Project Description
Integrates Bitcoin based Proof of Existence service in a SharePoint hosted app.


Common uses for Proof of Existence:
  • Demonstrating data ownership without revealing actual data
  • Document timestamping
  • Checking for document integrity

Gives SharePoint users the ability to prove documents from the ribbon.
Optionally, create a shared wallet, so your end-users don't have to bother with Bitcoin transactions.

App adds a button to the ribbon of document libraries on the host web
