Abstract
A system and method for managing a plurality of network-enabled client devices such as Internet of Things (IoT) and smart devices employs a distributed ledger or blockchain to store security-related information for each client device. Access to the distributed ledger is provided through a proxy computing system that is configured to exchange security-related messages with the client devices over a first communication path, which may be over a public network; and to engage in transactions with or query the distributed ledger on behalf of the client devices over a second communication path, which is a private channel Vendible data published by the client devices may be routed by the proxy computing system to a data broker or publishing system in a manner that removes identifying information from the vendible data.
