Lawyers dealing with confidential documents can now use Stampery, a document certification service, to send files to notaries. Stampery employs secure zip files to handle documents, which ensures that documents on the blockchain cannot be tampered with in any way. Stampery encrypts all content so that it is only available to its intended user, and the service allows users to upload government ID’s to make digital notarization possible.

Stampery is free for users uploading less than ten documents per month, with a monthly fee for up to 1,000 items. The blockchain system is still in the works, including a new email flagging system, and the company just received more funding to enhance the services available to its users.
