This paper proposes an energy efﬁcient and highly secured blockchain based industrial internet of things (IIoT) system, which is distributed in nature and offer a new direction for the development of IIoT network. Typical IIoT model is based on the centralized architectural scheme, however it is fragile in terms of power consumption and secured transaction, where blockchain can be a possible solution. In this paper, we give the solution of data security and efﬁcient power consuming mechanism through modiﬁed proof-of-work (PoW) mechanism and proper data integration mechanism. This paper analyses the dissimilar impact of IoT technology in the area of artiﬁcial intelligence. Finally the simulation results show that blockchain based IIoT scheme is more efﬁcient than traditional static architecture in terms of throughput, latency, and security.
