The idea of a fully connected digital world is quickly becoming real through the Internet of Things (IoT). This expanding network includes physical devices such as small sensors, autonomous vehicles, and industrial machines that collect and exchange data online.

Protecting this data from tampering is essential, which has led engineers to explore blockchain as a security solution. Although blockchain is widely known for its role in cryptocurrencies, its core function is as a decentralized digital ledger. Instead of data being controlled by a single organization, information is shared and maintained across many computers.
