blockchain technology is regarded as the emergent security solution for many applications related to the Internet of Things(IoT).In concept,blockchain has a linear structure that grows with the number of transactions *** growth in size is the main obstacle to the blockchain,which makes it unsuitable for resource-constrained IoT ***,conventional consensus algorithms such as PoW,PoS are very computationally *** paper solves these problems by introducing a new lightweight blockchain structure and lightweight consensus *** multi-zone Direct Acyclic Graph(dag)blockchain(multizone-dag-blockchain)framework is proposed for the fog-based IoT *** this context,fog computing technology is integrated with the IoT to offload IoT tasks to the fog nodes,thus preserving the energy consumption of the IoT *** IoT and fog nodes are initially authenticated using a non-cloneable physical function-based validationmechanism(DPUF-VM)inwhichmultiple authentication certificates are verified in the *** transaction is stored in a hash function in the blockchain using the lightweight CubeHash algorithm and signed by the Four-Q-Curve *** the cloud,sensitive data is stored as *** nodes provide data security to avoid the energy consumption and complexity of IoT *** fog node first performs a redundancy analysis using the Jaccard Similarity(JS)measure and sensitivity analysis using the Neutrosophic Neural Intelligent Network(N2IN)algorithm.A lightweight proof-of-authentication(PoAh)algorithm is presented and executed by the optimal consensus node selected by the bi-objective spiral optimization(BoSo)algorithm for transaction *** proposed work is modeled in Network Simulator 3.26(ns-3.26),and the performance is evaluated in terms of energy consumption,storage cost,response time,and throughput.
