Proof of existence

Content sealed by its fingerprint

hash-only · content never uploaded

Only a SHA-256 fingerprint was submitted — the content itself never left the author's machine. This record proves that content with this exact fingerprint existed at 10/5/2026, 12:56:41 AM, sealed with a 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.
