Methods, systems, and machine-readable media for adapting content composites to device operations of an endpoint media device are disclosed. Blockchain data associated with a blockchain address may be processed by one or more processing devices. The blockchain data and/or the blockchain address may be mapped by the one or more processing devices to a first endpoint media device. Based at least in part on the blockchain data, a first content composite may be identified by one or more processing devices for delivery from a content provider system via one or more networks to the first endpoint media device. Transmission of the first content composite may be caused where, consequent to delivery of the first content composite to the first endpoint media device, the first endpoint media device or a second endpoint media device performs at least one operation relating to the first content composite.
