Emerging technologies such as blockchain and digital twins are essential for the rapid development and employment in Industry 5.0 revolution. With the growing number of industrial IoT nodes, optimizing the network and availing of limited resources to enable secure transmission is difficult. A digital twin is the virtual representation of a physical device that completely depends on sensor data for the critical decision-making simulation process. To this end, we combine a blockchain-based distributed network with a digital twin for the Industrial Internet of Things (IIoT) applications. This paper proposes a blockchain-based Proof of Authority (PoA) trust mechanism to provide high-quality services such as security and data privacy in IIoT. Furthermore, to enhance the authority of decentralized digital twin combined blockchain networks, we introduce a Deterministic Pseudo-Random Generation (DPRG) to generate a genesis block. To evaluate the trustworthiness of the proposed system, we simulate the blockchain network with a digital twin using IIoT sensor nodes. The simulation result shows that the PoA-based authority master nodes can reduce energy consumption and enhance data security.

区块链、数字孪生等新兴技术对于工业5.0革命的快速发展和就业至关重要。随着工业物联网节点越来越多，优化网络和利用有限资源实现安全传输变得越来越困难。数字孪生是物理设备的虚拟表示，它完全依赖传感器数据来进行关键决策模拟过程。为此，我们将基于区块链的分布式网络与工业物联网 (IIoT) 应用程序的数字孪生相结合。本文提出了一种基于区块链的权威证明（PoA）信任机制，以在工业物联网中提供安全和数据隐私等高质量服务。此外，为了增强去中心化数字孪生组合区块链网络的权威性，我们引入确定性伪随机生成 (DPRG) 来生成创世块。为了评估所提出系统的可信度，我们使用 IIoT 传感器节点通过数字双胞胎模拟区块链网络。仿真结果表明，基于PoA的权限主节点可以降低能耗，增强数据安全性。
