## Abstract

Devices, systems, and methods for providing software to aircraft using a distributed ledger are disclosed. A software delivery system includes aircraft having an engine control system configured to verify and install software utilized by components of the aircraft, an electronic distribution system coupled to the aircraft, an edge manager coupled to the electronic distribution system, and computing devices acting as nodes in a distributed ledger base maintaining a distributed ledger. The electronic distribution system verifies a request for software, requests software, and initiates an installation protocol with the engine control system. The edge manager maintains software. The distributed ledger base is coupled to the aircraft, the electronic distribution system, and the edge manager. The distributed ledger provides a record including information pertaining to a request for software, verifications of the request by the electronic distribution system, the edge manager, and the engine control system, and an installation of the software.
