What is a blockchain-based timestamp?

A blockchain-based timestamp is a timestamp that is stored by thousands of computers distributed around the globe. This property makes blockchain-based timestamps extremely secure and independent of a trusted third party.

What is OriginStamp?

OriginStamp is a trusted timestamping service for digital content. You can use it manually via our dashboard, or automatically via our API. For a limited usage OriginStamp is free of charge.

How is the timestamp calculated?

The timestamp represents date and time when a cryptographic fingerprint (hash) of your submitted file was included in the blockchain. For technical details, please refer to our whitepaper.

What is a timestamp certificate?

The timestamp certificate is a file that is required to prove the validity of a timestamp independent from our service. Please log in or sign up to download a timestamp certificate.

Aren't you another trusted third party?

Absolutely not. You can verify a timestamp independently and without relying on us. However, this requires a timestamp certificate. Please log in or sign up to download a timestamp certificate.

Do I have to disclose the original file?

No. The content of your files is never shared with us. The necessary hash is calculated directly in your browser on your machine. Alternatively, you can enter the SHA-256 hash of your document.
