Motivation

The emergence of blockchain technology has opened manifold opportunities to redesign business-to-business collaborations in a wide range of fields, including healthcare, supply chain, logistics, and Industry 4.0. Traditionally, business collaborations are executed by relying on trusted third-party providers such as Electronic Data Interchange (EDI) hubs or escrows. This centralized architecture creates entry barriers and hinders process innovation. Blockchains and smart contracts enable these processes to be executed in a distributed manner without delegating trust to central authorities nor requiring mutual trust between each pair of parties. Furthermore, blockchain technology potentially enables fine-grained access controls, allowing different parties to selectively share different data with different partners, even though all the data is resident in the blockchain.

While blockchain opens up new possibilities, it also raises a number of challenges because it requires us to re-think the way business collaborations are designed and implemented. In contrast to centralized collaborations, the transparent and decentralized nature of blockchains brings in new challenges related to compliance, control, and privacy, in addition to major scalability and performance challenges.

This Dagstuhl Seminar will bring together established and young researchers with forward-thinking industry representatives from both large and start-up companies, in order to establish a research roadmap for blockchain-based collaborative information systems, and to initiate concrete collaborations between participants along this roadmap. The seminar will address the following overarching questions:

  1. How will existing collaborative information systems be transformed by blockchain technology?
  2. What are the research challenges that need to be addressed to enable these transformations?

Specific research themes to be discussed during the the seminar include:

  • Modeling paradigms for blockchain-based information systems
  • User-friendly specification and monitoring of smart contracts
  • Synthesis of smart contracts from high-level specifications of business collaborations
  • Verification and validation of blockchain-based collaborative information systems
  • Enforcing regulations and business rules with smart contracts
  • Collaborative business process optimization on blockchain
  • Privacy models for blockchain-based collaborative information systems
  • Security requirements engineering for blockchain-based collaborative information systems
  • Linking blockchain platform properties with business and compliance goals
  • Novel business collaboration models enabled by blockchain
  • Blockchain and ethical business practices
  • Vertical applications of blockchain-based collaborative information systems (e.g. healthcare, supply chain)

The audience of the seminar will be largely interdisciplinary. It will combine academic and industrial researchers in security and privacy, blockchain technology, software engineering, databases, distributed systems, information systems engineering, business process management, supply chain management, and logistics.

The format of the seminar will combine short introductory presentations by the participants, tutorials and visionary talks, and workgroup discussions focused on specific research themes.
