Proof of Existence Guide

With blockchain, you can create entries to prove that data existed in a certain state at a certain time. From that point on, anyone with access to the data can verify it against the blockchain version. Future changes to the data will show up like a sore thumb and can be detected quickly by any Connect-enabled system.

When using Proof of Existence to sign and store a timestamp of a file or data proof, and be able to  authoritatively show it has not changed, the world becomes a more trusted place.
