Resilient GPS compatible timing for distributed ledger
A system, method and apparatus in which a client computer initiates and communicates a distributed ledger transaction, said transaction labeled with a Coordinated Universal Time or UTC timestamp derived from GPS and/or GNSS satellite signals or, in the absence of GPS, an alternate source of UTC signals. The distributed ledger network nodes are able to send and receive UTC time signals even if there is a GPS and/or GNSS satellite failure.
