Block Notary

the App allows you to store the digital fingerprint of your files in the public ledger called “The Blockchain”.
Think of it as a notary for the digital age. The App is as simple as clicking the “Share” button.

Block Notary

your "proof-of-existence" app

After you download the "Block Notary" app you can store the digital fingerprint of any content from your phone in the most secure and reliable public ledger ever created by humankind—the Blockchain.

You can use it like a copyright to verify your rights to photo, video or any clipboard content that you created. 

We use Bitcoin Bitcoin TestNet3, BlockCypher Test. We will add Bitcoin Livenet, Factom and other services in future versions.
