Deepfakes
Content can be fabricated, altered, or denied. Timestamps matter more, not less.
Prove a file existed — and one day, prove you made it.
Your document never leaves your device; the receipt outlives any company.

Generative AI, deepfakes, and centralized platforms have made "what existed, when" genuinely hard to prove — and harder to trust.
Content can be fabricated, altered, or denied. Timestamps matter more, not less.
Traditional notaries are slow, expensive, and paper-era.
DocuSign & co. demand your confidential files, on a subscription, on their say-so.
Your file never leaves your device. Only a SHA-256 fingerprint is stamped — locally, in your browser.
Every claim carries a proof you verify yourself with open tools. No account. No KYC.
A portable .ots receipt anchored to Bitcoin proof-of-work verifies forever.
Your document. Your hash. Bitcoin's permanence.
Your browser computes the fingerprint. The original bytes never leave your device.
Only the 64-char hash goes to three independent OpenTimestamps calendars.
Calendars merge hashes into a Merkle tree, committed to Bitcoin.
~10 minutes later, a Bitcoin block permanently seals the commitment.
Download the .ots. Verify with open tools + a block explorer — forever.
The security comes from Bitcoin's proof-of-work — not from any company.
Higher planes evolve without ever invalidating the proofs beneath them.
Notarization & legal attestation ~$5B+/yr (still paper-era) · Legal tech ~$27B+ · AI provenance & deepfake defense: brand-new greenfield. Bitcoin-anchored zero-trust proofs have <1% penetration.
Mathematically prove a contract draft existed before a disputable date.
Hash design briefs and copy before delivery — proof of creation, secured.
Timestamp model outputs at generation for provenance and copyright defense.
One-click git-tag notarization for permanent build audit trails.
Immutable forensic snapshot of a source's content before publication.
Registry, tender & migration proof — hash-only, air-gapped friendly, no new vendor cloud.
Add your private key to an OpenTimestamps anchor and "this file existed" becomes "this file existed, and I am the one who created it."
Non-custodial — the signature lives on your key, never our server.
Verifiable by anyone, forever — no notary, no company, no permission.
Unlocks nearly every enterprise, legal & IP use case. This is the roadmap.
We show you exactly what is live, what is staged, and how to check every claim yourself.
Bitcoin + OTS anchoring, zero-knowledge hashing — true today.
LiveVerify with open tools forever. Independent client-side verify on the roadmap.
On roadmapPartial today; verified non-repudiation on the roadmap. We say so.
RoadmapBuilt & staged; launched only when the rails are funded and tested.
StagedEthereum / cross-chain is out of scope. Bitcoin is the truth layer.
BitcoinEvery proof carries a standing invitation to check with open tools.
AlwaysEvery fact surfaces when it was last confirmed. If a claim goes stale past 45 days, we mark it — honestly, in amber and in words.
Honest stale beats confident wrong. Live KPIs come from /metrics.json — never fabricated.
We never had your document.
Bitcoin's proof-of-work keeps the receipt.
Free, open tools. No account. No KYC.
