Theme and Goals

This paper-oriented workshop scientifically addresses recent research efforts in the field of blockchain technology use for cross-organizational collaboration. The workshop focuses on the application of information and communication technology in order to enable organizational and governmental service provisions. The resulting technology-mediated processes are changing the delivery of private- and public services as well as the broader interactions between citizens, governments and organizations. More and more countries are considering e-governance solutions as a tool to improve the efficiency and transparency of their services. However, there exists a gap of understanding the support of trust and reputation via blockchain solutions that allow for immutable event traceability. The workshop aims for exploring systematic approaches for developing and interrelating blockchain-technology supported services, as well as increasing issues concerning blockchain-tech, enabled security and privacy of personal data use. In addition, technological advances in the field of big data analysis, blockchains for distributed application deployment, smart contracts, the Internet-of-Things, agent technologies, etc., offer new research directions in the blockchain-technology space for further improvements of existing solutions.

The goal of this workshop is to promote, establish and speed up blockchain-technology related research, and identify future research questions. Contributions should focus on clearly stated research questions covering the topics mentioned below.

The topics of interest for blockchain-technology research papers include, but are not limited to:

  • Security and Privacy Management of e-Governance Systems
  • (Smart) Government
  • E-Voting
  • Governmental Decision-making
  • E-Business
  • E-Tax
  • E-Health
  • Autonomous e-commerce
  • Identity and Identification Systems
  • Decentralized Autonomous Organization (DAO)
  • Self-Aware Contracts as well as AI and Smart Contracts
  • Open and Big Data with blockchain technology
  • Interoperability
  • Medical supply chain
  • Crowdfunding
  • Self-organizing and Evolutionary e-governance
  • Collaboration Models
  • Legal Aspects of blockchain technology
  • Benchmarks and Evaluation Strategies for blockchain e-governance Systems
  • Economics of blockchain e-governance
  • Case Studies for blockchain-based distributed applications deployment
  • Blockchain business models for Data aggregation
  • Consortium Blockchain Data Aggregation
  • Federated and Consortium blockchains
  • Blockchain Model and Data Engineering
  • Blockchain Support for Collaborative Business Processes
  • Collaborative Internet-of-Things Services for Business
  • Collaborative Smart Contracts for Enterprises Digital Identities
  • Data Management in Consortium blockchains
  • Integrated Engineering Blockchain Consortium
  • Modeling Tools and Techniques for Co-Operated Consortium Blockchain

Format of the Workshop

BIOC’21 is intended to be a full-day virtual and online workshop divided into three sessions in which around 6-8 full and 2 short scientific papers will be presented. Full papers will have a time slot reserved of 30 minutes (20 minutes for the presentation and 10 minutes for questions and discussions), and short papers will have a time slot of 15 minutes (10 minutes for the presentation and 5 minutes for questions and discussions). In addition, we plan to have a keynote speech held by an acknowledged expert in the field of blockchain technology in inter-organizational collaboration.
