Welcome to Virtual-Notary - a free and secure electronic attestation service.
How does it work?
You select a factoid that you would like us to certify. We check that factoid, create a record of it that you can refer to later, and issue you a cryptographically-signed certificate that attests to that factoid. We can optionally record the certificate on the Bitcoin blockchain.
This blog post describes some of the use cases for Virtual Notary.
