Abstract
Embodiments of network devices for access control are described. In some embodiments, an access control processor of a first node receives a request packet from a requestor node on an unsecured network to join a group of nodes; assigns, using a secured network protocol through the network interface, the requestor node to a first localized pool of the group of nodes within the secured network based on the received location information associated with the requestor node, wherein one or more nodes of the first localized pool are configured to perform one or more authorized modifications of data, the data comprising a blockchain including at least one cryptographic hash configured to protect the data against unauthorized modifications; and initiates the one or more first authorized modifications of the data using one or more nodes assigned to the first localized pool including the requestor node.
