimestamps, a free public service. This review is inside a batch that Bitcoin has confirmed.
For the business
Your records are evidence that does not depend on trusting Authyr. Anyone can prove this review existed by that time and that nobody, Authyr included, rewrote or backdated it.
For the customer
What you wrote is what stays. Only a fingerprint is anchored: your words, rating and name never leave Authyr for this.
This proves the record was not altered after it was sealed. It does not judge who wrote it; that is the job of the recorded visit and the capture checks.

Fetch the public key from https://authyr.com/.well-known/keys/2026/public.json. For each end above, recompute the hash named in hash_alg (today SHA-256) over the canonical JSON of { review, hashAlg, prevHash, publicKeyId } (prevHashis that end's chain-prev value; entries signed before June 21, 2026 omit hashAlg) and verify the ed25519 signature against that hash.
