Blockchain is a decentralized transaction and data management technology that was voiced by its implementation in Bitcoin. In recent years, Blockchain has been achieving an ever-growing popularity. The reason for the interest in Blockchain is its central attributes that provide security, anonymity and data integrity without any third-party organization in control of the transactions, and therefore it is applied in numerous fields, including securing critical infrastructure.

As technology advanced, critical infrastructures increasingly come to rely on digital control systems and networking. Attacks on critical infrastructure sites are currently a fact of life rather than a potential threat. For example, power stations, chemical plants, telecommunication stations and nuclear facilities are tempting targets to cyber-attacks. In this scene, the question remains on why and how we can utilize blockchain techniques to secure critical infrastructure. Prior methods of protecting critical infrastructure have been plagued by centralized weaknesses and single points of failure problems. Contemporarily, Blockchain can offer cryptography for transactions and data in trustless distributed networks to enhance the reliability and resilience of the critical infrastructure. In other words, increasingly open and security needs is forcing us to shore up defenses with developing blockchain technology to help secure distributed critical infrastructure.

The aim of this academic get-together, ACM International Symposium on Blockchain and Secure Critical Infrastructure, is to collect latest research results concerning Blockchain and secure critical infrastructure on relevant scenarios, such as the ones subsequently listed. Researchers, experts, and scholars from both industry and academia are encouraged to share their recent studies, investigations, and findings in this forum.

The series of highly successful International Symposium on Blockchain and Secure Critical Infrastructure (BSCI) include BSCI-2020 (Taipei, Taiwan, China) and BSCI-2019 (Auckland, New Zealand).

We welcome you in Hong Kong, China, 7th June 2021!

Topics of particular interest include, but are not limited to:

Current state of Blockchain and Secure Critical Infrastructure
Blockchain Advances in 6G Network
Smart Contract Methods in Intelligent Control System
Technical issues of Blockchain and Secure Critical Infrastructure (architecture, functionality, workflows, availability, scalability, challenges of implementation, etc.)
Security and Privacy in Blockchain and Critical Infrastructure
Attacks on Blockchain and Critical Infrastructure
Blockchain and Secure Critical Infrastructure with Smart Grid
Blockchain and Secure Critical Infrastructure with Industry 4.0
Impact on business models (change of existing business models, emergence of new business models, disruptive business models, etc.)
Blockchain Advance in Secure Smart Grid
The future applications of Blockchain and Secure Critical Infrastructure in different areas (finance, insurance, healthcare and pharmaceuticals, energy sector, education, transportation, media production, government sector etc.)

In addition to the technical research achievements, all qualified submissions in relevant subtopics (including novel industrial topics) not mentioned here are welcomed, too. Nevertheless, articles focusing on describing standards or commercial purposes are not considered as acceptable contents for this symposium. High quality submissions will be recommended to a few journal special issues that are currently being applied for.

Selected high-quality papers will be suggested to the following special issue:
Blockchain: Research and Applications (Elsevier), Special Issue on Blockchain and Secure Critical Infrastructure (BSCI)
