1. A method comprising:
providing, by a first device to a node in a network of nodes, operational data, wherein the nodes in the network of nodes are Internet of Things (IoT) devices, and wherein the first device causes writing of the operational data to a first blockchain;
determining, by the first device, a first device action;
generating, by the first device, a message comprising the first device action;
broadcasting, by the first device to the nodes in the network of nodes, the message comprising the first device action, wherein the nodes in the network of nodes determine whether the first device action is valid by using a consensus algorithm, wherein the consensus algorithm determines that the nodes in the network of nodes agree that the operational data is consistent with the first device action;
causing, by the first device, writing of the first device action to a second blockchain; and
executing, by the first device, the first device action.
