human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "fork sequential consistency is blocking"
  Abstract: We consider an untrusted server storing shared data on behalf of clients. We show that no storage access protocol can on the one hand preserve sequential consistency and wait-freedom when the server is correct, and on the other hand always preserve fork sequential consistency.

Connected through hyperedge HE-1 (induced by source paper "consistency in non transactional distributed storage systems"):

    - "don t trust the cloud verify integrity and consistency for cloud object stores"
    - "blazes coordination analysis for distributed programs"
    - "probabilistically bounded staleness for practical partial quorums"
    - "toward a principled framework for benchmarking consistency"
    - "using paxos to build a scalable consistent and highly available datastore"
