Blockchain

A blockchain is a decentralized and distributed ledger technology that provides a secure and transparent way to store and exchange information. This can help address concerns around data privacy and security in IoT by ensuring that all data exchanges are verified and recorded in a transparent and immutable way.One potential use case for blockchain in IoT is in supply chain management, where it can be used to securely track the movement and ownership of goods as they move through the supply chain. Another use case is in energy management, where a blockchain can be used to create a peer-to-peer energy trading network that securely tracks energy transactions between IoT devices.Overall, blockchain technology can be a powerful tool in addressing IoT security and privacy concerns by creating a secure and transparent network for IoT devices and data.
