ABSTRACT

Blockchain is distributed digital ledger technology that facilitates reliable and transparent transactions among the participants of a system. Blockchain has been applied to various manufacturing applications and helps to create an automatic, decentralised smart manufacturing system with a high level of efficiency and productivity. This paper presents a comprehensive survey on blockchain in Industry 4.0 – applications, architectures, techniques, and research challenges. We propose a blockchain reference architecture for smart manufacturing, which guides our discussions on applying the blockchain technology to various applications of the smart factory and smart supply chain.

摘要

区块链是分布式数字分类账技术，可促进系统参与者之间可靠和透明的交易。区块链已应用于各种制造应用，有助于创建具有高效率和生产力的自动化、分散的智能制造系统。本文对工业 4.0 中的区块链进行了全面调查——应用、架构、技术和研究挑战。我们提出了一个用于智能制造的区块链参考架构，它指导我们将区块链技术应用于智能工厂和智能供应链的各种应用的讨论。
