ABSTRACT

Blockchain technology has taken on a leading role in today's industrial applications by providing salient features and showing significant performance since its beginning. Blockchain began its journey from the concept of cryptocurrency and is now part of a range of core applications to achieve resilience and automation between various tasks. With the integration of Blockchain technology into different industrial applications, many application designs, security and privacy challenges present themselves, posing serious threats to users and their data. Although several approaches have been proposed to address the specific security and privacy needs of targeted applications with functional parameters, there is still a need for a research study on the application, security and privacy challenges, and requirements of Blockchain-based industrial applications, along with possible security threats and countermeasures. This study presents a state-of-the-art survey of Blockchain-based Industry 4.0 applications, focusing on crucial application and security and privacy requirements, as well as corresponding attacks on Blockchain systems with potential countermeasures. We also analyse and provide the classification of different security and privacy techniques used in these applications to enhance the advancement of security features. Furthermore, we highlight some open issues in industrial applications that help to design secure Blockchain-based applications as future directions.

Motivation & Objective

• To address the lack of holistic research on security and privacy challenges in blockchain-based industrial applications.
• To identify and classify application, security, and privacy requirements specific to Industry 4.0 use cases.
• To analyze and categorize security and privacy attacks on blockchain systems, including their objectives and exploited vulnerabilities.
• To review existing countermeasures and privacy-preserving techniques used in industrial blockchain applications.
• To highlight open issues and future research directions for building secure, scalable, and interoperable blockchain systems in industrial settings.

Proposed method

• Conducting a state-of-the-art survey of blockchain applications in industrial domains such as IoT, finance, smart grid, logistics, and eHealth.
• Classifying application requirements into functional and non-functional categories, including scalability, usability, and modularity.
• Categorizing security attacks into types such as Sybil, eclipse, 51% attacks, and smart contract vulnerabilities.
• Mapping attacker objectives (e.g., data theft, double-spending) to specific vulnerabilities and targeted applications.
• Reviewing and classifying privacy-preserving techniques, including zero-knowledge proofs, ring signatures, and encryption methods.
• Analyzing implementation gaps and proposing future research directions based on identified limitations in current blockchain solutions.

Experimental results

Research questions

• RQ1 What are the key application, security, and privacy requirements for blockchain-based industrial applications in Industry 4.0?
• RQ2 What types of security and privacy attacks are most prevalent in industrial blockchain systems, and what vulnerabilities do they exploit?
• RQ3 How effective are existing countermeasures and privacy-preserving techniques in mitigating identified threats in industrial contexts?
• RQ4 What are the major open issues hindering the deployment of secure and scalable blockchain applications in industrial environments?
• RQ5 What design principles and requirements (e.g., scalability, interoperability, usability) are critical for future blockchain-based industrial systems?

Key findings

• Blockchain-based industrial applications face significant security and privacy challenges due to increasing user numbers and unsecured data exchanges.
• Smart contract vulnerabilities and implementation flaws are major attack vectors, especially in open-source applications.
• Scalability remains the most critical challenge, with systems like Ethereum and Hyperledger facing performance bottlenecks under high transaction loads.
• Interoperability gaps between system modules hinder real-time monitoring and coordinated security responses in industrial processes.
• Usability and flexibility issues limit broader adoption, as non-technical users struggle with blockchain’s technical complexity.
• Modularity, transparency, and extensibility are essential but often overlooked in current blockchain application designs, creating long-term maintenance and integration challenges.
