Blockchain Timestamp vs Notary

A notary public or Justice of the Peace and a blockchain timestamp answer different questions. A notary confirms who signed something, or that a copy matches an original they were shown. A TimeBind proves that a specific digital file existed by a point in time and has not changed since.

Proves authorship or truth?Confirms signer identity, not content truthNo; timing and integrity only

When you need a notary

  • Documents for use overseas, including apostilles
  • Statutory declarations and affidavits that must be witnessed
  • Certified copies requested by a bank, court or agency

When a TimeBind helps

  • Proving when photos, recordings or drafts existed
  • Showing a contract, report or file has not been changed since a date
  • Large or numerous digital files that a witness could never inspect
  • Recording evidence quickly, before it can be challenged

What a TimeBind proves, and what it does not. A TimeBind proves that your file existed no later than the time it was recorded on the Bitcoin blockchain, and that it has not changed since. It does not prove who created the file, that its contents are true, or that a court will admit it. It is independent evidence of timing to use alongside your other records, and it is not legal advice.

Frequently asked questions

Can a notary prove when a digital file was created?

Not directly. A notary or Justice of the Peace can witness signatures and certify that a copy matches an original shown to them on a date. They do not check a digital file’s contents byte for byte later on.

Does a TimeBind replace a notary?

No. If a document must be witnessed, notarised or apostilled, you still need that. A TimeBind adds independent, checkable proof of when your digital files existed and that they are unchanged.

Can I use both?

Yes. For example, TimeBind the signed PDF after the notary appointment to show that the file you hold today is the same one that existed then.
