An Alternative to an Online Notary

An online notary witnesses your identity and signing over a webcam. If what you really need is to prove a document existed at a point in time — not to verify who signed it — a blockchain timestamp acts as a digital notary, with no appointment required.

What an online notary does

A remote online notary verifies your identity and witnesses a signing session, then applies a notarial seal. It's the right tool when a process legally requires a notary to confirm who signed.

What a blockchain timestamp does

A blockchain timestamp is a digital notary for existence: it records a fingerprint of your document on a public blockchain, proving the file existed on a date and hasn't changed since. It doesn't verify identity — it proves the document.

  • No appointment, no webcam — timestamp any file in minutes.
  • Independently verifiable — anyone can check the public record.
  • Permanent — it doesn't depend on a notary or a company staying in business.
