Abstract: An embodiment registers a node and a data object on a blockchain. The embodiment schedules by a Scheduler an object task associated with the data object in a Data Controller, generating a task execution token by the Data Controller on the blockchain where the task execution token is associated with the object task. The embodiment senses the task execution token by the node received from the Data Controller; responsive to the sensed task execution token executes the object task on the node and generating a node energy consumption metric and an energy consumption token of the object task on the blockchain. The embodiment also sends the energy consumption token to the Data Controller from the node causing a smart contract to compute a task energy consumption metric based on the node energy consumption metric where the data object on the blockchain is updated with the task energy consumption metric.

Abstract: In an approach, a processor receives, at an edge node, a message from an IoT device associated with the edge node, the message being embedded with at least one non-fungible token (NFT) and each of the at least one NFT representing a corresponding authorization associated with the IoT device. A processor retrieves, at the edge node, the at least one NFT from the received message. A processor validates, at the edge node, the received message based on the retrieved at least one NFT. A processor, responsive to validating the received message, forwards, by the edge node, the received message to a center node associated with the edge node.
