The Third International Workshop on Blockchain and Data Management (BlockDM 2021)

In Conjunction with ICDE 2021, April 19, 2021, Chania, Crete, Greece



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


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:
