Proof of existence

Content sealed by its fingerprint

hash-only · content never uploaded

Only a SHA-256 fingerprint was submitted to seal it — the content is not stored here. This record proves that content with this exact fingerprint existed no later than 10/19/2026, 2:44:00 AM, sealed with an independent timestamp and anchored to Bitcoin. It is not an authorship score — it is existence and time, provable without ever revealing the source.

Anyone can put a certificate on trial. Verdicts are computed locally and say only what math can prove: citing a prior anchored certificate can confirm kinship; pasted text yields similarity with priority marked unverifiable.

Download the sealed record and the .ots file into one folder and run ots verify deusproof-c5f66e32-c3bb-4a9d-b7c1-a8a9d3f0add1.ots (or drop both at opentimestamps.org). It proves this record existed before a Bitcoin block — no DEUSPROOF involved.
