Abstract
A system and method providing Proof of Location or Proof of Location and Velocity consensus in a blockchain network using radio frequency (RF) signals. Nodes validate the location of other nodes in the network using PING-PONG round trip signal propagation time to determine maximum distances to other nodes. These maximum distances are then shared between nodes, whereupon the nodes use computational techniques to resolve validated, geospatial location of the other nodes. The sharing of measured maximum distances to local nodes is a form of Proof of Location consensus. The validated geospatial locations (and velocities) of local nodes are then written to the blockchain, creating a time history for each node. This information may be used by the blockchain operating rules to implement any number of security and other operational functions. The ability of the invention to operate without need for time synchronization between nodes is an advantage of the system.
