A Survey on Blockchain Adaptability in IoT Environments

Abstract

Blockchain is a considered to be a disruptive technology as like an Internet. The features of blockchain are giving more expectations in their applications. IoT is emerging day by day with millions of connecting devices. Even though IoT is evolving, the security of the internet of things is questionable with its architecture. IoT relay on a centralized server is vulnerable to the data breach. The trust in the centralized architecture is also questionable. We require the decentralized technology for IoT to secure their communication. The blockchain is a peer to peer, decentralized, distributed network that does not support the centralized architecture where the data are stored in the common ledger. The cryptographic hash is used in the blockchain which provides the feature of tamper-proof to the blockchain. Bitcoin is the first application that proves the security of blockchain in payment systems. Blockchain is providing transparency in the network with the shared ledger. To avoid the issues in the IoT environment the suggestion from every researcher is to go for blockchain. In this paper, we are going to survey the blockchain adaptability in various IoT environments for finding future research to improve the application of blockchain with IoT.
