One system includes a first IoT device and a second IoT device configured with an active communication channel with the first IoT device and a role certificate. An operator device is configured to interact with a distributed ledger to issue and revoke role certificates for a plurality of devices including the first IoT device and the second IoT device. The first IoT device periodically validates a role certificate proof received from the second IoT device with an entry of the role certificate proof recorded on the distributed ledger.
