PublicEvidence

publicevidence.eu

Early Access

Prove. Secure. Evidence.

PublicEvidence offers a free proof of existence for documents: a timestamp anchored in a blockchain. No account is needed, and the file never leaves your device – only a fingerprint (hash) is used.

Idea & philosophy

Anyone can later verify independently that a document existed since a certain point in time and has not been altered. This is useful for contracts, drafts or inventions. The flow has four steps: choose a file, create the stamp, optionally encrypt, save or share.

Contents & features

Timestamp via hash, blockchain-anchored, no account
Secure sharing with a password and multiple backups
Make changes to documents visible
Time-lock: encryption in the browser, opening only at a chosen time via drand (League of Entropy)
Planned: official European timestamp, later paid and low-cost
German and English, light and dark mode

Status

The site carries the status “In Development – Early Access”. The same site is also reachable at publictrust.eu and trustarchive.eu.

Also reachable at: publictrust.eu, trustarchive.eu
