Blockchain-Based Internet of Things:
Challenges and Opportunities
Tripti Paul and Sandip Rakshit
Abstract ThemajorityofinteractioninanIoT(InternetofThings)ecosystemoccurs
via Machine-to-Machine interactions. As a result, establishing confidence among
the participating equipment is a significant challenge, particularly given the fact
that IoT technology has not been adequately addressed. The Blockchain enables
autonomous smart devices and completely removes the need for intermediary parties.
However, since Blockchain enables increased scalability, security, dependability, and
privacy, it can function as a catalyst in this area. This may be accomplished by
utilizing Blockchain technology to monitor and utilize billions of devices connected
to IoT ecosystems in order to facilitate and/or coordinate transaction processing.
By eliminating a single point of failure, the implementation of Blockchain in the
IoT ecosystem will also improve reliability. The cryptographic algorithms used to
encrypt the block data and the hashing techniques can provide additional security.

Introduction
The Internet of Things (IoT) is an evolving technology that has evolved and achieved
tremendous reach without human–human workers’ involvement in science and engi-
neering applications to solve problems [1]. That makes it possible to create an inter-
action between human to machine, machine to machine, often smart working force.
A popular operating picture (COP) was made possible by the IoT through numerous
modern-day living applications [6]. The COP is done through the developments seen
in wireless sensor network systems that have connected across the network, sharing
