The first Workshop on *Blockchain for Trustworthy Industry 4.0 (BlockTrust 4.0)* Collocated with *The Fourth International Conference on Blockchain Computing and Applications (BCCA 2022)* (*http://intelligenttech.org/BCCA2022/Workshops/BlockTrust2022/ <http://intelligenttech.org/BCCA2022/Workshops/BlockTrust2022/>*) 5-7 September 2022 (San Antonio, Texas, USA) (http://intelligenttech.org/BCCA2022/index.php) *Scope and topics of the workshop:* Today, blockchain is no longer a tool that is only used for cryptocurrencies. Blockchain has become a disruptive technology that is providing support to a plethora of sectors. The financial, governmental, industrial and health sectors will benefit tremendously from blockchain. The industrial revolution has gone through multiple phases to improve the manufacturing and distribution process of products and services. Industry 4.0 focuses on interconnectivity, automation, machine learning (ML), and real-time big data. The shift towards Industry 4.0 requires cooperation among Internet of Things (IoT) devices through secure and intelligent mechanisms. Artificial Intelligence (AI) will with no doubt play a significant role in the ability of IoT devices to be part of the service provisioning process for all Industry 4.0 sectors. To ensure the integrity, reliability, and security of the transactions performed by the intelligent IoT devices in diversified ecosystems, a decentralized trustworthy solution is crucial. Blockchain technology provides a mechanism to enable distributed and decentralized transaction authentication in self-configurable and self-manageable IoT environments. In this context, the goal of this workshop is to elaborate and emphasize the key aspects of the use of blockchain for Industry 4.0. The workshop aims at bringing together developers, academics, and professionals interested in blockchain technology for the advancement of Industry 4.0. The workshop welcomes original research and innovative solutions, and may focus on either fundamental methodological studies or use cases and application demonstrations. Authors are invited to submit original research contributions that fall into or are related to the topic areas listed below: · Blockchain-enabled Industry 4.0 architectures and frameworks · Decentralized and distributed industrial data storage in blockchain · Blockchain-enabled robotic communication · Blockchain-supported economic industrial models and paradigms · Health 4.0 architectures and frameworks · Federated learning and blockchain for secure Health 4.0 applications · AI and blockchain for trustworthy Health 4.0 · Securing critical Industry 4.0 infrastructures with AI and blockchain · Blockchain-specific scalability and performance issues in Industry 4.0 · Cross-chain ecosystem for Industry 4.0 · Industrial consortium governance and ownership models · Blockchain-based AI tools and simulators for industry 4.0 · Securing industrial smart contracts with blockchain · Blockchain-supported Industry 4.0 communication and networking · Applications of blockchain technologies in Industry 4.0 · Blockchain-enabled energy trade *Steering Committee:* *Prof. Khalid Al-Begain*, Kuwait College of Science and Technology, Kuwait. *Prof. Hussein Mouftah*, University of Ottawa, Canada. *Organization Committee:* *Dr. Ismaeel Al Ridhawi*, Kuwait College of Science and Technology, Kuwait. *Dr. Safa Otoum*, Zayed University, Abu Dhabi, UAE. *Dr. Nadra Guizani*, University of Texas at Arlington, USA. *Important Dates:* Workshop Papers Due: *25 June 2022* Papers Acceptance Notification: *1 August 2022* Final Camera-Ready Paper Due: *15 August 2022*
