Abstract:
IoT is a very fast-growing technology. IoT can be
defined as interconnected small smart devices linked over the
Internet to communicate with each other to perform meaningful
action.There are major concerns regarding the security of data
being produced from millions of devices in the IoT system.
Different security concerns in various IoT system tiers have been
covered in this study. IoT security concerns can be reduced by
using Blockchain technology, which is a decentralized distributed
ledger with several Blockchain potentials, including Persistence,
transparency, verifiability, Encryption, and operationaly strong
We review whether they make a good fit along with certain chal lenges of Blockchain that should be examined while integrating
it with IoT for resolving various security issues
