Abstract
A distributed secured database system includes a ledger, a transmitting device, edge devices, and a time synchronization source. An evolving nonce is generated at the transmitting device and the edge devices. The evolving nonce is time-synced across the transmitting device and the edge devices. A hash value is generated at the transmitting device and the edge devices using the evolving nonce. The hash value is verified at the transmitting device and each of the edge devices during a particular time frame. A block is added to the distributed secured database system when the hash value is verified by the transmitting device and the edge devices.
