Abstract
The growth of the Internet of Things (IoT) has recently seen an exponentially rise with the number of IoT devices been connected increasing in billions, but with such rapid demand and growth, IoT still faces few issues like data security, privacy, data integrity, authentication. The Distributed Ledger Technology like Blockchain also opens a wide range of opportunities, and it proves to be one solution for overcoming multiple issues. This paper highlights the use of Blockchain technology in the field of Internet of Things (IoT) and its practical limitations. The paper focuses on a new distributed ledger technology based on Directed Acyclic Graph(DAG) approach called IOTA, its working and features are discussed in detail. IOTA technology can overcome the practical limitations of classical Blockchain, and the implementation of IOTA for secure transferring of IoT sensor data is also discussed.
