AN IOT AND BLOCKCHAIN PERSPECTIVE

Data is stored in a distributed ledger called a blockchain,
which consists of a series of blocks. The nodes in this system make
decisions collectively, without the need for a central server. As a
general rule, a new block is constructed by taking the data from the
most recent transaction and adding it to the hash of the previous
block, if any existed. This new block is then added to the
blockchain. Once information has been added, it cannot be changed
or removed. There are two primary categories of blockchains: those
that require special access permissions and those that don’t.
Popular blockchains include Bitcoin and Ether.
Many Internet of Things use cases can benefit from
blockchain technology. One of the most important uses of
blockchain technology is in the creation of software that requires
little or no coding, such as traffic data systems, sensor data
systems, and supply chain management. When it comes to the
scalability, privacy, and dependability of the Internet of Things,
blockchain technology is the solution. For the sake of facilitating
the exchange and processing of transactions amongst billions of
connected devices, blockchain technology can be an excellent
means of tracking and monitoring these devices.
In addition, its decentralised nature would remove potential
failure points, making the resulting device ecosystem more robust.
Blockchain IoT has the potential to make it easier for devices in an
IoT network to work together safely and efficiently.
Therefore, the entirety of blockchain, its implementation in
the IoT, and its security measures will be covered in this book. This

edited volume is written in such a way that it may serve as a
textbook or reference for undergraduate and graduate courses on
blockchain.
