Abstract: Systems, methods, and computer-readable storage media for identifying, via a processor, a plurality of causes for a vehicle to record data on a blockchain, wherein one cause in the plurality of causes is a repetition of a previous journey. The system generates route comparison data by comparing, via a processor as the vehicle is moving, current journey data for a current journey to previous journey data of at least one previous journey by: comparing a current journey start time to a previous journey start time; comparing a current journey travel time to a previous journey travel time; and comparing current journey route coordinates to previous journey route coordinates. Then based on the route comparison data, the system generates a side block which references the previous block in the block chain but contains only distinctions from the previous block. The side block is then added to the block chain.
