The only information which is stored on the blockchain is your unique document checksum and the time in which the document was signed. No personally identifiable information is stored, and you are the only one who knows the checksum which can be used to validate the authenticity of the document as well as the timestamp in which it was minted. 

Digital signatures are transforming the way we work. Join us on this mission to reinvent the age-old concept of document signatures, and embrace new business opportunities!
