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 "an interleaving hybrid consensus protocol"):
  Abstract: We introduce Unity Interleave, a new consensus algorithm for public blockchain settings. It is an eventual consistency protocol merging the Proof-of-Work (PoW) and Proof-of-Stake (PoS) into a coherent stochastic process. It builds upon research previously done for the Unity protocol, improving security while maintaining fairness and scalability.

Includes members:
  Member "a unifying hybrid consensus protocol":
    also connected through other hyperedges:
      (none)
  Member "block arrivals in the bitcoin blockchain":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "all that glitters is not bitcoin unveiling the centralized nature of the btc ip network")
  Member "formal barriers to longest chain proof of stake protocols":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "sok tools for game theoretic models of security for cryptocurrencies")
  Member "cryptocurrencies without proof of work":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "blockchain consensus algorithms a survey")
  Member "majority is not enough bitcoin mining is vulnerable":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "on the convergence of artificial intelligence and distributed ledger technology a scoping review and future research agenda")
