C A L L - F O R - P A P E R S The Third International Workshop on Blockchain and Data Management (BlockDM 2021) In Conjunction with ICDE 2021, April 19, 2021, Chania, Crete, Greece https://blockchain.comp.hkbu.edu.hk/blockdm2021/ Overview Blockchain has been emerging as a potential technology to disrupt traditional database systems. Over the past decade, it has found numerous applications in finance, IoT, healthcare, supply chains, digital copyrights management, and so on, and is becoming a hot research area. In contrast to traditional database systems, blockchain is decentralized, immutable, and cryptographically secured, where no single entity has full control. This new technology has significantly changed data access, storage, retrieval, and information discovery. It presents many fundamental research challenges for the management of data in the blockchain. This workshop aims to bring together researchers and practitioners working on blockchain systems from different data management aspects, including storage management, fault tolerance, query processing, information discovery, transaction management, security, and privacy. We encourage papers that apply ideas and techniques from different areas to understand the problems and challenges in blockchain systems and propose innovative solutions. We also welcome papers that report novel systems and applications built with blockchain technology. Topics of interest include, but are not limited to, the following: Blockchain data management Blockchain data provenance Blockchain consensus and fault tolerance mechanisms Blockchain system design and performance optimization Blockchain storage management Data security, privacy, and trust in blockchain Information retrieval on blockchain Data mining and knowledge discovery on blockchain Query processing on blockchain Transaction management on blockchains Smart contract and distributed ledger Domain applications of blockchain in finance infosec SUBMISSION GUIDELINES We solicit submissions of original papers that are not being considered for publication elsewhere. Both regular papers and short papers (reporting work in progress, providing system experience, or suggesting possible research directions) are welcome. All submissions need to follow IEEE Computer Society Proceedings Manuscript Formatting Guidelines. See templates here. The followings are the page limits: Regular paper: 6-8 pages Short paper: 3-4 pages ORGANIZATION Workshop Chairs: Yuzhe Tang Syracuse University, New York Jianliang Xu Hong Kong Baptist University, Hong Kong Demetrios Zeinalipour-Yazti University of Cyprus, Cyprus Program Committee: Amr El Abbadi, University of California - Santa Barbara Mohammad Javad Amiri, UCSB Manuel Bravo, IMDEA Software Institute, Madrid Yang Cao, Kyoto University Jinchuan Chen, Renmin University of China Tien Tuan Anh Dinh, Singapore University of Technology and Design Yue Duan, Illinois Institute of Technology Davide Frey, INRIA Cheqing Jin, East China Normal University Chao Li, Beijing Jiaotong University Kai Li, Syracuse University Balaji Palanisamy, University of Pittsburgh Zhe Peng, Hong Kong Baptist University Ravi Ramamurthy, Microsoft Mohammad Sadoghi, University of California, Davis Felix Martin Schuhknecht, Saarland University Xusheng Xiao, Case Western Reserve University Cheng Xu, Simon Fraser University Mu Zhang, University of Utah Zhiwei Zhang, Beijing Institute of Technology IMPORTANT DATES Paper Submission: Jan 25, 2021 Result Notification: Feb 22, 2021 Camera Ready: March 1, 2021 Workshop Date: April 19, 2021
