The blockchain has emerged as an innovative and powerful technology that shows the tremendous potential to enhance the smart industrial frameworks by providing encryption, immutable storage, and decentralization. In the past few years, several applications in the industrial Internet of Things (IIoT) have emerged and blockchain technologies gained great attention from academia and industry. To discover the great potential of blockchain technology for the IIoT, we present a comprehensive survey on security issues, blockchain architectures, and applications from the industrial perspective. This article starts with a comparison of exiting state-of-the-art surveys of blockchain technologies for IoT/IIoT applications. A four-layer reference architecture of IIoT is presented along with the functionalities and security issues of each layer. To address these challenges, we assess the potential of blockchain technology by considering the key characteristics, architectures, consensus algorithms, and implementation platforms. Furthermore, we also discussed some use cases of blockchain for the IIoT frameworks. Finally, this survey is concluded by highlighting some open issues and future research directions.

工业物联网区块链技术：安全挑战、架构、应用和未来研究方向的综合调查

区块链已成为一种创新且强大的技术，它显示了通过提供加密、不可变存储和去中心化来增强智能工业框架的巨大潜力。在过去的几年里，工业物联网（IIoT）中出现了一些应用，区块链技术得到了学术界和工业界的极大关注。为了发现区块链技术对 IIoT 的巨大潜力，我们从工业角度对安全问题、区块链架构和应用进行了全面调查。本文首先比较了现有的物联网/工业物联网应用区块链技术的最新调查。介绍了 IIoT 的四层参考架构以及每一层的功能和安全问题。为了应对这些挑战，我们通过考虑关键特征、架构、共识算法和实施平台来评估区块链技术的潜力。此外，我们还讨论了 IIoT 框架的区块链用例。最后，通过突出一些未解决的问题和未来的研究方向来结束本次调查。
