IoT network processes data transactions across multiple devices owned and operated by different organizations, making it difficult to identify the source of any data leaks in the event of a cybercriminal attack.IoT can provide the data that is needed to power blockchain applications. For example, a blockchain-based supply chain management system could use data from IoT sensors to track the movement of goods throughout the supply chain. Similarly, a blockchain-based energy trading platform could use data from smart meters to facilitate the trading of energy between prosumers.
