A blockchain is a distributed ledger for recording transactions and/or data in a meaningful order, maintained by many connected nodes without a trusted central authority. Blockchain has a great potential to create new foundations for most distributed systems by efficiently establishing trust among nodes, especially in emerging networks. Such a fundamental technology to enable decentralization play an important role in a wide spectrum of topics such as Internet of Things (IoT), Cyber Physical Systems (CPS), edge computing, cloud computing, fog, mobile computing, social networking, wireless communication, vehicular network, and even more other fields.

At the same time, there is a lack of fundamental study on the limitation of blockchain such as scalability, security, privacy, efficiency, availability and dependability. Hence, the development and deployment of blockchain-based systems and applications will likely exhibit new requirements and complicated challenges, which brings more open issues and exciting directions for research communities.

The aim of this workshop is to bring together researchers and practitioners working in cloud computing, distributed systems, cryptography, security, and networking, from academia and industry, who are interested in the applications and theory of blockchains and related protocols.
