Understanding the DocuWalk Blockchain ID

I notice that all contract signatures in DocuWalk have a Blockchain ID. What is the Blockchain ID used for?

The DocuWalk Blockchain ID shown in a blockchain signature at the conclusion of a contract signing is a component of the person's registered blockchain ID to identify them on the DocuWalk Blockchain and associate them with any contract that they have signed.

The DocuWalk Blockchain ID is only one part of many components that make up the entire blockchain registration component for all DocuWalk registered users. It is meant to be provided publicly and poses no security, privacy, or identity threat by allowing others to see or have access to it.
