Prove. Secure. Evidence.

Your document gets a stamp that no one can change unnoticed.

Start for free, no account required. Your file stays with you, we only see a fingerprint. Later anyone can verify it's unchanged and when it existed.

Why PublicEvidence

Robust. Simple. Affordable.

Simple

Choose a file, press a button, done. No technical knowledge needed.

Affordable

The basic proof is free. An official timestamp will cost little later.

Robust

Your proof works even without us. You're not dependent on a provider.

Process

Secured in four steps

1

Choose file

Select a document on your device. It won't be uploaded.

2

Get stamp

Your document gets a timestamp that cannot be changed unnoticed.

3

Encrypt if desired

Set a password. Encryption happens on your device, not with us.

4

Save and share

Keep copies in multiple places or share your document with a password.

Applications

Five ways to secure evidence

Prove you had something

Later prove your document existed at a specific time. For contracts, drafts, concepts or invention ideas.

Publish and share securely

Share content with a password. Recipients can verify nothing changed since publication.

Secure important things multiple times

Keep copies of important documents in multiple places. If one fails, others remain.

Make changes visible

The proof is anchored in a public, decentralized register. Changes are noticed immediately.

Official timestamp

A certified European provider confirms when your document existed. For especially important cases.

Your data

Your data stays yours

You encrypt yourself. Encryption happens on your device.

You set the password. You decide who gets access. We don't know it.

Unencrypted data never reaches us. We don't see your content.

We publish only what you want. Nothing happens without your consent.

You're not dependent on us. Your proofs can be verified without PublicEvidence.

If you lose your password, neither we nor anyone else can open your encrypted files. Keep it safe.

Your device

Your file. Your key.

Scope: what we offer and what we don't

Your proof proves
Your proof does not prove
  • The file existed at least by this time.
  • It hasn't been changed since. Any change is noticeable.
  • Anyone can verify it, even without us.
  • The content is true.
  • Who created the file or who owns it.
  • That a court will accept it in every case.
  • That a scan replaces an official original.

Frequently asked questions

FAQ

The most important questions at a glance. You can show or hide the entire FAQ section.

Do I need to register?

No. The free proof works without an account.

Will my file be uploaded?

No. For simple timestamping it stays on your device. Only a fingerprint is transmitted.

What happens to my unencrypted data?

It never reaches us. If you store content, it's encrypted on your device first.

Can I change or delete a proof later?

No. Once anchored, proofs cannot be silently changed, and distributed copies are hard to retrieve.

Is this an official timestamp?

The free proof is a technical blockchain proof. An official timestamp from a certified EU provider is planned.

Does this replace certification or legal advice?

No. Please consult a qualified person about whether a proof can be used in your specific case.
