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 "hotpow finality from proof of work quorums"):
  Abstract: We build a bridge between the notions of Byzantine and Nakamoto consensus by developing a theory of proof-of-work quorums. This theory yields stochastic uniqueness of quorums as a function of the quorum size, a security parameter. We employ the theory in HotPoW, a scalable permissionless distributed log protocol that supports finality based on the pipelined three-phase commit previously presented for HotStuff. Additionally, we present a simulation framework for distributed consensus protocols, which we use for evaluating the proposed protocol and variants with adversarial modifications. Results show that the protocol can tolerate network latency, churn, and targeted attacks on consistency and liveness at small overhead compared to deployed systems.
