SCP-089 is confined to a single Cloudflare Worker instance addressed at https://hashclaim.bisks.net/. No physical containment chamber is required. As a Safe-class object, SCP-089 may be accessed by any individual possessing a standard web browser and an internet connection; no special clearance is required for observation.
SCP-089 — designated "hashclaim" in Foundation records — classified as a utility-class anomaly, is reachable at https://hashclaim.bisks.net/.
The clearest surviving account of the anomaly's function is its own front-page copy, reproduced below:
someone posts a hash today, then posts the "source" tomorrow and claims it checks out. paste both in and hashclaim recomputes it in your browser — SHA-1/256/384/512 or MD5, auto-detected — and tells you whether the claim actually holds up.
Foundation awareness of SCP-089 began with a tagged mention from the individual on record as @bisks.net. First logged 2026-07-27.
Addendum 089-A: Personnel are reminded that Safe classification describes containment difficulty, not triviality. Do not treat SCP-089 as uninteresting on this basis alone.
