Abstract: A distributed ledger server includes a memory to store a database of network locations associated with registered network devices, the network locations each indexed against a public key and a hardware fingerprint. A processing device is coupled to the memory and is to: receive a request from a first network device to look up a public key and a second hardware fingerprint for a second network device with which the first network device requests to communicate; authenticate the first network device based on at least the network location of the first network device and as having previously registered; retrieve the public key and the second hardware fingerprint that are indexed in association with the second network device; and respond, to the request to the first network device upon successful authentication of the first network device, with the public key and the second hardware fingerprint.

Abstract: A wireless router dissipates heat through use of a unique heat sink having tines to increase the heat sink surface area. A housing includes lower vents and an upper vents to enable passage of an airflow. The airflow may be generated by one or more fans disposed within the housing interior. The heat sink is disposed in proximity to the upper vents and above a transceiver and an amplifier to thereby receive and dissipate heat. The wireless router is able to effectively dissipate heat generated by the transceiver and amplifier which allows for increased power output.
