Apparatus and methods are provided for multiple smart glasses to enter in a distributed ledger network such as a blockchain to concurrently modify documents. These networked smart glasses may store the document and any changes made to the document in a distributed ledger, communicate the changes to the other smart glasses and request approval or disapproval of the changes. Each smart glass or user may approve or disapprove the changes suggested by other users. The document may only be finalized when all suggested changes are approved or disapproved.
