human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "exploring the added value of blockchain technology for the healthcare domain"):
  Abstract: In this report, the University Medical Center Groningen (UMCG) has written down lessons learned on how blockchain technology can have an impact on the healthcare domain. By looking at two use-cases, the hospital challenged several teams, participating in an open innovation program and blockchain hackathon, to find a solution that showed the added value of the technology for patient care and scientific research. Besides this practical perspective, the report also considers literature discussing the current state of blockchain technology in regard to developments in the healthcare domain (touching on patient empowerment, data management, regulations, and interoperability between healthcare systems).

Includes members:
  Member "on the origins and variations of blockchain technologies":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "mind the gap trade offs between distributed ledger technology characteristics")
  Member "conceptualizing blockchains characteristics applications":
    also connected through other hyperedges:
      (none)
  Member "applications of blockchain technology beyond cryptocurrency":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "blockchain enabled smart contract based applications deficiencies with the software development life cycle models")
  Member "secure and trustable electronic medical records sharing using blockchain":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "attribute based multi signature and encryption for ehr management a blockchain based solution")
