How Bernstein works

A simple web application with powerful cryptographic features. Create verifiable blockchain certificates in three easy steps.

Three steps to IP protection

Upload, certify, and prove - it's that simple.

Upload your work

Upload any digital asset - documents, code, designs, datasets. Everything is encrypted in your browser before it ever leaves your device.

Certify with blockchain

Bernstein creates a cryptographic fingerprint (hash) of your files and anchors it to the Bitcoin blockchain, along with EU and China timestamps.

Verify anywhere

Your certificate proves existence, integrity, and ownership. Anyone can verify it independently - no need for Bernstein's involvement.

Blockchain certificates

To get a blockchain certificate for any document or collection of documents, simply upload it. Bernstein crafts a special blockchain transaction containing both a cryptographic fingerprint of your IP assets and proof of your ownership.

The Bernstein registration protocol chains all certificates related to the same project together, allowing you to create a digital trail of records proving the evolution of your project over time.

Each certificate can be independently verified by any third party without Bernstein's involvement, thanks to the decentralized design of our protocol.

Important: Getting a certificate for a document does not make it public. The blockchain only contains the cryptographic fingerprint - your original files remain private.

What's in a certificate?

Cryptographic fingerprint (SHA-256 hash)
Precise timestamp (blockchain + TSA)
Proof of ownership attribution
Bitcoin blockchain anchor

Perfect confidentiality

All information and documents you submit are encrypted locally in your browser before reaching Bernstein servers. The encryption key is known only by you - it never gets sent to our servers.

Bernstein is a new kind of notary service that completely ignores the digital assets it certifies. Our team has unique experience in browser cryptography dating back to 2007, using the most advanced Web Crypto API and proven cryptographic primitives.

Zero-knowledge architecture

Thanks to Bernstein's unique zero-knowledge architecture, you can generate certificates for your digital assets without disclosing data to any third party - not even to Bernstein itself.

1
Files encrypted client-side in your browser
2
Encryption keys never leave your device
3
Only fingerprints are registered on blockchain

Multiple platforms, maximum proof

Bernstein combines the power of blockchain with official government timestamps.

Bitcoin blockchain

The most secure and immutable public ledger. Your certificates are anchored to the same network that secures billions in value.

EU qualified timestamps

Official timestamps from EU-recognized timestamping authorities, providing legal recognition under eIDAS regulation.

China TSA

National timestamps from Chinese authorities for enhanced recognition in Asia-Pacific jurisdictions.

Coming soon: Switzerland, Japan, and South Korea timestamps.

Legal acceptance worldwide

Blockchain certificates are gaining recognition in courts around the world.

Blockchain certificates are valid worldwide because they are guaranteed by mathematics, not by any central authority. The explicit admissibility of blockchain-based records and signatures is appearing in jurisdictions globally.

Countries including the USA, China, UK, Sweden, Japan, Brazil, and Dubai recognize the convenience of blockchain as a public registry. China and the USA already have legal precedents using blockchain evidence to settle intellectual property disputes.

The EU's eIDAS regulation prohibits courts from denying legal admissibility of timestamps solely on grounds that they don't meet qualified timestamp requirements.

With expert testimony, the mathematical strength of a blockchain certificate can be presented in court anywhere.
