docuProof turns any file into a permanent, Bitcoin-anchored certificate that proves it existed, unchanged, at a specific moment in time. No accounts, no seed phrases — just upload, pay, and keep your receipt.
Paper burns. Theft happens. Servers crash. The Bitcoin blockchain never forgets.
docuProof creates a secure digital fingerprint of your file—stored permanently on Bitcoin’s public ledger. Until now, proving you had something first usually meant emailing it to yourself, mailing a sealed envelope, or trusting a platform that might disappear. docuProof gives you a cryptographic receipt anchored to Bitcoin’s public ledger — a neutral third-party record that does not depend on docuProof continuing to exist.
Timestamp work-for-hire contracts or creative drafts before sending to clients.
Timestamp manuscripts, scripts, songs, treatments, or artwork before you pitch, collaborate, or publish.
Protect lab results, datasets, or thesis drafts for academic priority.
Immutable proof for contracts, NDAs, directives, and compliance records.
Your file never leaves your device.
We generate a unique SHA-256 code like digital DNA.
The fingerprint is permanently logged in Bitcoin’s immutable record.
Complete payment and receive your verifiable certificate instantly.
Timestamp files in seconds—no lawyers or waiting. Immediate certificate of existence.
Your file’s fingerprint is anchored on Bitcoin. Anyone can verify it anytime—no trust required.
Professional-grade document security for just a few dollars per file.
One document, one permanent blockchain anchor, instant certificate.
Monthly plans billed monthly. Annual plans billed upfront. Proof allocations reset monthly. Unused proofs don’t roll over.
No. docuProof creates a cryptographic proof-of-existence, not a notarization. It verifies that your file existed at a specific time and has not changed since.
No. Your file never leaves your device. We hash it locally in your browser and only submit the SHA-256 fingerprint for blockchain anchoring.
Only your file’s cryptographic fingerprint (a 64-character SHA-256 digest). It cannot be reversed or used to reconstruct the file. Your document’s contents always remain private.
Your certificate and Proof ID are issued instantly. Bitcoin anchoring depends on network activity and occurs asynchronously. Your certificate includes a link to live status and confirmations.
Save your original file and the PDF certificate you receive. Together they allow anyone to independently verify your proof at any time — with or without docuProof.
Almost anything: PDFs, images, videos, text files, manuscripts, contracts, research notes, artwork, audio files, and more. If it can be hashed, it can be proven.
Bitcoin provides the most secure, neutral, globally replicated ledger for proof-of-existence. Its immutability and longevity make it the preferred chain for long-term evidence.
Yes. Your certificate includes everything needed to verify independently using OpenTimestamps and your original file. docuProof is not a point of failure.
Secure your work in under 60 seconds with a permanent, independent proof.
