Abstract: Internet of Things (IoT) growing at a rate of exponential numbers in recent years has received extensive attention with Block Chain (BC) technology which provide trust to IoT with its immutable nature, decentralization in computing, resource constraints, security and privacy. The distributed ledger of transactions in BC is path leading technology for addressing Cyber Threats in the form of data theft; it provides secure application architecture which has proven track of record for securing data. IoT devices using BC enabled to communicate between objects, share data, decide based on business criteria and act as a medium to securely transmit information. This work provides lightweight BlockChain with two prominent consensus mechanism PoW – Proof of Work and PoS – Proof of Stake for smart IoT devices. Next, Smart Home Device (SMD) is ensures providing best-in-class Security and Privacy for smart home Appliances. Further provides future advances in the Approach.
Keywords: Blockchain, Decentralization, Consensus Mechanism, Smart Home Device, Security and Privacy.
Scope of the Article: Blockchain-enabled IoT Device and Data Security and Privacy.
