Abstract :
Blockchain is a distributed ledger and its data
immutability property solves various data security issues.
Every participant has a copy of data and validates it,
hence removing a third party to verify the correctness of
data. Smart contract is a programmatically written set of
rules that reside on the blockchain which allows the
execution of business logic when certain conditions are met
and brings in automation with trust and safety for the
data. This paper focuses on understanding blockchain, its
features, challenges, types, and how its integration can be
an advantage in IoT. The challenges faced in the
integration of Blockchain and IoT is summarized and a
study on the existing IoT-blockchain applications for
smart city is done.
