Brief overview of Blockchain and IoT

Blockchain is a decentralized, distributed ledger technology that ensures secure and transparent record-keeping through a chain of linked blocks. Each block contains a timestamped list of transactions, and once added, it cannot be altered without changing subsequent blocks, providing immutability and integrity.

The Internet of Things (IoT) refers to the network of interconnected devices embedded with sensors, software, and other technologies, enabling them to collect and exchange data. IoT aims to enhance efficiency, automation, and communication by allowing these devices to interact with each other and the external environment.

When combined, Blockchain and IoT create a powerful synergy by leveraging the security features of Blockchain to enhance data integrity, traceability, and automation in the vast ecosystem of interconnected devices represented by the Internet of Things.
