Programm des Dagstuhl Seminars [pdf]


Blockchain-based applications such as Bitcoin or Ethereum are emerging technologies, but a dramatic increase in industrial and academic interest in the technology is evident. Start-­‐ups and large financial players are working intensely on blockchain-based applications, making this one of the most promising drivers of financial innovation. However, the design and implementation of blockchain-based systems requires deep technical know-how;how in various areas, as well as consideration of economic and societal issues.

These opportunities and challenges provide the starting point for the Dagstuhl Seminar where we will analyze and synthesize the current body of knowledge on the emerging landscape of blockchain technologies. We link cryptographic economic systems to already established research streams around trust-related issues in payment systems and digital currencies, and digital asset management.

The seminar aims for creating a research roadmap and prioritized agenda for the international scientific community concerned with investigating blockchain bases developments. The seminar provides a venue to present findings, develop research collaboration and debate the risks and opportunities of blockchain technology and related services. As the seminar is addressing leading edge developments, weespecially encourage studies of innovative services created. We seek research position statements, case studies, and practitioner reports related to blockchain followed by new service development and their implications.

Topics include but are not limited to:

  • Actors in blockchain value chain
  • Transformation of novel currencies to old currencies
  • Standards and interfaces related to blockchain
  • New payment and smart contract platforms
  • Blockchain developers and communities
  • Business model destruction/creation caused by blockchain and smart contracts in general
  • Novel approaches to development of blockchain applications
  • Legal issues with smart contracts
  • Relationship and interplay of open source and blockchain technology
  • Challenges of implementing business logics in smart contracts
  • Limits of blockchain applications in large distributed transaction systems
  • Implications for existing and rise of new business models
