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 "spacetime entangled networks i relativity and observability of stepwise consensus"):
  Abstract: Consensus protocols can be an effective tool for synchronizing small amounts of data over small regions. We describe the concept and implementation of entangled links, applied to data transmission, using the framework of Promise Theory as a tool to help bring certainty to distributed consensus. #R##N#Entanglement describes co-dependent evolution of state. Networks formed by entanglement of agents keep certain promises: they deliver sequential messages, end-to-end, in order, and with atomic confirmation of delivery to both ends of the link. These properties can be used recursively to assure a hierarchy of conditional promises at any scale. This is a useful property where a consensus of state or `common knowledge' is required. We intentionally straddle theory and implementation in this discussion.
