Techniques are described herein for securely managing and tracking UAV flight paths. The techniques include receiving a flight plan from an unmanned aerial vehicle (UAV). The UAV comprises a memory unit for storing a key associated with the UAV. The key enables the UAV to add one or more blocks on a blockchain distributed ledger, wherein the flight plan comprises one or more legs of a flight path. The techniques further include receiving, from the UAV, a block indicating that the UAV completed at least one leg of the flight path. The block can include a hash associated with the at least one leg of the flight path. The block is validated based at least on the hash associated with the at least one leg of the flight path and if the block is validated, a success notification is transmitted to the UAV to continue executing the flight plan.
