Abstract: Systems and methods for preventing invalid reverse transactions in a distributed environment is provided in which a first block is added to a first cryptographically verifiable ledger containing a transaction identifier and an executable program for preventing a reversal of a transaction. A second block is added to a second unencrypted ledger and contains a flag indicating that the transaction identifier is invalid and a reference to the first block. A notification that the transaction associated with the transaction identifier is being reversed can be received and execution of the executable program for preventing a reversal of the transaction can be triggered. In response to execution of the executable program, the reversal of the transaction associated with the transaction identifier is prevented.

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.
